Description
TECHNICAL FIELD
[0001] The present invention relates to a wet tissue packaging unit
that accommodates and packs a wet tissue continuing material body
formed by a plurality of wet tissues, in an accommodation
container.
BACKGROUND ART
[0002] Hitherto, a wet tissue used for wiping hands or buttocks of
babies, patients, and elderly people is widely known. The wet
tissue is formed by impregnating a chemical solution and the like
into a ground fabric. The wet tissue is accommodated in a sealed
accommodation container so that the ground fabric may be maintained
in a wet state by the chemical solution and the like, and is formed
to be extracted from the accommodation container as needed
basis.
[0003] As the accommodation container, a cylindrical bottle type
container has been widely used from the past. In many cases, the
bottle type accommodation container accommodates a wet tissue
continuing material body which is wound in a roll shape. The wet
tissue continuing material body is provided with separating
portions (i.e., dividing portions) by breaks of perforation lines
or the like at predetermined intervals, and when the wet tissue
continuing material body is divided at the dividing portion by
cutting a part of the wet tissue continuing material body at the
dividing portion or the like, a sheet-like wet tissue is
obtained.
[0004] In recent years, instead of the bottle type wet tissue
packaging unit, a bag type wet tissue packaging unit provided with
a bag-like accommodation container has been used in many cases. The
bag type wet tissue packaging unit accommodates an interfolded wet
tissue continuing material body in a bag body and is formed so that
wet tissues forming the wet tissue continuing material body are
extracted to the outside from an opening which is opened to the bag
body. The opening of the bag body is formed so that a wet tissue is
separated from the wet tissue continuing material body at the
dividing portion formed in the wet tissue continuing material body.
Further, the bag body is generally provided with a lid for opening
and closing the opening. As the lid, for example, a flap-like lid
which is formed by a film material such a material of the bag body
has been widely used (e.g., Patent Literatures 1 and 2).

SUMMARY OF INVENTION
Technical Problem
[0005] In the bag type wet tissue packaging unit formed as
described above, the lid is attached to the vicinity of the surface
of the bag body to close the opening when a user does not extract a
wet tissue. In the wet tissue packaging unit, the inside of the bag
body is kept in a sealed state by the lid such that the chemical
solution and the like impregnated into the wet tissue accommodated
in the bag body are prevented from volatilizing.
[0006] In addition, at a position inside the lid, an extraction
hole which applies a friction resistance to the wet tissue
continuing material body when the wet tissue packaging unit is
drawn out while passing therethrough is formed. Then, when a
predetermined or higher resistance is applied to the wet tissue
continuing material body during the extraction, the wet tissue
continuing material body is divided at the dividing portion, which
is close to the drawing end, due to the resistance.
[0007] However, in the bag type wet tissue packaging unit, when the
wet tissue is consumed, the volume of the wet tissue continuing
material body inside the bag body decreases, the wet tissue
continuing material body easily passes and hence the timing at
which the wet tissue is divided at the dividing portion is delayed.
Then, the front end of the wet tissue continuing material body that
is divided and remains is excessively drawn out from the opening
which has to be sealed by the lid, and the wet tissue packaging
unit may not be reliably sealed. Accordingly, there is a problem in
that the wet tissue may not be maintained in a wet state.
[0008] The present invention is made in view of such problems, and
an object thereof is to provide a wet tissue packaging unit, i.e. a
wet tissue package, capable of further sealing an accommodation
container and maintaining a wet tissue accommodated in the
accommodation container in a wet state.
Solution to Problem
[0009] The present invention may be summarized as below.
[0010] (1) A wet tissue packaging unit including: an accommodation
container that accommodates a wet tissue continuing material body
having a dividing portion formed therein at a predetermined
interval, and includes an opening formed to draw out a wet tissue
divided from the wet tissue continuing material body at the
dividing portion to the outside; an extraction hole forming member
that is attached to the opening of the accommodation container and
includes an extraction hole forming portion having an extraction
hole formed to apply a resistance when the wet tissue continuing
material body passes therethrough and an accommodation space which
accommodates a front end of the wet tissue continuing material body
that passes through the extraction hole; a lid that is provided at
the outside of the accommodation space so as to freely close and
open the accommodation space; and a communicating portion that
allows the accommodation space of the extraction hole forming
member and a space in the accommodation container to communicate
with each other in an area excluding the extraction hole.
[0011] (2) The wet tissue packaging unit according to (1), wherein
the communicating portion is provided in a peripheral edge area of
a bottom portion of the accommodation space.
[0012] (3) The wet tissue packaging unit according to (2), wherein
the extraction hole forming portion is formed in a plate that is
convexly curved toward the inner side of the accommodation
container, and the communicating portion is formed by the convexly
swollen area.
[0013] (4) The wet tissue packaging unit according to any of (1) to
(3), wherein the attachment hole forming portion is supported by
the attachment hole forming member in a cantilevered manner, and
the communicating portion is formed or is widened as a free end of
the attachment hole forming portion is turned toward the internal
space of the accommodation container on the cantilevered portion as
the center.
[0014] (5) The wet tissue packaging unit according to (1), wherein
the extraction hole forming member is attached to the accommodation
container by allowing an attachment surface of the extraction hole
forming member to face an inner surface of the accommodation
container.
Advantageous Effects of Invention
[0015] According to the wet tissue packaging unit of the present
invention, even when the timing at which the wet tissue continuing
material body is divided at the dividing portion is delayed and
hence the extra front end portion of the wet tissue continuing
material body is drawn out and is lengthened in the accommodation
space, the front end portion of the wet tissue continuing material
body may be pushed into the accommodation container through the
communicating portion so as to be relieved. Since the lid is
reliably closed and the accommodation container is sealed, it is
possible to prevent the chemical solution and the like impregnated
into the wet tissue continuing material body accommodated in the
accommodation container from volatilizing. Further, according to
the wet tissue packaging unit of the present invention, it is
possible to provide the wet tissue in a state where the chemical
solution and the like are always impregnated therein for a
user.

DESCRIPTION OF EMBODIMENTS
[0033] The configuration of a first embodiment of a wet tissue
packaging unit, i.e. a wet tissue package, according to the present
invention will be described with reference to FIGS. 1 to 11C.
Further, it is assumed that the up-down direction, the
forward-rearward direction (or front-back direction), and the
right-left direction in the present specification indicate the
up-down direction, the forward-rearward direction, and the
right-left direction illustrated in FIG. 1, respectively.
Furthermore an example, in which a bag body is used as one kind of
accommodation container, is described in the present specification.
Any member other than the bag body may be arbitrarily selected to
be used as the accommodation container. For example, as the
accommodation container, a container that is formed of a resin
material such as plastic may be used. In the present specification,
the "unused item of the wet tissue packaging unit" indicates that a
wet tissue continuing material body, or a continuous body of wet
tissues, accommodated in the accommodation container in the
manufacturing process has never been extracted from the
accommodation container and a partitioning portion and a closing
portion to be described later are not removed.
[0034] As illustrated in FIG. 1, a wet tissue packaging unit 1
according to this embodiment includes a bag body 3 (i.e.,
accommodation container) having an opening 2 that is opened to the
upper portion thereof, an extraction hole forming member 4 which is
attached to the inner surface of the bag body 3 by an arbitrary
method such as hot-melt, and a lid 5 which is attached to the
extraction hole forming member 4. Further, as illustrated in FIG.
2, the wet tissue packaging unit 1 accommodates a wet tissue
continuing material body 6 inside the bag body 3.
[0035] First, the configuration of the wet tissue continuing
material body 6 will be described. In the present specification,
the "wet tissue continuing material body" indicates a wet tissue
continuing material body that is piled in a folded shape by a
method to be described later and is accommodated in the bag body 3,
and a "wet tissue" indicates both a sheet-like tissue separated
from the wet tissue continuing material body 6 and a sheet-like
tissue forming the wet tissue continuing material body 6. This
embodiment and second to fourth embodiments to be described later
are described by using a wet tissue continuing material body that
is piled in a folded shape as an example of the wet tissue
continuing material body, but the configuration of the wet tissue
continuing material body is not limited thereto. For example, as
the wet tissue continuing material body, a body that is wound in a
roll shape or has the other configurations may be used.
[0036] The wet tissue continuing material body 6 is formed by
impregnating a chemical solution and the like into a ground fabric
formed by paper made from synthetic fabric or natural fabric, woven
cloth, or non-woven cloth. As the chemical solution and the like,
alcohol, water, or the mixture thereof may be exemplified. Further,
the chemical solution may be arbitrarily selected from perfume,
antibacterial agent, refresher, surfactant, antiseptic agent,
pigment, antifoam agent, antioxidizing agent, clarifying agent,
solubilizing agent, pH adjuster, and the like and mixed therewith.
Furthermore, the above-described materials of the ground fabric and
the chemical solution and the like forming the wet tissue
continuing material body 6 are merely examples, and the materials
other than the above-described materials may be arbitrarily
selected to be used.
[0037] Structures of the wet tissue continuing material body 6
include both followed structures. In one kind of the structures, a
wet tissue continuing material body is formed so that wet tissues
are connected to each other by the perforation lines or the like,
and in another kind of the structures, a wet tissue continuing
material body that is formed so that each of separate wet tissues
is bent and folded in a Z-shape or the like to be described later
and the plurality of folded wet tissues contact one another. In
addition, in the present specification, the separation of the wet
tissue from the wet tissue continuing material body 6 indicates
that, for example, in a case where the wet tissues are connected by
the perforation lines or the like, the wet tissue continuing
material body 6 is torn at the position of the perforation lines or
the like and a portion that becomes the wet tissue is separated
from the wet tissue continuing material body 6. Further, the
separation indicates that, in a case where the wet tissue
continuing material body 6 is formed to have a structure in which
each of the separate wet tissues is appropriately folded in a
Z-shape to be described later and the plurality of wet tissues
contact one another, the front end of single wet tissue is took off
from the contact portion of the plurality of wet tissues so as to
be separated from the wet tissue continuing material body 6.
Furthermore, a portion where the wet tissue is separated from the
wet tissue continuing material body 6 is called a dividing
portion.
[0038] A specific example of the wet tissue continuing material
body 6 will be described. The wet tissue continuing material body 6
illustrated in FIGS. 3A and 3B includes first turnback portions 8
and second turnback portions 9 as a plurality of turnback portions
and is piled in a continuously folded shape. The wet tissue
continuing material body 6 is provided with separating portions 10
(i.e., dividing portions) at predetermined intervals. The
separating portion 10 is formed to be separated (i.e., divided) by
a tensile force that is applied when the front end of the wet
tissue continuing material body 6 is drawn out. FIG. 3A illustrates
an example of the separating portion 10 of the wet tissue
continuing material body 6 according to this embodiment. The
separating portion 10 is formed to be separated by a tensile force
applied to the wet tissue continuing material body 6 when the front
end of the wet tissue continuing material body 6 is drawn out. As
illustrated in FIG. 3A, the separating portion 10 is provided with
a plurality of spaces 11 at predetermined intervals in the
right-left direction of the wet tissue continuing material body 6,
and connecting portions 12 which connect the wet tissues 7 forming
the wet tissue continuing material body 6 are formed between the
spaces 11. In this embodiment, the connecting portions 12 are
formed at three positions with respect to the right-left direction
of the wet tissue continuing material body 6, but the shape of the
connecting portion 12 is not limited thereto. Further, the
separating portion 10 may be formed to be separated when a tensile
force is applied thereto. For example, the separating portion 10
may be formed in a perforation line shape by reducing the interval
between the space 11 and the connecting portion 12 or in the other
shapes.
[0039] FIG. 3B is an explanatory view illustrating where the
separating portion 10 is located in the wet tissue continuing
material body 6. In this drawing, the points indicated by black
circles represent the positions of the separating portions 10. As
illustrated in FIG. 3B, the wet tissue continuing material body 6
is formed so that the separating portion 10 is located at the
center portion between the first turnback portion 8 and the second
turnback portion 9, and as the vertical relation, a portion with
the separating portion 10 and a portion without the separating
portion 10 are alternated.
[0040] In the above-described example, the case where the
separating portion 10 is formed as the dividing portion in the wet
tissue continuing material body 6. However, the shape of the wet
tissue continuing material body 6 is not limited thereto and may be
formed in the other shapes. Specifically, as exemplified below, the
wet tissue continuing material body 6 may be formed so that a
predetermined portion where two folded separate wet tissues overlap
each other becomes the separating portion (i.e., the dividing
portion). An example of the configuration of another shape of the
wet tissue continuing material body 6 is illustrated in FIGS. 4A
and 4B. FIG. 4A illustrates a wet tissue continuing material body
which is folded in a so-called Z-shape, and FIG. 4B illustrates the
configuration of a wet tissue continuing material body which is
folded in a so-called WZ-shape. Further, the structure of folding
the wet tissue continuing material body 6 may be a structure in
which when a wet tissue 7 is raised, the next wet tissues 7 are
sequentially and continuously raised, and after the wet tissue 7 is
divided from the next wet tissue 7, the next wet tissue 7 is in the
state in which its end pops up from an extraction hole 26 to be
described later (hereinafter, this state is referred to as
"pop-up"). The configuration may also have a W-shape or the other
shapes other than the above-described Z-shape and the WZ-shape.
[0041] As illustrated in FIG. 4A, the wet tissue continuing
material body 6 having a Z-shaped folded structure is formed by a
plurality of layered wet tissues which are respectively folded in a
Z-shape. In addition, the wet tissue continuing material body 6
having the Z-shaped folded structure is piled so that an upper
surface 7c of a termination end of a wet tissue 7a overlaps a lower
surface 7d of a start end of the next wet tissue 7b. When the wet
tissue 7a is drawn out, the termination end of the wet tissue 7a
acts to raise the start end of the next wet tissue 7b. Then, when
the start end of the next wet tissue 7b is drawn out from the
extraction hole 26 to be described later to the upper portion of
the extraction hole 26, the termination end of the wet tissue 7a
and the start end of the next wet tissue 7b are divided from each
other. That is, a portion where the termination end of the wet
tissue 7a and the start end of the next wet tissue 7b overlap forms
the separating portion (i.e., the dividing portion), and the wet
tissue 7a is separated from the wet tissue continuing material body
6 having the next wet tissue 7b at the dividing portion.
[0042] As illustrated in FIG. 4B, the wet tissue continuing
material body 6 having a WZ-shaped folded structure is formed by
alternately piling a wet tissue 7e folded in a Z-shape and a wet
tissue 7f folded in a W-shape. In the case of FIG. 4B, the wet
tissue continuing material body 6 is piled so that an upper surface
7g of a termination end of a wet tissue 7e folded in a Z-shape
overlaps a lower surface 7h of a start end of the next wet tissue
7f folded in a W-shape. When the wet tissue 7e folded in a Z-shape
is drawn out, the termination end of the wet tissue 7e acts to
raise the start end of the next wet tissue 7f folded in a W-shape.
Then, when the start end of the wet tissue 7f folded in a W-shape
is drawn out from the extraction hole 26 to be described later to
the upper portion of the extraction hole 26, the termination end of
the wet tissue 7e folded in a Z-shape and the start end of the wet
tissue 7f folded in a W-shape are divided from each other.
Furthermore, the wet tissue is raised by the same operation even
when the start end of a wet tissue 7i folded in a Z-shape is drawn
out after the wet tissue 7f folded in a W-shape is drawn out. That
is, a portion where the termination end of the wet tissue 7e
overlaps the start end of the next wet tissue 7f and a portion
where the termination end of the wet tissue 7f overlaps the start
end of the next wet tissue 7i form the separating portions (i.e.,
the dividing portions), and the wet tissues 7e and 7f are separated
from the wet tissue continuing material body 6 having the next wet
tissues 7f and 7i at the dividing portions.
[0043] Furthermore, the configuration of the wet tissue continuing
material body 6 is not limited to the above-described
configuration. The configuration of the wet tissue continuing
material body 6 may be formed in any shape as long as the wet
tissue continuing material body may be accommodated in the bag body
3. For example, in this embodiment, the position of the separating
portion 10 is located at the center portion between the first
turnback portion 8 and the second turnback portion 9. However, the
separating portion 10 may be disposed at a position other than the
center portion. Further, the separating portion 10 may be disposed
at a position where the first turnback portion 8 or the second
turnback portion 9 is formed. Further, in this embodiment, as for
the vertical relation of the wet tissue continuing material body 6,
a portion with the separating portion 10 and a portion without the
separating portion 10 are alternated. However, the portions with
the separating portion 10 may overlap each other in the up-down
direction. Further, the separating portion 10 may be located at
both positions where the first turnback portion 8 and the second
turnback portion 9 are formed. Furthermore, the separating portion
may have a configuration other than the above-described
configuration.
[0044] Next, the configuration of the bag body 3 will be described.
The bag body 3 is an accommodation container that accommodates the
wet tissue continuing material body 6 therein. The bag body 3 is
formed in, for example, a pillow-like bag shape by a plastic film
having air-tightness and flexibility or the like. As illustrated in
FIG. 1, the bag body 3 is formed so that both ends in the
forward-rearward direction are air-tightly sealed by heat-seal or
the like.
[0045] As illustrated in FIG. 2, the bag body 3 is formed in a
double-layer structure with an inner layer 13 and an outer layer
14. In the inner layer 13, for example, a film formed of plastic
such as polyethylene, polypropylene, polyester, polyamide, vinyl
chloride, vinylidene chloride, and cellophane, a laminate film
formed of two or more of these materials, or a complex film formed
by laminating an aluminum foil on these single or complex laminate
films may be used. In the outer layer 14, for example, a
polyethylene terephthalate (PET) film may be used. Furthermore, in
this embodiment, the bag body 3 formed by two layers, that is, the
inner layer 13 and the outer layer 14 is used, but the structure of
the bag body 3 is not limited thereto. For example, the bag body 3
may be formed as a multi-layer structure having three or more
layers or a single-layer structure. Further, the materials of the
inner layer 13 and the outer layer 14 are not limited to the
above-described materials.
[0046] As illustrated in FIGS. 1 and 2, the bag body 3 is provided
with an opening 2. Through the opening 2, the wet tissue 7
separated from the wet tissue continuing material body 6 that is
accommodated in the bag body 3 as the accommodation container is
drawable to the outside. In this embodiment, the opening 2 is
formed as a square opening in the upper portion of the bag body 3,
but the shape of the opening 2 is not limited thereto. Further, the
opening 2 may be formed to allow the wet tissue 7 to be drawable
therethrough to the outside, and the size of the opening 2 may be
arbitrarily adjusted.
[0047] As illustrated in FIG. 2, the extraction hole forming member
4 is attached to the inside of the bag body 3. The extraction hole
forming member 4 is disposed at such a position that the positions
of a pinching hole 22 to be described later and the extraction hole
26 coincide with the position of the opening 2 of the bag body 3 so
as to align themselves. As a method of attaching the extraction
hole forming member 4 to the bag body 3, for example, a method
using hot-melt or the like may be exemplified, but the present
invention is not limited thereto, and various methods may be
arbitrarily selected. Further, in the present specification, the
description is provided by using the example in which the
extraction hole forming member is disposed at the position so that
the positions of the pinching hole and the extraction hole coincide
with the position of the opening of the bag body so as to align
themselves. The positions of the pinching hole, the extraction
hole, and the opening may not coincide with each other.
[0048] As illustrated in FIG. 5A, the extraction hole forming
member 4 and the lid 5 according to this embodiment may be
integrally molded with each other through a hinge portion 5a.
[0049] For example, the extraction hole forming member 4 is formed
of a thermoplastic resin material such as polyethylene and
polypropylene. In this embodiment, the description is provided by
using the extraction hole forming member 4 which is integrally
molded by an injection molding method or the like, but the
extraction hole forming member 4 may also be formed by the
combination of the separately molded members. Further, the
extraction hole forming member 4 may be formed by a method other
than the above-described method.
[0050] As illustrated in FIGS. 5A, 5B, and 6A, the extraction hole
forming member 4 includes a base plate 21 as a base portion for
attaching the extraction hole forming member 4 to the bag body 3,
an accommodation space 23 which accommodates a front end 6a, or a
leading end 6a, of the wet tissue continuing material body 6
through the pinching hole 22 through which the wet tissue 7 is
drawn out from the bag body 3, and an extraction hole forming
portion 27 having the extraction hole 26 which is opened to
separate the wet tissue 7 at the separating portion 10 of the wet
tissue continuing material body 6.
Further, the extraction hole forming member 4 provided in this
example includes a partitioning portion 24 and a fragile portion
25. The partitioning portion 24 is provided or arranged to close
the pinching hole 22 and partitions the accommodation space 23 into
a plurality of sections. The fragile portion 25 is formed at the
peripheral edge portion of the partitioning portion 24 and is
broken when a predetermined shear force is applied thereto.
[0051] The base plate 21 is formed in a flat square plate shape,
and is formed so that the upper surface thereof becomes an
attachment surface when the base plate 21 is attached to the inner
surface of the bag body 3. The reference numeral 28 of FIG. 5A
indicates the attachment surface. In the state where the extraction
hole forming member 4 is attached to the bag body 3, the attachment
surface 28 provided in the base plate 21 faces the inner surface of
the bag body 3. Further, the base plate 21 is integrally molded
with the lid 5 through the hinge portion 5a. The base plate 21 is
provided with an extraction concave portion 29 at the substantially
center portion thereof. The extraction concave portion 29 is formed
in a concave shape so that the position thereof in the height
direction is lower than the position of the base plate 21 at one
step lower. Further, the extraction concave portion 29 is formed in
a circular shape in the top view of the extraction hole forming
member 4.
[0052] A vertical wall portion 30 is uprightly formed in the
extraction concave portion 29. The vertical wall portion 30 is
formed in a circular shape in the top view of the extraction hole
forming member 4. Further, the vertical wall portion 30 is formed
so that the outer diameter of the vertical wall portion 30 is
smaller than the inner diameter of the extraction concave portion
29. Furthermore, the vertical wall portion 30 is formed at a
position where the center position of an inner wall 29a of the
extraction concave portion 29 coincides with the center position of
the vertical wall portion 30. That is, the vertical wall portion 30
is formed so that a circle drawn by the inner wall 29a of the
extraction concave portion 29 is concentric with a circle drawn by
the vertical wall portion 30. Further, as illustrated in FIGS. 7A
and 7B, the vertical wall portion 30 is formed so that the position
of the upper surface thereof in the height direction is lower than
the position of the upper surface of the base plate 21 in the
height direction and when the lid 5 is closed, the upper surface of
the lid 5 and the upper surface of the base plate 21 are
substantially flush with each other. In the present specification,
the description is provided by using the example in which the
center position of the vertical wall portion 30 coincides with the
center position of the inner wall 29a, but the positions thereof
may not coincide with each other.
[0053] As illustrated in FIG. 6A, the pinching hole 22 allows a
user to pinch the front end 6a of the wet tissue continuing
material body 6 forming the wet tissues 7 when the user extracts
the wet tissue 7 so that the wet tissue 7 is drawn out from the bag
body 3. The pinching hole 22 is opened to the inner peripheral side
of the vertical wall portion 30. The pinching hole 22 is formed in
a size in which the user may pinch the front end 6a of the wet
tissue continuing material body 6 accommodated in the bag body 3
with a finger to extract the front end 6a. In this embodiment, the
hole diameter of the pinching hole 22 is substantially the same as
the inner diameter of the vertical wall portion 30. Further, the
hole diameter of the pinching hole 22 may be determined so that the
user may pinch the front end 6a of the wet tissue continuing
material body 6 with a finger to extract the front end 6a, and is
not limited to the size and shape of this embodiment. That is,
sizes and shapes may be arbitrarily selected. For example, when the
pinching hole 22 is formed to be large, the user easily inserts a
finger into the pinching hole 22, and hence the front end 6a of the
wet tissue continuing material body 6 is easily drawn out during
the drawing, thereby enhancing handleability. In contrast, when the
pinching hole 22 is formed to be small, the extraction hole forming
member 4 may be decreased in size, and the manufacturing cost of
the extraction hole forming member 4 may be largely reduced. The
shape of the pinching hole in the top view of the pinching hole may
be a shape other than a circular shape.
[0054] As illustrated in FIG. 5B, in a case where the wet tissue
packaging unit 1 is the unused item, the pinching hole 22 is closed
by the partitioning portion 24 to be described later and is opened
by removing the partitioning portion 24 as illustrated in FIG.
6A.
[0055] The accommodation space 23 accommodates the front end 6a of
the wet tissue continuing material body 6 through the pinching hole
22 and is a space indicated by the dotted line in FIG. 7B. The
accommodation space 23 is sealed together with the internal space
of the bag body 3, with a gap, when the lid 5 is closed. Regarding
the wet tissue packaging unit 1, in the case where the wet tissue
packaging unit 1 is the unused item, the pinching hole 22 is closed
by the partitioning portion 24. Therefore, the accommodation space
23 is partitioned into a space that communicates with the inside of
the bag body 3 and a space that communicates with the outside of
the bag body 3 by the partitioning portion 24. Further, when the
partitioning portion 24 is removed and the pinching hole 22 is
opened, the accommodation space 23 is formed as a space indicated
by the dotted line in FIG. 7B.
[0056] The partitioning portion 24 partitions the bag body 3 into
the inside and the outside by closing the pinching hole 22.
Further, the partitioning portion 24 also separates the
accommodation space 23 into the space that communicates with the
inside of the bag body 3 and the space that communicates with the
outside of the bag body 3. As illustrated in FIGS. 5B and 7A, the
partitioning portion 24 is formed on the inner peripheral side of
the vertical wall portion 30. Further, a tab 31 is integrally
formed with the upper portion of the partitioning portion 24. The
tab 31 is formed in an annular shape and is formed so that a part
of the inner portion thereof is connected to the partitioning
portion 24.
[0057] The fragile portion 25 is provided in the peripheral edge
portion of the partitioning portion 24. As illustrated in FIG. 7A,
the fragile portion 25 is formed at the peripheral edge portion of
the partitioning portion 24 in a groove shape that is thinner than
a thickness of the partitioning portion 24, and is formed to be
broken by a stress that occurs due to a predetermined shear force
when the shear force is applied. Here, the "predetermined shear
force" is a force having a conventionally well-known magnitude
needed for the shear failure of the fragile portion 25 provided at
the peripheral edge portion of the partitioning portion 24.
[0058] The extraction hole forming portion 27 separates the wet
tissue 7 at the separating portion 10 provided in the wet tissue
continuing material body 6 and allows the front end 6a of the wet
tissue continuing material body 6 to pop up. As illustrated in
FIGS. 2 and 6B, the extraction hole forming portion 27 is formed in
a plate shape that is convexly curved toward the inner side of the
bag body 3 and has a pair of leg portions 32a and 32b at both ends
of the curved end. Further, the pair of leg portions 32a and 32b is
integrally formed with the base plate 21 on the lower side of the
base plate 21 and is hence integrally formed with the base plate
21. The extraction hole forming portion 27 is disposed on the lower
side of the base plate 21 so that the extraction hole 26 is located
below a point where the extraction concave portion 29 of the base
plate 21 is formed. Furthermore, the extraction hole forming
portion 27 is formed in a curved shape.
[0059] As illustrated in FIG. 6B, in the extraction hole forming
portion 27, the extraction hole 26 is opened to the substantially
center portion of the extraction hole forming portion 27 in the
forward-rearward direction. The extraction hole 26 is formed in an
elongated hole shape that extends in the right-left direction. The
extraction hole 26 is formed in a size in which, when the front end
6a of the wet tissue continuing material body 6 or the like passes
therethrough, a friction resistance can be applied to the wet
tissue continuing material body 6 that passes therethrough.
Further, in the extraction hole forming portion 27, a first slit 33
and a second slit 34 are respectively provided in both ends of the
extraction hole 26 in the forward-rearward direction with respect
to the extraction hole 26. The first and second slits 33 and 34 are
formed in elongated hole shapes that extend in the right-left
direction, and the widths thereof in the forward-rearward direction
are smaller than the width of the extraction hole 26 in the
forward-rearward direction. Furthermore, the first and second slits
33 and 34 are formed so that the widths of the first and second
slits 33 and 34 are the same. The first and second slits 33 and 34
are also formed so that, when the front end 6a of the wet tissue
continuing material body 6 passes therethrough, a resistance can be
applied to the front end 6a of the wet tissue continuing material
body 6 that passes therethrough.
[0060] Furthermore, in the extraction hole forming portion 27, a
first protruding piece 35 is provided between the extraction hole
26 and the first slit 33, and a second protruding piece 36 is
provided between the first slit 33 and the second slit 34. The
first protruding piece 35 includes a left protruding piece 35a that
extends from the left to the right and a right protruding piece 35b
that extends from the right to the left, and a first void 37 is
provided between the left protruding piece 35a and the right
protruding piece 35b. Further, the second protruding piece 36
includes a left protruding piece 36a that extends from the left to
the right and a right protruding piece 36b that extends from the
right to the left, and a second void 38 is provided between the
left protruding piece 36a and the right protruding piece 36b. The
first and second voids 37 and 38 are formed to be located on the
substantially same straight line in the right-left direction.
[0061] As illustrated in FIGS. 2 and 6A, the extraction hole
forming member 4 is provided with a relief portion 39 (i.e.,
communicating portion or linking part). The relief portion 39
allows a portion of the front end 6a which is not accommodated in
the accommodation space 23 to be pushed into the bag body 3 so as
to be relieved when the front end 6a of the wet tissue continuing
material body 6 is pushed into the accommodation space 23. The
relief portion 39 is formed to be surrounded by the base plate 21,
the extraction hole forming portion 27 that is convexly curved, and
the leg portions 32a and 32b and is formed as a communicating
portion that allows the accommodation space 23 and the internal
space of the bag body 3 to communicate with each other in an area
excluding the extraction hole 26 and the like. The relief portion
39 is formed in a convexly curved shape by both sides of a portion
of a plate-like attachment hole forming portion that is swollen or
expanded in a convex shape. Further, in this embodiment, each of
the relief portions 39 is formed in the leftward direction and in
the rightward direction, but the points where the relief portions
39 are formed may be, for example, points in the forward direction
and in the rearward direction, or the other positions. Furthermore,
the size of the relief portion 39 may be arbitrarily selected to be
used as long as the front end 6a of the wet tissue continuing
material body 6 may move between the accommodation space 23 and the
internal space of the bag body 3. The number of relief portions 39
may also be arbitrarily selected.
[0062] Furthermore, the extraction hole forming portion 27 of this
embodiment is integrally formed with the pair of leg portions 32a
and 32b and the base plate 21, but may also be formed separately
from the base plate or have the other structures.
[0063] The lid 5 is provided on the extraction hole forming member
4 in an openable and closable manner and is configured to close or
open the accommodation space 23 provided in the extraction hole
forming member 4. Further, the extraction hole forming member 4 and
the lid 5 may be molded separately from each other, and may also be
molded integrally with each other by a structure other than hinges
in a case where they are formed integrally with each other. The lid
5 is formed of the same material as that of the extraction hole
forming member 4, for example, a thermoplastic resin material such
as polyethylene and polypropylene.
[0064] As illustrated in FIG. 6A, the lid 5 is formed integrally
with the extraction hole forming member 4 through the hinge portion
5a. The shape of the lid 5 is formed as a circular shape in the top
view of the lid 5. Further, a side wall 41 is provided in the
peripheral edge portion of the lid 5. The side wall 41 is formed
along the peripheral edge portion in the plan view of the lid 5. In
this embodiment, the side wall 41 is formed in a circular shape.
The side wall 41 is formed so that the center position thereof when
the lid 5 is closed is at the same position as those of the
pinching hole 22 and the extraction hole 26. Furthermore, the side
wall 41 is formed so that the inner diameter thereof is
substantially the same as the outer diameter of the vertical wall
portion 30 or greater than the outer diameter of the vertical wall
portion 30 so that the inside of the bag body 3 may be sealed by
fitting the outer peripheral surface of the vertical wall portion
30 with the inner peripheral surface of the side wall 41 when the
lid 5 is closed.
[0065] Next, in the wet tissue packaging unit 1 according to this
embodiment, a procedure of removing the partitioning portion 24
will be described. In a case where the wet tissue packaging unit 1
according to this embodiment is an unused item that the user does
not use yet, as illustrated in FIG. 8A, the partitioning portion 24
of the extraction hole forming member 4 is present. In this case,
the pinching hole 22 is closed by the partitioning portion 24, and
the accommodation space 23 is also partitioned by the partitioning
portion 24. Further, the lid 5 is generally closed, but a state
where the lid 5 is opened is illustrated in FIG. 8A.
[0066] When the user initially uses the wet tissue packaging unit
1, first, the partitioning portion 24 is removed. In the case of
removing the partitioning portion 24, the user pinches the tab 31
with a finger and applies a force in the A direction in FIG. 8B. In
this case, since the tab 31 is disposed above the partitioning
portion 24, when the user applies the force in the A direction, a
force in the B direction is applied to the partitioning portion 24.
The force in the B direction is applied to the fragile portion 25
as shear force.
[0067] When the shear force in the B direction is applied to the
fragile portion 25 by the force in the A direction applied by the
user, since the fragile portion 25 is formed to be thinner than the
partitioning portion 24, a stress applied to the fragile portion 25
becomes greater than a stress applied to positions other than the
fragile portion 25. Therefore, the fragile portion 25 is likely to
undergo shear failure, and undergoes shear failure when a
predetermined stress is applied thereto such that the partitioning
portion 24 is removed from the extraction hole forming member 4.
The fragile portion 25 gradually undergoes shear failure from the
position to which the predetermined shear force is applied and the
entire fragile portion 25 finally undergoes shear failure. When the
shear failure of the entire fragile portion 25 occurs, as
illustrated in FIG. 8C, the partitioning portion 24 is removed such
that the pinching hole 22 is opened.
[0068] As illustrated in FIG. 8C, when the partitioning portion 24
is removed as described above, the pinching hole 22 is opened and
the accommodation space 23 which has been partitioned by the
partitioning portion 24 is formed as a space. When the partitioning
portion 24 is removed as described above, the front end 6a of the
wet tissue continuing material body 6 that is accommodated in the
bag body 3 may be extracted.
[0069] Next, a procedure of drawing out the wet tissue continuing
material body 6 by the user will be described. When the pinching
hole 22 is opened in the above-described procedure, the extraction
hole forming portion 27 and the extraction hole 26 of the
extraction hole forming member disposed inside the bag body 3 are
visible through the pinching hole 22 from the outside of the bag
body 3. This is because the extraction hole forming member 4 is
attached at the position which coincides with the position of the
pinching hole 22 in the forward-rearward and right-left directions
and the position of the opening 2 of the bag body 3 in the
forward-rearward and right-left directions.
[0070] As illustrated in FIG. 9A, in the wet tissue packaging unit
1, there may be cases where the front end 6a of the wet tissue
continuing material body 6 is not drawn above the extraction hole
26 of the extraction hole forming portion 27. For example, there is
a case where the wet tissue packaging unit 1 is an unused item, and
a case where the front end 6a of the wet tissue continuing material
body 6 inside the bag body 3 does not pop up but falls below the
extraction hole forming portion 27.
[0071] In these cases, the user draws out the front end 6a of the
wet tissue continuing material body 6. When the front end 6a is
drawn, the user puts a finger into the pinching hole 22 which is
opened in the precedent procedure and pushed down the extraction
hole forming portion 27 or the like to move the extraction hole
forming member 4 (including the upper portion of the bag body 3) in
the C direction in FIG. 9A so as to allow the lowest portion of the
lower end surface of the extraction hole forming portion 27 to
approach the upper surface of the wet tissue continuing material
body 6. Further, in FIG. 9A, regarding the extraction hole forming
member indicated by the two-dotted chain line, as an example in
which the lowest portion is caused to approach the upper surface of
the wet tissue continuing material body 6, a state where the lowest
portion of the lower end surface of the extraction hole forming
portion 27 is brought into contact with the upper surface of the
wet tissue continuing material body 6 is illustrated.
[0072] Next, as illustrated in FIG. 9B, the user pinches the front
end 6a of the wet tissue continuing material body 6 with the
fingertip to raise it through the extraction hole 26. At this time,
it is desirable that the end portion of the front end 6a of the wet
tissue continuing material body 6 be located to extend in the
forward-rearward direction and be located at substantially the
center portions of the pinching hole 22 and the extraction hole 26
in the right-left direction. The wet tissue continuing material
body 6 raised through the extraction hole 26 is drawn out while
widening in the forward-rearward and right-left directions as
illustrated in FIG. 10. Therefore, a portion of the wet tissue
continuing material body 6 which widens in the forward-rearward
direction passes through the first and second voids 37 and 38 and
the first and second slits 33 and 34 other than the extraction hole
26, and is drawn above the extraction hole forming member 4.
Further, in the following description, the extraction hole 26, the
first void 37, the second void 38, the first slit 33, and the
second slit 34 may be referred to as "the extraction hole 26 and
the like". Furthermore, in the concept of the present invention,
"the extraction hole 26 and the like" are referred to as "the
extraction hole".
[0073] At this time, the wet tissue continuing material body 6 is
drawn out while applying a force in the D direction (FIG. 11A) to
the first and second protruding pieces 35 and 36 by a resistance
that occurs between the first and second protruding pieces 35 and
36. Therefore, while the wet tissue continuing material body 6 is
drawn out, the force in the D direction is applied to the first and
second protruding pieces 35 and 36 such that the first and second
protruding pieces 35 and 36 are elastically deformed by the force
in the D direction.
[0074] As illustrated in FIG. 11B, when the separating portion 10
in the wet tissue continuing material body 6 passes through the
extraction hole 26 and the like, a force in the E direction in FIG.
11B is applied to the front end 6a of the wet tissue continuing
material body 6 (the wet tissue 7) on the side lower than the
separating portion 10 by the resistance applied when passing
through the extraction hole 26 and the like and the restoring
forces of the first and second protruding pieces 35 and 36. On the
other hand, a force in the F direction in FIG. 11B which is applied
as the user raises the wet tissue 7 is applied to the wet tissue 7
on the side upper than the separating portion 10. Therefore, the
force in the E direction and the force in the F direction are
applied to the separating portion 10 such that the wet tissue 7 on
the side upper than the separating portion 10 is separated from the
wet tissue 7 on the side lower than the separating portion 10 and
the wet tissue 7 on the side upper than the separating portion 10
is extracted to the outside of the bag body 3 as a single
sheet-like wet tissue 7. Further, the wet tissue 7 on the side
lower than the separating portion 10 becomes a wet tissue 7 forming
the front end 6a of the wet tissue continuing material body 6 after
being separated.
[0075] The wet tissue 7 forming the front end 6a of the wet tissue
continuing material body 6 after the separation does not receive
the force in the F direction which has been applied by the user in
FIG. 11B and thus, tries to move in the G direction in FIG. 11C. At
this time, a resistance is applied to the front end 6a when passing
through the extraction hole 26 and the like. The resistance at this
time is applied in the opposite direction to the G direction in
which the wet tissue 7 forming the front end 6a tries to move, and
the magnitude of the resistance balances with the magnitude of the
force applied when the wet tissue 7 tries to move in the G
direction such that the front end 6a of the wet tissue 7 becomes a
pop-up state in which the front end 6a is kept in a state of being
positioned above the extraction hole forming portion 27. Further,
in a case where the front end 6a of the wet tissue continuing
material body 6 is not entirely accommodated in the accommodation
space 23 at this time, a portion of the front end 6a moves to the
internal space of the bag body 3 through the relief portion 39.
[0076] After extracting the wet tissue 7, the user closes the lid 5
to seal the bag body 3. When the wet tissue 7 is to be extracted
thereafter, the user may open the lid 5 again, insert a finger into
the pinching hole 22, pinch the front end 6a of the wet tissue
continuing material body 6 which has already popped up and draw out
the wet tissue continuing material body 6. Then, the wet tissue 7
is separated at the separating portion 10 by the same operation as
described above such that the sheet-like wet tissue 7 is drawn
out.
[0077] When the wet tissue 7 is extracted again, even in a case
where the front end 6a of the wet tissue continuing material body 6
has not popped up, the wet tissue 7 may be drawn out in the same
order described above.
[0078] In the wet tissue packaging unit 1 according to this
embodiment, as the wet tissues 7 are drawn out, the volume of the
wet tissue continuing material body 6 decreases. However, in the
wet tissue packaging unit 1 according to this embodiment, the lid 5
is formed in an openable and closable manner with respect to the
extraction hole forming member 4. Therefore, even when the volume
of the wet tissue continuing material body 6 accommodated in the
bag body 3 decreases, the lid 5 may be closed to seal the bag body
3. Therefore, according to the wet tissue packaging unit 1
according to this embodiment, the bag body 3 is prevented from not
being maintained in the sealed state and thus the chemical solution
and the like impregnated into the wet tissue continuing material
body 6 (the wet tissue 7) are prevented from volatilizing.
Accordingly, it is possible to provide the wet tissue 7 in a state
where the chemical solution and the like are always impregnated
therein for the user.
[0079] Further, according to the wet tissue packaging unit 1
according to this embodiment, in the case where the wet tissue
packaging unit 1 is the unused item, the pinching hole 22 is closed
by the partitioning portion 24. To use the wet tissue packaging
unit 1, the fragile portion 25 provided in the peripheral edge
portion of the partitioning portion 24 is broken to remove the
partitioning portion 24 and open the pinching hole 22, and
thereafter the front end 6a of the wet tissue continuing material
body 6 is pinched. Accordingly, it is possible to very easily
determine whether or not the wet tissue packaging unit 1 is the
unused item according to the presence or absence of the
partitioning portion 24. Therefore, when using the wet tissue
packaging unit 1 or purchasing the wet tissue packaging unit 1, it
is possible for the user to use or purchase the wet tissue
packaging unit 1 after determining whether or not the wet tissue
packaging unit 1 is the unused item.
[0080] Furthermore, according to the wet tissue packaging unit 1
according to this embodiment, since the extraction hole forming
member 4 provided with the lid 5 is attached to the inner surface
of the bag body 3, during the manufacture, it is possible to
manufacture the wet tissue packaging unit 1 without a process of
attaching the lid 5 after attaching the extraction hole forming
member 4 to the bag body 3. Therefore, according to the wet tissue
packaging unit 1 according to this embodiment, the number of
processes may be reduced during the manufacture and hence it is
possible to largely reduce the manufacturing cost. Furthermore, the
wet tissue packaging unit 1 according to this embodiment includes
the relief portion which allows the accommodation space 23 and the
internal space of the bag body 3 to communicate with each other.
Accordingly, when the front end 6a of the wet tissue continuing
material body 6 is to be accommodated in the accommodation space
23, in a case where the front end 6a is not entirely accommodated
only in the accommodation space 23, a portion of the front end 6a
may be relieved to the inside of the bag body 3 through the relief
portion. Therefore, according to the wet tissue packaging unit 1
according to this embodiment, the bag body 3 may be always sealed
by closing the lid 5 regardless of the pop-up amount of the front
end 6a of the wet tissue continuing material body 6, and hence it
is possible to prevent the chemical solution and the like
impregnated into the wet tissue continuing material body 6 (the wet
tissue 7) from volatilizing.
[0081] Next, a second embodiment of the wet tissue packaging unit
according to the present invention will be described with reference
to FIGS. 12A and 12B. Further, the description of the same
components as those of the first embodiment will not be repeated
and the same reference numerals are used in the description of the
second embodiment.
[0082] The wet tissue packaging unit according to this embodiment
is different from that of the first embodiment described above in
the structure of the extraction hole forming member, and hence the
structure of the extraction hole forming member will now be
described.
[0083] An extraction hole forming member 51 according to this
embodiment is attached at a position where the positions of an
extraction hole 54 and the opening 2 of the bag body 3 coincide
with each other on the inner side of the bag body 3. As a method of
attaching the extraction hole forming member 51 to the bag body 3,
for example, a method using hot-melt or the like may be
exemplified, but the present invention is not limited thereto. That
is, various methods may be arbitrarily selected.
[0084] For example, the extraction hole forming member 51 may be
formed of a thermoplastic resin material such as polyethylene and
polypropylene. In this embodiment, the description is provided by
using the extraction hole forming member 51 which is integrally
molded by an injection molding method or the like, but the
extraction hole forming member 51 may also be formed by the
combination of the separately molded members. Further, the
extraction hole forming member 51 may be formed by a method other
than the above-described method.
[0085] As illustrated in FIG. 12A, the extraction hole forming
member 51 includes a base plate 52 as a base portion for attaching
the extraction hole forming member 51 to the bag body 3, an
accommodation space 53 which can accommodate the front end of the
wet tissue continuing material body, and an extraction hole 54
through which the wet tissue continuing material body is separated
at the separating portion of the wet tissue continuing material
body. Further, the extraction hole forming member 51 illustrated in
this example includes a closing portion 55 which is provided to
close the extraction hole 54 and a fragile portion 56 which is
formed at the peripheral edge portion of the closing portion 55 and
is broken when a predetermined shear force is applied thereto.
[0086] The base plate 52 is formed in a flat square plate shape,
and is formed so that the upper surface thereof becomes an
attachment surface when the base plate 52 is attached to the inner
surface of the bag body. The reference numeral 57 of FIG. 12A
indicates the attachment surface. In the state where the extraction
hole forming member 51 is attached to the bag body, the attachment
surface 57 provided in the base plate 52 faces the inner surface of
the bag body. Further, the upper surface of the base plate 52 is
integrally molded with the lid 5 through the hinge portion 5a. The
base plate 52 is provided with an extraction concave portion 58 at
the substantially center portion thereof. The extraction concave
portion 58 is formed in a concave shape so that the position
thereof in the height direction is lower than the position of the
base plate 52 at one step lower. Further, the extraction concave
portion 58 is formed in a circular shape in the top view of the
extraction hole forming member 51.
[0087] A vertical wall portion 59 is uprightly formed in the
extraction concave portion 58. The vertical wall portion 59 is
formed in a circular shape in the top view of the extraction hole
forming member 51. Further, the vertical wall portion 59 is formed
so that the outer diameter of the vertical wall portion 59 is
smaller than the inner diameter of the extraction concave portion
58. Furthermore, the vertical wall portion 59 is formed at a
position where the center position of an inner wall of the
extraction concave portion 58 coincides with the center position of
the vertical wall portion 59. That is, the vertical wall portion 59
is formed so that a circle drawn by the inner wall of the
extraction concave portion 58 is concentric with a circle drawn by
the vertical wall portion 59. Further, the vertical wall portion 59
is formed so that the position of the upper surface thereof in the
height direction is lower than the position of the upper surface of
the base plate 52 in the height direction and when the lid 5 is
closed, the upper surface of the lid 5 and the upper surface of the
base plate 52 substantially are flush with each other.
[0088] The accommodation space 53 is a space formed to accommodate
the front end 6a of the wet tissue continuing material body 6. The
accommodation space 53 is sealed when the lid 5 is closed. The
accommodation space 53 is surrounded by the lid 5, the closing
portion 55, and the vertical wall portion 59 when the wet tissue
packaging unit 1 is the unused item and the lid 5 is closed.
Further, when the lid 5 is closed in a case of a used item in which
the closing portion 55 is formerly removed, the accommodation space
53 is formed to be surrounded by the lid 5 and the vertical wall
portion 59 and to communicate with the internal space of the bag
body 3 through the extraction hole 54.
[0089] The extraction hole 54 is formed such that the wet tissue 7
separates at the separating portion 10 provided in the wet tissue
continuing material body 6 and the following front end 6a of the
wet tissue continuing material body 6 is allowed to pop up. As
illustrated in FIG. 12B, the extraction hole 54 is opened to the
base plate 52. The extraction hole 54 is formed so that the user
pinches the front end 6a of the wet tissue continuing material body
6 to draw out the front end 6a and the front end 6a of the wet
tissue continuing material body 6 is maintained in the pop-up
state.
[0090] As illustrated in FIG. 12B, the extraction hole 54 is formed
inside an area surrounded by the vertical wall portion 59 and is
opened by breaking the fragile portion 56 and removing the closing
portion 55. The extraction hole 54 is formed to allow the
accommodation space 53 to communicate with the internal space of
the bag body 3 so that the front end 6a of the wet tissue
continuing material body 6 accommodated in the bag body 3 is
pinched, the pinched front end 6a is drawn to the outside of the
bag body 3, and furthermore the front end 6a is maintained in the
pop-up state. As illustrated in FIG. 12B, the extraction hole 54
includes a pinching hole 61 which is opened at substantially the
center portion thereof, is formed to be wide in the
forward-rearward direction, and has an elongated hole shape that
widens in the right-left direction, a first extraction slit 62
which extends to the left while drawing an arc line from the
pinching hole 61, and a second extraction slit 63 which extends to
the right while drawing an arc line from the pinching hole 61. The
first and second extraction slits 62 and 63 are opened to extend
from the pinching hole 61 to the left while drawing a curve with
respect to the pinching hole 61 and thereafter extend to the right
while drawing a curve. In this embodiment, the shape of the
extraction hole is the above-described shape, but is not limited
thereto and may be formed in the other shapes. Further, the shape
of the extraction hole may not be symmetrical in the right-left
direction or may not be symmetrical in the forward-rearward
direction.
[0091] The closing portion 55 partitions the bag body 3 into the
inside and the outside by closing the extraction hole 54. The
closing portion 55 is formed inside the vertical wall portion 59.
Further, a tab 60 is integrally formed with the upper portion of
the closing portion 55. The tab 60 is formed in an annular shape
and is formed so that a part of the inner portion thereof is
connected to the closing portion 55.
[0092] The fragile portion 56 is provided in the peripheral edge
portion of the closing portion 55. As illustrated in FIG. 12A, the
fragile portion 56 is formed at the peripheral edge portion of the
closing portion 55 in a groove shape so that a thickness thereof is
thinner than a thickness of the closing portion 55. Further the
fragile portion 56 is formed to be broken by a stress that occurs
due to a predetermined shear force when the shear force is applied.
Here, the "predetermined shear force" is a force having a
conventionally well-known magnitude needed for the shear failure of
the fragile portion 25 provided at the peripheral edge portion of
the partitioning portion 24.
[0093] Next, the operation/working-effect of the wet tissue
packaging unit according to this embodiment when the front end 6a
of the wet tissue continuing material body 6 is extracted therefrom
will be described. Further, in this embodiment, the procedure of
removing the closing portion 55 and the procedure of extracting the
wet tissue 7 by drawing out the front end 6a of the wet tissue
continuing material body 6 after removing the closing portion 55
are the same as those of the first embodiment, and hence the
description thereof will not be repeated.
[0094] As illustrated in FIG. 12B, in the extraction hole forming
member according to this embodiment, the extraction hole 54
includes the pinching hole 61 and the first and second extraction
slits 62 and 63. When pinching the front end 6a of the wet tissue
continuing material body 6, as needed basis, the user causes the
lowest portion of the extraction hole forming member 51 to approach
the upper surface of the wet tissue continuing material body 6 and
pinches the front end 6a through the pinching hole 61 to be drawn
out from the bag body 3. In this case, since the wet tissue
continuing material body 6 is located at a position where the user
easily pinches the front end 6a, the user may easily pinch the
front end 6a of the wet tissue continuing material body 6 to draw
out the front end 6a. Further, since the wet tissue continuing
material body 6 (the wet tissue 7) which is being drawn out is
drawn out while widening in the right-left direction, the wet
tissue continuing material body 6 is drawn out while passing
through the first and second extraction slits 62 and 63 as well as
the pinching hole 61.
[0095] Here, since the first and second extraction slits 62 and 63
are formed while drawing the curves as described above, a
resistance is applied to the wet tissue continuing material body 6
in the forward-rearward and right-left directions when the wet
tissue continuing material body 6 passes through the first and
second extraction slits 62 and 63. The resistance is applied in the
opposite direction to the direction in which the user draws out the
front end 6a of the wet tissue continuing material body 6.
Therefore, when the separating portion 10 of the wet tissue
continuing material body 6 passes through the extraction hole 54,
the wet tissue continuing material body 6 is separated at the
separating portion 10 and the sheet-like wet tissue 7 is
extracted.
[0096] At this time, in the wet tissue continuing material body 6,
the front end 6a pops up to the upper portion of the extraction
hole 54 and thus tries to move downward. However, even in this
case, a resistance is applied to the wet tissue continuing material
body 6 by the pinching hole 61 and the first and second extraction
slits 62 and 63. The resistance in this case is applied in the
opposite direction to the direction in which the front end 6a of
the wet tissue continuing material body 6 tries to move downward,
and the magnitude of the force balances with the force applied when
the front end 6a tries to move. Therefore, the front end 6a of the
wet tissue continuing material body 6 does not move downward due to
the extraction hole 54 and is maintained in the state of popping up
to the upper portion of the extraction hole 54, that is, in the
pop-up state. At this time, the front end 6a is accommodated in the
accommodation space 53. When the user closes the lid 5, the
accommodation space 53 is sealed and hence the wet state of the wet
tissue continuing material body 6 accommodated in the accommodation
space 53 and the bag body 3 is maintained.
[0097] As described above, according to the wet tissue packaging
unit according to this embodiment, since the extraction hole 54 is
provided in the extraction hole forming member 51 and the pinching
hole 61 and the first and second extraction slits 62 and 63 are
provided in the extraction hole 51, it is possible to easily
extract the wet tissue 7 without complicating the shape of the
extraction hole forming member 51. Further, according to the wet
tissue packaging unit according to this embodiment, since the lid 5
is provided in the extraction hole forming member 51, even when the
volume of the wet tissue continuing material body 6 decreases, the
bag body 3 may be sealed only by closing the lid 5. Therefore, it
is possible to maintain the wet tissue continuing material body 6
accommodated in the bag body 3 in a wet state and thus it is
possible to provide the wet tissue 7 in a state where the chemical
solution and the like are always impregnated therein for the
user.
[0098] Furthermore, according to the wet tissue packaging unit
according to this embodiment, in the case where the wet tissue
packaging unit is the unused item, the extraction hole 54 is closed
by the closing portion 55. To use the wet tissue packaging unit,
the fragile portion 56 provided in the peripheral edge portion of
the closing portion 55 is broken to remove the closing portion 55
and to open the extraction hole 54, and thereafter the front end 6a
of the wet tissue continuing material body 6 is pinched.
Accordingly, it is possible to very easily determine whether or not
the wet tissue packaging unit is the unused item according to the
presence or absence of the extraction hole 54. Therefore, it is
possible for the user to use the wet tissue packaging unit and to
purchase the wet tissue packaging unit after determining whether or
not the wet tissue packaging unit is the unused item.
[0099] Furthermore, according to the wet tissue packaging unit
according to this embodiment, since the extraction hole forming
member 51 provided with the lid 5 is attached to the inner surface
of the bag body 3, during the manufacture, it is possible to
manufacture the wet tissue packaging unit without a process of
attaching the lid 5 after attaching the extraction hole forming
member 51 to the bag body 3. Therefore, according to the wet tissue
packaging unit according to this embodiment, the number of
processes may be reduced during the manufacture and hence it is
possible to largely reduce the manufacturing cost.
[0100] Next, a wet tissue packaging unit according to a third
embodiment of the present invention will be described with
reference to FIGS. 13A to 15C. Further, the description of the same
components as those of the first or second embodiment will not be
repeated and the same reference numerals are used in the
description of the third embodiment.
[0101] The wet tissue packaging unit according to this embodiment
is different from those of the first and second embodiments
described above in the structure of an extraction hole forming
member 71, and hence the structure of the extraction hole forming
member 71 will now be described.
[0102] The extraction hole forming member 71 according to this
embodiment is attached at a position where the positions of an
extraction hole 77 to be described later and the opening 2 of the
bag body 3 coincide with each other on the inner side of the bag
body 3. As a method of attaching the extraction hole forming member
71 to the bag body 3, for example, a method using hot-melt or the
like may be exemplified, but the present invention is not limited
thereto. That is, various methods may be arbitrarily selected.
[0103] As illustrated in FIG. 13A, the extraction hole forming
member 71 includes a base plate 72 as a base portion for attaching
the extraction hole forming member 71 to the bag body 3, an
accommodation space 74 which accommodates the front end 6a of the
wet tissue continuing material body 6 through a pinching hole 73
for extracting the wet tissue 7 to the outside of the bag body 3,
and an extraction hole forming portion 78 having an extraction hole
77 which is opened to separate the wet tissue 7 at the separating
portion 10 of the wet tissue continuing material body 6. Further,
the extraction hole forming member 71 illustrated in this example
includes a partitioning portion which is provided to close the
pinching hole 73 and partitions the accommodation space 74 into a
plurality of sections, and a fragile portion which is formed at the
peripheral edge portion of the partitioning portion and is broken
when a predetermined shear force is applied thereto. In addition,
the configurations of the base plate 72, the pinching hole 73, the
accommodation space 74, the partitioning portion, and the fragile
portion in this embodiment are the same as those of the first
embodiment described above, and hence the detailed description
thereof will not be repeated.
[0104] As illustrated in FIGS. 13A to 14B, in the wet tissue
packaging unit according to this embodiment, the extraction hole
forming portion 78 is supported by the base plate 72 as the base
portion in a cantilevered manner. The extraction hole forming
portion 78 separates the wet tissue 7 at the separating portion 10
provided in the wet tissue continuing material body 6 and allows
the front end 6a of the wet tissue continuing material body 6 to
pop up. The extraction hole forming portion 78 has a leg portion 79
at the front end, and the leg portion 79 is integrally formed with
the base plate 72 on the lower side of the base plate 72 and is
hence integrally formed with the base plate 72. That is, the
extraction hole forming portion 78 is supported by the base plate
72 in a cantilevered manner through the leg portion 79. The
extraction hole forming portion 78 is disposed on the lower side of
the base plate 72 so that the extraction hole 77 is located below a
point where the extraction concave portion of the base plate 72 is
formed. Furthermore, the extraction hole forming portion 78 is
formed in a curved shape.
[0105] As illustrated in FIG. 14B, in the extraction hole forming
portion 78, the extraction hole 77 is opened to the substantially
center portion of the extraction hole forming portion 78 in the
forward-rearward direction. The extraction hole 77 is formed in an
elongated hole shape that extends in the right-left direction. The
extraction hole 77 is formed in a size in which, when the front end
6a of the wet tissue continuing material body 6 or the like passes
therethrough, a resistance is applied to the front end 6a of the
wet tissue continuing material body 6 that passes therethrough.
Further, in the extraction hole forming portion 78, a first slit 80
and a second slit 81 are respectively provided in both ends of the
extraction hole 77 in the forward-rearward direction with respect
to the extraction hole 77. The first and second slits 80 and 81 are
formed in elongated hole shapes that extend in the right-left
direction, and the widths thereof in the forward-rearward direction
are smaller than that of the extraction hole 77 in the
forward-rearward direction. Furthermore, the first and second slits
80 and 81 are formed so that the widths of the first and second
slits 80 and 81 are the same. The first and second slits 80 and 81
are formed so that, when the front end 6a of the wet tissue
continuing material body 6 passes therethrough, a resistance is
applied to the front end 6a of the wet tissue continuing material
body 6 that passes therethrough.
[0106] Furthermore, in the extraction hole forming portion 78, a
first protruding piece 82 is provided between the extraction hole
77 and the first slit 80, and a second protruding piece 83 is
provided between the first slit 80 and the second slit 81. The
first protruding piece 82 includes a left protruding piece 82a that
extends from the left to the right and a right protruding piece 82b
that extends from the right to the left, and a first void 84 is
provided between the left protruding piece 82a and the right
protruding piece 82b. Further, the second protruding piece 83
includes a left protruding piece 83a that extends from the left to
the right and a right protruding piece 83b that extends from the
right to the left, and a second void 85 is provided between the
left protruding piece 83a and the right protruding piece 83b. The
first and second voids 84 and 85 are formed to be located on the
substantially straight line in the right-left direction.
[0107] As illustrated in FIGS. 13A to 14B, the extraction hole
forming member 71 is provided with a relief portion 86. The relief
portion 86 allows a portion of the front end 6a which is not
accommodated in the accommodation space 74 to be relieved into the
bag body 3 when the front end 6a of the wet tissue continuing
material body 6 is pushed into the accommodation space 74. The
relief portion 86 is formed to be surrounded by the base plate 72,
the extraction hole forming portion 78, and the leg portion 79 to
allow the accommodation space 74 and the internal space of the bag
body 3 to communicate with each other. In addition, in this
embodiment, the relief portion 86 is formed on the left, right, and
rear sides of the extraction hole forming portion 78 where the leg
portion 79 is not formed, but the position where the relief portion
86 is formed may be a position other than the above-described
position. Furthermore, the size of the relief portion 86 may be
arbitrarily selected as long as the front end 6a of the wet tissue
continuing material body 6 may move between the accommodation space
74 and the internal space of the bag body 3. The number of relief
portions may also be arbitrarily selected as long as the extraction
hole forming portion 78 is supported by the base plate 72 in a
cantilevered manner.
[0108] Next, the operation of the wet tissue packaging unit
according to this embodiment will be described. As illustrated in
FIG. 15A, the extraction hole forming member 71 according to this
embodiment is formed so that the leg portion 79 provided on the
front side of the extraction hole forming portion 78 is formed
integrally with the lower side of the base plate 72 and the rear
side of the extraction hole forming portion 78 becomes a free end.
Here, in a case that the user pinches and raises the front end 6a
of the wet tissue continuing material body 6 in the H direction
illustrated in FIG. 15B, the extraction hole forming portion 78 is
elastically deformed in the I direction about or on the leg portion
79 as the fulcrum at a side of the free end thereof by a force,
which is applied in the H direction to the extraction hole 77 and
the like when the wet tissue continuing material body 6 is
raised.
[0109] At this time, the relief portion 86 is narrowed.
Subsequently, after extracting the wet tissue 7, when the user
pushes down the front end in the J direction illustrated in FIG.
13C in order to cause the front end 6a of the wet tissue continuing
material body 6 to be accommodated in the accommodation space 74,
the free end is elastically deformed in the K direction about the
leg portion 79 as the fulcrum by a force, which is applied to the
extraction hole 77 and the like when the front end 6a is moved in
the J direction. Hence the free end is turned toward the internal
space of the bag body 2. Accordingly, the relief portion 86 is
widened.
[0110] As described above, according to the wet tissue packaging
unit according to this embodiment, in addition to the effects of
the wet tissue packaging unit 1 according to the first embodiment
described above, since the extraction hole forming portion 78 is
elastically deformed about or on the leg portion 79 as the fulcrum,
ease of extraction when the front end 6a of the wet tissue
continuing material body 6 is extracted is largely improved.
[0111] Further the extraction hole forming portion 78 is
elastically deformed about or on the leg portion 79 as the fulcrum
and is turned when the front end 6a of the wet tissue continuing
material body 6 is accommodated in the accommodation space 74,
thereby widening the accommodation space 74. Therefore, according
to the wet tissue packaging unit according to this embodiment, it
is possible to largely improve ease of extraction of the wet tissue
and ease of accommodation. At this time, it is possible to widen
the relief portion 86 as well as the accommodation space 74.
Therefore, according to the wet tissue packaging unit according to
this embodiment, it is possible to further improve ease of
accommodation of the wet tissue.
[0112] Next, a fourth embodiment of the wet tissue packaging unit
according to the present invention will be described with reference
to FIGS. 16A to 17C. Further, the description of the same
components as those of the first to third embodiments will not be
repeated and the same reference numerals are used in the
description of the fourth embodiment.
[0113] The wet tissue packaging unit according to this embodiment
is different from those of the first to third embodiments described
above in the structure of an extraction hole forming member 91, and
hence the structure of the extraction hole forming member 91 will
now be described.
[0114] The extraction hole forming member 91 according to this
embodiment is disposed or attached at a position where the
positions of an extraction hole 111 and the opening 2 of the bag
body 3 coincide with each other on the inner side of the bag body
3. As a method of attaching the extraction hole forming member 91
to the bag body 3, for example, a method using hot-melt or the like
may be exemplified, but the present invention is not limited
thereto. That is, various methods may be arbitrarily selected.
[0115] As illustrated in FIG. 16A, the extraction hole forming
member 91 includes a base plate 92 as a base portion for attaching
the extraction hole forming member 91 to the bag body 3, an
accommodation space 94 which accommodates the front end 6a of the
wet tissue continuing material body 6 through a pinching hole 93
for extracting the wet tissue 7 to the outside of the bag body 3,
and an extraction hole forming portion 96 having an extraction hole
111 which is opened to separate the wet tissue 7 at the separating
portion 10 of the wet tissue continuing material body 6. Further,
the extraction hole forming member 91 illustrated in this example
includes a partitioning portion which is provided to close the
pinching hole 93 and partitions the accommodation space 94 into a
plurality of sections, and a fragile portion which is formed at the
peripheral edge portion of the partitioning portion and is broken
when a predetermined shear force is applied thereto. In addition,
the configurations of the base plate 92, the pinching hole 93, the
accommodation space 94, the partitioning portion, and the fragile
portion in this embodiment are the same as those of the first
embodiment described above, and hence the detailed description
thereof will not be repeated.
[0116] As illustrated in FIG. 16B, in the wet tissue packaging unit
according to this embodiment, the extraction hole forming portion
is divided into a plurality of portions (in the case of this
embodiment, the extraction hole forming portion 96 is formed by a
first extraction hole forming portion 97 and a second extraction
hole forming portion 98) and is supported by a base plate as the
base portion in a cantilevered manner so that the respective free
ends of the extraction hole forming portions oppose each other. In
this embodiment, a state where the extraction hole forming portion
96 is formed by the two portions including the first extraction
hole forming portion 97 and the second extraction hole forming
portion 98 is used for the description, but the extraction hole
forming portion 96 may include two or more portions.
[0117] The extraction hole forming portion 96 separates the wet
tissue 7 at the separating portion 10 provided in the wet tissue
continuing material body 6 and allows the front end 6a of the wet
tissue continuing material body 6 to pop up. The first extraction
hole forming portion 97 has a leg portion 101a at the front end,
and the leg portion 101a is integrally formed with the base plate
92 on the lower side of the base plate 92 and is hence integrally
formed with the base plate 92. That is, the first extraction hole
forming portion 97 is supported by the base plate 92 in a
cantilevered manner through the leg portion 101a. The second
extraction hole forming portion 98 has a leg portion 101b at the
rear end, and the leg portion 101b is integrally formed with the
base plate 92 on the lower side of the base plate 92 and is hence
integrally formed with the base plate 92. That is, the second
extraction hole forming portion 98 is supported by the base plate
92 in a cantilevered manner through the leg portion 101b.
[0118] As illustrated in FIG. 16B, the first extraction hole
forming portion 97 is provided with a first extraction hole forming
portion concave portion 102 at the rear of the extraction hole
forming portion 96. On the front side of the first extraction hole
forming portion concave portion 102, a first slit 103 and a second
slit 104 are formed. The first and second slits 103 and 104 are
formed in elongated hole shapes that extend in the right-left
direction, and the widths thereof in the forward-rearward direction
are substantially the same as the width of the first extraction
hole forming portion concave portion 102. Furthermore, the first
and second slits 103 and 104 are formed so that the widths of the
first and second slits 103 and 104 are the same. The first and
second slits 103 and 104 are also formed so that, when the front
end 6a of the wet tissue continuing material body 6 passes
therethrough, a resistance is applied to the front end 6a of the
wet tissue continuing material body 6 that passes therethrough.
[0119] Furthermore, in the first extraction hole forming portion
97, a first protruding piece 105 is provided between the first
extraction hole forming portion concave portion 102 and the first
slit 103, and a second protruding piece 106 is provided between the
first slit 103 and the second slit 104. The first protruding piece
105 includes a left protruding piece 105a that extends from the
left to the right and a right protruding piece 105b that extends
from the right to the left, and a first void 107 is provided
between the left protruding piece 105a and the right protruding
piece 105b. Further, the second protruding piece 106 includes a
left protruding piece 106a that extends from the left to the right
and a right protruding piece 106b that extends from the right to
the left, and a second void 108 is provided between the left
protruding piece 106a and the right protruding piece 106b. The
first and second voids 107 and 108 are formed to be located on the
substantially straight line in the right-left direction.
[0120] The second extraction hole forming member 91 is provided
with a second extraction hole forming concave portion 109 on the
front side of the extraction hole forming portion 96. In addition,
the first and second slits 103 and 104 are formed on the rear side
of the first extraction hole forming portion concave portion 102.
The configurations of the first and second slits 103 and 104, the
first and second protruding pieces 105 and 106, and the first and
second voids 107 and 108 are the same as those of the first
extraction hole forming portion 97, and hence the description
thereof will not be repeated.
[0121] The first and second extraction hole forming portions 97 and
98 are formed at the lower surface of the base plate 92 so that the
free ends thereof on the opposite sides to the leg portions 101a
and 101b oppose each other. That is, a free end 101c of the first
extraction hole forming portion 97 is formed to be positioned on
the rear side in relation to the leg portion 101a, and a free end
101d of the second extraction hole forming portion 98 is formed to
be positioned on the front side in relation to the leg portion
101b. A third void 110 is provided between the free end 101c of the
first extraction hole forming portion 97 and the free end 101d of
the second extraction hole forming portion 98 so that the free end
101c of the first extraction hole forming portion 97 and the free
end 101d of the second extraction hole forming portion 98 do not
come into contact with each other when the first and second
extraction hole forming portions 97 and 98 are elastically
deformed. Further, the first and second extraction hole forming
portions 97 and 98 are disposed so that the first and second
extraction hole forming portion concave portions 102 and 109 oppose
each other. As described above, the space formed by the first and
second extraction hole forming portion concave portions 102 and 109
becomes the extraction hole 111. That is, it can be said that the
extraction hole 111 in this embodiment is a hole having an
elongated hole shape that extends in the right-left direction, and
the third void 110 is formed on each of both ends in the right-left
direction. In this embodiment, the third void 110 is provided at
substantially the center portion of the extraction hole forming
member 91 in the forward-rearward direction, but the position where
the third void 110 is provided is not limited thereto.
[0122] As illustrated in FIGS. 16A to 17C, a relief portion 112 is
provided in the extraction hole forming member 91. The relief
portion 112 allows a portion of the front end 6a of the wet tissue
continuing material body 6 which is not accommodated in the
accommodation space 94 to be relieved into the bag body 3 when the
front end 6a is pushed into the accommodation space 94. The relief
portion 112 is formed to be surrounded by the base plate 92, the
leg portion 101a, the first and second extraction hole forming
portions 97 and 98, and the leg portion 101b to allow the
accommodation space 94 and the internal space of the bag body 3 to
communicate with each other. In addition, in this embodiment, the
relief portion 112 is formed on the left and right sides of the
first and second extraction hole forming portions 97 and 98 where
the leg portions 101a and 101b are not formed, but the position
where the relief portion 112 is formed may be a position other than
the above-described position. Furthermore, the size of the relief
portion 112 may be arbitrarily selected as long as the front end 6a
of the wet tissue continuing material body 6 may move between the
accommodation space 94 and the internal space of the bag body 3.
The number of relief portions 112 may also be arbitrarily selected
as long as the extraction hole forming portion 96 is supported by
the base plate 92 in a cantilevered manner.
[0123] Next, the operation of the wet tissue packaging unit
according to this embodiment will be described. As illustrated in
FIG. 17A, the extraction hole forming portion 96 according to this
embodiment is formed by the first and second extraction hole
forming portions 97 and 98. The first extraction hole forming
portion 97 is formed so that the leg portion 101a provided on the
front side of the first extraction hole forming portion 97 is
formed integrally with the lower side of the base plate 92 and the
rear side of the first extraction hole forming portion 97 becomes
the free end 101c. In addition, the second extraction hole forming
portion 98 is formed so that the leg portion 101b provided on the
rear side of the second extraction hole forming portion 98 is
formed integrally with the lower side of the base plate 92 and the
front side of the second extraction hole forming portion 98 becomes
the free end 101d. As described above, the third void 110 is
provided between the free end 101c of the first extraction hole
forming portion 97 and the free end 101d of the second extraction
hole forming portion 98. Furthermore, the extraction hole 111 is
formed by the first extraction hole forming portion concave portion
102 provided in the free end 101c of the first extraction hole
forming portion 97 and the second extraction hole forming portion
concave portion 109 provided in the free end 101d of the second
extraction hole forming portion 98.
[0124] Here, in the case that the user pinches the front end 6a of
the wet tissue continuing material body 6 and raises the front end
6a in the L direction illustrated in FIG. 17B, the first extraction
hole forming portion 97 is elastically deformed in the M direction
about or on the leg portion 101a as the fulcrum at the side of free
end 101c by a force, which is applied in the L direction to the
first extraction hole forming portion concave portion 102 when the
wet tissue continuing material body is raised. In addition, in the
second extraction hole forming portion 98, when the wet tissue is
raised, the free end 101d is elastically deformed in the M
direction about the leg portion 101b as the fulcrum by a force,
which is applied in the L direction to the second extraction hole
forming portion concave portion 109.
[0125] Furthermore, after extracting the wet tissue 7, when the
user pushed down the front end 6a in the N direction illustrated in
FIG. 17C in order to cause the front end 6a of the wet tissue
continuing material body 6 to be accommodated in the accommodation
space 94, the first extraction hole forming portion 97 is
elastically deformed in the O direction about or on the leg portion
101a as the fulcrum at the side of the free end 101c by the force,
which is applied to the first extraction hole forming portion
concave portion 102 and the like when the front end is moved in the
O direction. Similarly, in the second extraction hole forming
portion 98, when the front end 6a is moved in the O direction, the
free end 101d is elastically deformed in the O direction about the
leg portion 101b as the fulcrum by the force, which is applied to
the second extraction hole forming portion concave portion 109 and
the like.
[0126] As described above, according to the wet tissue packaging
unit according to this embodiment, in addition to the effects of
the wet tissue packaging unit 1 according to the first embodiment
described above, since the first extraction hole forming portion 97
is elastically deformed about the leg portion 101a as the fulcrum
and the second extraction hole forming portion 98 is elastically
deformed about the leg portion 101b as the fulcrum, ease of
extraction when the front end 6a of the wet tissue continuing
material body 6 is extracted is largely improved.
[0127] In addition, when the front end 6a of the wet tissue
continuing material body 6 is accommodated in the accommodation
space 94, the first extraction hole forming portion 97 is
elastically deformed about the leg portion 101a as the fulcrum and
the second extraction hole forming portion 98 is elastically
deformed about the leg portion 101b as the fulcrum, thereby
widening the accommodation space 94.
[0128] Therefore, according to the wet tissue packaging unit
according to this embodiment, it is possible to largely improve
ease of extraction of the wet tissue and ease of accommodation.
Furthermore, according to the wet tissue packaging unit according
to this embodiment, when the accommodation space 94 is widened, the
relief portion 112 is also widened as well as the accommodation
space 94. Therefore, according to the wet tissue packaging unit
according to this embodiment, it is possible to further improve
ease of accommodation of the wet tissue.
[0129] In addition, in the present specification, the example in
which the lid 5 is integrally molded with the extraction hole
forming member 4 through the hinge portion 5a is used for the
description, but the lid 5 may also be molded separately from the
extraction hole forming member 4. In addition, in the case where
the lid 5 and the extraction hole forming member 4 are molded
integrally with each other, the lid 5 and the extraction hole
forming member 4 may be formed through a portion other than the
hinge portion 5a, or may be formed without the hinge portion 5a or
the portion other than the hinge portion 5a interposed
therebetween.
[0130] Further, in the present specification, the fragile portion
is a groove that is thinner than the partitioning portion. However,
when the predetermined shear force is applied to the fragile
portion, the fragile portion may be broken due to stress
concentration on the fragile portion, and a shape other than the
shape of this embodiment may be arbitrarily selected. Further, as a
method of forming the fragile portion, an existing method may be
arbitrarily selected to be applied. For example, the fragile
portion may be formed using ultrasonic waves, or the fragile
portion may be formed through pressurization using a press.
Otherwise, the fragile portion may be formed using a laser, or the
fragile portion may be formed by a method other than the
above-described methods. Furthermore, although the fragile portion
is formed through the integral molding, this embodiment is not
limited to the case of the integral molding.
[0131] Further, in the first, third, and fourth embodiments
according to the present invention, the first and second slits are
provided and the first and second protruding pieces are provided in
the extraction hole forming portion, and in the second embodiment,
the first and second extraction slits are provided in the
extraction hole forming portion. However, these are merely examples
and may be appropriately changed without departing from the spirit
of the present invention. Further, the sizes of the first and
second slits, the first and second protruding pieces, and the
extraction hole formed in the first, third, and fourth embodiments
may be arbitrarily selected as long as the front end of the wet
tissue continuing material body may be extracted and the front end
may pop up. Furthermore, the sizes of the extraction hole, the
first and second extraction slits formed in the second embodiment
may be arbitrarily selected as long as the front end of the wet
tissue continuing material body may be extracted and the front end
may pop up.
[0132] In the present specification, the example in which the
extraction hole forming portion and the base plate are integrally
formed with each other is used for the description. However, the
present specification is not limited thereto, and the extraction
hole forming portion and the base plate may be separately formed
from each other. Further, in the present specification, the
extraction hole forming member is formed to be curved, but the
present specification is not limited thereto.
[0133] The wet tissue packaging unit that has been described so far
is merely an example of the wet tissue packaging unit according to
the present invention, and may be appropriately changed without
departing from the spirit of the present invention.
