Description
TECHNICAL FIELD
[0001] The present invention relates to a wet tissue package that
stores and packages wet tissues in a bag body.
BACKGROUND ART
[0002] Wet tissues are widely used for wiping one's hands or the
buttocks of infants, sick persons, or old persons. A wet tissue is
base fabric such as nonwoven fabric impregnated with a chemical
such as a cleaning liquid, an antiseptic liquid or the like and is
normally stored in a sealed storage container to be able to
maintain a state in which the base fabric is wet with a chemical or
the like. A bottle-type storage container in a cylindrical shape
has widely been used, but a bottle-type wet tissue package stores a
wet tissue wound as a roll vertically in an storage container and
thus, it is difficult to make the container compact, posing a
problem of larger sizes of the storage container and higher
manufacturing costs. In recent years, therefore, instead of the
bottle-type wet tissue package, a bag-type wet tissue package
enabling one to take out one folded wet tissue at a time by storing
and packaging folded wet tissues in a bag body is increasingly
used.
[0003] As a bag-type wet tissue package, a wet tissue package
configured such that a wet tissue drawing hole forming member or an
outlet member formed a wet tissue drawing hole at the bottom
portion is mounted on the inner side around a bag body opening
formed from a film having airtightness or the like and a wet tissue
inside the packing body is taken out from the bag body opening
through the wet tissue drawing hole is widely used (see, Patent
Literature 1).
[0004] As a wet tissue package of the related art, a package has
been widely used which seals an opening of a bag body by a
sheet-like cover in an openable and closable manner (see Patent
Document 2).

SUMMARY OF INVENTION
Technical Problem
[0007] Wet tissues stored inside the bag-type wet tissue package in
a folded state can be taken out one wet tissue after another by
tearing along the perforation or the like. The opening of the bag
body is sealed with a cover such as a cover unit member or an
airtight film and the method of folding wet tissues and the shape
of the drawing hole are devised such that when the cover is
unsealed and a wet tissue is pulled to take out the wet tissue, the
tip portion of the next wet tissue is protruded from the drawing
hole. If a wet tissue with the tip portion thereof protruded from
the wet tissue drawing hole is left alone, the wet tissue is dried
and it is necessary to seal the opening of the bag body again if
there is some time before the wet tissue is used next time and the
tip portion of the wet tissue protruding from the drawing hole is
stored in a space between the drawing hole and the opening of the
bag body. However, a conventional bag-type wet tissue package has
only a narrow space formed between the wet tissue drawing hole and
the opening of the bag body and thus, even if an attempt is made to
seal the opening of the bag body with the cover, it is difficult to
reliably seal and store the tip portion of the wet tissue
protruding from the drawing hole in the space between the drawing
hole and the opening of the bag body. Particularly if the remaining
amount of wet tissue in the bag body decreases, the volume of the
tip portion of the wet tissue protruding after being pulled out
from the drawing hole increases. Thus, it becomes difficult to seal
and store the tip portion protruding from the drawing hole reliably
in the storage space. In addition, there is a problem of an
increased size of the whole packing body if the volume of the
storage space is increased by increasing the depth from the opening
of the bag body to the bottom portion of the outlet member and also
a problem that if an attempt is made to retain the size of the
packing body, it is unavoidable to reduce the amount of wet tissue
stored in the bag body. Further, a package of which an opening of a
bag body is sealed by a sheet-like cover is provided at low cost.
However, the periphery of the opening of the bag body is wrinkled
when the opening of the bag body is sealed again by the cover, and
hence it is difficult to stick the cover to the periphery of the
opening in a close contact state. As a result, a problem arises in
that the opening of the bag body may not be reliably sealed
again.
[0008] The present invention is made to solve such problems of the
related art, and an object thereof is to provide a bag type wet
tissue package that stores a front end of a wet tissue popping out
from an drawing hole in a space between the drawing hole and an
opening of a bag body and reliably seals the opening of the bag
body by a sheet-like cover again.
Solution to Problem
[0009] Namely, the gist of the present invention is
[0010] (1) A wet tissue package that seals an opening of an
air-tight bag body storing a wet tissue by a sheet-like cover in an
openable and closable manner, wherein a outlet member formed a wet
tissue drawing hole and facing flange portions is attached to the
inside of the periphery of the opening of the bag body by sticking
the flange portions to the bag body, a space of a concave portion
between the opening of the bag body and the outlet member is formed
so that its plane cross section is larger than the opening area of
the opening of the bag body, and a sheet-like cover is stuck to the
bag body so that a periphery of an edge of a portion serving as a
hinge portion used for an operation of opening and closing the
sheet-like cover and a periphery of an opening side edge are
respectively located at positions partially overlapping at least
the facing flange portions of the outlet member, thereby sealing
the opening of the bag body.
[0011] (2) the wet tissue package according to (1) above, wherein
at least a portion of the side wall of the outlet member has a
shape of communicating through the bag body,
[0012] (3) the wet tissue package according to (1) above, wherein
the outlet member is mounted in a recessed position on the inner
side from an edge of the opening of the bag body,
[0013] (4) the wet tissue package according to (2) above, wherein
the outlet member is mounted around the opening of an inner surface
of the bag body via the flange portion formed by overhanging from
the edge of the upper end portion of the outlet member to an outer
side,
[0014] (5) the wet tissue package according to (1) above, wherein
the outlet member is configured by processing and forming the wet
tissue drawing hole and the flange portion in a plate body.
Advantageous Effects of Invention
[0015] A plane cross section of a concave space of a outlet member
is formed larger than an opening area of an opening of a bag body
in a wet tissue package in the present embodiment; therefore, the
volume of the concave space is large and drying of a wet tissue can
be prevented by reliably sealing and storing a tip portion of the
wet tissue protruding from an drawing hole in the concave space.
Further, there is no need to worry about a problem in which the
cover is stuck to the opening in an incomplete contact state due to
the wrinkle formed in the periphery of the opening of the bag body
when the opening of the bag body is sealed again by the cover. For
this reason, since the package may be reliably sealed again, it is
possible to prevent the wet tissue from being dried.

DESCRIPTION OF EMBODIMENT
[0026] FIG. 1 shows an outside configuration of a wet tissue
package 1 of the present invention and reference numeral 2 is a bag
body, reference numeral 3 is an opening of the bag body 2, a
reference numeral 4 is a cover. FIG. 1A shows a state in which the
opening 3 of the bag body 2 is sealed with the cover 4 made of an
airtight film or sheet and FIG. 1B shows a state in which the
opening 3 is unsealed by opening the cover 4. As shown in FIG. 2,
folded wet tissues 5 are stored inside the bag body 2.
[0027] The bag body 2 is formed in a bag shape such as a pillow
shape as shown, for example, in FIGS. 1A and 1B by sealing ends of
the plastic sheet or film having airtightness with a heat seal or
the like. The bag body 2 is made of an airtight material and is
formed of, as shown, for example, in FIG. 2, a 2-layer layered
product of an inner layer 2a and an outer layer 2b. A layered
product of one or two or more of, for example, polyethylene,
polypropylene, polyester, polyamide, vinyl chloride, vinylidene
chloride, and cellophane or a complex obtained by further stacking
aluminum foil is used as the inner layer 2a, and polyethylene
terephthalate (PET) or the like is used as the outer layer 2b. In
the present embodiment, the bag body 2 is formed of the two layers
of the inner layer 2a and the outer layer 2b, but is not limited to
such an example and may be formed of multiple layers of three
layers or more, or one layer. In addition, materials used for the
inner layer 2a and the outer layer 2b are not limited to the above
materials.
[0028] The wet tissues 5 are ground fabric such as nonwoven fabric
impregnated with a chemical such as a cleaning agent, an
antibacterial or the like and are stored in the bag body 2 after
being folded. The wet tissues 5 are folded and stored such that the
wet tissues can be taken out one by one.
[0029] An outlet member formed a wet tissue drawing hole 6 is
mounted on the inner side of a periphery of the opening 3 of the
bag body 2. The outlet member 6 is made of paper, synthetic resin,
metal or the like and is formed from, for example, a punched molded
body of paper, a synthetic resin sheet or film, a thermal molded
body of a thermoplastic resin sheet or film, an injection molded
body of thermoplastic resin or the like. The outlet member 6 is
formed in a box shape having a concave space 7 as shown, for
example, in FIG. 3 and a flange portion 6a formed by overhanging to
the inner side of the edge of the upper end portion is fixed to and
mounted on the periphery of the opening 3 of the bag body 2. A wet
tissue drawing hole through which the wet tissue 5 in the bag body
2 is taken out is provided at the bottom portion of the outlet
member 6. The outlet member 6 is fixed by sticking the flange
portion 6a to the bag body 2 by an emulsion adhesive, a hot-melt
adhesive, a heat-seal, or the like, but the present invention is
not limited to the case where the entire surface of the flange
portion 6a is stuck to the bag body 2. For example, a part of the
surface of the flange portion may be stuck to the bag body at some
spots. The concave space 7 of the outlet member 6 is a space in
which a tip portion 5a of the wet tissue 5 to be taken out next is
stored and the wet tissue package 1 in the present invention has
the outlet member 6 formed such that the plane cross section of the
concave space 7 is larger than the opening area of the opening 3 of
the bag body 2 to allow the tip portion 5a of the wet tissue
protruding from the wet tissue drawing hole 8 to be sealed and
stored reliably in the concave space 7. In the outlet member 6
illustrated in FIG. 3, the flange portion 6a provided to mount the
outlet member 6 to the peripheral edge of the opening 3 of the bag
body 2 is formed on four sides of the outlet member 6 so as to
protrude inward from the peripheral edge of the upper end of the
outlet member 6, and the plane cross section of the concave space 7
is larger than the opening area of the opening 3.
[0030] The wet tissue drawing hole 8 is configured such that the
wet tissue 5 stored in the packing body 2 is taken out one by one
and, as shown, for example, in FIG. 4, a picking portion 8a and a
pulling portion 8b whose opening area is smaller than that of the
picking portion 8a are linked via a tapering portion 9 of the
picking portion 8a. The pulling portion 8b is provided with a
protrusion 10 to apply a load to the wet tissue to be pulled out
and a slit 11 to allow the wet tissue to be taken out easily one
wet tissue after another by providing an elastic force to the load
applied to the wet tissue by the protrusion 10. The wet tissue
drawing hole 8 is not limited to the shape shown in FIG. 4, and any
shape allowing the wet tissue 5 to be taken out one by one may be
adopted and various shapes shown in, for example, FIGS. 5A to 5H
may be adopted.
[0031] When the user uses the wet tissue package 1 for the first
time, the tip portion 5a of the wet tissue 5 does not protrude into
the concave portion 7 after the cover 4 being unsealed. Thus, as
shown in FIG. 6, the user picks and pulls up the wet tissue 5 in
the packing body 1 from the picking portion 8a. At this point, with
a folding line 12 of the folded wet tissue 5 being stored inside
the bag body 2 so as to be in a direction perpendicular to the
direction connecting the picking portion 8a and the pulling portion
8b of the drawing hole 8 (direction along an arrow in FIG. 4), the
wet tissue 5 moves in the direction of an arrow A in FIG. 6 and
moves from the picking portion 8a to the pulling portion 8b via the
tapering portion 9 while being pulled up. At this point, a load is
applied to the wet tissue by the tapering portion 9 and the
protrusion 10 and if the wet tissue is further pulled up, a first
wet tissue and a second wet tissue are separated while the tip
portion 5a of the second wet tissue protrudes from the pulling
portion 8b. Then, when the second or subsequent wet tissue is
pulled out, the tip portion 5a of the wet tissue protrudes from the
pulling portion 8b and so the protruding tip portion 5a can be
picked and pulled up to take out the second wet tissue and because
a load is applied to the wet tissue 5 by the protrusion 10 of the
pulling portion 8b, the second and third wet tissues are separated
while the tip portion 5a of the third wet tissue protrudes from the
pulling portion 5b.
[0032] When the wet tissue 5 is not further taken out, drying of
the remaining wet tissue can be prevented by storing the tip
portion 5a inside the concave space 7 and sealing the opening 3 of
the bag body 2 with the cover 4. The packing body 1 in the present
invention is formed such that the plane cross section of the
concave space 7 is larger than the opening area of the opening 3
and the volume of the concave space 7 and thus, when the remaining
amount of the wet tissue 5 in the bag body 2 is small or even when
the amount of protrusion of the tip portion 5a of the next wet
tissue protruding from the wet tissue drawing hole 8 because the
pull-up force when a wet tissue is pulled out is too strong, drying
can be prevented by reliably storing and sealing the protruding tip
portion 5a inside the concave space 7.
[0033] In the opening 3 of the bag body 2 of the wet tissue package
1 of the present invention, the opening 3 is sealed by sticking the
sheet-like cover 4 to the periphery of the opening 3 through an
adhesive layer so that the opening 3 may be repeatedly sealed and
opened. In the sheet-like cover 4, the sticking position in the
periphery of the edge of the portion serving as the hinge portion
4a used for the operation of opening and closing the cover 4
becomes a position that partially overlaps at least the attachment
position of the flange portion 6a of the outlet member 6 with
respect to the bag body 2. Furthermore, the cover 4 is stuck to the
bag body 2 so that the peripheral position of the opening side edge
4b of the cover becomes a position partially overlapping at least
the position of the flange portion 6a facing the flange portion 6a
(the flange portion 6a overlapping the sticking position of the
periphery of the edge of the portion serving as the hinge portion
4a of the cover 4) in the outlet member 6. The sheet-like cover 4
seals the opening 3 while being stuck to the bag body 2 so that the
attachment position of the periphery of the edge of the portion
serving as the hinge portion 4a used for the opening and closing
operation and the position of the periphery of the opening side
edge 4b of the cover 4 are respectively located at positions
partially overlapping at least the positions where the facing
flange portions 6a of the outlet member are stuck to the bag body.
Accordingly, since the peripheral edge of the bag body the opening
3 is not wrinkled when the opening 3 of the bag body is sealed
again by the cover 4 after the opening operation and the cover 4
may be stuck to the peripheral edge of the opening 3 in a close
contact state, the package may be reliably sealed again. As the
adhesive for sticking the cover 4 in an openable and closable
manner, for example, an adhesive mainly containing an acrylic
fabric size, polyvinyl chloride composition containing plasticity,
craft copolymer in which an ethylene-vinyl acetate copolymer is
craft-polymerized with an vinyl chloride monomer or the like can be
cited, but is not limited to the above examples if the adhesive is
capable of repeatedly paste and separate the cover 4. The cover 4
is formed by a sheet or a film that is single, or multiply
laminated layers with two or more such sheets of a synthetic resin
having air-tightness like the bag body 2. When the cover is formed
in a size in which the sticking position of the periphery of the
edge of the portion serving as the hinge portion 4a and the
position in the periphery of the opening side edge 4b partially
overlap at least the facing flange portions 6a and 6a of the outlet
member 6, the length of the cover may be slightly larger or smaller
than the length of the outlet member 6 (the length from the edge of
the flange portion 6a to the edges of the facing flange portions
6a). However, it is desirable that the length of the cover is
substantially equal to the length of the outlet member 6 as
illustrated in the drawings.
[0034] In the wet tissue package 1 of the present invention, the
outlet member 6 is not limited to the shape shown in FIG. 3 and any
shape capable of making the plane cross section of the concave
space 7 larger than the opening area of the opening 3 of the bag
body may be adopted and, as shown in FIG. 7, a shape in which a
communicating portion 13 communicating through the bag body 2 in at
least a portion of a side wall 6b may be adopted. If the
communicating portion 13 is provided, the space inside the bag body
2 can also be used as the concave space 7 to accommodate the tip
portion 5a of the wet tissue 5 and so the size of the outlet member
6 can be made smaller. In the example shown in FIG. 7, while the
communicating portion 13 is provided only on the opposing two sides
of the side walls 6b of four sides, the communicating portion 13
may also be provided in the side walls 6b of all the four sides.
When the communicating portion 13 is provided in the side wall 6b,
the flange portion 6a is not limited to one formed by overhanging
from the edge of the upper end portion of the outlet member 6 to
the inner side and may be formed by overhanging to the outer side.
Even when the aforementioned flange portion 6a is mounted along the
edge of the opening 3 of the bag body 2 or mounted on the bag body
2, as in a different mode (FIG. 9) described later, in a position
on the inner side from the edge of the opening 3, the plane cross
section of the concave space 7 can be formed larger than the
opening area of the opening 3.
[0035] The outlet member is not limited to this embodiment that has
the flange portion 6a provided at each of four sides thereof, and
the flange portion 6a may be provided only in a pair of facing
edges as illustrated in FIGS. 8A to 8C. The outlet member 6
illustrated in FIGS. 8A to 8C is formed so that at least a part of
the side wall communicates through the bag body 2. While the outlet
member 6 in the shapes shown in FIGS. 3 and 7 is normally
manufactured by injection molding, the outlet member 6 as shown in
FIGS. 8A, 8B, or 8C can be manufactured by a simple method such as
stamping the drawing hole 8 in a plate body of synthetic resin and
then pressing the plate body into a right-angle shape or a curved
shape, or stamping the drawing hole 8 in a long molded body formed
by extrusion and cutting the molded body.
[0036] FIG. 9 shows a different mode of the wet tissue package 1 of
the present invention. The wet tissue package 1 has as the outlet
member 6 a shape in which the flange portion 6a is formed by
overhanging from the edge of the upper end portion of the outlet
member 6 to the outer side, but is formed such that the plane cross
section of the concave space 7 is larger than the opening area of
the opening 3 of the bag body 2 by mounting the flange portion 6a
on the bag body 2 in a recessed position on the inner side from the
edge of the opening 3 of the bag body 2; therefore, a sufficient
volume of the concave space 7 can be secured and the tip portion 5a
of the wet tissue 5 protruding from the wet tissue drawing hole 8
to the concave space 7 can reliably be sealed and stored inside the
concave space 7.
[0037] As a method of folding the wet tissue 5 packaged in the wet
tissue package 1 in the present invention, for example, as shown in
FIG. 10A, the long folded wet tissue 5 provided with a tear-off
portion 14 such as perforation at predetermined intervals, as shown
in FIG. 10B, a plurality of wet tissues 51 folded in a Z shape
called Z folding in which ends thereof are made to mutually
overlap, as shown in FIG. 10C, the plurality of wet tissues 51
folded in a Z shape and a plurality of wet tissues 52 folded in a W
shape called WZ folding in which ends thereof are alternately made
to mutually overlap and the like can be cited, but the method of
folding is not limited to the above examples and various method of
folding like folding combining vertical folding and horizontal
folding can be adopted.
