Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to both Japanese Patent
Application No. 2018-074872 filed on Apr. 9, 2018 and Japanese
Patent Application No. 2018-102734 filed on May 29, 2018. The
foregoing applications are incorporated herein by reference in
their entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0002] The present invention relates to a packaging tool for
packaging an object to be packaged, and a packaging box for housing
the packaging tool therein.
2. Description of the Related Art
[0003] Due to popularization of mail order such as Internet
shopping, a demand for delivery of a relatively small packet to an
individual house rapidly increases. The commercial products to be
delivered are various in shape and size, and some of them change in
shape such as a bag of shampoo. Such various objects to be packaged
are put into boxes, and therefore a packaging tool and a packaging
box enabling efficient packaging and delivery in a stable state are
required.
[0004] As the packaging tool of this kind, there is a known
packaging tool which includes: a mounting part for mounting an
object to be packaged thereon and a plate-like member having a pair
of standing parts provided continuously thereto via bend lines on
both sides of the mounting part respectively; and a heat-shrinkable
thin film member which is cylindrical and into which the plate-like
member is inserted in a manner to cover at least the mounting part,
wherein the plate-like member is deformable from a flat exploded
state into a standing state with the standing parts bent upward.
The mounting part of this packaging tool is formed such that the
length of a middle part parallel to both edge parts along edges of
the plate-like member is larger than the length of the edge parts
in the exploded state, and is curved such that the middle part is
located above both the edge parts in the standing state.
[0005] The mounting part formed of a corrugated cardboard is curved
to be along a concave shape when the standing parts are made to
stand, so that the middle part is located above both the edge
parts. As a result of this, the object to be packaged on the
mounting part is pushed upward, so that the thin film member is
pulled to the upper side via the object to be packaged and becomes
tense for holding the object to be packaged with reaction force
thereto.
[0006] Patent Document 1: Japanese Laid-open Patent Publication No.
2018-2170
SUMMARY OF THE INVENTION
[0007] However, formation of the length of the middle part parallel
to both the edge parts along the edges of the plate-like member
larger than the length of the edge parts brings about a problem of
a work of standing the standing parts becoming necessarily
complicated. Another problem is that the standing parts prevent
rolling of the object to be packaged at the time of packaging but
there is 8 nothing provided in a direction of two sides, of four
sides of the mounting part, where the standing parts are not
formed, so that rolling cannot be prevented. For example, at the
time of packaging a cylindrical product such as a spray can, it can
be considered that it may be necessary to perform the work while
pressing the spray can by one hand. Besides, there may be a case
where a plurality of stacked bags of shampoo collapse. If it is
necessary to pay attention to the cases, those works are also
causes of complication.
[0008] An object of the present invention in consideration of the
above problems is to provide a packaging tool and a packaging box
allowing a packaging work to be performed without careful attention
paid to rolling of an object to be packaged.
[0009] To achieve the above object, the present invention includes
the following features. Note that the definition and the like of
words and terms performed in describing the invention as set forth
in any of claims are assumed to be applied to the inventions as set
forth in other claims regardless of the order of the description.
Further, though the expressions "one" and "another" are used, they
are not intended to specify any one of them but is indicate the
relation that when one is arbitrarily decided, another is decided
in response to that.
(Feature of Invention of Claim 1)
[0010] A packaging tool according to the invention of claim 1
(hereinafter, referred to as a "packaging tool of claim 1")
includes: a mounting part including a rectangular mounting surface
having one pair of opposed sides and another pair of opposed sides,
for mounting an object to be packaged thereon; a pair of one and
another pressing pieces provided to be able to bend and stand
upward via another pair of bend lines, on the another pair of
opposed sides of the mounting surface respectively; and a pair of
one and another coupling pieces which couple opposed side ends of
the one and another pressing pieces to keep a standing state of the
one and another standing pieces, and configured to be able to be
housed in a packaging box with the pressing pieces standing and
coupled by the pair of coupling pieces.
[0011] According to the packaging tool of claim 1, an upper space
of the mounting surface is surrounded by the pair of pressing
pieces and the pair of coupling pieces, so that even when the
object to be packaged mounted on the mounting surface rolls or
collapses, further movement is prevented. Therefore, the packaging
work can be performed without careful attention paid to the rolling
or collapse. In this state, it is possible to cover the mounted
object to be packaged by the heat-shrinkable film, together with
the packaging tool except the pair of standing pieces, and to
effectively prevent rolling and collapse at that time. It is
possible to form, as needed, an adhesive layer for restricting the
movement of the packaging tool, between the bottom surface of the
packaging box for housing the packaging tool therein and the lower
surface of the mounting part.
(Feature of Invention of Claim 2)
[0012] A packaging tool according to the invention of claim 2
(hereinafter, referred to as a "packaging tool of claim 2") is the
packaging tool according to claim 1, further including: a pair of
one and another standing pieces provided to be able to bend and
stand upward via one pair of bend lines, on the one pair of opposed
sides of the mounting part respectively.
[0013] According to the packaging tool of claim 2, at the time of
trying to pull up the packaging tool for transporting it or putting
it into a packaging box, a user can accomplish the purpose only by
grasping the pair of standing pieces by hands. There is a case
where it is hard to pull up the packaging tool when the object to
be packaged is mounted, in particular, the heat-shrinkable film is
covered thereon, but the work can be easily performed by grasping
the standing pieces.
(Feature of Invention of Claim 3)
[0014] A packaging tool according to the invention of claim 3
(hereinafter, referred to as a "packaging tool of claim 3") is a
packaging tool including: a mounting part including a rectangular
mounting surface having one pair of opposed sides and another pair
of opposed sides, for mounting an object to be packaged thereon;
and a pair of one and another standing pieces provided to be able
to bend and stand upward via one pair of bend lines, on the one
pair of opposed sides of the mounting part respectively, and
configured to be able to be housed in a packaging box with the
standing pieces bending and standing upward. The packaging tool
further includes: a pair of one and another pressing pieces
provided to be able to bend and stand upward via another pair of
bend lines, on the another pair of opposed sides of the mounting
surface respectively; and a pair of one and another coupling pieces
which couple opposed side ends of the one and another pressing
pieces to keep a standing state of the one and another standing
pieces.
[0015] According to the packaging tool of claim 3, an upper space
of the mounting surface is surrounded by the pair of pressing
pieces and the pair of coupling pieces, so that even when the
object to be packaged mounted on the mounting surface rolls or
collapses, further movement is prevented. Therefore, the packaging
work can be performed without careful attention paid to the rolling
or collapse. In this state, it is possible to cover the mounted
object to be packaged by the heat-shrinkable film, together with
the packaging tool except the pair of standing pieces, and to
effectively prevent rolling and collapse at that time. Further, at
the time of trying to pull up the packaging tool for transporting
it or putting it into a packaging box, a user can accomplish the
purpose only by grasping the pair of standing pieces by hands.
There is a case where it is hard to pull up the packaging tool when
the object to be packaged is mounted, in particular, the
heat-shrinkable film is covered thereon, but the work can be easily
performed by grasping the standing pieces.
(Feature of Invention of Claim 4)
[0016] A packaging tool according to the invention of claim 4
(hereinafter, referred to as a "packaging tool of claim 4") is the
packaging tool according to any one of claims 1 to 3, wherein: one
trapezoidal part is provided continuously at an upper end of the
one pressing piece, the one trapezoidal part having a lower bottom
of the same length as a length of the upper end of the one pressing
piece and tapering upward; and another trapezoidal part is provided
continuously at an upper end of the another pressing piece, the
another trapezoidal part having a lower bottom of the same length
as a length of the upper end of the another pressing piece and
tapering upward.
[0017] According to the packaging tool of claim 4, the one and
another pressing pieces establish a state of restricting freedom,
namely, a state of surely holding the object to be packaged.
Contrarily, the one and another trapezoidal parts are not
constrained by the pressing pieces and are made to taper, and are
therefore pliable in directions of covering over the object to be
packaged. Though the pliability is not essential, for example, when
the object to be packaged is covered by the heat-shrinkable film,
the object to be packaged can be surely protected and held by the
trapezoidal parts covering over the object to be packaged by the
tension of the heat-shrinkable film. In this event, the tops of the
trapezoidal parts are not sharp, and therefore never stick into and
break the heat-shrinkable film.
(Feature of Invention of Claim 5)
[0018] A packaging tool according to the invention of claim 5
(hereinafter, referred to as a "packaging tool of claim 5") is the
packaging tool according to claim 4, wherein the one coupling piece
includes one and another coupling small pieces configured to be
able to bend in opposed directions via bend lines from the one
pressing piece and the another pressing piece respectively; and the
another coupling piece includes one and another coupling small
pieces configured to be able to bend in opposed directions via bend
lines from the one pressing piece and the another pressing piece
respectively, and the packaging tool further including: one
detachable coupling structure between the one coupling small piece
and the another coupling small piece opposed thereto; and another
detachable coupling structure between the one coupling small piece
and the another coupling small piece opposed thereto.
[0019] According to the packaging tool of claim 5, though not
essential, the whole packaging tool can be composed of a sheet (for
example, corrugated cardboard). In other words, by cutting a sheet
into a predetermined shape and forming necessary bend lines
thereon, it is possible to form the mounting part, the pair of
standing pieces, the pair of pressing pieces, and the pair of
coupling pieces bent up. At each of the pair of coupling pieces,
the one coupling small piece and the another coupling small piece
which are bent up only need to be coupled by the coupling
structure. Since the coupling structure is detachable, by releasing
the coupling after use, the packaging tool can be returned into a
sheet. Discard is easy and reuse becomes possible.
(Feature of Invention of Claim 6)
[0020] A packaging tool according to the invention of claim 6
(hereinafter, referred to as a "packaging tool of claim 6") is the
packaging tool according to claim 5, wherein: an upper end of the
one coupling piece when coupled by the one coupling structure is
formed almost parallel to the mounting surface, and one pair of
trapezoidal parts having a lower bottom of the same length as a
length of the upper end and tapering upward are provided
continuously at the upper end; an upper end of the another coupling
piece when coupled by the another coupling structure is formed
almost parallel to the mounting surface, and another pair of
trapezoidal parts having a lower bottom of the same length as a
length of the upper end of the another coupling piece and tapering
upward are provided continuously at the upper end; the one coupling
structure is formed across the one coupling piece and the one pair
of trapezoidal parts; and the another coupling structure is formed
across the another coupling piece and the another pair of
trapezoidal parts.
[0021] According to the packaging tool of claim 6, the one and
another coupling pieces establish a state of restricting freedom,
namely, a state of surely holding the object to be packaged.
Contrarily, the one and another trapezoidal parts are not
constrained by the coupling pieces and are made to taper, and are
therefore pliable in directions of covering over the object to be
packaged. Though the pliability is not essential, for example, when
the object to be packaged is covered by the heat-shrinkable film,
the object to be packaged can be surely protected and held by the
trapezoidal parts covering over the object to be packaged by the
tension of the heat-shrinkable film. In this event, the tops of the
trapezoidal parts are not sharp, and therefore never stick into and
break the heat-shrinkable film.
(Feature of Invention of Claim 7)
[0022] A packaging tool according to the invention of claim 7
(hereinafter, referred to as a "packaging tool of claim 7") is the
packaging tool according to any one of claims 2 to 6, further
including: a cylindrical heat-shrinkable film penetrating in a
direction of the pair of pressing pieces, wherein the
heat-shrinkable film is capable of covering by heat shrinkage a
part or whole of the packaging tool except the pair of standing
pieces, together with the object to be packaged mounted on the
mounting surface.
[0023] According to the packaging tool of claim 7, the
heat-shrinkable film covers a part or whole of the packaging tool
except the pair of standing pieces, together with the object to be
packaged, and thereby can surely hold the object to be packaged. On
the other hand, the pair of standing pieces are not covered and are
in a free state, thus enabling the object to be packaged to be
easily put into/out of the packaging box by grasping the standing
pieces by hands.
(Feature of Invention of Claim 8)
[0024] A packaging box according to the invention of claim 8
(hereinafter, referred to as a "packaging tool of claim 8") is a
packaging box for housing the packaging tool according to any one
of claims 2 to 7 and having an upper part being openable and
closable, formed in dimensions capable of restricting movements in
horizontal and vertical directions of the packaging tool when the
packaging tool is housed therein with the standing pieces standing
and the upper part is closed.
[0025] According to the packaging box of claim 8, the mounting part
of the housed packaging tool mainly restricts the movement in the
horizontal direction and the pair of standing pieces mainly
restrict the movement in the vertical direction. Though not
prohibiting the formation of an adhesive layer between the bottom
surface of the packaging box and the lower surface of the mounting
part, the restriction of the movements eliminates the need to bond
the rear surface of the mounting part to the packaging box, thus
facilitating the packaging work. Besides, at the time of taking out
the object to be packaged, it is only necessary to grasp the pair
of standing pieces and pull up the object to be packaged, so that
the packaging box is very convenient. Using no adhesive leads to
eliminate the environmental load.
(Feature of Invention of Claim 9)
[0026] A packaging tool according to the invention of claim 9
(hereinafter, referred to as a "packaging tool of claim 9") is the
packaging tool according to claim 1, further including: a
cylindrical heat-shrinkable film penetrating in a direction of the
pair of pressing pieces, wherein the heat-shrinkable film is
capable of covering by heat shrinkage a part or whole of the
packaging tool, together with the object to be packaged mounted on
the mounting surface.
[0027] According to the present invention, it is possible to
provide a packaging tool and a packaging box allowing a packaging
work to be performed without careful attention paid to rolling of
an object to be packaged.

[0034] An embodiment of the present invention (hereinafter,
referred to as "the present embodiment") will be described based on
the drawings. As illustrated in FIG. 1, a packaging tool 1 of the
present embodiment preferably includes a plate-shaped member 3
created, for example, by stamping it out from a sheet of corrugated
cardboard, and a heat-shrinkable film (thin film member) 5 covering
an object to be packaged as needed. The packaging tool 1 is for
holding an object to be packaged G between a part of the
plate-shaped member 3 and the heat-shrinkable film 5 and housing
the object to be packaged G into a packaging box 9. The packaging
box 9 is configured such that upper covers 9a to 9d thereof can be
opened/closed, and may be used as a packaging box as it is or may
be housed in a larger packaging box in a manner that two or more
boxes are placed side by side or stacked one on the other though
not illustrated.
(Schematic Configuration of Plate-Shaped Member)
[0035] As illustrated in FIG. 2 and FIG. 3, the plate-shaped member
3 is schematically composed of a mounting part 11, a pair of
standing pieces 13a, 13b, a pair of pressing pieces 15a, 15b, and a
pair of coupling pieces 17a, 17b which form a pair after
assembly.
[0036] The mounting part 11 includes a mounting surface 11a which
is an upper surface when placed on a table or the like, for
mounting the object to be packaged G thereon. The mounting surface
11a is rectangular and various in size depending on the size, the
shape and the number of the objects to be packaged. For example, to
package, in a stacked state, a cylindrical container made of a
synthetic resin containing a hair treatment therein and two
flexible containers containing refill liquid for the hair treatment
therein, namely, three containers in total as the object to be
packaged group G, for example, a mounting surface having dimensions
such as a long side of 25 cm and a short side of 18 cm can be
preferably used (hereinafter, a packaging tool having the
dimensions and dimensions described below is called a "sample
packaging tool").
(Structure of Standing Piece)
[0037] As illustrated in FIG. 2, at four sides surrounding the
mounting part (mounting surface 11a), bend lines 11k, 11k are
formed at one pair of opposed sides and bend lines 11m, 11m are
formed at another pair of opposed sides. Here, a pair of one and
another standing pieces 13a, 13b are formed via the bend lines 11k,
11k. The standing pieces 13a, 13b are rectangular pieces which can
bend and stand upward (to this side of a paper surface on FIG. 2)
via the bend lines 11k, 11k respectively. A height dimension of the
standing piece in the sample packaging tool viewed from the
mounting surface 11a is generally about 12 cm. As will be described
later, preferable standing pieces 13a, 13b have at least a function
of allowing fingers to grasp them at the time of inserting the
object to be packaged G (FIG. 1) into the packaging box 9 when
housing it or at the time of conversely taking it out, and a
function of restricting mainly a vertical movement in the packaging
box 9.
(Structure of Pressing Piece)
[0038] At the bend lines 11m, 11m, a pair of pressing pieces 15a,
15b are formed. The pressing pieces 15a, 15b are rectangular pieces
which can bend and stand upward via the bend lines 11m, 11m.
Preferably, at upper ends of the one and another pressing pieces
15a, 15b, one and another trapezoidal parts 15ad, 15bd having lower
bottoms of the same lengths as those of the pressing pieces 15a,
15b and tapering upward are continuously provided.
(Structure of Coupling Piece)
[0039] On both sides of the pressing piece 15a, one coupling small
piece 17ap and one coupling small piece 17bp are configured to be
able to bend, via bend lines 15s, 15s, in directions of both sides
of the opposed pressing piece 15b. On the other hand, on both sides
of the pressing piece 15b, another coupling small piece 17ap' and
another coupling small piece 17bp' are configured to be able to
bend, via bend lines 15s, 15s, in directions of both sides of the
opposed pressing piece 15a.
(Configuration of Coupling Structure)
[0040] At the end on the side of the coupling small piece 17ap
opposite to the bend line 15s, a mountain part 19an is formed, and
a narrow valley part 19as is formed on the bend line 15s side of
the mountain part 19an. The valley part 19as is open at the upper
end and formed to be almost parallel to the bend line 15s. On the
other hand, at the end on the side of the coupling small piece
17ap' opposite to the bend line 15s, an inverted mountain part
19an' is formed, and a narrow inverted valley part 19as' is formed
on the bend line 15s side of the inverted mountain part 19an'. The
valley part 19as' is open at the lower end and formed to be almost
parallel to the bend line 15s. Here, the coupling small piece 17ap
and the coupling small piece 17ap' are bent at the bend line 15s,
15s respectively toward the coupling small pieces opposed to each
other. At this time, additionally, the mountain part 19an is
inserted into the inverted valley part 19as' and the inverted
mountain part 19an' is inserted into the valley part 19as, whereby
both the coupling small pieces 17ap, 17ap' are detachably coupled
together in an almost linear state. The mountain part 19an, the
valley part 19as, the inverted mountain part 19an', and the
inverted valley part 19as' constitute one coupling structure 19a of
the present embodiment.
[0041] Next, another coupling structure 19b will be described. The
coupling structure 19b has the same structure as that of the one
coupling structure 19a. More specifically, at the end on the side
of the coupling small piece 17bp opposite to the bend line 15s, a
mountain part 19bn is formed, and a narrow valley part 19bs is
formed on the bend line 15s side of the mountain part 19bn. The
valley part 19bs is open at the upper end and formed to be almost
parallel to the bend line 15s. On the other hand, at the end on the
side of the coupling small piece 17bp' opposite to the bend line
15s, an inverted mountain part 19bn' is formed, and a narrow
inverted valley part 19bs' is formed on the bend line 15s side of
the inverted mountain part 19bn'. The valley part 19bs' is open at
the lower end and formed to be almost parallel to the bend line
15s. Here, the coupling small piece 17bp and the coupling small
piece 17bp' are bent at the bend line 15s, 15s respectively toward
the coupling small pieces opposed to each other. At this time,
additionally the mountain part 19bn is inserted into the inverted
valley part 19bs' and the inverted mountain part 19bn' is inserted
into the valley part 19bs, whereby both the coupling small pieces
17bp, 17bp' are detachably coupled together in an almost linear
state. The mountain part 19bn, the valley part 19bs, the inverted
mountain part 19bn', and the inverted valley part 19bs' constitute
the other coupling structure 19b of the present embodiment.
[0042] To couple the coupling structure 19a and the coupling
structure 19b, first, the pressing piece 15a and the pressing piece
15b need to be made to stand. This is because by bending the
coupling small pieces 17ap, 17ap', 17bp, 17bp' in a state where the
pressing pieces 15a, 15b are made to stand, the coupling structure
19a and the coupling structure 19b can be made to function.
Coupling of the coupling structure 19a and the coupling structure
19b causes the coupling small pieces 17ap, 17ap', 17bp, 17bp' to
stand and surround, in conjunction with the pressing pieces 15a,
15b, the object to be packaged G mounted on the mounting surface
11a. The surrounding prevents the object to be packaged G from
rolling down or collapsing from the top of the mounting surface
11a.
[0043] A virtual upper end of the coupling piece 17a (not
distinctively indicated in FIG. 2 and so on) when coupled by the
one coupling structure 19a is formed to be almost parallel to the
mounting surface 11a, and at the upper end, trapezoidal parts 17ad
having a lower bottom of the same length as a length of the upper
end and tapering upward are continuously provided. Further, an
upper end of the coupling piece 17b (not distinctively indicated in
FIG. 2 and so on) when coupled by the coupling structure 19b is
formed to be almost parallel to the mounting surface 11a, and at
the upper end, trapezoidal parts 17bd having a lower bottom of the
same length as a length of the upper end of the coupling piece 17b
and tapering upward are continuously provided. Here, the coupling
structure 19a is formed across the coupling piece 17a and the
trapezoidal parts 17ad, and the coupling structure 19b is formed
across the coupling piece 17b and the trapezoidal parts 17bd.
(Heat-Shrinkable Film)
[0044] The heat-shrinkable film 5 is preferably made by heat
shrinkage into a size capable of covering a part or whole of the
packaging tool 1 expect the pair of standing pieces 13a, 13b,
together with the object to be packaged G mounted on the mounting
surface 11a. It is desirable to select a heat-shrinkable film
having a material, size and heat shrinkage percentage so that the
trapezoidal parts 15ad, 15bd, 17ad, 17bd are curved by heat
shrinkage through the covering to cover over the object to be
packaged G. This is to prevent rolling and collapse during
transport by firmly holding the object to be packaged G.
(Packaging Procedure)
[0045] Next, the procedure of packaging the object to be packaged G
using the packaging tool 1 will be described referring to FIG. 1 to
FIG. 3.
[0046] First, the pressing pieces 15a, 15b are bent up along the
bend lines 11m, 11m in the state illustrated in FIG. 2. Next, the
coupling small pieces 17ap, 17ap', 17bp, 17bp' are bent along the
bend lines 15s, 15s, 15s, 15s and coupled by the coupling
structures 19a, 19b to complete the coupling pieces 17a, 17b. In
this event, the pair of standing pieces 13a, 13b are not bent up
but are left as they are. At this time, the mounting surface 11a is
in a state where lateral four sides are surrounded by the pressing
pieces 15a, 15b and the coupling pieces 17a, 17b.
[0047] Here, the object to be packaged G is mounted on the mounting
surface 11a and a portion except the pair of standing pieces 13a,
13b is covered by the heat-shrinkable film 5. In this state, the
object to be packaged G is substantially enclosed by the mounting
part 11 at the lower side, by the pressing pieces 15a, 15b and the
coupling pieces 17a, 17b at the lateral four sides, and by the
trapezoidal parts 15ad, 15bd, 17ad, 17bd at the upper side, and the
heat-shrinkable film further covers the outside of them.
Accordingly, the object to be packaged G is integrated with the
packaging tool 1, and therefore prevented from displacement,
rolling and collapse. As repeatedly mentioned, the pair of standing
pieces 13a, 13b are not covered but are in a free state.
[0048] Here, the pair of standing pieces 13a, 13b are made to
stand, the packaging tool 1 and the object to be packaged (G is
housed, while grasping the standing pieces 13a, 13b, into the
packaging box 9 with the upper covers 9a to 9d thereabove opened,
and the upper covers 9a to 9d are closed and sealed with an
adhesive tape (not illustrated), with which the packaging work is
completed. The inner dimensions of the packaging box 9 are made to
almost coincide with the maximum dimensions of the mounting part 11
and the standing pieces 13a, 13b, so that the movement of the
packaging tool 1 and the object to be packaged G is restricted in
the packaging box 9. Thus, it does need to bond the packaging tool
1 to the packaging box using an adhesive or the like.
[0049] For taking-out of the object to be packaged G, it is only
necessary to open the upper covers 9a to 9d and grasp and pull up
the standing pieces 13a, 13b. Then, by breaking the heat-shrinkable
film 5, the object to be packaged G can be taken. The packaging
tool 1 after removing the heat-shrinkable film is returned into a
sheet of corrugated cardboard by releasing the coupling structures
19a, 19b and returning the bent portions into original states.
Reuse and discard can be very easily performed.
Modified Example of the Present Embodiment
[0050] A modified example of the present modified example
(hereinafter, referred to as "the present modified example") will
be described referring to FIG. 4 to FIG. 6. The point of the
present modified example different from the present embodiment is
that the present embodiment includes the pair of standing pieces
which are omitted in the present modified example. Therefore, the
signs used in FIG. 1 to FIG. 3 are used as they are in FIG. 4 to
FIG. 6. However, the packaging tool 1 in the present embodiment is
represented as a packaging tool 1A in the present modified
example.
(Packaging Tool and Packaging Box)
[0051] As illustrated in FIG. 4, the packaging tool 1A of the
present modified example is common with the packaging tool 1 in
basic configuration and action including the point that the
packaging tool 1A preferably includes the plate-shaped member 3,
for example, by stamping it out from a sheet of corrugated
cardboard and the heat-shrinkable film (thin film member) 5
covering an object to be packaged as needed. Hereinafter, different
portions will be mainly described, and the description of common
portions will be omitted within a possible range so as to avoid
overlapping.
[0052] As repeatedly mentioned, the pair of standing pieces are
omitted in the present modified example. Therefore, four sides
surrounding the mounting part 11 (mounting surface 11a) are
composed of stamped-out ends 12k 12k at one pair of opposed sides
and bend lines 11m, 11m at another pair of opposed sides.
[0053] The preferable standing pieces 13a, 13b in the present
embodiment have a function of restricting mainly a vertical
movement in the packaging box 9, but the function is not obtained
in the present modified example. Hence, though absolutely
arbitrary, it is preferable to form an adhesive layer by an
adhesive B or its alternative between the bottom surface of the
packaging box 9 and the lower surface (rear surface) of the
mounting part 11 as illustrated in FIG. 4. This is to prevent
displacement and rolling around of the housed packaging tool 1A and
object to be packaged G during transport.
(Packaging Procedure)
[0054] Next, the procedure of packaging the object to be packaged G
using the packaging tool 1A will be described referring to FIG. 4
to FIG. 6.
[0055] First, the pressing pieces 15a, 15b are bent up along the
bend lines 11m, 11m in the state illustrated in FIG. 5. Next, the
coupling small pieces 17ap, 17ap', 17bp, 17bp' are bent along the
bend lines 15s, 15s, 15s, 15s and coupled by the coupling
structures 19a, 19b to complete the coupling pieces 17a, 17b. At
this time, the mounting surface 11a is in a state where the lateral
four sides are surrounded by the pressing pieces 15a, 15b and the
coupling pieces 17a, 17b.
[0056] Here, the object to be packaged G is mounted on the mounting
surface 11a and a possible range of the whole is covered by the
heat-shrinkable film 5. In this state, the object to be packaged G
is substantially enclosed by the mounting part 11 at the lower
side, by the pressing pieces 15a, 15b and the coupling pieces 17a,
17b at the lateral four sides, and by the trapezoidal parts 15ad,
15bd, 17ad, 17bd at the upper side, and the heat-shrinkable film
further covers the outside of them. Accordingly, the object to be
packaged G is integrated with the packaging tool 1A, and therefore
prevented from displacement, rolling and collapse.
[0057] Here, the packaging tool 1A is held and housed into the
packaging box 9 with the upper covers 9a to 9d thereabove opened,
and the upper covers 9a to 9d are closed and sealed with an
adhesive tape (not illustrated), with which the packaging work is
completed. Onto the bottom surface of the packaging box 9, the
adhesive B is dripped in advance (see FIG. 4). The inner dimensions
of the bottom surface of the packaging box 9 are preferably made to
almost coincide with the maximum dimensions of the mounting part
11, so that the movements in the horizontal direction and the
vertical direction of the packaging tool 1A and the object to be
packaged G in the packaging box 9 are restricted in cooperation
with the action of the adhesive B. Even in the case where the
maximum dimensions of the mounting part 11 are smaller than the
inner dimensions of the bottom surface of the packaging box 9, only
dripping the adhesive B can prevent the movements in the horizontal
direction and the vertical direction. Note that the adhesive B
illustrated in FIG. 4 may be configured to automatically drip by a
dispenser device or the like (not illustrated).
[0058] Taking-out of the object to be packaged G is performed by
opening the upper covers 9a to 9d and pulling it up while peeling
the adhesive (adhesive layer) B. By breaking the heat-shrinkable
film 5, the object to be packaged G can be taken. The packaging
tool 1A after removing the heat-shrinkable film 5 is returned into
a sheet of corrugated cardboard by releasing the coupling
structures 19a, 19b and returning the bent portions into original
states. Reuse and discard can be very easily performed.
