Hereinafter, an embodiment of a packaging tool with a package according to the present invention will be described with reference to FIGS. 1 to 7. In all the drawings below, the thicknesses and dimensional ratios of the constituent elements are appropriately changed in order to make the drawings easy to see.
As shown in FIGS. 1 to 3, the packaging device 1 with a package body of the present embodiment includes a packaging device 2 and a packaging material 3 such as a bottle.
The packaging tool 2 has a sheet-like front panel (second main body) 11 and a rear panel (main body) 12, and is provided on one surface 12 a of the back panel 12 and a mount 10 formed in a tubular shape as a whole. And a shrink film 30 which is formed in a cylindrical shape and is provided on the opposite side of the rear panel 12 of the adhesive portion 20 and holds the package body 3 in its own cylindrical hole 31.

The term “cylindrical shape” as used herein means that the cross section perpendicular to the axis C of the mount 10 includes not only the shape of an edge of a circle but also the shape of an edge such as an ellipse or a polygon.
In addition, in FIG. 3, the cross section of the packaging tool 1 with a to-be-packaged body in two places in the axis C direction is shown.

  The front panel 11 and the rear panel 12 are each formed in a rectangular shape when viewed in parallel with the thickness direction X of the rear panel 12. The front panel 11 and the rear panel 12 are stacked in the thickness direction X and sandwich the adhesive portion 20 and the shrink film 30. One edge of the rear panel 12 and one edge of the front panel 11 are connected (joined), and the other edge on the side opposite to the one edge of the rear panel 12 and one of the front panel 11 The other edge that is opposite to the edge is continuous.

The front panel 11 and the rear panel 12 are aligned at the end of one side Y1 in the axis C direction of the mount 10, but the other side Y2 in the axis C direction is closer to the end of the front panel 11 than the end of the rear panel 12. Protrudes and constitutes a protruding portion 11a. A through hole 11 b is formed in the protruding portion 11 a of the front panel 11. In this example, the through hole 11 b is formed in the center portion of the front panel 11 in the width direction Z. The width direction Z is a direction orthogonal to the axis C direction and the thickness direction X, respectively.
A window portion 11c is formed on one side Y1 in the direction of the axis C from a portion of the front panel 11 sandwiching the shrink film 30, that is, a portion where the through hole 11b is formed.

The rear panel 12 is provided with a pair of perforations (easy cutting lines) 12b and 12c extending in the creeping direction along one surface 12a of the rear panel 12. In this example, the creeping direction coincides with the direction of the axis C of the mount 10.
The perforation 12b is formed by a plurality of through holes 12d penetrating the rear panel 12 in the thickness direction X. The length of each through hole 12d in the direction of the axis C is, for example, about 0.5 mm to 1.5 mm. Of the plurality of through holes 12d, the length of the end portion on one side Y1 in the axis C direction is relatively long, for example, 2 mm to 3 mm. The perforation 12b extends from the end of one side Y1 of the rear panel 12 in the axis C direction to the middle portion of the rear panel 12 in the axis C direction.
The perforation 12c is configured similarly to the perforation 12b. That is, the perforation 12c is formed by a plurality of through holes 12e.

The rear panel 12 is provided with a perforation (plate part side easy auxiliary cutting line) 12f that connects the ends of the other side Y2 in the direction of the axis C of the perforations 12b and 12c. The perforation 12f is formed by a plurality of through holes whose symbols are omitted. The perforation 12 f extends in the width direction Z of the rear panel 12.
The perforations 12b, 12c, and 12f have lower rigidity than other portions of the rear panel 12, and can be easily cut. A band-shaped cut band 12g is defined at a portion of the rear panel 12 between the perforation 12b and the perforation 12c.

Between the front panel 11 and the rear panel 12, the packaged body 3 accommodated in the cylindrical hole 31 of the shrink film 30 is sandwiched. For this reason, the front panel 11 is curved so that the central portion in the width direction Z is convex toward the direction away from the rear panel 12. Similarly, the rear panel 12 is curved so that the central portion in the width direction Z is convex toward the direction away from the front panel 11.
The panels 11 and 12 that do not hold the package 3 have flat shapes as a whole.
The front panel 11 and the rear panel 12 are integrally formed by cutting and assembling various types of paperboard such as unbleached kraft paper, bleached kraft paper, and white paperboard into the shape of a blank sheet 10A described later. The front panel 11 and the rear panel 12 may be formed of a plastic sheet.

As shown in FIG. 3, the shrink film 30 has a cylindrical shape by bending a sheet-like film into a tubular shape, overlapping and adhering both edges of the film, and providing an envelope pasting portion 32. ing. As the material of the shrink film 30, polystyrene, polyvinyl chloride, polypropylene, polyethylene, or polyester resin is preferably used. As the polyester-based resin, polylactic acid, which is a sustainable material derived from agricultural products, can be used, and it can be preferably used as packaging suitable for the environment.
The shrink film 30 is not particularly limited as long as it is a film that shrinks by heat. Moreover, when shrinkage | contraction of the circumferential direction of the shrink film 30 is larger than shrinkage | contraction of an axial direction, since the to-be-packaged body 3 does not remove | deviate from the shrink film 30 at the time of shrinkage | contraction at the time of shrink packaging, it is suitable for this use. .

The shrink film 30 is provided with a pair of perforations (film-side easy cutting lines) 33 and 34 extending in the direction of the axis C. The perforations 33 and 34 have lower rigidity than other portions of the shrink film 30 and can be easily cut.
A band-shaped film-side cut band 35 is defined at a portion of the shrink film 30 having a narrower width between the perforation 33 and the perforation 34.

When viewed in parallel with the thickness direction X, the perforation 33 overlaps (including substantially overlaps) the perforation 12b, and the perforation 34 overlaps the perforation 12c.
In this example, the shrink film 30 holds the entire packaged body 3 formed in a cylindrical shape in its own cylindrical hole 31. In addition, the shape of the to-be-packaged body 3 is not specifically limited, A cylindrical shape may be sufficient like this embodiment, and flat form may be sufficient as it.
The shrink film 30 covers the outer peripheral surface of the package body 3 and extends to the one side Y1 in the axis C direction beyond the package body 3 as shown in FIG. .
Of the shrink film 30 extending to the one side Y1 in the axis C direction, except for the portion attached to the rear panel 12 by the adhesive portion 20 in the circumferential direction, the edge of the bottom surface of the package 3 is covered by heat shrinking. ing.

The outer peripheral surface of the shrink film 30 is attached to the rear panel 12 by an adhesive portion 20. The shrink film 30 is attached to the rear panel 12 such that its own axis is parallel to the axis C of the mount 10. The package body 3 is held by the shrink film 30 such that its own axis is parallel to the axis C of the mount 10.
As shown in FIG. 1, the packaged body 3 held by the shrink film 30 can be viewed from the outside through the window portion 11 c of the front panel 11.

  As the adhesive part 20, a known adhesive such as glue or hot melt can be appropriately selected and used. As shown in FIGS. 2 and 3, the bonding portion 20 is formed in a band shape extending in the direction of the axis C, and is provided on one surface 12 a of the cutting band 12 g of the rear panel 12.

As shown in FIG. 4, the position of the end 12h on one side Y1 in the axis C direction of the cutting band 12g is one side Y1 in the axis C direction relative to the position of the end 36 on the one side Y1 in the axis C direction of the shrink film 30. It is. The end 36 of the shrink film 30 is an end on one side Y1 in the axis C direction of the portion where the adhesive portion 20 is attached in the circumferential direction of the shrink film 30.
The position of the end 36 of the shrink film 30 is one side Y1 in the axis C direction from the position of the end 21 on the one side Y1 in the axis C direction of the bonding portion 20. The position of the end 21 of the bonding portion 20 is one side Y1 in the axis C direction relative to the position of the end 3a on the one side Y1 in the axis C direction of the package 3.

The shape which developed the packaging tool 2 comprised as mentioned above is demonstrated using FIG.
In the developed packaging tool 2, a front panel 11 and a rear panel 12 are connected via a fold part 14. The fold portion 14 is a portion where the thickness of the paperboard constituting the mount 10 is reduced.
At the edge of the rear panel 12 opposite to the front panel 11, a flap-like folded portion 15 is provided via a fold portion 14.
The front panel 11 has a through hole 11b and a window portion 11c.

The rear panel 12 has perforations 12b, 12c, and 12f, and an adhesive portion 20 is provided on a cut band 12g defined between the perforation 12b and the perforation 12c of the rear panel 12. The shrink film 30 before heat shrinking is affixed to the adhesive portion 20.
The front panel 11, the rear panel 12, the folding part 15, and the fold part 14 constitute a blank sheet 10A. The blank sheet 10A is formed by cutting a paperboard with a mold or the like.

10 A of blank sheets comprised as mentioned above are folded by the fold part 14, and the packaging tool 2 is assembled by affixing the folding part 15 to the front panel 11 by the paste part which is not shown in figure. At this time, each of the panels 11 and 12 has a flat shape.
In order to hold the packaging body 3 in the packaging tool 2, first, packaging is performed in the cylindrical hole 31 of the shrink film 30 through the opening on the one side Y <b> 1 in the axis C direction between the front panel 11 and the rear panel 12. Insert body 3. At this time, the package body 3 is arranged so that the shrink film 30 protrudes from the package body 3 to the one side Y1 in the axis C direction and the other side Y2 in the axis C direction.
The packaging tool 2 and the package body 3 are placed in a known shrink tunnel and heated to about 180 ° C. The heated shrink film 30 is heat-shrinked and covers and holds the outer peripheral surface of the package 3.
By the above process, the packaging tool 1 with the package body in which the package body 3 is held in the packaging tool 2 is manufactured.

The wrapping tool 1 with the package body configured as described above is arranged on the table top so that the axis C of the mount 10 is substantially parallel to the vertical direction and the other side Y2 in the direction of the axis C is upward at, for example, a storefront. Or a bar-like member inserted into the through hole 11b of the front panel 11 and suspended.
The position of the end 21 of the bonding portion 20 is one side Y1 in the direction of the axis C relative to the position of the end 3a of the body 3 to be packaged so that the other side Y2 in the direction of the axis C is on the upper side. When the wrapping tool 1 is erected, it is possible to prevent the packaged body 3 from coming out of the shrink film 30 downward.

When the packaged body 3 is taken out from the packaging tool with packaged body 1, the following procedure is performed.
While holding both edges of the front panel 11 with one hand from the front panel 11 side, the user grasps the end of the one side Y1 in the direction of the axis C of the cutting band 12g with the other hand.
As shown in FIG. 6, when the end of the cut band 12g that has been picked up is pulled away from the rear panel 12, the perforations 12b, 12c, and 12f are less rigid than the other parts of the rear panel 12. The perforations 12b and 12c are cut from one side Y1 in the axis C direction. Further, since the perforations 33 and 34 have lower rigidity than the other portions of the shrink film 30, the perforations 33 and 34 are cut from one side Y1 in the axis C direction. At this time, each through hole 12d of the perforation 12b and each through hole 12e of the perforation 12c expands or tears.
When viewed in the thickness direction X, the perforations 33 overlap the perforations 12b, and the perforations 34 overlap the perforations 12c. For this reason, the force which cut | disconnects the perforations 12b and 12c of the rear panel 12 can be made to act on the perforations 33 and 34 of the shrink film 30 efficiently.

The position of the end 12h of the cutting band 12g, the position of the end 36 of the shrink film 30, and the position of the end 21 of the bonding portion 20 are one side Y1 in the axis C direction from the position of the end 3a of the package 3. For this reason, the user can surely pick the end 12h of the cutting band 12g, and the user's force can be reliably transmitted to the cutting band 12g.
Moreover, when the shrink film 30 protrudes below the package 3, the perforations 33 and 34 provided in the shrink film 30 are widened when heated in the shrink tunnel. Therefore, the perforations 33 and 34 have lower rigidity and can be easily cut.

  When the perforations 12b, 12c, 12f of the rear panel 12 and the perforations 33, 34 of the shrink film 30 are cut, the cut band 12g is separated from the rear panel 12 as shown in FIG. The film side cutting band 35 is separated. The shrink film 30 is opened by separating the film-side cutting band 35 from the shrink film 30. Note that FIG. 7 does not show the shrink film 30 from which the film-side cutting band 35 is separated.

  The user deforms the rear panel 12 so as to widen the space between the perforation 12b and the perforation 12c, and deforms the shrink film 30 so as to widen the space between the perforation 33 and the perforation 34. The package 3 is taken out between the perforations 33 and 34 of the shrink film 30 and between the perforations 12b and 12c of the rear panel 12.

As described above, according to the packaging tool 2 and the packaging tool 1 with the package body of the present embodiment, the position of the end 12h of the cutting band 12g, the position of the end 36 of the shrink film 30, and the end 21 of the adhesive portion 20. The position and the position of the end 3a of the package 3 are as described above. For this reason, when the cut band 12g is cut out from the rear panel 12, the shrink film 30 can be reliably opened without causing the paper strip where the cut band 12g and the adhesive portion 20 are separated.
The shrink film 30 is provided with a pair of perforations 33, 34. When viewed in the thickness direction X, the perforations 33 overlap the perforations 12b, and the perforations 34 overlap the perforations 12c. Therefore, the film-side cutting band 35 that is a portion between the perforation 33 and the perforation 34 can be efficiently separated from the shrink film 30, and the shrink film 30 can be opened more reliably.

Since the perforations 12b, 12c extend in the direction of the axis C, the force for pulling up the end of the cutting band 12g can be efficiently transmitted to the entire cutting band 12g.
Since the shrink film 30 extends beyond the package body 3 to one side Y1 in the direction of the axis C, the package body 3 is pulled out from the shrink film 30 even when the packaging tool 2 receives an impact from below. There is no.
The position of the end 12h of the cutting band 12g, that is, the position of one end Y1 in the axis C direction of the mount 10 is one side Y1 in the axis C direction relative to the position of the end 3a of the package 3. Therefore, for example, even when the packaged body 3 has a shape that cannot stand by itself, the packaging tool 2 that holds the packaged body 3 can be made independent. The position of the package 3 in the direction of the axis C with respect to the mount 10 can be freely determined.

In the present embodiment, in the axis C direction, the position of the end 12h of the cutting band 12g may be equal to the position of the end 36 of the shrink film 30, and the position of the end 36 of the shrink film 30 is the end of the adhesive portion 20. It may be equal to position 21.
Even if comprised in this way, there can exist an effect similar to the packaging tool 2 of this embodiment, and the packaging tool 1 with a to-be-packaged body.

As mentioned above, although one embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and modifications, combinations, and deletions within a scope that does not depart from the gist of the present invention. Etc. are also included.
For example, in the embodiment, the packaging tool 2 does not need to include the front panel 11. In this case, the creeping direction in which the pair of perforations 12b and 12c extends is not particularly limited as long as it is a direction along one surface 12a of the rear panel 12.

The easy cutting lines are perforations 12b and 12c, and the plate-side easy auxiliary cutting lines are perforations 12f. However, the board-side easy cutting line and the board-side easy auxiliary cutting line may be a half-cut part in which the strength is reduced by cutting the paperboard from the surface of the paperboard to the middle part in the thickness direction of the paperboard.
The pair of perforations 33 and 34 may not be provided in the shrink film 30. When the shrink film 30 is formed of a low-strength material or when the thickness of the shrink film 30 is thin, the shrink film 30 can be opened simply by pulling the adhesive portion 20 attached to the shrink film 30. Because.
Although the main body is the rear panel 12 of the mount 10, the main body may constitute a box-shaped side plate. In this case, the packaged body 3 is arranged in a state of being held by the shrink film 30 in the internal space of the box-shaped body.
