The case body 2 is formed by assembling sheet materials.
The sheet material forming the case body 2 is not particularly limited, and a conventionally known sheet material can be used.
Examples of the sheet material include a synthetic resin sheet, a synthetic resin sheet having a metal vapor deposition layer, cardboard, and a laminated sheet thereof. Preferably, a sheet including a synthetic resin sheet is used, and more preferably, a synthetic resin sheet (including a resin sheet in which two or more synthetic resin sheets are laminated) is used. Examples of the material of the synthetic resin sheet include polyolefins such as polypropylene and polyethylene, polyesters such as polyethylene terephthalate, polystyrenes, and polyamides.

Preferably, a sheet material that does not substantially deform at the shrinkage temperature of the tubular film 5 is used. Examples of such a sheet material include biaxially stretched synthetic resin sheets and cardboard.
The synthetic resin sheet is preferably colorless, but may be colored as long as the transparency is not impaired.
The thickness of the sheet material is not particularly limited, but is about 0.1 mm to 1.0 mm when a synthetic resin sheet is used. For example, when a polyester resin sheet is used, one having a thickness of 0.1 mm to 0.6 mm is preferable because it has appropriate rigidity. Moreover, when using thick paper, the thickness is about 0.4 mm-3 mm.
The case body 2 is printed with a desired design display such as a product name, a pattern, a product description, etc. as necessary.

  The peripheral wall 3 has a top sheet piece 6 and a back sheet piece 7. The top sheet piece 6 and the back sheet piece 7 are each formed, for example, in a square shape (preferably a rectangle or a square) in plan view. In this specification, the planar view shape means a shape when viewed from the normal direction of the object.

The first edge 61 (upper edge) of the top sheet piece 6 and the first edge 71 (upper edge) of the back sheet piece 7 are connected. Specifically, in the present embodiment, as shown in the development view of FIG. 6, one sheet material in which the first end side 61 of the top sheet piece 6 and the first end side 71 of the back sheet piece 7 are separated from each other. However, when this sheet material is assembled to form the case main body 2, the vicinity of the first edge 61 of the top sheet piece 6 and the vicinity of the first edge 71 of the back sheet piece 7 are bonded (heat fusion). Adhesion by wearing, or adhesion using an adhesive or a solvent). Therefore, in the case body 2 obtained, the first end 61 (upper end) of the top sheet piece 6 and the first end 71 (upper end) of the back sheet piece 7 are connected.
In FIG.1 and FIG.2, the said adhesion part of the surface sheet piece 6 and the back surface sheet piece 7 is represented by shading for convenience.

  Further, the second end side 62 (left end side) of the top sheet piece 6 and the second end side 72 (left end side) of the back sheet piece 7 are connected, and the third end side 63 (right end side) of the top sheet piece 6. The side facing the second end side 62 of the top sheet piece 6 and the third end side 73 of the back sheet piece 7 (the right end side; the side facing the second end side 72 of the back sheet piece 7) are connected. . In the present embodiment, as shown in the development view of FIG. 6, the second end side 62 of the top sheet piece 6 and the second end side 72 of the back sheet piece 7 are integrated via a crease line, and the back sheet piece 7. Since the sheet material in which the adhesive margin 9 is extended to the third end side 73 of the sheet is used, when the case body 2 is formed by assembling the sheet material, both sheet pieces 6, 7 is bent and the adhesive margin 9 is adhered to the vicinity of the third end 63 of the top sheet piece 6.

On the other hand, the fourth end side 64 (lower end side) of the top sheet piece 6 and the fourth end side 74 (lower end side) of the back surface sheet piece 7 are not connected to each other, and the product is placed on the fourth end sides 64 and 74 side. A slot 21 is opened (see FIG. 4).
In the packaging case 1 of the present embodiment, the merchandise entry / exit opening 21 is in an open state, but if necessary, a flap piece (not shown) that can open / close the merchandise entry / exit opening 21 is attached to the top sheet piece 6 or / And you may extend from the back surface sheet piece 7. FIG.

  In the case body 2, the peripheral wall 3 is constituted by the top sheet piece 6 and the back sheet piece 7, and a product storage space 31 is formed inside the peripheral wall 3 (see FIG. 4). In addition, in the state which does not store goods, the surrounding wall 3 becomes the substantially flat shape where the surface sheet piece 6 and the back surface sheet piece 7 adjoin. Then, as shown in FIG. 5, the product A can be inserted into the product storage space 31 by expanding the top sheet piece 6 and the back sheet piece 7.

A tubular film 5 having heat shrinkability is inserted into the product storage space 31 of the peripheral wall 3.
The cylindrical film 5 is substantially flat like the peripheral wall 3 in a state in which no product is stored, but is expanded into a cylindrical shape when the product is inserted.
The cylindrical film 5 has a cylindrical shape having openings at the top and bottom, and is formed in a size (inner diameter) that can be fitted on a product. The cylindrical film 5 is arranged in such a manner that its longitudinal axis (a line connecting the center of the upper opening and the center of the lower opening) is substantially orthogonal to the fourth end side 64 of the surface sheet piece 6. Has been inserted inside. Further, the cylindrical film 5 has a lower end edge (an end edge forming the lower opening) substantially matching or in the vicinity of the fourth end sides 64 and 74 of the top sheet piece 6 and the back sheet piece 7. Has been placed.

The tubular film 5 folded in a substantially flat shape is smaller than the width of the top sheet piece 6 and the back sheet piece 7 as shown in the figure.
A part of the outer surface of the tubular film 5 is bonded to the inner surface of at least one of the top sheet piece 6 and the back sheet piece 7. Since many shrinkage | contraction area | regions of the cylindrical film 5 can be ensured, it is preferable that the cylindrical film 5 is adhere | attached only on either one inner surface of the surface sheet piece 6 or the back surface sheet piece 7. FIG. In particular, it is preferable that a part (for example, the central portion) of the outer surface of the tubular film 5 is bonded to the inner surface of the top sheet piece 6 and the inner surface of the back sheet piece 7, respectively. By adhering the outer surface of the tubular film 5 to the opposing sheet pieces 6 and 7, respectively, the top sheet piece 6 and the back sheet piece 7 can be spread apart, and at the same time, the tubular film 5 can be spread. .
Hereinafter, a portion where the tubular film 5 and the sheet pieces 6 and 7 are bonded is referred to as an adhesive portion, and a reference numeral 8 is attached to the drawing.
Further, in order to make it easy to understand the region where the bonding portion 8 is provided, the bonding portion is indicated by light ink painting in FIGS. 1 and 2.
The method for adhering the tubular film 5 and the sheet pieces 6 and 7 is not particularly limited. Adhesion using a known adhesive such as a solvent-type adhesive or a heat-sensitive adhesive, adhesion using a solvent, or pressure-sensitive adhesive tape Adhesion using can be mentioned.

In the case main body 2 (the case main body 2 having the product entrance / exit 21 at the lower end) as in the present embodiment, the cylindrical film 5 is provided in the vicinity of the product entrance / exit 21. It is preferable. If the tubular film 5 is provided in the vicinity of the commodity entrance 21, it is easy to insert the commodity into the tubular film 5, and the heat medium easily spreads over the tubular film 5 during heating.
The tubular film 5 is formed from a heat-shrinkable film that can be heat-shrinked at a shrinkage temperature (for example, about 80 to 100 ° C.), and is preferably formed from a transparent (including colored and transparent) heat-shrinkable film. The tubular film 5 is configured by making this heat-shrinkable film into a cylindrical shape and bonding the both side ends thereof.
The material of the heat-shrinkable film is not particularly limited as long as it can heat-shrink in at least one direction (circumferential direction when formed into a cylindrical shape, hereinafter the same), and a thermoplastic resin such as a polyester-based resin. A film-made film can be used.
Moreover, the cylindrical film 5 can also be formed using the laminated | multilayer film by which the functional layer (a gas barrier layer, a light barrier layer, a heat insulation layer, etc.) was laminated | stacked on the heat-shrinkable film.
A design print layer may be provided on the front surface and / or the back surface of the tubular film 5 as necessary.

The heat shrinkage rate (immersion in 90 ° C. warm water for 10 seconds) in one direction of the heat shrinkable film is, for example, about 30% or more, preferably about 40% or more. In addition, the heat-shrinkable film may be slightly heat-shrinked in the other direction (direction orthogonal to one direction in the film plane), About -3 to 10%.
However, thermal shrinkage rate (%) = [{(original length in one direction (or other direction)) − (length after immersion in one direction (or other direction))} / (one direction (or other direction) ) Original length)] × 100.
Although the thickness of a heat-shrinkable film is not specifically limited, Generally, they are 20 micrometers-200 micrometers, Preferably they are 30 micrometers-100 micrometers.

The packaging case 1 of the present invention having the above configuration is used as follows, for example.
A product is inserted into the tubular film 5 from the product entrance 21 of the case body 2.
The product is not particularly limited, and various products can be packaged. Examples of the products include cosmetic containers, sanitary containers, medicines or quasi-drug containers, beverage containers, toys, machine parts, and the like.
The outer shape of the product is not particularly limited, but an outer shape having an uneven surface, an outer shape having a curve in the vertical direction, etc. (an outer shape that is not a columnar shape such as a columnar shape or a quadrangular prism shape) is preferable. Since the tubular film 5 strongly adheres to the product due to heat shrinkage, even if it is a columnar product, the tubular film holds it, so the possibility of falling off is low. However, as in the present embodiment, in the case main body 2 in which the merchandise entry / exit opening 21 is opened, it is necessary to securely hold the merchandise A. For this reason, if the outer shape is a non-columnar product, the tubular film 5 adheres along the unevenness of the product, so that the product can be reliably prevented from falling off.

Preferably, the product is inserted into the tubular film 5 so that the bottom surface of the product is positioned on the fourth end sides 64 and 74 of the top sheet piece 6 and the back sheet piece 7.
Next, in order to heat the tubular film 5, for example, hot air at a predetermined temperature is blown. The cylindrical film 5 is thermally contracted in the circumferential direction by heating, and is in close contact with the outer surface of the product.
Since the tubular film 5 is partially bonded to the peripheral wall 3 (not bonded to the peripheral wall 3 over the entire circumferential direction), the tubular film 5 is sufficiently heat-shrinked to be in close contact with the product.

In the obtained package, as shown in FIG. 7, the product A put in the case body 2 is held on the peripheral wall 3 via the tubular film 5. Therefore, it is possible to prevent the product A from moving during the distribution process of the package.
Thus, the packaging case 1 of this invention can be easily hold | maintained so that a goods may not be moved only by heat-shrinking the cylindrical film 5. FIG. Furthermore, the heat-shrinkable tubular film 5 can be in close contact with the outer surface of the product by heat shrinkage regardless of the shape of the product. Therefore, the packaging case 1 of the present invention can store various products so as not to move.

In addition, this invention is not restricted to the packaging case shown in the said embodiment, A design change can be suitably carried out in the range which this invention intends. Hereinafter, although the modification of the packaging case of this invention is demonstrated, the term and code | symbol are used about the structure similar to the said embodiment.
In the said embodiment, although a part of cylindrical film 5 is each adhere | attached on the inner surface of the surface sheet piece 6 and the back surface sheet piece 7, it replaces with this, and a part of cylindrical film 5 is the surface sheet piece 6 or It may be adhered to only one of the inner surfaces of the back sheet piece 7. However, it is preferable that a part of the tubular film 5 is bonded to the top sheet piece 6 and the back sheet piece 7 as in the above embodiment because the product can be fixed to the case body 2 with less movement.

Furthermore, in the said embodiment, although the surrounding wall 3 is formed from the surface sheet piece 6 and the back surface sheet piece 7, it is not limited to this. For example, the peripheral wall 3 may be formed in a substantially cylindrical shape, a substantially square tube shape, a substantially hexagonal tube shape, or the like.
8 and 9 show the packaging case 1 in which the case main body 2 is formed in a hollow, substantially rectangular parallelepiped shape. The cylindrical film 5 is inserted into the product storage space 31 of the case body 2. A part of this cylindrical film 5 is bonded to one inner surface of the peripheral wall 3 (bonding portion 8).

Further, as shown in FIG. 10, two or more cylindrical films 5 and 5 may be provided in the peripheral wall 3. These cylindrical films 5 and 5 are arranged at intervals in the vertical direction, and a part of each cylindrical film 5 and 5 is bonded to the inner surface of the peripheral wall 3.
In FIG. 10, the bonding portion 8 is represented by light ink painting.

  When two or more cylindrical films 5 are provided as described above, the cylindrical films 5 may be provided in the peripheral wall 3 (not shown) so that the respective cylindrical films 5,. In this case, for example, a part of one cylindrical film 5 is bonded to one surface of the peripheral wall 3, and a part of the cylindrical film 5 provided beside the cylindrical film 5 is attached to the other surface of the peripheral wall 3. Glued.

Furthermore, you may provide a sticking part in a part of inner surface of the cylindrical film 5 (not shown). This sticking part can be provided by applying an adhesive (or a pressure-sensitive adhesive) to a part of the inner surface of the tubular film 5 (for example, a substantially rectangular part in plan view at the center in the vertical direction). The adhesive (or pressure-sensitive adhesive) is preferably a heat-sensitive adhesive (or pressure-sensitive adhesive) because blocking does not occur even when the tubular film 5 is folded into a substantially flat shape. A heat-sensitive adhesive (or pressure-sensitive adhesive) is an agent that does not exhibit adhesiveness at room temperature and produces an adhesive force upon heating. Such a heat-sensitive adhesive (or pressure-sensitive adhesive) generates an adhesive force by heat when the tubular film 5 is thermally contracted.
When the said sticking part is provided, the inner surface and goods of the cylindrical film 5 adhere | attach partially through the sticking part. Therefore, even if the product has a columnar outer shape, the product can be reliably held by the tubular film 5.

  Moreover, even if it inserts goods and heat-shrinks the cylindrical film 5 so that the lower part of the cylindrical film 5 after heat contraction may closely_contact | adhere to the peripheral part of the bottom face of goods, the goods which have a columnar external shape fall out. Can be prevented. In particular, it is more effective when the tubular film 5 provided with the sticking part is brought into close contact with the peripheral part of the bottom surface of the product as described above. In this case, it is preferable that the adhesive portion 8 is provided in a range excluding the lower portion of the tubular film 5 so that the thermal contraction of the lower portion of the tubular film 5 is not restricted. Although FIG. 1 is an example in which the adhesive portion 8 is not provided in the lower portion of the tubular film 5, the lower edge of the tubular film 5 may be further extended downward.

  The packaging case of the present invention can be used for applications in which various products are stored and displayed.
