Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging container that can securely hold and store a contained item.

[0002]

[Prior art]

 When items are mailed or transported, they are stored in envelopes, cardboard boxes, or other containers before they are mailed or transported. However, if there is a gap between the item to be stored and the container, the item will move due to vibration that occurs during mailing or transportation, and the item will collapse in the container or the item itself will be damaged and the commercial value of the item will decrease. There is a case to let. Therefore, in order to prevent items from falling or being scratched by moving in a container such as an envelope or cardboard box during mailing or transportation, wrap the item with air matte etc. before storing it in a container or cushion with styrofoam or the like. The parts are placed in the container and mailed or transported. Therefore, when storing the product in a container, it is necessary to wrap the product in advance with an air mat, or to insert a cushioning member such as Styrofoam, which complicates the work. A cushioning material such as a mat or Styrofoam is required separately.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an packaging container that can easily and quickly hold and store an item and that does not require a cushioning member such as an air mat or styrofoam.

[0004]

[Means for Solving the Problems]

 The invention of claim 1 is characterized in that it has a container for accommodating an item, a pack body arranged inside the container, and an expander built in the pack body.

[0005]

[Action]

 When the product is to be stored in the packaging container according to the first aspect, a hole is formed in the packaging container after the product is put in the packaging container. As a result, the pack body provided inside the packaging container is also perforated, and the expansion body contained in the pack body expands to hold the product.

[0006]

First Embodiment FIGS. 1 to 3 show an envelope-shaped packaging container (10) according to the present invention. This packaging container (10) is formed in an envelope shape by adhering the bottom portion and side portions of a top sheet (12) and a back sheet (14) made of vinyl sheets. As a result, the accommodation portion (16) is formed in the packaging container (10). A lid portion (18) is continuously formed on the upper surface of the surface sheet (12), and an adhesive is applied to the back surface of the lid portion (18). A release sheet (20) is attached to this adhesive so that the adhesive does not inadvertently adhere. Therefore, the opening (16A) of the accommodating portion (16) can be closed by removing the release sheet (20) and folding back the lid portion (18). As shown in FIG. 2 and FIG. 3, a pack bag (22) as a pack body made of vinyl is attached to the back surface of the top sheet (12) and the back sheet (14) by an appropriate attachment means such as adhesion. Has been. The pack bag (22) contains a vacuum-packed polyurethane (24) as an expanded body in a contracted state. Further, an annular mark (26) is printed on the top sheet (12) and the lid (18), which serves as a mark when holes are formed in the top sheet (12) and the back sheet (14). ing. In this embodiment, the air inside the pack bag (22) is evacuated and the inside of the pack bag (22) is evacuated to form a shrinkable polyurethane bag (24). Also, a pack bag (22) having polyurethane (24) built in is attached to the back surface of the back sheet (14), but the other means for making the polyurethane (24) contract is a top sheet (12) and back sheet. After being attached to the back surface of (14), the air in the pack bag (22) may be evacuated to bring it into a vacuum state to shrink the polyurethane (24).

Next, the operation of the first embodiment will be described. When the product (A) is stored in the packaging container (10), the release sheet (20) is removed after the product (A) is placed in the storage portion (16), and the lid portion (18) of the topsheet (12) is then removed. And the lid portion (18) is adhered to the back sheet (14) to close the opening (16A) of the storage portion (16). Then, holes are formed in the marks (26) of the surface sheet (12) and the lid (18) by using appropriate means. As a result, holes are also formed in the pack bag (22), and air flows into the pack bag (22). Therefore, air also flows into the contracted polyurethane (24), and the polyurethane (24) expands to several times its volume in a short time (about 6 times in 1 minute in the test). Thereby, as shown in FIG. 3, the article (A) stored in the storage section (16) is sandwiched and held by the polyurethane (24) from both directions (left and right directions in FIG. 3). Therefore, the product (A) does not move in the packaging container (10) even if vibration occurs during mailing and transportation, so that the product (A) does not fall or is flawed. Therefore, the work of accommodating and holding the product (A) in the packaging container can be performed easily and quickly, and it is not necessary to separately prepare a cushioning member such as an air mat or Styrofoam. Moreover, since the polyurethane (24) also plays a role as a cushioning material by expanding, the article (A) can be further protected.

In the first embodiment, the vacuum-packed polyurethane (24) is attached to the back surface of the top sheet (12) and the back sheet (14) respectively, but only on the back surface of the top sheet (12), or The polyurethane (24) may be attached only to the back surface of the back sheet (14).

[0009]

Second Embodiment FIGS. 4 and 5 show an embodiment of a box-shaped packaging container (30) according to the present invention. The same members as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. The packaging container (30) has a rectangular cross section and is formed in an elongated shape, and includes a top plate (32), a bottom plate (34), a side plate (36), a side plate (38), a lid part (40), and Consists of a bottom (42). As shown in FIG. 5, a pack bag (22) is attached to the back surface of each of the top plate (32) and the bottom plate (34), and the pack bag (22) is vacuum-packed and contracted. (24) is built in. The other structure is similar to that of the first embodiment, and the description thereof is omitted.

Next, the operation of the second embodiment will be described. When the product (A) is stored in the packaging container (30), the product (A) is put into the storage part (16) and then the lid part (40) is closed. Then, holes are formed at appropriate places on the top plate (32) and the bottom plate (34) to form holes in the pack bag (22). As a result, when the air flows into the pack bag (22), the air also flows into the polyurethane (24) and the contracted polyurethane (24) expands several times in a short time. As a result, the article (A) housed in the housing section (16) is sandwiched and held by the polyurethane (24) from both directions. Further, since the packaging container (30) of this embodiment is formed in a box shape and has a long shape, it is extremely effective in conveying long objects such as golf clubs and skis, or goods when moving. is there. The other operations are the same as those in the first embodiment, and the description thereof will be omitted.

In the embodiment, the top sheet (12), back sheet (14), top plate (32), bottom plate (34), side plate (36) and side plate (38) are formed of vinyl sheets. Of course, the material is not limited to this, and may be formed of other material such as paper. Further, although the pack bag (22) is formed of vinyl in the embodiment, it is preferable that the pack bag (22) is subjected to an antistatic treatment when an electric / electronic board, a semiconductor or the like is housed as an item.

If the packaging container according to the present invention is used, a video tape, a printed wiring circuit board, a forehead, a photograph, a replacement part, an electronic device, a golf club, a precision instrument, glasses, a hearing aid, a dental implant, a photograph and a work of art. Various items such as sample products, souvenirs, blood transportation, medical products, moving materials, etc. can be safely and reliably mailed and transported.

[0013]

[Effect of device]

 As described above, the packaging container according to the present invention has an excellent effect that the product can be stored easily and quickly in a state of holding the product, and that it is not necessary to separately prepare a cushioning material.
