JP6720460B2 - Display bag with gusset and its manufacturing method - Google Patents

Description

TECHNICAL FIELD The present invention relates to a display bag with a gusset that can be conveyed in a folded state and can be spread like a blister pack when used, and a manufacturing method thereof.

Blister packs are often used to store products in a transparent package and display the products. As a store display method, products are suspended and displayed through a bar-shaped display bar on the suspension header above the package. The transparent package is formed by molding a plate-shaped plastic with a vacuum foam or the like to form a transparent storage portion projecting forward. Then, there is a type in which a product is put in the storage part and a mount or plastic which becomes a fixed base is thermocompression bonded to the rear surface of the storage part, or a type in which the fixed base is mounted in a slide type without thermocompression bonding.

However, this blister pack has a disadvantage that a large volume is required for transporting a container before use, because the storage part is greatly expanded and bulky. Therefore, there has been proposed a display bag with a gusset that is formed by forming a thin film-shaped storage portion and providing a transverse gusset in the storage portion so as to be foldable. According to such a display bag with a gusset, by folding the storage portion along the gusset portion, the bag can be transported in a more compact state than the blister pack.

The display bag with a gusset described in Patent Document 1 is one in which a packaging bag with a side gusset is provided under a hanging header, and the packaging bag with a side gusset for storing products is hung by the hanging header. It is configured as follows.

On the other hand, Patent Document 2 describes a display bag with a gusset, which the applicant previously proposed. In this display bag with a gusset, a storage portion having a lateral gusset and a storage portion having a bottom gusset can be provided below the hanging header. With this gusseted display bag, it can be transported compactly when not in use, and when used, we succeeded in storing the product by greatly expanding the storage part like a blister pack.

JP-A-2002-37273 Japanese Patent No. 5327995

Each of the conventional display bags with a gusset has a structure in which an opening is closed after a product is stored from upper and lower end portions where the storage portion is opened. Therefore, the storage portion before storing the product has a configuration in which the open end portion greatly expands. Since this opening portion is partially bulky during transportation, there is a problem during transportation.

That is, due to the property of the thin film of synthetic resin, there is a restoration phenomenon in which the gusset portion gradually opens even when the gusset portion provided in the storage portion is folded. Therefore, even if the storage portion is folded along the gusset portion, the storage portion will gradually expand. In particular, the opening formed at one end of the storage section swells more than the other end that is closed in advance, so it has a special shape in which only one side of the storage section bulges unevenly. Therefore, the opening is bulky at the time of transportation, and although it is not as large as a blister pack, a certain volume is required, and there is a possibility that the transportation work may be hindered due to the special shape that only one side swells.

Moreover, in the configuration in which the bottom gusset is provided in the storage section, the folded bottom gusset as well as the opening swells due to the restoration phenomenon, resulting in a disadvantage that the volume during transport becomes larger.

These gusseted display bags have the advantage that they can be transported compactly by folding the storage part, which bulges like a blister pack. However, the conventional display bag with a gusset cannot fully utilize its original advantages due to the restoration phenomenon of the storage part.

Therefore, the present invention was created in order to solve the above-mentioned problems, and it is possible to convey compactly while maintaining the folded state of the storage part, and greatly expands the storage part during use to make products like a blister pack.

Further, it is possible to form the back body 13 having the product storage port 10A, the sealing piece 14 for sealing the product storage port 10A, or the pressure bonding piece 12 by the die-cutting process 100 (FIG. 2).

The assembling process 200 is a process of assembling the unfolding die 20A to form the storage portion 20 as shown in FIG. In this step, when the box-shaped storage portion 20 is formed, as described above, the lateral gusset portion 21A, the bottom gusset portion 21B, and the upper gusset portion 21C are formed, and the left and right joint pieces 22, the lower joint piece 23, This is a process of assembling the expansion die 20A in which the upper joining piece 24 is formed (see FIGS. 7A and 7B). Then, the left and right joint pieces 22 and the upper and lower joint pieces 23, 24 are assembled so as to project around the box-shaped storage portion 20 (see FIGS. 8A and 8B). After that, the storage portion 20 is folded from each gusset portion 21 to form the flat storage portion 20 (see FIGS. 9A and 9B). It should be noted that FIG. 8A is a view of the folded storage portion 20 as viewed from the back, and FIG.

In the welding step 300, the storage part 20 folded flat along the gusset part 21, the crimping piece 12 arranged on the front side of the storage part 20, and the back body 13 arranged on the rear surface side of the storage part 20. This is a process of heat welding at the same time (see FIG. 2). Then, the fixed base 10 is formed by the back body 13 and the crimping pieces 12 welded in the welding step 300, and the hanging header 11 is formed on the upper portion (see FIG. 1 ). The illustrated example shows a case where the box-shaped storage portion 20 is formed. The rear body 13 is formed with a product storage port 12A, and a sealing piece 14 for sealing the product storage port 12A is formed. (See FIG. 2).

In this step, the peripheral portions of the crimping piece 12 are overlapped on the front side of the left and right joint pieces 22, the upper and lower joint pieces 23, 24, and the back body 13 and the sealing piece 14 are overlapped on the rear side of the left and right joint pieces 22. Then, the pressure bonding piece 12, the back body 13, and the sealing piece 14 are heat-welded at the same time through the upper and lower joining pieces 23 and 24 (see FIG. 2 ).
