Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a packaging container used for selling ice cream, cake, etc.

[Conventional technology]

A side plate piece is attached to each side of the bottom plate, a cover plate piece is attached to one set of opposing side plate pieces of these side plate pieces, and a folding piece is attached to the side plate piece of the other set of opposing side plate pieces, respectively. Packaging boxes that can be assembled into a box shape by folding the sheet materials at respective hinges using continuous sheet materials are conventionally known, and the sheet materials are made of paperboard whose inner surface is coated with wax. are commonly used.

[Problem that the invention attempts to solve]

The well-known prefabricated packaging boxes mentioned above have poor insulation properties, and require the use of ice packs such as dry ice to keep the stored items at the required low temperature. There was room for improvement in terms of load capacity.

[Means to solve the problem]

The present invention has been made in view of the above points, and its purpose is to make a sheet material that is a constituent material of an assembly box body inserted into a case body with a handle with a foamed synthetic resin layer on the inner surface of a paperboard layer. , and is formed from a laminated material in which an aluminum vapor-deposited layer is laminated on each of the foamed synthetic resin layers, and this sheet material includes:
A bulge is provided by bulging the foamed synthetic resin layer side of the portion corresponding to the inner surface of the box including the lid plate, and an air chamber is formed between the inner surface of the bulge and the paperboard layer. At the same time, when the sheet material is assembled into a box shape, the edges of the orthogonally adjacent bulges are brought into close contact with each other, thereby providing protection functions for the packaged items, such as cushioning properties, heat insulation properties, moisture resistance, and load resistance. To provide a packaging container which has improved properties and is convenient to carry. Also,
Another object of the present invention is to provide an improved packaging container that has a metallic luster to increase its commercial value. Therefore, the above object of the present invention is to provide side plate pieces on each side of a rectangular bottom plate, and one set of side plate pieces facing each other among these side plate pieces has their top sides facing opposite to the upper side overlapped with each other. A cover plate piece formed to a size that can fit together is provided, and a top folding piece is connected to the upper side of the opposite side plate piece of the other set via the hinge part, while the side plate piece of the adjacent side plate piece is A foamed synthetic resin layer is layered on one side of a paperboard layer, and an aluminum vapor-deposited layer is laminated and bonded on one side of a paperboard layer. The bottom plate, side plate piece, cover plate piece, top folding piece, and inner folding piece of this sheet material are formed of a laminated material, and on the bottom plate, side plate piece, cover plate piece, top folding piece, and inner folding piece, there is a part of the side plate piece where the inner folding piece is folded in half and overlaps, and the part of the side plate piece and said part. Except for one side of the inner folding piece to be joined, a bulge formed by bulging the foamed synthetic resin layer side of the sheet material is provided, and adjacent bulges among these bulges are opposite to each other. The green sides are formed so that they are in close contact with each other when the sheet material is assembled into a box shape, and
The assembly box body, in which air chambers are formed between the inner surface of each of the bulges and the paperboard layer, is formed into a cylindrical shape corresponding to the assembled product of the assembly box body. This is achieved by a packaging container that is inserted into a case with a handle.

Therefore, after storing the product in the box assembly, the case body 50 is assembled as shown in FIG.
It can be inserted and stored in a package, packaged, and sold. In this case, the box assembly may be affixed with a seal 40 at the overlapping portion of the lid plate pieces 18 and 19. In addition, as shown in FIG. 6, the lid plate piece 18 is provided with a fitting notch 32, and the other lid plate piece 19 is provided with a tongue piece 33 that fits into the notch 32, so that a seal can be used when assembling the box. You may temporarily fasten the cover plate pieces 18 and 19 without leaving the room. Further, side plate pieces 13 and 15 to which cover plate pieces 18 and 19 are connected
and the inner folding pieces 24 to 27 join the part 13
a, 15a and one side portions 24a to 27a are paperboard layer 1
It may be formed by only a, and this makes the folding operation of this part very easy. Note that the paperboard layer 1a may be art paper or cardboard made from pulp, or a composite sheet made of a foam sheet as a base material and having a paperboard layer on the surface, etc., with a certain thickness.
A flat sheet of 0.5 to 3 mm is used as the foamed synthetic resin layer 1b, and a foamed sheet of polystyrene paper, crosslinked foamed polyethylene, foamed polyethylene, etc. is used. The adhesive for the adhesive layer 1b is a thermoplastic resin with a melting point of 70 to 123°C, such as ethylene/vinyl acetate copolymer, low density polyethylene, or Surlyn (registered trademark of DuPont). Ethylene polymer films, acrylic resins, vinyl acetate resin emulsions, etc. having a thickness of 3 to 100 microns are used. The aluminum vapor deposited layer 1d is formed into a foamed synthetic resin layer 1b.
For example, aluminum may be deposited directly on the surface of the foamed synthetic resin layer 1b, or the surface of a thermoplastic resin film adhered to the surface of the foamed synthetic resin layer 1b or on the surface of the foamed synthetic resin layer 1b. Polyester or polyurethane anchor coating agent, such as Toyo Ink Manufacturing Co., Ltd.
After applying an anchor coating agent such as Underlatsuka RL (trade name) manufactured by Toyo Morton Co., Ltd. or Adcoat AD506F (trade name) manufactured by Toyo Morton Co., Ltd. at a rate of 0.03 to 5 g/ ^m2 , Perform aluminum vapor deposition. In this case, the thickness of the film is 8
~20 microns are commonly used. Further, the thickness of the aluminum vapor deposited layer is 0.025 to 0.2 micron, preferably 0.03 to 0.05 micron. At this time, blue is created by adding 0.3 to 5% by weight of pigments such as marine blue, malachite green, salmon pink, wine red, yellow lead, zinc, and yellow to the anchor coating agent. You can get green, pink, wine-colored, or golden metallic luster.

[Effect of the idea]

The present invention is as described above, and it goes without saying that the assembly box body can be easily assembled by each hinge part, and the foamed synthetic resin layer of the sheet material and almost the entire area (80% or more, preferably more than 80%) of the inner wall surface of the box can be easily assembled. The air chamber that expands over 90% of the time can effectively protect the stored items from impact, and has excellent heat insulation and cold retention functions.Also, the aluminum vapor-deposited layer provides moisture resistance. At the same time, the inner surface has a metallic luster, further increasing the commercial value of the packaging container. During assembly, the edges of the bulges that are orthogonally adjacent to each other are in close contact with each other, which improves the load-bearing capacity of the box as a whole and provides excellent shape retention. Case with Handle Since it is inserted and stored inside the body and is configured as a packaging container with a handle, the packaged items in this packaging container have a good appearance, are extremely convenient to carry, and have great practical value. is extremely large.
