Summary of the Invention

Problems to be Solved by the Invention

[0006] In the method of storing the contents in a freezer or the like after putting food or other contents into a conventional container and then sealing the container with a wrap film, the volume of the container means that the storage space of the freezer or the like cannot be fully utilized. In addition, when reusing a container, it is time-consuming to wash the container after use, and detergent must be used and discharged. When a container is discarded without being reused, there are problems in that the cost of the container is significantly increased and the amount of waste is large.

[0007] On the other hand, when packaging food using only conventional plastic wrap, there are problems such as the food (such as rice balls) losing their shape due to the low strength of the bottom part, and it being difficult to stably package foods with separate ingredients (such as ginger pork).

[0008] The present invention is to provide a seal and wrap film that allows for better packaging of food products. [Means for solving the problem]

[0009] The sticker according to the first aspect of the present invention is formed in a sheet shape, one surface of which serves as an adhesive surface, and is formed with a folding portion for folding the edge portion.

[0010] In the seal of the present invention, a recess is formed by folding the edge portion.

[0011] Preferably, in the seal according to the present invention, a wrap film is adhered to the adhesive surface, and with food placed in the recess, the food can be wrapped in the wrap film.

[0012] The wrap film according to the second aspect of the present invention has the seal of the present invention attached thereto by means of the adhesive surface of the seal of the present invention. Effect of the Invention

[0013] The seal and wrap film of the present invention allows for better packaging of food. [Brief description of the drawings]

[0027] <How to use the sticker> When using the sticker 11, first, the backing paper 12 is peeled off from the back side of the sticker product 1, leaving the adhesive surface of the sticker 11 exposed.

[0028] Next, a commercially available wrap film made of vinylidene chloride resin is cut into a square shape to prepare the wrap film 3 shown in FIG. 2(a). A seal 11 is adhered to the wrap film 3 to form the wrap film 2 with a seal.

[0029] Next, side wall portions 11b, 11c, 11d, and 11e, which form the edges of seal 11, are folded along folding portion 11f toward the adhesive surface to form recess 13 as shown in FIG. 2(b) with wrap film 3 attached to the adhesive surface side. Food such as ginger pork is placed in recess 13, and the upper side of recess 13 is wrapped with wrap film 3.

[0030] As a result, the food is packaged in the sealable wrap film 2 as shown in Fig. 2(b). The food packaged in the sealable wrap film 2 is stored in a freezer, a refrigerator, or the like for storage.

[0031] <Configuration and Effects of the First Embodiment> The configuration and effects of the first embodiment of the present invention will be summarized below. The seal 11 is formed in a sheet shape, one side of which is an adhesive surface, and a folding portion 11f is formed for folding the edge portion (side wall portions 11b, 11c, 11d, 11e), and a recess 13 is formed on the adhesive surface side by folding the edge portion.

[0032] The seal 11 is formed in a sheet shape, one side of which is an adhesive surface, and a folding portion 11f is formed for folding the edge portion (side wall portions 11b, 11c, 11d, 11e) toward the adhesive surface, and by folding the edge portion toward the adhesive surface, a recess 13 is formed on the adhesive surface side.

[0033] In addition, a wrap film 3 is adhered to the adhesive surface of the seal 11, and with food placed in the recess 13, the food can be wrapped in the wrap film 3.

[0034] The wrap film 3 has the sticker 11 attached via its adhesive surface.

[0035] According to the seal 11 and wrap film 3 of the first embodiment, the folded seal 11 acts as a plate, preventing the food (e.g., rice ball) from losing its shape, and packaging is easy even for food with loose ingredients such as ginger pork, and the small packaging volume makes it possible to effectively utilize storage space in freezers, refrigerators, etc. Furthermore, after use, the seal 11 and wrap film 3 are easy to dispose of, and the amount and cost of waste can be reduced compared to conventional containers.

[0036] Therefore, the seal 11 and wrap film 3 of the first embodiment allow for better packaging of food.

[0037] In the first embodiment shown in Figures 1 and 2, the seal 11 has an edge portion (side wall portions 11b, 11c, 11d, and 11e) folded toward the adhesive surface to form a recess 13 on the adhesive surface side, but the edge portion may be folded toward the opposite side of the adhesive surface to form a recess for storing food on the opposite side of the adhesive surface.

[0038] <Second embodiment> FIG. 3 is an explanatory diagram showing a sticker according to a second embodiment of the present invention, and is a front view showing an enlarged upper left corner of the sticker product.

[0039] In FIG. 3, a seal product 101 according to a second embodiment of the present invention is a more suitable embodiment than the first embodiment shown in FIG. 1 and FIG. The sticker product 101 has a sticker 111 on the front side.

[0040] The sticker 111 is a sheet of paper with a decorative surface on the front side and an adhesive surface on the back side. A backing paper with weak adhesive strength is attached to the adhesive surface.

[0041] The seal 111 has a rectangular bottom surface 111a with rounded corners. A pair of long sides of the bottom surface 111a are connected to a long band-shaped side wall portion 111b (the lower side is not shown). A pair of short sides of the bottom surface 111a are connected to a short band-shaped side wall portion 111d (the right side is not shown).
