Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a paper foldable container suitable for storing foods such as bread, cake and the like used for baking, steaming, etc. by putting food dough such as bread, cake and confectionery, and for storing prepared foods.

[0002]

[Prior art]

 Conventionally, as this type of paper pleated container, for example, there is a container described in Japanese Utility Model Publication No. 7-6782.

[0003] In this conventional technique, a film made of polyethylene terephthalate, which is usually called PET, that is, polyester, is attached to thin paper, and the thin paper and the PET film are pressed at least partially with the bottom by press molding. It is a baking pan made of PET film and formed into a dish that becomes the inner surface of thin paper, and a container for storing prepared foods.

[0004]

[Problems to be solved by the invention]

 In this conventional example, since all of the container side plates have a single-sheet structure, the container is weak against external force, and since there is no gripping piece, it is difficult to carry a container containing foods, especially a container containing hot contents. Has the essential problem that it cannot be carried.

[0005] Apart from this conventional example, a bottom plate, a side plate formed with folds integral with the bottom plate, and a flange uniformly connected to the upper portion of the side plate as disclosed in Japanese Utility Model Application Laid-Open No. 64-2731. Containers for baked foods, such as baked confectionery, in which a flat ring fitted to the outside of a side plate of the cup is attached to the lower surface of the above-mentioned flange, are also known.

[0006] Therefore, in this conventional apparatus, when an outward horizontal ring-shaped collar is uniformly provided continuously on the upper side of a vertically folded pleated container body called a side plate, the entire circumference of the container body is inherently vertically pleated. In order to form a beautiful outer flange by bending evenly against the strong rigidity of this flange, this flange bending work is extremely difficult, and the paper may break during the flange bending. It is not possible to automate the bending process and draw a disc-shaped blank made by cutting a sheet into a circular shape to obtain a paper container with vertical folds. However, there is also a problem that paper use efficiency is poor.

[0007] Further, in each of the conventional example and the above-described conventional example, 5 to 10 sheets of paper are superimposed and sandwiched between male and female molding dies in a bevel gear shape and press-molded. Since the vertical separators are tightly engaged with each other when separating them from the container stack, it is extremely difficult to separate the individual products from each other, greatly impeding workability. There is also a common problem.

[0008] This invention automates press forming of a vertical pleated container by integrally protruding a gripping piece at the opening edge of the body of a vertical pleated container made by drawing and press-forming paper. At the same time, eliminating waste from blanking container blanks from square paper, increasing the efficiency of paper use, and making it easier to carry paper containers containing hot items to other places. The purpose is to make it easy to separate the container from the pile.

[0009]

[Means for Solving the Problems]

 The object of the invention described above is to form a paper container in which a container body having a large number of vertical folds around the bottom of the container is formed integrally with a sheet of paper, and a pair of grips is formed on an opening edge of the container body. This was achieved by projecting the pieces integrally.

[0010]

[Embodiment of the invention]

 Embodiments will be described with reference to the drawings. First, the basic structure of the present invention is as shown in FIG. 2, a sheet of paper having a high rigidity such as a kneaded paper made of silicone resin or PET, that is, a sheet 1 laminated with a plastic such as polyethylene terephthalate or polypropylene. In making a paper container 5 in which a container body 4 having a large number of vertical folds 3 around a container bottom 2 as shown in FIG. 1 is integrally formed in an upright manner, a pair of grips are formed on an opening edge 4a of the container body 4. The piece 6 is integrally protruded.

That is, the portion to be the gripping piece 6 is formed from a well-known pair of male and female from a container forming blank 1 a having a gripping piece protrusion 6 a die-cut toward the corner of the square sheet 1 as shown in FIG. A pair of gripping pieces 6 projecting partially from an opening edge 4a of a container body 4 having a large number of vertical folds 3 around the container bottom 2 as shown in FIG. Thus, the vertically folded paper container 5 according to the present invention was obtained.

Therefore, even if a hot thing is placed in the paper container 5 according to the present invention, the paper has a higher thermal insulation property than metal or the like, so that the gripping piece 6 does not become hot and the two gripping pieces facing each other. 6 can be carried safely and easily with both hands, and the container can be easily separated by picking the gripping pieces 6 with fingers or the like from the pile of paper containers with many vertical folds. I can do it.

[0013]

【Example】

 The planar shape of the bottom plate 1 in the present invention is not limited to a circular shape as shown in each figure, but may be an elliptical shape, a polygon such as a square or a hexagon, or the like. The container of the present invention can be a considerably deep (or shallow) paper container 5 as shown in FIG. 3 or 4, and the gripping piece 6 can be made as shown in FIG. It may be bent horizontally to form a horizontal gripping piece 6.

Further, the paper sheet for producing the paper container according to the present invention is obtained by coating or laminating a heat-sealable synthetic resin thin film having no problem on food hygiene on one or both sides thereof, ie, a polylaminate sheet 1. By using the paper container 5, the strength against the external force of the paper container 5 is increased, and even if a liquid is put into the paper container 5 according to the present invention, the periphery of the container bottom 2 is folded up to become the container body 4. As a result, there was no liquid leakage, and therefore, foods and beverages could be put in the container according to the present invention and cooked.

[0015]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. A paper container 5 is formed by integrally forming a container body 4 having a large number of vertical folds 3 around a container bottom 2 with a sheet 1, and a pair of gripping pieces 6 are formed on an opening edge 4 a of the container body 4. Since the container is partially integrally protruded, it is only necessary to pull out the containers one by one while holding the gripping piece 6 in order to separate the containers one by one from the stacked body of a large number of containers. Even if a hot thing is put into the container according to the present invention surrounded by the bottom part 2 and the body part 4, the gripping piece 6 does not become hot because the paper has a large heat insulating property. The paper container 5 can be easily carried with both hands by means of a pair of gripping pieces 6, and the gripping piece 6 is formed by using a blank 1a cut out as a gripping piece projection 6a toward the corner of the rectangular sheet 1. As a result, it was possible to form a single piece at the opening edge 4a of the torso, eliminating waste of paper material and efficiently removing the material. With wear, press molding process of vertical pleated paper container 5 can be automated, there are many advantages that can be inexpensively in large quantities provide quality uniform product.

According to the second aspect of the present invention, the gripping piece 6 of the container is horizontally protruded horizontally, so that the stability of the hand-held state is increased, and the effect of being convenient because it can be held in a hand pot type has been added. .

According to the inventions of claims 3 and 4, since the rigidity of the whole container is large, even if a heavy object such as water is stored in the container, the deformation of the container is reduced when the container is transported. This has the added effect of being safe to carry and of preventing food from sticking to the inside of the container when the food in the container is heated.
