Description

[Detailed description of the invention] <Industrial application field> This invention relates to a packaging container for dumplings, etc. for take-out or display.

<Conventional technology and the problems to be solved by the invention> Conventionally, folding box-shaped containers made of paper or thin synthetic resin sheets have been mainly used for packaging containers for take-out items such as dumplings. However, the assembly work is troublesome, and the container deforms when a part of the container is held while storing dumplings etc.
There were disadvantages such as shape deformation and cracking of the dumplings.

Furthermore, the above-mentioned containers are not suitable for use as display containers in stores due to their appearance and other aspects.
There was a demand for a container that could be used both for take-out and for display.

The purpose of this invention is to provide a device that can store dumplings and the like in a good-looking manner, can be used for both take-out and display purposes, has excellent shape-retaining effects, and is easy to manufacture.

<Means for Solving the Problems> In order to achieve the above object, the packaging container for dumplings, etc. of this invention has an elastic brim-like folded part with a sharp edge shape at the lower end formed on the opening edge. An inner container made of a non-foamed synthetic resin sheet is formed by bending a foamed resin sheet, and a vertical inner peripheral wall and a frame-shaped peripheral edge on the upper surface are integrally formed, and the interval between the edges is The circumferential frame having an inner circumferential wall interval smaller than the inner circumferential wall interval is assembled so as to fit over the lid, and the flange-like folded part on the opening edge of the inner container is formed so that when the circumferential frame is covered, the upper is formed so as to elastically abut against the frame-shaped periphery of the circumferential frame, and the sharp edge portion at the lower tip of the folded portion also elastically and closely abuts against the inner circumferential wall portion of the circumferential frame. It is characterized in that it is formed so as to come into contact with each other in the state.

<Function> According to the packaging container for dumplings and the like having the above structure, when the circumferential frame is covered, the upper part of the folded part is attached to the frame-shaped periphery of the circumferential frame, and the edge part of the lower end of the folded part is attached to the frame-like edge of the circumferential frame. Since they come into contact with the inner circumferential wall portions in a tightly elastic state, the circumferential frame is prevented from deforming at the folded portions, and the elastic effect of the folded portions ensures a secure fit to the inner container. Furthermore, since the inner container is made of a non-foamed synthetic resin sheet and the peripheral frame is made of a foamed resin sheet, the contact between the edge portion and the peripheral frame is less than that of a hard non-foamed resin sheet. This makes contact with the foamed resin sheet, which is soft and has a large coefficient of friction, resulting in a more secure fitted state.

<Examples> Examples will be described in detail below with reference to the accompanying drawings showing examples.

Reference numeral 1 denotes an inner container formed by vacuum forming or pressure forming a non-foaming synthetic resin sheet such as polystyrene, and has a shallow container shape suitable for storing dumplings a, etc., and has an opening edge 10. A folded portion 10' is formed in the shape of a brim. In addition, the inner container 1
Rib-shaped partitions 12 are provided at predetermined intervals on the bottom surface 11 of the
are bulged, and partial protrusions 13 are formed between the partitions 12. Partition 12 above
The projections 13 can effectively prevent the stored dumplings a from shifting, and the partition 12 can ensure sufficient strength of the bottom surface 11. Furthermore, rib-shaped reinforcing portions 15 are formed at several locations on the long sides of the inner container 1, extending from the circumferential side 14 to the bottom surface 11 toward the storage side, ensuring shape retention between the circumferential side 14 and the bottom surface 11. has been done.

Reference numeral 2 denotes a peripheral side frame formed by bending a foamed resin sheet such as foamed polystyrene.
It is formed to have an inner wall interval smaller than the interval between the edges of the inner container 1, and is assembled so as to fit over the inner container 1 like a lid. That is, the circumferential frame 2 has a folded portion 10' of the inner container opening edge 10.
The upper part of the folded part 10' is in elastic contact with the frame-shaped periphery 21 of the circumferential frame 2, which will be described later, and the deformation of the circumferential frame 2 itself is also caused by the folded part. It is blocked at 10',
A secure mating condition is ensured that will not accidentally come off. Moreover, the edge b portion formed by trimming at the lower end of the folded portion 10' of the inner container 1 is also in contact with the inner peripheral wall 20 portion of the peripheral side frame 2, and the contact between the two is also made of hard non-foamed resin. The fact that the sheet is in contact with the foamed resin sheet, which is relatively soft and has a large coefficient of friction, results in a more reliable fitted state (see especially FIG. 4). Therefore, when transporting or stacking the above-mentioned containers that have not yet contained contents, it is possible to lift them by simply grasping the peripheral frame 2 without placing your hand on the inner container 1. It becomes easy to handle.

Further, on the upper surface of the peripheral frame 2, a frame-shaped peripheral edge 21 is provided so as to cover the opening edge 10 of the inner container 1.
The structure is such that the thick part of the material is not exposed on the upper end surface of the peripheral frame 2, ensuring a good appearance, and the frame shape allows for the appearance of dumplings a etc. It can also be used for storage purposes.
Furthermore, it is also possible to display the type of stored item, container, trademark, etc. on the peripheral edge 21 portion. Furthermore, a thin material c such as a synthetic resin film printed with various patterns is laminated on the outer surface of the circumferential frame 2 (see FIG. 4), giving it an even more beautiful appearance.

The above-mentioned peripheral frame 2 is made of a belt-shaped sheet material S with the thin body c laminated on one side, which is the outer surface.
A V-shaped bending groove 22 is formed by leaving at least the thin body c at a predetermined location that will become a corner, and the peripheral edge 21 is
A protruding piece 21' and a V-groove 24 for bending the protruding piece 21' are formed, and the pieces are bent at right angles at each bending groove 22, and the obliquely cut ends 23 are brought together and heat fused. Alternatively, the projecting piece 21' may be bent inward at right angles to form the peripheral edge 21 after being bonded with adhesive and framed. (See Figures 6 and 7).

Note that the inner container 1 has a partition 12 on the bottom thereof.
In some cases, a larger number of protrusions 13 and the like may be formed. Further, the peripheral frame 2 may be formed of a single layer of foamed resin sheet having at least a skin layer on the outer surface side without laminating the thin body c, and even in this case, a sheet with a pattern printed on the surface may be used. This will ensure a good appearance.

Furthermore, as a material for forming the peripheral frame 2, in addition to the above-mentioned expanded polystyrene, polyethylene,
Foamed sheets made of various resins such as polypropylene can be used.

According to the packaging container for dumplings, etc. of this invention constructed as described above, the flange-shaped folded portion 10' formed on the opening edge 10 of the inner container 1 is such that when the peripheral frame 2 is covered, the upper part The frame-shaped peripheral edge 21 of the peripheral frame 2 is formed so as to come into contact with the frame-shaped peripheral edge 21 in an elastically tight state, and the sharp edge b at the lower tip of the brim-shaped folded part 10' also has an interval between the edges b. Since it is provided so as to be in elastic contact with the inner circumferential wall portion 20 of the circumferential frame 2 which is formed to have an inner circumferential wall interval smaller than the inner circumferential wall interval dimension,
The circumferential frame 2 is prevented from being deformed by the folded portion 10', ensuring good shape retention, and is assembled to the inner container 1 with good integrity due to the elastic effect of the folded portion 10'. As a result, the inner container 1 and the peripheral frame 2 will not accidentally come off during transportation or other handling, making handling very easy. Further, the contact between the edge b and the peripheral frame 2 is made by a hard non-foamed resin sheet and a relatively soft foamed resin sheet having a large coefficient of friction, resulting in a more secure fitted state. In addition, the combination of the inner container 1 and the peripheral frame 2 ensures overall strength, and even when a portion of the container is grasped, it does not deform as in the conventional container described above, and the stored dumplings a etc. This makes it possible to eliminate conventional problems such as shape deformation and cracking.

In addition, since the peripheral frame 2 has a frame-shaped peripheral edge 21 formed on the upper surface, it is possible to store dumplings etc. in a good manner, and the thick part of the material is not exposed on the surface, so the appearance is better. Become something.

Furthermore, not only can it be used as a take-home container in wrap packaging, but the open top makes it easy to inspect stored items, and it can also be used as a display container. . Moreover, since the items to be stored can be provided by simply attaching the peripheral frame 2 after placing the items in the inner container 1, there is no need for troublesome assembly work at the site of use, and dumplings, etc. can be stored easily and efficiently. become.

Moreover, the cost is low, and it is particularly suitable as a packaging container for gyoza, shiyu mai, Chinese steamed buns, various Japanese sweets, and the like.

<Effects of the invention> As described above, according to the packaging container for dumplings, etc. of this invention, when covering the circumferential frame, the upper part of the folded part is attached to the frame-shaped periphery of the circumferential frame, and the edge of the lower end of the folded part is attached to the frame-shaped periphery of the circumferential frame. The parts are elastically in close contact with the inner peripheral wall of the peripheral frame, so that deformation of the peripheral frame is prevented by the folded parts, and the elastic effect of the folded parts makes it securely attached to the inner container. It ensures a good mating condition and is assembled with good integrity, and
Since the inner container is made of a non-foamed synthetic resin sheet and the peripheral frame is a foamed resin sheet, the contact between the edge portion and the peripheral frame is made of a hard non-foamed resin sheet and a foamed resin sheet that is relatively soft and has a large coefficient of friction. This makes contact with the resin sheet, resulting in a more secure fit and better integrity, and prevents the inner container and peripheral frame from accidentally coming off during transportation or other handling. , it can be handled very easily, and moreover, it can be provided by simply attaching the peripheral frame after placing the stored items in the inner container, so there is no need for troublesome assembly work at the site of use. , can easily and efficiently store dumplings, etc.
Furthermore, since a frame-like periphery is formed on the top surface of the peripheral frame, it has the unique effect of being able to store dumplings etc. in a good-looking manner, and also being able to be used as a take-out container by wrapping it in a wrap. .
