Description

[Detailed description of the invention] The present invention relates to a container for storing hamburgers, etc., and more specifically, the lid part can be easily closed and opened from the storage part, and the engaging part is omitted. To provide a container which is free from the risk of breakage, which has a reinforced rim of a container part, and which can be manufactured in one piece.

Conventionally, as a container for storing hamburgers, etc., a storage part and a lid part are connected by a hinge part, for example, as disclosed in Japanese Utility Model Application Publication No. 54-145502.
An engagement method has been proposed in which an engagement hole provided on one side of the housing portion and a protrusion provided on one side of the lid portion are engaged with each other.

However, in such a container, when closing the lid part to the storage part, two operations are required: the action of closing the lid part on the top surface of the storage part, and the action of inserting the protrusion into the engagement hole. The manufacture of the container is complicated due to the provision of protrusions and engaging holes, and the container itself may be damaged during handling, which poses a problem in terms of product quality.

In view of these conventional problems, the present invention has been developed to provide a container for hamburgers, etc., in which the engaging portion does not break or break, and the rim of the accommodating portion as the engaging portion is reinforced, making it easy to engage. The purpose is to use foamed polystyrene paper with a high coefficient of friction as the material,
A fitting opening that forms a rim folded piece over the entire outer periphery of the rim of the accommodating part and that can be externally fitted to the rim folded piece of the accommodating part via a hinge part extending from one edge of the rim folded back. The main feature is that a lid portion having an edge portion is integrally connected to a housing portion.

Hereinafter, the details of the container of the present invention will be further explained based on the attached drawings.

What is shown as 1 in the figure is a housing part of the container, and the edge of the housing part 1 is extended outwardly and downwardly over the entire outer periphery of the mouth edge to form a mouth folded piece 2. , edge recesses 3 recessed toward the bottom surface are formed at appropriate locations on the top of the edge folded piece 2 (two locations in the illustrated example), and, moreover, on the surface of the edge folded piece 2, as indicated by imaginary lines in the figure. It is formed by providing an appropriate number of ribs 4 as shown.

Moreover, what is shown as 5 in the figure is the housing part 1.
It is a lid part connected via a hinge part 6 extending from the end edge of the two edge folded pieces on one side, and this lid part 5
The fitting opening edge portion is of a size that can be externally fitted onto the edge folded piece 2 of the above-mentioned housing portion 1, and has a locking step portion at the upper end of the fitting opening edge portion that engages with the top of the opening edge folded piece 2. The rim recess is formed to bulge outward through the rim folding piece 2, and the rim recess is formed so that the space inside the accommodating part 1 and the space outside can communicate from the outer surface of the rim recess 3 of the rim folded piece 2. A protrusion 7 is provided in a portion corresponding to the mouth rim by bending the inner surface from the inside of the mouth rim toward the outside so that the inner surface is spaced apart from the outer surface of the mouth rim recess 3. By fitting the protrusion 7 on the outside, ventilation from the inside of the housing section 1 to the outside is made possible.

In the container of the present invention, the lid part 5 of the storage part 1 is integrally connected to the lid part 5 of the storage part 1 through a hinge part 6 using foamed polystyrene paper having a large coefficient of friction.

Note that the edge folded piece 2 of the housing part 1 and the fitting edge part of the lid part 5 are formed so that they can be fitted to each other, and the fitted state is such that the lid part 5 is connected to the housing part 1.
In order to provide a means that can be engaged upwardly, the outer surface of the edge folded piece 2 is slightly tapered 8 upwardly.

If the upper taper 8 is applied too much, the engagement state may not be maintained due to the taper 8 even if the fitting opening edge portion of the lid portion 5 is externally fitted onto the folding piece 2. When a large upward taper 8 is provided, it is desirable that the inside size of the opening edge of the lid part 5 is large enough to tightly fit the opening flap piece 2, as shown by the imaginary line. Place the ribs 4 in the appropriate places on the edge flap piece 2 as shown.
It will be understood that when the rib 4 and the fitting edge portion of the lid portion 5 are provided, the fitting is more secure than when only the edge folded piece 2 is provided.

In addition, what is shown as 9 in the figure is a rib provided on the bottom surface of the accommodating part 1.

In the container for hamburgers or the like of the present invention as described above, the container part 1 is formed by extending the rim folded piece 2 over the entire outer periphery of the rim with the edge facing outward and downward. A fitting opening edge portion of a size that can be externally fitted onto the opening edge folding piece 2 of the housing portion 1 is connected to the upper end of the fitting opening edge portion through a hinge portion 6 extending from the edge of the opening edge folding piece 2 on one side. A container is formed by integrally connecting a lid part 5 which is formed by bulging outward through a locking step part which locks on the top of the edge folded piece 2,
Since it is made of foamed polystyrene paper with a large coefficient of friction, the edge folded piece 2 of the housing portion 1 and the fitting edge portion of the lid portion 5 form a fitting opening at the top of the edge folded piece 2. By fitting together with the locking step at the upper end of the edge portion locked, both the storage portion 1 and the lid portion 5 are attached to the edge folded piece 2.
The fitting is engaged by the elastic restoring force due to the configuration in which the edge is folded back outward and downward while leaving the edge in a free end shape, and the frictional force caused by the surface contact of the inner surface of the fitting edge portion with the outer surface of the edge folded piece 2, The engaged state extends over the entire outer periphery of the mouth edge of the container 1, and the mutually engaged state is strong, and the closing and opening of the container 1 is performed only by the outer fitting operation and the outer fitting opening operation. This not only eliminates the need for inserting the protrusion into the engagement hole as in conventional containers, but also eliminates the need for the engagement part to break or break due to the omission of the engagement part. There are no problems such as difficulty in molding the container, and it can be easily molded from expanded polystyrene paper as the container material.

In the illustrated embodiment, the lip folding piece 2 is provided with the lip recess 3, and the lid portion 5 is provided with the lip recess 3.
There is a protrusion 7 from the inside to the outside in the corresponding part.
, the space inside the container 1 and the space outside the container 1 communicate with each other between the mouth edge recess 3 and the protrusion 7 of the lid 5, allowing air to circulate. In addition, when food is stored in the container and placed in a refrigerator, etc., the space inside the container 1 and the space outside are effectively separated. This allows cold air to enter through communication, allowing for internal refrigeration.
