Abstract

(57) [Summary] [PROBLEMS] A simple container in which a thin bottom plate is fused to a foamed frame material has a large bulk capacity. Improving that the transportation efficiency is extremely low because packing cannot be performed. SOLUTION: It is a folded object having a small bulk capacity, or a separated small component unit such as a frame or a bottom plate, and the component unit is transported as it is, and at a transport destination, it is particularly excellent. This is a simple food storage container 10 capable of assembling component units as they are without using assembly tools. The constituent member unit having a small bulk capacity can thereby increase the number of transfer containers by the unit transfer means, and can significantly reduce the distribution cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple disposable plastic container for storing various processed foods such as bento, sushi, and gyoza.

[0002]

2. Description of the Related Art In recent years, as such a simple plastic container, a simple container obtained by fusing a thin bottom plate to a foam frame material has been widely used because of its good appearance and excellent strength for its structure. It became so. After that, various improvements in bonding strength and sealability have been made, and the use has been extended to various kinds of juices, and the demand has been further increased.

[0003] However, the simple container having such a structure has a large bulk capacity, requires a large space when it is carried out from the manufacturing place, and has a low multi-pressure resistance strength, so that unreasonable packing cannot be performed. Is low.

[0004] For this reason, a container in which the height of a frame material for defining the bulk capacity of a completed container is reduced has been disclosed above.

[0005] However, even in the case of a completed container having a reduced bulk capacity, an occupancy of only several% of the transfer capacity of the transfer means such as a transfer truck can be obtained, and the transfer efficiency and, consequently, the distribution efficiency are essential. It does not lead to any improvement.

[0006]

The problem to be solved in the present invention is to establish a fundamental improvement measure for improving the transport efficiency of a simple bulky food storage container composed of a frame material and a bottom plate. is there.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a component unit having a small bulk capacity itself is used, the component unit is transported as it is, and a special assembly tool is used at a transport destination. This is a simple food storage container that can be assembled as it is without any components.

[0008] The component members having a small bulk capacity may be folded as a whole, or may be separated small component units such as a bottom member and a frame that constitute a simple container. The number of transport containers by means can be increased, and the distribution cost can be significantly reduced.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to assemble a folded container or each constituent member unit without using special assembling tools at a transport destination, it is necessary to use a simple adhesive with each separated constituent member unit. Or a structure that can be assembled without using any adhesive.

[0010] As a structure for this purpose, the bottom plate has a shape in which an edge is raised from a thin plastic plate by press molding, and the upper end thereof is bent so as to embrace the upper end surface of the frame material.

Then, at the place where the processed food is packed in the simple container, the bottom plate is dropped into the inside of the frame material, and the upper end of the raised bottom plate is fitted to the upper end surface of the frame material to easily form the simple container. Can be assembled.

In order to prevent the constituent members of the container assembled in this way from coming off from each other, it is necessary to provide a concave-convex locking means or a locking means using an adhesive on each member. it can.

Further, in assembling the simple container, the appearance of the assembled container can be improved by providing a cutout in the frame material into which the bent portion at the top of the rising portion of the bottom plate enters.

The frame material used in the present invention is not limited to foamed plastics, but may be thick paper having a width of about 3 mm to 5 mm,
Recycled paper, synthetic wood, etc. can be used arbitrarily.

[0015]

1 and 2 show a molded bottom plate 1 and a foldable frame member 2 as constituent members obtained by separating a simple container in the present invention, respectively. A large number of molded bottom plates 1 and folding frame members 2 which are component units of a simple container can be transported in a state of being overlapped with each other, and can be transported several tens times as many as the conventional assembled simple container.

FIGS. 3 and 4 show the A-type of FIGS. 1 and 2, respectively.
2 shows a cross section of the molded bottom plate 1 and the frame member 2 as viewed from the line A and the line BB. In FIG. 3 showing a cross section of the molded bottom plate 1, reference numeral 11 denotes a rise formed on the outer edge of the bottom portion 12, and at the top portion, it is bent downward from outside to form a hanging portion 13, and , A fitting concave portion 14 with the frame material is provided. Reference numeral 15 denotes an engagement protrusion provided on the upper inner surface of the rising 11. Further, as shown in FIG. 4 showing a cross section of the frame member 2, a notch 21 is provided above the outer surface of the frame member 2 to insert the rising and falling portion 13 of the molded bottom plate 1, and above the inner surface thereof, The engaging projection 15 of the molded bottom plate 1 shown in FIG.
Is provided with an engaging concave portion 22 that engages with the first concave portion.

At the assembly site where each component member has been transported, the simple container 10 shown in FIG. 5 can be obtained simply by dropping the molded bottom plate 1 into the frame member 2.
As shown in FIG. 5, in a state where the formed bottom plate 1 is dropped into the frame material 2, the rising portion 13 of the rising of the formed bottom plate is attached to the frame material as shown in FIG. The hanging portion 13 does not protrude into the outer surface of the assembled simple container by entering the notch 21 provided, and the appearance of the container can be kept clean. Further, the engaging projection 15 provided at the rising of the molded bottom plate is inserted and seated in the engaging recess 22 provided above the outer surface of the frame member 2,
After assembly, the assembled container does not disassemble.

Further, instead of or in addition to this engaging mechanism, the adhesive 3 attached to the bottom surface of the fitting concave portion 14 provided at the rising of the molded bottom plate can provide a stronger assembly state. You can get.

The present invention is not limited to this embodiment, and various changes can be made within the scope of the invention.

[0020]

【The invention's effect】

(1) Since it is easy to assemble at the food storage site, it is not necessary to prepare many bulky completed simple containers, and the effective use space at the site can be expanded.

(2) Since there is no bulk at the time of transportation, the transportation efficiency can be remarkably improved.
