Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an egg container formed by swelling a generally known synthetic resin sheet material, and it is easy to open and reclose the container after opening. The present invention relates to an egg container capable of maintaining a closed state when stored in a refrigerator even after opening.

[0002]

2. Description of the Related Art A conventional egg container formed by bulging such a synthetic resin sheet material is, as is generally known, a container in which a plurality of egg receiving recesses having a depth capable of accommodating the lower half of the egg are arranged. The main body and a lid formed by arranging a plurality of egg storage recesses having a depth that can store the upper half of the egg are molded in a series, and the boundary between the container main body and the lid is a bent portion. . In the method of packaging eggs, the eggs were stored in the eggs receiving recesses of the container body, the product label was placed on the eggs, and then the lid was folded at the bent portion and covered from above the container body, and overlapped. The outer peripheral edge of the container body and the outer peripheral edge of the lid are closed with an adhesive tape or a stapler and closed.

[0003]

The eggs purchased in the above-mentioned packaged state are usually opened by removing the adhesive tape or the stapler, and the taken-out eggs are stored in a predetermined storage place in the refrigerator. However, it has recently been confirmed that chicken eggs may be contaminated with bacteria such as Salmonella, and that storing such contaminated chicken eggs in a refrigerator is stored in the same refrigerator. There was the disadvantage that contamination could spread to other foods. In such a case, the eggs may be stored in the refrigerator with the eggs still in the packaging container, but once the packaging container is opened, the elasticity of the bent portion naturally causes the lid to be in the open state, and this is again required to be in the closed state. Had a problem to solve that had to be stuck with adhesive tape or stapled or rubber banded.

The present inventor has devised a simple temporary fixing means which has a form which does not obstruct the product even at the product sales stage, which allows the lid to be easily opened and closed after the lid is opened, and which can maintain the reclosed state. By opening the lid and storing the remaining eggs in the refrigerator with the lid still closed in the packaging container, it is possible to increase bacterial contamination in the refrigerator and prevent contamination from surroundings. It is intended to provide a chicken egg packaging container.

[0005]

The structure of the egg container for achieving the above object will be described with reference to the reference numerals shown in the drawings showing the structure of the embodiment. , 21 are formed on at least a part of the container body 1 and the lid 2, and the container body 1 and the lid 2 are integrally connected to each other via the intermediate bent portion 4, The egg housing recesses 11 and 12 of the lid 2 or the container main body 1 projecting outward from part or all of the outer peripheral edge of the main body 1 or the lid 2 and facing each other in the closed posture of the container.
1 is provided with a protruding body 3 having a superposed concave portion 31 formed on the outer surface thereof.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In carrying out the present invention,
The container body 1 and the lid 2 are made of a synthetic resin sheet, and given a predetermined shape by blow molding as in the related art.
Any type of synthetic resin sheet can be used as long as it is a sheet material conventionally used for such containers. However, if the synthetic resin sheet is made of PET (polyethylene terephthalate) resin, waste material recycling In addition, since the calorific value is small even in the case of incineration, the life of the incinerator can be extended, and the generation of harmful substances such as dioxin can be prevented to solve the problem of pollution.

A projection 3 serving as an engagement portion for temporarily fixing the container main body 1 and the lid 2 for maintaining the closed state is integrally formed with the container main body 1 or the lid 2 and is integrally formed. Or, it protrudes outward from part or all of the outer peripheral edges 12 and 22 of the lid 2. The protruding body 3 has an egg housing recess 1.
A superimposed concave portion 31 is formed on the outer surfaces of the egg accommodating portions 11, 21.
Or a shape that can include 21 or approximately the same shape,
What is necessary is just to make it the shape which at least one part of the recessed wall surface overlaps closely when superposed. The connecting portion 5 between the protruding body 3 and the outer peripheral edges 12 and 22 of the container body 1 or the lid 2 is folded when the lid is closed, so that the connecting portion 5 can be easily bent, and the egg housing recesses 11 and 21 can be formed. In order to prevent the lid from being difficult to maintain due to its elasticity when polymerized on the outer surface,
It is desirable to provide a bending line in which perforations, cut lines, long holes and the like are continuously formed, or to take measures such as bending in advance into a concave groove shape.

The projecting body 3 is formed on both sides or one side of the container body 1, the outside of the container body 1, both sides of the lid 2, or one side of the lid 2, At least one or more locations such as the outside can be provided continuously with the outer peripheral edge of each location. Next, as the shape of the protruding body 3, one or two, more than one, or a plurality of overlapping concave portions 31 are continuously or
Any shape may be used, such as a shape provided by dividing each one.

Although the structure is not always required, when the projecting body 3 is overlapped with the lid 2 at the time of re-closing the lid, the overlapping state is caused by the remaining elasticity of the connecting portion 5. It is desirable to provide a lock mechanism in order to eliminate the possibility that maintenance becomes difficult and stably maintain the reclosed state. For this purpose, the inclined portion 33 of the partitioning column of the overlapping concave portion 31 of the projection 3
Alternatively, a small projection 32 is formed on the partition wall 34, while the egg-receiving recess 21 of the lid 2 or the egg-receiving recess 11 of the container body 1 on which the small projection 32 is formed. A small projection 23 or a small projection 13 that fits into and engages with the small projection 32 at the time of stacking may be provided on the inclined surfaces 24, 14 or the partition walls 25, 15 of the partition column corresponding to the above. Further, as a product sales form, the container main body 1 and the lid 2 are sealed by using a stapler or an adhesive tape, welding, or the like, and the projection 3 is put thereon from above to close the lid.
Alternatively, it goes without saying that the container body 1, the lid 2 and the protrusion 3 may be set in a closed state, and these three members may be sealed in one step.

[0010] In the egg container of the embodiment described above, when the lid is closed again after purchase, the protruding body 3 is connected to the lid 2 or the container body 1.
The lid 2 is easily temporarily fixed to the container body 1 simply by superposing it on one of the above and polymerizing, so that the lid 2 is maintained in a closed state, and the eggs are stored in a refrigerator with the eggs therein.
Therefore, it has the effect of preventing the propagation of Salmonella in the refrigerator, and in particular, preventing the contamination of other foods. Further, since re-closing is extremely easy, bulkiness due to opening of the lid is eliminated, and a means for re-closing which was conventionally required is not required. In addition, it has a form that does not interfere with the product sales form.
