Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an egg container used for storing and storing chicken eggs for transportation, over-the-counter display, or storage at home in a refrigerator or the like.

[0002]

2. Description of the Related Art This type of egg container uses a sheet of a synthetic resin material having a high rigidity such as polyethylene terephthalate (PET), and a container body and a lid part which are openably and closably connected to each other via a hinge part are vacuumed. Formed integrally by molding or blow molding, so that it does not open easily with eggs stored
The flange portion provided at the peripheral portion other than the hinge portion is sealed by using a sealing means such as a stapler, heat fusion or a sealing tape.

[0003]

However, these egg containers have some problems that need to be solved. For example, the sealing means will not function once opened, so do not use a rubber band to open them. It holds and holds,
In this case, due to insufficient sealing, the egg container may be deformed when ejecting the egg and the egg may pop out and be damaged, and miscellaneous bacteria such as Salmonella spatter and adhere to other foods. I was afraid to do it.

When a synthetic resin material such as PET is used for the material of the container, these materials are not biodegradable and are flame retardant. It is not preferable for environmental protection because it does not decompose even if buried in it, and it may generate harmful gas when incinerated.

In view of the above, the present invention is an egg container capable of solving the problems of the prior art, and has a structure that enables particularly reliable sealing, so that chicken eggs can be ejected or miscellaneous bacteria such as Salmonella can be scattered and other foods can be used. Eliminates the risk of sticking to
(EN) Provided is an egg container whose main purpose is not to damage the environment even after disposal after use.

[0006]

The egg container according to the present invention comprises:
The container body has a rectangular shape and a flange portion protruding from the opening edge portion, and a lid portion, and the inner and outer surfaces are formed in a concavo-convex shape with respect to the corners of the opening edge portion where the container body and the lid portion fit. It is a structure that has a detachable locking and holding part with a mating part and a fitting receiving part.

In this egg container, since the inner and outer surfaces are deeply fitted and joined at the corners of the opening edge where the container body and the lid are fitted, a non-restoring stapler or other sealing means is used. Unlike the prior art in which a rubber band or the like is temporarily fixed after opening, it is possible to hold and hold in a reliable sealed state even during repeated use.

[0008] Therefore, since the lock-holding structure having a high sealing property does not scatter Salmonella and other miscellaneous bacteria, it can be more effectively prevented from adhering to other foods when stored in a refrigerator, etc. Since it can maintain a stable shape retention state with less heat, there is no risk of the chicken egg popping out and falling even if it is held with one hand.

Further, in the locking holding portion, the fitting receiving portion side has a fitting surface projecting inwardly to form a locking projection in an arc shape, and the fitting portion side has a concave fitting surface inward. It is possible to adopt a form in which the engaging groove is formed in an arc shape.

In this egg container, since the locking projections and the locking grooves formed in an arc shape are fitted and locked in a wide range of the corner portion, more reliable locking and holding can be performed. If there are a large number of chicken eggs to be stored, it is possible to provide locking holding portions having the same structure at intermediate positions other than the four corner portions, if necessary.

Further, by forming the locking projection and the locking groove in the shape of an arc in the corner portion, the corner portion can be reinforced and deformation of the egg container can be reduced, and for example, in a weak flange portion. As compared with the case where the locking protrusion is provided and the locking groove is provided to form the locking holding portion, a locking holding structure that is more reliable and can be repeatedly used can be obtained.

Further, the container main body and the lid portion are provided with a substantially truncated cone-shaped cushioning projection portion for cushioning adjacent chicken eggs between the egg accommodating portions, and the tip side of one cushioning projection portion and the other cushioning portion are provided. It is possible to adopt a form in which a detachable guide locking portion formed in a concavo-convex shape is provided on the tip side of the protrusion.

In this egg container, it is possible to perform accurate positioning with respect to the locking and holding portion and more reliable sealing in cooperation with the locking and holding portion. The shape retention state can be maintained.

Further, the container body and the lid portion are provided with knobs for performing a lid-opening operation on the flange portion adjacent to the locking and holding portion so that the knobs are separated from the flange surface to be joined. It is possible to form a step or to form a structure in which a flange surface to be joined is provided so as to extend in an intersecting shape in the horizontal direction so as to project.

In these egg containers, each picking piece can be easily pulled up and down by picking it with a fingertip, and particularly by adjoining to the locking holding portion, the lid opening operation can be performed with a small pulling force. it can.

The container body and the lid of the egg container may be integrally formed by connecting one side of the opening edge with a hinge so as to be openable and closable. In the case of an egg container that can improve the fitting accuracy of the protrusion and the locking groove and that stores a small number of eggs, the position where the locking holding portion is provided is 2 at the corner opposite to the hinge portion. Even a form where only one part is provided works well.

The egg container can be integrally formed of a synthetic resin material to which at least talc, an antibacterial agent, and a coloring agent containing bamboo powder are added, and the synthetic resin material is biodegradable. Can also be used.

In this egg container, by adding an antibacterial agent and bamboo powder having an antibacterial effect, salmonella bacteria and other miscellaneous bacteria do not scatter in cooperation with a highly locking and retaining structure, so that a refrigerator, etc. When it is stored in, it can be more effectively prevented from adhering to other foods, and in particular, if a biodegradable synthetic resin material is used, it can be safely disposed of without environmental damage.

Further, the container body and the lid portion of the egg container may be formed separately so as to be separable,
In this egg container, the container body and the lid may be made of the same material, but they can be made of different materials, for example, the container body is made of at least talc, an antibacterial agent, and a coloring agent containing bamboo powder. It is also possible to adopt a form in which the lid is formed of a transparent synthetic resin material as well as the added synthetic resin material.

In this egg container, since the container body contains an antibacterial agent and bamboo powder having an antibacterial action, it is possible to suppress the propagation of Salmonella and other miscellaneous bacteria, and the existing lid side. Similar to the egg container, it is made of a transparent synthetic resin material that does not use a coloring agent and a bamboo powder that has a coloring effect, so it is possible to visually confirm the remaining amount of chicken eggs without opening and It will be cheaper.

Further, both when the container body and the lid are integrated or separately, the container body and the lid are made of a transparent synthetic resin material, and along the inner surface of the container body. The interior material may be attached and the interior material may be formed of a synthetic resin material to which at least talc, an antibacterial agent, and a coloring agent containing bamboo powder are added.

In this egg container, the container body and lid are made of a synthetic resin material of the same material as the existing egg container, and the interior material has an antibacterial action. The container body and lid are inexpensive. In addition to being able to check the remaining amount of chicken eggs from the transparent lid, the antibacterial action of the interior material and the sealing property of the container body and lid holding and holding structure prevent the propagation and scattering of Salmonella and other germs. Can be prevented.
