DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hen egg container obtained by bulging a generally known synthetic resin sheet material, wherein an upper wall of a lid has a flat surface for attaching a product display label. The present invention relates to an egg container that can minimize damage to eggs during the distribution process.

[0002]

2. Description of the Related Art An example of a conventional egg container formed by bulging a synthetic resin sheet material will be described with reference to FIG. The bent portion 4 is composed of a container body 10 in which a plurality of egg storage recesses 11 having a depth capable of being stored are formed side by side, and a lid 20 in which a egg storage recess 21 having a depth capable of storing substantially the upper half of the egg is formed. It is molded as a series through. The support body 23 is formed on the lid 20 to separate the eggs from the upper wall 26 inwardly.
Reference numeral 6 denotes a substantially flat surface for attaching the product display label, and after covering the chicken eggs, the lid 20 is bent at the bent portion 4 and covered from above the container main body 10 to cover the container main body and the overlapping container main body. The outer peripheral edge of each lid is closed with an adhesive tape or a stapler and closed. Thereafter, the upper wall 26 or the upper wall 2 of the lid 20 having a substantially flat surface is formed.
The packaging is completed by attaching a product display label to the cover 6 and the longitudinal side walls 24 and 25 of the lid.

[0003]

The eggs to be shipped in the above-mentioned packaged state are provided inside the container with the support 2 of the lid 20.
3 and the column 13 of the container body 10 formed for the same purpose, and should not be damaged by touching each other. 23, and the strut 23 is only positioned diagonally with respect to the eggs, and there is no part having a barrier function to separate the eggs located next to each other. Actually, the side wall of the container is distorted by vibration or impact. There is a problem to be solved that chicken eggs may collide and break. Although not shown in the drawings, in the egg container formed by bulging, there is a container having a lid having substantially the same shape as the container body 10 shown in FIG. 13 in addition to the container shown in FIG. In such a container, it is necessary to enclose the product display label inside at the time of packaging, and there is a disadvantage that the product display label is finely bent at the time of closing the lid, making it difficult to identify, and does not meet the purpose of attaching the product display label externally. It was a shaped container.

Accordingly, the present inventor has developed a chicken egg packaging container which can attach a commodity label to the outer surface of the lid of the container and also can prevent the eggs from being hit and broken after packaging to a minimum. The purpose is to provide.

[0005]

The configuration of a chicken egg packaging container for achieving the above object will be described with reference to the same reference numerals as in the drawings showing the embodiments. The chicken egg packaging container of the present invention is made of synthetic resin. One side of the container body 1 is formed by bulging and forming a sheet material, and is formed by arranging a plurality of egg accommodation recesses 11 having a depth capable of accommodating the lower half of the egg, and the lid 2 covering the upper half of the egg. Are formed in a series through the bent portion 4 of the upper surface, and are formed inward on an upper wall 26 in which almost the entire surface of the lid 2 is a substantially flat surface. A step 22 for separating the eggs from each other is formed between the side wall 23 and either the side wall 24 or 25 on the side of the bent portion 4 or the open end, and when the lid is closed, almost the entire surface of the upper wall 26 and the step Substantially all over the side wall on which 22 is formed
Is formed in a fine uneven shape, and the portion having the fine uneven shape is formed.
Substantially flat surfaces of the product label sticking is provided above.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In carrying out the present invention,
The container main body 1 and the lid 2 are made of a synthetic resin sheet, and given a predetermined shape by vacuum forming or pressure forming as in the related art. As the synthetic resin sheet, any kind of sheet material conventionally used for such a container can be used.
When T (polyethylene terephthalate) resin is used, waste materials can be recycled, and even when incinerated, the calorific value is small, extending the life of incinerators and preventing the generation of harmful substances such as dioxins, thereby preventing pollution. It can deal with a solution.

[0007] In the packaged state, the step portion 22 for separating the eggs from each other includes a column 23 protruding inward from an upper wall 26 of the lid, a side wall 24 on the open end side or a side wall 25 on the bent portion 4 side. Is formed so as to keep a constant width from the strut to the side wall sufficient to separate the eggs from each other. The reason for this is that the flatness of the upper wall 26, the side wall 24 and the side wall 25 is not impaired as much as possible, so that the step 22 has a curved surface along the side of the egg or the container body between the column and each side wall. It does not have a polygonal surface as seen on the side wall of the first. Also, the height of the step 22 from the upper wall 26 of the container lid 2 is appropriately about half the depth of the lid 2, and if it is low, the function of positioning the eggs is deteriorated, and the presence of the step is reduced. It becomes meaningless, and conversely, if the height is increased closer to the depth of the lid 2, the rigidity of the lid decreases.

After the eggs are stored, the lid is closed, and almost the entire upper wall 26 of the lid 2 which is substantially flat, and substantially the entire side wall on the side where the step 22 is formed are formed in fine irregularities. And this
Packaging by adhering the product display label 3 on a fine fine uneven and are portions of the ends. The rigidity of the attached product display label 3 is imparted, the flexibility of the lid caused by the formation of the step 22 is canceled, and the strength of the step connecting the support and the side wall is added. The overall rigidity of the container lid is increased, and the collision between the eggs, which is the original purpose, is prevented, so that the effect of improving the reliability of the product is obtained.

The present invention can be implemented by appropriately modifying it within the range of achieving the object and having the following effects.

[0013]

As is clear from the above description, the present invention relates to a chicken egg packaging container formed of a sheet-like material, wherein almost the entire upper wall of the lid is made substantially flat, and the inside of the lid is formed. A step is formed between the formed pillar and either one of the lid side walls in the longitudinal direction to separate the stored eggs from each other, and the product display label is almost entirely over the lid upper wall and the step is formed. Fine formed on almost the entire surface of the formed lid side wall
On the uneven portion, the upper wall 26 and the side wall 24
Since it is a structure that is attached to two sides , it is possible to minimize the possibility that the eggs collide with each other and damage them after packaging .
Can be easily removed from the micro-textured surface of the label.
There is a point.

[0014] Further, since the product display label is attached so as to cover the portion where the step is formed, the strength of the step forming side of the container when the lid is closed is sufficiently maintained, and the container may be distorted. This has the effect that the eggs are not damaged. Furthermore, the egg packaging container of the present invention requires only special changes in the structure of a part of the egg packaging container as compared with the conventional container, so that no special expense is required for manufacturing, and the manufacturing price does not increase. Therefore, in combination with the above-described effects, it is possible to expect the effect of improving the reliability of the product for both the producer and the consumer.
