Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is mainly used as a packaging container for distribution of chicken eggs, etc., and is provided with closures at a plurality of opposing locations on the body and the lid. A container in which a concave portion and a partition wall each having a small protrusion formed on the circumferential wall thereof are formed to form a space for storing eggs in the posture, and the body side and the lid side are one side. This relates to a container for eggs, etc., which is formed in a series and integrally in a foldable manner at the sides.

<Prior art> Conventionally, this type of egg container uses a series of synthetic resin sheet materials and molds the body part side and the lid part side into one piece by vacuum forming means or blow molding means. All of them were single-piece containers.

To store eggs in such an egg container, put the lower half of the egg into the recess on the body side, fold the lid side from the connecting part and put it over it, and then connect the free end flange pieces of these two parts. is polymerized, and the polymerized flange pieces are stapled or welded to close the entire container. Therefore,
There were no unexpected openings during the distribution stage.

<Problems to be Solved by the Invention> However, eggs are inherently extremely sensitive to impacts and break easily, and even when stored in the containers as described above, they often break during the distribution stage. For example, if one of the 10 eggs in a 10-egg container breaks, the other 9 eggs in the container will break.
The current situation is that individual eggs no longer have any value as a product and cannot be sold as they are. In order to sell these eggs as a product, it would be a hassle to open the container, wipe the dirty eggs, and refill them with other normal eggs into a new container.

In addition to such damage during the distribution stage, damage often occurs even after purchase by end users, often resulting in complaints to retailers.

This is the current state of affairs even when eggs are sold through normal distribution channels, so mail order methods, which are considered to be a different method of selling eggs, are at least able to sell eggs in a single piece than the conventional method of selling eggs. It is impossible to use egg containers because the risk is too great, and currently there is no mail-order sale of eggs.

Therefore, the present applicant aims to solve these problems, and hereby proposes an egg container with excellent impact resistance that has been able to solve these problems. In addition, it can be used as an egg container without any problems with the conventional means of opening using cables, and furthermore, it can be used as an egg container without any problems with the conventional method of closing the lid by stapling or welding. without causing any hindrance, and
The object of the present invention is to provide an impact-resistant egg container in which conventional closing means (closing machine) can be used without the need for modification.

Further, on the inner surface side (top side in the figure) of the continuous part 6, a cutting cable 7 made of thread, monofilament, narrow tape, etc. is arranged along the longitudinal direction of the continuous part 6. and its both end portions are fixed to the continuous portion 6. Further, cuts 8, 8 are formed on both longitudinal ends of the continuous portion 6 on both sides of the cutting cable 7, and a free end portion formed by the cuts 8, 8. serves as a knob 9 when the cutting rope 7 is opened.

Each of the recesses 1a and 1b has a large number of hemispherical small protrusions 3 sealed with air or other gas from the peripheral wall forming the recesses 1a and 1b toward the inner surface.
a..., 3b... are formed in a protruding manner.

In addition to the container body 1 shown in the upper half of FIG. 1, as shown in the lower half of FIG. The container-like body 11 has a body D and a connecting part 61 that connects the bodies C and D on one side, and the body part A and the lid part B are placed at 10 locations where the bodies C and D face each other. Inside a large number of small protrusions 3a, 3b, which have a shape slightly larger than the outer shape of the recesses 1a, 1b formed in the above, and which are formed by adhering the outer surfaces of the peripheral walls of these recesses 1a, 1b, and protrude independently toward the inner surface. It is formed by sealing a gas such as air inside. In this embodiment, each of the recessed portions 1c of the body side container-like body C is formed in approximately the same shape as the recessed portion 1a formed in the body portion A,
Although the shape is such that a partition 2c is formed between each recess 1c, 1c, the recess 1 of the lid-side container-like body D
No partition wall is formed between the recessed parts 1d, 1d, and the recessed parts communicate in the longitudinal direction and the width direction, and a conical pillar 10d is provided in the central part surrounded by the four recessed parts. The conical support 10d and the peripheral wall 1d' are formed to hold the lid B with a gap 5 between them and each recess 1b of the lid B. Reference numerals 8 and 8 in FIG. 1 are notches formed on both sides of both ends of the continuous portion 61, and the portion sandwiched between these notches 8 and 8 is formed as a grip portion 9 when opening the package.

Thus, the container-like body 11 formed in this way
Next, the container body 1 is polymerized as shown in FIG. In this way, the recesses 1a, 1 of the body A
The outer surface of the peripheral wall of b is the recessed part 1c of the body-side container-like body C,
Small protrusions 3a and 3b that are brought into close contact with the inner surface of body part A and lid part B to seal air such as air formed in body part A and lid part B.
protrude toward the inner side.

As shown in Fig. 4, the egg container constructed in this way accommodates eggs E in each recess 1a of body A, and covers lid B on top of body A. , Figure 1,
In FIG. 4, the flange portions 4d and 4c on the free end side of these bodies 1 and 11 or the triangular shape connected to the free end edge portion can be formed using a commonly used stapler or spot heat-sealing machine. The sealing machine uses staples, spot welds, etc. to close the package.

On the other hand, in this closed position, as shown in FIG. It is pasted to close the 10d forming part.

The egg storage packaging container formed in this way is
distributed in the market.

To open the package, as shown in FIG. 1, grip the knobs 9 formed at the ends of the continuous parts 6 and 61 and pull them outward to release the cutting cable 7. Due to the presence, the connected portions 6, 61 are cut.

In the embodiment shown in FIG.
The small protrusions 3a, 3b formed in the recesses 1a, 1b are replaced with the hemispherical ones shown in the first embodiment.
Small striped projections 3a, 3b along the depth direction of 1b
This shows an example in which the small protrusions 3a and 3b are formed to protrude toward the inner surfaces of the recesses 1a and 1b.

Forming the small protrusions in the form of convex stripes in this manner facilitates the die-cutting operation during manufacturing, and is convenient because the molding can be beautifully finished.

This small protrusion 3 is formed on the inner surface of the container body 1 to maintain the gap 5 formed between the two bodies 1 and 11, and if the sealed gas such as air acts as a buffer. good. Also, this means that
As in the embodiment shown in FIG.
It is sufficient that the structure is such that the egg does not receive direct external impact due to the buffering effect of gas such as air sealed inside the small protrusions 3a and 3b formed in the sixth part. In the case of the embodiment shown, the recess 1
Small protrusions 3a, 3b protruding from the inner surfaces of a, 1b
When looking at the projections of these small protrusions 3a and 3b, it can be seen that the remaining peripheral wall portion is in close contact with the inner peripheral surface of the recesses 1c and 1b, so these eggs and the container-like body 11 between the small protrusions 3a,
3b has a buffering effect due to the gas such as air substantially sealed therein.

Accordingly, in the present invention, it is preferable to form small protrusions 3a and 3b in these recesses to maintain the gap 5 between the egg and the container-like body 11.

In short, it suffices to have a structure in which the body side and the lid side are connected in the overlapping posture of both bodies 1 and 11. In addition, as the material for forming these bodies 1 and 11, a transparent synthetic resin sheet material is used.
This is preferable because the condition of the eggs can be checked from the outside,
For the opaque sheet or container-like body 11, a foamed sheet material or the like may be used.

The present invention can be implemented in this manner.

Although the embodiments considered to be representative of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments. It can be implemented with appropriate modifications within the scope of achieving the effects described below.

<Effects of the Invention> As is already clear from the above description, the present invention can be applied to other container-like bodies by keeping the outer surface of the container body in which a recessed portion for accommodating eggs is formed in close contact with the inner circumferential surface of each recessed portion. Since the structure protects the eggs from external impacts, the eggs can be sufficiently protected against external impacts by the buffering effect of gas such as air sealed in the independently formed protrusions, and the eggs can be easily removed. This prevents the containers from being damaged, making it possible to use them as containers for mail-order sales of eggs, which was unthinkable with conventional containers. Moreover, it does not cause any trouble to the automatic attachment means such as container opening cables or closing devices such as staples that have been used in the past, and does not require modification. It also has the effect of being usable.
