Description

[Detailed description of the invention] <Industrial field of application> This invention is mainly used as a packaging container for distribution of chicken eggs and quail eggs, and is made of synthetic resin sheet material by means such as vacuum or pressure molding. The present invention relates to an egg container using a film-like resin sheet material in which one side of a body part and a lid part are integrally connected via a connecting part so as to be freely openable and closable.

<Prior art> This type of container, when storing items such as eggs, polymerizes the free edges of the body portion and lid portion and secures the polymerized pieces with staples, welding, etc. It is used by closing the entire container.

It is well known that this type of egg container has individual egg storage recesses arranged and formed in approximately the same shape in the body and the lid. An egg container in which most of the container is formed as a flat surface without forming a recess for storing eggs has also been developed and is already known in the literature. Jitsukai Showa 60-62476
(Refer to the Japanese Patent Application Publication No. 2003-111013) When such egg containers store eggs and are displayed and sold at stores, etc., conventionally, they have been stacked only in a flat position. In addition, consumers who purchased this product usually put it in a flat position when putting it in a shopping bag or the like, and even when they brought it home, they only handled it in a flat position. This is due to the fact that the egg container itself was structured so that it could not be handled in any other position.

<Problem that the invention aims to solve> However, due to the need to display a wide variety of products in retail stores, etc., the display space for one type of product is limited; In order to prevent out-of-stock phenomena, products must be frequently replenished, and this replenishment is time-consuming and requires manpower. On the other hand, since the space of display shelves etc. is not necessarily an integral multiple of the planar orientation of the egg container, it may be necessary to display the product in an empty state.

On the other hand, when boiled eggs are packaged and sold together with seasonings, as seen in hot spring boiled eggs, it is known that the packaging container can be placed upright. In this known upright structure, in order to allow the packaging container to stand upright, a bulging portion that bulges outward is provided in the egg storage recess located on the side of the connecting portion that connects the lid and the body. It has a structure that forms. The bulging portion improves the stability of sitting when standing upright. (Refer to Japanese Utility Model Publication No. 60-40412.) However, with this known container with a bulging portion, it is impossible to stack containers vertically in multiple stages, and only one stage can be arranged on a flat surface.

Therefore, the inventor of this invention focused on these points, and even in such a limited exhibition space, it can be effectively utilized and stacked in a standing position or sideways standing position in every corner, and can be refilled in one go. It is possible to display as much as possible and reduce the number of times of replenishment, and the purchaser can also insert it into a shopping bag, etc., in a standing position or horizontally standing position, and it can also be used at home, etc. Here, we propose an egg container that has a structure that allows it to be handled in a horizontal or vertical position when taken home, or in an upright position if necessary. In addition, even if the egg container has a means for opening using a cord, this can be carried out without any problem, and furthermore, there is no problem with the means of closing the lid by stapling or welding, which are commonly used in the past. It is possible to use the conventional sealing means without causing any problems or the need for modification, and the size of the material used is also the same as the conventional one. It provides a good egg container.

<Means for solving the problems> The present invention is capable of achieving these objectives, and its configuration will be explained based on FIGS. 1 to 3 corresponding to the embodiments. It consists of a body part A and a lid part B that can be opened and closed, and a connecting part C that connects both parts A and B together on one side. In an egg container in which a plurality of recesses 1 for forming spaces, partition walls 2 for partitioning between them, and supports 3 are formed, the connecting portion C of the recesses 1 is provided.
At least two or more recesses 1 located on the same outer peripheral edge F, F', C side including The outer peripheral edges F, F' are formed with bulging portions 4, 4 formed on the direction side and substantially orthogonal to the outer peripheral edges F, F', C of the container, and on which the bulging portions 4 are formed. , C, the outer circumferential surface 41 is located on the outer circumferential edge F, C, F' side of at least two or more recesses 1... located on the outer circumferential edge F, C, F' side opposite to the outer circumferential edge 41 This is an egg container in which a bulge 4' is formed on the entry direction side and has a shape substantially perpendicular to the outer peripheral edges F, C, F' of the container.

<Operation> Since the present invention is constructed as described above,
As shown in FIG. 4 or FIG. 8, when the body part A and the lid part B are in the closed position,
In addition to being able to be displayed and used in a horizontal standing position or a vertical standing position, it is also possible to stack them one above the other in two or more tiers. In addition, when stacking two or more tiers, the bulging part 4 of the upper tier is placed on the bulging part 4' of the container of the lower tier.

<Example> Representative examples of the present invention will be described below based on the drawings.

The first embodiment diagrams shown in FIGS. 1 to 3 are for a container containing 10 eggs.
The figure is a perspective view of the body A and the lid B of the egg container in a closed position.
As shown in the front view of the structure, it has a normal body part A and a lid part B which can be opened and closed, and a connecting part C which connects both parts A and B on one side. There are 10 recesses to form egg holding spaces.
. . . partition walls 2 . . . and pillars 3 . . . that partition these recesses 1 . Of these 10 recesses 1..., the two recesses 1, 1 located at both ends in the longitudinal direction and located on the side of the connecting part C have a groove facing the side of the connecting part C. A bulging part 4, 4 is formed in the central part, and the outer surfaces 41, 41 protrude to a position on the concave direction side of the recess 1 and contact the connecting part C, and have a shape perpendicular to the connecting part C. There is.

Also, similar bulges 4',
4' is formed with the flange F' portion remaining.

The lid part B does not have individual recesses corresponding to the recesses 1, but the rest of the part except for the central part along the longitudinal direction is a series of recesses in the open position, and the bottom part 11a is made into a flat surface. It was formed. In addition, the lid part B is located at both longitudinal ends of the planar bottom part 11a (left and right ends in FIGS. 2 and 3), and extends in the width direction of the lid part B (vertical direction in FIG. 2). A T-shaped bulge 16 having a width approximately equal to the width along the side and a middle portion 15 protruding toward the center of the container, that is, a T-shaped bulge 16 with a short center leg, is attached to the lid. It has an anti-slip bulge 16 formed to protrude outward in the thickness direction of B (downward in FIG. 3), that is, toward the top surface of the lid B in the closed position. The center portion along the longitudinal direction of the lid portion B has a protruding surface portion 17 that comes into contact with the pillars 3 of the body portion A, and a small arc-shaped recess is provided on the side surface thereof at a position corresponding to the recess 1. An elongated protrusion having 18... is formed to prevent relative collisions of the contents. Further, step portions 19, 19 for forming air vent holes are formed in the longitudinal flange portions F, F of the body portion A and the lid portion B.

Further, on the inner surface side of the continuous portion C, the continuous portion C
A cutting cable D made of thread, monofilament, narrow tape, etc. is arranged along the longitudinal direction of the cable, and both ends thereof are fixed to the continuous part C. Also,
Notches 20, 20 are formed on both longitudinal ends of the continuous portion C, with the cutting rope D interposed therebetween, and the free end portion formed by the notches 20, 20 is It serves as a knob 21 when the cutting cord D is opened.

Therefore, the egg container made in this way has body part A.
The eggs are housed in each of the recesses 1, the lid is covered over the body A as shown in Fig. 1, and the free end flange portions F' of both parts A and B are stapled using the commonly used conventional method. Closures such as stapling or spot welding are performed using a closing machine such as a construction machine or a spot heat welding machine.

In this closed position, necessary information is printed on the surface of the planar bottom portion 11a of the lid portion B, or a printed sheet such as paper or resin film is attached as appropriate for use. Of course, it goes without saying that this printing and pasting of printed paper etc. may be performed before the eggs are housed.

Containers containing eggs thus formed are distributed on the market.

The containers containing eggs distributed in the market are shown in Figure 4 (Figure 7).
In the case of the embodiment shown in the figure, as shown in FIG. They will also be displayed stacked one after another.

To open the package, pinch the knob 21 formed at the end of the connecting part C shown in FIG. 1 and pull it outward. The installation part C is cut.

The embodiments shown in FIGS. 5 and 6 each have body part A.
This figure shows a rear view of the bulge 4, in which the number of bulges 4 is similarly formed in the concave portion located in the middle of the bulges 4, 4 shown in the first embodiment (Fig. 5). ,
This figure shows an example structure in which all the recesses are formed (FIG. 6).

In the second embodiment shown in FIG. 7, bulges 4 similar to the bulges 4 shown in the first embodiment are arranged at two ends of the container, respectively, located at both longitudinal ends of the container. In the recess 1..., the outer peripheral edge F, F in the longitudinal direction
It has a bulging structure that protrudes toward the side. The outer surfaces 41 of these bulges 4...
In this embodiment, the structure is shown in which the outer peripheral edges F, F are shaped to protrude to the outer ends.
As in the case of the embodiment shown in FIG.
Like the bulge 4' formed in the recess on the side of the free end flange F' shown in Figs. It is also possible to have a structure in which the outer circumferential edges F, F in the longitudinal direction are substantially absent by cutting at a position along the line. In this way, when the bulging portions 4 are formed in the longitudinal direction, the container can be used in an upright position in a vertically elongated position as shown in FIG.

The third embodiment shown in FIGS. 9 and 10 is a type of egg container in which an individual recess for protecting eggs is formed not only in the body A but also in the lid B at a position symmetrical to the body A. This figure shows an example structure in which the present invention is applied to an egg container. That is, body part A has the first
Similar to the body A in the embodiment, ten recesses 1 for accommodating the lower half of the egg, partition walls 2, and struts 3 are formed, and the recesses 1 on the side of the continuous part C at both longitudinal ends,
1 has a structure in which a bulging part 4 that protrudes toward the continuous part C side is formed, and the lid part B has a concave part 1 of the body part A and a bulging part 4 extending from the continuous part C toward the continuous part C. 10 recesses 1 to accommodate the upper half of the egg in symmetrical positions with the line
1... are formed, and partition walls 21... and pillars 31...
The recesses 1 are located on the side of the continuous part C at both ends in the longitudinal direction, similar to the body part A.
1 and 11, a bulging portion 4 protruding toward the connecting portion C side and reaching the connecting portion C is formed in a line-symmetrical manner with the connecting portion C as the center line, and as shown in FIGS. As shown in FIG.
is arranged to form a substantially straight line posture. In this case, the bulging portions 4 of both parts A and B,
4 is not limited to only two recesses, but may be implemented in three recesses or five recesses, as in the case of the embodiment illustrated in FIGS. 5 and 6. Needless to say. Further, the direction of protrusion is not limited to only the side of the continuous part, but may be formed so as to protrude 4' toward the free end outer periphery flange F' side, or in the longitudinal direction of the container as shown in FIG. It may be formed so as to protrude from the outer peripheral flange F side.

Therefore, the outer surface 41 of the bulged portion 4 referred to in the present invention does not need to protrude to the outer end surface of the continuous portion C or the outer peripheral flange F, but may be located at a position slightly deeper than the outer end surface. Alternatively, as shown in FIG. It may also be a cut piece.

Further, the bulge depth of the bulge portion 4 is formed to be approximately the same depth as the recess depth of the recess portions 1 and 11 as shown in the figure, which provides good stability when the bulge portion is in an upright position. According to the experimental results, it has been confirmed that the depth should be about half of the depth of the concave portions 1 and 11, so the depth of the concave portions should be approximately half of the depth of the concave portions.
It can be optionally implemented as having a depth of 100 mL or more.

In addition, the egg container according to the present invention has an egg storage recess of 5.
Although the container is shown as having 2 rows of 10 recesses, it goes without saying that it can also be implemented as a container having 2 rows of 6 recesses, 3 rows of 15 recesses, 4 rows of 20 recesses, etc., for example.

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> According to the invention, since the bulges are formed on the opposing outer peripheral sides, the egg container can be placed in a horizontal or vertical standing position, and the egg container can be held in either position. Since they can be stacked vertically in two or more levels, there are fewer restrictions on volume and space when displaying them.

Moreover, the egg container according to the present invention does not cause any trouble to automatic attachment means such as a container opening cord or closure device such as a stapler, and does not require extra sheet material. This also has the advantage of being able to be manufactured without any process.
