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 the body part is formed by vacuum or blow molding using synthetic resin sheet material. The present invention relates to an egg container using a film-like resin sheet material whose one side with a lid part is connected to each other via a continuous 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 in approximately the same shape in the body and lid, and also has recesses formed only on the body side and on the lid side. Egg containers that do not have individual egg-receiving recesses but are mostly flat surfaces have also been developed and are already known in the literature. (Showa 60-
(See Publication No. 62476) Conventionally, when such egg containers store eggs and are displayed and sold at stores, etc., they are simply stacked 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, in the known container with a bulge, the bulge is formed protruding from the center of the recess (that is, in a shape that extends outward in the radial direction of the recess). Therefore, the impact force acting from the outside is directly transmitted to the housed eggs via the bulge. For this reason, the conventionally known bulge cannot be said to be sufficient in terms of protecting the housed eggs from damage. I just couldn't line it up. 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 or the like in a standing position or horizontally standing position.
In addition, the structure has been designed so that it can be handled in a horizontal and standing position or, if necessary, in a standing position even when the eggs are taken home, and at the same time, the structure is such that external forces are not directly transmitted to the stored eggs to prevent damage to the stored eggs. Here, we propose an egg container that prevents this as much as possible.
In addition, this can be carried out without any problem even if the egg container has a means for opening using a cord, and furthermore, it can be used as a means of closing the lid by stapling or fusing, which is commonly used in the past. Conventional sealing means can be used without causing any hindrance or modification.
In addition, the present invention provides an egg container that can be made of materials of the same size as conventional ones.

<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 the recesses 1, and struts 3 are formed, the same outer wall including the connecting part C side of the recesses 1... The outer peripheral edge F of at least two or more recesses 1 located on the peripheral edge F, F', C side,
The outer surface 41 of the recess 1 is located on the side of the recess 1 facing the F', C side and excluding the central part 1a facing the outer peripheral edge F, F', C side of the recess 1. This egg container is formed in a shape in which a bulge 4 is formed in a row and is large and has a shape substantially orthogonal to the outer peripheral edges F, F', and C of the container.

<Operation> Since the present invention is constructed as described above,
As shown in FIGS. 3 and 4 or FIGS. 5 to 7, when the body part A and the lid part B are in the closed position, the bulge part 4 can be used to take the sideways standing position or the vertically long standing position. In addition, since the bulging portion 4 is installed in a portion of the recess 1 excluding the central portion 1a, external forces are not directly transmitted to the housed eggs. This prevents the stored eggs from being damaged.

<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 side of the egg container with body A and lid B in the closed position, and the structure is shown in Figure 2 as a plan view in the open state and in Figure 3 as a cross-sectional view. To,
It has a normal 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 on one side, and the lower half of the egg is held in 10 places in the body part A. Recesses 1 for forming spaces and these recesses 1
Partition walls 2... and pillars 3... are formed, respectively. Of these 10 recesses 1..., the two recesses 1, 1 located at both ends in the longitudinal direction and located on the continuous part C side have a portion facing the continuous part C side. The outer surfaces 41, 41 protrude from the left and right sides of the recessed portion 1a, excluding the central portion 1a, to a position in which the recessed portion 1 is in contact with the connecting portion C;
Swollen portions 4, 4 having a shape orthogonal to the continuous portion C are formed.

Further, similar bulges 4', 4' are formed in the recesses 1, 1 on the side of the free end outer peripheral edge flange F facing these bulges 4, 4, with the flange F portion remaining.

In addition, the egg container in this embodiment has individual recesses for protecting eggs not only in the body A but also in the lid B.
This is a type of egg container that is formed in a symmetrical position, that is, the lid part B also has a concave part 1 of the body part A and a line symmetrical position with the connecting part C as the center line. Ten recesses 11 for accommodating the halves are formed, and
It has a structure in which partition walls 21... and pillars 31... are formed, and the central portion 11a is located in the recesses 11, 11 located on the continuous portion C side at both ends in the longitudinal direction, similar to the body portion A.
The outer surfaces 41, 41 on both the left and right ends of the
A bulging portion 4 that protrudes toward the continuous portion C side to the continuous portion C formation position is formed in a line-symmetrical shape with the continuous portion C as the center line, and as shown in Figs. As shown, when the lid body B is in the closed position, these two parts A,
The outer surfaces 41, 41 of the bulging portions 4, 4 of B form a substantially straight line posture. Further, in the case of the lid part B, similar bulges 4', 4' are formed on the free end outer peripheral flange F side as in the case of the body part A.

Further, on the inner surface side of the continuous part C, as shown in FIG. 2, along the longitudinal direction of the continuous part C,
A cutting cable D made of thread, monofilament, narrow tape, etc. is provided, and both ends thereof are continuous parts C.
is fixed to. In addition, cuts 20, 20 are formed on both sides of the cutting cable D at both ends in the longitudinal direction of the continuous portion C.
The free end portion formed by 0 and 20 serves as a knob 21 when the cutting cable 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 body part A is covered with a lid part B as shown in FIG. Closures such as stapling or spot welding are performed using a closing machine such as a driving machine or a spot heat welding machine.

Containers containing eggs thus formed are distributed on the market.

The containers containing eggs distributed in the market are shown in Figure 4 (Figure 8).
In the case of the embodiment shown in the figure, as shown in Fig. 9), the continuous part C is placed downward and the outer surfaces 41, 41 of the bulging parts 4, 4 are used to stand it upright horizontally. They will also be displayed in stacks one after the other.

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 embodiment shown in FIG. 4 is a rear view of the body part A, and the bulges 4 are arranged in the middle part in the longitudinal direction in addition to the bulges 4, 4 shown in the first embodiment. A bulging portion 4 is similarly formed in the recessed portion 1 located therein.
This figure shows an example structure in which bulges 4 are formed in three first, third, and fifth recesses 1 along the longitudinal direction of the container. Further, the bulging portions 4 may be formed in all the recesses in the longitudinal direction of the container.

The second embodiment shown in FIG. 5 and FIG. The two recesses 1... have a structure in which they protrude toward the outer circumferential edges F and F in the longitudinal direction up to their end edges. In this embodiment, the outer surfaces 41 of these bulging portions 4 are shaped so as to protrude to the edge portions of the outer peripheral edges F, F as shown in FIG. 6. However, the outer surface 41 of the bulge does not necessarily need to protrude to the edge of the outer peripheral flange F, and as in the embodiment shown in FIG. 7, each of the bulges 4... The outer surface 41... is, for example, a concave proximal end portion of the concave portion 1, like the bulging portions 4', 4' formed in the concave portions 1, 1 on the side of the free end outer peripheral edge flange F shown in FIGS. 1 to 3. The flange portion is cut at a position along the outer surface 41, and the longitudinal outer peripheral edge F,
It may also have a structure in which F is substantially absent. As described above, when the bulging portions 4 are formed in the longitudinal direction, the container can be used in a vertically elongated upright position as shown in FIG.

Next, a third embodiment shown in FIGS. 8 and 9 will be described. The container of the third embodiment shown here is of a form mainly used for quail eggs, and the body part A is used for storing eggs as in the case of the embodiment of body part A shown in FIGS. 1 to 3 above. Ten recesses 1... are formed to accommodate the continuous portion C, and the two recesses 1, 1 located on the side of the continuous portion C at both ends in the longitudinal direction are provided with the continuous portion C as in the case of the first embodiment. The left and right side parts excluding the central part 1a facing the side are made to protrude and bulge, and the outer surface 4
As shown in FIG. 8, the bulging parts 4, 4 are formed so that they are substantially continuous with the continuous part C when the lid part B is in the closed position. In addition, the lid part B does not form individual recesses corresponding to the recesses 1...
The other portions except for the central portion along the longitudinal direction are formed into a series of recessed portions 11' in an open position, and the bottom portions thereof are formed into flat surfaces. In addition, the lid part B has a protruding surface part 15 in the center along the longitudinal direction that contacts the pillars 3 of the body part A, and has an arc-shaped side surface at a position corresponding to the recessed part 1. An elongated protrusion having small recesses 16 is formed to prevent the contents from colliding with each other. Further, step portions 17, 17 for forming air vent holes are formed in the longitudinal flange portions F, F of the body portion A and the lid portion B.

Therefore, in the case of the container, in the sealed position,
Required information is printed on the surface of the planar recessed part 11' of the lid part B, or a printed sheet such as paper or resin film is attached as appropriate. Of course, it goes without saying that this printing and pasting of printed paper etc. may be performed before the eggs are housed. In this case, the bulging part 4 formed in the body part A does not have to be formed only in the two recessed parts 1, 1, but in the fourth part.
It goes without saying that it may be formed in three recesses as in the embodiment illustrated in the figure, or it may be formed in five recesses. In addition, the protruding direction is not limited to only the continuous part side, but the protruding direction 4' is directed toward the free end outer periphery flange F side.
Alternatively, as illustrated in FIG. 5, it may be formed to protrude from the outer peripheral flange F side in the longitudinal direction of the container.

Further, the shape of the bulging portion 4 according to the present invention is not limited to the shape that bulges linearly on both sides of the recessed portion 1 except for the central portion 1a, as shown in the above embodiment figures. , as shown in FIG. 10, there is a shape in which the outer wall is an inclined wall at both sides of the recess 1 except for the central portion 1a, or a shape in which the wall on the central portion 1a side is an inclined wall (not shown). It can be implemented in any shape. Further, the bulging portion 4 does not need to be formed on both sides of the recess 1 except for the central portion 1a, and may be formed only on one side of the central portion 1a as shown in FIG. It is also good. In short, by making the central portion 1a non-bulging, the content of the egg, which is most susceptible to impact, is prevented from moving toward the outer periphery, and both sides or only one side of the egg is made to bulge outward. Any material may be used as long as it has a bulge that ensures the protection of the eggs and allows the container to stand upright.

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. The flange portion F may be cut.

Further, the bulging depth of the bulging portion 4 is formed to be approximately the same depth as the recess depth of the recesses 1 and 11 as shown in the figure, which provides good stability when in an upright position. Experimental results have confirmed that the depth should be about half of the depth of the recesses 1 and 11, so the depth of the recesses should be about half of the depth of the recesses.
It can be optionally implemented as having a depth of 100 mL or more.

Further, the bulging portion 4 may be formed to bulge arbitrarily on the lid B in the third embodiment shown in FIGS. As in the first embodiment shown in the figure, the formation positions of the body A side and the lid B side do not have to be line symmetrical; for example, the body A side is formed at 1, The lid B side bulges into the 3rd and 5th recesses, the body A side bulges into the 1st and 5th recesses, the lid B side bulges only into the 3rd recess, and so on. The portion 4 may be formed at different positions on the body side and the lid side. In short, it is sufficient that the container can be stably used in either a horizontal or vertical position with the side on which the bulging portion 4 is formed as the bottom surface.

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 per container, it can also be implemented as a container having, for example, 2 rows of 6 recesses, 3 rows of 15 recesses, 4 rows of 20 recesses, etc.

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 explanation, the present invention provides an egg container that has individual recesses for storing eggs, and because of the unevenness of the entire surface of the container due to the formation of these individual recesses, For egg containers, for which it was thought impossible to make them stand vertically, this concave part was used extremely effectively without destroying the original purpose of protecting the eggs.
A bulge is formed on the sides of two or more parts facing the same side except for the central part, and the outer surface of the bulge is formed so that it faces toward the recessed side of the recess and is substantially perpendicular to the flange surface. As a result, it has become possible to obtain an egg container that can be used in a horizontal or vertical position while also being able to reliably protect each individual egg.

Therefore, when storing and displaying eggs, when a purchaser purchases the eggs and stores them in a shopping bag, or when taking them home and placing them there, the eggs can be used horizontally or vertically as desired. It has the effect of being able to be handled conveniently in a situation that was previously unimaginable.

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. It also has the practical advantage of being able to be manufactured without any problems.
