PROBLEM TO BE SOLVED: To solve problems in which eggs are easily broken and the packaging cost is increased for preventing damages to egg shells and also the distribution cost is increased because of the necessity of providing large cushioning spaces to protect the egg shells, and the storage properties of the fresh eggs are difficult to deal with unless they are refrigerated and the stock control is difficult. SOLUTION: The egg shells to be easily broken are removed from the eggs, and only contents of the eggs or cooking materials required for the contents are added to and stored in the packaging container 1. As a material for the packaging container 1, a resin, a glass and the like are preferred, and for instance, yellows 4 and whites 5 of the eggs are preferably stored in recesses 3A as storage spaces sealed and closed by sealing upper and lower packs 2 and 3 and the respective interiors of the recesses 3A are preferably vacuumized.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an egg in a packaging container containing eggs such as chicken eggs and quails. In particular, the present invention
The present invention provides a new method of transporting, displaying, and storing eggs in a packaging container by simplifying the structure of the packaging container itself by housing only the contents of the eggs excluding the shell.

[0002]

2. Description of the Related Art As one of the prior arts, Japanese Utility Model Laid-Open No.
7679. In this conventional structure, eggs and the like are shelled in a thin resin pack (normal egg state)
Normally, the eggs were arranged vertically with the vertical direction of the eggs, and lightly sandwiched between the upper and lower packs. The main purpose of this structure was to prevent the eggs from breaking due to the vibrations and shocks they receive during transport.

However, as is well known, this structure is not so strong in impact resistance. For example, when the truck is transported in the packaged state, the pack may be loaded too high, or the pack may be placed in an area of about 20 to 30 cm. When dropped on the floor from a height, there was an accident that the eggs inside were broken.

[0004] For this reason, for example, when transporting by truck, it is necessary for consumers to be careful to use another strong cardboard box or a resin container together or to prevent the container from being broken. It had been.

[0005]

SUMMARY OF THE INVENTION In view of these circumstances, the present invention improves the vibration resistance and shock resistance of eggs such as chicken eggs and quails, and does not require a large space for packaging. An object of the present invention is to provide an egg in a packaging container that can reduce the cost of the packaging container itself.

Another object of the present invention is to provide an egg in a packaging container that can minimize the amount of packaging material to be discarded at the distribution stage and at the consumer stage from the viewpoint of resource saving.

Another object of the present invention is to provide an egg in a packaging container which can be used for various kinds of cooking such as boiled eggs easily and hygienically for consumers and which is excellent in preservability.

[0008]

An egg in a packaging container according to one aspect of the present invention is characterized in that the contents of the egg from which the shell has been removed are housed in the packaging container in a sealed state that is shielded from the outside air. I do.

According to one aspect of the present invention, it is necessary to employ an impact-resistant structure in a packaging container for preventing the shell from being damaged by external pressure as in the case where eggs are stored in a shell state as in the prior art. Thus, an egg in a packaging container which is smaller, lighter, cheaper and less damaged than before can be provided.

[0010] Also, compared with the conventional pack structure, it is possible to reduce the loading space resulting from the impact-resistant structure,
For this reason, it is possible to contribute to reduction of manufacturing cost, resource saving, and reduction of distribution and transportation costs due to reduction of materials.

In one embodiment of the present invention, since the content of the eggs to be stored does not have a shape-retaining property, for example, a structure may be used in which the content follows and deforms when an external pressure is applied via a packaging container. The strength required for the packaging container itself can be considerably reduced as compared with the conventional structure.

[0012] Compared to the conventional method of discarding egg shells at homes, reliable batch processing at the manufacturing stage is possible and waste is reduced, and the shells are made of organic substances such as calcium extraction, organic fertilizer and other various kinds. Since it can be used effectively in relation to industry, agriculture, and biotechnology, it is also effective in resource saving, energy saving, environmental conservation, and the like.

[0013] An egg in a packaging container according to another embodiment of the present invention is a sealed egg in which the yolk and white, or only one of them, which are mixed by stirring the inside of the egg whose shell has been removed are shielded from the outside air. It is characterized by being housed in a packaging container in a state.

An egg in a packaging container according to still another embodiment of the present invention is obtained by mixing a cooking material such as a seasoning, a vegetable, or meat into the above-described egg in the above-mentioned various forms, and keeping the sealed state from the outside air. It is characterized by being housed in a packaging container.

As described above, depending on the contents of the egg cooking, the eggs are sold in a housed state in which white and yolk are mixed, in a housed state in which white and yolk are separated, or in a housed state in which cooking ingredients are mixed in the contents of eggs. This expands the appeal of the product, which was not possible with the shelled egg sales form.

Among them, the eggs separated into white and yolk are:
It can be used for food and cooking for people whose intake components are regulated without waste, and brings effects such as resource saving and energy saving.

The packaging containers used in these various forms are formed by polymerizing the first and second pack members, and the contents of the eggs are placed in the recesses formed in at least one of the first and second pack members. Can be accommodated. Even if the packing member is flexible, the commercial value of the contents of the egg is hardly reduced when an external pressure acts as described above.

Further, the packaging container may have a plurality of recesses, and a cutting means such as a perforation may be formed between two adjacent recesses.

[0019] In this way, by separating the cutting means at the boundary, the consumer can purchase only the required number of eggs, and can store the eggs without removing them from the pack as in the conventional case. Nothing to do.

The interior of the recess formed in the packaging container is preferably evacuated. In this case, the eggs are not contaminated by bacteria in the air in the storage space, and the storage period can be extended.

Further, the preservability can be improved by evacuating the inside and the like.
In addition to being used as an emergency food, inventory adjustment and inventory management can be made easier at consumers, producers, and retailers, and the risk of disposal due to expiration is reduced.

It is possible to have a third pack member which is further superimposed on at least one of the first and second pack members having a concave portion. At this time, a gap is formed between the third pack member and the recess, and the gap is preferably evacuated.

In this case, the void functions as a vacuum heat insulating layer, and can be suitably used as a structure for cooking eggs while reducing the temperature rise of the contents of the eggs, for example, for cooking hot spring eggs.

When the eggs are heat-treated together with the packaging container, the packaging container is preferably made of a heat-resistant material.

It is preferable that part or all of the packaging container is made of a material that allows the contents of the stored eggs to be seen through. This is because traders and consumers can determine the quality, type, and the like of the package contents from outside the packaging container.

An egg in a packaging container according to still another aspect of the present invention includes a shelled egg and a packaging container for accommodating the shelled egg, wherein the packaging container is composed of first and second packs which are superimposed on each other. A member, wherein the eggs with shells are accommodated in recesses formed in at least one of the first and second pack members, and at least one of the first and second pack members having the recesses Further, a third pack member to be superposed is further provided, and a gap having an air cushion function is formed between the third pack member and the concave portion.

When housing eggs with shells, breakage of eggs with shells can be prevented by using the space inside the third pack member as an air cushion layer.

[0028]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) FIG. 1 is a plan view showing an embodiment of the present invention, and FIG. 2 is a cross-sectional view cut in the longitudinal direction of FIG.

In FIGS. 1 and 2, the packaging container 1 is formed by polymerizing an upper pack 2 and a lower pack 3 as shown in FIG. In the example shown in FIG. 2, a recess 3A is formed only in the lower pack 3, and a yolk 4 and a white body 5 are formed in the recess 3A.
Are housed in a sealed state completely shielded from the outside air.

As shown in FIG. 2, the upper pack 2 made of resin, for example, is formed of a flat sheet member, and is polymerized, for example, on the lower pack 3 made of resin, so that the recess 3A formed in the lower pack 3 is formed. Acts as a closing lid. In this case, the molding of the upper pack 2 is simplified, so that the cost of the upper pack 2 can be reduced.

As shown in FIG. 1 and FIG.
A seal 1A is formed at a position surrounding A, and the yolk 4 and the white 5 are housed in the recess 3A in a sealed state completely shielded from the outside air by the seal 1A. The volume of the recess 3A is preferably slightly larger than the volumes of the yolk 4 and the white body 5 to be accommodated. Since the size of the eggs varies, the volume of the concave portion 3A is determined in consideration of the egg having the largest volume among the eggs to be stored. Of course, the packaging container 1 having the recesses 3A of a plurality of sizes may be properly used depending on the type of the egg.

In the present embodiment, a plurality of recesses 3A are provided at predetermined intervals in the longitudinal direction of the lower pack 2. A perforation 8 is formed between the two adjacent recesses 3A, 3A which functions as a cutting means for separating one recess 3A from the other during use.

Each of the areas separated by the two perforations 8 has a hole 10A penetrating through the upper pack 2 and the lower pack 3.
And a cut 10B. These holes 10
A and the cuts 10B are used for hanging the egg-containing packaging container 1, and only one of them may be formed.

When the consumer stores the packaging container 1 in each household, it can be stored in a refrigerator as it is at the time of purchase, or can be separated and stored in a space dedicated to eggs as before. At this time, they can be stacked as shown in FIG. 4 or wound and stored as shown in FIG.

In order to utilize the space of the refrigerator to the utmost, the holes 10 formed in the upper and lower packs 2 and 3 of the packaging container 1 are required.
A or notch 10B can be hooked or hung on a bar or a hook on a shelf in a refrigerator, thereby increasing the storage efficiency.

In order to manufacture the eggs in the packaging container, first, eggs whose shells have been removed, that is, yolks 4 and white bodies 5, are respectively accommodated in the plurality of recesses 3A of the lower pack, and the upper pack 2 is overlaid on the lower pack 3. , And FIG.
The sealing is performed along the sealing portion 1A indicated by a thick line.

At this time, if the housing operation, the polymerization operation and the sealing operation are performed in a vacuum atmosphere, the inside of the upper and lower packs 2 and 3 is evacuated, and the housing atmosphere of the yolk 4 and the white body 5 becomes anoxic. And growth of bacteria and the like can be suppressed. As a result, the eggs enclosed in the upper and lower packs 2 and 3 can be stored in the state of the pack 1 for a long time. Also, an appropriate sterilization treatment can be performed if necessary.

The above-mentioned sealing operation can be carried out by an adhesive applied on one of the surfaces of the upper and lower packs 2 and 3, or by the action of heat welding, pressure bonding, or the like.

Thereafter, perforations 8, holes 10A and cuts 10B are formed in the upper and lower packs 2 and 3 to complete the eggs in the packaging container. In addition, perforation 8, hole 10A
The cuts 10B may be formed in the upper pack 2 and the lower pack 3 in advance, and the upper pack 2 and the lower pack 3 may be aligned and polymerized.

In the egg in the packaging container thus constructed, since the insides of the upper and lower packs 2 and 3 are kept at a vacuum, the atmospheric pressure always acts. However, the yolk 4 and the white body 5 are filled in the recess 3A. Therefore, it has a shape-retaining property, and it is in a state where further deformation is hardly possible with a slight external pressure. Also,
Even if a large external pressure is applied, the container does not have a shape-retaining material such as a shell, so that the resin concave portion 3A and its contents can be deformed to absorb the impact, and the external pressure is removed. It will be restored to its original shape. Therefore, the commercial value is not lost due to the breakage of the shell as in the conventional case.

Particularly, in the present embodiment, a large number of eggs in a band-shaped packaging container shown in FIG. 1 are stacked as shown in FIG. 4 or wound around a core member 9 as shown in FIG. Can be displayed, stored. Even in this case, the egg shell is not broken and the commercial value is not lost unlike the conventional case.

As shown in FIG. 1, a packaging container provided with a plurality of recesses along one direction or a two-dimensional orthogonal
A packaging container provided with a plurality of concave portions along the direction,
When wound as shown in FIG. 5, the storage space can be reduced at the store, and the display method is unique as compared with the conventional display, and the appeal of the product is improved.

4 and FIG. 5, even when stacked or wound, the portions that come into contact with the packs are not square, so that the resin portions of the packaging containers 1 do not break and can be safely mounted. It can be transported hygienically and delivered to consumers.

In the conventional structure, when stacked as shown in FIG. 4, it is necessary to prevent the packs adjacent to each other at the top, bottom, left, and right from interfering with each other. , Was set to be much larger than the volume of the eggs with shells to be stored. As a result, the loading height,
The width had to be large, and the space efficiency at the distribution stage was poor.

In the configuration of the present embodiment, when the eggs in the band-shaped packaging container shown in FIG. 1 are loaded at the store shown in FIG. 4 or wound as shown in FIG. Can be purchased by cutting the required amount at the perforation 8.

As described above, even if a necessary number is purchased, each egg can be purchased while being stored in the packaging container 1, so that the eggs can be purchased without worrying about overlapping with other products in the shopping basket. .

If one of the upper and lower packs 2 and 3 is made of a transparent or translucent resin, for example,
You can check the color, size, etc. of the yolk, or check the difference in color, size, etc. depending on the place of origin or producer, and purchase it. It is one of the major features of the present embodiment that the quality of the image can be easily confirmed.

Either of the upper and lower packs 2, 3 or
If at least a part of the material is transparent or translucent, producers, factories, and retailers can also show the quality of the contents, differentiation from other companies, product differentiation, and appeal.

When using the eggs stored in the packaging container 1, the consumer first separates the eggs one by one at the perforations 8. When the contents of the egg are taken out, the parts of the upper and lower packs 2, 3 which are not adhered or welded are held with both hands, and peeled up and down against the joining force. After that, it is the same as the case of handling normal eggs, but it is excellent in cooking ability without breaking the shell.

When boiled before taking out the contents, that is, when making a boiled egg, boil using water and hot water in the same manner as boiling a normal egg with the upper and lower packs 2 and 3 adhered and welded. Good.

At this time, if the packaging container 1 is made of resin, the pack can be thermally expanded together with the contents at the temperature, so that the pack is not broken by heat.

If the upper and lower packs 2 and 3 are made of a heat-resistant resin having a heat resistance higher than 100 ° C., for example, a heat-resistant resin of about 150 ° C., the packaging container 1 can be directly put on a frying pan or a microwave oven. Boiled eggs, hot spring eggs and the like can be cooked in the packaging container 1.

(Second Embodiment) In the above-described embodiment of the present invention, one of the upper and lower packs 2, 3 has a flat shape as shown in FIG. 2, but the present invention is not limited to this. Not done. For example, as shown in FIG.
And the recesses 2A, 3A can be formed on both sides. By doing so, the form of the accommodation space formed by overlapping the recesses 2A and 3A can be configured to resemble the appearance of an egg, and the upper and lower packs 2 and 3 can be shared by the same parts. It has the effect of being able to work with the same mold.

Further, in the configuration shown in FIG.
4 are stacked in such a manner that the recesses and protrusions of the cross-sectional shape shown in FIG. 3 overlap with each other, so that the total height when the same number is stacked is lower than the loading height shown in FIG. be able to.

(Third Embodiment) FIG. 6 shows another packaging container provided with exterior packs 20, 21 further surrounding the upper and lower packs 2, 3 shown in FIG. This exterior pack 2
0 and 21 do not adhere to the concave portions 2A and 3A provided in the upper and lower packs 2 and 3, respectively, so that a gap 22 is formed.

The gap not only functions to buffer the eggs stored in the recesses 2 and 3 but also functions to alleviate a rise in the temperature of the eggs when the packaging container is cooked. The effect of reducing the temperature rise is useful when making hot spring eggs.

At this time, it is preferable that the space 22 is also evacuated. In this case, if the inside of the space 22 is evacuated, it can be used as a vacuum heat insulating layer in which not only the sterilization property of the space inside the space 22 is further secured but also the heat insulating effect in the space 22 is further enhanced.

In particular, when the contents of an egg are stored without a shell as in the present embodiment, the heat insulating effect of the shell cannot be expected. Can be. Thus, if the temperature of the inside of the egg is not excessively raised, the hot spring egg can be easily cooked.

However, even if air or another gas is present instead of a vacuum layer, the heat insulating effect is higher than that of a single-layer structure, and it is not always necessary to evacuate.

(Fourth Embodiment) Recently, health methods, treatment methods,
As a diet measure, dietary component adjustment has been adopted. For example, in eggs, yolk is good, but it is preferable to not eat white, or white is good,
Sometimes yolk should be avoided.

Conventionally, in such a method of use, an unnecessary portion is used for another dish, or is unavoidably discarded when it is unnecessary.

In this embodiment, attention is paid here, and a step of separating white and yolk is provided after removing the shell of the egg, and one of the white and yolk is sealed in a packaging container in this separated state. .

In this way, a product packed only with white meat and a product packed only with yolk can be manufactured and sold, and the consumer can make use of a plurality of types of products, including the above-mentioned non-separated product, the normal product, and the components described below, as necessary. It can be selected from among them, and there is no need to discard, which is preferable from the viewpoint of resource protection.

Another form of encapsulation is a form in which white and yolk are sold and mixed. Eggs need to keep their natural shape, white and yolk, because fried eggs, boiled eggs, etc. are often used in a mixed state with stirring.

In consideration of this case, the contents of these eggs should be agitated and mixed before being enclosed in the packaging container.
At the same time, it is conceivable to add necessary seasonings, vegetables, meat and the like.

When the above constitutions are appropriately combined, for example, the contents are mixed with fresh foods and fried eggs equivalent to natural products and mixed with seasonings, and further chopped with vegetables and meat in accordance with the usage conditions. A mixture of
A wide variety of products can be prepared such as those obtained by separating white and yolk. As described above, if the processing is performed so as to be easily handled according to each use situation, it is possible to respond to various needs of consumers.

As described above, an egg in which the contents, whites, and yolks are mixed by stirring, or in which a seasoning or the like is further added, does not necessarily have a natural shape of the contents. Then, after assembling the packaging container, for example, a liquid that has been agitated through a small injection tube may be injected into the interior of the packaging container.

In this case, as compared with a form in which the yolk is processed while maintaining its shape, for example, there are less handling precautions, it is easy to cope with automation, packing can be performed efficiently and efficiently, and low cost can be achieved. It can be keyed to make it.

In this case, since the hole for injection is small and possible, for example, the upper pack 2 of FIG. 2 is made of aluminum foil, and the upper and lower packs 2 and 3 are combined and joined, and then a part of the aluminum foil is formed. It is also possible to penetrate the injection tubule, inject the stirred egg, and then cover with a well-known seal or the like for sealing.

According to such a method, compared to the above-described method of enclosing and sealing the egg while keeping its natural state, it is possible to control the degree of vacuum and maintain a constant injection amount of the contents. Is easy, quality control is easy, and productivity is improved.

The eggshells produced during the production process in the practice of the present invention can be effectively used as organic matter in relation to extraction of calcium, organic fertilizer, and various other industries, agriculture, and biotechnology. Therefore, as compared with the conventional method of discarding egg shells at homes, reliable batch processing at the manufacturing stage is possible, waste is reduced, and resources and energy are saved, and environmental conservation is also effective.

(Fifth Embodiment) In the fifth embodiment, a packaged container having the structure shown in FIG. 6 contains eggs with shells. In this case, the storage space for the eggs formed by the concave portions 2A and 3A of the upper and lower packs 2 and 3 does not have to be evacuated. This is because the shell eggs are isolated from the fungus by the shells, and the shells themselves provide heat insulation when cooking hot spring eggs.

On the other hand, the gap 22 is not evacuated to exert an air cushion effect. The reason for forming the voids 22 in the fifth embodiment is that the action of the external pressure on the egg shell is buffered.

The present invention is not limited to the above-described various embodiments, and various modifications can be made within the scope of the present invention.

For example, in the packaging container shown in FIG. 2, the lower pack 3 may not be continuous as shown in FIG. 2, but each may independently form a cup. in this case,
The perforations 8 may be formed only on the upper pack 2. The cup-shaped container constituting the upper pack 2 may be made of glass or the like instead of resin.

In the structure shown in FIG. 3, one of the upper pack 2 and the lower cup 3 may be separated from each other without being continuous.

The upper and lower packs 2 and 3 do not need to be made of the same material, thickness and transparency. For example, the upper pack 2 can be made of the above-mentioned aluminum foil or the like, if necessary.

In the above-described manufacturing process, the upper and lower packs 2,
Although it has been described that the inside of the pack 3 is evacuated, this has an effect of keeping the inside of the pack in a sterilized state or a state in which bacterial growth is prevented.

However, in order to improve the storability, it is possible to use, for example, heat or light such as ultraviolet rays, or a gas such as ozone before or after sealing the upper and lower packs, in addition to the vacuum packs. is there.

If a gas permeable resin is used for the resin forming the packaging container, it is effective in sterilizing and sterilizing the inside of the pack.
Further, if the outside is coated with an antibacterial agent, this state can be maintained, and it can be carried into a sterile room of a hospital.

The perforations 8 can be formed by wedge-shaped notches.
