Description

The present invention relates to a cutting device for cutting an eggshell shape, a reinforcing material for an eggshell shape, and an eggshell shape container from an eggshell shape, which is used to produce an eggshell shape container, for example, a container for cooking etc. It relates to a manufacturing method.

In the past, chicken eggs, which are typical examples of eggshells of this type, are relatively inexpensive, stable in price, and abundant in nutrition as price honors, and thus are used alone for food, as well as French cuisine and Japanese cuisine. It is extremely useful as a cooking material in a variety of culinary cultures, and is consumed in large quantities especially by restaurants such as cake shops and mayonnaise manufacturing plants. Then, most of the eggshells remaining after taking out the egg solution of the hen's egg are discarded as waste as they are, or are rarely used as a material for white line drawing or as fertilizer for vegetable gardens.

Also in school education, forming a sustainable society by "conserving the natural environment and the use of science and technology" and "practicing environmentally conscious consumer life" in the school guidelines is specified as a major education issue. Although most of the eggshells used in home economics etc. are discarded as they are, they have not been used as plant materials for science plant cultivation or as materials for egg art in the art department. Missed the opportunity to practice.

The eggshell is found to have the value of its natural design beauty, despite the fact that it is an essential material for business such as almost all Western-style cake shops and restaurants as well as the industrial site of mass broken eggs for taking out egg solution Without, it has been discarded naturally. The eggshell is found to have the value of its natural design beauty, despite the fact that it is an essential material for business such as almost all Western-style cake shops and restaurants as well as the industrial site of mass broken eggs for taking out egg solution Without, it has been discarded naturally.

However, using eggshells of chicken eggs as materials for containers means that society recognizes that they have been disposed of until now. In addition, since eggs are not self-sustaining, it has been necessary to procure “ogarettes” made of pottery or metal since the history of French cuisine etc.

Pieces cut from the eggshells of chicken eggs have not been used as lids and have been discarded as waste. Even in relation to eggshells, conventional food containers and designs based on the natural design beauty of eggs or glass containers used glass or plastic containers that are difficult to be reduced to the natural world.

And conventionally, various devices have been proposed for the purpose of efficiently removing egg yolk and egg white from the inside of eggshells of chicken eggs.

For example, in the egg shell opener disclosed in Patent Document 1, a laser beam is focused on a predetermined position of the egg shell and irradiated to cut the egg shell in a state in which the egg shell membrane is left, and the egg shell is the egg solution In addition, it is possible to prevent a characteristic period in which egg white generated at the time of cutting by a laser beam burns, while preventing mixing into the glass.

Further, in the eggshell cutting device disclosed in Patent Document 2, the holder is used to fix the egg at a predetermined position with the top of the head facing upward, and the cutter for controlling the blade position is lowered from above with the cylindrical blade facing the egg The cylindrical blade is pressed against the top of the egg and rotated to cut a part of the eggshell of the egg.

Furthermore, the chicken egg shell cutting device disclosed in Patent Document 3 is fixed by the chicken egg fixing tool with the blunt end of the chicken egg facing upward, moved up and down by the cutting machine fixing mechanism, and the cutting tip is chicken After fixing the ultrasonic cutting machine in a state of being in contact with the blunt end, ultrasonic vibration is transmitted from the ultrasonic vibrator of the ultrasonic cutting machine to the cutting tip to cut the blunt end of the chicken egg There is.

In the G7 Marine Plastics Charter, although the policy has become an international issue, as mentioned above, the utilization of eggshells of chicken eggs is conventionally limited, and eggshells can be discarded without being effectively used. There were many. Further, as containers for containing food and the like, there are many containers made of glass and plastic which are difficult to be reduced to the natural world, and there are almost no examples in which eggshells are used as containers and the like.

In order to use an eggshell as a container etc., the fragility of an eggshell becomes a problem. In particular, depending on how to cut off a part of eggshell, it becomes very fragile when burrs are generated at the cut opening edge. In addition, if the eggshell as a container is broken, not only the appearance but also the leakage of the contents and the quality deterioration of the contents due to the contact with the outside air occur. In addition, taking as an example the creation of a stable container from eggshells of raw eggs, it has natural pores even if it is cut cleanly, and it is necessary to coat and strengthen the unevenness of the cut cross section There is. Therefore, in order to repeatedly and effectively use eggshells as containers for various uses, it is required to enhance the strength and durability of the eggshells.

Furthermore, according to the eggshell opening device disclosed in Patent Document 1, since the laser beam is used, a device for generating the laser beam is required, and the device becomes large. Further, also in the eggshell cutting device disclosed in Patent Document 2, a holder for fixing the egg at a predetermined position with the top of the head facing upward and a blade position control for lowering the cylindrical blade toward the egg from above The device is large because it is configured to have a motor. Furthermore, in the chicken egg shell cutting device disclosed in Patent Document 3, a chicken egg fixing tool for fixing with the blunt end of the chicken egg facing upward, and vertical movement for bringing the cutting tip into contact with the blunt end of the chicken The device is large in size because of the possible cutter locking mechanism.

Furthermore, the reinforcing material according to the present invention is a reinforcing material for reinforcing an eggshell shaped material, which is laminated on at least a part of the eggshell shaped material and has a first layer mainly composed of an edible water-soluble substance And a second layer laminated on the first layer and containing an edible thermoplastic material as a main component.

In the reinforcing material configured in this manner, the first layer containing an edible water-soluble substance as a main component is laminated on at least a part of the eggshell shaped material and dried, and then it is possible to form the first layer on the first layer. By laminating and heating and curing the second layer containing an edible thermoplastic substance as a main component, for example, an eggshell-shaped object whose strength is extremely reduced if a part of the eggshell or the like is cut off While reinforcing it, when using an eggshell shaped thing as a container etc. of a food, it can prevent the human damage at the time of putting a mouth accidentally. At the same time, dissolution of the first layer when water adheres to the surface can be prevented by the second layer.

Further, in this configuration, since the water-soluble substance is pullulan, the adhesion and film formability of the first layer to the eggshell shaped article can be improved.

In this case, the first layer contains water and the pullulan, and the content of the pullulan is 12.5% by weight or more and 17.5% by weight or less with respect to the water. That is,
If the content of pullulan to water is higher than 17.5% by weight, the amount of pullulan adhesion to the eggshell shape becomes too large, and the first layer is likely to have a pool of the adhesion surface of the eggshell shape and the drying time is long. turn into. On the other hand, if the content ratio of pullulan to water is lower than 12.5% by weight, the adhesion of pullulan to the eggshell shape decreases, and the eggshell shape 1
Layer is likely to come off. Therefore, the content of pullulan to water is preferably 12.5% by weight or more and 17.5% by weight or less from the viewpoint of adhesion to an eggshell shape and drying time.

In this case, the first layer contains water and the pullulan, and the content of the pullulan is 15% by weight with respect to the water. That is, when the content ratio of pullulan to water is 15% by weight, it is particularly preferable because appropriate adhesion to an eggshell shaped product can be secured and drying can be performed in a relatively short time.

Also, in this case, since the thermoplastic substance is a shellac, it has the property of being soluble only in an alcohol-based solution, so that the dissolution of the first layer in the case where water adheres to the surface is appropriately determined. It can prevent.

Furthermore, the coating layer 16 may be a single layer of, for example, cellulose nanofibers, but may be composed of a plurality of layers, for example, two layers. Specifically, as the coating layer 16, a first layer 18 directly laminated on the outer surface 21a of the eggshell 21 and the cut end face 21c, and a second layer laminated on the first layer 18 It consists of nineteen. The first layer 18 is a layer mainly composed of pullulan, which is a water-soluble polysaccharide, contains water and pullulan, and the content of pullulan is 12.5% by weight to 17.5% by weight with respect to water Or less, more preferably 15% by weight
It is assumed.

Here, pullulan (pllulan) is a molecular formula C ₆ H ₁₀ O ₅ and is a colorless and transparent compound which is a kind of polysaccharide consisting only of glucose. And, pullulan has a structure in which maltotriose in which three glucose molecules are α1-4 bonded is connected by α1-6 bond. Further, pullulan is excellent in solubility, has a property of being rapidly dissolved in water, is excellent in viscosity, adhesion, adhesiveness, adhesiveness, film-forming property, film-forming property, etc. and is edible. Therefore, pullulan is a substance capable of forming an edible water-soluble molded product, a specific layered film, when it is heated and molded by adding a certain amount of water. Furthermore, pullulan has been confirmed to be safe in acute toxicity, subacute toxicity, chronic toxicity and mutagenicity, and is treated as an additive without limitation in use in Japan.
By using pullulan as the first layer 18, eggshells 20, 21 and 22 of the egg 20 are obtained.
The adhesion and film formability of the first layer 18 to the In addition to the pullulan, the first layer 18 can also use various components such as vegetable resin which is a water-soluble polysaccharide such as gum arabic as a main component.

The second layer 19 is a layer mainly composed of shellac which is a thermoplastic resin. Shellac (Laccifer lacc)
a) A resinous substance obtained by purifying an insect-body coating material secreted by several kinds of scale insects such as a). Shellac is a clear, tasteless and odorless substance harmless to the human body, and is a brightener preparation having a freshness maintaining effect generally used as a coating material for food. Shellac has the property of being soluble only in alcohol solvents such as ethanol, for example, and is a moisture-proof material capable of forming a transparent film by drying the alcohol solution of shellac and evaporating the alcohol.

Therefore, after applying an aqueous solution of pullulan to the eggshells 20, 21 and 22 of the egg 30, it is dried to form the first layer 18, and shellac liquid is applied on the first layer 18 to volatilize the alcohol and harden it. The eggshells 20, 21 where strength is extremely reduced when cutting off a portion by
Even if it is 22, although it can reinforce strongly, when the container 10 comprised by the eggshells 21 and 22 is used as a container etc. of a foodstuff, the human damage at the time of putting a mouth accidentally can be prevented.
At the same time, the second layer 19 can prevent the first layer 18 from melting when water adheres to the surface.

Moreover, the container 10 may be used as a pot etc. for plant cultivation. Therefore, by forming the coating layer 16 with a natural component, the container 10 is reduced to the soil by being buried in the soil. Therefore, the container 10 may be embedded in the soil together with the plant, and is also useful as a container for raising seedlings. At this time, by putting the eggshell 23 into the container 10 earlier than the culture soil for cultivation, the air can easily enter the culture soil in the container 10, and rooting of the plant to be cultivated can be improved.

Since the container 10 buried in the soil is reduced to the soil, it is not necessary to dig up and collect the container 10 as in a conventional synthetic resin pot, and to perform cleaning, storage, management and the like. Also, in acidic soil, the soil is neutralized by filling the container 10 consisting of eggshells 20 and
h value is high and soil can be improved. Moreover, the plant planted in the container 10 is wrapped by the container 10 except for the upper part where the sprout extends. Thereby, the container 10 exhibits the effect excellent in prevention and moisture retention of nutrient outflow. Further, when it is not desired to inhibit root growth, only the lower part of the container 10 may be divided and planted.

Moreover, as the container 10, it can also be used as a container for culture space for culture | cultivating an iPS cell, a muse cell, etc.

Furthermore, when the container 10 is used as food, a spoon is often attached. In this case, when using the container 10 after meals as a container for plant cultivation,
It can be used as a scoop for cultivating soil, that is, a shovel for cultivation. In addition, this bowl is provided with a part that can display the type of seeds, cultivation history, etc., or it is formed or coated with a material that makes it easy to draw letters, pictures, etc. It can be used. In addition, it is possible to add functionality to this soil to indicate the degree of moisture retention and dryness of the soil. Therefore, it is also possible to create a horticultural culture in which the cultivation situation and cultivation environment are visualized and enjoyed by the cultivation center in which an information terminal such as a smartphone and a dedicated application are linked.

Moreover, the container 10 can be used for pudding, and by attaching the canal type container containing a caramel source to this container 10, this canal type container can be used as a canning for cultivation. Then, by pinching the tip of the spout of this caning container or twisting it to remove the lid, the caramel sauce in the canned container is opened, and this canned container is crushed and used like a dropper. Can remove caramel sauce from the can-type container.

Next, FIG. 4A is a plan view of an egg 30 which is a material of the container 10. Figure 4 (B),
It is a front view of egg 30. The air chamber side of the egg 30 which is formed to be slightly thick is referred to as the upper side, and the opposite end side which is the slightly pointed end side is referred to as the lower side. Moreover, when forming the container 10, the dashed-dotted line shown to FIG. 4 (A) and FIG. 4 (B) has shown the location where the egg 30 is cut | disconnected. here,
The egg 30 is a brittle material having a property of being substantially free from plastic deformation and breaking when an external force is applied, since calcium carbonate is a main component and has many pores.

As shown in FIG. 4 (A) and FIG. 4 (B), the egg 30 is cut at the cutting portion 31 to form an eggshell 21 to be the main body portion 11. The cutting portion 31 is substantially perpendicular to the central axis of the egg 30, and is substantially circular in plan view. In addition, in order to improve the designability of the container 10, the cutting part 31 may be formed, for example, in a substantially wave shape. The distance L2 from the upper end of the egg 30 to the cutting portion 31 is preferably equal to or less than one third of the height L1 of the egg 30. That is, the height L 3 of the eggshell 21 to be the main body 11 is two thirds or more of the height L 1 of the egg 30. Thus, the eggshell 2
1 is a suitable size for the container 10.

Further, the egg 30 cut off by the cutting portion 31 becomes the pedestal main body 13, and the upper portion of the pedestal main body 13 is further cut by the cutting portion 32, whereby the eggshell 22 to be the pedestal portion 12 is formed.
That is, the pedestal main body 13 is a small-piece portion as a lid body configured by the eggshell 22 and the eggshell 23 cut at the cutting portion 32. The cutting portion 32 is above the cutting portion 31 in the egg 30 and has an outer diameter smaller than the external dimension of the cutting portion 31, and the cutting portion 31 and the cutting portion 32
And are almost parallel. Therefore, by forming the main body portion 11 and the pedestal portion 12 of the container 10 from the eggshell 20 of the egg 30, it is possible to effectively reuse the conventionally discarded eggshell 20 as the container 10. Thereby, the discarding amount of the eggshell 20 of the egg 30 can be reduced. In addition, since it is not necessary to separately purchase a container or pedestal made of glass or plastic as a container for food or the like, consumption and waste of glass or plastic can be reduced. Therefore, it is possible to provide sustainable awareness as well as great directing effects on French and Japanese cuisine, especially Western culture.

Further, the main body portion 11 and the pedestal portion 12 constituting one container 10 are separate eggs 30 respectively.
Can also be formed from eggshells 21, 22 obtained from That is, the eggshell 21 obtained by excising one eggshell 20 is combined with the eggshell 22 obtained by excising the other eggshell 20 to constitute the container 10. As a result, the production efficiency of the container 10 is enhanced, and the eggshell 21,
22 can be selected, and the design of the container 10 is enhanced. However, the eggshell 20 is cut 3
Even if it is opened at 2, it can be used as a container which is excellent in moisture retention and increased in strength compared to the container 10.

In addition, since the egg 30 is a natural thing, the size is different for each individual. Therefore, the height L3 of the main body 11 may be adjusted by appropriately changing the position of the cutting portion 31 according to the height L1 of the egg 30. In the above example, although the upper part of the egg 30 is cut off to form the main body part 11, the configuration of the main body part 11 is not limited to this, for example, the lower part of the egg 30 is cut off,
The eggshell 20 on the air chamber side of the egg 30 may be used as the main body 11. Further, for example, the main body portion 11 may be formed by cutting the egg 30 in the vertical direction, that is, in the central axis direction.

Furthermore, the coating layers 16, 1 formed on the outer surfaces 21a, 22a of the eggshells 21, 22.
7 is not limited to the above example, and may be formed on at least a part of the outer surfaces 21a and 22a of the eggshells 21 and 22. Specifically, the coating layers 16 and 17 are formed so as to cover portions with weak strength, for example, the end face 21c of the cut portion 31 of the eggshell 21 and the end faces 21c and 22c of the cut portions 31 and 32 of the eggshell 22. Also good.

In addition, the eggshells 21 and 22 may be used in the container 10 in a state where an eggshell membrane is left on the respective inner surfaces 21b and 22b. Thus, the eggshells 21 and 22 are protected by the eggshell membrane, and the container 1 is
The strength of 0 is enhanced and reinforced. In addition, the coating layer 1 on the inside of the eggshell membrane of the inner surface 21b
Six may be formed. Thus, the eggshell 21 is protected by the eggshell membrane and the coating layer 16 to enhance and reinforce the strength. Similarly to the eggshell 21, the coating layer 17 may be formed on the eggshell membrane for the eggshell 22 as well. Further, by adjusting the thickness of the coating layers 16 and 17, the outer surfaces 21a and 22 of the coating layers 16 and 17 can be obtained.
The sizes of the eggshells 21 and 22 covered with a may be equalized to absorb individual differences between the eggshells 21 and 22.

Moreover, eggshells 21 and 22 may be used for container 10 in the state where an eggshell membrane was removed. Specifically, the eggshell membranes of the eggshells 21 and 22 may be washed or the like and peeled off with ethanol, water or the like. As a result, there is no risk of rot of the eggshell membrane and the storage property of the container 10 is enhanced. Alternatively, the coating layers 16 and 17 may be formed on the inner surfaces 21b and 22b from which the eggshell membrane has been peeled off. That is, eggshells 21 and 22 which are not covered with a coating agent such as the coating layers 16 and 17 may be used.

From the above, in the container 10 according to the present invention, when one raw egg 30 is taken as an example, one egg 30 does not exist immediately in front of or in the refrigerator, but one egg yolk and one egg white only. In addition, a world view is created in which there is a material that creates the material of one main body 11 and the material of the pedestal 12 that makes the main body 11 stand on its own. Furthermore, implementing the present invention in the form of eggshells centered on raw eggs 30 is not only in terms of food culture and nourishment, but also ecologically towards a sustainable society, as well as Easter eggs and the like. Redesigning the world view as an icon of life, birth, revival, revitalization, property, etc. as an icon in the context of ethical consumption culture, innovation, and so on It is the true apex of a true Columbus egg, and it is an inclusive culture creation by universal design, brought about by the aesthetic beauty of nature that will never go away even after thousand years.

[Method of manufacturing container]
Next, with reference to FIG. 5, the manufacturing method of the container 10 which is an eggshell shaped container is demonstrated in detail. In the following description, FIGS. 1 to 4 will be referred to as appropriate.

FIG. 5 is a flowchart showing manufacturing steps of the container 10 according to the embodiment of the present invention. As shown in FIG. 5, in the manufacturing process of the container 10, a sterilization process S10 and a first coating process S2 are performed.

A second split egg process S60, a second cleaning process S70, a second coating process S80, and a printing process S90 are provided.

First, the disinfection step S10 is performed as necessary. In the disinfection step S10, the surface of the egg 30 is disinfected with food grade ethanol or the like. Thereafter, the egg 30 is left for a predetermined time to naturally dry the surface.

Next, a first coating step S20 is performed as necessary. First coating step S
At 20, the coating layers 16 and 17 are formed and reinforced on the entire surface of the eggshell 20 of the egg 30. At this time, by using a colored coating agent for the coating layers 16 and 17, it is possible to suppress the color unevenness of the eggshell 20 which is a natural product but which is specific, that is, the base unevenness.
In addition, by performing the first coating step S20, a first split egg step S3 described later will be described.
It becomes possible to stably perform the split egg at 0.

For example, when the coating layers 16 and 17 are formed by laminating the shellac-based second layer 19 on the surface of the pullulan-based first layer 18, the water and the pullulan can be used. The egg 30 is dipped in a mixture of pullulan aqueous solution, and the pullulan aqueous solution is applied to the surface of the egg 30. Next, the egg 30 coated with the aqueous solution of pullulan is heated by a heating device such as an oven, blown with hot air with a dryer, or naturally dried to dry, and the aqueous solution of pullulan is cured to harden the surface of the egg 30 Form a first layer 18.

Thereafter, the egg 30 formed by laminating the first layer 18 on the surface is immersed in shellac liquid (a solution in which an alcohol such as shellac and ethanol is mixed) to form the first layer 18 of the egg 30.
Apply shellac solution on top. Next, the egg 30 to which shellac liquid has been applied is heated by a heating device such as an oven, blown with hot air with a dryer, or naturally dried to evaporate the alcohol component in the shellac liquid, thereby Harden the first of the eggs 30
The second layer 19 is formed on the first layer 18 by laminating.

At this time, a coating agent such as pullulan aqueous solution or shellac liquid is applied to the eggshell 20 of the egg 30 using an ultrasonic mechanism or a microbubble generator (not shown) to sterilize the eggshell 20 and simultaneously this eggshell 20. Fill in the pores and burrs of the
0 may be made more robust.

When the coating agent used as the coating layers 16 and 17 is naturally dried, a drying jig 900 described later is used. The respective eggshells 21 insert the columns 902 of the drying jig 900 into the openings 14 of the respective eggshells 21 with the openings 14 directed downward, and are opposed to the openings 14 of the respective eggshells 21. The inner surface 21 b is placed to be placed on a buffer member 903 attached to the tip of the support 902. The pedestal main body 13 is installed so that the inner surface of the end of the pedestal main body 13 is placed on the buffer member 903 of the drying jig 900 with the cutting portion 31 side facing downward. .

Next, the first egg breaking step S30 is performed. In the first dividing egg step S30, the egg 30 is cut at the cutting portion 3
In 1, a cutting machine 100A etc. mentioned later cut | disconnects. The egg breaking machine 100A or the like has, for example, a substantially disk-like cutting blade main body 102A, and ultrasonically vibrates or rotates the cutting blade main body 102A to make the blade 112A of the cutting blade main body 102A an egg. By bringing the eggshell 20 into contact with a predetermined position of the eggshell 20, a part of the eggshell 20 of the egg 30 is partially cut off by the cutting portion 31 and cut into the eggshell 21 and the pedestal main body 13 to be the main body portion 11. . Then, the egg 30 is separated into the contents and the eggshells 21, 22, 23. The contents of the egg 30 are used, for example, as a material for a confection.

Here, after the coating layers 16 and 17 are formed on the surface of the egg 30 in the first coating step S20, the eggshell 20 of the egg 30 is protected by the coating layers 16 and 17 by performing the first splitting step S30. Since the reinforcement is reinforced, cracking and the like of the eggshell 20 at the time of the split egg in the split egg process S30 can be prevented. In addition, the eggshell 20 of the egg 30 is cut by the egg breaking machine 100A or the like, whereby cracking of the eggshell 20 of the egg 30 is reduced and the strength is increased as compared with the case where the eggshell 20 of the egg 30 is divided manually. . In addition, the container 10 is used by using the split egg machine 100A or the like.
Can increase the productivity of

Next, a first cleaning step S40 is performed as necessary. In the first cleaning step S40, the outer surface and the inner surface of the eggshell 21 and the pedestal main body 13 to be the main body 11 are rinsed by washing with water or the like, and the cutting pieces attached to the eggshell 21 and the pedestal main body 13 And egg yolk, egg white, eggshell membrane etc. gradually.

Thereafter, an edge coating step S50 is performed as necessary. In the edge coating step S50, the coating layers 16 and 17 are respectively formed on the edge portions of the eggshell 21 and the pedestal main body 13 by the same method as the first coating step S20. In the edge coating step S50, the eggshell 21 and the pedestal main body 13 are each dipped in a pullulan aqueous solution or shellac solution and coated, as well as the end face 21c of the eggshell 21,
Partially immerse the cutting part 31 side of the pedestal main body 13 in pullulan aqueous solution, shellac liquid, etc.
The end face 21c of the eggshell 21 and the end of the cut portion 31 of the pedestal main body 13 may be partially coated.

Next, a second split egg step S60 is performed. In the second split egg process S60, the pedestal main body 13 is cut by the cutting unit 32 by a split egg machine 100B or the like described later. Specifically, the cutting blade main body 102B of the egg breaking machine 100B is ultrasonically vibrated or rotated, and the cutting blade main body 102 is produced.
By bringing the blade 112B of B into contact with the central position on the end side of the pedestal main body 13, the end of the pedestal main body 13 is partially cut off and cut at the cutting portion 32, and separated into the eggshells 22, 23. Be done.

Next, a second cleaning step S70 is performed as necessary. In the second washing step S70, eggshell 2
2 and the outer surface 22a and the inner surface 22b are rinsed with water, etc.
Gradually attach the cutting pieces etc. attached to.

After this, a second coating step S80 is performed as necessary. In the second coating step S80, the coating layers 16 and 17 are formed on the outer surfaces 21a and 22a of the egg shells 21 and 22, respectively, by the method similar to the method described in the first coating step S20. The main body 11 and the pedestal 12 are formed. In the second coating step S80, the coating layers 16 and 17 may be formed on the inner surfaces 21b and 22b of the egg shells 21 and 22, respectively. In this case, the eggshells 21 and 22 are immersed in a pullulan aqueous solution or shellac solution to form the coating layers 16 and 17 on the entire surface.

As described above, by performing the first coating step S20 and the second coating step S80, the coating layers 16 and 17 are each formed into a plurality of layers in a thick manner. Therefore, the strength of the eggshells 21 and 22 can be increased.

Then, printing process S90 which applies an irreversible temperature indicator to the outer surface of the container 10, for example, the outer surface 21a of the eggshell 21 may be performed. In the printing step S90, a temperature indicator may be printed on the outer surface of the container 10 so that it can be checked how many hours, for example, steamed, that is, heat-treated, the container 10 is. Thereby, for example, in the case of using as a container 10 for food, by using an irreversible temperature indicator that reacts by heating at a predetermined temperature or more for a predetermined time,
As it can be used as a measure against sterilization of various microorganisms including salmonella bacteria,
The occurrence of food poisoning and the like can be appropriately prevented, that is, the cooking management can be easily performed, and the safety can be enhanced. At the same time, it is possible to facilitate heat retention management when used as a container 10 for food, for example.

Note that, instead of the printing step S90, the sealing material to which the temperature indicator has been applied in advance is a container 10
It may be stuck on a predetermined position of the outer surface 21a of the. Further, the thermophilic agent may be applied to any position of the container 10, for example, the thermochromic agent may be mixed with the coating agent used for the coating layers 16 and 17. In addition, it may be a thermochromic agent capable of determining whether the contents of the egg 30, that is, egg yolk or egg white is in a raw, semi-ripened or fully-ripened state. Furthermore, the reaction of the temperature indicator can bring out the display of serial numbers, serial barcodes, QR codes (registered trademark), barcodes, identifiers and the like that enable traceability. Also, for various displays such as serial numbers, serial barcodes, QR codes (registered trademark), barcodes, identifiers, etc. that enable such traceability, for example, an inkjet printer etc. You may use and print.

At this time, each of the containers 10 can be provided with a unique identification code. In this case, the cultivation management of the crop to be cultivated, the fair, the linkage with the smartphone application, IoT, chicken farming using AI, quality control of the eggs and freshness management become possible, and "CalaGARDEN",
Access to the culture of the subculture HP etc. which guide reutilization of the container 10 after meals such as "EGGGARD", "Tamago garden", etc. Access to the game for cultivation etc. which adjust the timing and quantity of watering and fertilization etc. Can do it.

The first coating step S20, the edge coating step S50, and the second coating step S80 may be performed multiple times each. Thereby, the coating layer 16
, 17 can be formed thick in multiple layers, and the strength of the eggshells 21, 22 can be increased. In addition, the first coating step S20, the edge coating step S50, and the second coating step S80 may be performed multiple times with different types of coating agents. That is, the coating layers 16 and 17 may be formed in multilayers with different types of coating agents.

Furthermore, after performing the second splitting step S60 prior to the first splitting step S30 in the first splitting step S30 and the second splitting step S60, and cutting out the eggshell 23 from the eggshell 20, the first splitting step S60 is performed. S3
0 may be performed to cut the eggshell 22 from the eggshell 20 from which the eggshell 23 has been cut away to form the eggshell 21 and to provide the main body portion 11 and the pedestal portion 12.

The tip end of the adsorber 604 of 02 is configured to protrude toward the tip end.

A pressure sensor 607 for sensing the pressure received by the cutting blade bodies 102K and 102L is attached to the proximal end side of the rotating shaft 3005K. The pressure sensor 607 is formed in a substantially cylindrical shape and is attached to the tip side of the motor 301K in a state of being inserted into the rotation shaft 305K. Specifically, in the pressure sensor 607, the cutting blade bodies 102 K and 102 L are eggshells 20 of the egg 30.
When detecting the reaction force received from the pedestal main body 13 and cutting the eggshell 20 of the egg 30 or the pedestal main body 13 with the cutting blade main bodies 102K and 102L, the eggshell 20 or pedestal main body 1
3 is a pressure sensing device for preventing damage such as cracking or crushing. Furthermore, when the pressure sensor 607 breaks the eggshell 20 of the egg 30 with the egg breaking machine 100K, the case 30 breaks the egg 30 or the case body of the worker such as a child carelessly. It also prevents the danger of entering the inside of the vehicle. The pressure sensor 607 is provided with the cutting blade body 102 K, 10.
When the reaction force received by the 2L from the eggshell 20 of the egg 30 or the pedestal main body 13 exceeds a predetermined value, it is connected to a control unit 609 having a function of generating an alarm sound and causing the operator to recognize, for example. ing.

Here, the mode switch 106 rotates the mode switch 106 in the circumferential direction, whereby the eggshell 20 of the egg 30 of the egg 30 in the cutting blade main body 120K is controlled by the control unit 609.

The cut pieces of the eggshell 20 can be used, for example, as a fertilizer for plants.

The control unit 609 also senses the pressure sensor 607 from the state where the pressure sensor 607 senses the pressure received when cutting the eggshell 20 of the egg 30 and the pedestal body 13 with the cutting blade bodies 102K and 102L. It has an automatic stop function of stopping the supply of power to the motor 301K and stopping the rotational driving of the cutting blade bodies 102K and 102L when the pressure is reduced instantaneously. As a result, it is possible to prevent the operator's hand holding the case body 303 from being damaged when the egg 30 breaks or the like in the egg breaking operation by the egg breaking machine 100K.

Furthermore, the control unit 609 may control the rotational speeds of the cutting blade bodies 102K and 102L according to the pressure sensed by the pressure sensor 607. For example, the cutting blade body 102K, 102
The rotational speed is gradually increased as the cutting of the eggshell 20 of the egg 30 and the pedestal main body 13 progresses in L, and when the cutting of the eggshell 20 of the egg 30 and the pedestal main body 13 is completed, the cutting blade main body 1
The rotational speed of 02K and 102L is gradually lowered and then stopped, and a whistling voice such as "Piyopiyo" is generated to notify the operator of the completion of the work. As a result, the split egg machine 1
The safety of 00 K can be enhanced, and the worker can be prevented from touching the cutting blade bodies 102 K and 102 L and causing injury or the like.

Note that various sensors can be used as the pressure sensor 607, as long as it is a sensor that can sense the received pressure, such as a pressure sensor using a MEMS, for example.

Furthermore, on the inner peripheral surface of the case body 303, the blade 112K of each cutting blade body 102K, 102L
, And 112L, a position sensor 608 is attached as a direction detection device for detecting the direction of the eggshell 20 or the pedestal main body 13 of the egg 30. The position sensor 608 is a case body 3

The position sensor 608 is provided with the blades 112K of the cutting blade bodies 102K and 102L,
When the central axis of the eggshell 20 or the pedestal main body 13 is positioned on the central axis of 112 L, for example, a control unit 609 having a function of generating an alarm sound and causing a worker to recognize it is connected.

From this, the cutting blade main body 102 K, 102 L is the egg shell 20 of the egg 30 or the pedestal main body 13
The direction of the eggshell 20 or the pedestal main body 13 of the eggs 30 can be accurately aligned when pressed against. Therefore, since alignment at the time of cutting eggshell 20 or pedestal main part 13 of these eggs 30 can be made easy, eggshell 20 or pedestal main part 13 of these eggs 30 is possible.
The cutting work by the cutting parts 31 and 32 can be facilitated with high accuracy.

Further, as the control unit 609, the cutting blade main body 102 is detected by the position sensor 608.
The position of the eggshell 20 of the egg 30 with respect to K and 102 L is the reference position (the position where the central axes coincide)
In the case where it deviates from the above by generating a buzzer sound and stopping the rotation of the cutting blade bodies 102K and 102L, guidance of the cutting blade bodies 102K and 102L to the eggshell 20 of the egg 30 can be performed to an appropriate position. It becomes.

Furthermore, the control unit 609 detects the position of the cutting blade body 102K, the cutting blade body 102K,
Only when the position of the eggshell 20 of the egg 30 with respect to 102L is located within a certain range from the reference position, the intake mechanism 402K is driven and the cutting blade bodies 102K and 102L are rotationally driven to adsorb the eggshell 20 of the egg 30 It is good also as composition which enables adsorption to adsorption object 604 of mechanism 602, and can perform cutting operation by cutting blade main part 102K and 102L. From this, it becomes possible to perform not only the minimization of the cutting pieces generated at the time of cutting by the cutting blade bodies 102K and 102L, but also the cutting work by the cutting blade body 102L for creating the pedestal portion 12 from the pedestal body 13 more accurately. .

In addition, the control unit 609 is at a natural position in a state where the operator holds the holding body 101H,
Turning the split egg machine 100H diagonally, in this state, the cutting blade body 102K, 102 of the split egg machine 100H
When L is applied to the eggshell 20 of the egg 30, it may have a camera shake correction function for guiding an accurate position by detection by the position sensor 608.

Then, when the pedestal main body 13 is cut and opened by the cutting portion 32 with the cutting blade main body 102L of the split egg machine 100K, the holder 200K is used. The holder 200 K is a pedestal body 1
It has an outer diameter dimension on the proximal side of 3, that is, an outer diameter dimension equal to the diameter dimension of the cut portion 31. Further, the holder 200K has a height dimension larger than the distance dimension between the tip of the case body 303 and the tip of the cutting blade main body 102L in the axial direction of the split-off machine 100K. Furthermore, the holder 200 K has a cylindrical portion 201 having an inner diameter smaller than the outer diameter of the pedestal main body 13.
It is formed in the bottomed cylindrical shape comprised by K and the bottom face part 202K which obstruct | occludes the bottom part side of this cylindrical part 201K.

In addition, the structure of the split-off machine 100K is one egg 30 by the cutting blade main bodies 102K and 102L.
The configuration may be any configuration as long as an eggshell 21 serving as the main body 11 and an eggshell 22 serving as the pedestal 12 can be formed from the eggshell 20 of the above.

Next, the manufacturing method of the container 10 using the split-off machine 100K comprised in this way is demonstrated.

First, the switch 105K of the split-off machine 100K is turned on to set the mode switch 106 to the large diameter mode to drive the intake mechanism 400K. Then, the cutting blade main bodies 112K and 112L are rotationally driven in conjunction with the rotational driving of the rotational shaft 305K. At the same time, air is sucked into the suction pipe main body 603 from the tip end side of the suction body 604 of the suction mechanism 602 by suction by the suction mechanism 400K, and air between the case body 303 and the cutting blade main body 112K is sucked. These inhaled air flows from the exhaust port 601 of the case body 303 to the case body 3.
Exhausted to the outside of 03.

In this state, the operator grips the case body 303 of the egg breaking machine 100K, and this egg breaking machine 100K
The egg breaking machine 110 K is brought close to the egg 30 so that the air chamber side center of the egg 30 is located at the center of the adsorbing body 604 of the suction mechanism 602 of FIG. At this time, the blade 11 of the cutting blade body 102K, 102L
When the central axis of the eggshell 20 of the egg 30 is positioned on the central axis of 2 K, 112 L, it is determined to be the reference position and the position sensor 608 acts to generate, for example, an alarm sound.
Accurate alignment of the egg 30 with respect to K and 112L is possible.

After that, the egg breaking machine 110K is further brought close to the egg 30, and the adsorption mechanism 6 of the egg breaking machine 100K
The adsorber 604 of 02 is adsorbed at the center position on the air chamber side of the egg 30. At this time, the intake mechanism 40
The air between the case body 303 and the cutting blade body 112K is sucked in by the intake air at 0 K, and the sucked air flows from the exhaust port 601 of the case body 303 to the case body 303.
Exhaust to the outside.

Thereafter, when the adsorber 604 of the suction mechanism 602 of the split-off machine 100K is pressed against the egg 30, the suction body 604 of the suction mechanism 602 is elastically deformed and the blade 112K of the cutting blade main body 102K
Contact the surface of the eggshell 20 of the egg 30. At this time, the cutting blade main body 102 K is pressed against the eggshell 20 of the egg 30 because the center of the eggshell 20 side of the eggshell 20 of the egg 30 is positioned and held at the center of the adsorber 604 of the adsorption mechanism 602. Since the orientation and position of the eggshell 20 can be precisely matched at the time, the alignment at the time of forming the opening 14 in the eggshell 20 of the egg 30 is optimized, and the wrong entry at other than the optimum position, ie, at the wrong position. Disconnection can be prevented. Therefore, the operation of forming the opening 14 in the eggshell 20 of the egg 30 can be performed easily and precisely.

Furthermore, when this split egg machine 100K is pressed against the egg 30, the blade 1 of the cutting blade main body 102K
The surface of the eggshell 20 of the egg 30 is cut at the cutting portion 31 at 22K. At this time, cutting pieces generated when cutting the eggshell 20 of the egg 30 by the cutting blade main body 102K are sucked between the case body 303 and the cutting blade main body 112K, and are collected by the dust collector 107 in the intake mechanism 400K. It will be collected.

As a result, the pedestal main body 13 is adsorbed to the adsorbing member 604 of the adsorbing mechanism 602, and the eggshell 21, that is, the main body portion 11 is formed. At this time, the pressure sensor 607 senses the pressure that the cutting blade body 102K receives from the eggshell 20 of the egg 30, and when this pressure exceeds a predetermined value, an alarm sound is generated, for example. Egg shell 20 of the egg 30 in the main body 102 K
When cutting, the cracking and crushing of the eggshell 20 are prevented.

Then, after the main body portion 11 is removed from the cracking machine 100K, the mode switch 106 is operated to set the small diameter mode, and then the holder 200K is centered on the pedestal main body 13 adsorbed by the suction mechanism 602 of the splitting machine 100K. The split machine 100K is brought close to the holder 200K such that the center of the frame is located. At this time, when the central axis of the holder 200K is positioned on the central axes of the cutting blade bodies 102K and 102L, the position sensor 608 acts to generate, for example, an alarm sound, and the holder 200K for these cutting blade bodies 112K and 112L Accurate alignment is possible.

Furthermore, the pedestal main body 13 adsorbed by the adsorption mechanism 602 of the split-off machine 100 K is held by the holder 20.
As it approaches the upper surface of 0 K, the adsorbing body 604 of the adsorption mechanism 602 is further elastically deformed, and the blade 112 L of the cutting blade main body 102 L contacts the surface of the pedestal main body 13. Breaking machine 1 from this state
As 00 K is pressed against the holder 200 K, the surface of the pedestal main body 13 is cut at the cutting portion 32 by the blade 122 L of the cutting blade main body 102 L. As a result, the adsorber 604 of the adsorption mechanism 602
Thus, the eggshell 23 is adsorbed to form the eggshell 22, ie, the pedestal 12. At this time, the pressure received by the cutting blade main body 13 from the pedestal main body 13 is sensed by the pressure sensor 607, and when the pressure exceeds a predetermined value, an alarm sound is generated, for example. At the time of cutting the pedestal main body 13, cracking, crushing, and the like of the pedestal main body 13 are prevented.

As a result, the eggshell 2 of the egg 30 is cut by the cutting operation of the eggshell 20 of the egg 30 by the split-off machine 100K.
The main body 11 and the pedestal 12 are formed from zero. Therefore, the blades 11 having different outer diameter dimensions
The main body portion 11 and the pedestal portion 12 can be manufactured from the eggshell 20 of the egg 30 only with one spliting machine 100K without using a plurality of splitting machines having 2K and 112L.

Furthermore, when a small hole is made in a part of the eggshell 20 of the egg 30 to form an egg art material in the split-off machine 100K, the switch 105K of the split-off machine 100K is turned on and the mode switch 106 is in cone mode Make it Then, by driving the motor 301K, the pyramid material 602K advances from the position accommodated in the suction pipe main body 603 to a position projecting to the tip side more than the blade 112K of the cutting blade main body 102K. In this state, a small hole can be made in the eggshell 20 of the egg 30 by penetrating the pyramidal material 602 K to the central position of the air chamber side of the eggshell 20 of the egg 30 or the like. Then, the eggshell 20 is removed by removing the egg solution in the eggshell 20 from the small hole.
Can be used as a material for egg art.

After that, the switch 105K of the egg breaking machine 100K is turned off. Then, by driving of the motor 301K, the pyramid material 602K is retracted from the position protruding from the blade 112K of the cutting blade body 102K to the tip end side to the position accommodated in the suction pipe body 603. The pyramid material 602K is accommodated in the Therefore, except when using the pyramid material 602K, the pyramid material 602K is accommodated in the suction pipe main body 603, so that it is possible to prevent the worker from being damaged due to the projection of the pyramid material 602K. .

In the split egg machine 100K, an egg 3 to the center of the cutting blade main body 102K, 102L.

Further, as in still another embodiment shown in FIG. 22, it is also possible to use only the conical material 602N having a sharpened tip concentrically with the center of the cutting blade body 102N as a positioning mechanism. In this case as well, before cutting the eggshell 20 of the egg 30 with the cutting blade main body 102N, the pyramidal material 602N is penetrated to the center position of the eggshell 20 of the egg 30 to make the egg 30 against the center of the cutting blade main body 102N. The center of the eggshell 20 can be positioned. As a positioning mechanism,
A plurality of radial cuts may be inserted at the center position of the disc-like elastic sheet.

Furthermore, in the split-off machine 100 K, the cutting blade body 102 is sucked by the suction mechanism 400.

[Jig for drying]
Next, with reference to FIG. 25 and FIG. 26A, the drying jig 900 used in the manufacturing process of the container 10 according to the embodiment of the present invention will be described in detail. Also in the following explanation,
Refer to FIGS. 1 to 4 as appropriate.

The drying jig 900 according to the present embodiment is a drying tray for drying the eggshells 21 to be a plurality of, for example, a total of 12 body parts 11, and mainly includes the outer surface 21 a of the eggshells 21.
It is used to naturally dry the coating agent applied to the like. Specifically, the drying jig 900 includes a rectangular flat plate 901. A plurality of, for example, a total of 12 elongated cylindrical rod-like columns 902 are vertically attached to the plate 901. The support columns 902 are in a state in which the axial direction of the support columns 902 is in the vertical direction.
The lower end portion, which is one end portion of 02, is fixed by inserting it onto the plate 901 or the like.

Further, the columns 902 are arranged in a lattice at equal intervals on the plate 901, and the columns 902 are arranged at the upper end side of the columns 902 as shown in FIG. The outer surface 21a of the respective eggshells 21 does not contact each other, that is, they do not rub against each other in a state where the tips of the columns 902 are inserted into the eggshells 21 and the eggshells 21 are locked to the columns 902. For example, it is attached at intervals of about 25 mm to 30 mm. That is, the support columns 902 are attached at intervals of about twice the maximum diameter dimension in the radial direction orthogonal to the long axis direction of the egg 30.

Furthermore, buffer members 903 for preventing the occurrence of breakage or breakage of the eggshell 21 locked to the columns 902, that is, damage, are removably attached to the tip end of these columns 902, respectively. These buffer members 903 are formed of, for example, an elastic material such as a sponge or a rubber in a hemispherical shape having a diameter of, for example, about 15 mm. The buffer members 903 are formed to have an outer diameter smaller than the diameter of the opening 14 of the eggshell 21 and larger than the diameter of the opening 15 of the eggshell 22. And these buffer members 903 are flat portions 90.
The upper end portion of the support column 902 is inserted at the center position of the flat portion 904 and is concentrically fixed to the upper end portion of the support column 902 with the four sides facing downward. The spherical portions 905 of these buffer members 903 are in the state that the eggshell 21 is locked by the support 902.
A shape that prevents rotation and shaking of each eggshell 21 whose center of rotation is the upper end portion 02 is formed in a spherical shape substantially equal to the shape of the inner surface 21b on the end side of the eggshell 21.

Therefore, when the coating agent applied to the outer surface 21 a and the like of the eggshell 21 to be the main body 11 is naturally dried, first, the openings 14 of the eggshells 21 are directed downward. Thereafter, the upper end of the column 902 of the drying jig 900 is inserted into the opening 14 of each eggshell 21 so that the portion of the inner surface 21b of each eggshell 21 facing the opening 14 is buffered. The spherical portion 905 of the member 903 is concentrically positioned and mounted. In this state, the coating agent applied on the outer surface 21 a or the like of each eggshell 21 held by the drying jig 900 is naturally dried by leaving it naturally for a predetermined time which has been determined in advance. Can.

In the case of this natural drying, the eggshells 21 held by the respective columns 902 rotate or shake around the tip of the respective columns 902 due to the effects of an impact, wind, etc. Also, since the pillars 902 are attached at intervals such that the outer surfaces 21a of the eggshells 21 do not contact each other, the outer surfaces 21a of the eggshells 21 do not contact each other. Therefore, breakage such as cracking or chipping of the eggshells 21 which may occur when the outer surfaces 21a of the eggshells 21 come in contact with each other can be appropriately prevented. At the same time, it is possible to prevent the peeling off of the coating agent, the waving of the surface, and the like that may occur when the coating agents applied to the outer surface 21 a of the eggshell 21 come in contact with each other. Therefore, the coating agent applied to the outer surface 21a of the eggshell 21 can be dried with a uniform thickness and a smooth surface, so that the coating agent can be easily dried appropriately.

Further, the opening 15 of the eggshell 22 to be the pedestal 12 is directed upward, and in this state, the upper end of the column 902 of the drying jig 900 is inserted into the cutting portion 31 of the eggshell 22. Thus, the spherical portion 905 of the buffer member 903 can be placed opposite to the inner surface 22 b of each eggshell 22 so as to be concentric with the opening 14 of each eggshell 22. . Therefore, in this state, the coating agent applied to the outer surface 22a or the like of each eggshell 22 held by the drying jig 900 is properly stored by naturally standing for a predetermined time. It can be naturally dried. Therefore, even in the pedestal portion 12, the coating agent applied to the outer surface 22 a or the like of the eggshell 22 serving as the pedestal portion 12 can be easily dried appropriately.

In the drying jig 900 shown in FIGS. 25 and 26A, the buffer member 903 has a hemispherical shape, but for example, a flat plate having a square shape in plan view like the buffer member 903R shown in FIG. 26B. It may be in the form of That is, if the shape of the buffer members 903 and 903R is a shape that allows the main body portion 11 and the pedestal portion 12 to be naturally dried appropriately, such as an umbrella that can be opened at the time of use as shown in FIG. A plurality of cushioning members 903S having a shape, a coil-shaped cushioning member 903T whose diameter is gradually reduced toward the tip end as shown in FIG. 27B, and a plurality of, for example, from tip ends of columns as shown in FIG. It may have any shape such as a buffer member 903U having a shape in which three locking pieces 906A project obliquely upward at equal intervals. And this shock absorbing member 90
In 3U, a connecting piece 906B having a triangular shape in plan view for connecting these three locking pieces is provided. The connecting piece 906 B is provided in a horizontal straight line, and a total of three locking pieces 90 are provided.
Each of 6A is connected in a horizontal position. The drying jig 900 may be placed in a heating device such as a steam convection oven, for example, to heat and dry the eggshells 21 and 22 held by the drying jig 900.

Next, another drying jig 900V will be described in detail with reference to FIG. In the following description, FIGS. 1 to 4 will be referred to as appropriate.

The drying jig 900V according to the present embodiment basically has the same configuration as the above-described drying jig 900, but between the pillars 902 for drying the eggshell 21 to be the main body portion 11, Struts 907 for drying the eggshells 22 to be the pedestal portion 12 are provided at regular intervals in a lattice shape. Then, a bifurcated locking piece 908 is provided at the tip of each of the columns 907, and one of the tips of each locking piece 908 is inserted from the cutting part 31 side of the eggshell 22. Then, the inner surface 22b of the eggshell 22 is locked so that the eggshell 22 can be dried.

That is, each support column 902 is formed longer than the support columns 907, and even when the eggshell 22 is locked to one of the locking pieces 908 of the support columns 907, the buffer member 903 of each support column 902. The respective eggshells 21 held in the above are formed in a length dimension that does not come in contact with the respective eggshells 22. Furthermore, when the eggshells 22 are locked to the locking pieces 908 between the locking pieces 908 of the columns 907, the eggshell 22 is prevented from coming into contact with the columns 907, A connecting piece 909 is attached to prevent damage.

The connection piece 909 is formed in a V-shape in a side view reverse V with a central portion protruding upward,
Both end portions of the connection piece 909 are connected to and attached to a substantially central position in the longitudinal direction of each locking piece 908. Then, when the connecting piece 909 inserts the tip of either one of the locking pieces 908 from the side of the cutting portion 31 of the eggshell 22 and locks the inner surface 22b of the eggshell 22,
The bent top portion 909A of the connecting piece 909 contacts and locks the inner surface 22b of the egg shell 22. The locking of the top portion 909A and the locking portion 908 causes the egg shell 22 to swing temporarily. For example, the eggshell 22 is locked so as not to contact or get caught in the support 907. Note that the connecting piece 909 has, for example, an arc shape projecting upward, as long as the shape does not contact or get caught in the support 907 even if the eggshell 22 shakes.
It may have any shape.

Therefore, the eggshell 2 is placed on each of the buffer members 903 of the columns 902 of the drying jig 900V.
1 by holding the eggshell 22 and holding the eggshell 22 in one of the locking pieces 908 and the connecting piece 909 of each support column 907 of the drying jig 900V. Since the eggshell 22 to be the pedestal 12 can be dried, the usability of the drying jig 900V can be improved.

[Example]
Next, an example of the coating agent used as the coating layers 16 and 17 in the manufacturing process of the container 10 according to the present invention will be described in detail. In the following description, FIGS. 1 to 4 will be referred to as appropriate.

(Example 1: 7.5 wt% pullulan aqueous solution)
First, as a pullulan aqueous solution used as a coating agent for the first layer 18 of the coating layer 16, pullulan test solution 1 having a content of pullulan (manufactured by Hayashibara Co., Ltd.) of 7.5% by weight with respect to pure water is prepared and tested In a container for storage. At the same time, a shellac liquid (Lack Grace 32E: manufactured by Nippon Shellac Industrial Co., Ltd.) in which shellac and ethanol were mixed at a weight ratio of 32: 68 was prepared. At this time, the outside temperature was 25 ° C., and the humidity was 65%.

Next, a plurality of, for example, two eggshells 21 cut at the cutting portion 31 are prepared to form eggshells A and B. The openings 14 of the eggshells A and B are directed downward, and the openings 14 of the eggshells A and B are At the opening edge,
The openings 14 of the eggshells A and B were immersed in the pullulan test solution 1 for 5 seconds so that the pullulan test solution 1 adhered to a width of about 5 to 10 mm.

Thereafter, the degree of adhesion of the pullulan test solution 1 adhering to the opening 14 of each eggshell A, B is visually confirmed, and when the pullulan test solution 1 is excessively adhered, the eggshells A, B Opening 14
The amount of pullulan test solution 1 adhering to the opening 14 of the eggshells A and B was adjusted by wiping the pullulan test solution 1 adhering to the above.

In this state, with the openings 14 of the respective eggshells A and B directed downward, the respective eggshells A and B are locked by pillars (not shown), and for example, an oven (confectionery oven: World Seiki Co., Ltd. The pullulan test solution 1 attached to the opening 14 of each eggshell A, B was heated and dried at a temperature of 120.degree. At this time, the pullulan test solution 1 adhering to the outer surface 21a of the eggshells A and B moves downward by the weight of the pullulan test solution 1 itself, and the pullulan test solution at the end face 21c of each eggshell A and B Since the thickness of 1 becomes thick, pullulan test solution 1 thinly attached to the outer surface 21a of eggshells A and B is dried by heating and drying for about 2 minutes, but each eggshell A
B, the pullulan test solution 1 attached thickly to the end face 21c has 6 eggshells A until it is dried.
It took 30 seconds for a minute, and 7 minutes and 30 seconds for an eggshell B.

Then, the opening 14 of each eggshell A, B in which the pullulan test solution 1 is dried and the first layer 18 is formed at the opening edge of the opening 14 faces downward, and the opening 14 of the opening 14 of each eggshell A, B At the edge, about 5 to 1
The openings 14 of the eggshells A and B were immersed in the shellac liquid for 5 seconds so that the shellac liquid was attached to a width of about 0 mm. Therefore, the shellac liquid adheres to the entire surface of the first layer 18 formed at the opening edge of the opening 14 of each eggshell A, B.

Thereafter, the degree of adhesion of shellac liquid adhering on the first layer 18 of each egg shell A, B is visually confirmed, and if the shellac liquid is excessively adhered, the egg shell A, B The amount of shellac liquid adhering on the first layer 18 of each eggshell A, B was adjusted by wiping the shellac liquid adhering on the first layer 18 or the like.

In this state, with the openings 14 of the respective eggshells A and B directed downward, the respective eggshells A and B are locked by pillars (not shown), and for example, an oven (confectionery oven: World Seiki Co., Ltd. The shellac liquid on the first layer 18 of each eggshell A, B was dried by heating at a temperature of 120.degree. Also at this time, the shellac liquid adhering to the outer surface 21a of the eggshells A and B moves downward by the own weight of the shellac liquid itself, and the end face 21c of each eggshell 21
The shellac solution thinly attached to the outer surface 21a of the eggshell 21 is dried by heating and drying for about 1 to 2 minutes because the thickness of the shellac solution at this time is thick.
Shellac liquid thickly attached to c took 5 minutes to dry. As a result, the first layer 18 and the second layer 19 are formed at the opening edge of the opening 14 of each eggshell A, B to form the coating layer 16.

(Examples 2 to 5: 12.5 to 25 wt% pullulan aqueous solution)
Next, as a pullulan aqueous solution used as a coating agent for the first layer 18, the content of pullulan changes to 12.5% by weight, 15.0% by weight, 17.5% by weight, and 25% by weight with respect to pure water The prepared pullulan test solutions 2 to 5 were prepared. And these pullulan test solutions 2
The time required for drying the pullulan test solutions 2 to 5 was measured as Examples 2 to 5 in the same manner as in Example 1 above.

As a result, as shown in Table 1, in the case of Pullulan test solution 2 in which the pullulan content rate is 12.5% by weight with respect to pure water, eggshell A is 9 minutes until pullulan test solution 2 is dried, Eggshell B took 9 minutes and 30 seconds (Example 2). In addition, with pullulan test solution 3 having a pullulan content of 15% by weight, it took 12 minutes for eggshell A and 12 minutes and 30 seconds for eggshell B to dry (Example 3). Furthermore, pullulan test solution 4 with a pullulan content of 17.5% by weight
In this case, it takes 14 minutes for eggshell A and 15 minutes and 30 seconds for eggshell B to dry (Example 4), and pullulan content is 25% by weight. It took 19 minutes for eggshell A and 18 minutes for eggshell B (Example 5).

The time required for the shellac liquid laminated on the surface of the first layer 18 formed on the outer surface 21a of the eggshells A and B to dry is 5 minutes in any of Examples 1 to 5 and is constant. It was time for

As a result of Examples 1 to 5 above, when the content ratio of pullulan to pure water is higher than 17.5% by weight, the adhesion amount of pullulan to eggshell 21 becomes too large, and the pool of pullulan aqueous solution on end face 21c of eggshell 21 The drying time of the aqueous solution of pullulan adhered to the eggshell 21 becomes longer. On the other hand, the content ratio of pullulan to pure water is 12
. If it is lower than 5% by weight, the adhesion of pullulan to the eggshell 21 becomes too low, and the first layer 18 tends to peel off the outer surface 21a of the eggshell 21 and the like.

Therefore, it was found that the content of pullulan to pure water is preferably 12.5% by weight or more and 17.5% by weight or less from the viewpoint of adhesion to eggshell 21 and drying time. Furthermore, it was found that setting the content of pullulan to pure water to 15% by weight is particularly preferable because appropriate adhesion to the eggshell 21 can be secured and drying can be performed in a relatively short time.
