[Industrial application field]

This invention relates to foam containers for freezing and cold storage. Refrigerating for freezing frozen items, or for cooling and preserving pre-chilled items. Regarding a foam container for cold storage.

0002

[Conventional technology]

In recent years, foamed wood has been used for transportation of fresh fish due to its light weight, insulation properties, and stability of supply. Foam containers molded from fat are used, and traditional wooden boxes are almost never used. The current situation is that it is disappearing. However, freezing salted fish such as salted mackerel Wooden boxes are the mainstream for storage and transportation, and foam containers are rarely used. The reason The reason is that foam containers are more expensive than wooden boxes, and salted mackerel, which is considered to be a lower grade fish than fresh fish, is more expensive than wooden boxes. Although it is sometimes considered unsuitable due to cost, it is technically possible to preserve salted mackerel by freezing. This was due to the fact that foam containers suitable for transporting these materials had not yet been developed. More details The distribution route for salted mackerel is special and complicated, so it cannot withstand long-term transportation. There are strict requirements for the strength of the container used for this purpose, and in addition to freezing it, it must also be This is because there was a need to be able to refreeze it. In other words, foamed resin Conventionally, frozen items are stored in foam containers because of their high thermal insulation properties. There are no foam containers that are suitable for freezing or refreezing. It was a long time ago.

0003 For this reason, when it comes to fresh fish, etc., for which foam containers have traditionally been used, it is necessary to freeze them separately. After putting it in a container and freezing it, I put the frozen fresh fish in a foam container, It was kept cold to prevent it from thawing. However, the labor costs associated with replacement work These factors can be ignored for products with high commercial value, such as fresh fish, but they affect the product price. For salted fish such as mackerel with low salt content, it will be reflected in the cost and there will be no need to replace it. However, due to the cost, it was not possible to use such containers.

0004 On the other hand, wooden boxes lack airtightness, so even if salted mackerel is stored in a freezer, etc. Even if there was, there was a problem that the color would start to change after about a month. In addition, the wooden box is made from salted mackerel. It has the advantage of sucking up the liquid juice etc., but the wooden box that sucked the liquid liquid etc. is unhygienic. However, they could not be reused and were all incinerated. Because of this, deforestation Nowadays, disposable wooden boxes are becoming a social problem. In recent years, it has become difficult to supply wooden boxes.

[0005] Therefore, the inventors of the present invention took advantage of the advantages of foam containers while storing the items to be frozen in foam containers. Efforts have been made to obtain foam containers that can be frozen and easily refrozen. As a result of repeated research, we found that in Utility Application No. 2-85180, etc. We proposed a foam container for freezing and cold storage that has air vents closed. With these ideas, I was able to solve the above problem.

[0006]

[Problem that the idea aims to solve]

However, among these foam containers for freezing and cold storage, it is difficult to store frozen items inside the container body. Containers that are lined up in only one layer and sealed with lids do not allow the items to be frozen to be pressed against each other. It is suitable for maintaining quality because it will not be deformed by Although it has the advantage of being able to process frozen food without wasting it, the cost of containers is high, Moreover, there was a problem in that each container was large and bulky. On the other hand, foaming for freezing and cold storage Inside the container, the items to be frozen are stored in two layers and sealed with a lid. This type of container is relatively inexpensive to manufacture, and moreover, it is possible to use two single-stage containers as described above. Although it has the advantage that the bulk is lower overall than stacking, it is possible to The objects to be frozen in the lower tier are pressed and deformed, and the objects to be frozen in the upper tier are pressed and deformed. There was a problem in that the material was deformed to follow the external shape of the object to be frozen. Furthermore, 2 Stacked foam containers for freezing and cold storage have high side walls, so they work in a direction perpendicular to the side walls. The problem was that it was weak against force and easily cracked. Therefore, the inventors further worked hard to As a result of repeated research, we came up with this idea.

[0007]

[Means to solve the problem] The gist of the foamed container for freezing and cold storage according to the present invention is that the container is made of foamed resin. A foam container for freezing and cold storage, with the inside of the main body divided into upper and lower layers by partition plates. The container includes an engagement member that is engaged with an outer peripheral portion of the partition plate on the inner surface of the side wall of the container body. A mating portion is provided, and a partition plate that is engaged with the engaging portion is made of a rigid member. It is in what is being done.

[0008] In addition, the gist of the foamed container for freezing and cold storage according to the present invention is that it is made of foamed resin. The opening of the container body is sealed by the lid or the bottom of the stacked container bodies. The foam container includes a vent opening in a side wall of the container body, and a vent opening in a side wall of the container body. It is equipped with a door body that closes the mouth, and the mouth edge of the vent that is in contact with the door body or the mouth edge of the vent that is in contact with the door body. A convex portion is provided on one of the end faces of the door body, and a convex portion is provided on the other side as necessary. A concave portion is provided, and the elastic force of the member constituting the convex portion or concave portion allows the door body to pass through. In a foam container that is locked to an air port and is configured to close the air port, the container main body In addition to providing a partition plate made of a rigid member that divides the inside of the body into upper and lower levels, By forming an engaging part on the inner surface of the side wall of the container body to be engaged with the outer periphery of the partition plate. be.

[0009] Furthermore, in such a foam container for freezing and cold storage, an engaging portion is provided in the vent and the door body. Then, the door body locked to the vent moves along the edge of the vent due to the engagement of the engaging part. The reason is that it is made so that it cannot slide.

0010 In addition, in such a foam container for freezing and cold storage, the fish body placed on the partition plate is The reason is that a stepped portion is formed that can be adapted to the shape of.

[0011]

[Effect]

In the foamed container for freezing and cold storage of the present invention, the object to be frozen or the object to be kept cold is vertically stacked. The container body is formed to a size that can be stored in several tiers, and the inner surface of the side wall of the container body is provided with an engaging portion to which the outer periphery of a partition plate that partitions the interior into upper and lower parts is engaged. It is being On the other hand, the partition plate that is engaged with the engaging part of the container body is of the same type as the container body. Or, it is composed of rigid members made of different materials, and this partition plate The interior of the container body is horizontally partitioned by. First, place the frozen material at the bottom of the container body. After the items are put in, the partition plate is put in and engaged with the engaging part, and the inside of the container body is closed. The sections are divided horizontally. Furthermore, items to be frozen are placed on top of this partition plate, and necessary If necessary, a lid is placed on the container body, and a binding string is hung. Here, the partition The objects to be frozen placed on the board are received by the rigid partition plate, and the partition No load is applied to objects to be frozen placed under the plate. Therefore, the lower part The objects to be frozen and the objects on the upper stage are not pressed against each other, and their shapes are not changed or Rui will never be crushed. In addition, the rigid partition plate allows the main body of the container to be The side wall of the container is reinforced, making it a stronger container and preventing it from deforming or breaking. I can do it.

0012 Next, in a foam container equipped with a vent, the bottom of the container body and the partition plate should be After placing the items to be frozen on top of the container, a lid is placed over the container body, or multiple As the container bodies are stacked, a lid is placed on the top container body, and then the entire container body is The body is bound with binding cords. If the top opening of the container body does not close to the lid or stacked containers, Freeze or pre-cool the items to be frozen inside the container while it is sealed at the bottom of the container. The door body is removed from the vent provided in the container body to prevent the vent from opening It will be done. The vent is preferably located substantially opposite the container body and Cold air flows smoothly through the vents that are opened, and is separated by the partition plate inside the foam container. The cut and placed frozen items are quickly frozen, or the frozen items are quickly pre-cooled. be done. After the items to be frozen are frozen or pre-cooled, a door body is attached to the vent. Ru. The door body uses elastic compression deformation of the container body and door body members from the outside of the container body. inserted into the vent, and formed on either the edge of the vent or the door body, or both. The recess or protrusion allows the door body to be tightly locked to the vent, and the vent is completely closed. will be stopped.

[0013] This door body allows room-temperature air to freely flow inside the foam container during subsequent storage and distribution processes. The cold storage effect is enhanced by preventing the water from entering or leaving the room. In addition, this door body allows foaming Since the airtightness of the container is improved, the frozen items stored in the container will not be oxidized. This can greatly extend the period of time it takes for the color to change. Furthermore, it takes Frozen items stored in foam containers for freezing and cold storage are thawed during the distribution stage. If it becomes necessary to refreeze or pre-cool the item again, , the door body is removed from the vent provided in the container body, and the door remains tied together. The foam container for freezing and cold storage is placed in the freezer. Do not open the inside of the foam container. Cold air flows in through the vents, and the cold air refreezes the frozen items. Otherwise, the items to be kept cool are pre-cooled.

[0014] Such foam containers for freezing and cold storage are delivered to markets, the lids are removed, and the containers are put on display. After being removed, the container body may be transported as is. At that time, ventilate the container body. If the worker's arm touches the door that is locked in the mouth, or if the container body vibrates or The door may be roughly deformed and a force may be applied in the direction of lifting the door that is locked to the vent. There is. However, in response to this force, the door body is not engaged with the vent by the engagement part. Because of this, it will not slide along the edge of the vent and the vent will open. It won't happen. Therefore, if the vent is accidentally opened, the objects to be frozen or This eliminates the possibility of cold items slipping down. Furthermore, the door body can be tightly attached to the vent due to the engaging part. By being locked and integrated with the side wall, it can be lowered by providing ventilation holes. The strength of the side walls can be increased. In addition, the inside of the container body is divided into multiple upper and lower levels. The partition plate receives the force acting perpendicularly to the side wall, improving the strength of the container body. I am made to do so.

[0015] In addition, not only the bottom of the container body of such foamed containers for freezing and cold storage, but also the container itself. The partition plate that is engaged with the engaging part in the By forming the desired shape, especially the steps, the shape of the fish can be adjusted and frozen. can be done. Furthermore, this stepped portion is provided on the side of the vent formed in the side wall of the container body. The stepped part functions as a stopper, and the vent with the door body removed. The fish to be frozen is prevented from jumping out from the container.

【Example】

Next, examples of the foam container for freezing and cold storage according to the present invention will be explained in detail based on drawings. I will clarify. In FIGS. 1 and 2, reference numeral 10 is a foam container for freezing and cold storage according to the present invention. 12 is a container body, and numeral 14 is a lid that is placed on this container body 10. Furthermore, reference numeral 15 is a partition plate that partitions the inside of the container body 10 into upper and lower parts. this container The main body 10, the lid 14, and the partition plate 15 are made of foamed polystyrene resin, foamed polyethylene, etc. Foamed polyolefin resins such as foam and foamed polypropylene, styrene and ethylene Molded with foamed resin, foamed polyurethane, etc. made by foaming a copolymer with polypropylene or propylene. However, foamed polystyrene resin is most preferred from the viewpoint of cost. Also, The container body 10, lid 14, and partition plate 15 are formed from these foamed synthetic resins alone. However, an aluminum vapor-deposited film may be used on the inside or inside of the foam container. A material that improves insulation and airtightness by laminating or inserting layers such as A box with foamed synthetic resin layered or inserted inside or inside the cardboard box. It doesn't matter what. Furthermore, these are expanded polystyrene extrusion products, so-called polystyrene extrudates. Styrene paper made by vacuum forming or polypropylene made of plastic. You may use a ball.

[0017] The opening of the container body 10 is configured to be sealed by a lid 14. The container body 10 is large enough to store several fish 17 such as mackerel side by side. It is molded in the same way. Moreover, the internal shape of the bottom 16 is at both longitudinal ends, i.e. A stepped portion 18 with a gentle slope on the short side is formed, and the fish lined up on the bottom 16 are The head of 17 is lifted up by the stepped part 18 and is shaped so that the fish shape does not collapse. There is. Note that the center portion of the bottom 16 is a flat surface, and a groove 19 is formed in this flat surface. If a large amount of liquid such as water enters the container body 10, the liquid may enter the groove 19. It is made to accumulate inside.

[0018] On the short side of the side wall 20 of the container body 10 on which the stepped portion 18 is formed, there is a A vent hole 22 is provided at a position where The ventilation hole 22 is opened above the side wall 20. The cold air flows smoothly into the container main body 10 and cools the objects to be frozen. (17) is designed to be quickly frozen. The lower part of this vent 22 The lip has a locking step 24, and the top and bottom edges of the locking step 24 are connected to both ends of the locking step 24. A groove-shaped recess 26 is provided on the outer surface of the side wall 20 on both sides of the mouth edge in the vertical direction. A recessed portion 34 and an engagement recessed portion 40 formed integrally with the recessed portion 34 are provided. ing. On the other hand, a door body 28 is inserted and fitted into the vent 22 to tightly close it. It is configured so that The door body 28 has a vent 22 locked at its lower part. The elastic force of the member is applied to the locking protrusion 30 that is locked to the step portion 24 and the groove-shaped recess 26. A filamentous convex portion 32 is provided to be locked by the filament convex portion 32 and a groove-shaped convex portion 32 The abutment plate portion 36 and the abutment plate cover the mating portion with the concave portion 26. An engagement plate 38 is integrally provided at the lower part of the portion 36.

[0019] Therefore, the locking step 24 of the vent 22 of the container body 10 and the locking protrusion of the door body 28 30 are locked with each other, and the line between the groove-shaped recess 26 on the edge of the opening and the door body 28 is The convex portions 32 of the strips are elastically compressed and deformed, and are tightly sealed by the elastic force of the foam member. be locked in. Due to this engagement and elastic force, the container body 10 is attached to the surface of the door body 28. The door body 28 does not come off from the vent 22 in response to a constant external force in the right angle direction that is applied from inside. It is made not to fall. Also, the surface of the door body 28 is made from the outside of the container body 10. In response to the applied external force, the concave portions 3 provided on both sides of the mouth edge of the vent 22 4 and the contact plate portion 36 provided on the door body 28 are brought into contact, and the door body 28 is It is prevented from entering the container body 10. Note that the contact plate of this door body 28 The opening portion 36, the locking protrusion 30, and the convex portion 32 protect the foam container 12 for freezing and cold storage. Improved cooling and airtightness. Furthermore, the engagement plate portion 38 of the door body 28 and the container book Since it is engaged with the engagement recess 40 of the body 10, the vent 22 of the container body 10 is engaged. The inserted and locked door body 28 is slid upward along the edge of the vent 22. The ventilation port 22 will not open.

[0020] Here, even when the lid body 14 is placed on the container body 10, the door body 28 is closed to the vent hole 22. It is configured so that it can be attached and detached. That is, the locking protrusion 30 of the door body 28 is ventilated. It is locked to the locking stepped portion 24 of the opening 22, and the door body 28 is rotated around the locking portion. By this, the door body 28 can be attached to the vent 22, and vice versa. can be removed from the vent 22 by pulling the top part outward. In addition When removing the door body 28 from the vent 22, the contact surface between the door body 28 and the vent 22 is removed. Even if the water that has entered is frozen, the door body 28 can be pulled in a direction perpendicular to its surface. By doing so, the area around the door body 28 and the vent 22 is elastically deformed to remove ice adhesion. The door body 28 can be removed from the vent 22 without being affected by ice. Wear.

[0021] Next, on the inner surface of the side wall 20 of the container body 10, as shown in FIG. 1, FIG. 2, FIG. 3, and FIG. In addition, an engaging portion 42 is provided on the entire inner periphery except for the vent hole 22 portion. The engaging portion 42 is The inside of the container body 10 is divided into two stages, upper and lower, by the partition plate 15 that is engaged with the partition plate 15. It is integrally formed with the side wall 20 at a height of 100 mm. This engaging portion 42 As shown in FIGS. 5 and 6, the partition plate 15 is integrally molded from foamed resin. A step with a gentle slope on both longitudinal ends, i.e. on the short side. 44 is formed, and the central part forms a flat surface, and the fish placed on the partition plate 15 is 17 is molded so that its shape does not collapse. This partition plate 15 is used for heavy items such as mackerel, etc. A large fish 17 of It is formed with a predetermined strength. Note that the central part of the partition plate 15 in the longitudinal direction is lower than the upper surface of both ends and the wall thickness becomes thinner, so the bottom surface is lowered as shown in Figure 6. A thick portion 46 is integrally formed and reinforced. In addition, on the flat surface of the partition plate 15 groove 48 is formed, and when a large amount of liquid such as water enters, the liquid flows into the groove 4. It is designed to accumulate within 8. Note that the groove 48 substantially reduces the mechanical strength of the partition plate 15. The purpose is to reduce weight and cost by reducing the amount of material used without reducing It may be provided.

[0022] Further, the upper opening of the container body 10 is configured to be sealed with a lid 14. It is. That is, a linear convex portion 50 is provided at the upper end of the side wall 20 of the container body 10 for ventilation. A groove-shaped groove is provided at the lower end of the outer periphery of the lid body 14, except for the opening 22. A recessed portion 52 is provided around the circumference, and these linear convex portions 50 and groove-shaped recessed portions 52 The elastic force of the members causes a tight fit. Furthermore, in the vent 22 section, this The upper part of the door body 28 that is locked to the air port 22 is brought into contact with the bottom part of the lid body 14 that is covered. A convex portion 54 and a concave portion 56 are respectively provided so as to seal the vent 22. It is configured. Therefore, the container body 10 is sealed tightly by the lid body 14 and the door body 28. This improves the cold retention and airtightness of the foam container 12 for freezing and cold storage.

[0023] In the foam container 12 for freezing and cold storage having the above configuration, the bottom 1 inside the container body 10 In 6, put the items to be frozen (17), such as salted mackerel and other salted fish and fresh fish. After that, the partition plate 15 is inserted and engaged with the engaging part 42, and the cooled object is further placed on the partition plate 15. Put the frozen food (17) in, put the lid 14 on top of it, and tie the tie string to tie it all together. are tied together. Door body 28 from the vent 22 of the tied foam container 12 for freezing and cold storage is removed, and the opposing vent hole 22 is opened. Next, such a state The foam container 12 for freezing and cold storage is placed in the freezer, and cold air is smoothly released from the vent 22. The container body 10 is divided into upper and lower parts by a partition plate 15, and is stored therein. The frozen object (17) is quickly frozen. If the object to be frozen (17) is After the foam container 12 for freezing/cold storage is removed from the freezer, the vent hole is A door body 28 is locked to 22, and the vent 22 is sealed.

[0024] In this way, the upper opening of the container body 10 is sealed by the cover 14. The ventilation port 22 is kept cool and airtight by the door body 28, and the objects to be frozen inside are kept cool. (17) not only prevents so-called freezer burn, but also protects against fluctuations in outside temperature. It is almost unaffected by the heat and is kept cool at a nearly constant temperature. In addition, the partition plate 15 The partitioned foam container 12 for freezing and cold storage reduces the storage volume for frozen items (17). The height can be lowered without causing any problems, and a large amount of frozen objects (17) can be frozen overall. It becomes possible to Furthermore, the rigid partition plate 15 is attached to the engaging portion 42 of the side wall 20. Because they are engaged, the object to be frozen (17) placed on the partition plate 15 The object to be frozen (17) held by the partition plate 15 and placed thereunder is not subject to weight. Instead, the object to be frozen (17) is frozen in a deformed state or crushed. There is no need to worry. In addition, a partition plate 15 that partitions the inside of the container main body 10 is provided on the side. The strength of the wall 20 is increased, and the container body 10 is prevented from being damaged such as cracking.

[0025] The foam containers 12 for freezing and cold storage that have been delivered to markets etc. have their binding strings untied and their lids 14 After the container bodies 10 are taken and displayed for each container body 10, they are transported. At that time, the worker's If your arm or the like touches the door body 28, or if the container body 10 vibrates or undergoes complicated deformation. As a result, a force is applied to the door body 28 so as to push it up from the vent 22. Sometimes. Even in such a case, the engagement plate portion 38 of the door body 28 Since it is engaged with the engagement recess 40 provided in the side wall 20 of the main body 10, the door The body 28 does not float up from the vent 22. Further, the door body 28 has a locking protrusion 30 It is locked in the locking step part 24 and the groove-shaped recess 26 of the vent 22 by the linear convex part 32. Furthermore, the abutting plate portion 36 and the concave portion 34 are in contact with each other. Therefore, it is unlikely that the door body 28 will come off the vent 22 unless a considerable external force is applied. There's no way. Therefore, the vent 22 is opened while the container body 10 is being transported. This prevents the object to be frozen inside from slipping out of the vent 22. Change By tightly locking the door body 28 to the vent 22, the door body 28 is attached to the side wall 2. 0 and the reduction in strength of the side wall 20 caused by providing the ventilation hole 22. can be suppressed to a minimum.

[0026] Above, one embodiment of the foam container for freezing and cold storage according to the present invention has been described in detail. It is also possible to implement other forms.

[0027] For example, the partition plates used in the foam containers for freezing and cold storage according to the present invention come in various forms. As shown in FIG. 7, one side or each side of the partition plate 58 A notch 60 is provided in each, and the partition plate 58 is inserted by inserting a finger into the notch 60. It may be configured so that it can be pulled out from the container body 10. According to this example, the capacity In order to pull out the partition plate 58 from the container body 10, the door body is removed from the vent 22 of the container body 10. There is no need to remove 28.

[0028] The notch 60 provided in the partition plate 58 is the size of one finger, as shown in FIG. Alternatively, the notch 62 may be large enough to fit the palm of the hand. If the notch 62 is large In this case, the cold air flowing in from the vent 22 is not blocked by the ends of the partition plate 64 and is Cold air can smoothly flow into the upper and lower portions of the partition plate 64 from the notches 62. In addition, the partition plate While the object to be frozen (17) is placed on the container 64, it is removed from the container body 10 and transported. It is also possible to do so. Furthermore, as shown in the figure, a through hole is formed in the center of the partition plate 64. 66 may be provided so that cool air can be rapidly circulated through the through hole 66. . According to this example, the temperature of the frozen object stored in the sealed foam container for freezing and cold storage is The temperature can be kept almost constant between the top and bottom of the partition plate 64, and the temperature can be quickly and uniformly cooled. Can be frozen.

[0029] In addition, the shape of the partition plate must be dish-shaped as shown in the above example. For example, as shown in FIG. 9, the partition plate 68 has a plate body formed in a stepped shape. It may be divided into two or three parts. these The shape of the engaging portion 42 of the side wall 20 of the container body 10 is different for partition plates having various shapes. It is sufficient that the shape corresponds to the shape of the bottom of the partition plate. These partition plates 15, 58, 64, and 68 are molded from the same foamed resin as the constituent material of the container body 10. or different foamed resins, and even foamed resins and other materials. It may also be a laminated member made of materials, such as a structure made of hard resin or synthetic wood. It may be composed of.

[0030] In addition, as shown in FIGS. 10, 11, and 12, the partition plate 86 is made of foamed polystyrene. Extruded products can also be formed using the vacuum forming method of polystyrene paper. It is possible. The thickness of polystyrene paper is about 5 mm at most, so it cannot be used on a flat surface. With such a structure, it is not possible to place heavy objects such as fish on top of it. Therefore, As shown in the figure, a large number of grooves 88 are formed on the flat surface of the partition plate 86, and the grooves 88 are A reinforcing rib 90 is formed in a direction perpendicular to the groove 88, and the partition plate 86 has an uneven structure formed by the groove 88. The bending rigidity of the partition plate 86 and the compressive strength in the direction of the groove 88 are improved by the structure and reinforcing ribs 90. It is designed to increase the With this structure, you can use fish such as salted mackerel, etc. The partition plate 86 can receive a heavy load, and the partition plate 86 86 allows the side walls of the container body to be reinforced.

[0031] Next, the container body to which these partition plates 15, 58, 64, 68, 86 are engaged The engaging portion 42 formed on the side wall 20 of No. 10 is also not limited to the above-mentioned embodiment. Moreover, it is not necessary that the engaging portion 42 be formed around the entire circumference except for the vent hole 22 portion. Partition plate When placing items to be frozen on top of the partition plate, the partition plate may crack or the engaging part may be damaged. The engaging part is formed with a specified size and shape to prevent it from falling to the bottom of the container body. It is sufficient that a plurality of them be provided at key points on the side wall of the container body.

[0032] In addition, the foam container for freezing and cold storage according to the present invention is partitioned into two layers, upper and lower, inside the container body. For example, as shown in FIG. Engaging portions 74 and 76 are formed at two locations, and each of the engaging portions 74 and 76 has a size Different partition plates 78 and 80 are engaged to partition the inside of the container body 70 into three upper and lower stages. It may be configured as follows. In this example as well, the vent hole 8 is large formed in the side wall 72. By removing the door body 84 from 2, the items to be frozen stored inside can be quickly frozen. can be tied. In addition, in the above embodiment, for one container body It used to be constructed by covering one lid, but by stacking multiple container bodies, the lower container body can be covered. Seal the opening of the body with the bottom of the upper container body, and cover only the top container body with the lid. The present invention can also be applied to foam containers for freezing and cold storage configured as follows. , is not limited in any way.

[0033] Although the embodiments of the present invention have been described above in detail based on the drawings, the present invention is limited to the above-mentioned drawings. It is not determined. For example, the above embodiments apply to salted fish such as salted mackerel and raw fish. Although we have explained an example of storing fresh seafood in a foam container and freezing it, the freezing method according to the present invention - Foam containers for cold storage can also be applied to cold storage containers. Here, the cold storage The containers are used to maintain the freshness of fruits and vegetables when they are shipped to the market. A container that cools fruits and vegetables and maintains them at a low temperature. Stored in a cold container A method for cooling objects to be refrigerated, such as fruits and vegetables, involves bringing the objects into direct contact with cold air. or come into contact with cold air that is forcibly drawn in by creating a pressure difference inside and outside the container. It removes latent heat by evaporating moisture from the surface of the object to be refrigerated by exposing it to reduced pressure. There are other methods. In order to apply these cooling methods to the objects to be cooled, the cold storage container is equipped with ventilation. A vent is provided, and after cooling the object through the vent, airtightness and preservation are ensured. A door body is locked to the vent to maintain coolness.

[0034] Even in such a cold storage container, the capacity can be increased by partition plates as shown in the above-mentioned example. The inside of the container body is divided into multiple upper and lower stages, and multiple objects to be refrigerated stored inside the container body can be stored at the same time. The structure is such that the members cannot be directly stacked. In this example as well, the container body is It is also possible to provide a vent 22 and a door body 28 with a similar structure, but depending on the shape and size of the object to be cooled, The container body and partition plate are configured to suit the The vents and the gates that seal the vents are configured to comply with the law, and these shapes The shape and structure are not limited in any way.

[0035] In addition, the container body is molded using two or more types of foam beads with different expansion ratios. The corners that run from the side wall to the bottom of the container body, especially the corners where the tie strings are hung, are exposed. It is preferable that the foam bead is formed by foam beads having a low foam magnification to increase hardness. In addition, other parts of the container body are molded with foam beads with a high expansion ratio. Costs may also be reduced.

[0036] Furthermore, only the side wall of the container body is molded with foam beads with a low expansion ratio, making it possible to freeze and The strength of the foam container for cold storage may be increased. In addition to changing the foaming ratio, we also By changing the type of foam resin, for example, the side walls of the container body can be made of polystyrene and polyethylene. The bottom of the container body is made of copolymer resin foam, and other foams such as polystyrene are used to form the bottom of the container body. Depending on the body, it may be integrally molded using a known partial two-layer molding method. like this Polystyrene, which is highly flexible and difficult to break, but is easily deformed. and polyethylene copolymer resin foam, and although it is hard and difficult to deform, it is easily broken. Obtain high-strength foam containers for freezing and cold storage that have the characteristics of polystyrene foam. can be done. In addition, the combination and mixing ratio of foam resins should be determined based on the foam containers for freezing and cold storage. It can be set as appropriate by taking into account usage, cost, etc., and is limited to the above examples. It is not something that will be done.

[0037] In addition, the method of using the foam container for freezing and cold storage according to the present invention is optional. If necessary, place a water-absorbing sheet or the like on the bottom of the container body to prevent liquids from the frozen items. Settings can be made depending on the method of use, such as installing a cable. Also, ventilate the bottom of the container body. It is also possible to provide holes or drain holes. Furthermore, other known forms may be implemented. It is also possible to do so as appropriate.

[0038] Various embodiments of the present invention have been described above, and the foam container for freezing and cold storage according to the present invention It is also possible to configure the above embodiments by appropriately combining them. For example, the foamed resin material that makes up the container body, and the foamed resin material that makes up the door body, lid body, etc. Furthermore, the door body may be made of a material other than foamed resin. It is possible. In addition, ventilation holes formed in the side walls may be located in the center of the side walls, or Alternatively, it may be installed on the long side wall, and a lid is not necessarily required. The draft is subject to various improvements and modifications based on the knowledge of those skilled in the art without departing from its spirit. , it can be implemented in a modified form.

[Effect of the idea]

The container body of the foamed container for freezing and cold storage according to the present invention is made of a partition plate made of a rigid member. It is divided into upper and lower layers, and the partition plate is engaged with the side wall of the container body for support. Therefore, objects to be frozen or kept cool that are placed on the partition plate are placed on the partition plate. The objects to be frozen, which are supported and placed on the bottom of the container body, are placed on the partition plate. It will not be crushed by objects to be frozen. Moreover, the items to be frozen overlap each other. Since they are not mutually deformed, it is possible to maintain the quality of the frozen items, etc. . In addition, by arranging a partition plate made of a rigid member inside the container body, The strength of the container body is increased, and a foamed container that can withstand long-term use can be provided. Furthermore, the capacity Since the container is partitioned internally, individual foam containers can be stacked without changing the volume. The height of the foam container can be lower than that of stacking foam containers. Therefore, constant volume Store a large amount of foam containers for freezing and cold storage in the freezer, refrigerator, or truck bed. Can be loaded. Also, rather than stacking multiple single-tier individual containers, The production cost of the container is lower if the container body is partitioned into multiple parts using partition plates.

[0040] In addition, the side wall of the container body of such foamed containers for freezing and cold storage is closed by a door body. The material to be frozen inside the foam container for freezing and cold storage is Because it is configured to freeze or cool the object to be kept cold, the partition plate Objects to be frozen placed inside the partitioned container body are also quickly frozen or frozen. Objects to be kept cool can also be quickly precooled. After that, lock the door body to the vent and open the container. Keeps frozen or pre-cooled foam containers airtight by sealing the body. oxidation of objects to be frozen or cooled, sublimation (evaporation) of moisture from objects to be frozen, etc. It can prevent discoloration, etc. In addition, the door body closes the vent. By stopping the foam container, you can improve the cold retention properties of the foam container and protect items such as frozen items. Quality maintenance becomes easier.

[0041] In addition, the foam container for freezing and cold storage according to the present invention can be used with only the container body by removing the lid. Even when transported, the door body that is locked to the ventilation port is engaged by the engaging part, and the passage is prevented. Since the door is prevented from sliding along the edge of the air vent, the door body may lift up and fall off. There's nothing to do. Therefore, objects to be frozen or kept cool will slip through the open vents. There will be no accidents such as falling. Moreover, the engaging part engages the door body. By being closely integrated with the side wall and providing ventilation holes, The resulting decrease in side wall strength is minimized, resulting in stronger refrigeration and storage than before. A cooling foam container can be provided.

[0042] In this way, in the past, foam containers with high insulation properties, especially those sealed with lids, were used. It is not possible to store items to be frozen in a foam container and then freeze the items. However, according to the foam container for freezing and cold storage according to the present invention, it is possible to Not only can it be frozen, but also the ventilation holes provided opposite each other by the door body can be By closing it, you can ensure the original cold retention and maintain airtightness. This makes it easier to maintain the quality of frozen items. Furthermore, remove the door body from the vent. This makes it possible to re-cool the foam container for freezing and cold storage even if it is bundled with the lid etc. It can be frozen and can produce unprecedented effects.
