Description

  The present invention particularly relates to a heat insulating container suitable for refrigerated storage of fresh squid or transportation in a refrigerated state.

  In general, squid is stored in a refrigerated state or transported in a refrigerated state using a container made of styrene foam having high heat insulation, and is conveyed in a state of being filled with ice inside.

  By the way, even if the squid is fresh at first, if it is refrigerated or transported in direct contact with ice, the surface of the squid will turn white over time, and as a result, In some cases, it gives consumers the impression that freshness has dropped.

  Further, even when a part of the squid is immersed in water formed by melting ice in the container, there is a problem that the surface is whitened or the freshness is deteriorated from that part.

  Furthermore, if styrofoam boxes containing squid and the like are stacked in multiple stages, for example, water will drip from the upper container and the water will enter the lower container, resulting in freshness due to the water. There was also a risk of dropping.

  In view of such conventional problems, the present invention provides an insulated container that can be kept in a fresh state for a long time when, for example, squid is refrigerated or transported in a refrigerated state. It is intended to be.

  It is another object of the present invention to provide an insulated container capable of rapidly discharging water dripping downward from the upper stage to the outside of the container without infiltrating into the container when stacked in multiple stages.

The heat insulation container according to the present invention to achieve the above object,
A container body made of foam synthetic resin in which a bottom plate portion and four side wall portions raised from the bottom plate portion are integrally formed,
A lid made of a synthetic foam resin that is openably and closably attached to an upper end opening of the container body,
An inner container made of a synthetic resin sheet in which an article accommodating section is divided into a plurality of pieces so that the articles can be housed freely in and out of the container body and a plurality of articles can be individually accommodated. And
At the corner of the bottom plate portion in the container body, a drain hole is formed for taking out the water stored therein to the outside,
A drain hole is formed in each of the article storage sections formed in the middle container,
It is characterized in that the water stored in the middle container can be discharged to the outside from the drain hole through the drain hole of the container body.

According to the heat-insulating container having such a configuration, the articles housed inside are housed without directly touching the ice via the middle container. Therefore, for example, when squid is housed, the surface of the squid is translucent with good freshness. Can be stored or transported while maintaining a black state. Also, even if ice-melted water or the like accumulates in the middle container, the water can be quickly discharged out of the container body from the drain hole of the middle container through the drain hole of the container body.

  Here, in the present invention, in order to form a recess on the upper surface of the lid and guide the water remaining in the recess to the lower surface of the container body, the corner of the lid and the four corners are formed. It is preferable to form a drain passage penetrating between the corner and the side wall.

  If such a penetrated drainage passage is formed between the lid and the container body, the moisture that has fallen into the lid from above, for example, when stacked in multiple stages with the lid closed. Can be quickly discharged to the outside. Therefore, when performing the operation of opening the lid, or when performing the operation of lowering the containers one by one from the stacked container group, it is possible to prevent water from accidentally entering the container body. .

  In addition, it is preferable that a concave portion is formed as a water pool at both ends of the middle container, and the drain hole is formed in a bottom surface of the concave portion.

  If recesses are formed at both ends of the inner container and drain holes are formed in the recesses as described above, even if a small amount of water exists in the inner container, the water is collected and discharged to the outside. can do. Further, it is possible to prevent water from contacting the article as much as possible.

  Further, it is preferable that the drainage hole of the inner container is formed by a cut.

  With such a drain hole, it is possible to prevent water from entering from the opposite direction by the tongue piece of the cut. Therefore, the water once discharged or the melted ice water does not cling around the product.

  Further, it is preferable that the width of the article accommodating portion of the middle container is set to be substantially the same as the diameter of the body of the squid.

  Such a setting is suitable for storing and transporting squid.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an exploded perspective view of an insulated container according to one embodiment of the present invention, FIG. 2 is a cross-sectional view of the insulated container according to one embodiment of the present invention, and FIG. 3 is a plan view of the container body shown in FIG. .

  As shown in FIG. 1, the heat insulating container 2 of this embodiment includes a container body 4 made of a foamed synthetic resin, a lid 6 made of a foamed synthetic resin that is openably and closably attached to the container body 4, and a container body. 4 and a middle container 8 made of a molded article of a synthetic resin sheet.

  As shown in FIGS. 1 and 2, the upper end portions of the four side walls 3, 5, 7, 9 rising from the bottom plate 1 of the container body 4 project upward at the inner half of the wall thickness. An engaging groove 14 is formed on the lower surface of the lid 6 so that the engaging wall 12 fits into the engaging wall 12. By fitting the engagement wall 12 of the container body 4, the lid 6 is detachably attached to the upper end opening of the container body 4.

On the other hand, as shown in FIG. 3 and FIG. 4 which is a cross-section taken along the line CC of FIG. 3, water or the like stored inside is discharged to the outside at the corner of the bottom plate 1 in the container body 4. Drain hole 15 is formed. The drain hole 15 is formed radially from the corner in the container body 4 to the corner of the side wall, and the lower end opening thereof is inclined obliquely downward so as to promote drainage of water. It is formed.

  On the other hand, drainage passages 10 are formed vertically at the corners of the four side walls 3, 5, 7, 9 constituting the container body 4. The drain passage 10 passes through the gap between the side walls 3, 5, 7, and 9 and penetrates to the bottom surface of the container body 4. Then, as shown in FIG. 4, the drain hole 15 communicates in the middle.

  A substantially rectangular recess 20 is formed on the upper surface of the lid 6 made of a foamed synthetic resin, and a drain passage 18 is formed through a corner of the recess 20. The drain passage 18 is located on the same straight line as the drain passage 10 of the container body 4 described above. Therefore, even if water accumulates in the recess 20 of the lid 6, the water passes from the drainage passage 18 of the lid 6 through the drainage passage 10 of the container body 4 to the bottom side of the container body 4. Guided and discharged outside. Thereby, for example, even if the work of stacking up and down is performed and the water from the upper stage drops downward, the water does not enter the lower container body 4.

  Hereinafter, the structure of the middle container 8 housed in the container main body 4 so as to be freely taken in and out will be described. The inner container 8 is formed of a molded article of a synthetic resin sheet. As a whole, it is formed substantially in the shape of a dish, but the inner article storage portion is divided into a plurality of partitions 25 in an elongated semi-cylindrical shape, and in the divided space, for example, one article such as squid is provided. Each is accommodated. Further, the bottom surface of the article storage section M divided into a plurality of parts of the middle container 8 is rounded as shown in FIG. 7, so that squid and the like can be easily stored. Further, the width of the article storage section M is set to, for example, approximately the same size as the diameter of the body of the squid to be stored.

  As shown in FIG. 8, both ends of the article storage portion M of the middle container 8 are partially lower than the center portion, and a recess 30 is formed here as a water pool portion. Therefore, even if the water is dripped little by little into the article storage section M of the middle container 8 and the whole amount is small, the water is collected in the concave portions 30 at both ends which are lower by one step.

  Further, a U-shaped cut is formed on the bottom surface of the concave portion 30 by, for example, a cutter blade as shown in FIG. 7, and the cut forms a drain hole 31. Therefore, the water accumulated in the concave portion 30 of the inner container 8 can be discharged to the outside through the drain hole 31 regardless of the amount.

  The drain hole 31 is an extremely narrow slit-shaped opening, and water flows downward through the drain hole 31. The cut tongue piece is formed by the flow of the water. While flowing, it has a posture folded down. Therefore, the tongue formed by the cut can effectively prevent water from entering in the opposite direction as if it were a valve.

  The configuration of the heat insulating container 2 according to one embodiment of the present invention has been described above, and the operation thereof will be described below.

  The heat insulating container 2 of the present embodiment can be preferably used for transporting fresh products such as squid and fish. In this embodiment, particularly, a case where fresh squid is transported by refrigeration will be described.

  First, an appropriate amount of ice is put into the container main body 4 and laid out on an average, and the middle container 8 is placed thereon. Then, for example, fresh squid is laid inside the inner container 8. At this time, it is preferable that the width of the article storage section M is set substantially equal to the diameter of the body of the squid. Further, it is preferable that the length of the article storage portion M is a length that can store the entire length of the body of the squid.

  When a predetermined number of squids are stored, the lid 6 is mounted on the container body 4. As a result, the squid is indirectly cooled without directly touching the ice.

  In the container body 4 according to the present embodiment, the squid and the ice do not come into direct contact with each other, so that even if the squid is stored or transported as it is, the freshness can be maintained for a long time. That is, white discoloration of the surface of the squid can be prevented. Also, even if water comes out of the squid itself or a part of the ice melts with the passage of time and ice water comes out onto the inner container 8, the inner container 8 has drain holes 31 at both ends. Is formed, the water in the middle container 8 can be discharged into the container body 4 through the drain hole 31 regardless of the amount. Further, since the drain hole 15 is formed in the container body 4, the water discharged from the drain hole 31 can be discharged to the outside of the container body 4 through the drain hole 15. Therefore, even if water exists in the middle container 8, the water can be discharged to the outside of the container body 4.

  Further, even if the cooling ice is not melted in the container main body 4, the water formed in the container main body 4 can be quickly discharged to the outside through the drain holes 15, not in the inner container 8. Thereby, water does not accumulate in the inner container 8 or the container main body 4. Therefore, the squid does not come into direct contact with ice or water, and thereby, it is possible to prevent the surface of the squid, which looks bad in freshness, from whitening.

  In this way, fresh squid can be kept translucent and fresh in color over a long period of time. Thus, from the standpoint of a wholesaler, fresh squid can be wholesaled to the next trader, so that an extremely effective insulated container can be provided in the logistics field.

  In addition, consumers far away from the production area can eat fresh squid.

  On the other hand, a case where the lid 6 is put on the container main body 4 and stacked in multiple stages in this state will be described. In this case, water may drop from the upper container body 4 toward the lower lid 6, but in this case, water from above is discharged from the drain passage 18 of the lid 6 to the container body 4. It can hang straight down through the drain passage 10 and discharge to the outside of the container. Therefore, it does not stay near the opening of the container.

  As described above, in this embodiment, not only the water with the melted ice does not stay in the container body 4, nor does the water or the like dropped from above enter the container body 4. Therefore, for example, when squid with good freshness is stored, contact between squid and ice or squid and water can be reduced as much as possible, and only cooling can be promoted.

  As mentioned above, although the heat insulation container by one Example of this invention was demonstrated, this invention is not limited to the said Example at all. For example, in the above-described embodiment, the case where squid is accommodated has been described. However, for example, it is also suitable for refrigerated storage or transport of a slender fish such as cabbage. Further, the present invention is not limited to fresh fish, and can be used as a container for storing meat and the like in a refrigerator or for taking ice cream home.

  In such a case, the shape or width of the article storage portion M of the middle container 8 may be appropriately changed according to the shape of the article.

  Further, the inner container 8 can be used as it is as a display tray.

In the above embodiment, the drainage hole 31 formed in the inner container 8 is formed by cutting with a cutter or the like. However, a small round hole or the like may be formed instead.

  However, it is preferable to simply cut the drain hole 31 rather than the round hole in that the intrusion of water from the opposite direction can be prevented.

  Further, in the above embodiment, although not particularly mentioned, a low groove-shaped step may be formed in the bottom plate 1 of the container body 4. If such a low groove-shaped step is formed, a portion having a low step can be used as a path for water, and the width of the passage of water is reduced, so that the discharge of water can be promoted. Therefore, it is possible to prevent a small amount of water from staying on the lower surface of the bottom plate portion 1 of the container body 4 and quickly drain unnecessary water from the drain hole 15.

  In the above embodiment, only one middle container 8 is accommodated in the container body 4. However, if the height of the container body 4 is increased, the middle container 8 can be provided in two, three or more stages. , Can also be accommodated.

  Further, in the above embodiment, ice is exemplified for cooling. However, depending on circumstances, a cooling medium such as a cooling agent may be used. The ice can be used either in a crushed state or in a large lump such as a block as it is, as long as the medium container 8 can be stably placed.

  If the size of the recess 20 of the lid 6 is set to a size that can fit the bottom projection of the container body 4, the bottom surface of the container body 4 can be stably placed on the lid 6. Can be fitted. Thereby, collapse of the load of many stacked heat insulating containers 2 can be prevented.

  As described above, the heat-insulating container 2 of the present invention can be in various modes, and is not limited to the above-described embodiment. In short, the inner container 8 is provided inside so that the article does not come into direct contact with ice or the like. The drainage holes for draining water may be provided in the inner container 8 and the container body 4, and water may be discharged from these drainage holes. In addition, dust can be discharged to the outside by the drain hole. However, if the size of the drain hole is too large, warm air may enter from the outside and the cooling effect may be impaired. The size of the drain hole may be set according to the size.
