Description

[Detailed description of the invention] (Industrial application field) This invention is a method for storing frozen foods, such as fresh foods and ice packs for cooling these foods, in a freezer with a simple structure and in a short time. The present invention relates to a storage device for freezing materials to be frozen.

(Prior art) When transporting perishable foods to long distances, in order to maintain the freshness of these foods, a pre-frozen refrigerant is placed together with them in special cardboard or Styrofoam boxes and loaded. It is transported to the destination.

The above-mentioned cold pack is frozen in a freezer. In this case, if the ice packs are in small quantities, they are usually taken out of the cardboard box, etc., placed on a separate shelf, etc., and frozen; however, if the ice pack is in large quantities, they are frozen while being stored in the cardboard box, etc. This has traditionally been done.

(Problems to be solved by the invention) By the way, when freezing these while stored in a cardboard box etc. as in the conventional configuration described above,
Since the ice packs are stacked one on top of the other and bonded to each other, the surface area of the ice pack that comes into direct contact with the cold air is reduced, which inconveniences that it takes a long time to freeze the ice pack.

(Purpose of the invention) This invention was made with attention to the above-mentioned circumstances, and it is a simple structure to freeze the frozen materials when they are stacked in a case. The aim is to be able to do this in a short amount of time.

(Structure of the invention) The feature of this invention to achieve the above object is that the raw material for the shelf board is a flat board made of cardboard, and the horizontal middle part of this flat board is bent into a vertical V-shape. A partition protrusion is formed to horizontally partition a flat plate material, and a locking piece is formed by cutting and raising a part of one of the opposing pieces forming the partition protrusion. One piece is fitted into a locking hole formed in the other opposing piece to lock it, and a partition piece is provided that partitions each flat plate material partitioned by the partition protrusion at a midway point in the direction in which the partition protrusion extends. A part of this flat plate material is cut and raised, and the material to be frozen can be accommodated on the flat plate material partitioned by the partition protrusions and the partition pieces.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

In FIG. 1, 1 is a cardboard case, and this case 1 has a cylindrical body 2 that is rectangular in plan view.
A lid plate 3 is rotatably integrally formed on the upper and lower edges of the body 2. In the example shown by solid lines, the upper and lower openings of the body 2 are both closed by the lid plate 3. From this state, if each cover plate 3 on the upper edge of the body 2 is rotated upward as shown by the two-dot chain line in the figure, the upper opening of the body 2 is opened. . In addition, the body 2 has this body 2.
A pair of grip holes 4 are formed by cutting and raising a portion of the case 1 toward the inside of the case 1. 5 is the cut piece.

A plurality of shelf boards 7 on which ice packs 6, which are an example of materials to be frozen, are placed are housed in the case 1 in a vertically stacked manner. The ice pack 6 is then frozen together with the case 1 in a freezer (not shown). In this case, case 1 containing ice pack 6
Handling such as conveyance is performed by the operator inserting the tip of his hand into the gripping hole 4 and gripping the upper edge of the gripping hole 4.

The configuration of the shelf board 7 will be explained in more detail with reference to FIGS. 2 to 6.

The raw material for the above shelf board 7 is a flat board material 9 made of cardboard.
, two places in the middle of the horizontal direction of this flat plate material 9 are bent into a vertical V-shape to form the partition protrusion 1.
0 and 10 are formed. In addition, the same flat plate material 9
Both horizontal ends of the folded piece 1 are also bent upward.
1 is formed. These partition protrusions 10 and bent pieces 11 are parallel to each other and partition the flat plate 9 into three sections at approximately equal intervals in the horizontal direction, so that three grooves 15 are formed on the flat plate 9. There is.

Further, the opposing pieces 1 forming each of the partition protrusions 10 are
A locking piece 16 is formed by cutting and raising one opposing piece 12 of the locking pieces 2 and 13, and the width of the protruding end of this locking piece 16 is larger than that of its base. Further, in correspondence with this locking piece 16, a locking hole 17 is formed in the other opposing piece 13, into which this locking piece 16 is removably inserted. By fitting and locking,
The shape of the partition protrusion 10 is maintained and reinforced. In this case, the first cut hole 18 formed by cutting and bending the locking piece 16 and the locking hole 17 communicate with each other to enable ventilation between the adjacent grooves 15, 15. Note that when the locking piece 16 is locked in the locking hole 17, the opposing surfaces of both opposing pieces 12 and 13 may be joined together as a whole.

Further, a partition piece 19 that partitions each of the grooves 15 at a midway point in the longitudinal direction is formed by cutting and bending a part of the bottom plate of the groove 15. The ice pack 6 can be accommodated on the flat plate 9 partitioned by the partition protrusion 10, the bent piece 11, and the partition piece 19.

The second cut-and-raised hole 20 formed by cutting and raising the partition piece 19 allows the upper and lower sides of the flat plate 9 to communicate with each other, and thus allows ventilation between the upper and lower sides of the flat plate 9. Furthermore, since the second cut holes 20 are located on the end side of each cold pack 6, they are prevented from being blocked by the cold packs 6, thereby ensuring the above-mentioned ventilation. Further, a semicircular notch 21 is formed at the end of each groove 15, and this notch 21 functions similarly to the second notched hole 20.

Each shelf board 7 formed from the flat plate material 9 as described above is stacked inside the case 1. At this time, the upper ends of the partition protrusion 10, the bent piece 11, and the partition piece 19 contact and support the lower surface of the shelf board 7 located above, and at this time, the A ventilation gap 22 is formed between the upper surface of the agent 6 and the lower surface of the shelf board 7 above this. In this case, the upper end of the partition protrusion 10 of the shelf board 7 located below tries to fit into the partition protrusion 10 of the shelf board 7 located above it, but the partition of the shelf board 7 located below The upper end of the protrusion 10 comes into contact with the locking piece 16 of the shelf board 7 located above, thereby preventing the partition protrusion 10 from fitting into each other. Therefore, the gap 22 is maintained at a predetermined size.

Then, when the shelf boards 7 on which the ice packs 6 are placed are stacked inside the case 1 as described above, and the ice packs 6 are stored in the freezer together with the case 1, the ice packs 6 inside the case 1 are stacked due to heat transfer. Frozen. Furthermore, the cold air that has entered the case 1 through the gripping holes 4 passes through the notches 21, the second notched holes 20, and the first notched holes 18, and comes into direct contact with the surface of the ice pack 6, thereby freezing it.

In the above case, the case 1 and the shelf board 7 are square in plan view, and the partition protrusion 1 of the upper and lower shelf boards 7 is
If these shelf boards 7 are stacked so that the 0 and bent pieces 11 are perpendicular to each other in plan view, the above-mentioned upper and lower partition protrusions 10 and 10 can be more reliably prevented from fitting into each other, and a gap of a predetermined size can be prevented. 22 can be obtained more reliably.

In FIG. 7, the figure shows a flat plate just before it is assembled into a shelf board 7, and cuts for the locking pieces 16 and partition pieces 19 have been made in the flat plate 9, and the locking holes 17 and A punch is made for the notch 21.

(Effects of the invention) According to this invention, the materials to be frozen on the shelves are stored in the compartments formed by the partition ridges and partition pieces, and are housed in the case in an orderly arrangement. The materials to be frozen are evenly frozen with respect to each other. Therefore, the freezing time of the entire frozen material can be shortened by the amount that each frozen material is not unevenly frozen. In addition, since the partition ridges and partition pieces of the shelf board support other shelves located above this shelf board, a predetermined gap is created between the top surface of the material to be frozen and the shelf board above this. It can be secured. Therefore, since a large surface area of the material to be frozen that comes into direct contact with the cold air can be ensured, the freezing time of the material to be frozen can also be shortened in this respect.

Moreover, by forming locking pieces and locking holes to maintain and reinforce the shape of the partition protrusion, the spaces partitioned by the partition protrusion communicate with each other, and furthermore, by forming the partition protrusion, the shelf The spaces above and below the board will also communicate with each other. Therefore, the cool air can smoothly circulate around each material to be frozen, further promoting uniform and effective freezing of each material to be frozen.

In addition, the above shelf board can be made by simply bending a flat plate material,
Since it is formed by cutting and bending, the structure is simple and useful for forming shelf boards. Moreover, since the items immediately before being assembled into shelf boards can be made into a flat plate, this is useful in terms of transportation and other handling.
