Description

  The present invention relates to a frozen shrimp wrapping body in which a block of ice blocks in which a plurality of shrimps are confined in a frozen state is stored in a packaging box.

  Shrimp generally have a characteristic that meat tissue tends to collapse due to weak connective tissue. In particular, the neck of shrimp is easily damaged, and even a slight damage can lose freshness. In addition, when the surface of shrimp is dried by sublimation of water, lipid oxidation and the color change associated therewith are promoted, so that the freshness rapidly decreases even when the surface is dried. Therefore, conventionally, when the shrimp is stored frozen, a water injection block freezing method is generally employed to prevent damage and dryness.

  In this water injection block freezing method, a large number of raw shrimp of about 1.8 kg is stored in a box-shaped block formation container in a state of being stacked in multiple stages, poured into water, and then frozen to prepare a frozen shrimp block. Even if it is stored in a refrigerator for a long time, it is difficult to dry and can be stored for a long time. Even if the frozen shrimp block is not broken even if it receives a slight impact during distribution (delivery) of the product, the shrimp in it will not be damaged. In addition, since the surface of the frozen shrimp block is covered with ice, even if it is exposed to high temperature outside air for a short time, the surface ice melts somewhat, but the shrimp inside is well protected.

  However, in the water injection block freezing method described above, it takes a long time for thawing, and the amount of shrimp contained in this frozen shrimp block is about 50, so retailers and general consumers purchase it as it is and thaw it. Even if you can't use all the shrimp at once. In addition, if the material that has been thawed once is re-frozen, the quality is significantly degraded and the commercial value is greatly reduced.

Therefore, in order to solve such a problem, a frozen shrimp package in which the frozen shrimp block in which shrimp is confined is divided into a plurality of flat thin ice blocks in the direction in which the shrimp is stacked has been proposed (for example, (See Patent Document 1).
There has also been proposed a frozen shrimp package in which a plurality of shrimps are sealed one by one in a transparent pack or the like and frozen, stored, or the like (see, for example, Patent Document 2).

Utility Model Registration No. 3102898 JP 2000-245401 A

  In what was described in patent document 1, since it can defrost for every several thin-walled ice block, the time required for defrosting can be shortened significantly rather than defrosting the conventional thick frozen shrimp block. However, since the thin ice block is formed by dividing one thick frozen shrimp block in the direction in which the shrimp is stacked, it is difficult to manufacture and one thin ice block is quite Handling is inconvenient because it is large.

  Moreover, in what was described in patent document 2, since a plurality of shrimps were irregularly packed in a transparent pack, they were frozen when the product was delivered or when the frozen shrimps were taken out from the transparent pack. When the frozen shrimps in contact with each other, important parts of the shrimp such as the tails of the shrimp are removed or damaged, so that the appearance of the shrimp deteriorates and the commercial value of the frozen shrimp is significantly reduced. .

  This device has been made by paying attention to the above-mentioned problems, and can easily store and take out a required amount of shrimp in a frozen state, and can prevent loss of the tail of the shrimp. The object is to provide a frozen shrimp package.

  The frozen shrimp package according to the present invention comprises a plurality of ice block blocks in which a plurality of shrimps are confined in a frozen state, and are stored in a packaging box side by side. Shrimp are stacked in multiple stages with their tails facing inward.

According to the frozen shrimp package according to this device, the shrimp is stored frozen in each ice block, so that only the number of shrimp as needed can be thawed by thawing each ice block. In addition, the time required to thaw one ice block is extremely less than the time required to thaw a conventional frozen shrimp block.
Further, since each shrimp is confined in the ice block with its tail directed inward, the shrimp tail is not damaged, and the shrimp tail can be prevented from being lost.

  In addition, by appropriately changing the number of shrimp tails accommodated in each ice block, it is possible to store frozen shrimp in the number corresponding to the usage amount of the user such as a restaurant, a retailer, or a general consumer in each ice block.

In a preferred embodiment of the present invention, each ice block is housed in a packaging box in a state of being housed and packaged in an inner bag. Here, various types of “inner bags” such as plastic bags and paper packaging bags can be considered.
According to this embodiment, since each ice block is stored in the packaging box in a completely separated state, it can be taken out in units of ice blocks and is easy to handle.

In a preferred embodiment of the present invention, each of the ice block is formed in a convex curved surface in which the corners of the four corners draw a smooth curve.
According to this embodiment, the corner of the ice block can be prevented from being lost, so the surface of the shrimp is not exposed.

  According to this device, shrimp can be thawed in a quantity necessary for use, and defects such as the tail of frozen shrimp can be prevented.

FIG. 1 shows the structure of a frozen shrimp package 1 according to an embodiment of the present invention. This frozen shrimp package 1 is composed of a plurality (eight in this embodiment) of ice block 7 in which a plurality of shrimps 3 are confined in a frozen state, and a packaging box 10 for storing the ice block 7. . Each ice block 7 is housed in a plastic bag 11 and packaged, and each ice block 7 is housed in a packaging box 10 in a side-by-side state. Note that all the ice block 7 may be accommodated in one plastic bag 11 and stored in the packaging box 10.
In the figure, reference numeral 12 denotes an openable / closable lid provided on the packaging box 10 containing the ice block 7.

As shown in FIG. 2, the ice block 7 has a rectangular parallelepiped shape close to a cube, and the shrimp 3 having a predetermined number of fish (six fishes in this embodiment) is present in the ice block 7 and the tail portion 30 faces inward. So that it is trapped.
Further, the corners of the four corners of the ice block 7 are formed on the convex curved surface 5 that draws a smooth curve.

Since each shrimp 3 is frozen in the ice block 7 with its tail 30 facing inward as described above, the tail 30 of the shrimp 3 is transferred to another ice block 7 or the packaging box 10 during transportation or the like. The tail of the shrimp 3 can be prevented from being damaged, and the shape of the shrimp 3 can be held.
By immersing each ice block 7 in flowing water and thawing, a predetermined number (6 in this embodiment) of shrimp 3 is thawed as necessary.

  As shown in FIG. 3, the ice block 7 is manufactured by using a tray 2 whose inside is partitioned and formed in parallel by a partition plate 4. After storing a predetermined number of fish, a predetermined amount of water is poured into the tray 2 and left in this state in a low temperature atmosphere of −20 ° C., thereby obtaining ice blocks 7 corresponding to the number of shrimp storage chambers 6. Hereinafter, the production method of the ice block 7 will be described in more detail.

The tray 2 is a box-shaped container in which four side wall portions 21 are integrally provided on the periphery of a flat rectangular bottom portion 20, and the upper surface thereof is open, and the partition plate 4 and shrimp are opened from the opening portion 22. 3 can be taken in and out.
As a material used for the tray 2, paper, processed paper, resin materials such as silicon and plastic, and metal materials such as aluminum and stainless steel can be used.

On the bottom portion 20 of the tray 2, a partition plate 4 that partitions the inside of the tray 2 into a plurality of regions is provided. The middle partition plate 4 is formed by integrating a single partition wall 40 that partitions the tray 2 in the horizontal direction and a plurality of partition walls 41 that partition the tray 2 in the vertical direction. It is divided into a plurality of rectangular regions.
As the material used for the partition plate 4, it is preferable to use a metal material such as aluminum or stainless steel or a resin material such as plastic or silicon having flexibility and elasticity even in a low temperature state.

  The partition plate 4 is removable from the tray 2, and when the partition plate 4 is inserted into the tray 2, the inside of the tray 2 is divided into a plurality of parts by the vertical and horizontal partition walls 40 and 41 and the side wall 21 of the tray 2. The shrimp storage room 6 is partitioned and a predetermined number of shrimp 3 can be stored in each shrimp storage room 6. In addition, although the number of shrimp storage rooms 6 is eight in the illustrated example, it can be increased to 9 or more, or can be decreased to 7 or less.

  Concave members 9 having concave curved surfaces 8 are arranged at the four corners of each shrimp storage chamber 6 so that the four corners of the manufactured ice block 7 become convex curved surfaces 5 that draw a smooth curve. As will be described later, when a predetermined amount of water is poured into the tray 2 and left in a low temperature atmosphere, the water becomes an ice block 7 in a state of being in close contact with the partition plate 4. For this reason, when the ice block 7 is separated from the partition plate 4, if the corners of the ice block 7 are squared, it is difficult to separate the ice block 7 from the partition plate 4. There is a possibility that the corner portion of the block 7 is lost and the surface of the shrimp 3 is exposed. In this embodiment, it is easy to separate the ice block 7 from the partition plate 4 by forming concave curved surfaces 8 at the four corners of each shrimp storage chamber 6, and the four corners of the ice block 7 are thereby formed. A convex curved surface 5 that draws a smooth curve is formed.

In this embodiment, as shown in FIG. 4, the corners of the four corners of each shrimp storage chamber 6 are formed as concave curved surfaces 8 by fitting concave members 9 whose surfaces are concave curved surfaces 8 into the four corners of each shrimp storage chamber 6. . As a material used for the concave member 9, a metal material such as aluminum or stainless steel can be used, but it is desirable to use a resin material such as plastic or silicon having flexibility and elasticity even in a low temperature state.
The concave curved surface 8 is not limited to the method of this embodiment, and is formed by applying putty to the four corners of each shrimp storage chamber 6 or by spot welding a bent metal plate or the like. May be. Alternatively, each corner of the partition plate 4 and four corners of the tray 2 may be formed by sheet metal processing.

  As shown in FIGS. 3 and 5, the shrimp 3 is accommodated in each shrimp storage chamber 6 having the above-described configuration so that the tail portion 30 faces inward. In this embodiment, first, after removing the head and selecting sizes of large, medium, and small, as shown in FIG. Are arranged on the tray 2 so as to face inward and face each other. Next, on the shrimp arrangement layer, as shown in FIG. 5 (2), with the two shrimps 3 curled, the tail portions 30 face inward and face each other so that the lower shrimp 3. Change the direction and change the direction. Finally, on the second shrimp array layer, as shown in FIG. 5 (3), with the two shrimps 3 curled, the tail portions 30 face inward and face each other. Change the direction of the shrimp 3 and change the direction.

  In this embodiment, each shrimp storage room 6 contains six shrimp 3 and is stored frozen. However, the present invention is not limited to this, and the usage amount of purchase target persons such as restaurants, retailers, general consumers, etc. It is also possible to increase the number of shrimp 3 to be accommodated to 7 or more or to reduce it to 5 or less. At this time, each shrimp storage chamber 6 is formed by appropriately changing the interval between the partition walls 41 of the middle partition plate 4 according to the number of shrimp 3 accommodated.

  Next, when a predetermined amount of water is poured into each shrimp storage chamber 6 and allowed to stand in a low temperature atmosphere of −20 ° C., the water freezes in a state of being in close contact with the partition plate 4 in each shrimp storage chamber 6 and shrimp. 3 is confined in each ice block 7.

  Finally, as shown in FIG. 6, the eight ice blocks 7 are extracted from the tray 2 in a state of being integrated by the partition plate 4. When an external force is applied to the partition plate 4 in this state, for example, when the partition plate 4 is bent and deformed, the partition walls 41 of the partition plate 4 are deformed in a direction in which they are spaced apart from each other, thereby closely contacting the partition plate 4. Each supported ice block 7 is separated from the partition plate 4 to obtain an ice block 7.

  The ice block 7 is packed in a plastic bag 11 and the packed ice blocks 7 are stored side by side in the packaging box 10 to form the frozen shrimp package 1.

In the above-described embodiment, when the partition plate 4 is pulled out from the tray 2 after the ice block 7 is frozen, each ice block 7 is surely attached to the partition plate 4 and is lifted up easily from the tray 2. It is desirable to be separated. For this purpose, the partition plate 4 may be easily extracted from the tray 2 by applying oil or the like to the inner surface of the tray 2.
Further, when the ice block 7 is separated from the intermediate partition plate 4 after freezing by applying oil or the like to the surfaces of the partition walls 40 and 41 of the intermediate partition plate 4 before freezing of the ice block 7, Each ice block may be easily separated from the partition plate 4.

According to the frozen shrimp packaging container 1 having the above-described configuration, the shrimp 3 is frozen in a state of being divided into each ice block 7, so that the number of shrimp 3 can be thawed as needed, and the ice block The time required to thaw 7 is significantly less than the time required to thaw the conventional frozen shrimp block, and the required amount of running water is reduced accordingly.
Furthermore, since each shrimp 3 is confined in the ice block 7 with the tail 30 facing inward, the tail 30 of the shrimp 3 is not damaged, and the loss of the tail 30 of the shrimp 3 can be prevented.
