Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container for packaging frozen fish, especially a packaging container for storing frozen shrimp.

[0002]

[Prior art]

 Today, most of the shrimp are frozen and imported to Japan from Indonesia, Australia, etc. depending on the conditions of their fishing grounds, etc., and most of them are stored and sold. By the way, when importing such frozen shrimp, commercial transactions are carried out using a “frozen shrimp ice-stuffed block” as one unit, which is formed by filling approximately 2 kg of shrimp in an appropriate number of squares. There is.

However, even one unit of the frozen shrimp ice-stuffed block, the quantity of shrimp contained in this block is too large and expensive as one consumption in normal life. Therefore, secondary wholesalers, retailers, and their consumers cannot purchase and thaw this frozen shrimp ice-stuffed block at the same time and sell it, cook it, etc. It is often difficult to dispose of, resulting in a waste of the purchase.

On the other hand, in order to avoid such inconvenience, a shrimp wholesaler in Japan thaws the above-mentioned chilled and frozen shrimp ice-stuffed blocks and selects them into large, medium and small shrimp sizes, and the shrimp simple substance is subjected to ultra-low temperature It is re-frozen by freezing and then stored and stored in small quantities in dish trays, transparent vinyl, etc. as appropriate.

However, the frozen shrimp thus subdivided into individual units are packed in parallel with each other in a stacked state using a tray tray, or are not packed as a bag of transparent vinyl or the like. Since they are stored according to regulations, when the packed shrimp are packed or when the frozen shrimp alone is taken out from the pack, these frozen frozen shrimps come into contact with each other. , The tail and other important parts of the shrimp's appearance were missing and looked bad, and it became impossible to use it for events such as congratulations, thus reducing the commercial value of frozen shrimp.

[0006] Furthermore, at the stage of packing and bagging the frozen prawns in this dish-shaped tray, and at the stage of storing the frozen prawns in an open-type display case for cold storage for sale, the outside temperature and products are packed or selected. Since the contact with the purchaser's hand (body temperature) is inevitable, the thin ice protective film coated on the surface of the shrimp is thawed, and the whole shrimp in the tray is connected by subsequent refreezing. There were also drawbacks such as freezing and difficulty in separation.

[0007]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned circumstances, and the problem to be solved is to eliminate the inconvenience of selling and consuming frozen shrimp in units of ice-filled blocks, and to provide the necessary amount of shrimp for sales and processing. It can be easily stored and taken out as a single unit in a frozen state, and it prevents the loss of the eyes, whiskers, tails, etc. of headed frozen prawns and maintains the original appearance of prawns. It is an object of the present invention to provide a frozen shrimp packaging container having a simple structure that can effectively prevent the reduction of the amount of water.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the invention according to claim 1 will be described with reference to the drawings, and is used for storing, freezing, preserving, transporting, etc. of spiny lobsters, car prawns and other prawns. In a box-shaped packaging container with an open upper surface, the partition wall 2 is connected to the bottom of the inner surface of the box-shaped packaging container in a single row or in multiple rows, and the height H of the partition wall 2 is stored. Frozen shrimp packaging container 1 characterized in that the frozen shrimp 4 can be freely stored and taken out individually as a part h or more related to the maximum value of the head lateral width or the body lateral width W of the shrimp in 1 above. Is the content of the means.

According to a second aspect of the invention, the partition wall 2 according to the first aspect is housed in a space dimension X between the partition walls 2 and between the partition wall 2 and the side wall 20 of the box-shaped packaging container. The shrimp 4 is arranged in parallel so that it is wider than the tail lateral width Y of the shrimp 4 and narrower than the head or the same lateral width W maximum value, and the partition wall 2 is formed into the shape of the frozen shrimp 4 to be stored. The contents of the means are that the frozen shrimp 4 can be freely stored and taken out so that the frozen shrimp 4 can be freely received and taken out.

According to a third aspect of the present invention, the partition wall 2 of the frozen shrimp packaging container 1 according to the first aspect includes the partition walls 2 and the partition wall 2 and the partition wall 2 and the side wall 20 of the box-shaped packaging container. The contents of the means are that they are arranged in a slanted shape, a substantially zigzag shape, or a fan shape so as not to be parallel to each other, and that the frozen and frozen shrimp 4 can be freely stored and taken out individually.

According to a fourth aspect of the present invention, the partition wall 2 of the frozen shrimp packaging container 1 according to claim 1, 2 or 3 and, if necessary, the box-shaped packaging container peripheral side wall 20 has a top portion thereof. The content of the means is that the cutout recesses 5 are provided at appropriate intervals downward from.

[0012]

[Action]

 The operation of the device according to claim 1 will be described together with its use mode. In the container 1 for packaging cold-frozen shrimp according to the present invention, a partition wall 2 forms a storage chamber 3 for storing frozen shrimp 4 individually. To do. In the storage compartment 3, the frozen shrimp blocks that have been thawed after the above-mentioned frozen shrimp block are rapidly frozen are separately stored and wrapped in wraps.

In this case, the frozen shrimp 4 are stably placed and stored by the partition wall 2.

Further, since the height H of the partition wall 2 is equal to or greater than the portion h related to the maximum value of the head lateral width or the body lateral width W of the stored frozen prawns 4, the frozen prawns 4 are stably mounted. The frozen shrimps 4 are completely disconnected from each other. Therefore, the required quantity of frozen prawns 4 can be packed and taken out without touching other frozen prawns 4, and small-lot sales and small-lot cooking are possible.

Furthermore, during packing work of the headed frozen shrimp 4, during storage, transportation, removal, etc., there is no collision between the frozen shrimps 4, and when these are frozen continuously or in a semi-frozen state. Since it is not necessary to perform unreasonable separation, defects such as eyes, whiskers and tails of the frozen shrimp 4 are prevented, and the original shape of the headed shrimp 4 can be maintained.

In addition, even if a part of the frozen shrimp 4 in the container is thawed during storage and transportation, the presence of the partition wall 2 does not induce the thawing of the other frozen shrimp 4, and Even if this is refrozen again, the situation of continuous freezing of the frozen prawns 4 does not occur.

Next, in the invention of claim 2, the interval dimension X between the partition walls 2 including the side wall 20 of the box-like packaging container is wider than the tail lateral width Y of the shrimp 4 to be stored. Further, it is formed to be narrower than the maximum value of the head portion or the lateral width W of the head portion. Therefore, when the frozen shrimp 4a is stored therein, the frozen shrimp 4a first comes into contact with the partition wall 2 of the storage chamber 3a in FIG.

However, since the partition wall 2 is flexible or swingable, when the frozen shrimp 4a is further pushed, the partition wall 2 is deformed, and as shown in FIG. 4, the partition wall 2 finally becomes the frozen shrimp. 4a bulges outward along the body shape of the frozen shrimp 4a at the portion in contact with the head or the body portion 30 of 4a. On the other hand, the distance X between the partition walls 2 is wider than the lateral width Y of the tail portion of the frozen shrimp 4a stored in a frozen state. Therefore, in the vicinity of the tail portion 40 of the stored frozen shrimp 4a, the interval dimension X between the partition walls 2 does not greatly change.

Next, another frozen shrimp 4b is pushed into the shrimp storage small chamber 3b adjacent to the above storage small chamber 3a with the head and tail of the frozen shrimp 4a already stored in the opposite direction. 2 is deformed, and finally the partition wall 2 bulges outward along the body shape of the frozen shrimp 4b at the portion contacting the head or body portion 30 of the frozen shrimp 4b.

In this case, since the head or body 30 or both tails 40 of the newly-stored frozen shrimp 4b are accommodated in the tail of the already-stored frozen shrimp 4a, the partition wall 2 is transformed into a twisted state, and the frozen shrimps 4a and 4b are separated in this state.

Therefore, although the frozen shrimps 4 are stored close to each other, the mutual contact between them is cut off, and it becomes possible to pack or take out without touching other frozen shrimps 4. The frozen shrimp 4 will be sandwiched between the partition walls 2, and the displacement and other displacement in the container of the stored frozen shrimp 4 will be suppressed, and the frozen shrimp 4 can be placed stably and its eyes and whiskers. More effectively and reliably prevent defects such as tail, tail and the like. Furthermore, expand the storage space for the frozen shrimp 4 in the container.

According to a third aspect of the present invention, the partition walls 2 are formed in a zigzag shape so as not to be parallel to each other and the partition wall 2 and the side wall 20 of the box-shaped packaging container. Shape, fan-shaped, or the like. Therefore, the frozen prawns 4 are prevented from coming into contact with each other, and at the time of packing, as shown in FIG. 5, along the shape of the shrimp storage compartment 3 formed by the partition walls 2, that is, between the partition walls 2. The frozen headed prawns 4 should be stored so that the one with the wider interval becomes the head of the shrimp and the one with the narrower interval becomes the tail of the shrimp, which facilitates and speeds up the work. In addition, the storage space for the frozen shrimp 4 will be expanded to make more efficient use of the container.

In the invention according to claim 4, the cutout recesses 5 arranged in the partition wall 2 or the like at appropriate intervals downward from the top of the partition wall 2 form a frozen shrimp 4 picking port. , The frozen shrimp 4 enclosed and enclosed in the partition wall 2 and the like is grasped with the fingers of the body, and damages the eyes, whiskers, tails, etc. of the frozen shrimp individually and easily. It can be stored and taken out again.

[0024]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a container 1 for packaging a frozen shrimp according to the present invention of claim 1, which is a box-shaped top opening container integrally formed with a sheet of synthetic resin by a vacuum forming method or the like. In this example, soft polyvinyl chloride was used as the material. The size of the packaging container 1 is such that the depth from the upper end to the lower end of the bottom is about 3 cm, the long side is about 31 cm, and the short side is about 26 cm. However, it is formed by appropriately changing it according to the size of the frozen shrimp 4.

At the bottom of the inner surface of this frozen shrimp packaging container 1, a plurality of partition walls 2 are arranged in parallel with each other, and the shrimp is formed by these opposing partition walls 2 or the side wall 20 of the box-shaped packaging container. A storage compartment 3 is formed.

In the shrimp storage compartment 3, as shown in FIG. 4, the frozen shrimp 4 is stored so that the head and tail of the adjacent headed frozen shrimp are in the opposite direction.

In the case of the present embodiment, the distance X between the upper ends of the partition walls 2 (the short side width of the storage compartment 3) is about 2.5 cm, while the lateral width W of the body of the frozen shrimp 4 to be stored is W. Is about 2.8 cm, and when the shrimp are stored, the partition wall 2 is twisted along the shape of the frozen shrimps 4a and 4b.

When the distance X between the partition walls 2 is wider than the width W of the head and body of the frozen shrimp 4 to be stored, the frozen shrimp 4 can be prevented from contacting each other according to the present invention. Although the purpose is achieved, the clamping and fixing action does not work.

On the other hand, the frozen shrimp packaging container 1 can store the frozen shrimp 4 and can also store the raw shrimp and the like separately in the cold-frozen shrimp packaging container 1 to be frozen together with the container 1. Is. That is, in general, if a plastic container is frozen at a very low temperature, its viscosity is lost, and if it is twisted, it has a drawback that it breaks.However, by making it a thin plate, it can withstand such a freezing temperature and is deformed such as twisted. Was made possible.

Further, since the height H of the partition wall 2 is about 3 cm and is higher than the portion h related to the maximum value of the body width W of the frozen shrimp 4 as shown in FIGS. 6 and 7, the frozen shrimp is frozen. The shrimp 4a, 4b, 4c stored in parallel do not contact each other in the state where 4 is stored.

The height H of the partition wall 2 may be any dimension as long as it is higher than the portion h related to the maximum value of the lateral width W of the shrimp 4 body, but if it is too high, product placement, Since it becomes inconvenient in the display, and it becomes impossible to clamp and store the shrimp in the vertical direction of the container 1, as shown in FIG. 6, the dorsal apex 4a'4b'4c 'of the headed shrimp 4 etc. Therefore, it is desirable to set it to a slightly lower level. The partition wall 2 also serves as a grip for carrying the shrimp pack containing the frozen shrimp 4 with one hand, and also has a role of preventing a finger from directly touching the frozen shrimp 4.

Further, a notch concave portion 5 is provided downward from the top of the partition wall 2, and the concave portion 5 is provided when the frozen shrimp 4 stored in each storage chamber 3 is picked up with a finger. It becomes the mouth of Mami.

Note that the size, shape, and interval of the cutout recesses 5 are not limited, and may be extended below the portion h related to the maximum width of the shrimp body. However, in this case, the partition wall 2 must have a thickness that can prevent continuous freezing between the frozen shrimps 4 arranged in parallel.

Next, FIG. 8 shows a second embodiment of the packaging container 1 according to the present invention. The difference from the first embodiment is that the partition walls 2 are not parallel to each other, that is, zigzag. It is arranged in a shape. The zigzag arrangement allows the frozen shrimp 4 to be effectively stored separately. In this case, since the partition wall 2 is originally formed according to the shape of the frozen shrimp 4, the partition wall 2 holds the frozen shrimp 4 in place. In addition, the partition wall 2 does not have to be deformed, and therefore the material is not limited, and it is possible to use a foamable synthetic resin such as foamed polyethylene to further secure cold insulation and heat insulation. Manufacturing is easy.

FIG. 10 shows still another embodiment of the packaging container 1 according to the present invention. The difference from the above embodiment is that the partition wall 2 is formed in a curved shape. Since the headless shrimp is frozen in a bent shape, it is adapted to the frozen shape of this headless shrimp.

In addition, in order to obtain a large-capacity frozen shrimp packaging container 1, the partition walls 2 may be formed in multiple rows as shown in FIG.

[0037]

[Effect of device]

 Since the present invention adopts the above-mentioned configuration, according to the container for packaging frozen shrimp according to claim 1, the partition walls prevent the frozen shrimp from contacting each other. It can be stored, taken out, and used without touching it, and even if only a part of it is thawed, it does not induce the thawing of other frozen prawns and is re-frozen. However, there will be no situation in which frozen prawns are frozen together. In addition, defects such as eyes, whiskers, and tails of the frozen headed shrimp are prevented.

Further, the structure is simple and can be provided at low cost.

[0039] Next, according to the frozen shrimp packaging container of claim 2, packing and removal can be performed without touching other frozen shrimp, and unreasonable separation between frozen headed shrimps, etc. Defects such as eyes, whiskers, tails, etc. due to the can be more effectively and surely prevented, the storage space for the frozen prawns 4 is further expanded, and the frozen prawns are clamped by the partition wall, so that the mounted and held state is Stabilize.

According to the frozen shrimp packaging container of claim 3, in addition to the above-mentioned effects, it is not necessary to deform the partition wall, and therefore various synthetic resins are used in order to further secure cold insulation and heat insulation. It is also possible, and manufacturing becomes easier.

According to the frozen shrimp packaging container of claim 4, the frozen shrimp 4 stored in each case is damaged by individual eyes, whiskers, tails, etc. It can be stored and taken out easily by grasping it with a finger.
