BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for frozen fish and shellfish and a packaging method thereof.

[0002]

2. Description of the Related Art Frozen shrimp have been treated as frozen seafood as follows.

FIG. 8 is a perspective view showing a boxed frozen shrimp, and FIG. 9 is a perspective view showing a vacuum-packed frozen shrimp.

[0004] As shown in FIG. 8, shrimp (shrimp) 43 is frozen and packed together with ice 42 in a box 41 made of styrene foam or paper in order to maintain freshness when caught.
As shown in FIG. 9, it is vacuum-packed in a bag 44 made of polyethylene, vinyl, or the like, frozen, and commercially available.

[0005]

However, in any of the above-mentioned storage states, since a plurality of shrimps 43 are directly accommodated in one container, the shrimps 43 come into close contact with each other by freezing. In a state where the shrimp is frozen or integrated through the ice 42, and if the user tries to take out a necessary number of the food from the box 41 or the bag 44, the shrimp 4
Sometimes the feet and tail of 3 could be removed.

[0006] In particular, in the case of a vacuum-packed product, the foot or tail of the shrimp 43 may be similarly removed by the impact of loading or the like applied during distribution. If the shrimp 43 have not yet been removed in the distribution process, if they are completely thawed before being taken out of the container, the shrimp 43 will rarely be removed, but in this case, the shrimp 43 in one container will not be removed. Had to be thawed. Therefore, the thawed shrimp 43 could not be stored well, and all had to be used.

[0007] In addition, boxed frozen shrimp are usually thawed by immersing the whole box in water, and as the thawing progresses, tap water is flushed as needed to promote thawing at a stretch, so that the probability of breaking the legs increases. .

[0008] However, any frozen shrimp caused the juice to flow out by thawing, causing a peculiar odor, and the cooking environment was not good.

[0009] This type of problem is caused by other crustaceans such as shrimp and crab, cephalopods such as squid and octopus, and other seafood such as fish. Is basically the same.

Therefore, the present invention provides a method for preserving shrimp ,
An object of the present invention is to provide a package of frozen shrimp and a method of packaging the shrimp which do not impair the shape of the shrimp in the course of distribution and completion of cooking.

[0011]

A package of frozen shrimp according to the first aspect of the present invention is a frozen shrimp that has been rapidly frozen, and a small bag that is airtight and contains the frozen shrimp individually and is filled with gas. And a plurality of airtight pouches filled with the gas are accommodated together with the gas, and the plurality of pouches are paired with the plurality of pouches.
And an airtight large bag which is filled with gas twice .

[0012] According to this configuration, the fish and shellfish are stored in the large bag in a state of being individually stored in the small bag, so that a plurality of fish and shellfish directly contact in the large bag in the frozen state and are integrated in the frozen state. Or integrated through ice. Also, from inside the sachet where the seafood is individually stored ,
In order to gas doubly will have been filled, the pouch body is a cushion material to soften the impact from the outside.

Here, the gas to be filled in the small bag includes an inert gas such as nitrogen, the atmosphere (air), and the like.

In the package of the frozen shrimp of the second aspect, the gas filled in the small pouch is nitrogen. According to this configuration, the sea

BEST MODE FOR CARRYING OUT THE INVENTION A package of frozen shrimp of the present invention will be described below.
Each embodiment will be described as a packaging method .

Embodiment 1 FIG. 1 is a perspective view showing a packaged state of shrimp in a package of frozen fish and shellfish according to Embodiment 1 of the present invention, and FIG. 2 is a frozen fish and shellfish according to Embodiment 1 of the present invention. It is sectional drawing which shows the packaging state of a shrimp by the package of FIG. Throughout the embodiments, the same or corresponding members or portions are denoted by the same or corresponding reference numerals.

As shown in FIGS. 1 and 2, Embodiment 1
The package 1 for frozen fish and shellfish described above comprises five large pouches 2 accommodated in one large pouch 3. The large pouch 3 and the small pouch 2 are made of polyethylene, vinyl or the like, and are transparent, airtight and flexible, and each of the small pouches 2 is individually filled with a rapidly frozen shrimp 4 and filled with gas. ing. The five small pouches 2 containing shrimp 4 in this manner are accommodated together with gas in one large transparent and flexible pouch 3. In addition, the small bag body 2 and the large bag body 3
Although it is not necessarily limited to being transparent, it is preferable to be transparent to visible light because the state of the shrimp 4 inside can be confirmed.

According to the structure of the first embodiment, the shrimp 4 is rapidly frozen, so that
Since the adjacent shrimp 4 are not joined together, the shrimp 4 can be easily separated into individual pieces. That is, in the frozen state, the plurality of shrimp 4 are independent without being directly contacted or integrated via ice or integrated via ice.

Therefore, even when the shrimp 4 that has been rapidly frozen is individually housed in different small pouches 2, the whole is mechanically strengthened by freezing, so that the feet and tail of the shrimp 4 are not lost. , Can be accommodated. In addition, when the shrimp 4 is cooked or when the shrimp 4 is taken out from the small pouch 2, the legs and tail of the shrimp 4 can be prevented from falling off.

Furthermore, a small bag 2 in which shrimp 4 are individually placed.
Since the inside is filled with gas, it serves as a cushioning material for cushioning an external impact on the small pouch body 2.
The shrimp 4 may also be affected by the impact of the shrimp 4 during the distribution process or the impact of removing the required number of shrimp 4 from the large bag during cooking.
It is possible to prevent the legs, tails, etc. of the fish from dropping, and to take out only the required number of shrimps 4 from the large bag 3 and thaw them.

The gas to be charged into the small bag 2 is
Air is preferred because of its workability and cost. Also, in particular,
It is preferable to use an inert gas such as nitrogen because it is possible to prevent quality deterioration due to oxidation of the shrimp 4.

Second Embodiment Next, a second embodiment will be described.

FIG. 3 is a cross-sectional view showing a packaged state of two shrimp in a package of frozen seafood according to the second embodiment of the present invention, and FIG. 4 is a sectional view of the frozen seafood according to the second embodiment of the present invention. Sectional drawing which shows the packaging state of three shrimp by a package, FIG.
Fig. 4 is a cross-sectional view showing a packaged state of ten shrimps in a package of frozen seafood according to a second embodiment of the present invention. FIG.
FIG. 4 is a table showing an example of the number of shrimp supply that can be expressed by a combination of packaging in each embodiment.

A package 11 of frozen fish and shellfish according to the second embodiment shown in FIG. 3 has two small pouches 2 for individually storing shrimp 4 in one large pouch 3.

A package 21 of frozen fish and shells according to the third embodiment shown in FIG. 4 has three small pouches 2 for individually storing shrimp 4 in one large pouch 3.

A package 31 of frozen fish and shellfish according to the fourth embodiment shown in FIG. 5 has ten small pouches 2 for individually storing shrimp 4 in one large pouch 3.

As described above, the small bag 2 is contained in one large bag 3.
Of frozen fish and shellfish of different numbers to accommodate
1 and 31 also use the same manufacturing method as the frozen seafood package 1 of the first embodiment, and have the same operational effects.

The small bags 2 accommodated in different numbers in one large bag 3 have the following reasons.

First, the packages 11 and 21 of the frozen seafood according to the second embodiment will be described.

The package 11 of the frozen seafood according to the second embodiment,
If 21 are combined, the number of shrimp 4 that can be purchased at a time by the consumer can be varied.

That is, the number of shrimp 4 that can be supplied alone in the package 11 or 21 of the frozen seafood of the second embodiment is two or three, and the number of shrimp 4 is shown in FIG. In this case, two or more arbitrary shrimp 4 can be supplied.

FIG. 6 shows a package 11 of frozen seafood according to the second embodiment for obtaining a supply number of shrimp 4 from 2 to 12.
Although 21 combinations are shown, any number of shrimp 4 to be supplied can be obtained by combining the packaging of each embodiment.

That is, natural numbers other than 2, 3 and 2 or more are 2 + 2 = 4, 2 + 3 = 5, 3 + 3 = 6, 2 + 2 + 3
= 7,2 + 3 + 3 = 8,3 + 3 + 3 = 9,2 + 2 + 3 +
3 = 10, 2 + 3 + 3 + 3 = 11,3 + 3 + 3 + 3 = 1
It can be represented by the number of additions obtained by combining 2 and 3, such as 2.

For this reason, the seller has two shrimp 4
Consumers can purchase any two or more shrimp 4 as needed simply by making the two types of frozen seafood packages 11 and 21.

However, the two types of frozen seafood packages 11 and 21 in which the number of shrimp 4 accommodated are two and three, however, are complicated for traders who purchase large quantities. Therefore, if five or ten packs are prepared as in the case of the frozen seafood packages 1 and 31, the purchase quantity can be determined efficiently without fail.

In use, the shrimp 4 is kept fresh in a state where the shrimp 4 is kept frozen in a state where the required number of the shrimp taken out from the large bag 3 are thawed and the others are stored in the small bag 2.

In each of the above embodiments, the shrimp 4 is stored in the pouch 2, but the shrimp 4 is stored in the pouch 2.
Other crustaceans such as crabs, cephalopods such as squid and octopus, and other seafood such as fish may be accommodated. Even if these other fish and shellfish are stored in the small pouch 2, the same operation and effect as those of the above-described embodiments can be obtained.

Next, a method for packaging shrimp 4 using the frozen fish and shells 1, 11, 21, 31 according to the first and second embodiments will be described.

FIG. 7 is a block diagram showing a shrimp packaging process by packaging according to each embodiment of the present invention.

As shown in FIG. 7, step S1 is a rapid freezing step of rapidly freezing fish and shellfish. For example, a plurality of shrimps 4 are rapidly frozen in a box, and the plurality of shrimps 4 are individually separated. It is in a state where it can be done. In the case of quick freezing, the shrimp 4 are individually frozen and do not become in a frozen state in which they are connected to each other, so that they can be individually separated. The process moves to a step of individually putting the plurality of shrimp 4 that have been rapidly frozen into the small pouches 2.

Step S2 is a step of accommodating the seafood quickly frozen in the airtight small bag body 2, that is, the seafood small bag accommodating the shrimp 4 together with the gas.

The shrimp 4 that has been rapidly frozen is housed in the small pouch 2 so that it can be sealed with air alone. At this time, if the small bag 2 is opened, air enters through the opening, and if the shrimp 4 which is rapidly frozen is stored in that state, the shrimp 4 and the air can be stored together in the airtight small bag 2. It can be manufactured inexpensively because of good work efficiency and no need to use special gas. Of course, shrimp 4
May be sealed by blowing an inert nitrogen gas onto the small bag 2. That is, it is possible to provide a gas filling step in which the space inside the small bag body 2 is filled with gas while maintaining a sealed state with the outside. In this case, the shrimp 4 and nitrogen can be stored together in the airtight small bag body 2. In any case, since the shrimp 4 that has been quickly frozen is kept in a dry state, the transparency of the small bag 2 can be ensured even in a frozen state by using a dry air or nitrogen gas.

Step S3 is a step of accommodating a large bag of fish and shellfish, in which a plurality of small pouches 2 containing shrimp 4 and gas are accommodated together with gas. This large-sized seafood bag accommodation step is a step of using a plurality of small pouches 2 containing both shrimp 4 and gas to put them in one large pouch 3.

In the step S3, a number of small bags 2 corresponding to the type of the large bag 3 of each embodiment are stored.
The number of small pouches 2 accommodated in one large pouch 3 is based on 2, 3, 5, 10 in the above embodiments, but may be other values.

Therefore, according to the configurations of the packages 1, 11, 21 and 31 of the frozen fish and shellfish according to the first and second embodiments, the shrimp 4 are individually stored in different small bags 2 and the large bag 3 In the distribution and storage state, the shrimp 4 do not directly contact and integrate with each other in the large bag body 3 nor integrate via ice. Therefore, only the required number of shrimps 4 can be taken out from the large bag 3 and thawed without dropping the feet and tail of the shrimps 4 and used. In addition, since the inside of the small pouch 2 into which the shrimp 4 is individually placed is filled with gas, the small pouch 2 serves as a cushioning material for cushioning an external impact, and the shrimp 4 may be used in the course of the shrimp 4 during distribution and during cooking. It is possible to prevent the feet and tail of the shrimp 4 from being lost due to a work error or the like when removing the 4 from the large bag 3.

In the configuration of the frozen fish and shell wrappings 1, 11, 21, 31 according to the first and second embodiments, when the gas filled in the small bag 2 is an inert gas such as nitrogen, Since the shrimp 4 is filled with the inert gas, it is possible to prevent the shrimp 4 from coming into contact with oxygen and prevent the shrimp 4 from deteriorating due to oxidation.

According to the configuration of the frozen fish and shell wrappers 11 and 21 according to the first and second embodiments, the large bag 3 is composed of a plurality of types in which the number of small bags 2 is accommodated.
The consumer can purchase a desired number of shrimps 4 by selecting a plurality of types of large sacks 3 accommodating different numbers of shrimps 4 according to the number of small sacks 2 accommodated. In addition, by appropriately combining the large bags 3 having different numbers of shrimp 4 accommodated therein, the number of shrimp 4 that can be purchased at once by the consumer can be varied. As described above, the standard of the large bag body can be set to about two kinds, and the material cost can be reduced by the standardization.

According to the method for packaging shrimp 4 using the frozen fish and shellfish packages 1, 11, 21, 31 according to the first and second embodiments, the large pouches are individually stored in different small pouches 2. Since the prawns 4 are accommodated in the large bag 3 in the frozen state, the shrimp 4 does not come into direct contact with each other to be integrated or integrated via ice. Therefore, only the required number of shrimps 4 can be taken out from the large bag 3 and thawed without dropping the feet and tail of the shrimps 4 and used. Further, since the gas is filled in the small pouch 2 into which the shrimp 4 is individually placed, the small pouch 2 serves as a cushioning material for cushioning the shock applied from the outside. When the prawns 4 are taken out of the large bag body 3, it is possible to prevent the prawns 4 from dropping their feet, tails, and the like due to a mistake in taking out.

Further, in the packaging method of shrimp 4 using the frozen seafood packaging bodies 1, 11, 21 and 31 according to the first and second embodiments, when the gas filled in the small bag body 2 is an inert gas, Since the shrimp 4 is filled with the inert gas, contact with oxygen can be prevented, and quality deterioration due to oxidation of the shrimp 4 can be prevented.

In addition, according to the packaging method of shrimp 4 by the frozen fish and shell wrappings 1, 11, 21, 31 according to the first and second embodiments, the number of the large pouches 3 to accommodate the small pouches 2 is different. The consumer selects the large bag 3 containing the required number of shrimps 4 from the multiple types of large bags 3 containing the shrimp 4 in different numbers according to the number of small bags 2 contained therein. Thus, the desired number of shrimps 4 can be purchased. In addition, by appropriately combining the large bags 3 having different numbers of shrimp 4 accommodated therein, the number of shrimp 4 that can be purchased at once by the consumer can be varied.

By the way, in the above-described embodiment, the case of shrimp is described as frozen fish and shellfish. However, when the present invention is practiced, crustaceans such as shrimp, crab, etc. may be used as frozen fish and shellfish other than shrimp. , Squid, octopus, etc. and fishes. Some of these are more significant in that the generation of odor when thawed can be suppressed than the change in shape.

Further, only the large bag and the small bag are unnecessary after use, and a material such as styrofoam is not used, which is suitable for waste treatment. In particular, by using a biodegradable vegetable synthetic resin for the large bag and the small bag, the package is unrelated to pollution.

[0059]
