Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a storage bag that is filled with seawater or the like and stores live fish.

[Conventional technology]

BACKGROUND ART Conventionally, as a storage bag for storing live fish used for fishing or the like, a cylindrical bag whose upper opening is tied with a string has generally been used. For example, in 1975
Japanese Patent No. 147170 proposes a storage bag that includes a sealing string attached near the upper end of the storage bag and a suspension string for suspending and supporting the storage bag.

However, if you try to seal the storage bag with a string as described above, () it takes time to tie the string, () it doesn't look good, and () you need extra money to tie the string. Various problems have arisen, such as a reduction in the volume of the storage bag and () an inability to ensure sufficient sealing performance. Particularly when using a large-capacity storage bag, if the bag is sealed with a string, the work of closing the opening of the storage bag and tying the string is extremely time-consuming.

Therefore, in order to avoid the above trouble, we decided to
BACKGROUND ART A container for transporting and storing live fish etc. disclosed in Japanese Utility Model Publication No. 60-2770 and a cold storage container for fishing disclosed in Japanese Utility Model Application Publication No. 60-144874 are known.

In the above-mentioned transportation/storage container, a part of the upper wall of the rectangular container is provided with an access opening extending upward and both ends welded together, and two fasteners are provided on the inside and outside of the access opening. ing.

Therefore, when the two fasteners of the entrance/exit opening are open, both ends of the entrance/exit opening are welded, and therefore, the rectangular container containing water, live fish, etc. cannot be pulled in the direction of opening the entrance/exit opening. The tensile force is supported by both ends.

As a result, the entrance/exit opening does not open wide and there is no need to support the entrance/exit opening, for example, by hand, so that live fish and the like can be easily stored in the rectangular container.

On the other hand, in the above-mentioned cold storage container for fishing, a long opening made of a flexible material that can be rolled up and has a reinforcing core material inside the opening is integrally provided in the upper part of the cylindrical cold storage bag, and the elongated opening is made of a flexible material that can be rolled up. A plurality of bands are provided so that they can be wound at least once, and both ends of the bands can be engaged to fix the elongated opening into which they are wound.

Therefore, the inside of the cylindrical cold bag can be sealed by storing the fish in the cylindrical cold bag through the elongated opening, using the reinforcing core material as a core, and securing the fish with a band that wraps around the long opening. The inside of the cold bag can be kept cold by placing a refrigerant in the form of a bag inside the bag.

[The problem that the idea aims to solve]

However, in the conventional transportation/storage container,
A problem arises in that it takes time to store live fish in a square container. In other words, when storing live fish with the entrance/exit opening open, since both ends of the entrance/exit opening are welded, the opening of the entrance/exit opening becomes smaller, and when storing moving live fish. It is thought that it takes time to come into contact with the entrance/exit opening and store the live fish intact in the rectangular container.

Further, in the conventional cold storage container for fishing, there is a problem in that the base end of the elongated opening is easily torn, resulting in loss of sealing performance and deterioration of cold storage performance. That is, the elongated opening is pulled in the opening direction by the cylindrical cold bag containing water, and further,
In order to improve the sealing performance, the elongated opening is rolled up tightly, so that the proximal end of the elongated opening is in a taut state when the elongated opening is rolled up. Moreover, the band securing the elongated opening is adapted to only partially cover said elongated opening.

For this reason, in the fishing cooler container, the elongated opening made of a flexible material is easily torn due to contact with the protruding material, which impairs the sealing performance of the cylindrical cooler bag and prevents cold storage. is thought to deteriorate.

The purpose of this invention is to be able to store live fish without damage.
Further, it is an object of the present invention to provide a storage bag that can reduce the reduction in the survival period of live fish by maintaining airtightness and ensuring cold retention.

[Means to solve the problem]

In order to solve the above problems, the storage bag for live fish according to the present invention includes a storage bag main body having an opening,
A cylindrical storage pocket whose distal end can be sealed and whose proximal end is attached around the opening of the storage bag main body; and a cylindrical storage pocket that is longer than the storage pocket and has a sealing section at the distal end A flexible bag having a proximal end attached to the peripheral edge of the opening of the storage bag main body within the storage pocket so that it protrudes from the storage pocket when expanded, and is stored within the storage pocket when folded. It is characterized by having a sex introduction tube.

[Effect]

In the above configuration, when closing the opening of the storage bag main body, first seal the tip of the introduction/exit tube, and then roll the introduction/exit tube into a roll shape, for example, with the sealed portion as a core. Fold it up and store it in the storage pocket, and then seal the tip of the storage pocket.

In this way, you can save the trouble of tying the opening of the storage bag body with a string, which simplifies the sealing work, and when the bag is sealed, the introduction tube is stored inside the storage pocket, so it looks good. Moreover, the volume of the storage bag body does not decrease in the sealed state.

In addition, the leakage prevention effect achieved by doubly sealing the tip of the inlet/outlet tube and the tip of the storage pocket, combined with the leakage prevention effect achieved by tightly folding and fixing the inlet/outlet tube within the storage pocket with the sealed part as a core, results in sufficient sealing.

Furthermore, live fish can be taken in and out of the storage bag body with the introduction/extraction tube extended and protruding from the storage pocket. This makes it possible to easily introduce live fish into the storage bag body without damage through the relatively long and flexible introduction tube, especially during introduction, and also prevents water from overflowing during introduction. .

Furthermore, in the above configuration, the base end of the lead-out tube is provided at the periphery of the opening of the storage bag main body, and the base end of the storage pocket is provided around the opening. The stored and sealed storage pocket can cover the folded lead-in/out tube with a gap, and on the other hand, when the lead-in/out tube is tightly folded, its restoring force is small. Become.

Therefore, the storage bag main body that stores water and live fish can reduce the force that pulls the side walls of the storage pocket away from each other, thereby avoiding the tension of the side walls. be done.

As a result, the above-mentioned structure can reduce tearing of the storage pocket even if the projecting member comes into contact with the storage pocket that houses and seals the lead-in/out tube.

In this way, the above configuration allows for smooth loading and unloading of live fish, prevents damage to the proximal end of the introduction/exit tube that would reduce sealing performance, and further improves sealing performance.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

As shown in FIG. 1a, a storage bag 1 for storing live fish such as fish and shellfish includes a hollow storage bag main body 2 that is long in the front and back direction, and the storage bag main body 2 can accommodate, for example, three sea breams. It is designed to have a relatively large volume so that it can accommodate a large amount of storage space. As shown in FIG. 3, a long opening 3 extending in the front-rear direction is provided at the center of the upper surface of the storage bag main body 2.

A cylindrical storage pocket 4 is arranged around the opening 3. Then, as shown in Figure 2a,
The base end of the storage pocket 4 is welded to the upper surface of the storage bag main body 2, so that the storage pocket 4 is attached to the upper surface of the storage bag main body 2 so as to surround the opening 3.

As shown in FIG. 4, the storage pocket 4 is formed into a cylindrical shape by welding two rectangular sheets 5 and 6 at both front and rear ends. Button recesses 7a, 7a are attached to the upper part of one rectangular sheet 5 forming the tip of the storage pocket 4, and button convex parts 7b, 7b that engage with the button recesses 7a, 7a are attached to the upper part of the other sheet 6. is attached and the button recess 7
By engaging the button protrusions 7b, 7b with the buttons a, 7a, the tip of the storage pocket 4 is sealed. Note that the storage pocket 4 may be integrally molded as a cylindrical body.

Inside the storage pocket 4, a flexible introduction/extraction tube 8, which is longer than the storage pocket 4 in the vertical direction, is arranged at the periphery of the opening 3. As shown in FIG. 2a, the base end of the introduction/exit tube 8 is welded to the upper surface of the storage bag main body 2 in the same way as the base end of the storage pocket 4, so that the introduction/exit tube 8 is welded to the upper surface of the storage bag body 2. It is attached to the periphery of the opening 3.

As shown in FIG.
A cylindrical shape is formed by welding two rectangular sheets 10 and 11 at both front and rear ends. As shown in FIG. 6, on the inner surface side of the tip end of one sheet 10, a protrusion 12a extending in the front-rear direction,
12a... are formed, and adjacent protrusions 12a,
Projections 12b, 12 that removably fit between 12a
b is formed. These protrusions 12a, 12a
... and the protrusions 12b, 12b constitute a fastener 12 as a well-known engagement type sealing part, and the tip of the introduction/exit tube 8 is sealed by the fastener 12.

On the upper surface of the storage bag main body 2 outside the storage pocket 4, there is provided an air supply/exhaust section 13 which can be opened and closed and is used for injecting oxygen into the storage bag main body 2.
Note that various synthetic resin films such as polyvinyl chloride film, polyethylene film, polyvinylidene chloride film, polypropylene film, etc. can be suitably used as materials for the storage bag body 2, storage pocket 4, and introduction/output tube 8. However, it is particularly preferable to use a transparent film such as polyvinyl chloride film so that the live fish inside can be observed. The thickness of the storage bag main body 2 and the storage pocket 4 is, for example, about 0.3 mm, and the introduction/output tube 8 has a thickness of about 0.3 mm.
It is made thinner, for example, about 0.1 mm.

In the above configuration, water, live fish, etc. can be introduced into the storage bag main body 2 through the button recesses 7a, 7 of the storage pocket 4, as shown in FIGS. 1a and 2a.
a and the button protrusions 7b, 7b are separated, the storage pocket 4 is opened, the introduction/extraction tube 8 is extended and protruded from the storage pocket 4, and the fastener 12 is opened, and the introduction/extraction tube 8 is opened. Do it through. In this way, by introducing live fish through the relatively long introduction/output tube 8, the introduction can be carried out smoothly and without any damage, and at the same time, it is possible to prevent the introduction from the storage bag main body 2 due to the introduction. It also prevents water from overflowing. Further, the removal of live fish from the storage bag main body 2 and drainage can be similarly performed via the introduction/extraction tube 8.

Next, when sealing the opening 3 after introducing live fish, first close the fastener 12 at the tip of the introduction/output tube 8, and then
As shown in FIG. 3, the introduction/exit tube 8 is folded and stored in the storage pocket 4 by, for example, being rolled into a roll, using the fastener 12 as a core.
Subsequently, the button convex portion 7 is placed in the button concave portions 7a, 7a.
By engaging b and 7b, the storage pocket 4
Seal the tip of the

In addition, if transporting live fish requires a long time, the water temperature in the storage bag body 2 may be lowered to slow down the activity of the live fish to prevent damage to the live fish or to prevent the transport from occurring. It is possible to take measures such as replenishing oxygen from the supply/exhaust section 13 during the process.

Even in such a case, the structure of the above embodiment is such that the introduction/exit tube 8 is folded and stored in the storage pocket 4 and fixed, so that the tip of the introduction/exit tube 8 can be secured to be sealed. Sealing performance can be maintained, a decrease in oxygen concentration within the storage bag body 2 can be suppressed, and cold retention can be ensured when a bag-like refrigerant is introduced.

At this time, the introduction/exit tube 8 can maintain the sealed state at its tip and maintain its sealing property, and
Since it is folded tightly so that it can be miniaturized, its proximal end becomes taut.

By the way, conventionally, when the tip of a knife-like object comes into contact with the proximal end of the elongated opening in the folded and stretched state as described above, lacerations easily occur in the proximal end. If the internal airtightness could no longer be maintained, the concentration of the enclosed oxygen, etc. would drop, and the cold retention would deteriorate, shortening the survival period of the stored live fish and the storage period of the fish. .

However, in the configuration of the above embodiment, the folded introduction/exit tube 8 is stored, and the storage pocket 4 is provided which is thicker and more durable than the introduction/exit tube 8, and furthermore, the distal end thereof can be sealed. , when the proximal end of the introduction/exit tube 8 in a taut state comes into contact with, for example, the tip of a knife-like object,
This can be prevented by the storage pocket 4 mentioned above.

Therefore, the above configuration can prevent lacerations that are likely to occur in the introduction/exit tube 8 which is folded so as to maintain sealing performance, so that sealability can be ensured.
For example, a decrease in the concentration of injected oxygen or the like can be suppressed. As a result, the above structure can further prevent damage when taking live fish in and out, compared to the conventional method.
This makes it possible to avoid shortening the survival period of stored live fish.

Such a storage bag 1 can be used not only for fishing, but also for delivering live fish as a gift to the recipient's home, for transporting live fish by ocean routes, and for use at markets, fish stores, etc. It can also be used as a container for selling live fish.

FIG. 7 shows a modification, in which, in addition to the configuration of the above embodiment, a storage bag 1 is attached to the storage bag main body 2.
A band 14 for gripping is attached.

In the above embodiment, a button consisting of a button recess 7a and a button protrusion 7b is used to seal the storage pocket 4, but a fastener or the like may be used instead.

[Effect of idea]

As described above, the storage bag for live fish according to the present invention includes a storage bag main body having an opening, a distal end that can be sealed, and a proximal end that is attached around the opening of the storage bag main body. a cylindrical storage pocket, which is longer than the storage pocket, has a sealing part formed at its distal end, and has a proximal end attached to the periphery of the opening of the storage bag body within the storage pocket; This structure includes a flexible introduction/extraction tube that is extended from the storage pocket when expanded, and is stored within the storage pocket when folded.

As a result, when closing the opening of the storage bag main body, first seal the tip of the inlet/outlet tube, fold the inlet/outlet tube and store it in the storage pocket, and then close the tip of the storage pocket. This simplifies the sealing process by eliminating the need to tie the opening of the storage bag with string, and also improves the appearance of the bag because the introduction tube is stored inside the storage pocket. Moreover, the volume of the storage bag body does not decrease in the sealed state.

In addition, the leakage prevention effect is achieved by doubly sealing the tip of the introduction/output tube and the tip of the storage pocket, and the introduction/output tube can be folded and fixed within the storage pocket with the sealing portion as a core. Combined with the leakage prevention effect, sufficient sealing performance can be obtained.

Furthermore, live fish can be taken in and out of the storage bag body with the introduction/output tube protruding from the storage pocket, so live fish can be introduced through the relatively long introduction/output tube, especially during introduction. In addition to being able to do this smoothly and without damage, it also prevents water from overflowing during installation.

Furthermore, by providing a storage pocket for storing the introduction/exit tube, the above configuration can avoid tearing the proximal end of the folded introduction/exit tube, thereby ensuring the sealing performance of the storage bag main body. For example, it is possible to suppress a decrease in the concentration of oxygen, etc. injected into the storage bag main body, and it is also possible to ensure cold retention.

As a result, the above configuration can prevent damage to live fish during loading and unloading, while also preventing deterioration of sealing performance, suppressing a decrease in the concentration of injected oxygen, etc., and preventing deterioration of cold storage performance. Because it can reduce
This has the effect of avoiding a reduction in the survival period of stored live fish.
