Description

Technical Field

[0001] The utility model relates to the technical field of fish transportation packaging, and particularly relates to a live fish packaging bag. Background Art

[0002] During the long-distance transportation of fresh seafood, it is extremely easy to die in large numbers due to reasons such as lack of oxygen and pollution, thus losing its original economic value. Especially for some live fish products with extremely fragile vitality, during transportation, a large amount of oxygen-supplying and power supply equipment needs to be carried to provide the conditions required for the survival of live fish products. These equipment and power sources are very bulky, occupying a large amount of transportation space, wasting transportation costs, and the open oxygen supply is likely to pollute the survival environment of live fish products, resulting in a large number of fish deaths.

[0003] Therefore, the patent with the application number CN201410140070.7 discloses a transportation oxygen bag for live fish. The transportation oxygen bag for live fish is a bag body with one side open and the periphery sealed, consisting of an upper layer and a lower layer. After injecting oxygen, a separately provided binding belt is used to tie and seal the bag mouth to increase the survival time of fish. However, the opening of the transportation oxygen bag is relatively large. Especially when the caliber of the bag mouth is quite different from that of the oxygen delivery pipe, air is easily mixed into the oxygen bag during the oxygen injection process, reducing the oxygen storage capacity in the bag, thereby reducing the survival time of fish. Moreover, the separately provided binding belt is easy to lose when not in use and also takes time to find when needed, making it not very convenient to use. Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a live fish packaging bag, which can prevent air from being mixed in during oxygen injection, and integrates a fastener for sealing, which can be used at any time and prevent loss.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A live fish packaging bag includes a bag body and a bag mouth. The bag body is used for holding live fish, and the bag mouth communicates with the bag body to inject water and oxygen. An elastic member that can automatically tighten the bag mouth is provided at the opening of the bag mouth; a fastener is provided between the bag body and the elastic member on the bag mouth to seal the bag body.

[0007] As an optional solution, the elastic member is a rubber ring.

[0008] As an optional solution, a limiting channel is fixedly connected to the bag mouth along the circumferential direction, and the middle part of the fastener is penetrated and arranged in the limiting channel.

[0009] As an alternative solution, the fastener includes a fixing rope; the fixing rope is arranged around the bag mouth; a plurality of clamping protrusions are arranged along the length direction at the first end of the fixing rope, and a clamping sleeve capable of being clamped with the clamping protrusions is arranged at the second end of the fixing rope. The fixing rope is tightened to clamp the corresponding clamping protrusions on the clamping sleeve to seal the bag body.

[0010] As an alternative solution, the clamping sleeve includes a connecting plate and elastic flaps; one end of the connecting plate is connected to the second end of the fixing rope, and a connecting hole through which the first end of the fixing rope can pass is formed at the other end of the connecting plate; a plurality of elastic flaps are arranged, and the plurality of elastic flaps are fixedly connected around the connecting hole on one side surface of the connecting plate, and the elastic flaps are inclined towards the center of the connecting hole; the clamping protrusion is coaxially and fixedly connected to the fixing rope. The first end of the fixing rope is passed through the connecting hole from the other side surface of the connecting plate, so that the clamping protrusion squeezes open the plurality of elastic flaps and is clamped on the elastic flaps after the elastic flaps return to their original state.

[0011] As an alternative solution, the clamping protrusion is in the shape of a flat-top cone, and the small end of the clamping protrusion is close to the connecting plate.

[0012] As an alternative solution, a protective pipe sleeve sleeved outside the elastic flaps is fixedly connected to the connecting plate.

[0013] Due to the adoption of the above technical solution, the present utility model will have the following beneficial effects:

[0014] A live fish packaging bag provided by the present utility model is provided with a tightening member capable of automatically tightening the bag mouth at the opening of the bag mouth. In this way, during the oxygen supply process, the bag mouth can fit the oxygen supply pipe under the action of the contraction force of the tightening member, thereby preventing air from entering the bag body and affecting the survival time of fish. At the same time, the automatic tightening design can also improve work efficiency. By providing a fastener for sealing the bag body on the bag mouth, that is, integrating the fastener on the bag mouth, the fastener can be used at any time and the loss of the fastener can be prevented.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Please refer to Figure 1 and Figure 2 In one embodiment of a live fish packaging bag of the utility model, the live fish packaging bag includes a bag body 1 and a bag opening 2. The bag body 1 can be set to be rectangular and used to hold live fish; the bag opening 2 is connected to the bag body 1 and is used to inject water and oxygen necessary for the survival of live fish into the bag body 1.

[0027] Among them, an elastic member 3 that can automatically tighten the bag mouth 2 is provided at the opening of the bag mouth 2. When oxygen needs to be injected, the bag mouth 2 is stretched open to connect the oxygen supply tube. The bag mouth 2 is automatically tightened on the oxygen supply tube under the action of the elastic member 3. In this way, air is not easily mixed into the bag body 1 when oxygen is injected, and the oxygen storage in the bag body 1 is increased, thereby increasing the survival time of the fish. It should be noted that the caliber of the bag mouth 2 in the prior art is generally designed to be smaller than the bag body 1 and not too small to facilitate the connection of oxygen supply tubes of various sizes. When the bag mouth 2 is connected to the oxygen supply tube, in order to improve work efficiency, the staff usually directly tightens the bag mouth 2 on the oxygen supply tube by hand. In this way, if the caliber of the bag mouth 2 differs too much from the caliber of the oxygen supply tube, a gap is easily formed between the bag mouth 2 and the oxygen supply tube, resulting in the mixing of air into the bag body 1. The elastic member 3 can make the bag mouth 2 fit the oxygen supply tube, so even when the caliber of the bag mouth 2 differs too much from the caliber of the oxygen supply tube, it can prevent the mixing of air. At the same time, the automatic tightening design can also improve work efficiency.

[0028] Among them, a fastener 4 is provided on the bag opening 2 between the bag body 1 and the elastic member 3 to seal the bag body 1. After the bag body 1 is filled with fresh fish and filled with a little water and oxygen, the bag body 1 is sealed by the fastener 4 to prevent oxygen and water from leaking out, so that the fresh fish can be stored for a long time without dying or spoiling. It should be noted that the prior art uses a separately provided strapping tape to seal the bag body 1, which is easy to lose when not in use and takes time to find when needed, while the fastener 4 is integrated on the bag opening 2 and can be used at any time and prevented from being lost.

[0029] Specifically, the elastic member 3 can be set as a rubber ring, which is made of rubber material. Its unique elasticity makes it an excellent sealing material, which can be used in various devices and machines to prevent liquid or gas leakage. In this embodiment, the rubber ring as the elastic member 3 can make the bag opening 2 fit the oxygen delivery tube well and prevent the bag body 1 from mixing with air.

[0030] Specifically, a limiting channel 21 can be fixedly connected along the circumference on the bag mouth 2. The middle part of the fastener 4 is arranged through the limiting channel 21. After tightening the fastener 4, both ends of the fastener 4 exposed from the limiting channel 21 are fixed to seal the bag body 1. The above-mentioned limiting channel 21 plays a limiting role on the fastener 4, that is, while not affecting the tightening action of the fastener 4, it restricts the movement of the fastener 4, thereby preventing the loss of the fastener 4.

[0031] Please refer to Figures 3 - 6 , the fastener 4 can be set to include a fixing rope 41; the fixing rope 41 passes through the limiting channel 21 and is arranged around the bag mouth 2; a plurality of clamping protrusions 42 are arranged along the length direction at the first end of the fixing rope 41, and a clamping sleeve 43 that can be clamped with the clamping protrusion 42 is arranged at the second end of the fixing rope 41. After tightening the fixing rope 41, the corresponding clamping protrusion 42 is clamped on the clamping sleeve 43 to seal the bag body 1.

[0032] Specifically, the clamping sleeve 43 can be set to include a connecting plate 431 and elastic flaps 432; one end of the connecting plate 431 is connected to the second end of the fixing rope 41, and a connecting hole 4311 through which the first end of the fixing rope 41 can pass is opened at the other end of the connecting plate 431; the elastic flaps 432 can be made of rubber material, and there are a plurality of them. The plurality of elastic flaps 432 are fixedly connected around the connecting hole 4311 on one side of the connecting plate 431, and the elastic flaps 432 are inclined towards the center of the connecting hole 4311; the clamping protrusion 42 is coaxially fixedly connected to the fixing rope 41. When it is necessary to lock the fastener 4, the first end of the fixing rope 41 is passed through the connecting hole 4311 from the other side of the connecting plate 431. One end of the clamping protrusion 42 squeezes open a plurality of elastic flaps 432 so that the elastic flaps 432 turn upwards. After the clamping protrusion 42 completely passes through the elastic flaps 432, the elastic flaps 432 lose the restriction of the clamping protrusion 42 and thus turn downwards to restore the original state under the action of the elastic restoring force, so that the other end of the clamping connection is clamped on the elastic flaps 432 under the action of the fixing rope 41 to fix both ends of the fixing rope 41.

[0033] More specifically, the clamping protrusion 42 can be set in the shape of a flat-top cone, and the small end of the clamping protrusion 42 is close to the connecting plate 431. In this way, the small end of the clamping protrusion 42 is easier to squeeze open the elastic flaps 432, and the large end of the clamping protrusion 42 can also be more stably clamped on the elastic flaps 432.

[0034] Furthermore, a protective tube sleeve 433 sleeved outside the elastic flaps 432 can be fixedly connected to the connecting plate 431. The protective tube sleeve 433 can be made of hard plastic, so that the protective tube sleeve 433 has relatively high hardness and rigidity, and can avoid the influence of the outside world on the turning of the elastic flaps 432.

[0035] The usage method or working principle of the present utility model is as follows:

[0036] First, open the fastener 4 and expand the tensioning member 3, and put live fish and a small amount of water into the bag body 1 from the bag mouth 2; then put the bag mouth 2 on the oxygen delivery tube and at the same time release the tensioning member 3 so that the bag mouth 2 fits the oxygen delivery tube under the action of the contraction force of the tensioning member 3, and then fill the bag body 1 with oxygen through the oxygen delivery tube; after the bag body 1 is filled with oxygen, tighten and fix the fastener 4 to seal the bag body 1.

[0037] Since the bag mouth 2 fits the oxygen delivery tube during the oxygen delivery process, it can prevent air from mixing into the bag body 1 and affecting the survival time of the fish. Since the fastener 4 is integrated on the bag mouth 2, the fastener 4 can be used at any time and the loss of the fastener 4 can be prevented.

[0038] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
