Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of self-supporting packaging bags of cold preservation. BACKGROUND

[0002] The current existing refrigeration mode is all single packaging, and most are ice bags, one is biological ice bag, which contains refrigerant, is configured by high-tech biological material, is in the form of gel body, and needs to be placed in refrigerator for freezing when used;Another is water injection ice bag, which contains refrigerant and needs to be watered when used, and the use method is the same as that of biological ice bag, and both are commonly used for cold storage and transportation.The common refrigeration method in life is to freeze in refrigerator or add ice cubes for refrigeration.Few people will always keep ice bags, and if drinks are placed in refrigerator for freezing, they need to be thawed when drinking, which not only consumes time, but also may affect the quality and nutritional ingredients of drinks if thawing and freezing frequently;Adding ice cubes to drinks will change the taste of drinks, such as coffee, juice, etc., which will be diluted due to the melting of ice cubes, and the taste will be greatly reduced.

[0003] In addition, for some scenes that need to maintain low temperature for a long time outdoors, such as picnic, outdoor sports, etc., whether it is an ice bag or a cold drink taken out from the refrigerator, it is difficult to maintain low temperature for a long time.The refrigeration effect of the existing ice bag will gradually decrease after multiple uses, and the quality of some ice bags is uneven, which has the risk of rupture and leakage.Once the refrigerant leaks, not only the surrounding environment and objects may be contaminated, but also potential threats to human health may be caused. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a self-supporting packaging bag that can keep cold, which is not only reasonable in structure, but also convenient and fast.

[0005] To solve the above technical problems, the technical scheme of the utility model is as follows: a self-supporting packaging bag that can keep cold, comprising an outer bag body, a drink bag is concentrically arranged in the outer bag body, the top of the drink bag is open and sealed by a sealing strip, water injection openings are left between the two ends of the sealing strip and the side wall of the drink bag for water injection, the outer side wall of the top of the drink bag is fixedly connected to the inner wall of the outer bag body, a refrigeration material is filled in the outer bag body, and the top of the outer bag body is bound and closed.

[0006] Further, a handle opening is formed in the closed top of the outer bag body.

[0007] Further, the refrigeration material is composed of carboxymethyl cellulose and water-absorbing resin.

[0008] Further, the side edge of the outer bag body is triangular, vertical creases are arranged in the middle of the two side walls of the outer bag body, and horizontal creases are arranged in the middle of the bottom of the outer bag body for folding.

[0009] Furthermore, the inner wall of the outer bag is provided with a heat-insulating and waterproof layer.

[0010] Furthermore, an easy-tear opening is provided near the top of the outer bag.

[0011] Furthermore, the bottom of the beverage bag is rounded.

[0012] Compared with existing technologies, this invention has the following advantages: While the beverage inside the bag is cooled, it avoids the dilution and impact on taste and flavor that occurs with ice cubes. The specific heat capacity of the refrigeration material is 3-4 times that of ice, featuring a low melting rate during thawing and excellent cold-keeping performance, providing better cold-keeping for beverages. It is clean and non-toxic, and does not cause water pollution during thawing, offering a better user experience. Furthermore, the packaging bag is reusable; when reused, there is no need to repeat the water-absorbing step, only refrigeration is required.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0014] Fig. 1 This is a schematic diagram of the structure of an embodiment of the present utility model;

[0015] Fig. 2 This is a side view of an embodiment of the present utility model.

[0016] In the picture: 1-outer bag body, 2-beverage bag, 3-sealing strip, 4-refrigeration material, 5-drawstring opening, 6-handle opening, 7-vertical crease, 8-horizontal crease, 9-easy tear opening, 10-water inlet. Detailed Implementation

[0017] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0018] like Figs. 1-2 As shown, a self-standing packaging bag that can keep cold includes an outer bag body 1, a beverage bag 2 concentrically arranged inside the outer bag body, the top of the beverage bag being open and sealed by a sealing strip 3, water inlets 10 for water injection being left between the two ends of the sealing strip and the side wall of the beverage bag, the top outer wall of the beverage bag being fixed to the inner wall of the outer bag body, the outer bag body being filled with a refrigeration material 4, and the top of the outer bag body being tied and closed.

[0019] In this embodiment of the utility model, a handle opening 6 is provided at the top closed part of the outer bag.

[0020] In this embodiment of the invention, the refrigeration material is composed of carboxymethyl cellulose and water-absorbing resin.

[0021] In the embodiment of the utility model, the outer bag body side is triangular, vertical folds 7 are arranged in the middle of the two side walls of the outer bag body, and horizontal folds 8 are arranged in the middle of the bottom of the outer bag body for folding.

[0022] In the embodiment of the utility model, the inner walls of the outer bag body are provided with heat preservation and waterproof layers.

[0023] In the embodiment of the utility model, the outer bag body is provided with a tearable opening 9 near the top.

[0024] In the embodiment of the utility model, the bottom of the beverage bag is arc-shaped.

[0025] The working principle of the embodiment of the utility model is as follows: the beverage bag is made of food-grade barrier material and is used for containing beverages. The outer bag body serves as a cold preservation layer to provide long-term cold preservation for the beverages in the beverage bag. The carboxymethyl cellulose and water absorbing resin are built-in and the beverage bag is flat when not in use, which is suitable for logistics transportation. The outer bag body is folded through the vertical folds and the horizontal folds to be stacked and stored.

[0026] To activate the ice bag, the ice bag needs to be soaked in water first, the tearable opening is torn, water is injected into the water inlet, the refrigerant absorbs water and expands, and then the ice bag is placed in the refrigerator for cold preservation and can be used. By opening the sealing strip and adding beverages, the cold preservation effect of the beverages can be achieved. The double protection of the sealing strip and the bundle opening avoids the ice bag from being broken due to extrusion during transportation, so that the ice bag can be used for commercial and household purposes.

[0027] The utility model is not limited to the above-mentioned best embodiment, and anyone can derive other various forms of self-supporting packaging bags that can be cold preserved under the inspiration of the utility model. Any equivalent changes and modifications made in the scope of the utility model application for patent shall be covered by the utility model.
