Description

Technical Field

[0001] The invention relates to the technical field of ice bags, in particular to a novel self-absorbent water ice bag. Background Art

[0002] Ice packs are a novel freezing medium that does not contaminate water when thawed or melted. They can be reused for both hot and cold applications, and their effective cooling capacity is six times that of ice of the same volume, making them a viable alternative to dry ice and ice cubes. They have a wide range of applications, including medical treatments for fever reduction, inflammation and pain relief, cold compresses, sprains, hemostasis, suppuration, and skincare, among other adjunct therapies. They also facilitate the long-distance refrigerated transport of various biological cryogenic reagents, solder paste, poultry medicines, pharmaceuticals, plasma, vaccines, aquatic products, poultry, ornamental fish, and preserved foods for export. They are also used by athletes during training and competition to treat unexpected injuries such as bruises, sprains, and falls. In daily life, they can store cold and save electricity, maintaining low temperatures in the event of a power outage, preserving food, chilling beverages, and even travel.

[0003] The commonly used ice packs are of the following types: Figures 1-3 As shown, an existing ice bag is shown. The ice bag has a non-woven fabric surface 1 and a composite plastic layer 2. The edges of the non-woven fabric surface 1 and the composite plastic layer 2 are formed by hot pressing to form a heat-sealed edge 3. The interior is filled with water-absorbing resin particles 4. When in use, the ice bag is placed in water, and water penetrates into the interior from the non-woven fabric surface 1. The water comes into contact with the water-absorbing resin particles 4, and the water-absorbing resin particles 4 absorb water and expand.

[0004] like Figures 4-6 As shown, the existing ice bag 2 has a semi-composite plastic strip 5 hot-pressed onto one side of the non-woven fabric surface 1. When immersed in water, water enters the interior from the non-woven fabric surface 1, and the semi-composite plastic strip 5 occupies most of the area. When the ice bag 2 is filled with water and swells, the semi-composite plastic strip 5 protrudes. When adjacent ice bags 2 come into contact, the semi-composite plastic strip 5 is not easy to retain water due to its smooth surface, and therefore is not easy to freeze and stick together.

[0005] There is also an ice pack 3 (not shown) formed by hot pressing two composite plastic layers 2, and micropores are punched on the surface of the composite plastic layer 2 by laser.

[0006] The above-mentioned ice bag has the following problems: the non-woven fabric surface 1 of the ice bag is porous and is squeezed by water, and the middle part of the non-woven fabric surface 1 bulges outward. Since the non-woven fabric surface 1 is water-permeable, water will remain on the surface of the non-woven fabric surface 1. Therefore, when freezing, the non-woven fabric surfaces 1 of the ice bag are easily frozen and adhered to each other, and when forcibly pried apart, the non-woven fabric surface 1 is easily torn.

[0007] When the second ice pack is immersed in water, since the non-woven fabric surface 1 is located on one side of the semi-composite plastic strip 5, water inflow and exhaust from the inside to the outside are both through the non-woven fabric surface 1, resulting in reduced water inflow efficiency.

[0008] The ice bag three is full of water due to the relatively small number of micropores relative to the non-woven fabric surface 1. If the micropore diameter is increased, the water absorbing resin particles 4 are prone to seep out. SUMMARY

[0009] The present application aims to provide a new self-water-absorbing ice bag to solve the problems raised in the background art.

[0010] To achieve the above-mentioned purpose, the present application provides the following technical solution: a new self-water-absorbing ice bag, comprising:

[0011] An outer bag body and water-absorbing resin particles filled in the inner part of the outer bag body;

[0012] The outer bag body comprises a composite plastic layer and a water-permeable layer, and the edge of the water-permeable layer is heat-pressed with the edge of the composite plastic layer to form a heat-sealed edge one.

[0013] The water-permeable layer comprises a non-woven fabric surface and a semi-composite plastic strip arranged in the middle part of the non-woven fabric surface, and the connection part of the semi-composite plastic strip and the non-woven fabric surface is heat-pressed to form a heat-sealed edge two.

[0014] Preferably, the composite plastic layer is made of PE material.

[0015] Preferably, the number of non-woven fabric surfaces is set to one, and the semi-composite plastic strip is heat-pressed in the middle part of the non-woven fabric surface.

[0016] Preferably, the number of non-woven fabric surfaces is set to two, and the space between the two non-woven fabric surfaces is heat-pressed, the semi-composite plastic strip is located in the heat-pressed space, and the two sides of the semi-composite plastic strip are heat-pressed with the corresponding edges of the two non-woven fabric surfaces.

[0017] Preferably, the width between the heat-sealed edge one, the semi-composite plastic strip and the non-woven fabric surface is 2.8cm-3.2cm.

[0018] Preferably, the composite plastic layer and the semi-composite plastic strip are made of the same material.

[0019] Preferably, a grid water storage area or multiple grid water storage areas are formed between the composite plastic layer and the water-permeable layer. When multiple grid water storage areas are formed between the composite plastic layer and the water-permeable layer, multiple heat-sealed edges three are formed between the composite plastic layer and the water-permeable layer by heat pressing, and the area formed between the heat-sealed edges three is the multiple grid water storage area.

[0020] Preferably, the manufacturing steps of the new self-water-absorbing ice bag are as follows:

[0021] S1: Set the size of the composite plastic layer and the water-permeable layer, and cut the composite plastic layer;

[0022] S2: hot-press the non-woven fabric surface with both sides of the semi-composite plastic strip, and then cut the non-woven fabric surface and the semi-composite plastic strip as a whole according to the size, to form a water-permeable layer, the size of the water-permeable layer being the same as that of the composite plastic layer;

[0023] S3: adhere the composite plastic layer and the water-permeable layer, and hot-press the three edges between the composite plastic layer and the water-permeable layer first, to form an open ice bag, fill the water-absorbing resin particles at the opening of the ice bag, and then hot-press the opening of the ice bag.

[0024] Compared with the prior art, the present application has the following advantages:

[0025] In the present application, the semi-composite plastic strip is arranged in the middle of the water-permeable layer, and the non-woven fabric surfaces on both sides of the semi-composite plastic strip are used for water inlet and air exhaust, or water inlet and air exhaust are performed simultaneously from the non-woven fabric surfaces on both sides, so that the water inlet efficiency is improved, and the internal water-absorbing resin particles are prevented from seeping out.

[0026] When the ice bag is inflated by water, the semi-composite plastic strip is protruded, and the contact between the ice bags is mainly the contact of the protruded semi-composite plastic strips, which indicates that water is not easy to remain, and ice adhesion is not easy to occur.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] Embodiment one:

[0042] Please refer to Figures 7-11 The present application provides a technical solution: a new self-absorbing water ice bag, comprising:

[0043] The outer bag body and the water-absorbing resin particles 4 filled in the inner part of the outer bag body;

[0044] Among them, the outer bag body includes a composite plastic layer 2 and a water-permeable layer, the edge of the water-permeable layer and the edge of the composite plastic layer 2 are hot-pressed to form a heat sealing edge one 3, the water-permeable layer includes a non-woven fabric surface 1 and a semi-composite plastic strip 5 arranged in the middle part of the non-woven fabric surface 1, and the connection between the semi-composite plastic strip 5 and the non-woven fabric surface 1 is hot-pressed to form a heat sealing edge two 6.

[0045] The above analysis: in actual use, the ice bag is placed in water, so that one side of the non-woven fabric 1 is lower than the water surface, and the other side of the non-woven fabric 1 is higher than the water surface, so that the non-woven fabric 1 below the water surface can enter the water, and the other side of the non-woven fabric 1 is used to discharge air, so that air and water flow in one direction, and no obstruction occurs, and the overall water inlet efficiency is high. When enough water enters the ice bag, the ice bag is inflated as a whole, and since the semi-composite plastic strip 5 is located in the middle and protrudes the highest, the semi-composite plastic strips 5 of adjacent ice bags are most likely to approach each other. Due to the material properties of the semi-composite plastic strip 5, it is smooth and not easy to retain moisture, so it is not easy to freeze and stick between adjacent ice bags.

[0046] Example two:

[0047] Please refer to Figures 7-11 , the application based on example one provides a technical solution: the composite plastic layer 2 is made of PE material, and the composite plastic layer 2 and the semi-composite plastic strip 5 are made of the same material.

[0048] The above analysis: PE material is smooth and has good toughness, and is not easy to get wet.

[0049] Example three:

[0050] Please refer to Figures 7-11 , the application based on example one provides a technical solution: the connection form of the non-woven fabric 1 and the semi-composite plastic strip 5 includes the following two kinds:

[0051] The first kind: as shown in Figure 10 , the number of non-woven fabric 1 is set to one, and the semi-composite plastic strip 5 is hot-pressed in the middle of the non-woven fabric 1.

[0052] The second kind: as shown in Figure 11 , the number of non-woven fabric 1 is set to two, and the two non-woven fabric 1 is a hot-pressing space 7, the semi-composite plastic strip 5 is located in the hot-pressing space 7, and the two sides of the semi-composite plastic strip 5 are hot-pressed and connected with the corresponding edges of the two non-woven fabric 1.

[0053] The above analysis: the above two connection forms of the non-woven fabric 1 and the semi-composite plastic strip 5 can meet the requirements, the second kind is relatively material-saving, and the first kind is relatively simple in process implementation.

[0054] Example four:

[0055] Please refer to Figures 7-11 , the application based on example three provides a technical solution: the width between the heat-sealed edge one 3 and the semi-composite plastic strip 5 of the non-woven fabric 1 is 2.8cm-3.2cm.

[0056] The analysis of the above content: the width between the heat-sealed edge one 3 and the half-composite plastic strip 5 on the non-woven fabric surface 1 is 3 cm, which is the best, which can ensure the water absorption efficiency and avoid the adhesion effect.

[0057] Example five:

[0058] Please refer to Figures 7-11 The application based on example one provides a technical solution: the composite plastic layer 2 and the water-permeable layer form a grid water storage area or a multi-grid water storage area, when the composite plastic layer 2 and the water-permeable layer form a multi-grid water storage area, the composite plastic layer 2 and the water-permeable layer form a plurality of horizontal and vertical intersecting heat-sealed edges three through hot pressing, and the area formed between the heat-sealed edges three is a multi-grid water storage area.

[0059] The analysis of the above content: when the ice bag is large as a whole, in order to make the water absorption resin particles 4 disperse uniformly, the inside of the ice bag is made into a plurality of small grids (water storage areas), so that the water absorption resin particles 4 can be dispersed in the plurality of small grids, and when absorbing water, the plurality of small grids absorb water respectively, and the small grids are isolated by the heat-sealed edges three, and are not easy to be affected.

[0062] S1: set the size of the composite plastic layer 2 and the water-permeable layer, and cut the composite plastic layer 2;

[0063] S2: hot-press the non-woven fabric surface 1 and the two sides of the half-composite plastic strip 5, and then cut the non-woven fabric surface 1 and the half-composite plastic strip 5 as a whole according to the size, to form a water-permeable layer, the size of the water-permeable layer is the same as that of the composite plastic layer 2;
