Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary products, and in particular to a flexible granular ice pack. Background Technology

[0002] Ice packs are a commonly used cold compress product. Applying ice packs to inflamed and swollen areas can reduce pain. However, current ice packs are solid blocks after freezing. Because ice packs cannot adapt to twisting during use, if the user's inflamed and swollen area (such as the ankle) is not flat, the current ice pack cannot fully contact the inflamed and swollen area, resulting in poor cold compress effects. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a flexible granular ice pack. The small frozen granules inside can adapt and flow, ensuring that all points on the inflamed and swollen area can fully contact the ice pack, thus ensuring a good cooling effect.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A flexible granular ice pack includes an inner flexible sheet and an outer flexible sheet; the inner flexible sheets are joined together to form a flexible inner hollow sphere, the cavity of the inner hollow sphere is filled with liquid, the diameter of the inner hollow sphere is 0.5 cm to 1.5 cm, the outer flexible sheets are joined together to form a flexible outer bag, there are multiple inner hollow spheres, and all the inner hollow spheres are filled in the outer bag.

[0006] In this type of flexible granular ice pack, an outer flexible sheet is used to make the outer bag body, and an inner flexible sheet is used to make the inner bag body. The inner bag body is filled with liquid, which can freeze at low temperatures. The liquid includes, but is not limited to, a saturated sodium chloride solution, an alcohol solution, or a resin. It freezes in a low-temperature environment (such as a freezer compartment) and thaws during use.

[0007] The method of using this type of flexible granular ice pack is as follows: First, place the entire ice pack in the freezer compartment of the refrigerator to freeze the liquid. Then, when you need to apply a cold compress, place it on the desired location. Because there are several independent small frozen granules inside the outer bag, these small frozen granules can move within the outer bag. When the outer bag is applied to the user's inflamed and swollen area, the small frozen granules inside the outer bag can move adaptively, ensuring that all points of the inflamed and swollen area can fully contact the ice pack, ensuring a good cold compress effect.

[0008] In summary, the small frozen particles inside this type of ice pack can adapt and flow, ensuring that all points on the inflamed and swollen area can fully contact the ice pack, thus ensuring a good cooling effect.

[0009] Optionally, the inner flexible sheet includes an antifreeze PE film, an alumina-coated PET film, and dry-laid paper. The antifreeze PE film and the dry-laid paper are located on opposite sides of the alumina-coated PET film. The antifreeze PE film is located on the inner wall of the inner cavity sphere, and the dry-laid paper is located on the outer wall of the inner cavity sphere.

[0010] The entire inner flexible sheet is composed of an antifreeze PE film, an alumina-coated PET film, and dry-laid paper. The antifreeze PE film serves as the inner wall, in contact with the liquid, while the dry-laid paper acts as the outer wall. The alumina-coated PET film provides excellent barrier properties, reducing liquid loss and corrosion. The antifreeze PE film, as the innermost layer, ensures the entire inner sheet has good expansion adaptability, while the dry-laid paper, with its absorbent properties, can absorb condensation generated during the initial freezing process, preventing the individual inner cavity spheres from freezing together and clumping.

[0011] Optionally, the thickness of the antifreeze PE film is 50 micrometers, the thickness of the alumina-coated PET film is 15 micrometers, and the thickness of the dry-laid paper is 80 micrometers.

[0012] Optionally, an adhesive layer is also included, which is disposed between the antifreeze PE film and the alumina-coated PET film, and the adhesive layer has a thickness of 2 micrometers.

[0013] Optionally, it also includes a coating resin layer disposed between the alumina-coated PET film and the dry-laid paper, the coating resin layer having a thickness of 15 micrometers.

[0014] The specific coating resin layer includes, but is not limited to, PE coating resin.

[0015] Optionally, the outer flexible sheet includes an OPP film.

[0016] The external flexible sheet can be, but is not limited to, an OPP film.

[0017] Optionally, the inner hollow sphere occupies 70% to 80% of the volume of the outer bag.

[0018] Optionally, the hollow sphere is spherical.

[0019] The beneficial effects of this invention are: the small frozen particles inside can adapt to flow, ensuring that all points of the inflamed and swollen area can fully contact the ice pack, thus ensuring a good cold compress effect. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0027] As attached Figure 1 and appendix Figure 2As shown, a flexible granular ice pack includes an inner flexible sheet and an outer flexible sheet; the inner flexible sheets are joined together to form a flexible inner hollow sphere 1, the cavity of the inner hollow sphere 1 is filled with liquid 10, the diameter of the inner hollow sphere is 0.5 cm to 1.5 cm, the outer flexible sheets are joined together to form a flexible outer bag 2, there are multiple inner hollow spheres, and all the inner hollow spheres are filled in the outer bag 2.

[0028] In this type of flexible granular ice pack, an outer bag body 2 is made of an outer flexible sheet, and an inner bag body is made of an inner flexible sheet. The inner bag body is filled with liquid 10. Liquid 10 can freeze at low temperatures. Liquid 10 includes, but is not limited to, a saturated sodium chloride solution, an alcohol solution, or a resin. It freezes in a low-temperature environment (such as a freezer compartment) and thaws during use.

[0029] The method of using this flexible granular ice pack is as follows: First, place the entire ice pack in the freezer compartment of the refrigerator to freeze the liquid 10. Then, when a cold compress is needed, place it on the desired location. Because several independent small frozen particles are placed inside the outer bag 2, these small frozen particles can flow within the outer bag 2. When the outer bag 2 is applied to the user's inflamed and swollen area, the small frozen particles inside the outer bag 2 can adapt and flow, ensuring that all points of the inflamed and swollen area can fully contact the ice pack, ensuring a good cold compress effect.

[0030] In summary, the small frozen particles inside this type of ice pack can adapt to flow, ensuring that all points on the inflamed and swollen area can fully contact the ice pack, thus ensuring a good cooling effect.

[0031] Combined with appendix Figure 2 In this case, the hollow sphere can be formed by thermally bonding two flexible inner sheets together.

[0032] As attached Figure 1 and appendix Figure 2 As shown, the inner flexible sheet includes an antifreeze PE film 11, an alumina-coated PET film 13, and a dry paper 15. The antifreeze PE film 11 and the dry paper 15 are located on both sides of the alumina-coated PET film 13, respectively. The antifreeze PE film 11 is located on the inner wall of the inner cavity sphere, and the dry paper 15 is located on the outer wall of the inner cavity sphere.

[0033] The entire inner flexible sheet is composed of an antifreeze PE film 11, an alumina-coated PET film 13, and dry-laid paper 15. The antifreeze PE film 11 serves as the inner wall, contacting the liquid 10, while the dry-laid paper 15 serves as the outer wall. Due to the excellent barrier properties of the alumina-coated PET film 13, the leakage and corrosion of the liquid 10 are reduced. The antifreeze PE film 11, as the innermost layer, ensures good expansion adaptability of the entire inner sheet, while the dry-laid paper 15 has a certain degree of water absorption, absorbing condensate generated during the initial freezing process. This prevents the individual inner cavities from freezing together and clumping. Furthermore, the inner flexible sheet in this ice pack has good flexibility and self-adaptive deformation capabilities, allowing for adaptive deformation during freezing.

[0034] As attached Figure 1 and appendix Figure 2 As shown, the thickness of the antifreeze PE film 11 is 50 micrometers, the thickness of the alumina-coated PET film 13 is 15 micrometers, and the thickness of the dry paper 15 is 80 micrometers.

[0039] As attached Figure 1 and appendix Figure 2 As shown, the outer flexible sheet includes an OPP film.

[0040] The external flexible sheet can be, but is not limited to, an OPP film.

[0041] As attached Figure 1 and appendix Figure 2 As shown, the inner hollow sphere occupies 70%~80% of the volume of the outer bag 2.

[0042] As attached Figure 1 and appendix Figure 2 As shown, the hollow sphere inside is spherical.

[0043] The above-described embodiments only illustrate some aspects of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
