Plastic temperature-adjustable pack

Abstract

A cold and hot pack capable of being plasticized comprises: a bag member made of an impermeable soft sealing material; plural particle-like supporters disposed in the bag member, each of the particle-like supporters is formed with at least a pore; and a fluid filled and accommodated in the pores of the particle-like supporters, and a negative pressure status is formed inside bag member, thereby enabling the particle-like supporters and the fluid to be pressed and secured by the atmospheric pressure so as to prevent sag. The present invention is able to be applied in various fields such as a cold and hot pack, a sitting pad, a water bed, an anti-bedsore mattress and a temperature keeping pack, and provides better functions and quality comparing to prior art.

Description

technical field [0001] The invention relates to a hot and cold compress bag, in particular to a shapeable hot and cold compress bag. Background technique [0002] The occasions where people use hot and cold compress bags can often be seen, and the more common ones, such as mattresses, cushions, pillows, chair cushions, eye masks, etc., can be described as dazzling and varied. [0003] Known hot and cold compress bags are mainly divided into two categories, one is to fill the bag with liquid, and the other is to fill the bag with liquid and add a block lining to make the bag in a negative pressure state. Basically, the first type of hot and cold compress bag is filled with liquid in the hot and cold compress bag, and a thickener is added or the bag body is further divided into multiple small independent separators to improve the natural vertical flow of the liquid due to gravity attraction. shortcoming. The second type of cold and hot compress bag is in a negative pressure ...

AI Technical Summary

Problems solved by technology

[0005] 1. The three-dimensional fabric lining is expensive and cannot be commonly used in hot and cold compress bags

[0006] 2. The three-dimensional fabric lining is not easy to weave, and the general thickness is about 1cm, so that the negative pressure space inside the bag is limited, and it is impossible to fill enough liquid

[0007] 3. After the three-dimensional fabric lining is cut, it is difficult to remove the segmented monofilaments that fall off, causing troubles when filling the liquid later, and even sticking to the sealing position of the bag body, causing the bag body to be unable to be completely sealed

[0008] 4. The three-dimensional fabric lining is a sheet shape, which cannot allow users to move or adjust the thickness according to their needs, so that it can truly fit the body shape of the human body to achieve the best cold and hot compress effect

[0009] 5. The production of hot and cold compress bags lined with three-dimensional fabric is very difficult, because the air resident inside is difficult to discharge and it is not easy to achieve a negative pressure state

[0010] As shown in Taiwan Patent Announcement No. 585054 and No. I293601 invention patent (corresponding to U.S. No. 6,622,781 invention patent) applied for by the applicant of the present invention, a sheet of three-dimensional fabric (spacer fabric) is installed in the bag body, and the inside of the bag body Negative pressure is formed to use atmospheric pressure to press the liquid in the internal space of the three-dimensional fabric, so that the liquid will not flow vertically; however, because the thickness of the three-dimensional fabric is mostly below 1cm and the cost is high, it is impossible to adjust the thickness of different parts of the bag in order to fit in Human body shape, making hot and cold compresses more efficient
