Cold and hot pack capable of being plasticized

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

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a cold and hot pack, especially to a cold and hot pack capable of being plasticized.[0003]2. Description of Related Art[0004]A cold and hot pack is commonly used in our daily lives, such as being used in a mattress, a cushion, a pillow or an eye cover.[0005]The conventional cold and hot pack can be categorized in two types, the first type is to have a bag member being filled with a fluid, and the second type is to have a bag member being filled with a fluid and installed with an inner lining thereby allowing a negative pressure status to be formed inside the bag member. Basically, the first type of the cold and hot pack is to have a fluid being filled in the cold and hot pack, and a thickening agent is added or the bag member is further divided into several independent partitioned members thereby capable of improving a disadvantage of the fluid sag due to being attracted by the gravity. ...

AI Technical Summary

Benefits of technology

The present invention provides a plasticizable cold and hot pack with particle-like supporters and a fluid accommodated in the pores of the supporters. The interior of the bag member is disposed with particle-like supporters formed with pores and served as supporting members, which allows the user to squeeze the bag member for pushing and displacing the particle-like supporters while the fluid accommodated in the pores is able to be moved at the same time. This enables the shape of the cold and hot pack to be adjusted so as to match the human body shape. The present invention also provides a negative pressure status for the particle-like supporters and the fluid, which prevents sag. The cold and hot pack can be easily filled with a fluid and is able to be controlled in a negative pressure status, thus providing an excellent cold compressing effect. The present invention also provides the advantage of easy storage and carriage around, and a weight reduction during transportation.

Problems solved by technology

Thus, when the first type of the cold and hot pack is used as a sitting or bedding pad, a shortage of causing unstable motion such as floating is generated.

In fact, for being applied as a cold and hot pack, the fluid is unable to be remained at the desired location thereby providing poor performance.

In addition, when being applied for cold compressing, the bag member would be expanded and unable to be matched with the shape of human body.

On the other hand, if a sponge is adopted as the inner lining for the second type of the cold and hot pack, the sponge can only provide a small supporting force when the bag member is being pressed, so the volume of the sponge is compressed and shrunk, and the fluid is discharged from the sponge thereby losing the negative pressure status and causing the fluid sag.

For improving the above-mentioned disadvantages, skilled people in the art have utilized a spacer fabric inner lining for replacing the sponge, but the spacer fabric inner lining still has following disadvantages:1. The spacer fabric inner lining is expensive, thereby unable to be applied in every cold and hot pack.2. The fabrication of the spacer fabric inner lining is not easy, and the general thickness is about 1 cm, so the space inside the bag member allowing the negative pressure to be generated is limited thereby unable to be filled with sufficient amount of fluid.3. When the spacer fabric inner lining is tailored, the fallen filaments are hard to be completely removed, so the process of filling fluid may be affected, if the filaments are adhered at the location where the sealing is taken place, the bag member is unable to be completely sealed.4. The spacer fabric inner lining is formed as a sheet-like member, the user cannot move or adjust the thickness according to his / her actual needs for allowing the cold and hot pack to be fully matched with the human body shape thereby unable to provide the excellent cold and hot compressing effect.5. The manufacturing of the cold and hot pack having the spacer fabric inner lining is difficult, because the air remained in the interior is hard to be discharged, the negative pressure status is difficult to be achieved.
