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. ...

Benefits of technology

[0014]One primary objective of the present invention is to provide a cold and hot pack capable of being plasticized, in which the interior of a bag member is disposed with particle-like supporters formed with pores and served as supporting members, so a user can freely squeeze the bag member for pushing and displacing the particle-like supporters, meanwhile the particle-like supporters and a fluid accommodated in the pores are able to be moved at the same time, thereby enabling the shape of the cold and hot pack to be adjusted so as to be matched with the human body shape.

[0015]Another objective of the present invention is to provide a cold and hot pack capable of being plasticized, in which particle-like supporters and a fluid accommodated in pores thereof being in a negative pressure status are forced and secured through being pressed by the atmospheric pressure thereby preventing sag.

[0016]For achieving aforesaid objectives, one technical solution of the present invention is to provide a cold and hot pack capable of being plasticized, which 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 the 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.

[0017]One another objective of the present invention is to provide a cold and hot pack capable of being plasticized, in which a bag member is formed with at least an opening allowing a user to fill in a fluid and easily control the volume of the fluid, thereby enabling the...

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 ap...
