MANUFACTURING METHOD FOR ICE/HOT COMPRESS PRODUCT

Abstract

A manufacturing method for an ice/hot compress product includes the following steps: providing a polyester fiber cloth as an outer layer; adding a thermochromic material into the outer layer when the outer layer is dyed; and attaching an inner layer to an inner side of the outer layer to which the thermochromic material has been added to form a composite-layer material; manufacturing a container through the composite-layer material.

Claims

1. A manufacturing method for an ice/hot compress product, comprising: providing a polyester fiber cloth as an outer layer; adding a thermochromic material into the outer layer when the outer layer is dyed; and attaching an inner layer to an inner side of the outer layer, to which the thermochromic material has been added, to form a composite-layer material; manufacturing a container through the composite-layer material.

2. The manufacturing method as claimed in claim 1, wherein the inner layer is a thermoplastic polyurethane elastomer layer.

3. The manufacturing method as claimed in claim 1, wherein the inner layer is a polyvinyl chloride layer.

4. The manufacturing method as claimed in claim 1, wherein the thermochromic material is a mono thermochromic material.

5. The manufacturing method as claimed in claim 1, wherein the thermochromic material is a two-stage-indication thermochromic material.

6. The manufacturing method as claimed in claim 1, wherein the thermochromic material is a multi-stage-indication thermochromic material.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

[0021] Referring to FIG. 1, a manufacturing method of an ice/hot compress product of the invention includes the following steps:

providing a polyester fiber cloth as an outer layer 10;
adding a thermochromic material 11 into the outer layer 10 when the outer layer 10 is dyed; and
attaching an inner layer 12 to an inner sided of the outer layer 10 to which the thermochromic material 11 has been added to form a composite-layer material;
manufacturing a container 20 through the composite-layer material.

[0022] Referring to FIGS. 2 and 2A, a seat 21 is mounted to a top of the container 20 to form an entrance 22 (see FIG. 3) for filler. A cover 23 is fitted to the seat 21 to close or open the entrance 22 so as to seal the container 20 or open it.

[0023] The inner layer 12 can be made of various material according to the container 20 serving as an ice/hot bag or an ice/hot pack, such as thermoplastic urethane (TPU) or polyvinyl chloride (PVC). The material can prevent leakage of filler and facilitate the combination of the outer layer 10 and the inner layer 12.

[0024] In an embodiment, the thermochromic material 11 can be a mono thermochromic material which shows a color at a low temperature (FIG. 4), but shows no color at a high temperature (FIG. 3). For example, when the temperature of the filler in the container 20 drops to 25 C., the thermochromic material 11 begins to show a color, and the color saturation reaches 100% when the temperature drops to 22 C. In another embodiment, the thermochromic material 11 can also be a two-stage-indication thermochromic material which shows a color (for example green color) at a low temperature and shows the other color (for example red color) at a high temperature. In another embodiment, the thermochromic material 11 can also be a multi-stage-indication thermochromic material which shows a color (for example purple color) at a low temperature, shows another color at a medium temperature (for example light red color) and shows another color (for example red color) at a high temperature.

[0025] The invention provides an ice/hot compress product capable of indicating temperature change of the filler in the container 20. Since the thermochromic material 11 has been added to the outer layer 10 when the outer layer 10 is dyed, it simplified the manufacturing process for the thermochromic product.

[0026] While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
