Cloth-plastic hot-water bag and processing method

Abstract

The present invention relates to a cloth-plastic hot-water bag and its processing method. Said hot-water bag is composed of bag body, bag mouth and bag plug. The described bag body possesses internal layer, external layer and heat-insulating layer, the edge of said bag body has bonded strip. The described bag plug is formed from screw plug socket and screw plug cover, the external wall of said screw plug socket has a composite layer and said screw plug cover is equipped with a gasket seal.

Description

technical field [0001] The invention relates to a hot water bag, in particular to a cloth-plastic hot water bag and a processing method of the cloth-plastic hot water bag, which is mainly used for medical care and general life heating. Background technique [0002] When a certain part of the human body is injured or diseased, hot compress (or cold compress) is needed, and a hot water bottle is often used. On the other hand, in cold weather, people usually use hot water bags to warm their hands and other parts in their lives or work. However, the traditional hot water bottle is made of single-layer rubber material. First, the conduction is too fast, the thermal insulation performance is poor, and it overheats at the beginning. The second is that the rubber material has odor pollution, which can make people feel uncomfortable. The 3rd, fragile, short service life. Therefore, people have developed cloth-plastic hot water bag in recent years, but the pocket inner wall of exis...

AI Technical Summary

Problems solved by technology

However, the traditional hot water bottle is made of single-layer rubber material. First, the conduction is too fast, the thermal insulation performance is poor, and it is overheated at the beginning. It is often necessary to wrap it with a towel, but the cooling speed is also fast.

Second, the rubber material has odor pollution, which will make people feel uncomfortable

Third, it is easy to break and has a short service life

Therefore, people have developed cloth-plastic hot water bag in recent years, but the pocket inner wall of existing cloth-plastic hot water bag and plug seat are bonded by gluing, and some adopt thread or steel wire to fasten, and the shortcoming that it exists is not only cumbersome, but also sealed connection. Poor performance, leaks, short lifespan

In particular, the existing technology does not carry out the inflatable pressure test on the product, so the qualified rate is low and there are many waste products to be recycled.
