Description

Biodegradable disposable toilet bowl cover

Technical Field

The utility model relates to the field of articles for daily use, in particular to a biodegradable disposable toilet bowl cover.

Background

The toilet bowl is widely applied to public places such as hospitals, hotels, public toilets and the like, and is one of household articles widely used in daily life of people. However, due to the fact that the toilet in public places is high in use frequency, disinfection and sterilization measures are not timely and the like, many bacteria, viruses, microorganisms and the like which cannot be seen by naked eyes exist on the toilet, and the human health is greatly and negatively affected. And is more likely to be a transmission path of viruses and infectious diseases. Therefore, in order to prevent people from contacting infectious viruses when using the toilet, it is necessary to design a disposable toilet cover. At present, the common disposable toilet bowl cover in the market is mainly made of non-woven fabrics or polyethylene films. The traditional non-woven fabric generally adopts polyester fiber which is taken as a main production raw material. The waste of the traditional non-woven fabrics and polyethylene films after use is difficult to recycle and is not degradable, and white garbage is easy to generate so as to pollute the ecological environment. Therefore, the novel biodegradable disposable toilet bowl cover is designed, and the ecological environment is not damaged while bacteria and viruses are isolated.

Most of the existing disposable toilet sleeves are made of polyester fibers, non-woven fabrics or polyethylene films made of polyester fibers, are not degradable, and are easy to pollute the ecological environment. In addition, the single-layer non-woven fabric structure has single performance and poor waterproof performance, and can not isolate bacteria, viruses and the like well. When the disposable closestool cover with the polyethylene film is used, adhesion with skin is easy to generate, slipping is easy to occur, and the user experience is poor.

The existing non-woven disposable toilet bowl cover is generally prepared by adopting a spunbonding method. Polyethylene film type disposable toilet covers are generally prepared by a film blowing process.

The traditional disposable toilet bowl cover has the following main defects:

1. the product is usually made of polyester fiber, polyester fiber or polyethylene film, and is nondegradable and incinerated to generate harmful gas.

2. The single-layer non-woven fabric has poor waterproof performance and can not effectively isolate bacteria, viruses, microorganisms and the like.

3. The single-layer non-woven fabric has lower structural strength and poorer tear resistance.

4. The polyethylene film toilet bowl cover is easy to adhere to skin when in use, and the user experience is poor.

5. Because the polyethylene film is soft in texture, slipping is easy to occur when the polyethylene film is used, and a good fixing effect cannot be achieved.
