And for example China announces No. 495384 patent cases (call in the following text and quote case as proof), it is a kind of composite material, its be can with environment that water contacts in be used for decomposing the one or more cmpd that is selected from the group that airborne oxides of nitrogen, ammonia and sulphur dioxide forms, this composite material comprises base material and superficial layer at least, this superficial layer is wetting ability and has the auto purification ability that this superficial layer comprises:

The irradiation of component i-be subjected to light can produce the nanoscale TiO2 photocatalyst of catalysis;

Component i i-is selected from by Al ₂O ₃, ZnO, SrO, BaO, MgO, CaO, Rb ₂O, Na ₂O, K ₂O and P ₂O ₅One or more metallic oxide among the group who is formed; And

Component i ii-is selected from by SiO ₂, ZrO ₂, GeO ₂And ThO ₂One or more metallic oxide among the group who is formed.

Comprehensive above-mentionedly quote the case characteristics as proof, but find that its room for improvement that has is as follows:

1, do not prevent that at the carrying liquid of flask the function that goes bad from improveing;

2, do not emphasize that all the flask that uses has effect, especially the polyester PET bottle of its coating object of protection.

3, can not promote ultraviolet ray or the high light absorption efficiency is made improvement at flask.

So this case contriver urgently thinks to be improved innovation, and after concentrating on studies through taking great pains to attain one's goal for many years, successfully this part flask is finished in research and development finally.

Summary of the invention

Purpose of the present invention promptly is to provide a kind of flask that carrying liquid prevents rotten function that has.

Of the present invention time a purpose is to provide a kind of flask that absorbs sunlight middle-ultraviolet lamp or visible light that promotes.

Another object of the present invention is to provide a kind of flask of tool protective film, can prevent the oxidized decomposition of plastic bottle producing stature matter.
