Abstract

PURPOSE:To obtain a biologically decomposing and disposable vessel, which is inexpensive, highly water-proof, and also decomposed in a short term by microbes due to a fast biologically decomposing speed, even if it is disposed without any treatment after use. CONSTITUTION:A biologically decomposing vessel body 10 made of a material in a biologically decomposing range, which is something like multi-saccharide such as starch-cellulose or the like, protein like gelatin, or its saccharide, all chemically treated, is coated with a biologically decomposing hydrophobic thin film 20 made of polycaprolactom or so at the surface thereof.

Reference numeral 10 is a biodegradable container body comprising a natural polysaccharide or protein, or a substance obtained by chemically modifying the polysaccharide or protein within the range of biodegradability. Is a hydrophobic biodegradable plastic thin film that covers the surface of the biodegradable container body 10. Examples of the natural polysaccharides used in the present invention include simple substances such as starch, cellulose, agarose and carrageenan, and examples of proteins include gelatin. Alternatively, a mixture of polysaccharide and protein may be used. Further, the foam of the above substance promotes the biodegradability rate, and is more preferable as the biodegradable raw material of the biodegradable container body 10 of the present invention. Examples of the hydrophobic biodegradable plastics include polycaprolactone, polyglycolide, poly (3-hydroxybutyrate), poly (3-hydroxybutyrate-co-3 hydroxyvalerate) and the like.
