<p>[PROBLEMS]To provide a biodegradable resin bottle which has a deposited film formed on the inner surface of a wall of the bottle, which is effectively prevented from being thermally deformed during the formation of the film, and which has an excellent barrier property against both of oxygen and moisture when either of an oily content or an aqueous content is filled therein.[MEANS FOR SOLVING PROBLEMS]Disclosed is a biodegradable resin bottle which has a wall (1) comprising a biodegradable resin and also has a deposited film (3) formed on the inner surface of the wall (1) by a plasma CVD process. The deposited film (3) is composed of a first hydrocarbon-containing deposited layer (3a) arranged on the inner surface of the wall of the bottle and a second hydrocarbon-containing deposited layer (3b) formed on the deposited layer (3a). The first hydrocarbon-containing deposited layer (3a) has a polar group introduced therein. The second hydrocarbon-containing deposited layer (3b) has no polar group introduced therein, and has hydrocarbon-derived peaks respectively derived from CH, CHand CHappearing in a wavelength region ranging from 3200 to 2600 cmas measured by FT-IR method, in which the CHpeak ratio and the CHpeak ratio relative to the sum total of the peaks for CH, CHand CHis 35% or less and 40% or more, respectively, as calculated based on the hydrocarbon-derived peaks.</p> |
