<P>PROBLEM TO BE SOLVED: To innovate the shape of a PET bottle body and its cap's opening preventing ring so that the cap's opening preventing ring can easily be removed. <P>SOLUTION: Protrusions A, B, C, D of a shape of triangular prism are provided on the PET bottle body 1 and its cap's opening preventing ring 2, the protrusions A and B located on the PET bottle body 1 side while the protrusions C and D located on the cap's opening preventing ring 2 side, with the neighborhoods of their vertexes being in contact, whereas the space between A and C is made to be in contact when the cap is not opened, while the space between B and D is given with a gap of about 2 to 3 mm. The space between the protrusion C and D of the cap's opening preventing ring 2 is provided with perforation in a manner vertical to the cap's opening preventing ring 2. This structure allows the perforation of the cap's opening preventing ring 2 to be severed when the cap is opened, so that the cap's opening preventing ring 2 can easily be removed from the PET bottle body 1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
