초록

This relates to the strengthening of the base of a blow molded plastic bottle and like container wherein the container base is of the type having generally hemispherical portions alternating circumferentially with projecting feet defining portions. It has been found that by roughening the surface of the base, particularly the lower central portion thereof, the base is greatly strengthened. The base is formed by blow molding in a blow mold base portion which has been roughened by shot peening.

대표
청구항

A blow molded plastic container for packaging products under pressure, said container having a base including generally hemispherical portions disposed in circumferential alternating relation with projecting feet defining portions, said base having a roughened external surface defining means for effecting dispersal of surface energy due to internal pressures.
