Abstract
A method for the production of a plastic container which includes an essentially planar base part and a detachable top part comprises placing a top part having a thin flange extending from an end face at an open end thereof on an essentially planar base part, vibrating the top part relative to the base part to melt the thin flange, and discontinuing the vibration before the thin flange has become completely molten. The resulting plastic container is both air- and liquid-proof, yet the top part is easily detachable from the base part.
