Abstract
A blow mold for producing bottles or similar hollow containers from parisons of synthetic plastic material comprises two mirror-symmetrically arranged blow mold halves movable toward and away from each other between a closed and an open position. Each of the mold halves includes an outer mold part and an inner mold part guided for independent movement relative to the outer mold part in an endless inner face of the latter, the inner mold part having a concave end face which forms together with an adjacent portion of said inner face of the corresponding outer mold part in the closed position of the mold half of the mold cavity for forming a bottle. Each of the concave end faces of the inner mold part may also be provided with an island-shaped sharp edged projection aligned with and engaging in the closed position of the mold a corresponding projection on the inner mold part of the other mold half for forming a grip opening in the bottle.
