摘要:
A blow molded plastic container (40) including a supporting member (50) in the hollow space of the container extending completely across the hollow space and integral with the inside wall face of the body portion of the container at two spaced locations thereof to support the inside wall face. The body portion defines regions that comprise at least two adjoining lobes (60) which form a handgrip, at least one of said lobes including segments (53) deformed under internal pressure into the configuration (55) of said handgrip.
摘要:
A plastic preform (10) for forming blow molded containers (19) including at least one internal wall member (20) separately formed from the molded plastic article and extending completely across the hollow space therein, wherein the internal wall member has edge portions (22) which engage the body portion (24) and are joined thereto. Also discloses the blow molded plastic container (19) and method for forming preform (10) and container (19).
摘要:
A blow molded plastic container including at least one internal supporting member (50,50A,50B,83,84,85) integral with the inside wall face of the body portion to support same. In one embodiment, the body portion defines lobes (60,60A',60A'',60B) connected together by depressions (61,61A,61B) which define a handgrip, wherein the depressions are supported by the internal supporting member. In another embodiment, an axially, inwardly directed part (82) is supported by the supporting member.
摘要:
The process selectively crystallizes a molecularly oriented thermoplastic container (20) composed of portions thereof (23,24,25,26) with different degrees of orientation. Portions of the container (24,25) are heat treated at temperatures suitable to crystallize said portions according to the degrees of orientation thereof wherein the heat treatment takes place in a heating environment on an unconfined container. The selectively crystallized container is then sized in a finishing means.
