摘要:
A polyester container obtained by stretch-forming a preform of a thermoplastic polyester resin formed by injection forming wherein the central portion of the bottom wall is the remaining part of the gate at the time of injection forming, and is formed relatively thicker than the bottom wall surrounding the central portion, and the central portion of the bottom wall is substantially amorphous, and the bottom wall surrounding the central portion is oriented and crystallized. The container exhibits excellent heat resistance and shock resistance despite a thick portion that is the remaining portion of the injection gate is formed at the center of the bottom portion.
摘要:
A polyester container furnished with a flange part having mechanical strength, transparency, and heat resistance through orientational crystallization, which polyester container exhibits low-temperature heat sealability, is provided by forming a projecting portion at an upper surface of the crystallized flange part, the projecting portion at at least a heat-sealing-face constituting region rendered amorphous or of low crystallinity. Further, in order to suppress the unevenness of the strength of sealing with a cover member and stably attain the high sealability, the projecting portion is deformed at the time of heat sealing with the cover member so as to form a resin piece protruding toward the interior of the container while being substantially appressed against the upper surface of an opening rim part. The formed resin piece couples with a sealant layer of the cover member.

摘要:
In a method for manufacturing a thermoplastic resin vessel, in which a cup-shaped vessel is thermally formed from a thermoplastic resin sheet by a plug, the method including the steps of: pre-forming a portion of the thermoplastic resin sheet corresponding to an orifice portion or a flange portion of the cup-shaped vessel; and clamping the pre-formed portion of the thermoplastic resin sheet to accomplish the forming. According to the manufacturing method, thickening of a vessel bottom part and warpage of the flange portion can be improved.

摘要:
A diagnostic agent for angiopathic diseases containing a monoclonal antibody against human smooth muscle myosin or active fragments of the antibody labeled with a radioactive isotope; a kit thereof; and a method of diagnostic imaging for angiopathic diseases by using the same. The invention permits the diagnostic imaging of angiopathic diseases such as dissecting aortic aneurysm and angiitis and the specification of the region affected by these diseases.
