The disclosed method may include bending, by an end-shaping tool, a portion of an end of a strap in a direction at least substantially perpendicular to a plane of the strap. The bending may include extending the portion of the end of the strap over a raised area of a first portion of the end-shaping tool and connecting a second portion of the end-shaping tool to the first portion. The connecting may include placing a recessed area of the second portion over the raised area of the first portion. The method may include debossing, by an end-setting tool dimensioned to accommodate the strap as bent by the end-shaping tool, the portion of the end of the strap at the bend. Various other methods, systems, and apparatus are also disclosed.

An assembly of fluid conduit parts is disclosed along with a method of assembling, a method of manufacturing and an apparatus for manufacturing the one of the fluid conduit parts. The assembly includes a blow molded part having a first portion. A second part includes a tapered section and a sealing flange extends from the first portion towards a central axis of the first portion at a distance, an end of the sealing flange defines an opening. The second part inserts into the opening and at least part of the tapered section is of a size larger than the opening. The sealing flange flexes upon insertion of the second part into the opening to define a contact surface between the tapered section and the sealing flange that extends around a perimeter of the tapered section where the sealing flange contacts the tapered section.

A blow molded container is provided. The container includes a neck including a sealing surface and a neck finish. The sealing surface defines at least one vent. In some embodiments, methods of manufacturing containers are disclosed.

A method for producing pipettes (110, 111, 112) is provided. The method includes extruding a polymer melt into at least one mold segment of a mold assembly (120) having a plurality of mold segments to form a parison (50) or preform, wherein the plurality of mold segments (122) comprise cavities (42) that are shaped to form pipettes when in communication with the cavity of an adjacent mold segment; forming at least two pipettes in the shape of the mold segment cavities by blow-molding or vacuum forming the parison or preform, each of the at least two pipettes having proximal and distal ends; heating the pipettes to form a locally heated portion of the at least two pipettes; and separating the pipettes by cutting the locally heated portion of the at least two pipettes with separation feature (64, 66, 194, 196).
