The purpose of the present invention is to provide a molded article and a manufacturing method for a molded article by which it is possible to mitigate deformation of an opening. The present invention provides a molded article comprising a cylindrical base and an opening provided in the base, wherein a rib is provided adjacent to the opening. The present invention provides a manufacturing method for a molded article that includes a molded body formation step for forming a molded body having a cylindrical portion provided at one end thereof with an occlusion by molding a melted resin, and a cut-off step for cutting off the occlusion by cutting the cylindrical portion, wherein in the cut-off step, the cutting is performed in a state where a side wall of the cylindrical portion is warped in-plane by an external force.

A polymeric stent has an inner surface with an inner diameter that tapers continuously in size. A method for manufacturing a stent includes blow molding a polymeric tube within a mold having a tapered, cylindrical cavity such that the polymeric tube attains a corresponding tapered shape. The tapered tube is used as a substrate from which a laser cuts interconnecting stent struts.

Method of making a blow-molded plastic container comprises forming a hollow blow-molded article comprising a main body portion defining an interior space, a finish portion defining a mouth in fluid communication with the interior space, the finish portion having a substantially cylindrical circumferential wall of generally uniform thickness surrounding the mouth, the circumferential wall having an upper edge with a perimeter flange and a pair of tabs projecting radially inward from the circumferential wall, the pair of tabs defining a spout therebetween, and a moil portion extending from the perimeter flange in a direction opposite the main body portion. Method further includes inflating the plastic material within the mold cavity to form the hollow blow-molded article and removing the moil portion from the perimeter flange. Blow-molded plastic container having a finish portion with directional pour spout and blow-molded article comprising container and moil portion also disclosed.

A method for producing a tube arrangement (1) for the transport of tempering medium, in which base body sections (6, 7) are provided, which have congruently configured separating surfaces (8), wherein at least one functional element (3) on at least one base body section (6, 7) is arranged in such a way that it can be in contact with the tempering medium, whereafter the base body sections (6, 7) are joined along the separating surface (8) and bonded to one another to form the tube arrangement (1).

The invention relates to a plastic container which is stretch blow-molded from a preform and which comprises a container body having a container neck attached thereto, on which container neck there is provided an outlet opening, wherein the container body has a second opening closed by a weld seam. The container is made from a copolyester. The wall of the stretched container body has a stretching ratio relative to the wall of the unstretched container neck in the region of the at least one weld seam of more than 6:1. After the welding, the stretched container body has a density increase relative to the unstretched container neck in the region of the at least one weld seam of less than 0.06 g/cm.sup.3.

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.

Apparatus for forming hollow containers (110), suitable to contain in particular one or more liquid or semi-liquid food products, starting from parisons (F) made of thermoplastic material. The apparatus comprises a matrix (11) defined by a pair of molds (12) cooperating with each other to define a cavity (13) shaped like the container (110) to be formed, and to define a support channel (14), configured to define an additional portion (112) of said container (110). The apparatus also comprises a forming punch (17), operatively mobile through said support channel (14) to enter into/exit from said cavity (13) so as to thrust and blow one of said parisons (F) against the walls of said cavity (13) to form at least said container (110).
