A blow mold system including a mold body and a base portion. The mold body includes a central bore extending from a first end of the mold body to a second end of the mold body along a longitudinal axis. The first end is configured to receive a mold preform. The base portion includes a recess, and the base portion is arranged at the second end of the mold body such that the central bore and recess define a blow mold cavity in which a container may be formed from the mold preform. In embodiments, the blow mold system has at least two interchangeable base portions that allow for containers with differently-sized or differently-shaped necks to be formed.

The method for manufacturing a container having a substantially stiff outer container and a readily deformable inner bag of thermoplastic plastic materials which do not form a weld connection with one another, with a container opening and holes in the outer container, wherein the method includes forming holes in the wall of the outer container at diametrically opposed positions, which lie on the intersection line of a plane defined by the base seam and the longitudinal axis of the container with the container wall and that a pin-shaped tool forces the inner bag through the holes by a predetermined distance from the wall of the outer container and thereby detaches it from the wall, whereafter a pressure medium is introduced through the holes into the gap between the inner bag and the outer container, which detaches the inner bag from the wall of the outer container.

Provided is a manufacturing method for a double container that allows easy manufacturing with a molding device not significantly different from conventional devices and that can, at a lower cost than the processing cost of conventional technology, very easily and reliably form, in a comparatively rigid outer container and in a double container that allows, inside the outer container, capacity to be varied with respect to the amount of content, an opening for allowing external air to enter. When a pair of partial molds are brought near each other in order to form a split mold, at least part of the mating faces of the pair of partial molds forms a projection by sandwiching a small outer diameter portion of a parison, a gap that passes between the double container is created by cutting off the projection, and the gap is opened and expanded by screwing on a cap.

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 method of manufacturing a sole structure includes providing a plate within a cavity of a mold. The plate includes a base and a rib, and the base includes a first surface and a second surface. The first surface faces the upper, the second surface faces away from the first surface, and the rib projects from the second surface of the base. Moreover, the method includes providing a preform bladder member within the cavity of the mold, wherein the preform bladder member including a first member and a second member. The method additionally includes forming a bladder from the first and second members using the mold. Also, the method includes attaching the first member to the plate using the mold. Attaching the first member to the plate includes shaping the first member according to surfaces of the rib.

A blow-molding method for forming a squeezable or tubular plastic container is provided. The method includes molding a preform having a sidewall, an interior cavity, an open end, a closed end, and a neck adjacent the closed end of the preform. The neck of the preform has an engagement structure. The method includes providing a blow mold system including a blow mold cavity. The method includes placing at least a portion of the preform into the blow mold cavity, and blow molding a one-piece container body from the preform by inflating the preform within the blow mold cavity. The container body has an open end, a closed end and a neck adjacent to the closed end. Wherein the open end of the container body is formed from the open end of the preform, and the closed end of the container body is formed from the closed end of the preform. The method includes creating a dispensing opening through the closed end of the container body.
