The operating fluid container (10) here has the following features: the operating fluid container (10) has a container opening (12) which is arranged in a container upper shell (11) and is edged by a surround (13); the operating fluid container (10) comprises a tubular stiffening element (20) arranged in the operating fluid container (10); on the end, the stiffening element (20) has a circumferential connecting edge (21) in contact with the container upper shell (11); in a plan view onto the container upper shell (11), the container opening (12) is surrounded by the connecting edge (21); the stiffening element (20) is integrally connected to a container lower shell (14) and by means of the connecting edge (21) to the container upper shell (11); and the stiffening element (20) counteracts deformation caused by the internal pressure of the operating fluid container (10).

A component for a plastic tank for a motor vehicle, said component being suitable for being inserted into a parison during a manufacture of the plastic tank for the motor vehicle. The component has at least one dimension, in at least one plane perpendicular to a direction of extrusion of the parison, which is substantially equal to or greater than a minimum distance between two opposing points located on a solid inner wall of the parison in said at least one perpendicular plane. The component includes a frame containing a first deflection means including at least one surface suitable for coming into contact with and guiding a travel of the parison when the component is inserted into the parison.

A hollow body forming mold includes left and right half molds, a bottom of the left half mold is provided with a left avoidance slot, a bottom of the right half mold is provided with a right avoidance slot, a left bottom slider is disposed in the left avoidance slot, a right bottom slider is disposed in the right avoidance slot, and the left and right bottom sliders constitute a group of sliders. The mold design resolves a difficult problem that a fabrication hole exists during forming of a hollow body with a built-in component by using an existing conventional process. The hollow body forming method has the advantages of a short forming period, the high production efficiency, good combination between a built-in component and an inner wall of an fuel tank, and the high location stability.

A hollow container producing device for producing a hollow container using a pair of parison sheets is provided. The hollow container producing device includes a pair of molds; an intermediate frame to be clamped to the pair of molds; and a transport unit that carries the intermediate frame and a pair of parison sheets to a position between the pair of molds, with the pair of parison sheets being respectively held on opposite sides of the intermediate frame.

The present disclosure provides a container and a process for producing the container. In an embodiment, the process includes placing a sleeve bag on valve assembly (SBoV) in a blow mold apparatus. The blow mold apparatus has two opposing and movable molds. The SBoV has a valve seat. The process includes extending a parison of flowable polymeric material around the SBoV and between the opposing molds. The process includes moving the opposing molds to a closed position and pressing an upstream portion of the parison against the valve seat. The process includes blow molding a downstream portion of the parison into a container-shape within the closed mold. The process includes forming a container with the valve seat melt bonded to a neck portion of the container.

In at least some implementations, a blow molding apparatus provides that portions of the parison are engaged by one or more clamping devices disposed on or adjacent to the blow mold parts, and that the blow mold is opened whereby the parison is torn apart between the clamping devices, into two or more pieces of the parison. In other implementations, the clamping devices may be moved relative to the blow mold to tear the parison, or the parison may be torn by a combined movement of the blow mold parts and clamping devices.

A process of manual, semi-automatic and fully-automated integration of discrete components into a container that results in fast, reliable, cost-effective, and scalable production of composite containers is disclosed. The process can be embodied in manufacturing equipment that has a series of stations and may be called an assembly device. The equipment can produce containers, tubs, canisters, cartridges, etc. which are easily separated into different bio-degradable or compostable parts. Other container types are possible and are contemplated.

The invention relates to a method for producing a container from thermoplastic material having a connection element (5) passing through the wall thereof. The method comprises making available at least one plate-shaped or shell-shaped or tube-shaped preform (3) made of plasticized thermoplastic material, introducing the preform (3) into a multipart molding tool (1) having cavities defining at least one molding recess, molding and final shaping of the preform (3) within the molding tool (1) using differential pressure, piercing of the still warm-plastic preform (3) from the tool side by means of a mandrel (9) in order to produce an opening (6) in the preform (3), insertion from the molding recess side of a connection element (5) into the opening (6) produced by the mandrel (9), and connection of the connection element (5) to the preform (3).

Device 5 for connecting a gas line 6 to a bag-in-container type of container 3, comprising a first 61 and a second part 62, movably connected to said first part 61, wherein one of the first or second part 61, 62 comprises a coupling opening 60 with coupling elements 67 for connecting the device 5 to a part of a bag-in-container type container 3 extending inside coupling opening 60. The connecting device 5 comprises a connecting element 70, movable between an extended position wherein the connecting element 70 extends partly inside coupling opening 60 and a retracted position in which the connecting element 70 extends less or not into coupling opening 60, the connecting device 5 further comprising a mechanism 72 for moving the connecting element 70 between the extended and the retracted position by relative movement of first and second parts 61, 62.

The invention relates to a method for the production of a bladder accumulator (10) which separates two media chambers (16, 18) from one another in a storage housing (12) by means of a bladder body (14), comprising at least the following production steps:extruding a plastic tube over the bladder body (14);shaping the plastic tube with the integrated bladder body (14) in a molding tool that corresponds to a predeterminable plastic core container (20), andwinding at least one plastic fiber from the outside on the plastic core container (20) for the purpose of creating the storage housing (12).
