Provided is a double-walled container (1), which includes an outer layer body (2) and an inner layer body (3). A single adhesive strip (4) is disposed between the outer layer body (2) and the inner layer body (3) in a manner such that the adhesive strip (4) extends along a center axis (C). The outer layer body (2) is provided with a single ambient air introduction hole (2d). The outer layer body (2) includes an inner surface, which is configured by a separation surface (2f) and a pseudo-adhesive surface (2g). The separation surface (2f) faces the ambient air introduction hole (2d) and is separated from an outer surface of the inner layer body (3), and the pseudo-adhesive surface (2g) faces the separation surface (2f) and is separably adhered to the outer surface of the inner layer body (3).

A modular plastic pipe formation apparatus, wherein at least two components of the pipe formation apparatus are disposed with respect to at least one or more respective modules.

A vehicle running board includes opposing vertical walls extending along a length of a tubular structure and including a carbon-fiber component. Opposing horizontal walls extend between the opposing vertical walls and include a glass component. The opposing vertical and opposing horizontal walls form the tubular structure having a generally rectilinear cross section. A polymer outer covering extends over the opposing vertical and opposing horizontal walls.

The present disclosure in one aspect provides a sterile packaging container comprising a container body with a cross-sectional shape that is constant along the majority of the longitudinal axis, a cover and a closure assembly that inhibits the passage of microbial contaminants. The container is configured such that the interior of the container can be sterilized. The sterile packaging container described herein allows one to manufacture a sterile packaging tube exercising the smallest possible volume.

Techniques for forming a helical rubber hose are provided. Such techniques include modified crosshead extrusion techniques in which an elastomer is melted, fed into a crosshead assembly, and extruded on a helical mandrel fed through the crosshead assembly to form a hose. In techniques described herein, relative axial and rotational motion of the mandrel and a die plate at or on the outlet or output of the crosshead assembly are kinematically matched such that the distance of relative axial movement of the mandrel per one revolution equals one pitch of the mandrel.

A tube or a hose including a fluoroelastomer and a polytetrafluoroethylene, the tube or the hose being an extruded article. The polytetrafluoroethylene is dispersed in a state of single particles in the extruded article, or the polytetrafluoroethylene has a specific surface area of less than 8 m.sup.2/g. Also disclosed is an extruded laminate including a fluoroelastomer layer formed form the tube or hose and a polymer layer.

A web. The web includes an array of discrete polymeric tubes, wherein the cross-section of each polymeric tube has a non-circular shape; wherein adjacent polymeric tubes has a bond region; wherein polymeric tubes are hollow polymeric tubes; wherein adjacent polymeric tubes are connected at bond regions; and wherein the web is a continuous web.

A device for producing plastic containers (10) by means of a molding, filling and sealing process is disclosed, at least consisting of a molding device (16) having individual molding tools (18), which can be moved repeatedly relative to one another from an open receiving position into a molding sealing position, and an extrusion unit (12), which can be used to insert at least one extruded plastic hose (14) into the open receiving position of the molding tools (18), which is characterized in that a traversing unit (20) can be used to move the extrusion unit (12) in conjunction with each extruded plastic hose (14) in opposite directions with respect to the molding device (16), which is stationary in every position of the molding tools (18).
