A method for producing a plastic container provided with at least one insert part by blow molding, which includes introducing a tubular preform, which is open at least at one end, into a blow molding tool; inserting the insert part into the open end of the preform together with a protective device, which prevents the insert part from adhering to the inner surface of the preform during the inserting operation; pulling out the protective device from the preform; closing the blow molding tool; and carrying out a blow molding operation. Also disclosed is an apparatus suitable for performing this method.

A blow-molded plastic structure has a hollow interior portion formed during a blow-molding process, and includes first and second outer portions that are spaced apart from each other, with the hollow interior portion disposed there between. The structure includes a pattern of structural stiffening features that are integrally formed in the second outer portion. The pattern of structural stiffening features includes a plurality of tripodal depressions disposed in rows and columns and a plurality of convex regions disposed in rows and columns between the plurality of tripodal depressions. Each convex region has a maximum height between the first and second outer portions. Each of the tripodal depressions extends into the hollow interior portion, includes three indentations disposed adjacent the first outer portion, and includes an island spaced away from the first outer portion. The island has three sides, each of which is disposed adjacent one of the three indentations.

A tank that includes a tank wall composed of a plastic material, and at least one reinforcing profile member configured to minimize deformation of the plastic tank. The at least one reinforcing profile member is configured for arrangement on an outer side of the tank wall to be engaged by the tank wall and establish a positive material bond connection therewith. The at least one reinforcing profile member has a retaining geometry region with a plurality of openings through and/or into which material of the tank wall extends and onto a rear side of the reinforcing profile member facing away from the tank wall to thereby establish the positive material bond connection between the tank wall and the at least one reinforcing profile member at the retaining geometry region.

Disclosed is a hollow molded article which has an opening portion communicating with a flow channel and which can be manufactured simply. The hollow molded article includes a panel and flow channels. The panel includes a first resin sheet and a second resin sheet partly welded with the first resin sheet. The flow channels are disposed between the first resin sheet and the second resin sheet, and include connection portions for external connection which are disposed on a peripheral edge of the panel. The connection portions are formed by the first resin sheet and the second resin sheet.

Arrangement for the transport of media, having at least one base body, wherein the base body forms at least one wall, wherein the wall delimits, at least in sections, two flow channels formed in the base body, wherein the flow channels are separated from one another by at least one separating body arranged in the base body at least in sections.

Measuring pipettes including integral or encapsulated filters, as well as methods and apparatuses for forming the same, are provided. A filter material (e.g., a discrete element in solid form) or a filter material precursor (e.g., a foamable thermoplastic composition and a blowing agent) to be introduced into a hollow interior of a softened thermoplastic material present within a mold during pipette fabrication. A pipette includes a filter element comprising foamed polymeric material within a mouthpiece region, wherein an outer portion of the filter element is bound to or encapsulated in an inner wall of the mouthpiece region. A filter material precursor may be supplied coaxially with a tubular flow of thermoplastic material into the mold, may be supplied laterally through a mold wall, or may be injected into a molten thermoplastic pipette forming material upstream of an extruder outlet.

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.
