The present invention relates to a beverage container assembly for holding a beverage. The assembly comprises an outer container defining a body portion and a cylindrical neck portion. The cylindrical neck portion defines a rim located opposite the body portion. The beverage container assembly further comprises an inner bag positioned within the outer container and defining a pressure space inside the inner bag and a beverage space between the inner bag and the outer container. The beverage space is filled by beverage and the inner bag initially defines a folded state. By subjecting the inner bag) to a pressure fluid it is capable of expanding into an unfolded state in which the pressure space at least partially substitutes the beverage space. Both the inner bag and the neck portion are sealed off by a cap at a location between the rim and the body portion.

The invention provides a mould core and injection moulding apparatus for the production of a preform using a mould core which in the zone for defining the neck part of the preform comprises a combination of a raised portion and a shallow groove with a depth of 0.01 to 1 mm provided in the raised portion, for defining an internal attachment means in the neck of the preform. The invention also provides a preform and a container made from the preform, with internal attachment means in the neck. The internal attachment means is carried out rotation symmetrically with respect to the longitudinal axis of the preform. The combinations with an insert piece, preferably a pouring spout, flexible hose or dosing cap, have also been described. Furthermore, the invention provides an injection moulding method for the preform production and a stretch blow moulding method for the container production.

A syringe for use in pressurized injection of a fluid is provided herein. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by compression molding of an inner diameter of the barrel with a core member. In certain configurations of the syringe barrel, the stretch blow molding is provided through a nozzle of the syringe. Similarly, according to a further embodiment, a syringe for use in pressurized injection of a fluid is provided. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by shrinking an inner diameter of the syringe barrel about a core member.

A liquid container and a liquid container with content liquid are easy to sort and dispose of, while preventing dripping of the liquid from a nozzle to the outside. A liquid container includes a container body configured to compartmentally form an accommodation space for content liquid, a tubular nozzle configured to be connected to an upper portion of the container body and guide the content liquid to the outside, and a liquid recovery channel configured to return the content liquid on the radial outside of the nozzle into the accommodation space. The container body, the nozzle, and the liquid recovery channel are formed by integral molding.

A method for producing a pipe assembly which has a base body with at least one channel, wherein at least one functional element is allocated to the channel. The functional element is arranged on a tool carrier, the tool carrier is inserted between blow molding tools of a blow mold, a tubular preform is introduced into the blow mold and is put over the tool carrier with the functional element, the blow mold is closed and the pipe assembly is produced from the preform by blow molding. The functional element is connected to the pipe assembly in a materially bonded and/or form-fitting manner, and the tool carrier is equipped with at least one cutting edge, wherein the blow molding tools bear against the at least one cutting edge when the blow mold is closed and press off the preform so that a separation region is formed.
