A set of preforms to make a container for beverages, comprising an external preform and an internal preform, each intended to form respectively an external keg and an internal bag of the container. The internal preform is associated internally with the external preform in order to define with the external preform a hollow space. The external preform and the internal preform have respective coupling members suitable to clamp the external preform and the internal preform with respect to each other in a desired reciprocal position.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

A container comprises a substantially rigid outer container and a readily deformable inner bag, wherein the outer container and the inner bag consist of different thermoplastic plastic materials such that the outer container and the inner bag do not undergo a weld connection with one another, with a container opening and at least one pressure balancing opening in the wall of the outer container for balancing the pressure in the gap between the outer container and the inner bag when the inner bag contracts, wherein integrated into the layer of the inner bag, which is directed towards the outer container, and/or into the layer of the outer container, which is directed towards the inner bag, are microbodies, of a material which does not melt during the manufacture of the container, which produce irregularities on the surface of the layer(s) in which microbodies are imbedded.

A delamination container includes an engaging protrusion that is provided in an area extending over at least a ground contact portion and a recess and protrudes from either one of an outer layer body and an inner layer body and engages with the other in an undercutting manner. Further, a preform includes an engaging protrusion that is provided in an area extending from at least a boundary between a bottom and a trunk to just before an axial center of the bottom and protrudes from either one of an outer body and an inner body and engages with the other in an undercutting manner.

Tapping assembly for a beverage, including container including a first and second container, wherein the first container has a neck portion and the second container is suspended in the first container, from the neck portion thereof. A neck region of the container is provided with at least one opening in a side wall thereof, preferably in a neck region of the first container, opening into a space between the first and second containers. The assembly further includes a connecting device, connected or connectable to the neck portion, wherein the connecting device includes at least one connecting element for connecting to the at least one opening, wherein the connecting element is connected to a source of pressurised gas.
