A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

A molded article suitable for subsequent blow-molding into a final-shaped container. The article includes a neck portion; a gate portion; and a body portion extending between the neck portion and the gate portion, at least a majority of the body portion having an overall shape which is symmetric about a body axis extending longitudinally through a center of the body portion. The body portion includes an inner exterior layer and an outer exterior layer of a first polymeric material; and a core layer of a second polymeric material disposed between the inner exterior layer and the outer exterior layer. A radial thickness or a material of the core layer is selectively varied to govern non-uniform blow molding of the molded article into the final-shaped container.

The present invention relates to an integrally blow-moulded bag-in-container (2) and preform (1, 1) for blow-moulding the bag-in-container. An inner layer (11) and an outer layer (12) are used, wherein the preform forms a two-layer container upon blow-moulding, and wherein the obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface (14) between the two layers. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.

A set of preforms to make a container for beverages comprises 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 so as to define with the external preform a hollow space and also has at least one through hole, made in a neck portion thereof.

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.

Container of a bag-in-container type, wherein a neck region of the container is provided with at least one opening extending substantially radially there through, into a space between the outer container and an inner container adjacent thereto, wherein the neck region is provided with coupling elements, preferably at opposite sides of the at least one opening, seen in circumferential direction, for coupling of a connecting device to the container for introducing a pressure fluid through the at least one opening into a space between the inner and outer container.

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.

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

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.
