A device includes a first part having a co-molded first support, valve cover and elastic actuator, and a second part having an injection molded second support, valve seat, and variable-volume storage chamber pre-form. The pre-form is blow molded into a flexible pouch defining the variable-volume storage chamber. The one-way valve includes a semi-annular, curvilinear, relatively rigid valve seat defining axially-extending, opposing first marginal portions, and an axially-extending first mid-portion angularly extending between the opposing first marginal portions. A flexible valve member is superimposed on the valve seat and defines axially-extending, opposing second marginal portions fixedly secured on or adjacent to respective first marginal portions of the valve seat, and an axially-extending second mid-portion angularly extending between the opposing first marginal portions and superimposed onto the first mid-portion of the valve seat. The flexible valve cover and valve seat form a normally closed axially and angularly extending valve seam therebetween.

A blow molded synthetic resin bottle has a body and an elongated neck with the body providing a shoulder extending about the base of the neck. The neck has a first collar extending thereabout spaced adjacent the shoulder and at least one additional collar extending thereabout adjacent the upper end of the neck. The resin in the neck is substantially unoriented. To produce the bottle, a synthetic resin preform is injection molded with a generally tubular body and the elongated neck. This preform is placed in a blow mold cavity having a body receiving portion and a neck receiving portion that has a recess extending thereabout seating the first collar therein. The additional collar is disposed outwardly of the mold cavity and is disposed on the upper surface of the mold.

A stretch blow-molded plastic container, including a container body, one longitudinal end of which is closed by a container bottom and to whose other longitudinal end is connected a shoulder section; and a container neck, which connects to the shoulder section, the shoulder section having at least two hinge-like areas that run in a circumferential direction, and which areas are arranged at a distance (a) from one another and in each case have a wall thickness (v, w) that is reduced compared to the adjoining areas, the stretch blow-molded plastic container having a total stretching ratio of greater than 11 for a longitudinal stretching ratio of 2.5 to 3.5.

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 pressurized gas.

The present invention provides a valve cup (10) for use with a container (30) for dispensing a fluid medium stored under pressure. The valve cup (10) supports a valve (50) and seals an opening (32) of the container (30) and is formed from a semi-crystalline polyester. The present invention also provides a container (30), wherein at least a part of the container (30) surrounding an opening (32) is formed from a semi-crystal-line polyester. A further valve cup (10) is formed from a metal or rigid material and further includes a polyester lining (70). Dispensing systems (1) including the above containers (30) and valve cups (10) are provided, wherein welding is facilitated between the container (30) and valve cups (10).

A blow molded synthetic resin bottle has a body and an elongated neck with the body providing a shoulder extending about the base of the neck. The neck has a first collar extending thereabout spaced adjacent the shoulder and at least one additional collar extending thereabout adjacent the upper end of the neck. The resin in the neck is substantially unoriented. To produce the bottle, a synthetic resin preform is injection molded with a generally tubular body and the elongated neck. This preform is placed in a blow mold cavity having a body receiving portion and a neck receiving portion that has a recess extending thereabout seating the first collar therein. The additional collar is disposed outwardly of the mold cavity and is disposed on the upper surface of the mold.

The invention relates to a preform for producing a plastic container in a 2-stage stretch blow molding method, said preform having a preform body that extends along a central axis and that comprises: a first end a second end that lies opposite the first end, wherein the first end is closed and a neck part with a pouring opening adjoins the second end; and an inner wall that delimits an interior of the preform. Along a length of at least 30 mm of the interior, every point of the inner wall is at a distance of less than 3.5 mm from the central axis. Also disclosed are a suitable method and a device for producing such a preform.

Method for producing a plastic bottle, and preform and blowing mold suited therefore are disclosed. An exemplary process can produce a plastic bottle, for example, a PET bottle. Such a bottle can be produced from a preform which has a body which is closed on one side, which is connected to a neck section with a pour opening, in which the preform which has been produced in a plastic injection process or an extrusion process is placed in the mold cavity of a blow mold and inflated using the blow nozzle by overpressure according to the mold cavity. Sealing can take place between the blow nozzle and the preform within the preform.

A preform assembly includes: an outer preform that includes an outer mouth portion and a stretch portion connected to the outer mouth portion and in which a recess extending in a vertical direction is provided on an inner surface of the stretch portion; and an inner preform that includes an inner mouth portion and a stretch portion connected to the inner mouth portion, wherein an outside air introduction port communicating with a part between the outer preform and the inner preform is provided in a mouth portion composed of the outer mouth portion and the inner mouth portion located on an inner side of the outer mouth portion.
