11235506 · 2022-02-01 · ·

A method and a molding station for producing containers filled with a liquid filling material from preforms made of a thermoplastic material. Thermally conditioned preforms are molded into containers and filled with the liquid filling material, which is supplied to the preforms under pressure as a pressure medium in a multi-part mold of a molding station. The mold is movable from a closed state into an open state in order to repeatedly supply a preform and subsequently remove a completely molded and filled container. Molding of the preform into the container is performed against the mold inner wall when the mold is in the closed state. Liquid is removed from the mold between temporally successive supplying processes starting with the conversion of the mold from the closed state into the open state. A working wheel including such molding stations, and a device including such a working wheel are also disclosed.

An apparatus (100) for the fabrication of a container (300) comprising a mold (121) defining the form of said container (300) and configured to accommodate a substantially tubular preform, an injection head (115) configured to interface with the preform (108) and establish fluid communication with a cavity thereof; and an injection valve (202), said injection valve (202) configured to selectively permit fluid communication through said injection head (115); said apparatus (100) further comprising at least one compression means (303A, 303B) mobile relative to said mold (121) such that said at least one compression means (303A, 303B) is disposed outside said mold cavity (105) in a retracted position and projects into said mold cavity (105) in an extended position.

CONTAINER BASE INCLUDING HEMISPHERICAL ACTUATING DIAPHRAGM

A container including a finish defining an opening at a first end of the container that provides access to an internal volume defined by the container. A base portion of the container includes a diaphragm that is concave relative to an exterior of the container. The diaphragm extends from a standing surface of the container to a center push-up portion of the base portion. The standing surface is at a second end of the container opposite to the first end. The diagram is configured to move from an as-blown first configuration to a second configuration in which the diaphragm is closer to the first end as compared to the first configuration in order to reduce residual vacuum within the container. The diaphragm is generally hemispherical in cross-section when in the second configuration.
