A liquid blow molding method molds a bottomed tubular-shaped preform into a liquid-containing container in which a content liquid is held. The liquid blow molding method includes: a filling step of filling a first liquid in a first pressurizing source and filling a second liquid in a second pressurizing source; and a molding step of liquid blow molding the preform by simultaneously supplying, to the preform, the first liquid pressurized to a predetermined pressure by the first pressurizing source and the second liquid pressurized to a predetermined pressure by the second pressurizing source by simultaneously operating the first pressurizing source and the second pressurizing source.

The present invention relates to the use of a polyethylene material in liquid containers that are sterilisable at a temperature of 100 C. during a period of >15 minutes, wherein the polyethylene material has a density >928 kg/m.sup.3 as determined according to ISO 1183-1, method A, and a melt mass flow rate of 0.50 and 51.00 g/10 min as determined according to ISO 1133-1 at a temperature of 190 C. and a load of 2.16 kg; wherein the polyethylene material produced in a high-pressure free-radical polymerisation process at a pressure of 1600 bar.

A hollow preform impact extruded from a metal billet to produce a progressing wall at a transition wall thickness. An axially forward portion of the progressing wall is ironed by extrusion past an extrusion point to form a sidewall portion of a lesser thickness. Extruding is stopped while some of the billet remains to form the closed bottom end. The preform has a bottom portion, a sidewall portion and a transition wall portion extending between the bottom portion and the sidewall portion. The transition wall portion is thicker than the sidewall portion and can be formed into at least part of the rim of an expansion shaped container. An impact extrusion punch has a central axis, an axially forward, impact surface for impacting metal to be extruded, a transition region for directing material displaced by the impact surface and a rear extrusion point for ironing material extruded past the transition region.

A container dispenser system including a container having an orifice. A first dispenser is fitted into the orifice having at least first and second openings, the first opening is configured to allow liquid to exit the container there through and the second opening is configured to allow fluid to enter the container there through. A second dispenser is configured to connect to the first opening in a using configuration. A recess is positioned in an outer surface of the container and the second dispenser is configured to fit into the recess in a storage configuration. The recess has two end portions and a centerline defined there between. At least one portion of the recess is curved such that the centerline curves at least once between the two end portions.

A storage system includes a plurality of vessels each shaped to engage with an adjoining vessel in a top-to-bottom orientation. The volume of the vessels may vary. The lip of each vessel includes a plurality of radially positioned flanges, and the bottom of each vessel includes a plurality of radially positioned locking lugs that correspond and engage with the flanges upon rotation of one vessel relative to the other.

A plastic container includes a neck portion, a sidewall portion, and a base portion. The neck portion includes a plurality of threads, which may be configured to retain and/or secure a cap or lid. In embodiments, the threads may be blown and/or the neck portion may include a neck rib provided vertically above the threads.

A protective bottle enclosure includes a base portion defined by a base sidewall secured to a base bottom wall and has a base opening disposed opposite the base bottom wall. An upper portion has upper sidewalls surrounding an internal cavity. The upper portion has a cylindrical body section and the neck section is narrower than the lower section. The lower section ends in a lower opening and a lower thread. The neck section narrows in diameter between the body section and a neck opening and has a neck thread. The lower section can be inserted into the base opening and can threadably engage the base side wall. A removable cap can threadably engage the neck section and includes an elastomeric stopper connected to a cylindrical sleeve. The combination of the removable cap, the upper portion, and the base portion can surround and enclose the bottle.

A bottle enclosure that removably encloses a bottle includes a base having a sidewall that extends from a bottom wall. The base includes at least one thread, and the base bottom wall has a planar bottom surface. A body section of the bottle enclosure includes a cylindrical body wall that includes interior threading adjacent a bottom opening. The body section further includes a tapered shoulder section that is positioned between the body wall and a neck section. The neck section extends upward from the shoulder section and defines a cylindrical neck wall having a neck thread. The body section is configured to threadably and removably engage the base sidewall. The bottle enclosure further includes a removable cap with a sidewall that surrounds a cap cavity. The cap sidewall is configured to threadably and removably engage the neck.
