High density (density 0.945 g/cm.sup.3) unimodal polyethylene compositions for use in hot-fill closures and processes.

A method for filling containers with filling goods that comprise liquid that has a solids content includes using a magnetically inductive flow meter for controlling at least one of volume and quantity of said filling goods in a particular container.

The bottling installation for bottling a liquid in containers includes at least one filler terminal comprising a filler spout (2) comprising a spout body having a top end portion connected to a filler spout feed duct (7) and a bottom end provided with an orifice (8) fitted with a controlled valve, the filler spout being fitted with a feed-back duct (10) opening out into the spout body (6) above the controlled valve (9) and suitable for being connected by a connection member (11) to a general feed duct (12) between a stop valve (14) and an isolating valve (15), a purge valve (17) being connected to the general feed duct (12) between the isolating valve (15) and the connection member (11).

A sealing and pressure dosing apparatus, and container filling method, including a capping machine (102) which receives containers (1). Closures (80) are applied to the containers (1) immediately following the raising of pressure within the containers (1) by a pressure dosing system in a pressure sealing chamber (84). Preferably a cooling system is integrated with the capping machine.

A method for hot-filling a polymeric container with heated product. The method includes mechanically inverting a base of the polymeric container prior to the heated product cooling in order to create a positive pressure within the container prior to cooling, and a vacuum in the container after cooling.

One embodiment of the present invention provides an apparatus for processing sealed plastic containers having a first headspace pressure. The apparatus may include: an open entry port or tunnel for continuously receiving containers; a sanitizer configured to sanitize outside surfaces of the received containers; a perforator configured to perforate or open a cap or seal of the containers within the apparatus; a sealer configured to seal the perforation or opening formed in the cap or seal of the containers; an open exit port of tunnel for continuously exiting the processed containers; and a conveyor system configured to transporting or convey the containers from the open entry port or tunnel, through and within the apparatus, to the open exit port or tunnel and away from the sanitized environment of the apparatus. The apparatus may be further configured to maintain a sanitized environment within the apparatus, perforator, and/or sealer.

A method of processing a plastic container to increase internal pressure including blow-molding the container to comprise an invertible panel in the base and a standing ring, hot filling and sealing the container, feeding the container into an apparatus with a holding device and forcing a volume reduction and pressure increase into the container, and stacking the containers in bulk pallets on top of one another to increase top load and create a positive pressure within the distribution load of containers.
