20120098167 | METHOD OF TREATING A HOT FILLED PLASTIC THIN WALLED CONTAINER AND ASSOCIATED DEVICE - A process for treatment of a thin-walled plastic container, the container having residual stresses resulting from its manufacture from a preform, which has been hot-filled and stoppered with liquid contents and then cooled once filled and stoppered, and being designed to undergo stress relief by a heat treatment, characterized in that it includes a stage prior to that of the heat treatment that consists in exerting mechanical force on the external surface of the thin wall of the container that is deformed by the hot filling to generate an interior pressure so as to compensate for at least the underpressure to which it is subjected and to restore its initial shape to it. An associated device for the implementation of the process is also described. | 04-26-2012 |
20110266722 | METHOD FOR PRODUCING A THIN-WALLED CONTAINER - This invention relates to a method for producing a thin-walled container, characterized in that a preform is deformed using a weight/wall surface ratio on the order of about 150 g/m | 11-03-2011 |
20110266186 | THIN-WALLED PLASTIC CONTAINER FOR PRESSURIZATION - This invention proposes a light-weight, thin-walled plastic container, in particular made of polyethylene terephthalate (PET), intended for post-filling pressurization so as to increase the rigidity of said container, and a process for manufacturing such container. | 11-03-2011 |
20110068112 | HEAT RESISTANT PLASTIC CONTAINER - A heat resistant plastic container containing hot-filled liquid contents, comprising: a spout for filling the container with liquid contents; a closure configured to seal the spout; a base including a bottom portion that is bent toward the spout, the base including a structural reinforcement; and a sidewall extending upwardly from the base toward the spout, the sidewall including a zone of deformation, wherein the zone of deformation in the sidewall is configured to accommodate an initial deformation due to the cooling of the contents and to substantially regain its initial shape upon the relieving of immobilized stresses. | 03-24-2011 |
20100181281 | HEAT RESISTANT PLASTIC CONTAINER - A lightweight, thin-walled heat resistant plastic container containing hot-filled liquid contents, comprising: a spout for filling the container with liquid contents; a closure configured to seal the spout; a base including a bottom portion that is bent toward the spout, the base including a structural reinforcement configured to withstand hydrostatic pressure from the hot-filling of liquid and configured to prevent significant deformation in the base upon the cooling of the hot liquid; and a sidewall extending upwardly from the base toward the spout, the sidewall including a zone of deformation, wherein the zone of deformation in the sidewall is configured to accommodate an initial deformation due to the cooling of the contents and to substantially regain its initial shape upon the relieving of immobilized stresses. | 07-22-2010 |
20100180981 | Process for filling a plastic container - A process for filling a container with a liquid, including the following steps:
