摘要： Process for aseptically forming containers (100) starting from parisons made of thermoplastic material, comprising the steps of: injecting sterile compressed air inside a parison arranged in a stretch-blowing forming mould (2) so as to obtain a container (100); evacuating the exhaust compressed air from the formed container (100); making at least a part of the exhaust compressed air evacuated from the formed container (100) passing through a sterile filter (SF) so as to obtain recovery sterile air; injecting the recovery sterile air in another parison arranged in another forming mould (2).

摘要： In one embodiment, a method of processing a plastic container having a longitudinal axis is disclosed. The method includes: blow-molding a plastic container having an upper portion including a finish, a sidewall, a lower portion including a base defining a standing surface, and a substantially transversely oriented pressure panel having an inner annular wall and a central push-up portion located in the base, wherein a base mold portion is displaced longitudinally with respect to first and second side mold portions to form the pressure panel set above the standing surface; introducing heated liquid contents into the plastic container with the pressure panel located in an outwardly-inclined position entirely between the standing surface and the upper portion; capping the plastic container; and, moving the pressure panel to an inwardly-inclined position entirely between the standing surface and the upper portion.

摘要： A method for forming plastic parisons to plastic bottles includes the following steps: introducing in a blow mold a plastic parison to be expanded, the blow mold having at least two lateral parts and a base part that is mobile in relation to said lateral parts in a longitudinal direction of the plastic parison; inserting a rod-shaped element in the interior of the plastic parison through a mouth of the plastic parison; applying a first pressure the plastic parison, applying a second pressure to the plastic parison, the second pressure deviating from the first pressure and being higher than the first pressure, applying a third pressure to the plastic parison, the third pressure deviating from the second pressure and being higher than the second pressure. The base part is advanced in the longitudinal direction of the plastic parison while at least temporarily applying the second pressure to the plastic parison.

摘要： The method relates to a method for filling a container (13, 32) with carbonized liquid filling material and for closing the filled container, in which the filling material is introduced in a filling station (10, 30) by a filling head (11, 33) at defined filling pressure into the container (13, 32), wherein the filling head (11, 33) is firstly moved from an idle position, which permits supplying and inserting a container (13, 32) into the filling station (10, 30), into a working position toward the inserted container, in which an end region (16) of the filling head seals off the opening (14) of the container, the container (13, 32) is then filled, the filling head (11, 33) is moved after completion of the filling phase back out of the working position into an idle position spaced apart from the container (13, 32) and the container (13, 32) is then closed in the filling station (10, 30) using a cap (20) at least enough that filling material can no longer escape, and the container (13, 32) is then removed from the filling station (11, 33), characterized in that before the movement of the filling head (11, 33) from the working position into the idle position spaced apart from the container (13), an overpressure lying between the ambient pressure and the filling pressure is set in a pressure chamber (15) of the filling station (10, 30) surrounding the opening (14) of the inserted container (13, 32), which overpressure is selected in such a way that possible foaming up of the filling material located in the container (13, 32) is minimized enough that filling material does not escape from the container (13, 32) when the filling head (11, 33) is raised out of the working position after the filling procedure.

摘要： A method and apparatus for the formation of double-walled containers with the structure of two integrally connected and adjacent containers extending in the same direction with an air gap between them, stretch-blow moulded as single bodies out of thermoplastic material, and suitable for mass-production. A thermoplastic tubular blank is formed and then heat-conditioned. The heat-conditioned tubular blank is then mechanically stretched longitudinally and blow-formed outwards by gas pressure to conformingly and stretchingly assume the tubular blank to the shape of a first dual-container shaped mould cavity set in order to form a stretch-blow moulded first container integrally connected to a second container, with both containers extending in opposite directions. Next, additional heat-conditioning is applied to further heat-condition as necessary the stretch-blow moulded second container and if deemed an advantage, at least part of the first container. Then at least one profiled inversion piston shaped as a male mould member with an outer surface configuration that defines the inner surface configuration of the article being formed and a second container shaped mould cavity set with a single-container shaped configuration are provided along with one or more wall stability devices which are applied to at least part of the wall surface(s) of either or both of the two integrally connected stretch-blow moulded containers, such that the second smaller container side wall(s) are at least substantially not in contact with the second container shaped mould cavity set and may be inverted at least partially inside-out, while at the same time the second smaller container bottom wall at least substantially does not invert, in order for the second smaller container to become a substantially mirror-image inverted second smaller container extending in the same direction as, and interior to, the first container.

摘要： A method of manufacturing a liquid container, in which, a nozzle unit includes a blow nozzle having a supply port and a spare supply tube having, at a lower end thereof, a spare supply port. The method includes: an air exhausting step of exhausting the air in the preform to the outside by supplying a liquid into the preform from the spare supply port located at a bottom portion of the preform; a liquid blow molding step of molding the preform into a liquid container by supplying a pressurized liquid from the supply port into the preform; and a headspace forming step of forming a headspace by exhausting the liquid from the inside of the liquid container.

摘要： The invention relates to a method for inverting the diaphragm of a filled and capped container. According to the invention, the container is placed on a support ring of an inversion device, a pressing member is applied to the container and a pusher is raised through the support ring to invert the diaphragm and shape the diaphragm into an arch. While the pusher inverts the diaphragm, the seat is moved away from the upper plane of the support ring, so that when the pusher reaches the raised position, a space is opened between the seat and the support ring to enable a longitudinal expansion of the container under the combined effect of the increase in internal pressure caused by the decrease in the volume due to the inversion and the forces generated inside the container by the pusher and the support member.
