Abstract: A forming method, in a mold fitted with a wall forming a cavity, of a container from an intermediate container including at least one lateral protrusion projecting toward the exterior of the container. The method includes a boxing operation of pushing the lateral protrusion by an insert movably mounted with respect to the mold between a retracted position in which the insert is retracted into a recess formed in the wall and a deployed position in which the insert protrudes with respect to the wall, in order to form, by overturning, a hollow reserve projecting toward the interior of the container. Also included is an operation to pressurize the intermediate container, including, prior to the boxing operation, injecting a fluid under pressure into the intermediate container; and a local pressurization operation, prior to the boxing operation, of injecting a fluid under pressure into the volume defined in said recess between the lateral protrusion and the insert.

Abstract: Device for moulding containers, in particular bottles, from a thermoplastic material such as PET by blow-moulding or stretch blow-moulding of heated preforms, such moulding device comprising at least one mould comprising at least two mould halves respectively comprising two supports and two mould blocks defining a joint plane in the closed position of the mould, each mould block comprising a shell) in which an impression is made partly forming the moulding cavity and a shell-holder fixed to said respective support of the mould block, characterised in that at least one removable spacer is provided between said shell and said shell-holder, as a result of which the dimensional characteristics of the moulding cavity can be modified without the need for intervention on the supports and the shell-holders.

Abstract: Mold for a blow molding machine for manufacturing containers from parisons, the mold including a lateral wall and a mold bottom (7) together defining a cavity for receiving parison, the cavity being generally symmetrical with respect to a main axis, the mold bottom (7) being provided with a gas conduit (12) opening into the cavity for injecting into the same a pressurized gas in order to facilitate withdrawing of the blow molded container, wherein the mold further including a groove (16) provided on an internal face (15) of the mold bottom (7), the groove (16) extending along a closed contour around the main axis, and wherein the conduit (12) opens into the groove (16).

Abstract: The invention relates to a mould (1) for a machine that is used to blow mould containers. The invention comprises: a wall (3) defining a cavity (4) which is distributed around a main axis, said wall (3) being equipped with passages (6, 7) for the circulation of a heat-transfer fluid inside the wall (3); and at least one mould insert (8) which is mounted to the wall (3), said insert being equipped with at least one conduit (17, 23) which is connected to a passage in the wall (3).

Abstract: A mold for a machine which is used for the blow molding of containers from performs. The inventive mold includes a wall defining a cavity that is intended to receive a preform. In addition, the mold includes at least one mold insert which is equipped with a lug and which is mounted such that it can move in relation to the wall by means of a cam system, between: an out position in which the lug projects out at least partially from the wall into the cavity, and a retracted position in which the lug is retracted into the wall. The invention also relates to a method of producing a container by means of blow molding using one such mold.
