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.

Method and device for forming containers with counter-pressure

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.

Device for moulding containers comprising means of adjusting the volume dimensions of the moulding cavity

Mold for a blow molding machine for manufacturing containers from parisons, the mold including a lateral wall and a mold bottom () together defining a cavity for receiving parison, the cavity being generally symmetrical with respect to a main axis, the mold bottom () being provided with a gas conduit () 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 () provided on an internal face () of the mold bottom (), the groove () extending along a closed contour around the main axis, and wherein the conduit () opens into the groove ().

Mold for a container blow molding machine, comprising a grooved mold bottom

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