Abstract: Disclosed is a device for distributing thermoplastic material to a preform molding machine, the preforms being used for manufacturing containers; the device includes at least a stationary part and a movable part, a seal that has a first sealing surface and a second sealing surface which are axially separated from each other by a gap inside which some of the thermoplastic material flows, a channel for radially constraining the thermoplastic material, and an associated cooler for radially obtaining a temperature gradient in order to increase the viscosity of the thermoplastic material located between the sealing surfaces.

Abstract: A nozzle (10) for forming containers made of a thermoplastic material by injecting a pressurized fluid into a neck (14) of a preform (12), includes: a mounting (24) which is provided with an inlet pipe (36) for a pressurized fluid along a vertical axis (A); a nozzle tip (26) which axially extends the inlet pipe (36), and which can be sealingly coupled to the neck (14) of the preform (12) via at least one element (42, 44) matching the format of the neck (14); an element for removably attaching the nozzle tip (26) onto the mounting (24); and a stabilizing tube (106) resiliently biased toward the lower stop position thereof via a resilient member (116) that is permanently accommodated in the mounting.

Abstract: A member (22) for gripping vessels (16) includes: a support (32) that moves along a transport trajectory of the vessel (16); a nose (38) including a mandrel (40) capable of holding a neck (26) of the vessel (16), the nose (38) being fixed removably to a bottom axial end of the support (32); characterized in that the nose (38) includes an ejection plate (46) which is mounted to slide axially around the mandrel (40) between a cladding position towards which it is elastically returned and in which the mandrel (40) protrudes axially downwards and an uncladding position in which the mandrel (40) is axially retracted above a bottom face of the plate (46). A device for replacing such a gripping member is also described.
