Definitions

• the present invention relates to the forming of containers, in particular bottles, flasks or cans, from blanks of thermoplastic material (such as polyethylene terephthalate or PET), and more particularly containers fitted with reserves of hollow for a better grip of said containers.
• thermoplastic material such as polyethylene terephthalate or PET
• the manufacture of said containers generally comprises a blow-molding operation which takes place in a mold whose wall defines a cavity into which the blank is introduced, the latter coming, during the blowing, to marry the wall under the effect of the high gas pressure which reigns in the blank, previously heated to a temperature higher than the glass transition of the material (which is approximately 75°C in the case of PET) so as to allow its plastic deformation.
• the PET blank When the PET blank is introduced into the mould, it is typically at a temperature of around 110°C to 140°C. Blowing is rapid so that when the parison reaches the mold wall, it is still at a temperature of around 100°C.
• EP2106898 European patent EP2106898, filed by the applicant, which describes a plug for the fluidic connection of a container blow mold.
• the document EP2106898 describes a device comprising a mold which comprises two substantially symmetrical half-molds made of a metallic material together forming a generally cylindrical wall of revolution around a main axis and delimiting on an internal face a cavity intended to give its shape to a container made by blow molding or stretch blow molding, in the cavity, of a pre-heated plastic blank to a temperature above its glass transition temperature.
• the wall of the mold comprises, on the side of its upper end, two pipes, each pierced in a half-mold to allow the circulation in the wall of a heat transfer fluid intended to ensure the cooling of said wall of the mold.
• some containers may be provided with recesses formed in the interior of the container and produced for an aesthetic or functional purpose, for example for the creation of curves or for the production of a grip handle respectively.
• a molding unit is generally employed provided with at least one movable insert initially retracted into the wall of the mold and deployed in the presence of the container being formed in the mold to push the material back when it reaches the wall.
• EP3272495 describes a molding unit for forming a container provided with a hollow reserve towards the inside of the container, this forming unit comprising a mold provided with a side wall defining a cavity with the impression of at least a part of the container and integrating a fluidic circuit for thermal regulation of the wall, which opens onto an upper face of the mould, and a boxing device comprising an insert mounted in translation relative to the side wall, an actuator integral with the insert and a pneumatic circuit for controlling the displacement of the piston which comprises at least one primary conduit for supplying the chamber, opening onto the upper face of the mould.
• a difficulty posed by this architecture is that the inserts, in repeated contact with the material of the blank, tend to heat up to reach temperatures of the order of 100°C.
• the part of the blank which comes into contact with the insert is not cooled and remains at a temperature above the glass transition temperature.
• the material of the blank therefore remains malleable and does not have time to cool sufficiently and to freeze before the degassing of the container, which consists in evacuating the blowing air before to remove it from the forming mould.
• the document EP2344320 describes a cooling circuit including channels made in the insert and in which circulates a heat transfer fluid supplied via screws on which the insert is mounted, these screws being themselves fixed on a plate carrying fittings on which are connected flexible pipes for supply and evacuation of the heat transfer fluid.
• This architecture is cumbersome; it is suitable for a linear type mould, in which the wall is subdivided into two half-molds mounted in translation relative to each other, but it is not suitable for a portfolio type mould, in which the space is counted. In particular, it is impossible, in practice, to insert between the mold and its support flexible hoses through which the heat transfer fluid supposed to supply the inserts would be brought. In addition, this architecture makes it necessary to produce a complex circuit for supplying the insert with heat transfer fluid, which includes its own solenoid valves.
