    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： Provided is a stretching rod for a molding unit for manufacturing a container from a preform and a method for manufacturing a container by stretch blow-molding. The stretching rod extends longitudinally, parallel to a main axis Y, and comprises a body of cylindrical or tubular form, a distal end in the extension of said body, at least one internal channel to allow the circulation of a cooling gas to said distal end, a flat situated at the distal end of the stretching rod, an end-fitting protruding from said flat and a plurality of orifices, said orifices being fluidically connected with said internal channel and being distributed around said end-fitting on said flat. The rod can include an annular skirt in the extension of said body, at said distal end, said skirt having a height less than the height of said end-fitting.

    摘要： Ways for simultaneously forming and filling a container with a product are provided that include a mold cavity, a two-stage injection unit, and a blow nozzle. The mold cavity defines an internal surface and is configured to accept a preform. The two-stage injection unit receives and dispenses the product where a first stage includes an extruder and a second stage includes an accumulator. The extruder imparts mechanical energy to the product to reduce a viscosity of the product and transfers the reduced-viscosity product to the accumulator. The accumulator receives the reduced-viscosity product from the extruder and dispenses a charge of the reduced-viscosity product. The blow nozzle transfers the charge of the reduced-viscosity product dispensed from the accumulator into the preform to urge the preform to expand toward the internal surface of the mold cavity and form a resultant container.
