Method for controlling a method for the manufacture of a container by stretch-blow-molding of a plastic preform (2) in a machine (1) including a mold (26), the preform (2) having a body (3), a neck (4) opening at one end of the body (3) and a bottom (5) closing the body (3) at another end thereof, the manufacturing method including the operations involving:heating the preform to a predetermined temperature in a thermal conditioning oven (10);introducing the preform (2) into the mold (26);moving a stretching pin (28) so as to stretch the preform (2); this control method involving a step that consists in determining the position of impact (P0r) of the stretch pin (28), namely the position it occupies at the moment at which it reaches the bottom (5) of the preform (2) during its movement.

A continuously rotating, non-symmetric preform feed, stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric injection moulded preforms; the non-symmetric preforms including an integral handle extending from a first junction point to a second junction point on a body of the preform; the body of the preform and the integral handle constituted from the same material.

Apparatus for producing containers, and in particular beverage containers, having a heating device configured to heat plastic parisons, having at least one first transport device, which transports the plastic parisons along a predetermined transport path, a sterilization device configured to sterilize the plastic parisons, and a forming device arranged downstream of the sterilization device, as seen in a transporting direction of the plastic parisons, and configured to form the plastic parisons into plastic containers by the application of a free-flowing medium, wherein said forming device has a transport chamber within which the plastic parisons are transported. The apparatus has an application device configured to apply a free-flowing sterilization medium, at least temporarily, to the transport chamber.

A method for renovating the interior of a hollow structure such as a sewerage pit (1) is described. The method provides an access opening (16) to the hollow structure (1); provides a plurality of material sheets (3) comprising reinforcing fibers and a curable resin composition through the access opening (16) and against a wall (11a, 11b) of the hollow structure (1); and provides an inflatable pressure means (4a, 4b) within the hollow structure (1). The pressure means (4a, 4b) are inflated against the wall (11a, 11b). A curing means (6) is then provided within the hollow structure (1) for curing the resin composition; and the resin composition is cured to harden the material sheets and provide a renovated interior of the hollow structure (1).

The present invention relates to an integrally blow-moulded bag-in-container (2) and preform (1, 1) for blow-moulding the bag-in-container. An inner layer (11) and an outer layer (12) are used, wherein the preform forms a two-layer container upon blow-moulding, and wherein the obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface (14) between the two layers. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.

A blow molding apparatus includes: an injection molding section for injection molding a plurality of preforms at a time; a cooling section for cooling the preforms; a heating section for heating the preforms while continuously transporting them along a transport line; and a blow molding section for blow molding the preforms to form hollow containers.
