An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity (116, 16) is provided. A pressure source (120, 20) includes an inlet (146, 150, 46, 50) and a piston-like device (140, 40). The piston-like device (140, 40) is moveable in a first direction wherein liquid is drawn into the pressure source (120, 20) through the inlet (146, 150, 46, 50) and in a second direction wherein the liquid is urged toward the preform (112, 12). A blow nozzle (122, 22) may be adapted to receive the liquid from the pressure source (120, 20) and transfer the liquid at high pressure (P2) into the preform (112, 12) thereby urging the preform (112, 12) to freely expand until an unopened end thereof contacts a platen (118). The platen (118) forms a bottom in a resultant container. The liquid remains within the container as an end product.

A method for producing a tube, which includes: extruding a melt-fabricable fluororesin from a mold of an extruder into a form of a tube, leading the extruded melt-fabricable fluororesin to a cooling device to cool the extruded melt-fabricable fluororesin, and winding a resulting cooled tube onto a winding reel using a winding device. A gas is fed from a head end of the tube wound onto the winding reel into a hollow of the tube, the gas in the hollow is allowed to pass through a gas-introducing entrance of the mold and then through a gas-discharging hole of the mold to discharge the gas outside, thereby allowing the gas to flow along the hollow, and an internal pressure of the hollow is kept higher than atmospheric pressure and lower than 0.5 kgf/cm.sup.2.

A method of manufacturing a fuel tank includes: passing a hollow molten resin projection, that projects-out in a wall-thickness direction and is formed at a molten resin sheet that becomes a tank structural member structuring a tank main body, through a mounting hole of a part-to-be-mounted that is placed on the molten resin sheet; and pressurizing the molten resin projection from an inner side, and causing at least a portion of the molten resin projection to jut-out to a peripheral portion of the mounting hole of the part-to-be-mounted.

The present invention relates to a process for producing a polymer film (P) comprising a polyamide composition (PC) by extruding the polyamide composition (PC) through an annular die and then stretching the tube thus obtained by blowing in air. The present invention further relates to the polymer film (P) obtainable by the process of the invention and to a process for packaging foodstuffs with the polymer film (P).

A compression apparatus (10) for compressing a tubular structure (12) to be formed into a hollow structure (20) such as a pipe comprises contact elements (60) arranged in two sets, (61, 62). The contact elements (60) are adapted to move along a compression section (41) in a coordinated sequence, whereby a portion (12a) of the tubular structure (12) within the compression section (41) is compressed between pairs (63) of opposed contact elements. The apparatus (10) includes registration means (110) for causing respective pairs (63) of opposed contact elements (60) to be maintained in registration with each other while moving along the compression section (41).

An apparatus and method for simultaneously forming and filling a plastic container without the use of a mold forming a mold cavity is includes a pressure source having an inlet and a piston-like device. The piston-like device is moveable in a first direction wherein liquid is drawn into the pressure source through the inlet and in a second direction wherein the liquid is urged toward the preform. A blow nozzle may be adapted to receive the liquid from the pressure source and transfer the liquid at high pressure into the preform thereby urging the preform to freely expand until an unopened end thereof contacts a platen. The platen forms a bottom in a resultant container. The liquid remains within the container as an end product.

A method of fabricating a container from a substantially tubular preform. The preform is preheated to a temperature above the glass-transition temperature of the preform and placed in an expansion zone configured to accommodate the preform and in fluid communication with the nozzle of an injection head. The expansion zone is disposed adjacent to the nozzle and about the longitudinal axis defined by the injection head. A volume of an injection liquid is injected from the injection head into the preform cavity of the preform while the preform is in the expansion zone and the preform is expanded, while still in the expansion zone, into a container. Concurrently with the injecting and expanding of the preform, the preform is heated by energizing a plurality of infrared-emitting elements disposed about the preform and projecting infrared radiation into the expansion zone.
