A hollow container producing device for producing a hollow container using a pair of parison sheets is provided. The hollow container producing device includes a pair of molds; an intermediate frame to be clamped to the pair of molds; and a transport unit that carries the intermediate frame and a pair of parison sheets to a position between the pair of molds, with the pair of parison sheets being respectively held on opposite sides of the intermediate frame.

A one-piece mold element (3, 7) for a mold (1) for manufacturing containers from blanks of plastic material by blow molding or stretch blow molding. The mold element (3, 7) includes a one-piece molding wall (4, 8) having a raised molding surface (5, 9) bearing the imprint of at least one portion of a container, the molding wall (4, 8) having at least one decompression vent (20) extending therethrough, the hole leading, via an inner opening (21), onto the molding surface (9), which is provided in the form of a slot.

Conditioning station tooling for adjusting a temperature of a preform. The tooling comprises a mold presenting a cavity configured to receive at least a portion of the preform. The mold is configured to receive the preform such that a gap is present between the mold and the preform. The mold includes an air inlet and an air outlet. The tooling is configured to permit air to be injected from the air inlet, through the gap between the mold and preform, and out of the air outlet. The tooling further comprises a core configured to be received within an interior of the preform and to contact an interior surface of the preform.

Even when the filling speed increases, the surface temperature of a molded bottle falls within a constant range, and a sterilizer adequately sterilizes the bottle. A preform is heated, the heated preform is sealed in a mold, the preform sealed in the mold is blow-molded into a bottle, the surface temperatures of a neck portion, a body portion, and a bottom portion of the molded bottle are measured, and the mold temperatures of a neck portion, a body portion, and a bottom portion of the mold is so adjusted that the measured surface temperature of the bottle falls within a specified temperature range.

A method for transferring a negative structure of a surface of an inner wall (51) of a blow molding tool (1) onto a surface of a plastic container. The method comprises the steps of heating at least one region (511) of a mold cavity (6) of a molding body (4) of the blow molding tool (1), on which the negative structure is formed, inserting a preform into the mold cavity (6), closing the blow molding tool (1), molding the plastic container by inflating the preform and bringing the preform to lie against the inner wall (51) of the mold cavity (6), cooling the region (511) by supplying a coolant through temperature control channels (54), and removing the plastic container from the mold.

Disclosed is a method for molding plastic preforms into plastic containers using a blow mould assembly including a blow mould unit, wherein a part of the blow mould unit is retained on a blow mould holder element using negative pressure.

A blow mold provided with a locking system for mutually locking each half-mold with the related half-mold holder, thus allowing a simpler and quicker replacement of the side half-impressions of the mold. The blow mold of the invention provides for the side half-impression of each half-mold to be fixed in a cavity of the corresponding mold holder by actuating at least one quick coupling device comprising a bar (23) inserted in one of the two longitudinal edges of the half-mold holder (3) and adapted to move only by rotation about an axis thereof; actuation means (22) adapted to actuate a rotation of said bar; and at least one locking fin (21) fixed along said bar (23) and adapted to move, by rotating the bar (23), from an unlocking position to a locking position in which said locking fin interacts with the respective half-mold (2).

A one-piece mold bottom (7) for a mold (1) for manufacturing containers, includes a molding wall (8) having a raised molding surface (9) bearing the imprint of at least one portion of a container bottom. The mold bottom (7) includes a cavity (27) integrally formed with the mold bottom (7), defined by a surface casing (29) defined entirely by the mold bottom (7) and including an inner surface (31) of the molding wall (8), opposite the molding surface (9) and matching the raised pattern thereof, and a rear surface (32, 33) opposite the inner surface (31). The mold bottom (7) is provided with at least one pair of openings (35; 37) leading into the cavity (27) for circulating a heat-transfer fluid inside the cavity.

A container, preferably a bottle, is fabricated in a method comprising: providing a preform comprising poly(ethylene 2, 5-furandicarboxylate); stretch blow-molding the preform to form the container, wherein the stretch blow-molding comprises a stretching step of the preform to a ratio higher than the natural draw ratio of poly(ethylene 2, 5-furandicarboxylate) at a temperature in a range of 105? C. to 145? C., preferably in a range of 110? C. to 140? C., and at an equivalent axial strain rate at a reference temperature of 100? C. in the range of 0.001 to 10 s.sup.?1, preferably in a range of 0.03 to 3 s.sup.?1.

The invention relates to a blow molding tool for a blow molding machine for producing plastic containers in an extrusion or stretch blow-molding process. The blow molding tool comprises two blow mold halves, each of which comprises at least one molding body in which at least one mold cavity is disposed, and a baseplate that receives said molding body. An insulation block consisting of a thermally insulating material is arranged between the molding body and the baseplate and, optionally, further components of the blow mold halves.
