摘要:
Systems and methods for making a reduced material container are provided that hold a preform adjacent to an open end of the preform, stretch the preform, close a mold about the stretched preform to form a truncated preform, and introduce a pressurized fluid into the truncated preform to expand the truncated preform and form the reduced material container. A stretch rod can be inserted into the preform to mechanically stretching the preform. The mold accepts the preform at a first end thereof, has an open state and a closed state, and the closed state forms a cavity defining an internal surface having a second end located remotely from the first end. A first length is defined by a distance between the first end and the second end, the stretch rod mechanically stretching the preform to a second length, the second length being greater than the first length.

A vessel is configured to hold a product in an interior region formed in the vessel. The vessel includes an inner layer arranged to define the interior region and an outer layer. The vessel is formed using a blow-molding process in which a multi-layer parison is blow molded to form the vessel. The multi-layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated inner and outer parisons to establish the multi-layer parison.
摘要:
A blow mold for making PET containers comprising an inner surface corresponding to the outer outline of the container, on which there are one or more cavities or projections configured to make corresponding respective projections or cavities of the outer surface of the container, wherein the mold comprises one or more venting grooves along the edge delimiting said cavities or projections. A plurality of venting holes are possibly arranged along such grooves, as well as it is also possible for some venting holes to be arranged outside thereof. The width and depth of these are selected according to the wall thickness of the container to be blown to prevent that the deformation of the container during the blowing obstructs the venting grooves and leaves visible marks on the container.
摘要:
A method of manufacturing a resin-laminated board by preparing a pair of first and second split molds each of which is provided with a cavity; positioning two sheet materials made of a thermoplastic resin between the first and second split molds with the cavities of the first and second split molds opposed to each other; forming a plurality of recesses by recessing a first sheet material toward a second sheet material with use of a plurality of protrusions provided to the first split mold; and welding bottoms of the recesses to the second sheet material by clamping the pair of first and second split molds to obtain a resin-laminated board with a hollow structure. A mold includes a plurality of piece members, disposed at the cavity of the first split mold; and includes the protrusions and male screws provided to base ends of the protrusions.
摘要:
A method for producing a container (2) from a blank (3) in a mould (1) provided with a wall (4) and a mould bottom (8) that is movable relative to the wall (4) between a retracted position and a deployed position, the method including: a phase of introducing the blank (3) into the mould; a preblowing phase including the injection, into the blank (3), of a fluid pressurised to a so-called preblowing pressure, a blowing phase following the preblowing phase and including the injection, into the blank (3), of a fluid pressurised to a so-called blowing pressure greater than the preblowing pressure; a boxing phase including the displacement of the mould bottom (8) from the retracted position thereof to the deployed position thereof, initiated after the pressure in the blank (3) has reached the blowing pressure.
摘要:
Apparatus for the shaping of plastics material pre-forms into containers includes at least one blow mold with two blow mold parts movable with respect to each other. The blow mold forms a cavity inside which the pre-forms may be shaped into the containers. The apparatus includes a stressing device which acts upon the pre-forms with a flowable medium for their expansion, a conveying device which conveys the blow mold along a pre-set conveying path, and a clean room inside which the blow mold may be conveyed during the expansion of the pre-forms. An inner wall of the blow mold facing the pre-form has at least one opening through which a flowable medium may be removed out of the cavity during the expansion procedure. A flow connection provided between the opening and the clean room is sealed off from a non-sterile environment of the clean room.

A blow moulded plastic bottle includes a neck, a shoulder, a tubular body portion, and an integral bottom structure including: a terminal curved portion, an internal axially inwardly directed dome, and an (annular) base joining the terminal curved portion to the dome; wherein: a spline comprises a flat part in the base plane (Pb) onto the bottle rests when it stands up; the height (h1) between (Pb) and the apex of the dome, the height (h2) between (Pb) and the spline diametral median plane (Pd) which is in the middle of the spline (17) and which is parallel to (Pb), and the maximum external diameter (Dm) of the tubular body portion, being so that [(h1)/(Dm)]*100 is comprised between 14.0 and 16.0% and (h1)
摘要:
A process and a device for the manufacture of a hollow body, particularly of a heat-resistant hollow body, which is molded out of a heated preform of thermoplastic plastic in a contoured blow mold through the introduction of a first medium into the preform, which medium is stored in a first medium storage unit and is under a pressure (p1) (preblowing phase), and the more or less simultaneous stretching of the hollow body through a stretching rod and the introduction of a second medium in the hollow body, which medium is stored in a second medium storage unit and the pressure of which (p2) is higher than the pressure of the first medium (p1) (final blowing phase), and which is cooled by a third medium, which is medium stored in a third medium storage unit (rinsing phase), whereby the preblowing medium is under a pressure of approximately 2-20 bar, the final blowing medium is under a pressure of approximately 15-45 bar, and the cooling medium is under a pressure of approximately 30-45 bar.
