Abstract:
A mold device and a method related thereto for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity, an optional stretch initiation rod system for engaging an interior portion of the preform to define a stretch initiation area, and a centrally disposed pressure source positionable within the preform for introducing a pressurized fluid.
Abstract:
A preform, which makes it possible to obtain PEF containers (bottles) having the awaited properties, notably mechanical, by an industrial injection stretch blow molding process, is of made of a thermoplastic PEF polymer of 2,5-FuranDiCarboxylic Acid (2,5-FDCA) monomer and monoethylene glycol (MEG) monomer and comprises a neck end 2, a neck support ring 3, and a closed tubular body portion 4. The preform is designed so as to produce, by injection stretch blow-molding, a container, the axial stretch ratio of which is greater than or equal to its hoop stretch ratio. Also provided is a plastic container 10, preferably a bottle, obtained by injection stretch blow-molding of PEF preform, the bottle 10 having an axial stretch ratio greater than or equal to the hoop stretch ratio. A method for manufacturing the bottle 10 is also provided.
Abstract:
A molding system for molding a container includes a first blow mold operable for blow molding a first form of the container and a second blow mold operable for blow molding a second form of the container. The system further includes a counter stretch rod and/or a base pushup operable for reducing a height of the first form of the container before blow molding the second form of the container. A corresponding method of forming a container is also disclosed.
Abstract:
The outer circumferential surface of a bottom 4 of a preform 1 and a lower site 3a of a trunk 3 continuous with the bottom 4 is mechanically brought into intimate contact with a cooling pot 16 to undergo reliable cooling. The trunk 3, excluding the lower site 3a of the trunk 3 continuous with the bottom 4, is heated to a predetermined temperature by a heating block 17. When blow-molded, the so treated preform 1 can provide a container having a bottom of a desired thickness and having a uniformly stretched thin-walled trunk.
Abstract:
A preform (1) of plastic material for manufacturing bottles through a blow-moulding process includes a substantially cylindrical central body (3) having an open end (2) and a closed end (4). In correspondence of the central area of the closed end (4) there is provided a hollow appendix (5), projecting outwards of the preform, capable of internally housing the tip end of a stretching rod of the preform (1). Both the hollow appendix (5) and the remaining side portion of the closed end (4) of the preform may be spherical, conical, elliptical or parabolic.
Abstract:
A syringe for use in pressurized injection of a fluid is provided herein. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by compression molding of an inner diameter of the barrel with a core member. In certain configurations of the syringe barrel, the stretch blow molding is provided through a nozzle of the syringe. Similarly, according to a further embodiment, a syringe for use in pressurized injection of a fluid is provided. The syringe includes a syringe barrel comprising a polymeric material having undergone expansion by stretch blow molding and by shrinking an inner diameter of the syringe barrel about a core member.
Abstract:
A preform configured to form a container by stretch blow molding. A finish portion is at a first end of the preform, and is a container finish. A tip portion is at a second end of the preform opposite to the first end, and is configured to form a container base and a container heel. The shoulder portion is adjacent to the finish portion and is between the finish portion and the tip portion. The shoulder portion is configured to form a container shoulder. The body portion is between the shoulder portion and the tip portion, and is configured to form a container body. The outer surface includes a first flat portion and a second flat portion at the tip portion. The first flat portion extends at a first angle and the second flat portion extends at a second angle that is different than the first angle.
Abstract:
A system for forming a container from a preform includes a first mold operable to receive the preform and operable to blow mold a first form of the container from the preform. The system also includes a second mold operable to receive the first form and operable to blow mold a second form of the container from the first form. The preform, the first form, and the second form each include a substantially common transitional wall. Also, the first form can include various features that ensure that material will be distributed as desired throughout the container, to ensure high wall strength, and to ensure high crystallinity.
Abstract:
Disclosed is a preform (300) suitable for subsequent blow-molding into a final-shaped container. The preform comprises a neck portion (302); a gate portion (306); and a body portion (304) extending between said neck portion and said gate portion; the gate portion including an upwardly-bound region (324) defined between the inner and outer walls thereof, substantially whole of the upwardly-bound region extending in a direction towards the neck portion (302).
