Abstract:
A plastic material container, e.g. a beverage bottle, having a neck which requires the use of a smaller amount of plastic than the bottle necks of the prior art, and which is able to ensure a complete functionality for coupling the cap, ensuring at the same time the possibility of implementing the traditional supporting; sealing and handling operations of the bottle carried out during the various steps of manufacturing the same.
Abstract:
There is provided a stripper assembly (212) for use in a mold stack (202) for forming a preform (210) suitable for blow-molding into a final-shaped container. The stripper assembly (212) comprises a stripper plate (214) connectable, in use, to a stripper plate actuator; neck rings (220) configured to cooperate to define a portion a neck region (226) of the preform (210); a stripper ring (230) configured to define at least a portion of a top sealing surface of the neck region (226) of the preform (210); the stripper plate (214) being configured to actuate the neck rings (220) and the stripper ring (230), in unison, along substantially the whole length of a complete ejection path, which is substantially parallel to a longitudinal axis of the mold stack (202); and wherein the neck rings (220) are configured for movement in a direction substantially perpendicular to the longitudinal axis of the mold stack, over at a portion of the complete ejection path, the stripper ring (230) having an air channel (236) configured to directed a flow of fluid towards the preform.
Abstract:
Method for producing a plastic bottle, and preform and blowing mold suited therefore are disclosed. An exemplary process can produce a plastic bottle, for example, a PET bottle. Such a bottle can be produced from a preform which has a body which is closed on one side, which is connected to a neck section with a pour opening, in which the preform which has been produced in a plastic injection process or an extrusion process is placed in the mold cavity of a blow mold and inflated using the blow nozzle by overpressure according to the mold cavity. Sealing can take place between the blow nozzle and the preform within the preform.
Abstract:
A plastic preform has a base body, and a threaded area disposed on and integrally formed with the base body. An integrally formed annular section extends outwards in a radial direction from the base body, below the threaded area. The annular section has a first surface facing the base body and a second surface facing the threaded area. A marking characteristic of at least one property of the plastic preform is located on a surface section of the plastic preform below the threaded area, in the longitudinal direction of the plastic perform, extending at an angle of non-zero in relation to the longitudinal direction of the plastic preform.
Abstract:
An injecting/blowing device includes a mold for injecting a thin-walled hollow preform capable of being transformed into a more voluminous hollow body. The mold includes a counter mold defining a cavity, a cure located in the cavity, and a preform impression located between the counter mold inner surface and the core which will receive the melt, at least two main preferential flow channels or at least two secondary preferential flow channels having a recessed zone at the surface of the core and the inner surface of the cavity. The main flow channels are located only at the impression zone corresponding to the zone for transforming the preform, and in the optional secondary flow channels are flow channels discontinuous from the main flow channel.
Abstract:
The container has a bottle-like shape and is made of thermoplastic material. The container is provided with a mouth section which has a fixing ring (3) on the outside. The pre-form is provided for the production of such a container. Both the pre-form and the container produced therefrom are designed without any supporting ring. In order to enable handling, an associated holding device (12) acts on a fixing ring (3) of the pre-form or the container.
Abstract:
A biaxially drawn, blow molded bottle characterized in that vertical connecting zones having no intermediate layer and having substrate layers welded directly with each other are formed in parallel in a circumferential direction and in a plural number along an axial direction of the bottle and are disposed on both right and left sides of each intermediate layer segment to be formed in this height range, and that horizontal connecting zones having no intermediate layer and having substrate layers welded directly with each other are also formed in parallel in an axial direction and in a plural number along a circumferential direction of the bottle and are disposed on both upper and lower sides of each intermediate layer segment to be formed, thus allowing the intermediate layer to be segmentalized in the circumferential and axial directions by both the vertical and horizontal connecting zones.
Abstract:
A process for the manufacturing and filling of plastic containers, said process comprising the steps of: a. positioning a preform (1) with relation to a mold assembly of two or more components (20, 21, 22), said preform generally being fabricated from a plastic and being provided with a longitudinal axis (17) and presenting a stretchable portion (13) and a non-stretchable portion (11); b. stretching said preform along its longitudinal axis (17); c. injecting a fluid (29) into the interior volume (6) of the preform (1), said fluid (29) being under such pressure as to cause the preform (1) to plastically deform until achieving the desired size and shape; and d. releasing said container from the mold assembly (20, 21, 22) and sealing the container, and in which at least a portion of the stretchable portion (13) of the perform (1) is at a temperature below its vitreous transition temperature (Tg) and, preferably, at ambient temperatures.
Abstract:
A process for producing cellular thermoplastic articles. The process comprises the steps of treating a solid parison made from a thermoplastic material with a saturating gas at an elevated pressure for a period of time to provide a gas-saturated parison; heating the gas-saturated parison to prepare a cellular parison; placing the cellular parison in a mold; and blowing a molding gas into the cellular parison to expand the cellular parison into the shape of the mold to provide a shaped cellular article.
Abstract:
A polyester container with enhanced gas barrier properties includes a polyester composition having an IV of 0.65 dL/g to 1.0 dL/g and including a polyester and a reactive organic gas barrier enhancing additive. The polyester is made using at least one first polycondensation catalyst, non-limiting examples of which include metals in Groups 3, 4, 13, and 14 of the Periodic Table and includes a catalyst residue remaining in the polyester from formation of the polyester. The catalyst residue includes at least a portion of the at least one first polycondensation catalyst.
