A finish of a preform and a container formed from the preform. The finish has a brim defining an opening of the finish. The brim is configured to provide a sealing surface with a forming and filling head for forming the container from the preform and filling the container with a product. A support flange extends from an outer side surface of the finish. The support flange includes an undersurface having an inner portion that is directly opposite to the brim. The inner portion of the undersurface of the support flange is closer to an axial center of the finish than an innermost portion of the outer side surface.

A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.

Disclosed is an injection stretch blow molded (ISBM) container containing a surface having a static coefficient of friction (COF) of 0.15 to 0.21, a dynamic COF of 0.06 to 0.1, wherein the surface retains a water contact angle of 76° or higher for up to three minutes after wetting of the surface with a water drop of 14 to 16 mm diameter and the container is made with a polymeric composition containing a high density polyethylene (HDPE) having a dispersity (Mw/Mn) of 9 or higher as measured by GPC; a MI2 of 1 g/10 min or higher as measured by ASTM D-1238; 190° C./2.16 kg, as measured by ASTM D-1238; and an environmental stress crack resistance (ESCR) at 100% Igepal of >150 hours as measured by ASTM D-1693, B.

The invention relates to a method for manufacturing containers by blow-molding or stretch-blow-molding from plastic preforms, the method comprising a step of cooling a mold bottom by circulation of a heat transfer fluid inside a cavity of the mold bottom, the step of cooling a mold bottom being carried out with a non-refrigerated heat transfer fluid at a temperature lower than or equal to 30° C.

Ways of simultaneously forming and filling a container include and/or use a mold (14), a pressure source (20), a blow nozzle (22), and one or more dampening means. The mold (14) has a cavity defining an internal surface and is configured to accept a preform (12). The pressure source (20) is configured to provide a pressurized liquid (18). The blow nozzle (22) is configured to receive the pressurized liquid (18) from the pressure source (20) and transfer the pressurized liquid (18) into the preform (12) to urge the preform (12) to expand toward the internal surface of the mold cavity (16) and form a resultant container, where the liquid (86, 96) remains within the container as an end product. The one or more dampening means is/are configured to reduce water hammer, for example, by coupling such dampening means to one of the blow nozzle (22) and the mold (14).

A manufacturing method includes an injection molding process of injection-molding a preform having a two-layer structure including an outer layer preform and an inner layer preform, and a blow molding process of blow molding the preform to mold a delamination container made of resin. The injection molding process includes an outer layer molding process of filling an outer layer injection mold with PET (outer layer resin material) to mold the outer layer preform and molding a thin film portion in a part of the outer layer preform, and an inner layer molding process of injecting PP (inner layer resin material) toward the thin film portion to break the thin film portion and filling an inner layer injection mold with PP having a temperature lower than a melting point of PET via the broken thin film portion to mold the inner layer preform.

A temperature adjusting unit of a blow molding apparatus includes: a first drive unit configured to drive a core mold, from which the cooling air is supplied, in a first direction; a second drive unit configured to drive a cavity mold that accommodates the preform in a second direction; a first lock portion configured to restrict a movement of the first drive unit in the second direction at a first position where the core mold is inserted into the preform; and a second lock portion configured to restrict a movement of the second drive unit in the first direction at a second position where the preform is accommodated in the cavity mold.

A method for producing a multiple preform, including a primary injection for injection molding a preform main body using a primary mold, and a secondary injection for injection molding, using a secondary mold, a covering layer that covers the preform main body such that the terminal end side of the covering layer covers the lower surface of the neck ring and reaches the peripheral edge of the neck ring. A projection strip portion is formed when the preform main body is inserted into the secondary mold to be clamped, that projects in a gap in which the covering layer is molded to be in contact with or adjacent to a lower surface of the neck ring, and that extends with a given length along an axis direction, is formed on an inner peripheral surface of the secondary molding mold, thereby forming an easy tear portion in the covering layer.

Article having a body portion including one or more walls surrounding an interior space. The one or more walls have an inner surface, an outer surface, a wall thickness, a transparent portion, and one or more aesthetic regions having oblong voids provided between the inner surface and the outer surface within an outermost 70% of the wall, and the one or more aesthetic regions are provided in a predetermined pattern.

A method for manufacturing a container includes injecting a first material into a first mold to form a top portion of a preform. The first material and a second material are injected into the first mold to form a bottom portion of the preform. The preform is disposed in a second mold. The preform is blow molded into a finished container.
