摘要:
A method for forming a container with an integral handle includes heating a preform having an integral handle in a first oven, stretching the preform, closing a first mold having a first mold recess and a second mold having a second mold recess around the preform, and blowing air into the preform. A handle pocket wedge block is inserted into a handle pocket of the integral handle of the preform within the first mold and the second mold.

A handle for a container capable of providing the container formed in a square shape in cross section, having excellent storability and blow molding properties, preventing various defects from occurring in the container and the handle, and having sufficient strength against falling impact, the container with the handle, and a method of manufacturing the container. The container with the handle is characterized by comprising the polyester container formed of a mouth part, a shoulder part, a body part, and a bottom part in order from the upper part and the polyester handle fitted to a handle mounting projected part of the container. A recessed part is formed in a part of the body part, and the handle mounting projected part is formed on the recessed part. A space part is formed between the wall surface of the handle mounting projected part on the recessed part and the handle. The body part is formed in a square shape in cross section, the recessed part is positioned at the upper half corner part of the body part, and the handle mounting projected part is positioned at the recessed part on the upper half diagonal line L.

The present invention provides a method for manufacturing a heat-resistant handle-equipped container. The method comprises the steps of insert-molding a separate polyester handle onto a top part of a body part of a hollow container when the container is formed by blow-molding a polyester preform and blow-molding with a blow-molding mold positioned so that a central axis of the body part below a handle-attaching convexity provided to a concavity on a top half of the body part is inclined 1°±0.5° toward the handle-attaching convexity; and heat-setting a wall surface that surrounds the handle-attaching convexity in the concavity.

A synthetic resin bottle body with a grip, produced by forming a bottle main body (1) made of PET by biaxial draw blow forming using, as an insert material, a grip (10) formed by injection forming. The bottle main body (1) is shaped such that a vertical projection portion (5) is provided on the center portion at a concave bottom face of a concave portion (3) provided at the rear portion of a trunk portion (2). The grip (10) is shaped such that a grip plate (11) is integrally provided between the upper and lower ends of a pair of assembled beam pieces (12) arranged parallel to each other in a raised position of the bottle body. The width of the grip portion is enlarged from the pair of assembled beams (12) as base end portions toward the tip portion. Fit projections (17) are projected toward substantially the center axis direction of a preform so that a tip face is positioned opposed to the preform outer periphery with the grip being set in a blow-forming mold. An insert portion for the concave bottom face portion near the vertical projection portion (5) of the bottle main body(1) is structured of part of the assembled beam pieces (12) and of the fit projections (17). This way, the insertion capability of the grip (10) is enhanced and fit strength between the bottle main body (1) and the grip (10) is increased.
摘要:
A handled plastic container, the container comprising a blow-molded plastic bottle and a separate handle (18) interconnected thereto wherein the bottle includes a neck including a preformed finish (2) and beneath said finish an outwardly extending flange (6), the container further including an unstretched cylindrical portion below the flange, and a biaxially-stretched and oriented dome below the cylindrical portion, the handle (18) having an upper attachment portion integrated with an upper portion of the dome and including a diverging distal end and a narrower proximal end, the dome being expanded around the diverging end and into contact with the narrower end in order to secure the upper handle attachment to the container, and the handle (18) having a lower attachment portion integrated with a lower portion of the dome.
摘要:
The invention concerns a machine for blowing containers from a preform previously produced by injection, wherein the moulding unit comprises a two-part mould (16), and wherein the container comprises a built-on handle (50) whereof at least one catching zone (51) is engaged inside the cavity (17), and comprising at least a gripping device (42) for gripping a handle (50) by a gripping zone to carry it to the mould (16). The invention is characterised in that the handle-gripping device (42) is borne by a transfer arm (24) for preforms.

摘要:
A method of manufacturing a bottle with a hand-grip, wherein a synthetic resin parison together with a hand-grip member is disposed in a molding tool consisting of two half portions and blow-molded to be integrated with the hand-grip member, characterized in that the parison is disposed in the opened molding tool, the hand-grip member is temporarily fastened to one of the mating mold surfaces of the molding tool consisting of the two half portions, and thereafter, the molding tool is closed for blow molding.
