... 1378553 Blow-moulding; multi-chamber containers VEREINIGTE DEUTSCHE METALLWERKE AG 7 Aug 1972 [9 Aug 1971] 37039/72 Heading B5A Multi- or two-chamber plastics containers are produced by extruding a thermoplastic tube, longitudinally pinching and fusing the wall of the tubing together along its entire length to divide it longitudinally into two or more cohering but non-communicating component tubes and blow-moulding the component tubes. As shown in Figs. 3, 5, tubing 1 is extruded between the halves 3, 31 of an open blowmould 2 having parting walls 4, 41 which, when the mould closes, pinch the tubing 1 longitudinally to fuse opposite sides together at seam (6, Fig. 2, not shown). A calibrating mandrel 8 having blowing orifices 9, 91 is then used to blow-mould the component tubes into chambers 10, 101 of semi-circular cross-section.

PROCESS FOR THE MANUFACTURE OF CONTAINERS WHICH HAVE AN INTEGRAL HANDLE, AND CONTAINERS MANUFACTURED THEREBY

MANUFACTURE OF BOTTLE WITH PUSH-ON CLOSURE

A method of manufacture of a bottle which may be closed by a push-on closure, apparatus for manufacturing the same, a bottle and a closure for the bottle. A bottle (72) is manufactured in a multi-component assembly. The bottle preform (not shown) is made by an injection moulding technique, having detents on its upwardly and outwardly facing surfaces. It is then transferred to a blow mould where it is first heated, and then shaped by inserting a blow pin (62) through the neck of the preform to stretch it in its longitudinal axis. During this operation, the top surface of the preform is bent down, such that the detent formed on the upwardly facing surface of the preform now extends laterally into the volume of the preform. The stretched preform is then blown to take the shape of the blow mould, forming the bottle (72). A closure is formed by injection moulding, and is held on the bottle by the laterally extending detents.

A PROCESS FOR MAKING A STRETCH-BLOW MOULDED CONTAINER HAVING AN INTEGRALLY MOULDED HANDLE

The present invention relates to a process for making a container having an integral handle, comprising the steps of: a) providing a preform in a mould cavity; b) stretch-blow moulding the preform to form an intermediate container; c) applying one or more inwardly moving plugs to form one or more concave gripping region(s), whilst maintaining the pressure within the intermediate container above 1 bar and whilst the temperature of the material in the gripping region of the intermediate container is at a temperature below the glass transition temperature, T g; d) releasing excess pressure within the container, preferably prior to withdrawing the plug from within the container; and e) ejecting the finished container from the mould cavity.

METHOD FOR PRODUCING A PLASTIC ARTICLE AND BLOW MOLDING TOOL

Disclosed is a method for producing a plastic article. A preform with an approximately C-shaped cross section is formed using melted plastic. The preform is placed between two halves of a blow molding tool, which is then partially closed to clamp the preform with slides that frame a cavity of the blow molding tool as mold spacers and form at least one opening. Differential pressure is applied to the preform to expand the preform into a hollow body within the blow molding tool that has been partially closed. At least one insert is introduced into the interior of the hollow body through an open side of the hollow body in the blow molding tool that has been partially closed. Finally, the blow molding tool is closed completely to form a pinch-off seam which at least partially surrounds the plastic article.

METHOD AND APPARATUS FOR MAKING A BLOW MOLDED FUEL TANK

A fuel tank is formed by a blow molding apparatus and method wherein a blow pin provides pressurized gas into an interior of a parison received in a blow mold so the parison may be blown to shape within the mold cavity. When the blow pin is no longer needed, it is retracted from the mold and a pinch plate assembly is used to close off the opening in the molded part created by the blow pin. Thereafter, the mold may be opened and the molded part removed, the pinch plate assembly is moved back to its retracted position, and the blow mold pin may be advanced into the open mold for use with a subsequent parison so that the subsequent parison can be blow molded in the same manner.

CONTAINER AND METHOD FOR BLOWMOLDING A BASE IN A PARTIAL VACUUM PRESSURE REDUCTION SETUP

Изобретение относится к способу изготовления бутылки, которую можно закрывать напрессовываемой крышкой, к оборудованию для изготовления бутылки, к бутылке и к крышке для бутылки. Техническим результатом изобретения является создание средства для изготовления бутылки с напрессовываемой крышкой, которое можно было бы применять для производства пластиковой бутылки и/или крышки без необходимости использования металлической гофрированной корончатой крышки, но при котором сохранялись бы преимущества корончатой крышки. Способ изготовления бутылки, которую можно закрывать напрессовываемой крышкой, оборудование для изготовления бутылки, бутылка и крышка к бутылке. Бутылку изготавливают на многокомпонентном оборудовании. Предварительно отформованную заготовку (преформу) бутылки изготавливают способом литья под давлением; причем заготовка содержит упоры на обращенных вверх и наружу поверхностях. Затем преформу переносят в пресс-форму для выдувания, где ее сначала нагревают, а затем формуют путем введения штока через горлышко преформы для вытягивания ее в ее продольном направлении. Во время выполнения этой операции верхнюю поверхность преформы отгибают вниз так, чтобы упор, сформованный на обращенной вверх поверхности преформы, теперь выступал в поперечном направлении в объеме преформы. Вытянутую преформу затем раздувают для того, чтобы она приняла форму пресс-формы для раздувания, в которой формуют бутылку. Крышку формуют способом литья под давлением. И ее удерживают на бутылке с помощью выступающих в поперечном направлении упоров. 5 н. и 14 з.п. ф-лы, 19 ил.
