Problems solved by technology

[0006] Also, the heating preparation of preforms with solid handles is very complex and difficult since the solid handles do not participate in the stretch-blow molding process, requiring complex shielding to prevent overheating

Embodiment Construction

[0085] In this specification the term "integrally connected" or "integrally connected" means the connection between the handle and the preform (and subsequently the corresponding connection on the container blown from this preform) which is used with The handle is made of the same material as the preform and is formed as an integral part of the handle and preform at the same time that the preform is formed.

[0086] The integrally connected hollow handles according to the invention can take many forms, including handles connected integrally at their top, that is to say against the neck region of the container, or connected at two points to form a loop, the first point of connection facing the neck In the upper area, the second point is towards the bottom of the container, this loop allows the insertion of at least a few fingers to lift the container.

Abstract

A preform for a container comprised of orientable plastics material and arranged so that the resultant blown container will include a hollow handle; said preform comprising a moulded structure having a neck portion and an expandable portion below the, neck, a hollow handle portion of orientable plastics material integrally connected at least at a first end to said preform which when the container is formed constitutes said handle, and wherein interior surfaces of said hollow handle portion form a continuum with interior surfaces of said expandable portion.

Description

technical field [0001] The invention relates to a preform or a semi-finished product and its processing method, in particular to a preform which can be biaxially blown to form a container with an integrally connected hollow handle. Background technique [0002] There have been attempts to combine integral handles with PET as with injection-blow molded containers, see for example US 4,629,598 to Thompson, assignee Tri-Tech Systems International, Inc. Figure 1 shows a semi-finished product or preform that can be manufactured into the bottle with handle of US 4,629,598. However, practical, mass-produced container fabrication attempts of this approach have so far been unsuccessful. As an alternative, what seems to be best done commercially is the solution in which the blown container receives the gripper at the handle in a separate manufacturing stage after forming the container itself. See eg WO82 / 02371 and WO82 / 02370, both of which are Thompson inventors. [0003] The inven...
