Embodiment Construction

[0033] exist figure 1 In the case of the embodiment of the preform (1) which is only partly shown in side view, an annular retaining ring (3) is provided in the region of the mouth (2) on the outside of the preform (1). A fixing ring (3) extends between the threaded part (4) and the side wall region (5) of the preform (1). The threaded part (4) is provided with an external thread (6).

[0034] The retaining ring (3) is usually constructed when the preform (1) is produced by injection molding. The retaining ring (3) and the external thread (6) are molded integrally with the preform (1) as a single piece.

[0035] The retaining ring (3) protrudes transversely beyond the surface of the preform (1) and has a dimension roughly corresponding to the pitch of the external thread (6), however, the dimension is preferably somewhat larger in this direction.

[0036] Where a preform (1) is provided to form a pressurized liquid for containing eg carbonated beverages, one or more vent gr...

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.

Description

technical field [0001] The invention relates to a bottle-shaped container blow molded from thermoplastic material, said container being provided with a mouth and a retaining ring. [0002] Among other things, the invention relates to a preform for producing a container in the shape of a bottle made of thermoplastic material, said preform being provided with a mouth and a securing ring. [0003] The invention also relates to a device with a holding device for handling workpieces made of thermoplastic material, said workpieces having a mouth and a retaining ring. [0004] Finally, the invention relates to a method for processing workpieces made of thermoplastic material, said workpieces having a mouth and a retaining ring. Background technique [0005] Such preforms are typically produced using injection molding methods and are formed from suitable materials such as PET or PP. In order to handle such preforms more easily when performing blow molding operations, when transpor...
