Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the problem that wrong plastic container blanks are not easy to be detected in the prior art, resulting in failure to remove wrong plastic container blanks from the blow molding machine in time and thus causing failure of the production line Disadvantage, to provide a plastic preform which enables a better adjustment of a blow molding machine, in particular a stretch blow molding machine and, if necessary, also enables the blow molding machine, in particular is an automatic adjustment of the stretch blow molding machine

Embodiment Construction

[0076] figure 1 Shown is a side view of a plastic preform 1 according to the invention. The plastic preform has a base body 2 which can be stretched in a stretching process and a threaded region 4 integrally formed with the base body 2 . The threaded region 4 is not stretched during the stretching. Reference numeral 14 designates a thread lead of the thread of the plastic preform. The plastic preform also comprises a ring body, namely a support ring 6 , which correspondingly has a surface 6 b facing upwards, ie towards the threaded region 4 , and a surface facing downwards, ie towards the base body 2 6a.

[0077] For plastic preforms made of a transparent or at least partially transparent material, most of the light used for inspection passes through the transparent support ring 6 . With a polished support ring, this part of the light passing through the support ring is clearly visible and therefore interferes with the thread or the space at the fixing device. In order to...

Abstract

The invention discloses a machine-readable plastic preform, which comprises a base body, a threaded area disposed on the base body, said threaded area being integrally formed with the base body. An annular section that is annular at least in sections is arranged below the threaded area. The annular section extends outwards in a radial direction of a plastic container, and is integrally formed with the base body. The annular section includes a first surface facing the base body and a second surface facing the threaded area. The base body includes a dome area terminating the same. According to the invention, the plastic preform has a marking that is characteristic of at least one property of the plastic preform. The marking is located on a surface section of the plastic preform. The surface section is located in a longitudinal direction of the plastic preform below the threaded area, and extends at an angle of non-zero in relation to the longitudinal direction of the plastic preform.

Description

technical field [0001] The invention relates to a plastic container blank. Background technique [0002] Such plastic preforms have been known in the prior art for a long time, and they can be formed into plastic containers (eg beverage bottles) by a blow molding process, especially a stretch blow molding process. [0003] Such blow molding machines, such as stretch blow molding machines, are usually operated according to different parameters, such as blow molding parameters. These parameters depend on the plastic container to be molded. Many beverage filling machines and blowing furnaces use various plastic container blanks to manufacture the same container. This leads to parameter adjustments during the blow molding process as well as during the heating process. In some cases, plastic preforms that should not be involved in a particular process still appear in the system. This leads to malfunctions of the production line, especially if a wrong plastic preform is not de...
