Problems solved by technology

The main disadvantage of this known device is that, once sprayed, the disinfecting liquid enters under the action of ultraviolet radiation, so that the disinfectant reaching the container is already partially denatured, and large quantities of liquid have to be dispensed, which also increases costs

Embodiment Construction

[0028] Figure 1 schematically shows a parison-feeding plant A, which represents the input unit of a plant B, which manufactures thermoplastic containers by blow molding or stretch blow molding.

[0029] A conventional construction of a feeding device consists of a hopper 1 into which parisons made of thermoplastic material such as PET are poured loosely, from the bottom of which the parisons are sequentially removed by a lifting device 2 and lifted The device is lifted to a positioning device 3 which positions the parisons, erected one after the other, with the neck on top.

[0030] After the parison 4 moves out of the positioning device 3, the parison moves to the inclined slideway 5, and slides down successively by gravity. The slideway 5 is conventionally formed by two parallel rails spaced apart from each other. The parison is supported astride the top of these two rails by means of an external collar at the bottom of the parison neck, while the parison body is fitted and...

Abstract

The invention concerns decontamination of the neck of thermoplastic performs (4) designed for making containers through a blow forming or extrusion blow molding process, when feeding (in A) the performs (4) sequentially into a unit (B) for manufacturing containers, which consists in passing the neck of the performs (4) through a mist (in 9) of a decontaminating product, then in subjecting the neck of the performs (4) wetted by the decontaminating products to the action of an ultraviolet radiation (in 7) for a least a predetermined minimum time interval.

Description

technical field [0001] The present invention relates generally to the field of decontamination (or reduction of soiling levels) of thermoplastic (particularly PET) parisons, which are used to make containers such as bottles, by blow molding or stretch blow molding, and More particularly, the invention serves to improve the purification steps of these parison necks. Background technique [0002] For the decontamination of non-thermoplastic containers, it is known to decontaminate the parison at the beginning of the container manufacturing process, rather than decontaminating the finished container at the end of its manufacture, in order to greatly reduce the amount of decontamination used (the Amount is a function of the surface area to be treated). [0003] As an example, document FR-A-2766121 discloses a method and apparatus for decontamination of parisons, comprising wetting the parisons by immersing them in a decontamination vat such as hydrogen peroxide, and then by hea...
