Moulding suitable for pharmaceutical applications and method for production thereof
First Claim
1. Moulding serving for pharmaceutical uses, such as a stopper (1) for pharmaceutical bottles, a protective cap (2) for medical syringes or a sealing element (38, 39) for pharmaceutical containers, the moulding (1, 2, 38, 39, 44) consisting, at least in a subregion, of a thermoplastic elastomer material with a mineral filler content of 30% or more and this subregion having a hot-runner injection point which is formed as a smooth-surfaced mark.

Abstract
The invention relates to a moulding serving for pharmaceutical uses, such as a stopper (1) for pharmaceutical bottles, a protective cap (2) for medical syringes or a sealing element (38, 39) for pharmaceutical containers, and proposes, to achieve production with virtually no scrap and with high product quality, that the moulding (1, 2, 38, 39, 44) consists, at least in a subregion, of a thermoplastic elastomer material with a mineral filler content of 30% or more and this subregion has a hot-runner injection point which is formed as a smooth-surfaced mark.

- 1. Moulding serving for pharmaceutical uses, such as a stopper (1) for pharmaceutical bottles, a protective cap (2) for medical syringes or a sealing element (38, 39) for pharmaceutical containers, the moulding (1, 2, 38, 39, 44) consisting, at least in a subregion, of a thermoplastic elastomer material with a mineral filler content of 30% or more and this subregion having a hot-runner injection point which is formed as a smooth-surfaced mark.
- 2. Moulding serving for pharmaceutical uses, such as a stopper (1) for pharmaceutical bottles, a protective cap (2) for medical syringes or a sealing element (38, 39) for pharmaceutical containers, the moulding (1, 2, 38, 39, 44) consisting, in a subregion, of a thermoplastic elastomer material with a mineral filler content of 30% or more and this subregion having an injection point, which is injected over by a second part of the moulding, consisting of another plastics.
-
13. Moulding according to one of more of the preceding claims or in particular according thereto, characterized in that the thermoplastic elastomer material contains a proportion of plasticizers.
-
16. Protective cap (2) produced in the plastics injection-moulding process for medical syringes, with a solid cap hat (18) and a comparatively thin-walled cap neck (19), characterized in that the protective cap (2) consists of thermoplastic elastomer material with a mineral filler content of 30% or more and in that there is a hot-runner injection (A) in the region of the cap hat (18).
-
19. Method for producing a moulding for a pharmaceutical use, such as a stopper (1) for pharmaceutical bottles, a protective cap (2) for medical syringes or a sealing element (38, 39) for pharmaceutical containers, characterized in that the moulding is produced, at least in a subregion, from a thermoplastic elastomer material with a mineral filler content of 30% or more and this subregion is configured by a hot-runner injection, the injection point being formed as a smooth-surfaced mark.
- 20. Method for producing a moulding for a pharmaceutical use, such as a stopper (1) for pharmaceutical bottles, a protective cap (2) for medical syringes or a sealing element (38, 39) for pharmaceutical containers, characterized in that the moulding is produced, in a subregion, from a thermoplastic elastomer material with a mineral filler content of 30% or more and this subregion is configured by an injection having an injection point, which injection point is injected over with another plastics, forming a second subregion of the moulding.
- 26. Method for producing a stopper (1) for pharmaceutical bottles (3), such as for example infusion bottles, in the plastics injection-moulding process, with a stopper top (13) and a stopper collar (14), characterized in that a thermoplastic elastomer material with a 30% or more admixed mineral filler content is used and in that a central hot-runner injection (A) is performed in the region of the stopper top (13) of the stopper (1) of a predominantly thick-walled form.
- 29. Method for producing a protective cap (2) for medical syringes in the plastics injection-moulding process, with a solid cap hat (18) and a comparatively thin-walled cap neck (19), characterized in that a thermoplastic elastomer material with a 30% or more admixed mineral filler content is used and in that a central hot-runner injection (A) is performed in the region of the cap hat (18).
