Abstract

The present invention relates to an overcap intended for a pharmaceutical container, in particular a container for an infusion solution or an injection solution, having a receptacle containing at least one preproduced closure stopper accommodated therein, the stopper consisting of a soft plastic material, optionally after pulling off a protective covering, for insertion of a withdrawal cannula, a spike and/or a transfer set.

First claim

The invention claimed is:

1. An overcap ( 1 ) intended for a pharmaceutical container for an infusion solution or an injection solution, having a receptacle ( 2 ) containing at least one preproduced closure stopper ( 3 ), the stopper ( 3 ) being introduced from the topside of the receptacle, consisting of a plastic material, for, optionally after pulling off a protective covering, insertion of a withdrawal cannula ( 4 ), a spike and/or transfer set, wherein the complete top surface of said stopper ( 3 ) is exposed, whereby said stopper ( 3 ) is press fitted and weld connected to an inner wall ( 5 ) of said receptacle ( 2 ), said inner wall ( 5 ) has a multi-cylindrical cross-section with at least two different radii, coaxially connected by at least one neck ( 6 ) accommodating the stopper ( 3 ).

2. The overcap ( 1 ) according to claim 1 , characterized in that said stopper ( 3 ) is weld connected to at least one cylindrical circumferential part of the inner wall ( 5 ).

3. The overcap ( 1 ) according to claim 1 , characterized in that said stopper ( 3 ) is weld connected to at least one cylindrical circumferential part of the inner wall ( 5 ) and the at least one neck ( 6 ).

4. The overcap ( 1 ) according to claim 3 characterized in that said weld is achieved by welding of an entire connecting surface between said inner wall ( 5 ) and said stopper ( 3 ).

5. The overcap ( 1 ) according to claim 1 characterized in that said weld is effected so there is no way for the solution to escape from container side to external side.

6. The overcap ( 1 ) according to claim 1 characterized in that at least one line is effected in at least one closed horizontal line, zigzag, meander, stacked closed horizontal lines, grid patterns and combinations thereof.

7. The overcap ( 1 ) according to claim 3 characterized in that said weld is at least one open line, dots, and combinations thereof.

8. The overcap ( 1 ) according to claim 7 , characterized in that at least one open weld line or dots is effected in at least one open horizontal zigzag, meander, spiral, stacked open horizontal lines, vertical noncontiguous lines, random dots, patterned dots and grid patterns or combinations thereof.

9. The overcap ( 1 ) according to claim 3 characterized in that said weld is achieved by laser welding.

10. The overcap according to claim 1 , characterized in it contains at least one membrane ( 7 ) that prohibits the contents of the container from contacting said stopper ( 3 ).

11. The overcap ( 1 ) according to claim 10 , characterized in that said membrane ( 7 ) is an integral part of the receptacle ( 2 ) or a film welded to the receptacle ( 2 ) or a lower part of the overcap ( 1 ).

12. The overcap ( 1 ) according to claim 10 , characterized in that said membrane ( 7 ) is located within an area of the receptacle ( 2 ).

13. The overcap ( 1 ) according to claim 10 , characterized in that the membrane ( 7 ) has a flat form, a dome shaped form or a ripple form.
