Abstract

A filter covering for a sterile container lid, for completely covering at least one gas exchange portion, which is provided on a lid component of the sterile container lid, on an outside of the sterile container lid, the filter covering having at least two clip portions arranged opposite to each other on the filter covering, which are adapted to engage in a form-fitting manner in at least two clip receiving portions provided on the lid component, and by which the filter covering is mountable to and dismountable from the lid component without tools.

First claim

What is claimed:

1. A filter covering for a sterile container lid, for completely covering at least one gas exchange portion, which is provided on a lid component of the sterile container lid, on an outside of the sterile container lid, wherein the filter covering extends in a main plane, and the filter covering comprises:
at least two clip portions arranged opposite to each other, and
a plate having a height, a length extending in the main plane and a width extending in the main plane, wherein the height is less than the length and less than the width,
wherein the at least two clip portions are formed as portions extending from the plate and bent away from the main plane, and each of the at least two clip portions comprises:
a first end attached to the plate,
a curved surface extending from the first end and defining a bracket-shape or a C-shape having a concave side and a convex side opposite the concave side, and
a second end defining a terminal free edge of the curved surface,

wherein in a sectional view of the filter covering viewed along the main plane in which the at least two clip portions are provided, an entire section of the plate extends in the main plane, and the at least two clip portions bend in a first direction away from the main plane such that the respective concave sides of the respective curved surfaces face one another, and the respective terminal free edges are located closer to each other than respective portions of the respective curved surfaces immediately adjacent to the respective terminal free edges,
wherein a first clip portion of the at least two clip portions comprises a first grip portion projecting in a direction away from the plate, wherein the first grip portion extends from the respective convex side of the first clip portion at a location between and spaced from the respective first end and the respective terminal free end of the first clip portion, and
wherein a second clip portion of the at least two clip portions comprises a second grip portion projecting in a direction away from the plate, wherein the second grip portion extends from the respective convex side of the second clip portion at a location between and spaced from the respective first end and the respective terminal free end of the second clip portion.

2. The filter covering according to claim 1 , wherein the filter covering is made of a plastic material in one piece.

3. The filter covering according to claim 1 , wherein the at least two clip portions are arranged on opposite sides and/or ends of the filter covering.

4. The filter covering according to claim 1 , further comprising one or more supports extending from the plate in the first direction, between the respective first ends of the at least two clip portions, wherein the one or more supports are configured to space the plate from an adjacent surface when the at least two clip portions are positioned to hold the filter covering against the adjacent surface.

5. The filter covering according to claim 1 , wherein the plate is rectangular.

6. The filter covering according to claim 1 , wherein the at least two clip portions consist of exactly two clip portions.

7. The filter covering according to claim 1 , wherein the filter covering is rectangular with a first side, a second side opposite the first side, a third side, and a fourth side opposite the third side, the at least two clip portions being provided on the first side and the second side.

8. The filter covering according to claim 7 , wherein the at least two clip portions are not provided on the third side and the fourth side.

9. The filter covering according to claim 7 , wherein the first side and the second side are shorter than the third side and the fourth side, respectively, and
wherein the first side and the second side each comprise one of the at least two clip portions.

10. The filter covering according to claim 1 , wherein the respective curved surface of the first clip portion extends parallel to the main plane through a respective first distance, the first grip portion extends parallel to the main plane from a respective first end to a respective second end through a respective second distance, and the respective second distance is less than the respective first distance.

11. The filter covering according to claim 10 , wherein the respective curved surface of the second clip portion extends parallel to the main plane through a respective first distance, the second grip portion extends parallel to the main plane from a respective first end to a respective second end through a respective second distance, and the respective second distance is less than the respective first distance.

12. The filter covering according to claim 1 , wherein the first grip portion and the second grip portion extend parallel to the main plane.

13. The filter covering according to claim 1 , wherein the filter covering is made from amorphous thermoplastic and is transparent for visually inspecting a filter device arranged on a lid inner side of a gas exchange portion.

14. The filter covering according to claim 1 , wherein the filter covering is at least partially transparent.

15. The filter covering according to claim 1 , wherein the filter covering is an injection-molded part.

16. The filter covering according to claim 1 , wherein the filter covering is elastically bendable.

17. The filter covering according to claim 1 , wherein the respective terminal free edge of each clip portion is located at a greater distance from the main plane than any other part of the respective clip portion.

18. The filter covering according to claim 1 , wherein a “C” is formed between each of said respective ends of the clip portions and the main plane in the sectional view.

19. The filter covering according to claim 1 , wherein each of said respective curved surfaces immediately adjacent to the respective terminal free edges ends at a downward angle extending away from the main plane and towards an opposite one of the at least two clip portions.

20. The filter covering according to claim 1 , wherein the plate extends in the main plane from a first edge at which a first one of the at least two clip portions is located to a second edge at which a second one of the at least two clip portions is located, and an entirety of the filter covering between the first edge and the second edge extends in the main plane.
