Abstract: A cover for a valve handle comprises an elongate base including a front side and a rear side, a protrusion for being inserted into a corresponding hole of the valve handle. The protrusion projects from the rear side of the base. A retaining element extends opposite to the rear side and is fixed to the base. The base and the retaining element together define a receiving space including an opening for receiving a free end of the valve handle. The opening is located at a distance from the protrusion in longitudinal direction of the base and directed to the protrusion.

Abstract: A filter for a vent opening of a container comprises a filter element and a flange which surrounds the filter element. The filter element and the flange are integrated by means of an injection molding process, in which material is injected against a solid filter element in a mold, from which material the flange arises after curing. The filter element has an edge portion which extends in its circumferential direction. The edge portion has a front side, a back side and a side edge extending between the front side and the back side. The back side is covered the flange and the side edge in circumferential direction of the edge portion is alternatingly entirely and partly covered from the back side by the material of the flange. At the locations where the side edge is entirely covered the front side is also covered by the material of the flange.
