Abstract
A device for discharging cream or paste like material from a container, comprising a treat-like sleeve of a resilient material which has a mechanism for securing on an outlet on the container. The sleeve is intended for being provided in a depending position on the container. Inside the sleeve in the upper portion a body is provided, which is designed to be forced towards the container in case of an increase of pressure in the cream or paste-like material in the sleeve, and which is, via an elongated member, connected with the valve member at the lower end of the sleeve, the valve member cooperating with a discharge opening at the lower end of the sleeve. The body is dimensioned to be guided by the container outlet or another opening connected to the latter. A passage is provided through the body with an outlet opening inside the sleeve. A check valve is provided inside or near the channel or the passage. In a preferred embodiment the channel or passage is provided centrally in the body and cooperates with a channel or passage in the elongated member, and the outlet is then provided in a side wall of the elongated member.
