Abstract: A dispenser for flowable media is provided, which operates in user-independent manner with respect to the pressure buildup and dosage quantity. On pressing on an operating head (35) a piston rod (29) is forced into a pump cylinder. As the pump chamber (52) is sealed by means of a delivery valve (51), which operates in path-dependent manner as a slide valve, under the action of a spring (42) pressing on the piston collar (43), a pressure builds up in the pump chamber (52), which is released following a predetermined length of travel on opening the delivery valve. A relatively constant pressure can be obtained over the entire discharge phase through the pretension of spring (42).

Abstract: A valve body has one or more integral seal retention grooves and one or more interior hollows which may be manufactured using frictional or other types of welding to join two previously formed portions through at least one cylindrical web. Forging or casting valve body portions to near-net-shape prior to joining minimizes machining necessary to achieve a final desired shape. One or more interior hollows and an integral seal retention groove are formed in the welded valve body from features present on the portions joined by welding to form the body. Increased valve durability and reduced metal wear arise from the reduced valve body weight and correspondingly reduced impact loading. An elastomeric seal may be cast and cured in place in a seal retention groove.

Abstract: An assembly for packaging a product such as a cosmetic product in the form of a cream or a gel. The assembly includes a flexible container or pot containing the product, with the container having a first end closed by a bottom and a second end, opposite the first, forming a neck delimiting an opening. The flexible container is removably disposed in a rigid structure with the rigid structure preferably extending substantially over the entire height of the container lying under the neck. The flexible container is configured so that, once it is extracted from the rigid structure, pressure exerted on the flexible container causes deformation of the container to displace the product towards the opening for use. The container can return to its undeformed shape by elastic return forces when the pressure ceases.
