A dispenser for pasty compositions, having a housing with a piston which is displaceable only in the emptying direction and an actuating handle on the outside by which action can be effected on a pump element which can be depressed in the direction of the piston. The pump element has an inlet valve and an outlet valve, the outlet valve being arranged in the actuating handle, the outlet valve being furthermore spring-urged into its closed position by means of spring elements which are developed thereon and extend into the inside of the dispenser. This provides for an embodiment which is simple to manufacture and advantageous in use. The spring elements are developed as spring legs which are formed free standing directly on a valve plate and rest against a collar of the actuating handle.

Dispenser for pasty compositions

This invention is directed to a flap valve for a dispenser for viscous fluids. More particularly, this invention is directed to a flap valve having a body with a cylindrical valve opening therein, produced by injection molding which is circularly symmetrical to the cylindrical valve opening and extends outwardly around the axis of symmetry, wherein at least one spoke bridges the valve opening diametrically and has a sprue wart in the center thereof, said body cooperating with a flap which closes said cylindrical valve opening, the center part of which flap is arched away from the sprue wart out of the plane of its edge, which edge sealingly fits over the edge of said cylindrical valve opening.

Flap valve for a dispenser

This invention is directed to a dispenser for viscous fluids. More particularly, this invention is directed to a dispensing container comprising a container body provided at one end with a resiliently compressible portion including a mouthpiece; a storage chamber to hold material to be dispensed; piston member arranged at the other end of said container to define a boundary of the storage chamber, the piston member being movable towards and restrained from movement away from said compressible portion; a top surface to define another boundary of the storage chamber; and an elastically compressible pump having an inlet valve in the top surface, an outlet valve, and a pump chamber between the valves, said inlet valve comprising an annular slot extending circularly in the top surface symmetrically to the longitudinal axis of the container and a circular cover ring hold sealingly in front of the annular slot and elastically under constant stress, the cover ring being held by three or more spokes radiating from a hub positioned in the center of the top surface.
