Abstract: A dispenser head for a pressurized container has a channel for the medium to be dispensed that is connected to a dispensing opening and communicates with the container interior. A closure piston is arranged in the channel and closes off the dispensing opening. By applying pressure onto an actuating element, the valve of the pressurized container is actuated and the closure piston is moved into an opening position to release the dispensing opening. The closure piston has spaced-apart centering projections and flow passages therebetween for the medium. An end face of the closure piston remote from the dispensing opening has an elastic spring area with a head section interacting with the actuating element. The actuating element glides along the rounded head section when the closure piston moves into the opening and closing positions. The rounded head section is matched to the movement path of the actuating element.

Abstract: A dispensing pump implemented as modular functional unit comprises a piston body (10) having a piston section (11) and a cylinder body (20) having a cylinder section (21). The piston section (11) is slidably accommodated in the cylinder section (21). Both said elements define a pump chamber (30) together. An inlet channel (24) and an outlet channel (14) are connected via the pump chamber (30). A respective check valve (31, 32) is arranged in each of said channels (14, 24). Limiting devices (12, 22), which are adapted to be brought into engagement with one another, are provided on said piston body (10) and said cylinder body (20). In addition, a dispenser and a dispenser unit-assembly system are suggested.
