Abstract: A foam dispenser utilizing components made from the same or similar materials that can be recycled in a single recycling process or stream includes a plastic spring system acting on spring cones formed in a piston rod and an accumulator, an air valve having multiple flanges to facilitate the flow of air into and out of the foam dispenser, and a liquid piston configured to improve the control of liquid flow through the foam dispenser and which is more easily manufactured.

Abstract: Manually operated dispenser for media, with a reservoir (1), with a pump part (2) which is mounted on the reservoir (1) and comprises a nozzle-shaped discharge portion (3) with a discharge portion end (5) having a discharge opening (4), with an actuation mechanism (6) assigned to the pump part (2), and with a protective cap (7) covering at least the discharge portion end (5), wherein a soft porous insert (8) is inserted into the protective cap (7) and can be pressed when the protective cap (7) is fitted from above onto the discharge portion end (5), and the discharge portion (3) forms a stand surface (9) for a free end (10) of a torsion spring (11), which is clamped in the protective cap (7) and whose loading introduces a torque that turns the protective cap (7) relative to the discharge portion (3).
