In a foamer dispenser, a depressing head includes: a head main unit with a top wall portion arranged above the stem and with an attachment cylindrical portion that extends downwardly from the top wall portion and is attached to the stem; and an exterior cylindrical portion that is provided beneath the top wall portion and surrounds the attachment cylindrical portion and the guide cylindrical portion from an outer side in a radial direction. An inside of the exterior cylindrical portion is communicable with an inside of the cylinder for air through an inside of the guide cylindrical portion. The head main unit and the exterior cylindrical portion are formed as separate entities and are fitted to each other. In an upper end portion of the exterior cylindrical portion, intake holes are formed that penetrate through the exterior cylindrical portion in a radial direction and open toward an upward direction.

A dispenser assembly for dispensing a product is provided herein. The dispenser assembly includes a bottle configured to store the product, the bottle including a back wall. The back wall includes a substantially flat surface, and an angled surface extending outwards from the flat surface. The dispenser assembly further includes a battery holder including a housing, and a plurality of batteries contained in the housing, wherein the battery holder is positioned adjacent the flat surface of back wall of the bottle and below the angled surface of the back wall.

A pump assembly for generating and dispensing of particles of a solid material with or without dispensing of a fluid. The pump assembly preferably includes a fluid pump which in a cycle of operation draws the fluid through a fluid inlet and dispenses the fluid out a fluid outlet. The pump assembly carries a block of the solid material coalesced together and a rasp member, which during the cycle of operation, moves relative the rasp in engagement with the block whereby the rasp member disengages particles of the solid material from the block which particles drop under gravity downwardly adjacent the fluid outlet, for example, onto a user's hand as in the case that the fluid is a hand cleaning fluid and the solid is a solid soap.

A foam discharge container, including a container main body for accommodating a liquid composition and a foam discharge device which mixes the liquid composition with air and discharges it in a foam form. The foam discharge device has a plurality of porous bodies through which the liquid composition passes when the liquid composition is discharged, the plurality of porous bodies include a tip side porous body arranged in a vicinity of a discharge port of the foam discharge device, and the tip side porous body is composed of polyethylene terephthalate.

The invention discloses an elastic bag foam pump, which comprises a bottle cover (1), an elastic bag (2), a piston rod (3), a piston (4), a liquid inlet one-way valve (6) and a gas inlet one-way valve (8), wherein the elastic bag (2) is a hollow thin-wall bag; the bag opening of the elastic bag is provided with a connection part (2.1); the connection part (2.1) is mounted on an annular wall (1.1) used for connection on the bottle cover (1) in a sealing way; the elastic bag (2) is provided with an inlet hole (1.8) through which an inlet pipe (2.4) is communicated with the bottle cover (1); the gas inlet one-way valve (8) is mounted at one side of the inlet hole (1.8); a piston rod upper end (3.1) is fixed to an upper wall connection part (2.3) of the elastic bag (2); the lower end of the piston rod (3) is provided with the piston (4); and a cylinder (1.2) is arranged in the middle of the bottle cover (1). The elastic bag foam pump has the advantages of simple structure, low cost and easy to use.

An exemplary foam dispenser includes a housing, a drive motor and a foam pump operatively coupled to the drive motor. The foam pump is secured to the housing and the foam pump includes a housing and a molded multi-chamber diaphragm. The molded multi-chamber diaphragm includes a liquid pump chamber, two or more air pump chambers; and an outlet valve.
