FOAM DISPENSING CONTAINER
20200055061 · 2020-02-20 · ·

A foam dispensing container (100) has a container body (40) that reserves a liquid agent (L); a head part (30) that has an outlet (20), and dispenses the liquid agent (L) delivered from the container body (40) through the outlet (20) into foam; and a pump head part (32) that allows dispensing of a predetermined amount of the foamy liquid agent (foam) through the outlet (20) each time it accepts a user's operation. The outlet (20) is formed with a contiguous geometry narrowed from an intended shape. A foam, dispensed through the outlet (20) as a result of a single or multiple operations of the pump head part (32), is built up into the intended shape in a plan view seen in the dispensing direction.

A liquid soap dispenser having a press-type nozzle that dispenses liquid soap from the nozzle by being pressed by hand includes a dispenser body, a nozzle, a pump, and the like. The dispenser body is supported inside an upper storage portion by a lower bracket and an upper bracket. A connecting member connects a vertically moving member and the nozzle. When a user places a hand below the nozzle, a human body detection unit detects the hand, and a control unit causes a motor to rotate in a forward direction and raise the vertically moving member from a lower limit position to an upper limit position; and by raising the nozzle from the lower limit position to the upper limit position via the connecting member, liquid soap is automatically dispensed from the nozzle.

FOAM-AT-A-DISTANCE SYSTEMS AND ANTI-DRIP MECHANISMS FOR SUCH SYSTEMS
20190328181 · 2019-10-31 ·

Exemplary foam-at-a-distance systems include a spout, a container, and a foam generator having a suck-back mechanism located within the spout. The system includes a liquid pump chamber, an air pump chamber, a liquid conduit and an air conduit. The foam generator has a differential bore housing. The differential bore housing has a first portion with a first inside bore and a second portion with a second inside bore, wherein the first inside bore has a smaller diameter than the second inside bore. A piston having a seal extending from the piston that is in contact with the second inside bore is also included. A mixing chamber is located in the large bore. Movement of the seal in an upstream direction provides negative pressure in the second mixing chamber and draws in fluid from the outlet.
