Patent number: 4360130Abstract: The wall-mounted dispenser for liquid soap has a separable reservoir with an outlet valve. The dispenser further includes a main body with a second outlet valve. When the reservoir is mounted to the main body, a metering chamber is defined between the two outlet valves. The dispensing function is experienced by pushing in a plunger which temporarily decreases the chamber volume and forces the main body outlet valve to open temporarily, thus dispensing a charge of liquid soap. As the plunger is released, a spring return pushes the plunger out, decreasing pressure in the metering chamber, which is equalized as the first outlet valve temporarily opens, admitting a next charge of liquid soap from the reservoir to the metering chamber. The reservoir is replaced by pushing in a resilient release, but the resilient release is preferably normally provided with a stop which must first be moved out of the way.Type: GrantFiled: October 15, 1980Date of Patent: November 23, 1982Assignees: Duskin Franchise Kabushiki Kaisha, Kabushiki Kaisha SunpakInventors: Haruo Nishimura, Masaaki Nakaya, Katsuji Nakano, Noboru Matsuda, Noriyuki Matsumoto
