Container for surgical soap dispenser
First Claim
1. A container, for holding product to be dispensed from a dispenser, comprising:
- (a) a pair of thin flexible walls in face-to-face position having a top and bottom wherein;
(i) said walls have a first width adjacent their top; and
(ii) a second width less than 30 percent of said first width adjacent their bottom;
(b) said walls being sealed about their perimeter to define a reservoir portion at their top and a depending dispensing leg in communication with said reservoir portion defined by said second width at their bottom; and
(c) a normally closed valve means comprising a plastic clip having a body which surrounds said depending leg and an integrally formed plastic tongue which is cantilevered resiliently from said body and cooperates with said body to pinch a portion of the depending leg between a lip on the distal end of said tongue and said body.

Abstract
An apparatus is disclosed which dispenses a metered quantity of a liquid. The apparatus uses a roller and base pad to form a nip which receives a dispensing leg of a container. Movement of the roller along the base pad causes liquid within the dispensing leg to be dispensed through a pressure responsive valve. The roller travels along a D-shaped path, the straight portion of the path is the nip forming portion. The apparatus operates in response to an object reflecting a beam of electromagnetic energy in the form of infrared light. A container is also disclosed which has a housing, preferably cardboard, and an envelope of flexible plastic contained therein. The envelope holds the liquid and the dispensing leg is accessed through a tear-away opening in the cardboard housing.

8. A container, for holding product to be dispensed from a dispenser, comprising:
-
(a) a pair of thin flat flexible walls in face-to-face position having a top and bottom wherein; (i) said walls have a first width adjacent their top; and (ii) a second width less than 30 percent of said first width adjacent their bottom; (b) said walls being sealed about their perimeter to define a reservoir portion at their top and a depending dispensing leg in communication with said reservoir portion defined by said second width at their bottom; (c) a top marginal portion of said walls defining a pair of openings for receiving pins to suspend said container; (d) a valve means provided adjacent the bottom of said depending leg having lugs for engaging positioning means on a dispenser, and being a plastic clip having a body which surrounds said depending leg and an integrally formed plastic cantilevered resilient tongue having a lip on the distal end thereof which is biased into a position where it cooperates with the body to pinch a portion of the legged closed and said tongue is resilient to bend to an open position in response to an increase in pressure within the depending leg.
