Abstract

For dispensing liquids, a disposable bottle having inherently resilient, easily penetrable plastic walls and a capped mouth that is separably inserted into a rigid receptacle in which are mounted fixed bottle piercing devices that also serve respectively as an outlet for the liquid contents of the bottle and as an inlet for propellant gas under low pressure of the order of 3 pounds, said receptacle having key guide ribs to mate with corresponding recesses in the bottle to permit insertion of bottles of only one and the same design into the receptacle, and preferably, the second-mentioned piercing device being located in one of said ribs to penetrate the bottle wall during such insertion of the bottle.

Claims

1. A liquid dispensing apparatus comprising a liquid container having inherently resilient easily penetrable wall portions, a receptacle to removably receive said container, a pair of container piercing devices fixedly mounted in said receptacle and formed to serve respectively as an outlet for the container contents and as an inlet for propellant gas under pressure, at least one piercing device being located in said receptacle to provide for penetration of the container wall portion by said piercing device when one end portion of the container is pressed into the receptacle against said piercing device, said container having a longitudinal guide recess opening outwardly at the side and one end of said end portion of the container, and said receptacle having an inwardly projecting key guide rib with which said recess is required to mate to permit insertion of the container into the receptacle, and wherein said one piercing device is located on said guide rib.

2. A liquid dispensing apparatus comprising a plastic liquid container having easily penetrable resilient wall portions, a rigid receptacle to removably receive said container, a pair of container piercing devices fixedly mounted in said receptacle and formed to serve respectively as an outlet for the container contents and as an inlet for propellant gas under pressure, said piercing devices being located in said receptacle to provide for penetration of said penetrable wall portions by said piercing devices simultaneously, when the container is pressed into the receptacle against said piercing devices, each piercing device having a base rigidly associated with the receptacle, a stud having a hole therethrough and one end separably connected to said base and its other end provided with a conical piercing point, a cylindrical portion of reduced diameter and a frusto-conical portion between said piercing point and said reduced cylindrical portion providing for sealing engagement of said cylindrical and frusto-conical portions with the resilient edge portions of the punctures in the container walls formed by said piercing devices, the inherent resiliency of said edge portions of the punctures and the pressure in the container pressing said edge portions into tight sealing engagement with said frusto-conical portions and said cylindrical portions, and wherein said container has a longitudinal recess opening outwardly at the side and one end of the container, and said receptacle has a key guide rib with which said recess is required to mate to permit insertion of the container into the receptacle and wherein the second-mentioned piercing device is mounted on said guide rib.

3. A liquid dispensing apparatus comprising a liquid container having inherently resilient easily penetrable wall portions, a receptacle to removably receive said container, a pair of container piercing devices fixedly mounted in said receptacle and formed to serve respectively as an outlet for the container contents and as an inlet for propellant gas under pressure, at least one piercing device being located in said receptacle to provide for penetration of the container wall portion by said piercing device when one end portion of the container is pressed into the receptacle against said piercing device, said container having a longitudinal guide recess opening outwardly at the side and one end of said end portion of the container, and said receptacle having an inwardly projecting key guide rib with which said recess is required to mate to permit insertion of the container into the receptaclE, and wherein said receptacle has a bottom wall and an annular side wall providing an opening at its upper end to receive said container, said guide rib extends inwardly from said side wall and has an end portion facing said open upper end, said recess in the container has an inner end wall adapted to be disposed opposite said end portion of the rib when the container is inserted into the receptacle, and said one piercing device is mounted on said end portion of the rib to pierce said end wall of said recess when the container is pressed into the receptacle.
