Pressurized bag-in-bottle liquid dispensing system
First Claim
1. A fluid dispenser system, comprising:
- a supply bottle including an outer shell having an open mouth and pressure port formed therein at spaced locations, and a deformable inner liner within said outer shell and connected to said outer shell generally at said mouth to permit fluid flow into and from said inner liner through said mouth, said outer shell and inner liner cooperatively defining a pressure chamber therebetween in flow communication with said pressure port;
a supply station for receiving and supporting said supply bottle, and including means for connecting a pressure source via said pressure port to said pressure chamber thereby pressurizing said inner liner and fluid contained therein, said supply station including means for supporting said supply bottle generally at the mouth thereof, and pressure valve means for connecting the pressure source to said pressure chamber;
a delivery conduit connected to said bottle mouth for pressure-caused flow of the fluid from said inner liner; and
dispenser control means for regulating fluid flow through said delivery conduit.

Abstract
A fluid dispenser system is provided for accurate delivery of a viscous or semi-viscous fluid. The dispenser system includes a pressure station for receiving a bottle filled with the selected fluid substance, and for pressurizing the bottle for fluid flow therefrom. In the preferred form, the fluid passes through a metering unit to a dispenser gun having a manually operated trigger. The metering unit responds to trigger operation to deliver a metered volume of the fluid to the dispenser gun for dispensing via a spout. The system is designed for quickly and easily dispensing a rapid succession of accurately metered volumes. The dispenser system is particularly suited for use in dispensing condiments in a fast food restaurant environment, or for dispensing metered volumes of paints and/or pigments used in mixing paints, or for handling other flowable materials such as adhesives and the like.

21. A fluid dispenser system, comprising:
-
a supply bottle including an outer shell having an open mouth and pressure port formed therein at spaced locations, and a deformable inner liner within said outer shell and connected to said outer shell generally at said mouth to permit fluid flow into and from said inner liner through said mouth, said outer shell and inner liner cooperatively defining a pressure chamber therebetween in flow communication with said pressure port; a supply station for receiving and supporting said supply bottle, and including means for connecting a pressure source via said pressure port to said pressure chamber thereby pressurizing said inner liner and fluid contained therein; a delivery conduit connected to said bottle mouth for pressure-caused flow of the fluid from said inner liner; dispenser control means for regulating fluid flow through said delivery conduit; and a metering unit mounted in-line along said delivery conduit and operable for permitting pressure-caused flow of the fluid therethrough in predetermined metered volumes, said dispenser control means being for operating said metering unit;
said metering unit comprising a rotatable core having a generally diametrically extending metering cylinder extending therethrough with a metering piston received slidably within said cylinder, and said control means comprising means for moving said core to a position disposed generally in-line with said delivery conduit whereby fluid within said inner liner is permitted to flow under pressure to said cylinder to displace said piston to a downstream end of said cylinder while filling the residual volume of said cylinder with a metered volume of the fluid, said core moving means including means for rotating said core to reverse the orientation of said cylinder relative to said delivery conduit and thereby move said piston to an upstream end of said cylinder, whereby said metered volume of the fluid within said cylinder is discharged to said delivery conduit for dispensing and a subsequent metered fluid volume is permitted to flow under pressure from said inner liner to said cylinder to again displace said piston to the downstream end of said cylinder. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A fluid dispenser system for use with a supply bottle including an outer shell having an upper end defining a neck with an open mouth formed therein and a lower end having a pressure port formed therein, said supply bottle further including a deformable inner liner within said outer shell and connected to said neck to permit fluid flow into and from said inner liner through said mouth, said outer shell and inner liner cooperatively defining a pressure chamber therebetween in flow communication with said pressure port, said dispenser system comprising:
-
a supply station including a housing having means for receiving and supporting said supply bottle, said housing including a door movable between an open position to permit removable placement of said supply bottle into said housing, and a closed position to prevent access to said supply bottle, pressure valve means for engaging said outer shell at said pressure port and for connecting a pressure source through said pressure port to said pressure chamber when said door is closed, thereby pressurizing said inner liner and fluid contained therein for pressure-caused flow of the fluid from said inner liner through said mouth; and a delivery conduit connected to said bottle neck for flow of the fluid from said inner liner through said delivery conduit. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
