Abstract
A removable batch-type diluent tank for use in connecting to a rigid gas coupling in a beverage dispenser has a tank body for containing a supply of diluent having an opening and a removable cover for covering and sealing the opening. Also included is a relief valve for relieving pressure in the tank prior to removal of the cover. A quick disconnect coupling is rigidly connected to the tank and adapted for sliding connection with the rigid coupling of the dispenser, permitting the tank to be slid into the dispenser for connecting a source of pressurizing gas to the tank. Also included is a connection for conducting diluent from the tank.
Claims24
A removable batch type diluent tank for use in connecting to a rigid gas coupling in a beverage dispenser comprising:
- (a) a tank body for containing a supply of diluent having an opening therein;
- (b) a removable cover for covering and sealing said opening;
- (c) means for relieving pressure in said tank prior to removal of said cover;
- (d) a quick disconnect coupling rigidly connected to said tank and adapted for sliding connection with the rigid gas coupling in said beverage dispenser, whereby said tank may be slid into said dispenser, for connecting a source of pressurizing gas to said tank;
- and
- (e) means for conducting diluent from said tank.
A batch type diluent tank for use in a beverage dispenser comprising:
- (a) a tank body for containing a supply of diluent having an opening therein and having a recessed opening in the top thereof;
- (b) a bore at the bottom of said recessed opening;
- (c) a cover containing a cylindrical portion for covering and sealing said opening, said bore and cover including means for bringing them into and retaining them in sealing engagement;
- (d) a means disposed in said cover for relieving pressure in said tank prior to removal of said cover;
- (e) mechanical means to operate said means for relieving pressure;
- (f) a cutout in the top of said tank body, said means to operate adapted to fit in said cutout such that said cover cannot be unscrewed until said means to operate is moved to relieve the pressure in said tank;
- and
- (g) means for connecting a source of pressurizing gas to said tank and for conducting diluent from said tank.
A diluent tank for use in a beverage dispenser comprising:
- (a) a tank body for containing a supply of diluent having a threaded opening therein;
- (b) a threaded cover for covering and sealing said opening;
- (c) means for relieving pressure in said tank prior to removal of said cover;
- (d) means for connecting a source of pressurizing gas to said tank and for conducting diluent from said tank;
- and,
- (e) means for preventing said cover from being fully removed from said body upon removal of said cover by rotation until after, the seal between said cover and body is broken, whereby if said means for relieving pressure fails, gas can escape without having said cover blow off.
A removable batch type diluent tank for use in a beverage dispenser comprising:
- (a) a tank body for containing a supply of diluent having an opening therein;
- (b) a removable cover for covering and sealing said opening;
- (c) means for relieving pressure in said tank prior to removal of said cover;
- (d) mechanical interlock means for preventing removal of said cover until said means for relieving pressure are operated;
- (e) a quick disconnect coupling for connecting a source of pressurizing gas to said tank;
- and
- (f) means for conducting diluent from said tank.
A removable batch type diluent tank for use in a beverage dispenser comprising:
- (a) a tank body for containing a supply of diluent having an opening therein;
- (b) a cover removable by rotation for covering and sealing said opening;
- (c) means for supplying a pressurizing gas to said tank and means for removing diluent from said tank;
- (d) means for relieving pressure in said tank prior to removal of said cover;
- (e) mechanical interlock means for preventing removal of said cover until said means for relieving pressure are operated;
- and
- (f) means for preventing said cover from being fully removed from said body upon rotation of said cover until pressure within said tank is below a predetermined amount whereby, if said means for relieving pressure fails, gas can escape without having said cover blow off.
