Substance dispensing system
A substance dispensing system comprising in combination:—a disposable container ( 1 ) filled with a portion of a substance, the container having a preformed and deformable body with a bottom ( 2 ), a peripheral wall ( 3 ) adjoining said bottom and having a top end remote from said bottom, an integral circumferential rim ( 4 ) extending outwards from the top end of the peripheral wall and defining a filling opening of said container, said disposable container being closed by a cover sheet ( 5 ) which is sealed to the circumferential rim by means of a circumferential seal ( 6 ), and—a dispensing apparatus ( 30 ) comprising a compression device having a cover sheet side support member ( 15 ) for the cover sheet side of the container as well as a bottom engaging member ( 20 ) for engaging on the bottom of the container, said compression device being adapted to compress the container by reduction of the distance between the cover sheet side support member and the bottom engaging member.
1. A substance dispensing system comprising, in combination:
a disposable container filled with a portion of a substance, the disposable container having a deformable body with a bottom, a peripheral wall adjoining said bottom and having a top end remote from said bottom, an integral circumferential rim extending outwards from the top end of the peripheral wall and defining a filling opening of said disposable container, said disposable container being closed by a cover sheet which is sealed to the circumferential rim by means of a circumferential seal, and
a dispensing apparatus comprising a compression device having a cover sheet side support member for the cover sheet side of the disposable container as well as a bottom engaging member for engaging on the bottom of the disposable container, said compression device being adapted to compress the disposable container by reduction of the distance between the cover sheet side support member and the bottom engaging member,
the cover sheet side support member having a recess therein which is arranged and dimensioned so as extend across a section of the circumferential seal, so that upon compression of the initially closed disposable container the substance therein is pressurized causing the cover sheet to deform into the recess thereby breaking the circumferential seal at said section so that the substance is discharged from the disposable container,
the dispensing apparatus including at least one water pump adapted to provide a portion of water to be dispensed,
the compression device and the water pump being manually driven by a common manual driving device connected to both said compression device and said water pump, said manual driving device comprising:
a lever:
a first transmission connecting the lever to the compression device; and
a second transmission connecting the lever to the water pump.
2. The system according to claim 1 , wherein:
the water pump is a piston pump, and
a single stroke of said piston pump provides the portion of water.
3. The system according to claim 1 , wherein a water dispensing outlet is provided in the cover sheet side support member, in the vicinity of the recess.
4. The system according to claim 1 , wherein the dispensing apparatus includes a cold water pump and a hot water pump, the cold water pump being associated with a cold water circuit and the hot water pump being associated with a hot water circuit.
5. The system according to claim 4 , wherein:
the cold water pump and the hot water pump are manually operable pumps, and
the common manual driving device is selectively engageable with either the hot water pump or the cold water pump.
6. The system according to claim 1 , wherein the dispensing apparatus includes a cold water storage unit associated with a cooling device.
7. The system according to claim 6 , further comprising a water storage container including a dispending connector for selectably connecting the water storage container to the dispensing apparatus.
8. The system according to claim 7 , wherein the cold water storage unit comprises a receiving chamber for receiving the water storage container.
9. The system according to claim 7 , further comprising a pressurized carbon dioxide vessel, and wherein the water storage container includes a carbonation connector for selectably connecting the carbon dioxide vessel to the water storage container.
10. The system according to claim 7 , wherein the water storage container is adapted to contain pressurized carbonated water.
11. The system according to claim 10 , wherein said carbonated water is at a pressure of at least 1.1 bar.
12. The system according to claim 10 , wherein said water storage container includes:
a pressure resistant housing; and
a collapsible bag inside said housing, said collapsible bag being in communication with the dispensing connector and adapted to receive the water.
13. The system according to claim 6 , wherein:
the cold water storage unit includes a reservoir for storage of cold water,
said system includes a user refillable water storage reservoir including a dispensing apparatus connector element,
the dispensing apparatus includes a mating connector element for selectable connection to the connector element of said user refillable water storage reservoir, and
said mating connector element of the dispensing apparatus is in communication with both the reservoir for storage of cold water and a hot water circuit.
14. The system according to claim 13 , wherein the cold water storage unit is connected to both a cold water circuit and the hot water circuit.
15. The system according to claim 1 , wherein said first transmission includes a link.
16. The system according to claim 1 , wherein said second transmission includes a link.
17. The system according to claim 1 , wherein the lever is connected to a pivot and is pivotable around said pivot.
18. The system according to claim 1 , wherein the first transmission includes a gear.
19. The system according to claim 1 , wherein the second transmission includes a gear.
