Abstract

A fluid dispenser for the foodstuff supply sector has a dimensionally rigid housing ( 1 ) with viscous contents, wherein the fluid dispenser is designed to receive tubular bags which have a dispensing device ( 7 ) that is fitted or can be fitted on the tubular bag ( 2 ) itself and that permits metered dispensing of the contents. Moreover, the tubular bag ( 2 ) can be inserted and secured in a predetermined position in the fluid dispenser, and an auxiliary device is present with which the viscous contents located in the tubular bag can be continuously pushed in the direction of the dispensing device ( 7 ) on the tubular bag, by mechanical application of pressure to the tubular bag ( 2 ) in the position of use of the fluid dispenser. To secure the tubular bag ( 2 ) in the housing ( 1 ), a clamping device is present. The auxiliary device is a weighting roller ( 3 ) which is mounted between two lateral guides ( 5 ) in the housing ( 1 ) and which, in the position of use of the fluid dispenser, bears horizontally on the tubular bag ( 2 ) and, by means of its inherent weight, is able to push the viscous contents of the tubular bag continuously to the dispensing device ( 7 ) on the tubular bag. The auxiliary device additionally contains position-stabilizing means with which the horizontal bearing of the weighting roller on the tubular bag, in the position of use of the fluid dispenser, can be stabilized.

First claim

The invention claimed is:

1. A fluid dispenser for the foodstuff supply sector comprising a dimensionally rigid housing ( 1 ) configured to receive a tubular bag ( 2 ) with viscous contents, wherein the tubular bag has a dispensing device ( 7 ) that is fitted or can be fitted on the tubular bag ( 2 ) and permits metered dispensing of the contents, and wherein the tubular bag ( 2 ) can furthermore be inserted and secured in a position in the fluid dispenser, an auxiliary device with which the viscous contents located in the tubular bag can be continuously pushed in the direction of the dispensing device ( 7 ) on the tubular bag, by mechanical application of pressure to the tubular bag ( 2 ) in the position of use of the fluid dispenser, and a clamping device configured to secure the tubular bag ( 2 ) in the housing ( 1 ), wherein the auxiliary device is a weighting roller ( 3 ) which is mounted between two lateral guides ( 5 ) in the housing ( 1 ) and which, in a position of use of the fluid dispenser, bears horizontally on the tubular bag ( 2 ) and, by means of inherent weight of the roller, is able to push the viscous contents located in the tubular bag continuously to the dispensing device ( 7 ) on the tubular bag, characterized in that the auxiliary device contains position-stabilizing means with which the horizontal bearing of the weighting roller on the tubular bag, in the position of use of the fluid dispenser, can be stabilized; wherein the clamping device is configured to achieve a three point clamping for the tubular bag ( 2 ) having two upper clamping means ( 6 a , 6 b ) in the position of use and one lower clamping means ( 6 c ) in the position of use, wherein the lower clamping means is a holder for the dispensing device ( 7 ) that is fitted or can be fitted on the tubular bag ( 2 ), characterized in that at least one of the upper clamping means ( 6 a , 6 b ) is adjustable so as to vary the distance to the other upper clamping means ( 6 b , 6 a ).

2. The fluid dispenser according to claim 1 , characterized in that the position stabilization means include toothed racks in the guides ( 5 ) and gear wheels ( 9 ) that interact with the toothed racks on the end faces of the weighting roller ( 3 ).

3. The fluid dispenser according to claim 1 , characterized in that the position stabilization means include conical grooves in the guides ( 5 ) and guide wheels with conical wheel edge formation, which interact with the conical grooves, on the end faces of the weighting roller ( 3 ).

4. The fluid dispenser according to claim 1 , characterized in that the weighting roller ( 3 ) has an elongated cylindrical core ( 10 ) and an elastic sheathing ( 11 ) that surrounds the core ( 10 ) like a cylinder jacket.

5. The fluid dispenser according to claim 4 , characterized in that the elastic sheathing ( 11 ) consists of a foam having a sheathing layer thickness of 6-10 mm.

6. The fluid dispenser according to claim 1 , characterized in that the housing has two parts and is configured to be folded open.

7. The fluid dispenser according to claim 1 , characterized in that the housing ( 1 ) is configured to be inserted in a base unit ( 12 ) or set on the base unit.

8. The fluid dispenser according to claim 1 , characterized in that the upper clamping means ( 6 a , 6 b ) in the position of use include gripping means.

9. The fluid dispenser according to claim 1 , characterized in that the upper clamping means ( 6 a , 6 b ) are obliquely offset with respect to the housing ( 1 ) in order to achieve an oblique position of the inserted tubular bag ( 2 ) in the range of 4-6 angular degrees.

10. The fluid dispenser according to claim 1 , characterized in that the holder is configured for dispensing devices such as metering pumps, push-in or rotary closures.

11. The fluid dispenser according to claim 1 , characterized in that the fluid dispenser is configured for receiving standardized, substantially rectangular tubular bags ( 2 ), which comprise a volume range of 1 liter to 12 liters.
