"Paste dispenser"

The invention relates to a paste dispenser for coupling to a paste container with a piston-cylinder arrangement for the dosed pressing of the paste, in which the piston drive and the container are mounted in the dispenser body is designed as a cylinder of the piston.

In such dispensers of the type that has been customary up to now, a spindle to be rotated is used as the piston drive. Since that Rotation relative to the dispenser body is a one-handed operation for dispensers with a spindle and piston not possible.

In the case of one-hand dispensers for pastes that have already been used in practice, the paste is removed from the respective Container uses either a pump or an attached flexible bellows. There are also so-called "Press-Pack-Dosen" applied. Here, a rubber-like bellows provided as a paste container is inserted into a brought airtight can. After filling the bellows

the can maintains an internal pressure so that product can be removed from the container by actuating a valve is. However, these dispensers are either too short to manufacture or not always functional when used.

The invention is based on the object of further developing the paste dispenser mentioned at the beginning so that safe one-handed operation is to be ensured without excessive manufacturing effort. The inventive The solution is the piston-cylinder arrangement with a piston drive mounted in the dispenser body and as a cylinder of the piston formed container characterized by a container space to be pressed out facing away piston surface to be brought up, with the hand grasping the dispenser body to be operated rack as a one-hand piston drive.

The invention achieves that the fasting donor without the use of complex pump or gas pressure elements in a form-fitting to be designed as an additional pack It is to be produced and used as a one-hand dispenser. Under the rack according to the invention is to be understood as a piston feed rod with a "rough" surface in the broadest sense. In the simplest case the rod can thus be designed so that it is directly inclined to its rough surface by means of The pressure exerted on the longitudinal axis is to be pushed forward with the aid of a finger.

However, it is preferably used to remove product from the donor to one stored in the donor body and

That said c gear can with advantage also by a mounted in the dispenser body and operated from the outside Lever mechanism can be replaced as a rack and pinion drive. In any case, the rack should be inside the dispenser body be stored in such a way that a secure positive coupling to the rack and pinion drive is guaranteed is. The rack is therefore preferably guided in a guide mounted in the dispenser body, All components should expediently be designed so that the container containing the respective paste and the Piston drive problem-free and safe, for example advantageously with the help of a between the dispenser body and the container provided circumferential screw connection.

Further details of the invention are explained using the schematic representation of an exemplary embodiment. Show it:

1 to 3, an embodiment of a paste dispenser according to the invention is shown schematically in longitudinal and cross-section and in an external view. The paste dispenser consists of a paste container denoted as a whole by 1 and a dispenser body denoted as a whole by 2. At the end provided for the exit of the paste 3, the container 1 has an exit opening H- which is to be covered with the aid of a closure 5. At the end of the container 1 facing the dispenser body 2, a coupling is provided for securely connecting the two elements. In the exemplary embodiment, the coupling is designed as a circumferential screw connection 6.

The dispenser body 2 is preferably given di <on its outer surface. Shape of a handle 7

ter 1 to be inserted piston 8 be arranged. According to the invention, the piston is provided with the aid of a toothed rack 9 to be actuated in the direction of arrow 10 in container 1. The outer circumference of the piston 8 and that perpendicular to the longest. Axis 11 running clear cross-section of the container 1 are to be adapted to each other so that the paste 5 through Forward sbev / egen of the piston 8 in the direction of the arrow 10 from the outlet opening 4 (with the closure 5 lifted) the container 1 is to be squeezed out. In order to ensure a safe and tilt-free advance of the piston 8, the rack 9 driving the piston 8 is to be mounted in a sufficiently stable manner within the handle 7 be that they can only be moved in the direction of the common longitudinal axis 11 of container 1 and dispenser body 2 is. In the exemplary embodiment, a guide 12 is provided for the corresponding guidance of the rack 9. This can be at the longitudinal ends of the handle 7 up to the base parts 13 (these parts are only on a longitudinal end of the handle 7 drawn) are stored stably.

In the exemplary embodiment, a toothed wheel 14 is used to drive the toothed rack 9. This should be rotatable and an axis. 15 are stored in the dispenser body 2.

The preparation of an F.ohalter is shown on the basis of FIGS. 4 to 6 1 explained. The container 1, which is provided with a closure 5 covering the outlet opening 4, is of the side opposite the outlet opening 4 is initially filled with paste 3. Then kr.nn der Piston 8 inserted into container 1 and then diorer with a cap 16, for example taking advantage of the Circumferential lettering 6, can be locked. In this

The container is ready for dispatch as a replacement pack.

When using the paste container 1 is from this after l ^? ig. 7 to 9, the cap 16 is first removed, then the dispenser body 2 'is screwed onto the container 1 in the area of the circumferential screw connection 6, so that the toothed rack 9 engages with the side of the piston 8 facing away from the paste 3 in the central area 17 provided bring is. When required and after the closure 5 has been ^{removed, paste 3 can be pressed out of the container 1 by actuating the gear 1 z} l- in the direction of the arrow 18 (FIG. 7). After the container 1 has been completely emptied (FIG. 8), it is removed again from the dispenser body 2 (FIG. 9) and the rack 9 is pushed back into the handle 7 in the direction of arrow 19.

Instead of the gear 14, any other means for positive coupling and driving can of course be used of the rack 9, for example a lever mechanism, can be used.
