A dispenser includes an improved closure arrangement for sealing the dispenser in such a manner that oxidation of the paste-like product to be dispensed is avoided. The main headpiece is spring biased upwardly toward a first position relative to the container and to the product delivery piston, whereupon the upper end surface of the piston is spaced a given distance from the headpiece, and a cylindrical bearing surface on the headpiece closes the product supply outlets contained in the piston. When the main headpiece is depressed downwardly by the given distance toward an intermediate second position in which the headpiece engages the adjacent piston end surface, the bearing surface on the main headpiece is displaced downwardly to open the piston outlets. Upon further downward displacement of both the headpiece and the delivery piston toward a third position relative to the container, the paste-like product is pumped from the delivery chamber by the delivery piston for discharge via a main product outlet contained in the headpiece.

Dispenser for paste-like products

A multi-chamber container comprises a first container for receiving a first product component and a second container for receiving a second product component, the containers being rotationally coupled with one another and each comprising a communication opening for the mutual exchange of the products. Moreover, a closing device is provided for simultaneously closing the two communication openings, the closing device comprising an engaging device for introducing the rotational movement of one container into the closing device, and the closing device further comprising guide devices which are coupled to the other container, such that upon rotational movement the closing device is moved into a position of releasing both communication openings.

Multi-chamber container

The present disclosure relates to a method of filling a dispenser and to the dispenser itself. For already filling a defined part of the head piece (,) when mounting the dispenser after material has been filled into said dispenser and for ensuring an interruption-free dispensing behavior during future operation, it is suggested that, when a first point of airtight sealing of a fluid container (,) by means of a head piece (,) has been reached, the movement of the two elements towards one another should be continued along a predetermined, fixed displacement distance (X). In addition, a dispenser is provided, especially for carrying out the filling method, in which a bottom side of the head piece (,) and a filler opening of the fluid container (,), which is adapted to be coupled to said bottom side, are implemented such that they match.
