Abstract

The multicomponent cartridge assembly has at least two cartridge containers arranged next to one another and which can be connected to one another via upper and lower connection elements so that they can be plugged together. An additional latch device in the form of interengaging teeth is provided in the region of the upper and/or lower connection elements for the secure holding of the two cartridge containers in the plugged-together state.

Claims

1. A multicomponent cartridge assembly comprising

at least two cartridge containers disposed next to one another;

connection elements disposed in longitudinally spaced apart relation on each of said cartridge containers for interconnecting with respective connection elements on the other of said cartridge containers to connect said cartridge containers together in interconnected relation; and

a latch device in a region of at least one pair of interconnecting connection elements for the secure holding of said cartridge containers in said interconnected relation, each said latch device including mutually corresponding latch tooth arrangements on each of said cartridge containers, each said latch tooth arrangement being configured in the manner of a saw tooth arrangement with teeth having a flatter front side and a steeply falling rear side viewed in the direction of movement of said cartridge containers upon interconnecting together.

2. A multicomponent cartridge assembly in accordance with claim 1 wherein each said cartridge container has a neck at one end thereof having a flat side surface facing a flat side surface on said neck of the other of said cartridge containers and wherein said mutually corresponding latch tooth arrangements are arranged on said respective mutually facing side surfaces.

3. A multicomponent cartridge assembly in accordance with claim 1 wherein the upper connection elements of said connection elements of said cartridge containers are configured for the interconnection of said cartridge containers transversely to the respective longitudinal axes of said cartridge containers and the lower connection elements of said connection elements of said cartridge containers are configured for the interconnection of said cartridge containers in a direction parallel to said longitudinal axes.

4. A multicomponent cartridge assembly in accordance with claim 1 wherein each said upper connection element includes a T-shaped nose at one side of a transverse web and of a T-shaped groove matching said nose at an opposite side of said transverse web.

5. A multicomponent cartridge assembly in accordance with claim 1 wherein each of said lower connection elements includes a connection spigot at a side wall of respective cartridge container and a receiver spaced apart laterally therefrom with a receiver opening matched to receive said connection spigot therein.

6. A multicomponent cartridge assembly in accordance with claim 1 wherein each said cartridge container has a neck at an upper end thereof in the shape of a half-cylinder and having a dispensing opening therein.

7. A multicomponent cartridge assembly in accordance with claim 6 wherein said cartridge necks of said cartridge containers form a cylindrical connection stub for a mixer element.

8. A multicomponent cartridge assembly in accordance with claim 6 wherein each said cartridge neck has a partial thread on an outer side thereof complementary to an external partial thread on the other of said cartridge necks with said cartridge containers in interconnected relation.

9. A multicomponent cartridge assembly comprising

a pair of cartridge containers disposed next to one another;

upper connection elements on said cartridge containers configured for the interconnection of said cartridge containers transversely to respective longitudinal axes of said cartridge containers;

lower connection elements on said cartridge containers configured for the interconnection of said cartridge containers in a direction parallel to said longitudinal axes; and

a latch device in the region of said upper connection elements for the secure holding of said cartridge containers in said interconnected relation, each said latch device including mutually corresponding saw tooth arrangements with teeth having a flatter front side and a steeply falling rear side viewed in the direction of movement of said cartridge containers upon interconnecting together.

10. A multicomponent cartridge assembly in accordance with claim 9 wherein each said upper connection element include a T-shaped nose at one side of a transverse web and of a T-shaped groove matching said nose at an opposite side of said transverse web.

11. A multicomponent cartridge assembly in accordance with claim 9 wherein each of said lower connection elements includes a connection spigot at a side wall of respective cartridge container and a receiver spaced apart laterally therefrom with a receiver opening matched to receive said connection spigot therein.
