A dispensing device for a preferably cosmetic liquid as well as a method for the manufacture thereof are proposed. A lasting and tight joining of two materials is achieved while allowing for simple manufacture by pretreating the surface of the first material by means of plasma treatment or irradiation in a desired joining area in order to form radicals there or to break up the polymer chains of the first material, and by then injecting the second material directly against the first material. Another aspect consists in covering the first material with a second material for joining with another material or component.

1. A dispensing device connectable to a container having an interior space, the dispensing device comprising: a housing part configured to connect to the container;a first component connected to the housing part, the first component including a discharge opening spaced apart from a delivery end, the discharge opening configured to be in fluid communication with the interior space of the container; anda second component formed as a valve element injected directly upon at least a portion of the first component and joined to the first component in a joining area that encloses the discharge opening and extends toward the delivery end to define an elongated discharge channel disposed between the first component and the valve element that extends between the discharge opening and the delivery end, wherein the second component is made of an elastically deformable material, wherein the discharge channel elastically opens when a predetermined minimum pressure is exceeded in the discharge opening, wherein the discharge channel automatically closes when the pressure in the discharge opening is below the predetermined minimum pressure to seal the discharge opening and to prevent fluid from being dispensed through the discharge channel,wherein the housing part and the first component are formed as separate parts, wherein the housing part holds the first component swivable or depressible in order to open a delivery valve of the container by the moveable first component, andwherein the joining area is substantially u-shaped. 2. The dispensing device of claim 1, wherein the first component is made of a rigid material. 3. The dispensing device of claim 1, wherein the first component is latched or inserted into the housing part. 4. The dispensing device of claim 1, wherein the first component includes an integral connection part for connecting the first component to a container or valve stem of a container extending substantially perpendicular to the discharge channel and having an internal delivery channel. 5. The dispensing device of claim 4, wherein the discharge opening is formed at an end of the delivery channel. 6. The dispensing device of claim 1, wherein the first component includes a groove, and wherein the valve element engages the groove. 7. The dispensing device of claim 1, wherein the joining area is pretreated to improve the connectability of the first component and the valve element. 8. The dispensing device of claim 7, wherein the joining area is pretreated with at least one of plasma treatment or irradiation. 9. The dispensing device of claim 1, wherein the predetermined minimum pressure is greater than a foaming pressure of a self-foaming liquid. 10. The dispensing device of claim 1, further comprising an actuating element connected to the housing part. 11. The dispensing device of claim 10, wherein the actuating element includes a stop, and wherein when the actuating element is in a non-actuated position, the stop is pressed against the valve element. 12. The dispensing device of claim 11, wherein the actuating element further includes an actuating section and a swivel axis, wherein the swivel axis is positioned between the stop and the actuating section, and wherein the actuating section is configured to act on the first component. 13. A dispensing device, comprising: a housing part configured to connect to a container;a first component including a discharge opening spaced apart from a delivery end; anda second component joined to the first component in a joining area that encloses the discharge opening and extends toward the delivery end to define an elongated discharge channel disposed between the first component and the second component, the discharge channel extending between the discharge opening and the delivery end, wherein at least one of the first component or the second component is made of an elastically deformable material, wherein the discharge channel elastically opens when a predetermined minimum pressure is exceeded in the discharge opening, wherein the elongated discharge channel automatically closes when the pressure in the discharge opening is below the predetermined minimum pressure to seal the discharge opening and to prevent fluid from being dispensed through the discharge channel,wherein the first component is latched into the housing part, wherein the first component is downwards pushable in order to open a delivery valve of the container by the moveable first component, andwherein the joining area is substantially u-shaped. 14. The dispensing device of claim 13, wherein the first component is made of a rigid material. 15. The dispensing device of claim 13, wherein the first component includes an integral connection part extending substantially perpendicular to the discharge channel and having an internal delivery channel. 16. The dispensing device of claim 15, wherein the discharge opening is formed at an end of the delivery channel. 17. The dispensing device of claim 13, wherein the second component is made of the elastically deformable material. 18. The dispensing device of claim 13, wherein the second component is injected directly upon at least a portion of the first component. 19. The dispensing device of claim 13, wherein the first component includes a groove, and wherein the second component engages the groove. 20. The dispensing device of claim 13, wherein the joining area is pretreated to improve the connectability of the first component and the second component. 21. The dispensing device of claim 13, wherein the predetermined minimum pressure is greater than a foaming pressure of a self-foaming liquid. 22. A method for manufacturing a dispensing device for dispensing a liquid, comprising: providing a housing part connectable to a container;providing a first component including a discharge opening spaced apart from a delivery end;providing a second component made of an elastically deformable material;covering at least a portion of the first component with the second component;joining the first component and the second component in a joining area that encloses the discharge opening and extends toward the delivery end to define an elongated discharge channel disposed between the first component and the second component, the discharge channel extending between the discharge opening and the delivery end, wherein the discharge channel elastically opens when a predetermined minimum pressure is exceeded in the discharge opening, and wherein the discharge channel automatically closes when the pressure in the discharge opening is below the predetermined minimum pressure to seal the discharge opening and to prevent fluid from being dispensed through the discharge channel;latching the first component to the housing part;snapping the dispensing device onto a container in order to connect an integral connection part of the first component to a delivery valve of the container, andwherein the joining area is substantially u-shaped. 23. The method of claim 22, further comprising providing an actuating element connectable to the housing part. 24. The method of claim 22, further comprising clamping or snapping on an actuation element. 25. The dispensing device of claim 1, wherein the actuation element is connectable to the housing part by snapping or clamping. 26. The dispensing device of claim 1, wherein upon actuation or depressing of the moveable first element, the valve of the container is opened. 27. The dispensing device of claim 1, wherein the second component or the valve element covers the discharge opening.
