Abstract

A cartridge for an appliance for personal care, such as skin, dental or hair treatment includes a main body (2), a dispensing structure (3, 11, 12) for dispensing a substance, such as a liquid, a paste or a gel, and a cartridge (3) detachably connected to the main body (2). The cartridge bounds a reservoir space (5) for holding the substance to be dispensed and includes: a flexible wall part (7) bounding the reservoir space (5) for allowing reservoir space (5) volume to accommodate to a volume of the substance filled therein and volumes of the substance dispensed therefrom; a rigid wall part (16) also bounding the reservoir space (5), and a rigid housing (6, 14). The flexible wall part (7) is connected to the rigid housing (6, 14) along a contour (23) of the rigid wall part (16).

Claims

1. A cartridge detachably connectable to a main body of an appliance for personal care, such as skin, dental or hair treatment, the cartridge comprising:

a flexible wall part bounding a reservoir space for holding a substance to be dispensed such as a liquid, a paste or a gel, the flexible wall part allowing a reservoir space volume to accommodate to a volume of the substance filled therein,

a rigid wall part also bounding the reservoir space, and

a rigid housing,

wherein the flexible wall part is connected to the rigid housing along a contour of the rigid wall part.

2. A cartridge according to claim 1, wherein a portion of the rigid housing forms at least a portion of the rigid wall part, the flexible wall part being sealed to the rigid housing along a contour of the rigid wall part.

3. A cartridge according to claim 2, wherein at least the outer housing part of the rigid housing is at least partly transparent.

4. A cartridge according to claim 1, wherein the flexible wall part has a shape such that, when the reservoir is in an unfilled condition, the flexible wall part extends closely along the rigid wall part.

5. A cartridge according to claim 4, wherein the rigid wall part has an at least partially concave surface facing the flexible wall part.

6. A cartridge according to claim 1, wherein the flexible wall part is located between the main body and an outer housing part of the rigid housing to which outer housing part it is connected along the contour of the rigid wall part.

7. A cartridge according to claim 1, wherein the flexible wall part is located between an inner housing part and an outer housing part of the rigid housing, to which it is connected along the contour of the rigid wall part.

8. A cartridge according to claim 1, wherein the flexible wall part forms a seal between the inner housing part and the outer housing part along the contour of the rigid wall part.

9. A cartridge according to claim 1, wherein the flexible wall part is clamped between the inner housing part (14) and the outer housing part along the contour of the rigid wall part (16).

10. A cartridge according to claim 8, wherein the rigid housing fully encapsulates the reservoir space.

11. A cartridge according to claim 8, wherein the rigid housing is provided with a passageway for the passage of air to and out of a space within the cartridge between the flexible wall part and the rigid housing.

12. A cartridge according to claim 11, wherein the rigid housing further comprises a closure sealing off the passageway, the closure being at least detachable or perforatable.

13. A cartridge according to claim 1, further comprising a magnetic coupling member for detachably holding the cartridge to the main body of the appliance for personal care.

14. An appliance for personal care, such as skin, dental or hair treatment, comprising a main body, a dispensing structure for dispensing a substance, such as a liquid, a paste or a gel, and a cartridge according to claim 1, the cartridge being detachably connected to the main body.

15. An appliance according to claim 14, wherein at least an outer housing part of the rigid housing forms an outer housing part of the appliance when the cartridge is connected to the main body of the appliance.

16. An appliance according to claim 14, further comprising magnetic coupling members detachably holding the cartridge and the main body together.

17. An appliance according to claim 14, wherein the cartridge comprises at least part of a pump for pumping the substance out of the reservoir space.

18. An appliance according to claim 17, wherein the pump comprises a pumping chamber located between an inner housing part and an outer housing part of the rigid housing and wherein a continuation of the flexible wall part is sealed between the inner housing part and the outer housing part along a contour of the pumping chamber.

19. An appliance according to claim 17, wherein the pump comprises a pumping chamber located between an outer housing part of the rigid housing and a continuation of the flexible wall part and wherein the continuation of the flexible wall part forms a pumping membrane bounding the pumping chamber.
