Abstract

A cartridge is configured to be inserted into a meter, the cartridge comprises a housing having an aperture, and end face and a side wall; at least one testing member disposed within the housing; a removable seal; and a knob attached in a fixed positional relationship with the seal, wherein when the seal is in a sealed condition a part of the seal covers the aperture and is secured to the housing around the aperture so as to provide a moisture impermeable barrier and the knob is located adjacent the side wall of the housing.

Claims

1-14. -14. (canceled)

15. A cartridge configured to be inserted into a meter, the cartridge comprising:

a housing having an aperture, an end face and a side wall;

at least one testing member disposed within the housing;

a removable seal; and

a knob attached in a fixed positional relationship with the seal,

wherein when the seal is in a sealed condition the seal is secured to the exterior side wall of the cartridge by a non-permanent adhesive, and a part of the seal covers the aperture so as to provide a moisture impermeable barrier, and the knob is located adjacent the side wall of the housing.

16. A cartridge as claimed in claim 15, wherein the cartridge has a protrusion formed on the sidewall, the protrusion being coincident with the knob when the seal is in the sealed position.

17. A cartridge as claimed in claim 16, wherein the protrusion has a longitudinal axis that extends substantially parallel to a longitudinal axis of the cartridge.

18. A cartridge as claimed in claim 16, wherein the protrusion extends to a position coincident with the junction between the sidewall and the end face of the cartridge housing.

19. A cartridge as claimed in claim 16, wherein the knob is connected to the protrusion by a temporary fixing.

20. A cartridge as claimed claim 16, wherein the knob has a groove formed within a face that faces the sidewall of the cartridge when the seal is in the sealed condition, wherein the protrusion and the groove have complementary cross-sections.

21. A cartridge as claimed in claim 20, wherein the groove has a longitudinal axis that extends substantially parallel to a longitudinal axis of the cartridge.

22. A cartridge as claimed in claim 20, wherein the protrusion and the groove have generally triangular cross-sections.

23. A cartridge as claimed in claim 20, wherein the protrusion and the groove have generally rounded cross-sections.

24. A cartridge as claimed in claim 15, wherein when the seal is in the sealed position an end part of the knob is located coincident with the junction between the sidewall and the end face of the cartridge housing.

25. A cartridge as claimed in claim 15, wherein the knob has a face that slopes downwards from a maximum radial height of the knob in the axial direction parallel to the longitudinal axis of the cartridge towards the location of the aperture.

26. A cartridge as claimed in claim 15, wherein the face that slopes downwards from the maximum radial height of the knob towards the location of the aperture is curved such that it is steeper in the radial direction as the distance from the aperture increases.

27. A cartridge according to claim 15, wherein the seal has a longitudinal axis that extends substantially parallel to a longitudinal axis of the cartridge.

28. A system comprising a meter having a housing and a cartridge as claimed in claim 15, wherein the housing of the meter is configured to allow the cartridge to be inserted therein only after removal of the knob.
