Abstract
Abstract A disposable liquid testing device consisting essentially of a cup-shaped container, wherein the container (2) is provided with an outer cup (3) to be sealingly placed and axially (4) fixed on the bottom part (4) of the container, which outer cup can be put in at least two coplanar end positions relative to the container (2), the bottom (5) of the container (2) is provided with at least one liquid passage (6) and at least one reagent (7) is applied on the side of said bottom (5) facing the outer cup (2), and the bottom (12) of the outer cup (3) comprises at least one reservoir (8) which is in register with the liquid passage (6) in one end position of the outer cup (3) and in register with the reagent (7) in the other end position. <IMAGE>

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
168 words
A disposable liquid testing device consisting essentially of a container having a side wall and a bottom wall on a lower end of said side wall, and an outer cup having a side wall and a bottom wall on a lower end of said cup side wall sealingly placed and axially fixed on the lower end of the side wall, said outer cup being rotatable such that said outer cup can be put in at least two coplanar end positions relative to the container, the bottom wall of the container is provided with at least one liquid passage therethrough and at least one reagent is applied on a lower surface of said bottom wall facing the outer cup, and the bottom wall of the outer cup abuts against the bottom wall of the container and comprises at least one reservoir which is in the register with the liquid passage in one end position of the outer cup and in register with the reagent in the other end position.
Claim 2
Dependent Claim
168 words
A disposable liquid testing device consisting essentially of a container having a side wall and a bottom wall on a lower end of said side wall, and an outer cup having a side wall and a bottom wall on a lower end of said cup side wall sealingly placed and axially fixed on the lower end of the side wall, said outer cup being rotatable such that said outer cup can be put in at least two coplanar end positions relative to the container, the bottom wall of the container is provided with at least one liquid passage therethrough and at least one reagent is applied on a lower surface of said bottom wall facing the outer cup, and the bottom wall of the outer cup abuts against the bottom wall of the container and comprises at least one reservoir which is in the register with the liquid passage in one end position of the outer cup and in register with the reagent in the other end position.
