Abstract

Apparatus (2) for testing a liquid specimen, which apparatus (2) comprises: (i) a container (4) for the liquid specimen; (ii) a lid (6) for closing the container (4) after the liquid specimen has been provided in the container (4); (iii) first securing means (8) by which the lid (6) is secured to the container (4); (iv) a test capsule (10) for securing to the lid (6) when the lid (6) is on the container (4); (v) second securing means (12) by which the test capsule (10) is secured to the lid (6); and (vi) a response chart (14) which is operable in response to contact with the liquid specimen, and the apparatus (2) being such that: (vii) the lid has an openable portion (18) which when opened permits a liquid specimen in the container (4) to enter the test capsule (10); (viii) the test capsule (10) has opener means (20) for opening the openable portion on the lid (6) when the test capsule (10) is secured to the lid (6); and (ix) the response chart (14) is inside the test capsule (10) and is contacted by the liquid specimen when the liquid specimen enters the test capsule (10).

Apparatus An apparatus for testing a liquid specimen, which apparatus comprises:

(i) a container for the liquid specimen;
(ii) a lid for closing the container after the liquid specimen has been provided in the container;
(iii) first securing means by which the lid is secured to the container;
(iv) a test capsule for securing to the lid when the lid is on the container;
(v) second securing means by which the test capsule is secured to the lid;
and
(vi) a response chart which is operable in response to contact with the liquid specimen,;
the apparatus being such that:
(vii) the lid has an openable portion which when opened permits a liquid specimen in the container to enter the test capsule;
(viii) the response chart is inside the test capsule and is contacted by the liquid specimen when the liquid specimen enters the capsule;
(ix) the test capsule has opener means for opening the openable portion on the lid;
and the apparatus being characterised characterized in that:
(x) the opener means is not able to move with respect to the test capsule, whereby the opener means opens the operable openable portion when the test capsule is being secured to the lid, and whereby the opener means remains unmoved with respect to the test capsule both before and otter after the operable openable portion has been opened by the opener means;
and
(xi) the opener means is a hollow cylinder having a longitudinal axis which extends along, a longitudinal axis of the apparatus;
and
(xii) the opener means wherein the cylinder has a diameter such that, when the test capsule is secured to the lid, walls defining the cylinder are adjacent generally parallel to one or more walls defining the container, whereby and the opener means opens is configured to open the openable portion over substantially the entire a diameter of the container and thereby allows maximum that is sufficient to allow free flow of the liquid specimen from the container into the test capsule, and from the test capsule back into the container directly through the interior of the cylinder.
