Abstract
Abstract A device (10) that includes an ingress aperture (30) which provides improved transport of a drop of liquid, from an exterior surface (16) of the device to the device interior. Means are provided at the intersection of the aperture sidewall (32) and the exterior surface for urging a drop deposited thereon to move into contact with the aperture sidewall and thus into the aperture. In the disclosed embodiments such means are in the form of interior corners (34).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
79 words
A liquid transport device having an exterior surface, an aperture extending from the exterior surface to a zone within the device, said zone having means for transporting the liquid through a zone, characterized in that at least the intersection of said exterior surface and the bounding surface of the aperture includes, at a predetermined location, means for substantially urging a portion of a drop of liquid deposited thereon to move into contact with the bounding surface of the aperture.
Claim 2
Dependent Claim
79 words
A liquid transport device having an exterior surface, an aperture extending from the exterior surface to a zone within the device, said zone having means for transporting the liquid through a zone, characterized in that at least the intersection of said exterior surface and the bounding surface of the aperture includes, at a predetermined location, means for substantially urging a portion of a drop of liquid deposited thereon to move into contact with the bounding surface of the aperture.
Claim 3
Dependent Claim
27 words
A device according to claim 1, characterized in that said urging means comprises a surface configuration capable of forming a compound meniscus on a contacting liquid drop.
Claim 4
Dependent Claim
36 words
A device according to claim 1 or 2, characterized in that said urging means comprises at least one interior corner in the bounding surface of the aperture at at least its intersection with said exterior surface.
Claim 5
Dependent Claim
27 words
A device according to claim 3, characterized in that there are from three to ten similar interior corners at predetermined spaced-apart locations at at least said intersection.
Claim 6
Dependent Claim
15 words
A device according to claim 4, characterized in that there are six of said corners.
Claim 7
Dependent Claim
26 words
A device according to claim 5, characterized in that the bounding surface of the aperture conforms to a regular hexagon at least adjacent the exterior surface.
Claim 8
Independent Claim
35 words
A device according to any one of the preceding claims, characterized in that the transporting means in said zone includes two opposed surfaces of the zone spaced apart a distance such as to cause capillarity.
Claim 9
Dependent Claim
42 words
A device according to claim 7, characterized in that at least one of said two spaced-apart opposed surfaces includes an absorbent layer containing at least one reagent capable of producing a radiometrically detectable signal when contacted by the liquid of the drop.
Claim 10
Dependent Claim
50 words
A device according to claim 3 or any one of claims 4 to 8 when appendant directly or indirectly to claim 3, characterized in that the corner or each of the corners extends throughout the length of the bounding surface of the aperture, from the exterior surface to the zone.
