Abstract

A container for dispensing reagent slides into apparatus which uses the slides to carry out quantitative chemical analysis of fluid samples. The container is formed of a plurality of casing parts which, when joined together, for a generally rectangular housing with a chamber for receiving a stack of the slides. The container fits into a complementary shaped nest in the analysis apparatus and has discontinuity means for inhibiting improper orientation of the container in the nest. A notch code on the container cooperates with structure on the nest to inhibit placing into the nest a container carrying reagent slides improper for the analysis test to be conducted.

Claims

1. A container for dispensing reagent slides into apparatus (1) having a nest into which said containers are insertable and (2) adapted to use reagent slides to carry out quantitative chemical analysis of fluid samples;

said container comprising;

a plurality of separate casing parts adapted to be joined together to form a generally rectangular housing having (1) a dispensing station for dispensing slides to the apparatus when the container is properly oriented in the nest and (2) a chamber for receiving a stack of the slides to be dispensed into the apparatus through said dispensing station; and

discontinuity means, on at least one of said casing parts, for inhibiting insertion of said container into the nest in all orientations other than the proper orientation, whereby said dispensing station is aligned for injecting slides into the apparatus.

2. A container as set forth in claim 1 wherein said discontinuity means includes a projection on the container positioned to interfere with surfaces of the nest in orientations other than said proper orientation.

3. A container as set forth in claim 1 wherein the nest includes surfaces defining a pair of slots of different dimensions and said discontinuity means comprises:

a first pair of ribs spaced apart by a distance substantially equal to the dimension of one of the slots; and

a second pair of ribs spaced apart by a distance substantially equal to the dimension of the other of the slots.

4. A container as set forth in claim 3 wherein said ribs of said first and second rib pairs are parallel.

5. A container as set forth in claim 3 wherein:

said container is adapted to be inserted into the nest in a predetermined direction; and

said first and second rib pairs extend along the container in a direction parallel to the direction of insertion of said container into the nest.

6. A container as set forth in claim 1 wherein the nest includes surfaces defining a pair of slots of different dimensions and said discontinuity means comprises:

a first pair of ribs on one of said casing parts and spaced apart by a distance substantially equal to the dimension of one of the slots; and

a second pair of ribs on the other of said casing parts and spaced apart by a distance substantially equal to the dimension of the other of the slots.

7. A container for dispensing reagent slides into apparatus (1) having a slotted nest into which said containers are insertable and (2) adapted to use reagent slides to carry out quantitative chemical analysis of fluid samples;

said container comprising;

a plurality of separate casing parts adapted to be joined together to form a generally rectangular housing having (1) a dispensing station for dispensing slides to the apparatus when the container is properly oriented in the nest and (2) a chamber for receiving a stack of the slides to be dispensed into the apparatus through said dispensing station;

a pair of ribs spaced apart by a distance substantially equal to the dimension of the nest slot for inhibiting insertion of said container into the nest in all orientations other than the proper orientation, whereby said dispensing station is aligned for injecting slides into the apparatus; and

a web, extending between said ribs, and adapted to receive a code discontinuity indicative of particular chemical analysis to be performed by the reagent slides received in said chamber.

8. A container as defined in claim 7 wherein said web has a code discontinuity at one of a plurality of positions indicative of particular chemical analysis to be performed by the reagent slides received in said chamber.

9. A container for dispensing reagent slides into apparatus (1) having a nest into which said containers are insertable and (2) adapted to use reagent slides to carry out quantitative chemical analysis of fluid samples;

said container comprising;

a plurality of separate casing parts adapted to be joined together to form a generally rectangular housing having (1) a dispensing station for dispensing slides to the apparatus when the container is properly oriented in the nest and (2) a chamber for receiving a stack of the slides to be dispensed into the apparatus through said dispensing station;

discontinuity means, on at least one of said casing parts, for inhibiting insertion of said container into the nest in all orientations other than the proper orientation, whereby said dispensing station is aligned for injecting slides into the apparatus; and

means for receiving a code discontinuity indicative of particular chemical analysis to be performed by the reagent slides received in said chamber.

10. A container for dispensing reagent slides into apparatus (1) having a nest into which said containers are insertable and (2) adapted to use reagent slides to carry out quantitative chemical analysis of fluid samples;

said container comprising;

a plurality of separate casing parts adapted to be joined together to form a generally rectangular housing having (1) a dispensing station for dispensing slides to the apparatus when the container is properly oriented in the nest and (2) a chamber for receiving a stack of the slides to be dispensed into the apparatus through said dispensing station; and

means for receiving a code discontinuity indicative of particular chemical analysis to be performed by the reagent slides received in said chamber.
