Abstract

A dispensing device, particularly for use in testing cows for mastitis, is adapted to be secured to the open neck of a flexible container having a supply of teat testing or treating liquid therein and consists of a plurality of independent upwardly opening cups connected to centrally located means for securing the cups to the open neck of the container. A conduit having a bore therein extends through the centrally located means and includes a free end located at an elevation above the cups. The conduit has at least one recess formed on its exterior surface and is surrounded by a cap at its free end, thereby to provide a path between the conduit and the cap for liquid in the container forced through the bore of the conduit by squeezing pressure. A plurality of channels extend from the conduit to the cup to receive this liquid and direct it into the respective cups. The flexible container, in addition to holding the reagent, also acts as a handle for the dispensing device attached to it.

Claims

1. An open top dispensing device adapted to be secured to the open neck of the flexible container having a supply of liquid therein, said device comprising a plate having centrally located means integrally formed therewith for securing the plate to the open neck of the container and a plurality of open top cups formed therein about said centrally located means and adapted to contain liquid therein;

a conduit formed integrally with said plate and extending through said centrally located means to a free end located at a position above the plate, said conduit having a bore therein to permit passage of liquid from said container into said cups;

a cap surrounding the free end of the conduit above the plate;

said conduit having a recess portion formed therein on its exterior surface above the plate thereby to provide, between the conduit and cap, a path for liquid in the container forced therefrom by squeezing pressure, said cap serving to direct said liquid from the bore of the conduit along said path towards the plate;

said plate having a plurality of channels formed therein extending from said conduit to said cups to distribute fluids from said path to said cups.

2. The device as defined in Claim 1 wherein said conduit has a plurality of independent recesses formed on its outer surface respectively assOciated with said channels and said cup includes a top section spaced from the free end of the conduit and a continuous side wall surrounding said recesses.

3. The device as defined in Claim 2 wherein said conduit has a plurality of generally radially extending ribs formed thereon defining said recesses therebetween on the portion of the conduit above the plate.

4. A dispenser cup defined in Claim 3 including a flexible tube attached to the portion of the conduit below said plate and within said centrally location means, said tube extending into the liquid in said container.

5. The dispenser cup as defined in Claim 1 wherein said open neck of the container is threaded and said centrally located means comprises an annular skirt extending downwardly from said plate and having internal threads formed thereon for threaded engagement with said open neck.

6. A dispensing device adapted to be secured to the open neck of a flexible container having a supply of liquid therein said device comprising a plurality of independent upwardly opening cups, means centrally located between said cups and connected thereto for securing said cups to the open neck of the container;

a conduit extending through said centrally located means and having a free end located at an elevation above said cups, said conduit having a bore therein to permit passage of liquid from said container into said cups;

a cap surrounding said free end of said conduit;

said conduit having a recess formed therein on its exterior surface, therby to provide a path between the conduit and cap for liquid in the container forced therefrom by squeezing pressure; and

a plurality of channels extending from said conduit to said cups for receiving liquid from said path and directing it to said cups.

7. The device as defined in claim 6 wherein said cups, conduit and centrally located means are integrally formed as a one piece member.

8. The device as defined in claim 7 wherein said plurality of cups comprise four cups arrayed above said centrally located means and conduit in a square pattern.

9. The device as defined in claim 8 wherein said conduit has a plurality of independent recesses formed on its outer surface respectively associated with said channels and said cap includes a top section spaced from the free end of the conduit and a continuous side wall surrounding said recess.

10. The device as defined in claim 8 wherein said conduit has a plurality of generally radially extending ribs formed thereon defining said recesses therebetween on the portion of the conduit above the cups.

11. The devices as defined in claim 10 wherein said channels are integrally formed between said conduit and said cups and said ribs have extensions connecting them to the sides of their associated channels to separate the channels from one another.
