Abstract
Abstract A container and cap assembly includes a double barrel dispensing container having two side-by-side outlets, and a cap with two side-by-side closure portions for simultaneously closing both outlets when the cap is connected to the container. The cap includes two protruding orienting sections for orienting the cap relative to the container as the cap is connected to the container. The orienting sections insure that each closure portion comes into contact with the same outlet each time the cap is coupled to the container so that small quantities, if any, of materials flowing through one outlet and deposited on one closure portion of the cap cannot cross-contaminate materials in the remaining barrel after the cap is removed and then re-connected to the container after a dispensing operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A container and cap assembly comprising: a double barrel dispensing container having a neck with peripheral threads for connection with an outlet conduit, said neck having a recess extending transversely through said threads, said neck having first and second side-by-side outlets for simultaneously dispensing different materials; and a cap having first and second closure portions and coupling structrure for releasably connecting said first and said second closure portions to said container in order to substantially close said first and said second outlets respectively, said cap including a protruding orienting section for reception in said recess in order to orient said cap relative to said container as said cap is connected to said container to align said first closure portion with said first outlet and said second closure portion with said second outlet and for substantially preventing said second closure portion from closing said first outlet.
Claim 2
Dependent Claim
145 words
A container and cap assembly comprising: a double barrel dispensing container having a neck with peripheral threads for connection with an outlet conduit, said neck having a recess extending transversely through said threads, said neck having first and second side-by-side outlets for simultaneously dispensing different materials; and a cap having first and second closure portions and coupling structrure for releasably connecting said first and said second closure portions to said container in order to substantially close said first and said second outlets respectively, said cap including a protruding orienting section for reception in said recess in order to orient said cap relative to said container as said cap is connected to said container to align said first closure portion with said first outlet and said second closure portion with said second outlet and for substantially preventing said second closure portion from closing said first outlet.
Claim 3
Dependent Claim
22 words
The assembly of claim 1, wherein said coupling structure includes a pair of flexible arms having hooks for releasably grasping said threads.
Claim 4
Dependent Claim
32 words
The assembly of claim 2, wherein said arms are generally T-shaped and have finger operating segments remote from said hooks, said segments when depressed causing said hooks to release from said threads.
Claim 5
Dependent Claim

Claim 7
Dependent Claim
44 words
The assembly of claim 2, wherein said arms are located generally on opposite sides of said cap; and including at least one generally C-shaped handle connected to said arms for pulling said cap away from said neck while releasing said hooks from said threads.
Claim 8
Dependent Claim
35 words
The assembly of claim 6, wherein said at least one handle is pivotally connected to said arms for swinging movement about an axis generally perpendicular to the direction of extension of said protruding orienting section.
Claim 9
Dependent Claim
19 words
The assembly of claim 1, wherein said orienting section projects outwardly beyond said first and said second closure portions.
