Abstract
Abstract A two-compartment container for separate storage of two ingredients of a product for eventual mixing comprises a bottle and a stopper and capsule assembly mounted on the bottle. A tubular capsule is slidably mounted in a tubular sleeve of the stopper to move between upper and lower terminal positions. In the lower terminal position the capsule is sealed, but when the capsule is moved to its upper terminal position, apertures in the sleeve are opened which permit the contents of the capsule to drop into the bottle. The upper end of the capsule is closed by a cap which is provided with a frangible portion which may be broken to provide an aperture through which the contents of the container may be discharged.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
A two-compartment container comprising a bottle having a cylindrical neck, a stopper and capsule assembly mounted on said neck, said stopper and neck having interengaging means to secure said stopper to said neck, said stopper having a tubular sleeve extending downwardly through said neck and terminating in a transverse wall which closes the lower end of said sleeve, the lower portion of said sleeve adjacent said transverse wall having a plurality of apertures extending therethrough, said capsule comprising a tubular wall slidably mounted within said sleeve to move between upper and lower terminal positions, the lower portion of said tubular wall being adapted to close and seal apertures in the lower terminal position of said capsule and to open said apertures in the upper terminal position of said capsule, said tubular wall terminating in a rim which, in the lower terminal position of said capsule, seats against the transverse wall of said sleeve to seal the lower end of said capsule.
Claim 2
Dependent Claim
161 words
A two-compartment container comprising a bottle having a cylindrical neck, a stopper and capsule assembly mounted on said neck, said stopper and neck having interengaging means to secure said stopper to said neck, said stopper having a tubular sleeve extending downwardly through said neck and terminating in a transverse wall which closes the lower end of said sleeve, the lower portion of said sleeve adjacent said transverse wall having a plurality of apertures extending therethrough, said capsule comprising a tubular wall slidably mounted within said sleeve to move between upper and lower terminal positions, the lower portion of said tubular wall being adapted to close and seal apertures in the lower terminal position of said capsule and to open said apertures in the upper terminal position of said capsule, said tubular wall terminating in a rim which, in the lower terminal position of said capsule, seats against the transverse wall of said sleeve to seal the lower end of said capsule.
Claim 3
Dependent Claim
20 words
A two-compartment container as claimed in claim 1, including a closure cap mounted on the upper end of said capsule.
Claim 4
Dependent Claim
38 words
A two-compartment container as claimed in claim 2 in which said closure cap is provided with a frangible portion which when broken provides an aperture in said cap through which the contents of the container may be discharged.
Claim 5
Dependent Claim
