Abstract
Abstract A container for separate storage includes a receptacle for a liquid product, a retaining sleeve having a detachable capsule integrally molded therewith to be separated by tearing of a rupturable wall portion joining the capsule and sleeve for releasing an additional product in the capsule into the liquid product as the capsule falls into the receptacle, and a stopper including a dispensing spout. The stopper is fixed to the retaining sleeve for conjoint rotation around the receptacle neck, and the capsule and the receptacle neck have interengageable reliefs to hold the capsule against rotation whereby twisting the stopper will rotate the sleeve to tear the rupturable wall portion, releasing the capsule. Mixing of the two products may be assisted by the user shaking the container, and the ensuing mixture may be dispensed through the stopper spout.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
205 words
A container for storing and dispensing a liquid product and an additional product isolated from one another during storage, and for dispensing a mixture of the said products, such container comprising a receptacle having a body and a neck, the body of the receptacle constituting a first compartment in which one of the products is placed; a capsule positioned in said neck, said capsule being in the form of a cup having a lateral wall disposed at least partially in said neck; a stopper covering said capsule and co-operating during storage with said capsule to define a second compartment in which said additional product is placed; external relief means on said cup lateral wall within said neck; internal relief means on said neck positioned to engage against said external relief means to hold said capsule against rotation with respect to said neck; retaining sleeve means adapted to engage said neck and to receive the said stopper externally thereon; means defining a rupturable peripheral wall zone joining said retaining sleeve means to said capsule whereby said capsule is carried by the retaining sleeve means; and means connecting said retaining sleeve means and said stopper for preventing rotation of the stopper relative to said retaining sleeve means.
Claim 2
Dependent Claim
205 words
A container for storing and dispensing a liquid product and an additional product isolated from one another during storage, and for dispensing a mixture of the said products, such container comprising a receptacle having a body and a neck, the body of the receptacle constituting a first compartment in which one of the products is placed; a capsule positioned in said neck, said capsule being in the form of a cup having a lateral wall disposed at least partially in said neck; a stopper covering said capsule and co-operating during storage with said capsule to define a second compartment in which said additional product is placed; external relief means on said cup lateral wall within said neck; internal relief means on said neck positioned to engage against said external relief means to hold said capsule against rotation with respect to said neck; retaining sleeve means adapted to engage said neck and to receive the said stopper externally thereon; means defining a rupturable peripheral wall zone joining said retaining sleeve means to said capsule whereby said capsule is carried by the retaining sleeve means; and means connecting said retaining sleeve means and said stopper for preventing rotation of the stopper relative to said retaining sleeve means.
Claim 3
Dependent Claim
66 words
A container as claimed in claim 1, wherein said retaining sleeve means comprises an external skirt, and an internal skirt disposed concentrically with respect thereto; wherein said two skirts being disposed to receive said receptacle neck therebetween in the assembled configuration of the container; and wherein said rupturable peripheral wall zone joins said capsule lateral wall with the said internal skirt of the retaining sleeve means.
Claim 4
Dependent Claim
65 words
A container as claimed in claim 2, wherein said retaining sleeve means further includes an annular sealing rib, interposed between said internal and external skirts; and wherein said external skirt and said sealing rib define together a channel constituting catch means for receiving the rim of said neck therein with a snap fit to fix the retaining sleeve means on said neck of the receptacle.
Claim 5
Dependent Claim
35 words
A container as claimed in claim 1, wherein said capsule lateral wall is substantially cylindrical and said external relief means thereon comprises several teeth extending parallel to the generatrices of the said cylindrical lateral wall.
Claim 6
Dependent Claim
38 words
A container as claimed in claim 4, wherein said neck of the receptacle has a substantially cylindrical internal surface, and said internal relief means thereon comprises several teeth disposed parallel to the generatrices of said cylindrical internal surface.
Claim 7
Dependent Claim
47 words
A container as claimed in claim 5, wherein said teeth on the neck include concave radially inner faces conforming to a first right circular cylinder, and said teeth on the lateral wall of said capsule have convex radially outer faces conforming to a second right circular cylinder.
Claim 8
Dependent Claim
61 words
A container as claimed in claim 6, wherein the diameter of said second right circular cylinder is less than the diameter of the said cylindrical surface of the neck between two adjacent teeth, and the diameter of the said first right circular cylinder is greater than the diameter of said cylindrical lateral wall of the capsule between two adjacent teeth thereof.
Claim 9
Dependent Claim
68 words
A container as claimed in claim 3, wherein said retaining sleeve means includes an inner wall surface; wherein said stopper comprises: an external skirt of generally cylindrical form disposed coaxially with said neck of the receptacle, and an annular sealing rib positioned to bear against one end of the said inner wall surface of the retaining sleeve means; and wherein said stopper skirt surrounds said stopper sealing rib.
Claim 10
Dependent Claim
82 words
A container as claimed in claim 8, wherein said external skirt and said sealing rib of the stopper define together an annular recess; wherein a catch bead is formed in said annular recess; wherein said retaining sleeve means includes means defining an annular groove on one end thereof; and wherein said stopper is adapted to be fixed to the retaining sleeve means by ratchet action engagement of said catch bead in said annular groove on said one of the retaining sleeve means.
Claim 11
Dependent Claim
132 words
A container as claimed in claim 8, wherein said generally cylindrical external skirt of the stopper comprises internally thereof means defining alternate ribs and channels disposed side-by-side therearound and parallel to the generatrices of its internal cylindrical surface, and said external skirt of the retaining sleeve means has a part of its cylindrical surface situated in register with said channels of the skirt, and includes on said part of the cylindrical surface striations disposed side-by-side and parallel to the generatrices of said cylindrical surface, and wherein said ribs of the skirt engage with the striations of the retaining sleeve means, whereby said ribs, and channels of the skirt and said striations of the retaining sleeve means constitute the means for holding the stopper against rotation with respect to the retaining sleeve means.
