Abstract

Abstract Home carbonation apparatus and a carbon dioxide supply vessel (2) are provided with inter-engageable connector parts (10,16). The part on the apparatus includes a hollow cylindrical male member (14) which has an external seal (18) and within which an axially movable valve actuating plunger (30) is positioned. The part on the vessel includes a female member (12) having a cylindrical internal surface (22) for sealing engagement with the seal (10). The bottom surface (26) of the female member (12) acts as a positive stop so that when the parts are connected and locked together the position of the plunger (30) is precisely defined in relation to the position of an axially movable valve actuating rod (6) provided in the vessel (2).

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 154 words
The combination of carbonation apparatus and a carbon dioxide supply vessel detachably mounted therein, the apparatus having a carbonation chamber, a conduit for supplying carbon dioxide to said chamber, a male connector communicating with said conduit for connecting the conduit to the vessel, the male connector including a hollow cylindrical member, and a valve actuator movably positioned inside the male connector; the vessel having a normally closed valve, a female connector for receiving the male connector and having an internal cylindrical surface, and an axially movable valve operating member arranged to be moved by said valve actuator; said combination further including positive stop means limiting axial movement of the male connector into the female connector, seal means providing a gas seal between said male and female connectors, locking means for locking said connectors together, and means for moving said valve actuator for selectively opening and closing said valve when said connectors are locked together.
Claim 2
Dependent Claim 154 words
The combination of carbonation apparatus and a carbon dioxide supply vessel detachably mounted therein, the apparatus having a carbonation chamber, a conduit for supplying carbon dioxide to said chamber, a male connector communicating with said conduit for connecting the conduit to the vessel, the male connector including a hollow cylindrical member, and a valve actuator movably positioned inside the male connector; the vessel having a normally closed valve, a female connector for receiving the male connector and having an internal cylindrical surface, and an axially movable valve operating member arranged to be moved by said valve actuator; said combination further including positive stop means limiting axial movement of the male connector into the female connector, seal means providing a gas seal between said male and female connectors, locking means for locking said connectors together, and means for moving said valve actuator for selectively opening and closing said valve when said connectors are locked together.
Claim 3
Dependent Claim 22 words
Apparatus according to claim 1, wherein said positive stop is provided by end surfaces of each of said male and female members.
Claim 4
Dependent Claim 21 words
Apparatus according to claim 1, wherein said positive stop is provided by a radial projection or rib inside said female connector.
Claim 5
Dependent Claim 27 words
Apparatus according to claim 1 or 2, wherein said locking means comprises a plurality of locking elements movable generally radially for effecting locking between two said parts.
Claim 6
Dependent Claim 29 words
Apparatus according to claim 4, wherein each of said elements has and/or engages an inclined surface effective to draw said connector parts to the fully engaged position during locking.
Claim 7
Dependent Claim 21 words
Apparatus according to any preceding claim, wherein said actuator is a plunger have a retracted position defined by further stop means.
Claim 8
Dependent Claim 77 words
Carbonation apparatus comprising a carbonation chamber, a conduit for supplying carbon dioxide to said chamber; a male connector communicating with said conduit for connecting the conduit to a carbon dioxide supply vessel, said connector including a hollow cylindrical member having a sealing member on its outside; an axially movable plunger positioned inside the male connector for operating a valve operating member of a vessel when connected thereto; and locking means for locking a vessel to said connector.
Claim 9
Dependent Claim 77 words
Carbonation apparatus comprising a carbonation chamber, a conduit for supplying carbon dioxide to said chamber; a male connector communicating with said conduit for connecting the conduit to a carbon dioxide supply vessel, said connector including a hollow cylindrical member having a sealing member on its outside; an axially movable plunger positioned inside the male connector for operating a valve operating member of a vessel when connected thereto; and locking means for locking a vessel to said connector.
Claim 10
Dependent Claim 90 words
A carbon dioxide supply vessel for use with apparatus according to claim 7, having a normally closed valve and a female connector adapted to receive the male connector by axial sliding movement, said female connector having an internal cylindrical surface adapted to be sealingly engaged by said sealing member and a positive stop for limiting axial movement of said male connector into said female connector, said bottle further including an axially movable valve operating member positioned adjacent the bottom of said female connector to be acted on by said plunger.
Claim 11
Dependent Claim 19 words
A vessel according to claim 8, wherein said stop is constituted by an end surface of said female connector.
Claim 12
Dependent Claim 29 words
A vessel according to claim 8 or 9, having, below said female connector, a circumferential rib engageable by said locking means for locking the male and female connectors together.
Claim 13
Dependent Claim 42 words
A vessel according to claim 10, wherein said circumferential rib has an inclined surface engageable by said locking means, the inclination being such as to draw the male and female connectors into their fully engaged position upon operation of the locking means.
