Abstract
Abstract An appliance for making an aerated beverage comprising a casing (10), a connection (17) carried by said casing for mounting a container (18) of pressurized liquid carbon dioxide, a pivotally mounted shatterproof housing (24) for a bottle of water (29), a nozzle (31) communicating with the connection and extending downwardly within the housing and through a stopper (27) for engaging the neck of the bottle supported within the housing and a safety pressure valve (34) connected to the interior of the bottle when the stopper is engaged in its neck, the housing being axially reciprocable to engage and disengage a latch (47, 48, 49) for the pivotal housing and to unseat the valve (34) at each axial reciprocation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
An appliance for making an aerated beverage, said appliance comprising a casing, a connection carried by said casing for mounting a container of pressurized liquid carbon dioxide, a shatterproof housing for a bottle of water, a nozzle within said housing, a stopper for engaging in the neck of a bottle, means for supporting the bottle in said housing so that the stopper is engaged therein, a safety pressure valve connected to the interior of the bottle when the stopper is engaged in its neck, and a pivotal mounting for the shatterproof housing on the casing mounting the housing for pivotal movement between a first position in which the bottle can be introduced into or removed from the housing and a second position in which the means for supporting the bottle engage the bottle to prevent its removal, said shatterproof housing also being axially reciprocable relative to the casing in addition to its pivotal movement.
Claim 2
Dependent Claim
154 words
An appliance for making an aerated beverage, said appliance comprising a casing, a connection carried by said casing for mounting a container of pressurized liquid carbon dioxide, a shatterproof housing for a bottle of water, a nozzle within said housing, a stopper for engaging in the neck of a bottle, means for supporting the bottle in said housing so that the stopper is engaged therein, a safety pressure valve connected to the interior of the bottle when the stopper is engaged in its neck, and a pivotal mounting for the shatterproof housing on the casing mounting the housing for pivotal movement between a first position in which the bottle can be introduced into or removed from the housing and a second position in which the means for supporting the bottle engage the bottle to prevent its removal, said shatterproof housing also being axially reciprocable relative to the casing in addition to its pivotal movement.
Claim 3
Dependent Claim
37 words
An appliance as claimed in claim 1, and further comprising a releasable latch to lock the pivotal assembly in said second position, the axial movement of said shatterproof housing allowing the engagement and disengagement of said latch.
Claim 4
Dependent Claim
40 words
An appliance as claimed in claim 2, wherein said latch includes at least one rearwardly extending latch member on said shatterproof housing, with latch means thereon, and an element on the casing engagable by said at least one latch member.
Claim 5
Dependent Claim
202 words
An appliance for making an aerated beverage, said appliance comprising a casing, a connection carried by said casing for mounting a container of pressurized liquid carbon dioxide, a shatterproof housing for a bottle of water, a nozzle within said housing, a stopper for engaging in the neck of a bottle, means for supporting the bottle in said housing so that the stopper is engaged therein, a safety pressure valve connected to the interior of the bottle when the stopper is engaged in its neck, and a pivotal mounting for the shatterproof housing on the casing mounting the housing for pivotal movement between a first position in which the bottle can be introduced into or removed from the housing and a second position in which the means for supporting the bottle engage the bottle to prevent its removal, said shatterproof housing also being axially reciprocable, and further comprising a support member for supporting the connection, the shatterproof housing, the nozzle and the stopper and a pivotal connection between the casing and the support member, whereby the shatterproof housing, the nozzle, the stopper and the container of pressurized carbon dioxide all pivot with the support member, relative to the casing, as a pivotal assembly.
Claim 6
Dependent Claim
202 words
An appliance for making an aerated beverage, said appliance comprising a casing, a connection carried by said casing for mounting a container of pressurized liquid carbon dioxide, a shatterproof housing for a bottle of water, a nozzle within said housing, a stopper for engaging in the neck of a bottle, means for supporting the bottle in said housing so that the stopper is engaged therein, a safety pressure valve connected to the interior of the bottle when the stopper is engaged in its neck, and a pivotal mounting for the shatterproof housing on the casing mounting the housing for pivotal movement between a first position in which the bottle can be introduced into or removed from the housing and a second position in which the means for supporting the bottle engage the bottle to prevent its removal, said shatterproof housing also being axially reciprocable, and further comprising a support member for supporting the connection, the shatterproof housing, the nozzle and the stopper and a pivotal connection between the casing and the support member, whereby the shatterproof housing, the nozzle, the stopper and the container of pressurized carbon dioxide all pivot with the support member, relative to the casing, as a pivotal assembly.
Claim 7
Dependent Claim
24 words
An appliance as claimed in claim 4, and further comprising at least one compression spring mounted between said support member and said shatterproof housing.
Claim 8
Dependent Claim
35 words
An appliance according to claim 5, wherein said shatterproof housing includes a cap thereon, extending above said support member, and wherein said at least one spring is engaged between the support member and the cap.
Claim 9
Dependent Claim
34 words
An appliance according to claim 6, and further comprising an element on the shatterproof housing which engages with the safety valve so that, upon axial movement of the housing, the safety valve is open.
