Abstract
Abstract A connection device for two components, for example a container and a dispenser, provided with a member moveable between two positions. In the first position the member permits engagement of the two components. The member moves between the first and second position upon either connection or disconnection of the components and can not be readily moved back to the first position with the member. In the second position the components can not be re-engaged.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
195 words
A first fluid-handling device having a fluid outlet portion; a second fluid-handling device having a fluid inlet portion, wherein said first fluid-handling device is a container and the second fluid-handling device is a dispenser; means for coupling said fluid outlet portion to said fluid inlet portion including support means extending from one of said fluid handling devices towards the other; a member directly mounted to said fluid outlet portion and movable axially relative thereto between a first position and a second position so that in the first position said movable member and said support means are engaged and said fluid outlet portion is coupled to said fluid inlet portion and in the second position the movable member and the support means can be disengaged so that the said fluid outlet portion and said fluid inlet portion can be disconnected; and means for preventing axial movement of said movable member from said second position to said first position; the support means comprising arms depending from the dispenser having formations adapted to engage with the member in the first position, and adapted to permit disengagement of the container therefrom when the number is in the second position.

Claim 5
Dependent Claim
195 words
A first fluid-handling device having a fluid outlet portion; a second fluid-handling device having a fluid inlet portion, wherein said first fluid-handling device is a container and the second fluid-handling device is a dispenser; means for coupling said fluid outlet portion to said fluid inlet portion including support means extending from one of said fluid handling devices towards the other; a member directly mounted to said fluid outlet portion and movable axially relative thereto between a first position and a second position so that in the first position said movable member and said support means are engaged and said fluid outlet portion is coupled to said fluid inlet portion and in the second position the movable member and the support means can be disengaged so that the said fluid outlet portion and said fluid inlet portion can be disconnected; and means for preventing axial movement of said movable member from said second position to said first position; the fluid outlet portion comprising a neck of substantially circular cross section and the member comprises a collar slideably movable on the neck between the first and second positions which positions are defined by formations on the neck.
Claim 6
Dependent Claim
195 words
A first fluid-handling device having a fluid outlet portion; a second fluid-handling device having a fluid inlet portion, wherein said first fluid-handling device is a container and the second fluid-handling device is a dispenser; means for coupling said fluid outlet portion to said fluid inlet portion including support means extending from one of said fluid handling devices towards the other; a member directly mounted to said fluid outlet portion and movable axially relative thereto between a first position and a second position so that in the first position said movable member and said support means are engaged and said fluid outlet portion is coupled to said fluid inlet portion and in the second position the movable member and the support means can be disengaged so that the said fluid outlet portion and said fluid inlet portion can be disconnected; and means for preventing axial movement of said movable member from said second position to said first position; the fluid outlet portion comprising a neck of substantially circular cross section and the member comprises a collar slideably movable on the neck between the first and second positions which positions are defined by formations on the neck.
