Handle and actuating device for pressurized dispensers

Claim 1

A combined handle and actuating device for a pressurised dispenser of the kind comprising a container containing a pressurised active ingredient and having a discharge valve assembly manually operable by a depressable actuating member, the valve assembly including an annular channel which opens towards the actuating member, which device comprises a body having a handle to be gripped by the user and coupling means adapted for ready supportive attachment to and detachment from the dispenser, and an actuating means operable by the hand of the user holding the handle to depress or release the actuating member, wherein: the coupling means is made of resiliently deformable plastics material and comprises a part annular nose portion and a part annular tail portion diametrically opposed relative thereto so as to be engageable with respective diametrically opposed regions of said channel, and a cantilever connecting means connecting said nose portion to said body downwardly and forwardly to permit resilient deformation of the nose portion relative to the body, diametrically opposed peripheral recesses arranged in the coupling means between the nose portion and the tail portion in order to define said cantilever connection of the nose portion to said body downwardly and forwardly which renders the nose portion more readily deformable than the tail portion, the device being attachable to the dispenser via said coupling means by first inserting the nose portion fully into a region of said channel followed by relative pivotting of the device about the nose portion accompanied by resilient deformation of the nose portion so as to bring the tail portion into snap-fitting engagement with a substantially diametrically opposed region of the channel.
