<p>The present invention provides an improved base cup (10) for a pressurised container, such as a plastic aerosol dispenser. The base cup comprises a cup-shaped body (18) for attaching to the base of the pressurised container, the cup-shaped body (18) having a base (22) including a rim (24) enclosing a plurality of support ribs (26). The rim (24) comprises a plurality of deformable zones (30), each zone being disposed on the rim (24) opposite to a respective support rib (26). In this way, the zones are able to deform under the action of an external force, which acts to disperse the force away from the ribs to mitigate against shearing of the base cup away from the container. As a result, the pressurised container is protected from the effects of an impact arising from dropping the pressurised container during transit or use etc. thereby consequently improving safety for the user.</p> |
