Abstract: A massage device includes an inner housing containing a vibrational element for generating vibrations to be transmitted to the inner housing and an outer housing to be disposed around the inner housing and so as to define a closed sealed chamber therebetween. The outer housing is releasably sealingly mounted relative to the inner housing so as to be removable therefrom for receipt of a fluid substance therein. The outer housing can advantageously be detached in a quick and ready manner and which then presents an aperture through which the appropriate fluid can be evacuated from, and subsequently replaced, in a quick, clean and easy fashion.

Abstract: A battery compartment (10) associated with a battery-powered electrical device, the compartment (10) including control elements (12) for varying the electrical power delivered to the device; the control elements include a rotatable member (12), a water-proofing washer member (33) located within the control elements (12) and between the rotatable member and a battery contact member (26, 28) so that the operation of the associated electrical device can be controlled while the washer member serves to achieve the required level of water-proofing.
