Device comprising a push-button (8), a base element (16) and a cap (10). The push-button (8) is intended to activate a pump (6). The base element (16) is intended to be fixed to the neck (20) of a bottle (4). The cap (10) comprises a sleeve (12) and a membrane (14). The sleeve (12) is made of rigid plastics material, is fixed to the base element (16) and has a tubular portion (22) which extends in an extension direction (30). The membrane (14) is made of elastomer material, is substantially in the form of a disc and extends substantially perpendicularly to the extension direction (30) in the immediate vicinity of the push-button. The membrane has a peripheral edge (28) which is fixed to the sleeve (12) in a sealing manner. The cap defines a cavity (32) which encloses the base element (16) and the push-button (8).
