A bracelet to be worn on the wrist which includes a dispenser for dispensing liquid or powdered materials such as sunblocks or germicides. The dispenser on the palm side of the wrist and when the user presses an activator, the dispenser emits a portion of the material onto the user's palm. The dispenser is approximately the size of a wrist watch. A preferred embodiment of the dispenser employs a pump which will work at any orientation. The pump uses air pressure differences produced by the movement of a piston to pull the material into a chamber and expel it from the chamber through a one-way valve. The one- way valve in a preferred embodiment of the pump is made from a silicon diaphragm which opens when it flexes in response to pressure differences and a support for the diaphragm which permits it to flex in only one direction.

La présente invention vise un bracelet à porter sur le poignet qui comporte un distributeur de matières liquides ou en poudre telles que des écrans solaires ou des germicides. Le distributeur se trouve sur le côté paume du poignet et, quand l~utilisateur appuie sur un actionneur, le distributeur diffuse une partie de la matière sur la paume de l~utilisateur. Le distributeur a la taille approximative d~une montre-bracelet. Un mode de réalisation préféré du distributeur ci-décrit emploie une pompe qui peut fonctionner dans n~importe quelle orientation. La pompe utilise les différences de pression d~air produites par le mouvement d~un piston pour attirer la matière dans une chambre et l~expulser de la chambre par une valve unidirectionnelle. La valve unidirectionnelle d~un mode de réalisation préféré de la pompe est constituée d~un diaphragme en silicone qui s~ouvre quand il se plie en réaction aux différences de pression et un support pour le diaphragme qui lui permet de se fléchir dans un sens uniquement.
