Patent

CA 2286561

The invention concerns a device for diffusing one or several fluid product doses, each dose being contained in a sealed reserve (163) defined by an envelope made of a flexible and ductile material, such that a collapsing pressure (P) applied on the reserve causes the envelope to burst open releasing the product contained in the reserve. The invention is characterised in that the envelope is locally provided with at least a weakened zone forming a pre-opening (165'), so as to cause the envelope to burst open at the pre-opening, thereby channelling the product (F) through the pre-opening in a predetermined direction.

Dispositif pour diffuser une ou plusieurs doses de produit fluide, chaque dose étant contenue dans une réserve étanche (163) qui est définie par une enveloppe en matière souple déformable, de façon qu'une pression d'écrasement (P) exercée sur la réserve provoque l'éclatement de l'enveloppe pour libérer le produit contenu dans la réserve, caractérisé en ce que l'enveloppe est pourvue localement d'au moins une zone d'affaiblissement formant une pré-ouverture (165'), de façon à provoquer l'éclatement instantané de l'enveloppe au niveau de la préouverture, le flux de produit (F) étant ainsi canalisé par la préouverture dans une orientation prédéterminée.
