| 摘要 |
<p>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.</p> |
