Title
(EN) TANK OPENING DEVICE FOR FLUID PRODUCT DISPENSING DEVICE
(FR) DISPOSITIF D'OUVERTURE DE RESERVOIR POUR DISPOSITIF DE DISTRIBUTION DE PRODUIT FLUIDE.
Abstract
(EN)
The invention relates to an inhalation device including an opening device for opening an individual tank (20) containing a unique dose of a fluid product, such as a powder, said tank (20) including a closing wall (21), wherein said opening device includes hollow piercing means (40) capable of piercing said closing wall (21) of the tank (20), the hollow piercing means (40) being connected to an ejection channel (69) for conveying the powder towards a dispensing opening (1) of said inhalation device, the opening device including at least one air channel (100) connected to said ejection channel (69) so that, upon an inhalation, an air flow (B) through said at least one air channel (100) is mixed in said ejection channel (69) with the flow of air and powder (A) exiting the tank (20) through said hollow piercing means (40), said at least one air channel (100) being defined by a through hole formed in a wall of said piercing means, and said at least one through hole being substantially parallel to the ejection channel (69).
(FR)
Dispositif d'inhalation comportant un dispositif d'ouverture pour ouvrir un réservoir individuel (20) contenant une dose unique de produit fluide, tel que de la poudre, ledit réservoir (20) comportant une paroi de fermeture (21 ), ledit dispositif d'ouverture comportant des moyens de perçage creux (40) adaptés à percer ladite paroi de fermeture (21 ) du réservoir (20), lesdits moyens de perçage creux (40) étant reliés à un canal d'expulsion (69) pour transporter la poudre en direction d'un orifice de distribution (1 ) dudit dispositif d'inhalation, ledit dispositif d'ouverture comportant au moins un canal d'air (100) relié audit canal d'expulsion (69), de sorte que lors de l'inhalation, un écoulement d'air (B) passant à travers ledit au moins un canal d'air (100) se mélange, dans ledit canal d'expulsion (69), à l'écoulement d'air et de poudre (A) sortant du réservoir (20) à travers lesdits moyens de perçage creux (40), ledit au moins un canal d'air (100) étant formé par un trou traversant réalisé dans une paroi desdits moyens de perçage, ledit au moins un trou traversant étant orienté sensiblement parallèlement audit canal d'expulsion (69).
