Inhaler device
View Patent ↗An inhaler device comprises an inhaler body defining a recess for a capsule holding herein a substance to be inhaled, and a nosepiece communicating with the capsule, and a perforating element coupled to the inhaler body and provided for perforating the capsule for allowing an outside air flow to be mixed with the capsule contents and inhaled through the nosepiece.
1. A suction operated inhaler device, comprising a stationary bottom inhaler body having an air inlet hole, a latching seat and a latching ridge, said stationary bottom inhaler body further defining a recess for holding therein a capsule containing a substance to be inhaled and a top nosepiece communicating with said capsule, said top nosepiece having a bottom flange and being rotatably coupled to said stationary bottom inhaler body to provide, as said top nosepiece is manually rotated by an inhaler device user, at least two operating conditions including an open condition in which said recess for said capsule can be accessed to engage therein a new capsule or to withdraw therefrom a used capsule, and a closed use condition in which said inhaler device nosepiece can be snap locked by snap locking means, said inhaler device further comprising two opposite perforating needles associated with said inhaler body and adapted to perforate said capsule to allow a contents of said capsule to enter said capsule recess thereby an inhaling suction generated air flow passing through said air inlet hole is mixed with said contents of said capsule for inhaling said contents in said recess through said nosepiece, each perforating needle of said two perforating needles transversely sliding against the biassing of a respective coil spring and operating between an abutment element rigid with said inhaler body and a corresponding operating hollow push button having a push button cavity, each said perforating needle being arranged in said push button cavity of each said hollow push-button and having a contour similar to that of a hypodermic needle, including a single beveled tip, each said respective coil spring substantially fully coaxially encompassing a respective said perforating needle with said hollow pushbutton element in a non operated condition thereof.
2. An inhaler device according to claim 1 , wherein said snap locking means comprise a hook portion of said bottom flange or said nosepiece, said bottom flange having a flange ridge engageable with said latching ridge of said inhaler body, said flange comprising a peg having a tooth which can be slidably engaged in a longitudinal slot of a hole formed in said inhaler body, said hole comprising a bottom annular recess in which said tooth can slide, thereby allowing said peg to be rotatively engaged in said hole.
