Embodiment Construction

[0045] [45] The present invention is particularly applicable to powder or powder product inhalation devices, and a preferred embodiment thereof is described below. However, it is clear that the invention is not limited to such devices, but generally, the invention relates to any device for dispensing powdered products.

[0046] [46] The inhalation device according to the invention has at least one pre-dose container 10 which is hermetically closed and contains a single dose of the powder product. Advantageously, the container 10 comprises a bottom layer 11 forming a chamber for receiving the powder product. The bottom layer may be aluminum. A sealing layer 12 is fixed to said bottom layer 11, for example by gluing, heat welding or any other suitable fixing means. Preferably, the sealing layer is hermetic, airtight and moisture-tight to the powder product and may contain aluminium. A plurality of pre-dose containers may be formed on a common support, for example in the form ...

Abstract

A fluid dispenser device comprising: at least one predosed reservoir ( 10 ) that is hermetically sealed and that contains a single dose of powder; an expulsion channel ( 20 ) that is terminated by a mouthpiece; and a reservoir opening system ( 30 ), each reservoir ( 10 ) including a closure layer ( 12 ) that is suitable for being pierced and / or torn by said opening system ( 30 ) so as to enable the powder that is contained in said reservoir ( 10 ) to be expelled through said expulsion channel ( 20 ), said reservoir opening system ( 30 ) comprising at least two piercer elements ( 31 ) that are actuated so as to create at least two distinct openings ( 25, 26 ) in said closure layer ( 12 ), forming at least one inlet passage ( 25 ) for the flow of gas, in particular air, and at least one outlet passage ( 26 ) for the powder entrained by said flow of gas, and said device including an inhalation trigger system ( 50 ) that creates a flow of gas in said expulsion channel ( 20 ) only when a user inhales at or above a predetermined inhalation threshold.

Description

technical field [0001] [01] The present invention relates to fluid product dispensing devices, and in particular to inhalation devices for powder or powder products. Background technique [0002] [02] Powder product inhalation devices are well known in the prior art. Some of these devices have a common container containing doses of powder product, and dosing means adapted to extract a dose of powder product per actuation for expelling it towards the user. Other devices are provided with individual pre-dosed containers, such as blisters, each containing a single dose of powdered product, each container being separately released when actuated to allow the discharge of its contained product. Open. Within the scope of a device provided with one or more pre-dose containers, various solutions have been proposed for opening the containers and giving access to the contents to expel them. Therefore, it has been proposed to implement pre-dose containers having a peelable layer whic...
