Problems solved by technology

This has the disadvantage that it is difficult to manage the force applied to ensure full opening without risking opening the next reservoir, especially if the opening member should be actuated by suction
This may have the disadvantage that the cut wall section may trap part of the dose inside the reservoir, so that the accuracy and repeatability of the metering is not guaranteed

Embodiment Construction

[0033] The invention preferably relates to a dry powder inhaler. A single embodiment variant is shown in the figures, although many other variants can of course be used. These figures are therefore not limiting. Furthermore, various features of this inhaler can also be implemented to dispense liquids rather than powders. The inhaler comprises a central body 10 on which are slidably or pivotally mounted two side elements or wings (not shown) forming a cover when the device is closed, adapted to separate from each other to open the device and thus Loading device. The body 10 may be substantially circular in shape at the lower portion and relatively flat at the upper portion, as in figure 1 shown in , but the body may have various other suitable shapes. The body 10 includes a dispensing and suction aperture 15 through which the user will inhale when the device is actuated to generate an inhalation flow.

Abstract

The invention relates to a device for dispensing a fluid product that comprises a body (10) provided with a dispensing opening (15), at least one tank containing a metered amount of a fluid product such as a pharmaceutical powder, a mobile bearing means (50) for receiving at least one tank and movable between a non-dispensing position and a dispensing position, a tank opening means (80), a loading means (800), the loading means including an elastically deformable loading member (51), a blocking means (100), an inhalation-triggered means, the device comprising means for modifying the inhalation flow (700) of the user, adapted for using the inhalation flow at the beginning of the inhalation mainly for actuating said inhalation-triggered means, and adapted for using the inhalation flow at the end of the inhalation mainly for expelling the metered amount of fluid product contained in the open tank.

Description

technical field [0001] The present invention relates to fluid product dispensing devices, and in particular to dry powder inhalers. Background technique [0002] Dry powder inhalers are well known in the art. It exists in different types. The first type of inhaler consists of a reservoir that holds many doses of powder, the inhaler is equipped with a metering device that allows a dose of powder to be separated from the reservoir with each actuation to take it to an exit channel for dispensing to the user. Another type of inhaler consists in packing doses of powder in separate reservoirs of predetermined doses, and then opening one of these reservoirs each time the inhaler is actuated. This implementation ensures good powder tightness, since each dose is only opened at the moment of its expulsion. To implement these individual reservoirs, variants have been proposed, such as an elongated strip of blisters or blisters arranged on a circular rotating disk. Inhalers compris...
