Problems solved by technology

The disadvantage of this is that the cut part of the closure wall risks retaining a portion of the dose in the reservoir, so that the accuracy and repeatability of the doses are not guaranteed

Embodiment Construction

[0055] figure 1 An external view showing an embodiment of a dry powder inhaler. The inhaler comprises a central body 10 on which two side parts or wings 11, 12 are slidably mounted which form a casing when the device is closed and which can be separated from each other to open the device , so load the device as described below. The body 10 has a generally round shape in the lower part and is relatively flat in the upper part, as figure 1 shown, but it may have any other suitable shape. The body 10 includes an inhalation and dispensing aperture 15 through which the user will inhale when the device is actuated. The two lateral parts 11, 12 forming the casing can be opened by pivoting about a common axis of rotation, eg figure 1 shown, but any other way of opening the device is also contemplated. In addition, it is possible to have only the only casing parts that are active relative to the body, instead of figure 1 the two shown.

[0056] Advantageously, the body includes ...

Abstract

Inhaler comprising a body, at least one cap piece that is movable between a closed position and an open position, individual chambers formed on a chamber supporting member, movable supporting means that take said chamber supporting member and are displaceable between a non-dispensing position and a dispensing position, a device for indicating doses dispensed or yet to be dispensed, said indicating device comprising a rotary indicating piece having indicating means such as numbers, colours and / or symbols, and an actuator operating in conjunction with said movable supporting means to turn said rotary indicating piece, when said movable supporting means return from the dispensing position to the non-dispensing position.

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. Different types of dry powder inhalers exist. The first type of inhaler includes a reservoir for receiving multiple doses of powder, the inhaler being provided with a metering member capable of separating a dose of powder from the reservoir on each actuation in order to bring it into the In the discharge pipeline, it is distributed to the user. Another type of inhaler consists in packaging the powder in pre-determined dose self-contained reservoirs and then opening one of the reservoirs each time the inhaler is actuated. This method of implementation ensures a good seal of the powder, since each dose of powder is only opened when it is expelled. To form these self-contained reservoirs, various variants have been proposed, such as elongated strips of vesicles, or ves...
