Embodiment Construction

[0053] [53] Figures 1 to 8b show a first embodiment of a dry powder inhaler. The inhaler has a central body 10 on which side portions 11, 12 are slidably mounted, forming a lid when the device is closed and adapted to be separated from each other to open the device so that the device administers a drug, such as described later. The body 10 may be generally circular in shape, as shown, but may have any other suitable shape. The body 10 has an oral or suction mouthpiece 15 through which the user inhales when operating the device. The side portions 11, 12 forming the cover are pivotally deployable about a common axis of rotation as shown, but any other means of opening means are contemplated. In addition, only a single movable cover member 11 movable relative to the main body 10 may be provided, as shown in FIGS. 26 and 27 .

[0054] [54] Advantageously, the body has a window 19 through which the count of the doses discharged or to be discharged can be displayed in a manner vi...

Abstract

Opener (40), designed to cut or pierce a single dose holder (21) such as a blister on a strip or disc, has a mechanism (41) that cuts the wall (23) of the product holder so that the cut portion does not obstruct the opening (25) formed in the holder. It comprises two piercing ends (42, 43) separated by a gap, each end being formed by a portion of a hollow cylinder with a cutting edge that allows an air flow to penetrate the holder.

Description

technical field [0001] [01] The present invention relates to a container opening device, and a fluid product dispensing device, particularly a dry powder inhaler, having such an opening device. Background technique [0002] [02] Dry powder inhalers are well known in the art. It exists in various varieties. The first type of inhaler is equipped with a container for receiving multiple doses of powder, said inhaler is equipped with metering parts, each time actuation, a dose of the powder can be dispensed from the container, so that it can be transported to an outlet channel for dispensing to the user. Another type of inhaler consists in dispensing powder doses in predetermined dose containers and then opening one of these containers each time the inhaler is operated. This embodiment ensures a good seal of the powder, since each dose is only opened when it is expelled. To implement these individual containers, various embodiments have been proposed, such as a long strip of ...
