The present invention relates to an aerosol dispensing device, in which the present invention relates to an aerosol dispensing device in which the following invention relates to an aerosol dispensing device in which: has an open body at one end, inside which the Aero soleplate can be placed, and a lid closing the body.

Aerosols are commonly used, for example, to treat the nose, throat or mouth. Aerosols are delivered nasally or orally to treatment sites by delivery devices, which usually comprise a body to which a removable aerosol container is attached. The body has a dispensing spout, which is usually closed by a removable lid, and an air opening, whereby the medicine is flushed by the air entering the dispensing device and the mixture is discharged from the dispensing spout. These dispensers are designed to be carried in a user’s pocket or handbag. Removable covers often disappear, and foreign substances in the pocket or handbag enter the distribution spout And the air opening, so that the efficiency of handling is affected.

It is an object of the present invention to provide an aerosol dispensing device. Where there are no such disadvantages. The dispensing device according to the invention is characterized in that the body of the device comprises an outwardly extending dispensing spout opening at the end opposite to the open end, that the body has a holder for holding the aerosol container and that the lid is hinged to the body z covers both the open end of the body and the dispensing spout.

A preferred embodiment of the invention is shown in the drawings, in which Figure 1 shows two components of a dispensing device according to the invention, Figure 2 shows the assembled dispensing device open and Figure 3 shows the dispensing device closed.

In the illustrated embodiment of the invention, the dispensing device for nasal aerosols comprises a body 1 and a lid 2 connected to each other by a hinge. The body, lid and hinge are injection molded in two different pieces from a suitable plastic material such as polypropylene. The hinge is preferably a "movable" hinge generally known in the plastics industry, consisting of two thin flexible plates 3, 4 which are made of plastic. Both plates are cast simultaneously with the corresponding component.

The plate 4 includes as part a pin 5 which snaps into a corresponding opening 6 in the plate 3. The cover plate 4 has a part 7, the thickness of which has been reduced. The part 7 has an oblique step Θ to which the oblique edge 9 of the plate 3 is attached when the body and the lid are connected.

The body 1 is substantially cylindrical in shape and is closed at one end 10 and open at the other end 11. To simplify the description, the open end of the body is shown as the upper end. The open upper end 11 leads to a chamber 12 into which the aerosol container (shown in broken lines) for the medicament can be inserted. The chamber terminates in a wall portion 13 with an opening 14 through which the outlet of the aerosol container can be inserted. The chamber further has a rib 15 or some other suitable holder to which a corresponding holder of the aerosol container can be attached, so that the aerosol container remains in place in the chamber but can be removed therefrom if desired. The dimensions of the aerosol container and the chamber are such that there is an air inlet space between the outer wall of the container and the inner wall of the chamber and that the container extends slightly above the upper end of the chamber. Moving the aerosol container towards the end wall of the chamber opens the aerosol valve of the container in the usual way so that the aerosol can move from the opening to the discharge space 16, which is below the end wall of the chamber 3,59337. Air can also come from the chamber air vent into this space.

Out of the discharge space 16, a dispensing spout 17 protrudes from a cylindrical wall of the body. This dispensing spout 17 is inclined upwards.

If the invention is applied to other dispensing devices used, for example, for oral treatment, the dispensing device 17 may have a different shape.

The lid 2 is shaped in such a way that, when in the closed position, it not only closes the open end of the cylindrical body but also encloses the dispensing spout 17 »For this reason, its cross-section is in the shape of an inverted L-letter. The lid thus comprises an upper part connected to the upper end of the body by a hinge plate 4 located on the opposite side of the body to the dispensing spout 17. When the lid 2 is closed, this upper part is located against the upper end of the body (Figure 3). The top includes a low wall or flange that surrounds the protruding end of the aerosol container. When the lid is closed, the top closes the space between the Aero solids tank and the chamber walls against dirt or other contaminants. The lid also has a second part shaped almost as a cylinder segment so that when the lid is closed, it surrounds the dispensing spout, preventing dirt from entering. The lid is closed by pushing it against the body of the dispenser in the position shown in Figure 3.

The dispensing device according to the invention has a pleasant appearance and is easy to open and close, even by children. When the lid is closed, it seals both the air intake space in the body and the dispensing spout against dirt normally found in a pocket or handbag. This is especially important when a delivery device is used to dispense a drug in the treatment of allergic nasal diseases.
