Device for administering orally or nasally a powdered or volatile composition by inhalation
This invention relates to an improved device for administering orally or nasally a powdered or volatile composition by inhalation.
Devices for administering of powdered or volatile compositions are well known. Inhalation of a powdered or volatile composition is through mouth or nostril. The device therefore is required to be adaptable for inhalation by mouth or nostril. The compositions in case of powder are supplied in gelatin containers, which are inserted into the device and opened in some suitable way after which inhalation through the mouthpiece will cause the composition to be released from the container and pass into the human body.
Containers containing such compositions are constructed in two parts and generally of gelatin and are of elongated shape. The compositions in powdered form are filled and two parts of the containers are sealed together at the contacting portions with the help of inter-locking rib and groove arrangements. The inhalation devices for use with such containers normally have a chamber arranged to receive a container containing powdered composition. At least one air inlet aperture leads into the chamber in a generally transversal direction and air from the chamber is inhaled through a nozzle. The air inlet aperture is so arranged that the airflow caused by inhalation through the nozzle will cause the contents of an opened container within the chamber to be released and withdrawn through the nozzle.
Indian Patent Specification No. 154870 provides a device comprising a body shell defining a portion of a chamber, which has a nozzle at a forward end and which is open at the rear end, a sleeve fitted on the outside of the body shell and rotatable with respect to it and having a rear wall closing the open rear end of the chamber, a container retaining means extending through the rear wall of the sleeve into the chamber and having an external entry opening for a container at the rear of the sleeve, an abutment fixed inside the chamber in such a position with respect to the container retaining means that a container retained in the retaining means and projecting from it into the chamber will engage the abutment when the sleeve is rotated with respect to the body shell thereby to separate the projecting portion of the container from the remainder of the container, a guard for preventing the separated portion of the container from passing through the nozzle and an air inlet opening extending through the rear wall of the sleeve into the chamber. A stopper limits the rotation of the sleeve with respect to the body shell.
In the device disclosed in the Indian Patent Specification No. 154870 the container retaining means is provided on the rear wall of the sleeve, and the container positioned in it is faces that the nozzle at the forward end of the chamber. Since the container positioned in the container retaining means is facing the nozzle, the inhalation of composition in the container positioned in the device is in direct line, which may cause entering of the composition excessively, defeating the object of administering compositions by inhalation.
The principal object of the present invention is to have the open end of the container positioned in the device, when opened, facing the rear wall, so that the composition in it can travel into the nozzle taking a "U" turn, and thereby to achieve the maximum effect of the object of administration of composition by inhalation.
According to the present invention an improved device for administering orally or nasally a powdered or volatile composition by inhalation comprising a body shell defining a chamber there within having a nozzle or mouthpiece at a forward end and which is open at the rear end; a sleeve fitted into the inside of the said body shell and rotatable with respect to it and having a rear wall closing the open rear end of the said chamber; a container retaining means in juxtaposition with the said nozzle and extending through the front wall of the said shell body into the said chamber; an abutment fixed inside the said sleeve in such a position with respect to the container retaining means that the container retained in the retaining means and projecting from it into the chamber will engage the abutment when the sleeve is rotated with respect to the body shell separating the projecting portion of the container from the remainder portion; a guard for preventing the separated portion of the container from passing through the nozzle; and an air inlet opening extending through the said front wall of the shell body into the said chamber.

The invention will now be described in detail with reference to the accompanying illustrative drawings, wherein: -
Figure I is sectional elevation of a device according the invention,
Figure 2 is an exploded elevation,
Figure 3 is a sleeve to be fatted into the inside of the body; and 20 Figure 4 is a plan of sleeve shown in Figure 3.
Referring to the illustrations in the accompanying drawings, an improved device for administering orally or nasally the powdered or volatile composition by inhalation comprises of a body shell 10 defining a portion of chamber 12. 14 is a nozzle or mouthpiece at a forward end of the body shell lg.
The chamber 12 in the body shell 10 is open at the rear end. 16 is a sleeve fitted into the inside of the body shell 10. Sleeve 16 is rotatable with respect to the body shell 10 and has a rear wall 18 closing the open rear end of the chamber 12. 20 is a container retaining means in the form of a tube arranged at, and extending, through the front end wall of the body shell 10 which is in juxtaposition with the nozzle or mouthpiece 14, into the chamber 12 and having an external entry opening for a container at the shell body 10. 22 is an abutment fixed inside the sleeve 16 in such a position with respect to the container retaining means 20 that the container 24 retained in the retaining means 20 which projects from it into the shell body 10 will engage the abutment 22 when the sleeve 16 is rotated with respect to the body shell 10 thereby separating the projecting portion 24A of the container 24 from the remainder 248. 26 is a guard for preventing the separated portion 24A of the container 24 from passing through the nozzle or mouthpiece 14. 28 is an air inlet opening extending through the front wall of the body shell 1 0 into the chamber 12.
The abutment 22 may be in the form of a fin or rib and is fixed to the inside of the sleeve 16, and the container retaining means 20 are so disposed with respect to each other that when the body of a container, which is inserted into the tube like container retaining means 20, projects from the retaining means into the chamber 12, the projecting portion of the container will engage a side of the fin or rib when the sleeve 16 is rotated with respect to the body shell thereby to separate the two parts of a container. The projecting portion of the container, which is separated from the remainder portion, remains in the tube like retaining means 20.

28 are air inlet openings, opening into the chamber 12 on the front wall of the shell body 10 and surrounding the tube like retaining means 20. When air is aspirated by a person through the nozzle or mouthpiece 14 the container portion separated from the remainder of the container and disposed in the chamber 12 gets agitated, which serves to empty composition from the separated container body.
 
In the device envisaged according to the present invention, the air through the air inlet openings 28 on the front wall of the shell body 10 carrying composition in the chamber 12 travel in the direction of arrow 30 taking a U turn.
In a preferred embodiment of the invention, the nozzle or mouthpiece 14 and the guard 26 are integral with the body shell 10.
 
We claim:
1. A device for administering orally or nasally a powdered or volatile composition by inhalation comprising; a body shell and a sleeve both defining a chamber with an inlet opening; said body shell comprising a nozzle for inhalation by user, and a container retaining means disposed in substantial closer proximity to said nozzle; and a container separation means in the sleeve to separate a portion of the container to release the material from said container characterized in that upon inhalation by user through said nozzle, the material released from said container is subjected to flow along a substantially u-curve path within said chamber, before reaching said nozzle.
2. The device according to claim 1 wherein the container holder is a cavity adapted for holding a container whereby the body of the container projects inwardly within the chamber.
3. The device according to claim 1 wherein the container separation means is an inwardly projecting rib disposed thereto within the sleeve.
4. The device according to claim 1 wherein the container is made of gelatin.
