Abstract

An inhaler is provided for dispensing a pressurized substance, on demand, directly into the mouth of the user. The inhaler in one embodiment operates to dispense the substance when the user exerts a suction on one end thereof, and to terminate the dispensing process when the suction is removed. The inhaler may simulate a cigarette for the self-administration of tobacco or tobacco-like, or other substances, collectively to be referred to herein as nicotine. It is also contemplated that the inhaler may operate in response to other control effects exerted manually or by the mouth of the user, which control effects may be mechanically, thermally, chemically or electrically initiated.

Embodiments similar in appearance and utility to cigarettes, dispensing tobacco or tobacco-like products may be termed "nicarettes" denoting the generically new form of tobacco they represent. No limitation or definition of the scope or spirit of this invention is intended by the presentation of this herein coined word.

Claims

1. A dispenser for introducing a substance into the mouth of a user comprising:

means defining a reservoir for containing the substance in a pressurized state and also defining an inner chamber in axial alignment with the reservoir and having an apertured end portion at the end thereof opposite to said reservoir;

a partition interposed between said reservoir and said inner chamber and having an aperture therein;

an elongated member mounted for reciprocal pivotal movement in said inner chamber and having a first angular position in said inner chamber in which the aperture in the partition is closed, and said elongated member having a second angular position within said inner chamber in which the aperture is open for releasing the substance from the reservoir to the apertured end portion of said inner chamber; and

in which the user selectively introduces suction to the inner chamber through the apertured end portion thereof to move the elongated member from its first angular position to its second angular position so as to cause the aperture in said partition to open to enable the substance in the reservoir to be introduced into the mouth of the user through said apertured end portion under the control of the user.

2. The dispenser defined in claim 1, in which said means defining said reservoir comprises a tubular housing, and in which said means defining said inner chamber comprises a tubular housing coaxial with said first-named tubular housing.

3. The dispenser defined in claim 1, in which said means defining said inner chamber has at least one opening therein to permit air to be introduced into the mouth of the user concomitantly with the pressurized substance.

4. The dispenser defined in claim 1, and which includes spring means engaging said elongated member to bias the elongated member to its first angular position.

5. The dispenser defined in claim 1, and which includes means positioned in the reservoir serving to separate the pressurized substance from a propellant.

6. The dispenser defined in claim 1, and which includes a passage extending through the elongated member from one end thereof to the other, and through which the substance from the reservoir is drawn by the suction of the user when the elongated member is moved to its second angular position.
