Abstract

A simulated cigarette contains volatile chemicals for use as an aid in giving up smoking. The chemical may be menthol, peppermint or eucalyptus oils.

Description

SPECIFICATION Simulated cigarettes containing volatile substituents This invention relates to an improved inhaler in the simulated form of a cigarette to be used as an aid to giving up smoking.

Such inhalers are well known and comprise a length of plastictu be the length and diameter of a normal cigarette. This is filled with menthol crystals and a short drilled bush is inserted at each end to retain the menthol crystals and to provide airflow through the inhaler.

Aserious problem associated with this method is that the fine grains of menthol are liable to be drawn through the inhaler leaving an unpleasant taste in the mouth of the user. The use of a sieve to gradethe size ofthe smallestcrystals onlydelaysthe problem F because these will be reduced in size by eveporation until they, too, can be drawn through the mouthpiece. The use of a filter in the mouthpiece also proves abortive the fine grains quickly accumulating on the filter and effectively shut offthe essential airflow.

According to the present invention there is provided a spiral of absorbent material coated with menthol in such away asto eliminatethe use of crystals. Also provided are two filters of absorbent material impregnated with a suitable chemical for improved palatabilityandforcontrolling airflow.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: Referring to the drawing a spiral insert 4 is formed from a suitable length of standard pipe stem cleaner.

This is immersed in a heated mixture of two parts liquified menthol to one part of peppermint oil which, when cooled at room temperature, remains in a semi-solid volatile state. Two filters, 3 and 5, are cut from standard pipe stem filters. In each case one end is cut at an angle of 45 deg. and the other end at90 deg..These are a loose fit in the plastictube 1 and are fitted with the angled endsfacing outwardssothat the extreme tips will rest on the drilled bushes 2 and 6 maintaining a free flow of air. Figure 2 shows an end view offilters 3 and 5 and three indents running the whole length and controlling the passage of air. It is an essential feature ofthis invention that all or any chemicals used must be those medically approved for internal use.

Filter 3 in this example is impregnated with a mixture being 85% peppermint and 15% eucalyptus and filter 5 with pure peppermint oil.

In a further examplefilter3 may be cut at90deg.

each end so that, when in contact with the drilled bush 2, it acts as a non-return air valve preventing undue waste of the volatile ingredients.

In a further example filters 3 and 5 are excluded and the coiled insert4 its extended to the available length between the drilled bushes 2 and 6.

In a further example, the coiled insert 4 is excluded and the filters 3 and 5 are combined in one and extended to the length available between the drilled bushes 2 and 6.. lnthisexamplethefilteris impregnated with a mixture of 50% liquified menthol, 40% peppermint oil and 10% eucalyptus.

1. An inhaler, i n the form of a cigarette, containing volatile chemicals for use as an aid to giving up smoking.

2. An inhaler as claimed in Claim 1 in which an absorbent spirai, impregnated with a mixture of meppermint oil and menthol, is provided.

3. An inhaler as claimed in Claims 1 and 2 in which two filters, impregnated with suitable volatile chemicals, are provided.

4. An inhaler as claimed in Claims2and3in which one end of each filter is cut at an angle to allow free passage of air.

5. An inhaler as claimed in Claims 3 and 4 in which both ends of one filter are cut at an angle of 90 deg. to form a non-return airvalve.

6. An inhaler as claimed in Claim 3 in which the two filters are combined in one.

7. An inhaler for use as an aid to giving up smoking substantially as described herein with reference to the accompanying drawings.

8. The features asherein disclosed, or their equivalents, in any patentably novel selection.

New claims or amendments to claims filed on 15/2/86 Superseded claims 1-8 New or amended claims: 1. An inhalerfor use as an aid in giving upthe smoking oftobacco, which is in the shape of a cigarette and contains within a tube a material coated or impregnated with menthol, and means at the end of each tube for retaining said material whilst allowing the passage of air.

2. An inhaler as claimed in Claim 1, wherein the material is a length of pipe stem cleaner.

3. An inhaler as claimed in Claim 2, wherein the pipe stem cleaner is positioned between two filters which may be impregnated with volatile substances for improving palatability.

4. An inhaler as claimed in Claim 2,whereinthe material is a filter.

5. An inhaler as claimed in any preceding claim, wherein the menthol is mixed with peppermint oil.

6. An inhaler as claimed in Claim3orS,wherein one end of each filter is cut at an oblique angle so as to allow free passage of air.

7. An inhalerfor use as an aid in giving up smoking, substantially as hereinbefore described with reference to the accompanying drawing.
