June 9, 1959 I A. VIRMOND PERFUMED-SMOKE PRODUCING BODIEs Filed May 31, 1955 INVENTOR ALEXANDER VIRMOND mwse d M ATTORNEY United States Patent The present invention relates to a smoke-producing body and to a method for making such a body which, when used in conjunction with certain articles, tends to give a natural impression of the smoke normally given off by those articles such, for example, as figures smoking cigarettes. This is a continuation-in-part of my pending application, Serial No. 464,510, filed October 25, 1954, now abandoned.

The known smoke-producing bodies which have been used for this purpose, develop smoke when ignited but fail to give a natural impression of smoke emission since they emit the smoke in a constant stream rather than in intermittent pufis.

Applicant has developed a smoke-producing body which gives intermittent puffs of smoke and thus makes such a body particularly suitable for use in toy or joke. figures which simulate the smoking of tobacco, particularly if the smoke-producing body has the form and appearance of a small cigar or cigarette. Such smoke-producing bodies are also particularly suitable for producing smoke in toys or models in which a particularly natural impression is desired.

It is an object of the present invention to provide a smoke-producing body which will give a deceptively accurate impression of the emission of smoke from an article, for example, such as a figure smoking a cigarette.

In obtaining the object of the invention, one feature resides in providing a smoke-producing body including a combustible core and a particular covering therefor, which, after being ignited, emits smoke intermittently as the covering and core burn at difierent rates.

Another feature resides in incorporating in the smokeproducing body means for excluding any unpleasant smell which normally arises when the core is burned.

Other objects, features and advantages will become more apparent from the disclosure of the application when taken in conjunction with the accompanying drawing wherein:

Fig. l is an end view of an embodiment of the invention;

Fig. 2 is a sectional view taken along lines 2-2 of Fig. 1; and

Fig. 3 is a perspective view of the core of the smokeproducing body being wrapped with a combustible cover.

In many cases, however, it becomes disturbingly obvious that the smell of the combustion products, above all of the core which consists preferably of Celluloid, can give rise to unpleasant inconvenience. Contrary to expectation, however, the attempt to superimpose perfumes on this smell, did not lead to the desired result particularly when perfumes were applied directly to the core which burns away with the unpleasant smell, or were incorporated in the material for the core.

Surprisingly, it has been found that the unpleasant smell can be effectively excluded if at least part of the slow-binning covering of the smoke-producing body contains a perfume. For example, genuine or synthetic scents or perfumes are suitable for this, which produce" the odour of roses, carnations or lavender. Particularly" advantageous is the use of a perfume which produces a smell of pine-needles, since this has proved excellent fordrowning the strong camphor smell of the burning Cellu-j loid.

Naturally other scents such as those which give off-j the genuine smell of tobacco or similar smells may beused.

It was not obvious to include perfumes in the casing because the intermittent smoke-development aimed at in core, an inadmissible shift would occur in the relationship between the burning or smouldering rate of the covering and the combustion rate of the core. Contrary to expectation however, these difdculties have been satisfactorily overcome in spite of the introduction of perfumes into the covering, the functional capacity of the smoke-producing body is retained adequately, particularly if, according to an advantageous embodiment of the present invention, the smoke-producing body is manu-f factured in such a manner that only part of the covering contains the perfume while the rest remains untreated so the smoulderingcan continue in this part undisturbed and at the necessary speed.

Insofar as it is a question of the manufacture of smoke-producing bodies, in which the core 1 is woundround with a paper casing, the procedure is preferably such that the strip of paper 2 forming the covering,

the width of which corresponds to the length of the core; is only partially impregnated with a solution of perfume, preferably by dipping. For example, about a quarter of; the length of the strip may be dipped, then removed from the solution, after which the solution rises further in the' strip. Only when about half the strip has been impreg nated in this manner is further spreading of the perfume solution prevented by rapid drying. The strip which is v half impregnated with the perfume, is then wound round the core in such a manner that the impregnated portion forms the inner layer, i.e. the winding is begun with the impregnated side 3 so that the outer layers of the finished covering do not contain any perfume.

It is also possible, however, to depart from this method of operation and to distribute the perfume differently in the casing, the purpose of improving the smell or distinctly perfuming being likewise achieved practically perfectly. The finished unperfumed or, if necessary, preliminarily perfumed bodies, i.e. cigarettes, may, however be wholly or partially covered in a solution of a perfume or be exposed, for example in a container, to the action of dry odorous substances, i.e. dry perfume.

As indicated, the perfume is preferably introduced in dissolved form, the nature of the solvent used depending naturally on the type of perfume. In general, however, isopropyl alcohol has proved satisfactory.

In order to increase the production of smoke and to improve still further the drawing capacity during combustion, the finished smoke-producer may, to advantage, be provided externally with a thin coating of an oxygenevolving agent, particularly saltpeter, which may be done, for example, by sprinkling with a 5 percent solution.

I claim:
