The filmormmg materials that may be used are polyvinyl alcohol methylcellulose, carboxy methyl cellulose, polyvinylΧ°αΧ’ ^a5^{d otbers;} and these may be used on any type of filter tip made from synthetic or natural fibers as well as to_ any other filter tip which possesses a flat and Porous end For synthetic fibers, instead of film-forming substance, the coating may consist of a plasticizer which serves to seal the synthetic fibers together to give the desired pattern or design. On filter tips fabricated from materials such as cellulose acetate, the plasticizer may

This invention relates to a novel cigarette filter tip and the method of making the same.

The prime object of the invention centers about the provision of a cigarette filter tip in which an emblem or design in the form of a figure, letter or other insignia is developed in the exposed end of the filter tip as the cigarette is being smoked or consumed.

This object of the invention, more specifically, resides in the production of filter tip cigarettes in which a latent image of an emblem is formed on the exposed end of the t. , --------’ '— may filter, which image, preferably invisible (but whilh may ²⁵ ethyf elvcotiate^ tTit’ ί°^{Γ example}&gt; ^{as methyl pbtb}alyl be partly visible) on. the unlighted cigarette, is developed pShalafeS offier K^Hrorethoxyethyl) by the smoke into distinct or pronounced visibility as the latent u J · ^^{11811 the same effect} the cigarette is lighted and is being consumed fil er ^be_t,^{obtained by} «*ting the area of the

To the accomplishment of this object and such other duced thk ^^{blcb out}.^b“^e °^r border the emblem to beproiX^{Cts aS} ”^{ay bere}&gt;nafter appear, the invention relates ³⁰ the eiosed eXX Xi°.^f “ngs where to the emblematized cigarette filter tip as sought to be defined in the appended claims taken together with the following specification and the accompanying drawings in which:

. Fig.. 1 is a perspective view of a cigarette having a filter tip which embodies the present invention;

. Fig. 2 is a. perspective view of the same shown in a hghted condition and depicting the manner in which the emblem in the exposed end of the filter is developed the cigarette is consumed;

Fig. 3 is a vertical elevational view drawn to an enlarged scale and depicting the filter tip end of the cigarette shown in Fig. 1;

Fig. 4 is a view similar to Fig. 3 and showing a modification thereof;

Fig. 5 is a vertical elevational view of a part of a cigarette machine where the emblems may be applied to the filter tips;

^Fig; 6 is a plan view of the machine parts shown in ,-_nFig. 5 and showing a stencilling apparatus for applying ° , ~ --------XVI ctupiyilix the emblems to the filter tips in accordance with one method of accomplishing the same;

Fig. 7 is a side elevational view of the stencilling annat ratus shown in Fig. 6; ^w^Big· ^{8 is}.^a.^{view shown} to an enlarged scale of a part of the stencilling apparatus; and

V Fig. 9 is a view of said stencilling apparatus taken in » cross-section m the plane of the line 9—9 of Fig 6 Γ . Referring now more in detail to the drawings and having reference first to Fig. 1, the invention is shown embodied in a cigarette 10 having a filter tip 12, the said filter tip comprising a filter body 14 composed of fiber filter material such as natural or synthetic fibers. The filter tip body and particularly the exposed end 16 of the filter body is made to comprise different fiber areas such as 18 and 20, one of which defines a latent image of an emblem or design in the form of a figure, letter or other insignia, the emblem 20 illustrated in Fig. 1 being that of the figure of a heart. The fiber areas 18 and 20 are so constructed or treated as hereinafter set forth that they ,are differently responsive to the emission of smoke when , - *------ _r v/r. lixv uiawuixs wnere the exposed end of the filter tip 12' is shown coated as at zz to produce the latent image 24.

When the cigarette filter tip is produced by this method upon smoking the cigarette, the latent image which may ₃₅ be partly visible but which is preferably invisible is developed into distinct visibility through the condensation f smoke particles on the tip as the cigarette is consumed ^Sa?ί® ^be“^{g developed by the} nicotine and tar coloration of the filter tip uncoated area such as 18 (Figs. 1 to 40 ³&gt;- ,^{In tb}® modification shown in Fig. 4 the emblem is ^dr ^{by the mcot!ne and tar} coloration of that part ot the filter tip area designated as 24.

.^{In 5 t0 9} °^{f the drawings tbere is} shown an appaX X ^be -^{USed for carr}ying out the method of WffhMe ,⁶ X ‘° ^Pr°^{duce the latent} image. With the use of this apparatus the emblem is imprinted ‘^he Wed filter tip ends. Figs. 5 and 6 show cigawhl?! m ^fr°^{m a hopper 28 onto} a rotating wheel 30 which hold and suitably space the cigarettes for ^Pn“ “^{g step}' , ^Tbe individual cigarettes in the movement of the wheel move in contact with a rotary stencil 2, the parts moving m the directions indicated by the arrows m these Figs. 5 and 6, the said stencil being formed with a plurality of stencil openings 34 having the fhe’faid^ste ^β T^{hich is desired to be} imprinted, fi ^d T^{1 be}“^{g shown Wlth} sequential designs of the figures of a heart, diamond, club and spade Wd-^S°T^{ed With the stencil 32 is an} applicator 36 for ihifikP r ^C°T^g “^{aterial t0 the} stencil and thence to shaf? 3R ttt Jhf t^PPl^{1CatOr 3δ} emprises a hollow th ^{ft 38 tbr}?^{ugb wblch the} fiim-forming substance is fed tin iShih¹® ^ΡΓ° K^{ded a}l^{itS terminal witb} an applicator tip 40 which may be made of sponge, felt or any other Porous, substance, the applicator terminal having orifices 65 42 which feed into the applicator tip 40. The applicator tip may be located slightly off-center toward the rim of the. stencil 32, the off-center position introducing a squeezing action to the pliable applicator tip, which latter becomes saturated with the film-forming material and 10 which, m feeding through the stencil openings, imprint and coat the filter tips. ^p

The emblem may also be produced by the method and

2.849,005 apparatus described employing however a heat activatable invisible ink as the imprinting medium. Such a heat activatable ink may be for example one containing the following ingredients by weight: Cobalt chloride -3 parts, ~ water—64 parts, and glycerine—1 part. With this modi- ' flcation the latent emblem would also be invisible pievious to the smoking of the cigarette, but when the cigarette is smoked to a certain length enough heat would be generated in the smoke stream of the cigarette to develop ,θ the pattern of the emblem. . _x .. ’

The emblematized cigarette filter tip of the piesent invention and method of obtaining the same will in the main be fully apparent from the above-detailed description. It will be further apparent that changes may be made in both the product and the method without departing from the spirit of the invention defined in the following claims.
