` This invention relates to a novel wrapper for a cigar or similar article.

An object of the invention is the packaging of a cigar in a wrapper, preferably of transparent 5 material, which wrapper is provided with notches or tapessuch that a substantial part of the' wrapper can be torn ofi and thrown away leaving on one end of the cigar a portion adapted to act as a mouth-piece. Other objects of this invention will appear from the following detailed descripi rials may be placed in the lm or foil in a defltion and drawing.

In the drawing, wherein like reference numerals refer to the same or similar elements in the respective views:

i; Fig. 1 is a planview of the cigar Wrapped in accordance with this invention,

Fig. 2 is a plan view of a cigar ther wrapper of which has been torn from the cigar except for a short. portion which is adapted to act as a mouth-piece.

Fig. 3 is a, plan View of a wrapped cigar showing a modified form of tear assisting means, and Fig. 4 is a cross-sectional View taken on line 4-4 of Fig. 3. g5 'Many cigar users desire not to have the tobacco of the cigar touch their lips or teeth as `the to- .bacco leaf is irritating to their lips, and for this reason they employ cigar-holders. 'I'hese Q cigar-holders after use become coated with a 3o tarry substance and tobacco particles; and often develop an obnoxious odor, which odor is imparted to the clothes of the user when the holder is carried in a pocket. I have found that the wrapper of the cigar may be utilized as a mouthg; piece to prevent the cigar from touching the users lips.

In accordance with my invention, I Wrap cigars with sheet material, preferably a lm or foil `made of cellulose acetate or other organic derivative or'cellulose, which sheet is provided with means near the end of the cigar forfacllitating the tearing off of the wrapper in such a manner that a portion is left about one end of the cigar. The means for facilitating the tearing of the Wrapper may be either al notch or it may be a tape attached to the wrapperand which may be pulled around the cigar thus tearing the wrapper. The cigar may be wrapped with any suitable sheet material such as thin sheets, foils or papers 4 50 of any suitable composition such as paper, tin foil, Cellophane, etc. It is preferred, however, to use iilms or foils of cellulosev acetate or other organic derivatives of cellulose suchi as the other cellulose esters and the cellulose ethers. Exami ples of other cellulose esters are cellulose formate,

cellulose propionate and cellulose butyrate, while examples of the cellulose ethers are ethyl cellulose, methyl cellulose and benzyl cellulose. The foils may contain, besides the cellulose acetate or other organic d'erivative of cellulose, suitable plasticizers such as triacetin, dimethyl phthalate, diethyl phthalate, dibutyl phthalate, diethyl tartrate, dibutyl tartrate, etc.. and any other desired effect materials such as pigments, iibers, threads and filling materials. The eifect matel0 nite design as a trade-mark or descriptive name to act as an advertisement or to show the origin or genuineness of the contained article.

The thin sheets or foils containing cellulose l5 acetate or other organic derivatives of cellulose are preferably mademoisture proof by coating them with a solution containing cellulose nitrate of either high or low viscosity characteristics with suitable waxes dissolved in at least partial sol- 20 vents for the cellulose acetate or other organic derivative of cellulose. The solution o f cellulose nitrate, if employed, is dissolved vin a suitable solvent or solvent mixture which has no appreciable solvent action on the cellulose acetate contained in the surface of the iilmor foil to be coated and this solution of cellulose nitrate preferably also contains fire retardants -such as tricresyl phosphate or triphenyl phosphate and may also contain water-resistant and water-repellant compounds such as resins and waxes. It is to be understood, however, that any compound or material put into or on the wrapper should be tasteless and odorless.

The wrapper may be placed upon the cigar by wrapping the foil around the cigar or slipping the cigar into envelopes made of the foil and then the loose ends of the foil or the flaps of the envelopes are sealed by application of cement, glue or other adhesive. Any suitable adhesive may be employed, for instance. a solution of cellulose acetate in a volatile solvent. If desired, however, the cigars maybe wrapped with c'ellulose acetate or other thermoplastic foil by rolling the cigarrin the foil and applying heat and pressure at the seam causing the two flaps of the seam to ,be welded together. A suitable method for sealing the wrapper is described in U. S. Patent No. 2,036,873. l

Although this invention is described with par- 5o ticular reference to cigars, the invention is also applicable to other articles adapted to be placed in the mouth such as straws for soda fountains,

individually wrapped cigarettes, etc. A wrapper of cellulose acetate on straws is of particular ading contained on the straws. Although the invention is primarily of importance with reference to cigars, it may also be usedA in connection with candies, confections, ice cream bars and the like where part of the wrapper is torn therefrom leaving a section of the wrapping still intact which may be employed as contact surface for the mouth or lingers.

A description of the wrapper as employed upon cigars will be more fully understood by reference to the drawing. InFig. 1 of the drawing there is shown a cigar I having a cigar band 2 and a Wrapper of cellulose acetate foil 3 wrapped around the same forming a tube surrounding the cigar. The ends of the tube 4 and 5, respectively, are bent over and usually sealed to prevent the cigar from coming out the ends. over-lapping portions 6 of the foil may be cemented together with a suitable adhesive or may be welded together by means of heat and pressure. In the exposed edge I of the tube are formed two notches 8 and 9, the notch 8 being nearer the butt or mouth end of the cigar and 1 the notch 9 being about an inch to an inch and a half from the notch 8.

In the modification shown in Fig. 1, the cigar and tube are grasped between the notches 8 and 9 and the remaining part of the tube torn from the cigar using the notches 8 and 9 as the starting points for tearing.

In the modification shown in Figs. 3 and 4 the cigar is wrapped as described in reference to Fig. .1 except that there is placed about the cigar bands or tapes II and I2, at the points occupied bythe notches 8 and9 in Fig. l. These tapes are attached to the tube at I3 and I4, respectively.

The foil of the tube is cut or scored for a short distance as at I directly over the edges of the tape which acts as the starting point for the tear. In this modication the cigar and wrapper are held in one hand betwen the two tapes I I and I2 and the tapes unwound from the cigar I, the unwinding tearing the covering from the ends 4 and 5 of the cigar leaving a short length of tube I6 which acts as a mouth piece.

The

It is to be understood that the foregoing detailed description is merely given by way of illustration and that many variations may be made therein without departing from the spirit of my invention.

Having described my invention, what I desire to secure by Letters Patent is:

1. The combination with a wrapper of sheet material of a cigar or the like contained in said wrapper, said wrapper being provided with spaced means along an exposed edge thereof to facilitate the tearing of the wrapper to remove portions thereof leaving a portion thereon adapted to act as a mouth-piece.

2. The combination with a Wrapper of ysheet material comprising a derivative of cellulose of a cigar or the like contained in said wrapper, said wrapper being provided with spaced means along an exposed edge thereof to facilitate the tearing of the wrapper to remove portions thereof leaving a portion thereon adapted to act as a mouthpiece.

3. The combination with a wrapper of sheet material comprising cellulose acetate of a cigar or the like contained in said wrapper, said wrapper being provided with spaced means along an exposed edge thereof to facilitate the tearing of the wrapper tc remove portions thereof leaving a portion thereon adapted to act asI a mouthpiece.

4. The combination with a wrapper of sheet material of a cigar or the like contained in said wrapper, said wrapper being provided with spaced notches along an exposed edge thereof to facilitate the tearing of the wrapper to remove portions thereof leaving a portion thereon adapted to act as a mouth-piece.

5. The combination with a wrapper of sheet material of a cigar or the like contained in said wrapper, said wrapper being provided with spaced tapes along an exposed edge thereof to facilitate the tearing of the wrapper to remove portions thereof leaving a portion thereon adapted to act as a mouth-piece.
