Description

Nov. 30, 1954 A. E. WARNBERG SLIP-ON CIGARETTE TIP Filed April 18, 1951 ATTORNEYS United States Patent O SLIP-N CIGARETTE TIP Archie E. Warnberg, Oklahoma City, Okla. Application April 18, 1951, Serial No. 221,555 1 Claim. (Cl. 13110) This invention relates to a cigarette tip.

An object of this invention is to provide a tip for cigarettes, cigars or the like which is of the disposable type, being formed of paper arranged as a tube which can be easily slipped onto an end of the cigarette.

A further object of this invention is to provide a tubular cigarette tip having a filter element therein which will filter the smoke and will also provide body to the holder to hold the same against collapsing.

A further object of this invention is to provide a tip which may be impregnated with a medicament, flavor or contain a filter which may be impregnated or coated with perfume, flavor, medicament or contain an aromatic element of medical or perfume nature. The tip herein disclosed may be used alone as an inhalent or inhaler of a disposable type.

A further object of the invention is to provide a filter tip of this character having elements disposed therein tending to resist crushing of the tip upon the exertion of excessive pressure by the fingers.

In one form of this invention the tip is formed from a paper or fibrous sheet having secured to one face thereof a corrugated element which may be impregnated with a medicament, flavor, or aromatic element, and a cotton or fibrous filter is disposed forwardly of the corrugated member for filtering the smoke and tar which are drawn from the tobacco in the cigarette.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawings:

Figure l is a plan view of a blank strip showing a series of the filter elements in strip form for separation along a scored or perforated line.

Figure 2 is a longitudinal section through the tip with one of the filter elements in applied position on a cigarette.

Figure 3 is a transverse section taken on the line 3-3 of Figure 2.

Figure 4 is a fragmentary sectional View taken on the line 4-4 of Figure 2.

Referring now to the drawings, inclusive, and, first, to Figure 2 the numeral 18 designates generally a form of slip-on tip which is mounted on the rear end of a conventional cigarette 19. The tip 18 is constructed in the form of a tubular member 20 formed from a strip which is rolled into tubular form with the ends overlapping and adhesively secured together as indicated at 21. The tubular member 20 has disposed therein a corrugated member 22 which terminates at its forward end rearwardly from the forward end of the tubular member 20, and the corrugated member 22 forms channels 23 through which smoke is adapted to be drawn. The corrugated member 22 is preferably formed of absorbent material such as absorbent paper or the like and is preferably impregnated with a medicament, an inhalant, or other aromatic means which is activated by the heat and the smoke passing through the channels 22 and the central channel 24.

At the forward end of the corrugated member 22 a fibrous filter element 25 is positioned, the filter element 25 being in the form of cotton fibers or the like which are rolled into substantially cylindrical form leaving a central opening 26 as shown in Figure 4. The rear or inner end of the cigarette 19 is adapted to abut against the filter member 25 as shown in Figure 8.

The tips hereinbefore described are adapted to be formed in strip form as shown in Figure l with the tips having the tubular member 20 in fiat or strip form and perforations 27 cut through adjacent tips in order that a single tip may be torn from a series of connected tips and then rolled into the configuration shown in Figures 2, 3, and 4. The filter member 25 is adapted to remove any tar, nicotine, or moisture drawn with the smoke from the tobacco in the cigarette 19, and the heat of the smoke passing through the filter 25 will activate the ingredients contained or impregnated in the corrugated member 22. The corrugations within the tube are so dimensioned and arranged that substantially semi-cylindrical, relatively large channels of equal cross sectional area are maintained in each quadrant of the cross-sectional area of the filter with four arcuate webs of substantial length interconnecting the sides of the said channels; the said webs maintaining the relative position of the channels and contributing to the rigidity of the device. This corrugated member 22 will provide body to the rear of the tip so that the tip will not readily collapse when inserted in the mouth. The positioning of the corrugations one in each quadrant of the tip, will assure the presence of channels through the tubular member 20 rearwardly of the filter 25 so that the smoke may be drawn therethrough in the event the rear of the tip should be compressed or substantially collapsed.

What is claimed is:

A slip-on cigarette tip comprising a tubular member of an inside diameter slightly in excess of the outside diameter of a cigarette, a corrugated element formed of a tube of corrugated paper substantially equal in diameter to the outside diameter of the cigarette having a plurality of spaced, straight parallel substantially semi-cylindrical relatively large channels of equal cross sectional area and equally spaced circumferentially within said member, each in a quadrant of the cross sectional area of said member, said tube having a plurality of arcuate webs of substantial length inter-connecting the sides of said channels and being secured to the inner wall of said member to maintain the relative position of said channels and to afford rigidity to the said tip, and said tube terminating at one end inwardly from one end of said member, and a fibrous filter having a central aperture extending longitudinally thereof in said member abutting said corrugated element and terminating short of said one end of said member, whereby said tip may be slipped over the end of a cigarette with said filter in abutting relation with the end of said cigarette, and whereby a substantially equal draft will be obtained in each said quadrant.
