SMOKING PAPER WITH CUSTOM SHAPE AND SMOKING ARTICLE HAVING THE SMOKING PAPER

Abstract

A smoking paper includes a flat sheet or sleeve having a generally rectangular base section and a generally triangular wrapper section defining a dividing line therebetween. The base section has two long sides and two short sides. The wrapper section has a hypotenuse and has a base extending from one of the short sides of the base section to the hypotenuse. The base optionally has a cut-off region enclosing an acute angle with the one short side of the base section. A smoking article includes the smoking paper and a filler disposed on the base section. The sheet or sleeve is rolled into a tube with the base section holding the filler in an interior of the tube and the wrapper section being wound into a spiral at an exterior of the tube. A mandrel and a band may also be provided.

DETAILED DESCRIPTION OF THE INVENTION

[0031] Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1A thereof, there is seen a spread-out sheet or sleeve 1 formed of paper, tobacco leaf or tobacco foil. The sheet or sleeve 1 has a generally rectangular base section 2 and a generally triangular wrapper section 3. The generally rectangular base section 2 has long sides 4, 5 and short sides 6, 7. The long side 4 is indicated as a phantom or dot-dash dividing line which is also a demarcation between the sections 2 and 3. The generally triangular wrapper section 3 has a base 8 and a hypotenuse 9.

[0032] The long sides 4, 5 of the generally rectangular base section 2 have a length of approximately 50-150 mm and the short sides 6, 7 have a length of approximately 15-75 mm.

[0033] The term generally rectangular means that the section 2 is close enough to a purely rectangular shape to permit a filler to be held in place while rolling. The term generally triangular means that the section 3 is close enough to a purely triangular shape to permit the section 3 to be spirally would around the section 2.

[0034] One corner of the generally triangular wrapper section 3 may have a first cut-off region 10, which is approximately vertical and parallel to the phantom line 4. The first cut-off region 10, which may vary in size, is similar to the cut-off region 243 shown in FIGS. 6 and 7 of U.S. Pat. Nos. 9,113,658 and 9,961,935.

[0035] According to the present invention, as shown in FIG. 1B, the base 8 of the generally triangular wrapper section 3 is cut to produce a second cut-off region 12 which is disposed at an angle relative to the first cut-off region 10 and at an angle relative to the short side 7 of the generally triangular wrapper section 3. The second cut-off region 12 extends over all or most of the base 8 of the generally triangular wrapper section 3 and forms an acute angle ? of between 5? and 60? with the short side 7 of the generally rectangular base section 2 shown in FIG. 1C. The second cut-off region 12 makes it easier for the consumer to roll the sheet or sleeve 1.

[0036] It may be seen from FIGS. 1B, 1C and 1D that the angle enclosed by the second cut-off region 12 and the short side 7 and possibly part of the base 8 is variable, with the angle being more extreme from FIG. 1B to 1D to 1C.

[0037] FIG. 2A is a view similar to FIG. 1C. Before the sheet or sleeve 1 is rolled, a filler 13 made of smokable substances, such as smokable herbs, plants, tobacco, homogenized tobacco and/or natural leaf materials is placed on the generally rectangular base section 2. FIGS. 2B and 2C show the sheet or sleeve 1 being progressively rolled around the filler 13 and FIGS. 2D 2G show the fully rolled sheet or sleeve 1 forming a tube 16 in different perspective views.

[0038] After the sheet or sleeve 1 has been rolled into a smoking article, the cut-off region 12 is disposed at a mouthpiece end of the tube 16, and the short side 6 of the generally rectangular base section 2 is disposed at an end of the tube 16 to be lighted.

[0039] FIG. 3A is a view similar to FIG. 1B. FIGS. 3B-3G also show the sheet or sleeve 1 being progressively rolled around the filler. FIG. 3H shows an end-elevational view of the fully rolled sheet or sleeve 1. It is noted that the second cut-off region 12 is not clearly shown in FIGS. 3B-3E merely because of the angle at which the view is shown.

[0040] FIG. 4A is another view similar to FIG. 1B, FIGS. 4B-4D show the sheet or sleeve 1 being progressively rolled, and FIGS. 4E-4K show the fully rolled sheet or sleeve 1 in different perspective views.

[0041] FIG. 5A shows the prior art sheet or sleeve 1 of FIG. 1A, and FIGS. 5B-5F show the fully rolled sheet or sleeve 1 of FIG. 1A in different perspective views. FIGS. 5B-5F also show an optional mandrel 14 around which the sheet or sleeve 1 may be wound. A band 15 may be optionally used to hold the wound sheet or sleeve 1 in place.

[0042] FIG. 6A shows the sheet or sleeve 1 of FIG. 1B and FIGS. 6B-6F show the fully rolled sheet or sleeve 1 of FIG. 1A in different perspective views.

[0043] FIG. 7A shows the sheet or sleeve 1 of FIG. 1C and FIGS. 7B-7F show the fully rolled sheet or sleeve 1 of FIG. 1A in different perspective views.
