Non filter cigarette comprising tobacco rod placed in the cigarette paper and a plastic holder connected to the tobacco rod with tipping paper, characterizes in that, it additionally comprises paper cigarette holder, in all length of which is inserted plastic holder or segments of plastic holder are inserted in outer one-thirds thereof , plastic holder and segments thereof is made as coaxially disposed outer and inner plastic tubes and connecting them several distancing from each other on certain step radial rigidity ribs, with this the relation of the diameter of the opening of inner tube to the outer diameter of outer tube is 0,4.
The invention relates to the cigarette production industry and can be used for manufacturing non filter cigarettes.
It is known non filter cigarette Camel of JT International, which comprises tobacco rod in the cigarette paper.
The disadvantage of the mentioned cigarette is that while smoking the smoker is in uncomfortable condition, in particular, while smoking the cigarette particles of tobacco from a rod get into the mouth of smoker and they should be removed.
It is also known smoking article, comprising tobacco rod in the cigarette paper and cigarette holder made of carton or paper with plasticizer (RU patent Ν°2125822, A24D 1/04). The disadvantage of said smoking article is insufficient firmness of cigarette holder.
The closest to the proposed technical decision is a smoking article comprising tobacco rod in cigarette paper and connected with it cigarette holder by tipping paper, with this the holder is made of food polymer material (RU, ΠΜ j\224616,A241/04).
The disadvantage of the mentioned cigarette is that at the diameter of opening of the plastic holder - 3,80 mm, determined with the chosen relation ^ = 0,48 significant resistance to the tobacco particles into mouth of a smoker cannot be achieved.
The technical task of the proposed invention was to create non filter cigarette, the technical result of which together with securing of the rigidity of the cigarette holder would be minimization of ingress of tobacco particles into mouth of a smoker during smoking and accordingly creation of comfortable condition of smoking.
The mentioned technical result reached by that is that the non filter cigarette comprising tobacco rod placed in the cigarette paper and a plastic holder connected to the tobacco rod with tipping paper additionally comprises paper cigarette holder , in all length of which the plastic tube is placed or plastic segments of the holder are placed in outer one-thirds thereof , the plastic holder and segments thereof are made as coaxially disposed outer and inner plastic tubes connected to each other by several distancing from each other on certain steps radial rigidity ribs, with this the relation of the diameter of opening of inner tube to the outer diameter of outer tube is 0,4.
The constructive accomplishment of plastic holder, segments have got three functions - the function of rigidity of the holder, function of catching tobacco particles and esthetic function. Effect of catching of tobacco particles is enhanced in the second embodiment of the invention, because at insertion plastic segments in outer thirds of the paper holder, they are almost always fixed in turned (shifted) position relatively to each other and consequently the area of passage of axial channels around the inner tube is reduced.
The essence of the invention is explained by the drawings, wherein:
Fig. 1 represents the longitudinal section of the non filter cigarette, in the paper cigarette holder of which is placed the plastic tube;
Fig. 2 - variant of placement of the segments of plastic holder in the outer one- thirds of the paper cigarette holder.
Fig. 3, 4- view from end face of plastic segment and isometric image thereof.
Length of segment is of holder length.
The proposed non filter cigarette (Fig. 1) comprises tobacco rod 1, which is placed into the cigarette paper 2, cigarette holder 3, in all length of which is placed the plastic holder 4 and the tipping paper 5.
In the second version (Fig. 2) of embodiment of the proposed non filter cigarette the segments of plastic holder 4 are placed in the outer one- thirds of the paper cigarette holder 3.
Segment of the plastic holder(Fig.3,4) comprises outer 6 and inner 7 plastic tubes, connected with each other by rigidity ribs 8, forming channels 9 around of inner tube 7.
The advantage of the proposed cigarette in comparison with the existing one is that the convenience of smoking is increased and the esthetic image of cigarette is improved.
