Transparent groove filter tip cigarette

Abstract

A transparent groove filter-tipped cigarette relates to the technical field of cigarettes and is characterized in that a wrapping layer of a filter tip (2) is provided with a transparent forming paper section (3), a groove filter stick section (4) is wrapped in the transparent forming paper section (3), a plurality of grooves (5) are axially distributed on the peripheral surface of the groove filter stick section (4), and the grooves (5) are opened at the end, close to the cigarette, of the groove filter stick section (4) and stop at the end, close to the lip, of the groove filter stick section (4). A cylindrical groove (6) is formed in the position, at the axis, of the near-lip end of the groove filter stick section (4), the cylindrical groove (6) is open at the near-lip end, and the other end of the cylindrical groove (6) is overlapped with the groove (5) by a certain distance in the axial direction. By means of the reasonable structural design of the filter tip, when a cigarette is smoked, more smoke passes through the grooves in the surface of the lower filter material of the transparent forming paper, more tar can be deposited on the surfaces of the grooves, a smoker can obviously feel existence of the tar through vision, and therefore the concept that smoking is harmful to health is better conveyed.

Description

Technical Field

[0001] The utility model relates to the technical field of cigarettes, in particular to a transparent groove filter cigarette. Background Art

[0002] Everyone knows that smoking is harmful to health. There are also warnings on cigarette packaging that "smoking is harmful to health", but many people still turn a blind eye to this. On the one hand, many people have a low awareness of their own health. On the other hand, when smoking existing cigarettes, most of the tar is filtered by the filter tip and wrapped inside the filter tip, making it impossible for people to see it directly and thus failing to attract more attention. Summary of the invention

[0003] The technical problem to be solved by the utility model is: in view of the above problem, a transparent groove filter cigarette is provided, so that smokers can see the tar produced when smoke flows through the flue, so as to better convey the concept that smoking is harmful to health.

[0004] The technical solution of the utility model is: a transparent groove filter cigarette, comprising a cigarette and a filter, the wrapping layer of the filter is provided with a transparent forming paper segment, a groove filter rod segment is wrapped in the transparent forming paper segment, a plurality of grooves are axially distributed on the outer peripheral surface of the groove filter rod segment, the grooves are opened at the near-smoking end of the groove filter rod segment, and end at the near-lip end, and a distance is left from the end surface of the near-lip end, the near-lip end of the groove filter rod segment is provided with a columnar groove at the axis, the columnar groove is open at the near-lip end, and the other end overlaps with the groove for a distance in the axial direction.

[0005] The technical effect of the utility model is that through the reasonable filter tip structure design, when the cigarette is inhaled, more smoke passes through the grooves on the surface of the filter material under the transparent molding paper, and more tar can be deposited on the groove surface, so that the smoker can clearly feel the existence of tar through vision, thereby better conveying the concept that smoking is harmful to health. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a partial cross-sectional structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0007] like Figure 1As shown, a transparent groove filter cigarette includes a cigarette 1 and a filter 2, wherein the wrapping layer of the filter 2 is provided with a transparent forming paper segment 3, and a groove filter rod segment 4 is wrapped in the transparent forming paper segment 3, and a plurality of grooves 5 are axially distributed on the outer peripheral surface of the groove filter rod segment 4, one end of these grooves 5 opens at the near-smoking end of the groove filter rod segment 4, and the other end of the groove ends at the near-lip end, and a distance is left from the end surface of the near-lip end, and a columnar groove 6 is provided at the near-lip end of the groove filter rod segment 4 at the axis center, and the columnar groove 6 is open at the near-lip end, and the other end overlaps with the groove 5 for a distance in the axial direction. When the smoke flows through the groove filter rod segment, due to the small resistance of the groove on its surface and the shorter distance between the groove and the columnar groove overlapping section, the smoke is more likely to flow along this shortcut. Therefore, more smoke will flow on the surface of the groove filter rod segment and deposit in the groove. It is easier to observe the tar deposition phenomenon through the transparent forming paper segment.

[0008] The distance between the columnar groove 6 and the surface of the groove filter rod segment 4 is smaller than the distance between the columnar groove 6 and the near-smoke end, which helps more smoke flow through the groove.

[0009] At least one solid filter rod segment 7 is provided behind the groove filter rod segment 4, that is, near the lip end. The solid filter rod segment has a smooth end surface and can be blocked outside the columnar groove to improve the appearance. The solid filter rod segment can be an ordinary filter rod segment, or other functional filter rod segments, or a binary or multi-component composite functional filter rod segment.

[0010] The solid filter rod segment 7 is made of cellulose diacetate tow.

[0011] The width of the groove 5 is 0.5 to 2 mm.
