Technical Field
[0001] This utility model relates to the field of cigarette technology, and more specifically, to a cigarette with an oblique perforation design. Background Technology
[0002] The harmful components of cigarettes mainly come from tar. To improve the tar-reducing effect of cigarette filters, perforations are often made in the filter section to allow for ventilation and tar reduction.
[0003] The existing cigarette filter segments typically have holes that only penetrate the forming paper and tipping paper surrounding the cellulose acetate bundles, making it difficult to meet the increasingly demanding ventilation and tar reduction functions of consumers.
[0004] Therefore, how to provide a cigarette that can effectively improve the ventilation and tar reduction effect of cigarettes has become a technical problem to be solved in this field. Utility Model Content
[0005] One objective of this invention is to provide a new technology solution for cigarettes with an oblique perforation design that can effectively improve the ventilation and tar reduction effect of cigarettes.
[0006] According to a first aspect of the present invention, a cigarette with an oblique perforation design is provided.
[0007] The cigarette with an angled perforation design includes a filter section with a first ventilation hole. The filter section includes a tow core and a wrapping paper wrapped around the tow core. The first ventilation hole extends from the surface of the wrapping paper away from the tow core into the tow core, and the extension direction of the first ventilation hole is toward the tobacco section of the cigarette. The first ventilation hole forms an angle of 30°-60° with the central axis of the tow core.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.
[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0027] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0028] The cigarette with an oblique perforation design provided by this utility model includes a filter section 1 with a first ventilation hole 11. The filter section 1 includes a tow core and a wrapping paper wrapped around the tow core. Typically, the wrapping paper wrapped around the tow core includes forming paper and / or tipping paper.
[0029] The first vent 11 extends from the surface of the packaging paper away from the tow core into the tow core, and the extending direction of the first vent 11 is towards the tobacco segment 2 of the cigarette. The first vent 11 forms an angle of 30°-60° with the central axis of the tow core.
[0030] The first vent 11 extends deep into the filter section 1's fiber core, providing better ventilation and tar reduction compared to traditional cigarettes where the packaging paper only penetrates the filter section. Furthermore, the first vent 11 extends in the opposite direction to the smoke flow, allowing air entering the filter section 1 through it to reduce the smoke velocity and increase tar interception. Additionally, the 30°-60° angle between the first vent 11 and the central axis of the fiber core further enhances the reduction of smoke velocity, resulting in even better tar interception.
[0031] The first ventilation hole 11 of the cigarette provided by this utility model is perforated at an angle. During the smoking process, air enters the fiber core of the filter section 1 through the inclined first ventilation hole 11. The air flow direction is opposite to the smoke direction, which can reduce the smoke flow rate and increase tar retention, thereby achieving a better tar reduction effect.
[0032] In one embodiment of the cigarette with oblique perforation design of this utility model, in order to ensure the tar interception effect while maintaining a good smoking experience, the depth of the first ventilation hole 11 in the tow core is 20%-40% of the radius of the tow core.
[0033] Furthermore, the first vent 11 is 1mm-2mm deep within the filament core.
[0034] In one embodiment of the cigarette with oblique perforation design of this utility model, in order to ensure the tar interception effect while maintaining a good smoking experience, the diameter of the first vent 11 is 0.12mm-0.2mm.
[0035] In one embodiment of the cigarette with an oblique perforation design of this utility model, in order to ensure tar interception while maintaining a good smoking experience, the distance between the end of the first vent 11 and the near-lip end of the cigarette is 12mm-14mm. The end of the first vent 11 refers to the end of the first vent 11 adjacent to the near-lip end of the cigarette.
[0036] In one embodiment of the cigarette with oblique perforation design of this utility model, in order to improve the smoking experience, the first ventilation hole 11 is evenly arranged in a circumferential direction.
[0037] Furthermore, in order to ensure tar interception while maintaining a good suction experience, the number of first vent holes 11 in the single ring is 14-20.
[0038] Furthermore, the filter section 1 is provided with multiple rings of first vent holes 11. Typically, the number of rings of the first vent holes 11 can be 2-3.
[0039] Furthermore, the filter tip section 1 is also provided with a second vent 12. The second vent 12 extends from the surface of the packaging paper away from the filament core into the filament core, and the extending direction of the second vent 12 is towards the filter tip section 1. The second vent 12 forms an angle of 120°-150° with the central axis of the filament core.
[0040] The second vent 12 extends deep into the fiber core of the filter section 1, providing better ventilation and tar reduction compared to traditional cigarettes where the packaging paper is only perforated through the filter section. Furthermore, the extension direction of the second vent 12 is aligned with the direction of smoke flow. Air entering the filter section 1 through the second vent 12 can form a counter-current vortex with air entering the filter section 1 through the first vent 11. The smoke mixes and swirls at this vortex, effectively improving the sensory quality of the cigarette.
[0041] Furthermore, the second vent 12 is arranged in a circumferential manner, and the first vent 11 and the second vent 12 are spaced apart. In a specific implementation, a ring of first vent 11 and a ring of second vent 12 can be provided.
[0042] The following describes a specific embodiment of the cigarette with an oblique perforation design according to this utility model:
[0043] like Figure 1 As shown, the filter section 1 of this embodiment is provided with a ring of first vent holes 11.
[0044] like Figure 2 As shown, the filter section 1 of this embodiment is provided with two rings of first vent holes 11.
[0045] like Figure 3As shown, the filter section 1 of this embodiment is provided with a first vent hole 11 and a second vent hole 12.
[0046] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
