Description

A kind of spherical camber filter tip

Technical field

The utility model belongs to cigarette filter preparation technical field, and in particular to a kind of patent application of spherical camber filter tip Matters.

Background technique

In traditional cigarette product, the mostly of cigarette filter use are shape and structure design same with cigarette, i.e., entire filter tip It is uniform cylindrical structure.But cylindrical filter tip is in use, due to the contact defective tightness of human body lip, It is thus easy the excessive air of sucking, and then dilutes flue gas.In addition, lubricity improves with the wetting on filter tip surface, also it is easy to lead Cause cigarette easily to fall off from mouth equal potential problems in suction interval, thus consumption experience sense have it is to be hoisted.

In the prior art, in terms of having focused largely on filter material or filter medium structure to the improvement of filter tip, main purpose is mentioned Harm reduction effect of filter tip is risen, and filter structures itself are improved relatively fewer.Filter structures itself are improved, than more typical Such as: a kind of a kind of " flat beak shape filter tipped cigarette " (application number 2016211070727) and " flat mouth formula cigarette filter rod " (application Number 201621106714) two pieces utility model discloses a kind of novel flat mouth filter tip, by cylindrical cigarette linkage section, flat mouth section and For connect set of transitions that cigarette linkage section is connect with flat mouth section at.The interface of flat mouth section is rectangle, ellipse in two pieces patent Circular rectangle structure can improve the contact surface of filter tip Yu consumer's lip, but this filter structures to a certain extent And the combination of lip is simultaneously non-perfect, and excessively in prolate structure, after prolonged use, however it remains cigarette falls off from oral cavity Potential risk；And a kind of width for the flat mouth section that in addition " flat mouth formula cigarette filter rod " (application number 201621106714) designs Degree is equal with the diameter of cigarette linkage section, then considerably increases the difficulty of processing of filter tip, be unfavorable for the large-scale production of filter tip, because And also result in the limitation of its application.In general, for cigarette filter structure itself, still there is biggish room for improvement.

Summary of the invention

The application is designed to provide a kind of spherical camber filter tip, more harmonious to contact with consumer's lip, Cigarette falling off from oral cavity is preferably prevented simultaneously.

Details are as follows for the technical solution that the application is taken.

A kind of spherical camber filter tip is compounded among two convention filter parts using three-stage composite filter tip structure One spherical arc filters section；When specific preparation, it is preferred to use integral molding techniques are prepared；

The spherical arc filters section, and along filter stick (filter tip) axial longitudal section direction, spherical arc filter section respectively has one above and below The radius of circular arc, the radius of upper circular arc and lower circular arc can be identical or different；The section girth of the spherical arc filter section with Convention filter section perimeter is equal.

In terms of concrete specification, the convention filter partial-length for closing on cigarette is retained in 2.0 ~ 5.0mm, consequently facilitating and cigarette Cigarette；Convention filter part far from cigarette, which can retain or minimize, not to be retained.

Using cigarette prepared by the spherical camber filter tip, it is made of spherical camber filter tip and cigarette.

In general, the spherical camber filter tip with hemispherical curve groove provided herein, can be with consumer's lip Portion's contact is more harmonious, more effectively prevents cigarette from falling off from oral cavity, simultaneously because can compared with the existing production technology of good utilisation, because And there is preferable utilization and extention prospect.

Detailed description of the invention

Fig. 1 is to utilize cigarette side view prepared by spherical camber filter tip provided herein；

Fig. 2 is to utilize cigarette top view prepared by spherical camber filter tip provided herein；

Fig. 3 is in spherical camber filter tip preparation process provided herein along filter stick axial direction longitudal section figure.

Specific embodiment

Explanation is further explained to the application with reference to the accompanying drawing.

Embodiment

As shown in Figure 1, 2, using cigarette prepared by spherical camber filter tip provided herein, by spherical camber filter tip A and cigarette B is constituted.

The spherical camber filter tip (closes on the routine of cigarette in two convention filters using three-stage composite filter tip structure Filter portion 4 and convention filter part 1 far from cigarette) part is intermediate is compounded with a spherical arc filter section 2.

The spherical arc filters section, and along filter stick axial direction longitudal section direction, spherical arc filter section respectively has a circular arc above and below (in the case of vertical view, shape is as shown in mark 3 in Fig. 2)；Under preferable case, the radius (r) of the radius of upper circular arc and lower circular arc It is identical, consequently facilitating production；The section girth of the spherical arc filter section is equal with convention filter section perimeter, consequently facilitating multiple It closes.

Shown in specific top view as shown in Figure 2, the circumference that radius is r is presented in spherical arc, and (respectively having a centre of sphere above and below is circle The center of circle of arc)；

In terms of concrete specification, the convention filter partial-length for closing on cigarette is retained in 2.0 ~ 5.0mm, consequently facilitating and cigarette Cigarette；Convention filter part far from cigarette, which can retain or minimize, not to be retained.

When specifically preparing the spherical camber filter tip, convention filter and spherical arc are preferably filtered into section integrated molding system It is standby, specifically, relative direction is identical using two diameters around filter tip by the prior art after the cylindric filter tip molding of tradition Ball part compacting can (deformation is as shown in Figure 3 in pressing process), the depth (d) and its spherical curve radian of compacting (r) size can adjust suitable dynamics according to actual needs and select the ball part of different-diameter to realize.

Claims (2)

1. a kind of spherical camber filter tip, which is characterized in that three-stage composite filter tip structure is used, it is multiple among two filter portions Conjunction has a spherical arc filter section；

The spherical arc filters section, and along filter tip axial direction longitudal section direction, spherical arc filter section respectively has a circular arc, upper circle above and below The radius of the radius of arc and lower circular arc can be identical or different；The section girth and filter segment perimeter of the spherical arc filter section It is equal.

2. spherical camber filter tip as described in claim 1, which is characterized in that the filter portion length for closing on cigarette is retained in 2.0 ~ 5.0mm。
