Abstract

The utility model relates to a cigarette filter rod, which is characterized in that: an external layer paper 6 and an internal layer paper 2 with spotty impressed watermark wrap a filtration core rod 1 into the filter rod, which is made to be provided with a concave convex structure, thus increasing the smoke flowing resistance, improving the interception efficiency and filtration effect to the smoke, and reducing to the greatest degree the release amount of the harmful substances and the harm to human bodies. A perfume of a certain degree can be added to the internal layer paper so as to improve the quality of the cigarette. The internal layer paper can improve the hardness of the filter rod, reduce the using amount of wire beams in a filtration core rod on the premise of ensuring the hardness and the interception efficiency and the cost of the raw materials is reduced.

Description

A kind of filter rod

Technical field

The utility model relates to tobacco business, particularly relates to a kind of filter rod of cigarette.

Background technology

At present generally adopt cigarette to prop up to install filter rod additional to alleviate the harm of smoking to human body, but common filter rod just is made up of the outer paper of tow filter core rod and parcel, it is comparatively unobstructed that flue gas passes through the process of filter tip, limited to harmful components filter effects such as tars.For satisfying the requirement of people to health, satisfy people again to the smoking demand simultaneously, must change original filter rod structure, reduce harmful ingredients in flue gas better and reduce tar content to reach.

Summary of the invention

The purpose of this utility model is exactly to increase the resistance of mouth rod to flue gas, improves the efficient of holding back to flue gas, to overcome the deficiency that exists in the prior art.

To achieve these goals, the utility model has adopted following technical proposals: based on common filter rod, it comprises filter core rod and outer paper thereof, it is characterized in that being provided with between outer paper and the filter core rod internal layer paper that one deck has the point-like embossing and wrapping tightly the filter core rod, outer paper is wrapping tightly internal layer paper again, makes and forms corresponding concaveconvex structure on the filter core rod.Internal layer paper is tobacco business fiber filter paper commonly used, thickness has the point-like embossing greater than 0.2 millimeter above it, the embossing shape can be rectangle, circle, triangle etc., the embossing degree of depth should be greater than 0.1 millimeter, and the point-like embossing can carry out rule or irregular overall alignment.Internal layer paper enters opium pipe synchronously with outer paper after being pressed into required point-like embossing by emboss, the filter core rod is rolled into filter rod, because the effect of plasticizer (triacetyl glycerine) is arranged in the filter core rod, the two is cemented, form concaveconvex structure between filter core rod and internal layer paper and the outer paper simultaneously.

Advantage of the present utility model is: because the existence of internal layer paper and point-like embossing thereof is arranged, wrap and compressed tow filter core rod, its density is increased, improved the efficient of holding back to flue gas, by suction, part of smoke air flow direction concaveconvex structure, flow of flue gas resistance and distance have been increased, delayed the holdup time of air-flow at filter rod, having increased horizontal filtration and fiber filter paper filters, thereby improved filter effect, reduced the burst size of harmful substances such as tar to greatest extent and the harm of human body.By adjusting the embossing degree of depth, can change filter core density, can obtain different filter efficiencies, thereby effectively regulate and control coke tar in cigarette.In addition, can also add required spices in the internal layer paper of the present utility model, to improve the quality and the characteristic of cigarette.Because the existence of internal layer paper is arranged, can improve the hardness of mouth rod, guaranteeing hardness and holding back the consumption that can reduce tow in the filter core rod under the prerequisite of efficient, the cost of raw material is also decreased.

The specific embodiment:

For more detailed description the utility model, following routine accompanying drawing provides one group of the best of the present utility model

Embodiment:

Description of drawings:

Fig. 1 is the front view that filter rod of the present utility model removes outer paper;

Fig. 2 is that filter rod and cigarette prop up being connected into the structure cutaway view of cigarette;

Fig. 3 is the local ladder amplification view of the A-A of Fig. 2;

As shown in Figure 1, tow filter core rod 1 is wrapped by embossing internal layer paper 2 and for removing outer paper 3, upper left corner internal layer paper 2 is opened one jiao, and internal layer paper 2 is provided with the point-like embossing 3 of rectangle, is regularly arranged.The embossing of internal layer paper 2 has the interruption blank parts, block (remainder is analogized) from 4,5 of transversals during use, prop up 8 with cigarette and dock and wrap outer paper 6, cigarette is propped up outer paper 9, filter rod internal layer paper 2 parcels, as shown in Figure 2, wherein represented internal layer paper 2 band embossings one end in the filter rod and propped up end with cigarette and dock (wherein label 7 is a tobacco), the structure that its blank parts 10 is outer.Its section structure as shown in Figure 3, its first half is internal layer paper 2 outer parts 10, the latter half is the part of internal layer paper 2 band embossings.

Claims

1, a kind of filter rod, it comprises filter core rod and outer paper thereof, it is characterized in that the internal layer paper that is provided with one deck point-like embossing between outer paper and the filter core rod is wrapping tightly the filter core rod, and filter core rod outer surface forms corresponding convex-concave structure, and outer paper is wrapping tightly internal layer paper again.
