Because of its high absorption and desorption properties, it is necessary to coat the surface with varnish or the like in order to use it as an outer layer. However, if the surface of the outer paper composed of celluloid is coated with varnish or the like, The adhesion of the paper to the cigarette with the filter is reduced, and the outer layer paper is easily peeled off from the tobacco rod or the filter, making it difficult to manufacture the cigarette with the filter.

In addition, since the ink of the celluloid has a low fixing property, when the cellophane is used as the outer layer paper, it is difficult to perform printing on the surface.

Further, the celluloid is different from the paper used in the usual outer paper, and has a plastic touch. Therefore, when using a cigarette with a filter as the outer paper of the celluloid, the smoker's lips or tongue may feel uncomfortable when contacting the outer paper.

An object of the present invention is to provide a cigarette with a filter which reduces or overcomes the problems of the conventional transparent outer paper as described above.

According to the present invention, there is provided a filter-attached cigarette comprising a tobacco rod; a filter disposed at a downstream end of the tobacco rod; and an outer layer of paper wound around a downstream end of the tobacco rod and the filter The outer peripheral surface is connected to the tobacco rod and the filter, wherein at least a part of the outer layer paper is transparent, the transparent portion has a smoothness of 1500 sec or less, and a transparency of 30% or more, and the outer layer paper is made of paper.

According to the present invention, it is possible to provide a filter-attached cigarette having an outer layer paper system which can alleviate or overcome the discomfort of a smoker due to a plastic-like touch or the difficulty in manufacturing, and the like. Point, and has good ink fixing, at least a part of which is transparent.

The outer paper 13 is wound around the downstream end of the tobacco rod 11 and the outer peripheral surface of the filter 12, and the tobacco rod 11 and the filter 12 are connected. The outer layer paper 13 is used for the manufacture of a cigarette with a general filter, and the tobacco rod 11 and the filter 12 are followed by a general adhesive. The type of the adhesive agent for the outer layer paper 13 and the tobacco rod 11 and the filter 12 is not particularly limited, but a vinyl acetate-based adhesive, a starch or a modified starch-based adhesive may be used, or when it is dried. It is essentially an adhesive for transparency. Further, the region to which the adhesive is applied may be a region extending over the entire surface as long as the outer layer paper 13, the tobacco rod 11, and the filter 12 are connected, or may be a portion where the adhesive is not applied. The outer layer paper 13 is transparent as a whole, and has a transparency of 30% or more and 100% or less, preferably 60% or more, 90% or less, more preferably 80% or more and 90% or less. Further, in the present invention, the transparency is measured by whiteness ‧ opacity measuring machine (manufacturer: Murakami Color Technology Research Institute, model: WMS-1), and whiteness and opacity are measured according to ISO 2470 and ISO 2471, respectively. The value calculated from transparency (%) = 100 - opacity (%). The whiteness system uses a specific reflectance meter and a light source to have an intrinsic reflectance coefficient (R∞) when measured at a wavelength of 457 nm and a half-value width of 44 nm. The opacity is determined by a single sheet of visual reflectance coefficient. (R0)/a value calculated from the intrinsic visual reflectance coefficient (R∞) × 100 (%).

(1) Cigarette manufacturing test

In the case of using a general outer paper base paper, a cigarette making machine capable of manufacturing 12,000 cigarettes with a filter per minute is used, and the outer papers of the test samples 1 and 2 and the comparative test samples 1 to 3 are wound around the filter. In the case of cigarettes, the speed at which the cigarette maker can operate (the number of cigarettes that can be made per minute) and the failure rate of the cigarette with the filter, that is, the entanglement of the outer paper, are tested. The results are shown in Table 2. In addition, the failure rate means that when the outer layer paper is wound around the cigarette with the filter, the winding end portion of the outer layer paper is weaker, and the end portion of the outer layer paper is generated from the attached filter with a certain probability. The state in which the cigarette is peeled off. Further, the outer layer paper and the filter and the tobacco rod are followed by a general adhesive used in the manufacture of a general cigarette with a filter, that is, an EVA-based emulsion paste.

Comparing the test samples 1 and 2 to the outer layer of the paper is difficult to wind the tobacco rod and the filter by the cigarette maker. Further, with respect to the comparative test sample 1 in which the surface is not subjected to printing by using a dedicated paste and a dedicated machine, the tobacco rod and the filter can be wound at a low speed condition. However, the comparison test The outer layer of the sample 1 has no coating agent or printing on the surface, because of the high moisture absorption and desorption of the celluloid, and the moisture in the environment is changed after the cigarette is entangled, and the outer paper wrapping portion is stretched or deformed. situation.

On the other hand, the comparative test sample 3 was excellent in the windability of the outer layer paper base paper used in the general outer layer paper. Further, Test Sample 1 and Test Sample 2 were the same as in the case of using the general outer paper base paper (Comparative Test Sample 3), the running speed was 12,000 pieces/min, and the failure rate was 0%, and it was found that there was good winding property.

As shown above, it can be understood that the use of the outer layer of cellophane paper can solve the problem of the entanglement of the transparent outer layer paper of the past.

(2) Ink fixation test

The ink sticking test was carried out on the outer layer paper (25 x 250 mm) of the test sample 2, the comparative test sample 2, and the comparative test sample 3. Further, ink was applied by printing on the surfaces of the outer paper of the test sample 2 and the comparative test sample 3. Further, the surface of the outer paper of Comparative Test Sample 2 was coated with a printing ink and further coated with a varnish thereon. The ink-fixing test system used a vibration-type friction measuring machine (manufacturer: TESTER Industries, trade name: RUBBING TESTER, model: AB-301).

Figure 12 is a diagram for explaining the ink fixing test. The friction measuring machine 9 is provided with a friction washer 91 and a stainless steel disk 92. The friction device 91 is composed of a semi-cylindrical friction body 91a, a cantilever 91b that supports the friction body 91a, and the like. The bottom surface of the friction device 91 is provided with an observation ink White test paper 93 used. Further, an outer layer paper 94 is fixed to the upper surface of the semi-cylindrical stainless steel disk 92.

The ink fixing test was carried on the outer paper 94 by the white test paper 93 in contact with the printed outer paper 94 of the stainless steel disk 92, and rubbed back and forth 40 times by the friction device 91. After the printed outer layer 94, the white test paper 93 was observed to evaluate the degree of color reduction. The friction device 91 is carried on the outer layer paper 94, and the white test paper 93 and the outer layer paper 94 are subjected to the load of the friction body 91a and the cantilever 91b. In addition, the ink fixing test was carried out by a dry test and a wet test, and either of them was carried out at room temperature. Further, in the wet test, 20 μl of water was dropped on the surface of the outer layer 94 before the start of the rubbing.

As a result of the ink fixing test, the outer paper of the comparative test sample 2 was not observed to have a significant ink drop in the dry test, but the ink drop was observed in the wet test. On the other hand, in the test paper 2 and the outer paper of the comparative test sample 3, no significant ink drop was observed in the dry test and the wet test. From this point, it was confirmed that the outer paper using the cellophane has a good ink fixing property as compared with the outer paper of the celluloid, and has the same good ink fixing property as when the general outer paper base paper is used.

(3) Shrinkage test

For the test sample 1, the test sample 2, the comparative test sample 1 and the outer test paper of the comparative test sample 2 were subjected to a shrinkage test. The shrinkage test measures the outer layer of the test object and stores it in an environment of 23 ° C and a relative humidity of 60%. The size at the time of 24 hours is taken as an initial state. Thereafter, it was stored in an environment of 23 ° C and a relative humidity of 100% for 24 hours, and the flow direction and the dimension in the width direction were measured. Further, it was kept in an environment of 23 ° C and a relative humidity of 44% for 1 hour and stored for 24 hours, and the dimensional change in the flow direction and the width direction was measured. The flow direction of the outer layer paper and the dimensional change in the width direction were measured based on the initial state at this time. To assess the shrinkage rate. The results are shown in Table 3. Further, in Table 3, the shrinkage ratio is a result of the above measurement, and the outer layer paper is represented by a positive value when it shrinks more than the initial state, and is represented by a negative value when it is expanded.

It can be clearly seen from Table 3 that the outer paper of test sample 1 and test sample 2 is under the humid condition of 23 ° C and relative humidity of 100%. At the time of storage or storage under a dry condition of 23 ° C and a relative humidity of 44%, the flow direction shrinkage ratio and the width direction shrinkage ratio were both lower than those of the comparative test sample 1 and the comparative test sample 2 outer layer paper. From this, it was confirmed that the use of the cellophane outer layer paper was less affected by the humidity than the use of the cellophane outer layer paper.

Experimental Example 4: Functional test

The functional test system allowed 10 functional inspectors to actually take the cigarette with the filter attached to the outer paper of test sample 2, and the cigarette with the filter attached to the outer paper of test sample 2, to evaluate the outer paper and the functional inspector. The outer layer of paper when the lip or tongue is in contact is implemented as a plastic touch. As a result, the number of people who felt the plastic-like touch in the outer paper was evaluated. Among the cigarettes using the comparative test sample 2 as the filter attached to the outer paper, 9 out of 10 were used, and the test sample was used. Of the 2 cigarettes with a filter, 2 out of 10 people. In addition, the number of people who felt that the outer paper had a plastic-like feel was not found. Among the cigarettes with the filter of Comparative Test Sample 2, 0 out of 10 were used. In contrast, the test sample 2 was used. Among the cigarettes in the mouth, there are 5 out of 10 people.

As shown above, the use of cellophane as the filter-attached cigarette of the outer layer of paper can be confirmed that the outer layer of paper has a reduced touch like plastic compared with the cigarette with the filter of the transparent outer paper (Caifan Fan). .
