Abstract

PROBLEM TO BE SOLVED: To provide a cigarette packaging product which can prevent the precipitation of crystal caused by the volatile perfume of cigarettes in a package.SOLUTION: A cigarette packaging product has a package, internal package paper stored in the package and comprising adsorption material at least on the inner face side, and cigarettes comprising a volatile perfume stored in the package with the internal package paper.

Description

  The present invention relates to cigarette packaging products.

  Cigarette packaged products have a structure in which a cigarette containing a volatile fragrance (for example, menthol) is housed in a package (for example, a paper package). In storage of such cigarette packaging products, volatile fragrance crystals adhere to the cigarette and impair its appearance. Crystallization of volatile fragrances is mainly caused by a decrease in the environmental temperature where the paper package is placed. That is, when the volatile fragrance contained in the cigarettes is stored in the package at a constant temperature, the volatile fragrance is released and saturated in a vapor state. Saturated volatile perfume steam has a saturated vapor pressure that decreases with a decrease in temperature, and therefore cannot partially exist as steam and generates surplus. The surplus does not precipitate as crystals when absorbed by the inner wall of the package, the paper existing between the package and the cigarette, or the like. However, if the surplus is not absorbed for some reason, it precipitates as crystals. At this time, if crystals are deposited on the cigarette, the appearance of the cigarette is impaired.

  Patent Document 1 discloses a permeable container having an absorbent containing a wetting agent (liquid) for the purpose of controlling the humidity inside a storage container for tobacco products.

  Patent Document 2 discloses a container having a liquid-impermeable layer that includes an absorbent containing a salt solution for maintaining humidity and prevents wetting of a cigarette stored in the container.

  Patent Document 3 discloses a humidity controller that has a liquid impermeable layer that holds a wetting agent in an absorbent layer and prevents wetting of tobacco products stored in a container.

  However, Patent Documents 1 to 3 aim at wetting tobacco products such as cigarettes, and do not contribute to the suppression of crystallization of volatile fragrances contained in cigarettes.

  On the other hand, it is known to arrange an adsorbent on cigarettes themselves, for example, filters. The adsorbent disposed in the filter is intended to reduce the component by adsorbing the component in the mainstream smoke or control the taste, but is effective in suppressing the crystallization of the volatile fragrance. However, if an adsorbent is disposed for the purpose of suppressing crystallization in a filter of a brand product in which the adsorbent is not disposed on the filter, the influence on taste is increased.

The amount of the activated carbon attached was 10 mg per hinge lid type cigarette box 10 (individual package).

  Next, the inner paper piece 30a to which the activated carbon is attached is inserted and returned to the original position of the box body 12 of the hinge lid type cigarette box 10 and is folded again to wrap the cigarette with the inner paper 30, and the lid 14 covers the upper part of the box body 12 Closed. This individual package is sealed with a polyvinylidene chloride (PVDC) film, which is a food wrap film instead of an outer packaging film, so that the box body 12 and the lid 14 are sealed without gaps, and is further placed in a polypropylene (PP) bag with a chuck. Then, air was extracted as much as possible and sealed to prepare a test product.

(Example 2)
A test product similar to that of Example 1 was prepared except that 20 mg of activated carbon was attached to each predetermined body of the inner paper piece taken out in the same procedure as in Example 1.

Example 3
A test product similar to that in Example 1 was prepared, except that 7 mg of activated carbon was attached to a predetermined region of the inner paper piece taken out in the same procedure as in Example 1 per individual package.

Example 4
A test article similar to that of Example 1 was prepared except that 3 mg of activated carbon was attached to each predetermined body of the inner paper piece taken out in the same procedure as in Example 1.

(Comparative Example 1)
A test product similar to that in Example 1 was prepared, except that the activated carbon was not attached to a predetermined region of the inner paper piece taken out in the same procedure as in Example 1.

  The obtained test samples of Examples 1 to 4 and Comparative Example 1 were subjected to an evaluation test for the presence or absence of menthol crystal precipitation as follows.

<Evaluation test>
The obtained test product was stored for 24 hours under normal temperature storage conditions of 22 ° C., waited for the individual package to be filled with menthol vapor, and stored for 12 hours under low temperature storage conditions of 5 ° C. The reason for setting the low temperature storage condition to 5 ° C. is that the crystal was deposited most at 5 ° C. as a result of storage at 10 ° C., 5 ° C., and 0.5 ° C.

The following procedure was used to confirm the presence or absence of crystal precipitation in the test product after storage at low temperature.
(1) The individual package sealed with the PVDC film is taken out from the PP bag of the test product, and the PVDC film is further removed.

  (2) Open the lid of the individual package, unfold the upper folding part so as not to tear the inner paper, and check for crystal precipitation of menthol from the opened inner paper. Do not touch the cigarette directly.

  (3) If menthol crystals are not observed, the inner covering paper on the entire upper surface is removed by cutting along the perforations, and the cigarette is observed in detail to confirm the presence or absence of menthol crystal precipitation. Do not touch the cigarette directly.

  (4) If menthol crystal precipitation is not observed, use a finger to open a gap between cigarettes and check for menthol crystal precipitation.

  (5) If no menthol crystal precipitation is observed, take out all cigarettes and check each one for menthol crystal precipitation. At the same time, it is confirmed whether or not there is crystallization of menthol on the inner surface of the inner paper (the surface in contact with the cigarette).

  These confirmation operations were performed by five panelists and visually observed with naked eyes.

  The presence or absence of crystal precipitation of menthol was defined as “Yes” when a single crystal piece was found, and “No” when no crystal was found.

  The confirmation work was performed in a constant temperature and humidity machine at 5 ° C.

The evaluation test results are shown in Table 1 below. The presence or absence of menthol crystal precipitation is the result of the agreement of all five panelists.

  As is clear from Table 1, it can be seen that the cigarette packaged products of Examples 1 to 4 in which activated carbon is attached to the inner paper have no menthol crystal precipitation and are of high quality.

(Example 5)
The cigarette packaged product shown in FIG. 5 containing a commercially available cigarette (Seven Star Cutting Menthol; Nippon Tobacco Sangyo Co., Ltd. pack containing 150 mg / individual menthol) was prepared and used as a test product.

  In the test product, the outer cover film of the hinge lid type cigarette box 10 was removed, the cover (hinge cover) 14 was opened and opened once, and the folded portion at the upper end of the inner paper 30 in the box body 12 was developed. Thereafter, a film (inserter 40) to which activated carbon was attached was inserted between the cigarette 20 and the front portion 131 of the inner paper 30. The film to which the activated carbon was attached was obtained by cutting a commercially available adhesive tape (cellophane film coated with an adhesive on one side) into 3 cm × 1.5 cm, and depositing a predetermined amount of activated carbon (Kuraray Coal Kuraray Coal GGS28 / 70 on this side). ) Was used. The amount of the activated carbon attached was 10 mg per hinge lid type cigarette box 10 (individual package). The insertion position of the inserter was 1 cm from the front surface and the upper end of the box main body 12 and was partly in contact with the cigarette filter.

  Subsequently, the inner paper 30 was folded again and the cigarette was wrapped with the inner paper 30, and the upper portion of the box body 12 was closed with the lid 14. This individual package is sealed with a polyvinylidene chloride (PVDC) film, which is a food wrap film instead of an outer packaging film, so that the box body 12 and the lid 14 are sealed without gaps, and is further placed in a polypropylene (PP) bag with a chuck. Then, air was extracted as much as possible and sealed to prepare a test product.

(Example 6)
A test article similar to that of Example 5 was prepared except that the amount of activated carbon of the inserter inserted in the same procedure as in Example 5 was 20 mg per individual package.

(Comparative Example 2)
A test product similar to that of Example 5 was produced except that the inserter inserted in the same procedure as in Example 5 was not impregnated with activated carbon.

  The obtained test products of Examples 5 and 6 and Comparative Example 2 were subjected to an evaluation test for the presence or absence of menthol crystal precipitation in the same manner as in Example 1.

The evaluation test results are shown in Table 2 below. The presence or absence of menthol crystal precipitation is the result of the agreement of all five panelists.

  As is apparent from Table 2, it can be seen that the cigarette packaged products of Examples 5 and 6 in which activated carbon is impregnated in the inserter have no menthol crystal precipitation and are of high quality.
