  According to the thin paper packaging body of the present invention, an effect of improving the advertisement appeal effect is produced by adopting the above configuration.

The perspective view which shows the external appearance of the thin paper packaging body which concerns on this invention. X-X 'sectional drawing and the principal part enlarged view in the thin paper package of FIG. The perspective view which shows a state when taking out a thin paper from the thin paper packaging body which concerns on one Embodiment of this invention. (A), (b) is a perspective view which shows the state which folded the thin paper based on this invention. (A), (b) is a perspective view which shows one Embodiment of the thin paper packaging body based on this invention, and X-X 'sectional drawing of another form in the thin paper packaging body of FIG.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the accompanying drawings. Note that the same number is assigned to the same element throughout the description of the embodiment.

  As an example of this embodiment, a pocket tissue that stores tissue paper as a thin paper will be described. FIG. 1 is a perspective view showing an appearance of a thin paper package according to the present invention, and FIG. 2 is an X-X ′ sectional view and an enlarged view of a main part of the thin paper package of FIG. As shown in FIG. 1 and FIG. 2, the thin paper package 1 is composed of a thin paper laminate 10 in which tissue paper as the thin paper 11 is laminated, and a flat packaging material 20 having a substantially rectangular parallelepiped shape having a thin paper outlet 21. ing. The thin paper 11 has a different color tone (see 11a to 11g), and the thin paper laminate 10 is formed by laminating at least three layers of thin paper having different color tones. Further, the packaging material 20 has a thin paper outlet 21 in the longitudinal direction of the substantially central portion of the surface of the thin paper packaging body 1.

  FIG. 3 is a perspective view showing a state when the thin paper is taken out from the thin paper package. As shown in FIG. 3, when using the thin paper packaging body 1, the perforation 21 a formed along the longitudinal direction of the surface of the packaging material 20 is cleaved to form the thin paper outlet 21. A finger is inserted into the packaging material 20 from the outlet 21, and the thin paper 11 at the top is picked and pulled out.

  In the present embodiment, the absolute value of the color difference ΔE in the L * a * b * color system between adjacent thin papers 11 is 10 or more and 150 or less. When the color difference ΔE is less than 10, since the color difference between adjacent thin papers is too small, the difference in color tone cannot be recognized by the consumer, and it becomes difficult to differentiate from conventional colored thin papers. That is, it becomes difficult to obtain the advertisement appeal effect of the thin paper package 1. Conversely, when the absolute value of the color difference ΔE exceeds 150, the manufacturing cost of the thin paper 11 increases.

  Further, the thin paper laminate 10 only needs to have a color difference ΔE in the L * a * b * color system between adjacent thin papers 11 of 5 or more. For example, a thin paper having the same color tone such as red-blue-red is repeated. Even if they are laminated, as shown in 11a to 11g of FIG. 2, thin papers 11 having different color tones may be laminated.

  In addition, in the L * a * b * color system, the thin paper laminate 10 preferably has a difference in L * value of 15 or more between the thin paper having the highest L * value and the thin paper having the lowest L * value. . If the difference in L * value is less than 15, the difference from the dark color to the light color of the thin paper 11 is not clarified and the advertising appeal effect is reduced.

Here, the “L * a * b * color system” referred to in the present invention is a color system defined by CIE (International Lighting Commission) 1976 (JIS Z8729). The “color difference ΔE in the L * a * b * color system” is defined by JIS Z8730 and is obtained by the following equation (1) (hereinafter referred to as “color difference ΔE”). The L * value, a * value, and b * value in the L * a * b * color system can be measured using a color difference meter. Incidentally, L * value is brightness index, a * and b * values are, Delta] E = respectively perceived chromaticity index ^{{(ΔL *) 2 + (} Δa *) 2 + (Δb *) 2} 1 / ² ... (1)
ΔL * = L1 * -L2 *
Δa * = a1 * −a2 *
Δb * = b1 * −b2 *
ΔE: Color difference between thin paper sample 1 and thin paper sample 2 L1 *, a1 *, b1 *: Colorimetric value of thin paper sample 1 L2 *, a2 *, b2 *: Colorimetric value of thin paper sample 2

  The base material of the thin paper 11 is not particularly limited. For example, conventionally, slush pulp in a slurry state produced from chemical pulp obtained by digesting wood chips from hardwood and conifers, and dehydrating and drying the slush pulp The dry pulp and the deinked wastepaper pulp obtained by deinking the used wastepaper can be used alone or in combination. The thin paper 11 is colored by blending a colorant in the raw material pulp, printing with a colorant after papermaking, or using both methods in combination.

  The colorant is not particularly limited, and is generally a direct dye, a cationic dye, a basic dye, an acid dye or the like, which is used for coloring fibers and paper, a natural dye, an edible dye, a dye base or a pigment base. Can be used. Among these, direct dyes, cationic dyes, and pigment-based inks are preferable from the viewpoints of dyeability and weather resistance.

  Examples of direct dyes include anionic direct dyes and cationic direct dyes. Among these, an anionic direct dye is more preferable because it has a large effect of suppressing dyeing property, coloring cost, and color fading to deinked waste paper pulp. When blending dye into raw pulp, adding a cationic softener (cationic paper strength agent if necessary) to the raw pulp and then adding an anionic dye can give a soft texture. preferable.

  The cationic dye is dyed by binding to an acidic group in pulp as a quaternary ammonium compound type cation, and examples thereof include polymethine series, azo series, azamethine series, and anthraquinone series.

  Examples of pigment-based inks include inorganic pigments, organic pigments, and lake pigment inks. From the viewpoint of fixing to deinked waste paper pulp, it is preferable to use an ink of an inorganic pigment.

  When printing after papermaking, it can be applied to one side of the thin paper 11, applied to both sides, or each side can be made to a different color tone. Moreover, it can also give to the whole coloring object surface of the thin paper 11, or can also give it to one part. The effect of the present invention can be obtained if the absolute value of the color difference ΔE in the L * a * b * color system is at least part of the surface of the thin paper 11 adjacent to each other.

  Furthermore, since the thin paper packaging body 1 of the present invention has a structure in which three or more layers of colorful thin paper 11 are laminated, for example, the thin paper 11 can be used as a substitute for origami to make a paper flower. It can be diverted. This makes it easier to attract the interests and interests of children and women, and a greater advertising appeal effect can be expected as compared to ordinary thin paper packaging.

  Although tissue paper is illustrated as the thin paper 11 stored in the thin paper package 1, other types of thin paper 11 may be used, and examples thereof include toilet paper, paper towels, kitchen towels, and wipers. The thin paper 11 may be a single-ply paper of 1 ply, but is preferably a laminated paper of 2 plies or more and 4 plies or less from the viewpoint of water absorption.

The tissue paper as the thin paper 11 is 10 g / m ² or more and 30 g / m ² or less based on JIS P 8124 from the viewpoint of making it difficult to tear when being pulled out from the packaging material 20. The dry strength measured according to 8113 is preferably 60 cN / 25 mm or more and 80 cN / 25 mm or less with respect to the drawing direction. Moreover, it is also preferable to emboss the thin paper 11 from the viewpoint of improving flexibility, sublimation, absorbability, and the like.

  From the viewpoint of improving the recognizability of the color difference ΔE between the thin papers 11, the bulk of the thin papers 11 (paper thickness when the ten thin papers 11 are stacked) is preferably 0.5 mm or more and 1.0 mm or less. From the viewpoint of further improving the recognizability of the color difference ΔE between the thin papers 11, the value obtained by multiplying the bulk (mm) of the thin paper 11 by the number of plies and the number of sets is preferably 2 or more and 20 or less.

  FIG. 4 is a perspective view showing a state in which the thin paper 11 is folded. As shown in FIG. 4 (a), the thin paper 11 is folded in either the short direction or the longitudinal direction, or as shown in FIG. 4 (b). A plurality of folds parallel to each other may be provided along the longitudinal direction and folded along the plurality of folds (see Patent Document 4), but the thin paper 11 is opened or refolded when used. If it can be used as it is, the method of FIG.4 (b) is preferable.

  Further, from the viewpoint of improving the moist feeling, smoothness and flexibility of the thin paper 11, it is also preferable to apply and apply a lotion solution. As this lotion liquid, a known component, for example, a moisturizing agent composed of a polyhydric alcohol such as silicone oil or glycerin, or a softening agent such as a quaternary ammonium salt is blended.

  The base material of the packaging material 20 is not specifically limited. When the thin paper package 1 is a paper box, for example, when using flat paper such as wood pulp, waste paper, corrugated paper, and coated cardboard, coated cardboard is preferable from the viewpoint of strength.

The basis weight of the flat sheet is measured in accordance with JIS P8124, 200g / ^m is preferably ² or more 550 g / ^{m 2} or less, 250 g / ^m, more preferably ² or more 500 g / ^{m 2} or less, 300 g / ^{m 2} or more 500 g / m Most preferred is ² or less. When the basis weight is less than 200 g / m ² , the strength becomes insufficient. On the other hand, when the basis weight exceeds 550 g / m ² , the flat paper is bent to form a three-dimensional shape into the thin paper packaging body 1. Sex is reduced.

  When the thin paper package 1 is a pocket tissue, the base material of the packaging material 20 is a heat-sealable resin film such as a polyethylene film, a polypropylene film, a polyethylene terephthalate film, a polyvinyl alcohol film, a polystyrene film, an ethylene- A vinyl alcohol copolymer film can be mentioned. A linear low-density polyethylene film is preferred because of its high transparency and excellent tearing ability at the perforation 21a. When the packaging material 20 is a resin film, it is preferable to make a haze value into 0.1% or more and 20% or less from a viewpoint of making visibility of the thin paper 11 which is an inclusion good. The thickness of the resin film is preferably 40 μm or more and 80 μm or less. In the case of less than 40 μm, the shape maintaining force of the thin paper laminate 10 is low, and the strength of itself is insufficient. In the case where the thickness exceeds 80 μm, the rigidity and the sealability are deteriorated because the rigidity is too high. The base material of the packaging material 20 is preferably a resin film from the viewpoint of appealing the thin paper 11 to consumers.

  FIG. 5 is a perspective view and a side view showing an embodiment of the thin paper package 1 according to the present invention. When the thin paper package 1 includes the display unit 22 selected from a pattern, a character, a graphic, and the like, the display unit 22 is preferably a display unit 22 in which the thin paper 11 is visible from the outside of the packaging material 20. The visually recognizable display unit 22 is, for example, not printed but transparent, so-called clear (unplugged). When the thin paper 11 is taken out, the color tone of the display unit 22 changes in accordance with the color tone of the thin paper 11, so that the consumer's impression of the thin paper package 1 becomes remarkable. For example, when the thin paper package 1 is used as a novelty, the effect of appealing to consumers can be increased by arranging the name of the advertising target on the display unit 22. When the base material of the packaging material 20 is a flat paper, the display part 22 can be formed by making a part of the base material into a resin film having transparency so that the thin paper 11 can be visually recognized.

  Although the position of the display part 22 is not specifically limited, For example, as shown to Fig.5 (a), it is on the upper surface part of the packaging material 20 (In FIG. 1, the surface side in which the thin paper take-out opening 21 is set as an upper surface part. It is preferable to provide. Furthermore, as shown in FIG.5 (b), by providing the display part 22 in the side surface of the packaging material 20, the laminated thin paper 11 can be visually recognized and a more remarkable beauty | look can be given to a consumer. Although not shown, it is also preferable to store a display member having the display unit 22 printed on the lowermost surface of the thin paper 11 in the packaging material 20 so as to be visible from the surface of the packaging material 20.

  Hereinafter, the present invention will be described more specifically with reference to examples and comparative examples.
