(Function and effect)
The individual package 1 of the absorbent article 10 according to the present embodiment includes the absorbent article 10 and a packaging sheet 20 that individually encloses the absorbent article 10, and is suitable for carrying. Moreover, in this individual package 1, in the outer side area | region M of the packaging sheet 20, 1st coloring part A11 which shows a pattern and / or a symbol, and the 2nd coloring part arrange | positioned in outer side area | regions M other than 1st coloring part A11. A12. That is, 2nd coloring part A12 comprises the background of 1st coloring part A11 which shows a design and / or a symbol. Further, the second colored portion A12 constituting the background is colored in black, and the first colored portion A11 is colored in a color other than black. When the second colored portion A12 is colored in black, the outer region M of the packaging sheet 20 is colored based on black.

  Here, black is a color that hardly transmits external light. In such individual package 1, since the second colored portion A12 constituting the background is colored in black, it is possible to improve the confidentiality of the absorbent article 10 inside the individual package 1.

  Thus, according to the individual package 1 according to this embodiment, it is easy to carry and the confidentiality of the absorbent article 10 accommodated therein can be improved.

  Moreover, in the individual package 1 of the absorbent article which concerns on this embodiment, it is preferable that the total light transmittance in the outer side area | region M of the packaging sheet 20 is 40% or less. When the total light transmittance is 40 or less, the visibility with respect to the internal absorbent article 10 is lowered, and the confidentiality of the internal absorbent article can be improved. In addition, it is preferable that the total light transmittance of the packaging sheet 20 is 0.5% or more. When the total light transmittance of the packaging sheet 20 is less than 0.5%, it is difficult to detect the position of the absorbent article 10 by the optical sensor in the inspection process in which the absorbent article 10 is encapsulated by the packaging sheet 20. This is because there is a possibility of becoming.

  In addition, the second coloring part is a part constituting the background of the packaging sheet, and it is desirable to ensure confidentiality. Therefore, the total light transmittance of the first colored portion is 40% or less, more preferably 30% or less. From the viewpoint of concealment, the total light transmittance is more preferably 10% or less. The packaging sheet may contain a part having a total light transmittance of 30% or less and a bulk softness of 0.1N or more, which will be described later, for the purpose of improving design properties. It is desirable to be configured not to include 40% or more of the outer region of the packaging sheet. More preferably, the portion that does not satisfy the condition is preferably less than 30%. Moreover, it is preferable that a 1st coloring part is 0.5% or more for laser beam transmission.

  Moreover, in the individual package 1 of the absorbent article which concerns on this embodiment, since the bulk softness of the packaging sheet 20 is 0.17N or more, it becomes difficult to produce the relief | undulation by the shape of an absorbent article in the outer area | region of a packaging sheet. Therefore, the confidentiality of the internal absorbent article is improved. In addition, it is preferable that the bulk softness of the packaging sheet 20 is smaller than 2.0N. This is because if the bulk softness of the packaging sheet 20 is 2.0 N or more, the packaging sheet 20 becomes difficult to fold, and therefore, there may be a problem in the folding process during manufacturing.

  In the present embodiment, the region colored by the first coloring portion A11 and the second coloring portion A12 is the entire region of the packaging sheet 20. That is, since there is no part which is not colored in packaging sheet 20, the visibility to internal absorptive article 10 can be reduced reliably. Therefore, the confidentiality with respect to the internal absorbent article 10 can be further enhanced. In particular, when the packaging sheet 20 and the absorbent article 10 are folded and the absorbent article 10 is enclosed by the packaging sheet 20, an overlapping part is provided on the folded packaging sheet so that the absorbent article inside is overlapped by the overlapping part. It can be more difficult to see. That is, since it can be difficult to grasp that the absorbent article 10 is inside the individual package 1, confidentiality can be improved.

  In the individual packaging body 1 of the absorbent article according to the present embodiment, the packaging sheet 20 and the absorbent article 10 are folded in a state where the absorbent article 10 is placed on the packaging sheet 20, and the inside of the packaging sheet 20. The absorbent article 10 is included. Moreover, since the packaging sheet 20 overlaps when the absorbent article 10 and the packaging sheet 20 are folded, the visibility of the internal absorbent article 10 by the packaging sheet 20 is suppressed, and confidentiality is increased. Moreover, the thickness of the individual package 1 can be adjusted by folding the absorbent article 10 and the packaging sheet 20.

  In the present embodiment, the length WA of the individual package 1 in the first direction W1 is shorter than the length LA of the individual package 1 in the second direction L1. Thereby, it is easier to fit in the hand and easier to carry than when the respective lengths are equal. The ratio of the length WA in the first direction W1 of the individual package 1 to the length LA in the second direction L1 of the individual package 1 is preferably 0.51 or less. If it becomes such a ratio, it will become difficult to recognize as the absorbent article 10. FIG. That is, since it becomes difficult to visually recognize when the absorbent article 10 is included in the individual package 1, confidentiality is improved.

  In the individual package 1 of the absorbent article according to the present embodiment, the total light transmittance in the first colored portion A11 is preferably higher than the total light transmittance in the second colored portion A12. Moreover, as shown in FIG. 1, it is preferable that 1st coloring part A11 is continuously provided in the 2nd direction L1 of the individual package 1 from one edge part 20E1 to the other edge part 20E2.

  In this case, since the first colored portion A11 is provided continuously from one end portion 20E1 to the other end portion 20E2 in the longitudinal direction L1 (second direction) of the individual package, an individual using an optical sensor. In the inspection process for inspecting the distortion or omission of the absorbent article in the package 1, inspection accuracy can be ensured.

  Specifically, FIGS. 5 to 6 are perspective views schematically showing the inspection process of the individual package 1. FIG. 5 shows a continuous body of the individual packaging body 1 before being folded, that is, a continuous body of the individual packaging body 1 in an unfolded state. On the other hand, FIG. 6 shows a continuous body of the individual package 1 after being folded, and the individual package 1 is manufactured by individually cutting the continuous body of the individual package 1.

  As shown in FIGS. 5 to 6, the inspection process includes an inspection of the individual package 1 in a state before being folded and an inspection of the individual package 1 in a state after being folded.

  In the inspection process, the inspection lights R1 to R3 emitted from the optical sensor are continuously applied to the continuous body of the individual package 1 being conveyed in the conveyance direction (MD). Therefore, while conveying the longitudinal direction L1 (second direction) of each individual package 1 in the conveyance direction, it is emitted from the optical sensor to the first colored portion A11 that is continuously provided in the outer region M of each individual package 1. The inspection lights R1 to R3 are irradiated. At this time, the first colored portion A11 takes into consideration the confidentiality, sets the total light transmittance at which the absorbent article 10 inside the individual package 1 cannot be visually recognized from the outside, and transmits the inspection lights R1 to R3. Set to light transmittance.

  Thereby, the inspection lights R1 to R3 of the optical sensor can reach the absorbent article 10 inside the individual package 1, and the position or presence of the absorbent article 10 inside the individual package 1 can be detected with higher accuracy.

  In such an inspection process, for example, as shown in the drawing, the state of the absorbent article 10 in the individual package bodies C11 to C12 before being folded is normal, and the absorbent article 10 in the individual package body C13 is normal. It is possible to detect that the state of is distorted and abnormal. Similarly, as shown in FIG. 6, the state of the absorbent article 10 in the individual package bodies C11 to C12 after being folded is normal, and the absorbent article 10 in the individual package body C13 is in a normal state. It can be detected that the state is distorted and abnormal. In this way, by prescribing the total light transmittance of the first colored portion A11, the accuracy of inspection at the time of manufacturing the individual package 1 is improved and the quality of the individual package 1 is improved while ensuring secrecy. Can do.

  In addition, also in 2nd coloring part A12, considering confidentiality, it is set as the total light transmittance which cannot visually recognize the absorbent article 10 in the inside of the individual package 1 from the outside, and all which permeate | transmit inspection light R1 thru | or R3. The light transmittance may be set. In this case, even if the inspection light R1 to R3 of the optical sensor is irradiated on either the first colored portion A11 or the second colored portion A12, the absorbent article 10 is more distorted or removed from inside the individual package 1. It can be detected with high accuracy.

  The packaging sheet 20 may be configured in a bag shape. For example, the packaging sheet 20 may have a bag-like configuration in which two side end portions and a bottom portion of two stacked sheets are joined and one opening portion is provided. According to this configuration, when the used absorbent article is stored in the packaging sheet 20, the used absorbent article is difficult to be exposed and easily stored.

Specifically, the number of people A who answered “not visible at all”, the number of people B who answered “slightly visible”, the number of people C who answered “can not say either”, the number of people D who answered “somewhat invisible”, “ The number of people A to E was counted as the number of people E who answered “I can see clearly”.

  As a visibility index value, a ratio of “not visible”: “visible” was calculated as X: Y. Specifically, the X value “not visible” is calculated by X = (A + B + C × 1/2) / (A + B + C + D + E), and the Y value “visible” is calculated as Y = (D + E + C × 1/2) / ( (A + B + C + D + E).

  In this evaluation, a value in which “X: Y”, which is a ratio of “not visible”: “visible”, is “50:50” or more is defined as a passability evaluation pass line.

  Next, in each of Examples 1 to 6 and Comparative Examples 1 and 2, a sample of the packaging sheet was cut out, and the total light transmittance was measured using a cross side light type color difference meter. The sample size was 35 mm square. The measurement part of Examples 1-6 was made into the black part (2nd coloring part) colored black, and the measurement part of Comparative Examples 1-2 was made into the other color part colored other colors other than black.

表１に示すように、実施例１〜６に係る個包装体は、「視認できない」：「視認できる」の比率である「Ｘ：Ｙ」が、「５０：５０」以上であり、個包装体に内包される吸収性物品に対する視認性を抑制する効果に優れていることがわかった。一方、比較例１〜２に係る個包装体は、「Ｘ：Ｙ」が、「５０：５０」以下であり、個包装体に内包される吸収性物品に対する視認性を抑制する効果が低いことがわかった。当該結果から、全光線透過率が、２８．３％以下であれば、視認性が低下することが確認された。すなわち、包装シートに内包される吸収性物品の秘匿性を高めることができることが確認された。 (Measurement result)
The measurement results are shown in Table 1.

As shown in Table 1, the individual packages according to Examples 1 to 6 have “X: Y”, which is a ratio of “not visible”: “visible”, of “50:50” or more, and are individually packaged. It turned out that it is excellent in the effect which suppresses the visibility with respect to the absorbent article included in a body. On the other hand, the individual packaging bodies according to Comparative Examples 1 and 2 have “X: Y” of “50:50” or less, and the effect of suppressing the visibility of the absorbent article contained in the individual packaging body is low. I understood. From the results, it was confirmed that the visibility was lowered when the total light transmittance was 28.3% or less. That is, it was confirmed that the secrecy of the absorbent article included in the packaging sheet can be improved.

  Furthermore, in the individual package according to Examples 1 and 2, if “X: Y” is “90:10” or more and the total light transmittance is 4.51% or less, the visibility is greatly increased. It decreased, and it was confirmed that the secrecy of an absorbent article can be improved more.

(2) Evaluation of visibility based on bulk softness (evaluation method)
Individual packaging bodies according to Examples 11 to 16 and Comparative Examples 11 to 12 were prepared. Specifically, individual packaging bodies having packaging sheets with different bulk softness were prepared as individual packaging bodies according to Examples 11 to 16 and Comparative Examples 11 to 16.

  Whether it can be grasped that it is an absorptive article from the undulation which floats on the packaging sheet by the absorptive article included in the individual wrapping body using the individual wrapping bodies according to Examples 11 to 16 and Comparative Examples 11 to 12 The sensory test was conducted.

  The sensory test allows 10 persons to visually observe the individual package bodies according to Examples 11 to 16 and Comparative Examples 11 to 12, and is included in the package body in the same manner as the visibility evaluation based on the total light transmittance described above. It was made to answer in 5 steps whether the absorbent article which can be visually recognized. Then, in the same manner as the evaluation of the visibility based on the total light transmittance described above, the number of persons A to E was counted, and the ratio of “not visible”: “visible” was calculated as X: Y.

  In this evaluation as well, a value in which “X: Y”, which is a ratio of “not visible”: “visible”, is “50:50” or more is defined as a passability evaluation pass line.

  Next, in each of Examples 11 to 16 and Comparative Examples 11 to 12, a packaging sheet was cut out and prepared as follows. First, a sheet piece was prepared by cutting into a size of 100 mm × 15 mm (100 mm along the longitudinal direction of the packaging sheet and 15 mm in the width direction).

  Next, the sheet piece was rolled into a cylindrical shape (only 1 roll). At this time, the sheet piece was rounded so that the width direction of the sheet piece would be the height direction (axial direction) of the cylinder. Further, when rounded, the seam (the overlap width was 10 mm) was fixed with two upper and lower staples, and this was used as a sample.

  Next, the maximum load when the sample was compressed from the height direction (axial direction) of the cylinder under the following conditions was measured. In addition, each measurement result was made into the average value of 5 times of measured values.

表２に示すように、実施例１１〜１６に係る個包装体は、「視認できない」：「視認できる」の比率である「Ｘ：Ｙ」が、「５０：５０」以上であり、個包装体に内包される吸収性物品に対する視認性を抑制する効果に優れていることがわかった。一方、比較例１１〜１２に係る個包装体は、個包装体に内包される吸収性物品「Ｘ：Ｙ」が、「５０：５０」以下であり、個包装体に内包される吸収性物品に対する視認性を抑制する効果が低いことがわかった。当該結果から、バルクソフトネスが、０．１７Ｎ以上であれば、吸収性物品の視認性が極めて低下することが確認された。すなわち、個包装体において、包装シートに内包される吸収性物品の秘匿性を高めることができることが確認された。 <Measurement conditions>
・ Compression tester: Tensilon tensile tester (used in compression mode)
・ Compression speed: 10mm / min
(Measurement result)
The measurement results are shown in Table 2.

As shown in Table 2, the individual packages according to Examples 11 to 16 have an “X: Y” ratio of “not visible”: “visible”, and “50:50” or more, and are individually packaged. It turned out that it is excellent in the effect which suppresses the visibility with respect to the absorbent article included in a body. On the other hand, in the individual package according to Comparative Examples 11 to 12, the absorbent article “X: Y” included in the individual package is “50:50” or less, and the absorbent article included in the individual package. It turned out that the effect which suppresses the visibility with respect to is low. From the result, it was confirmed that the visibility of the absorbent article is extremely lowered when the bulk softness is 0.17 N or more. That is, it was confirmed that the confidentiality of the absorbent article included in the packaging sheet can be enhanced in the individual package.

  Furthermore, in the individual package according to Examples 1 and 2, if “X: Y” is “95: 5” or more and the bulk softness is 0.58 N or more, the visibility is greatly reduced. It was confirmed that the confidentiality of the absorbent article can be further improved.
