(First embodiment)
With reference to FIGS. 1-5, the package 100 of the absorbent article which concerns on 1st Embodiment is demonstrated. FIG. 1 is a plan view of the absorbent article package 100 as viewed from the skin contact surface side, and FIG. 2 is a rear view of the absorbent article package. As shown in FIGS. 1 and 2, an absorbent article packaging body 100 includes an absorbent article 1 and a packaging sheet 70 for individually packaging the absorbent article 1. The absorbent article 1 according to the present embodiment is, for example, a sanitary napkin.

In the package 100 of the absorbent article 1, the absorbent article 1 is individually wrapped by folding the packaging sheet 70 and the absorbent article 1 in a state where the absorbent article 1 is disposed on the packaging sheet 70. Yes. FIG. 4A is a plan view of a state in which the absorbent article 1 is individually packaged by the packaging sheet 70.

The absorbent article 1 includes a top sheet 10 that comes into contact with the wearer's skin, a liquid-impermeable back sheet 20 that does not transmit liquid, and an absorber 30. The absorber 30 is disposed between the top sheet 10 and the back sheet 20. Therefore, the absorber 30 is shown with a broken line in FIG. The absorbent body 30 is disposed at the central portion in the longitudinal direction L and the width direction W of the absorbent article 1. In addition, the absorbent article 1 may be provided with a wing part or a hip flap part provided on the outer side in the width direction of the absorbent body 30.

The top sheet 10 is a liquid-permeable sheet that transmits liquid such as body fluid. The top sheet 10 covers at least the surface of the absorber 30. The top sheet 10 is not particularly limited as long as it is a sheet-like material having a structure that allows liquid to permeate, such as a nonwoven fabric, a woven fabric, a perforated plastic sheet, and a mesh sheet. Either natural fibers or chemical fibers can be used as the woven or non-woven material.

The back sheet 20 has substantially the same length as the top sheet 10. The back sheet 20 may be a film mainly composed of polyethylene, polypropylene, or the like, a breathable resin film, a sheet obtained by bonding a breathable resin film to a nonwoven fabric such as spunbond or spunlace. The back sheet 20 is preferably made of a material having flexibility that does not cause a sense of incongruity when worn.

The absorber 30 includes hydrophilic fibers and pulp. The absorber 30 may be formed by laminating hydrophilic fibers or powder by the airlaid method, or may be an airlaid sheet obtained by forming hydrophilic fibers or powder into a sheet shape by the airlaid method.

In the absorbent article 1, the periphery of the top sheet 10 and the back sheet 20 is joined, and the absorber 30 is enclosed. As a method for joining the top sheet 10 and the back sheet 20, any one or a combination of heat embossing, ultrasonic waves, and hot melt can be used.

In the back sheet 20, the adhesive material 81 is applied to the surface (non-contact surface) that contacts the shorts. The area where the adhesive material is applied becomes an adhesion area. In a state before use, a release sheet 79 for maintaining the adhesiveness is bonded to the adhesive material.

The release sheet 79 is bonded to the packaging sheet 70 via an adhesive (not shown). Since the release sheet 79 and the packaging sheet 70 are bonded, the absorbent article 1 and the release sheet 79 are separated by opening the packaging sheet 70 and separating the absorbent article 1 and the packaging sheet 70. Therefore, even if the wearer is not aware of the work of peeling the release sheet 79 from the absorbent article, the wearer can easily wear the absorbent article 1 by exposing the adhesive material to the surface of the back sheet. Can do.

FIG. 4B is a schematic enlarged view of a portion A in FIG. 4A, and FIG. 4C is a schematic cross-sectional view of the packaging sheet. The top sheet 10 is provided with a plurality of pressing grooves (squeezing portions) 21. The pressing groove 21 is configured by pressing the surface sheet 10 to the absorber 30 in the thickness direction. In the present embodiment, the squeezing groove 21 is squeezed by embossing.

The packaging sheet 70 wraps the absorbent article 1 individually. The packaging sheet 70 has an inner surface 71 disposed on the absorbent article side and an outer surface 72 positioned on the outer side in a state where the absorbent article 1 is accommodated. The inner surface 71 of the packaging sheet 70 faces the absorbent article 1 on the back sheet 20 side of the absorbent article 1.

When individually packaging the absorbent article 1 with the packaging sheet 70, the absorbent article 1 is arranged on the inner surface of the packaging sheet 70, with the topsheet 10 of the absorbent article 1 facing inward and along the width direction W. The first fold line F1 and the second fold line F2 are folded as base points.

Specifically, for example, in a state where the absorbent article is disposed on the inner surface of the packaging sheet 70, the absorbent article 1 and the packaging sheet 70 are folded based on the first fold F1 as shown in FIG. Next, the absorbent article 1 and the packaging sheet 70 are folded using the second fold F2 as a base point. Then, one end of the packaging sheet 70 in the longitudinal direction L is stuck to a part of the packaging sheet 70 with the adhesive tape 75. Furthermore, the adhesive article 1 can be individually packaged by the packaging sheet 70 as shown in FIG. 4A by adhering both side ends of the packaging sheet 70 in the width direction W by heat welding or the like. The portion to be heat-welded is a hatched area in FIG.

Next, the packaging sheet 70 will be described in detail. The packaging sheet 70 is formed by laminating a meltblown nonwoven fabric layer 73 constituting an inner surface 71 on the absorbent article side and a spunbond nonwoven fabric layer 74 positioned outside the meltblown nonwoven fabric layer 73 in the thickness direction T of the absorbent article 1. It is comprised by the laminated body made. The melt blown nonwoven fabric layer 73 is provided with a printing unit 76.

The printed part 76 is provided in the melt blown nonwoven fabric layer 73 located on the inner surface 71 side of the packaging sheet 70, and the spunbond nonwoven fabric layer 74 is provided outside the melt blown nonwoven fabric layer 73. The printing unit 76 is configured so that the printing unit 76 can be viewed from the outside of the packaging sheet 70 through the spunbond nonwoven fabric layer 74 in a state where the absorbent article 1 is individually packaged by the packaging sheet 70. .

Since the absorbent article 1 is covered with a laminate composed of a plurality of nonwoven fabric layers while being wrapped by the packaging sheet 70, the absorbent article 1 is concealed by the fibers constituting the nonwoven fabric layers. Therefore, when another person visually recognizes the package of the absorbent article, it can be difficult to discriminate it from the absorbent article at first glance. Moreover, since the printing part 76 is provided in the packaging sheet 70, decorativeness becomes high, and when other person visually recognizes the package body of an absorbent article, it can be made hard to distinguish from an absorbent article.

When users carry an absorbent article, they often do not want to be aware that someone else has the absorbent article. According to the package of the absorbent article, the internal absorbent article is difficult to visually recognize and the outer surface has high decorativeness, so it is difficult to distinguish it from the absorbent article, and when the user carries the absorbent article, It is possible to reduce the psychological burden of being aware of being an absorbent article.

The melt-blown nonwoven fabric layer 73 is a short fiber and has a thin fiber diameter in order to draw resin from the spinning nozzle with hot air and collect the fiber. In general, the fibers constituting the meltblown nonwoven fabric layer 73 have a smaller fiber diameter and a shorter fiber length than the fibers constituting the spunbond nonwoven fabric layer 74. Therefore, the coloring component of the printing unit 76 easily enters between the fine fibers and easily penetrates into the melt blown nonwoven fabric layer 73, and maintains the colored state. Moreover, since the melt blown nonwoven fabric layer 73 has a higher density than the spunbond nonwoven fabric layer 74, the colored components can be finely arranged and a fine pattern can be expressed.

The printing unit 76 is provided on the melt blown nonwoven fabric layer 73 on the inner surface side of the packaging sheet 70. Since the printing part 76 is provided in the melt blown nonwoven fabric layer 73 having a relatively high density, it is possible to suppress the coloring component of the printing part 76 from being exposed to the outer surface 72 side. The absorbent article packaging body 100 is often carried in a bag or the like. For example, if the printing unit 76 is disposed on the outer surface 72 side, the coloring component of the printing unit 76 may be peeled off and adhere to another container in the bag. However, color transfer can be suppressed by providing the printing unit 76 on the inner surface 71 side of the packaging sheet 70.

The spunbond nonwoven fabric layer 74 is a long fiber and has a relatively large fiber diameter because it cools the resin from the spinning nozzle and directly collects the fibers to form a nonwoven fabric. In general, the fibers of the spunbond nonwoven fabric layer 74 have a larger fiber diameter and a longer fiber length than the fibers constituting the meltblown nonwoven fabric layer 73. Therefore, even if the spunbond nonwoven fabric layer disposed on the outer side of the packaging sheet 70 is rubbed, fraying of the fibers can be suppressed and the fiber orientation state can be easily maintained. The spunbond nonwoven fabric layer 74 has a lower density than the meltblown nonwoven fabric layer 73, easily transmits light, and does not easily diffuse light. Therefore, even from the outside of the packaging sheet 70, the printing unit can be easily recognized.

Note that the printing unit 76 has a heart-like dot shape in plan view, and a plurality of the printing units 76 are intermittently arranged. In addition, the dot shape in this embodiment is not only a circular shape but also a heart shape, a triangle shape, an ellipse shape, etc. as in this embodiment, and is a fine pattern shape, which is intermittently plural. The shape to be arranged is included.

The printing unit 76 is provided by, for example, flexographic printing, gravure printing, screen printing, inkjet printing, or laser printing. The printing unit 76 may be provided by printing from the inner surface 71 side of the meltblown nonwoven fabric layer 73 in a state where the meltblown nonwoven fabric layer 73 and the spunbond nonwoven fabric layer 74 are laminated. The melt blown nonwoven fabric layer 73 that has not been printed may be printed.

For example, by coloring the melt-blown nonwoven fabric layer 73 and the spunbond nonwoven fabric layer 74 in an overlapping state, the melt-blown nonwoven fabric layer 73 and the spunbond nonwoven fabric layer 74 are separately manufactured and laminated. Reduction in efficiency can be suppressed. Moreover, when printing is performed from the meltblown nonwoven fabric layer 73 side, the coloring component remains in the meltblown nonwoven fabric layer 73 having a relatively high density. Therefore, it can suppress that a coloring component passes to the surface (outer surface) opposite to the side which performs printing, and can prevent the color omission at the time of printing.

Furthermore, since the packaging sheet 70 is composed of a plurality of non-woven fabric layers and does not include a film, it can maintain a good texture as compared to a packaging sheet made of a resin film, and generates a sound when opened. Inconveniences such as outing can be suppressed.

Furthermore, when a thermoplastic resin layer and a nonwoven fabric layer having different materials are used as in a conventional packaging sheet, a process such as bonding the layers to each other is required, which may increase the manufacturing process. However, an increase in the manufacturing process can be suppressed by configuring the packaging sheet with a nonwoven fabric layer made of the same material.

The packaging sheet 70 is formed with an embossed portion 77 for the purpose of improving the texture (see FIG. 4B). In the embossed portion 77, the packaging sheet 70 is compressed in the thickness direction. The embossed portions 77 are circular and are arranged intermittently. The packaging sheet 70 is provided with an embossed portion 77 that has been embossed and a non-embossed portion 78 that has not been embossed. Since the embossed portion 77 has a higher density than the non-embossed portion 78, the color of the printed portion 76 tends to be dark. Therefore, if the printing unit 76 is disposed across the embossed unit 77 and the non-embossed unit 78, the color density of the printing unit 76 may be uneven.

The interval S1 between the embossed portions 77 of the packaging sheet 70 according to the present embodiment is configured to be longer than the width S2 of the printed portion. Therefore, the probability that the printing unit 76 is disposed across the embossed part 77 and the non-embossed part 78 can be reduced, and the density of the printing unit 76 can be made to be uniform. Furthermore, by arranging the printing part 76 only in the non-embossed part 78 or by arranging the printing part 76 only in the embossed part 77, the density of the printing part 76 can be made more uniform.

Further, the embossed portion 77 is formed by passing between an embossed roll having irregularities formed thereon and a roll having a smooth outer peripheral surface, which is disposed to face the embossed roll. A portion pressed by the unevenness of the embossing roll becomes an embossed portion 77, and a portion not pressed by the unevenness of the embossing roll becomes a non-embossed portion 78.

Moreover, since the embossed portion formed in this way is formed by being pressed in the thickness direction, it is recessed from one surface to the other surface. The embossed part may be formed from the side of the spunbond nonwoven fabric layer inside the packaging sheet, or may be formed from the side of the spunbond nonwoven fabric layer outside the packaging sheet.

Since the embossed part has a higher density than the non-embossed part and is thinner than the non-embossed part, the shade of the color becomes uneven in the printed part of the embossed part and the printed part of the non-embossed part. There is. However, at least a spunbonded nonwoven fabric layer positioned on the outer side in the thickness direction than the melt blown nonwoven fabric layer is disposed on the outer side in the thickness direction than the printing portion. Since the user visually recognizes the printed portion through the spunbonded nonwoven fabric layer having a certain thickness, the difference in density due to the presence or absence of embossing is less noticeable.

Furthermore, in the structure in which the embossed part is formed from the side of the spunbond nonwoven fabric layer inside the packaging sheet, the unevenness of the embossed part is difficult to visually recognize from the outside of the packaging sheet, so that the density due to the presence or absence of embossing becomes even less noticeable. .

Further, in the package 100 of the absorbent article, the end of the packaging sheet 70 is attached to the surface of the packaging sheet 70 with the adhesive tape 75 in a state where the absorbent article 1 is wrapped by the packaging sheet 70. In the process of manufacturing the absorbent article package 100, the adhesive tape 75 is detected by an inspection device, and it is inspected whether the adhesive tape 75 is correctly applied.

The detection of the adhesive tape 75 is performed by, for example, imaging the absorbent article packaging body 100 and measuring the position and shape of the adhesive tape from the image information. At this time, if the color of the adhesive tape is close to the color of the packaging sheet, the adhesive tape 75 may be erroneously detected.

Therefore, it is preferable that the color difference of the adhesive tape and the color difference of the packaging sheet are different, specifically, 14.54 or more are desirable. Due to the large difference between the color difference of the adhesive tape and the color difference of the packaging sheet, the distinguishability of the adhesive tape is enhanced and the adhesive tape is easily detected. The packaging sheet includes a region where the printing unit 76 is provided and a region where the printing unit 76 is not provided. Therefore, it is desirable that both the color difference of the printing unit 76 and the color difference of the melt blown nonwoven fabric layer 73 located on the outer side in the thickness direction of the packaging sheet differ from the color difference of the adhesive tape 75 by 14.54 or more.

The color difference of the adhesive tape in the present embodiment is the color difference of the adhesive tape with respect to the white reference plate (Y = 95.09, X = 93.06, Z = 112.00), and the color difference of the packaging sheet is the white reference plate (Y = 95.09). , X = 93.06, Z = 112.00). Specific examples will be described in detail later.

Further, when the absorbent article package 100 configured as described above is discarded after the absorbent article 1 is used, the absorbent article 1 is often disposed in a state of being wrapped by the packaging sheet 70. FIG. 5 is a view showing a disposal state after use of the package of absorbent articles. (A) is a perspective view, (b) is a top view of the package of the absorbent article shown in (a).

After the absorbent article 1 is used, in order to prevent menstrual blood or the like from adhering to the surroundings, the absorbent article 1 is rolled up so that the topsheet 10 is inside, and then the absorbent article 1 is removed by the packaging sheet 70. Can be wrapped. At this time, the packaging sheet 70 is overlapped around the absorbent article 1 and the printing unit 76 of the packaging sheet 70 is also overlapped. Since the printing part 76 of the packaging sheet 70 located on the inner side and the printing part 76 of the packaging sheet 70 located on the outer side overlap, the printing part is arranged in a three-dimensional manner and a three-dimensional effect can be obtained.

Furthermore, the printing part 76 of the packaging sheet 70 located on the inner side and the printing part 76 of the packaging sheet 70 located on the outer side are often arranged so as not to coincide with each other. Therefore, the printing unit 76 can be arranged in a scattered manner, the ratio of the area where the printing unit is arranged to the area where the printing unit 76 is not provided can be increased, and the concealment and decoration can be further improved.

(Second Embodiment)
With reference to FIG. 6, the package 101 of the absorbent article which concerns on 2nd Embodiment is demonstrated. In the description of the second embodiment, a configuration different from that of the first embodiment will be described, and the description of the same configuration will be omitted by using the same reference numerals. FIG. 6 is a view showing a package for absorbent articles according to the second embodiment. (A) is a top view, (b) is a model enlarged view of B part shown to (a), (c) is a schematic cross section of a packaging sheet.

The absorbent article packaging body 101 according to the second embodiment is compared with the absorbent article packaging body according to the first embodiment, the structure of the laminated body constituting the packaging sheet, and the arrangement pattern of the printing unit. And are different.

The printing unit 76 of the packaging sheet 70 according to the second embodiment is linear, and a plurality of the printing units 76 are intermittently arranged in parallel. Also when the absorbent article 1 after use is wrapped with the packaging sheet 70 by the plurality of linear printing parts 76 arranged intermittently, the printing parts 76 can be arranged so as to overlap each other, thereby improving the decorativeness. Can do.

Further, as shown in FIG. 6B, the width S2 of the printing unit 76 is shorter than the interval S1 of the embossed unit 77, and the printing unit 76 is easily disposed only in the non-embossed unit 78. The probability that the printing unit 76 is arranged across the embossed part 77 and the non-embossed part 78 can be reduced, and the density of the printing unit 76 can be made to be uniform.

The packaging sheet 70 is provided with a spunbond nonwoven fabric layer 74 inside the melt blown nonwoven fabric layer 73 in the thickness direction T of the absorbent article 1. That is, the packaging sheet 70 is constituted by two spunbond nonwoven fabric layers 74 and a meltblown nonwoven fabric layer 73 disposed therebetween. The printing unit 76 is provided on the inner spunbond nonwoven fabric layer 74 and the meltblown nonwoven fabric layer 73.

By sandwiching the meltblown nonwoven fabric layer 73 with the spunbond nonwoven fabric layer 74, the surface (the inner surface 71 and the outer surface 72) of the packaging sheet 70 becomes the spunbond nonwoven fabric layer 74, and the fraying when the surface of the packaging sheet 70 is rubbed is suppressed. The texture can be maintained.

Also, it is desirable that the spunbond nonwoven fabric layer disposed outside the packaging sheet has a higher basis weight than the spunbond nonwoven fabric layer disposed inside the packaging sheet. For example, the spunbond nonwoven fabric layer arranged on the outside of the packaging sheet may be composed of a single layer, the basis weight of the single layer of the spunbond nonwoven fabric layer may be increased, or the spunbond nonwoven fabric arranged on the outside of the packaging sheet You may comprise a layer by comprising in multiple layers so that a fabric weight may be made higher than the spunbond nonwoven fabric layer arrange | positioned inside. Thus, by raising the basis weight of the spunbond nonwoven fabric layer outside the packaging sheet, fraying of the fibers constituting the nonwoven fabric layer can be prevented even when the outside of the packaging sheet is rubbed.

As a specific configuration of the packaging sheet, for example, a spunbond nonwoven fabric layer having a basis weight of 4.4 g / m ² is arranged on the inner side of the packaging sheet, and a melt blown nonwoven fabric layer having a basis weight of 1.9 g / m ² is provided on the outer side of this layer. A configuration in which two spunbond nonwoven fabric layers having a basis weight of 4.4 g / m ² are arranged outside the layer can be exemplified. According to the packaging sheet thus configured, the outer side of the packaging sheet becomes bulky, and even if the spunbond nonwoven fabric layer disposed on the outer side of the packaging sheet 70 is rubbed, fraying of the fibers can be suppressed, and the fiber orientation state can be changed. Easy to maintain.

Further, in order to make the printed layer visible from the outside of the packaging sheet, the basis weight of the packaging sheet is desirably 18 g / m ² or less, and the basis weight of the meltblown nonwoven fabric layer is 1.2 g / m ² or more. Therefore, it is desirable that it is 2.7 g / m ² or less.

As described above, the contents of the present invention have been disclosed through the embodiments of the present invention. However, it should not be understood that the description and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples and operational techniques will be apparent to those skilled in the art.

For example, a colored decorative portion may be provided on the surface of the release sheet disposed between the packaging sheet and the adhesive portion of the absorbent article on the side of the packaging sheet. By configuring so that the decorative part can be visually recognized through the packaging sheet from the outside of the packaging body of the absorbent article, the printing part of the packaging sheet, the decorative part of the release sheet, the decorative part of the release sheet, and the packaging sheet It is possible to enhance the decoration effect by displaying the print section in an overlapping manner.

Further, a pigment may be kneaded into fibers constituting the meltblown nonwoven fabric layer or fibers constituting the spunbond nonwoven fabric layer. By kneading the pigment into the fibers constituting the meltblown nonwoven fabric layer or the fibers constituting the spunbond nonwoven fabric layer, each layer can be colored in the process of producing the meltblown nonwoven fabric layer, and the decorative effect can be further enhanced.

Furthermore, the absorbent article is not limited to a sanitary napkin as long as it is individually packaged by a packaging sheet, and various configurations such as an absorbent pad, a disposable diaper, and a sanitary tampon can be adopted.

Hereinafter, the detection evaluation of the adhesive tape will be described in detail with examples. In addition, this invention is not limited by these.

(Evaluation content)
In the state which stuck the adhesive tape which concerns on embodiment to the packaging sheet, the applicability of the detection of an adhesive tape was evaluated.

(Evaluation methods)
Whether adhesive tape is applied to samples of packaging sheets according to Examples 1 to 6 and Comparative Examples 1 to 3 and passed through a camera-type sensor at a speed of 200 mm / min. It was evaluated whether it was detected as a defective product without being detected as an adhesive tape (not detectable).

Moreover, the color difference with respect to a white reference board was measured about the sample of the packaging sheet, and the adhesive tape. A pink tape was used as the adhesive tape to be measured. The measurement target packaging sheet was an SMS nonwoven fabric having a basis weight of 15 g / m ² . The ink density and the number of stacked sheets were varied for each packaging sheet.

(Color difference measurement conditions)
Measuring device: NIPPON DENSHOKU Color Meter ZE2000
White standard plate: Y = 95.09, X = 93.06, Z = 112.00
(Measurement method of color difference)
First, the measuring device is turned on and left for 15 minutes to ensure stable operation of the device. Next, the measurement method “reflection” is selected, and “white standard plate (Y = 95.09, X = 93.06, Z = 112.00)” is selected. Then, zero alignment and standard alignment are performed. Zero alignment is performed by placing a zero cap and pressing “0-ADJ”, and standard alignment is performed by pressing “S-ADJ” with a standard plate set on the sample stage. .

Next, the object to be measured (packaging sheet or adhesive tape) is placed on the sample stage on which the 6φ hole is formed. At this time, the non-printing surface side to be measured is set as the sample stage side. Next, a white reference plate is placed on the measurement target. In this state, the color difference is measured by setting a viewing hole in which a 6φ hole is formed on the measuring device from the surface of the sample table opposite to the object to be measured. The number of samples of each measurement object was 2, and the average value was used.

(Measurement result)
The measurement results are shown in Table 1.

The packaging sheets according to Examples 1 to 6 were able to detect the adhesive tape affixed to the packaging sheet with a sensor. On the other hand, in the packaging sheets according to Comparative Examples 1 to 3, the adhesive tape attached to the packaging sheet could not be detected by the sensor. From the result, it was found that if the difference between the color difference of the adhesive tape and the color difference of the packaging sheet is 14.54 or more, the adhesive tape can be detected in the production process.
