Here, assuming that the direction from the front body portion to the back body portion is the front-back (up-down) direction and the direction orthogonal to the front-back (up-down) direction is the left-right direction, the absorber 22 of the present embodiment has a length in the front-back (up-down) direction and a left-right direction. (In FIGS. 2 and 3, the front-back (up-down) length is longer than the left-right length). The shape of the absorber 22 of the present embodiment is not limited to this, and for example, a substantially square shape having the same front-rear (up-down) left-right length and a rounded front-back (up-down) end corner. , Includes various shapes such as elliptical ones extending back and forth (up and down), circular ones, etc. Further, a pair of left and right notches forming a rectangular shape such as an arc shape or a trapezoidal shape may be formed in the inseam portion of the absorber 22 so as to correspond to the pair of leg-circumferential openings 12. In the diaper 10 according to the present embodiment, the absorbent body 22 wrapped with the covering member 22b is used, but the absorbent article according to the present invention absorbs the absorbent core 22a not wrapped with the covering member 22b. It may be used as a body 22.

In the present embodiment, a plurality of recesses 25 are formed in the absorber, and the plurality of recesses 25 form a lattice pattern as a whole. Specifically, as shown in FIGS. 2 and 3, the plurality of recesses 25 are formed so as to extend in an oblique lattice pattern on the surface of the absorber 22. As shown in FIGS. 1 to 4, the formation of the recess 25 makes it easier to bend in the recess 25, and it is possible to improve the fit of the diaper 10. Further, by continuously forming the recess 25, air can pass through to the ventral side or the dorsal side, and air permeability can be ensured. Further, the discharged body fluid can be rapidly diffused, and the absorber 22 can be used as a whole to be efficiently absorbed by the absorber 22.

An adhesive is applied to the surface where the top sheet 21 and the absorber 22 are in contact with each other, and the recess 25 is formed by, for example, pressing a laminate of the absorber 22 and the top sheet 21 (hereinafter, also referred to as an “absorbent portion”). Provided. This squeezing is performed, for example, by embossing rolls. As a result, the top sheet 21 and the absorber 22 are occluded and integrally joined in the entire recess 25 extending from the bottom surface (bottom wall) to the wall surface (side wall) of the recess 25. The thickness of the top sheet 21 and the absorber 22 at the bottom of the recess 25 (thickness of the absorbent portion) is preferably about 1/2 to 1/7 of the thickness of the absorber 22 at the non-squeezed portion. More preferably, it is about 1/4 to 1/7. With this configuration, the top sheet 21 and the absorber 22 are integrally formed, so that the top sheet 21 and the absorber 22 are firmly joined to each other, the top sheet 21 is hard to peel off, and the absorber 22 swells after urination. , The top sheet 21 is in a state along the groove, and the groove is maintained. In the present invention, of course, a form in which the absorber 22 is not provided with the recess 25 is also allowed.

<Side seal part>
5A and 5B are diagrams showing an example of an adhesive pattern of the side seal portion, FIG. 5A is an adhesive pattern of only characters, FIG. 5B is an adhesive pattern in which characters and a rectangle are combined, and FIG. 5C is. Represents the adhesive pattern formed on the continuum of diapers before cutting for each absorbent article.

In the present embodiment, as described above, the pair of side seal portions 19 of the diaper 10 have predetermined characters, figures, and the like drawn by the pattern forming element 19F composed of the adhesive portion 19a and the non-adhesive portion 19b. An adhesive pattern (hereinafter, also referred to as “predetermined pattern”) 19P is formed. Further, as shown in FIG. 5A, the side seal portion 19 is provided with an enclosed portion 19E surrounded by the pattern forming element 19F. As shown in FIG. 5A, the non-adhesive portion 19b of the pattern forming element 19F is arranged so as to open the surrounded portion 19E.

The predetermined pattern 19P can be a character, a figure, a symbol, a pattern, or a combination thereof. In the present embodiment, the predetermined pattern 19P is an arrangement of the alphabetic characters “O”, “A”, and “B” as shown in FIG. 5 (a). In the present invention, the predetermined pattern 19P is "Grid Press" so as to suggest that the absorber 22 is provided with the recesses 25 in a grid pattern, for example, as in the diaper 10 according to the present embodiment. Etc. may be characters. Of course, a figure such as a heart shape or a star shape may be adopted as the predetermined pattern 19P.

The pattern forming element 19F is a linear one having a width, and in the present embodiment, a predetermined pattern 19P is formed so as to have at least one surrounding portion surrounding the enclosed surrounding portion 19E. The surrounding portion 19E is formed so as to correspond to the surrounding portion. The adhesive portion 19a is a welded portion formed by ultrasonically welding the side seal portion 19. The non-adhesive portion 19b is a portion that is not ultrasonically welded, and is arranged so as to provide a notch portion in the surrounding portion as shown in FIG. 5 (a). That is, the non-adhesive portion 19b is arranged so as to open the surrounding portion 19E of the character drawn by the pattern forming element 19F. Due to this arrangement of the non-adhesive portion 19b, during ultrasonic welding, the sheet fibers in the enclosed portion 19E communicate with each other from the enclosed portion 19E through the non-adhesive portion 19b to the outside, and as a result, the enclosed portion 19E The inner sheet fibers are suppressed from being trapped, and the tension applied to the sheet constituting the enclosed portion 19E is relaxed. That is, a margin is created in the sheet fiber in the surrounded portion 19E, and excessive tension is not applied. Therefore, since the welding of the sheet fibers in the enclosed portion 19E is reduced, it is possible to prevent the characters from being crushed and becoming difficult to see. Further, by relaxing the tension, it is possible to suppress the generation of powder from the fibers constituting the sheet of the surrounded portion 19E. In the present embodiment, the predetermined pattern 19P is formed on each of the pair of side seal portions 19, but in the present invention, it may be formed on at least one of the pair of side seal portions 19.

Ultrasonic welding is performed in a state where the semi-finished product is flowing on a conveyor or the like, and when the ultrasonic vibrator is pressed, a strong tension tends to be generated in the flow direction of the manufacturing process of the diaper 10. Therefore, from the viewpoint of relaxing the strong tension, the non-adhesive portion 19b is arranged near the upstream and / or downstream ends of the diaper 10 in the manufacturing process flow direction in the surrounding portion of the predetermined pattern 19P. Is preferable.

In the present embodiment, as shown in FIG. 5A, the “O” of the predetermined pattern 19P is notched on the left and right, that is, the non-adhesive portion 19b is provided. Further, in the "A" of the predetermined pattern 19P, non-adhesive portions 19b are provided on the left and right so that the enclosed portion 19E of the "A" is opened. Further, in the "B" of the predetermined pattern 19P, non-adhesive portions 19b are provided on the left and right sides so that the two enclosed portions 19E of the "B" are opened respectively.

In FIG. 5A, a represents the line width of the pattern forming element 19F, b represents the height of the predetermined pattern 19P, and c represents the width of the side seal portion 19. In this embodiment, a is 0.4 mm, b is 4 mm, and c is 10 mm.

FIG. 5B is another embodiment of the present invention, but in addition to the predetermined pattern 19P, a rectangular adhesive pattern P2 may be arranged on the side seal portion 19 as shown in the drawing. As in this configuration, the adhesive pattern 19P having the enclosed portion 19E and the non-adhesive portion 19b and the adhesive pattern P2 having no non-adhesive portion 19b may be combined. With this configuration, the adhesive strength of the side seal portion 19 can be freely set.

The continuum of the diaper 10 shown in FIG. 5 (c) is obtained at the final stage of the manufacturing process of the diaper 10, and from the state shown in FIG. 5 (c), the continuum of the diaper 10 is drawn with lines X and lines. By cutting along Y, one diaper 10 having a side seal portion 19 having an adhesive pattern as shown in FIG. 5B on one side can be obtained.

Conventionally, in a pants-type disposable diaper in which a pair of left and right side seal portions are formed on the left and right side edges of the exterior body, the adhesive portion of the side seal portions is, for example, a portion in which sheets constituting the exterior body are overlapped. Patent Document 1 discloses a disposable diaper formed by welding by ultrasonic vibration and provided with an adhesive pattern of letters, symbols, and logo marks in order to impart an identification and advertising effect to the side seal portion.

However, in the disposable diaper described in Patent Document 1, when an adhesive pattern is formed by ultrasonic vibration, the fibers constituting the sheet lose a place to escape in the portion surrounded by the forming element of the adhesive pattern, and the density of the fibers becomes high. Since the height is high, high-speed vibration may be applied to the enclosed portion, and heat due to friction may be generated. Therefore, the vicinity of the outline of the enclosed portion is welded, the area of the enclosed portion becomes small, the appearance is crushed, and it becomes difficult to recognize the characters of the adhesive pattern, resulting in identification and advertising effects. There was a risk that it could not be fully exerted.

Further, as a result of the enclosed portion, that is, the portion where the fiber becomes dense and hardened, comes into contact with the ultrasonic vibrator, the fiber is torn into small pieces to generate powder, and the powder is ultrasonically welded. Could be a hindrance to.

According to the present embodiment, as described above, when the adhesive pattern is formed on the side seal portion, an escape route for the fibers constituting the sheet is formed in the portion surrounded by the forming element of the adhesive pattern. The density will decrease and the generation of heat due to friction will be suppressed. As a result, the vicinity of the contour of the enclosed portion is not welded and the contour of the adhesive pattern becomes clear, so that the adhesive pattern can be easily recognized, and as a result, the display, identification, and advertising effects can be effectively exhibited. ..

Further, since the fiber density of the enclosed portion is lowered, the enclosed portion is softened, and the powder generated when the ultrasonic vibrator comes into contact with the enclosed portion can be reduced, resulting in ultrasonic waves. It is possible to improve the accuracy of welding.

The predetermined pattern 19P capable of effectively exerting the above-mentioned effect of the present invention is not limited to the above-described embodiment, and well-known characters, figures, symbols, patterns, or combinations thereof may be adopted.
