[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disposable paper diaper having a pattern or a letter (hereinafter referred to as “design”) on the outer surface of a backsheet, and more particularly to a disposable paper diaper suitable for infants.
[0002]
[Prior art]
Conventionally, the basic structure of such disposable paper diapers is that a liquid-permeable top sheet that covers the front side, that is, the side that contacts the skin, a liquid-impervious back sheet that covers the back side, and a space between these sheets. The front and back bodies are formed by folding the intervening absorber from the central portion in the longitudinal direction, and two types, tape type and pant type, are generally well known. Here, one end of the tape-type paper diaper is fastened to both side portions on the back side of the back body of the back sheet, and the other end of the fastening tape for attaching the diaper extending in the left-right direction is connected to the front body of the back sheet. The pants-type disposable diaper is attached to the side edges of the folded front body and back body together to close the pants. It is a type.
[0003]
In these disposable diapers, a disposal tape for disposal after use is fastened at one end at the center of the back body (or front body if necessary) or above, and the whole is folded in the length direction. It can be pulled out from the other end. This disposal tape is used to roll up and fasten a used paper diaper from, for example, the crotch part side, and is also called a post-processing tape.
[0004]
By the way, in the conventional disposable paper diaper mentioned above, a design comprising various patterns and characters that can be recognized from the outside at the time of wearing is constituted by a back sheet for the purpose of displaying the front and rear distinction at the time of wearing or the size etc. There are printed on the front and back body. In particular, disposable disposable diapers for infants are known to have a design composed of a pattern that is preferred or interested by infants such as animals, vehicles, or characters, for the purpose of educational purposes.
[0005]
In particular, disposable diapers having such a design applied not only to the back sheet but also to the front sheet attached to the outer surface of the front part of the abdomen of the front body have been provided on the market.
[0006]
FIGS. 9 to 11 show an example of a tape-type disposable paper diaper, which is related to the earlier application of the present applicant. That is, FIG. 9 is a perspective view showing an outline of this tape-type disposable paper diaper (hereinafter referred to as “paper diaper 1”), FIG. 10 is a plan view showing the paper diaper 1 unfolded, and FIG. 11 is a front body of the paper diaper 1. It is a front view of the front seat attached to the abdominal part position outer surface.
[0007]
As shown in FIGS. 9 and 10, the paper diaper 1 includes a liquid-permeable top sheet 2 made of a nonwoven fabric or the like covering the front side, a liquid-impermeable back sheet 3 made of a polyethylene sheet or the like covering the back side, An elastic stretchable member 5 having an absorbent body 4 made of cotton-like pulp or the like interposed between the sheets, and made of a rubber string or the like on the leg periphery adjacent to the absorbent body 4 and on the front and rear end sides of the unfolded state. As shown in a perspective view in FIG. 9, a front seat 6 is attached to the outer surface of the front body abdomen position of the back seat 3 so as to extend in the left-right direction.
[0008]
On the other hand, as shown in FIG. 10, a fastening tape 7 is provided on both sides of the back side so that one end thereof is fastened to the front side edge of the back sheet 3 with an adhesive or the like and extends to the left and right outside. ing. A hooking hook sheet 8 is provided on the inner surface of the fastening tape 7, and the hook of the hook sheet 8 engages and disengages with the hook receiver on the outer surface of the front sheet 6, so that the disposable diaper 1 can be attached to and detached from the waist of the body. It has become.
[0009]
As shown in FIG. 11, a pair of left and right locking mark patterns 9 indicating positions where the end portions of the hook seat 8 are locked are provided on the outer surface of the front seat 6. A plurality of the locking mark patterns 9 are arranged side by side in the left-right direction. In this example, the locking mark patterns 9 are composed of a numeral portion 9a, a broken line portion 9b, and the like.
[0010]
Here, each number portion 9a is given as a pattern in the order given from the center side of the front seat 6. In this example, the number portions 9a are arranged at substantially equal intervals "1", "2", " 3 ”, an Arabic numeral pattern 9a1 and a circular outer edge 9a2 surrounding the Arabic numeral. The broken line portion 9b is formed by arranging circular patterns upward in the upper part of the Arabic numeral pattern portion 9a1. Between each mark pattern 9, that is, between each pattern portion 9a1, a design composed of a pattern 10 such as an animal, a toy, or a character that an infant likes or shows interest is provided for the purpose of educational purposes.
[0011]
[Problems to be solved by the invention]
However, when the paper diaper 1 configured as described above is mounted on an infant or the like and the hook sheet 8 of the fastening tape 7 is locked to the outer surface of the front sheet 6 and fixed to the waist, as shown in FIG. Since the outer surface of the tape 7 is plain (usually white), the outer surface hides the above design (in this example, the character's face) applied to the outer surface of the front seat 6, and the original design of the folded design There was a drawback that the purpose was lost. Further, when the front sheet 6 designed by such a different color fastening tape 7 is partially covered, there is a sense of incongruity for the viewer. Furthermore, when the disposable diaper 1 is mounted, when a wearer such as a mother locks the end of the fastening tape 7, that is, the hook sheet 8 to the front sheet 6, it is mounted with little awareness of the locking mark pattern 9. In many cases, the fastening tape 7 is easily displaced from the front seat 6 and sometimes comes off depending on the user's own sense.
[0012]
The disadvantage that the design of the tape member is damaged in this way is not limited to the fastening tape in the tape-type disposable paper diaper, but also applies to the disposal tape. FIG. 13 is a perspective view of an example of a pants-type disposable paper diaper (hereinafter referred to as “paper diaper 21”) as seen from the back body side. As shown in FIG. 13, the paper diaper 21 has a liquid-impermeable back covering the back side. Design on the outer surface of the front body 23 and the back body 24 formed by the sheet 22 (in this example, various animals 25a such as “cage”, “bird”, “elephant”, etc. are drawn inside the circular pattern 25b) 25, and a waste tape 26 is fastened to the outer surface of the back sheet 22 at the substantially central portion of the back body 24. The whole is folded and bonded in the length direction so that it can be pulled out from the other end. It is installed.
[0013]
However, because the disposal tape 26 is positioned and fixed to the design part (in this example, the face part of “Penguin Bird”) applied to the outer surface 24 of the back body 24 of the back sheet 22 in this way, The paper diaper 21 has a drawback that the original purpose of the design cannot be achieved as described above. Moreover, even if it is not fixed on the designed pattern, the outermost surface 26a of the disposal tape 26 is plain and has nothing to do with the design applied to the outer surface of the backsheet 22. Because it is present or colored, there is still a sense of incongruity. For this reason (even if this disposal tape 26 is provided on the front body 23), the worn infant unconsciously uses it for disposal. There was a concern that the tip of the tape 26 would be pulled.
[0014]
The present invention has been made under the circumstances as described above, and the object thereof is not to obstruct the design applied to the outer surface of the back shishi by the tapes provided in the disposable paper diaper , particularly the disposal tape. Another object of the present invention is to provide a disposable paper diaper that does not feel strange to the eye and that can be educated for an infant who is a wearer.
[0015]
[Means for Solving the Problems]
The object of the present invention is to provide an absorbent body between a liquid-permeable top sheet that covers the front surface side and a liquid-impermeable back sheet that covers the back surface side, and fold the sheet material from the center in the longitudinal direction. A diaper-attached fastening tape formed on the back side of the back sheet and extending in the left-right direction, and a front-body abdomen position outer surface of the back sheet A front seat attached to the other end of the fastening tape and attached to the back body or the front body of the back sheet so that one end is fastened and the whole is folded in the length direction and pulled out from the other end. a disposable paper diaper comprising comprises a tape diaper disposal, the backsheet, the fastening tape, the front seat, and all outside the other end of the disposal tape Characterized in that subjected to pattern or character correlated each other, is achieved by a disposable paper diaper according to claim 1.
[0016]
