DETAILED DESCRIPTION OF THE INVENTION

[Industrial application field] The present invention relates to a disposable disposable diaper that uses a joining unit that joins by entanglement when joining surfaces are overlapped with each other without using an adhesive tape as a wearing unit to a wearer. [Prior Art] In a disposable diaper using a hook-and-loop fastener, so-called "Velcro Fastener" (trade name), a fastener piece having a hook-shaped or mushroom-shaped hook or a loop-shaped hook receiver is attached to both sides of the back of the diaper main body. On the other hand, a fastener piece that is engaged with the hook or the hook receiver is attached to both sides of the outer surface of the abdomen of the disposable diaper. According to such a configuration, the disposable diaper can be easily and reliably provided to the wearer.
It has the advantage that it can be repeatedly attached and detached.

[Problems to be solved by the invention]

However, when the above-mentioned disposable diaper is to be discarded after use, disadvantages appear immediately. In other words, since the waste of the wearer is usually infiltrated into the disposable diaper after use, from the necessity of hygiene or aesthetics, it is necessary to fix the disposable diaper so that the use side is wrapped inside with the waist inside and then discarded. I have. In this case, it can be seen that the above-mentioned fixing after use can be performed by the above-mentioned disposable diaper by engaging the hooks or the hook receivers on the sheet attached to the outer surface of the abdomen of the main body of the disposable diaper and both sides of the back. However, in a state where the abdominal outer surface of the disposable diaper is compactly folded inwardly for the above-mentioned disposal after use of the disposable diaper, the hook or the hook receiver on the abdominal outer surface hides the inner side, and the above-described engagement becomes impossible. . Therefore, when the paper diaper is discarded after use, complicated work such as appropriately fixing the diaper with a separate string or the like is required. Therefore, a main object of the present invention is to provide a disposable disposable diaper that can be easily and sanitarily disposed after use. [Means for Solving the Problems] The present invention for solving the above problems includes a joining means which is composed of a first sheet and a second sheet, and which is joined by entanglement when joining surfaces thereof are overlapped. Used, a disposable diaper in which the first sheet is provided on both sides of the back waist of the disposable diaper main body, and the second sheet is provided on the outer surface of the abdomen, so that the disposable diaper can be detachably attached to a wearer. The first bonding surface is formed on an inner surface of an extension part of which extends outward from the edges of the both sides, and the first bonding surface is entangled when the first bonding surface is overlapped on the outer surface of the first sheet. A second bonding surface to be bonded is formed by
Further, the first joining surface can be temporarily fixed to the inner surface of the paper diaper main body. [Operation] In the present invention, not only the inner surface of the first sheet attached to the both sides of the back diaper of the disposable diaper forms an alligator joint surface (first joint surface), but also the outer surface thereof has a first joint surface. When the joining surfaces of the above were overlapped, a second joining surface joined by entanglement was formed. As a result, when the disposable diaper is discarded after use, the abdomen is first folded inward, and then the backside of the disposable diaper is folded back there, the first sheets are overlapped with each other, and the first joint surface and the second By joining the joining surface by entanglement, the folded and compacted state can be maintained, and the disposable diaper can be sanitarily disposed of. EXAMPLES Hereinafter, the present invention will be described in more detail with reference to the drawings. 1 to 4 show specific examples of the present invention. The illustrated diaper has a liquid-permeable surface sheet 1 made of a nonwoven fabric or the like,
An absorbent body 3 made of cotton-like pulp or the like is included between a liquid-impervious back sheet 2 made of polyethylene or the like and a flap portion left and right and front and rear (up and down in FIG. 2). A so-called thread rubber 4 is provided on the outside of the side of the absorber 3.
Is interposed between the top sheet 1 and the back sheet 2 to prevent lateral leakage. Around the outer surface of the abdomen S, a second sheet 5 having a large number of loops 5a forming a joint surface protruding from a base material 5b is provided on the liquid-impermeable sheet 2 with an adhesive or by sewing. . On the other hand, on both sides of the back B, the seats 1, 2
The first sheets 6, 6 are provided so as to extend in the width direction from the first sheet. The first sheet 6 has the base of the base 6A fixed to the outer surface of the liquid-impermeable backing sheet 2 with an adhesive 7, and the base 6a is adhered to the inner surface of the base 6A. Base material
A first joint surface 6B composed of a number of hook pieces 6b is provided on 6a. The outer surface of the base 6A is provided with a second joint surface portion 6C formed of a number of loops or hooks and intertwined with the first joint surface portion 6B (see FIG. 1). Further, when not mounted, the first joining surface portion 6B is temporarily fixed to the nonwoven fabric constituting the topsheet 1 on the inner surface of the backbone. When attaching the disposable diaper to a wearer, the first sheet 6 is peeled off from the inner surface of the back which has been temporarily fixed, and is pulled out to the side and outside, and the first joining surface portion 6B is The disposable diaper is attached to the wearer's body by causing the loop to overlap with the loop 5a of the second sheet 5. Next, after using the disposable diaper, as shown in FIG.
After folding the abdomen S of the disposable diaper body inwardly and wrapping it around both sides of the back B, one of the first sheets 6
The other first sheet 6 is superimposed thereon, and the first joining surface 6B of the first sheet 6 is pressed against the second joining surface 6C of the other first sheet 6, and these are joined by entanglement. Accordingly, the disposable diaper can be sanitarily disposed without the body fluid absorbed by the absorbent body 3 leaking out. In the above-described embodiment, the terms “hook” and “hook receiver” mean that the hook is not in the shape of an inverted letter, may be in the form of a mushroom, or that the hook receiver is not in the form of a loop but is, for example, an inverted J. Any shape may be used as long as it has a shape such as a character and is entangled with the hook. The point is that any material, such as an adhesive or a pressure-sensitive adhesive, which can be removed (peeled) mechanically by removing the chemical bond and mechanically by entanglement may be used. Further, although the second joining surface portions are provided on both outer surfaces of the first sheets 6, 6, the object of the present invention can be achieved if only one of them is arranged in the order of superposition. Including. [Effects of the Invention] As described above, according to the present invention, a used diaper can be wrapped for easy and sanitary disposal.
