[Problems to be solved by the device]

 Since the above-mentioned disposable diaper is only worn locally, it is extremely excellent in that it does not cause blood circulation disorders, rashes, inflammation, etc. when worn, and it also prevents side leakage. When water such as urine is absorbed from the groove in the middle of the second bent portion, if the water is large, the absorption by the water absorbing layer may not catch up and the paper diaper may leak.

The paper diaper of the present invention is intended to solve the above-mentioned drawbacks of the conventional example, and when the amount of water such as urine is large, the paper diaper does not leak from the paper diaper even if absorption by the water absorption layer cannot catch up with The purpose of the present invention is to provide a disposable diaper that can be surely absorbed by the water absorbing layer.

[0007]

[Means for Solving the Problems]

 The paper diaper of this invention has a waterproof layer on one side of the water-absorbent layer and a water-resistant water-permeable layer on the other side. It is butt-joined, and the above end is sealed to form a bag, leaving one end in the lengthwise direction, and this is folded back into a tubular shape from the open end to cover the surface of the waterproof layer. It is what

[0008]

[Action]

 According to the disposable diaper of the present invention, since it is worn only on the user's local area, there is no blood circulation disorder, rash, inflammation, etc. at the time of wearing, and side leakage can be prevented.

In addition, even if the water absorption layer does not catch up with a large amount of water such as urine, it does not leak from the diaper and can be reliably absorbed by the water absorption layer.

[0010]

【Example】

 An embodiment of the disposable diaper of the present invention will be described below with reference to the drawings.

1 to 5 illustrate one embodiment of the disposable diaper according to the present invention.

In FIGS. 1 and 2, reference numeral 1 denotes a sheet main body that constitutes a paper diaper, and a water-absorbing layer 2 cut on a predetermined length has a waterproof layer 3 on one side and a water-resistant water-permeable layer 4 on the other side. It was provided.

The water-absorbent layer 2 is formed by polymerizing a plurality of thin water-absorbent sheet materials, cotton-like crushed pulp, water-absorbent polymer, or the like, and has a relatively thicker wall thickness than the other materials described above. It can quickly absorb excrement such as urine.

The waterproof layer 3 is a thin sheet material obtained by laminating a synthetic resin film such as polyethylene on one side of waterproof paper, plain paper, rayon paper or the like, or a synthetic resin such as polyethylene is formed into a thin film as it is. Of these, those having a sufficient waterproof effect even when contacted with urine or the like absorbed in the water absorbing layer 2 can be suitably used.

Further, the water-resistant water-permeable layer 4 is made of a non-woven fabric using rayon, polypropylene fiber or the like, allows urine to pass through between the fibers, and has sufficient strength even when wet.

The water-absorbent layer 2 has a sheet-shaped body 1 formed by fixing the ends of the waterproof layer 3 and the water-resistant water-permeable layer 4 arranged on both sides thereof and stacking them together in a sandwich. The sheet-shaped main body 1 can be appropriately molded as one body.

3 to 5 show a process of forming the sheet-shaped main body 1 to manufacture the paper diaper of the present invention. First, as shown in FIG. Bend along the direction to the water resistant water-permeable layer 4 side and abut.

Next, the abutting portion and the end portion in the length direction of the sheet-like main body 1 are heat-sealed with one end in the length direction left as shown in FIG. 4, or a synthetic resin forming the waterproof layer 3. The film is sealed by a means such as bonding with an adhesive capable of bonding the film to form a bag. The length of the sealing portion 5 at the abutting portion can be appropriately determined in consideration of the ease of mounting on the local portion, whether leakage can be reliably prevented, and the age of the user. A local area of the user is fitted into the opening formed at this time.

Finally, as shown in FIG. 5, the sheet-shaped main body 1 is folded back in a cylindrical shape from the open end side toward the outside onto the surface of the waterproof layer 3 so as to almost cover the surface of the waterproof layer 3. A paper diaper consisting of an inner cylinder and an outer cylinder is completed.

In the figure, 6 is an adhesive layer attached to the end of the sheet-shaped main body 1 on the inner cylinder side, and a release sheet 7 is attached to the front surface. When the adhesive layer 6 is used, the release sheet 7 may be peeled off and the adhesive layer 6 may be adhered to the upper part of the local area or the like.

Numeral 8 is a notch provided at the base of the opening portion into which the local portion on the outer cylinder side is fitted. If the notch 8 is opened and attached to the local portion, the feel at the time of wearing is very good. In that case, the adhesive layer 6 may be provided on both sides in the width direction instead of the end portion on the outer cylinder side (dotted line portion in FIG. 5).

The paper diaper of the present invention is configured as described above, and functions to absorb water such as urine in the water absorbing layer 2. However, the water absorbing layer 2 is formed in a tubular shape, and the waterproof layer is also formed. Since 3 covers the water-resistant water-permeable layer 4 and the water-absorbing layer 2, the water is reliably captured by the water-absorbing layer 2 and does not leak from the water-absorbing layer 2 or the like.

[0023]

[Effect of device]

 According to the disposable diaper of the present invention, since it is worn only on the user's local area, there is no blood circulation disorder, rash, inflammation, etc. at the time of wearing, and side leakage can be prevented.

Further, even if the water absorption layer does not catch up with the large amount of water such as urine, it does not leak from the paper diaper and can be reliably absorbed by the water absorption layer.
