DETAILED DESCRIPTION OF THE INVENTION The present invention provides a
This relates to a disposable diaper cover that can be replaced once in a while.

Conventional diaper covers are generally expensive and are used repeatedly over long periods of time. However, such diaper covers that are commonly used are treated with a water repellent agent to provide a waterproof effect, but the waterproof effect gradually decreases due to repeated washing over a long period of time, and when traveling etc. Since it is very economically disadvantageous to throw away the device after use when going out, the disadvantage is that the user must carry it with him until he returns home. On the other hand, simple diaper covers made of synthetic resin film are also used, but these diaper covers not only look unsightly and feel cheap, but also have the disadvantages of not being breathable and being difficult to wear on the body. be.

The purpose of the present invention is to solve the above-mentioned drawbacks by providing a product that not only has a good appearance, but also is inexpensive, has good breathability, is easy to wear on the body, and can be easily disposed of after being used several times or for a few days. To provide a simple diaper cover that can

Further, the present invention will be described in detail based on the illustrated embodiments as follows.

In FIGS. 1 to 3, the diaper cover 10
The cover main body 11 is made of a fiber-embedded foam sheet that is breathable, waterproof, and elastic.
A hydrophobic reinforcing sheet 12 extending in a strip shape in the longitudinal direction is bonded to the central region of the main body 11 in the width direction. Recessed notches 14 on both sides of the crotch area 13 of the main body 11
By providing the crotch area 13, the front side part 15,
It is formed narrower than the back side part 16. Main body 11
Elastic members 17 are attached to both sides of the body in an extended state to extend and contract the both sides in the longitudinal direction. Pocket portions 18 are formed at both ends of the main body 11 in the longitudinal direction, with opening edges facing each other.

The fiber-embedded foam sheet, which is the material of the main body 11, may be made by, for example, using a high-speed water jet treatment method (for example, as disclosed in Japanese Patent Application Laid-Open No. 11243/1983, filed by the present applicant). method)
It is preferable to use one that is integrally implanted. In this sheet, the fibers reach the inside of the polyurethane foam from the surface, and some fibers are intertwined with each other while others are not intertwined with each other, and the elasticity inherent to the polyurethane foam is It is not damaged, the fibers do not easily come off even after being used as a diaper cover for a relatively short period of time, and it is not only breathable but also waterproof, although not completely. In order to further improve waterproofness, hydrophobic fibers are used as the implanted fibers, and/or the fiber-embedded foam sheet is coated with, for example, silicone-based, fluorine-based, paraffin-based wax, amide-based wax, or metal stone. The waterproofness of the main body 11 is preferably treated with a water repellent such as polysiloxane, dimethyl polysiloxane, hydrogen polysiloxane, epoxy-modified polysiloxane, or amino-modified polysiloxane. The measured water pressure resistance value is 3 cm or more, preferably 10 cm or more, most preferably 20 cm or more.

As the reinforcing sheet 12, a net-like or porous sheet, a spunbond nonwoven fabric, a porous or non-porous plastic film is used. The reason why the reinforcing sheet 12 is joined in this way is that since the entire body 11 has elasticity, it becomes difficult to adjust the degree of tightening when tightening the waist area of the cover 10.
This is to solve this problem. Therefore, the reinforcing sheet 1
Preferably, the material 2 is one that has less elasticity in the width direction of the main body 11 than the material of the main body 11, or one that has no elasticity.

As the stretchable elastic member 17, a tape made of the same material as the main body 11 is used, but it may also be made of rubber tape, or it may be made of rubber with an extremely small cross-sectional diameter made by arranging a plurality of pieces in parallel. It may also be made of string.

The pocket portion 18 is preferably formed by folding both longitudinal ends of the main body 11 toward the inner surface and joining the left and right edges thereof. It may also be formed by overlapping the inner surfaces of both longitudinal ends of 11 and joining the peripheral edges excluding the opposing edges.

As shown in FIGS. 1 and 4, the dorsal portion 16
One end of an adhesive fastening tape 19 similar to that attached to conventionally known disposable diapers is fixed to the outer surface of both ends of the cover 10 in order to fasten the waist circumference of the cover 10, and its free end is attached to the main body. It is temporarily attached to a release tape 20 fixed to the inner surface of 11. on the other hand,
A substantially non-stretchable reinforcing piece 21 made of plastic film or the like is attached to the outer surface of the front side 15 to which the free ends of the fastening tape 19 are to be joined. Instead of the fastening tape 19, one of the fasteners or hooks in which a fibrous group having an engaging portion at the tip protrudes from the base material is fixed, and instead of the reinforcing piece 21, the other of the fasteners or hooks is fixed. Good too.

As shown in FIGS. 5 and 6, the cover 1 of the present invention
0, inserting and holding both longitudinal ends of a disposable diaper or cloth diaper 22 mainly made of pulp into both pocket parts 18, and adhering the free end of the fastening tape 19 to the reinforcing piece 21. It is designed to be worn by people.

As mentioned above, in the cover of the present invention, the cover main body is made of a fiber-embedded foam sheet that is breathable, waterproof, and stretchable, so it not only does not get stuffy inside, but also follows body movements. It has good elasticity and texture, making it easy to exercise, and since the reinforcing sheet is joined to the central region, it is possible to eliminate the difficulty of adjusting the tightening caused by elasticity when tightening around the waist. Further, since the cover body places the diaper on the upper surface of the reinforcing sheet and inserts both ends thereof into the pocket portion, and is appropriately tightened with the stretchable elasticity, the diaper can be stably held.

Furthermore, the cover of the present invention is a disposable item that can be changed once instead of several diapers, that is, it can be used for a short period of time, so its waterproofness does not deteriorate and it is inexpensive. Because it's there, you can easily throw it away without having to take it home with you when you go out.

Thus, the cover of the present invention has excellent characteristics even though it is disposable, and therefore can be used not only for disposable diapers but also as a cover for cloth diapers, making it suitable for practical use. Extremely useful.
