Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diaper and a diaper set, and more particularly to a diaper and a diaper set which can be repeatedly reused after being used in a hospital / facility or the like (or at home).

[0002]

2. Description of the Related Art A diaper is used by a wide range of users from infants to adults who need care, and it is desirable that the diaper has a comfortable wearing feeling. On the other hand, it is desirable for caregivers to be able to process excrement as easily as possible without getting their clothes or hands dirty.

A diaper using a cloth such as bleaching cloth, which has been used for a long time, is usually formed by stacking several pieces of cloth and bending them. However, when using such a cloth diaper, not only is there a drawback that the excrement causes side leakage, or the permissible water retention range of the excrement is narrow, and each time it is washed for reuse, There has been a problem that manual work such as stacking or folding cloth after washing is indispensable.

Then, so-called disposable diapers became popular,
Since disposable diapers are discarded after use, it is becoming more and more popular in recent years that they are not preferable from the viewpoint of environmental protection and resource saving.

Therefore, a diaper that can be washed and repeatedly reused instead of a disposable paper diaper has been demanded, and various diapers having higher functions than conventional cloth diapers have been proposed.

As diapers that can be washed and repeatedly reused, there are mainly pad-type and flat-type diapers, and diaper covers each having a waterproof property are worn from above and used. Further, depending on the condition of the wearer, the pad type may be overlaid with the flat type, and the diaper cover may be worn over the flat type.

The pad type diaper has an exterior body which is waterproof or water repellent and has dam portions provided on both left and right sides to prevent lateral leakage of urine or the like by closely contacting the inner surface of the leg of the lower abdomen in a curved state. In general, it has a water-absorbing property and an insole body installed in the exterior body. For example, the technology disclosed in Japanese Patent Application Laid-Open No. 2001-187078 (however, the insole body is discarded) and utility model registration No. 3034065 are known.

The flat type diaper generally has a substantially rectangular flat type sheet-like structure containing a highly water-absorbent resin or the like, and can be applied according to various symptoms and physiques. For example, JP-A-11-14689
The technique disclosed in No. 3 and the like is known (however, the diaper part sprayed with the superabsorbent polymer is treated separately).
Incidentally, the flat type diaper may be used together with the pad type diaper, that is, the pad type may be superposed on the inside of the flat type diaper and used together with the diaper cover.

Such repeated reuse of diapers is generally carried out by a batch-type washing machine in hospitals and facilities. Further, in the linen industry, a continuous washing machine (continuous washing machine) or a batch type washing machine is generally used. The basic structure of the continuous washing machine is that the washers separated into multiple layers (often about 8 to 14 layers) are connected,
The structure is such that a fixed amount (in most cases, about 50 to 70 kg) of the object to be washed is sequentially sent in each step. It is largely divided into a pre-wash zone, a main wash zone, a rinse zone, and a finishing (neutralization, softening, and gluing) zone, and finally it is dehydrated by a press machine. Water is made to flow in the direction opposite to the direction in which the material to be washed advances so that dirt does not flow into the next process. The treatment conditions are set according to the type of items to be washed, and hospital linen is specially managed from the viewpoint of hygiene.

As described above, it is necessary that washing in linen companies, hospitals, facilities, etc. be performed in a complete state in terms of excrement removal, stain removal, sterilization / disinfection, drying, etc., as compared with washing in general households. Therefore, the components of the diaper are separated before being put in.

According to the aforementioned Japanese Patent Laid-Open No. 2001-187078, a pad type diaper consisting of an insole body and an exterior body is disposed of after discarding the insole body which is a disposable portion and washing only the other portion. A manual operation is performed in which a new insole body is prepared, and both front and rear ends thereof are inserted into locking portions provided at both front and rear end portions of the exterior body in a sandwiched state. In order to save manual work after washing, a structure is used that secures the entire circumference of the insole to the exterior body so that the exterior body and the insole do not separate during washing. The fixing is made by durable sewing so that it can endure the washing machine performed in the linen company, hospital, facility, etc. described above. However, there is a fear that liquid leakage may occur from the sewn portion, so that it is necessary to use a water-absorbing thread (see Utility Model Registration No. 2603090).

However, when the insole body is sewn and fixed to the exterior body around the entire circumference of the insole body using a water-absorbent thread, separation during washing can be reliably prevented, and manual work after washing is unnecessary. However, according to the research conducted by the present inventor, it was found that a problem easily occurs in terms of cleaning effect.

That is, the adverse effect that the waterproofness or water repellency of the exterior body, which has the effect of preventing the excrement of excrement from leaking to the outside when worn, acts as a protective wall against the washing action during washing and hinders washing. This is because For this reason, it has been found that the excrement absorbed into the insole body and the excrement that has entered the insole body rear surface side, which is the exterior body side, are difficult to be removed by the waterproofness or water repellency of the exterior body.

Therefore, in order to completely remove the excrement that has penetrated deeply into the insole to the side of the exterior body, the method described in the above-mentioned Japanese Patent Laid-Open No.
Applying the technology of 001-187078, it is possible to remove the reusable insole from the exterior body, wash it, and attach it to the exterior body at the time of use, but this attachment operation is done manually. Inevitably, the cost will increase.

[0015]

Therefore, an object of the present invention is that, regardless of whether it is used for commercial or domestic laundry, the cleaning effect at the time of washing is high and hygienic simply by putting it in, and the drying time is greatly shortened. Moreover, it is another object of the present invention to provide a diaper and a diaper set which do not require manual work as in the past after washing.

[0016]

The above-mentioned objects of the present invention can be achieved by the following constitutions.

1. An exterior body having waterproofness or water repellency and having dam portions provided on both left and right sides to prevent lateral leakage of urine and the like by closely contacting the inner surface of the leg of the lower abdomen in a curved state,
