In addition, disposable diapers are generally divided into insert type and panty type, and the panty type diaper is kept in the overlapped form when the waist flap is worn, preferably the rear flap of the waist portion. Fastening tapes as detailed in Korean Patent Publication No. 95-703315, snap buttons as detailed in Korean Patent Application No. 87-9747, hooks as detailed in Korean Patent Application No. 89-199, and the like. It is attached to the back flap of the waist, and overlaps with the front flap and is fixed to the body part including the groin, hip, and belly of the body so that it can be worn. The insert diaper does not have the flap. Separate aids for wearing on the body, such as the use of a separate waistband or diaper cover Say the necessary diapers.

The diaper cover is worn while holding the insertable diaper in the diaper cover, so the diaper cover and the elasticity of the diaper are better than the waistband that fits the front and rear portions of the insertable diaper between the waist and the body. It is widely used without a red mark due to the stimulus of.

In addition, the diaper cover does not have an absorbent body, and preferably, after attaching the insertable diaper to the diaper cover, the flap of the rear waist portion is extended to cover and overlap the waist at the front part of the wearer, that is, the abdomen when worn.

Determination of wearing convenience

Disposable disposable diapers and diapers cover manufactured in the above Examples and Comparative Examples are divided into three parts according to the weight of the baby, divided into five products each for 100 small size, 100 medium size, and 100 large sized products, and a perfect score of 10 points. Satisfaction was scored by absolute score and averaged.

Judgment result of wearing convenience

10-point scale

According to the determination result, children who wear a medium size rather than a small size, and babies who wear a large size rather than a medium size show a great satisfaction in the convenience of wearing. Most of the children who fill small are less comfortable to wear diapers to the wearer because they are lying down and less active, whereas the medium-sized babies are more active, such as flipping over and sleeping, and sometimes holding, and do not have fixed movements. It is inconvenient to use diaper cover, and it is more inconvenient to wear because the large babies are standing around and very active, so the diaper cab and the insert diaper are placed on the floor in the posture and posture of the babies of medium and large size. It can be seen that Examples 1 to 6, in which the diaper cover and the insert-type diaper are fixed by the tab when the vertical filling operation is performed, are easier to compare with Comparative Example 1.

In Comparative Example 2, the double-sided tape may be applied to the center portion of the back sheet of the diaper to prevent separation of the diaper and the diaper cover. However, the ends of the waist of the diaper as in Examples 1 to 6 are not fixed. Therefore, it is very inconvenient to stand or fill in the posture.

In Example 4 to Example 6, the mechanical fastening system of the hook was applied to the lower part of the protruding tab outer portion as in Examples 1 to 3, but the satisfaction was slightly increased. It was not at the level, the effect was greater when two tabs than Example 1 and Example 2 and Example 4 and Example 5 than when one tab, Example 2, Example 3 and Example 5 In comparison with Example 6, when the tab is three, the operation of spreading the tab increases, rather than wearing two tabs, rather than two.

Therefore, the present invention provides a fastening means to facilitate wearing even in the posture and standing posture of the wearer by fixing the diaper cover and the insertable diaper through two tab fastening structures inherent in the insertable diaper. .
