  Here, the motion / posture described above is an example of the motion / posture that can be performed by the doll body 10 in the present embodiment, and is not limited thereto. Moreover, the evaluation apparatus which cannot take one operation | movement / posture among the operation | movement / posture mentioned above is not excluded from the evaluation apparatus of the absorbent article in this invention.

“2.2” Continuous Operation With the predetermined absorbent article attached to the doll body 10 in the present embodiment, the above-described operations are performed continuously or intermittently and / or the posture is continuously or intermittently performed. Thus, an evaluation approximate to the case where the absorbent article is actually mounted and evaluated for a predetermined time can be performed.

  For example, for each absorbent article, it is possible to perform a continuous motion or the like assuming a motion / attitude corresponding to the user to be used. For example, when the absorbent article is a diaper, a continuous operation or the like can be performed for each baby, infant, adult, or nursing diaper assuming an operation according to the intended user. . Further, when the absorbent article is a napkin, a continuous operation or the like assuming an operation corresponding to the user can be performed for each daytime, nighttime, and many daily napkins.

  For example, when evaluating a baby diaper, the posture can be changed by performing a continuous motion imitating the motion of a baby. For example, when evaluating a sanitary napkin, it is possible to change the posture by performing a continuous motion imitating a female motion. When evaluating an adult diaper, the posture can be changed by performing a continuous motion imitating the motion of an elderly person.

  Here, even in a diaper, since the age of the person to be used is different between the baby diaper and the infant diaper, the contents of the continuous operation and the like are also different. Further, even in sanitary napkins, the usage mode and operation at the time of wearing are different between nighttime and daytime, so the contents of the continuous operation and the like are also different. Further, even in a diaper for adults, the content of the continuous operation and the like varies depending on the age of the user to be used, the presence or absence of care, and the like. For this reason, it is preferable to make the doll main body 10 perform the corresponding | compatible continuous operation | movement etc. to the user of the absorbent article with which this doll main body 10 was mounted | worn.

  By approximating the continuous movement of the doll main body 10 in this embodiment to the movement of the user, for example, there is a possibility that a leakage state that is a specific leakage state and has a low occurrence probability may occur. In other words, there are rare occurrences in the market evaluation in which the evaluation is actually performed by wearing the apparatus on the human body, and further, it may be possible to observe a leakage state or the like where it is extremely difficult to observe the occurrence. Such a point is also one of the excellent points of the absorbent article evaluation apparatus.
