  Folding structure of disposable underpants and disposable underpantsUSPTO Application #: 20060218700Title: Folding structure of disposable underpants and disposable underpants Abstract: There is provided a folding structure of disposable pants which includes an outer wear sheet of pants shape and an absorbent main body adhered to a skin-contacting surface side in the outer wear sheet, wherein elastic members are added at least to circumferences of a waist opening and a leg opening. The structure is formed by folding back a crotch part 5 of the disposable pants over a center pants part 7 on the upside of the crotch part, folding back a left lateral part 8 and a right lateral part 6 of the pants over the center pants part 7, respectively, and then folding back an upper pants part 9 in which the left and the right lateral parts of the pants are overlapped with each other, over a downside part 10 thereof.

TECHNICAL FIELD [0001] The present invention relates to folding structures of disposable pants which are preformed into a pants shape, and more particularly, to folding structures of disposable pants which are suited for large adult-sized pants. BACKGROUND ART [0002] FIG. 8 is a front view of conventional disposable pants. In these disposable pants, to an outer wear sheet 50 formed into a pants shape by providing an waist opening W and leg openings S, S, there are added an waist elastic member 51, a leg elastic member 52, and a body fitting elastic member 53, and an absorbent main body 54 is adhered to a skin-contacting surface side. Longitudinal ends of the absorbent main body 54 contract toward the center of the pants through contraction force of the body fitting elastic member 53. In the right and left lateral side parts of the pants where the absorbent main body is not disposed, contraction force of the body fitting elastic member 53 gives gathers and provides fluffy condition. [0003] The absorbent main body 54 of the conventional disposable pants has a structure where a water-absorbent core formed of pulp fiber and super absorbent polymer powder is disposed between a water-impermeable film and a water-permeable nonwoven fabric. Due to the existence of the pulp fiber, it is formed so as to have rough and thick appearance. [0004] In order to improve the portability in bringing back, the disposable pants are desirably packed in a compact package, and therefore, the disposable pants should be folded. Because of the bulky absorbent main body 54 and deformation through contraction force of the body fitting elastic member 53, the above conventional disposable pants are folded in such a manner that right and left lateral parts of the pants are folded back over the center part of the pants along folding lines L1 and L2 shown in FIG. 8 to give a shape as shown in FIG. 9, and then an upper part of a folding line L3 is folded back over a lower part to give a trapezoidal shape as shown in FIG. 10(a). [0005] As seen from the schematic side view of the folded pants in FIG. 10(b), the bulky absorbent main body 54 is folded in four, so that a large difference in thickness arises between the lower part where the absorbent main body 54 is folded and the upper part where only the outer wear sheet 50 is present. In the case of a folding structure having parts with different thicknesses, the disposable pants of such a folding structure are inferior in handling ability when put in a package, leading the problems that good packaging is impossible and each package is not well self-organized. [0006] In addition, in the case of adult disposable pants, when the above folding structure is employed, the thickness will be 6 to 8 cm and the width and the length will be as large as about 20 cm even in a folded state. Therefore, when a user desires to carry it when going out, the bulky profile is quite unfavorable. [0007] In consideration of the above problems, it is an object of the present invention to provide a folding structure of disposable pants capable of folding disposable pants in a compact and non-bulky manner which is suited for a user to carry. DISCLOSURE OF THE INVENTION [0008] The subject matter of the present invention is a folding structure of disposable pants which comprises an outer wear sheet of pants shape and an absorbent main body adhered to a skin-contacting surface side in the outer wear sheet, in which elastic members are added at least to circumferences of an waist opening and a leg opening, and the structure is formed by folding back a crotch part of the disposable pants over a center pants part on the upside of the crotch part, folding back a left lateral part and a right lateral part of the pants over the center pants part, respectively, and then folding back an upper pants part in which the left and the right lateral parts of the pants are overlapped with each other, over a downside part thereof. [0009] By employing the above folding structure, it was possible to compactly fold disposable pants. BRIEF DESCRIPTION OF THE DRAWINGS [0010] FIG. 1(a) is a front view of disposable pants before folded, and FIG. 1(b) is a front view for explaining a first folding step. [0011] FIGS. 2(a) to 2(c) are front views for explaining second to fourth folding steps. [0012] FIG. 3 is a side view showing one exemplary folding apparatus for automatically making disposable pants into a folding structure of the present invention. [0013] FIG. 4(a) is a plan view showing a conveyance direction of disposable pants on a rotary drum, and FIG. 4(b) is a plan view showing an inverting behavior of the disposable pants on the rotary drum. [0014] FIG. 5 is a partially cutout development view of the disposable pants shown in FIG. 1. [0015] FIG. 6 is a perspective illustrative view of an ultra-slim absorbent sheet member. [0016] FIG. 7 is a sectional illustrative view of an ultra-slim absorbent sheet member. [0017] FIG. 8 is a front view of conventional disposable pants. [0018] FIG. 9 is a front view showing a folding structure of conventional disposable pants. [0019] FIG. 10 is a side views showing a folding structure of conventional disposable pants.
