Waist Opening Patents (Class 604/385.3)
  • Patent number: 8574212
    Abstract: An absorptive article has an absorptive article body, a pair of side flaps, and a pair of waist flaps provided in the rear region so as to extend outward from the side flaps in the lateral direction of the absorptive article body. Each of the pair of waist flaps has formed thereon a waist stretchable region extended so as to reach that edge of the waist flap which is on the belly side. The waist stretchable regions are adapted such that the dimension of the waist stretchable region stretched at the end thereof on the belly side in the lateral direction of the absorptive article body is greater than the dimension of the waist stretchable region stretched at the end thereof on the rear side in the lateral direction of the absorptive article body.

  • Patent number: 8568552
    Abstract: In an outer covering sheet of an absorbent product, first, second and third adhesive layer elements each extending in a left-right direction are formed on a second covering sheet by spiral spray application. Each of these adhesive layer elements has wide width parts and narrow width parts which are continuous with the wide width parts, respectively. Therefore, hot melt adhesive can be stably discharged across the entire length of the adhesive layer element, unlike in the case where only wide width parts are formed intermittently. As a result, it is possible to obtain the outer covering sheet which is a sheet member having the adhesive layer elements with desired shapes where unevenness is decreased. In the absorbent product which is manufactured with use of the sheet member, the comfort level of the wearer can be prevented from decreasing due to unevenness of thickness of the adhesive layer elements.

  • Patent number: 8529536
    Abstract: A method of making an elastic composite entails conveying a first sheet on a conveyor, and wrapping a section of elastic about the first sheet and the conveyor, thereby applying elastics cross directionally across the sheet. A second sheet is then applied onto the first sheet thereby creating a subcomposite including the two sheets and elastics sandwiched therebetween, wherein two elastics extend outward from one side of the subcomposite, about the conveyor, and return into an opposite side of the subcomposite. The subcomposite is cut through the first and second sheets and the elastics, thereby separating the subcomposite into a first carrier and a second carrier, each carrier including a material layer, whereby spaced apart elastics extend from the first carrier to the second carrier, the first and second carriers defining an exposed elastic region therebetween formed by the elastics.

    Abstract: A disposable diaper has an absorbent body, an outer covering sheet and two end holding sheets, and both end portions of the absorbent body are fixed between the end holding sheets and the outer covering sheet. Since a turndown portion of an upper end portion of the end holding sheet is bonded on an upper end portion of a first covering sheet, a waist covering portion has structure where the first covering sheet is laminated on the two-layered end holding sheet. Therefore, a thickness of the outer covering sheet can be reduced, while maintaining strength of the waist covering portion by appropriately selecting material of the end holding sheet, thereby to easily improve softness of the disposable diaper. Since an upper end of a second covering sheet is positioned below the turndown portion, softness and breathability in an area between the turndown portion and the second covering sheet is increased.

The first edge zone and the second edge zone are separated by a middle zone. The middle zone, which has the same length as each edge zone, is stretchable, but to a lesser extent than the edge zones. Through this construction, the absorbent article exhibits improved fit and appearance. Of particular advantage, the carefully controlled stretch properties prevent sagging or drooping of the crotch region, even after the crotch region has been wetted.

  • Patent number: 8377021
    Abstract: Winkles are prevented from being generated in the flap portion to reduce an uncomfortable feeling and friction. In a sanitary napkin including an absorber interposed between a liquid-permeable top sheet and a liquid-impermeable back sheet and a flap portion surrounding the absorber without including the absorber, the flap portions at least in a front area and a back area of the sanitary napkin each have an outer shape of a wave-like line composed of convex curves and concave curves in which the direction of a line tangent to the outline of the flap portion is continuously changed; the width of the absorber gradually narrows in each of the front side area and the back side area in such a manner that lines incline toward each other to form a convex curve; and the wave-like line is formed along each of the inclining lines.

  • Patent number: 8377027
    Abstract: Absorbent articles having form fitting properties are disclosed. In particular, the absorbent articles include at least one waist elastic member that extends a substantial distance in the longitudinal direction. The waist elastic member, for instance, may be positioned in a front region of the article, in a back region of the article or in both the front and back regions. The waist elastic member includes a breathable elastic film. In order for the film to be breathable, the film includes apertures. The apertures appear on the film according to a particular pattern and having a particular diameter so that the film retains desired stretch properties.

    Abstract: A disposable wearing article improved so that the crotch panel may be stably fastened to the outer surface of the waist panel and a relatively large amount of body waste may be absorbed and retained without deteriorating the absorption performance of the liquid-absorbent structure in the crotch panel. One of front and rear end portions of a crotch panel is attached to respective non-skin-facing sides of elasticized waist panels by the intermediary of bond-regions respectively including non-bond regions in midsections thereof. The waist region to which the one end portion is attached is formed at the midsection thereof with a separable portion extending in a longitudinal direction when a wearing article is put on the wearer's body.

    Abstract: A garment comprises a laminate. The laminate comprises a first layer colored a first color, and a second layer colored a second color different than the first color. The laminate includes a folded flap in the waist region, thereby defining an integral, outwardly visible waistband having a waistband lower edge. In one embodiment, the first layer and the second layer are coterminous at the waistband lower edge. In particular embodiments, the folded flap is an outwardly folded flap, and the first layer is an inner layer and the second layer is an outer layer, and the outwardly visible waistband is colored the first color. The distinction between the first color and second color in conjunction with the fold creates a visible waistband effect.
