DETAILED DESCRIPTION
(21) A fully padded sleep-time disposable diaper according to embodiments of the present disclosure will now be described with reference to FIGS. 1-20. Persons of ordinary skill in the art would understand that various changes can be made to the preferred embodiments described herein without departing from the spirit of the disclosure.
(22) FIGS. 1-5 illustrate a fully padded disposal diaper 100 according to the first embodiment of the invention, which is shaped to fit a small body (not shown) just like briefs (underwear) and may be constructed of conventional materials. Diaper 100 comprises an impermeable exterior surface material 7, a permeable interior surface material 8 and an absorbent padded lining 9. Exterior surface material 7 is preferably made from a fabric that is water and fluid resistant in order to protect the toddlers' outer garments from moisture, such as for example a nonwoven or breathable polyethylene film. Interior surface material 8 is preferably made from nonwoven fabrics, such as for example GMO free wheat, corn, bamboo, cotton, pulp, or synthetic polymers, to provide a soft lining for increased comfort of the toddler wearing the diaper.
(23) Diaper 100 includes a front portion 1, a back portion 2, leg holes 3a and 3b, and a top portion 4 that includes an elastic stretch portion 5 and a seam 10, described below. The front portion 1 and the back portion 2 are formed as a single continuous body structure, just like underwear briefs, with elasticized leg openings and elasticized torso opening. Elastic stretch portion 5 allows the diaper to easily accommodate children of different sizes and girths. Leg holes 3a and 3b are defined by stretch leg portions 6a and 6b comprising one or more elastic threads sewn into the diaper. Stretch leg portions 6a and 6b allow the leg holes to stretch in order to accommodate legs of various sizes.
(24) One or more layers of absorbent padded lining 9, such as eco friendly, chlorine and fragrance free, sustainable hypoallergenic, naturally breathable liquid absorbing materials formed as usable fabrics, for example, GMO free wheat, corn, bamboo, cotton, pulp, or synthetic polymers, are situated between exterior surface material 7 and interior surface material 8 (FIG. 5).
(25) Exterior surface material 7, layers of absorbent padded lining 9, and interior surface material 8 may be affixed to one another by stitching, by a suitable adhesive, or by other conventional means known in the art. For example, stitching may be done at the torso opening and leg openings to secure an elastic material with the interior surface material 7, the absorbent lining 9, and the exterior surface material 8.
(26) As illustrated in FIG. 4, back portion 2 of diaper 100 includes a partially separable seam 10 extending downward from the torso opening. Seam 10 comprises two overlapping areas 11 and 12 which may be secured to each other by including VELCRO brand hook fasteners on overlapping area 11, and including VELCRO brand loop fasteners on overlapping area 12, or vice versa. Other conventional ways of securing overlapping areas 11 and 12 to close seam 10 may be used including non toxic adhesive at seams and joints. In a preferred embodiment, seam 10 is approximately 4 inches long as measured from point 10a at the torso opening to point 10b on the body portion. Locating seam 10 on the back side of the diaper, as opposed to locating the seam on a side of the diaper, and having a partially separable seam that reaches down a portion of the back of the diaper, as opposed to having a fully separable seam going all the way down the side of the diaper so that the diaper is fully openable along the seam, is particularly advantageous for toddler boys, because at that age, boys tend urinate up or sideways, and having no seams or fastening means on the sides ensures the greatest protection from moisture and leakage at the sides of the diaper.
(27) Interior of diaper 100 includes absorbent padded lining 9 disposed between exterior surface material 7 and interior surface material 8. FIG. 5 is a view of an enlarged portion of the disposable diaper of FIG. 1 with the interior surface material 7 partially peeled back to expose the absorbent padded lining. FIG. 5 illustrates absorbent padded lining 9 situated between exterior surface material 7 and interior surface material 8. FIG. 3, which is a laid-open view of the disposable diaper of FIG. 1 split at the sides with the interior surface material 7 removed to expose the absorbent padded lining, illustrates absorbent lining 9 in the interior of the disposable diaper according to the first embodiment of the invention. Absorbent padded lining 9 extends to the bottom edge of elastic stretch top portion 5, around the edges of seam 10, and to the interior edge of the stretch leg portions 6a and 6b. In this embodiment, absorbent padded lining 9 does not extend to the top edge of the elastic stretch portion 5 of the diaper and does not extend into the stretch leg portions 6a and 6b of the diaper.
(28) Providing absorbent padded lining 9 over the entire area of interior portion material 8, including all the way to the bottom edge of the elastic stretch top portion 5 and to the interior edges of the elastic portions 6a and 6b of leg holes 3a and 3b, is particularly advantageous for toddler boys because it provides better protection from moisture and leakage than conventional diapers with side seams or fasteners.
(29) FIGS. 6-10 illustrate a fully padded disposal diaper 200 according to the second embodiment of the invention. Diaper 200 includes a front portion 1, a back portion 2, leg holes 3a and 3b, and a top portion 4 that includes an elastic stretch portion 5 and a seam 10. One or more layers of absorbent padded lining 9, such as eco friendly, chlorine and fragrance free, sustainable hypoallergenic, naturally breathable liquid absorbing materials formed as usable fabrics, for example, GMO free wheat, corn, bamboo, cotton, pulp, or synthetic polymers, are placed between exterior surface material 7 and interior surface material 8 (FIG. 10).
(30) As illustrated in FIG. 9, back portion 2 of diaper 200 includes a partially separable seam 10 extending downward from the torso opening. Seam 10 comprises two overlapping areas 11 and 12 which may be secured to each other by including VELCRO brand hook fasteners on overlapping area 11, and including VELCRO brand loop fasteners on overlapping area 12, or vice versa.
