sum 2 0F 2 FIG 5 BABY PANTY This application is a continuation-in-part of copending application Ser. No. 41,377, filed May 28, 1970.

This invention relates to a baby panty, and more particu larly to a waterproof panty suitable for use over either a cloth diaper or a disposable absorbent pad.

Conventional rubber pants," which are now commonly made of plastic, generally have a gathered, elasticized construction around the leg and waist portions. While this type of panty has gained widespread acceptance, it is costly to manufacture, and a more economical article would be highly desirable. Furthermore, elasticized rubber pants must be made in different sizes to accommodate babies of varying weights, and even the provision of a range of sizes does not preclude an improperly fitting garment. Thus, the degree of elasticity around the babys legs must be sufficient to prevent leakage without cutting into or binding the skin.

To obviate this problem, rubber pants comprising a single sheet of material which is snapped together in the stomach and waist regions of the baby have been introduced. While eliminating the problems of discomfort associated with elasticized pants, it will be apparent that the fluid retention properties around the leg portions are poor in such a construction.

In accordance with this invention, a panty having excellent conformability to the limbs of a baby and enhanced comfort is provided. The structure and fit of this panty is such that one size can be used for babies of widely varying weights. Furthermore, the construction of this panty is so economical that it can be provided as either a disposable or a re-usable product.

More in detail, the panty of this invention comprises a sheet of drapable, water-impervious material having top, bottom and side edges, each of said side edges having at least one tuck in the central portion of said sheet, said tucks being in substantial alignment with each other.

The structure of this panty will be better understood by reference to the following description of the invention and the accompanying drawings in which:

FIG. 1 is a plan view of the top of one form of the panty of this invention prior to expansion.

FIG. 2 is a perspective view of the article of FIG. 1 after expansion.

FIG. 3 is a plan view of the top of another embodiment of the invention prior to expansion.

FIG. 4 is a perspective view of the panty of FIG. 3 assembled as it would appear if worn by a baby.

FIG. 5 is a plan view of the top of another form of panty according to this invention.

FIG. 6 is a perspective view showing the leg encircling portion of another embodiment of this invention.

FIG. 7 is an end view of the panty of FIG. 6 assembled as it would appear if worn by a baby.

Referring to FIG. 1, there is shown a panty which comprises a generally rectangular sheet 10 of a drapable, water-impervious material, which has top and bottom edges, 12 and 14 respectively, and side edges 16 and 18. The side edges have tucks at points 20, 22, 24 and 26. As will be apparent from the drawing, tucks 20 and 24 are in alignment with tucks 22 and 26 respectively, forming an expandable area generally designated as 28. While the tucks form a box pleat in this embodiment, the term tuck" is used in the claims and specification herein to include any construction that shortens or diminishes the length of the panty to provide an expandable area. Thus the term tuck excludes gathering, which could not form an expandable portion extending transversely of the panty. The tucks are secured at areas 30, 32, 34 and 36 by any suitable fastening means such as crimping, adhesive, doublefaced pressure-sensitive adhesive tabs, stapling, combinations thereof, etc. Areas 30, 32, 34 and 36 are shown for purposes of illustration only; fastening can be achieved at other locations in the area adjacent to the side edges of the panty.

In order to use the panty illustrated in FIG. 1, one can grasp the top and bottom edges and pull in a direction parallel to the longitudinal axis of the panty, along a line offset from a line passing through the fastened portion running in the direction of pull, or hold the panty at any convenient point and tap it in the central region, thereby obtaining the article shown in FIG. 2, wherein areas 38, 40 represent flaps formed by folding the sides of the panty inwardly. Altemately, one can apply the panty illustrated in FIG. 1 directly to the baby, expanding it in the process. In an alternate embodiment of the construction shown in FIG. 1, tucks 24, 26 can be wider than 20, 22; when the edges in such a panty are folded inwardly, the area in the region of the wider tucks is narrower than the rest of the panty, providing a panty having a defined front portion.

FIG. 3 illustrates a panty comprising a sheet of drapable, water-impervious material 40 having top and bottom edges 42 and 44 respectively, and side edges 46 and 48. In this embodiment the tucks are in the form of edge pleats 50 and 52; they are retained by heat sealing to the adjacent sheet in areas 54, 56, 58 and 60. The side edges are trimmed to define an arcuate configuration thereby fonning a central area 62 of reduced width. This panty is prepared for use in the same manner as described for that of FIG. 1; in FIG. 4, it is shown as it would appear if worn by a baby.

FIG. 5 depicts another form of the panty of this invention comprising a sheet of drapable, water-impervious material 70 having a top edge 72, a bottom edge 74 and side edges 76 and 78. Only a single edge pleat 80 is defined by the tucks in this embodiment; the tucks are retained by means of heat sealing at areas 82 and 84. The expandable area in this panty is the edge pleat.

In FIG. 6, a panty comprising a sheet of drapable, water-impervious material and having top and bottom edges 92 and 94 respectively, and a side edge 96 is shown. In this structure, the tucks form two box pleats at 98 and 100; the tucks are retained by heat sealing at areas 102 and 104. FIG. 7 illustrates an end view of the assembled panty of FIG. 6 as it would appear if worn by a baby.

Any drapable, water-impervious material may be employed in constructing the panty of this invention. Preferably, a thermoplastic material such as polypropylene film, polyethylene film, ethylene-acrylate copolymer film, ethylene-propylene copolymer film, vinyl chloride polymer and copolymer films, etc., are employed. In the preferred embodiment of this invention, 1 to 2 mil sheet of polyethylene is employed.

While panties of various dimensions can be constructed, a panty approximately 13 inches wide by 17 inches long will be suitable for most babies.

The panty is applied over, or in combination with a gauze diaper or a disposable, absorbent pad. It is secured by any conventional means, such as safety pins, double-faced pressuresensitive adhesive tapes, etc.

The panty of this invention is highly advantageous in that it presents an economical means of effectively preventing leakage around the legs of the baby. Thus, the tucks provide a cusping effect, insuring a snug, yet comfortable fit.

What is claimed is:

1. A panty comprising a sheet of drapable, water-impervious material having top, bottom and side edges, each of said side edges having at least one tuck in the central portion of said sheet, said tucks being in substantial alignment with each other and being retained so as to provide an expandable area extending transversely of said sheet.

2. The panty as claimed in claim 1 wherein said sheet is a drapable, water-impervious thermoplastic material and said tucks are retained by means of heat sealing.

3. The panty as claimed in claim 2 wherein said tucks form a box pleat.

4. The panty as claimed in claim 2 wherein said sheet has arcuate side edges defining an area of reduced width in the central portion thereof.
