Unite States Patent INFANTS DIAPER Fred F. Dexter, Houston, Tex.

Application July 26, 1954, Serial No. 445,680

4 Claims. (Cl. 128--284) This invention relates to new and useful improvements in baby diapers.

=`Previlous diapers have failed to provide sufficient absorbency without sacricing ease of laundering and/or length of service to a growing infant. Such diapers, when applied frequently cover or bind the babys stomach to spread harmful moisture to innocent areas and cause harmful pressures which may hinder digestion and even retard the healthy development of the child. `Such diapers additionally may bind or bow the babys legs preventing complete comfort and freedom of movement, or may fit the rectal area so closely as to make babys bowel movements difficult. If applied in such a manner as to be loose tting, however, such diapers are not reliable in trapping the bowel waste.

It is, therefore, an object of my invention to provide a diaper that is flexible in use and which may be expanded to grow with the baby.

lt is a further object to provide a diaper that is adaptable to the babys body contour so as to permit greater freedom of leg movement and to obviate any covering or binding of the babys stomach.

It is a further object of this invention to provide a diaper having a natural pocket in the rectal area to permit free bowel move-ment and to receive waste.

lt is a further object of my invention to provide a diaper which presents extra thicknesses of material for additional absorbency when applied to the baby without bulk enough to bow the babys legs, and which may be washed and dried quickly and easily.

It is a further object of my invention to provide an infants diaper which is simple in construction, reliable in use, `and which can be manufactured economically.

With these objects in mind I have shown and described for purposes of illustration, several embodiments of my invention, all of which are part of my generic inr ventive concept.

In carrying out my invention l utilize a conventional diaper, which may be square, rectangular, triangular, trapezoidal or of irregular contour. The central portions of the side edges are folded over in wallet fashion and preferably are releasably secured by fastening means positioned along the side edges of the diaper. The back and abdomen :covering `end portions are then unfolded to full width so that the diaper as applied assumes the ygeneral outline of an airplane, with the wings covering the babys back, the tail section covering the babys lower abdomen and the fuselage of lextra thickness extending between the babys legs. The inwardly folded side edges present a loose-fitting receptacle or pocket near the rectal area for the reception of Waste. The pocket further serves as a receptacle for a pad formed, for example, by folding a second diaper, thus providing adequate absorbency for night diapering.

The features of my invention which yI believe to be novel are set forth with particularity in the appended Iclaims. My invention itself, however, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings, in which Fig. 1 is a plan view of an unfolded, tted, contour type diaper; Fig. 2 is a .plan view of the diaper of Fig. 1 in its folded position, with` the edges fastened; Fig. 3 is a plan view of an unfolded trapezoidal diaper having the fastening means fixed to tabs secured to the side edges of the diaper; Fig. 4 is a plan view of the diaper of Fig. 3 in folded position, with the edges fastened; Fig. 5 is a section view taken along line 5--5 of Fig. 4; Fig. 6 is a plan view of an unfolded rectangular diaper having tie string fastening means on the side edges; Fig. 7 is a plan view of the diaper of Fig.. 6 in folded position, with its side edges secured together; Fig. 8 is a plan view of the trapezoidal diaper of Fig. 3; Fig. 9 is a plan view of the diaper of Fig. 8 in folded position, with the side edges secured together; Fig. 10 is a plan view of another Iunfolded contour type diaper; Fig. 11 is a plan view of the diaper of Fig. 10 in its folded position, with the edges fastened; Fig. l12 is a plan view of another contour ty-pe diaper in vfolded position; Fig. 13 is a plan View of the diaper of Fig. 12 as secured in use; Fig. 14 is a plan View of another unfolded contour type diaper; Fig. 15` is a plan view of the diaper of Fig. 14 in its folded position; Fig. 16V is a section View taken along line 16--16 of Fig. l5; Fig. 17 is a .plan View of another unfolded contour type diaper; and Fig. 18 is aA plan view of the diaper of Fig. 17 in folded position.

Referring now to the drawings, there are shown sev-v eral conventional diapers of various configurations in which my invention has been incorporated. `ln Figs. 1- and 2, for example, there is shown a conventional fitted, contour type diaper 1 having a top or seat portion 10l adapted to cover the lower back and sides of the infant, a bottom portion 11 adapted to cover the abdomen of the infant and sides 12 and 13 which. pass between the infants legs. yIf desired, an extra thickness of materia-l may be included at the body 14 of the diaper in order to achieve additional absorbency. To prepare the diaper for application according to my method, the central portion of the side edges are longitudinally folded in wallet fashion at 12b and 13b respectively, so `as to extend in- Lwardly over the body 14 of the diaper 1.. top portion 10 and bottom portion 11 unfolded the diaper assumes the configuration of an airplane with the folded edges 12b and 13b forming a fuselage between the wings or seat portion 10 and the tail section or Vabdomen-covering portion 11. While the folded edges 12b and 13b are illustrated as being parallel, they may if desired converge toward the bottom portion 11 of the diaper. When the side edges 12 and 13 are folded in this manner over the body 14 of the diaper, there is presented a crotch covering portion of reduced width having a double material thickness. My airplane fold additionally :presents a natural pocket 15 between the infolded side edges 12 and 13 and the seat or back covering portion of the body 14 of the diaper. When the diaper is applied, the pocket 15 is presented to the rectal area of the baby with only the outwardly turned portions 12a and 13a of the side edges snugly contacting the infant in that region, thus providing a loose fitting receptacle for waste. `It is obvious that since the body 14 of the diaper is spaced by the outwardly turned portions 12a and` 13a of the side edges from the babys rectal area, the infants bowel movements are less strained and subsequent cleaning of both the diaper and the baby are facilitated. lt is further apparent that the `pocket 15 is readily adaptable for the reception of With the to facilitate folding the diaper to airplane contiguration and to retain the shape and, hence, the utilitarian function of the waste pocket 15. By'way of illustration, I have shown, on myV improved diaper, several embodiments of such fastening means, all of which are part of my generic inventive concept. In the embodiment shown in Figs. l and 2, the fastening means 16, 17 are secured directly to the face of the diaper immediately adjacent to the side edges 12 and 13 and intermediate the top and the bottom 11 to secure the central portions of the side edges together to properly form the Waste trap or pocket 15. The fastening device 16, 17 may be, for example, a button, a releasable snap, a hook and eye assembly or any other conventional fastener.

Referring next to Figs. 3 to 5, there is shown a conventional diaper 2 of trapezoidal configuration, in which my invention has been incorporated, having a seat portion 20, front portion 21 and side edges 22 and 23.

` When the diaper 2 is folded, as shown in Fig. 4, the intermediate portions of the side edges 22 and 23 are folded toward each other in near abutting relationship to present the pocket 25 for the reception of waste or additional padding, as well as extra absorbent areas 22a, 23a of a double thickness of material. To releasably secure the side edges 22 and 23 in this pocket-,forming position, a modiiied form of fastening means are provided. Cooperating fastening means 26, such as are used in the embodiment of Figs. 1 and 2, for example, are fixedly secured to a narrow strip of relatively strong material which is subsequently cut to short lengths and folded over to form tabs 27 of double thickness. The ends of these tabs are then sewn into the side edges 22 and 23 of the diaper 2 as shown in Fig. 5. Securing means 26a are used to mount the fasteners 26 through only the bottom layer or thickness 27a of the tab so that the top layer 27b covers any otherwise exposed portion of the securing means 26a. As thus applied, when the snaps or fasteners 26 are secured together they are completely covered so that no metal touches the babys skin when the diaper is applied. The tabs 27 are preferably made of a fine Weave material such as broadcloth, having a relatively high tensile strength. It is understood, of course, while this is a preferred means of attaching the fasteners 26, either or both of the cooperating parts of the fastener may, if desired, be applied to a single thickness unfolded tab.

In the modification shown in Figs. 8 and 9, a similar trapezoidal diaper 2 is illustrated having tabs 28 and 29 of a single thickness of material secured to the side edges 23 and 22 respectively. The tab 29, to which is secured one of the cooperating members 26 of the fasten ing device, is folded over and is secured, as by sewing, to the upper surface 24 of the diaper 2. In that way when the diaper is folded as shown in Fig. 9, the side edges 22 and 23 meet in abutting relationship with the tab 28 extending under the opposite side portion 22a so that the cooperating parts of the fastening means 26 are not exposed. Again, as in previous modifications, a pocket 25a is formed between the seat portion of body 24 of the diaper and the intermediate side portions 22a, 23a so as to provide a receptacle for bowel waste or for a pad for night diapering. It is understood, of course, that the other tab 28 may be folded under and secured to the under surface of the diaper if it is desired to have the side edges overlap.

In the modification shown in Figs. 6 and 7, a conventional rectangular diaper 3 is shown having a top portion 30, bottom portion 31 and side edges 32 and 33. Secured to the side edges 32 and 33 intermediate the ends thereof, are tie strings 35 and 36. When the side edges 32 and 33 are folded inwardly at their intermediate portions and opposing tie strings 35 and 36 are interconnected, a pocket 37 is formed between the body 34 0f the diaper and the side portions 32a, 33a. Again, the side edges 32 and 33 meet in abutting, or slightly overlapping, relation to form a double thickness of material at the crotch portion for additional absorbency.

In the modication shown in Figs. l0 and 11, there is a conventional fitted diaper 1 having a top or seat portion 10, a bottom portion 11 and side edges 12 and 13. Spaced inwardly from each side edge, intermediate the ends thereof, is one element 18 of a releasable snap fastener. The other element 18a of each snap fastener is secured to the face 14 of the diaper so that the intermediate side portions of the diaper are secured directly to the face of the diaper to form the Waste pocket 15a. With the snap fasteners spaced from the side edges 12 and 13, the side edges may be folded back as shown in Fig. 1l to cover any exposed portion of the snap fastener.

In Figs. 12 and 13, there is illustrated a diaper already prepared as by any of the previously described means, to form the outline of an airplane. To each end of the waist band forming top portion 10, I secure a row of female snap fasteners 19, three being used in the illustration. To engage the female snap fasteners 19, I provide two parallel rows of male snap fasteners 19a secured to the abdomen covering portion of the diaper and extending parallel to the folded edges 12b and 13b. With the snap fasteners thus disposed, when the abdomen covering portion 11 is folded upwardly (Fig. 13) as when being applied to the baby, any one of the female snap fasteners at each end of the top portion 10 may be selectively engaged with any one male snap fasteners in the adjacent row to adjust both the length of the waist band and the length of the abdomen covering portion. It is to be understood that the parallel rows of male fasteners 19a are secured close enough to the vertical center line of the diaper to be within the fuselage portion of the prepared diaper and are, therefore, particularly adaptable for my airplane folded diaper. The parallel rows additionally function as a guide to aid a person in properly preparing that fold.

In Figs. 14. to 16, there is illustrated a further modification, in which only two buttons are required to cooperatively engage a selected combination of button holes to both prepare the airplane fold and adjustably 't the diaper on an infant. Buttons 41 are secured to the opposite corners on the outer surface of the abdomen covering portion of the diaper. Side edges 12 and 13 of the diaper are first folded back over the outer surface of the diaper so that buttons 41 engage the adjacent button holes 42 and then folded inwardly over the inner surface of the diaper. This presents a prepared diaper of airplane configuration having an extra absorbent fuselage or crotch covering area and the waste pocket as in previous embodiments. In applying the diaper to an infant, the abdomen covering portion 11 is merely folded up to form a waist band with the back covering portion 10. The buttons 41 may be selectively engaged with any button hole 44 at opposite ends of the back-covering portion in order to adjust the length of the waist band.

In the modiiication of Figs. 17 and 18, I provide interlooped tie strings 45' secured adjacent to the intermediate portions of side edges 12 and 13. To apply the diaper, the loops 45 are pulled across the face of the diaper to automatically form the airplane fold with a Waste pocket 15b. When applying the diaper to an infant the loops are twisted around buttons 46 secured to the back portion 11 may be folded over upon itself so that the front portion of the waistband will be fastened below the infants stomach to avoid spreading harmful moisture to innocent areas and to eifect increased comfort, particularly after feeding. As the baby grows, this abdomen covering portion 11 may be gradually unfolded to full size thus providing extreme flexibility in use. In this way, the diaper will grow with the baby and may be used as training pants until the baby is two or three years old. When applied to the baby, the soft, rolled side edges 12b and 13b form the leg holes for the baby, the relatively narrow width of the crotch portion providing eXtra protection without bull(` enough to bow the babys leg and affording a great amount of freedom of movement. Only the outwardly turned portions 12a and 13a of the side edges snugly contact the infants buttocks, and the seat covering portion of the body 14 of the diaper is not in close contact with the infants rectal area. As thus applied, the pocket 17 presents a balloon-type seat for the reception of waste or additional padding, as heretofore described, without binding or otherwise discomforting the infant. The diapers of Figs. 3 to 18 are applied in a similar manner and with concomitant advantage.

While the present invention has been described by reference to the particular modiiications illustrated, it will be understood that those skilled in the art may make further modiiications, therefore, I contemplate that the appended claims cover any such modiiications as fall within the true spirit and scope of my invention.
