3 Claims.v (Cl. 128-284) This invention relates to improvements in diapers.

It is an object of the present invention to provide a very eflicient, economical, practical diaper with intermediate liquid repellent layer for babies, invalids, and hospitalized persons.

It is another object of the present invention to provide a diaper in which the water repellent member is coterruinous with the moisture absorbent members.

It is another object of the present invention to eliminate the use of extra rubber of plastic panties which usually causes chafing and irritation to the babys waist and/or thighs.

Another object of the present invention is to provide a diaper shaped to the baby's form which is adjustable from infant to large size.

A still further object ofthe present invention is to provide a diaper with intermediate water repellent layer in which is contained a plurality of moisture-absorbent elements positioned in such manner in relation to the outer and inner layers that they will always be under the babys buttocks when the diaper is adjusted on the baby.

Yet another object of the present invention is to provide a diaper made up of a plurality of plies, one of which is a water repellent layer, and in which the plies are seamed together on two sides and one end leaving the other end open to facilitate drying of the diaper after being washed.

Another object of the present invention is to provide tabs at the closed end of the diaper for facilitating attachment of the diaper to a shirt or the like, and also for use to hang the diaper to a clothes line preventing the diaper from becoming soiled which would happen if the diaper was hung directly on a usually soiled clothes line.

A still further object of the present invention is to provide a diaper having a flexible water repellent receptacle for retaining the babys waste matter or excretions.

The above and other objects, features and advantages will appear from the following detailed description and in the accompanying drawings illustrating modes of carrying out the invention. It is understood, however, that it is not intended that the invention be limited to the exact details described herein which illustrates satisfactory diapers of many which may be produced as a result of the knowledge gained through or gleaned from an understanding of the invention, and it is further understood and intended that there be included, as part of the invention, all such obvious changes and modifications thereof, as would occur to a person skilled in the art.

Fig. 9 is ,a cross-section taken along line 9-9 of Fig. 8; and

Fig. 10 is a perspective view of the modification shown in Figs. 7, 8 and 9.

Reference will now be made to the various examples by which the invention is realized. Referring to Figs. 1 to 5, inclusive, there is disclosed a diaper 15 comprising an outer layer or member 16 and an inner layer or member 17, these members being made of any conventional liquid absorbing sheet material or diaper cloth or at least the inner layer 17 being made of such material, and being of conventional hour-glass shape with incurved or concave portions as indicated at 18. These members may be plain white in color or may incorporate any desired design or figures to give the diaper an aesthetic appearance. The outer layer 16 is preferably provided with the female elements 24, 25 of snap fasteners and the inner layer with the complementary male elements 22, 23 of said snap fasteners.

A plurality of layers of liquid absorbing material, such as diaper cloth, are seamed at their ends to the inner face of inner layer 17 by means of the stitches 27, 27', constituting a pad 21. The sides of pad 21 are preferably arcuate and extend inwardly from the sides of the outer and inner layers 16, 17 and these sides are preferably free of securement so as to prevent puckering thereof or folds or creases being formed therein. The pad 21 is shorter than the inner and outer layers at both ends. At the seam 27 the pad 21 is preferably tapered forming an extension for the male genitals if the diaper is used on a male.

Interposed between the outer layer 16 and the pad 21 which is secured to the inner layer 17, is a sheet of liquid repellent, moisture blocking material 20. Material of this type is well known in the art andneed not be described herein. However, sheet or layer 20 is of the same size and shape as the inner and outer layers or members 16, 17 and the three layers 16, 20 and 17 are seamed together substantially around the periphery of the diaper at their folded-over margins 16a, 20a and 17a, respectively, by the peripheral line of stitches 26, except at the end 29a of the diaper where an opening 29 is provided at the termini 30 of the seam 26 to facilitate drying of the diaper when washed. The line of stitches 26 beyond the termini 30 continue only on inner layer 17 as seen at 26a, Fig. 2, holding down the folded edge thereof and providing a finished edge thereat. Secured to the closed and somewhat wider end of the diaper are the loops or tabs 28 to facilitate the diaper being secured to a shirt of the wearer.

Fig. 5 illustrates the folded condition of the diaper when adjusted upon the wearer, the portions 19, 31 and 32 of Figs. 1 and 2, forming respectively the flaps 19a, front 31a and rear 32a of Fig. 5. Adjustment as to size upon the wearer may be accomplished by means of the complementary snap fasteners 22, 23, and 24, 25.

Fig. 6 illustrates the invention in a somewhat modified form, wherein the diaper is generally indicated by the numetal 15'. In, this form at the invention the liguid repel- 9 lent,--moisture blocking sheet *or layer 20- is disposed on the outside of the diaper rather than between the inner and outer layer asseen in Figs. 1 to 4, the pad 21 being locat'ed as shown in said figures.

Figs. 7 to 10, inclusive disclo'ses the invention in a still further rnod'ified- 'fdrm. The diaper body 'rnay 'be of construction 'similarto that shown in Figs.1 to 4 and' like parts ar'e indicated accordingly. The outer and inner liquid"absorbinglayers "16 and 17- respectively, and the intermediate liquid repellent layer-20 are coextensive and areseamed together by the stitches '26,"except at the central portion of the narrower end indicated by the numeral35,which' portion is' open similar to that as'indicated at 29 in Fig. 3. Thelayers forming thepad 21*are seamed at'their ends by the stitches -27 and 27'. Disposed over the inner layer is a liquid repellent receptacle or catch device 36in which maybe disposed the absorbent paper or cellulosic sheet 41. The excrement or waste matter of the'user of the diaper will 'be'received in receptacle 36 and deposited on the absorbent sheet 41, the latter containing the deposit-being easily removed from the receptacle and discardedwhen the diaper is removed from the body of the wearer.

Receptacle 36 which may be cylindrical or oval is made ofcon'ventionalflexible liquid repellent material and is provided with a'bottom38 and av peripheral wall 37 bothof which are seamed together at their fold-over margins 37" and-38" by the stitches 39 and 40. It is preferable for stability to make the wall 37 two-ply by folding-the material upon itself as indicated at 37. It is preferable to'make receptacle 36oval 'in shape and it may be disposed with relation to inner layer 17 with its major axis transversely thereof as shown in Fig. 8 or with its minor axis transversely of inner layer 17.

It is apparent that there has herein been provided diapers which are very efiicient, practical and useful and which attain the purposes and advantages contemplated by the invention. It is understood that the liquid repellent or waterproof layer may be eliminated from the diaper.

While the-inventionhas been described and illustrated with respectto'some particular preferred examples which givesatisfa'cto ry results, it'willbe understood by those skilled in theart after'under'standing the principle of the invention, that'various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended, therefore, in the appended claims to' co'ver all su'ch changes'and'modifications.
