Baltimore, Md. FiledJuly 25, 1956, Ser. No. 599,980 Claims. (Cl. 128-287) This invention relates to disposable inserts for diapers which are adapted to prevent staining of the diaper by feces, and its principal object is to provide such disposable inserts which retain the feces while permitting substantially free passage of urinary fluids into the body of the diaper.
One of the problems facing mothers with infants has been that of preventing soiling of diapers with feces; and the conventional method of overcoming the problem has been the use of absorbent paper inserts, which absorb the urinary fluids and prevent passage of the feces. A principal problem with such inserts is that in order to be both non-irritant and highly absorbent for urine, they must be very soft, and consequently lack wet strength so that they are difficult to handle on removal from the diaper, and generally must be put in a toilet bowl with the diaper, and flushed while the diaper is immersed in the water of the bowl.
I overcome this difficulty, in accordance with the present invention, by providing an insert which has sufficient wet strength to allow easy removal and handling, and which is perforated so as to allow passage of the urinary fluids, the perforations being small enough, in the anal portion of the insert, to retain the feces. Most preferably, the perforations are larger or more numerous in the non-anal portion of the insert to allow more rapid passage of urine through the insert into the diaper portion.
In another form of my invention, the insert can be combined in a single sheet with a disposable urine resistant insert which acts to prevent urine from passing completely through the diaper on overnight contact (as disclosed in my copending application Serial No. 415,74], filed March 12, 1954, now Patent No. 2,860,637) and the combination so folded into the diaper that the per forated urine passing portion is placed next to the infants skin, while the urine resistant portion of the insert is placed near the outside fold of the diaper.
The invention can best be understood by reference to the accompanying drawings, in which FIG. 1 shows an insert in accordance with my invention in which the perforations are uniformly spaced throughout the insert;
FIG. 2 shows an insert with a variable spacing of perforations;
FIG. 3 shows an insert with variable sizing of perforations;
FIG. 4 shows a two part insert ready for folding into a diaper;
FIG. 5 is an elevation of a folded diaper with the insert of FIG. 4 in it.
Referring to FIG. 1 of the drawings, I provide a diaper insert of wet strength material with uniform perforations 12 thereon. The perforations are small holes, preferably pin holes,-which permit the passage of liquid while retaining solid matter. I have found that in ordinary sheet material, holes up to about 1 to 3 mm. in one dimension, or diameter, will retain feces; but a large number of pinholes will pass urine just as effectively as a small number of larger holes. The holes can be round, elliptical, slitted, or in any convenient and useful shape.
In FIG. 2, it will be noted that the perforations 32 are almost non existent at the top of the insert, and are very numerous at the bottom. This'insert is placed with the top portion at the back, anal end of the diaper, and the forward portion at the point of urine discharge. I
prefer to have a few-perforations even at the ana-l endyto remove liquid; but this is not essential, since the' highly perforated forward end removes the urine rapidly as it is discharged, so that it can be absorbed by the diaper proper.
FIG. 3 shows the use of larger holes 14a: the point of urine discharge, with the pin holes 12 at the anal end of the diaper. 7
As indicated above, it is essential-that the insert have sufiicient wet strength so that it can be lifted or pulled in the presence of water, such as wet strength papers, and supported and non-supported waterinsoluble films,-
for example cellulose acetate, ethyl-cellulose, polyethylene, polyvinylidene chloride, and the like 'water' insensitive films. But my preferred materials are those which, while insoluble in water, are pervious to water vapor and are capable of swelling in water. phane), partially saponified polvinyl acetate, polyvinyl,
acetate, films in which water sensitive swelling agents, such as methyl cellulose and other cellulose ethers, are intro.-
duced in quantities making the substrate water sensitive,
carboXy-methyl cellulose, and insolubilized proteins, such as HCHO treated gelatine and zein, are examples of such materials.
The fact that the films are pervious to water vapor permits breathing, making the diaper more comfortable than rubber pants. The property of swelling in water perrlnits the materials to soften in a toilet bowl and flush easi y.
The thickness should be kept low' as possible and is only limited by the ease of handling, strength and wet strength of the material. I have found, that the lower limit is about one thousandth of an inch and I prefer to use thickness between 5 and i5 thousandths of an inch.
My inserts, in addition to the advantage of ready removability, have a second important advantage. Once the urine passes through the holes and is absorbed by the diaper, the child is protected from the bulk of the sodden diaper by the insert. This is particularly true in the case of those materials which are water impervious (the plastics and cellophane). A baby who urinates into a diaper with my insert ,will be much more comfortable than a bady who urinates into an unprotected diaper or one with conventional inserts.
As shown in FIGS. 4 and 5, my inserts can he modified so as to provide protection for bed clothes, and outer garments, and effectively overcome the need for rub ber pants. The insert as shown has the form of insert It) shown in FIG. 3, with pinholes 12 for the anal portions and larger holes 14 for the urinary portion. Integral therewith is an unperforated portion 16. A diaper 18, with sections A-BCDEF, is shown. The portion in of the insert is placed over portion E of the diaper, and the half ABC folded forward. A-F is then folded centrally over B, and C-D folded centrally over F, and finally the forward 20 portion of the insert It} is folded over D. The resultant diaper is shown in FIG. 5 and includes a completely urine retarding ply 3.6, with 5 diaper plies above it to absorb urine, and a urine passing feces retentive ply 20 to protect the diaper.
This form of the invention has the advantage that it can be withdrawn or lifted from the soiled diaper as a Patented J an. 15,1963 i Hydrated cellulose (cello- I nit and disposed down a toilet drain, practically without touching the wet diaper.
For this form of the device, at least the impervious portion of the insert must be of urine impervious material. I may use the various plastic films described above but again I prefer to use the water-swellable water insoluble films such as cellophane, polyvinyl acetate and the like. If desired, the lower halves of these inserts may be coated with wax, polyethylene etc. to improve their resistance to water; but care should be taken that the films are still disposable and the coating is very thin, to permit breathing. This two piece embodiment of my invention has the additional advantage that the insert is kept in position under the infant and can not slip to a position not protecting the diaper.
Obviously, changes can be made in the specific forms of my invention disclosed without departing from the scope thereof as defined in the claims.
I claim:
