No. 373,247 filed June 25, 1973, and now abandoned.
BACKGROUND AND SUMMARY OF INVENTION Increasingly those in the art of producing disposable diapers have striven to provide suitably prefolded diapers so that the diaper conforms readily and fits comfortably on the infant.- Exemplary of this are the diapers seen in US. Pat. Nos. 3,196,874 and 3,710,797. The diaper of the instant invention is an improvement on the diapers in the above-mentioned patents.
The inventive diaper and apparatus therefor provide interrupted transverse and foreshortened angled convergent lines of compression so as to develop a single legfold diaper and with legfold adhesive adjacent the interrupted angled convergent lines of compression to develop a natural drape of the outer center portions.
DETAILED DESCRIPTION:
The invention is described in conjunction with an illustrative embodiment in the accompanying drawings, in which:
FIG. 1 is a plan view of a diaper blank prior to foldmg;
FIG. 2 is a plan view of the folded diapers;
FIG. 3 is a side elevational view of the diaper of FIG. 2; and
FIG. 4 is a plan view of the unfolded diaper showing the various stress lines;
In the illustration given, and with reference first to FIG. 1, the numeral designates a diaper blank. By this, I refer to the precursor of the final disposable diaper, but one wherein the essential, conventional elements are already assembled. For example, the blank 10 includes an outer impermeable sheet 11, a layer of liquid absorbing material, and an inner liquid permeable sheet, .all united perimetrically. Such blanks are provided in a connected stream (prior to scoringand adhesvie application). Conventional apparatus is available for the production of such a multi-ply diaper web.
The diaper blank in FIG. 1 is seen to include a plurality of lines of compression, i.e., lines of incipient folding. First, reference is made to an interrupted, centrally positioned, transverse line generally designated 12 which includes line segments 12a and 12b. The middle portion of the line 12, i.e., the interrupted portion designated 120 in FIG. 1, provides a crotch-forming portion P of the diaper (see FIG. 4) which is relatively rounded and unstressed, and which has excellent containment characteristics. The development of fold lines as by compression, creasing, etc. may impair the containment characteristic, and, in extreme cases, result in leakage.
Associated with each line segment 12a or 12b, as the case may be, are a first pair of inwardly convergent, foreshortened lines of compression and which are disposed at about 45 relative to the associated line segment. As can be readily appreciated from FIG. 1, the angled lines associated with the line segment 12a are designated 13 and 14, while thos associated with the line segment 12b are designated and 16. It will be seen that if the lines 13 and 14 were extended, they would converge on the line 12, the same being true in the case of the lines 15 and 16. The foreshortening'aids in developing the advantageous unstressed crotchforming portion.
Associated with each line segment 12a or 12b are a second pair of inwardly convergent, foreshortened lines of compression disposed at about 22 /2 relative to the associated line segment. For example, lines 17 and 18 are associated with segment 12a with line 17 being positioned between line 13 and segment 12a. Line 18 is between line 14 and segment 12a. In like fashion the lines 19 and 20 are positioned relative to the segment 12b and its first pair of lines 15 and 16.
Adhesive may be applied by an applicator of conventional design in the spots designated 21, 22, 23, and 24 in FIG. 1, with each spot 21-24 being adjacent a longitudinal edge, but spaced inwardly therefrom, and also adjacent to but spaced from an associated convergent line of compression 13-16, respectively. Before leaving FIG. 1, reference is *made to the tabs 25 and 26 which are provided in conventional fashion to secure the diaper in place about the infants waist, and which are conventionally provided on the diaper web 11 upstream of the scoring and adhesive applicator rolls.
Referring now to FIG. 4, the diaper is seen in its partially unfolded condition and designated D the folded configurations being designated D in FIGS. 2 and 3. It is in this configuration that the diaper is ready to receive the body of an infant. The foreshortened lines of compression 13-20 cooperate with the interrupted portion of the line 12 to define the relatively rounded, unstressed crotch-forming portion the absence of intentional creasing, but the presence of slight rounding being illustrated in FIG. 4 by means of a series of lines in the central portion P. I
Still referring to FIG. 4, the points of adhesive (as at 21 and 22) develop an imaginary line 24 which ultimately becomes a rounded leg outfold when the diaper is applied to the body of an infant. It will be appreciated that the term outfold is used in contrast to an infold which is developed, for example, along the lines 13, 12a and 14, viz., where theconfronting, abutting faces of the fold are the inner liquid permeable sheet. Contrarily, the lines, l720 define oudolds. However, up tothe time of applying the diaper to the infant, no outfold exists alongthe imaginary line 24, but instead, a relatively flat or thin wing as at W (see FIG. 2) exists. Thus, the provision of the various lines of compression, along with the adhesive spots, not only develops a thin, advantageously packageable diaper, but one which re sults in the provision of a body-conforming leg outfold. The advantageous thinness or compactness can also be appreciated from FIG. 3 which represents the diaper D in a partially unfolded condition, and wherein there is an infold at 12b, 15 and 16, and an outfold at 19 and 20. The outfolds 1740 thus cooperate with the infolds 12a, 12b and 13-16 in developing a readily contourable leg portion on the diaper.
I claim:
1. A generally rectangular disposable diaper comprising an outer impermeable sheet, a layer of liquid absorbing material and an inner liquid permeable sheet all united perimetrically,
said diaper having a central transversely extending interrupted line of compression whereby the diaper is adapted to be folded on itself to provide a crotchforming portion in the middle of said interrupted line of compression,
said line having a segment extending in from each lopgitudinal edge with each segment terminating short of the crotch-forming portion of the diaper, first pair of inwardly convergent foreshortened lines of compression associated with each of said segments and disposed at about 45 relative thereto, and a second pair of inwardly convergent foreshortened lines of compression associated with each of said segments and disposed at about 22V2 relative thereto, each of said convergent lines of compression extending in from each longitudinal edge but terminating short of the crotch-forming portion of the diaper and short of the inner end of its associated segment and cooperating with said associated segment to provide a relatively rounded,
pair of convergent lines of compression.
