Application February 7,
This invention relates to improvements in disposable sanitary napkins.
Another object can be readily disposed of after it has been used, thereby obviating the necessity of cleaning.
A further object is to produce an absorbent pad or sanitary napkins of said construction that a deodorant powder can be applied thereto and positioned thereon.
A still further object is to produce an absorbent pad of such construction that it can be manufactured by an automatic machine and therefore at a low cost.
Another object is to produce a pad that shall have a layer of nonabsorbent fibrous material near its lower surface to minimize the danger of soiling the supporting portion of the belt and a still further object is to produce a pad having a pocket for containing and positioning a deodorant powder and which can be used with dispos- Having thus briefly pointed out the objects of the invention, the same will now be described in detail, and for this purpose reference will be had to the accompanying drawing in which the invention has been illustrated, and in which:

Figure 10 is a Figure 9.
In the drawing reference numeral ll designates a belt having a front suspending member l2 and a rear suspending member I3. The lower end of member l3 terminates in a supporting pad l4 whose front end is provided with hooks l5 for engagement with the loops of the elastic It in the manner shown in Figure 8.
The belt and supporting member form no part of this invention and have been shown merely for the purpose of more clearly explaining the same.
The pad that forms the subject of this invention and which has been illustrated in Figures 2 to 6, inclusive, is formed from fibrous material, such as soft fibered absorbent paper. The outer surface of the pad is formed by a sheet ll of absorbent fibrous material which, in the embodiment illustrated, is provided with two pleats l8 and I9. Pleat I8 is preferably wider than pleat l9 and the latter serves principally as a closure for the pocket 20 that is provided for the purpose of containing and retaining a deodorant powder. The outer member I! is formed by special machinery or by hand, into a tubular shape, the edges, which have been indicated by reference numeral 2 I are spaced apart 3 and are connected by means of a strip of paper 22 having its outer surface adhesive, for example, rubber cement. Strips of paper having such adhesive surface are commonly sold for the use of draftsmen who employ them instead of thumb tacks because the adhesive does not dry but remains tacky for a long time, which is an important consideration in the present invention. Positioned within the envelope and on top of the strip 22 is a layer 23 of cotton which has been treated with oil or in some other way so as to render it only slightly absorbent; this layer is to some extent moisture proof. The remainder of the pad above the layer 23, is formed from a plurality of layers of absorbent fibrous material of the kind above indicated. This material has been designated by reference numeral Id.
The pad has been designed so as to be suitable for manufacture in long strips by means of automatic machinery and means is provided for cutting the strips into sections of the proper length. It is desirable that the ends of the pad be slightly compressed so as to taper and that they be held lightly in this shape by some suitable means. It is also quite desirable to secure thepleat I 8 at the ends in such a way that it will retain its position during handling and form a pocket for section taken on line lfllfl,
the reception of the deodorant powder. In order to compress and secure the ends in compressed position by the same operation of the machine that effects the cutting, the attachment is effected by means of two punches that penetrate the material forming holes 25, two of which have been shown at each end of the pad. Due to the very fibrous nature of the material, and to its great softness, the action of the penetrating punch is to pull the fibers downwardly into a somewhat tubular form as indicated by reference numeral 26 in Figure 5. This serves to temporarily interconnect the several layers and holds them with sufiicient strength to prevent their opening due to the slight amount of handling to which they are subjected. The tape '21 formed from some suitable material such as Cellophane is positioned over the adhesive surface of strip 22 in the manner shown in Figure 6 so as to guard against material coming into adhesive contact with the strip during handling and merchandis-- ing. Before the pad is used, the strip 21 is removed by exerting thereon a pull in the manner indicated in Figure 6. After the covering strip 21 has been removed, the pad is positioned on the support M, in the manner shown in Figure 8, and pressed against the fibrous surface of the latter, whereupon the adhesive material. will come into operative contact with the upper surface of support M and attach the pad thereto in amanner quite obvious from an inspection of Figure 8. Due to the action of the adhesive strip, the use of safety pins or other attaching means can be dispensed with since the adhesive strip exposed along the lower surface of the pad serves to hold the latter in position with sufiicient force to prevent its accidental displacement even when the hooks at the front of the supporting member [4 are disconnected from the elastic loops.
It is apparent that pads constructed in the,
manner above described and from absorbent fibrous material have, in addition to their large capacity for absorbing fluid, another advantage, namely, that the smooth fibrous surface prevents chafing and discomfort during use. The presence of the cellulose cotton serves to some extent to prevent the soiling of the supporting member [4. Attention is called to the fact that the pad I4 is filled with a fibrous material that has been designated by reference numeral 28 and that this rests on a layer 29 of Pliofilm or some other thin, waterproof material. If the supporting pad l4 does become soiled, it is possible to launder'the same so as to make it suitable for further use.
Particular attention is called to the presence of the pocket 20 that has been provided for the reception of a deodorant powder. Due to this construction,
the deodorant powder can be applied in sufiicient amount to become effective and will be held in proper position by the two pleats l8 and I9, pleat l9 serving more or less. as a closure for the pocket 20.
In Figures 9 and 10, a slightly different shaped pad has been shown which is intended to serve as a diaper for babies. The triangular pad shown in Figure 9, which has been designated by reference numeral 30, has its upper surface provided with two pleats l8a. and We which serve to form a pocket 20a for the reception of a deodorant powder. Aside from shape, and the fact that the diaper is not provided with a strip of adhesive corresponding to 22 in Figure 3, the diaper has the important characteristics of the pad above described.
A diaper formed from absorbent fibrous material and provided with a pocket for deodorant power is very convenient and is readily disintegrated when subjected to the action of water, wherefore it is admirably suitable for use as a disposable diaper which obviates the necessity of laundering.
Absorbent pads of the kind and construction above described can be manufactured at a comparatively low cost, almost entirely by automatic machinery and since very little, if any cotton, is employed, the material necessary is readily available and therefore avoids the delay incident to obtaining the ordinary cotton material usually employed for this purpose.
Particular attention is called to the presence of the adhesive surface 22 and the pocket 20 for the reception of the deodorant powder. The presence of the cellulose cotton layer 23 between the absorbent filling 24 and the adhesive strip 22 is also of considerable importance as by the use of this material a pad is obtained that retards, to a great extent, the penetration of fluid through the bottom thereof.
Having described the invention, what is claimed as new is:
A disposable absorptive sanitary pad comprising, an envelope formed from a sheet of fibrous material bent to form a tube, the adjacent edges of the sheet being spaced apart, means for connecting the adjacent edges comprising a strip of material having its outer surface provided with an adhesive, said strip being positioned within the envelope in overlapping relation to the spaced adjacent edges, the adhesive material exposed between the adjacent edges serving as means for attaching the pad to a supporting member, and a filling of absorbent material in the envelope.
