SANITARY NAPKIN Filed Jan. 4, 1963 Nw wm ww INVENTOR.
cd1?? Jon m, hm
United Statesl Patent O 3,203,419 SANITARY NAPKIN Curt G. Joa, Ocean Ridge, Fla. (Box 1121, Boynton Beach, Fla.) Filed Jan. 4, 1963, Ser. No. 249,367 2 Claims. (Cl. 128-290) This invention relates to an improved sanitary napkin. An important feature of the sanitary napkin embodying the present invention is the combination of a non-woven relatively fragile and soft outermost wrapper for the absorbent ller pad, with relatively strong reinforcing strips, desirably one at each side of the filler pad and between the ller pad and the soft non-woven outer wrapper. Because of its softness, it has been found desirable to use a nonwoven fabric Wrapper, but this wrapper is insuiciently strong to resist stresses. The strips of reinforcing material desirably consist of commercially available gauze or non-woven fabric which is stronger than the non-woven fabric of the wrapper. These give ample strength to the sanitary napkin and the resultant product is of low-cost construction and retains the desirable soft non-woven outermost wrapper.
An optional, but desirable, feature of the invention is a plastic strip between the outermost Wrapper and the side of the ller which is away from the body when worn. The plastic strip functions as a moisture barrier and supplements the reinforcing strip in adding strength to the napkin. The plastic strip is desirably heat scalable. The reinforcing and plastic strips extend beyond the ends of the filler pad to comprise attaching tabs. The tabs are heat sealed adjacent the ends of the iiller pad to hold the fabric tucks snugly around the napkin pad and maintain the shape of the napkin.
Other objects, advantages and features of the invention will appear from the following disclosure in which:
FIG. 1 is a perspective view of a sanitary napkin ernbodying the invention, the several plies of one of the attaching tabs being separated to show the assembly of the strip components thereof.
FIG. 2 is a longitudinal cross section taken through a sanitary napkin embodying the invention.
FIG. 3 is a cross section taken along the line 3--3 of FIG. 2.
FIG. 4 is a diagrammatic view showing the method by which a napkin embodying the invention is fabricated.
Although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention, the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure. The scope of the invention is defined in the claims appended hereto.
The sanitary napkin comprises one or more layers of absorbent iller pad material surrounded by an outermost wrapper 11 of non-woven fabric which is soft, but which lacks substantial strength. The edges of the wrapper 11 are brought together along seam 12 along the medial center line of the side of the napkin worn away from the body, the seam being sealed by a bead or ribbon 13 of thermoplastic material. Sanitary napkins such as hereinbefore described are shown in my copending United States patent applications Serial No. 95,767, filed February 2, 1961, and Serial No. 184,105, led April 2, 1962.
In the preferred embodiment, the relatively fragile or weak non-woven fabric wrapper 11 is reinforced by two strips 14, 15 of relatively strong material. In the preferred embodiment, strips 14, 15 constitute commercially available gauze. These are centered upon the medial center line of the napkin and have a width equal to about one-half the width of the ller pads 10.
I also provide a strip 16 of thermoplastic material, sub- 3,203,419 Patented Aug. 31, 1965 stantially the same width as gauze strip 15. Only one strip 16 is provided and this is disposed within the napkin to lie between gauze strip 15 and filler pad 10. Strip 16 is thus disposed at the side of the napkin away from the body when worn. It functions as a moisture barrier and further reinforces the napkin at its exposed side.
The various plies of the Wrapper 11, gauze strips 14, 15 and plastic strip 16 extend beyond the ends of the filler pads 10 to constitute attaching tabs 17, 18 at both ends of the napkin. The several plies of gauze and plastic in the attaching tabs 17, 18 provide ample pinning strength. The excess material of the wrapper 11 is desirably tucked closely adjacent to the ends of the ller pad 10 and the tabs 17, 18 are heat sealed at 19, 20 adjacent the ends of the ller pad. If desired, the entire area of the end tabs may be heat sealed to bond the threads of the gauze strips 14, 15 to the intervening plastic strip 16 and to the wrapper material 11, thus to greatly increase the overall strength of the tabs.
The heat sealing aforesaid holds the ller pads 10 in position and also maintains the tucks of the fabric snugly around the pad in a neat appearing package.
Sanitary napkins embodying features of the invention can be readily fabricated on conventional machinery. FIG. 4 illustrates a continuous fabrication operation in which the ller pads 10 are entubed within the wrapper 11, the gauze strips 14, 15 and the plastic strip 16 being unwound from parent rolls concurrently with the advance of the filler pads 10 are propelled by traveling belts 23, 24.
While the preferred construction incorporates two reinforcing strips 14, 15, under some conditions I may omit the strip 14. This will leave gauze strip 15 and the plastic strip 16 to reinforce the napkin. Both of these strips will be disposed on the side of the napkin away from the body and proximate the seam 12.
Edge wrap strips, as shown in my United States Patent 2,721,554, may optionally be incorporated in napkins embodying the present invention.
The heat seals 19, 20 may be formed by conventional apparatus, for example the rollers 25, 26, which carry heat seal bars 27, 28.
The thermoplastic seal 13 is formed by the apparatus shown in my copending application Serial No. 95,767 aforesaid and is indicated by reference character 29 in FIGURE 4.
As aforestated, the reinforcing strips 14, 15 may be made of non-woven fabric of a heavier gauge than the soft fragile wrapper 11. Such a non-woven fabric is amply strong to reinforce the wrapper and in some instances is preferred over gauze.
I claim:
1. A sanitary napkin comprising:
(a) a filler having opposed broad sides and opposed narrow sides,
(b) a relatively weak non-woven fabric wrapper about the filler,
(c) two strips of reinforcing material, one at each of the broad sides of the filler and between the filler and said wrapper, said strips being narrower than the width of said broad sides,
(d) a strip of thermoplastic material substantially coextensive with and between one of said reinforcing strips and the side of the filler away from the body when worn,
(e) said strips extending beyond the ends of the filler to a comprise attaching tabs,
(f) and heat seals in said tabs adjacent the ends of the fil er.
2. The sanitary napkin of claim 1 in which said wrapper has its side edges seamed along the medial center line 3 4 of the napkin and a thermoplastic seal between said edges, 2,578,664 12/ 51 Beery et al. 128-290 said seam being at the side of the napkin away from the 2,773,503 12/56 Brownlee et al 128-290 body when worn. 2,896,627 7/59 Harwood 128-290 References Cited by the Examiner 5 1 FORIGNBIATENTS UNITED STATES PATENTS 648,141 2/50 reat ritaln. 1,980,958 11/34 Rohlng 12g 290 RICHARD A.
