Definitions
- Sanitary napkins of conventional form include an elongated absorbent core wrapped within a liquid previous covering material which extends beyond the end-s of the core to form tabs for attaching the napkin in position on the body of the wearer. Due to the manner in which the covering material is wrapped around the core, the attachment tabs are usually simple flattened extensions of the covering material, having substantially the same width as the width of the absorbent core around which the cover is wrapped. In view of the tab dimensions, it is customary to first rope or bunch up the tabs before attaching a napkin having such tabs in position by pinning or by fitting the tabs into a clasp on a sanitary napkin belt or the like. This practice is not satisfactory in that the tabs are thus made bulky and may be uncomfortable. Further, the random manner in which the tabs are roped or bunched may result in insecure attachment of the napkin.

Feb. 5, 1963 N. A. HARRISON 3,076,459
SANITARY NAPKIN Filed Dec. 16, 1959 ATTO NEY United States Patent U 3,076,459 SANITARY NAPKIN Norman A. Harrison, 01d Bridge, N.J., assignor, by mesne assignments, to Johnson & Johnson, New Brunswick, N.J., a corporation of New Jersey Filed Dec. 16, 1959, Ser. No. 860,028 4 Claims. (Cl. 128-290) This invention relates to sanitary napkins and more particularly to sanitary napkins having folded attachment tabs.
Sanitary napkins of conventional form include an elongated absorbent core wrapped within a liquid previous covering material which extends beyond the end-s of the core to form tabs for attaching the napkin in position on the body of the wearer. Due to the manner in which the covering material is wrapped around the core, the attachment tabs are usually simple flattened extensions of the covering material, having substantially the same width as the width of the absorbent core around which the cover is wrapped. In view of the tab dimensions, it is customary to first rope or bunch up the tabs before attaching a napkin having such tabs in position by pinning or by fitting the tabs into a clasp on a sanitary napkin belt or the like. This practice is not satisfactory in that the tabs are thus made bulky and may be uncomfortable. Further, the random manner in which the tabs are roped or bunched may result in insecure attachment of the napkin.
It is an object of this invention to provide a sanitary napkin having attachment tabs which are pre-folded. It is another object of this invention to provide sanitary napkins with attachment tabs which are neat in appearance and which may be readily secured in position by attaching to a sanitary napkin belt or by pinning. It is a further object of this invention to provide a sanitary napkin having attachment tabs of increased strength. Other and further objects of this invention will become apparent from a consideration of the following specification and attached drawing.
In the drawing:
FIG. 1 is a perspective view of a sanitary napkin incorporating the invention;
FIG. 2 is a sectional view, on an enlarged scale, taken along lines Z2 of FIG. 1;
FIG. 3 is a perspective view of a folding device and illustrates the manner in which the tab portions of the napkin may be folded;
FIG. 4 is a view in elevation of the tab portion of a napkin being folded by the folding device; and
FIG. 5 is a view in elevation of the absorbent core portion of a napkin passing through the folding device.
In accordance with the invention, the tab of the napkin is folded in the shape of a flattened 2, the extent of folding becoming increasingly greater from the end of the core of the napkin to the end of the tab. 7
Referring to the drawings, a sanitary napkin 10 comprising an elongated, generally rectangu-larly shaped core 12 of an absorbent material such as cotton, comminuted wood pulp fibers, paper and the like, is enclosed within a cover 14 of sufficient width to envelop the core, with the longitudinal side edge portions 16, 16' of the cover overlapping on an upper or lower surface of the core. Preferably, the overlapped side edges of the cover are positioned on a surface opposite the surface which is placed against the body when the napkin is in use. The cover is of sufficient length to extend beyond the ends of the absorbent core to form tabs 18 at each end for attaching the napkin in position on the body of the wearer. The tabs may be of the same or diiferent lengths.
The tabs, which are initially of approximately the same width as the absorbent core, are folded in the form of a 3,076,459 Patented Feb. 5, 1953 fiattenedz as illustrated in FIG. 2, by folding the tab in a zig-zag manner, to form three sets of plies, 20, 22, and 24, in the tab. The degree and extent of folding may be varied but preferably tapers down from the end 26 of the core to the end of the tab to minimize squeezing and reduction in bulk of the core.
By folding in the manner noted above, the multiply form which results imparts increased strength and resistance-to tearing to the tabs when the napkin is attached. In addition, the folding provides neat tabs which may be more readily pinned and threaded through cla-sps and which are less visible and bulky than the bunched tabs of conventional size and configuration.
A device for folding the tabs of sanitary napkins incorporating the invention is illustrated in FIGS; 3-5. A pair of spaced vertically mounted shafts 28, 28 which revolve in directions opposed to each other at substantially equal speeds have attached thereto rigidly mounted horizontally positioned substantially fiat folding blades 30 and 32 which may be of a flexible material, such as a heavy layer of vulcanized rubber, or of metal, plastic or the like. The folding blades are substantially semi-circular in shape and project radially from the shafts.
The size of the folding blades and the location of the shafts are so selected with respect to each other that the folding blades move in a manner to come opposite and then awayfrom each other at each complete revolution of the shafts, thereby first narrowing the space between the shafts and then enlarging the space. To provide a 2 shaped fold in the napkin tabs, the outer edge portion of folding blade 30 is beveled downwardly and inwardly as at 34 at an angle from the top surface thereof and the outer edge portion of the folding blade. 32 is similarly beveled but upwardly and inwardly as at 36 from the bottom surface thereof so that the two blades when opposite each other have their beveled surfaces in substantially matching relationship but somewhat spaced from each other. The top surface of folding blade 20, the intervening space between the beveled surfaces of the blades and the bottom surface of folding blade 32 define a Z-shape. It will be thus observed that when the folding blades are opposite each other, they fold the cover portion extending between an adjacent pair of absorbent cores into a Z-shape, the cover portion so extending being the portion which forms the tab portions of the sanitary napkin, and fol-d the cover portion as the cover portion moves past and between the folding blades. The peripheral length of the folding blades is preferably slightly less than the length of the cover which extends between an adjacent pair of absorbent cores.
In operation, the elongated cover of continuous length folded around and containing a plurality of absorbent cores which are spaced apart lengthwise within the cover, passes between the opposed, spaced apart vertically mounted shafts. The cover containing the spaced absorbent cores is moved longitudinally and its movement so correlate-d to the cyclic movement of the folding blades that the blades engage the longitudinally extending sides of the cover extending between an adjacent pair of absorbent cores to produce the fold in this cover portion. Each rotation of the shafts, and thus the folding blades, produces a fold in the cover portion between an adjacent pair of absorbent cores. As an absorbent core approaches the folding blades, the blades are rotated out of. contact with the cover portion to provide a free space between the shafts to enable the absorbent core to pass through without compression or folding. Directly after an absorbent core has cleared the shafts, the folding blades are rotated into folding contact with the cover portion extending between an adjacent pair of absorbent cores at or adjacent the end of the absorbent core which has just cleared the shafts. As the cover portion extending between the adjacent pair of absorbent cores moves through the folding device, the folding blades rotate into engagement with the cover portion and progressively fold the cover portion between the absorbent cores and contin-ue until the next absorbent core is moved into the folding device whereupon, as noted above, the folding blades are rotated out of contact with the cover. The synchronized movement of the cover material containing the spaced absorbent cores is such that the cover portion extending between an adjacent pair of absrbent cores is pleated or folded in the manner described whereby sanitary napkins having folded tabs may be efficiently massproduced. 7
Preferably, a compressing or ironing device is posi- -tioned directly after the folding operation to press the folded tabs to provide a neat and finished fold. The pressing operation may be accomplished in various ways. The drawings disclose a horizontally disposed upper roller 38 and a horizontally disposed lower roller 40 on each side of the coverwhich may be moved toward and awayfrom the cover so that the rollers may be brought into pressing engagement as the folded tabs pass between them and out of pressing engagement as the absorbent cores pass therethrou'gh. After the cover portion between adjacent absorbent cores has been folded and pressed in the manner described, suitable cutting devices, not shown, may be used to sever the folded cover portion between an adjacent pair of absorbent cores to-provide individual napkins.
It is to be understood that the foregoing illustrative embodiment may be varied, modified or altered and still come within the spirit and scope of the inventionand-tha't such changesarecontemplated.
