  • catamenial tampon applicator which has been in use for many years consists of telescoping tubes wherein the outer tube carries the tampon in one end portion thereof and an inner tube frictionally fits in the other end positioned to abut the inner end of the tampon to project out from said other end of the outer tube.
  • This applicator has performed well. For example, in order frictionally to maintain proper assembled relationship between the inner and outer tubes during delivery to the ultimate user, very close manufacturing tolerances have had to be maintained between the inside diameter of the outer tube and the outer diameter of the inner tube.
  • the outer tube of the applicator near its rearward end (opposite from the end adapted to receivev the tampon) has a series of relatively closely spaced circumferential grooves which form inwardly directed ridges on the interior having shallow valleys there between, said ridges preferably having substantially identical diameters in order to hold an inner ejector tube concentrically therein.
  • Said inner tube advantageously has two opposing nib projections, formed thereon by outwardly directed pressure, with sufficient height to press in engagement into the valleys formed between said ridges and being positioned longitudinally at a point such that the nibs fall approximately in the middle of said series of ridges when the front end of the inner tube abuts the tampon positioned in the outer tube.
  • FIG. 1 is a side elevation of a preferred embodiment of the present invention.
  • FIG. 2 is an enlarged detail view of the device in FIG. 1, shown partially in section.
  • FIG. 3 is a view similar to FIG. 2 of a modified preferred embodiment.
  • the applicator tube 10 is formed of an outer carrier tube 12 and an inner ejector (or plunger) tube 14.
  • These tubes 12 and 14 are typically made of thin strips of paper spirally wound, with successive layers overlapping to reinforce one another. Each layer is cemented to the adjacent layers by an adhesive which is readily water soluble. Thus, after the tube has served its purpose, it can be discarded into a toilet bowl loosening the adhesive and delaminating the tubes into thin paper strips which can be readily flushed through the plumbing.
  • FIG. 1 shows the assembled tampon l5 and applicator 10 ready for use.
  • the front end of the compressed catamenial tampon 15 can be seen at the right of FIG. 1 (extending from the carrier tube 12).
  • the rear end of the same tampon 15 can be seen in FIG. 2 within the carrier tube 12 abutting the front end of the ejector tube 14.
  • the tampon 15 can be made according to the standard practice in the art but advantageously is formed by compression of a pad made of transversely laid long staple cotton fibers sewn down the middle with a chain of stitches trailing therefrom to form the withdrawal string 16.
  • a pad with its withdrawal string is described and illustrated in a patent issued to my coworkers as U.S. Pat. No. 3,322,123, issued May 30,
  • the surface layer of the tubes 12 and 14 advantageously may be covered with a thin coat of a slick material usually in the form of a solid lubricant which facilitates the insertion of the applicator into the vaginal cavity without discomfort.
  • a slick material usually in the form of a solid lubricant which facilitates the insertion of the applicator into the vaginal cavity without discomfort.
  • This may be formed of polyethylene oxide or other waxy material.
  • the tubes 12 and 14 commonly are about three inches long.
  • the outer tube 12, in the example illustrated in FIG. 2, has seven annular external rings 17 formed by eight grooves 18 and eight internal ridges 22. These numbers have been found most advantageous when the tube is of wound thin paper strip,
  • Such paper may typically be 0.015 inch thick.
  • five to 12 grooves in a width (measured longitudinally of the tube) about three-eighths inch to three-quarters inch can be used and may have a depth of about 0.01 inch and a pitch of about 0.07 inch.
  • the ridges 22 at the peaks give an inside diameter less, by 0.005 to 0.025, inch than the inside diameter of the adjacent smooth tube beyond the rings. We find that a diameter 0.015 inch less than the adjacent undeformed tube is preferable, giving substantial frictional engagement between the tubes without producing excessive resistance to ejection of the tampon.
  • the grooves 18 may be formed relative to ridges 22 as in FIG. 2 to assist in the formation of said ridges 22, or may be formed as in FIG. 3 to give more strength to thetube 12 by avoiding abrupt edges when using certain materials.
  • the ridges 22 are rounded, in stead of being more sharply peaked.
  • This grooving 18 in addition to providing a finger grip enhancement also serves to coact with raised nibs 20 to form an effective tube lock.
  • the inward height of the ridges 22 and the depth of the valleys 24 are such as to give a uniform detention with the nibs 20.
  • the approximate uniformity in height of the projection v22 gives multiple rings of support of approximately the same diameter without substantial clearance between the telescoped tubes 12 and 14.
  • the end 19'of the outer tube 12 may be curled inwardly to the same diameter (as shown in FIG. 2).
  • the radius of curvature in successive grooves is advantageously such that the diameter of the tubing 12 measured to the rings 17 of opposite valleys 24 is a very little less than, or even the same as, the diameter of the undeformed tubing 12 beyond the grooving 18.
  • This uniformity and positive formation of the valleys 24 assures maximum effectiveness of the interlock with minimum deformation of the tube walls by the grooving 18.
  • the tube 14 has nibs 20 formed on its outer surface with convex curvature closely approximating the concave curvature of the valleys 24.
  • the height of nib 20 is 0.01 inches above the outer diameter of the tube 14.
  • it is preferable to give a more balanced and effective interlock by having at least two opposing nibs equally spaced circumferentially about tube 14.
  • the pitch of the grooves i.e., the distance between the summits or nadirs of adjacent grooves
  • the pitch of the grooves could be substantially greater than the corresponding dimension of the nibs 20 this would still give a true interlock when two or more arealso longitudinally spaces so as to trap immediately therebetween one or more projections-22 so as to avoid longitudinal play.
  • two such nibs in two different valleys would be positioned relative to their respective projections so as to have no such play.
  • each of diametrically opposed nibs 20 forms a raised projection on the outer surface of the ejectortube 14 which subtends an angle of approximately circumferentially.
  • the grooving 18 has been interrupted in fanciful design, here to reproduce the. outline of Trademark Registration No. 585,933. With such discontinuity of the grooving 18, it is desirable to have the nibs 20 circumferentially long enough to bridge such gaps and to give effective interlocking even in-the area of such discontinuity. Note that at such discontinuities, there being no grooving 18, there usually is consequently no corresponding projections 22 on the interior of the tube 12.
  • the grooves 18 of the present invention represent a total departure from all prior art finger-grip concepts, which, typically, involved raised external projections of various types.
  • the present invention permits the combination of the finger-grip feature with an effective tube interlock, where latter has the singular advantage of being self-healing if displaced.
  • tube interlock In most previous tube interlocks a portion of one interfitted tube is displaced into the other in a one-on-one relationship. Upon displacement, such one-on-one relationships are destroyed, and usually could not effectively be reestablished.
  • a nib 20 can engage a second or third valley 22 after it has been displace. Mere frictional interlocks were found to be substantially inferior.
  • the two nibs 20 externally raised on opposite sides of the internal tube 14 not only give an effective interlock, but also permits a relaxation of manufacturing dimensional tolerances of the tubes and further creates a continuously positive tube lock.
  • These nibs are advantageously located on the ejector tube 14 in an end zone one-eighth to three-fourths inch from the end of the tube. In the preferred example above described they are one-half inch from the end.
  • the nibs shown in the preferred embodiment extend over 90 around the circumference of this tube but any extent from 50l 20 can be used with satisfaction.
  • the over-all diameter of the tube 14 on opposite sides is increased by about 0.005 to 0.03 inch when the nibs are included. In the preferred example we have found an increase of 0.02 inch best. These diameters are taken from the apogee of the nib on one side to the corresponding point on the opposite nib and this distance is compared with a corresponding measurement of a part of the tube where there are no projections or other deformation.
  • the present invention rather than hindering delamination when discarded, tends to facilitate it.
  • the applicator tubes may be made of other sheet material instead of paper, e.g., plastic, or the tubes may be molded of plastic with the ridges and grooves. Instead of rolling the grooves, ridges and nibs, etc., into the wall of the tubes, they may be molded into it by pressing it in a mold either with or without heat.
  • a tampon applicator comprising an outer tube adapted to contain a tampon in the forward end thereof, an inner tampon-ejecting tube fitted within said outer tube, said outer tube having in the rearward portion thereof a series of at least four adjacent substantially circumferential internal ridges with at least three shallow, equally-sized, valleys alternating therebetween and with similarly positioned grooves formed externally in a finger-grip pattern, said inner tube having at least one raised nib being of substantially the same longitudinal curvature and size of said valleys in order to frictionally interlock within any one of said valleys to inhibit relative longitudinal movement of said applicator tubes and being of a transverse circumferential extent of less than a total of 240, the outer diameter of said inner tube being sufficiently smaller than the inner diameter of said outer tube so as to form a loose fit therebetween, said internal ridges all having the same minimum inside diameter which is approximately the same as the outside diameter of said inner tube whereby to give a snug fit between said tubes with a controlled range of expulsion pressure.
  • grooves and ridges are each eight in number and are formed in anapproximately one-half inch axial extent with groove depths, ridge and nib heights of approxi-- mately 0.01 inches.
