10 Claims, 5 Drawing Figures 1 CATAMENIAL TAMPON AND WRAPPER THEREFOR BACKGROUND OF THE INVENTION Digital insertion tampons for catamenial use, in which the tampon is enclosed in a dual-purpose protective wrapper, are old in the art. A recent embodiment is shown in U. S. Pat. No. 3,135,262. However, one of the problems encountered in the use of such tampons is that because the tampon body is so small it has been found difficult to handle during the unwrapping process. As a result the tampon often inadvertently slips from the user's grasp and is dropped, whereupon it must be discarded. Also, after the tampon is partially unwrapped preparatory to insertion, difficulties have been encountered in trying to use the wrapper for its intended purpose of protecting the fingers against soilage. The instant invention is designed primarily to overcome these difficulties;

Accordingly it. is the principal object of this invention to provide a digital insertion tampon in which the protective wrapper and tampon body are releasably attached to each other.

Another object is to provide a digital insertion tampon in a convenient easily opened package wherein the wrapper serves as a sanitary and hygienic finger protecting device.

SUMMARY OF THE INVENTION The digital insertion tampon device of this invention comprises a tampon of absorbent material compressed into a selfsustaining, generally cylindrical body with a withdrawal string depending from its lower end and having its upper end tapered and rounded. The tampon is enclosed in a temporary protective wrapper of flexible, fluid-impervious sheet material of beyond the gathered ends. The closure means preferably is a heat scalable tape, or a tape of the cohesive type which sticks only to itself, whereby it will not damage the wrapper upon removal. The wrapper sheet preferably is thermoplastic at least on its inner surface so that it may be attached to the tampon by heat bonding; although other attachment means may be used.

To prepare the tampon for insertion, the wrapped device is grasped at its base by the fingers of one hand and the closure means removed. The comers of the wrapper are then folded back to expose the forward end of the tampon. The withdrawal string is also pulled back along with the wrapper. The tampon is then inserted with one of the fingers while holding onto the wrapper with the others. After the tampon is in place, a gentle tug on the wrapper will separate the wrapper from its weak attachment to the tampon base.

It will be seen that because the tampon is attached to the wrapper sheet, the tampon will not inadvertently fall out or be dropped during the unwrapping procedure as long as one has a grip on the wrapper. The attachment also permits more positive control of the tampon during insertion.

The above and other advantages, objects and features attendant the improved device of this invention will become apparent by reference to the following specification and accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING In the drawing, in which like numbers represent like parts:

FIG. 1 illustrates the relative position of tampon and wrapper before wrapping.

FIG. 2 shows the tampon partially wrapped.

FIG. 3 illustrates the completely wrapped tampon, and also illustrates a means for attaching the wrapper to the base of the tampon by a heat-sealing step.

FIG. 4 is a fragmentary showing of the tampon base illustrating the wrapper in its temporarily fastened relationship to the base.

FIG. 5 illustrates how the partially unwrapped tampon and wrapper may be held preparatory to insertion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 a compressed cylindrical tampon 10 having a conical nose and a withdrawal string 11 attached to its base, is shown disposed on the approximate geometric center of a flexible wrapper sheet 12, of rectangular, preferably square, dimension. In the preferred embodiment, wrapper 12 is a polyethylene tissue laminate in which the top surface 13, in contact with the tampon, is polyethylene film and the bottom surface 14 is tissue.

In FIG. 2, wrapper sheet 12 is shown as it is being gathered and folded upwardly to partially enclose tampon 10. Withdrawal string 11 is folded upward with the wrapper and extends out beyond the ends of the wrapper.

In FIG. 3, the tampon is shown completely enclosed by the wrapper sheet 12, which is gathered together and closed by closure tape 15 immediately above the forward end of the tampon. The tape is of a material which does not stick to the wrapper, and preferably encircles the wrapper with the tape ends stuck together to form a tab.

The assembled tampon and wrapper is pressed against a heated plate 16, or the like, for a time sufficient to soften the interior polyethylene surface andbond it to the tampon base. While this step is shown as taking place after the tampon is entirely wrapped, it will easily be seen that attachment can also be done I when the tampon body is first centered on the wrapper, as in FIG. 1, or after the wrapper is partially folded up around the tampon as in FIG. 2.

FIG. 4 illustrates how the inner polyethylene surface 13 of wrapper 12 is attached to the base of tampon 10 at 17. De- I pending upon the disposition of the withdrawal string, which of course varies from tampon to tampon during the processing steps, the sheet may attach itself in part directly to the string rather than wholly to the tampon base. However, the strength of the attachment bond may be controlled so that the bond is still effective whether attached partly to the string portion or entirely to the base of the tampon body.

In FIG. 5, the partially unwrapped tampon 10 is held in the fingers on the tissue side 14 of the wrapper and is ready for insertion.

After insertion of the tampon, the free ends of the wrapper are grasped and withdrawn, whereby it easily separates from the tampon base without disturbing tampon placement. In order to insure easy separation, the strength of the wrapperto-tampon bond is such that it requires no more than a gram pull to separate. The attachment strength is easily regulated by the dwell time of wrapped tampon on hot plate in the arrangement shown in FIG. 3, as well as by the temperature of the plate itself.

While the preferred wrapper comprises a polyethylene-tissue laminate with the polyethylene disposed on the inside, it

' will readily be seen that the entire wrapper may be comprised of polyethylene film alone, or other thermoplastic films such as polypropylene, polyvinyl chloride, and the like. These also may be in laminated form. The thinner products are, of course, preferred.

The wrapper may also contain thermoplastic fibers for attachment purposes, or be coated with a thermoplastic material on the inner surface.

The compressed tampon body preferably is about one-half to five-eighth inch in diameter at its base and from about 1% to 2% inches long. It is preferably of cylindrical shape with top half tapering to a rounded tip for ease of insertion.

Since the protective wrapper preferably is of a fluid and stain-resistant material the tip of the tampon may also be conveniently coated with a suitable lubricant to aid insertion. A material such as water-soluble surgical gel is useful for this purpose.

A suitable dimension for the wrapper sheet to be used with the above-described tampon is a 6% inches square. A 1 mil polyethylene sheet along, or a 0.5 to 0.75 mil polyethylene sheet laminated to a single ply, 9 lb. drier basis weight, creped cellulose wadding sheet makes a suitable wrapper. The polyethylene may be clear or opaque and may be colored or plain. It may also be embossed to give it an aesthetically more appealing feel and appearance.

A closure tape of the type illustrated is approximately 2 inches long by three-sixteenth inches wide. It is preferred that the tape be of a type which adheres only to itself and not the wrapper. Tape with a cohesive, rather than adhesive, bond coating will serve this purpose, as well as tape which can be heat-sealed or otherwise bonded. Whichever is used, it should be readily frangible, or peelable, so that it can be removed without damaging the wrapper. The tape may be convolutely wound with a loose tab end, or be a single loop with the ends pressed together to form a tab.

Other types of easily removed closures can also be used, including such things as flexible plastic clips, paper or plastic twist tapes with soft metal cores, or rubber bands with finger tabs.

It is understood that the invention is not limited specifically to the preferred embodiments set forth above, and that suitable changes, modifications, and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
