Description
July 2, 1968 G. F. HILDEBRAND TAMPON APPLICATOR Filed Dec. 30, 1965 [NMEA/rc2.
United States Patent O "ice 3,390,671 TAMPON APPLICATOR Gordon F. Hildebrand, St. Charles, Ill., assignor to Purex Corporation, Ltd., Lakewood, Calif., a corporation of California Filed Dec. 30, 1965, Ser. No. 517,662 8 Claims. (Cl. 12S-263) ABSTRACT OF THE DISCLOSURE A tampon applicator providing a self-lubricating surface utilizing a thin coating of a normally essentially dry but water soluble material on the exterior surfaces of the applicator.
This invention has to do generally with improvements in catamenial tampon applicators adapted for vaginal insertion and Ito contain ejectab'le tampons. More particularly the invention relates to lubrication of such applicators to facilitate insertion into body orifices.
Preliminarily it may :be observed that the desirability for providing lubricated applicators arises from the normally relatively dry nature of the vaginal tract which, therefore offers resistance to insertion of the applicato-r.
Heret-ofore it has been proposed to lessen such resistance as by providing applicators with very smooth surfaces, using e.g., smooth plastic materials to form the exposed applicator surface. Also it has been proposed to lend lubricity to the applicator as by waxy (oil soluble) coatings.
Such expendients however do not afford the lubrication desired because they are predicated upon presenting water insoluble surfaces which, however smooth, cannot possess or permit slippage to the degree required for ease and comfort in the use environment.
The present invention departs from such prior proposals in its contemplation lof thinly coating an applicator with a normally essentially dry material which itself has water solubility and therefore, upon becoming moistened, acquires a high degree of slipperiness in and by virtue of at least partial dissolution of dispersion of the coating substance itself, as distinguished from mere surface condition.
The invention has for its general object to provide a tubular tampon applicator with a coating, preferably having continuous uniform thickness, of a material having that degree of water solubility as dispersability in the presence of body cavity moisture, or by virtue of premoistening, that the material becomes inherently slippery and thereby eases the tampon insertion.
While the invention does not contemplate limitation to any particular coating material, useful substances may be selected from the class of organic polymeric materials including the polyvinyl alcohols, polyvinylpyrrolidone, polyethylene oxide, polyglycols, polyether film, alkali metal salts of polyacrylic acid, alkali metal salts of alginic acid, polysaccharides such as modified starch, sodium carboxymethyl celluloses and hydroxyethyl celluloses. Of these polymers, polyvinyl yalcohol may be regarded as typical.
Generally the degree of water solubility of such materials may be deepndent upon their degrees of polymerization, solubility decreasing with increasing polymerization. For purposes of the present invention, intermediate polymerization is desirable so that the coating will not tend to have undue moisture acceptiveness as by exposure to normal humid atmosphere, but will at least partially dissolve or disperse upon aqueous liquid contact. Whether in a strict technical sense these polymers undergo apparent dissolution by formation of true aqueous 3,390,671 Patented July 2, 1968 solution, or aqueous dispersion, the change in state herein will be referred to as one of solution.
The various features and objects of the invention will be more fully understood from the following detailed description of illustrative embodiments shown lby the accompanying drawing, in which:
FIG. 1 is a view partly in section showing an illustrative tampon and its applicator assembly;
FIG. 2 is an enlarged elevation yalso partly in section, showing the coated section `of the applicator tube;
FIG. 3 is an enlarged cross section on line 3--3` of FIG. 2; and
FIG. 4 is a view illustrating a variational embodiment of the invention.
Referring rst to FIG. l, the assembly in its generalities is shown to comprise a usual combination of a tampon 10 which may be of any suitable specific form and composition, contained within an applicator tube 11 which receives within its open end opposite the tampon a slideable ejector 12. The usual string 13 connected to the tampon, extends through the ejector 12 so as to fbe retained by the tampon after its projection from the applicator.
In more particular reference to FIG. 2, the applicator 11 is shown to comprise an open end coated tube, the inside or base 14 of which maybe formed of any suitable or usual material, such as single or multiple layer paper. The invention is more particularly concerned with the provision on the exposed applicator surface of a coating or layer 15 of the previously described moisture soluble lubricant. Preferably, in the interests of assuring uniformity of the coating thickness and continuity, and for efiicient manufacture, the tube 1-4 is wrapped spirally or otherwise, with relatively thin paper 16, the surface of which is coated by known paper finishing methods with the polymer 15 at a thickness of between about 1/2 to 11/2 mils.
While use of a polymer coated paper wrap about the tube is preferred for the reasons stated, it is also possible to coat the tube 14 directly at some sacrifice of thickness uniformity, as by spraying or otherwise depositing the polymer onto the tube surface. Thus in FIG. 4, a solution of the polymer is shown to be deposited from a spray 17, the deposited film being dried in any suitable manner.
Upon being contacted by moisture, the polymer coating 14 undergoes at least partial solution or dispersion so that within itself, as distinguished from mere surface effect, the coating acquires a flowability or shearability which results in inherent lslipperiness affording the ideal qualities for non-irritating lubrication.
I claim:
1. A catamenial tampon and applicator therefor adapted for vaginal insertion comprising an ejectable tampon and an applicator comprising a tube having an outer surface coating of a thin Water soluble polymer which becomes slippery upon and by virtue of vaginal moistening.
2. Applicator according to claim 1, in which the thickness of said coating is between about 1/2 and 11/2 mils.
3. Applicator according to claim 1, in which said coating .is a preformed film of uniform thickness.
4. Applicator according to claim 1, in which said tube includes a tubular body having a wrapper whose outer surface is filmed with said coating.
5. Applicator according to claim 1, in which said body is a paper tube and said wrapper is carrying said paper coating.
6. Applicator according to claim 1, in which said tube comprises a tubular body covered by a wrapper having a water soluble organic polymer outer surface coating of thickness between about 1/2 and l mil.
3 4 7. Applicator according to claim 6, in which said References Cited coating is carried on paper wrapped yaround said tube. UNITED STATES PATENTS 8. Applicator according to claim 1 in which said coatalkali metal salts yof polyacrylic acids, alkali metal salts -of alginic acid, and polysaccharides selected from starch, carboxymethyl celluloses and hydroxyethyl celluloses.
