Description

FIELD OF THE_INVENTIO~
The subject invention relates to a cardboard tube particularly useful for the insertion of a tampon and a process for making the same.
Tampons conventionally sold in the United States employ means for insertion of the tampon pledge into the user's vagina These means generally are in two pats with the outer part being a tube with an inner diameter slightly greater than the outer diameter of the tampon pledge. The second part of a tampon inserter means is some time of plunger which operates in cooperation with the tube to expel the pledge. The tubes are generally made of paper products such as cardboard or thermoplastic. Further, thermoplastic tubes generally have an insertion end which forms a hemispherical profile around the leading edge of the tampon to protect it and maintain its integrity during insertion. Commercially available tampons utilizing cardboard tubes, however, generally do not have this type of closure, but rather the leading edge of the tampon extends beyond the tube end. Both thermoplastic and paper derived tubes can be made with a reduced diameter base which can be used for gripping or to better maintain the plunger used or expulsion r OX for both purposes.
The ideal tampon tube should be inexpensive, simple to make, easily disposable, attractive and hygienic. Both I.
SLY
molded plastic and paper inserter tubes have not been completely satisfactory in meeting these desirable attributes.
Tubes which axe molded from the thermoplastics are neither water dispersible or flush able Furthermore, the relative cost of thermoplastic is substantially greater than tubes which are made from paper or paper products. In addition, thermoplastic molded tubes having a hemispherical shaped leading edge comprising individual arcuate shaped lobes are extremely difficult to mold without providing lobes having sharp edges or flashing, i.e., irregularly shaped burrs of plastic. Such tubes could provide problems when being withdrawn from the vagina. Paper tubes, on the other hand, also have problems. Commercially available cardboard tubes for tampons are generally spirally wound and open at the leading edge which may result in a fiber slough when the tampon is inserted. The only known paper tubes with shaped tips are spirally wound with the shaping of the tips being accomplished by crushing, deforming and pleating the formed tube, or alternatively, by cutting triangular shaped petals in a preformed tube. Both of these methods for forming a tube which covers the insertion edge of the pledge are complex and in the case of crushing, deforming and pleating, expulsion of the tampon is extremely difficult. If a paper based tampon tube having a plurality or arcuate lobes with a hemispherical profile is desired, and the tubes are cut from a flat tampon blank, spiral winding will produce "ghosting", i.e., an aye overlap of the individual lobe segments due to the spiral winding. Attempts to produce such a leading edge with a spirally wound tube, therefore, are best performed after the tube is formed which is substantially more difficult. As can be seen from the previous discussion, while a paper based tarpon tube with a hemispherical leading edge to cover the tampon is highly desirable from the standpoint of material cost and disposability, the difficulties in forming such a tube have inhibited their practical application. The tampon tube of this invention, by employing convolute winding and a thermoplastic coating, overcomes many of the difficulties associated with paper-based tampon tube manufacture.
One aspect of the invention resides in a con-volatile wound flexible paper tampon tube with an insertion end and a gripping end, wherein the insertion end includes a plurality of non overlapping arcuate lobes forming a hemispheric profile, the lobes being scored near their base. The tube has at least one thermal sensitive coating in an amount sufficient to provide shape retention without the addition of a separate adhesive.
According to another aspect of the present invention, there its provided a process for manufacturing a convolutely wound paper tampon tube with non overlapping arcuate lobes.
the process includes the steps of die cutting a flat blank for the tampon tube having a plurality of arcuate lobes positioned along a top edge portion of the blank and scoring the blank at a bottom end portion thereof. At least one side of the tampon tube is coated with a sufficient thermosensitive coating to heat set the tube after forming. The arcuate lobes are scored B my 1 -I
~Lff~i~76~
near their base, and the tampon tube is convolutely wound. The bottom end is compressed to form a reduced diameter gripping portion and a tampon pledge is inserted through the top portion leaving slightly less outside diameter than the inside diameter of the tampon tube, the leading edge of the tampon pledge extending at least partly into the area containing the arcuate lobes. The plurality of lobes is shaped in a hemispherical configuration, and the thermosensitive coating is heat set.
In a specific embodiment of the invention, there lo is employed a water soluble or water dispersible thermoplastic binder which would aid in disposal of the applicator. If such a composition was used as the only thermoplastic binder material the applicator can be rendered flush able in conventional toilet systems. Coatings of different thermoplastics for the same applicator are also contemplated within the scope of this invention, and specific combinations of thermoplastics may be utilized for specific properties, e.g. surface finish, flush-ability, etc.
Suitable water dispersible and water soluble thermos plastic coatings are: polyethylene oxide, polyvinyl alcohol, polyvinyl acetate, polyvinyl pyrrolidone, and hydroxypropyl cellulose.
The concept of convolute winding is well known.

DETAILED DESCRIPTION OF THE INVENTION
The invention may more readily be understood by reference to the drawings in which:
FIG. 1 is a plan view of the flat blank for the tampon tube of -this invention;
FIG. 2 is an end view of the tampon tube with the tampon inserted; and FIG. 3 is an end view of the tampon tube with the hemispherical forward end being formed.
As can be seen in FIG. 1, a blank useful for making the tampon tube of this invention is formed by precutting the arcuate lobes 10 so that when the tampon tube is formed as - pa -mob/ Ye Jo 7~i~2 shown in FIG 2, the lobe configuration is already present at the leading or insertion edge These lobes may be formed for example by die cutting To provide increased flexibility, score lines 11 are preferably added during the forming process. The blank 1 also has score lines 14 present near the portion which will ultimately result in the necked in gripping area at the bottom of the tube. The score lines define a slightly recessed area 12 which can be wormed my embossing.
When the blank is rolled to form the tube as can be seen in FIG. 2 the surface of the compressed area 13 forms a sight of reduced diameter for positioning and gripping prior to insertion.
The blank may be made by laying several sheets o' paper and attaching them by means of a heat wettable adhesive or by a thermoplastic coating or, alternatively, it may be by .. .. ..
a single thickened sheet of paper or cardboard or the like An outer surface of the blank can ye coated or a coated paper may be used to provide the heat sensitive coating which is used for shape retention in the subject invention.
I The coating may be a polymer coating such as any of the common thermosensitive oiliness like polypropylene or polyethylene or the coating may be in the form of a heat-activata~le adhesive composition. The critical parameter for the coating is that it is plowable at temperatures below the charring or combustion temperature of paper and the melting point of common polyolefins are well known with the specific ` ~2~7~
compositions useful in the practice of this invention not being part of the subject matter thereof.
The tampon tube it then formed as indicated in FIG.
2 and the coating activated by suitable heating means which may be dielectric, microwave, typical convection heating or to like. The heating source is withdrawn, the coating is set and the tube is formed with the coating as the means for maintaining its configuration. As can be seen in FIG. 2, partially in phantom lines, the tampon T is positioned within the tube and loaded from the leading edge. It is possible to load the tampon from the bottom if there is no reduced diameter gripping portion: The tampon may be inserted prior to heat setting or during heat setting depending upon the particular heat setting treatment desired. If heat setting is used which will not damage the surface of the pledge, it may be more convenient to insert the pledge prior to the heat activation and subsequent setting of the tube. This is particularly true because it would allow a single heating step for the setting of the tube configuration as well as the foxing and positioning of the arcuate lobes about the leading edge of the tampon as will be discussed in more detail below.
The degree of winding will vary to some extent depending upon the thickness of the tube desired which is, of course, dependent upon top thickness of the blank. Another variable to take into account is the flexibility of the paper ~1766~
component after coating has been added because it is desirable that the tampon tube provide a smooth wrinkle free surface.
By convolutely winding the arcuate lobes which will be eventually shaped in a hemispherical configuration can be positioned so thaw there is virtually no "ghosting". The perfect alignment of the convolutely wound lobes minimizes the potential for injury due to the overlap of thy lobes between layers of paper.
The necked in portion can be formed at the bottom of the tube at the same time thy tube is formed because of the compression associated with the axes 12 and 14 at the tube blank. When the slightly recessed area 12 and the scored lines 14 are foxed in the manner depicted they can be easily compressed as the tube itself is convolutely wound.
As shown in FIG. 3, once the tampon is inserted, the lobes are inwardly bent against the hemispherical leading edge of the tampon and heat set. If heat swept of the tube forming step and the arcuate leading edge can be performed in the same operation, a substantial amount of energy and process time will be saved and this is indeed the preferred embodiment. There may be instances, however, when due to the choice of materials for the tampon itself or the paper this approach is undesirable.
As can also be seen from FIG. 3, a rod 15 which is preferably hollow extends into the interior portion of the tube and is designed to nest against the tampon T. When 2~L7~2 pressure is exerted against the rod 15, the tampon is dislodged and properly inserted. The score lines 11 help to increase the flexibility of the lobes 10 making the pressure required for such insertion minimal.
