Abstract

A reusable tampon comprising downwardly inclined inflow apertures (3) for passage of menstrual blood to a closed depositing space (8).

Description

A SAFETY TAMPON
The present invention relates to a hollow tampon manufac¬ tured from hygienic and tissue-friendly flexible material, with which the user herself fills the tampon with absorbent material which is then discarded after use, whereafter the tampon is refilled with absorbent material by the user for further use. In other words, the safety tampon is reusable.
The amount of menstrual fluid discharged from women will vary from person to person. The safety tampon provides women with the possibility of modifying their own need for absorbent material during their menstruation periods.
As a result of its design, the design of the safety tampon eliminates saturation and also the dripping effect of tampons - soiling of clothes and possibly also furniture. The inventive tampon is therefore called a safety tampon, since it affords a degree of safety or security to the wearer.
It is generally known that tampons commercially available at present are liable to injure the extremely sensitive and easily irritated walls of the vagina of the female wearer to a greater or lesser extent. Furthermore, the microscopic injuries caused to the mucous membrane and to the walls of the vagina of women who use tampons render these parts of the body extremely receptive to infectious diseases of diverse kinds.
These dangers and related dangers and discomfort are eliminated by the present invention as a result of the following properties.
1) The tampon is counteractive to tampon saturation and droplet effect. 2) The design of the safety tampon and the tissue-friendly material from which it is made eliminates the hazard of injury to the vagina of the female wearer.
The invention thus relates to a hollow tampon which is made of flexible, tissue-friendly material and which includes on the outside of the tampon a plurality of downwardly inclined so-called inflow apertures through which menstrual fluid is able to pass to a closed space located in the lowermost part of the tampon. The user has earlier placed in this space, or cavity, an absorbent material - a highly absorbent material - as necessary. In other words, the user herself fills and refills the tampon with absorbent material and discards this material after use, and then refills the same tampon with absorbent material to obtain an effective tampon. This procedure enables the safety tampon to be reused over a long period of time.
The invention will now be described in more detail with reference to an exemplifying embodiment thereof and also with reference to the accompanying drawing, in which
Fig. 1 is a schematic longitudinal section view of one exemplifying embodiment of an inventive tampon;
Fig. 2 illustrates schematically solely the axially extending flow grooves which facilitate the flow of menstrual fluid to the so-called inflow apertures, from which the fluid then passes to the closed space in the lowermost part of the tampon; and
Fig. 3 is a longitudinal, schematic section view of
"radial pits or recesses" whose function is to facilitate placement of the tampon in a fixed position in the vagina. This longitudinal section view also shows the downwardly inclined, so-called inflow apertures, and also a ball of highly absorbent material in the closed space in the lowermost part of the tampon.
The tampon can be said to have an elliptical shape formed by tissue-friendly, flexible material over whose upper part there has been inserted an oval profile and an elliptical opening. The lower part of the tampon is closed in a semi¬ circular shape.
Fig. 1. The reference numeral 1 identifies an opening in the upper part of the tampon which allows menstrual blood to pass to the closed space in the lowermost part of the tampon. The opening is also used by the wearer to remove used absorbent material and also to insert new unused absorbent material.
The reference numeral 2 identifies the outside of the tampon.
The reference numeral 3 identifies the plurality of so- called downwardly-inclined inflow apertures on the outside of the tampon. In order to obtain a maximum receptive effect, the so-called downwardly-inclined inflow apertures 3 have been placed as shown in Fig. 1 (a schematic longitu- dinal section view).
The reference 4 identifies an appendage connected to the lower, closed semi-circular part of the tampon. The appendage is used to facilitate removal of the tampon from the vagina of the female wearer.
Fig. 2. The reference numeral 5 identifies the axially extending, so-called inflow grooves which facilitate flow of menstrual blood to the so-called downwardly-inclined inflow apertures 3, from where the blood passes to the closed space in the lowermost part of the tampon. The so- called inflow grooves 5 depart from the upper part of the tampon and extend to the so-called downwardly-inclined inflow apertures 3 located lowermost in the tampon.
Fig. 3. The reference numeral 6 identifies "radial pits or recesses" provided on the outside of the tampon, these pits functioning to facilitate fixed positioning of the tampon in the vagina.
The reference numeral 3 identifies the plurality of so- called downwardly-inclined inflow apertures on the outside of the tampon which, when the tampon is inserted in position in the vagina of the wearer, permits menstrual blood to pass to the lower part of the tampon and therewith to its closed space. In order to obtain a maximum receptive effect, the so-called downwardly-inclined inflow apertures are placed in the positions shown in the schematic longitu¬ dinal section view of Figs. 1 and 3.
The reference numeral 4 identifies a ball of highly absorbent material which is located in the closed space in the lower part of the tampon.
When the user so desires, she replaces the consumed, wet material with new, unused absorbent material in the closed space of the tampon, precisely as she herself desires.
The reference numeral 8 identifies the so-called depositing space.
It is thought that the manner in which the inventive safety tampon works will be understood in all essentials from the aforegoing. As a result of its design, the safety tampon eliminates the saturation and dripping effect of tampons - soiling of clothes and possibly also furniture. The invention enables women to adapt conveniently the consump¬ tion of "absorbent material" during a menstruation period, in accordance with her own requirements. The safety tampon can be reused over a long period of time, which means that the safety tampon is economically rewarding to the user.

Claims

1. A tampon, characterized in that it is hollow and is preferably comprised of flexible, tissue-friendly material; in that the lower part of the tampon is closed, preferably in a serai-circular shape, and is configured to form a depositing space (8), a storage space, for inflowing menstrual blood.
2. A tampon according to Claim 1, characterized by downwardly-inclined, inflow apertures (3) provided on the outside of the tampon, the function of said apertures being to permit menstrual blood to pass to the depositing space (8) of the tampon.
3. A tampon according to Claim 1 or 2, characterized by axially extending inflow grooves (5) provided on the outside of the tampon for facilitating the flow of menstru¬ al blood to the downwardly-inclined inflow apertures (3), whereafter the blood passes to the depositing space (8). The inflow grooves (5) extend from the upper part of the tampon and continue axially along the outside thereof but terminate at the downwardly-inclined inflow apertures (3) located lowermost in the tampon.
4. A tampon according to Claim 1, 2 or 3, characterized by small balls of highly absorbent material which enable the user to vary the absorbency of the tampon.
5, A tampon according to Claim 1, 2, 3 or 4, characterized in that it has the form of an elliptical cylinder, Fig. 1, Fig. 2, Fig. 3.
6. A tampon according to Claim 1, 2, 3, 4 or 5, character- ized in that the tampon has the form of a straight cylin¬ der.
7. A tampon according to any one of the preceding Claims, characterized in that the tampon cavity can be filled with absorbent material in accordance with the wishes of the user, therewith rendering the tampon reusable.
