Abstract

The present invention relates to a tampon suitable for feminine hygiene and having a horizontally elongated body made from a compressed absorbent fibrous material with an insertion end and a withdrawal end, and a string for removing the tampon, which is secured by one end in the body of the tampon. The tampon has a truncated conical shape with a sloping base and at least one transverse groove configured in a circle on the surface of the tampon, and further has a string situated at an angle in the body of the tampon, said string protruding from the elongated side at the edge of the surface of the withdrawal end which is at an angle to the axis of the tampon. The transverse groove is configured with and without raised elements in the form of ridges and letters. The proposed tampon design in the shape of a truncated cone with an angled base (a sloping withdrawal end) and a transverse groove(s) passing across the surface of the tampon, as well as an inclined string and a domed insertion end simplifies the processes of insertion and removal, protects against drying of the vaginal walls, a side effect inherent in all previously known tampons, and also prevents accidental passage of the tampon from the vagina into the uterus.

TAMPON Technical Field of the Invention

The present invention relates to hygiene products intended for insertion into a human body cavity, in particular to tampons suitable for feminine hygiene, for example menstrual.

BACKGROUND OF THE INVENTION

Intravaginal tampons are widely used by women to retain body fluids that drain along the walls of the vagina during the menstrual cycle. Intravaginal tampons are usually made from absorbent materials, such as cotton, viscose rayon cotton wool, synthetic sponge, cellulose fluff, synthetic fibers, or combinations of these materials, by compressing or shaping to give them an almost cylindrical shape and size suitable for placement in the vaginal tract.

Tampons with an inlet end, an outlet end, an extraction cord and a central portion — a body extending between them are well known. Cylindrical tampons with ribs limited by grooves are also known, said ribs extending radially outside the tampon. Such tampons are known, for example, from WO 2002/078586, EP 0422660, US 2002/0157222, US 5592725, US 5895408, EP 1 108408, US 2003/0208180, WO 2000/53141 and EP 0639363.

In addition, tampons with grooves extending in the longitudinal direction of the tampon are known. For example, WO 2002/078586 and WO 2002/076357 describe tampons with spiral grooves. The outer surface of the tampons is provided with spiral pressed longitudinal grooves extending in a straight line in the longitudinal direction of the tampon. However, such tampons have the disadvantage of their cylindrical shape and the presence of various kinds of longitudinal straight and / or spiral grooves. Such tampons, as a rule, are characterized by insufficient volume and slow absorption, and their shape leads to drying out of the vaginal walls.

Despite the presence of a wide variety of feminine hygiene products on the market, manufacturers of such products continue to search for more comfortable, convenient swabs with increased absorbency, the production of which can be simpler and easier and less costly.

SUMMARY OF THE INVENTION

The present invention relates to a feminine hygiene tampon comprising a longitudinally elongated body of compressed absorbent fibrous material with inlet and outlet ends and a tampon extraction cord fixed at one end in the tampon body, in which the tampon body has a truncated conical shape with a beveled base, on the surface of which at least one transverse groove is made in a circle, and the cord is placed in the body of the tampon at an angle to the axis of the tampon and comes out from the elongated side at the edge of the surface and an output end made at an angle to the axis of the tampon.

The proposed configuration of the tampon in the form of a truncated cone with a base made obliquely to the axis of the tampon, and a transverse groove extending over the surface of the tampon, as well as with a dome-shaped inlet end and an inclined cord placed therein, simplifies the procedure of its insertion and removal, and most importantly prevents the wall from drying out vagina, which as a side effect is inherent in all previously known tampons.

In addition, the expanded outlet end has a diameter larger than the diameter of the inlet end, which prevents accidental passage of the tampon from the vagina into the uterus, as is sometimes the case when using cylindrical tampons. The proposed shape of the swab in the form of a truncated cone is more convenient to use.

The proposed tampon, in particular, is characterized in that the grooves can be one or more, they are located across the longitudinal axis of the tampon and are made in a continuous straight line. The specified groove or grooves can be located both in the upper part of the body of the tampon, and in any other part between the input and output ends of the tampon.

The proposed tampon, in particular, is also characterized in that at least one semicircular protrusion extending along the entire groove can be made in the transverse groove, or longitudinal convex rectangular narrow protrusions, various convex letters or combinations thereof can be made. These protrusions and letters can be made with an angle of inclination to the horizontal axis X, ranging from 45 to 135 degrees.

The proposed configuration of tampons with an annular transverse groove and / or grooves extending along the outer surface of the conical shape of the tampon with a beveled base gives the proposed tampon several important advantages over previously known tampons, in which the grooves are located along the axis of the tampon or are curved in the longitudinal direction, as in tampons with spiral grooves. The transverse groove with and without the above convex elements in the proposed tampons, significantly improves the absorbency of the tampons and prevents the walls of the vagina from drying out. The location of the grooves in the proposed swab in the transverse direction, thus, provides a much greater expansion and absorbency of the swab compared to swabs with spiral or longitudinal grooves.

Also, the expansion of the tampon at the output end prevents accidental passage of the tampon from the vagina into the uterus, which is possible when using cylindrical tampons. The proposed conical shape of the tampon is more convenient to use.

According to the invention, a recess for the finger, which has a concave domed shape, can be made on the tapered surface of the output end of the tampon. The recess facilitates the handling of the swab and its introduction.

On the technical side, the manufacture of the proposed tampons does not have the problems inherent in tampons with longitudinal grooves, where after pressing the tampons with spiral or longitudinal grooves cannot be removed from the pressing device without the influence of significant friction arising between the equipment and products, which can at least , partially destroy the formed grooves. The present invention provides tampons with an improved configuration that allows for easier and more efficient production of tampons. In particular, due to the special configuration of the tampon during the manufacturing process and, more precisely, during removal of the tampon from the pressing device, the transverse grooves are not destroyed, as this occurs with grooves of a longitudinal, spiral type. Advantageously, the tampon manufacturing process is thus more efficient in terms of production time and significant reduction in material loss.

DETAILED DESCRIPTION OF THE INVENTION

The configuration and advantages of the proposed swabs are given below with reference to the accompanying drawings.

The present invention relates to a tampon 1 suitable for feminine hygiene, having a longitudinal body 2 of an almost annular truncated conical shape with an input end 3 and an output end 4 (FIGS. 1 and 2) and a cord 5 for removing the tampon. The cord 5 for removing the tampon is placed in the body of the tampon at an angle to its axis and exits through the outlet end of the tampon from the edge of the base surface, which is at an acute angle to the wall of the tampon, which facilitates the extraction of the tampon. As shown in FIG. 1 and 2, the tampon 1 mainly consists of a compressed absorbent fibrous material and has an outer annular, conical surface on which at least one transverse groove 6 and a concave recess for the finger 7 are made.

As shown in FIG. 5 and FIG. 6, at least one semicircular protrusion extending along the entire groove can be made in the groove 56, 66. The number of protrusions in the form of a semicircle can be from 1 to 5.

As shown in FIG. 7 and FIG. 8, longitudinal convex rectangular narrow protrusions or various convex letters may be formed at the bottom of the groove 76, 86. FIG. 9 shows a sectional groove profile in which convex elements can be made: longitudinal convex rectangular narrow protrusions or various convex letters 96 ¹ (Fig. 7-8) or convex semicircle 96 ^{; /} (Fig. 5), and a rectangular profile of the groove in the section without convex elements 9B "(Fig. 1-3).

The specified longitudinal convex rectangular narrow protrusions or letters in the groove in the groove, can be performed both individually and in various combinations of protrusions and letters.

Also, the protrusions and letters can be made with an angle of inclination to the X axis in the range from 45 to 135 degrees.

In particular, the invention is characterized in that the annular groove of the tampon extending across the longitudinal axis of the tampon has a depth and width preferably in the range of 0.5 to 4 mm.

The number of transverse grooves may vary, for example, depending on the diameter of the tampon and / or on the type of absorbent material. Preferably, the number of grooves is 1 or 2.

The groove or grooves can be made both in the upper part of the tampon body and in any other part between the input and output ends of the tampon.

In addition, the tampon is equipped with a rounded domed inlet end of high compression. This facilitates the insertion of the tampon, since the narrowed end is more convenient to enter and easier to enter the vagina.

In a compressed state, the tampon has a length L in the axial direction of the tampon body and a width W in the transverse direction of the tampon body (Fig. 2). The term “swab length” refers to the length of the swab body in the direction of the Y axis. The term “swab width” refers to the width of the swab body in a compressed state in the direction of the X axis.

In a preferred embodiment, the invention provides a tampon, in which the output end is provided with a recess for the finger, made in accordance with any known technology that allows you to create a concave conical shape.

In another preferred embodiment, the invention provides a tampon, in which the output end is provided with a recess for the finger and has a concave domed shape.

Providing a recess to the output end of the tampon facilitates handling and administration of the tampon. The proposed swab is additionally placed in a packaging shell with a marking that includes coloring in one or more colors to indicate size or absorbency.

Any of the tampon options described above is made by squeezing the fibrous material with the press jaws, on which a groove print is applied (cut) without internal protrusions or with the necessary pattern (print) inside the groove (negative).

Use the proposed swab during menstruation should be as follows.

After washing your hands thoroughly, remove the packaging shell from the swab 1 and take it by the output end 4 in the place where the cord 5 is fixed, and insert the swab into the vagina. In the case of using a tampon 1 with a concave recess for the finger 7, the tampon 1 is taken in hands, as shown in FIG. 4, and injected into the body cavity.

The tampon 1 has a domed inlet end 3 and is made of a compressed absorbent fibrous material, so it easily enters the opening of the vagina and tightly closes it.

After the liquid has impregnated the entire tampon 1, it is removed by the cord 5. When removed, the tampon 1 assumes the position shown schematically in FIG. 3.

Real swabs provide several important benefits.

• Tampons containing a transverse (transverse) groove (s) having a specific location are easier, faster and more economical to produce. The manufacture of a tampon according to the invention is possible using tools (press jaws) that are capable of compressing the fibrous material of the tampon blank.

· Tampons with grooves located transversely to the longitudinal axis have a high absorbency and an increased expansion rate.

• The tampon has good elasticity (expansion) properties and provides increased tightness, since the lower (output) part of the tampon has a larger diameter, and the transverse groove and / or grooves placed in a circle on the surface of the tampon are better able to fill the shape and contours of the cavity when saturated body. In addition, the implementation of the grooves and / or grooves across the body of the tampon and the conical shape of the tampon with the base at the output end made at an angle provide a “break” of constant contact with the walls of the vagina, thereby preventing them from drying out. Thus absorbent the ability and prevention of drying of the walls of the vagina when using the proposed tampons are achieved better in comparison with the known tampons that do not have the proposed configuration.

• The outlet end of the tampon, elongated on one side, provides a longer section for absorbing body fluid before it leaks.

• When removing this tampon using a cord that was originally placed obliquely to the longitudinal axis Y, the tampon tilts (Fig. 3) relative to the longitudinal axis of the walls of the vagina and due to the output end extended on one side is much easier to remove.

• The proposed tampon is softer and due to the conical shape, inclined placement of the cord in the body of the tampon, execution of the base of the tampon body at the output end at an angle and a notch for the finger will be convenient even for those who have never used them before.

• The expanded outlet end of the tampon has a diameter larger than the diameter of the inlet end, which prevents accidental passage of the tampon from the vagina into the uterus.
