Definitions
- 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.
- 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.
- absorbent materials such as cotton, viscose rayon cotton wool, synthetic sponge, cellulose fluff, synthetic fibers, or combinations of these materials
- 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.
- tampons with grooves extending in the longitudinal direction of the tampon are known.
- 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.
- 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.
- 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 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.
- 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.
- 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.
- 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.
- the transverse grooves are not destroyed, as this occurs with grooves of a longitudinal, spiral type.
- the tampon manufacturing process is thus more efficient in terms of production time and significant reduction in material loss.
- FIG. 1 is a general view of a tampon, showing its truncated conical shape and one transverse groove that extends along the transverse axis of the tampon.
- FIG. 2 is a schematic illustration of a tampon according to the invention for illustrating the location of the groove in the transverse direction of the body tampon, as well as the inclined location of the cord to remove the tampon, made by the dotted line.
- FIG. 3 is a schematic illustration of a tampon when it is removed.
- FIG. 4 is a schematic view in which, according to the invention, the output end is provided with a finger recess and has a concave dome-shaped shape for easier handling and insertion of the tampon.
- FIG. 5 is a schematic illustration of a tampon on which a single semicircular protrusion is made in the transverse groove, extending along the entire groove.
- FIG. 6 is a schematic illustration of a tampon on which several protrusions in the form of a semicircle are made in the transverse groove, extending along the entire groove.
- FIG. 7 is a schematic illustration of a tampon on which longitudinal convex rectangular narrow protrusions are made at the bottom of the transverse groove.
- FIG. 8 is a schematic illustration of a tampon on which various convex letters are made at the bottom of the transverse groove.
- FIG. 9 is a sectional view of the grooves shown in FIG. 1-3, 5, 7 and 8.
- 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.
- 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.
- 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.
- 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.
- the protrusions and letters can be made with an angle of inclination to the X axis in the range from 45 to 135 degrees.
- 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.
- 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.
- the tampon 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.
- 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.
- the invention provides a tampon, in which the output end is provided with a recess for the finger and has a concave domed shape.
- 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).
- 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.
- the tampon 1 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.
- 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.
- 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.
- 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 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.
