Embodiment Construction

[0027] Such as figure 1 and 2 As shown, the tampon of the present invention is generally indicated by the reference numeral 10 and is hereinafter referred to as tampon 10 . The tampon 10 includes an absorbent mass 12 of suitable material. The insertion end 16 is located at one end of the absorbent block 12 and the withdrawal end 18 is located at the opposite end of the absorbent block 12 . A removal strip 20 is incorporated into the absorbent block 12 near the withdrawal end 18 . The absorbent mass 12 may or may not be sleeved within a cover 14 capable of allowing menses or other bodily fluids to pass through. If cover sleeve 14 is included, removal strap 20 may be attached thereto, near withdrawal end 18 .

[0028] In its initial form ( figure 1 ), the tampon 10 is cylindrical. During use, the tampon 10 expands into an anthropometric geometry ( figure 2 ) to approximate the shape of the vaginal cavity into which the tampon is inserted. The term "anthropometrically" a...

Abstract

A tampon pledget has an absorbent mass of material and a withdrawal string located at one end thereof. During use, the tampon pledget expands to take on a geometric configuration that approximates the shape of the vagina into which the tampon pledget is inserted. An anthroprometrically expandable tampon pledget has an absorbent mass of material that is defined by a first end having a first density, a second end having a second density, and a portion intermediate the first and second ends. The material expands at different rates upon being contacted by body fluids, thereby allowing the tampon pledget to conform to the shape of a vagina. A method of making an expandable tampon pledget includes the steps of providing an absorbent material, attaching a string thereto, and compressing the material into a cylindrical shape such that a density gradient is realized over a length of the compressed material.

Description

technical field [0001] The present invention relates generally to tampons, and more particularly to tampons that expand in the vaginal cavity in response to absorption of bodily fluids. Background technique [0002] In female placental mammals, especially humans, the vagina is an elastic muscular cavity that extends from the uterus inside to the vulva outside. The narrow lower neck of the uterus forms the cervix. The entrance to the vagina is called the vaginal opening, which is located at the back of the vulva. [0003] Although there is a wide range of anatomical variations, the average length of the vaginal canal from the vaginal opening to the cervix is ​​about 3 to 5 inches. The vaginal opening has a relatively small diameter, and the bottom two-thirds of the vagina are only slightly larger, if any, than the vaginal opening. The lateral (side-to-side) width in the bottom two-thirds is generally slightly larger than the front-to-rear width, which is particularly small...
