Problems solved by technology

The device also has the disadvantage that only an external placement of the secondary absorbent element is feasible
[0009] Although the devices described above, and most of the other tampons currently available, are successful and widely accepted in the marketplace, research continues to improve absorbent tampons

Embodiment Construction

[0027] The present invention relates to improved absorbent tampons having enhanced leakage protection. During the course of the present research, several potential mechanisms other than simple shunting have been found to contribute to tampon leakage. Without wishing to be bound by theory, some of these mechanisms can be explained by the following observations. It has been found that in the event of a tampon leak, a stain develops on the drawstring of many existing tampons. Thus, the drawstring of many existing tampons can provide a "drain" path for menstrual blood that emerges at the bottom of the vagina.

[0028] During a tampon change, some residual menstrual blood may remain near the vaginal opening. It may be fluid that was previously absorbed, but then "squeezed" by the tampon as it was drawn through the vaginal sphincter. This residual fluid, especially if located near the vaginal opening (ie, in the lower part of the vaginal canal), may not be effectively absorbed by...

Abstract

This invention relates to absorbent tampons. More particularly, the invention relates to an improved absorbent tampon having improved leakage performance. Tampons, having a primary absorbent member which is constructed from an absorbent material compressed to a self-sustaining form and a mass of secondary absorbent material are disclosed. The mass of secondary absorbent material is preferably located generally proximate the withdrawal end of the primary absorbent member, and is preferably substantially non-compress, and preferably of a smaller diameter than the primary absorbent member. The mass of secondary absorbent material may be a multiple pieces or one piece. The secondary absorbent material may be attached to the primary absorbent member, the withdrawal cord, or both, or may be integral with one or both of these members. The withdrawal cord of the tampon may have absorbent and non-absorbent zones, especially when the mass of secondary absorbent material is attached to the withdrawal cord. The mass of secondary absorbent material preferably has a lower total absorbency than the primary absorbent member. Preferably, the mass of secondary absorbent material is provided with a driving force to direct fluid toward the primary absorbent member. A preferred method of making a tampon of the present invention is also disclosed.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 00805630.7, the application date being March 27, 2000, and the invention title being "tampon with enhanced leakage protection". technical field [0002] This invention relates to absorbent tampons. More particularly, the present invention relates to an improved absorbent tampon having enhanced leakage protection. This is accomplished with tampons comprising a primary absorbent member and a mass of secondary absorbent material disposed adjacent the pull end of the primary absorbent member. Background technique [0003] A wide variety of absorbent tampons have long been known in the art. The most common tampons commercially available today are made from a tampon dressing that has been compressed into a generally cylindrical shape. Various types and configurations of tampon pledgets have been described in the art. Prior to compression, the pledget is ro...
