Abstract
An improved tampon is provided having one or more loops placed entirely through the tampon for ease in insertion and removal of an attached spherical member into and from a body cavity. Moreover, the improved tampon can be impregnated at select depths with specific spermicides, anti-infectives, lubricants, hormones, antioxidants, amino acids, etc., to allow release of inner-impregnated fluids from the member into the body cavity. Closely controlled impregnation and/or coating of the tampon is achieved by a method of manufacture employing one or more sonic baths containing necessary impregnating and/or coating fluids.
Claims12
A tampon comprising:
- a porous spherical member having an outer region and an inner region, and a first passage placed completely through said member, said inner region is configured radially inside said outer region;
- a first cord extending through said first passage and fastened at both ends to form a loop encircling at least 40% of a total cross-sectional area of the spherical member;
- a spermicide placed within the pores throughout the inner region of said member;
- and
- a lubricant placed within the pores throughout the outer region of said member.
A tampon configured for insertion by a user into a body cavity comprising:
- a porous spherical member having an outer region completely surrounding an inner region, said outer region is impregnated with a lubricant and said inner region is impregnated with a spermicide, and a first passage placed completely through said member;
- and
- a loop placed through said first passage and encircling a first portion of said spherical member, said member is capable of collapsing along an axis perpendicular to said first passage when said loop is drawn from said member during use.
