Abstract

A tampon comprising a rigid conical end for entry into the cavity of a body. Extending from the base of the conical end is a bulb-shaped body made of highly absorbable and expansible material. Disposed within the tampon body is a rupturable container holding a liquid medicant. Immediately before or during the insertion of the tampon into the cavity of the body, the container is ruptured, releasing the liquid medicant to be absorbed by the tampon body. After the tampon body is inserted into the cavity of the body, the tampon body expands radially about the longitudinal axis thereof from the absorption of the liquid medicant. The lips of the cavity of the body grasp the neck of the tampon body and the expanded tampon body engage the walls surrounding the cavity of the body inwardly of the lips for inhibiting unintentional expelling of the tampon from the cavity of the body and for providing direct contact between the medicated tampon body and the walls surrounding the cavity of the body.

Claims

1. A tampon with a longitudinal axis for insertion in the longitudinal direction thereof into the cavity of a body in which lips surround the entranceway of the body cavity and walls surround the body cavity inwardly of the lips, said tampon comprising:

(a) a rigid entry end for insertion into the body cavity through the lips surrounding the entranceway of the body cavity;

(b) a liquid absorbable, expansible bulb-shaped tampon body extending from said entry end, said tampon body being constructed to expand radially outward from the longitudinal axis of said tampon after absorbing liquid, said bulb-shaped tampon body being formed with an ovate portion and a neck portion; and

(c) a rupturable container with liquid medicant therein disposed within the ovate portion of said tampon body, said container being rupturable to release the liquid medicant therein to be absorbed by said tampon body for expanding said tampon body radially outward from the longitudinal axis of said tampon, after said tampon is inserted into the body cavity, the lips surrounding the entranceway of said body cavity grasp said neck portion of said tampon body and the expanded ovate portion of said tampon body with absorbed liquid medicant contacts the walls surrounding the body cavity inwardly of the lips surrounding the entranceway of the body cavity to apply liquid medicant to the walls surrounding the body cavity.

2. A tampon as claimed in claim 1 and further comprising an absorbable envelope surrounding said tampon body to limit the extent of expansion of said tampon body after said tampon body absorbs liquid medicant.

3. A tampon as claimed in claim 1 wherein said neck portion of said tampon body expands radially outward from the longitudinal axis of said tampon after said tampon body absorbs the liquid medicant for applying liquid medicant to the lips grasping the neck portion of the tampon body.

4. A tampon as claimed in claim 3 and further comprising an absorbable bulb-shaped envelope surrounding the bulb-shaped tampon body, said envelope including an ovate portion surrounding the ovate portion of said tampon body and a neck portion surrounding the neck portion of said tampon body to limit the extent of expansion of said tampon body after said tampon body absorbs liquid medicant.

5. A tampon as claimed in claim 1 and further comprising a protector integrally formed with the neck portion of said tampon body and projecting radially outward from the longitudinal axis of said tampon beyond said neck portion of said tampon body to protect the user from soiling clothing resulting from substances discharged through the lips surrounding the entranceway to the body cavity.

6. A tampon as claimed in claim 4 and further comprising a protector integrally formed with the neck portions of said tampon body and said envelope and projecting radially outward from the longitudinal axis of said tampon beyond said neck portions of said tampon body and said envelope to protect the user from soiling clothing resulting from substances discharged through the lips surrounding the entranceway to the body cavity.

7. A tampon as claimed in claim 5 wherein said protector comprises absorbable material facing said lips and impervious material forming an outer layer thereof.

8. A tampon as claimed in claim 6 wherein said protector comprises absorbable material facing said lips and impervious material forming an outer layer thereof.

9. A tampon as claimed in claim 1 wherein said rigid entry end has a conical configuration with a base and said tampon body extends from the base of said entry end.

10. A tampon as claimed in claim 4 wherein said rigid entry end has a conical configuration with a base and said tampon body extends from the base of said entry end.
