Abstract

A tampon assembly includes a flexible and relatively thin impermeable portion having two opposite side faces and an outer edge which is oval in shape so that the oval shape of the impermeable portion has a largest dimension as measured through the center of the impermeable portion and a smallest dimension as measured through the center of the impermeable portion, and the largest dimension is at least about 1.5 times the size of the smallest dimension. The assembly further includes an absorbent pad portion which is secured to one side face of the impermeable portion so that when the assembly is positioned within a user, the absorbent pad portion is positioned in a condition for absorbing fluids and the outer edge of the impermeable portion sealingly engages the walls of the vaginal canal.

Claims

1. A tampon assembly positionable within the vaginal canal of a user wherein the vaginal canal has a posterior fornix and a sub-pubic portion and walls which extend between the posterior fornix and the sub-pubic portion of the canal, the assembly comprising:

a thin, saucer-shaped impermeable portion having two opposite concave and convex side faces and having an outer edge which is oval in shape so that the oval shape of the impermeable portion has a largest dimension as measured across the center of the impermeable portion and a smallest dimension as measured across the center of the impermeable portion, and the largest dimension is at least about 1.5 times the smallest dimension so as to provide the impermeable portion with a length which corresponds to the largest dimension of the oval shape; and

an absorbent portion secured to the concave side face of the impermeable portion so that when the tampon assembly is inserted lengthwise along the vaginal canal so that the largest dimension of the oval shape of the impermeable portion extends along the length of the vaginal canal, the smallest dimension of the oval shape of the impermeable portion facilitates the lengthwise movement of the assembly along the length of the canal, and so that when the tampon assembly is positioned within the vaginal canal for use, the absorbent portion is in position to absorb fluids which exit the cervix without the cervix being encapsulated by the impermeable portion and the outer edge of the impermeable portion is in sealing relationship with the vaginal walls of the user and the largest dimension of the oval shape of the impermeable portion enables the outer edge of the impermeable portion to engage the walls of the vaginal canal from the posterior fornix to the sub-pubic portion thereof; and

the absorbent portion is constructed of absorbent material which, when secured to the concave side face of the impermeable portion and the assembly is inserted into place within the vaginal canal, resists deformation of the assembly and thereby renders the assembly capable of strengthening the vaginal walls; and

the absorbent portion is sized to substantially fill the concave side face of the impermeable portion and to thereby enhance the fluid-absorbing capacity of the assembly, and

means for releasably securing the absorbent portion to the concave side face of the impermeable portion wherein the means for releasably securing includes a hook and loop fastener including a hook-providing portion and a loop-providing portion, and one of the hook-providing portion and the loop-providing portion is attached to the impermeable portion and the other of the hook-providing portion and the loop-providing portion is attached to the absorbent portion.

2. The assembly as defined in claim 1 wherein the largest dimension is about 2.0 times the smallest dimension.

5. The assembly as defined in claim 1 further comprising an amount of lubricant which is coated about the impermeable and absorbent portions to facilitate positioning of the assembly within a user and removal of the assembly from a user.

6. The assembly as defined in claim 1 wherein the absorbent portion has a side surface which faces away from the one side of the impermeable portion, and the side surface defines a concave indentation therein which is substantially centrally disposed therein for collecting fluids which exit the cervix.

7. A tampon assembly positionable within a vaginal canal and adjacent the cervix of a user wherein the vaginal canal has a posterior fornix and a sub-pubic portion and walls which extend between the posterior fornix and the sub-pubic portion of the canal, said assembly comprising:

an absorbent pad portion which is secured to the one concave side face of the impermeable portion so that when the assembly is inserted lengthwise along the vaginal canal so that the largest dimension of the oval shape of the impermeable portion extends along the length of the vaginal canal, the smallest dimension of the oval shape of the impermeable portion facilitates the lengthwise movement of the assembly along the length of the canal, and so that when the assembly is positioned within the vaginal canal for use, the absorbent pad portion is disposed between the cervix and the impermeable portion for absorbing fluids which exit the cervix without the cervix being encapsulated by the impermeable portion, and the outer edge of the impermeable portion sealingly engages the walls of the vaginal canal and the largest dimension of the oval shape of the impermeable portion enables the outer edge of the impermeable portion to engage the walls of the vaginal canal from the posterior fornix to the sub-pubic portion thereof; and

the absorbent pad portion is constructed of absorbent material which, when secured to the concave side face of the impermeable portion and the assembly is inserted into place within the vaginal canal, resists deformation of the assembly and thereby renders the assembly capable of strengthening the vaginal walls; and

the absorbent pad portion is sized to substantially fill the concave side face of the impermeable portion and to thereby enhance the fluid-absorbing capacity of the assembly; and

means for releasably securing the absorbent pad portion to the concave side face of the impermeable portion wherein the means for releasably securing includes a hook and loop fastener including a hook-providing portion and a loop-providing portion, and one of the hook-providing portion and the loop-providing portion is attached to the impermeable portion and the other of the hook-providing portion and the loop-providing portion is attached to the absorbent pad portion.

8. The assembly as defined in claim 7 wherein the largest dimension is about 2.0 times the smallest dimension.

9. The assembly as defined in claim 7 wherein the outer edge of the impermeable portion is elliptical in shape.

10. The assembly as defined in claim 7 wherein the absorbent pad portion is substantially platen in shape and has an outer edge which is similar in shape to the outer edge of the impermeable portion, the absorbent pad portion is positioned against the concave side face of the impermeable portion in a concentric relationship with the outer edge thereof and possesses no part which extends outboard of the outer edge of the impermeable portion.

11. The assembly as defined in claim 10 wherein the impermeable portion includes an inwardly-directed lip which extends along the outer edge, and the absorbent pad portion is captured beneath the inwardly-directed lip when the absorbent pad portion is secured to the one concave side face.

12.
