Bi-directionally positionable tampon
Bi-directionally positionable tampon configured to be disposed in a vaginal opening adjacent to a cervical os for absorbing and collecting vaginal discharge. The tampon includes an elastomeric ring to support an absorbent pad for collecting and absorbing bodily fluids. To support the absorbent pad, the elastomeric ring has a first circular-shaped edge and a second circular-shaped edge that surrounds the central aperture. A covering comprising a first pervious layer and a second pervious layer disposed adjacent to the first pervious layer is attached to the elastomeric ring and disposed at least partially in the central aperture of the ring. An absorbent pad is disposed in a cavity formed between the first fabric layer and the second fabric layer of the covering. When the elastomeric ring is disposed in a vaginal opening, bodily fluid can pass through either the first and/or second pervious layers to reach the absorbent pad.
1 . A tampon, comprising:
an elastomeric ring comprising an inner surface, an outer surface, a first circular-shaped edge, and a second circular-shaped edge opposite the first circular-shaped edge, wherein the inner surface defines a central aperture;
a covering attached to the elastomeric ring along the inner surface, the covering positioned within the central aperture with an entirety of the covering positioned between the first circular-shaped edge and the second circular-shaped edge, the covering comprising a first pervious layer and a second pervious layer at least partially defining a cavity therebetween, the first pervious layer and the second pervious layer being of a substantially same surface area, the first pervious layer comprising a first pervious material and the second pervious layer comprising a second pervious material; and
an absorbent pad floatingly positioned within the cavity and substantially centered between the first circular-shaped edge and the second circular-shaped edge;
wherein a first portion of the inner surface extends beyond the first pervious layer to the first circular-shaped edge to define a first collection chamber bounded by the first portion of the inner surface and the first pervious layer; and
wherein a second portion of the inner surface extends beyond the second pervious layer to the second circular-shaped edge to define a second collection chamber bounded by the second portion of the inner surface and the second pervious layer.
2 . The tampon of claim 1 , wherein the tampon is symmetrical about a central plane perpendicular to a central axis defined by the elastomeric ring, the central plane extending through a center of the elastomeric ring between the first circular-shaped edge and the second circular-shaped edge.
3 . The tampon of claim 1 , wherein the covering is configured to be stretched up to 40% in any direction without the covering tearing.
4 . The tampon of claim 1 , wherein the first pervious material comprises a first fabric material, and the second pervious material comprises a second fabric material.
5 . The tampon of claim 4 , wherein each of the first pervious material and the second pervious material comprises a woven, jersey knit cotton.
6 . The tampon of claim 1 , wherein each of the first pervious material and the second pervious material comprises at least one of:
an extensible, non-woven polyolefin; and
an extensible, non-woven polyester.
7 . The tampon of claim 1 , wherein the first pervious layer and the second pervious layer completely define the cavity therebetween, with annular portions of the first pervious layer and the second pervious layer being sewn or otherwise bonded to one another around the cavity.
8 . The tampon of claim 1 , wherein each of the first pervious material and the second pervious material are configured to allow passage of vaginal discharge.
9 . The tampon of claim 1 , wherein the first pervious layer and the second pervious layer are fenestrated.
10 . The tampon of claim 1 ,
wherein the covering is attached to the inner surface of the elastomeric ring midway between the first circular-shaped edge and the second circular-shaped edge.
11 . The tampon of claim 1 , wherein the first pervious layer and the second pervious layer are a same size.
12 . The tampon of claim 1 , wherein the elastomeric ring is configured to span a vaginal opening adjacent to a cervical os.
13 . The tampon of claim 1 , wherein the elastomeric ring comprises a circular-shaped elastomeric ring.
14 . The tampon of claim 1 , wherein the elastomeric ring has a generally rectangular transverse cross-section such that a height of the transverse cross-section is greater than a width of the transverse cross-section.
15 . The tampon of claim 1 , wherein the elastomeric ring is configured to deform from a circular shape with an initial diameter to an oval shape, wherein a longest diameter of the oval shape is greater than the initial diameter of the circular shape.
16 . The tampon of claim 1 , wherein the covering is attached to the elastomeric ring by a permanent attachment.
17 . The tampon of claim 16 , wherein the permanent attachment comprises overmolding.
18 . The tampon of claim 1 , wherein the covering is attached to the elastomeric ring by a releasable attachment.
19 . The tampon of claim 18 , wherein the releasable attachment comprises a clam-shell.
20 . The tampon of claim 1 , wherein the absorbent pad is configured to absorb vaginal discharge.
21 . The tampon of claim 1 , wherein the absorbent pad comprises non-woven, spunlaced cotton.
22 . The tampon of claim 1 , wherein the absorbent pad has a smaller diameter than the central aperture.
23 . The tampon of claim 1 , being devoid of glue.
24 . The tampon of claim 1 , wherein the first pervious layer, the second pervious layer, and the absorbent pad are generally planar.
25 . The tampon of claim 1 , wherein the first collection chamber and the second collection chamber are on opposing sides of the absorbent pad such that the tampon may be used bi-directionally.
