POLYMERIC RINGS
Polymeric rings may be provided with an inner band formed of a polymeric material; and an outer band attached to the inner band and defining a channel about an inner circumference thereof, such that the inner band is uniformly disposed within the channel. In some embodiments, the outer band has a first outer diameter and a first inner diameter and defines a channel of a channel diameter, greater than the first inner diameter, in an inner surface of the outer band, the channel having a cross-sectional shape and a mating surface; and an inner band having a second outer diameter substantially equal to the channel diameter and a second inner diameter substantially equal to the first inner diameter, the inner band having the cross-sectional shape, the inner band being disposed in the channel and having a roughened outer surface attached to the mating surface of the channel.
1 . A ring, comprising:
an inner band formed of a polymeric material; and
an outer band attached to the inner band and defining a channel about an inner circumference thereof, such that the inner band is uniformly disposed within the channel.
2 . The ring of claim 1 , wherein an outer surface of the inner band is textured to have a non-smooth surface prior to attachment with the outer band.
3 . The ring of claim 1 , wherein an inner surface of the outer band is textured to have a non-smooth surface prior to attachment with the inner band.
4 . The ring of claim 1 , wherein the outer band is attached to the inner band by over-molding the outer band around the inner band.
5 . The ring of claim 1 wherein the outer band is attached to the inner band by heat welding the outer band around the inner band.
6 . The ring of claim 1 , wherein the outer band is made of the polymeric material.
7 . The ring of claim 1 wherein the inner band has a first color or pattern of colors and the outer band has a second color or pattern of colors, different from the first color or pattern of colors.
8 . The ring of claim 1 wherein the inner band defines a grooved inner surface.
9 . The ring of claim 1 , wherein a cross-sectional shape of the inner band and the channel defined about an inner circumference of the outer band is substantially rectangular.
10 . A ring, comprising:
an outer band formed of a polymeric material; and
an inner band, attached uniformly to the outer band within a channel defined on an inner surface of the outer band.
11 . The ring of claim 10 , wherein an outer surface of the inner band is textured to have a non-smooth surface prior to attachment with the outer band.
12 . The ring of claim 10 , wherein an inner surface of the outer band is textured to have a non-smooth surface prior to attachment with the inner band.
13 . The ring of claim 10 , wherein the outer band is attached to the inner band by over-molding the outer band around the inner band.
14 . The ring of claim 10 , wherein the outer band is attached to the inner band by heat welding the outer band around the inner band.
15 . The ring of claim 10 , wherein the outer band is made of the polymeric material.
16 . The ring of claim 10 , wherein the inner band has a first color or pattern of colors and the outer band has a second color or pattern of colors, different from the first color or pattern of colors.
17 . The ring of claim 10 , wherein the inner band defines a grooved inner surface.
18 . The ring of claim 10 , wherein a cross-sectional shape of the inner band and the channel defined about an inner circumference of the outer band is substantially rectangular.
19 . A ring, comprising:
an outer band having a first outer diameter and a first inner diameter and defining a channel of a channel diameter, greater than the first inner diameter, in an inner surface of the outer band, the channel having a cross-sectional shape and a mating surface; and
an inner band having a second outer diameter substantially equal to the channel diameter and a second inner diameter substantially equal to the first inner diameter, the inner band being formed of a polymeric material and having the cross-sectional shape, the inner band being disposed in the channel and having a roughened outer surface attached to the mating surface of the channel.
20 . The ring of claim 19 , wherein the outer band is attached to the inner band by over-molding the outer band around the inner band.
