Abstract

An elastomeric article includes a substrate body formed from an elastomeric material, and a plurality of porous beads capable of containing a treatment within the pores of the beads and dispensing the treatment to an end user.

Claims

1. An elastomeric article comprising:

a substrate body including a hydrocarbon-based elastomeric polymeric matrix;

a plurality of porous beads having a pore size that ranges from about 0.01 microns to about 0.5 microns, the beads containing a treatment impregnated within said pores, the treatment being time-releasable to an environment; and

each of said beads has a surface with at least a vinyl functional group, and said bead is covalently bonded to said elastomeric polymer matrix or a coating thereon.

2. The article according to claim 1, wherein said vinyl group is selected from the group consisting of a carbon-carbon vinyl group and an acrylate group.

3. The article according to claim 1, wherein said porous bead has a porosity of about 0.1% to about 90% of the entire volume of said bead.

4. The article according to claim 3, wherein said porous bead has a porosity of about 20% to about 90% of the entire volume of said bead.

5. The article according to claim 1, wherein said porous beads are present in an amount of from about 0.0001 mass % to about 10 mass % of said article.

6. The article according to claim 1, wherein said porous beads do not plasticize, dissolve, dissociate, or degrade during formation of said article.

7. The ankle according to claim 1, wherein said porous beads arc formed from a material that either has or does not have hydrocyl functionality, but can be surface converted to produce hydroxyl groups on a surface of said beads.

8. The article according to claim 1, wherein either a diffusion mechanism or a shearing force mechanism is employed to control timed-release of said treatment.

9. The article according to claim 1, wherein said treatment includes a moisturizer, an ointment, a drug, or an emollient.

10. The article according to claim 1, wherein said treatment enhances skin-health.

11. The article according to claim 10, wherein said treatement is selected from the group consisting of aloe, vitamin E, lanolin, polyethylene glycol, glycerin, and mineral oil.

12. The article according to claim 1, wherein said environment comprises an end user'"'"'s skin.

13. The article according to claim 1, wherein said coating on said elastomer polymer matrix comprises a donning layer.

14. The article according to claim 1, wherein said porous beads are present in an amount of about 0.01 mass % to about 80 mass % of said donning layer.

15. The article according to claim 1, wherein said porous beads are present on an inside surface.

16. An elastomeric article comprising:

an elastomeric substrate body having a first surface; and

a donning layer overlying said first surface, the donning layer comprising a polymer material containing a plurality of porous beads with a surface having reactive vinyl functional groups, said beads are covalently bonded to either said substrate body or said donning layer by means of a C—

C bond.

17. The elastomeric article according to claim 16, where said beads contain a time-releasable treatment in a number of pores.

18. The elastomeric article according to claim 16, wherein said polymer material comprises a hydrogel.

19. The elastomeric article according to claim 16, wherein said elastomeric substrate body has a second surface distal from said donning layer, and said second surface contains a plurality of porous beads covalently attached to said second surface.

20. The article according to claim 16, wherein said article is either a glove or a condom.
