Glove with medicated porous beads
View Patent ↗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.
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.
