Abstract

The present application generally relates to support articles and methods of making and using them. Some embodiments of the support articles of the present disclosure provide compression and/or stabilization to sore joints, tendons, or muscles. In some embodiments, the compression and/or enhanced stabilization is provided, at least in part, by one or more reinforcing portions. In some embodiments, the support articles can easily be applied by a non-trained user and can be worn in many conditions (including, for example, in the shower or during exercise) for up to three days. In some embodiments, the support articles or support articles also have a relatively slim profile and are thus discreet such that they can be worn under clothing without being noticeable. In some embodiments, the support articles eliminate or reduce joint or muscle pain or soreness.

Claims

1. A support article, comprising:

a backing having a front major surface and a rear major surface;

an adhesive adjacent to least a portion of the rear major surface of the backing, the adhesive capable of adhering the support article to the user; and

one or more reinforcing portions adjacent to at least a portion of the rear major surface of the backing or the front major surface of the backing.

2. The support article of claim 1, further including a release liner adjacent to at least a portion of the adhesive.

3. The support article of claim 1, wherein the backing includes at least one of a polyurethane film, a polyethylene film, a polypropylene film, a PVC film, a nonwoven material, and/or a woven material.

4. The support article of claim 1, wherein the backing includes at least one of a polyolefin, polyester, polyalkylene, polyamide, polystyrene, polyarylsulfone, polydiene, and/or polyurethane.

5. The support article of claim 1, wherein the backing includes conjugate multicomponent melt spun fibers.

6. The support article of claim 1, wherein at least one of the backing or the backing and adhesive combination has a breathability and/porosity of between about 3 and about 12 mm H₂O measured using the pressure drop test.

8. The support article of claim 1, wherein at least one of the backing or the backing and adhesive combination has a cross-directional tensile strength of between about 4 lbf (17.8 N) and about 9 lbf (40.0 N) and/or a machine-directional tensile strength of between about 5 lbf (22.2 N) and about 10 lbf (44.5 N).

9. The support article of claim 1, wherein at least one of the backing or the backing and adhesive combination has a cross-directional elongation at break of between about 600% and about 900% and/or a machine-directional elongation at break of between about 350% and about 1000%.

12. The support article of claim 1, wherein the adhesive is a pressure sensitive adhesive and is selected from at least one of the following adhesive classes:

polyacrylate adhesives, polyalphaolefin adhesives, polyvinyl acrylates, rubber resin adhesives, silicone adhesives, polydiorganosiloxane polyurea compolymers, and mixtures thereof.

13. The support article of claim 1, wherein the backing and adhesive form a conjugate multicomponent system.

14. The support article of claim 1, wherein the reinforcing portion(s) cover between about 10% and about 75%.

15. The support article of claim 1, wherein the one or more reinforcing portions include at least one of foam or a shaped memory material.

16. The support article of claim 1, wherein the one or more reinforcing portions comprise:

an adhesive layer having first and second major surfaces;

a first foam layer adjacent to first major surface of the adhesive layer;

a second foam layer adjacent to second major surface of the adhesive layer;

a first skin layer adjacent to first foam layer; and

a second skin layer adjacent to second foam layer.

17. The support article of claim 16, further including microspheres in at least one of the first or second foam layers.

18. The support article of claim 1, wherein the one or more reinforcing portions has a Shore A hardness is between about 10 and about 100 when measured according to ASTM D2240 and/or a Shore D hardness of between about 10 and about 60 when measured according to ASTM D2240.

19. The support article of claim 1, wherein the one or more reinforcing portions has a cross-directional tensile strength of between about 13 lbf (57.8 N) and about 28 lbf (129.0 N) and/or a machine-directional tensile strength of between about 16 lbf (71.2 N) and about 31 lbf (137.9 N).

21. The support article of claim 1, wherein the one or more reinforcing portions have an elongation at break of between about 10% and about 50%.

23. The support article of claim 1, comprising at least two reinforcing layers that are on layered on one another.

24. The support article of claim 1, wherein at least one of the reinforcing portions is separate from the support article and can be independently applied by the user before the full support article is applied.
