Abstract

The present application generally relates to support articles and methods of making and using them. The support articles of the present disclosure provide compression and/or stabilization of sore joints of muscles. In some embodiments, the compression and/or enhanced stabilization is provided, at least in part, by one or more straps. In some embodiments, the support articles also include 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. The support articles have a relatively slim profile and are thus discreet such that they can be worn under clothing without being noticeable.

First claim

What is claimed is:

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 a user; wherein the backing and adhesive combination has a cross-directional tensile strength of between 4 lbf (17.8 N) and 9 lbf (40.0 N) and/or a machine-directional tensile strength of between 5 lbf (22.2 N) and 10 lbf (44.5 N); and
a strap attached or adhered to the front major surface of the backing, the strap comprising a material that can stretch and/or extend by at least 25%.

2. The support article of claim 1 , wherein the strap includes at least one of the following: a polyolefin, a modified polyolefin, a polyvinyl chloride, a polycarbonate, polystyrene, polyester, polylactide, polyvinylidene fluoride, (meth)acrylic, urethane, acrylic urethane, ethylene vinyl acetate copolymer, acrylate-modified ethylene vinyl acetate polymer, ethylene acrylic acid copolymers, nylon, engineering polymer, or elastomer.

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

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

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 3 and 12 mm H 2 O measured using the pressure drop test.

7. The support article of claim 1 , wherein the backing has a weight of between 25 gsm to 300 gsm.

8. 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 600% and 900% and/or a machine-directional elongation at break of between 350% and 1000%.

9. The support article of claim 1 , wherein the backing has a thickness of 0.01 cm to 1 cm.

10. 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.

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

12. The support article of claim 1 , further including 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.

13. The support article of claim 12 , 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.

14. The support article of claim 12 , comprising at least two reinforcing layers that are on layered on one another.

15. The support article of claim 12 , wherein the support article has a weight of between 20 gsm and 500 gsm.

16. The support article of claim 12 , 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.

17. The support article of claim 1 , wherein the support article is applied to or sized for application to at least one of the IT band, hip, calf, shin, quads, hamstrings, groin, hip flexor, gluteus, outer knee, inner knee, Osgood shlatter, back of knee, front of knee, Achilles tendon, ankle, ball of foot, top of foot, heel, toe, finger, SI joint, low back, middle back, ribs, spine, abdominal, neck, shoulder, rotator cuff, AC joint, wrist, elbow, thumb, bicep, and/or tricep.

18. A method of applying a support article, comprising:
removing a liner from a rear major surface of the support article to expose an adhesive;
positioning the support article adjacent to a user's body in a desired location;
applying the support article to the user such that the adhesive contacts the user's skin;
putting pressure on the support article to cause the adhesive to adhere to the user's skin;
removing one or more liners from a rear major surface of a strap on the support article;
grasping one or more portions of the strap and elongating it; and
applying and extending the strap to the user such that the strap adhered to the support article or user's skin; wherein the support article comprises: 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 a user; and a strap attached or adhered to the front major surface of the backing, the strap comprising a material that can stretch and/or extend by at least 25%; wherein the backing and adhesive combination has a cross-directional tensile strength of between 4 lbf (17.8 N) and 9 lbf (40.0 N) and/or a machine-directional tensile strength of between 5 lbf (22.2 N) and 10 lbf (44.5 N).
