Abstract
Disposable insole pads and use thereof are disclosed. The disposable insole pads are multilayer structures comprising a topsheet and a pressure sensitive adhesive, and optionally a backsheet, silicone coating and liner layers. The pressure sensitive adhesive layer allows the disposable insole pads to be positioned, repositioned and removed, making them well suited for daily use and disposal.
Claims20
A disposable shoe pad having a multilayer structure comprising:
- a. a topsheet;
- b. an adhesive layer;
- and
- c. optionally, a release liner;
- wherein the adhesive is a pressure sensitive adhesive having a storage modulus (G′) of greater than 1×102 to less than 1×104 Pascal at 40° C.
A kit comprising:
- a. a support structure having a first side and a second side, and
- b. a disposable insole pad having a multilayer structure comprising:
- i. a top sheet;
- ii. a pressure sensitive adhesive layer having a storage modulus (G′) of greater than 1×102 to less than 1×104 Pascal at 40° C.;
- and
- iii. optionally, a release liner;
- wherein the adhesive layer of the disposable insole pad adheres onto the first side of the support structure.
A linerless, disposable pad comprising a topsheet having a top side and a bottom side and a length and a width,
- wherein the disposable pad is perforated along the cross-section perpendicular to the length of the pad;
- wherein the bottom side is coated with a pressure sensitive adhesive having a storage modulus (G′) of greater than 1×102 to less than 1×104 Pascal at 40° C.;
- and
- wherein the top side is optionally coated with a silicone release agent.
A linerless, disposable pad comprising a topsheet having a first side and a second side and having a length X,
- wherein the pad is foldable in a butterfly flap, having ¼ X fold at a left end and ¼ X fold at a right end, ½ X fold at a middle;
- whereby the second side is on the inside fold and the first side is on the outside fold;
- wherein the first side of the ¼ left fold and the ¼ right fold are coated with a pressure sensitive adhesive having a storage modulus (G′) of greater than 1×102 to less than 1×104 Pascal at 40° C.;
- and
- wherein the first side of the middle ½ X fold is optionally coated with a silicone release.
A receptable housing comprising a roll of a plurality of linerless, disposable pad
- wherein the linerless, disposable pad comprises a topsheet having a top side and a bottom side,
- the bottom side is coated with a pressure sensitive adhesive having a storage modulus (G′) of greater than 1×102 to less than 1×104 Pascal at 40° C.;
- the top side is optionally coated with a silicone release agent;
- and
- wherein the pad dispenses singly from the receptable housing.
