Heating or cooling mat

摘要

The invention concerns a heating or cooling mat (1) with a carrying sheet (2) having a top side (9) and a bottom side (11), and at least one heating and cooling unit (5) located on the carrying sheet (2), an adhesive being located on the bottom side (11) of the carrying sheet (2). It is endeavored to improve the handling properties of the heating or cooling mat. For this purpose, the adhesive is located on a double-sided adhesive tape (12), which is fixed on the bottom side (11) of the carrying sheet (2), the adhesive on the bottom side of the adhesive tape (12) being covered by the top side of the carrying sheet (2) and the adhesive tape (12) bonding with the top side of the carrying sheet (2) in the rolled up state of the heating or cooling mat (1).

主权项

1. A heating or cooling mat comprising:
a carrying sheet having a top side and a bottom side; at least one heating or cooling unit located on the carrying sheet; an adhesive strip fixed on the top side of the carrying sheet, the adhesive strip fixing the at least one heating or cooling unit to the carrying sheet; a double-sided adhesive tape having adhesive on a bottom side and a top side, the double-sided adhesive tape being fixed on the bottom side of the carrying sheet opposite the adhesive strip, wherein the adhesive strip and the double-sided adhesive tape are arranged such that the adhesive on the bottom side of the double-sided adhesive tape bonds with a top side of the adhesive strip when the heating or cooling mat is rolled up; wherein the carrying sheet is permeable for adhesive, such that the double-sided adhesive tape and the adhesive strip bond with each other through the carrying sheet wherein the adhesive strip has a surface with a non-stick coating, which causes a substantially poorer bonding engagement with the adhesive on the bottom side of the adhesive tape than the bonding engagement of the adhesive of the adhesive strip with the to side of the carrying sheet.
