BIOCIDAL ARTICLE WITH PATTERNED ADHESIVE LAYER
A biocidal article includes a biocidal material layer having edges, an exposed side, and an adhesive side opposing the exposed side. A patterned adhesive layer is located in contact with the adhesive side and extends to the edges of the biocidal material layer. The patterned adhesive layer includes a non-biocidal portion and a biocidal portion. The biocidal portion includes biocidal materials and extends to at least one edge.
1 . A biocidal article, comprising:
a biocidal material layer having edges, an exposed side, and an adhesive side opposing the exposed side; and
a patterned adhesive layer located in contact with the adhesive side and extending to the edges of the biocidal material layer wherein the patterned adhesive layer includes a non-biocidal portion and a biocidal portion, the biocidal portion including biocidal materials and extending to at least one edge, wherein the non-biocidal portion and the biocidal portion of the patterned adhesive layer have the same adhesion.
2 . The biocidal article of claim 1 , wherein the biocidal material layer and the patterned adhesive layer form a sheet.
3 . The biocidal article of claim 1 , wherein the biocidal material layer has four edges and forms a rectangular layer.
4 . The biocidal article of claim 1 , wherein the biocidal portion extends along only one edge, only two edges, only three edges, or four edges.
5 . The biocidal article of claim 1 , wherein the biocidal material layer has a length greater than a width.
6 . The biocidal article of claim 5 , wherein the biocidal material layer and the patterned adhesive layer form a tape.
7 . The biocidal article of claim 1 , wherein the patterned adhesive layer covers the adhesive side of the biocidal material layer.
8 . The biocidal article of claim 1 , wherein the patterned adhesive layer covers only a portion of the adhesive side of the biocidal material layer.
9 . The biocidal article of claim 1 , wherein the biocidal material includes biocidal particles.
10 . The biocidal article of claim 9 , wherein the biocidal particles include metal, metal salts, silver, silver salt, copper, copper salt, silver sulfate, or silver chloride.
11 . The biocidal article of claim 9 , wherein the biocidal particles are located within a binder.
12 . The biocidal article of claim 9 , wherein the biocidal material layer has a surface and the biocidal particles extend from the surface.
13 . The biocidal article of claim 1 , wherein the biocidal material includes biocidal drugs.
14 . The biocidal article of claim 1 , wherein the biocidal material layer and the patterned adhesive layer are elastic or flexible.
15 . The biocidal article of claim 1 , wherein the biocidal material layer is woven.
16 . The biocidal article of claim 1 , wherein the biocidal material layer is a textile, cloth, plastic, or fabric.
17 . The biocidal article of claim 1 , wherein the biocidal material layer has a structured surface.
18 . The biocidal article of claim 1 , wherein the biocidal material layer is hydrophobic or oleophobic.
19 . The biocidal article of claim 1 , wherein the biocidal material layer has a material color and the patterned adhesive layer has an adhesive color different from the material color.
20 . The biocidal article of claim 1 , wherein the material color is blue or green or white or wherein the adhesive color is red or orange.
21 . The biocidal article of claim 1 , wherein the biocidal material layer or the patterned adhesive layer is transparent.
22 . The biocidal article of claim 1 , wherein the biocidal portion has an edge color and the non-biocidal portion has a color that is different from the edge color.
23 . The biocidal article of claim 22 , wherein the biocidal material layer has a material color and wherein the edge color is the same as the material color.
24 . The biocidal article of claim 1 , further including a visible mark on the biocidal material layer adjacent to the at least one edge indicating the biocidal portion of the patterned adhesive layer.
25 . The biocidal article of claim 1 , further wherein at least a portion of the visible mark is the same distance from the at least one edge as the distance from the at least one edge to the non-biocidal portion.
26 . The biocidal article of claim 1 , further including a visible mark on the biocidal material layer adjacent to an edge opposite to the at least one edge indicating the non-biocidal portion of the patterned adhesive layer.
27 . The biocidal article of claim 1 , further wherein at least a portion of the visible mark is the same distance from the opposite edge as the distance from the at least one edge to the non-biocidal portion.
28 . The biocidal article of claim 1 , further including a visible mark indicating a minimum overlap and a visible mark indicating a maximum overlap.
