In some arrangements, the sterility margin is attached to or integral with a lower liner on a lower surface of the adhesive patch. In other arrangements, the sterility margin is attached to or integral with an upper liner on an upper surface of the adhesive patch. ## Claims ### Claim 1 A drug delivery device comprising: a housing having a bottom wall; an adhesive patch adhered to the bottom wall and having an area contained within an outer perimeter, the area having an upper surface, a lower surface, and an edge surface at the outer perimeter between the upper surface and the lower surface; a bacteria impermeable lower liner on the lower surface; and a bacteria impermeable sterility margin surrounding and abutting the edge surface of the adhesive patch, wherein the outer perimeter of the adhesive patch is pre-cut to separate from the sterility margin. ### Claim 2 (depends on 1) The drug delivery device of claim 1, wherein the bacteria impermeable sterility margin is attached to or integral with the adhesive patch or the lower liner. ### Claim 3 (depends on 1) The drug delivery device of claim 1, further comprising a bacteria impermeable upper liner on the upper surface, wherein the sterility margin is optionally attached to or integral with the upper liner. ### Claim 4 (depends on 1) The drug delivery device of claim 1, wherein the outer perimeter of the adhesive patch is pre-cut in a perforated manner to separate from the sterility margin. ### Claim 5 (depends on 1) The drug delivery device of claim 1, wherein the housing includes an interior space and a top wall, a container is disposed within the interior space, and the top wall includes a window positioned to allow viewing of the container, the window including a polarized filter that filters out up to and including 50% of light in the visible range. ### Claim 6 An adhesive system for use with a wearable drug delivery device, the system comprising: an adhesive patch having an outer perimeter, an upper surface, a lower surface, and an edge surface at the outer perimeter and extending between the upper surface and the lower surface; a bacteria impermeable lower liner on the lower surface; and a bacteria impermeable sterility margin surrounding and abutting the edge surface of the adhesive patch, wherein the outer perimeter of the adhesive patch is pre-cut to separate from the sterility margin. ### Claim 7 (depends on 6) The adhesive system of claim 6, wherein the bacteria impermeable sterility margin is attached to or integral with the adhesive patch or the lower liner. ### Claim 8 (depends on 6) The adhesive system of claim 6, further comprising a bacteria impermeable upper liner on the upper surface, wherein the sterility margin is optionally attached to or integral with the upper liner. ### Claim 9 (depends on 8) The adhesive system of claim 8, wherein the upper liner includes a pre-cut first perimeter surrounding a portion of an area of the adhesive patch that is configured to be adhered to a drug delivery device. ### Claim 10 (depends on 6) The adhesive system of claim 6, further comprising a hole provided in the area to allow passage of a delivery member of the drug delivery device. ### Claim 11 (depends on 6) The adhesive system of claim 6, wherein the outer perimeter is pre-cut in a perforated manner to separate from the sterility margin. ### Claim 12 (depends on 6) The adhesive system of claim 6, wherein the sterility margin has a width of at least two millimeters.
