ABSTRACT:
A getter sheet is secured within a package element in a condition of elastic deformation by positioning the getter sheet between a base and a cap of a package with at least one portion of the getter sheet in contact with the package. When positioned within the package, the condition of elastic deformation may force the getter sheet into a vaulted form. Therefore, the getter sheet may be secured within the package without utilizing any additional parts or fasteners. The getter sheet comprises particulates of a getter applied to a sheet of material. The getter sheet may comprise a rectangular shape, an elliptical shape, or an octagonal shape. The getter sheet may be secured within the package when at least one portion of the getter sheet contacts one or more of a side surface of the cap, a bottom surface of the cap, and a top surface of the base.
