The lid is hingeably connected to the base and has a user input region and a protrusion projecting into the well. The closure structure is configured for releasably retaining the lid in a closed position relative to the base. The adhesive deposit is located within the well and at least partially surrounds the protrusion, and forms a first plurality of adhesive bonds with the well and a second plurality of adhesive bonds with the protrusion. The second plurality of adhesive bonds and the closure structure are configured to exert a combined retention force of at least 20N.
