Blister package with sloped raised formations

Abstract

A blister package with a hole in it for hanging the package on a rod has a thin plastic front sheet attached to back and a raised receptacle or blister is formed in the plastic sheet sized to enclose an article. The plastic sheet further has a raised formation near each top corner on the front of the blister package. The raised formation is shaped to space the package from an adjacent package when hung on a rod and to resist getting caught on the top edge of an adjacent blister package if the package is rotated about the rod. The raised formation has a peak and sloping sides extending from the peak toward the edges of the package. The profile is generally smooth such that there are no ledges to catch on the top edge of an adjacent blister pack. The hole is located a first distance from the top edge of the blister package and each projection is spaced a second distance from the hole. The second distance is made less than the first distance such that if the blister package were rotated 90 degrees a raised formation could not get caught on the top edge of an adjacent blister package. Preferably a bar code is provided on the outside of the back where it can be read by a bar code reader.
