Patent number: 5502911Abstract: A device for display of a container which comprises a display frame attached to the grocery store shelf. This frame extends from the edge of the shelf to which it is attached. This frame is generally rectangular in configuration. Attached to the frame are container holding means, which container holding means are capable of fixedly holding an attached container thereon. These container holding means are fixedly held against the frame. Similarly, there is a container fixedly held against the frame, generally by such means as rivets, adhesive or screws. Attached to the container is a cap, also fixedly attached, either to the frame or to the container itself. Therefore, the user is able to attempt to operate the analgesic container cap, and the display device is able to attract customers, and yet neither container or the cap is taken by a potential customer, therefore depriving other customers of use of this sample.Type: GrantFiled: March 14, 1994Date of Patent: April 2, 1996Assignee: McNeil-PPC, Inc.Inventors: Colin F.
