11 and 12 are essentially the same as the arrangement shown in fig6 where tray 10 110 has side walls 18 or 118 if such version of assembly 140 is used however in these embodiments side walls 18 118 and trays 10 110 are connected into a joint assembly 50 150 rather than individual assemblies 140 all of the above described embodiments offer a product package pusher assembly 40 140 that can be durably constructed from vacuum thermoformed constituent parts tray 10 110 and pusher arm 20 120 as noted above the benefit of vacuum forming the components is that unlike rigid injection molded parts when assembled the injection molded parts must be engineered to allow clearance tolerances when assembling the vacuum formed parts can be designed with interference due to the part 39 s ability to flex and deform to temporarily accommodate mechanical interference such an innovative design for pusher assemblies can impact the retail market by integrating a pusher assembly 40 140 with the shipping carton and allows the product to go directly to the store shelves without manually restocking every package once one end of the carton is opened the entire carton of product can be placed onto the shelf and automatically dispensed as.
