The invention provides oleocanthal analogs and methods of using oleocanthals in various formulations including, food additives; pharmaceuticals; cosmetics; animal repellants; and discovery tools for mammalian irritation receptor genes, gene products, alleles, splice variants, alternate transcripts and the like. A plurality of repeaters can be provided in the system as the overall system expands when additional first and second devices, such as master units and control devices, are added. The interior portion has perforations that absorb accelerations, such as a perforations formed around the outside perimeter of the location at which a product rests, perforations extending from corners of the support surface towards a central location of the support surface, and perforations at the scoring of the tabs.
