 Bill Pugh, the chief plastics designer at Cascelloid, based in Leicester, and former Royal Air Force pilot, created a prototype of the blown lemon-shaped plastic shaped container based upon Hack's idea sometime in the 1950s, as well as other types of blown containers. Pugh's experimented with the initial design until he was satisfied with its appearance. This plastic lemon product was then used for Hax lemon juice. Edward Hack, Ltd. produced and marketed Hax brand squeezable plastic lemon containers filled with two ounces of Sicilian lemon juice. Per Edward Hack, Ltd., the juice was unfiltered, had no water added to it, and contained a preservative to prevent spoilage. Retailers could purchase the product in packs of six bags that contained 12 squeeze packs each, totalling 72 units. Upon introduction to the marketplace, Hax juice and the plastic lemon design received some press coverage per the unique nature and newness of the design. The Hax logo used on Hax lemon juice dates back to at least 1935, at which time it was used in advertisements for Hax brand iodine pencils and Hax brand aspirin.
