 The original notion of lemon juice being packaged inside lemon @-@ shaped and coloured containers was the brainchild of Edward Hack in the 1950s . Bill Pugh , an English plastics designer , created a prototype based upon Hack 's concept . The company Edward Hack , Ltd. then produced and marketed Hax brand lemon juice in the plastic containers , using juice from Sicily . Stanley Wagner of Coldcrops , Ltd. also independently designed a very similar package , which was used for Realemon brand lemon juice . Realemon was later renamed to ReaLem by Coldcrops . Hax lemon juice was the first to be packaged and marketed in said lemon @-@ shaped container , with Coldcrops following shortly thereafter . A later agreement between Hax and Coldcrops led to Hax leaving the lemon juice business , whereby Coldcrops acquired the marketing rights for lemon juice in plastic lemon containers under the ReaLem brand . Coldcrops was acquired by Reckitt and Colman in 1956 , which rebranded the product under the Jif brand name .
