 Over the course of a ten @-@ month period from mid @-@ 1955 to early 1956 more than six million of the plastic juice lemons were sold by Coldcrops . This initially began under the brand name " Realemon " , and then after an objection by the then Board of Trade , the name was changed to " ReaLem " and marketed with the slogan " juice in a jiffy " . The Board of Trade objected because it was perceived that Coldcrops was possibly passing off their product as the Realemon brand from the United States . During this same time period , Hax was marketing tomato ketchup and brown sauce in custom @-@ shaped plastic containers , for use on restaurant tables . After a long argument about plastic containers , the two companies agreed that they would not compete with one @-@ another , and Coldcrops took the marketing rights for plastic lemons under the ReaLem brand . Coldcrops would market ReaLem lemon juice and agreed to not enter other plastic container markets .
