This seal is reasonably strong and usually hermetically tight. The chief advantages of the seals without solder lie in the saving of labor, and the reduction of the cost due to the omission of solder. The principal reason for which some of them are not used more generally by milk condensing companies, lies in the fact that these solderless seals are all patented. In most cases the in\entors or patent holders are condensed milk manu- facturers. They refuse to sell their pa- tents at a reasonable price to other condenseries and they charge exor- bitant royalties for the use of their patents by their com])etitors. AA'ith the possible exception of the "Sanitary can," solderless seals are not as re- liable as solder seals. 'â .- .. ....,:â¢--;.â -' . / Fig. 36, Soldering stove Courtesy of Arthur Harris & Co.
