No. 2 (I92l) REMARKS ON CANNING 4I 



Here in India there are no recognized standards but the cans 

 vary according to the pleasure of the manufacturer. 



13. (a) In the case of sardines the French nomenclature is 

 adopted which is nominally based on the kilogram (2'2 lb.), 

 ordinary rectangular sardine tins being called ' quarters,' double 

 sized tins ' halves,' and so on. But the quarter tin varies very 

 largely in dimensions and capacity : some are 4^4" x 3" x l' or 

 13/^ cubic inches in capacity ; the ordinary ' quarters ' as made 

 in the Government Cannery are full 4%" x 3" x 1 " or I2^i cubic 

 inches in capacity, weighing 9 to 10 oz. according to the thickness 

 of plate but always containing full 7 oz. of fish ; the solderless cans 

 are of similar size and capacity. ' Halves ' may be only 4%" x 4"x 

 lli" over all, outside measurements, or considerably below 24 

 cubic inches capacity when the covers are fixed, and weigh 13 oz. 

 packed with about 10 oz. fish ; but American halves are stated to 

 be 4/^" X 3!/^" X 2" or 31/4 cubic inches capacity. These are not 

 made in the Government Cannery but their place is supplied by 

 simply increasing the depth of the ' quarter ' can which then holds 

 above I2 oz. of fish ; this is very economical in tin plate and solder ; 

 or flat cylindrical cans (see below) may be used measuring 4^" x 

 1-^A" over all, weighing I lb. packed and containing full 12 oz. and 

 up to 13 oz. of fish. A rectangular can measuring 6%" X 4^" x 

 1^/2" was provided for ' half ' tins, but is not in use being extra- 

 vagant in tin plate and solder as compared with contents. As is 

 shown by the above figures the Government Cannery tins give full 

 measure for the price charged. 



14. (b) Oval tifis are largely in use in Great Britain for herrings, 

 pilchards, etc., and a common size is 7" x 3^" x il^" outside 

 measurements ; a smaller tin, as made by the solderless plant 

 at the Government Cannery, is 6" x 3^4" x ll4' over all. A 

 British small tin for herrings nn sauces, such as tomato, measures 

 approximately 5" X 31^" x i^" outside over all. 



15. (c) Cylindrical flats may be of any desirable depth ; it is usual 

 in a small factory to keep the same diameter and to vary the 

 capacity by increasing the depth. For instance, in the Government 

 Cannery the dies used give a cylinder of 4^' diameter (similar to 

 a butter tin) with a depth of I^" : these are called (in the cannery) 

 12 oz. cans, since they hold full 12 oz. fish (mackerel ; rather more 

 of sardines which pack closer), and weigh gross just I lb. or over. 

 By simply adding to the depth, a can of the same diameter will
