PART IV. 

 FROM FACTORY TO CONSUMER 



CHAPTER XVI. 



Stamping. Every well regulated condensing' factory, selling 

 condensed milk in hermetically* sealed tin cans, employs some 

 system of marking the cans. This is important for future 

 reference. 



When defective condensed milk is returned to the factory, 

 the marks on the cans tell the manufacturer the date of manu- 

 facture, and his own record on file in the factory shows the con- 

 ditions under which the defective milk was rnade.^ In this way 

 defects can usually be traced to their causes and the recurrence 

 of similar trouble can be avoided. 



In some factories the batches of condensed milk are num- 

 bered from one up, and the cans are stamped with the respective 

 batch number. This method is simple but may prove undesirable, 

 since it informs the competitors also of the date of manufacture 

 of competing brands. In most factories a code of letters and 

 figures is used, designating the factory, the date, and the number 

 of the batch of each day. 



The cans are 

 usually stamp- 

 ed on the bot- 

 tom, that is, on 

 the end which 

 carries the cap. 

 The stamping 

 is done by the 

 sealer. Small 

 interchangeable 

 rubber letters 

 and figures are
