The Dacro Crown 
Makes an hermetically sealed milk bot- 
tle possible—insures continued cleanli- 
ness after filling and crowning—facili- 
tates transportation and refrigeration— 
makes tampering with the contents of the 
bottle impossible without immediate de- 
tection by dairyman or consumer—pro- 
vides a seal, which, after its initial re- 
moval from the bottle, is sufficiently in- 
tact for use as an odor proof temporary 
covering for the bottle while any portion 
of its contents remains—deters bacterial 
development — permits the accomplish- 
ment of pasteurization within the bottle.
