Section 270. Unlawful detention of milk cans

No person shall, without the
  consent of the owner or shipper, or his agent, use,  sell,  dispose  of,
  buy  or traffic in any can, irrespective of its condition, or the use to
  which it may have been applied, belonging to any dealer in or shipper of
  milk or cream in this state or which may be shipped to any town, village
  or city in the state, which can has the name or initials of such  owner,
  dealer  or  shipper  stamped,  marked or fastened thereupon, or wilfully
  mar, erase or change by re-marking or otherwise such name or initials.
    If any person, without the consent of such owner, dealer  or  shipper,
  or  his agent, uses, sells, disposes of, buys, traffics in or has in his
  possession or under his control any such can, it  shall  be  presumptive
  evidence  that such use, sale, disposal, purchase, traffic or possession
  is unlawful.
    Any such owner, dealer or shipper, or his agent, may  take  possession
  of  any  can  used  in  violation of this article wherever found, and if
  filled or partly filled with milk or cream,  and  the  person  in  whose
  possession  it  is found does not, when requested, immediately empty the
  same, such owner, dealer or shipper, or his agent, may  empty  the  same
  into  the  street  or elsewhere, and shall not be liable for damages for
  any act done pursuant to the provisions of this article.
