According to the US Patent & Trademark Office, this bottle design was patented in 1927 by a Samual C. Miller. You can see the original patent and specifications by going to http://patft.uspto.gov/netahtml/PTO/srchnum.htm and putting in D73096 into the search box.
The phrase " Federal law forbids sale or reuse of this bottle" did not come into use until 1935, so your bottle was definitely made after that point. You might be interested in looking at the website:http://www.blm.gov/historic_bottles/machinemadedating.htm#Question%2010 to see if it provides any clues in dating your bottle. It could be a reproduction of an older bottle as well.
