My New Favorite Old Medicine Bottle

This is a Milk of Magnesia Medicine Bottle measuring 7" x 3" x 2.5". In block letters it says Milk Of Magnesia and in the middle of the three words it has a Trade Mark symbol in a circle, but I do not know what the symbols are called. Under that it says The Chas. H. Phillips Chemical Company Glenbrook, Conn. Side seams are catty corner and do not go over the lip. The bottom has K-929 on one side and a 4 on the other. The middle says U.S.A. and the Hazel Atlas symbol of an A inside an H. The bottle is a light shade of cobalt blue. Would appreciate if someone could date this for me, I am thinking maybe 1934? Thanks for stopping by.
