old glass bottle found in back yard

I found it digging by home plate, which is in the northwest corner of the back yard.  It says DES PAT 98424, which was a bottle design patented in 1935. It could have held a chemical for killing pain smell or medicine, or maybe something else.  Who knows.  But it does seem old.  It was buried under the roots of the removed oak tree, which likely preserved it.

"Classic Oblong" style drug/chemical bottle - This commonly encountered bottle on mid-20th century historic sites is what the maker - the Owen-Illinois Glass Co. - called in their catalogs a "Classic Oblong" and listed in those catalogs "Drug & Chemical Containers" sections (Lucas County Bottle Co. 1940s; Owens-Illinois Glass Co. 1952; 1962).  This example is 5.5" tall, holds 4 oz., has an external screw cap finish, and made of colorless glass that is slightly straw colored indicating glass decolorization with arsenic and/or selenium.  Click side view to see such which has several staggered vertical ribs defining the edge of the side.  Click base view to see such which, although hard to read, is embossed with DES. PAT. / 94824 along with a mold number "2" (to left side of base) and the glass makers marking (the earlier "Saturn" marking) with an undecipherable plant number, but a likely "38" date code (to right side of base).  The base also shows some of the suction scar made by the Owens Automatic Bottle Machine.  The best way to understand the somewhat "Art Deco" design is to view the original Design Patent #94824 which was issued in 1935 to an (apparent) employee of the glass company.  The patent date along with the noted catalog information indicates this bottle was popular from 1935 until at least the early 1960s, this being an earlier example indicated by the 1938 date code.  (All of the later examples would also have date codes on the base, if decipherable.)  It is likely that these bottles were also used for other products like hair tonic, aftershave, and other toiletries.
