The bottles are called Dripless milk bottle. Due to the wide lip on a milk bottle they were prone to drips running down the side of the bottle. On October 3, 1933, Carl Swanson of Minneapolis, Minnesota patented a design for an antidrip milk bottle. His bottle had a series of indents around the neck, similar to a honeycomb. The idea was that this would stop the drip from moving downwards and increase the surface area so it would dry. Unfortunately this design was hard to clean, weakened the glass in the neck area of the milk bottle and was difficult to remove from the mold during manufacture. Swanson was granted a second patent on August 27, 1935 that addressed these issues. This bottle had a pattern of embossing on the neck that looked like brickwork. The lines, however, were above the surface of the glass so the neck was not weakened. This design was easier to clean and also inhibited the downward movement of drips. The horizontal lines tended to spread out the drip letting it dry faster. I am still un sure if it was only for milk bottles - and when the indents began to appear near the bottom of the bottles. However, it is a start.
