Who invented tea bags?

During the Tang Dynasty (618-907), in China, paper was folded and sewn into square bags to preserve the flavor of tea. The first Western tea bags were hand-sewn fabric bags; tea bag patents date as early as 1903. First appearing commercially around 1904, tea bags were successfully marketed by the tea and coffee shop merchant,  Thomas Sullivan from New York, who shipped his tea bags around the world. The tea in loose form was intended to be removed from the sample bags, but the customers found it easier to brew the tea in cups still enclosed in the bags. These days tea bags are usually made of paper fibre. The heat-sealed  paper fiber tea bag was invented by William Hermanson, one of the founders of Technical Papers Corporation of Boston. The rectangular tea bag was not invented until 1944. Prior to this, tea bags resembled small sacks. 

Who invented drinking cup?

As the drinking cup existed before the recorded history, hence the original inventor of the drinking cup is not known. The drinking cup would have been a  improvement over drinking liquids with cupped hands. Different types and examples of drinking cups have been found dating in very early history. Pre-historic cups could be made from a variety of materials like shells, animal horns, carved rocks, hollowed out gourds and even skulls. More modern cups were made out of various types of wood, paper, glass and different types stones available in various places.

How and when Cups and Glasses were invented?

In ancient times, man used hollow horns of animals, hard shells of vegetables, coconuts, eggshells and even a skull as a vessel. This went on till the third century when the art of glass making was developed in Rome. Now cups and glasses were made of glass. However, with the fall of the Roman Empire, this art was buried in the pages of history. In the 16^th century, Europeans revived the art of glass making. These cups and glasses could not be used in the local market because they broke when exported. To overcome this problem, large tin glasses with a handle were developed in America. These glasses were quite handy. In the 17^th century, glasses of animal hide were made. These were made by stitching the smoothened hide of animals and fixed with silver lace on all sides. Then came wooden glasses. In India, disposable glasses and cups of clay were also quite popular. The importance of disposable glasses was acknowledged during times of epidemic. In 1908, inexpensive paper cups and glasses flooded the market and are still quite popular all over the world, thereafter replaced by plastic and thermacol.
