Every morning I go out for a cup of coffee and a bagel. By the time I get to my office, the coffee has leaked out of the top of the coffee container, soaked the napkins and made the bagel all soggy. To solve this problem I decided to invent a beverage cup lid that doesn’t leak.

My solution to stop the leak from the small vent hole on the top of the lids is to apply a proprietary filter material, which allows air to flow through the vent hole, while retaining the liquid inside the container. The vent hole can be anywhere on the lid and the filter material can be fabricated in a variety of colors.

This invention will prevent unwanted release of hot or cold liquid, which has the ability to burn the user or create an unsanitary and messy condition. In the case of a hot coffee spill, clothing, furniture, carpeting, car interiors and any surrounding surfaces may be stained, any other contents of the soggy bag are typically soaked and spoiled. Moreover, hot coffee and the like can cause scalding as it is ejected out of the container upon impact leaving the vendor open to liability.
