Publication number: 20240206936Abstract: At parties and other social gatherings, drinks are typically served in non-descript glassware. As a result, patrons may be unable to distinguish their glass from others once they are set down on a table.

To solve these problems, the inventors have created an easy way for people to mark their glassware with individualized stickers that are easy to remove at the conclusion of a gathering. These water-soluble stickers can be designed around the theme of the gathering. Guests select from a set of unique stickers and adhere one to their glasses - they work on all glassware (even without stems). At the end of the gathering, the host can easily remove the drink markers by running the glassware under water or by placing them in the dishwasher as they normally would.Type: ApplicationFiled: January 26, 2024Publication date: June 27, 2024Applicant: Glass Tats LLCInventors: Maya Pacheco, Corinne Golden
