Benefits of technology

The invention provides a lid for a drinking container that is easy to use and keeps the container clear. The lid seals the drinking hole in a reliable way to prevent any unwanted opening. The lid also provides a clear indication to the user whether it is open or closed.

Problems solved by technology

Furthermore more complex structures are also known, such as lids with inner sealing members having e.g. springs and sealing balls, where the balls are pushed by the springs into and away from the drinking hole for example when the lid is turned around.
There are however some disadvantages relating to the known prior art, such as the plastic flat lid having a small drinking hole does not have any sealing function for the drinking hole.
In addition the rubber lid with the sealing member is not tight enough because the spring force of the arm is often loosen and especially because the small arm is easily bent or even swing away from the hole area, for example when the mug is put into a bag.
Furthermore lids with inner sealing members having e.g. springs and sealing balls are very complex to manufacture and additionally extremely difficult to keep clean, and often there is also no clear feedback or indication to the user when the lid is in an open or closed position.

Abstract

A lid for a drinking container includes a circular upper portion having a groove portion extending on the circumference of the circular upper portion, and a circular lower portion having a counterpart groove portion extending on the circumference of the circular lower portion. The circular upper portion includes first and second openings and the circular lower portion includes corresponding first and second openings. The groove portion of the circular upper portion and the counterpart groove portion of the circular lower portion are configured to be coupled with each other to guide the circular upper portion and the circular lower portion to be turned in relation to each other around a common axis in a manner enabling the first openings being aligned and the second openings being aligned in an opening position, and enabling the first openings being un-aligned and the second openings being un-aligned in a closing position.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention relates to a lid for a drinking container, such as especially a lid for a coffee or tea mug for preventing any leaking or spilling of liquid contained the mug in use.
