Lid for a drinking container and the drinking container

Abstract

A lid for a drinking container includes a circular upper portion including a bayonet fastening device, and a circular lower portion including a counterpart bayonet fastening device. The circular upper portion includes a first and second openings and the circular lower portion includes corresponding first and second openings. The bayonet fastening device of the circular upper portion and the counterpart bayonet fastening device of the circular lower portion are configured to be coupled with each other so 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. In addition the invention relates to a method for manufacturing the lid for the drinking container as well as to a drinking container comprising or using the lid.BACKGROUND OF THE INVENTION[0002]Numbers of different lid for drinking containers are known, where one of the simplest one is a plastic flat lid having a small drinking hole on the top cover area and a bent rim portion, which is to be settled around the rim portion of a cardboard coffee mug. Also rubber lids are known, where the drinking hole is sealed with a sealing member. The sealing member has typically a small arm and is hinged so that it can be turned away from the drinking hole for drinking the liquid inside the mug, and again it can be turned over the drinking hole for a sealing purpose. The sealing m...

AI Technical Summary

Benefits of technology

The invention is a lid for a drinking container that solves problems with previous lids. It is easy to use, keeps the drinking hole clear, and seals it tightly. The lid can be easily attached and detached from the container. It also provides a clear indication of its position. The lid comprises a circular lower portion with a fastening thread, sealing members, and a structural portion made of hard or softer material. The top surface of the circular upper portion may have a matte or rough outer surface for better user experience and grip. The invention offers a reliable way to close the drinking hole and prevent leaks or spills. It also simplifies the manufacturing process and is easy to use and keep clear.

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.
