Self-closing lid for cup
View Patent ↗A lid for container that can be open manually but closes itself automatically, The lid can he made out of plastic, paper or metal but preferably it should be made out of plastic. Along the lid lateral side, there is an item attached firmly on the lid and acting like a spring. This spring features an extension on the end not connected to the lid that acts as a button. Additionally, for usage, the lid is manually equipped with a flexible moving piece of material that can be made out of various material but preferably out of paper. This flexible piece of material will have a cut on one end that will be used to insert the button through in such a way that after insertion, the spring, the button, and the moving tongue move simultaneously. In order to use the assembly, the user needs to exert a pressure on the button with a finger, so that the spring gets under pressure and the moving piece of material moves along the surface of the lid to reveal the opening. As soon as the pressure on the button is removed, the spring gets back to its resting position along with the moving piece of material that covers the opening once again.
1. A lid assembly for enclosing and protecting content of a container that is used to consume beverages or food by an individual comprising;
a lid with a planar surface on its exterior side featuring an opening that allows the content to escape the container; a moving tongue;
an upper protrusion on said planar surface of said lid that increases in height gradually along a diameter of said planar surface and said upper protrusion features a delimited space for said moving tongue to be placed upon the said upper protrusion in such a manner that it is possible to slide said moving tongue seamlessly along said upper protrusion and keep said moving tongue within the delimited space;
a spout located at an uppermost end of said planar surface of said upper protrusion defining an inner space and having an upper hole, a bottom hole configured to communicate with a container, and a slot adjacent said planar surface communicating with said inner space;
said moving tongue being configured to slide along said planar surface and into said inner space through said slot to cover said bottom hole;
a lateral protrusion on a lateral edge of said lid adjacent a lowermost end of said planar surface;
a spring connected to said lateral protrusion at a first end and having a button extending laterally from a second end, said spring configured to extend vertically when pressure is applied to said button;
wherein said moving tongue is securely connected to said button such that when said pressure is applied to said button the moving tongue is displaced from covering said bottom hole to allow content to flow out of the container through said upper hole.
