Easily openable can lid
View Patent ↗A can lid of a can provided with an easily openable opening means is disclosed wherein the can lid is equipped with a can lid which is fastened by winding tightly on the can main body and the top end opening of the can main body, a score section installed around the territory of the prearranged opening area and a tab for severing the score section. In the can lid, there is formed a protrusion protruding upward from the can lid in front of the can opening during manufacturing of the can lid, in which it is a collapsing protrusion where the protrusion elastically deforms into the can main body by depressing motion of the user and thereby enables forming of a concave section for easy insertion of the user's finger.
1. An easy-opening can end comprising an end panel, a score line in said end panel definding an openable panel portion; a pull tab defined by a nose, a handle and a medial portion between said nose and handle; means for securing said medial portion to said end panel with said nose adjacent said score line, said end panel including a convexly upwardly projecting protrusion underlying and contiguous said handle, and means definded by the material of said protrusion of elastically deforming said convexly upwardly projecting protrusion to an upwardly concavely opening and downwardly projecting protrusion upon the application of a downwardly directed manually applied force to said convexly upwardly projecting protrusion to form a gap between said handle and said elastically deformed upwardly concavely opening protrusion incident to severing said score line by imparting a lifting force to said handle.
2. The easy-opening can end as defined in claim 1 wherein said handle overlies said upwardly convexly projecting and upwardly concavely opening protrusion incident to imparting a lifting force to said handle.
3. The easy-opening can end as defined in claim 2 wherein said handle is contiguous said upwardly convexly projecting protrusion and defines a finger gripping gap with said protrusion in the upwardly concavely opening configuration thereof.
