Child-resistant can top

Abstract

The present invention may comprise a main tab, a tab shield, a rim, an interior rim guard, and a tab finger port. The invention may further comprise breakable connectors among the tab, tab shield, rim, interior rim guard, and other structures, such that breakage of the connectors indicates access to a container after preventing or inhibiting access to a container, such as a beverage can.

1 . A device for covering an opening formed in a first surface of a container, comprising:
 a covering member having an upper surface, a lower surface, a rim portion, said lower surface contacting a rim portion of a first surface of the container;   wherein the container has a longitudinally extending cylindrical surface and including a rim portion extending along the periphery of the first surface of the container;   the lower surface of the covering member having a recess for enclosing said rim of the first surface of the container;   wherein the container has a longitudinally extending cylindrical surface and including a rim portion extending along the periphery of the first surface of the container and a pivotal lever inside the periphery of the first surface of the container for opening the container;   a tab portion at least partially covering the pivotal lever, the tab portion comprising an opening for lifting the tab portion away from the pivotal lever;   a frangible seal securing the tab portion to another portion of the covering member;   an interior aperture formed through the covering member, the interior aperture situated between the tab portion and the rim portion of the covering member; and   a plurality of side apertures, each aperture situated on a side of the tab portion.   
     
     
         2 . The device of  claim 1 , wherein the device is formed as a single unitary structure. 
     
     
         3 . The device of  claim 2 , wherein the single unitary structure is made from one type of material. 
     
     
         4 . The device of  claim 3 , wherein the one type of material is plastic. 
     
     
         5 . The device of  claim 1 , wherein the frangible seal is integral with the tab portion. 
     
     
         6 . The device of  claim 1 , wherein the device is destructively detachable from the container. 
     
     
         7 . A combination of a device for covering an opening formed in a first surface of a can and a can for holding a beverage, comprising:
 A can, including, a top with a rim, a cylindrical body attached to said top at said rim, an orifice formed through said top, and a pivotal lever for operation by a user to open said orifice;   a covering member having an upper surface, a lower surface, a rim portion, said lower surface contacting a rim portion of a first surface of the container;   wherein the container has a longitudinally extending cylindrical surface and including a rim portion extending along the periphery of the first surface of the container;   the lower surface of the covering member having a recess for enclosing said rim of the first surface of the container;   wherein the container has a longitudinally extending cylindrical surface and including a rim portion extending along the periphery of the first surface of the container and a pivotal lever inside the periphery of the first surface of the container for opening the container;   a tab portion at least partially covering the pivotal lever, the tap portion comprising an opening for lifting the tab portion away from the pivotal lever;   a frangible seal securing the tab portion to another portion of the covering member;   an interior aperture formed through the covering member, the interior aperture situated between the tab portion and the rim portion of the covering member; and   a plurality of side apertures, each aperture situated on a side of the tab portion.   
     
     
         8 . The combination of  claim 7 , wherein the covering member is formed as a single unitary structure. 
     
     
         9 . The combination of  claim 8 , wherein the single unitary structure is made from one type of material. 
     
     
         10 . The combination of  claim 9 , wherein the one type of material is plastic. 
     
     
         11 . The combination of  claim 7 , wherein the frangible seal is integral with the tab portion. 
     
     
         12 . The combination of  claim 7 , wherein the covering member is destructively detachable from the can. 
     
     
         13 . The combination of  claim 7 , wherein the covering member comprises a finger hole. 
     
     
         14 . A device for restricting access to an opening formed in a first surface of a container, comprising:
 a covering member having an integrally molded body including an annular structure and a sidewall, wherein;   the annular structure includes a central void defined by an intermediate perimeter;   a tearable tab portion formed in the body of the integrally molded body with a frangible seal on either side of the tearable tab portion, such that the tearable tab portion breaks when an upward biasing force is applied to the tearable tab portion; and   the sidewall engages with a lip of the container to prevent axial displacement of the covering member until the tearable tab portion is removed.
