Integrated device for opening and closing cans with deformation-resistant can lids

Abstract

An integrated device for opening and closing of cans and tins with a non-deformable partial lid to allow partial emptying of its contents and subsequent closing of a container, with a partial lid to be taken off as an integral part of the container's lid, delimited the partial lid by a circumscribing scoring line and with a lever for the opening of the partial lid joint together with the lid by centered riveting or similar known technique, where the lever includes a riveting end provided with a tear-off extension presenting a fold towards the lid whereas the other end includes a handgrip with an upper covering of the partial lid and a partial lid including two connections towards the lid of the container and presenting a non-deformable surface.

         11 . An integrated device for opening and closing of cans and tins with a non-deformable partial lid to allow partial emptying of its contents with subsequent closing of a container, with a partial lid detachable as an integrated part of a container's lid, of this container, delimited the partial lid by a circumscribing scoring line and with a lever for the detachment of the partial lid joint together with the lid by centered riveting, wherein the lever comprises a riveting end that comprises a surface of the centered riveting in the same piece, provided with a tear-off extension of the lever and presenting a fold towards the lid, while that the opposite end includes of a handgrip with an upper covering of the partial lid, wherein the opposite end and the rest of the body of the lever are joined together to the surface of the lid of the container by centered riveting, and the lever comprises a connection between the riveting end and the opposite end of the handgrip in a lengthways manner, of the same piece in shape of two non-deformable lateral crosspieces before the applied force tearing off the partial lid as they form longitudinal coating braces for reinforcement, with a die-cut in them, forming transverse folding shafts at their ends connected with the end of the handgrip, and with a partial lid including two connections towards the lid of the container and comprising a non-deformable surface. 
     
     
         12 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the lever includes a tear-off extension between the two non-deformable lateral crosspieces with three free sides and the fourth in connection with the end of the hand grip, the side opposite to it having, at its end, a transverse and perpendicular fold towards the scoring line of the lid of the container. 
     
     
         13 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the lever comprises an end of the hand grip as a connection to a tear-off extension and the two non-deformable lateral crosspieces, of the same piece, which has a larger diameter than the surface of the oval below it and surrounding the scoring line of the latter. 
     
     
         14 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the lever has transverse folding shafts on the side of the tear-off extension with the connection of the end of the hand grip and the ends of the two non-deformable lateral crosspieces with the end of the hand grip. 
     
     
         15 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the end of the handgrip of the lever comprises a protuberance at the upper surface for a grip of the fingers during its vertical movement. 
     
     
         16 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the end of the handgrip of the lever comprises a sealing washer of semi-soft material on the lower surface of the upper covering of the partial lid with a larger diameter compared to its diameter in order to achieve a tight closure. 
     
     
         17 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the partial lid has a scoring line surrounding it being in fixed connection with the rest of the lid of the container through two parallel interruptions on the centered side of this line of the lid with the centered riveting that presents lateral shaft of the partial lid's fold towards its vertical position. 
     
     
         18 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the partial lid is provided with a longitudinal central brace which guarantees its non-deformability in its lifting to a vertical position by means of the force exerted on the fold of the tear-off extension to its lower surface. 
     
     
         19 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , wherein the fold towards the lid is non-deformable due to a longitudinal brace of the fold cutting with its cutting edge of the fold the scoring line of the partial lid located between the two parallel interruptions because of a smaller width than the distance between the interruptions and due to the transverse angle with respect to the body of the lever towards the lid of the container. 
     
     
         20 . The integrated device for opening and closing of cans and tins with a non-deformable partial lid, according to  claim 11 , characterized by the fact that the fold detaches and lifts the partial lid to a vertical position with its inner side by manually lifting the lever progressively with the side of the end of the hand grip to a vertical position.
