Metallic package

Abstract

A package comprising a metallic container having a mouth portion and a metallic cap with a liner fitted to the mouth portion, wherein the liner 17 of the cap includes an outer ring 20 hanging down from an outer circumferential end thereof and an inner ring 21 hanging down on the inside of the outer ring 20 ; the inner surface of the outer ring 20 extends straight in the vertical direction; and a corner portion from the top panel to the skirt is draw-formed while pushing the cap from the upper direction in a state where the open end of the container mouth portion is inserted, so that the inner surface of the outer ring is brought into close contact with the outer surface of the side wall portion formed at the open end of the container mouth portion, an inner protruded portion is formed at the lower end of the inner surface of the outer ring so as to protrude inward, and the inner protruded portion is brought into close contact with the outer side portion of the lower curled portion of the container mouth portion. The package effectively prevents the breakage of the sealing before the breakage of the bridge that connects the TE band, and can be favorably resealed.

1 . A package comprising a metallic container having a mouth portion and a metallic cap fitted to the mouth portion, an open end of the mouth portion of the metallic container including an upper curled portion formed at an upper end thereof, a side wall portion hanging down vertically from the upper curled portion and a lower curled portion extending inward from a lower end of the side wall portion, the metallic cap including a top panel, a skirt hanging down from a circumferential edge of the top panel and a plastic liner adhered and fixed to the inner surface of the top panel, and at a lower end of the skirt, a tamper evident band being formed via a breakable bridge, wherein:
 the liner of the metallic cap includes an outer ring hanging down from an outer circumferential end thereof and an inner ring hanging down on an inside of the outer ring;   an inner surface of the outer ring extends straight in the vertical direction; and   in a state where the metallic cap is placed on the mouth portion of the container and the open end of the mouth portion is inserted in a space between the outer ring and the inner ring, a corner portion from the top panel to the skirt is draw-formed while pushing the cap from the upper direction so that an inner surface of the outer ring is brought into close contact with an outer surface of the side wall portion formed at the open end of the mouth portion of the container, an inner protruded portion is formed at an lower end of the inner surface of the outer ring so as to protrude inward, and that the inner protruded portion is brought into close contact with an outer side portion of the lower curled portion of the mouth portion of the container.   
   
   
       2 . The package according to  claim 1 , wherein in the outer circumferential edge portion of the liner, a region that does not adhere to the inner surface of the top panel is formed. 
   
   
       3 . The package according to  claim 1 , wherein the inner protruded portion is protruding inward over a length of 0.03 to 0.65 mm beyond the outer surface of the side wall portion. 
   
   
       4 . The package according to  claim 1 , wherein a surface between the lower end of the inner surface of the outer ring and the lower end of the outer surface of the outer ring is forming a tapered surface being tilted downward from the inner surface side thereof toward the outer surface side thereof. 
   
   
       5 . The package according to  claim 1 , wherein a recessed portion is formed in the surface positioned between the outer ring and the inner ring of the liner at either a portion positioned on the inner ring side or a portion positioned on the outer ring side in a state before the mouth portion of the container is wrap-seamed with the cap. 
   
   
       6 . The package according to  claim 4 , wherein the tapered surface between the lower end of the inner surface of the outer ring and the lower end of the outer surface of the outer ring is titled at an angle θ of 10 to 70 degrees with respect to the horizontal plane. 
   
   
       7 . The package according to  claim 1 , wherein a gap is formed between the outer circumferential surface of the outer ring and the skirt at a position at least on the outer side of the lower portion of the side wall portion in the direction of diameter thereof.
