Bottle Cap

Abstract

A cap for sealing a container having a neck includes an annular outer skirt having an inner surface and an outer surface, a top portion of the outer skirt forming an annular rim. A generally concave top wall extends inwardly from and below a plane defined by the rim, the top wall having a top face and a bottom face. An annular inner skirt extends downward from the top wall bottom face and disposed radially inward from and concentric with the outer skirt, wherein the inner skirt is configured to sealingly engage with an inner surface of the container neck when the cap is attached thereto.

         21 . A cap for a container comprising:
 a top wall comprising a top face, a bottom face, and an annular rim;
 an annular outer skirt attached to the bottom face of said top wall; 
 the top wall further comprising an annular inner skirt attached to the bottom face and adjacent to the outer skirt, to selectively engage a container; 
 the outer skirt further comprising an outer surface and an inner surface; 
 the inner surface further comprising a threaded pattern; and 
 the outer surface further comprising a pattern for enhancing grip. 
   
     
     
         22 . The cap of  claim 21 , wherein the inner skirt comprises:
 an outer edge that tapers toward the center of the top wall; and   an inner edge that is orthogonal to said top wall and contacts the outer edge at the terminus of the inner skirt.   
     
     
         23 . The inner skirt of  claim 21 , wherein the inner skirt further comprises an inner skirt surface that is orthogonal to the top wall and tapers toward the outer skirt surface. 
     
     
         24 . The cap of  claim 21 , further comprising a sealing ring in the annulus of the outer skirt and inner skirt for sealingly engaging a container. 
     
     
         25 . The cap of  claim 21 , wherein the pattern for enhancing grip is a plurality of parallel ribs. 
     
     
         26 . The cap of  claim 21 , wherein the threaded pattern is of a helical type for selectively engaging a container. 
     
     
         27 . The cap of  claim 21 , wherein the top face further comprises at least one indicia. 
     
     
         28 . The cap of  claim 21 , wherein the bottom face further comprises at least one indicia. 
     
     
         29 . The cap of  claim 21 , wherein the outer skirt is adjacent to the rim on the bottom face. 
     
     
         30 . A cap for a container comprising:
 a concave top wall comprising a top face, a bottom face, and an annular rim;   an annular outer skirt, including an inner and outer surface, attached to the bottom face of said top wall; and   an annular inner skirt, including an inner and outer surface, attached to the bottom face of the top wall.   
     
     
         31 . The inner skirt of  claim 30 , wherein the inner skirt further comprises an inner skirt surface that is orthogonal to the top wall and tapers toward the outer skirt surface. 
     
     
         32 . The cap of  claim 30 , wherein the outer skirt is adjacent to the rim. 
     
     
         33 . The cap of  claim 30 , wherein the inner skirt is adjacent to the outer skirt. 
     
     
         34 . The cap of  claim 30 , wherein the top face further comprises at least one indicia/logo. 
     
     
         35 . The cap of  claim 30 , wherein the bottom face further comprises at least one indicia/logo. 
     
     
         36 . The cap of  claim 30 , wherein said inner skirt comprises an inner and outer surface, the inner surface being tapered toward the outer surface opposite of the attachment to the bottom face. 
     
     
         37 . The cap of  claim 30 , wherein the outer skirt further comprises a threaded pattern on the inner surface. 
     
     
         38 . The cap of  claim 30 , wherein the outer surface of the outer skirt further comprises a plurality of ribs for enhancing grip. 
     
     
         39 . The cap of  claim 30 , further comprising a sealing ring situated between the outer skirt and inner skirt for sealingly engaging a container. 
     
     
         40 . A cap for a container comprising:
 a concave top wall comprising a top face, a bottom face, and an annular rim;   a pair of concentric skirts on the bottom face, the pair comprising an outer skirt, along the perimeter of the annular rim, and an inner skirt; and   a sealing ring disposed in the annulus between the outer and inner skirts.
