Abstract
Abstract A bottle cap of inverted concave shape in its cross section made of blank material of synthetic resin of high resiliency such as polyethylene or the like, wherein a horizontal, raised recess is formed on the center surface of the cap, and a bottle opening abutting channel is defined by the periphery of the cap and the wall of the recess on the backside of the cap, and projecting strips are provided integrally with the inner wall of the periphery at the base side of a tongue projecting from and secured to the periphery at right angle thereto and at the opposite side to the base on the backside of the periphery, cutout portions are formed on opposite sides of the projecting strips, said cut-out portions extending to the depth adjacent to the cap periphery, and small projecting strips encompassing the backside wall of the recess are provided.

Claim 1
Independent Claim
383 words
A bottle cap structure comprising a circular planar central panel; a first cylindrical wall having top and bottom ends, said bottom end being circumferentially joined to said centraL panel, and said wall extending uprightly upwardly from said panel; an annular member having inner and second outer peripheries, the inner periphery being integrally joined to the top end of the said cylindrical wall and extending radially outwardly therefrom; a second cylindrical upright wall having top and bottom edges, said top edge of said second cylindrical wall being integrally joined at said top edge to the second outer periphery of said annular member and said upright wall extending downwardly from said annular member and terminating at a location spaced below the plane of said central panel; and a planar radially outwardly extending tongue integrally joined to the second cylindrical wall at its bottom edge; said first and second cylindrical walls and said annular member together forming a bottle-mouth receivingchannel; said first cylindrical wall having an integral radially outwardly projecting sealing rib disposed in spaced parallel relationship to said annular member and extending about the full circumference of said wall; said annular member having a continuous downwardly projecting sealing rib disposed in parallel spaced relationship to both of said first and second cylindrical walls; said second cylindrical wall having inner and outer surfaces and having integral radially inwardly projecting locking ribs disposed circumferentially on the inner surface in a plane parallel to and spaced from both said annular member and the bottom edge of said second cylindrical wall, one of said locking ribs being disposed with its longitudinal center diametrically opposite the center of said tongue with said locking rib extending substantially 180* along the inner surface of the second cylindrical wall, and the other of said locking ribs being disposed on the portion of the second cylindrical wall adjacent said tongue with its terminal ends disposed substantially symmetrically relative to the side edges of said tongue and with said ends horizontally spaced less than the horizontal space of said edges; and said second cylindrical wall being provided on its inner surface with an axially-extending groove at each terminal end of the locking ribs with each said groove extending from the bottom face of the annular member to the bottom edge of the second cylindrical wall.
