Closure having expanded peripheral surface
View Patent ↗A closure includes a ribbed design wherein the ribs improve the ability to manually manipulate the closure and produce a distinctive aesthetic appearance. The new design allows improved manufacturing ability while reducing closure cost.
1. A closure comprising:
a top having an outside circumference defining a peripheral edge, said top further having an upper top surface and a lower top surface;
a skirt depending from said lower top surface defining in part a first circumferential exterior surface, said skirt having an outer skirt surface and an inner skirt surface, said outer skirt surface positioned inwardly of said peripheral edge, the spacing between an intersection of said outer skirt surface with said lower top surface and said peripheral edge defining an annular portion of said lower top surface;
a plurality of vertical segregated ribs depending downwardly from said annular portion of said lower top surface, said ribs having outside edges extending from points proximal said peripheral edge to inner edges, the inner edges extending upwardly therefrom and to the lower top surface of the top to thereby define exposed exterior surfaces of each rib on opposite sides thereof radially extending between said outside edges and inner edges, said outside edges forming a second circumferential external surface of said closure which is not contiguous and said inner edges being further defined as separated from and non-connecting to said outer skirt surface; and
a tamper evidencing band connected to said skirt through a frangible line of weakness.
2. The closure of claim 1 wherein an exterior surface of said tamper evidencing band does not extend radially outside the circumferential exterior surface defined by said skirt.
3. The closure of claim 1 wherein said skirt is dimensioned and configured to freely expand during ejection from a mold.
4. The closure of claim 1 wherein a connecting member extends between two or more of said ribs, said connecting member being spaced from said circumferential exterior surface defined by said skirt.
5. The closure of claim 4 wherein said connecting member comprises a back wall connecting the inner edges of said two or more ribs.
6. A closure comprising:
a top including a peripheral edge and an underside;
a skirt depending from the underside defining in part a circumferential exterior surface, the skirt including an outer skirt surface positioned radially inwardly of the peripheral edge;
the underside of the top including an annular portion extending between the peripheral edge and the outer skirt surface;
a plurality of radially extending vertical ribs depending downwardly from the annular portion having exposed exterior surfaces on opposite sides thereof, the ribs having an inner free edge depending downwardly from the underside of the top and being radially inwardly of the peripheral edge and spaced from and unconnected to the outer skirt surface; and
a connecting member extending between two or more of said ribs, said connecting member being spaced from said circumferential exterior surface defined by said skirt.
7. The closure of claim 6 wherein said skirt is dimensioned and configured to freely expand during ejection from a mold.
8. The closure of claim 6 wherein the rib does not extend outwardly from the peripheral edge.
9. The closure of claim 6 wherein the connecting member is a back wall connecting the inner free edges of two or more of the plurality of ribs.
10. A closure comprising:
a top including a peripheral edge and an underside;
a single skirt depending from the underside defining in part a circumferential exterior surface, said skirt having an outer skirt surface and an inner skirt surface, said outer skirt surface positioned radially inwardly of the peripheral edge;
the underside of the top including an annular portion extending between the peripheral edge and the outer skirt surface;
a rib depending downwardly from the annular portion, the rib having an inner free edge depending downwardly from the underside of the top and being radially inwardly of the peripheral edge;
wherein the inner free edge is spaced from and unconnected to the outer skirt surface; and container engagement structure on said inner skirt surface, said container engagement structure being dimensioned and configured for snap-on application to, and screw-off removal from a container neck finish.
