Claims
- 1. A container closure comprising:a shell adapted to be attached to a container around a container opening thereof, said shell having a shell opening adapted to be in fluid communication with the container opening when said shell is attached to the container and an annular wall surrounding said shell opening; a tip slide-able on said shell movable between a closed position sealing said shell opening and an open position, said tip includes a pair of sleeve members positioned adjacent said annular wall and each sleeve member having at least one member extending radially from said sleeve member and in sliding engagement with said annular wall during the entire movement between the closed and the open position; and a cover releasably attached to said shell, said cover indicative of said tip being positioned in said closed position when said cover is attached to said shell.
- 2. The container closure of claim 1 wherein said cover includes a tamper-evident band removably attached as a portion thereof.
- 3. The container closure of claim 2 wherein said cover further includes a top, a cylindrical side extending from said top, wherein said tamper-evident band is formed by a lower portion of said cylindrical side, and at least one projection extending radially inwardly of said side configured to at least initially attach said cover to said shell.
- 4. The container closure of claim 1 wherein said shell further includes at least one stop extending radially from said annular wall and adapted to abut against one said member of one said sleeve member of said tip to limit movement and resist removal of said tip relative to said shell in one direction.
- 5. The container closure of claim 1 wherein said shell includes a central stem, and said shell opening is an annular opening surrounding said stem.
- 6. The container closure of claim 5 wherein said shell further includes an annular ring surrounding and spaced from said annular wall, and at least one projection extending radially outwardly on said annular ring.
- 7. The container closure of claim 5 wherein said tip includes a tip opening in fluid communication with said shell opening when said tip is in said open position, and an annular stem-sealing member surrounding said tip opening, said stem-sealing member in sealing engagement with said stem when said tip is in said closed position.
- 8. The container closure of claim 5 wherein said shell further includes a plurality of bridging elements extending across said annular opening between said stem and said annular wall to secure said stem to said annular wall.
- 9. The container closure of claim 5 wherein said shell further includes a substantially cylindrical body portion extending from said annular wall, a means for attaching said shell to the container formed on said cylindrical body, and a tamper-evident band extending from said cylindrical body.
- 10. The container closure of claim 9 wherein said shell further includes a sealing ring attached to said cylindrical body, said sealing ring adapted to seal against the container round the container opening when said shell is attached to said container.
- 11. A container closure comprising:a shell adapted to be attached to a container around a container opening thereof, said shell having a shell opening adapted to be in fluid communication with the container opening when said shell is attached to the container; a tip received on said shell movable between a closed position sealing said shell opening and an open position; and a cover releasably attached to said shell, said cover indicative of said tip being positioned in said closed position when said cover is attached to said shell, wherein said cover includes a tamper-evident band removably attached as a portion thereof, a top, a cylindrical side extending from said top, wherein said tamper-evident band is formed by a lower portion of said cylindrical side, and at least one radially extending ear on the outer surface of said cylindrical side, said shell further including at least one outer stop member engageable with said radially extending ear.
- 12. A container closure comprising:a shell adapted to be attached to a container around a container opening thereof, said shell having a central stem and an annular shell opening surrounding said stem and adapted to be in fluid communication with the container opening when said shell is attached to the container, wherein said shell further includes an annular wall surrounding said annular opening and a cover-attaching member positioned on said stem formed by a groove on said stem; a tip received on said shell movable between a closed position sealing said shell opening and an open position; and a cover releasably attached to said shell, said cover-attaching member adapted to engage said cover to releasably attach said cover to said shell whereby said cover is indicative of said tip being positioned in said closed position when said cover is attached to said shell.
- 13. The container closure of claim 12 wherein said tip is slidably received on said shell and said tip includes at least one sleeve member positioned adjacent said annular wall and at least one ring-sealing member extending from said sleeve member and in sliding engagement with said annular wall.
- 14. The container closure of claim 13 wherein said tip includes two of said sleeve members, including an inner sleeve member positioned radially inwardly of said annular wall, an outer sleeve member positioned radially outwardly of said annular wall, and a grippable ledge extending radially outwardly from said outer sleeve member.
- 15. A container closure comprising:a shell adapted to be attached to a container around a container opening thereof, said shell having a central stem, an annular opening surrounding said stem and an annular wall surrounding said annular opening, wherein said stem extends above said annular wall; and a tip slidably received on said stem, said tip including an opening and a stem-sealing member surrounding said opening, said tip moveable between an open and a closed position, wherein said tip includes an inner sleeve member positioned radially inwardly of said annular wall and an outer sleeve member positioned radially outwardly of said annular wall, and wherein each said sleeve member includes a ring sealing member extending from said sleeve member and in sliding engagement with said annular wall.
- 16. The container closure of claim 15 wherein said tip includes a grippable ledge extending radially outwardly from said outer sleeve member.
- 17. The container closure of claim 15 wherein said shell further includes an annular ring surrounding and spaced from said annular wall, and at least one projection extending radially outwardly on said annular ring.
