Claims
- 1. A push-pull dispenser for resealably closing a container, comprising:
- a tubular skirt having an inner and outer surface, the inner surface being sized to receive a container neck, and having a liquid tight longitudinally adjustable engagement means with the container neck, whereby the tubular skirt can longitudinally traverse the container neck from an upper, open position to a lower, closed position;
- a cylindrical plug disposed within the tubular skirt being sized to engage and seal the container neck, the perimeter of the cylindrical plug and the inner surface of the tubular skirt defining an annular orifice; and
- at least one spoke connector bridging the annular orifice and rigidly joining the cylindrical plug to the tubular skirt so that the cylindrical plug is substantially fixed in relation to the tubular skirt, the at least one spoke connector having an integrally molded brace.
- 2. The push-pull dispenser as claimed in claim 1, wherein the tubular skirt, the cylindrical plug and the at least one spoke connector are integrally molded from plastic.
- 3. The push-pull dispenser as claimed in claim 1, further including a dust cover comprising a top and a depending annular skirt sized to received and engage the push-pull dispenser.
- 4. The push-pull dispenser as claimed in claim 3, wherein the depending annular skirt of the dust cover has an inwardly extending annular flange which is spaced apart from a lower end of the annular skirt and which engages a corresponding outwardly extending annular flange on the outer surface of the tubular skirt, so that the dust cover can be snapped onto the push-pull dispenser.
- 5. The push-pull dispenser as claimed in claim 3, wherein the annular skirt of the dust cover further includes a depending frangibly connected tamper evident band capable of engaging a locking lug on the container neck.
- 6. The push-pull dispenser according to claim 1 wherein the inner surface of the tubular skirt lacks threads for engaging the container neck.
- 7. The push-pull dispenser according to claim 1 wherein the engagement means includes an engagement surface comprising a smooth-walled cylinder.
- 8. The push-pull dispenser according to claim 7 wherein the engagement surface is threadless and grooveless.
- 9. The push-pull dispenser of claim 1 wherein the cylindrical plug includes an outer cylindrical sidewall.
- 10. The push-pull dispenser of claim 9 wherein the outer cylindrical sidewall is insertable into a cylindrical neck inner wall.
- 11. A push-pull dispenser for resealably closing a container, comprising:
- a tubular skirt having an inner and outer surface, the inner surface being sized to receive a container neck, and having a liquid tight longitudinally adjustable cylindrical engagement wall engagable with the container neck, the tubular skirt capable of only longitudinally moving relative to the container neck from an upper, open position to a lower closed position;
- a cylindrical plug disposed within the tubular skirt sized to engage and seal the container neck, the perimeter of the cylindrical plug and the inner surface of the tubular skirt defining an annular orifice; and
- at least one spoke connector bridging the annular orifice and rigidly joining the cylindrical plug to the tubular skirt so that the cylindrical plug is substantially fixed in relation to the tubular skirt, the at least one spoke connector having an integrally molded brace.
- 12. The push-pull dispenser of claim 11 wherein the tubular skirt projects above the cylindrical plug.
- 13. The push-pull dispenser according to claim 11 wherein the inner surface of the tubular skirt lacks threads for engaging the container neck.
- 14. The push-pull dispenser of claim 11 wherein the cylindrical plug includes an outer cylindrical sidewall that is insertable into a cylindrical neck inner wall.
- 15. The push-pull dispenser as claimed in claim 11 further including a dust cover comprising a top and a depending annular skirt sized to received and engage the push-pull dispenser.
- 16. The push-pull dispenser as claimed in claim 15, wherein the depending annular skirt of the dust cover has an inwardly extending annular flange which engages a corresponding outwardly extending annular flange on the outer surface of the tubular skirt, so that the dust cover can be snapped onto the push-pull dispenser.
- 17. The push-pull dispenser as claimed in claim 15, wherein the annular skirt of the dust cover further includes a depending frangibly connected tamper evident band capable of engaging a locking lug on the container neck.
