A closure and container combination provide a child resistant package. The closure has a top wall and a skirt depending downwardly from a peripheral edge of the top wall. The container has a bottom, a cylindrical sidewall extending upwardly from the bottom and an open top. An annular flange projects outwardly from the outer surface of the cylindrical sidewall of the container proximate the top of the container. This annular flange has a flexible tab and is positioned below the skirt when the closure and container are mated together. To remove the closure from the container, the flexible tab is pushed upwardly against the skirt thereby lifting the closure off of the container. The flexible tab prevents undesired access through the annular flange and provides leverage to aid removal of the closure. In addition, a child is inhibited by the inflexible flange from using his or her teeth or fingernail to pry open the closure from the container.

1. A child resistant package comprising:a container including a bottom wall and a sidewall extending upwardly from the bottom wall, an upper edge of the sidewall defining a mouth of the container;a flange projecting generally perpendicularly outward from the sidewall and extending substantially entirely around the container proximate the upper edge thereof and generally parallel to the bottom wall;a flexible tab portion of the flange projecting outwardly from the sidewall and being circumferentially aligned and generally contiguous with the flange proximate the upper edge of the sidewall; anda closure including a top wall and a downwardly depending skirt;wherein the closure is adapted to mate with the container and releasably engage the upper edge of the sidewall to thereby close the mouth of the container;wherein when the closure is mated with the container the skirt is juxtaposed to the flange on the container such that releasing the closure from the container commences initially with upward force on the tab portion to deflect the tab portion upwardly against the skirt and thereby release the closure from the container. 2. The package of claim 1 further comprising:a living hinge coupling the tab portion to the sidewall of the container. 3. The package of claim 2 wherein the sidewall is generally arcuate and the living hinge is generally linear. 4. The package of claim 1 further comprising:a pair of slits in the flange bordering the tab portion of the flange. 5. The package of claim 1 wherein the flange is generally inflexible, with the exception of the tab portion, so that a user can not dislodge the closure from the container with upwardly directed force thereon. 6. The package of claim 1 wherein the flange is in contact with the skirt when the closure and container are mated together. 7. The package of claim 1 further comprising:a circumferential bead on the closure; anda circumferential lip on the sidewall of the container whereby the bead and the lip provide an interference snap fit there between when the closure and container are mated together. 8. The package of claim 7 wherein the bead projects outwardly on the closure and the lip is on an interior surface of the sidewall to provide a seal between the closure and the interior of the container. 9. The package of claim 1 further comprising:an outer rim coupling the skirt to the top wall; andan annular space between the skirt and an outer perimeter of the top wall;wherein the upper edge of the sidewall is interposed within the annular space when the closure and container are mated together. 10. The package of claim 9 wherein the outer rim further comprises:a ridge projecting from the outer perimeter of the top wall; anda ledge projecting from the ridge and connected to the skirt. 11. The package of claim 1 wherein the closure and a cross section of the sidewall are each generally circular. 12. The package of claim 1 wherein an outer circumference of the flange is greater than an outer circumference of the skirt. 13. A child resistant package comprising:a container including a bottom wall and a sidewall extending upwardly from the bottom wall, an upper edge of the sidewall defining a mouth of the container;a flange projecting outwardly from the sidewall and extending substantially entirely around the container proximate the upper edge thereof;a flexible tab portion of the flange projecting outwardly from the sidewall and being circumferentially aligned and generally contiguous with the flange proximate the upper edge of the sidewall; anda closure including a top wall and a downwardly depending skirt;wherein the closure is adapted to mate with the container and releasably engage the upper edge of the sidewall to thereby close the mouth of the container;wherein when the closure is mated with the container the skirt is juxtaposed to the flange on the container such that upward force on the tab portion deflects the tab portion upwardly against the skirt to thereby release th e closure from the container;wherein the flange and the associated tab portion each project generally perpendicularly from the sidewall of the container. 14. The package of claim 1 further comprising:a rim coupling the skirt to the top wall;wherein the rim extends at an obtuse angle from the top wall. 15. A child resistant package comprising:a container including a generally circular bottom wall and an arcuate sidewall extending upwardly from the bottom wall, an upper edge of the sidewall defining a mouth of the container;a flange projecting generally perpendicularly outward from the sidewall and extending substantially entirely around the container proximate the upper edge thereof and generally parallel to the bottom wall;a flexible tab portion of the flange projecting outwardly from the sidewall and being circumferentially aligned and generally contiguous with the flange proximate the upper edge of the sidewall;a generally linear hinge coupling the tab portion to the sidewall of the container;a pair of slits in the flange bordering the tab portion;a closure including a top wall and a downwardly depending skirt;wherein the closure is adapted to mate with the container and releasably engage the upper edge of the sidewall to thereby close the mouth of the container;wherein when the closure is mated with the container the skirt is juxtaposed to the flange on the container such that releasing the closure from the container commences initially with upward force on the tab portion to deflect the tab portion upwardly against the skirt and thereby release the closure from the container;wherein the flange is generally inflexible, with the exception of the tab portion, so that a user can not dislodge the closure from the container with upwardly directed force thereon. 16. The package of claim 15 wherein the flange is in contact with the skirt when the closure and container are mated together. 17. The package of claim 15 further comprising:a circumferential bead on the closure; anda circumferential lip on the sidewall of the container whereby the bead and the lip provide an interference snap fit there between when the closure and container are mated together. 18. The package of claim 17 wherein the bead projects outwardly on the closure and the lip is on an interior surface of the sidewall to provide a seal between the closure and the interior of the container. 19. The package of claim 15 further comprising:an outer rim coupling the skirt to the top wall, the outer rim projecting at an obtuse angle from the top wall; andan annular space between the skirt and an outer perimeter of the top wall;wherein the upper edge of the sidewall is interposed within the annular space when the closure and container are mated together. 20.
