Claims
- 1. A child resistant closure for a container comprising, an inner cap having internal threads for engagement with threads on the container, an outer cap freely rotatable on said inner cap in a closure removal direction, each of said caps having a top wall and a depending skirt portion, the top wall of said outer cap being spaced above the top wall of said inner cap, an annular wall positioned in said space and being integral with the top wall of said inner cap and extending upwardly therefrom, at least one passageway extending through said annular wall, at least one recess in a portion of the skirt of the outer cap alignable with said passageway, at least one latch tab slidably mounted in said passageway, and means mounted on the top wall of said inner cap and connected to said at least one latch tab for sliding said at least one latch tab into the recess to thereby interconnect the inner and outer caps, whereby the closure can be removed from the container.
- 2. A child resistant closure according to claim 1, wherein the means for sliding the at least one latch tab comprises, a manually rotatable hub member, a recess provided in the top wall of said inner cap, and an opening provided in the top wall of said outer cap, said hub member being rotatably mounted in said recess and extending through the opening in the outer cap.
- 3. A child resistant closure according to claim 2, wherein one end of the at least one latch tab is connected to one end of a link, the opposite end of said link being connected to said hub member.
- 4. A child resistant closure for a container comprising, an inner cap having internal threads for engagement with threads on the container, an outer cap freely rotatable on said inner cap in a closure removal direction, each of said caps having a top wall and a depending skirt portion, the top wall of said outer cap being spaced above the top wall of said inner cap, an annular wall positioned in said space and being integral with the top wall of said inner cap and extending upwardly therefrom, a pair of circumferentially spaced passageways extending through said wall, a pair of circumferentially spaced recesses provided in a portion of the skirt of the outer cap, said recesses being alignable with said passageways, a latch tab slidably mounted in each passageway, and means mounted on the top wall of said inner cap and connected to each latch tab for sliding the latch tabs into the recesses to thereby interconnect the inner and outer caps, whereby the closure can be removed from the container.
- 5. A child resistant closure according to claim 4, wherein the means for sliding the latch tabs comprises, a manually rotatable hub member, a recess provided in the top wall of said inner cap, and an opening provided in the top wall of said outer cap, said hub member being rotatably mounted in said recess and extending through the opening in the outer cap.
- 6. A child resistant closure according to claim 5, wherein a pair of circumferentially spaced arcuate flange members are connected to the side wall of said hub member, a pair of links, each link having one end connected to an end of a respective flange member, the opposite end of each link being connected to one end of a respective latch tab, whereby upon rotation of said hub member the latch tabs extend in opposite directions into the recesses in the outer cap to couple the inner and outer caps.
- 7. A child resistant closure according to claim 6, wherein a second pair of circumferentially spaced arcuate flange members are connected to the side wall of said hub member, a pair of circumferentially spaced, radially inwardly extending abutment members connected to the inner surface of the portion of the skirt of the outer cap, said second pair of arcuate flanges engaging said abutment members when the latch tabs have been moved to the coupled position, the first pair of arcuate flanges engaging said abutment members when the latch members have been moved to the released position.
- 8. A child resistant closure according to claim 7, wherein indicia is placed on the top surfaces of the outer cap top wall and the hub member to indicate when the passageways are aligned with the recesses.
- 9. A child resistant closure according to claim 8, wherein additional indicia is placed on the hub member and top wall of the outer cap to indicate that the latch tabs are inserted into the recesses, thereby interconnecting the inner and outer caps, whereby the closure is removable from the container.
- 10. A child resistant closure according to claim 6, wherein the latch tabs, links and associated flange members are made of plastic having integral hinge portions.
- 11. A child resistant closure according to claim 6, wherein the recesses are provided with inclined walls engaged by the ends of the latch tabs, whereby when the closure is rotated in a direction to tighten the closure onto the container, the ends of the latch tabs slide on the inclined walls and are cammed by the walls back into the passageways, said inner and outer caps provided with means for engagement of the inner and outer caps when the closure is rotated in the closure tightening direction.
