Abstract
A child resistant closure and container according to the present invention include a container having a neck with an engagement mechanism such as an external thread. The container also includes at least one container lug, and preferably a pair of lugs disposed on opposite sides of the container. The child resistant closure includes a top wall with at least one skirt depending from the top wall. Locking teeth are disposed in a set on the inner surface of the skirt, with the locking teeth being arranged circumferentially around a portion of the inner surface, and the locking teeth being arranged axially offset from one another. The closure may also include a thinned-out region in the vicinity of the locking teeth to facilitate deformation of the closure.
Claims17
A child resistant closure, comprising:
- a top wall;
- a skirt depending from the top wall;
- a set of locking teeth disposed on an inner surface of the skirt, the locking teeth being arranged circumferentially around a portion of the inner surface and the locking teeth in the set being axially offset and radially spaced apart from one another;
- wherein the skirt includes a thinned-out region relative to a region adjacent the set of locking teeth, at least one of the locking teeth being disposed on the thinned-out region.
A child resistant closure, comprising:
- a top wall;
- an inner skirt depending from the top wall, the inner skirt including an internal thread;
- an outer skirt depending from the top wall, the outer skirt including an inner surface;
- and
- at least one set of locking teeth disposed on the inner surface of the outer skirt, the locking teeth in each set being arranged circumferentially around a first portion of the inner surface, and the locking teeth in each set axially offset and radially spaced apart from one another;
- wherein the outer skirt includes a thinned-out region relative to a region adjacent the set of locking teeth, at least one of the locking teeth being disposed on the thinned-out region.
A child resistant closure and container, comprising:
- a container including a neck having a container engagement mechanism, the container including at least one container lug;
- and
- a closure, including:
- a top wall;
- an inner skirt depending from the top wall, the inner skirt including a closure engagement mechanism, the closure engagement mechanism cooperating with the container mechanism;
- an outer skirt depending from the top wall, the outer skirt including an inner surface;
- and
- at least one set of locking teeth disposed on the inner surface of the outer skirt, each set of locking teeth being arranged circumferentially around a portion the inner surface, and the locking teeth in each set being axially offset and radially spaced apart from one another, each set of locking teeth corresponding to a respective one of the at least one container lug;
- wherein when the closure in a closed position one of the locking teeth engages the respective container lug.
