Child-resistant container and closure

A method for restricting access to a container by a child, the method comprising the steps of:

• providing a childproof combination of container and closure, the container comprising:
• a base and a wall defining an inner volume of the container, the container has an open-top, a neck extends from a periphery of the wall, an outer surface of the neck has at least three lug threads that run consecutively along a circumference of the neck, at least one lower pointer on the wall of the container just below the periphery of the wall, wherein the at least one lower pointer points upwards, and a closure comprising:
• a central section and a skirt that perpendicularly extends downwards from a periphery of the central section, the skirt has an inner surface and an outer surface, the inner surface of the skirt has at least three male threads, at least one upper pointer on the outer surface of the skirt, wherein the at least one upper pointer points downwards,
• wherein the at least one upper pointer and the at least one lower pointer are positioned such that the at least three male threads engage and disengage with the at least three lug threads only when the at least one upper pointer is aligned to the at least one lower pointer,
• wherein each male thread of the at least three male threads is directly above or below the respective proximal end portion of the lug thread when the at least one upper pointer is aligned with the at least one lower pointer;
• positioning the closure above the container such that the at least one upper pointer is aligned to the at least one lower pointer;
• depressing the closure over the neck of the container with a slight force;
• and
• upon depressing, twisting the closure.

A childproof combination of container and closure comprising:

• a container comprising:
• a base and a wall defining an inner volume of the container,
• the container has an open-top,
• a neck extends from a periphery of the wall, an outer surface of the neck has a plurality of lug threads that run consecutively along a circumference of the neck, and
• at least one lower pointer on the wall of the container just below the periphery of the wall, wherein the at least one lower pointer points upwards;
• and
• a closure comprising:
• a central section and a skirt that extends downwards from a periphery of the central section,
• the skirt has an inner surface and an outer surface, the inner surface of the skirt has a plurality of male threads,
• at least one upper pointer on the outer surface of the skirt, wherein the at least one upper pointer points downwards,
• wherein the at least one upper pointer and the at least one lower pointer are positioned such that the plurality of male threads engages and disengages with the plurality of lug threads only when the at least one upper pointer is aligned to the at least one lower pointer,
• wherein each lug thread of the plurality of lug threads has a proximal end and a distal end, wherein each lug thread slightly deflects downwards from the proximal end towards near the distal end, and wherein the distal end sharply tapers downwards contacting the periphery of the wall, a proximal end portion of each lug thread is notched,
• wherein each male thread of the plurality of male threads is directly above or below the respective proximal end portion of the lug thread when the at least one upper pointer is aligned with the at least one lower pointer,
• wherein each male thread of the plurality of male threads is directly above the respective proximal end portion of the lug thread when engaging the plurality of male threads with the plurality of lug threads, and wherein each male thread of the plurality of male threads is directly below the respective proximal end portion of the lug thread when disengaging the plurality of male threads from the plurality of lug threads.
