Abstract
A high quality child resistant container comprising a durable metallic reservoir and durable plastic metal cap. The child resistant container comprises a durable and rugged reservoir and similarly durable locking cap. The cap is secured to the reservoir by a threaded, or bayonet-style connection. Once installed on the reservoir, the cap is prevented from being easily removed by a child, due to child resistant features integrated in the design of the cap and reservoir. Also, a method of reducing friction between the sealing surfaces of a sealed container. Specifically between the reservoir, cap and seal of a container, which allows easier closing of containers which require a simultaneous compression and twist motion to close.
Claims13
A container assembly, comprising:
- a container that is composed of a rigid and durable material, the container having a round opening formed therein, the container having engagement surfaces provided thereon adjacent to the opening, the container having a container axis passing orthogonally through the opening;
- a container lid that has engagement surfaces provided thereon for selective engagement with the engagement surfaces of the container, wherein the container lid is configured for rotational movement around the container axis to selectively engage or disengage the container lid to or from the container;
- and
- a seal positioned between the container lid and the container that hermetically seals the interior of the container from the ambient atmosphere when the container lid is engaged with the container;
- wherein the torque required to rotate the container lid relative to the container to disengage the container lid is less than or equal to 5 ounce-inches;
- wherein the seal is retained by the container lid and the container lid includes first and second surfaces that engage one another and that have a coefficient of friction at or below 0.2 which enables relative rotational movement between the first and second surfaces so that the container lid can be rotated relative to the container without rotation of the seal relative to the container;
- wherein the container lid includes a thrust bearing and a bushing that have surfaces that together have a coefficient of friction at or below 0.2, wherein the thrust bearing comprises the first surface and the bushing comprises the second surface.
