A safety collar, systems, and methods are provided. The safety collar includes an anchor for securing the safety collar to a pressurized container and a retention slot for retaining and anchoring one or more pressurized components to the anchor. The safety collar anchors the one or more pressurized components to the pressurized container when the one or more pressurized components are decoupled from the pressurized container without first depressurizing the pressurized container.

One component or embodiment of a locking medical container is the quality of the material used. The sterile non-chemically reactive polypropylene container is suitable for most medical applications. The lock and all its components are made strong to secure the medications from all but the prescribed user. This is done by using a structural method that joins the parts in such a manner as to produce a solid locking unit. The snap in capability of some of the parts used remove manufacture difficulties that are found in other locking devices. This unit when completed is sealed, sterile and very strong. The user simply rotates the tumbler and removes the cavity obstruction to gain access to the contents of the container.

A child resistant cap includes: (a) a main closure base; (b) an outer ring unit that functions as a safety collar; (c) a dispensing mechanism on the base; (d) an overcap. The base attaches to a top dispensing container and the horizontally rotatable ring unit is attached to the base. Alternatively, the outer ring unit is fixedly attached to the container. The overcap has protrusions and the ring has corresponding cut outs. There is a ring cut out gap lock that prevents at least one protrusion from passing through a cut out gap, unless it is moved to a release position after alignment of the ring unit and overcap.
