A plastic storage container assembly is disclosed comprising a storage container configured to receive a locking lid is disclosed. The storage container is comprised of a base, a generally curvilinear sidewall, a locking ledge and a resting ledge and handles. The sidewall has an inner surface and an outer surface and extends upwardly from the base. The sidewall terminates in a continuous curvilinear upper rim that has a generally parabolic profile and defines a terminal edge of the sidewall. The locking ledge traverses the outer surface of the sidewall and is defined by an outwardly projecting step in the sidewall. The locking ledge is disposed below the terminal edge of the sidewall. The resting ledge is disposed below the terminal edge of the sidewall. The storage container includes upwardly projecting first and second handles defining opposed sides of an upper extent of the sidewall.

A button-type airtight container lid having an upper lid, a lower lid, a dish seal ring, a button, a rotary toothed member, a vertical shaft, and a lever spring mechanism; the rotary toothed member includes a sleeve and N spline teeth provided at the top and bottom with a helicoid, respectively; the rotary toothed member is rotatably mounted at the vertical shaft fixed on the button; the upper lid being provided at the bottom plate with an N-groove spline hole, the bottom plate has an end gear at the bottom, which includes 2N end teeth; the tooth groove of the N-groove spline hole being located at the tooth groove section of the end tooth; the lower lid includes a 2N tooth end ratchet, whose ratchet tooth is adapted to the lower helicoid of the spline tooth, with N greater than or equal to 3.

Aspects of the present invention are directed to a child-resistant container comprising a lid and a vial. The lid has a side wall, an inner surface and a lid cover. The lid cover includes a top, a bottom, and a front surface and at least two lid hooks protruding from the bottom surface. The vial contains an opening accessing a cavity and a rim extending around at least a portion of the opening, the rim having at least two moveable tabs partially affixed to the rim and movable about a pivot point. The movable tabs contain tab hooks above the pivot point for engaging with the lid hooks to secure the lid cover to the vial. The moveable tabs are displaceable outwardly away from the lid to disengage the tab hooks from the lid hooks by pressing inwardly on the moveable tabs below the pivot point.

A locking container lid with actuating handle and an accompanying container to which the locking container lid is able to be selectively secured. The locking container lid with actuating system that includes a spring-loaded handle and an alignment system that ensures the handle can only be actuated when the container lid is upright. It also has a locking mechanism that includes spring-loaded opposing locking wings that move laterally and are sized to engage substantially more than half of the rim of the accompanying container when in a locked position. The locking container lid with actuating handle and accompanying container are structured so that once it is locked on the accompanying container, the locking container lid can freely rotate around the accompanying container but cannot be lifted off absent actuation of the actuating handle while the container lid and accompanying container are standing upright.

A material loading device includes a main body defining a receiving cavity and an opening. The receiving cavity receives materials. The main body defines a buckle groove at the opening. A buckle rod movably coupled to the main body at the opening buckles into the buckle groove. A foolproof mechanism is arranged on the main body. A thimble of the foolproof mechanism is slidably coupled to the main body. One end of the thimble is located in the buckle groove. When the buckle rod is buckled into the buckle groove, the buckle rod drives the thimble to slide relative to the main body. A display member of the foolproof mechanism is coupled to the thimble. The main body defines a plurality of recesses corresponding to the display member. The thimble drives the display member to slide relative to the recesses to switch the display member displayed through the recesses.
