A preload mechanism for an actuator is disclosed that includes a rotating element configured to rotate about a pivot. The rotating element has a first contact point that is configured to couple to the actuator such that contraction of the actuator displaces the first contact point such that the rotating element rotates from a first position to a second position. The preload mechanism also includes a bias element with a first end that is coupled to a second contact point of the rotating element and a second end configured to be pinned relative to the pivot. The bias element has a line of action extending from the second end through the first end. The line of action has an offset distance that is the minimum distance between the line of action and the pivot. The offset distance has a first value when the rotating element is in the first position and a second value when the rotating element is the second position, the second value being smaller than the first value.

A container for dispensing product includes a housing having an interior space. A rigid flip top assembly is disposed on the housing, and includes a lever, a lid, and a flange. The lid covers a dispensing orifice when in a closed position. The lever has a first end and a second end, and the lid is connected to the flange at a hinge proximate the second end. The lever longitudinally extends over a fulcrum. When a force is applied to the lever proximate the first end, the lever pivots at the fulcrum about a pivot axis, and the second end of the lever moves the lid from the closed position toward an open position.

A breathing assistance apparatus has a lid and latch assembly configured for one-handed operation. The apparatus also includes a hinge assembly that separates when over-rotated but that reengages upon closing of the lid onto the main body of the apparatus.

An example storage chest is provided. The example storage chest may include a box portion and a lid. The box portion may include a front wall, a rear wall, and a floor attached to the front and rear walls to form a primary compartment for storage of items. The lid may include a front panel, a rear panel, and a top panel attached to the front a rear panels. The rear panel may be pivotably coupled to the rear wall of the box portion. The front panel, the rear panel, and the top panel may define a secondary compartment within the lid for storage of items. The secondary compartment may include a lid storage compartment comprising a hingedly affixed door.

A beverage container closure or lid that is adapted for closing an open end of a beverage container. The lid is selectively couplable to the beverage container and includes a selectively openable stopper that when closed, creates a fluid-tight seal between the beverage container and the environment. The stopper may be selectively opened by a user by the user pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the user releases the button. Thus, a user may open and close the beverage container closure using a single hand without the need to remove the beverage container closure from the beverage container.

The lid covers a dispensing orifice when in a closed position. The lever has a first end and a second end, and the lid is connected to the flange at a hinge proximate the second end. The lever longitudinally extends over a fulcrum. When a force is applied to the lever proximate the first end, the lever pivots at the fulcrum about a pivot axis, and the second end of the lever moves the lid from the closed position toward an open position.
