The unique design incorporates a lever-operated, measured dispensing device for one-handed use. This device is composed of an internal shuttle chamber with openings at two locations. As the entire container is tipped forward, fluid enters and fills the shuttle through the fill opening. Because the chamber is restricted to a certain size, a predefined measured amount of fluid is allowed to enter the chamber. When the user has positioned the device over the desired location, he depresses the lever with his thumb. The lever moves the shuttle, within the container, from a fill position to a dispense position. As the shuttle is moved out of the fill position, the fill opening in the shuttle is blocked from receiving any additional fluid from the main container body. When the shuttle reaches the dispense position, the dispense opening is aligned with the opening in the top portion of the pour spout. Fluid is then allowed to empty out of the shuttle, through the pour spout opening and into the desired target location. No additional fluid from the primary container is allowed to empty out of the shuttle.
To use the device, the user picks up the container in a manner similar to picking up a water pitcher and holds it in a tipped position over the target location. The user then grasps the thumb lever. When the user tips the dispenser forward and depresses the thumb lever, a measured quantity of fluid is dispensed. Regardless of how long the thumb lever is held open while the dispenser is tipped forward, no additional fluid can escape. When the user is finished with the dispensing operation, they place the unit down and release the thumb lever. The cap automatically reseals itself. Any fluid residue is trapped by the pour rim and funneled back into the container - leaving no exposed residue.
Form/Structure
The design is based around a standard size container with a larger, improved handle for easier grasping. The top of the unit incorporates a lever, which extends adjacent to top of the handle. The overall body of the unit is distinguished by a triangular, ellipsoid shape, which is caped by a top component of the same shape. Numerous body designs could be offered with the same internal mechanism. The goal of the overall form is to provide unique function and improved ergonomics with a distinguishing visual form to differentiate from conventional containers. Further body designs are anticipated which could provide both improved stacking and/or container nesting. These additional designs may offer improved shipping and denser shelf storage benefits.
Manner or Process of Making
This invention can be made using similar processes to conventional fluid detergent containers. The design is composed of 6 main components.
Lever
The lever handle is an injection molded plastic part with pivot bosses that snap into the top component.
Top
The top is an injection molded plastic part with recessed cavities. The base of the cap has a screw and/or snap lip which attaches securely to the main body. A cylindrical central underbody acts as a sleeve channel to support the shuttle.
Shuttle
The shuttle is an injection molded plastic part composed of a cylinder and top surface component with an upper and lower opening.
Spring
The spring is a standard steel coil spring. Optional designs may include forming the spring out of plastic as a separate component or as a portion of the top or shuttle component.
Retaining Cap
The retaining cap is an injection molded plastic part that is formed to snap over (or be adhered to) the lower lip of the cylindrical center body of the top.
Main Body
The main body is composed of a blow-molded or injection molded, single piece plastic container. The size of the unit is designed to hold approximately 100 fluid ounces. A side handle and top located mounting rim are formed into the container body. Optional sizes could vary significantly for different applications.
