This invention relates generally to dispensing particulates and, more particularly to methods and apparatus for dispensing particulates.
A variety of particulate dispensing devices or spreaders are well known in the industry. At least some of such spreaders include an open-ended hopper that is coupled between a pair of wheels used to propel the hopper. The hopper slopes downward towards a broadcast or discharge port in the bottom of the spreader. However, such spreaders are limited to only dispensing particulates through the broadcast port because of the open-ended hopper. To facilitate preventing foreign objects from inadvertently entering such hoppers, at least some of such hoppers include a solid screw top or a hinged lid that is secured to a top edge of the hopper.
Other known spreaders are hand-held spreaders that include a hopper that feeds a rotating impeller assembly through a slotted opening that is coupled to an actuating assembly. However, within such spreaders, the actuating assembly limits the user to only using the spreader to discharge the product contained therein through broadcast dispensing, increases manufacturing cost, and may increase the likelihood of potential malfunctions.
To overcome these and other problems related to use of known spreaders, the present invention provides methods and apparatus for dispensing particulate from a single container that enables particulate to be dispensed through a shaker top and/or through a broadcast dispenser. In addition, the present invention provides a single container that is optionally reusable. The above advantages and novel features, as well as other features and advantages, of the present invention will become apparent from the description provided in the present Specification and from the accompanying drawings.
