A funnel based on bivariate normal distribution is provided, and belongs to the field of daily tools. The funnel is formed by connecting a funnel body in a shape of a bivariate normal distribution with an outlet tube. The funnel body can be formed by rotating a normal distribution curve around the axis of symmetry z with a positive direction pointing to a deep part of the funnel, towards which the fluid flows. An outlet tube is a conical structure with a wide upper part and a narrow lower part. The surface of the funnel body has arbitrary order smoothness at everywhere. The design is simple and the fluid experiences little resistance when it flows through the inner surface. Thus, the funnel can effectively prevented blockage during the transport of fluid, powder and granules and the transport efficiency is remarkably improved.

A container that includes a container body adapted for containing a flowable material for storage and dispensing through a dispensing opening in the container body. A funnel is positioned in a stowage location in the container body and is adapted to be removed from the stowage location and moved to a flowable material-receiving location physically-separate from and proximate to the dispensing opening in the container body. A wiping sheet is positioned with the funnel in the stowage location and adapted to be removed from the stowage location and used to wipe and absorb the flowable material.

A hopper bottom for supporting a cylindrical side wall of a grain bin includes a hopper wall having an inverted cone shape supported on upright support legs. A manifold duct is supported above the hopper wall to define a manifold passage therein extending circumferentially adjacent to the peripheral edge of the hopper wall. A plurality of outlet openings formed in the manifold duct in communication from the manifold passage to an interior of the hopper wall for open communication with the grain bin thereabove. An inlet opening extending through the hopper wall in alignment with the manifold duct receives ventilation air from a blower to direct the flow through the manifold duct and into the grain bin through the outlet openings of the manifold duct.

The present invention is directed to a funnel for use in refilling a vehicle fuel tank from a container. The funnel is adapted to be fixed to the fuel tank inlet so that a person adding fuel to the vehicle fuel tank does not need to hold it in place during the refilling operation. This allows a person to use both their hands to hold the container containing fuel and decant the fuel in a more controlled manner. The funnel also has an inlet opening where the peripheral rim is substantially horizontal when the funnel is fixed in an operational position. With the peripheral rim being substantially horizontal the funnel is able to receive and direct fuel into the fuel tank with minimal spillage.

A gardening apparatus includes a feeder cup, a connector, and a central axis. The feeder cup includes a first pouring section, a second pouring section, a third pouring section, and a fourth pouring section. The feeder cup and the connector are concentrically aligned along the central axis. The feeder cup and the connector are adjacently connected to each other as the feeder cup provide storage area for water or fertilizer. The first pouring section, the second pouring section, the third pouring section, and the fourth pouring section are radially integrated into the feeder cup to channel through the stored water or fertilizer. The connector functions as a fastening body to secure the feeder cup to existing watering wands or a handle so that the hard-to-reach botanical can be reached.
