An indicating funnel for filling a container through an opening is formed as two peripherally joined, coaxially arranged funnels, one nested within the other to define a cavity between adjacent funnel walls. A vertically movable fluid level indicator is reciprocatable between the funnels and behind a transparent wall portion of the exterior funnel for viewing between a first lowered position and a second raised postion. The indicator in its lower portion is operably associated with a float positoned within the lowermost portion of the cavity between funnels to indicate fluid level in a serviced container. The exterior funnel, at its intersection with an associated spout, optionally incorporates positoning flanges for maintaining funnel alignment and stability cooperatively with various sized openings. Additionally, the fluid level indicator may include a luminescent feature enabling enhanced visibility and a cap skirt portion lessening spill potential.

A funnel for indicating fluid level in the upper portion of a container being filled thereby, comprising: an outer funnel portion, including a first wall portion for acceptance of a fluid joined to a first spout portion, defining a first surface, and an inner funnel portion, including a second wall

A funnel for indicating fluid level in the upper portion of a container being filled thereby, comprising: an outer funnel portion, including a first wall portion for acceptance of a fluid joined to a first spout portion, defining a first surface, and an inner funnel portion, including a second wall portion joined to a second spout portion for directing discharge of fluid, defining a second surface, and positioned within the outer funnel portion to define a space between said first and second surfaces, float means including a float axially displaceable in said space between said first and second surfaces, for movement relative to said spout portions responsively to contact with an underlying fluid level, and indicator means, positioned within said space between said first and second surfaces, structurally communicating with said float means for indication of displacement of the float axially of said inner and outer funnel portions.
