Sloped flow channels, catchment areas, and a drain hole enable compact gravity-fed fluid transfer with less spillage and better containment.

A molded support collar creates a receiving channel that keeps a narrow-neck funnel aligned and stable on containers during transfer.

An integrated vent passageway in the handle lets air escape during filling, preventing backup and spills with narrow-neck containers.

The trapping unit catches excess particulate matter around the funnel outlet, preventing contamination while filling flexible cones.

A longitudinal split separates the conical funnel into two halves, exposing interior surfaces for thorough cleaning and reduced cross-contamination.

A flexible bowl adapts to confined fluid-transfer spaces, then folds over its opening to limit dirt and grime buildup.

Movable walls form a funnel during filling and fold for transport, balancing filling volume with compact dimensions.

A funnel design featuring a recessed base with a flat surface and an inlet flange to stabilize vertical positioning.

An integrated funnel design rotates tools within the body to open sealed drains, capturing fluid leaks and preventing spills onto hands.

A fluid management device extends across an intermediate bulk container top with a concave surface directing fluids to a drain opening.

A vented funnel with integrated ribs and openings guides viscous liquids into containers while allowing trapped air to escape through dedicated channels.

Disposable hydrophobic liners prevent oil contamination in funnels, eliminating cleaning steps and reducing servicing costs.

Segmented radial fins in the funnel stem resiliently deform to match varying inlet geometries, preventing spillage caused by loose fits on sloped surfaces.

Rotating a normal distribution curve creates a smooth funnel body that prevents blockages and improves transport efficiency.

Enlarged post caps prevent spacer loss in bottle funnels, ensuring complete liquid drainage from inverted containers.

A funnel with a spring valve and lid rest directs liquid fuel into torch canisters, preventing overfilling and wick soiling.

Helical suspension guides ground meat into containers, reducing spills and improving handling efficiency without adding rigid complexity.

An integrated vent passage prevents liquid backup by moving air, while stabilizer tabs secure containers.

A tapered canning funnel uses a lower skirt to rest on jar rims, directing food into the container while providing stable support.

Segmenting the funnel into a permanent body and disposable HMPE lining eliminates on-site cleaning labor while preventing PTFE coating contamination.

A unitary injection-molded funnel uses an annular skirt to engage and open a capless fuel tank fitment.

Spring-loaded extendable arms collapse the funnel for storage, resolving bulkiness while integrated jaws hold a scoop for precise substance transfer.

Curved rims and plate anchors stabilize the funnel on hive feeders, eliminating spillage caused by manual holding.

Segmented funnel components with interchangeable adapters seal unique filling ports, preventing oil spills during engine maintenance.

An injection molded transparent funnel uses an integrated exhaust conduit to remove trapped air, preventing splash and enabling clear flow observation.

A funnel design with a flat collection area and inlet flange stabilizes vertical placement to capture residual fluid by gravity.

A funnel assembly with a detachable fill tube and storage guides secures the conduit to prevent kinking during transport.

Grooves on the tapered stem vent displaced air to prevent bubbles while sloped walls guide fluid flow during tilted filling operations.

Segmented nested funnels create an air passage that vents trapped air, preventing pressure buildup and bubble formation during liquid transfer.

A lidded funnel uses a segmented stem to block air passage and a pivot lid to seal the interior space for storage.

A collapsible conical funnel features a magnetic rim that secures the device to ferrous surfaces.

A self-attaching funnel secures to vehicle fuel tanks via friction or threads, eliminating manual holding requirements and reducing spillage during refilling.

A fluid capturing assembly uses a hinged funnel attached to a sign to direct leaking liquid into a removable bag.

A two-vent funnel uses an adjustable outlet extension to guide liquid flow along container walls.

A bifurcating RV funnel uses an adapter portion to engage a support member for stable, hands-free operation.

An integrally formed first passage and detachable second passage enable smooth air discharge, reducing bubble formation and splashing during liquid transfer.

Segmented funnels attach to standard beverage containers, providing large openings for clean saliva expulsion while maintaining portability.

A bucket funnel system uses a conical nozzle to direct fluid discharge from containers.

An aluminum alloy sheet with shape memory retains a custom geometry while rubber layers cover sharp edges to prevent user injury.

A container integrates a stowable funnel and absorbent wiping sheet to enable controlled pouring of flowable materials.

Nested deformable funnels accommodate varying bottle sizes and short necks, eliminating liquid waste from nearly empty containers.

A filling device with a partition wall separates liquid and air passages, preventing overflow during rapid pouring.
