- Golf Ball Flask with Golf Tee Funnel for Spill-Proof Liquid Transport
See how a golf ball-shaped flask uses spherical geometry and a golf tee funnel with rubber ring
- Low-Profile Fluid Transfer Structure for Spill-Reducing Drainage
Sloped flow channels, catchment areas, and a drain hole enable compact gravity-fed fluid transfer with less spillage and better containment.
- Support-Collar Funnel Structure for Stable Container Filling
A molded support collar creates a receiving channel that keeps a narrow-neck funnel aligned and stable on containers during transfer.
- Vented Funnel Handle Structure to Prevent Liquid Backup
An integrated vent passageway in the handle lets air escape during filling, preventing backup and spills with narrow-neck containers.
- Particulate Funnel With Trapping Unit for Flexible Cone Filling
The trapping unit catches excess particulate matter around the funnel outlet, preventing contamination while filling flexible cones.
- Split-Able Funnel Structure for Thorough Cleaning Access
A longitudinal split separates the conical funnel into two halves, exposing interior surfaces for thorough cleaning and reduced cross-contamination.
- Living-Hinge Foldable Funnel for Confined-Space Fluid Transfer
A flexible bowl adapts to confined fluid-transfer spaces, then folds over its opening to limit dirt and grime buildup.
- Movable-Wall Filling Device for Flexible Filling and Compact Transport
Movable walls form a funnel during filling and fold for transport, balancing filling volume with compact dimensions.
- Funnel With Recessed Collection Area For Residual Fluid Capture
A funnel design featuring a recessed base with a flat surface and an inlet flange to stabilize vertical positioning.
- Funnel With Integrated Rotating Tool Holder
An integrated funnel design rotates tools within the body to open sealed drains, capturing fluid leaks and preventing spills onto hands.
- Fluid Management Device for IBC Top Surface Utilization
A fluid management device extends across an intermediate bulk container top with a concave surface directing fluids to a drain opening.
- Vented Funnel Design for Viscous Fluid Transfer
A vented funnel with integrated ribs and openings guides viscous liquids into containers while allowing trapped air to escape through dedicated channels.
- Hydrophobic Funnel Liner for Contamination-Free Fluid Transfer
Disposable hydrophobic liners prevent oil contamination in funnels, eliminating cleaning steps and reducing servicing costs.
- Funnel Stem Fins for Stable Receptacle Sealing
Segmented radial fins in the funnel stem resiliently deform to match varying inlet geometries, preventing spillage caused by loose fits on sloped surfaces.
- Bivariate Normal Distribution Funnel for Blockage Prevention
Rotating a normal distribution curve creates a smooth funnel body that prevents blockages and improves transport efficiency.
- Funnel Spacer Retention via Enlarged Post Caps
Enlarged post caps prevent spacer loss in bottle funnels, ensuring complete liquid drainage from inverted containers.
- Torch Refilling Funnel With Valve And Lid Rest
A funnel with a spring valve and lid rest directs liquid fuel into torch canisters, preventing overfilling and wick soiling.
- Meat Grinder Funnel Attachment with Helical Suspension
Helical suspension guides ground meat into containers, reducing spills and improving handling efficiency without adding rigid complexity.
- Multipurpose Vented Funnel with Integrated Venting and Stabilizing Tabs
An integrated vent passage prevents liquid backup by moving air, while stabilizer tabs secure containers.
- Universal Canning Funnel with Skirt and Cutaway for Jar Stability
A tapered canning funnel uses a lower skirt to rest on jar rims, directing food into the container while providing stable support.
- Removable Lining Funnel for Dough Lines
Segmenting the funnel into a permanent body and disposable HMPE lining eliminates on-site cleaning labor while preventing PTFE coating contamination.
- Injection-Molded Funnel with Annular Skirt for Capless Fitment
A unitary injection-molded funnel uses an annular skirt to engage and open a capless fuel tank fitment.
- Collapsible Funnel With Spring-Loaded Arms
Spring-loaded extendable arms collapse the funnel for storage, resolving bulkiness while integrated jaws hold a scoop for precise substance transfer.
- Funnel Assembly With Curved Rim And Support Legs
Curved rims and plate anchors stabilize the funnel on hive feeders, eliminating spillage caused by manual holding.
- Modular Oil Funnel Kit for Spill-Free Crankcase Refilling
Segmented funnel components with interchangeable adapters seal unique filling ports, preventing oil spills during engine maintenance.
