Caps TRIZ Cases
- Captive Screw Closure With Pivoting Plate Strain Relief
A pivoting plate separates axial pulling from cap tilting, reducing strain on retaining elements and preventing screw-cap separation.
- Toner Container Shutter and Rotating Cap for Leak-Resistant Replenishment
A movable shutter and rotating cap control toner discharge, enabling replenishment without replacing the entire process cartridge.
- Threaded Bottle Caps With One-Way Teeth and Spring Valves
Asymmetric threads and spring-biased valves help bottle caps resist unauthorized removal while controlling fluid flow in upside-down installations.
- Double-Vessel Container With Deformable Friction-Fit Protrusions
Elastic protrusions adapt to blown-vessel tolerances, securing a removable inner vessel for refilling and waste sorting.
- Closure Assembly with Corrugated Wings for Stiffness and Easier Molding
A corrugated center portion stiffens plastic closure wings, while flat base and top sections support mold alignment and lower leakage risk.
- Container Cap Manufacturing Tool With Retention Incisions
A blade set forms incision lines and connecting pins that keep container caps attached after opening, reducing loss and soiling.
- Water Bottle Side-Filling Cap for Shallow Sinks
An attached side-filling port enables refilling from shallow sinks and fountains, while a built-in filter helps purify incoming water.
- Fluid Transfer Connector with ENFIT Couplings for Accurate Dosing
ENFIT-compatible couplings, resilient flanges, and sealing mechanisms support accurate transfer across bottle sizes while limiting dosing errors.
- Dosing Bottle Closure With External Volume Indicators for Precise Measurement
External volume indicators replace hard-to-read internal scales, helping the reusable dosing bottle deliver accurate, low-waste measurements without liquid contact.
- Silicon-Carbide Composite Container Closure With Thermal Expansion Buffer
A silicon-carbide container pairs a 1–3× lid-to-wall thickness ratio with an intermediate bond layer to resist thermal cracking.
- Tethered Hinged Closure with Frangible Opening Indication
Frangible members signal opening while a tethered retention band keeps the hinged cap coupled and open for easier drinking with less spillage.
- Cap Rotating Equipment With Pneumatic Clamping for Clean Sampling
Pneumatic expansion rings clamp and rotate chemical bottle caps without direct handling, helping reduce contamination during semiconductor sampling.
- Separable Container Cap Structure for Easier Plastic Recycling
A separable body, cover, and use-trace belt simplify plastic cap recycling while retaining convenient opening after use.
- Liquid Container Closure Cap Snap Connection for Hygienic Pre-Assembly
An adhesive-free snap connection secures a dropper insert and sealing washer for hygienic pre-assembly and easy initial detachment.
- Grooved Test Tube Stoppers for Headspace-Free Oxygen Sensing
Longitudinal grooves let oxygen-barrier stoppers displace fluid without trapped headspace, supporting faster optical oxygen measurement in test tubes and plates.
- Cap Rotating Equipment with Pneumatic Clamping for Clean Sampling
An expansion ring clamps and releases sampling-bottle caps for automated rotation, helping reduce manual handling and contamination in semiconductor production.
- Hinged Container Cap With Detachable Separation Part for Recycling
A hinged cap integrates the separation part and fixing feature to simplify plastic recycling while enhancing secure container sealing.
- Discharge Member with Outward Resin Layer for Moisture Protection
Repositioning the functional resin layer toward the tubular member’s outer circumference limits moisture exposure and preserves contents quality.
- Crystallised Polymer Container Closures for Long-Term Openability
Crystallising the contacting polymer surfaces limits chain diffusion, preserving easy opening after long storage while supporting recycling.
