Bottle/Container Closure TRIZ Cases

Rotating blades cut the inner rim while folding edges inward, eliminating sharp hazards during flat lid removal.

A corkscrew handle uses dual-layer ABS and TPE plastic injection molding to create a composite structure with enhanced mechanical grip.

An integrated differential gear mechanism applies opposing torque to both the container body and lid, eliminating bulky separate clamping structures.

A multiple flavor beverage mixing nozzle injects syrup at an angle to ensure midair fluid mixing.

Segmented channels equalize pressure between the dispensing chamber and bag, preventing overflow while maintaining sterility.

A flux concentrator focuses the magnetic field on adhesive areas, preventing overheating of overhanging seal parts during automated desealing.

A piercing tip insert resolves opening precision conflicts to enable precise viscous liquid dispensing.

An auger drive mechanism directs feed mix longitudinally while a metal ball agitates material to prevent clumping on uneven terrain.

Segmented barriers with double tongue structures reduce welding complexity while maintaining insulation performance against sloshing.

A carabiner gate section pivots on a trunnion to function as a bottle opener lever.

Thermal cutting opens selected gel card holes, preventing needle damage and reagent contamination during automated analysis.

A biodegradable pull tab uses a frustoconical bolt to secure the opening mechanism.
