Caps TRIZ Cases

Flexible annular lips on the plunger maintain a fluid seal against the chamber wall, preventing leaks in viscous flowable compositions.

A frangible lidding film forms a puncturable tab member to enable finger-operated package opening without tools.

Flexible cap walls move between retained and unretained positions, resolving the trade-off between child deterrence and adult ease of use.

A container fitting uses a partitioned aperture to secure mounting on varying bottle mouths.

A flat tire repair liquid container uses a non-elastomer closing stopper and elastomer sealing member to prevent leakage during storage.

A synthetic resin bottle bottom displaces inward under vacuum pressure to maintain structural integrity.

Servomotor rotates cap before contact to suppress thread overriding and prevent filling liquid spill.

A pour spout fitment uses a co-axial tamper-evident band and flange system with detents to secure the cap.

Segmented sealing stoppers prevent drinking tube rotation while visible tamper-evident parts break off during unscrewing.

An integrated stopper design reduces assembly complexity and cleaning stagnation by merging the protective cap and base collar into one unified structure.

Segmented lid design allows independent rotation to lift the culture dish, resolving contamination risks from two-handed handling.

A beverage container uses a movable cartridge to isolate components until dispensing, enabling controlled flow through a cap mechanism.

Outward projections on the transition section absorb impact energy, preventing contamination while maintaining seal integrity.

Dynamic cap detection records random positions to orient closure elements correctly relative to container embossings, eliminating faulty visual appearance.

Unimodal polyethylene with specific molecular weight distribution prevents closure cracking and maintains seal integrity under hot liquid sterilization.

Non-metallic receptacles shield RFID tags from metallic interference, enabling reliable contactless identification on gas bottles.

Segmented elastomeric septum prevents contamination by using distinct width portions to maintain a fluid-tight seal after needle puncture.

An elastic sealing gasket isolates the storing chamber from the feeding path, resolving airtightness issues while maintaining low manufacturing costs.

Segmented lower ring engaging elements allow radial movement, reducing tensile forces when rotating the cap from tilted open to closed position.

Concentric threads fit multiple spout diameters while a hinged, extendable swab resolves applicator loss and depth limitations.

A waterproof lighter case with a gas lock strap prevents accidental button presses while the semi-flexible sleeve creates a watertight seal against moisture.

A smart container integrates a scale and sensor array within its cap to weigh contents directly.
