Closures TRIZ Cases

Segmented lid components engage via a catch button and latch hole arrangement, balancing adult accessibility with child safety requirements.

A separable web links a closed tamper-evident band to the cap, preventing waste generation by maintaining the closure as a single recyclable unit.

A fitment assembly venting pressurized air via a pressure relief mechanism to prevent vacuum formation during high pressure processing.

Concentric pleats enable stable vertical extension of the spout, reducing spill risk during manual pouring.

An embedded electrode design eliminates lead frames in solid capacitors, reducing equivalent series resistance and improving high-frequency performance.

A sparkling wine sprayer with a quick release lever and trigger valve mechanism.

Segmented vent tubes and a sealing reservoir resolve the contradiction between ease of consumption and reliable vacuum prevention in inverted nursing bottles.

Fixing the venting channel to the second tubular body prevents liquid entry and reduces pulsating flow in limp containers.

Wire grooves in a liquid stopper guide conductive wires to the sidewall, resolving interference that prevents proper seating and reducing device compactness.

A grooved sealing cover and metal bracket sandwich hot melt adhesive to contain the material during application.

A squeeze-actuated vent valve arrangement operates by pushing down inside a container to release trapped air without rotating handles.

Segmented convex portions on a hinge cap outer wall disperse mold release resistance, preventing undercut damage while maintaining closed-state stability.

A container manufacturing machine impresses relief shapes on deformable sheets using rotary support cores and ultrasound welding.

Optimizing outer package resin glass transition temperature suppresses leak current and maintains capacitance during high temperature storage.

A bottle cap uses a frangible joint and tool engagement socket to detach a section via torque.

Bottom venting means in flexible pouches enables air penetration behind viscous food, reducing vacuum pressure and residue during emptying.

Positioning the filling nozzle outside the spout prevents damage to the no-spill system integrity while maintaining continuous production volume.

A drug containment device uses a locking mechanism and physical deterrent to secure access ports.

A spring-actuated pressure relief valve manages gas buildup in beverage vessels using inert food-grade materials.

A microwave container uses a rib-shaped heat seal with varying widths to direct vapor release through a specific discharge part.

A vented beverage can end uses a button to transmit tab force for reliable pressure release.

A unidirectional port enables automated filling of sealed specimen containers with fixative solutions, eliminating formalin fume exposure during transport.

A nozzle plunger diverts liquid flow into the reservoir during refilling.

Multiple memory bands segment the spout to prevent venting ear overlap, increasing flow rate and reducing contact.

A cosmetic container integrates a removable thermal compartment to maintain product temperature.

A rotating hollow body with guide slots adjusts button travel to control discharge volume.

Cross-slit aeration valves open under container underpressure to admit air, enabling continuous fluid withdrawal without needle puncture risks.

A vented fitment assembly uses an expanded polytetrafluoroethylene membrane to allow gas passage while preventing liquid escape from flexible pouches.

A movable pouring spout adjusts flow resistance in stand-up pouches, eliminating separate closures and reducing material usage for viscous products.
