Closures TRIZ Cases
- Dispensing Container Valve Body Segmentation for Airtightness
A dispensing container valve body separates the sealing interface from the pressure-transmitting main body portion to reduce squeezing force.
- Fuel Hose Adhesion via Magnesium Oxide and DBU Salt
A laminated fuel hose combines a diene rubber layer with specific accelerators and a quaternary THV resin to enhance interlaminar adhesion.
- LED Bulb Packaging Using Flexible Bags and Connector Sleeves
Conformable polymer containers allow nested LED bulb packing to increase container density, while protective sleeves shield Edison connectors from damage.
- Reversible Plunger Cover with Closure Mechanism
A reversible plunger cover secures the tool via a closure mechanism to contain fluids during removal.
- Cap Annular Protruding Portion Suppresses Liquid Dripping
An annular protruding portion on the inner plug intercepts residual liquid content before it reaches the lid member.
- Synthetic Resin Bottle With Ridge And Valley Folds For Stable Inverted Refilling
A blow-molded synthetic resin bottle uses thin peripheral walls with ridge and valley folds to enable volume-reducing deformation during depressurization.
- Rocket Hatch Radial Seal and Quick-Release Closure
A rocket hatch integrates a radial seal with a quick-release latch mechanism for rapid pressure-tight closure.
- Flexible Hollow Profile Plug with Recess for Assembly
A hollow profile insertion plug uses a flexible plastic base body and cover side to enable easy assembly into open profile ends.
- Foam Discharge Device Air Cylinder Extension
Extending the air cylinder into the pressing head secures sufficient volume for small container mouths, maintaining consistent foam quality.
- Child-Resistant Locking Cap for Laminated Rollerball Tubes
Rotating locking teeth engage container slots to prevent child access while allowing adult dispensing.
- Child Resistant Container With Segmented Locking Ring
Segmented locking rings and extraction principles simplify closure mechanisms while enabling recyclable paper construction.
- Fuel Cap Tether Gap Vapor Venting Design
A fuel cap assembly uses a tether fastener gap to vent vapors, preventing narrow apertures from clogging with dirt or deposits.
- Modular Medical Container Adaptor with Protective Envelope
A modular medical adaptor assembly uses a protective envelope to secure connecting and gripping components for sterile handling.
- Dual Overlapping Flap Closure for Simultaneous Pouring and Shaking
Segmented flaps enable simultaneous pouring and shaking functions while maintaining a secure seal and reducing manufacturing complexity.
- Dispensing Bottle-Top With Part-Spherical Sliding Surfaces
Complementary part-spherical surfaces guide a sliding top piece, eliminating unwanted rotation and complex lateral skirts while maintaining effective sealing.
- Chip-Type Filter Integrating Inductor to Reduce ESL
A chip-type filter integrates an inductor section within a laminated body to reduce equivalent series inductance and resistance.
- Dispensing Closure with Piston Valve and Measuring Reservoir
A dispensing closure uses a piston valve within a measuring reservoir to deliver precise product doses from squeeze containers.
- Composite Pressure Test Door for Aircraft Fuel Tanks
Replacing heavy metal doors with fiber-based composites reduces weight from fifteen pounds to two and a half pounds while maintaining structural strength.
- Reagent Container Shield Plate for Spatter Control
Shield plates intercept spattering reagent through air vents, preventing centrifugal force from staining identification labels.
- Cylindrical Spout with Recessed Air Vent for Oral Motor Development
A cylindrical spout design promotes natural lip and tongue movement while a recessed air vent prevents negative pressure buildup in the bottle.
- Double Slider Valve Fitment for Complete Bag Drainage
Nested internal and external sliders drain flexible bags completely, eliminating fluid waste without increasing manufacturing complexity.
- Portable Fuel Container with Belt-Loop Attachment and Self-Closing Cap
Segmenting storage into a small portable unit reduces refueling trips while maintaining regulatory compliance through an automatic self-closing cap.
