Caps TRIZ Cases
- Semirigid Pouch Shape Stability and Recycling
Sealing flexible walls to a rigid base preserves the pouch shape for sorting, resolving recycling inefficiencies caused by flat flexible packaging.
- Cup Lid With Laser-Weakened Polymer Film
A cup lid uses a CO2 laser to create lines of weakness in its polymer film for controlled peeling.
- Capping Device Bead Locking for Pressure Resistance
A capping device uses a bead resting against the container neck to lock the cap in an open position.
- Drizzle Safety Seal with Aperture and Pull Tab
Segmented seals resolve tamper resistance versus pouring control by enabling restricted flow via a removable secondary cover.
- Tamper-Evident Closure With Asymmetric Notch Alignment
Asymmetric notch geometry prevents accidental realignment, ensuring the drop band separates from the skirt upon first opening.
- Spindle Nut Axial Drive for Rotary Closure Device Format Change
Coordinated brushless drives adjust the processing element position to eliminate manual cam changes during format transitions.
- Medical Sprayer Cap with Breakable Bridges for Single Assembly
Breakable bridges enable one-step assembly while preventing product stagnation and ensuring tamper evidence.
- Screw Cap Neck Segmentation for Sealing Integrity
Segmented neck geometry and intermediary support rings prevent thermal contraction leaks while maintaining low unscrewing forces.
- Vacuum Closure Panel Deflection for Silent Sealing Verification
A composite closure panel deflects downward under vacuum pressure to verify seal integrity without generating audible snap-through sounds.
- Resealable Metal Beverage Container with Curled Seal Lip
A resealable metal beverage container uses an outward curled seal lip and cooperating lug channels to define a pour opening.
- Bottle Adapter Sloped Surface Residual Fluid
A bottle adapter connector uses a sloped surface to direct fluid into the syringe conduit.
- Smart Container Cap With Display For Skincare Adherence
Integrated smart cap uses ambient data to deliver real-time usage feedback, resolving adherence monitoring gaps in manual regimens.
- Child-Resistant Closure with Flexible Ratchet Fingers
A dual-wall closure uses flexible resilient ratchet fingers to engage blow-molded container threads.
- Medication Container Labeling System for Adherence
Specialized information label on medication containers links to online management systems, resolving patient adherence issues caused by limited health literacy.
- Closure Elastic Seal and Skirt for Sterile Container Sealing
A closure integrates an elastic annular seal member with a generally annular skirt to engage the container neck directly.
- Cap Knurling Design for Low-Profile Closure Grip
Upper and side knurls on the cap tube portion improve rotation ease by increasing friction area without raising overall height.
- Inclined Leading Tube Liquid Cosmetic Container
An inclined leading tube warps back to align the applying portion, eliminating visual obstruction during mirror use.
- Resealable Adhesive Torque Retention for Leak Prevention
A resealable hot melt adhesive provides controlled removal and reseal torque on container closures.
- Steel Sheet for Crown Cap with Uniform Ferrite Grain
A steel sheet for crown caps uses controlled chemical composition and processing to maintain uniform ferrite grain size.
- Composite Closure Snap-Fit and Hot Air Welding
A composite closure uses a two-piece snap-fit rim and directed hot air to melt thermoplastic surfaces for secure sealing without adhesives.
- Bottle Cap and Fitment Assembly Simultaneous Securing
Integrated cap and fitment assembly secures to bottle in one threading operation, reducing packaging time compared to sequential installation.
- Freeze-Drier Container Stopper Reducing Activation Force
A container stopper mechanism uses inclined cylindrical surfaces to lower friction during locking engagement.
