Closure Caps TRIZ Cases

Fluorine-contained resin coating on a plastic pouring port prevents highly wetting liquids from dripping at the outlet.

Segmented container profiles interlock with lid slots to withstand internal pressure while simplifying assembly.

A rotating bottle cap housing aligns compartment openings with base apertures to release selected additives.

Segmented hinge tongues interconnect lid and skirt portions to enable rotation beyond 180 degrees.

Variable wall thickness in elongate hinge elements accommodates production deviations while maintaining reliable locking at wide angles.

Optical detection positions pre-printed drawings on crown caps, enabling precise embossing of raised pictograms without deforming the cap structure.

Radial expansion of the first bowl wall accommodates a nested rigid second bowl, securing fluid-tight storage without separate lids.

Pre-weakened sections in the sleeve enable consumers to detach portions for opening while retaining product information, resolving recyclability challenges.

Variable groove depth guides sequential breaking of segmented locking portions, resolving the trade-off between secure locking and easy removal.

Segmenting the inner ring with a recessed portion resolves the sealing versus venting contradiction, preventing cap popping during secondary fermentation.

An annular volume slows viscous liquid flow through friction, preventing leakage and simplifying manufacturing by removing movable sealing lips.

A tamper-resistant lid assembly uses a snap-fit connection between a cup and ring to dispense premeasured liquid amounts securely.

A closure with a removable second part and storage chamber uses a closing member to seal the dispensing opening.

A packaging box cover uses flexible snaps and blocking portions to create a secure closure mechanism.

A three-part bottle closing system uses an elastic part compressed against walls to create a vacuum seal for tool-free opening.

A sensor cap transmits ultrasonic signals through opaque container walls to determine remaining liquid volume.

Compatibility agents prevent cracking in polyethylene bottles containing cellulose fibers, ensuring phase stability.

Adjustable weight mechanism repositions center of gravity along longitudinal axis to reduce user effort during lifting and pouring.

A fitment system with an angled spout and timer mechanism measures precise liquid volumes to resolve variable flow rates in dispensing applications.

A removable strip between the lid lug and screw thread reduces frictional force, lowering opening torque for elderly users.

A cantilevered product holder secures solid cosmetics within a recessed base structure.

A spout-equipped container uses a heat sealed sheet and aluminum regions to form a hermetic seal for hydrogen water.

A threadably mounted dispensing cap separates liquid and dry ingredients until use.

A container closure device uses a radially offset interlock to secure the lid element and chamber.

An articulated pressure relief valve seals container openings, preventing moisture ingress while allowing repeated opening cycles without damage.

A discharge container cap uses a flow groove to return remaining contents into the inner container.

A press-forming method shapes cup workpieces using coordinated inner and outer dies to increase vertical wall thickness.

A capsule design uses a hermetically sealed multi-layered sheet to protect active substances from humidity during storage.

Sliding tubular caps use product pressure to open automatically, preventing leakage through elastic sealing lips that close the outlet during storage.

Mechanical wedging lugs clamp the capsule between the ring and wire-cap, ensuring irreversible single-use security without complex manufacturing.

A single integrated moulding device forms the cap and neck of a package closure simultaneously.

A trigger dispenser connection system uses asymmetric guide ramps to align the dispensing head with the bottle neck for secure snap-engagement.

A flexible packaging cap uses an elastic ridge to seal spouts while scraping inner walls.

A motorized dispensing device uses a lead screw mechanism to deliver fluid medication through a wearable headset.

A dispensing closure uses latch hook members and a stepped shoulder to secure a measuring cup within an outer skirt.

A packaging system closure device joins a container seal and coupling mechanism to enable fluid transfer between separate product components.

A flip-top closure integrates a hook and crossbar to secure the tamper-evident member.

A rotatable cap closure compresses headspace air to maintain internal pressure in plastic containers.

Lateral wall closure removes the neck constraint, allowing large applicators without increasing bottle volume.

Movable cap portions trigger automatic reagent release into the tube, resolving safety risks from toxic preservatives.

A child resistant cap uses a lever and flexible band to unlock the overcap.

A shrink film retaining strap secures a closure cap to a container neck, eliminating guarantee rings and lowering production costs.

Uniform diameter cylinders eliminate tapering and indexing tolerance issues, simplifying ring alignment for easier unlocking.

A liquid chemical applicator uses a rotatable outer cap to control discharge flow through an inner bush portion.

Segmented threads allow the lid to move longitudinally relative to the inner housing, compensating for dimensional deviations in glass containers.

A container closure uses a radially extending rib to transfer doming force and pull the bore seal inward for pressure relief.

Segmented neck rings reduce removal force by creating gaps, solving the trade-off between secure engagement and refill ease.

A lid with a flipable flexible skirt adapts to various container openings.

Vertical guide ribs uniformly expand the anchor ring to prevent tilting and jamming during screw cap assembly on composite packaging.
