Child Proof Means TRIZ Cases

A pre-formed notch tab and tear path lower adult opening force in blister packs while preserving child resistance and simple manufacturing.

Inner flaps, reinforcing elements, and locking tabs keep a folding box closed securely while resisting irreversible deformation from frequent use.

Folded inner and outer locking tabs and flaps restrict carton movement and create an audible click to confirm child-resistant closure.

A coded pressure-field lock keeps the inner box secure yet releasable, preventing unintentional opening while staying usable in tight spaces.

Interlocking tray flaps and sleeve openings restrict child access while keeping packaged articles easy for intended users to reach.

Notched overlap zones define breaking portions in the closure, helping block child access while keeping adult opening practical.

Internal tabs on the inner box engage outer-housing recesses to protect the closure from transport and manufacturing damage.

Segmented locking tabs in a paper or cardboard sleeve-and-insert box balance child-resistant closure with adult opening and resealing.

Separate container and case coupling portions simplify production while preserving child safety and repeatable adult opening.

Segmented coupling portions enable repeated adult opening and closing while retaining integrity on standard packaging lines.

A cardboard package unit features a slidably movable closure panel that secures contents without complex mechanical locks.

Waisted contours and an angled slideable actuator resolve ergonomic complexity, enabling precise single-handed cosmetic application.

Segmented casings with nested flaps provide child resistance without complex construction, enabling multiple re-closures.

Segmented locking mechanism prevents immediate opening while auto-stop function restricts tray draw-out distance for secure child-resistant access.

Nesting pouches in an inner bag and outer box prevents sticking and structural failure of water-soluble detergent units.

Segmented inner and outer packages with spring-loaded tabs prevent child access while enabling cost-effective production on conventional machinery.

Spring-loaded extensions in housing recesses block child access while allowing seniors to push the slide open.

A container closure releases via pressure on the outer wall to open the aperture.

A sliding selector aligns openings in outer and inner panels to create a single passage through the package wall.

Interlocking coupling portions on the closure and storage engage to prevent forced opening by children while allowing easy manual operation by adults.

Overlapping flaps with weakening lines delay child access by releasing fragments, preventing bulky closures while ensuring safety.

A locking folding carton uses a movable insert and angled lid opening to secure the package.

Dual-locking tabs on the lid engage wall slots during folding to prevent child access while maintaining adult operability.

A sprayhead uses a rotatable collar to switch between locked and unlocked states.

Segmented coupling system maintains child-proof integrity while signaling tampering via irreversible septum movement.

Segmented flap parts move independently to engage a locking part, resolving the contradiction between child resistance and construction simplicity.

A container with a flexible bottom ring aligns inward protrusions to enable secure access.
