Dispensing Apparatus TRIZ Cases

Movable elevator platform displaces upward via screw assembly to bridge filling voids in consumer care product packages.

A piston electric driving device moves within a columnar storage cavity to pressurize and dispense toothpaste, eliminating manual squeezing waste.

Rotating a screw-coupled piston sweeps viscous residue from container walls to prevent waste and maintain an airtight seal.

A depressed portion on the outer container inner surface guides inner corner deformation, reducing residual contents trapped in undeformed lower portions.

Threaded connector assembly links aerosol can to spray gun, enabling one-handed operation and airtight seal for complete paint residue removal.

Tactile discontinuities on the cover enable reliable locking while reducing structural complexity and protecting contents from humidity.

A fluid dispenser uses a spring-loaded receiving ring to switch between locked and free positions for reservoir attachment.

A rigid carrying case uses a stiff curved handle to prevent entanglement during rapid deployment.

An inner container body with a small-diameter section reduces dead space volume while an air passage introduces outside air to expel remaining content.

A dispensing device with a floating lid prevents suction vortices and air intake, ensuring uniform portioning of viscous foods like ice cream.

A toner cartridge with a movable handle biased toward an open orientation facilitates safe handling and installation.

Rotating indexing rods spread separation force along container flanges, preventing damage and equipment jamming during sequential feeding.

Axial piercing mechanism prevents undesired aeration during transport by holding element in non-piercing position until insertion.

A motorized drawer array shifts horizontally to dispense items from a high-density storage matrix.

A tubular container uses a deployable skirt portion to enable relaxed collapsing of the inner vessel during product dispensing.

Nested separation caps and an integrated pump housing prevent leakage while simplifying the assembly process for heterogeneous contents.

A refillable container uses a lid-mounted restraint part to secure the inner container during removal.

A holster frame uses two independent safety guards to retain a pistol securely while allowing rapid extraction.

Cutting holes and applying pressure detaches inner bags, reducing production time.

A medical instrument tray uses a tensioned flexible grommet sheet to securely hold various tool shafts without permanent fixtures.

Chemical adhesion joins the flexible bottom to the rigid body, eliminating visible injection points while maintaining seal tightness.

A cartridge core with circumferential recesses secures film during injection molding.

Protruding seal rim fills the internal channel between panel and frame, eliminating retention niches for radioactive material without adhesive tape.
