Liquid Dispensing TRIZ Cases

A two-stage actuator shifts from a blocked first position to a locked operating position, improving tamper evidence and easy food dispensing.

Headspace CO2 pressure ratios meter dispensed carbonated water without wetted flow meters, preserving carbonation and measurement accuracy.

A maintaining mechanism locks the discharge valve until concentrate discharge is complete, preventing leakage during cap removal.

A tapered guide surface inside the pouring nozzle smooths carbonated beverage flow to suppress foaming and maintain high GV during pouring.

Phase-separating membranes and pressure control cut foaming during carbonated beverage dispensing while preserving syrup consistency and hygiene.

A reversible pump and two-way valve recirculate pulp-containing ingredients to prevent settling and keep beverage flavor consistent.

An added riser tube opening improves aerosol homogeneity at low fill levels, preserving spray pattern and enabling more complete can emptying.

Microwave-safe polymeric aerosol packaging heats food or other products quickly before dispensing while managing pressure and recyclability.

Aerosol spray quality drops as contents settle, so this riser pipe adds a side cut opening near the bottom to keep patterns stable and empty more fully.

A fixed retainer keeps the bar gun O-ring aligned as the valve stem slides, reducing leakage and improving seal life under pressure.

Parallel mixing channels and an impeller dissolve CO2 through repeated impacts, avoiding high-pressure tanks while improving gas-liquid uniformity.

A line of weakness in the actuator fixing crown enables reliable can attachment during use and easy separation for recycling.

Instant gas-liquid mixing uses the water hammer effect to carbonate water without pressure tanks, reducing explosion risk and operating complexity.

An annular-gap diffusion tube creates laminar flow in a beverage nozzle to limit gas breakout, foam, and splashing while preserving carbonation.

Openings in the chamber insert expand metering volume to 100 µl without changing the valve body, preserving seal contact and manufacturability.

RFID-verified connector locking blocks incompatible beverage packages from supply lines, reducing contamination, waste, and manual handling.

Integrated axial valves let cleaning fluid sanitize the coupler and beverage lines in place while isolating the keg interior from contamination.

A dual-tube nozzle extension lets operators mark animals from a safer distance, reducing aerosol exposure and animal stress.

Needle-sealed transfer heads use pressurized gas to purge containers and move wine without removing the closure or exposing it to air.

Grooved preform surfaces create fluid channels that prevent bag-drum adhesion during blow molding and support complete beverage delivery.

Angled flow directors and a check valve limit residual base fluid mixing with diluent, reducing foaming and inadvertent dispensing.
