Venting Means TRIZ Cases

A packaging valve uses a liquid seal and spacer to release internal gas through a controlled channel path.

Pre-scored venting structure in the bag construction automatically releases internal pressure during popping, preventing seal failure and content spillage.

Rolled rim geometry prevents liquid blocking at the outlet opening, ensuring reliable discharge from fresh meat packaging containers.

A flexible cooking container uses a press-fit seal with an integrated pressure relief flap to maintain internal conditions during heating.

Stackable food containers use integrated vents to release trapped heat and moisture, preventing condensation that sogs fried goods.

Sliding the outer can expands volume to extract air, maintaining a moisture-free environment without complex assembly.

A boring drill featuring a flat surface and notch forms round holes in container outer shells.

A paper bag uses separate adhesive elements and a tear-off strip to enable size adjustment and multiple reuse cycles.

Laminated film container uses a trench opening system to vent steam pressure, preventing premature package failure during microwave cooking.

A leak-proof straw cup integrates a nested storage cavity to hold the water outlet portion securely within the receiving portion.

Score layer vents steam predictably when internal pressure exceeds limits, preventing heat injuries and preserving food quality in frozen vegetable packaging.

Flexible laminate containers with gas barrier layers enable controlled dispensing of fluent products.

Welded sheets enclosing molded ribs create a unitary deck that resists insects and reduces fire retardant material costs.

A lid assembly with a flexible seal compresses against the container inner surface to create an airtight closure.

Nested reservoirs in a single container allow simultaneous dispensing of two liquids through one opening, preventing internal mixing and preserving quality.

A compact augmented permeation system uses gas-permeable membranes to move hazardous gases from sealed containers without mechanical venting.

Segmented openings in this industrial container reduce manufacturing costs and assembly complexity compared to traditional open head drums.

An inwardly widening recess on the container wall accepts a vent valve, preventing wall collapse from negative pressure while enabling flexible placement.

Perforated exhaust holes discharge vapor to prevent pouch rupture while preserving food moisture and quality.

Segmented wig storage boxes stack vertically to solve transport inefficiency, using removable dividers and screens for secure retention.

Segmented membrane connection reduces material input and manufacturing complexity while maintaining reliable sealing stability under pressure.

A recloseable can opening device uses a sliding base plate actuated by a tab to open and seal the container aperture.
