Bags TRIZ Cases

Diagonal side welds meeting at the symmetry plane minimize head space and enable self-supporting stacking while ensuring controlled product release.

Segmented enclosures prevent cross-contamination between food products and sterile medical devices.

An outwardly positioned overlapping strip covers a filter to vent gases while blocking moisture and powder loss.

Segmented gel compartments in a sleeve cold pack conform to leg curves, resolving poor contact and high application costs.

A valve bag uses two plastic layers with offset perforations to vent air during filling while maintaining a moisture barrier.

A resealable tobacco pouch closure assembly uses a segmented two-part mechanism with a living hinge to secure the package.

A flexible container uses a breachable bubble to open a fluid channel and activate a self-sealing valve for controlled dispensing.

Crosslinked (meth)acrylic copolymers maintain bond strength in alkaline environments, preventing delamination of packaging structures.

Gripping ridges and surface texture on the closure profile improve graspability and sealing ease when wet or slippery.

A plastic spout with gradient wall thickness compensates for deformation to ensure even pressure distribution during film bag sealing.

Flexible thermal runaway shields line sealable bags to dissipate heat and prevent propagation during shipping.

Deployable sleeve covers lifting lug openings to prevent contamination during transformer transport.

Welded seams and PVC-coated Kevlar anchors provide weather protection without rusting or damaging truck beds.

Fold-over paperboard seals use perforated tear lines to reveal tampering, avoiding complex manufacturing costs.

Polyolefin-silicone copolymers in liner sidewalls resist flex-cracking from liquid sloshing, eliminating dunnage costs and labor while maintaining reliability.

A caster wheel assembly integrates ultraviolet LEDs into the swivel frame to sterilize pathogens on the wheel surface.

Reducing the midbody circumference via side pinches eliminates internal baffles, stabilizing filled bags and lowering shipping costs.

Internal guides form a tortuous fluid path in the dose pack, preventing accidental leaks and spills without requiring a separate cap.
