Rigid Containers TRIZ Cases

Slots along the lid hinge and a front latch address unreliable carton opening while preserving secure closure and optional plate separation.

Integrated paper clamping tabs join packaging layers without adhesives or staples, supporting stable, recyclable, and automated appliance-packaging assembly.

Convex aperture segments enlarge finger-tab surface area, making tight packages of containers easier and more comfortable to carry.

Heat-sensitive layers reveal heating attempts at glued portions, while a movable closure supports reclosure and easier manufacture.

Side-wall recesses and protrusions secure roof-window components without adhesives or straps, reducing material use and aiding recycling.

Corrugated paperboard neck retainers hold multiple bottles in a box, supporting drop-test protection, fast assembly, and recyclable shipping packaging.

Corrugated paper, opposed window openings, and transparent film enable direct stacking without extra trays while limiting film sagging and product abrasion.

A hinged shelf folds against the side panel, reducing folding steps while preserving safe access to items below.

A folded corrugated cardboard cooler uses panel segmentation, locking tabs, and covered handholds to balance collapsibility with structural strength.

Universal connectors lock crate attachments into side openings, enabling reconfigurable storage while preserving stackability and access.

Foldable divider panels partition a tray into compartments for organized article display while preserving a simple, material-efficient structure.

Separate corrugated-cardboard compression members reinforce corner zones, enabling lighter boxes with up to 29% less fiber than conventional methods.

A circumferential bevel positions an auxiliary fluid container away from the closure, preserving reclosure and pressure without adhesives.

Arcuate fold lines and segmented retention structures secure cylindrical articles while limiting material use and absorbing impact.

Mixed-material blister packaging makes recycling and opening difficult; a paper card and cover use a bend line for clean separation.

A single corrugated-fiber-board blank forms tall stacking sidewalls and low end walls, reducing material use while keeping products accessible.

Receiving slots support hanging tabs in outer packaging, helping prevent creases and tears during transport or storage.

A collar-mounted cutter breaks the separation membrane while hollow retaining elements prevent ejection and help limit plastic usage.

Locking foldable walls create a stackable display carton that supports branding while reducing material costs and theft concerns.

An edge tape folded into the rim adds sealing material for heat bonding the polymer-coated blank to a plastic lid and preventing leaks.

Perforated fold edges let a cellulose tray tear open cleanly while glued sealing edges protect contents and reduce plastic disposal.

A pallet-mounted anchor deck and releasable sleeve locks prevent spillage while enabling reusable, size-adjustable cargo enclosure.

Detachable skids and resilient dovetail or bayonet-like couplings make this pallet easier to convert, handle, and repair.

An inclined top wall and removable opening device improve outpouring and reduce splashing when drinking directly from the package.

A slanted top wall, separation membrane, and peel or pull-tab opening make pourable products easier to consume on the go.

Nested base and lid geometry aligns side walls during stacking while allowing movement for closing, reducing effort and material use.

Elastic foldable tabs irreversibly lock one closure while a second closure supports reopening with visible tamper evidence.

A multilayer packaging blank uses a separation membrane and weakness lines to support reusable openings, clean cuts, and leak control.

A designated opening, separation membrane, and opening device support direct consumption while package geometry preserves handling stability.

Cardboard layers enclosing spaced mineral-wool carrier elements balance compressive strength and low weight while supporting recyclable pallet construction.

See how compact cardboard, reinforced flaps, and a locking tab improve bag-in-box aesthetics, printability, and structural strength.

Plunger portions fit container recesses while support plates rest on rims and fastening elements prevent tipping or slipping.

Upward bends elevate the pull-tab lift portion for easier finger access while preserving beverage-can stacking compatibility and shadow-bead clearance.

Perforation lines enclosing hot melt adhesive spots maintain secure container bonds while enabling clean pack separation and recycling.

Vertical deck protrusions stabilize drums during transport, while a monolithic thermoset composite body limits particle release.

A single blank forms the food container and condiment pocket, separating contents during transport and serving.

This case uses flat-pack carton and insert components to protect pharmaceutical containers from lateral, top-load, and bottom impacts with recyclable paperboard.

A movable separation panel lets the container shift from flat to box and formed configurations, using less material and simplifying assembly.

Spliced reels in a divided carton keep container carriers organized for uninterrupted dispensing while reducing tangling and equipment complexity.
