A friction-fit ring secures a disposable foil pan inside a decorative serving dish, improving presentation, transport, insulation, and cleanup.

Clip-on cup holder apertures secure multiple drinks on existing food trays, improving balance and reducing spills during transport.

A fork-shaped glass carrier holds multiple narrow-base glasses in one slot to cut hand contact, spills, and storage bulk.

A wedge-shaped base and pivoting lid parts turn a food transport box into a stable lap tray that helps prevent sliding and retain heat.

A sliding plunger and apex vent expel trapped air from a sealed food container, slowing oxidation and preserving freshness longer.

A movable piston, wiper seal, and lid vent shrink headspace and expel air, helping home users keep oxidized foods fresher longer.

Dedicated recesses and drainage channels keep barbecue tools separated, accessible, and cleaner by removing excess sauce and liquids.

Corner disposal openings in a communion tray reduce drips over filled cups, lowering contamination risk with only a small capacity tradeoff.

A sealed GRAS RFID inlay enables food-package tracking while preventing metal sparking during microwave cooking and transport.

Side walls, a hand inset, and an integrated grip stabilize bottles and glasses on a serving tray to reduce toppling in crowded spaces.

Sliding shelves and selectable support pins turn limited over-bed table space into customizable storage and upright item support.

An elongate thumb slot, underside finger grip, and glass aperture turn a serving plate into a stable one-handed carrier for food and drink.

Adjustable arms, bumpers, and a hand strap stabilize one or two plates of varying sizes, freeing one hand for buffet serving.

Matching tray and lid grooves enable stackable, nestable food containers that limit lateral slippage, inhibit spillage, and save storage space.

A flexible PCM bladder and thermoconductive cover keep direct contact during freezing to hold sensitive samples near 0-4°C with less fluctuation.

Foldable tray sections and a platform create a transportable stadium-style snack display that stays stable when assembled.

Nested tray compartments and a hinged lid keep food and waste separate while allowing flat storage and secure lap use.

A central stacked support holds multiple removable dishes vertically to save table space, improve stability, and reduce spills during fajita service.
