Screw-Tight Seal Mouth Design

Built for commuter hot meal markets in North America, the EU and the Middle East, this set is designed specifically for carrying liquid and semi-liquid foods such as soups, porridges and baby food. Each jar lid uses a screw-tight structure paired with a food-grade sealing gasket. When fully tightened, it creates a full enclosed seal that prevents leakage even when inverted or shaken vigorously during transit, so jars can be placed directly inside bags with no spill risk.

Five-Piece Capacity Assortment

The set includes five food jars of different capacities. Users select sizes based on appetite and food type, and can use separate jars for soups, porridges, baby food and side dishes to cover multiple meals for one person or split servings for several people. It addresses the liquid food transport needs that standard flat bento boxes cannot handle well.

Hygienic Easy-Clean Interior

Each jar interior carries an easy-clean antibacterial coating. Soup congee residue and grease rinse away clean with plain water, with no stuck-on film left on the walls. Separate jars prevent cross-flavor transfer between different foods, and the coating suppresses bacteria growth to avoid persistent odors over extended use.

Bulk Sourcing Terms

Dongke Electric Heating supports custom jar body colors, printed brand markings, bespoke set packaging, and adjustable capacity combinations and jar counts per set. Production uses standardized QC procedures, with 100% in-line checks for sealing performance, insulation capacity and material safety, plus AQL sampling on finished batches. Export cartons include internal cushioning to reduce shipping damage.
