The LocknLock 4000ml Rectangular Container is an essential solution for families and meal preppers who need a reliable, high-capacity vessel to preserve the freshness of bulk ingredients or large leftover portions. Featuring a patented four-sided locking mechanism and a durable BPA-free polypropylene construction, it provides a 100% airtight and leak-proof seal that effectively prevents odor transfer and spills; however, users should be mindful that its large footprint requires substantial shelf space in smaller refrigerators or pantries.

Check that the silicone seal is properly seated in the groove and not twisted or pinched.
Ensure the container rim is clean and free of food debris that might prevent a proper seal between the silicone and plastic.
Soak the container in a mixture of baking soda and warm water for several hours to help lift stubborn food pigments.
To ensure the longevity of your container, always verify that the silicone gasket is correctly seated within the lid groove before closing. While the container is dishwasher safe, top-rack placement is recommended to prevent warping from high heat. For manual cleaning, avoid abrasive scrubbers that can scratch the polypropylene surface. If you are freezing liquids, leave about an inch of headspace at the top of the container to allow for expansion during the freezing process. The container is fully compatible with standard household refrigerators, freezers, and microwave ovens.
