Lock&Lock Food-Storage Solutions
Save Food, Save Money, Save Space
A useful addition to any busy household, Lock&Lock's Classic plastic food-storage containers come in handy for storing fresh and frozen foods--from healthy snacks like cut-up fruits and vegetables to leftovers or dinners for the week. They also work well for keeping pasta, rice, flour, sugar, crackers, cookies, and other cupboard or pantry items fresh for longer, securely stored, and neatly organized. Even more, the versatile storage containers can be used to transport lunches to and from work or school--or even for storing smaller kitchen, office, or craft items.
Lock&Lock's full line of Classic food-storage containers offers a wide range of shapes and sizes--each with a securely locking lid for airtight storage and peace of mind. Furthermore, the clear body of the containers makes identifying contents easy--no labels required.
Ideal for wet or dry food storage.
Airtight Containers with Four-Sided Locking System
Lock&Lock's Classic food-storage containers feature an innovative four-sided locking system for an airtight seal and watertight storage so food stays fresh longer and there's no messy leaks or spills to worry about. The four sides of the locking system promote an airtight seal due to equal pressure to all four sides, along with the hollow-center silicon sealing ring that makes it possible to lock tightly (the silicone sealing ring can be removed for cleaning if necessary).
Made of high-quality BPA-free plastic, Lock&Lock's Classic food-storage containers not only offer an airtight and watertight seal, but they're also durably built for unbreakable, long-lasting use and hygienic, food-safe storage.
The containers can withstand temperatures ranging from -4 degrees F to 210 degrees F, making them suitable for use in the freezer, microwave* (reheating only), and dishwasher (top-rack). The base and lid should NOT be used in the oven, under browning elements, or on the stove top. Another thoughtful design detail includes the fact that the containers can be nested together, and with the lid in place, they can be stacked one on top of the other--particularly useful where space is limited.
*Unlock all four latches and loosen lid before use in microwave.
Detailed Features
Patented Blocking Hole System
Consistent flow of resin--does not produce a weld line along the hinge. | Inconsistent flow of resin--produces a weld line over time. |
Lock&Lock Classic lids feature four side flaps or "wings" that are hinged and slightly flared at the end for an easy grip when opening. More importantly, they come with holes (rectangular-shaped openings) that line up with matching knobs on the base of the containers, making it easy to latch the lid to the base, locking it into place. This patented blocking hole system maintains the integrity of the lid and helps promote an easy, tightly locked container.
- Lid's 4 wings come with holes that line up with base
- Weld line does not form around the hinge piece
- Hinge is designed to be short in length to prevent stiffness when opening and closing
Blue hollow-center silicon band in the lid helps create an airtight, leak-proof seal.
Special Silicone
In addition to its blocking hole system, the Classic food-storage containers feature a blue hollow-center silicon ring in the lid that helps create an airtight, leak-proof seal. Generic silicon with a solid center doesn't compress as well and doesn't have the same restorative power as hollow-center silicon, which means an inferior seal. Lock&Lock's hollow-center silicon seal delivers superior compression and restoration power that helps ensure an airtight seal.
Permeability
When testing the freshness of foods, one of the most important factors is the permeability of the container. In comparison to other brands, the permeability of Lock&Lock products showed to be drastically better.
Strawberries stored at room temperature for 5 days.
The freshness test is determined throughout the world by how much moisture permeates various containers. Test results show Lock&Lock airtight containers allow in 3,000 - 6,000 times less moisture than other containers, making them far more airtight.
Airtight seal means no messy spills or leaks to worry about.
Excellent Airtight Seal
Lock&Lock airtight containers passed the leakage test. Their four-sided locking system makes an airtight seal possible due to equal pressure on all four sides and the hollow-center silicone sealing ring.
Passed the KEMTI bending test.
Durable Design
Lock&Lock airtight containers have also passed the KEMTI bending test. The container and the wing were fixed to the bending test machine and bent 3,000,000 times 80 degrees left to right. If the container were to be used 10 times a day, it could be used for 821 years (semi-permanently).
Hygienic and food-safe.
Healthy Living
Lock&Lock Classic food-storage containers have passed the strict hygiene and safety tests of the U.S. FDA and German SGS. Made of high-quality BPA-free plastic, the durable and heat-resistance containers are food-safe and health-friendly.
Nest and stack for space-saving storage.
Space-Saving Design
When not in use, the cleverly designed food-storage containers nest together, both lids and bases, for compact storage in a drawer or on a shelf.
The containers also offer a stacking system for maximum space efficiency. The flat lids make it easy to stack one container on top of another--a slight edge helps to keep stacked items in securely place, whether in the freezer, refrigerator, or cupboard.
Whether just one or building a collection of several, Lock&Lock's Classic airtight containers offer a smart solution for food storage.
