Lock & Lock is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lock & Lock rather than just read about it. In short: Lock & Lock (Korean: 락앤락) is a household products company headquartered in Seoul, South Korea. Since its establishment in 1978, Lock & Lock has been exporting products to 119 countries worldwide.

Key takeaways

Lock & Lock belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lock & Lock to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lock & Lock from memory before moving on to harder problems.

Reference excerpt

Lock & Lock (Korean: 락앤락) is a household products company headquartered in Seoul, South Korea. Since its establishment in 1978, Lock & Lock has been exporting products to 119 countries worldwide. The company has a wide range of product categories for food containers, cookware, tumblers and water bottles. In addition, the company has 11 overseas sales units including in Germany, United States, China, Vietnam, and 87 overseas directly operated stores in the world.

Products and Innovation Lock & Lock's initial success came from the development of the four-side locking system for airtight containers, which was designed to be leak-proof. Over time, its product range expanded to include heat-resistant glass containers, stainless steel cookware, eco-friendly tumblers made from Tritan plastic, and diverse kitchen and home storage goods. The company reportedly launches hundreds of new products annually.

Campaigns

Love For Planet Campaign By recycling the collected airtight containers, 'upcycling eco-bag' was introduced to practice continuous resource circulation. Terracycle and Lock&Lock also collected and recycled tumblers to produce Jeju Olle-gil benches.Terracycle and Lock&Lock collaborate together to bring plastic airtight containers that are left unattended or old in the house to the store, and they will be given a coupon to purchase certain products at a discount.

Worked examples

Example 1 — a first encounter with Lock & Lock

Start with the simplest possible case. Write down what Lock & Lock claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lock & Lock before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lock & Lock ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lock & Lock

In research: Lock & Lock appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lock & Lock in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lock & Lock is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chemical companies of South Korea, Companies based in Seoul, Companies listed on the Korea Exchange, so understanding it makes those chapters shorter.
In everyday life: Look for Lock & Lock outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Lock & Lock in simple terms?

Why does Lock & Lock matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
