How to prevent olive oil from leaking out of the glass bottle?
Jul 29, 2025
Hey there! I'm a supplier of Olive Oil Glass Bottles, and I know how frustrating it can be when olive oil leaks out of the bottle. It not only makes a mess but also leads to wastage. In this blog, I'll share some practical tips on how to prevent olive oil from leaking out of the glass bottle.
Choose the Right Bottle
First things first, the type of bottle you use matters a lot. We offer a variety of options, like the Dark Green Oil Glass Bottle With Wooden Cork. The dark - green glass helps protect the olive oil from light, which can degrade its quality over time. And the wooden cork provides a natural and tight seal.
Another great option is the Square Olive Oil Glass Bottle. Its unique shape not only looks stylish but can also be easier to handle and store. The design is engineered to minimize the chances of leakage.
And if you're looking for a specific size, our 200ml Olive Oil Glass Bottle is a popular choice. It's perfect for smaller quantities of olive oil, and we ensure that it has a proper sealing mechanism.
Check the Seal
Before filling the bottle with olive oil, always check the seal. Make sure there are no cracks or chips in the bottle's opening or the cap. A damaged seal is a major cause of leakage. If you notice any defects, don't use that bottle. We take great care in the manufacturing process, but sometimes a small flaw can slip through. So, it's always a good idea to do a quick inspection.
If you're using a cork, make sure it fits snugly into the bottle. You can gently press it in and give it a little twist to ensure a tight fit. For screw - on caps, check the threads. They should be clean and undamaged. If there's any debris on the threads, it can prevent a proper seal.
Fill the Bottle Correctly
When filling the bottle with olive oil, don't overfill it. Leave some space at the top, usually about 1 - 2 centimeters. This extra space allows for expansion of the oil due to temperature changes. Olive oil expands when it gets warmer, and if the bottle is filled to the brim, the pressure can cause the oil to leak out.
Pour the oil slowly and steadily. This helps prevent air bubbles from getting trapped in the bottle. Air bubbles can also contribute to pressure build - up and potential leakage.
Store the Bottle Properly
The way you store the olive oil bottle can also affect leakage. Keep the bottle upright. Storing it on its side or upside down increases the risk of oil seeping out through the seal.
Store the bottle in a cool, dark place. High temperatures can make the olive oil more fluid and increase the pressure inside the bottle. A pantry or a cupboard away from direct sunlight is an ideal storage spot.
Use Additional Sealing Methods
If you're still worried about leakage, you can use additional sealing methods. For example, you can use a plastic wrap or a food - grade sealant around the cork or cap. This provides an extra layer of protection.
Another option is to use a rubber gasket. Some of our bottles come with rubber gaskets already installed, but if yours doesn't, you can find suitable gaskets at a hardware or kitchen supply store. Just place the gasket between the cap and the bottle to create a better seal.
Regularly Inspect the Bottles
Even if you've taken all the precautions, it's a good idea to regularly inspect the bottles. Check for any signs of leakage, such as oil stains around the cap or on the bottle itself. If you notice any leakage, take action immediately. You can try tightening the cap or replacing the cork.
Clean the Bottle and Cap
Before refilling the bottle, make sure to clean it thoroughly. Wash the bottle and the cap with warm, soapy water and rinse it well. Any leftover oil or debris can interfere with the seal. Dry the bottle and cap completely before refilling.
In conclusion, preventing olive oil from leaking out of the glass bottle is all about choosing the right bottle, checking the seal, filling it correctly, storing it properly, and taking some extra precautions. By following these tips, you can ensure that your olive oil stays in the bottle and remains fresh.
