Why do flasks leak

Dents, punctures and cracks in your bottle will definitely produce leaks. You can place waterproof tape over the crack as a temporary fix until you get food-grade silicone sealant to repair your bottle. Some screw-top lids have gaskets lining the inside to make them fluid-tight.

A regular problem with rubber gaskets is that they hold moisture and collect mold over time. Not only can this create leaks but also presents a health hazard. Removing the gasket, washing it separately and letting it dry before putting it back inside the lid is a good way to prevent this issue. The natural aging of a rubber gasket makes it break down slowly. This is accelerated when you use your water bottle for hot beverages. The sealing capacity of your lid is diminished when the gasket is worn down and can only be restored by replacing it with a new one.

Gaskets are supposed to fit tightly into the lid to ensure optimal sealing. Over time, it is likely for them to stretch, move around and even fall. If your rubber straw is leaking, you might have debris built up in the vent valve. Turn the cap over and locate any trapped object. In most cases, you will be able to easily remove it with a toothpick, taking care not to damage the material. If this does not work, gently peel back the rubber seal and clean the area.

As a last resource, try dismantling the mechanism making sure that you do not lose any of its parts. Clean any accumulated dirt and cautiously reassemble the elements.

Old bottle mouths might have worn or rusty threads that make it difficult to twist the lid into its position. A misplaced lid will surely lead to leakages.

You might need to clean the threads, replace the lid or even purchase a new bottle. If your bottle is too full, the weight of the water can create enough pressure to overflow. Shake the bottle after closing it to check whether there is any water coming out. There are other problems that affect the functionality of your water bottle.

Here we explain some of them. The surface of the bottle comes in contact with the moisture in the air, which turns from gas into liquid and sits on the walls of the bottle.

As such, this pressure can cause the cap seal to leak or even completely burst. Pipeline Packaging can help you test bottles and cartons — especially under humid conditions.
