Detailed information

This vented screw cap is a special lid designed for Bürkle space-saving canisters, featuring an integrated venting function. It has a standard thread (S 50 × 4, DIN 50) suitable for the wide opening of flat canisters and ensures that air can flow back into the canister during pouring or filling. This prevents glugging or unwanted pressure build-up in the canister, allowing the liquid to flow evenly and without interruption. The screw cap is equipped with a manually operated vent valve for air pressure equalization. Since venting does not occur automatically, the valve must be opened manually during emptying to allow air to enter and ensure a smooth, consistent flow of the liquid.

Typical application area of the product

Helpful wherever space-saving canisters (flat canisters) are used and liquids need to be dispensed quickly and without splashing. Especially in storage and filling rooms of laboratories, workshops, or production areas, this special cap ensures smooth, splash-free pouring. When filling cleaning agents, solvents, or even food ingredients (e.g., cooking oil, syrup) from narrow canisters, the vented cap allows controlled flow and minimises the risk of spills or uncontrolled air intake. At the same time, the canister remains sealed and transportable when closed, ensuring professional handling at every stage.
