ELCOS Granted Korean Patent for Pump Cap for Double Container

ELCOS has been granted a Korean patent for its Pump Cap for Double Container (Patent No. 10-2650924), registered with the Korean Intellectual Property Office on March 20, 2024.

The invention makes refilling more convenient by improving how the inner container of a double container is replaced. The pump cap can be combined with a general inner container, so the inner container can be swapped at refill while the outer container stays in use.

In conventional structures, the inner container is twisted off and replaced, and a separate sealing film or inner cap has to be peeled off and discarded. Here, the pump cap presses onto the inner container instead of screwing on, so a fresh inner container can be swapped in easily. Because the cap can also be fitted to existing commercial inner containers, it offers good compatibility.
