Description

  The present invention relates to a container for containing a liquid, and more particularly to a refillable liquid container.

  Several refillable perfume bottles have been disclosed in the prior art, but perfume bottles with such refill mechanisms are usually sealed to the bottle opening by a thread or other means. If a stop plug is required and the jar needs to be refilled, the sealing plug must be twisted and removed, which is inconvenient, time consuming, and some sealing plugs are contained in the bottle except for threaded connections. However, such a seal requires a relatively large pressing force on the sealing plug to achieve an interference fit, and a small pressing force is required. If there is a gap fit, the liquid may leak from the bottle and volatilize at room temperature.
