Resilient spray bottle with tube - has pressure relieving port in top part of wall

摘要

The resilient spray bottle has a spray tube extending as far as its bottom, and is squeezed to discharge the contents. In the top part of the wall is a port, pref. with a marking, and through which any pressure is relieved which may build up internally due to external temp. fluctuations etc. The port is shut off by the finger when using the bottle, and can typically have a covering flap lying loose against its outside end. The design avoids the risk of dangerous or inflammable material being discharged through the nozzle due to the bottle having been left in the sun etc.
