Self regulating vent for a paint supply vessel

Abstract

A vessel ( 1 ), in particular for containing paint, comprising a reservoir ( 2 ) and a closure lid ( 3 ) which reservoir ( 2 ) is provided for being closed by said closure lid ( 3 ), which closure lid ( 3 ) is applicable on top of a liquid application tool ( 4 ), said vessel ( 1 ) having an air inlet comprising a plurality of openings ( 9 ), said closure lid ( 3 ) comprises a conically shaped part, characterised in that said air inlet being provided with a closure valve made of flexible elastomer material, said valve being resiliently mounted on said air inlet in such a manner as to cover said plurality of openings, of which each opening having a surface area of at the most 15 mm 2 , and as to open upon a predetermined pressure difference between a first pressure inside said vessel and a second pressure outside said vessel, said closure lid ( 3 ) being provided with a protrusion applied on said conically shaped part and forming a flat contact face for said valve.

1 . A vessel ( 1 ), in particular for containing paint, comprising a reservoir ( 2 ) and a closure lid ( 3 ) which reservoir ( 2 ) is provided for being closed by said closure lid ( 3 ), which closure lid ( 3 ) is applicable on top of a liquid application tool ( 4 ), said vessel ( 1 ) having an air inlet comprising a plurality of openings ( 9 ), said closure lid ( 3 ) comprises a conically shaped part, characterised in that said air inlet being provided with a closure valve made of flexible elastomer material, said valve being resiliently mounted on said air inlet in such a manner as to cover said plurality of openings, of which each opening having a surface area of at the most 15 mm 2 , and as to open upon a predetermined pressure difference between a first pressure inside said vessel and a second pressure outside said vessel, said closure lid ( 3 ) being provided with a protrusion applied on said conically shaped part and forming a flat contact face for said valve.
