Drywall mud dispenser closure system

A drywall mud applicator access opening closure system, said system including:

• a drywall mud applicator having an access opening therein, said access opening defining a fill aperture being configured for receiving mud for usage by said drywall mud applicator;
• and
• a closure assembly being removably positioned over said access opening and closing said access opening to inhibit air from entering said access opening, said closure assembly comprising:
• a wall having a front side, a back side and a perimeter edge, said front side being planar;
• and
• an aperture cover being attached to and extending away from said front side, said aperture cover having a size and shape configured to cover said access opening to prevent air from entering the access opening, said aperture cover having a tubular shape having a proximal end attached to said wall and a distal end spaced from said wall, said distal end having a well extending therein configured for receiving a conduit fluidly coupled to the access opening;
• said perimeter edge extending outwardly away from said aperture cover to define a flange between said aperture cover and said perimeter edge to facilitate gripping of said wall, said front side of said flange being continuously planar from said perimeter edge to said aperture cover, said perimeter edge being defined as a juncture of said front side and said back side, said perimeter edge being spaced from said drywall mud applicator when said distal edge of said aperture cover is adjacent to said drywall mud applicator to define a gripping space between said drywall mud applicator and said flange.
