Patent ID: 7695208

Claim:
An applicator device ( 1 ) for applying a liquid medium comprising a reservoir ( 2 ) for the medium; an applicator ( 3 ); a protective sleeve ( 5 ) to prevent a damage or an unwanted deformation of the applicator ( 3 ) caused by rapidly flowing medium or a mixing member which surrounds the applicator ( 3 ) in the reservoir ( 2 ) and is rigidly connected with the reservoir ( 2 ), wherein the inner diameter (I S ) of the protective sleeve ( 5 ) is constant in the vicinity of an applicator tip ( 4 ) of the applicator ( 3 ) and exceeds the outer diameter (A a ) of the applicator ( 3 ) penetrating into the reservoir ( 2 ), wherein the protective sleeve ( 5 ) extends down to a bottom ( 14 ) of the reservoir ( 2 ) and bears against the bottom ( 14 ) via a resilient sleeve portion ( 15 ), and wherein in a position of the protecting sleeve ( 5 ) in which the resilient sleeve portion ( 15 ) is decompressed, an axial extension (F S ) of the resilient sleeve portion ( 15 ) amounts to approximately half of the entire axial length (L S ) of the protective sleeve ( 5 ).
