Patent ID: 7422022

Claim:
A washing appliance comprising: a) an open top wash chamber adapted to accommodate items to be washed and within which wash liquid is circulated, said wash chamber having a top peripheral rim, and wherein said chamber is slidably mounted in said appliance in such a manner that it may be withdrawn horizontally for access thereto, b) a wash chamber lid including a perimeter seal to seal on said top peripheral rim, and said lid suspended in said appliance so as to be moveable from an outer position to an inner position, c) a cam surface sloping downward from an outer location to an inner location, separated by a horizontal distance equivalent to the horizontal spacing of said inner and said outer position of said lid, d) a cam follower on said lid and adapted to interact with said cam surface, e) an abutment on said wash system, f) a complimentary abutment on said lid, wherein said abutments meeting when said wash chamber is substantially retracted, and with continue displacement of said wash chamber to a fully retracted location, forcing said lid from said outer position to said inner position, said cam follower cooperating with said cam surface to direct the path of said lid in moving from said outer position to said inner position, to an inward and downward movement, followed by an inward movement, said downward movement of said lid bringing said seal into contact with said peripheral rim, and said inward movement preventing substantial slip between said lid and said wash chamber.
