Patent ID: 7063230

Claim:
Apparatus comprising: a hollow container body having a thickened peripherally extending rim and an open end bounded by the rim, the rim defining a periphery of the container body and having a linear part which defines a pintle, the pintle defining a pintle axis; and a lid body overlying the rim in a closed position and having a channel formed therein which includes a continuous linear part defining a socket, the continuous linear part of the channel having a continuous concave wall that extends in close-fitting relation over the pintle to hingably couple the lid body to the container body for movement about the pintle axis from the closed position to an open position where the lid body is disposed at an angle to the open end of the container wherein said lid body and container comprise resilient plastic, and said concave wall includes an outer wall portion, said outer wall portion including at least one laterally protruding hooked portion which engages the underside of the linear part of the rim during pivoting from said open position to said closed position, said outer portion of the concave wall being laterally flexible and the hooked portion being dimensioned so as to accommodate disengagement of the lid body from the rim by laterally outwardly flexing of the outer wall portion until the laterally protruding hooked portion is disengaged from the underside of the rim and so as to accommodate installation of said rim into the channel of the lid by pressing the lid onto said rim until the hook portion engages the underside of the rim.
