A container (22) includes a container body (26 ) having an open end (34) bounded by a thickened rim (32) having a linear part (36) defining a pintle; a lid body (40) overlying the rim (32) in a closed position and having a channel ( 46) which includes a linear part (42) defining a socket ( 66) and h
A container (22) includes a container body (26 ) having an open end (34) bounded by a thickened rim (32) having a linear part (36) defining a pintle; a lid body (40) overlying the rim (32) in a closed position and having a channel ( 46) which includes a linear part (42) defining a socket ( 66) and having a concave wall (67) extending in close-fitting relation through greater than 180 degrees of the circumferential extent of the pintle around an axis defined thereby to hingably couple the lid body (40) to the container body (26). A container flange (28) extends outwardly around the container body (26) in spaced relation to the rim (32). A skirt (38) is detachable from the lid body (40), and extends therefrom in surrounding relation to the container flange (28) and has a lid flange ( 56) which extends around and grips the underside of the container flange (28) such that, upon detachment of the skirt (38), the lid body (40) is pivotally movable about the axis to an open position apart from the open end (34).

I claim: 1. 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. 2. An apparatus as recited in claim 1 further comprising a container locking flange peripherally extending around the exterior of the container body in spaced relation to the rim and being rigidly connected to the container body; and a peripheral skirt detachably connected to the lid body and extending therefrom in surrounding relation to the container locking flange, the skirt having an inwardly-disposed lid locking flange which extends peripherally around the container body and grips the underside of the container locking flange to prevent removal of the lid body from the container body, whereby, upon detachment of the skirt, the lid body is pivotally movable between the closed position and the open position. 3. Apparatus according to claim 1, wherein the linear part of the rim has formed thereon, at least one outer, upwardly tapering necked-in portion to facilitate insertion of the linear part of the rim within the linear part of the channel during assembly. 4. Apparatus according to claim 1, wherein the concave wall includes a pair of spaced-apart said protruding hooked portions. 5. Apparatus according to claim 1, wherein the channel extends around the entirety of the circumference of the lid body, the lid body including a tubular part which defines in part the outer wall portion of the channel, the rim being positionable within the channel. 6. Apparatus according to claim 5, wherein the lid body is rectangular and includes a lid locking flange projecting inwardly from the tubular part, said lid locking flange gripping the underside of the rim to releasably resist removal of the rim from the channel when said rim is positioned within said channel. 7. Apparatus according to claim 2, wherein the channel extends around the entirety of the circumference of the lid body, the lid body including a tubular part which defines in part the outer portion of the channel and includes a lid locking flange gripping the underside of the rim to releasably resist removal of the rim from the channel when the rim is positioned within the channel, with the skirt being detachably connected to the tubular part. 8. Apparatus according to claim 6, wherein and the socket is aligned along one side of the lid body. 9. Apparatus according to claim 6, wherein the lid locking flange is located on the side of the lid body opposite to that along which the socket is aligned. 10. Apparatus according to claim 5 wherein said tubular part is sized such that, an end portion of the tubular part extending from the linear part of the channel, is urged into press fit engagement with an outer surface of the container body as said lid body is rotated into said open position, thereby providing releasable support for the lid in said open position. 11. Apparatus according to claim 10 wherein the lid open position is 90 degrees about said pintle axis from said closed position. 12. Apparatus according to claim 7 wherein the tubular part of the lid body and the skirt are formed integrally and divided by a peripheral groove. 13. Apparatus according to claim 7, wherein the tubular part of the lid body is formed with thin membrane windows therein on either side of the lid locking flange and bordering on the peripheral groove, so that detachment of the skirt leaves downwardly disposed thin membrane notches on either side of the lid locking flange. 14. Apparatus according to claim 13, wherein the thin membrane windows are formed with strengthening ribs therein. 15. Apparatus according to claim 6, wherein the tubular part of the lid body is formed with downwardly disposed thin membrane notches on either side of the lid locking flange. 16. Apparatus according to claim 15, wherein the thin membrane notches are formed with strengthening ribs therein. 17. Apparatus according to claim 6 wherein the lid body includes an outer surface, said outer surface including a recessed portion at the position of the lid locking flange, thereby indicating its location. 18. Apparatus as recited in claim 1 wherein said resilient plastic material is polyethelene. 19. Apparatus as recited in claim 1 wherein said resilient plastic material is polypropelene. 20. Apparatus as recited in claim 9 wherein the tubular part includes an end portion extending from the linear part of the channel, and is sized such that the end portion engages an outer surface of the container body when said lid is rotated about the pintle axis to a position less than 90 degrees from the closed position, thereby preventing the lid from being opened beyond said position and urging said lid to return to said closed position. 21. Apparatus as recited in claim 6 wherein said lid body is square having four equidistant sides.
