A disposable moulded fibre slipper pan liner 20 comprises a bowl 22 with a base 24 and a plurality of side walls 26 upstanding from the base. The upper end of the side walls defines a rim 28 extending around the upper edge of the bowl. A shelf section 34 extends from the front edge 36 of the rim of the bowl. The shelf 34 slopes downwardly from its rear end 38 which is arranged at the height of the rim to its front distal end 42 which is arranged at a height substantially level with the base of the bowl. Both the base of the bowl and the distal end of the shelf contact the surface on which the pan is supported, thereby removing any vertical lever arm distance between the tip of the shelf and the base preventing tipping of the bowl when weight is applied to the front end.
