As a further advantage, the new and improved container 10 facilitates stacking since the rim 17 and cylindrical wall portion 14 bear the weight of a second container. Thus, it is possible to use aluminum lids 20 rather than extra strength materials and it is possible to use existing warehousing and shipping materials.
Conventional cans 60 have a deep groove 53 which collects dust and dirt in the shipping and handling process. A typical prior art lid 50 is shown in FIG. 5. The lid 50 has no raised center portion 31 and the surface 51 is below the rim 52 having a groove 53 adjacent the rim 52. This groove 53 is a problem with the accumulation of dirt and debris.
