(57) A storage bin, for example for flour, wheat and so on, comprises a number of corners
as shown in the figure. Typically, there will be four corners. Adjacent wall members
(50, 52) are provided with a respective partial fillet (60, 63). In the case of a
four-sided storage bin these fillets will preferably have been at an angle of 45°
to the adjacent wall but other angles are possible. The partial fillets (60, 63) are
joined by a backing plate (71) to which the fillets are riveted (90, 92, 90', 92',
90", 92"). A weld (100) is provided between the partial fillets (60, 63). For larger
storage bins, which are assembled on site, the weld (100) will comprise an on-site
weld. Such a weld will generally need to be ground subsequently to meet hygiene requirements.
In smaller versions of the bin, the weld (100) can be a shop-laid weld which requires
no subsequent grinding. The completed bin, therefore, has no crevices or closed voids
in which infestation and breeding of unwanted organisms can occur.
