Abstract: A container (10, 55) suitable for the packaging of a block of cheese for maturing, the container comprising an assembly of separately formed wall members (11, 51, 55). The wall members (11, 51, 55) forming the sides of the container each include a planar wall section (12, 52, 56) and means (17, 53, 58) associated with an outer side thereof to define passages (15, 54, 59) adjacent said planar wall section and open to the atmosphere for circulation of air therethrough for cooling purposes. Corner forming means (22, 22', 61) integral with the wall members, and detachably connected to mating corner forming means of the adjacent side wall members to hold the side wall members in an assembled condition. In one example the sidewall members have a single planar wall section (52) on the outer side of which webs (53) are provided to define passages in the form of channels (54).
