A storage crate has a side access doorway, which is preferably closable by a hinged door. Preferred crates are also collapsible in some manner, most preferably using pivots disposed between the floor and two of the sides, and horizontally along in about the middle of those two sides. Depending on the configuration, collapsing can advantageously reduce the height of the crate by at least 50%, 75% or more. Preferred crates are also stackable, most preferably by virtue of at least two of the sides have sufficient wall strength such that one could safely stack of at least three of the crates when unfolded to an operating configuration, and when each of the crates are loaded with at least 10 kilograms of stored material.
