A partition and cover structure that can be accommodated in a shoebox and can be made from one or more substantially flat elements foldable on themselves, said structure comprising: • a base divided into a first and a second portion ; • a first partition wall including a mutually opposite first and second edge , said first partition wall being connected, by means of a fold, at at least one stretch of its first edge , to at least one stretch of a first edge of said first portion of said base; • a second partition wall including a mutually opposite first and second edge , said second partition wall being connected, by means of a fold, at at least one stretch of its first edge , to at least one stretch of a first edge of said second portion of said base, said second partition wall being also connected, by means of at least one fold, to said second edge of said first partition wall at its second edge , said partition walls being opposable to each other in such a manner whereby when said partition walls are opposed to each other, said first and second portion of said base substantially are consecutive to each other at the respective first edge thereof; • a first, a second, a third and a fourth side wall , two-by-two mutually opposed with respect to said base , at least one of said side walls being connected, by means of at least one fold, to said first or second portion of said base, each of said side walls being connected, by means of at least one fold, to said first or second portion of said base or to another of said side walls , said structure being characterized in that : • said first edge of said first partition wall is cut from said first edge of said first portion of said base at two mutually opposite end stretches thereof; • said first edge of said second partition wall is cut from said first edge of said second portion of said base at two mutually opposite end stretches thereof. • a base divided into a first and a second portion ; • a first partition wall including a mutually opposite first and second edge , said first partition wall being connected, by means of a fold, at at least one stretch of its first edge , to at least one stretch of a first edge of said first portion of said base; • a second partition wall including a mutually opposite first and second edge , said second partition wall being connected, by means of a fold, at at least one stretch of its first edge , to at least one stretch of a first edge of said second portion of said base, said second partition wall being also connected, by means of at least one fold, to said second edge of said first partition wall at its second edge , said partition walls being opposable to each other in such a manner whereby when said partition walls are opposed to each other, said first and second portion of said base substantially are consecutive to each other at the respective first edge thereof; • a first, a second, a third and a fourth side wall , two-by-two mutually opposed with respect to said base , at least one of said side walls being connected, by means of at least one fold, to said first or second portion of said base, each of said side walls being connected, by means of at least one fold, to said first or second portion of said base or to another of said side walls , • said first edge of said first partition wall is cut from said first edge of said first portion of said base at two mutually opposite end stretches thereof; • said first edge of said second partition wall is cut from said first edge of said second portion of said base at two mutually opposite end stretches thereof. <EOS>
