Stackable unit

A stackable unit (100a) comprising:

• (a) two longitudinal sections (104a), each having a ‘C’-shaped cross-section comprising a horizontal upper end (204a) and a horizontal lower end (206a);
• (b) two transverse sections (102a) joined to the longitudinal sections (104a) to produce a frame;
• (c) at least one trough (106a) intended to contain a food product where the longitudinal axis is parallel to the longitudinal sections (104a) and where each end is fixed to the transverse sections (102a);
• (d) under each trough (106a) there is fixed a cover (108a), where the longitudinal axis is parallel to the longitudinal sections (104a) so that when the stackable unit (100a) is stacked on another identical stackable unit (100b), each cover (108a) of the stackable unit (100a) comes to cover a trough (106b) of the lower stackable unit (100b);
• and
• (e) further comprising at least two vertical posts (110a) distributed over and fixed to each longitudinal section (104a), the upper face of each post (110a) serving as a rest for the lower surface of a post of a higher stackable unit, and the lower face of each post (110a) coming to rest on the upper face of a post (110b) of the lower stackable unit (100b) or on a floor;
• (f) further comprising at least two alignment studs (112a) and, for each alignment stud (112a), an alignment aperture, each alignment stud (112a) being insertable into an alignment aperture of a second stackable unit during stacking, and each alignment aperture being provided to receive an alignment stud of a third stackable unit during stacking.
