ABSTRACT:
A single-piece, injection molded rack for holding test tubes or similar articles and a mold for producing the same. In a preferred three-tiered form, the intermediate tier is a lattice defined by the intersection of two superposed sets of parallel bars. These two sets of bars are formed by two pairs of correspondingly channeled slides that cooperatively engage to form a portion of the mold cavity corresponding to the lattice. The channels in each set of slides are aligned with the path of movement of the slides to permit their sliding, uniaxial movement relative to the molded bars. To further enable this sliding movement between mold segments and the molded rack, the connecting supports between the top tier and the intermediate tier are provided on the sides of the rack, while the connecting supports between the intermediate tier and the bottom tier are provided on the front and rear of the rack. With this arrangement, the slides that form the lattice of the intermediate tier are free to slide, as well, along the inner surfaces of the supports, which they also help to form.
