Abstract
A large light-weight bottle made of plastic of the type used on water dispensers instead of the heavy glass bottle. Each bottle is made of rectangular or square transverse cross-section with spaced reinforcing ribs or bands extending therearound. On opposed flat faces or sides, each bottle is provided, respectively, with a square locking projection and a complemental receiving socket so that a plurality of the bottles can be stacked on their sides with the locking projections and sockets of adjacent sides interfitting to keep the bottles in alignment in the stack and with the reinforcing ribs superimposed for strength.
Claims6
A bottle having a hollow body including at least two opposed straight sides, one of the sides having at least one mortise in its surface and the other a complemental tenon on its surface so that when a plurality of the bottles are stacked on their sides the mortise and tenon at adjacent sides interfit, said body also having reinforcing embossed ribs on the surfaces of said sides which alternate axially with grooves formed therein, the mortises and tenons of adjacent sides of the bottles when stacked on their sides interlocking and serving to also locate the reinforcing ribs axially in alignment so that they are in superimposed contacting relationship to prevent undue distortion of the hollow stacked bodies.
