Abstract: A knockdown container or display in the shape of a 3-dimensional container is provide which comprises of two main element types, namely Sheet elements and Edge elements. In this design, all of the main elements of the container are joined one to another by sliding with respect to each other in a sequence that make an open or closed display or container that can easily assembled or disassembled. In particular, the edges of the Sheet elements have a shape that is fitted into matching slots of the Edge elements. The position and orientation of elements are such that they securely restrict unwanted movement of the elements with respect to one another, while minimizing the number of needed fasteners or number of additional restricting components needed to secure the Edge elements.

Abstract: A valve pin actuating mechanism for an injection molding apparatus is provided. The injection molding apparatus includes at least one melt channel and a valve pin that is movable in the melt channel. The valve pin actuating mechanism includes an actuator, a linkage element and a stop. The linkage element has a mechanically upstream connector and a mechanically downstream connector. The linkage element is connected at least indirectly to the actuator at the mechanically upstream connector and is connected at least indirectly to the valve pin at the mechanically downstream connector. The linkage element is rotatable by actuation of the actuator. The stop is configured to engage a limit surface to limit the angle of rotation of the linkage element. The stop and the limit surface are configured to engage mechanically upstream from the downstream connector of the linkage element.
