Abstract
A container for packaging items such as semiconductor wafers has a restraining portion with a changeable dimension at an open end that facilitates using conventional loading techniques while also more securely containing the items to avoid undesirable movement of the items in the container. In one example embodiment, the restraining portion includes a sidewall portion that has a first, nominal inside dimension at one end. A second end of the sidewall portion has a second, greater inside dimension at an open end. Another member of the container cooperates with the sidewall portion to change the inside dimension at the open end from the second, greater dimension to the first, nominal dimension. The nominal dimension is selected to correspond to an exterior dimension of the items to be contained within the package so that the container maintains the items in a secure alignment that eliminates lateral movement of the items once the container is secured.
