Abstract: The method stores and/or transports at least partially deformable items, such as caps for containers. One embodiment of the method has the following steps: identifying for at least one item an edge-on plane that is associated with a more deformable direction of the at least one item and an axial plane that is associate with a less deformable direction of the at least one item; and orienting the at least one item such that the edge-on plane of the at least one item is substantially vertical, the at least one item being stored and/or transported in an unsecured manner relative to other deformable items. This method therefore provides cost savings to both manufacturers and users by reducing the number of damaged and deformed items or caps during storage and/or transport.

Abstract: A cap and container assembly can be opened and closed repeatedly and continue to achieve a good seal between the cap and the container. The good seal results from the engagement, of the container neck with cap protrusions, which temporarily deforms the shape of the container and/or the cap as the cap is secured to the container.

Abstract: A cap and container assembly can be opened and closed repeatedly and continue to achieve a good seal between the cap and the container. The good seal results from the engagement, of the container neck with cap protrusions, which temporarily deforms the shape of the container and/or the cap as the cap is secured to the container, and from stopping surfaces which limit the extent of that deformation.

Abstract: A locking closure for use with an associated container includes a closure cap having a top wall portion and a depending skirt portion depending from the top wall portion.
