To thereafter open the container, a person forcefully lifts a tab () on the covering to tear the covering along a long tear line () that separates the peripheral cover portion () from a lid () formed by a radially inner covering portion. The base () is fixed to the peripheral covering portion (), and together they form a base device (). After the lid has been torn free of the peripheral covering portion, the lid can be closed and latched to the base device and then can be easily opened again. The container is supplied to the store with an adhesive strip () that the clerk activates by shining ultraviolet light (UV) at the adhesive after he/she places the loaded and initially closed container in a UV chamber (), or mechanical latches with tabs engaging shoulders can be used.
