  • Patent number: 5129546
    Abstract: Storage container for button-shaped batteries with a minimum of one channel, which is dimensioned to fit the cross section of the battery and which has an entrance and an exit opening, a slide, which is located inside the channel and which is secured against being pushed out of the channel by means of limit stops at the entrance and exit openings, and locks which permit the passage of the button-shaped batteries only in the direction of the exit opening. The storage container serves to store new and used button-shaped batteries, with the latter being able to be inserted only into the entrance opening, while, at the same time a new button-shaped battery is dispensed at the exit opening. After all new batteries have been used up and the storage container is filled with used button-shaped batteries, the passage is blocked so that no further button-shaped batteries can be inserted.
