Description

BATTERY DISPENSER
The present invention relates to a battery dispenser for dispensing batteries to a hearing aid.
BACKGROUND OF THE INVENTION Handling and replacement of batteries for a hearing aid and other small sized electrical devices can be a difficult task for the end user, mainly due to the small size of the devices and batteries. The battery lifetime for such devices is relatively short and thus frequent replacement of batteries is required.
Currently, batteries for small electrical devices are packed in packages with e.g. six batteries. Handling of small batteries may be difficult especially to disabled persons and people with bad sight or shaky hands. Typically, a battery for hearing aids has a first surface, an opposite second surface and a cylindrical wall connecting the first and second surface. Furthermore, batteries for hearing aid devices typically are provided with air tabs on the first surface, and the air tabs must be removed to activate the battery. Removal of air tabs from the batteries may also be a difficult task.
Patent application US 2003/0102326 describes one type of a dispenser for miniature batteries including zink air cells used in hearing aids where the batteries are positioned side by side and the first surfaces sharing the same plane. The dispenser comprises a base and a cover each rotatable with respect to a common axis, a retractable push element and a landing. Air cells are advanced through an opening in the sidewall by pushing the batteries sideways onto the landing. Operation of the dispenser requires multiple operations including rotation of the base and cover and sliding of the push element. Further, one-hand operation of the dispenser is very difficult and in practice almost impossible. SUMMARY OF THE INVENTION
