Title:
AERATED PEN CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2012/025243
Kind Code:
A3
Abstract:
Pen cartridge (10) with a front part (11 ), which exhibits a writing member (15) and is provided on a main body (12) and is formed to be arranged in a passage (23) of a pen housing (20). The pen cartridge (10) is provided with an aeration passage (13), which runs at least along a partial area of the front part (11 ), especially according to the length of passage (23). With the pen cartridge an aeration passage may be provided for a pen with substantially airtight housing, via which, at least when the pen is in a state where it is ready for writing, an air exchange and/or equalisation of pressure between the periphery and the interior of the housing is ensured. Irrespective of the configuration of the pen housing of a writing implement or pen, the proposed solution ensures an aeration/ventilation of the interior of the pen cartridge and thereby also of the region of a pressure equalisation aperture of the pen cartridge.
