Abstract
A writing instrument includes a nose section that is connected to a barrel housing portion that contains an ink reservoir for holding ink for delivery to a writing nib. A cap may be releasably secured to the nose section with a magnetic-mechanical connection assembly to cover the nib to protect the nib from damage and to prevent ink evaporation.
Claims22
An instrument comprising:
- a nose section having a hollow channel and a first opening at one end of the hollow channel;
- a barrel housing portion having an interior, the nose section being at least partially disposed within the interior of the barrel housing portion;
- a cap releasably attached to the nose section to enclose the opening;
- and
- a magnetic-mechanical connection assembly between the cap and the nose section that provides magnetic and mechanical force to secure the cap to the nose portion, the magnetic-mechanical connection assembly including at least one bayonet pin disposed on one of the cap and the nose section and at least one locking channel disposed on the other of the cap and the nose section.

A writing instrument comprising:
- a nose section having an opening at one end;
- a writing nib extending through the opening;
- a barrel housing portion connected to the nose section opposite of the writing nib, the barrel housing portion having an ink reservoir for holding ink to be delivered to the writing nib;
- a cap releasably connected to the nose section, the cap protecting the nib from damage;
- and
- a magnetic-mechanical connection assembly that provides connection force for releasably connecting the cap to the nose section;
- wherein the magnetic-mechanical connection assembly includes at least one nose magnet disposed on the nose section, at least one cap magnet disposed on the cap, at least one locking channel formed in an inner surface of the cap, and at least one bayonet pin formed on an outer surface of the nose section, the bayonet pin being sized and shaped to fit within the locking channel to mechanically secure the cap to the nose section, such that the barrel housing magnet and the nose magnet are aligned to provide an attractive force therebetween.
