Abstract (en)
[origin: US5338123A] A double-ended pen has a pair of elongated liquid-holding reservoirs each having a rear end, a front end having a liquid-applying tip, an intermediate portion between the ends and having at the rear end a predetermined relatively small outside diameter, and a snap-type retaining formation. An intermediate coupling sleeve has a pair of oppositely open seats each receiving a respective one of the rear ends and provided with formations for retaining the respective rear ends securely against axial displacement. The sleeve also has a pair of axially opposite ends having axially oppositely directed end surfaces each having a portion extending at an acute angle to a plane perpendicular to the axis. The sleeve ends are of a diameter greater than the outside diameter of the intermediate portions and projecting radially therepast when the respective rear ends are fitted in the seats. A pair of respective caps each adapted to fit over a respective one of the reservoirs each have a rear end substantially of the same diameter as the respective rear end of the sleeve and having an end surface with a surface portion complementary to the inclined portion of the respective sleeve end surface and engageable flush and complementarily therewith in a mounted position of the cap on the respective reservoir. Each cap further has an internal snap-type retaining formation complementary to and engaged with the snap-type retaining formation of the respective reservoir in the mounted position of the cap.
