ABSTRACT:
A cap device for securing an instrument, such as a ballpoint pen, to a web of flexible material. The device comprises a stem portion and a body portion which collectively define a first, second and third surface, with the first surface being disposed between the second and third surfaces. The surfaces are disposed in a spaced array to form a longitudinally extending gap which is serpentine in cross section and arranged for receipt of the web of material to bend the web about the surfaces to accomplish a substantially non-traumatic gathering of the web by the device. The device is slidable from a first position wherein it covers the tip of the writing instrument to a second position wherein the tip is exposed. Means are provided to ensure that the device does not slide off the instrument.
