The present application provides a porous sintered multicomponent applicator nib and methods of making and using these nibs. The porous nibs are made from sintered plastic particles. These nibs are used with liquid applicators devices, medical devices, writing tools or cosmetic applicators to apply liquids containing high solids or pigments to surfaces such as metal, paper, skin, hair, tissue or a wound.

Provided is a writing implement that maximizes the effective area of a viewer portion allowing visual recognition in the writing direction and that facilitates writing at a high level, at the same time. This writing implement is a writing implement A, including for example, a pen tip 20 that feeds ink from a writing implement body 10 and has a viewer portion 33 allowing visual recognition in the writing direction. The pen tip 20 is comprised of, at least, a writing part 25 and a retainer 30 having the viewer portion 33, an ink feeder portion 26 for feeding the ink from the writing implement body 10 to the writing part 25. The minimum width X of the viewer portion 33 is 3.7 mm or greater and a length Y of the viewer portion 33 is 7.4 mm or greater. The ink feeder portion 26 is arranged on one side of the viewer portion 33. Specifically, the ink feeder portion 26 is preferably adapted to be positioned on a near side during writing (on such a side that the pen tip 20 is located on an obtuse angle side of the ink feeder portion 26).

The present invention uses a material that is not conventionally used in fountain pen nibs in order to provide a fountain pen nib that is completely different from the prior art. This found pen nib comprises one of corundum, topaz, emerald, and garnet as a main material. It is also possible to replace the heart hole and the slit of the nib with a groove that is added to the rear surface of the nib. By using one of the abovementioned gems as the main material in a faun-tain pen nib, it is possible to achieve wear resistance and chemical resistance in the fountain pen nib while imparting a luxurious feel and originality to a fountain pen.

An enclosure apparatus is adopted to a dispensing container having a dispensing side such as but not limited to maker or a candy container. The enclosure apparatus comprises a cap, a lid, and a tubular sleeve having a first end and a second end. The lid is attached to the cap by a hinge and rotatable around the hinge to be in open position or close position. The tubular sleeve is coaxially disposed inside the cap, wherein the cap is relatively slidable along the tubular sleeve. The enclosure apparatus encloses the dispensing side of the dispensing container inside the cap when the cap slides toward the first end of the tubular sleeve and causes the lid in the close position, wherein the dispensing side extends outside the cap when the cap slides toward the second end of the tubular sleeve and causes the lid in the open position.

An electronic smart pen is disclosed that comprises a housing with a twist ring and a marker that is configured to be in an exposed state or in a retracted state. In the exposed state a tip of the marker is exposed from the housing, while the retracted state has the tip being enclosed by the housing. The smart pen also comprises an internal power switch that toggles the electronics of the smart pen between an on-state and an off-state. Rotating the twist ring provides a combined mechanism to move the marker from the retracted state to the exposed state, while also toggling the power switch from the off-state to the on-state so that the marker is automatically extended when the pen is turned on.
