摘要： A method for manufacturing a ball pen tip, in which a spring for biasing a ball is assembled to the ball pen tip, includes punching the ball pen tip by a punch from a rear end of the ball pen tip along a central axis direction of the ball pen tip to form a plastic flow ridge formed by plastic flow upheaving radially inward from an inner peripheral wall surface of the ball pen tip to assemble the spring to the ball pen tip by the plastic flow ridge.

摘要： An apparatus for securing a writing implement to a complementary magnetic surface. The apparatus includes a body formed of a ferromagnetic material, the body extending between a first end and a second end of the housing. A first and second end of the body defines an opening that forms a channel extending between a plurality of lateral interior surfaces from the first end to the second end. In an embodiment, a protrusion is disposed within the housing and extends from one lateral interior surface toward the channel. In an embodiment, a stopper may be disposed proximate to the second end of the body and partially extend from a lateral interior surface toward the opening. In an embodiment, the housing receives the writing implement, and a protrusion contacts the writing implement securing it in place.

摘要： A mechanical pencil has a main body housing a lead-feeding mechanism which includes a chuck and a clamping ring. A tapered member is provided at a front end of the main body, and a slider is mounted to undergo back and forth movement within the tapered member. A lead protection pipe protrudes from a front end of the tapered member when the slider moves forward, and an outer pipe is provided at a front end of the tapered member and surrounds a front end of the lead protection pipe. The slider moves backward as the writing proceeds so the lead protection pipe is not bent by a writing pressure, whereby a lead can be fed by a few knocking operations. The outer pipe is fixed to the tapered member or provided on an outer pipe holder inserted into the tapered member. The outer pipe holder is fixed to the inside of the tapered member or disposed to move back and forth in the tapered member.

摘要： A gel application system includes an applicator body having a first surface, a second surface and at least one opening extending through the applicator body from the first surface to the second surface. At least one gel packet is attached to the first surface of the applicator and defines an interior volume containing gel. The interior volume of the gel packet is in fluid flow communication with the at least one opening. The at least one gel packet is made of a material that has sufficient flexibility to allow a user to squeeze and compress the interior volume and expel gel through the at least one opening, by applying a compression force on the gel packet.

摘要： A device at properly aligns a user's hand when gripping a writing implement, such as pencil. The device includes four separate elements that combine in specific ways to grow and/or build a mature grasp. The device includes a base that is configure round the pencil and provides support for the user's fingers. A handle can releasably attach to the writing implement, providing support for the user's palm. A web support can be releasably attached to the handle, thereby stabilizing the user's thumb while gripping the writing implement. The device can also include an independent web positioner support that can be moved closer or towards the base depending on the separation needed. Advantageously, the grip device provides several stages to develop and build a mature grip pattern.

摘要： The present invention relates to a retractable washable marker device. The device is primarily comprised of a barrel, a thrust device, and a marker member saturated with an ink having a tip. The tip can be extended/retracted into the barrel. When not in use, the tip is retracted within the barrel and enclosed in the barrel by at least one flap that covers a first opening of the barrel. In this manner, air is prevented from entering the barrel and drying out the tip and marker member.
