Embodiment Construction

[0010] Such as figure 1 , 2 As shown, the recyclable neutral refill of the present invention includes a tubular refill 1, a nib 6, ink 3 and a suction pipe 7, a nib 6 is installed at one end of the pen refill 1, a ball is installed at the end of the nib, and the other end is an opening. The rod 4 is inserted into the tube of the pen core 1 from the opening, and the top of the push rod 4 is a disc-shaped structure, and there is a rubber pad 5 on the disc, and the diameter of the rubber pad is 0.5 mm larger than the inner diameter of the pen core; the diameter of the disc at the top of the push rod 4 is smaller than that of the pen. The inner diameter of the core is 0.5 millimeters; in addition, there is also a straw with an inner diameter equal to the outer diameter of the pen core and a length of 4-6 centimeters; there is a ring-shaped protrusion 2 at the end near the pen tip 2-3 centimeters away from the pen tip. The front end of the refill has an external thread, the straw ...

Abstract

The invention relates to a gel pen capable of being recycled. The gel pen comprises a tubular pen core, a pen head and pen oil. The pen head is inserted at one end of the pen core. The other end of the pen core is open. The top portion of a push rod is in a disc shape, and a rubber mat is sleeved on the top portion of the disc. The diameter of the top disc of the push rod is smaller than the inner diameter of the pen core. In addition, a sucking pipe is arranged, the length of the sucking pipe is 4-6 cm, and the inner diameter of the sucking pipe is equal to the outer diameter of the pen core. A circle of annular protrusion is arranged at the portion at one end of the pen head, and the distance between the portion and the pen head is 2-3 cm. After the pen oil in the pen core is used up, a user can take off the pen head and mount the sucking pipe, then the push rod is pulled upwards, and due to movement of the push rod, the inner pressure of a pen core pipe is reduced. Due to effect of outside barometric pressure, the pen oil enters the pen core pipe through the sucking pipe. When the pen oil is full by sucking, the sucking pipe is taken off, the pen head is mounted again for being used continuously, and recycling of the gel pen core is achieved. The gel pen capable of being recycled has the advantages of being reasonable in structure, convenient to use, simple in operation and the like.

Description

technical field [0001] The invention relates to a writing implement, in particular to a recyclable neutral pen core. Background technique [0002] Type the Background Technical Description paragraph here. Gel refill is a very important member of stationery, and the consumption is huge. There are nearly 300 million students in my country at present, and each person needs 15 billion ones a week. The material of the gel pen refill is polystyrene or modified polystyrene, which is famous for its aging resistance and corrosion resistance. This is consistent with the principle that ultra-thin plastic bags are difficult to degrade. It basically takes 100 years to be buried in the soil. In order to degrade by itself; most nibs and inks often contain some heavy metal elements (such as nickel, chromium, lead, mercury, etc.). When the refills are discarded at will, these substances will accumulate in the soil and cause great pollution to the environment. When polystyrene is incinera...
