CN201353926Y - Gel ink pen with without refill - Google Patents

Abstract

The utility model relates to a gel ink pen with without a refill, which comprises a penholder, a seal cover, a pen point and a pen cap. No refill is arranged in the penholder; a venthole is formed on the seal cover at the tail end of the penholder; a vent pipe is arranged in the seal cover; the inside diameter of the leak-proof vent pipe is very thin and neutral ink has higher viscosity, so that the venthole is ventilated, and the ink does not leak when the pen is arranged upside down. Therefore, negative pressure does not appear in the penholder; and the ink flows smoothly in writing. No venting notch is formed at one end of the pen point; and all parts are matched and sealed without air leakage. When the neutral ink in the penholder is used up, all that is needed is to open the seal cover and add the neutral ink in the penholder directly; and the gel ink pen can be used again. The gel ink pen dispenses with refills, is used conveniently, saves use cost and raw materials and is favorable for environmental protection.

Description

The centreless gel ink pen

Technical field:

The utility model relates to a kind of writing implement, and particularly a kind of centreless gel ink pen belongs to the cultural goods field.

Background technology:

Existing gel ink pen; its structure mainly comprises penholder, the cap for brush and replaces core; place improper or grip when falling accidentally at pen in ground; regular meeting makes for core and loses even can't write; in a single day used up for core, must go more to renew for core, old can only abandon for core; caused certain waste like this, and contaminated environment.

Another kind of as the disclosed novel gel ink pen of Chinese patent ZL200720088277.X, comprise penholder, nib, screw propulsion rod, plastic piston, spring, screen pack, and nib is connected with the penholder spiral, though they can suck ink and use repeatedly, but their internal structure relative complex, and cost of manufacture is higher.

The utility model content:

The purpose of this utility model is in order to overcome above deficiency, and providing a kind of can directly be filled into neutral inks in the penholder, can change for core; and easy to use, save cost of use, be beneficial to environmental protection; centreless gel ink pen simple in structure, that cost of manufacture is lower.

The purpose of this utility model is achieved through the following technical solutions: a kind of centreless gel ink pen, comprise penholder, capping, nib, the cap for brush, do not have in the described penholder for core, the capping of penholder tail end is provided with a passage, be provided with the breather pipe of an anti-leakage in the described capping, described nib one end does not have the breach of giving vent to anger, and each part is complementary, and is tightly connected.

The utility model is a kind of centreless gel ink pen, and it has been cancelled for core, and neutral inks directly is filled in the penholder; Because anti-leakage breather pipe internal diameter is very thin, and neutral inks has bigger stickiness, thus passage can ventilate, and can leakage when the pen inversion.Can keep so not occurring negative pressure in the penholder, printing ink is unobstructed fluent when writing.

The utility model compared with prior art has the following advantages: neutral inks can directly be filled in the penholder, does not need to change for core, and cost of manufacture is low, and is easy to use, and it is unobstructed fluent to write, and reduces expenses and raw material, also helps environmental protection.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Number in the figure: 1-penholder, 2-capping, 3-nib, the 4-cap for brush, 5-passage, 6-breather pipe.

The specific embodiment:

In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show the utility model centreless gel ink pen as Fig. 1, comprise penholder 1, capping 2, nib 3, the cap for brush 4, do not have for core in the described penholder 1, the capping 2 of penholder 1 tail end is provided with a passage 5, is provided with a breather pipe 6 in the described capping 2.Because anti-leakage breather pipe 6 internal diameters are very thin, and neutral inks has bigger stickiness, thus passage 5 can ventilate, and can leakage when pen is inverted, can keep so not occurring negative pressure in the penholder 1, printing ink is unobstructed fluently when writing.Described nib 3 one ends do not have the breach of giving vent to anger, and each part is complementary, and it is air tight to be tightly connected.When the neutral inks in the penholder 1 uses up, only need capping 2 is unpluged, neutral inks directly is filled in the penholder 1, can continue to use, it has been cancelled for core, and easy to use, saves cost of use and raw material, also helps environmental protection.

Claims (1)

1. centreless gel ink pen, comprise penholder (1), capping (2), nib (3), the cap for brush (4), it is characterized in that: do not have in the described penholder (1) for core, the capping (2) of described penholder (1) tail end is provided with a passage (5), be provided with a breather pipe (6) in the described capping (2), described nib (3) one ends do not have the breach of giving vent to anger, and each part is complementary, and are tightly connected.
