Abstract

The present invention relates to a fountain pen, particularly to a fountain pen which uses a pressing, ink-dripping and permeating mode for preventing ink from being rapidly volatilized so as to save ink consumption. The fountain pen comprises a pen pipe, an ink pipe arranged in the pen pipe, a pressing device arranged on the upper end of the pen and a pen head arranged on the lower end of the pen. The lower end of the ink pipe is in a conical funnel shape and is positioned on a limiting base in the pen pipe, a dripping hole of the lower end of ink pipe has a certain distance with the upper end of the pen core of the center of the pen head, and an absorbing body of the pen head part does not fully fill the space between the pen head and the ink pipe. Thus, when the fountain pen is not used, the ink can not be dripped into the pen head, and the ink can be dripped into the pen head for writing only by pressing the pressing device.

Description

Fountain pen

The present invention relates to a kind of fountain pen, particularly a kind of dependence push drip China ink and penetration theory and avoid ink to volatilize rapidly and cut off the water supply, and can save the fountain pen of ink consumption.

Fountain pen of the prior art, as shown in Figure 1, comprise one up and down both ends open hollow tube (10), be located at sponge column (20) in the described hollow tube (10) and the nib parts such as (30) of being located at described hollow tube (10) lower end.Be inserted with pen core (31) in the nib (30), described pen core (31) extends upwardly to sponge column (20) inside always, and its other end then is stretched on the outside of nib (30).Ink is injected in the sponge column (20) by hollow tube (10) upper end open, and shut the upper end open of described hollow tube (10) with loam cake (11), pen core (31) absorbs the ink in the sponge column (20), after pen core self is full of ink, can write.

But this traditional pen from the beginning has following shortcoming:

1) owing to the sponge column (20) that is filled ink is bigger, and constantly with ink bleed to pen core (31), making has too much ink to accumulate in pen core (31) and to dirty, thereby gather more ink easily in pen core (31) end, cause to write and have some setbacks, even make ink droplet on paper or in the inflow pen cap, very inconvenient.

2) because sponge column (20) and air contact-making surface are bigger, make ink minimizings of volatilizing easily, thereby user's ink of having to often add, otherwise, because of the ink volatilization, can cause the black phenomenon of breaking, and often add ink, be very inconvenient to the user.

3) because sponge column (20) is longer, ink infiltrates into the bottom after injecting the sponge column upper end more gradually, must be more so once add the China ink amount, and just can make the sponge column bottom be full of ink and absorbed by pen core.Like this, not only ink consumption is bigger, and it is oversize to add the China ink time, and is concerning the user, real in losing time.

Main purpose of the present invention provides a kind of dependence and pushes and drip China ink and penetration theory and avoid overrun volatilization and can save the fountain pen of ink consumption of ink.

Another object of the present invention provides a kind of novel fountain pen, and this fountain pen is easy to use, needn't add ink.

Another purpose of the present invention provides a kind of novel fountain pen, and this stylographic pen core can promptly absorb ink and don't can gather ink in the pen core lower end, thereby writes Channel Group, and China ink can not break again.

Fountain pen of the present invention comprises the hollow shaft of a writing brush of a both ends open, and shaft of a writing brush inside front is formed with a back-up ring, and the below is formed with a limit base.An ink barrel of filling ink in advance runs through the back-up ring of described shaft of a writing brush inside front and is located on the limit base of below.End closure on the described ink barrel, lower end are formed with a tiny hole.The spring that ink barrel upper end sheathed is located on the back-up ring, a compression leg runs through the sleeve of installing in described shaft of a writing brush upper end open, and the compression leg lower end props up the upper end of ink barrel.Shaft of a writing brush lower end is installed on a nib, is provided with an absorber in the nib, and a pen core is arranged in the described absorber, and the pen core upper end passes behind the absorber and the hole of dripping of ink barrel keeps a determining deviation.When pushing described compression leg, ink barrel is subjected to downward extruding, and its ink inside just splashes into described absorber, is absorbed bulk absorption.Because the absorber volume is less, very easily saturated, so after pen core promptly is absorbed the interior ink bleed of body, can write.When not clamping down on compression leg, because a hole of ink barrel lower end is very little, because the attached outstanding power and the cohesiveness of molecular ink, ink can not splash in the absorber.Like this, under unused state, ink can not splash into absorber, can not gather too much ink in the pen core lower end.Fountain pen of the present invention has following advantage:

1) fountain pen of the present invention has a compression leg of pushing usefulness, pushes once, promptly has a melted ink to splash in the absorber.Behind the absorbent body ink, with ink bleed to pen core, for writing.If do not push compression leg, then ink can not drip, thereby when not using, can not produce the too much phenomenon of long-pending China ink in the pen core lower end.

2) because the absorber length in the nib is shorter, and ink absorption rate is strong, but rapid permeability to pen core, thereby fluent writing.

3) owing to after pushing, drip a melted ink at every turn, can make absorber inhale full ink basically, be enough to pen core supply ink, thereby the ink consumption be less.Be filled in the ink barrel owing to ink again, very little with the air contact-making surface, so not volatile.Therefore generally speaking, exhausted amount of ink reduces, and has played the effect of saving ink.

4) ink is to irritate in advance to be stored in the ink barrel, when ink uses up in the pipe, as long as change a new ink barrel, needn't change a lot of times of expense and remove to add ink.

Below with reference to all accompanying drawings, the present invention is described in further detail.
