Ink bottle

Abstract

The invention provides an ink bottle. The ink bottle comprises an upper bottle body, a lower bottle body, a glass liner, a needle cylinder, a base and a spring. The upper bottle body is movably connected to the lower bottle body in a sleeved manner, and the glass liner is arranged in the space enclosed by the upper bottle body and the lower bottle body; the opening portion of the glass liner is connected with the opening portion of the upper bottle body, the middle portion of the glass liner is provided with an inverted-T-shaped compressible folding and bouncing structure, and the bottom of the lower bottle body is connected with the base; the top of the lower bottle body is provided with a limiting portion for partitioning the inverted-T-shaped middle portion of the glass liner; the spring is arranged between the base and the bottom of the lower bottle body; the needle cylinder comprises a supporting seat located on the upper portion of the needle cylinder and a supporting and jacking seat located on the lower portion of the needle cylinder; the supporting and jacking seat is internally provided with a connection seat, a needle pipe and a hose, the lower end of the needle pipe is inserted into a hollow channel of the connection seat and communicates with the interior of the glass liner through the hose, and the upper end of the needle pipe penetrates through the supporting seat to communicate with the outside; and the lower end of the supporting and jacking seat abuts against the bottom of the glass liner. The ink bottle has the advantages that the ink bottle is simple in structure, low in cost, attractive in appearance and has two functions of ink return and ink injection.

Description

Technical field [0001] The invention relates to stationery, and more specifically, to an ink bottle. Background technique [0002] At present, the commonly used fountain pens are ink-absorbing fountain pens. After this fountain pen is inked, the tip of the pen must be stained with ink, which needs to be wiped, which makes people feel inconvenient. In addition, when the ink bottle is full, it will absorb ink. Ink can also easily stain the pen barrel. In addition, although the previous generation ink bottle (patent name: anti-overfill bottle, patent number: 201310113631.X) designed by the inventor has solved the above problems, the following problems have appeared in the market: [0003] (1) When the outside temperature is high, the ink will overflow from the needle tube when the bottle cap is removed, which is easy to cause waste and pollution; [0004] (2) During transportation, when the ink filling bottle is upside down or when the ink filling bottle is subjected to strong vibrati...

AI Technical Summary

Problems solved by technology

[0003] (1) Ink may overflow from the needle tube when the bottle cap is removed when the external temperature is high, which is likely to cause waste and pollution;

[0004] (2) During transportation, when the ink filling bottle is turned upside down or when the ink filling bottle is subjected to strong vibration, the ink in the bottle will overflow;

[0005] (3) When the ink pen is not used for a long time, due to the evaporation of part of the ink at the end of the pen, this will cause the ink concentration in the pen tank to be too high, which will easily cause blockage of the ink path and poor writing

However, the existing ink filling bottle cannot realize the above-mentioned function of returning ink and changing ink;

[0006] (4) If there is a lot of ink stored in the pen tank itself, when refilling ink, it will cause part of the ink to overflow, resulting in waste and pollution
