Folding and resilience type ink injection bottle

Abstract

The invention provides a folding and resilience type ink injection bottle. The folding and resilience type ink injection bottle comprises a bottle body, a needle base and a liquid injection tube. The bottle body is provided with a bottle neck, and an opening is formed in the upper end of the bottle neck. A folding and resilience part is arranged between the bottle body and the bottle neck, and the bottom surface of the bottle body is an inwardly concave elastic surface. The needle base is fixedly arranged on the bottle neck. The needle base comprises a supporting base and a sleeve base, wherein the supporting base is located on the upper portion of the needle base, the pen body of an ink pen can be inserted in the supporting base, and the sleeve base is located on the lower portion of the needle base and fixedly sleeved with the liquid injection tube. The upper end of the liquid injection tube is exposed out of the supporting base and communicated with the outside. The lower end of the liquid injection tube abuts against the bottom surface of the bottle body, and the liquid injection tube is provided with a hose communicated with the interior of the bottle body. A first sealing part connected with the pen body of the ink pen in a sealing mode is fixedly arranged on the supporting base. The supporting base is provided with a ventilation hole making the interior of the bottle be communicated with the outside. By the adoption of the folding and resilience type ink injection bottle, ink return of the pen sac of the ink pen can be achieved before ink injection, and ink can be prevented from overflowing.

Description

technical field [0001] The invention relates to stationery, in particular to a folding ink bottle. Background technique [0002] At present, the fountain pen commonly used by people is an ink-absorbing fountain pen. After this fountain pen is inked, the nib part must be stained with ink, which needs to be wiped, which makes people feel inconvenient. In addition, when the ink in the ink bottle is full, the suction Ink can also easily stain the barrel. [0003] In addition, there is also a kind of ink-filling type ink bottle on the market, which is used to inject ink into the fountain pen liquid storage tube. After repeated tests by the applicant, the following problems still exist: [0004] (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; [0005] (2) During transportation, when the ink filling bottle is turned upside down or when the ink filling bottle is subjected ...

AI Technical Summary

Problems solved by technology

[0004] (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;

[0005] (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;

[0006] (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;

[0007] (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
