Description

Long service life marking pen with secondary liquid storage sleeve

Technical Field

The invention relates to cultural writing articles, in particular to a marking pen or a whiteboard pen for writing.

Background

In cultural writing articles, marker pens are widely used as marking tools on various material packaging boxes, glass, ceramic and metal products, wood and the like, and white board pens are widely used as teaching and office tools for writing on white boards. Ink pens are classified into water-based pens, oil-based pens, gel-ink pens and medium-oil pens.

The ink used in the water pen is pure water, and is generally used on a substrate with strong absorptivity, such as paper. It can be erased even if written on a non-absorbent substrate such as a whiteboard. The writing paper has no back mark, and has the advantages of good writing hand feeling and writing quality. The water pen comprises: pens, ordinary fountain pens, sign pens, highlighters, watercolor pens, white board pens, and the like.

The ink used by the oil pen is oil, is not easy to fade, is insoluble in water, and is not easy to render and dissolve when meeting water. The oil pen can write on the absorbing and non-absorbing substrate plane and is difficult to erase. The oily pen includes: ball point pens, marker pens, and the like.

The ink used by the gel pen has the property between that of a water-based pen and that of an oil-based pen, the storage time of writing marks is longer than that of the water-based pen and is close to that of the oil-based pen, the writing marks are not easily dissolved when meeting water, and the writing hand feeling and the writing quality are far better than those of the oil-based pen. Gel-ink pens, such as gel-ink ball-point pens, combine the advantages of fountain pens and ball-point pens and are often used when writing certain documents that need to be preserved.

The medium oil pen is a neutralized product of a neutral ball pen and an oil ball pen. The viscosity of the ink of the medium-density ball pen is low and is close to that of a neutral pen, so that the characteristics of smooth writing, quick drying after writing and easy cleaning of leakage liquid of the neutral pen are kept, and the defects of over-viscosity and insufficient smoothness of writing of the oil-density ball pen ink are avoided. The medium oil pen is also called medium oil ball pen.

In all the pens, the marker pen, the mark pen, the white board pen and the water color pen which have the characteristic of large pen point exposure area, particularly the marker pen, the mark pen and the mark pen with oily ink and low viscosity, have the characteristics of serious solvent volatilization and dry ink during the writing process, particularly when a pen cap is lost or is forgotten to tightly cover the pen cap, and greatly shorten the service life of the pen due to the strong volatility of the ink. Therefore, the marker pen, the white board pen and the like which can effectively inhibit the volatilization rate of the printing ink and have the characteristic of long service life are not only convenient for a writer to use and can increase the comfort level and the mood delight degree during use, but also can play the roles of reducing waste, making the best use of things and protecting the environment, and have important practical significance to consumers and the whole society.

Detailed Description

The invention is further illustrated by the following figures, examples and comparative examples.

Examples

Referring to fig. 1, a schematic diagram of the overall structure of the embodiment of the present invention is shown. The marking pen with the long service life is characterized in that a secondary liquid storage sleeve (24) is added on the outer side of a primary core storage tube (22), the inner wall of the secondary liquid storage sleeve (24) and the outer wall of the primary core storage tube (22) share a thin layer, the primary core storage tube and the secondary liquid storage sleeve share a thin layer wall (25), and the thickness of the outer wall of the secondary liquid storage sleeve (24) is the same as that of the outer wall of the primary core storage tube (22) without the sleeve.

The invention relates to a marking pen with long service life, which is characterized in that a small hole with proper diameter is arranged on the wall of a pen rod pipe (21) opposite to a puncturing nail (242), and a hitting nail ball (214) is arranged in the small hole.

Furthermore, the material of the nail striking ball embedded in the wall of the pen holder tube (21) can be made of glass, hard plastic, steel or other metals.

Furthermore, a nailing ball position indication label (213) is arranged on the outer wall of the pen rod tube (21) embedded with a small hole of the nailing ball (214). The nail-hitting ball position indicator (213) may be a sticker printed with a pattern of a circular hole size, a pattern printed on the pen shaft tube (21) for facilitating the recognition of the circular hole, or a film cover printed with a pattern of a circular hole recognition.

The invention relates to a marking pen with long service life, which is characterized in that a pen core fixing piece (27) is arranged at the tip end of a primary core storage tube (22), and a pen core fixing piece (26) is arranged in a first-stage narrowing conical table at the end of a very thin pen head of a pen holder tube (21). The specific structure of the refill fixing piece (27) and the refill fixing piece (26) is shown in figures 8 and 9.

When the ink in the primary storage tube (22) is consumed due to writing or the pen cap is opened and volatilized completely until writing is not smooth, the nail striking ball position indicating label (213) is pressed by the tip of an iron nail or a ball-point pen, so that the nail striking ball (214) moves downwards, the piercing nail (242) is pressed, the common inner wall between the secondary liquid storage sleeve (24) and the primary storage tube (22) is pierced by the downward movement, the thin-layer wall (25) is shared by the primary storage tube and the secondary liquid storage sleeve, and the ink stored in the secondary liquid storage sleeve (24) is absorbed by the liquid storage core (23) in the primary storage tube (22) through capillary action, so that the secondary ink supplement effect is achieved.

By taking the double-head marker pen of morning light MG-2130 or SPM21302 as a comparison and calculating, as shown in a table of figure 10, as the narrowing cone frustum of the very thin pen head end and the length limit of the plastic pen point frame insertion cylinder of the thin pen head end are limited, the volume of the secondary liquid storage sleeve (24) which is designed to be the longest in the invention can occupy 84 percent of the volume of the primary liquid storage tube (22), thereby ensuring that the service life of the marker pen is greatly prolonged on the premise that the size of the pen body is not changed.

Comparative example

Fig. 2 is a schematic diagram of the overall structure of a conventional marker in the market, such as a morning light MG-2130 or SPM21302 dual-head marker. As can be seen, the pen core is a cylindrical liquid storage core with the length of 9cm and the diameter of 0.5cm, and the effective volume is 1.77cm³. When the marking pen is forgotten to cover the pen cap tightly after being used, the ink in the liquid storage core is volatilized quickly through the pen head exposed to the atmosphere, and a book can be led to be closed quicklyThe writing traces are delayed and discontinuous so that no traces are written out. Even if the marking pen is properly maintained and the pen cap is closed in time after use, the effective volume of the liquid storage core is far less than that of the liquid storage quantity in the embodiment, and the liquid storage quantity in the embodiment is 1.49+1.77=3.26 cm³The service life is also significantly lower than in the present embodiment.

Another great advantage of the present invention is that in emergency situations where a new marker cannot be replaced, a relatively long continuous service life can be obtained by merely using a readily available iron nail or a ballpoint pen tip to squeeze the nail-striking ball position indicator without causing any error; the pen cap can be used for training a user while compensating the consequences of the user caused by errors, and the user can be noticed to cover the pen cap tightly in time after use.

The above description is only exemplary of the invention as applied to a marker and is not intended to limit the scope and application of the invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the invention should be included in the protection scope of the invention.
