Description

Writing instrument

The present invention relates to a writing instrument, particularly such as a color pen, a felt tip pen, a fiber tip pen, a ballpoint pen, a steel pen, a highlighter pen, a paint pen, a writing pen, a marker pen, and other types of writing instruments. Background technique

The writing tools on the existing market, although the form is complex and varied, the varieties are complete, but they all have the following common shortcomings: 1. The stock of writing ink is too small, and the frequency of changing new pens is very high. 2. Due to the structure of the writing instrument, if the filling exceeds the capacity of the writing ink itself, the pen is very easy to leak ink, so its leakage resistance is very poor, so the writing ink in the existing writing instrument The capacity of the liquid is a structure of low capacity. 3. When the writing instrument is stored for a long time, the writing ink in the ink storage chamber will naturally dry down. 4, especially the popular type of single-use writing instrument, often because of the rapid use of writing ink and the entire writing tool is still new when it has to be abandoned, so the utilization of the entire writing instrument is very low, Causes a great waste of resources.

There are also many inventors who have researched and improved existing writing tools in response to the above problems. For example, a writing instrument described in the WO 93/05966 patent application, and a writing instrument described in the Chinese Patent Publication No. WO1086173A. The two patent specifications disclose the use of two large and small ink reservoirs to solve the problem of too little storage ink. The disclosed technical solutions mainly divide the ink storage chamber into a large ink storage chamber and a small ink storage chamber by using a diaphragm element, and realize the opening and closing of the diaphragm element by the continuous expansion and contraction of the nib to realize the large ink storage chamber. The writing ink is supplied to a smaller ink reservoir. Thus, although the amount of liquid storage of the writing instrument can be increased, writing ink needs to be continuously replenished from a large ink storage chamber to a smaller ink storage chamber during writing, and thereafter, the writing ink is still It can continue to flow or penetrate into the tip of the pen, resulting in dripping during normal writing. This is mainly because the writing ink supplied to the smaller ink storage chamber by the large ink storage chamber is opened and closed by the continuous longitudinal movement of a movable member, which causes the pressure inside the ink storage chamber to automatically generate pressure, resulting in writing ink. The liquid is continuously pressed out to cause dripping.

There are also inventors who have improved on the drawbacks of the above structure. A writing instrument is disclosed in, for example, the patent application of WO 096/14998 (Publication No. CN1163589A), the basic structure of which is similar to the writing tool disclosed in the WO93/05966 patent and the Chinese patent CN1086173A. The main improvement is: the small liquid storage chamber adopts an annular elastic deformable member, the purpose of which is to compress the annular elastic deformable cavity on the supply passage from the nib during the forward movement of the nib and then expand the front It is mentioned that the leaking writing ink is sucked back. However, it has been found that during the forward movement of the marker pen, the liquid that flows or penetrates into the pen tip is too much to be sucked back in time, or sometimes the air is sucked back and the writing ink is rarely sucked back. Furthermore, for a writing instrument that uses a conventional ball-tip pen tip, since it is closed, the liquid that is infiltrated or pressed can hardly be sucked back, and therefore, there is still a drip phenomenon.

The writing instrument of the present invention comprises a pen tip 1 for applying writing ink on a writing medium, a first ink storage chamber 2 for supplying writing ink to the pen tip 1, and a fixing base 20 for fixing the pen tip 1 Also included is at least one additional ink reservoir 3 (3') containing writing ink 13, and at least one opening device 4 (4,) for opening (punching) and guiding at least one additional ink reservoir 3 (T The middle writing ink 13 is electrically connected to the pen tip 1 to supply the writing ink 13 to the pen tip 1.

The additional ink reservoir 3 (3,) equipped with the writing ink 13 is a fully enclosed structure and is radially movable or rotatable along the first ink reservoir. An intake passage may also be included on the additional ink reservoir. In addition, the additional ink reservoir surface may be at least partially threaded, and may be arranged in a thread shape on a sleeve formed by the wall of the first ink reservoir extending in the opposite direction of the pen tip. Pick up. The bottom of the additional ink reservoir may also include a recess and be coupled to the opening means.

At least one additional ink reservoir containing writing ink may be disposed outside the first ink reservoir, at The upper or side or lower side of the first ink reservoir may also be at least partially disposed within the first ink reservoir. Further, the opening device is disposed outside the first ink storage chamber, above or to the side or below the first ink storage chamber, and may be at least partially disposed in the first ink storage chamber, and may also be disposed On the additional ink reservoir.

The technical solution of the present invention may further include: providing an ink containing device having an adsorption capability in the first ink storage chamber, so that the writing ink in the first ink storage chamber is adsorbed in the ink containing device, and the ink containing device is connected to the pen tip .

Preferably, the capacity of the first ink reservoir 2 and the writing ink 13 in the additional ink reservoir 3 may be equal or similar. The first ink reservoir 2 and the writing ink 13 in the additional ink reservoir 3 may also be of the same or different colors to suit different writing needs.

The technical solution of the present invention can be written on any solid. The writing ink 13 may be water-soluble ink, ink (paint), alcohol ink or any other form of ink. In general, when writing ink and using water-soluble ink, it can be used as a writing pen (tap pen) to write on paper. When writing ink, ink or alcohol ink, it can be used as a marker pen, and the effect on writing on an object is better.

The following is an example of the case where the opening device disposed outside the first ink storage chamber is located above the first ink storage chamber - Embodiment 1: Referring to FIG. 1, the first ink storage chamber 2 containing the writing ink 13 is disposed outside. The additional ink tank 3 containing the writing ink 13 is located above the first ink storage chamber 2, and the additional ink tank 3 is a fully enclosed structure as a preferred structure, thus fundamentally ensuring that the additional ink tank 3 is disposed at The liquid leakage phenomenon does not occur when the first ink storage chamber 2 is outside, and it can be stored for a long time and is not easily dried.

An opening device 4 provided for opening (punching) and guiding the writing ink 13 in the additional ink tank 3 outside the first ink storage chamber 2 may be located above the first ink storage chamber 2, and the opening device 4 may be installed at the first The top portion of the ink storage chamber 2 may also be integrally or fixedly integrated with the top portion, the opening device 4 is connected to the additional ink tank 3, and the bottom portion 31 of the additional ink tank 3 may be provided with a recess 32. It is connected to the opening device 4. The bottom surface of the recess 32 is preferably made of an openable and thin plastic.

The opening device 4 may include an opening member 41 and an ink introducing device 42. The ink ejector unit 42 is disposed in the opening member 41, and the ink priming device 42 is in communication with the pen tip 1. The damper member 41 is inserted into the recess 32 and is sealingly connected to each other, so that the top of the first ink accommodating chamber 2 is closed, preventing the top of the first ink accommodating chamber 2 from having the ink absorbing device 42 or the first The liquid leakage of the second ink wick 11 causes a liquid leakage phenomenon, so that the writing ink 13 in the first ink storage chamber 2 can be normally supplied to the pen tip 1. Referring to Fig. 1, the pen tip 1 may include a second wicking core 11 and balls 12, and the second wicking core 11 is connected to the squeezing device 42.

The ink priming device 42 may be an priming liquid core 421, and at least a portion of the priming liquid core 421 is exposed or exposed on the inlet of the opening member 41, so that the opening member 41 opens the additional ink tank 3 to facilitate the attraction of the ink wick 421 The writing ink 13 in the ink tank 3. The wicking core 421 can be made of a material having an adsorption capacity (capillary attraction) such as a fiber core with a gap or a felt core or the like. Referring to FIG. 1 and FIG. 2, the wicking core 421 and the opening member 41 may be closely matched to each other, and the ink reservoir 13 is prevented from moving from the ink priming solution after the additional ink tank 3 is moved (when operating). The cooperation between the core 421 and the opening member 41 leaks writing ink into the first ink storage chamber 2. The opening device 4 may further include a ventilation passage 43 which may be disposed in the opening member 41, and the ventilation passage 43 may be disposed on the inner wall of the opening member 41. The ventilation passage 43 may also be provided on the squeezing device 42; it may be disposed between the opening member 41 and the squeezing device 42; or may be disposed on the outer side of the opening member 41. When the writing ink 13 in the additional ink tank 3 is reduced in writing, air can be exchanged through the ventilation passage 43 to prevent the negative pressure from being generated in the additional ink tank 3, resulting in the ink set in the opening device 4. Device 42 is unable to direct writing ink to tip 1 . The ventilation passage 43 can be preferably a smaller slit or groove structure.

A slitted structure may also be provided on the additional ink reservoir, for example, an air inlet passage may be provided on the additional ink reservoir to exchange air through the air inlet passage when the writing ink is reduced in writing. The guiding ability of the ink guiding device is also improved. The inlet passage may be provided on the side wall of the recess in the bottom or bottom of the additional ink reservoir, with smaller slits or slots being preferred.

Referring to FIG. 2, when the original writing ink 13 of the first ink storage chamber 2 in FIG. 1 is used up, the socket 21 formed by extending in the opposite direction of the pen tip 1 in the first ink storage chamber 2 can be opened. The protective cover 6 is then moved downward (pressed) by hand to attach the ink reservoir 3, and the additional ink tank 3 is moved radially along the first ink storage chamber 2, so that the through-piece 41 on the opening device is pierced. The recess 32 on the bottom 31 of the ink tank 3 is attached, and then the protective cover 6 is reinstalled to prevent the additional ink tank 3 from being affected. Referring to the case where the recess is opened in Fig. 2, after the opening member 41 passes through the additional ink tank 3, the opening member 41 and the additional ink tank 3 are still tightly fitted to each other and connected in a highly sealed manner, and the ink wick 421 is attached. At least partially smoothly fed into the additional ink reservoir 3, causing the writing ink 13 in the additional ink reservoir 3 to communicate with the priming core 421 and then lead to the second wicking core 11 in communication therewith. The writing ink is continuously supplied to the pen tip 1 so that the writing instrument can achieve both high capacity and extended writing time, and the additional ink reservoir 3 or the additional ink tank 3 and the first ink storage chamber 2 or the tip 1 is easily solved. The leakage phenomenon occurs, causing the writing ink 13 in the additional ink tank 3 to be directly led to the nib 1 through the ejector core 421 and the second immersion liquid core 11, thus forming an equivalent ink reservoir and The writing ink in the first ink storage chamber supplies the writing ink to the pen tip 1 through its own ink-inducing line, and does not affect each other, thereby realizing the purpose of convenient and safe continuous writing.

The opening member 41 can be formed as a beveled or pointed structure for the purpose of allowing the recess 32 to be easily broken.

The jacket may be sleeved on the ink priming device 42 and/or the second priming core 11 passing through the first ink storage chamber 2, and when the writing ink in the first ink storage chamber 2 is used up, a cavity is generated. The outer sleeve can protect the writing ink in the additional ink tank 3 from being easily dried by the immersion device 42 or the second immersion liquid core 11.

The first ink reservoir and/or the additional ink reservoir are made of plastic, which makes processing easier and less expensive.

Referring to FIG. 1 and FIG. 2, a leak-proof device 22 having an adsorption capacity may be disposed between the first ink storage chamber 2 and the pen tip 1 for improving leakage resistance, and the first row may be disposed on the leak preventer 22. The air passage 220 may be used to discharge or enter air. A deflector 23 having an adsorption capacity may be disposed at an upper portion of the leak preventer 22, and the deflector 23 is connected to the first exhaust passage 220 of the leak preventer 22. For better structure, when subjected to changes in temperature and/or atmospheric pressure, the writing ink which overflows the excess portion through the immersion liquid core 421 or the second immersion liquid core 11 may be first absorbed by the deflector 23. Then, it is smoothly guided to the groove provided in the leak preventer 22 through the first exhaust passage 220, and the leakage preventing effect of the leak preventer 22 is improved. The deflector 23 can also be disposed on the leak preventer 22 Bottom. A fixing member (not shown) for fixing the deflector 23 may be provided on the deflector 23. The deflector 23 can be made of a fibrous material or a felt material or a sponge material or the like which has a strong adsorption ability.

A second exhaust passage 221 may be provided in the fixed seat 20 for assisting the timely discharge of the expanded air in the first ink storage chamber 2 or the additional ink tank 3 or allowing the exchange air to come in during writing.

Referring to FIG. 2, when the writing ink in the first ink storage chamber 2 is used up, even if the temperature and/or atmospheric pressure are changed, the air expanded in the first ink storage chamber 2 can only be toward the first exhaust passage. The 220 and the second exhaust passage 221 are discharged, thereby avoiding pressure on the additional ink tank 3 and the pen tip 1, that is, the pen tip 1 avoids liquid leakage, and the air in the additional ink tank 3 is subjected to temperature and / When the atmospheric pressure or the like changes, as in the case where the writing ink is filled in the first ink storage chamber 2, if the ink to be squeezed is also subjected to the deflector 23 and the leakage resistance The device 22 absorbs, so the dripping phenomenon is also avoided.

When the writing ink 13 in the additional ink tank 3 is used up, the additional ink tank 3 can also be taken out, and a new one of the writing ink 13 as shown in Fig. 33 or Fig. 34 or Fig. 39 or Fig. 40 can be exchanged. The fully enclosed additional ink reservoir 3 allows the writing instrument to be used multiple times, greatly reducing the cost of using the writing instrument. This embodiment can also be used as a replacement refill. This embodiment can be written on any solid. When the writing ink 13 is made of water-soluble ink, it can be used as a general writing pen. The effect of writing on paper is better, but it can also be written on the object; when the writing ink 13 is used with alcohol ink or ink, As a marker pen, writing on an object works better, but it can also be written on paper.

It is also possible that the additional ink tank 3 containing the writing ink 13 is in a free-standing state, freely stored independently outside the first ink storage chamber 2 (see Fig. 33) or separately stored in the socket member 21, such that A closure may be provided on the opening of the opening member 41 to prevent leakage of the first ink storage chamber 2, and in addition, a sharp projection may be provided in the recess 32 of the additional ink reservoir 3, when additional ink storage is required. When the ink 13 is written in the device 3, the closure can be first through (piercing) through the sharp protrusion, and then the opening member 41 is broken through the concave portion as shown in FIG. 2, thereby making additional ink storage. The writing ink 13 in the device 3 reaches the pen tip 1 through the immersion liquid core 421 and the second immersion liquid core 11.

Embodiment 2: Referring to FIG. 3, the squeezing device 42 is disposed in the opening member 41, and the priming device 42 may be an priming core 421. The opening device 4 may further include an opening member 41, an immersion liquid core 421, and The ventilation passage 43 and the leakage preventing member 44 are disposed between the opening member 41 and the immersion liquid core 421, so that the writing ink 13 in the additional ink tank 3 is smoothly supplied to the pen tip 1, so that the writing is smooth and the liquid leakage is not easy. . The leakage preventing member 44 prevents the writing ink 13 in the additional ink tank 3 from leaking into the first ink storage chamber 2, and also facilitates the installation of the ink guiding core 421 in the opening member 41. The ventilation passage 43 may be a slit or a groove structure. The ventilation passage 43 may be provided on the leakage preventing member 44; or may be provided on the inner side of the opening member 41.

Referring to FIG. 3 and FIG. 35, at least a portion of the surface of the surface of the additional ink tank 3 is threaded 30, and a threaded shape is also formed on the mouth of the socket member 21 formed by extending the first ink storage chamber 2 in the opposite direction of the pen tip 1. 210 can be connected with the threaded shape 30, and the user can only open the ink tank 3 by rotating, so that the opening device 4 can open the writing ink 13 in the additional ink tank 3, thereby avoiding inadvertent or child play. When the ink tank 3 is additionally opened (punch through) and liquid leakage occurs, the structure is more reasonable and safe. Referring to FIG. 4, when the original writing ink of the first ink storage chamber 2 in FIG. 3 is used up and the writing ink 13 in the ink tank 3 is required to be attached, the additional ink tank 3 is rotated by hand to make the external thread shape. 30 is screwed to the internal thread 210. At this time, the additional ink tank 3 can be rotated radially along the first ink storage chamber 2, so that the opening member 41 is opened to the additional ink tank 3, so that the additional ink tank 3 is The writing ink 13 supplies the writing ink 13 to the pen tip 1 through the ink priming device 42 and the second immersion liquid core 11. The arrangement of the thread 30 also prevents the additional ink reservoir 3 from falling off. When the writing ink 13 in the additional ink tank 3 is used up, a new fully enclosed additional ink tank 3 containing the writing ink 13 as shown in Fig. 36 can be replaced.

Embodiment 3: Referring to FIG. 5 and FIG. 39, at least a portion of the surface of the bottom portion 31 of the additional ink tank 3 may be threaded 310, and the first ink storage chamber 2 extends in the opposite direction of the pen tip 1 to form a socket. The bottom of the 21 is also provided with a thread 210 which can be connected to the thread 310 on the bottom 31 of the additional ink reservoir 3. A closing member 33 is provided in the through hole opened in the bottom portion 31 of the additional ink tank 3 to form a recess 32, and the closing member 33 may have a bead shape or a block shape. When the writing ink 13 in the ink tank 3 is required to be attached, the additional ink tank 3 is rotated to connect the external thread shape 310 to the internal thread shape 210', so that the additional ink tank 3 is along the first ink storage chamber 2. Radial rotation causes the opening member 41 to open (open) the ball-shaped closure member 33, so that the writing ink 13 in the additional ink tank 3 passes through the ink-receiving liquid core 421 and the second ink-receiving liquid core having the adsorption capacity. 11 is connected to the pen tip 1. Referring to Figure 5, the nib 1 can include a second wicking core 11. It is also possible to use a slit type nib or the like. The writing instrument of this embodiment can be written on any solid. The writing ink 13 uses water-soluble ink, which can be used as a general writing pen. The effect of writing on paper is better, but it can also be written on an object. The writing ink 13 is made of alcohol ink or ink and can be used as a marker pen. Writing on objects is better, but it can also be written on paper. This embodiment can also be used as a replacement refill.

When writing is required, the writing ink 13 naturally in the first ink storage chamber 2 near the pen tip 1 first supplies writing ink to the pen tip 1, and the additional ink tank 3 is sealed to at least part of the surface of the opening member 41. . Moreover, the opening member 41 and the squeezing liquid core 421 in the opening device are also closely fitted to each other. Or the structure shown in FIG. 3 further includes providing a ventilation passage 43 and a leakage preventing member 44 between the opening member 41 and the ejector core 421, thus solving the additional ink tank 3 or the additional ink tank 3 A liquid leakage phenomenon that easily occurs between the first ink storage chamber 2 and the additional ink reservoir 3 is prevented from leaking the writing ink into the first ink storage chamber 2. Therefore, the writing ink 13 in the additional ink tank 3 does not affect the first ink storage chamber 2 to normally supply the writing ink to the pen tip 1, and when the writing ink 13 in the first ink storage chamber 2 is used up, the additional storage is performed. The writing ink 13 in the ink unit 3 then automatically supplies the writing ink to the pen tip 1 through the ejector core 421 and the second immersion liquid core 11, thus forming an equivalent of the additional ink reservoir and the first ink reservoir. The writing ink in the cavity supplies the writing ink to the pen tip 1 through its own ink-inducing line, which does not affect each other, thereby saving the user the process of moving the additional ink reservoir to achieve the purpose of continuous safe writing and anti-drip.

It is also possible to provide an ink containing device 25 (see the ink containing device shown in Fig. 19) in each of the first ink storage chamber 2 and the additional ink tank 3 to make the first ink storage chamber 2 and the additional ink tank 3 The writing inks are each adsorbed in one of the ink containing devices 25, thus forming not only the ink containing means in the first ink storing chamber 2 supplies the writing ink to the pen tip 1, but also the ink in the additional ink tank 3. The device can also supply writing ink to the pen tip 1. When the writing ink adsorbed in the ink containing device provided in the first ink storage chamber 2 is used up or is not used much, the writing ink adsorbed in the ink containing device provided in the additional ink tank 3 can also be passed through The ink device 42 and the second immersion liquid core 11 continue to supply writing ink to the pen tip 1. Such changes or modifications are within the scope of the inventive concept and are intended to be within the scope of this patent.
