Description

Refillable straight liquid roller ball pen and ink bottle

technical field

The patent of the present invention relates to a hard pen type writing tool, in particular to a straight liquid roller ball pen and an ink bottle that can be repeatedly filled with ink.

Background technique

At present, the most widely used gel pen on the market is a disposable gel pen. The straight liquid type ballpoint pen has gradually entered everyone's field of vision due to its large ink storage capacity and good ink fluidity. However, there are only two types of straight-liquid roller-point pens, one-off and replaceable ink sac type, and the waste of the pen body still needs attention. The existing ink filling methods still have some deficiencies, the operation technology is cumbersome and troublesome, and some technologies are limited to specific places, and it is difficult to expand the use. Specifically, there are the following problems: 1. The ink storage is limited. The ink sac has a small amount of ink at one time, and the ink sac is replaced frequently, resulting in a large amount of white garbage; 2: The operation is cumbersome, and the tip of the pen is stained with ink every time the ink is filled, which needs to be wiped off with a paper cloth, which is time-consuming and laborious; 3: Too many parts, easy to get rid of Lost; four: easy to leak ink. In response to the above problems, we improved the internal structure of the pen and designed a dedicated ink bottle. Compared with the ordinary ball-point pen, the ball-point pen adopts an internal spring device, which overcomes the problem of non-refilling of the ball-point pen, and the ink storage capacity is about ten times that of the ink sac. The annual amount of white pollution from roller-point pens.

The ink bottle is composed of a syringe and a bottle body. The main part of the syringe is fixedly connected by a pull rod and a rubber ring, and the bottom end of the tube body is fixedly connected with the needle tube. The main part of the bottle body is composed of a bottle cap, a bottle wall and an ink bag. A sealing ring is adhered to the top of the bottle mouth of the bottle body, and the bottle body and the syringe are connected in a threaded manner.

1: A design of a refillable straight liquid roller ball pen and an ink bottle, characterized in that: the main body of the pen is composed of a scale regulator (2), a spring (4), a piston (5), a porous screen tube (8) Fixed connection, the screw cap (10) and the pen shell (7) are connected by thread, the rubber ring (12) is embedded in the top of the screw cap screw, and the ink tank (9) is between the porous screen tube and the pen shell. part, the water diversion core (3) is connected to the pen tip (1) and then nested in the center of the scale regulator (2), the annular bayonet (6) and the pen shell (7) are integrated devices, and the annular bayonet (6 ) divides the pen into upper and lower parts.

The ink bottle is composed of a syringe and a bottle body, the main part of the syringe is fixedly connected with the piston (14) by the pull rod (13), and the bottom end of the tube body is fixedly connected with the needle tube (16). The main part of the bottle body is composed of a syringe (12), a bottle wall (18) and a bottle cavity (17). A sealing ring (15) is adhered to the top of the bottle mouth of the bottle body, and the bottle body and the syringe are connected in a threaded manner.

The present invention has the following technical effects: 1. Compared with the common ball-point pen, the ball-point pen adopts an internal spring device, which overcomes the problem that the ball-point pen cannot be repeatedly filled with ink. 2. The ink storage capacity is about ten times that of the ink sac. It has a long service life and is easy to use. The ink filling process is clean and does not overflow, which effectively reduces the annual white pollution of the ballpoint pen. 3. The perfect combination of the syringe and the ink bottle not only meets the needs of the pen body for inking, but also ensures the tightness of the ink bottle.

Detailed ways

As shown in the following figures, a design of a refillable straight liquid rollerball pen and an ink bottle, the main body of the pen consists of a scale regulator (2), a spring (4), a piston (5), a porous screen type The tube (8) is fixedly connected, the screw cap (10) and the pen shell (7) are connected by thread, the rubber ring (11) is embedded in the top of the screw cap screw, and the ink tank (9) is a porous screen tube and the pen shell. The part between the water diversion core (3) and the pen tip (1) is nested in the center of the scale regulator (2) after connecting, the annular bayonet (6) and the pen shell (7) are integrated devices, and the annular bayonet (7) is an integrated device. (6) Divide the pen into upper and lower parts.

The ink bottle is composed of a syringe and a bottle body, the main part of the syringe is fixedly connected with the piston (14) by the pull rod (13), and the bottom end of the tube body is fixedly connected with the needle tube (16). The main part of the bottle body is composed of a syringe (12), a bottle wall (18) and a bottle cavity (17). A sealing ring (15) is adhered to the top of the bottle mouth of the bottle body, and the bottle body and the syringe are connected in a threaded manner.

When filling ink, unscrew the screw cap (10), under the action of the spring (4), the piston (5) moves upward, and stops at the annular bayonet (6), the piston (5) and the annular bayonet (6) The lower part of the ink tank is closed and isolated from the atmosphere, and the upper part is communicated with the atmosphere. Pull the lever (13) on the ink bottle syringe to fill the syringe with ink, and then inject the ink into the porous screen tube (8) through the pen port; Under the pressure of the screw cap (10), the piston moves downward and separates from the bayonet, and the lower part is connected to the upper part.
