Description

Technical Field

[0001] The utility model relates to the technical field of stationery, in particular to an arc-shaped rolled core ink storage bottle structure and an ink storage pen. Background Art

[0002] Highlighters, watercolor pens, whiteboard markers, and permanent markers are all common stationery items with coiled core ink storage. Traditional ink storage pens typically include a pen bottle, a pen cap, and an end cap. The pen bottle end cap is connected to one end of the pen bottle. The end cap and pen bottle are connected to form an inner cavity, in which an ink tube is installed. The inner wall of the pen bottle is formed with multiple reinforcing ribs, and the ink tube is clipped between the multiple reinforcing ribs to keep the ink tube fixed relative to the pen bottle. The end cap is also provided with a pen tip. One end of the pen tip protrudes from the end of the pen bottle and can be used for writing. The other end is inserted into the ink tube, allowing ink to enter the pen tip. The pen cap is placed on the end cap.

[0003] Existing pen bottles are typically made using injection molding, a process that uses a lot of materials, is expensive, and offers limited styles. Furthermore, due to the tapered neck design, injection molding can easily lead to problems such as mold release deformation, uneven and rough surfaces, and inward dents in the finished product. Blow molding has emerged to address these issues, but because blow molding involves an integrated molding process, it's impossible to form reinforcing ribs on the inner wall of the pen barrel. This prevents the ink tube from remaining securely in place within the pen bottle, causing it to easily wobble.

[0004] If the ink tube is directly in contact with the bottom of the pen bottle, although the ink tube can be fixed inside the pen bottle without shaking, this fixing method causes the end of the ink tube to be sealed by the bottom of the pen bottle, which will cause the airflow at both ends of the ink tube to be blocked, affecting the ink flow of the ink storage pen.

[0029] Example 1

[0030] Please refer to Figure 1-Figure 3 , Figure 1 This is a three-dimensional diagram of the arc-shaped rolled core ink storage bottle structure. Figure 2 This is a cross-sectional view of the arc-shaped rolled core ink storage bottle structure. Figure 3This is another cross-sectional view of an arc-shaped rolled core ink storage bottle structure. This embodiment provides an arc-shaped rolled core ink storage bottle structure, which includes a bottle body 1 and an arc-shaped limiting portion 2. Specifically, a bottle mouth 10 is formed at one end of the bottle body 1. The interior of the bottle body 1 is hollow and forms a storage space 11, and the bottle mouth 10 is connected to the storage space 11. The bottle mouth 10 is used to connect the interior and exterior of the bottle body 1. During use, the ink tube 3 and other items can be loaded into the storage space 11 through the bottle mouth 10. The arc-shaped limiting portion 2 is protruding from the interior of the end of the bottle body 1 opposite the bottle mouth 10 and is used to limit the position of the ink tube 3. Specifically, the arc-shaped limiting portion 2 includes a first arc-shaped limiting member 21, which is protruding from the bottom of the bottle body 1 and is located on one side of the bottom of the bottle body 1. A limiting space 23 is formed between the opposite ends of the first arc-shaped limiting member 21 and the two side walls of the bottle body 1. When the end of the ink tube 3 extends into the limiting space 23, the ink tube 3 is sandwiched between the side wall of the bottle body 1 and the first curved limiting member 22, thereby limiting the end of the ink tube 3 within the limiting space 23. An air passage 24 is formed between the first curved limiting member and the side wall of the bottle body opposite the first curved limiting member. The air passage 24 is respectively connected to the two limiting spaces 23, the accommodating space 11, and the bottle mouth 10.

[0031] The confined space 23 accommodates the end of the ink tube 3 extending into the bottle body 1. The air passage 24 ensures air circulation at the end of the ink tube 3 extending into the bottle body 1, preventing the end of the ink tube 3 from directly abutting the inner wall of the bottle body 1. This would prevent air from entering the end of the ink tube 3, leading to air flow failure at opposite ends of the ink tube 3 and causing ink flow problems. During use, the end of the ink tube 3 extending into the bottle body 1 is located in the confined space 23, and the end of the ink tube 3 extending into the bottle body 1 is exposed to the air passage 24, ensuring that the air pressure inside the ink tube 3 is consistent with the air pressure outside the ink tube 3. In actual use, this can avoid problems with ink flow problems caused by inconsistent air pressure inside and outside the ink tube 3.

[0032] In actual use, the first curved stopper 21 protrudes from the bottom of the bottle body 1. The height of the first curved stopper 21 gradually decreases from the center to the ends, forming a lower position at each end of the first curved stopper 21. If the ink tube 3 has a certain length, if the ink tube 3 abuts the highest point of the first curved stopper 21, the ink tube 3 will not be fully accommodated within the bottle body 1. One end of the ink tube 3 can only extend into the limiting space 23, causing the ink tube 3 to be tilted inside the bottle body 1. One end of the ink tube 3 is trapped between the first curved stopper 21 and the inner wall of the bottle body 1, keeping the ink tube 3 fixed. This ensures that the ink tube 3 remains relatively fixed to the bottle body 1 without the need for reinforcing ribs inside the bottle body 1. This prevents the ink tube 3 from swaying inside the bottle body 1, which could cause it to wobble.

[0033] It should be noted that the arc-shaped rolled core ink storage bottle structure in this embodiment can be applied to ink storage pens such as fluorescent pens, watercolor pens, whiteboard pens, and markers, and has the same beneficial effects.

[0034] Furthermore, the arc-shaped limiter 2 also includes a second arc-shaped limiter 23. The second arc-shaped limiter 23 is protruding from the bottom of the bottle body 1, and the first arc-shaped limiter 21 and the second arc-shaped limiter 22 are respectively disposed on opposite sides of the bottle body 1. A limit space 23 is formed between the sides of the first arc-shaped limiter 21 and the second arc-shaped limiter 22 and the inner wall of the bottle body 1. The airway is located between the first arc-shaped limiter 21 and the second arc-shaped limiter 22. Due to the spacing between the first arc-shaped limiter 21 and the second arc-shaped limiter 22, an airway 24 is naturally formed between the first arc-shaped limiter 21 and the second arc-shaped limiter 22.

[0035] When the end of the ink tube 3 extends into the limiting space 23, the ink tube 3 is sandwiched between the side wall of the bottle body 1 and the first curved limiting member 22 and the second curved limiting member 23, thereby limiting the end of the ink tube 3 within the limiting space 23. The first curved limiting member 22 and the second curved limiting member 23 provide support for the ink tube 3, thereby improving the stability of the connection between the ink tube and the bottle body.

[0036] Furthermore, the first curved stopper 21 is extruded inward from one side of the bottom of the bottle body 1, and the second curved stopper 22 is extruded inward from the other side of the bottom of the bottle body 1, so that the first curved stopper 21 and the second curved stopper 22 are arranged opposite each other. In this way, the first curved stopper 21 and the second curved stopper 22 are integrally formed with the bottle body 1, effectively reducing material costs, simplifying the production process, and effectively improving production efficiency.

[0037] In addition, the bottle body 1 includes a connecting portion 12 and a receiving portion 13 . The connecting portion 12 is connected to one end of the receiving portion 13 , and the connecting portion 12 and the receiving portion 13 are in communication. The bottle mouth 10 is provided at one end of the connecting portion 12 away from the receiving portion 13 .

[0038] The connecting portion 12 includes a first connecting structure 121 and a second connecting structure 122. One end of the first connecting structure 121 is connected to the second connecting structure 122, while the end of the second connecting structure 122, distal from the first connecting structure 121, is connected to the accommodating portion 13. Furthermore, the outer diameter of the second connecting structure 122 gradually increases as it moves away from the first connecting structure 121, forming an inclined guide surface. The bottle mouth 10 is formed at the first connecting structure 121.

[0039] The outer wall of the first connecting structure 121 is provided with a threaded structure, so that it is easy to connect with the end cap 4 of the ink reservoir pen.

[0040] Example 2

[0041] refer to Figure 4-Figure 6 , Figure 4 This is a three-dimensional diagram of the arc-shaped rolled core ink storage bottle structure of this embodiment. Figure 5 is a cross-sectional view of the bottle body of this embodiment, Figure 6 This is another cross-sectional view of the bottle body in this embodiment. This embodiment differs from the first embodiment in that the accommodating portion 13 includes a first accommodating unit 131 and a second accommodating unit 132. One end of the first accommodating unit 131 is connected to the second connecting structure 122, and the other end of the first accommodating unit 131 is connected to the second accommodating unit 132. The inner diameters of the first accommodating unit 131 and the second accommodating unit 132 are unequal, resulting in a boss structure 133 formed between the first accommodating unit 131 and the second accommodating unit 132. It should be noted that the boss structure 133 is used to modify the appearance of the bottle body 1 and provide a decorative effect. A first arc-shaped stopper 21 and a second arc-shaped stopper 22 are disposed on opposite inner sides of the second accommodating unit 132. A limiting space 23 is formed between the opposing ends of the first arc-shaped stopper 21 and the second arc-shaped stopper 22 and the side walls of the bottle body 1, respectively. An air channel 24 is located between the first arc-shaped stopper 21 and the second arc-shaped stopper 22. In actual usage scenarios, the end of the ink tube 3 is located in the limiting space 23 on either side, and the ends of the first arc-shaped limiting member 21 and the second arc-shaped limiting member 22 on the same side and the side wall of the second accommodating unit 132 limit the end of the ink tube 3 to prevent the ink tube 3 from shaking.

[0042] Example 3

[0043] Please refer to Figure 7 and Figure 8 , Figure 7 This is a cross-sectional view of the ink storage pen. Figure 8 Schematic diagram of the connection between the end cap and the refill. The present application also provides an ink storage pen, which includes the arc-shaped rolled core ink storage bottle structure of Example 1, and also includes an ink tube 3, an end cap 4 and a refill 5. Among them, the ink tube 3 is located in the accommodating cavity, and one end of the ink tube 3 is clamped into the limiting space 23 on one side, and the other end of the ink tube 3 is located in the connecting portion 12, so that the ink tube 3 is clamped and fixed in the bottle body 1. One end of the refill 5 is connected to the ink tube 3, and the other end thereof passes through the end cap 4 and is exposed outside the end cap 4. The end cap 4 is connected to the connecting portion 12 of the bottle body 1 through a threaded structure. The end cap 4 is used to cover the bottle mouth 10 to prevent the ink tube 3 in the bottle body 1 from falling out. There is an air gap 100 between the end cap 4 and the refill 5, and the air gap 100 is connected to the air channel 24 to ensure that the air pressure inside and outside the bottle body 1 remains consistent. It should be noted that the ink storage pen in this embodiment can be an ink storage pen with a rolled core ink tube, such as a fluorescent pen, a watercolor pen, a whiteboard pen, a marker, etc., and is not specifically limited here.

[0044] Furthermore, the pen body 40 includes a plurality of clamping ribs 41 and a body 40. The plurality of clamping ribs 41 are arranged around the inner wall of the end cap 4. The outer wall of the pen refill 5 abuts against the plurality of clamping ribs 41, and the pen refill 5 is fixed relative to the end cap 4 by the plurality of clamping ribs 41. An air gap 100 is formed between each pair of clamping ribs 41. The air gap 100 is connected to the air channel 24 in the bottle body 1 to ensure that the air pressure inside the bottle body 1 and outside the bottle body 1 remain consistent.

[0045] The ink storage pen further comprises a pen cap 6 , which is movably connected to one end of the bottle body 1 , and the pen cap 6 covers the end cap 4 and the pen core 5 is exposed at one end of the end cap 4 .
