It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0033] In the prior art, CN214523004U discloses a pen case and a marker pen, wherein the pen case includes a pen holder and a pen cap, wherein the pen holder includes a pen body and a pen tip, wherein the pen tip is connected to the pen body by a thread, wherein the outer surface of the pen tip and the inner surface of the pen cap are provided with protrusions and grooves correspondingly, and the protrusions and grooves are engaged with each other so that the pen cap can drive the pen tip to rotate relative to the pen body. In this structure, since the protrusions are formed on the inner edge of the pen cap or the outer edge of the pen tip, and the grooves are narrow and long, when the pen tip is removed, both the protrusions and the grooves need to bear lateral forces, and the protrusions or the grooves are prone to breakage after long-term use.

[0034] Based on the above problems in the prior art, the utility model provides a pen case 10, such as Figures 2 to 4 , Figure 6 to Figure 7 As shown, the pen housing 10 includes a pen cap 100, a pen tip 101 and a pen body 102; the pen tip 101 is threadedly connected to the pen body 102;

[0035] At least one first bonding group is formed on the outer edge of one end of the pen tip 101 connected to the pen body 102; the first bonding group includes two first bonding planes 10100 arranged opposite to each other; the first bonding planes 10100 are parallel to the axial direction of the pen tip 101;

[0036] At one end of the pen cap 100 connected to the pen tip 101, at least one second fitting group 1000 is formed on the inner side; the second fitting group 1000 includes two second fitting planes 10000 that are relatively distributed; the second fitting planes 10000 are parallel to the axial direction of the pen cap 100; when the pen tip 101 is removed by relying on the pen cap 100, the first fitting plane 10100 and the second fitting plane 10000 are fitted one by one.

[0037] Compared with the prior art, the pen case 10 provided in this embodiment has a wide and flat contact surface between the pen cap 100 and the pen nozzle 101 when the pen cap 100 is used to disassemble the pen nozzle 101. The force-bearing positions of the pen cap 100 and the pen nozzle 101 are more dispersed and uniform, and will not break. The service life is long, and the pen nozzle 101 can be rotated more conveniently. The holding point or force-applying point on the pen case 10 by the writer or painter can be the end of the pen cap 100 away from the pen nozzle 101 (that is, the end not connected to the pen nozzle 101, or called the more distal end), or the end of the pen cap 100 connected to the pen nozzle 101, or called the more proximal end. When the writer or painter holds the pen case 10 at the more proximal end, the first fitting plane 10100 and the second fitting plane 10000 can be more closely fitted by applying force, so that the pen nozzle 101 can be removed more quickly during the rotation process.

[0038] In some embodiments, Figure 2 and Figure 6 As shown, the outer edge of the pen tip 101 includes a finger contact area 1011 for the end of the finger to contact; with the axial direction of the pen tip 101 as the extension direction, the first contact plane 10100 extends from one side edge of the finger contact area 1011 to the other side edge of the finger contact area 1011. The first contact plane 10100 is set in the finger contact area 1011 and spans the entire finger contact area 1011, so that the first contact plane 10100 can not only provide the function of assisting the removal of the pen tip 101, but also can be used for the end of the finger to contact. Since the first contact plane 10100 is wide and flat, the writer or painter can hold the pen more firmly and not slip easily.

[0039] In some embodiments, Figure 2 and Figure 5 As shown, the pen tip 101 includes a first hollow section 1012, a second hollow section 1013 and a third hollow section 1014 which are sequentially arranged along the axial direction thereof;

[0040] The first hollow section 1012 is the end of the pen tip 101; the third hollow section is the grip section of the pen tip; the first hollow section 1012 and the third hollow section 1014 are both equally wide at both ends; the second hollow section 1013 is not equally wide at both ends, the narrower end is butted and fixed to the end of the first hollow section 1012, and the wider end is butted and fixed to the end of the third hollow section 1014; with the axial direction of the pen tip 101 as the height direction, the ratio of the height of the second hollow section 1013 to the height of the third hollow section 1014 is 0.68-0.78. Under the premise of meeting the grip requirements of the writer or painter, the overall structure of the pen tip 101 is made more compact through the proportion setting, while ensuring that the pen tip 103 has a suitable extension length. Among them, H1 indicates the height of the first hollow section 1012, H2 indicates the height of the second hollow section 1013, and H3 indicates the height of the third hollow section 1014.

[0041] In addition, if Figure 2 and Figure 4 As shown, the pen tip 101 further includes a fourth hollow section 1015 , which is the head end of the pen tip 101 and is threadedly connected to the pen body 102 .

[0042] In some embodiments, Figure 5 As shown, the ratio of the height of the second hollow section 1013 to the height of the first hollow section 1012 is 0.6-0.7. The overall structure of the pen tip 101 is further optimized to make it more compact.

[0043] Compared with the above-mentioned first fitting plane 10100 spanning the entire finger abutment area 1011, in some embodiments, the first fitting plane 10100 may also be located between the finger abutment area 1011 and the pen holder 102, that is, the first fitting plane 10100 is only distributed on one side of the third hollow section 1014, and the extension direction is the axial direction of the pen tip 101, and the extension length of the first fitting plane 10100 is less than 1 / 3 of the length of the third hollow section 1014. This arrangement can separate the first fitting plane 10100 from the finger abutment area 1011, so that there are more choices for the shape of the finger abutment area 1011.

[0044] In some embodiments, Figure 2 and Figure 5 As shown, the second hollow section 1013 is spherical or conical.

[0045] In some embodiments, Figure 6 to Figure 7 As shown, the outer edge of the pen tip 101 is further formed with a first smooth transition surface 1016; two adjacent first fitting planes 10100 are connected by the first smooth transition surface 1016;

[0046] The end of the pen cap 100 connected to the pen tip 101 is also formed with a second smooth transition surface 1001 on the inner side; two adjacent second fitting planes 10000 are connected by the second smooth transition surface 1001. The smooth transition method makes the writer or painter more comfortable to hold and is also more convenient for injection molding.

[0047] In some embodiments, Figure 6 As shown, there are three first fitting groups, which are more in line with the pen-holding habits of general writers or painters. Specifically, for general writers or painters, they will hold the pen with the thumb, index finger and middle finger, and the contact positions of the three fingers and the pen are roughly distributed in an equilateral triangle. There are three first fitting groups, so there are a total of 6 first fitting planes 10100 for writers or painters to choose from.

[0048] In some embodiments, Figure 2As shown, both ends of the pen body 102 are provided with a nib 101; the nib 101 corresponds to the pen cap 100 one by one, so that both ends of the pen body 102 can be disassembled and ink can be added, which has better flexibility.

[0049] In some embodiments, Figure 4 As shown, the inner cavity of the pen body 102 includes a storage cavity 1020 for storing ink; the storage cavity 1020 extends from the middle of the pen body 102 to both sides to supply ink to two nibs 103 respectively inserted into two nibs 101. Compared with setting two storage cavities 1020, only one storage cavity 1020 is set, the structural design is simpler, and the space of the storage cavity 1020 is also larger.

[0050] It should be noted that the pen tip 103 in the present application is not equivalent to the pen tip in CN214523004U, and the specific structure, position and function of the pen tip 103 shall be subject to the description in the present application.

[0051] Based on the above embodiments, the utility model also provides a marker pen 1, such as Figures 1 to 7 As shown, the marker pen 1 includes a pen case 10 described in any one of the above embodiments, and the pen case 10 includes: a pen cap 100, a pen tip 101 and a pen body 102; the pen tip 101 is threadedly connected to the pen body 102; at least one first bonding group is formed on the outer edge of one end of the pen tip 101 connected to the pen body 102; the first bonding group includes two first bonding planes 101000 distributed opposite to each other; the first bonding plane 101000 is parallel to the axial direction of the pen tip 101; at least one second bonding group 1000 is formed on the inner side of one end of the pen cap 100 connected to the pen tip 101; the second bonding group 1000 includes two second bonding planes 10000 distributed opposite to each other; the second bonding plane 10000 is parallel to the axial direction of the pen cap 100; when the pen tip 101 is disassembled by relying on the pen cap 100, the first bonding plane 101000 and the second bonding plane 10000 are bonded one by one. Since the marker pen 1 includes the pen case 10, it has at least the advantages of the pen case 10, that is, when the pen tip 101 is removed by relying on the pen cap 100, the contact surface between the pen cap 100 and the pen tip 101 is wide and flat, the force positions of the pen cap 100 and the pen tip 101 are more dispersed and uniform, and will not break, the service life is long, and the pen tip 101 can be more convenient to rotate. The holding point or force application point on the pen case 10 by the writer or painter can be the end of the pen cap 100 away from the pen tip 101 (that is, the end not connected to the pen tip 101, or called the more distal end), or the end of the pen cap 100 connected to the pen tip 101, or called the more proximal end. When the writer or painter holds it at the more proximal end, the first fitting plane 10100 and the second fitting plane 10000 can be more closely fitted by applying force, so that the pen tip 101 can be removed more quickly during the rotation process.

[0052] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
