[0031] See also Figure 1 and Figure 2As shown, in one embodiment of the present invention, a writing instrument 100 is provided. The writing instrument 100 comprises a pen cap 10 and a pen holder 20 which cooperate with each other, and a pen core body 30 which is arranged inside the pen holder 20.

[0032] Specifically, the pen cap 10 includes a pen cap body 11 and a pen cap head 12 detachably connected to one end of the pen cap body 11 .

[0033] Combination Figure 3 As shown, the pen cap body 11 includes a shell 111 and a nib receiving portion 112 built into the shell 111. The shell 111 and the nib receiving portion 112 are arranged at intervals along the radial direction of the pen cap body 11. The shell 111 is fixedly connected to the nib receiving portion 112 via a plurality of ribs 113 arranged on the outer wall 1121 of the nib receiving portion 112. The plurality of ribs 113 are arranged at intervals. For details, please refer to Figures 6 to 8 shown.

[0034] Furthermore, in this embodiment, a plurality of ribs 113 are arranged along the radial direction of the cap body 11. In other words, each rib 113 is perpendicular to the inner wall 1111 of the housing 111. Figure 7 and Figure 8 shown.

[0035] Combined with reference Figure 6 As shown, in this embodiment, a plurality of ribs 113 are arranged at equal intervals along the outer circumference of the nib receiving portion 112. Such a design can enhance the fixed connection between the housing 111 and the nib receiving portion 112.

[0036] Return to Reference Figure 3 , and combined with Figure 8 As shown, the first end 1123 of the nib accommodating portion 112 in this embodiment protrudes from the first end 1113 of the shell 111 close to the cap head 12 along the axial direction of the cap body 11. In other embodiments, the first end 1123 of the nib accommodating portion 112 is flush with the first end 1113 of the shell 111 close to the cap head 12, or, in some embodiments, the first end 1123 of the nib accommodating portion 112 is recessed into the first end 1113 of the shell 111 close to the cap head 12 along the axial direction of the cap body 11.

[0037] In some embodiments of the present invention, the cross-sectional shape of the outer shell 111 of the pen cap 10 is circular, elliptical, or regular hexagonal. Figure 3 As shown, in this embodiment, the cross-sectional shape of the outer shell 111 of the pen cap 10 is a regular hexagon. Fig. 9 and Fig.10 As shown, in this embodiment, the cross-sectional shape of the outer shell 111 of the pen cap 10 is circular.

[0038] Return to Reference Figure 3 , and combined with Figure 4 and Figure 5 As shown, the pen cap head 12 includes a flange portion 121 and a connecting portion 122 connected to the flange portion 121 .

[0039] Specifically, a pattern area is provided at the top of the flange portion 121, and the pattern area is hollow. In other words, the top of the pen cap head 12 has a hollow pattern area (not shown in the reference numeral figure). Figures 3 to 5 As shown, the pattern area is provided with a plurality of regular or irregular hollow holes 1210. In the present embodiment, three hollow holes 1210 are provided in the pattern area, two of which are symmetrically arranged and spaced apart from the remaining hollow hole 1210, and form a "smiley face" pattern. Of course, in other embodiments, the pattern area may also have two, four or more hollow holes 1210. Alternatively, in some embodiments, the plurality of hollow holes 1210 in the pattern area may also form an expression pattern (e.g., an expression of "wide eyes" formed by two larger hollow holes), or a digital pattern (e.g., the number "1" formed by a plurality of hollow holes), but is not limited thereto.

[0040] like Figure 5 As shown, the flange portion 121 and the connecting portion 122 are integrally arranged. The flange portion 121 and the connecting portion 122 are internally connected to form a hollow structure. When the pen cap head 12 is connected to the pen cap body 11, the hollow structure can be used to accommodate the first end 1123 of the pen tip accommodating portion 112.

[0041] like Figure 7 As shown, in this embodiment, the housing 111 clamps the connecting portion 122 . Specifically, the inner wall of the housing 111 abuts against the outer wall 1221 of the connecting portion 122 .

[0042] Furthermore, in this embodiment, the connection portion 122 is plug-connected to the housing 111 , and the housing 111 clamps the connection portion 122 . At this time, the inner wall 1111 of the housing 111 abuts against the outer wall 1221 of the connection portion 122 .

[0043] In some other embodiments, the inner wall 1111 of the shell 111 (and close to the first end 1113 of the shell 111) and the outer wall 1221 of the connecting portion 122 have corresponding / matching threads, and the connecting portion 122 is screwed into the shell 111 via a threaded connection (i.e., the shell 111 is sleeved on the connecting portion 122 and threadedly connected to the connecting portion 122), so that the shell 111 clamps the connecting portion 122, and at this time, the inner wall 1111 of the shell 111 abuts against the outer wall 1221 of the connecting portion 122.

[0044] As described above, the top of the pen cap head 12 (specifically, the top of the flange 121) has a pattern area, which is hollowed out, and there is a gap between the inner wall 1222 of the connecting portion 122 in the pen cap head 12 and the outer wall 1121 of the nib receiving portion 112, forming an air passage. In other words, air can flow through the air passage formed by the hollow holes 1210 (a plurality of hollow holes 1210 form a hollow pattern) of the pen cap head 12, the gap 1224 between the inner wall 1222 of the connecting portion 122 and the outer wall 1121 of the nib receiving portion 112, and the gap 1131 between the plurality of ribs 113, which can prevent users (especially children) from accidentally swallowing the pen cap 10 and causing respiratory obstruction and suffocation.

[0045] It should be noted that, in this embodiment, Figure 7 As shown, when the pen cap head 12 is connected to the pen cap body 11, an end 1223 of the connecting portion 122 in the pen cap head 12 (i.e., the end away from the flange portion 121) is spaced apart from the rib 113 in the pen cap body 11 along the axial direction of the pen cap 10 (i.e., has a spacing), thereby further ensuring the flow of gas in the above-mentioned air channel.

[0046] In this embodiment, the pen cap head 12 (specifically the connecting portion) with a hollow pattern can be inserted and connected to the housing 111 or screwed into the housing 111. Therefore, the pen cap head 12 with a hollow pattern is replaceable, so that the user can replace the pen cap 10 according to his or her needs, thereby achieving different pen cap 10 appearances, thereby achieving personalized and customized effects, and enhancing the user experience. In addition, since the same type of pens can have different pen cap 10 appearances, when a large number of pens described in the utility model are used together, they can be easily distinguished from each other, effectively preventing confusion between multiple pens of the same type.

[0047] Return to Reference Figure 3 As shown, a core body 30 is disposed inside the pen barrel 20, and a core tip 31 extends from one end of the core body 30. Since the nib accommodating portion 112 is a hollow structure, the nib accommodating portion 112 is used to accommodate the core tip 31 when the pen cap 10 and the pen barrel 20 cooperate with each other.

[0048] In addition, the refill body 30 of the utility model can be configured accordingly according to the user's needs. In the embodiment of the utility model, the refill body 30 can be one of a ballpoint pen, a rollerball pen, and a gel pen. Of course, in other embodiments, the refill body 30 can also be other types of refills.

[0049] The embodiment of the utility model provides a writing instrument 100, wherein the pen cap head 12 of the writing instrument 100 is designed as a hollow pattern, and there is a gap between the inner wall 1222 of the connecting portion 122 of the pen cap head 12 and the outer wall 1121 of the pen tip receiving portion 112 in the pen cap body 11, forming an air passage to prevent the user from accidentally swallowing the pen cap 10 and causing respiratory obstruction and suffocation. In addition, the pen cap head 12 with a hollow pattern of the utility model is replaceable, so that different pen cap 10 appearances can be obtained, the product is personalized, and the user experience is enhanced, and confusion between multiple writing instruments of the same type can be effectively prevented.
