Description
TECHNICAL AREA
[0001] The utility model belongs to the technical field of improvements to pens and relates in particular to a pen with a pen sleeve that protects against loss, in which the sleeve cannot be separated from the pen body. STATE OF THE ART
[0002] Traditional pens generally consist of a barrel and a cap. At the front end of the barrel is a writing nib. The cap is placed on the barrel and encloses the nib to protect it when not in use. When needed, the cap is removed, allowing the nib to write, which is relatively simple. However, a common problem is that the cap is easily lost, leaving the pen unsightly and the nib unprotected when not in use. Furthermore, the ink dries out easily if the nib is left unprotected for extended periods, rendering the pen unusable.
[0003] For this reason, we have developed a pen where the protective sleeve cannot be separated from the pen body and is therefore protected from loss. CONTENT OF THE PRESENT INVENTION
[0004] The aim of this utility model application is to provide a pen with a pen sleeve that protects against loss and in which the pen sleeve cannot be separated from the pen body.
[0005] To achieve the aforementioned objective, the utility model offers the following technical solution: A pen with a protective casing to prevent loss, consisting of a pen body and a pen cap, wherein a writing tip is arranged at the head of the pen body for writing; wherein the pen cap is placed on the pen body and cannot be removed; wherein, when in use, the writing tip protrudes from the pen cap; and wherein, when not in use, the writing tip is concealed in the pen cap.
[0006] Preferably the pin body is provided with an external thread, while the pin cap has an internal thread; the internal thread and the external thread interlock, allowing the pin cap to be moved along the pin body.
[0007] Preferably, a tip opening is provided at the top of the pen cap so that the writing tip can protrude from the pen cap and be used for writing.
[0008] Preferably, the pen cap serves as a handle when the writing tip is used for writing.
[0009] Preferably, a retaining clip is provided on the side of the pen cap; there is at least a partial gap between the retaining clip and the pen cap to facilitate hanging.
[0010] In comparison to the prior art, the present utility model application offers a pen with a pen casing that protects against loss and has the following advantageous effects: The pen described in the present utility model application, with a pen casing designed to prevent loss, comprises a pen body and a pen cap; a writing tip is arranged at the front end of the pen body for writing purposes; the pen cap is attached to the pen body and is not removable; when in use, the writing tip can protrude from the pen cap; when not in use, the writing tip can be stored in the pen cap; since the pen cap cannot be separated from the pen body, there is no risk of the pen cap being lost with this utility model; moreover, it is very easy to use.

[0013] The technical solution of the embodiment of the present utility model application is described clearly and completely below with reference to the accompanying figures. It is understood that the described embodiments represent only a portion of the embodiments of the present utility model application and do not encompass all embodiments; all further embodiments that a person skilled in the art in this field arrives at based on the embodiments of the present utility model application without any inventive effort fall within the scope of protection of the present utility model application.
[0014] Please note the Fig. 1, Fig. 2, Fig. 3 to Fig.4. The present utility model application presents a technical solution: a pen with a pen casing to protect against loss, consisting of a pen body 1 and a pen cap 3, wherein a writing tip 2 is attached to the front end of the pen body 1 for writing; the pen cap 3 is placed on the pen body 1 and is not removable; when in use, the writing tip 2 protrudes from the pen cap 3; when not in use, the writing tip 2 is concealed in the pen cap 3.
[0015] In this embodiment, the pin body 1 is provided with an external thread 11, while the pin cap 3 has an internal thread (not shown); the interaction of the internal and external threads makes it possible to move the pin cap 3 along the pin body 1.
[0016] In this embodiment, a tip opening 31 is provided on the top of the pen cap 3 so that the writing tip 2 can protrude from the pen cap 3 and be used for writing.
[0017] In this embodiment, the writing tip 3 serves as a grip area when the writing tip 2 is used for writing.
[0018] In this embodiment, a retaining clip 32 is provided on the side of the said pin cap 3; there is at least a partial gap between the said retaining clip 32 and the pin cap 3 to facilitate hanging.
[0019] In use, the pen cap 3 is slid along the pen body 1, causing the writing tip 2 to protrude from the tip opening 31 of the pen cap; by holding the pen cap 3 in the hand, it can be used for writing; when not in use, the pen cap 3 is also slid along the pen body 1, concealing the writing tip 2 inside the pen cap 3, thus protecting the writing tip; at the same time, the pen cap 3 cannot be lost, as it is not separated from the pen body 1.
[0020] Compared to the prior art, the present utility model application has the following advantages: The pen described in the present utility model application, with a pen casing designed to prevent loss, comprises a pen body 1 and a pen cap 3, wherein a writing tip 2 is arranged at the head of the pen body 1, which serves for writing; the pen cap 3 is attached to the pen body 1 and cannot be separated from it; when in use, the writing tip 2 can protrude from the pen cap 3; when not in use, the writing tip 2 can be concealed in the pen cap 3; since the pen cap 3 cannot be separated from the pen body 1, the pen cap 3 is not lost in this utility model; moreover, it is very easy to use.
[0021] Although embodiments of the present utility model have been presented and described, it is understandable to a person skilled in the art that numerous changes, modifications, substitutions, and variants can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is limited by the appended claims and their equivalents.
