Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," "upper," "lower," "front," "rear," and the like as used herein, are for purposes of description only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, 2 and 3, a perspective pen cap comprises an inner sleeve 20, wherein the inner sleeve 20 is a cylindrical hollow structure with one closed end and the other open end;

the closed end of the inner sleeve 20 is provided with a fixed head 10, the open end of the inner sleeve 20 is provided with an outer shell 30 which can completely cover the outer side of the inner sleeve 20, the outer shell 30 is a cylindrical hollow structure body with two open ends, the inner side of the outer shell 30 is sleeved with the outer side of the inner sleeve 20 in a clearance fit manner, and the outer shell 30 can slide along the axis of the inner sleeve 20 to be far away from or close to the fixed head 10;

the inner sleeve 20 is a transparent material.

As shown in fig. 3, when the outer case 30 is far from the fixing head 10, a gap formed between the outer case 30 and the fixing head 10 allows a user to view the inside of the inner case 20 through the transparent inner case 20;

as shown in fig. 2, when the outer case 30 is brought close to and in contact with the fixing head 10, the outer case 30 and the fixing head 10 entirely cover the surfaces except the closed end of the inner case 20, preventing light from being transmitted therethrough.

With this design, when the end of the pen point 71 of the pen holder 70 is inserted into the cap, the user pulls the housing 30 away from the fixing head 10, and the user can observe the shape and size of the pen point 71 through the transparent inner sleeve 20, thereby preventing the cap from being inserted and removed.

After the observation is finished, the outer shell 30 is shifted to be close to the fixed head 10, the outer shell 30 is made to cover the inner sleeve 20, the ink property change on a pen point caused by light is avoided, and the function is particularly practical for some light-sensitive inks or painting and calligraphy mark pens which are created and written from nature under outdoor strong light.

Further, one end of the fixing head 10 away from the shell 30 is provided with a color code 50; when the pen cap is sleeved in the pen holder 70, the painting and calligraphy colors of the pen cannot be accurately judged, and the color code 50 is used for indicating the painting and calligraphy colors of the pen, so that a user can intuitively judge the painting and calligraphy colors of the pen without pulling the pen cap, moving the shell 30 and actually painting and calligraphy.

Further, a pen clip 60 is arranged on the fixing head 10; the clip 60 is used to secure a cap or implement to another object.

Further, a snap ring 21 is disposed on the inner side of the inner sleeve 20, and the snap ring 21 is a ring-shaped structure protruding or recessed from the inner surface of the inner sleeve 20. The pen holder 70 is provided with a protrusion or recess structure which is engaged with the snap ring 21, so that the pen holder 70 is engaged with the cap, and the pen holder 70 and the cap are not separated from each other when no external force is applied.

Furthermore, the case 30 and the fixing head 10 are respectively provided with a detent 22 at a side close to each other, and the detent 22 is an annular structure protruding from the surface of the case 30 and the fixing head 10. When the user forcibly engages the housing 30 with the fixing head 10 through the engaging position 22, the housing 30 and the fixing head 10 are not separated when no external force is applied.

Further, a spring 40 is disposed between the inner sleeve 20 and the outer shell 30, and the spring 40 enables the outer shell 30 to approach the fixing head 10 in a state of not being subjected to an external force.

Further, the material of the inner sleeve 20 is one of PP, PE or PC.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the present invention.
