Detailed Description

As shown in fig. 1 to 3, the casing structure of the eyeliner container of the present invention comprises a pen body 100, a connecting seat 500, a pen point 700, an inner cap 800 and a pen cap 900.

The pen body 100 is a circular tube, one end of the pen body is a closed end, the other end of the pen body is an open end, and a circle of assembling grooves 131 are formed in the position, close to the open end, of the inner tube wall of the pen body 100.

The connecting base 500 is also hollow and tubular, and has a circle of convex ring 501 protruding from the outer circumference on the outer circumference, the convex ring 501 divides the connecting base 500 into a pen body matching section 502 located on one side of the convex ring 501 and a pen cap matching section 503 located on the other side of the convex ring 501. A ring of raised mounting ribs 504 are provided on the body engaging section 502 near the collar 501. After the connecting seat 500 is assembled with the pen body 100, the assembling ridge 504 is located in the assembling groove 131 in a tight fit manner, and the opening end surface of the pen body 100 is stopped and positioned by the convex ring 501. After assembly, the connecting seat 500 does not fall off the pen body 100, and cannot rotate relative to the pen body 100.

The nib 700 is composed of a thin rod 710 at the front end and a thick rod 720 at the rear end which are integrally connected, and has a through hole 740 therein, the through hole 740 being filled with a gel-like pen core, and having a core outlet 741 at the front end. The tip of wand 710 has a tapered sealing surface. The combination of the thin shaft 710 and the thick shaft 720 has a positioning flange 721 protruding the circumference of the thick shaft 720. The connecting seat 500 is sleeved on the thick rod 720 in a tight fit manner and is stopped and positioned by the positioning flange 721.

Specifically, the outer surface of the thick rod 720 also has a ring of raised mating ribs 722, and the wall of the through hole of the connector holder 500 also has a mating groove 506 therein. The engaging rib 722 of the thick rod 720 is loosely fitted in the engaging groove 506 of the connecting socket 500, and a gap is provided between the thick rod 720 and the inner wall of the through hole 740, so that the pen tip 700 cannot fall off from the connecting socket 500, but can rotate relative to the connecting socket 500.

Referring to fig. 4, the inner cap 800 is open at one end and closed at the other end, and is composed of a cap body 810 and a cap seat 820 at the bottom of the cap body 810, wherein the cap seat 620 has a circumferential annular groove 821 on the outer circumference and a symmetrical vertical groove 822 on both sides. The cap 810 is tapered, and has a large outer diameter at the mouth and a small outer diameter at the joint with the cap base. The inner wall of the inner cavity of the inner cap 800 is a conical sealing surface. Such a configuration allows the cap seat to be easily elastically deformed and pressed into the cap when the inner cap 800 is fitted into the cap.

As further shown in fig. 1, the cap 900 is also cylindrical, with one end being a closed end and the other end being an open end. The cap 900 is divided into a bottom section 910, a main section 920 and a fastening section 930 in sequence from the closed end to the open end. As shown in fig. 3, the bottom section 910 has a protruding ring 911 near the bottom and a reverse tapered clamping surface 912 at the top. After the inner cap 800 is assembled to the bottom section 910, the protruding ring 911 of the bottom section 910 is clamped in the annular groove 621, and the reverse tapered clamping surface 912 is pressed on the top edge of the inner cap 800, so that the inner cap 800 cannot fall off from the pen cap 900, and is fixed stably without looseness. The inner wall of the snap section 930 also has an annular protrusion 931. Correspondingly, a circle of concave fitting grooves 505 are formed on the outer circumferential surface of the cap fitting section 503 of the coupling holder 500. After the pen cap 900 is fastened in place, the annular protrusion 931 falls into the matching groove 505, so that the pen cap 900 is not easy to fall off, and a user has good fastening and pulling experience when fastening.

However, those skilled in the art should realize that the above embodiments are only used for illustrating the present invention and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are all within the scope of the appended claims as long as they are within the true spirit of the present invention.
