Problems solved by technology

[0002] There are two designs of common gel pens in the market: one of them is used with a cap and a pen holder, and the cap is separated from the pen holder during the writing process. Can be discarded, resulting in a waste of resources; the other does not require a cap, but is equipped with springs, knobs and other mechanisms in the barrel, which is more complicated to disassemble and not suitable for standard gel refills

Embodiment Construction

[0017] in such as Figure 1-5 In the example shown.

[0018] figure 1 For the assembly front view of the present invention in the writable state, insert the universal neutral pen core 13 into the tail plug 1, the tail plug 1 and the pen holder 2 are assembled together by the external thread 6 and the internal thread 9, and the external thread of the tail plug 1 6. During the process of screwing into the internal thread 9 of the pen holder 2, the universal neutral pen core 13 is clamped and fixed on the tail plug 1 by the cooperation of the rubber gasket 4, the anti-skid protrusion 5, and the longitudinal slot 7 in the tail plug 1. Now the spring-type nib 8 is compressed so that the plug 11 is inserted into the draw-in groove 10 and fixed and then the assembly of the present invention is completed. When the spring-type nib 8 is in the compressed and fixed state, the nib leaks out to complete the normal writing work. After the writing is finished, unplug the spring Type nib 8,...

Abstract

The invention discloses a pen-holder design of a gel pen without a pen cap. The pen-holder design is composed of a tail plug and a pen holder, and is not provided with other detachable parts, whereina pen core is arranged behind and is fixedly arranged on the tail plug; the front end of the pen holder is integrally designed into a spring-shaped telescopic structure which is named as a spring typepen head; under a conventional state, the pen-holder design is in an extension state; after being compressed, the pen-holder design is connected and fixed by an insertion head and a blocking slot, sothat the pen tip of the pen core exposes the pen holder for use; and after the pen is used, the spring type pen head is unplugged, so that the spring type pen head at the front end of the pen holderreturns to the extension state, and the length of the pen holder is increased, and therefore, the pen tip of the pen core is folded into the pen holder to accomplish storage.

Description

technical field [0001] The invention relates to writing or drawing utensils, in particular to a gel pen holder which does not need a cap and is suitable for standard gel pen cores. Background technique [0002] There are two designs of common gel pens in the market: one of them is used with a cap and a pen holder, and the cap is separated from the pen holder during the writing process. Can be discarded, resulting in a waste of resources; the other does not require a cap, but is equipped with springs, knobs and other mechanisms in the barrel, which is more complicated to disassemble and not suitable for standard gel refills. Contents of the invention [0003] The present invention provides a gel pen barrel design with a discarded pen cap. The overall design concept is that the pen core is fixed behind the tail plug, and the pen shell at the front section of the pen barrel is designed as a spiral spring-shaped retractable pen shell in the original state of elongation. The s...
