Abstract

一种能够直接手握书写的笔芯。它是一种形如卡片、又宽又薄的形状设计。它的宽度可以满足握笔的需要,无须套笔杆即可直接手握书写;它的薄度使它能够象卡片一样插入钱包、书本中,携带十分方便。

Description

卡片形笔芯
本实用新型涉及一种可以直接手握书写的卡片形状的笔芯。
目前的笔芯可以认为由笔尖和其后部的贮油管两部分构成,其中贮油管是细圆管形,其作用只是存贮圆珠笔油。这样,笔芯只有套在笔杆中才能手握写字,由于笔杆往往又粗又长,所以随身携带笔不很方便。
本实用新型的目的在于推出一种新型笔芯,它既能够存贮圆珠笔油,又可以当作笔直接手握书写,而且携带十分方便。
本实用新型的目的是这样实现的:将现有笔芯贮油管的细圆管形设计改为又宽又薄的卡片形设计,利用贮油管的宽度替代笔杆的粗度来增加握笔面积,因此笔芯可以直接手握书写;而薄度不变,可以如卡片一般携带方便。
下面结合附图对本实用新型作进一步详细说明:
图1是卡片笔芯的直观图。
图2是卡片笔芯横截面形状的演变示意图。
图3是卡片笔芯横截面形状的第二个实施例。
由图1可以看出,该笔芯贮油管(1)的宽度要比现有笔芯大的多,且在靠近笔尖(2)的一端,具有圆滑的曲线设计(3),以便于书写。
由图2可以看出,该笔芯贮油管(1)的横截面由细圆环形改为薄度不变、宽度很大的扁椭圆环形,贮油管外壁(4)是圆滑外凸的,(5)是椭圆形的贮油管内壁。
图3中贮油管外壁(4)是圆滑内凹的,内壁(5)形同图2。
与现有笔芯相比,本实用新型具有以下优点:
1,可以直接当作笔手握书写,形如卡片,便于携带,尤其是随身携带。
2,可以夹放留存在书本、文件中,作书签之用,并且翻开书即可得到笔。

Claims (1)

1.一种新型笔芯,保持现有笔芯笔尖、贮油管的两部分组成不变,其特征是:笔芯贮油管的细圆管为又宽又薄的卡片形结构。
