The soft cover of the pen holder in China is not specific to the cover body. The width of the above-mentioned various kinds of holding parts is considered to have a segment difference. In addition, the plasticity and the sense of coldness and warmth, and the problem of the original purpose of the creation. The specific surface is tightly sleeved with a holding part to the back of the pen. The foam tree holding part or the front cone is used to position the patent. The structure of the patent publication is improved. The cover with the same color is still a conventional ring with a wide ring size. Or an elastic material that fits well] In a word, the long tubular end extends to the outer periphery of the fat foam to form a uniform pen. And the waves of rules are not simply rules. The elastic grip cover is formed with a receiving portion formed on both ends or ends, thereby forming a "three-dimensional heterochromatic embossment" No. 48451 8 to reveal a embossment formed on the surface of the cover The pattern to increase the visibility of the pen or to fit inside the annular groove of the grip. The sexual grip or cover must be positioned in the grip groove of the pen holder, so the outer diameter of the pen must be provided with a portion to form a ring groove and become a more structured cover. The cover uses synthetic rubber, silicone rubber, and heat (elastomer). ), It is not very sticky and soft when holding. A writing tool capable of improving the creation of the above-mentioned conventional writing tool. A writing tool is provided. The outer periphery of the pen shaft is soft and flexible, and the grip from the rear of the front cone is less than half of the length of the pen shaft. The cotton tube is directly covered on the outer diameter. The cover is a continuous tube with a continuous pattern on the outer surface, but it can also be formed without ripples.

Page 5 M254353 V. Creation Instructions (3) The length is very long, not only the fingers held by the fingers, but also the tiger's mouth between the thumb and forefinger.

It is attached to the cover, and there is no sticky feeling or cold feeling, so the grip is very good. I The writing instruments referred to in this creation not only refer to writing instruments such as ballpoint pens, mechanical pencils, pens, markers, highlighters, etc .; they also refer to cosmetic pens such as eyebrow pencils, makeup check pens, and pen lipsticks; , Also includes various pen-type tools such as correction pen, rubber ^ wipe pen, engraving knife, etc., described here. [Embodiment] The following is a detailed description of the embodiment of this creation according to the drawings: Figure 1 The first diagram is a partial cross-section of the first embodiment of the writing pen, and the second diagram is the diagram after removing the internal refill mechanism Sectional view of the writing implement of the first figure along line I-I. The writing tool with this creation has a tubular pen holder 1 with a front cone 11 connected to the front end and a pressing head 12 that can be pressed to retract the pen core. The pen cup 1 is basically an outer diameter of equal diameter. The body of the tube is tightly sleeved with a shell [raw soft shell cover 2], which is held from the front of the pen 1, that is, the rear part of the front cone 1 1 extends to the rear end of the pen 1 to almost the entire length of the pen 1 . The cover 2 is made of foamed tubular body made of foamed resin such as EVA (ethylene-vinyl acetate resin). Its inner diameter is equal to or slightly smaller than the outer diameter of the pen. The continuous undulating corrugated surface 21 forms a continuous pattern π. The sleeve 2 can be formed by foaming directly on the outer periphery of the pen holder 1 or can be tightly sleeved on the pen holder 1 by its own elastic expansion. In this ΓίΠ core t tool: two are applicable, ballpoint pen is taken as an example, so the content of the pen 1 ′, “a 疋, as mentioned, this pen tool can also be automatic lead

Page 6 M254353 V. Creative Instructions (4) Pen, signature pen, drawing pen, etc. The third figure shows partial cross-sectional views of various modifications of the cover 2 of the above embodiment. A continuous corrugated surface 2 1 is formed on the outer peripheral surface of the cover 2 of the previous embodiment with a regular and large pitch (ie, thinner). , But the figure (A) shows a regular continuous corrugated surface 2 1 a with a small pitch (ie, denser). Figure (B) shows two continuous corrugated surfaces 2 1 b, 2 1 b ′ formed on the outer peripheral surface of the cover 2 with two different pitches. Figure (C) shows that the cover 2 has continuous corrugated surfaces 2 1 c, 2 1 c ′ having different heights and pitches. Figure (D) shows a surface 2 1 d with a part that is a corrugated surface 2 1 1 and a part that is not corrugated, that is, a flat surface 2 1 2. Figure (E) shows the surface 2 1 e of many small protrusions 2 1 3 with a uniform distribution. Figure (F) shows that only a flat surface 2 1 f is formed. Further, in the foregoing embodiment, the inner diameter d of the cover 2 is formed as a uniform diameter that is continuous from one end to the other end, but the figure (G) shows that the inner diameter d of the cover 2 is a discontinuous diameter. In this writing tool, the cross section of the pen 1 and the matching cover 2 is generally circular (second picture), but the shape of the cross section is not limited to this. In fact, the cross section of the pen 1 can be covered with the cross section. The sleeve 2 forms a corresponding sectional shape. The fourth figure is a sectional view showing the non-circular cross section of the pen holder 1 and the cover 2. Figure (A) shows that both the pen holder 1 and the cover 2 form a triangle; Figure (B) shows a quadrangular shape; Figure (C) shows a hexagonal shape; Figure (D) shows an oval shape. However, the outer section of the cover 2 does not have to be the same as the section of the pen holder 1. Figure (E) indicates that the section of the pen holder 1 is triangular, and the cross section of the cover member is circular, but has a section that matches the pen holder 1 The inner diameter of the shape (that is, the triangular hole); Figure (F) shows that a set of quadrangular pens is covered with a circle. There are still many other changes in shape, depending on design needs.

M254353 V. Creation instructions (5) The length of the cover 2 is designed to allow everyone to easily and comfortably hold their pens and the size of their palms, and to protect the pen from damage when dropped, it must have at least one pen 1 More than half of the length is preferably a length of almost full length extending from the grip to the rear end of the pen holder 1. A cover of this length is not only a writing grip, but actually constitutes the entire pen. The protective cover is made of foam material and has more soft and elastic deformation effects. This is an unprecedented structure and effect of the conventional grip sleeve. V. [Creation effect] This writing pen with a long cover made of foamed resin (foam) has good elasticity and softness of the cover and a larger deformation rate. Therefore, it has good performance when held and used. The touch and fit are not as sticky as the synthetic rubber cover, so the grip is very good. Long-term writing can reduce the fatigue of the fingers. At the same time, because the cover is long and cushioning, It protects the pen shaft and reduces the risk of being dropped when dropped.
