Abstract
The present invention relates to a plastic writing pencil. Plastics is substituted for wood to produce pencil, and reducing wood consumption. Its production process is simple, it can once extruded. Its pencil holder and pencil core are made integrally. Said pencil is non-toxic, can be arbitrarily cut, and the surface of pencil can be made into the concave-convex form, so that it is favourable for holding and writing.
Description
The present invention relates to a kind of material replaces.Be in particular and substitute timber production with plastics and write and use pencil.
At present, pencil is all done the manufacturing of penholder material with timber.Instrument will not consume a large amount of timber, and to the quality requirement of timber than higher.The annual need cut down a large amount of trees, directly influences environmental protection.
The objective of the invention is: substitute timber with plastics and produce pencil, reduce the consumption of timber.
Plastic pencil of the present invention is to use non-toxic plastic, by plastic extruder, with a penholder and an extrusion molding of pen core.Penholder and pen core are an integral body.Can cut arbitrarily.
Plastic pencil of the present invention can not only be saved timber, and production technology is simple, and easily manufactured, cost is low, and is pollution-free.Also can overcome Wood pencil and differ because of wooden degree of tightness, easily broken lead is usurped phenomenons such as lead during cutting.Plastic pencil both can be made into circle, polygon, the pencil surface can be made again concavo-convexly anti-skiddingly just to hold shape, and have Wood pencil equally and easily cut the function of being convenient to write.
Further specify below in conjunction with drawings and Examples:
Fig. 1 is the vertical section schematic diagram of plastic pencil of the present invention.
＜1〉be plastic penholder,＜2〉be pen core.Penholder and pen core closely are connected to an integral body.
Embodiment:
With reference to accompanying drawing 2, plastics are from extruder barrel＜1〉in press to head＜3, from head＜3〉flow to mould＜4, lead for retractable pencil device＜2〉send the pen core that makes to mould＜4 simultaneously, plastics and pen core are extruded in mould simultaneously, promptly produce plastic pencil＜5 〉.
Claims (3)
1, plastic pencil, penholder substitutes the timber manufacturing with plastics.It is characterized in that penholder and pen core closely are linked to be integral body, can cut arbitrarily.
2, it is characterized in that according to the described plastic pencil of claim 1: this profile can be made into circle and polygon, can also make the concavo-convex anti-skidding shape of just holding on the surface.
3, with reference to the accompanying drawings＜2 〉, this plastics that are fabricated to are extruded once-forming.(comprising penholder and pen core)
