Abstract
A pencil (or eyebrow pencil) as an improvement on existing one is composed of lead and protecting sleeve made up of plastics by integral injection, and features that it is easily sharpened and its lead is not broken easily. Its advantages include easy manufacture and saving wood resource.
Description
The invention belongs to improvement, be meant the pen of easy planing and continuous core especially existing pencil, eyebrow pencil etc.
Existing pencil, eyebrow pencil etc. are formed by pen core and wooden pen core sheath, because its pen core sheath adopts wood materials to make, thereby: 1. wood materials and pen core can not form bond state, very easily disconnected core during planing, and the planing of wood materials is also difficult; 2. the wood materials processing technology is loaded down with trivial details, manufacturing cost is high; 3. need the timber resources of consume valuable when making, and can not reclaim, so bigger to the waste of ecological ideas resource.
The objective of the invention is under the prerequisite of profile that does not change existing pencil, eyebrow pencil etc. and using method; it is improved; particularly the material of its pen core sheath is changed, in the hope of reaching easy planing, the purpose of continuous core, reduction manufacturing cost and protection green resource.
Technical scheme of the present invention is: a kind of pen of easy-to-sharpen and breaking-proof lead, have pen core and pen core sheath, and its pen core sheath adopts the plastics integrated injection molding.
Therefore product of the present invention can make different shape and color owing to adopt the plastics integrated injection molding, and its manufacturing process is the conventional plastic process for manufacturing product, is about to ready made pen core and is held in the plastics mould, gets final product toward in-mould injection, the demoulding then.For reducing manufacturing cost.The present invention can adopt the waste or used plastics manufacturing of recovery.
Through experiment, confirm product of the present invention because pen core sheath and pen core form an integral body, thereby the true easy outstanding advantage of easily broken core not in planing and the planing process of tool, and cheap for manufacturing cost, manufacturing process is simple, process velocity is fast, and can save a large amount of timber resources.
Claims (1)
- A kind of pen of easy-to-sharpen and breaking-proof lead has pen core and pen core sheath, it is characterized in that: described pen core sheath is adopted by the plastics integrated injection molding.
