Abstract
The utility model aims to provide a pen cap, the technical proposal of which is that the pen cap is a tubular structure with two ports, wherein, the middle part of the tubular structure is sealed by two symmetrical cone structures which are made of elastic rubber materials. The utility model has the advantages of simple structure, convenient manufacture and suitability for popularization.
Description
Technical field
The utility model relates to a kind of pen cap.
Background technology
Everyone has several pencils the student who goes to school, and has used weak point when pencil, and the inconvenience of writing has just been thrown away.Because pencil is made with trees, do so very and waste resource, use all right again if can manage a short pencil.
If utilize a kind of pen cap, be enclosed within on the short pencil, with the short pencil spreading, just can continue to have used, also reached the purpose that economizes on resources with environmental protection.
The utility model content
The purpose of this utility model is for a kind of pen cap of energy-conserving and environment-protective is provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of pen cap, it is characterized in that the described pen cap is a tubular structure with two ports, and the middle part of tubular structure is sealed by the conical structure of two symmetries.
Described conical structure is flexible elastomeric material.
Advantage of the present utility model is that simple in structure, easily manufactured, popularization suits.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For the utility model is further described, illustrated below in conjunction with specific embodiment.
As shown in Figure 1, the described pen cap is a tubular structure with two ports 2,3, and the middle part of tubular structure is by conical structure 1 sealing of two symmetries.
Preferably, conical structure 1 is flexible elastomeric material.
Environment-protective pencil sheath of the present utility model is longer than the general pen cap, and shorter pencil is held in the hand also and can uses after injecting; A short pencil (can different colours) is all injected at two ends, turns back and just can write again.
And, have elasticity because the hermetically-sealed construction 1 of position, intermediate portion is the elastomeric material making, therefore can more closely fix pencil jointly, and can not produce the phenomenon of rocking with the tube wall of the pen cap.
The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
