Description

Stylographic anti-dry brush stylus cap

Technical field:

The invention belongs to the writing implement field, specifically be meant stylographic anti-dry brush stylus cap.

Background technology:

Fountain pen is main writing implement, portable because of it, advantage such as write smoothly is very popular, the phenomenon of water usually can not take place because of nib water evaporates dry brush point in the time spent again but this pen is in a period of time of stopping using, cause many inconvenience, trace it to its cause mainly is that this pen nib periphery after the cap for brush is set on the penholder has bigger space, air in this space can ceaselessly be robbed moisture few on the nib, nib is become dry gradually, simultaneously the fit of the cap for brush and penholder also can make air inside and outside the cap for brush flow mutually inadequately to quicken to take away more moisture finally to cause nib to be killed no longer descend water because of airtight, and this phenomenon needs elimination.

Summary of the invention:

The object of the invention is the new technical scheme that a kind of cap for brush is provided, and it can address the above problem effectively.

The technical program thes contents are as follows: it comprises the cap for brush, and the inherent top of the described cap for brush is connected with the downward colloid pen cap that contains a plurality of pores on cylindric and the cylinder the upper half barrel that is.

The beneficial effect of the technical program be pen cap can cap for brush cover be incorporated on the penholder back tight wrap nib, stoped the air evaporation of nib moisture effectively to peripheral space, make that nib the phenomenon of water can not occur any more when writing once more.

Description of drawings:

The pen cap that Fig. 1 gives an example for the design.

The cap for brush behind the pen cap installation in position that Fig. 2 gives an example for the design.

The effect view of the pen cap that Fig. 3 gives an example for the design.Among each figure, 1 is pore, and 2 is pen cap, and 3 is the cap for brush, and 4 is nib, and 5 is penholder.

The specific embodiment:

Select a kind of more ageing-resistant low durometer stock die forming such as Fig. 1 shape to become pen cap 2, preferably select silica gel for use, be shaped as the approximate tubular that the end is arranged, elastic restoring force should be higher, on the barrel of last 1/2 part, process a plurality of pores 1, pen cap 2 is fixed in the top inside of the cap for brush 3 by adhesive or friction tight form, as shown in Figure 2, the diameter of pen cap should be slightly less than cap for brush internal diameter, the height should the cap for brush high inside about about 2/3, during use after the cap for brush 3 cover is incorporated on the penholder 5, nib 4 can pack in the hollow of pen cap 2, the lower surface of pen cap and part by under barrel receive in can be under the contacting of being inserted in nib tin in the space of hollow, and the nib part is tightened the parcel effect because of the formation of the material characteristic nature of self, air in the tube can or not influence heading into of nib by pore 1 discharge under the effect of being stressed, whole nib part then can be in the state of being lived by minimum space environmental sealing, do not have inside and outside the flowing of air again and take away moisture, can prevent effectively that nib from becoming dry, and reaches and be in the state of fluently writing to be written constantly.The form of pen cap 2 also can have other selection, such as to lower open mouth shape etc., because the concrete shape of nib has big nib, little nib, also has needle tubing shape nib, the pen cap of other form adapts to the difform ability of nib and all owes desirable, and the bottomless drum shape pen cap that has of originally giving an example then all has the anti-effect of doing of comparatively ideal sealing to various Fountain pen nibs.

Claims (1)

1. stylographic anti-dry brush stylus cap, it comprises the cap for brush, it is characterized in that the inherent top of the cap for brush is connected with the downward colloid pen cap that contains a plurality of pores on cylindric and the cylinder the upper half barrel that is.
