Abstract

The utility model discloses a pen cap in common use. The pen cap comprises a pen head sleeve made of rubber and a pen holder sleeve made of rubber. The pen head sleeve is in the shape of a hollow cone; the bottom surface a of the pen head sleeve is not enclosed; a rubber pad is disposed in the pen head sleeve and near the tip of the pen head sleeve; the side, which is far away from the tip of the pen head sleeve, of the bottom surface a is provided with the pen holder sleeve; the pen holder sleeve is in the shape of a hollow circular truncated cone and is internally communicated with the inside of the pen head sleeve; the side, which is far away from the bottom surface a, of the pen holder sleeve is bottom surface b; and the bottom surface b is not enclosed. The pen cap in common use can be sleeved on pens of different specifications, so that the problem that pens are wasted because the conventional pen caps cannon be used universally is solved and the service lifetime of the pens is prolonged.

Description

A kind of general cap for brush

Technical field

The utility model belongs to the office appliance field, relates to a kind of general cap for brush.

Background technology

Pen is one of modal instrument in our daily life, and the cap for brush is self-existent as the device of protection pen, thus lose easily in daily life, and make nib can not get protection, cause the inconvenience in the life.The existing cap for brush on the market can only man-to-man supporting use, pen that can not general various different sizes, and in a single day the cap for brush is lost, and this use will be very inconvenient, and regular meeting is abandoned by the people, thereby causes waste.

Summary of the invention

The purpose of this utility model provides a kind of general cap for brush, and having solved the existing cap for brush can not be general, makes the wasting problem of pen easily.

The technical scheme that the utility model adopts is, the general cap for brush, comprise the pen point casing of rubber material and the Pen-holder sleeve of rubber material, pen point casing is that the hollow cone bodily form and its bottom surface a do not seal, the inside of pen point casing is provided with rubber blanket near its summit, and bottom surface a is provided with Pen-holder sleeve away from a side on pen point casing summit, and Pen-holder sleeve is hollow truncated cone-shaped and connects with the inside of pen point casing, Pen-holder sleeve is bottom surface b away from the side of bottom surface a, and bottom surface b does not seal.

Characteristics of the present utility model also are,

The diameter of bottom surface b is not more than the diameter of bottom surface a.

The beneficial effects of the utility model are, by the setting of the general cap for brush, a kind of cap for brush can be enclosed within on the pen of multiple different size, and having solved the existing cap for brush can not be general, makes the wasting problem of pen easily, has prolonged the service life of pen.

Description of drawings

Fig. 1 is the structural representation of the general cap for brush of the utility model.

Among the figure, 1. rubber blanket, 2. bottom surface a, 3. bottom surface b, 4. Pen-holder sleeve, 5. pen point casing.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

The utility model provides a kind of general cap for brush, referring to Fig. 1, comprise the pen point casing 5 of rubber material and the Pen-holder sleeve 4 of rubber material, pen point casing 5 does not seal for the hollow cone bodily form and its bottom surface a2, the inside of pen point casing 5 is provided with rubber blanket 1 near its summit, and bottom surface a2 is provided with Pen-holder sleeve 4 away from a side on pen point casing 5 summits, and Pen-holder sleeve 4 connects for hollow truncated cone-shaped and with the inside of pen point casing 5, Pen-holder sleeve 4 is bottom surface b3 away from the side of bottom surface a2, and bottom surface b3 does not seal.

When using, draw back the bottom surface b3 of Pen-holder sleeve 4, nib is inserted the general cap for brush from bottom surface b3; make nib arrive to the position of rubber blanket 1, Pen-holder sleeve 4 is enclosed within on the penholder, so; in pen point casing 5 just is wrapped in whole conical nib, played the effect of protection nib.

The diameter of bottom surface b3 is not more than the diameter of bottom surface a2, can increase the frictional force of Pen-holder sleeve 4 and penholder, and Pen-holder sleeve 4 better is enclosed within on the penholder, effectively prevents coming off of the general cap for brush.

Because the retractility of rubber, make the size of Pen-holder sleeve, pen point casing can adapt to the pen of various sizes, solving the existing cap for brush can not be general, makes a wasting problem easily.
