SU14300A1 - Tubular pen for writing patterns - Google Patents

Description

The present invention relates to a tubular pen device for writing on patterns, in which a rubber cap is used to collect ink inside the pen.

In the schematic drawing of FIG. 1 shows a longitudinal section of a feather, and FIG. 2 is a longitudinal section of a rubber cap attached to a feather in the position for air suction.

The said pen consists of a tube 1 (for example, glass, etc.) fitted with a rubber cap with a bottom at the upper end 2 in which a metal rod 3 is fixed on its inner side, in part of its abutment to the outer surface of pen 1, designed, when turned, to form a passage for outside air B pen reservoir.

When using the pen, pre-draw the mascara, act as a pipette, and then, holding the pen so that the standing rubber tube with the rod touches the index finger.

stencilled until the pressure decrease in tube 1 prevents the carcass from flowing out. Then, without changing the position of the hand, press with a thumb on the glass tube so that the rubber cap deviates to the side along with the rod 3, which consequently raises the edge of the cap 2 with its end, thereby inward air. Thereafter, the pen can be operated again until a certain depression of air in the tube 1, when the described operation should be repeated.

The subject of the patent.

A tubular pen for writing in patterns, characterized in that in a rubber cap with a bottom in the upper end, used to collect ink inside the pen, applied from the inside, in the part adjacent to the outer surface of the pen, a metal rod intended to form aisles outside air into the pen tank.
