SU1216028A1 - Fountain pen - Google Patents

Description

The invention relates to writing instruments.

The purpose of the invention is to improve the technological design.

The drawing shows a fountain pen, a general view.

The pen has a tubular body 1, a replaceable reservoir 2 for a dye with a writing unit 3, a stopper 4 made of an elastic material, for example of rubber,; And cap 5 / with pocket holder 6.

At the same time, the stopper 4 is fixed at the end of the tubular body 1 with a seating surface and holds the replaceable reservoir 2 for the dye. In addition, in the stopper 4 there is a central channel 7 for ensuring the passage of air into the dye reservoir 2. The cap 5 is mounted on the cap 4 with a tension, forming the chamber A for applying pressure to the dye, and is telescopically connected with the outer surface of the tubular body 1. The shape of the inner surface of the cap 5 is cylindrical, and

the outer surface of the tube 4 is rounded under the oval to reduce the friction surface. The tubular body 1, at the end of the arrangement of the writing unit 3, has a portion 8 of the outer polyhedral surface below

cap 5.

The use of a fountain pen involves the application of pressure to the volume of the dye in the tank 2 to ensure its movement to the writing unit 3, for

which the cap 5 telescopically moves along the outer surface of the tubular body 1. In this case, the pressure in the hermetic chamber A increases and, due to the presence of a message through the central channel 7 of the plug 4, affects the volume

dye, moving it to the writing unit 3. When the pen is stored, cap 5 is installed on the side of the writing unit 3, which protects the latter from damage. At the same time, the multifaceted shape of the section 8 of the outer surface of the tubular body 1 prevents the formation of a closed chamber when the cap 5 is installed.

Claims (1)

A Fountain Pen containing a tubular body in which a replaceable dye tank is installed with a writing unit protruding from one end of the tubular body, installed at the end of the tank and having a stopper made of elastic material and a cap installed concentrically for air to enter the tank tube and forming a chamber with it for applying pressure dye, characterized in that, in order to increase the manufacturability of the structure, the tube through the landing belt is fixed to the end of the tube of the case to prevent the writing unit from moving inside the tubular body when writing, and the cap is telescopically connected to the outer surface of the tubular body, from which the outer surface is made with a section under the cap from the end of the protruding writing unit.
