Abstract

SUMMARY OF THE INVENTION: The movable hard part of the reservoir is made in the form of a piston with a writing element in the form of a capillary tube. The lower part of the outer decorative casing is made in the form of a removable cap, in the opening and in the inner cylindrical part of which there is a movable capillary tube and a piston with a corrugated elastic web. 1 il.

Description

The invention relates to stationery, in particular to handles with a reservoir. An automatic pen is known, containing a rigid decorative shell, a body, a reservoir with a writing substance, a writing element.

The disadvantage of this device is low reliability.

Closest to the present invention is a handle containing an outer decorative casing, a reservoir consisting of movable and fixed rigid parts connected by a corrugated elastic web, a writing element fixed to the movable rigid part of the reservoir, and a valve located on the side of the corrugated elastic web the end of the fixed rigid part of the tank.

The disadvantage of this device is low reliability and inconvenience in operation.

The aim of the invention is to increase reliability in operation.

The goal is achieved in that, in a known device comprising an outer decorative casing, a reservoir consisting of movable and fixed rigid portions connected by a corrugated elastic web, a writing element fixed to the movable rigid portion of the reservoir, and a valve located on the side of the corrugated elastic jumpers at the end of the fixed rigid part of the tank, the movable rigid part of the tank is made in the form of a piston with a writing element in the form of a capillary tube and the lower part of the outer decor tive shell is formed as a removable cap, and a hole in the inner cylindrical portion which is movably mounted capillary tube and a piston with a corrugated elastic crosspiece.

When pressing the writing element, the end of which protrudes from the conical part of the cap, the piston moves upwards, squeezing the writing liquid through the capillary hole due to the deformation of the elastic corrugated web. With

raising the handle and releasing the end of the writing element, the corrugated elastic web is straightened, moving the piston down and thereby creating a vacuum in the web of the web. Under the action of this vacuum, the valves are lowered, opening the holes, and the writing fluid enters the cavity of the corrugated elastic web. The writing fluid does not spill out of the writing element due to adhesion forces in the capillary orifice. This ensures the reliability of the handle.

The drawing shows the proposed handle, cut.

The writing element 1 with a capillary tube 2 is hermetically connected to the piston 3. The latter, with a spacer ring 4, is tightly connected with a bellows 5 to a corrugated elastic web 6, spring-loaded bellows, the second end of which is hermetically connected to the ledge 7 of the tank 8, in which grooves 9 are made and 10. The tank 8 is made with holes 11, in the conical grooves 12 of which are installed conical valves 13 with spring-loaded elements 14. The spade 15 of the tank 8 is tightly connected to the corrugated tank 16 of elastic material The air passes through the aperture 17 with a plug 18. On the outer surface of the tank 8, cuttings 19, 20 are made with left and right threads, on which decorative shells 21 and 22 are screwed. In the outer decorative shell 21 there is a hole 23 through which the writing element 1 passes. In the piston 3,

grooves 24 for fastening the spring elements 14. The handle works as follows.

The reservoir 16 is poured into the reservoir 16 through the filling opening 17. By unclenching the corrugated elastic web b, the volume between the groove 10 of the reservoir 8 and the piston 3 is filled. When writing by pressing the writing element 1, the writing substance enters through the capillary 2. In this case, as the writing fluid is consumed, the bellows 5 is compressed. With the separation of the writing element from the plane of the bellows 5, expanding, sucks the writing fluid from the reservoir 16 through the holes 11 and conical valves 13.

The economic effect is achieved by increasing the reliability of the device.
