In I ¹ Ig. 2 the front view of a tube perfected according to the invention.

Oas known tubes 1 made of any material (Fig. 1) has the pair of stop pieces 1 and 1 ', which the elastic pressure of the spring 3 provide the necessary counterforce ".

When you pull the tube out of the ballpoint pen, the spring J appears to fall out by sliding down in the direction of arrow 4.

According to the furnace, in addition to the pair of stops 1 and 1 ', a second pair 2 and 2' is provided, which in small Distance from the first pair and is arranged such that between the first and the second pair at least the first Start winding 3 'of leather 3 can be inserted. In this way it is possible that the spring falls out and this makes the pen unusable.

According to a variant, the two pairs of stop pieces consist of two adjacent annular projections which delimit a recess between each other into which the first turn of the spring inserts and is thereby held.

Of course, the shape and arrangement of the aforementioned The holding means and the nature of the material forming the tube and the holding means themselves can be arbitrary, without thereby stepping out of the scope of protection of the present innovation.
