Abstract

THE INVENTION CONCERNS A WRITING INSTRUMENT COMPRISING A BODY 1 IN THE FORM OF A FUT HAVING A PART OF LARGE DIAMETER 1A AND A PART OF SMALL DIAMETER 1B BETWEEN WHICH EXTERNAL SHOULDER IS DEFINED ON WHICH A CIRCUMFERENTIAL GROOVE IS FORMED. ON A PREDETERMINED LENGTH, AND AN ORNAMENT RING 4 FIXED IN THE CIRCUMFERENTIAL GROOVE OF THE BODY AND PARTIALLY EXTENDING OUTSIDE THE GROOVE, THE RING BEING OF THE COLOR WHICH INDICATES TO THE USER THAT OF THE INK OF THE THE INSTRUMENT.

Description

The present invention relates to a writing instrument with a ring

  ornamental mounted on the body and, more particularly, the construction of the body of the instrument for mounting the ring on its top, ring having a color similar to that of the ink of the instrument in order to indicate to the user this color,

  and also having an aesthetic effect.

  So far, we have mounted an ornamental ring on

  the body of a writing instrument to indicate the

  ink them and also get a decorative effect. A ring of this type is, for example, mounted by tight fitting or bonded to the body of the instrument by an appropriate adhesive.

  This type of ring must have a significant thickness.

  aunt to make possible its solid mounting on the body of the instrument by tight adjustment or by connection. This is an inherent problem with conventional rings

  ornamental in this type of instrument.

  The object of the present invention is to solve the above problem by proposing: a writing instrument comprising: - a barrel-shaped body having a part of

  large diameter and a small diameter part between them-

  which an outer shoulder is defined on which a circumferential groove is formed which extends axially over a predetermined length, and

  - an ornamental ring fixed in the circular groove

  body and extending partially towards

the outside of the groove.

  The present invention will be clearly understood from the

  reading of the following description made in relation to

  the attached drawings, in which:

  Figure 1 is a perspective view of the part

  previous part of an embodiment of a writing instrument according to the present invention, and Figure 2 is a partial sectional view of

  the anterior end of the embodiment represented

tee in Figure 1.

  An embodiment of a

  writing instrument according to the present invention. He learns

  It will appear that the invention is not limited to this embodiment. In the drawings, the reference 1 relates to the body of the barrel of the writing instrument of the present

  invention, body which is made of plastic material.

  The body 1 has a large diameter part 1a and

  a small diameter part lb contiguous to the part la.

  Between parts la and lb, an external shoulder

  connect in one piece with them. In a place of the shoulder-

  the outside of the body 1, the rear end of the

  part lb of small diameter is covered by the end

  moth before the large diameter part, like this

  la is shown in Figure 2, so that a groove

  circumferential 2 is formed outside the par-

  tie thus covered, the groove 2 extending in the longitudinal direction of the body 1 to open towards

  the front as shown in Figure 2.

  Inside the groove 2, a projection an-

  lc ring is provided on the outer peripheral surface

  lower portion rear portion lb

body diameter 1.

  A ring 4 of slightly elastic plastic material, which serves as an ornamental ring and has a color similar to that of the ink applied by the application element 3 mounted at the anterior end of the body

  1, is fixed inside the groove 2.

  As shown in the sectional view of Figure 2, the ring 4 has substantially the shape of a

  L with a rim 4a extending radially outwards

  laughing, so that this rim has an outer diameter

  smaller than that of the large-diameter part 1a of the body 1. The rim 4a has a color similar to that of the ink to be applied to an object by the element 3, so as to indicate this color to the user. The ring 4 comprises a part 4c in the form of a sleeve having an axial length equal to that of the groove 2. In the inner peripheral wall of the part 4c, an annular groove is formed in which engages

  the annular projection lc of the rear portion of the

  small lb body diameter 1 lb during operation

  assembly of the plastic ring and the body 1.

  Even when the rim 4a of the ring 4 made of material

  plastic material must be extremely thin to con-

  to give an excellent appearance to the writing instrument, it is possible to fix the ring securely on the body of the instrument of the present invention to prevent the ring from detaching from the body even in the case where it is subjected various effects such as shock, heat, etc. The ring 4 of plastic material is fitted with a tight fit in the circumferential groove 2 of the body i

  in such a way that the annular projection lc of the door

  tion lb with small diameter of the body is received in the reason

  ring shape of ring 4, from which it follows that the ring

  It cannot easily be detached from the groove of the body.

  In the case where a more solid connection must be established between the ring 4 and the groove 2 of the body 1, an appropriate adhesive is applied at the location between the

  body ring and groove 1. The circumferential groove

  tielle 2 of the body 1 and the ring 4 of plastic material can have, if necessary, any axial length.
