Description

1 2658741

  The present invention relates to instruments for applying a liquid, including instruments for applying a liquid cosmetic product, an ink writing instrument, etc. As an instrument for applying a liquid, there is known in the prior art an instrument which comprises a central drawing-line element resembling a tube of circular cross-section and a cap of the drawing-line made of porous elastic material

  placed on the outer periphery of the central element.

  The disadvantage of this instrument is that it cannot correctly draw both a plane and a line and that it is difficult to spread the discharged liquid as far as the rear part of the cap which is distant from the anterior outlet orifice of the central element. The present invention relates to a liquid application instrument, capable of correctly applying the liquid both on a plane and along a line and allowing the discharged liquid to spread easily at a distance as far as the posterior part of the cap of the line drawing distant from the outlet orifice, front side,

  the central element forming the puller.

  According to the present invention, the instrument comprises a central drawing-line element, comprising a tube on the lower side and on the two external lateral faces of the tube, two projecting fins, a cap of the drawing-line made of porous elastic material being placed on the outer periphery of

the central element.

  The present invention will be well understood

  during the following description made in connection with

  the accompanying drawings in which: Figure 1 is a vertical sectional view of a main part of the instrument; Figure 2 is a sectional view taken along line A-A of Figure 1; and

  Figure 3 is a perspective view of

  the central element forming the puller.

  First of all, a central element 3 in the form of a line puller is made of a plastic material and comprises at its lower end a tube 1 On the two lateral faces of the tube 1, flat fins 2 are axially projecting In addition , the element 3 comprises an engagement tube 6 above the tube 1, a connection tube 8 above the tube 6 by means of a collar 7 and a projection

  9 on the outside of the tube 6.

  The element 3 is fixed in the opening of the lower end of a main barrel 10, the connection tube 8 being pressed into it. In addition, the element 3 internally has an ink guide hole 12 which communicates with an ink tank 11 located in the barrel 10 The hole 12 opens at the lower end of the tube 1 The cover 4 of the central part 3 made of porous elastic material, for example in sponge, is in the form of a hollow bag, and is placed on the outer periphery of the element 3 extending to a position located below the flange 7 On the outer periphery of the lower end of the main barrel 10, a front barrel 13 is placed so as to be able to substantially cover the upper half of the cap 4 The cap 4 is fixed by being placed between the inner face of the front barrel 13 and the outer periphery of the engagement tube 6 of the element 3 At a place of the inner side of the front barrel 13, axially offset from the location of the engagement projection 9, an engagement projection 14 is formed by cutting Consequently, the cap 4 is not only placed in a fixed manner between the front drum 13 and the tube 6 but is also secured by the engagement projection 9 of the tube 6 and the engagement projection 14 of the front barrel 13 for fear that it leaves the central element 3 The ink from the reservoir 11 is discharged by the guide hole 12 and the opening in the lower end of the tube 1 then permeates the cap 4, which in turn allows the liquid to be applied. Furthermore, with the fins 2 projecting from the outside face. of the tube 1, a space 5 is formed between the external face of this tube and the internal face of the cap 4, and, the liquid application instrument being inverted, the liquid flows through the space 5 until '' at the rear of tube 1 to impregnate not only ent the anterior end of the cap 4 but also

all together.

  In operation, when making a line, one can use the parts of the cap 4 which

  correspond to the two lateral edges of the fins 2.

  When painting a plan, you can conveniently use the parts that are vertical for

  compared to those used to obtain a line.

  When the cap 4 is placed on the outer periphery of the central element 3, with the fins 2 projecting from this element, a space 5 is formed between the outer face of the tube 1 and the inner face of the cap 4, and the liquid can flow

easily through space 5.

  The instrument of the present invention makes it possible to form both a line and a plane in a convenient manner, but also offers the advantage that the liquid can spread over the whole of the cap without being on one side of its anterior end to allow good application of the liquid without the

production of burrs.

  The present invention is not limited to the exemplary embodiments which have just been described, it is on the contrary liable to modifications and

  variants which will appear to those skilled in the art.
