DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of writing implements. More specifically this invention relates to a writing implement in the form of a felt tip pen, marker, liner having a casing, in which a reservoir containing a dry or pasty colored pigment is arranged such that it can be soaked with a liquid dissolving and absorbing the colored pigment and in which a writing tip of capillary material is in contact with the reservoir, which contact ensures the delivery of the writing liquid formed of colored pigment and liquid.
2. Prior Art
All kinds of writing implements having a liquid writing material are known. The writing material reservoir may consist of a refillable reservoir or of exchangeable cartridges. In the case of felt tip pens or the like a tampon or similar capillary reservoir is provided in the casing, which when processed is filled with a predetermined supply of ready-to-use writing material.
The former systems present difficulties for various reasons. Refillable fountain pens having a suction system are hardly used today due to the expenditure and the complicated refilling systems involving the danger of soiling. The cartridges widely spread instead pose environmental problems as regards the waste resulting from the empty cartridges and the packages thereof. Furthermore, the shops have to store corresponding cartridges with varying colored pigments.
Writing implements having a writing material reservoir incorporated into the casing and filled when processed with the writing material, have the drawback that the writing material supply is relatively limited. Another substantial drawback consists in that prolonged storage includes the danger of drying out, so that the writing implement is no longer usable or fails early before the filled-in pigment supply is actually consumed.
SUMMARY OF THE INVENTION
It is the object of this invention to encounter the indicated problems in a simple and effective manner. According to on aspect of the invention there is provided a writing implement in the form of a felt tip pen, marker, liner having a casing, in which a reservoir containing a dry or pasty colored pigment is arranged such that it can be soaked with a liquid dissolving and absorbing the colored pigment and in which a writing tip of capillary material is in contact with the reservoir, which contact ensures the delivery of the writing liquid formed of colored pigment and liquid characterized in that in the casing, in series arrangement with the reservoir containing the dry colored pigment, a reservoir is arranged which can be replenished and/or refilled and absorbs the dissolvent liquid on one side thereof and a writing liquid reservoir is arranged on the other side thereof, and that at least one connecting element having capillary action and penetrating the reservoir containing the colored pigment is provided, which element projects into both the replenishable and/or refillable liquid reservoir and the writing liquid reservoir.
This problem is solved substantially in that in addition to the writing material supply which is in direct contact with the writing tip a colored pigment supply, on the one hand, and a liquid reservoir, on the other hand, are provided separately in the casing, which are in capillary flow communication with one another and with the writing material supply.
A special advantage is represented by the fact that the colored pigments of the colored pigment supply are dissolved or absorbed by and mixed with the liquid as according to the consumption of the writing material resulting from the use of the writing implement. In this case, the writing material reservoir only has the function of providing for an additional mixture and uniform supply of the writing liquid to the writing tip.
The writing liquid can virtually be produced by the user of the writing implement himself when he uses the writing implement for the first time. For this purpose, it is only necessary to fill a predetermined amount of suitable liquid into the casing o
