These seven strengths represent Conid’s seven ultimate qualities that provide our Bulkfillers with their unique, reliable and innovative characteristics.
Indisputably the most important aspect of every fountain pen, every single one of our nibs receives an equal amount of detailed attention. These Peter Bock nibs are all individually tuned and grinded to our client’s personal preferences under the supervision of our nib specialist’s critical eye. A wide variety of premium materials aims to meet every single customer’s demands. Our nibs come in stainless steel, titanium, gold, gold with a rhodium coating – also known as “white gold” and last but not least: our stealth nibs.
Next to their balanced look, fit for any special occasion or daily handwriting, our Bulkfillers all hold an efficient and well-thought-out design. The cap band at the end of the cap, for example, is sturdily shrunk onto the cap. In that way, the band provides the screw-threading with additional strength so that no cracks in the cap will occur due to continuous (un)screwing of the cap.
Secondly, a built-in stick-slip breaker ensures easy breakaway of the piston. This is an axial cam on the closure nut that works together with the piston when unlocking it. The rotation of the piston gets transferred to the axial stroke and eliminates the remaining stick-slip. This guarantees a smooth down-movement of the piston when filling or flushing your Bulkfiller.
The third strength highlights that a Conid Bulkfiller is not only easy to use but also easy to fill, flush and dismantle. The displacement speed – inherent in the Bulkfiller system – guarantees fast and efficient flushing. The turbulence created by quickly pushing the piston down ensures all remaining ink is removed after 3 to 4 flushing movements.
All sealing elements are standard O-rings, allowing for easy disassembly without heating up or special tooling. The O-ring at the top of the piston rod makes the ink reservoir leak-tight once the filling knob has been completely closed. This eliminates the risk of leakage caused by variations in air pressure and/or temperature e.g. during an aeroplane journey.
Created to last for eternity, all of the constructional segments of our Bulkfillers are made from high-quality titanium. One of our showpieces on this matter is our clip. The Conid clip is manufactured from one solid titanium bar, instead of opting for a sheet-metal clip.
This offers an obvious structural benefit which renders in a practically indestructible clip that lasts longer than a lifetime. Its lightweight and various elegant designs make the clip a unique and signature part of the Bulkfiller.
Maximum ink capacity
For our fifth strength, we believe that maximum ink capacity allows for maximum use. The barrel of our Bulkfillers supports an intake of up to 6 ml of ink, without cutting down on ultimate writing comfort.
This is due to the filling mechanism in the back, which is kept to a minimum size because the small piston rod slides through the piston which is anchored at the barrel end-plug. In that way, the main ink reservoir is exceptionally large, while incorporated in a very slim and ergonomic fountain pen.
Patented Bulkfiller system
Our CONID Bulkfiller has a patent pending syringe filling system designed by Fountainbel, our founding father. The Bulkfiller system consists of a syringe filler on which the syringe rod can be engaged to the piston prior to filling, and disengaged from the piston after filing.
It allows huge ink intakes at minimum build- in length of the filling mechanism. Read more about the history of the Bulkfiller system.
Strong and durable
The seventh strength states that all parts – except for the nib and feed – are completely CNC
machined and there is no glue involved whatsoever. The static and dynamic sealing elements are standard off-the-shelf items. The piston rod is made of stainless 316 steel, the other metal parts are made of titanium. This not only allows for very high accuracy in assembly but also in writing experience.
Inside the closure nut, there is no seal. Instead, there is a gap between the rod and the hole
inside the nut to allow air to travel in and out the barrel at the backside of the piston on the
The piston seal is an X-ring, which has less stick-slip compared to an O-ring,
and allows for a small amount of silicone grease to be applied to the central groove, which
improves lifetime magnificently.
