Abstract

The tip (1) is made of metal and the insert (3) of synthetic resins. The seat of the ball (4) is formed in the insert. Longitudinal channels (2) which carry the liquid ink from the stick (5) to the ball (4) by capillary action are formed around the periphery of the insert (4) and in the metal tip part (1). The channels (2) formed in the metal provide a much more powerful capillary action than if they were formed in the plastic insert (3). Hence a great improvement in the ink feed to the ball. <IMAGE>

RIVENDICAZIONI 1. Punta per penna a sfera per inchiostri a bassa viscosità, caratterizzata da ciò che il corpo della punta è in metallo e l'inserto (3) in resine sintetiche; la sede della sfera essendo ricavata nell'inserto in resine sintetiche (3), mentre l'afflusso per capillarità dell'inchiostro alla sfera (4) avviene tramite canalini (2) ricavati nella parte metallica (1) del corpo della punta.1. Ballpoint pen tip for low viscosity inks, characterized by that the body of the tip is made of metal and the insert (3) made of synthetic resins; the seat of the ball being obtained in the synthetic resin insert (3), while the inflow by capillarity of the ink to the ball (4) takes place through channels (2) obtained in the metal part (1) of the body of the point. 2. Punta secondo la rivendicazione 1, caratterizzata da ciò che detti canalini (2) ricavati nella parte metallica della punta, sono aperti verso la periferia dell'inserto (3) e sono sagomati trasversalmente (2') in modo da sostenere l'inserto stesso (3).2. Tip according to claim 1, characterized in that said channels (2) formed in the metal part of the tip, are open towards the periphery of the insert (3) and are transversely shaped (2') so as to support the insert himself (3). È noto che gli inchiostri a bassa viscosità a base acquosa, hanno un potere lubrificante molto inferiore rispetto agli inchiostri usati nelle comuni penne a sfera.It is known that low viscosity water-based inks have a much lower lubricating power than the inks used in common ballpoint pens. Penne a sfera con inchiostro liquido (Roller) sono sovente fabbricate in resine sintetiche termoplastiche presentanti basso coefficiente d'attrito, come ad esempio in resine ace-taliche (Delrin) proprio per ovviare agli inconvenienti dovuti allo scarso potere lubrificante dell'inchiostro.Ballpoint pens with liquid ink (Roller) are often manufactured in thermoplastic synthetic resins having a low friction coefficient, such as for example in acetal resins (Delrin) precisely to obviate the drawbacks due to the scarce lubricating power of the ink. I materiali aventi un basso coefficiente d'attrito presentano però l'inconveniente di essere repellenti nei confronti del liquido che li bagna, e da ciò la difficoltà di ottenere una capillarità sufficiente per l'alimentazione dell'inchiostro alla sfera.However, materials having a low coefficient of friction have the drawback of being repellent towards the liquid which wets them, and hence the difficulty of obtaining sufficient capillarity for feeding the ink to the ball. Inoltre le resine termoplastiche hanno meno resistenza dei metalli e le punte a sfera risultano perciò meno robuste rispetto a quelle metalliche.Furthermore, thermoplastic resins have less resistance than metals and ball points are therefore less robust than metal ones. Per ovviare a ciò, con la presente invenzione si propone una punta a sfera, caratterizzata da ciò che il corpo della punta è in metallo e l'inserto in resine sintetiche; la sede della sfera essendo ricavata nell'inserto in resine sintetiche, 5 mentre l'afflusso per capillarità dell'inchiostro alla sfera avviene tramite canalini ricavati nella parte metallica del corpo della punta.To obviate this, the present invention proposes a ballpoint, characterized in that the body of the point is made of metal and the insert is made of synthetic resins; the seat of the ball being obtained in the synthetic resin insert, 5 while the inflow by capillarity of the ink to the ball takes place through channels obtained in the metal part of the body of the point. Il disegno allegato rappresenta in sezione assiale una preferita forma di realizzazione della punta in oggetto, io — La fig. 1 rappresenta la sezione assiale della punta completa di inserto in plastica, con sfera nella posizione prima della ribordatura e dopo la ribordatura.The accompanying drawing shows in axial section a preferred embodiment of the tip in question, I - FIG. 1 represents the axial section of the tip complete with plastic insert, with the ball in the position before the flanging and after the flanging. — La fig. 2 è la sezione parziale della sola parte metallica anteriore della punta fatta secondo il piano passante— The fig. 2 is the partial section of only the front metal part of the toe taken along the through plane 15 per II-II in fig. 15 for II-II in fig. 3.3. — La fig. 3 è la vista in pianta dall'alto della fig. 2.— The fig. 3 is the top plan view of FIG. 2. Il corpo della punta 1, in metallo presenta alla sua periferia dei canalini longitudinali 2 che hanno il compito di convogliare l'inchiostro dallo stecchino 5 alla sfera The metal body of the tip 1 has longitudinal grooves 2 on its periphery which have the task of conveying the ink from the stick 5 to the ball 4. 20 Al -centro, è disposto un inserto in plastica 3, che appoggia sulla spalla 2' del corpo 1 e potrebbe presentare un foro assiale.4. 20 In the center, a plastic insert 3 is arranged, which rests on the shoulder 2' of the body 1 and could have an axial hole. L'inserto 3 può essere in resina acetalica (Delrin), in resina aramidica (Vespel) o in politetrafluoroetilene (Teflon), 25 o in qualsiasi altro materiale avente un basso coefficiente d'attrito.The insert 3 can be made of acetal resin (Delrin), aramid resin (Vespel) or polytetrafluoroethylene (Teflon), 25 or any other material having a low friction coefficient. La sfera 4 si appoggia così sull'inserto in plastica 3, mentre l'alimentazione dell'inchiostro passa per capillarità dallo stecchino 5 ai canalini 2 e quindi alla sfera 4. 30 È previsto che la forma dei vari componenti la punta in oggetto possa variare, e in particolare quella dei canalini longitudinali 2, senza uscire dall'ambito di protezione del brevetto.The ball 4 thus rests on the plastic insert 3, while the ink supply passes by capillarity from the toothpick 5 to the channels 2 and then to the ball 4. 30 It is foreseen that the shape of the various components of the tip in question may vary , and in particular that of the longitudinal grooves 2, without departing from the scope of protection of the patent. vv 1 foglio disegni1 drawing sheet
