MALAXEUR AMELIORE POUR MALAXER DESIMPROVED MIXER FOR MIXING
CIMENTS DENTAIRES EN VRAC OU EN CAPSULES. DENTAL CEMENTS IN BULK OR IN CAPSULES.
La présente invention concerne le domaine du malaxage de ciment à usage dentaire. Le malaxage des ciments dentaires en général The present invention relates to the field of cement mixing for dental use. Mixing dental cements in general
se fait sur une plaque avec une spatule. is done on a plate with a spatula.
L'opérateur mélange donc une poudre et un liquide, jusqu'à l'obtention d'une consistance: - fluide avec les ciments de scellement, quel que soit la nature chimique, - crémeuse avec les pâtes pour obturation canalaire (ZOE), - ferme à "mastic ", avec la nouvelle The operator therefore mixes a powder and a liquid, until a consistency is obtained: - fluid with the sealing cements, whatever the chemical nature, - creamy with the pastes for canal filling (ZOE), - firm to "putty", with the new
génération de ciments CVI.generation of CVI cements.
Le malaxage peut aussi se faire dans des capsules; une petite poche de liquide est alors rompue The mixing can also be done in capsules; a small pocket of liquid is then broken
à l'intérieur de la capsule contenant la poudre. inside the capsule containing the powder.
classiquement le malaxage s'opère à l'aide d'un vibreur (du type à malaxer les capsules d'amalgame). Les capsules sont bloquées entre les deux parties d'une fourche qui entre alors en vibration pendant 10 à 20 secondes. Un malaxeur centrifuge planétaire est habituellement destiné à recevoir au moins un godet comprenant un fond et des parois latérales périphériques conventionally the kneading is carried out using a vibrator (of the type for kneading the amalgam capsules). The capsules are blocked between the two parts of a fork which then vibrates for 10 to 20 seconds. A planetary centrifugal mixer is usually intended to receive at least one bucket comprising a bottom and peripheral side walls
de forme générale cylindrique.generally cylindrical.
Il comporte un double-bras mobile entraîné It has a mobile, driven double arm
en rotation autour d'un axe principal. rotating around a main axis.
Un exemple connu de malaxeur est décrit dans le brevet francais FR2718058 du demandeur. Dans ce brevet, on propose l'utilisation de capsules pour la préparation de ciment ou d'amalgame. La capsule est A known example of a mixer is described in French patent FR2718058 of the applicant. In this patent, the use of capsules is proposed for the preparation of cement or amalgam. The capsule is
logée dans une cavité fermée par un couvercle. housed in a cavity closed by a cover.
Le brevet francais FR2668079 du demandeur décrit un exemple de godet mélangeur pour un malaxeur centrifuge planétaire, et malaxeur recevant de tels godets. Le but de l'invention est de rendre ce type d'équipement plus polyvalent en permettant le malaxage de ciments contenus dans des capsules, ainsi que de French patent FR2668079 of the applicant describes an example of a mixing cup for a planetary centrifugal mixer, and mixer receiving such cups. The object of the invention is to make this type of equipment more versatile by allowing the mixing of cements contained in capsules, as well as
ciments non conditionnés.unconditioned cements.
A cet effet, le bol présente une cavité pour recevoir un mini-bol et un canal perpendiculaire à un For this purpose, the bowl has a cavity to receive a mini-bowl and a channel perpendicular to a
axe radial pour recevoir une capsule. radial axis to receive a capsule.
Selon une première variante, les dimensions de ce canal sont sensiblement égale à l'encombrement According to a first variant, the dimensions of this channel are substantially equal to the size
extérieur de la capsule.outside of the capsule.
Selon une deuxième variante, la longueur de ce canal est supérieure à la longueur de la capsule afin de permettre un déplacement provoquant des chocs contribuant à un mélange efficace du ciment, ce qui est intéressant pour les capsules ayant un petit volume interne ne permettant pas un brassage suffisamment efficace. L'invention sera mieux comprise à la lecture According to a second variant, the length of this channel is greater than the length of the capsule in order to allow displacement causing shocks contributing to an efficient mixing of the cement, which is advantageous for capsules having a small internal volume which does not allow a sufficiently effective brewing. The invention will be better understood on reading

L'invention concerne un malaxeur comportant un bol de malaxage (1). Ce bol est représenté en vue de The invention relates to a mixer comprising a mixing bowl (1). This bowl is shown for
dessus en figure 1 et en vue de coupe en figure 2. above in FIG. 1 and in section view in FIG. 2.
Il présente une forme générale cylindrique à section elliptique. Il est usiné ou moulé pour présenter It has a generally cylindrical shape with an elliptical section. It is machined or molded to present
un moyeu central (2) de forme elliptique. a central hub (2) of elliptical shape.
Le fond (3) du bol présente une première cavité (4) pour recevoir une capsule (5). Cette cavité (4) est orientée transversalement, c'est-à-dire perpendiculairement à un axe radial. Cette cavité (4) présente une forme complémentaire de la forme de la capsule (5), de façon à assurer son calage. Le bol est réalisé en alliage métallique de faible densité (Aluminium titane) de sorte que l'on puisse ajuster sa masse afin qu'elle soit équivalente à celle de la tare The bottom (3) of the bowl has a first cavity (4) for receiving a capsule (5). This cavity (4) is oriented transversely, that is to say perpendicular to a radial axis. This cavity (4) has a shape complementary to the shape of the capsule (5), so as to ensure its wedging. The bowl is made of low density metal alloy (Aluminum titanium) so that its mass can be adjusted so that it is equivalent to that of the tare

L'alliage métallique peut également contribuer à éliminer la chaleur dégagée lors de la The metal alloy can also help remove the heat given off during
préparation des ciments en vrac.preparation of bulk cements.
La cavité est prévue dans le prolongement du grand axe du moyeu. Pour parfaire l'équilibrage, le fond (3) présente du coté opposé à la capsule une autre cavité de section elliptique (6), orientée verticalement, pour recevoir un mini-bol (6) permettant de préparer des composants qui ne sont pas conditionnés dans des capsules. Le mini-bol présente une forme extérieure complémentaire à la forme de la cavité pour assurer un bon calage et une bonne transmission de la chaleur. La figure 3 représente une vue de détail du mini-bol (6). Pour faciliter l'extraction du contenu du mini-bol, celui-ci comporte un bouchon-piston (8) The cavity is provided in the extension of the major axis of the hub. To complete the balancing, the bottom (3) has on the side opposite the capsule another elliptical section cavity (6), oriented vertically, to receive a mini-bowl (6) allowing to prepare components which are not conditioned. in capsules. The mini-bowl has an external shape complementary to the shape of the cavity to ensure good wedging and good heat transmission. Figure 3 shows a detailed view of the mini-bowl (6). To facilitate the extraction of the contents of the mini-bowl, it has a plunger stopper (8)
prolongé par un bec (9).extended by a spout (9).
