BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention, a collector cup comprises a hollow vessel or carrier member and a storage column which are joined for use in a dental office or surgery.
In the first instance, it is used as a collector cup for collecting dental amalgam, where the advantage is to eliminate the loss of dental amalgam by means of a novel vessel inverting system.
Secondly, the collector cup for collecting dental amalgam can also hold all other kinds of material in fluid or solid state. In this case, it is a substitute for a conventional Dappen collector which has been used regularly in dental offices.
The storing column is also provided for use jointly with the hollow vessel or carrier member for collecting dental amalgam used also as a Dappen collector.
BACKGROUND ART
We will now explain at the beginning, the first use of the conventional Dappen collector, that is to say, as a collector for collecting amalgam.
Until now the conventional collector used in dental surgery was made simply of separate, interdependent pieces, in which the top part is hollow and holds the amalgam which the practitioner uses. mentioned, is taken with the help of an amalgam syringe, which deposits the contents into the patient's tooth. This operation is repeated as often as necessary, until the filling up of the hollow of the carious tooth is effected.
Normally, all the amalgam is not used, and as a result, the excess becomes waste that needs to be discarded. With the conventional collector, the excess amalgam is put away by tipping the cup in an uncontrolled way.
The inconvenience of this conventional collector, occurs during the tipping operation to remove and store the amalgam, with the danger that the unused amalgam spills instead of entering the receiver, or other kind of receptacle, thereby causing a danger of environmental pollution. It is also to underline that the traditional system of the above collector has also the inconvenience of allowing release of mercury vapours when the amalgam is not hardened, which is a well-known danger. The inconvenience above mentioned, compels the practitioner or his assistant, to lose time with particular attention to this matter.
DISCLOSURE OF THE INVENTION
The advantage of the present invention is that, the collector cup for collecting Dental Amalgam initialy defined for use in a dental surgery, is composed of a main hollow body (1) with notches (4) provided at its upper part which is connected by pins (7) of a pivoting system which is actuated by means of a handle comprising a knurled wheel or knob (5). The system comprises a carrier member (2) of hemispherical shape or variants thereof, as illustrated, which is provided with a stub (3) preventing the rotation of the vessel or carrier member (2) in an undesired direction. At the lower part of the main body (1) there is provided a hollow, socket-like base plug (6) for the hollow body (1), which is the collector of the excess, unused amalgam. This is done consequently as a result of the pivoting of the carrier member (2) above mentioned.
The above mentioned Collector Cup for Collecting Dental Amalgam is characterized in that the pins (7), the vessel (2) with the stub (3) and the knob or handle (5) may be replaced with an assembly or by separate stocked parts.
The above mentioned collector cup for collecting Dental Amalgam is also characterized by the fact that the pivoting system pins (7) can be also made of rivets.
The above mentioned Collector Cup for Collecting Dental Amalgam also is characterized by the fact that the carrier member (2) at its bottom is narrowed to form a trough of generally hemicylindrical shape with a slight bulge in its bottom at the end adjacent stub (3).
The above mentioned Collector Cup for Collecting Dental Amalgam also is characterized by the fact that the vessel (2) can also be eccentrically mounted in relation to the axial center of the main body (1).
The above mentioned Collector Cup for Collecting Dental Amalgam is also characterized by the fact that the hollow socket-like base plug
