I PACKING OF DENTAL AMALGAMS Filed Dec. 5, 1932 FIG.1

Patented Aug. 28, 1934 PACKING F DENTAL AMALGAMS Eugene Alilaire, Paris, France Application December 5, 1932, Serial No. 645,870 In France February 4, 1932 2 Claims. (01. 206-47) The amalgams utilized in the dental art and which are composed of a certain quantity of mercury allied to other metals in a pulverous state are prepared by practitioners at the moment 5 when they are about to be used. On account of the rapidity with which the manipulations must be carried out it is practically impossible, even for a skilful practitioner, to prepare an amalgam in which the proportions are strictly observed with a minimum amount of waste.

' The object of the present invention aims at providing a double container intended to hold, separately, the strictly proportioned doses of the constituent parts of a dental amalgam, which container makes it possible to protect. said constituent parts against the action of atmospheric agencies and to unite them at the moment when they are about to be used by breaking the double container in order to obtain rapidly an amalgam 0 the proportions of which have been strictly pre:

determined.

In the attached drawing a form of embodiment of the double container which forms the subject matter of the present invention has been shown solely as an example:

Figure 1 is a side view of the container;

Figure 2 is. a longitudinal section of Figure 1.

'In this example of a form of embodiment the double container is composed of a glass tube 1 39 strangulated at point 2 in such a manner as to form twoseparate cavities 3 and 4 which are welded with a blow pipe after the strictly dosed quantities of mercury .5 and of metallic powder 6 have been introduced into said cavities.

By means of this form of packing the constituent portions of the amalgam are sheltered against outside agencies and remain thoroughly separated from one another until the moment when they are to be utilized. In order to prepare a dose of amalgam (the dose necessary for one operation), it is sufiicient to break ofi each extremity of the container and to mix the constituent parts in the usual manner after having extracted them from said container. 7

It is to be understood that the form of packing hereinabove described 7 and the embodiment shown in the drawing, are given solely as examples and thatv the invention is not so limited but may be otherwise embodied within the scope of the following claims and that it may be constituted by any other suitable substance other than glass.

What I claim is:

l. A package for the reception of constituents of dental amalgams, comprising a glass tube divided into two sealed compartments by a glass partition integral with the tube, each of said compartments receiving a measured constituent of an amalgam, the said partition being obtained by a constriction in said tube, the exterior extremities of the compartments being drawn out and sealed.

2. A package for the reception of constituents of dental amalgams, consisting of means defining a onepiece, two-compartment glass receptacle, the said means comprising a glass tube, and a glass partition integral with said tube and formed by a constriction therein, dividing the said tube into two separate compartments, completely sealed from each other, each being adapted to receive a measured constituent of an amalgam, the exterior extremities of the compartments being sealed.
