Ava-W706 GABRIEL 2E ITER- AMALGAM TRITURATION DEVICE BACKGROUND OF THE INVENTION the mere contamination of the atmosphere or air withmercury is dangerous to those in the environment.
SUMMARY OF THE INVENTION It is, therefore, an important object of the present invention to overcome the above-mentioned difl'iculties, permitting the quick and easy mixing or trituration of amalgam by the conventional manual squeezing procedure, but wherein the excess mercury is positively retained against contact with the operators skin, and further effectively shielded from contaminating the environmental atmosphere.
It is another object of the present invention to provide an amalgam trituration device having the advantageous characterisitcs mentioned in the preceding paragraph which is extremely simple in construction, foolproof in operation, and which can be economically manufactured for sale at a reasonable price.
Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.
The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top perspective view illustrating an amalgam trituration device constructed in accordance with the teachings of the present invention.
FIG. 2 is a sectional view taken generally along the line 2-2 of FIG. 1.
FIG. 3 is an elevational view illustrating a trituration device of the present invention in an operative condition of use.
FIG. 4 is a partial sectional view taken generally along the line 4-4 of FIG. 3.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the drawings, andspecifically to FIGS. 1 and 2 thereof, a trituration device of the present invention is there generally designated l0, and may be generally circular in outline configuration or of other suitable outline configuration, as desired. The trituration device is of generally laminar construction, including a porous layer 11 of flexible sheet material, such as cotton cloth, or other suitably woven fabric. The layer 11 may, if desired, be the same as now conventionally employed as a squeeze cloth in the prior art amalgam trituration procedure.
An additional layer 12 is disposed in facing engagement'with the layer 11, and may be congruent thereto. The layer 12 is substantially impervious to fluid passage therethrough, and of a flexible sheet material, such as plastic film. In the illustrated embodiment the layers 11 and 12 are circular, and this may be advantageous in accommodating to the manual squeezing operation, wherein the assembled lamination I0 is wrapped tightly around the amalgam with the porous layer or cloth against the amalgam, the gathered marginal edge of the assembly being twisted by one hand and the bulbous amalgam-containing central portion being held by the other hand.
This procedure tightens the device 10 about the con- I tained amalgam, effecting trituration thereof and squeezing out the excess mercury through the porous inner layer or cloth 11. However, the expressed mercury cannot get through the impervious outer layer or plastic sheet 12, and is so retained for disposal. This condition is shown in FIG. 4, wherein the triturated amalgam is designated 13 and the expressed mercury is designated 14, the amalgam being disposed centrally within the porous layer 11 and the mercury disposed between the porous layer and impervious layer 12.
Further assuring the convenient retention of the expressed merucy I4 is the securement together of the layers 11 and 12 along a closed configuration or securement line I5, see FIG. I. This closed configuration may be of any suitable shape, preferably similar to that of the layers 11 and 12, but not necessarily so. In practice, it has been found advantageous to employ a th'ermoplastic material for layer 12, and to adhesively secure the layers 11 and 12 along an endless or closed configuration of securement line 15, as by a thermoweld, best seen in FIG. 2. However, other suitable securement means may be employed along the securement line 15.
From the foregoing it will now be appreciated that the instant invention'provides an amalgam trituration device which effectively prevents mercury contamination of the users skin as well as of the air or surrounding environment, while permitting of quick and easy trituration by essentially the conventional procedure, and which otherwise fully accomplishes its intended objects.
Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention.

l.
