DISH-LIKE CONTAINER FOR DENTAL DRILLS AND THE LIKE Filed Dec. 29, 1947 InVQRtOY y a r. wmn.

ATT'o KNE) Patented Dec. 20, 1949 UNITED STATES FATENT OFFICE DISHLIKE CONTAINER FOR DENTAL DRILLS AND THE LIKE Walther Roos, Basel, Switzerland Section 1, Public Law 690, August 8, 1946 Patent expires October 24, 1966 2 Claims.

Dish-like containers in use up to the present, in which dentists place their drills or other rod shaped implements, ready for use, comprise a fiat shaped container body, in which are provided one or more compartments formed by recesses having a rectangular horizontal section and containing the different drills or the like. These compartments are provided with vertical side walls and a flat bottom, on which are superposed the drills, so that the upper drills cover the lower ones. If the dentist wishes to withdraw a special headed drill from the said compartment, he must search for the same with pincers among the pile of drills in this compartment, since the heads of the lower drills are not visible.

According to the present invention, this drawback is eliminated by the fact that at the frontal side of the compartment or compartments of the container, against which are directed the rear ends of the drills, there is provided an inclined abutment surface, against which may bear the drills with their rear rod ends, so that the head ends of all the drills are in staggered formation and are clearly visible.

The accompanying drawings show by way of examples different forms of embodiments of the object of the invention.

Fig. 1 is a plan view of a dish-like container according to a first embodiment;

Figs. 2 and 3 show, in a larger scale, a longitudinal section and a cross section along the lines 11-11 and III-III of Fig. 1;

Figs. 4, 5 and 6 show further cross sections, and

Fig. 7 shows another longitudinal section of a further form of embodiment of the container according to the invention.

The dish-like container according to Figs. 1, 2 and 3 includes a fiat shaped container body a comprising four compartments b for longer dental drills and three compartments 0 for shorter dental drills. These container compartments are formed by recesses or depressions of rectangular plan view. Each of these container compartments is provided with an inclined abutment surface b respectively b at its right frontal side as seen in Fig. 1. Inclined surfaces 1: and c are also provided at the two longitudinal sides of the container compartments, whose section line, lying in the central longitudinal plane of the container compartments, slants downwardly from the left hand frontal side. The section lines of the three inclined surfaces b b, b intersect, as shown in Figs. 1 and 2, at a point of intersection 0 which coincides with the deepest point of the corresponding container compartment. The drills of the same length are placed in the container compartments. As a result of a'slight shaking of the container, the drills settle as shown in Fig. 2 with their rear rod ends bearing against the inclined abutment surfaces b, so that the head ends of all the drills are visible, as seen from above, in a staggered formation. The container compartments may have other longitudinal and cross sections than those shown in Figs. 2 and 3. For instance, Figs. 4, 5 and 6 show other sections which may also be taken into consideration and which may be rectangular, semi-circular or polygonal. Fig. 7 further shows that the bottom surfaces of the container compartments, on which the drills rest longitudinally, need not necessarily be inclined, as is the case in Fig. 2, but may also be fiat or horizontal. In any case, however, an inclined abutment surface is provided, for the above stated purpose, at the frontal side of the container compartments, against which are directed the rear rod ends of the drills.

What I claim is:

1. A receptacle for dental drills and the like comprising a substantially fiat shaped body, a recessed compartment of substantially rectangular shape in said body, said compartment having an inclined end portion sloping downwardly toward the center thereof providing an abutment surface for the rear ends of the drills, said compartment having inclined longitudinal sides: sloping downwardly toward the center thereof and intersecting along the central longitudinal axis of said compartment, whereby drills placed in said compartment are held in staggered relationship having the head ends thereof individually visible.

2. A receptacle for dental drills and the like as claimed in claim 1, wherein the line of intersection of the said inclined longitudinal sides slopes downwardly from the end of said compartment remote from said inclined end portion toward said inclined end portion, the deepest point in said compartment being at the point of intersection of said inclined end and the line of intersection of said inclined longitudinal sides.
