Abstract

An open-top container receives a dental tool support in the form of an open-bottom cylinder provided with threads around its upper and lower ends engageable with internal threads at the upper end of the container so that the support may be held by the container in either an upper or lower position. A cap threadedly engages the tool support to seal the assembly when the support is in its lower position.

Claims

1. A sterilizing container device for dental tools comprising:

a container body consisting of a first supporting part having a head adapted to locate and support dental tools separately thereon and a second receiving part adapted to receive and support said first part in a first position wherein the latter is received within said second part and means sealingly securing said parts in said first position wherein only said head is outside said receiving part, and a second position wherein substantially all of said supporting part extends upwardly from the upper end of said receiving part; and

a closure cap closing said head and being sealingly secured to said first part over said head in an airtight manner.

2. The device according to claim 1 wherein both the container body and the cap are provided with gripping embossments.

3. The device according to claim 1 wherein the container body is of right-cylindrical shape.

4. The device according to claim 3 wherein the interengageable means for securing the container body to the tool support comprises a screw thread formed at the end of the container body opposite its closed end and a first complementary thread at the bottom of the tool support and a second complementary thread near the top of the tool support, a gripping embossment integrally formed on the head of the tool support above said second complementary thread.

5. The device according to claim 4 wherein the interengageable means for tightly securing the cap to the support head comprises complementary screw threads formed on the cap and above the embossment of the head.

6. The device according to claim 5 wherein the tool support comprises a cylindrical wall depending from the head which is of circular form with the wall being arranged to extend within the container body.

7. The device according to claim 6 wherein the tool support wall comprises at least one set of openings.

8. The device according to claim 6 or claim 7 wherein the head of the tool support has a plurality of axially extending openings, each being adapted to receive and locate a dental tool.

9. The device according to claim 8 wherein the openings in the tool support head are countersunk, each comprising an upper length of larger diameter opening to the outer face of the head and a lower length of smaller diameter opening to the inner face of the head, said bores being adapted to receive dental tools so that cutting portions of such tools can protrude below the inner face within the confines of the cylindrical wall of the support while head portions can protrude above the outer face of the support head.

10. The device according to claim 8 wherein at least two of said bores for the tools are of different type or dimensions.

11. The device according to claim 6 wherein the upper face of the tool support head comprises a diametral step defining two semicircular portions, one being raised relative to the other.

12. The device according to claim 11 wherein each semicircular portion has an equal number of bores for receiving dental tools.
