RU118186U1 - UNIVERSAL TUBA NOZZLE FOR LIGHT-CURING COMPOSITE MATERIAL - Google Patents

Abstract

 A universal tube nozzle for a light-cured composite material, contains a housing, a retention element, a contact pad, a ledge, a visor, a cap with retention elements, characterized in that the case is made in the form of a trapezoid with rounded edges and retention elements or any shape, containing in the lower part a blind hole, smoothly or abruptly passing into a through hole of a smaller diameter, extending in the center of the contact area or closer to the ledge, located in the upper part of the housing, also in hney portion of the blind hole washer can be positioned straight or conical internal face, in its turn at the end of the ledge is visor, the diameter of the through hole is equal to the length of the ledge, over the device puts the cap from the retention elements trapezoidal or arbitrary shape.

Description

This utility model relates to medicine, namely to dentistry, and can be used for dispensing light-cured composite material.

The closest analogue of the nozzle to the tube for a light-cured composite material is known, comprising a body with retention elements on the outer surface, having a through channel with thread for screwing onto the tube, the top of the nozzle body is made in the form of a step 1-2 to 2.5 mm high with a visor width of 0, 1-1.0 mm, and a horizontal contact pad with an outlet for the through channel, and a cap with retention elements on its outer surface covering the nozzle body [utility model No. 88946, IPC A61C 5/04 of 05/29/2009].

The disadvantages of this device include the inability to use on tubes with missing threads on the seat.

The technical result of this utility model is the ability to use on tubes with missing thread on the seat.

The technical result is achieved due to the fact that the universal nozzle on the tube for light-cured composite material contains a housing, a retention element, a contact pad, a ledge, a visor, a cap with retention elements, characterized in that the case is made in the form of a trapezoid with rounded edges and retention elements or arbitrary shape, containing a blind hole in the lower part, for placement on the tube, smoothly or abruptly passing into a through hole of a smaller diameter, extending in the center of the contact plate pads or closer to the ledge located in the upper part of the housing, also in the upper part of the blind hole there may be a washer with a straight or conical inner face, which serves for more rigid fixation on the tube, in turn, at the end of the ledge there is a visor that serves to accurately dose the portion material, and the diameter of the through hole is equal to the length of the ledge, a cap with retention elements of a trapezoidal or arbitrary shape is put on top of the device, which protects the composite material from pollution.

A universal nozzle on a tube for a light-cured composite material (Figure 1 - Universal nozzle, Figure 2 - A longitudinal section of a General view) contains a housing (1), a retention element (2), a contact pad (3), a ledge (4), a visor ( 5), a cap with retention elements (6), characterized in that the housing (1) is made in the form of a trapezoid with rounded edges and retention elements (2) or of arbitrary shape, containing a blind hole (7) in the lower part that smoothly or sharply transitions into the through hole (8) of a smaller diameter, centered at the contact area (3) or closer to the ledge (4), located in the upper part of the housing (1), also in the upper part of the blind hole (7) there may be a washer (9) with a straight or conical inner face, in turn at the end ledge (4) is a visor (5), and the diameter of the through hole (8) is equal to the length of the ledge (4), a cap is put on top of the device with retention elements (6) of a trapezoidal or arbitrary shape.

A universal tube nozzle for a light-cured composite material can be made of either polymeric materials or metal or a combination thereof.

The procedure for working with a universal nozzle on a tube for a light-cured composite material is as follows. The nozzle is put on a tube with a light-cured composite material, remove the cap and squeeze a portion of the composite material. When the material reaches the peak of the ledge, it is cut with a tool, relying on the contact pad. The separated portion of the material is used for filling.

The use of a universal nozzle on a tube for a light-cured composite material allows the use of tubes with missing threads on the seat.
