Embodiment Construction

[0054] figure 1 One embodiment of the dispensing device 10 of the present invention is shown in storage mode. The device shown has a cannula 11 received on the device. In the illustrated storage mode, the cannula 11 is releasably mounted on the device. Thus, this device mode allows, for example, the user to remove and / or replace the cannula 11 . The device also has a container 12 with two chambers (not shown) containing the two dental substance components and pistons 13a, 13b placed in the chambers. Pistons 13a, 13b are movable within the chamber to extrude the dental substance from the chamber towards the outlet. Additionally, in storage mode, a valve (not shown) closes the outlet of the device.

[0055] Although this example shows a device 10 having a chamber with two pistons, the skilled artisan will appreciate that a device with only one chamber with one piston, or a device with multiple chambers with multiple pistons, would work equally well with the present invention...

Abstract

A dispensing device for a dental substance is provided which has an outlet for the dental substance, and a valve for opening and closing the outlet. The device is switchable between a storage mode and an operative mode. In the storage mode a cannula is locked in the device and the valve opens the outlet, and in the storage mode the cannula can be released from the device and the valve closes the outlet. The device may facilitate handling and may be relatively inexpensive.

Description

technical field [0001] The present invention relates to a dental substance dispensing device, in particular to a dispensing device which is switchable between a storage mode and a use mode and which can be used with a replaceable cannula. Background technique [0002] Dental substances are typically provided in packages containing sufficient quantities of the substance for multiple applications. Dentists typically use portions of these substances to apply in the patient's mouth. A dentist may, for example, place a portion of the dental substance on the pad or in the hole and use dental equipment to apply it to the patient's mouth. A dental impression tray can be filled, for example, with dental impression material and then placed in the patient's mouth to obtain a dental impression through the patient's teeth. In many cases, however, the dental substance can also be placed in the patient's mouth directly through the packaging containing the dental substance. A variety of ...
