  • DENTAL MIXING DEVICE HAVING AN AUTO-ALIGNING MIXING TIP
    Publication number: 20150079539
    Abstract: A dental mixing device with a barrel, a mixing tip, and a plunger. The plunger moves dental material through the barrel where it is mixed using a mixing tip. The mixing tip includes an auto-aligning fitting female element configured to align with an auto-aligning fitting male element of the barrel. This auto-alignment simplifies the attachment between the mixing tip and the barrel. The mixing tip also includes a seal component with a soft material (or component) to insert into the auto-aligning fitting element which is a hard material (or component) to achieve seal. The seal component and auto-alignment fitting element can be combined together into one component instead of two components.
