Rinseable splash shield and method of use
DC CAFCFirst Claim
1. A mixing machine for mixing a liquid contained in a vessel having an opening, the mixing machine comprising:
- a holder coupled to the mixing machine, the holder proportioned to receive a vessel;
a rotatable mixing element extendable through the opening into the vessel positioned in the holder, for mixing the contents of the vessel;
a motor operatively coupled to at least one of the holder and the mixing element to effect axial translation of the mixing element between first and second positions within the vessel, the mixing element positioned further from the opening when in the first position than when in the second position;
a shaft; and
a splash shield slidable on the shaft between first and second positions, the splash shield in the second position positionable covering the opening of the vessel and being unrestrained against sliding movement on the shaft in a direction away from the opening, the splash shield having sufficient mass to retain the vessel within the holder during relative axial movement of the mixing element and vessel from the first position to the second position when liquid is present in the vessel.

Abstract
The present application describes a method for rinsing a splash shield. A vessel containing contents to be mixed is positioned in a mixing machine, and a splash shield is positioned over the opening of the vessel. After the material within the vessel is mixed by a mixing element, the splash shield is separated from the vessel and rinsed by a nozzle on the mixing machine. In another embodiment, a vessel containing contents to be mixed is positioned in a holder on a mixing machine, and a splash shield (which may or may not be rinseable) is positioned over the opening of the vessel. The contents of the vessel are mixed using a mixing element. During and/or after mixing, opposed relative movement of the mixing element and vessel may occur, creating an upward lifting force on the vessel. The weight of the shield is sufficient to overcome this upward lifting force on the vessel and thereby causes the vessel to remain seated in the holder.

6. A method for retaining a vessel in a holder while mixing contents of the vessel, the method comprising the steps of:
-
providing a vessel containing contents to be mixed, the vessel including an opening; further providing a mixing machine having a holder on the mixing machine for receiving the vessel, a rotatable mixing element extendable into the vessel for mixing the contents of the vessel, and a shield; positioning the vessel in the holder; positioning the shield in contact with the vessel to cover the opening of the vessel, the shield when contacting the vessel being unrestrained against upward movement away from the opening; and with the vessel positioned in the holder, using a motor to translate at least one of the mixing element and the holder such that the mixing element passes through the contents of the vessel, the mass of the splash shield preventing separation of the holder and the vessel during translation. - View Dependent Claims (7, 8, 9, 10, 11)
