Abstract
Abstract A mixing bag and method is provided for mixing ingredients and dispensing the mixed ingredients. The bottom of the bag has a converging tip. The top edge of the bag defines an open end and includes a reciprocally shaped edge to the bottom edge so that the bags can be cut from a continuous tube of material. The bag is filled with ingredients to be mixed through the open end and the ingredients are mixed by kneading the bag with the hands. The bag is closed prior to mixing. Once the ingredients are sufficiently mixed, the converging tip of the bag is removed and the contents are squeezed out from the bag. Prior to mixing, a closure device, or a twist applied to the bag, closes off the open end of the bag. Particular materials to be mixed are dental alginates and stones for making dental impressions. Other ingredients besides dental products can be mixed in the bag.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
171 words
A mixing bag arrangement for mixing ingredients comprising: first and second panels each having an outer peripheral edge; the first panel interconnected to the second panel along a first portion of each outer peripheral edge of each of the first and second panels to define an enclosed chamber for receiving the ingredients; the enclosed chamber accessible through an open end defined by a second portion of each outer peripheral edge which is not interconnected to one another; the first portion of each peripheral edge including a region defining a converging tip disposed on an opposite end of the panel arrangement relative to the open end; and the first and second panels each including a line of perforations extending across the converging tip of each of the first and second panels permitting a dispensing opening to be formed therein when the line of perforations is torn, to dispense the ingredients from the enclosed chamber, the line of perforations extending across both of the first and second panels which define the enclosed chamber.
Claim 2
Dependent Claim
171 words
A mixing bag arrangement for mixing ingredients comprising: first and second panels each having an outer peripheral edge; the first panel interconnected to the second panel along a first portion of each outer peripheral edge of each of the first and second panels to define an enclosed chamber for receiving the ingredients; the enclosed chamber accessible through an open end defined by a second portion of each outer peripheral edge which is not interconnected to one another; the first portion of each peripheral edge including a region defining a converging tip disposed on an opposite end of the panel arrangement relative to the open end; and the first and second panels each including a line of perforations extending across the converging tip of each of the first and second panels permitting a dispensing opening to be formed therein when the line of perforations is torn, to dispense the ingredients from the enclosed chamber, the line of perforations extending across both of the first and second panels which define the enclosed chamber.
Claim 3
Dependent Claim
38 words

Claim 10
Dependent Claim
36 words
The mixing bag arrangement of claim 8, wherein the perforations spaced apart from the line of perforations includes two lines of perforations offset from one another in a direction parallel to the two lines of perforations.
Claim 11
Dependent Claim
28 words
The mixing bag arrangement of claim 6, further comprising closure means for closing the enclosed chamber from the top edge of each of the first and second panels.
Claim 12
Dependent Claim
42 words
