A container for storing, transporting and intermixing preproportioned substances, comprising in combination: (a) first and second interconnectible sections, said first section including a closed lower end defining a mixing chamber for holding a first admixable substance, and said second section defining a material-containing chamber for communication with said mixing chamber for holding a second admixable substance, the communicating means between said chamber defined by a bore having one end communicating with said mixing chamber and at its other end with said material-containing chamber, said second section having an inner wall substantially free from indentations or protuberances, said bore providing a smooth, uninterrupted continuation of said inner wall of said material-containing chamber, said bore, at said one end, being of lesser diameter than said mixing chamber; (b) partition means in said bore at one end and held in a friction fit by the interior wall of the bore between said chambers and movable between a closing position separating said chambers and a mixing position within said mixing chamber, said partition means sealingly closing said one end of said bore and sized so as to be loosely contained within said mixing chamber; (c) pusher meAns slidably positioned in said material-containing chamber with its inner end slidingly and sealingly engaging said inner wall in a fraction fit, said inner end of said pusher means being slidingly sealingly engageable within said bore, (d) said pusher means being movable along the length of said inner wall and the length of said bore, from an initial position spaced from said other end of said bore, to a final position wherein its said inner wall is sealingly seated in said one end of said bore for positively forcing said partition means into said mixing chamber and clearing the entire second substance from the space through which said inner end moves in going from said pusher means'' initial position to said pusher means'' final position, and for thereafter sealing the upper end of said mixing chamber to allow intermixing in said mixing chamber of the original substances of said chambers by the shaking of said container.

Claim 31

A container for storing, transporting and intermixing preproportioned substances, comprising in combination: (a) first and second interconnectible sections, said first section including a closed lower end defining a mixing chamber for holding a first admixable substance, and said second section defining a material-containing chamber for communication with said mixing chamber for holding a second admixable substance, the communicating means between said chamber defined by a bore having one end communicating with said mixing chamber and at its other end with said material-containing chamber, said second section having an inner wall substantially free from indentations or protuberances, said bore providing a smooth, uninterrupted continuation of said inner wall of said material-containing chamber, said bore, at said one end, being of lesser diameter than said mixing chamber; (b) partition means in said bore at one end and held in a friction fit by the interior wall of the bore between said chambers and movable between a closing position separating said chambers and a mixing position within said mixing chamber, said partition means sealingly closing said one end of said bore and sized so as to be loosely contained within said mixing chamber; (c) pusher meAns slidably positioned in said material-containing chamber with its inner end slidingly and sealingly engaging said inner wall in a fraction fit, said inner end of said pusher means being slidingly sealingly engageable within said bore, (d) said pusher means being movable along the length of said inner wall and the length of said bore, from an initial position spaced from said other end of said bore, to a final position wherein its said inner wall is sealingly seated in said one end of said bore for positively forcing said partition means into said mixing chamber and clearing the entire second substance from the space through which said inner end moves in going from said pusher means'' initial position to said pusher means'' final position, and for thereafter sealing the upper end of said mixing chamber to allow intermixing in said mixing chamber of the original substances of said chambers by the shaking of said container.

Claim 32

The container of claim 18 wherein one said substance is liquid mercury and the other said substance is amalgamable with mercury to form dental restorative material when mixed.

Claim 33

A plural-chamber admixing container for mixing a semi-solid dental restorative material comprising a sectional container body forming a first chamber, one section having a neck bore extending therefrom and open at the end thereof, a movable first plug frictionally removably retained in and closing said neck bore at the entrance of the first chamber, said first plug being smaller than and fully freely movable in tumbling mix-assisting fashion within said first chamber upon removal from said neck bore, a second plug slidably mounted in said neck bores open end and frictionally engaging the wall of said reduced neck bore in externally sealing relation, said second plug being physically separate and spaced at all points from said first plug forming a second chamber peripherally bounded by said neck bore, the effective front surface of said second plug and the effective rear surface of said first plug, and means integral with said second plug and protruding externally from said reduced neck bore for moving said second plug along said neck bore, a first admixable material disposed within said second chamber, a second admixable material disposed within said first chamber for admixing with said material within said second chamber upon dislodgement of said first plug into said first chamber, the inner fact of said second plug being movable substantially to the juncture zone between said neck bore and said first chamber during dislodgement of said first plug to effectively form a single chamber bounded by the walls of said first chamber and the effective inner forward face of said second plug for admixing of said materials after dislodgement of said first plug into said first chamber to form said semi-solid material.

Claim 34

A plural-chamber admixing container for mixing a semi-solid dental restorative material comprising a sectional container body forming a first chamber, one section having a neck bore extending therefrom and open at the end thereof, a movable first plug frictionally removably retained in and closing said neck bore at the entrance of the first chamber, said first plug being smaller than and fully freely movable in tumbling mix-assisting fashion within said first chamber upon removal from said neck bore, a second plug slidably mounted in said neck bores open end and frictionally engaging the wall of said reduced neck bore in externally sealing relation, said second plug being physically separate and spaced at all points from said first plug forming a second chamber peripherally bounded by said neck bore, the effective front surface of said second plug and the effective rear surface of said first plug, and means integral with said second plug and protruding externally from said reduced neck bore for moving said second plug along said neck bore, a first admixable material disposed within said second chamber, a second admixable material disposed within said first chamber for admixing with said material within said second chamber upon dislodgement of said first plug into said first chamber, the inner fact of said second plug being movable substantially to the juncture zone between said neck bore and said first chamber during dislodgement of said first plug to effectively form a single chamber bounded by the walls of said first chamber and the effective inner forward face of said second plug for admixing of said materials after dislodgement of said first plug into said first chamber to form said semi-solid material.
