Dual chambered mixing and dispensing vial

Claim 2

A dual chamber mixture dispensing device comprising: first and second chambers separated from each other by a common wall having an orifice between said two compartments; a plugging means for selectively sealing said orifice; a depressible stem situated within said second chamber for dislodging said plugging means from said orifice; and a means for dispensing a mixture from said device comprising a droplet nozzle on said first chamber.

Claim 3

The dispensing device of claim 1, wherein the cross-sectional area of the depressible stem is less that the cross-sectional area of said orifice.

Claim 4

The dispensing device of claim 1, wherein the walls of the second chamber are selectively depressible toward first chamber to actuate the depressible stem to dislodge the plugging means.

Claim 5

The despensing device of claim 3 wherein the walls of the second chamber define a plurality of flexible bellows depressible toward said first chamber.

Claim 6

The dispensing device of claim 3, wherein the walls of the second chamber define a flexible bell-shaped base depressible toward said first chamber.

Claim 7

The dispensing device of claim 3, further comprising a removeable base cap means securely fitable over said second compartment to prevent non-intentional depression of said walls.

Claim 8

A dual chamber mixture dispensing device for selectively maintaining mixture components separate until mixing and dispensing is desired, comprising A. a mixture dispensing means comprising a droplet nozzle; B. a first chamber carrying the mixture dispensing means for storing one or more of the mixture components, having substantially rigid walls, one of said walls being a common wall to a second chamber, said common wall having an orifice open to said second chamber; C. a second chamber for storing one or more of the mixture components adjacent to said first chamber extending from said common wall, the other walls and base to said second chamber being selectively depressible toward said first chamber; D. a plugging means for selectively sealing said orifice having a first position sealing said orifice and a second position dislodged from said orifice; and E. a depressible stem located within said second chamber when said plugging means is in its first position and situated proximately between said plugging means and said flexible base of said second chamber so that depression of said base walls toward the first chamber will cause the depressible flexible stem to dislodge said plugging means from said orifice permitting commingling of the mixture components.

Claim 9

A dual chamber mixture dispensing device for selectively maintaining mixture components separate until mixing and dispensing is desired, comprising A. a mixture dispensing means comprising a droplet nozzle; B. a first chamber carrying the mixture dispensing means for storing one or more of the mixture components, having substantially rigid walls, one of said walls being a common wall to a second chamber, said common wall having an orifice open to said second chamber; C. a second chamber for storing one or more of the mixture components adjacent to said first chamber extending from said common wall, the other walls and base to said second chamber being selectively depressible toward said first chamber; D. a plugging means for selectively sealing said orifice having a first position sealing said orifice and a second position dislodged from said orifice; and E. a depressible stem located within said second chamber when said plugging means is in its first position and situated proximately between said plugging means and said flexible base of said second chamber so that depression of said base walls toward the first chamber will cause the depressible flexible stem to dislodge said plugging means from said orifice permitting commingling of the mixture components.
