Claim 0:
1. An ergonomic friendly non-aspirating dispenser for ejecting a thixotropic gel, consisting of:
a dispenser, said dispenser having walls forming a container consisting of a single opening,
a valve sealing the single opening of the container,
a flexible bag positioned inside the container and having an initial bag volume inside the bag that is in communication with and operatively connected to the valve,
wherein the container has an internal volume consisting of the initial bag volume within the flexible bag and a non-bag volume located between said dispenser walls and outer surface of said flexible bag,
a thixotropic gel located in the flexible bag and having a viscosity of from about 100 to about 1,500 centipoises,
wherein the non-bag volume consists of a gas having an initial pressure of about 25 to about 50 psi,
wherein the initial bag volume is from about 65% to about 90% of the container internal volume,
wherein said non-bag volume is free of a propellant, a volatilizable liquid, or a foam forming gas, or any combination thereof,
wherein an actuator is operatively connected to said valve, said actuator upon activation thereof being capable of opening said valve so that the gas exerting pressure on said flexible bag will force said thixotropic gel out of the flexible bag and said dispenser container in the form of non-aspirated droplets having a mean volume diameter from about 150 to about 500 microns, and
wherein the dispenser is free of an aspirator.
