An apparatus and package for liquid or granular materials includes two pivotally mounted dispensing blocks associated with a dispensing arm, whereby upon application of an actuating force to the dispensing arm, a resilient tube of the package is pinched shut by one dispensing block and the other dispensing block opens a slit diaphragm valve disposed within the resilient tube.

A portable chemical spraying apparatus has an electric motor/compressor mounted inside of two halves of a lightweight housing. A compressed air output of the motor/compressor connects directly to a compression chamber. Compressed air inside of the compression chamber moves through the venturi of a nozzle into a mixing chamber. The mixing chamber opens to atmosphere through a vortex of compressed air received via spiral passages connecting to the compression chamber. Chemicals may be drawn into the mixing chamber through a needle, which may perforate a seal of a disposable chemical container at the time the chemical container is connected to the portable spraying apparatus. Simultaneously, the needle seals with a metered conduit which extends to the inside bottom of the chemical container.

A viscous liquid dispenser is characterized by a yieldable lever arm pivotally connected within a casing. The lever arm carries a rigid dispensing block thereon. In response to the imposition of an actuating force to the lever arm, the arm pivots to bring the tip of the dispensing block into contact with a resilient flexible tube extending from a viscous liquid reservoir. The resilient tube is constricted between the tip of the dispensing block and a predetermined impact point located on a movable back-up block provided adjacent to the resilient tube and opposite from the dispensing block. The lever arm yieldably responds to the continued application of an actuating force to compress a portion of the resilient tube immediately below the constriction between the dispensing block and a predetermined dispensing surface disposed on the back-up block. The compressive force thereby imparted to the entrapped viscous liquid unseats a spring-biased long-throw ball check valve and to expel a predetermined quantity of viscous liquid from the resilient tube. Upon cessation of the actuating force, the yieldable lever arm and the resilient tube return to their unstressed states, and the ball check valve returns to its seat, the suction created thereby draws any remaining viscous liquid back into the lower portion of the resilient tube. The magnitude of the volume of viscous liquid dispensed by each actuation of the yieldable lever arm is able to be regulated by moving the back-up block with respect to the dispensing block.
