Abstract
This invention pertains to a sprayer for insecticides. The sprayer consists of a tank and a cover assembly which includes an air pump for pressurizing the tank. The tank has a funnel-shaped neck which is engaged by the cover to form an air-tight enclosure. In order to insure that the cover does not separate suddenly when it is opened while the tank is still pressurized, the neck is provided with extrusions which do not permit the closure to separate from the tank as air is bleeding out of the tank.
