ABSTRACT:
There is disclosed a dispensing device composed of a can and a nozzle fixedly attachable thereto. The can of the device is generally a container made of sheet metal and having a top wall including an opening and a nozzle made of a synthetic plastics material having a limited inherent flexibility. The nozzle has a wide opening communicating with the equally wide can opening for rapid and convenient filling of the can with material such as a liquid or powder and for equally rapidly discharging the material in the can through the nozzle. The can and the nozzle are separately manufactured by independent and different manufacturing operations and securement of the nozzle to the can is effected by forcing the nozzle with its lower portion into and through the can opening in a manner so that the nozzle is axially retained within the can by means of a circumferential protrusion on the nozzle which is pushed past the top wall rim defining the can opening by utilizing the flexibility of the material of which the nozzle is made. The nozzle is also secured in an angular fixed position relative to the can by serrations on the can which are so disposed that they will bite into the material of the nozzle when and while the nozzle is forced into the can. Such biting of the serrations into the nozzle material occurs automatically in any angular position of the nozzle relative to the can. Locking of the nozzle against rotation relative to the can is required to permit convenient screwing on and off of a closure cap to the nozzle when the device is not in use.
