Abstract: A disposable spray dispensing assembly for liquid materials includes a container comprising an aerosol can, and a spray head initially detached from the container. A cap closes an opening of the can and has a coined cover portion which may be ruptured by impact force to present a hole for reception of a dip tube of the spray head. A resilient, deflectable leg has a groove which locks with the cap when the dip tube is inserted into the container, and thereby provides a non-releasable coupling to secure the spray head to the container in captive fashion.
