Abstract: A method of cleaning a drain by opening a container within a dispenser and dispensing drain cleaner from the container, through an outlet of the dispenser, and into the drain. The dispenser may have an upwardly extending pin for opening the container. Alternatively, the dispenser may have a cutter for opening an angled end of the container. In another alternative, the container may include a plug and a cooperating stem for opening the bottom of the container.

Abstract: A dispensing closure for a squeeze container comprises a closure cap having a discharge spout terminating in a discharge orifice, and a spout cover hingedly connected to the cap for manual rocking movement about a transverse hinge axis between discharge orifice closed and open positions. The cover has a lid overlying and sealing the orifice closed and is snap locked thereto in the closed position.

Abstract: A child resistant closure construction for one end of a container, such as a cylindrical container. A removable plug normally closes a dispensing opening at one end of the container, the plug provided with a radially extending ear. The plug and ear are so configured that removal of the plug by a child is difficult because there is no easy method to firmly manually grasp any portion of the plug. A raised abutment is integrally carried by the end closure of the container. Upon rotation of the closure plug to a certain angular position, the ear strikes the abutment and the ear tilts away from the container interior to thereby enable it to be grasped and pulled to remove the closure plug.

Abstract: A child-resistant closure comprising a can ring provided with an orifice through which the container is filled or emptied, the orifice having a peripheral rim in the form of an inverted U-shaped channel defined by an exterior leg and an interior leg, a portion of the interior leg extending below the lower edge of said interior leg to provide an unlocking tab, said can ring being further provided with indicia in its top surface to designate the location of said unlocking tab, and a cap, the cap comprising a disc portion; an annular ring portion disposed in a plane parallel to said disc portion, said annular ring portion having a peripheral sealing skirt; an annular wall connecting the disc portion and the annular ring portion, the annular wall forming with the sealing skirt an arcuate annular groove on the underside of the annular ring portion, the annular groove being adapted for flush superposition on the inverted U-shaped channel; a pull tab extending outwardly horizontally from the periphery of the annular
