Abstract: A dispenser closure is provided having an upper wall portion with at least one opening therein and having a thread depending from an inner annular surface thereof. A lower wall portion of the closure has at least two lugs depending from a lower inner annular surface thereof having a configuration and size to cooperate with at least one stop lock depending from a container neck and at least one of the cooperating closure lugs does not cooperate with the cooperating stop lock when the lower wall portion is deformed by a squeezing force.

Abstract: A closure for use on a container having an externally threaded neck is disclosed wherein an inner surface of a downwardly depending skirt portion of the closure cap includes a helical thread having a flat upper surface with a lower thread profile having a first depth greater than an upper thread profile of a second depth. The helical thread of the closure tapers into the sidewalk of the closure skirt. The closure is provided with a seal integral with the inner surface of the skirt, spaced from a top wall of the closure, and retained at a lowermost point along the downwardly depending skirt by a bead.

Abstract: A bottle having a modified neck and intended for use with a child-resistant closure which allows the user to open the bottle without removing the closure completely from the bottle is described. The neck includes at least one locking lug and at least one anti-removal ring. The anti-removal ring is positioned between the lug and the open end of the neck. The neck may further include at least one deformation recess, with the deformation recess being adjacent to and radially offset from the locking lug. The ring and recess are intended to deter the user from bypassing the child-resistant safety features of the bottle and removing the closure completely from the bottle.

Abstract: A child-resistant closure and dispensing container package in which the measuring cup has a second, exterior annular wall forming threads engageable with threads on the neck of a container and child-resistant lock means at a lower portion of the wall engageable with complementary lock means on the container in a locked position to prevent unthreading of the closure from the container until the annular wall is deflected to move the complementary lock means out of engagement with each other to permit rotation of the closure in an unthreading direction. Also a seal is provided to prevent leakage during unthreading movement of the closure between fully closed and a locked position of the closure.
