Abstract

A closure assembly for use on a container neck finish has an inner cap which threadedly engages the neck finish and an outer cap which is received by the inner cap. Torque lugs on the outer cap cooperate with abutment formations on the inner cap such that rotation of the outer cap drives the inner cap onto the neck finish. Cooperative engagement between the two caps is achieved by downward axial movement of the outer cap. An arrangement of ramp sections on the inner cap and an arrangement of interior lugs on the outer cap provide an assist feature helping to pull the outer cap in the axially downward direction. Another feature of the closure assembly includes a spring-biasing relationship between the inner and outer caps. The inner cap also includes an abutment structure which cooperates with the container to limit drop test deformation of the container.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation of PCT Application No. PCT / US2014 / 063816, filed Nov. 4, 2014 which claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 905,488 filed Nov. 18, 2013, both of which are hereby incorporated by reference.BACKGROUND

[0002] One construction for a child-resistant (CR) closure is to use a combination of an inner cap and a cooperating outer cap. When the neck finish of the corresponding container is externally threaded, the inner cap is typically constructed and arranged with internal threads which allow the inner cap to be securely assembled, by threading, onto the neck finish. Although other connection constructions between the inner cap and the container neck finish might be contemplated, the exemplary embodiment disclosed herein shows a threaded connection.

[0003] In order to incorporate a child-resistant feature or capability to this inner and outer cap construction, an engagement between these t...
