Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
178 words
A child resistant closure construction for a container, the container having a wall portion, the wall portion having a circular dispensing opening therethrough, the dispensing opening having a removable and reinsertable closure plug normally positioned therein to close the dispensing opening, the closure plug including locking means to normally maintain it in the dispensing opening against casual upward withdrawal, the closure plug carrying a radially extending ear, the closure plug and ear being capable of executing at least limited angular movement about an axis passing through the center of the circular dispensing opening, an abutment carried by the closure member and being located radially outwardly of the periphery of the circular dispensing opening and being in the annular path of at least a portion of the ear upon angular movement of the ear and closure plug, the abutment and the ear being configured to cause the ear to to tilt away from the container interior, whereby the closure plug and/or the ear can be manually grasped and removed to thereby gain access to the contents of the container.
Claim 2
Dependent Claim
178 words
A child resistant closure construction for a container, the container having a wall portion, the wall portion having a circular dispensing opening therethrough, the dispensing opening having a removable and reinsertable closure plug normally positioned therein to close the dispensing opening, the closure plug including locking means to normally maintain it in the dispensing opening against casual upward withdrawal, the closure plug carrying a radially extending ear, the closure plug and ear being capable of executing at least limited angular movement about an axis passing through the center of the circular dispensing opening, an abutment carried by the closure member and being located radially outwardly of the periphery of the circular dispensing opening and being in the annular path of at least a portion of the ear upon angular movement of the ear and closure plug, the abutment and the ear being configured to cause the ear to to tilt away from the container interior, whereby the closure plug and/or the ear can be manually grasped and removed to thereby gain access to the contents of the container.
