Abstract
Abstract A child resistant package comprising a container and a closure. The container has an open end, a thread on the inner surface of the open end, diametrically opposed lugs on the outer surface of the open end having a radially extending surface. The closure has a top wall, a peripheral skirt and an annular wall spaced radially inwardly from the peripheral skirt, and having an external thread on the outer surface thereof interengaging the thread on the inner surface of the upper end of the closure. The skirt has radially engageable lugs extending radially inwardly from the skirt. The skirt is flexible such that the closure can be engaged with the container by interengagement of the threads and rotation of the closure in one direction until the lugs on the skirt engage the lugs on the container and the closure may be removed by radially compressing portions of the closure at about 90° between the lugs on the closure to disengage the lugs on the closure from the lugs on the container such that the closure can be removed by rotation relative to the container in the opposite direction.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
153 words
A child resistant package comprising a container having an open end, a thread on the inner surface of the open end, a closure having a top wall, a peripheral skirt, an annular wall spaced radially inwardly from the peripheral skirt, said annular wall having an external thread on the outer surface thereof interengaging the thread on the inner surface of the upper end of the closure, said skirt and said closure having radially engageable means, said skirt being flexible such that the closure can be engaged with the container by interengagement of the threads and rotation of the closure in one direction until the radially engageable means engage and the closure may be removed by radially compressing portions of the closure at about 90° between the lugs on the closure to disengage the radially engageable means such that the closure can be removed by rotation relative to the container in the opposite direction.
Claim 2
Dependent Claim
153 words
A child resistant package comprising a container having an open end, a thread on the inner surface of the open end, a closure having a top wall, a peripheral skirt, an annular wall spaced radially inwardly from the peripheral skirt, said annular wall having an external thread on the outer surface thereof interengaging the thread on the inner surface of the upper end of the closure, said skirt and said closure having radially engageable means, said skirt being flexible such that the closure can be engaged with the container by interengagement of the threads and rotation of the closure in one direction until the radially engageable means engage and the closure may be removed by radially compressing portions of the closure at about 90° between the lugs on the closure to disengage the radially engageable means such that the closure can be removed by rotation relative to the container in the opposite direction.
