Abstract
Abstract A child resistant package comprising an open-mouth container having a plurality of circumferentially spaced projections extending radially outwardly adjacent the open end thereof, each projection defines a notch facing downwardly, and a closure having a top panel and an annular skirt depending from the periphery of the top panel, and a plurality of radially inwardly extending and circumferentially spaced locking lugs on the inner surface of the skirt. The locking lugs are adapted to engage the notches in the projections on the container. A tamper-indicating member comprises an annular ring having portions extending between the lower edge of the skirt of the closure and a portion of the container and operable to normally limit axial movement of the closure. The ring offers a visual indication that the contents have not been tampered with and the ring must be removed before the closure can be removed. The container includes a specially designed inclined surface provided with dual slopes. One slope extends radially outwardly in a circumferential direction and the other slope extends downwardly and radially inwardly and terminates in a locking notch. The closure can be applied to the container when the tamper-indicating member is in position through rotation of the closure causing the cam lugs on the closure to engage the inclined surface and flex the skirt of the closure outwardly to thereby direct the cam lugs into engagement with the locking notch.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
224 words
A child resistant package comprising an open-mouth container having a body with a circumferentially spaced projection extending radially outwardly adjacent the open end thereof, said projection having a downwardly facing locking notch, a closure having a top panel and an annular skirt depending from the periphery of the top panel, a plurality of radially inwardly extending and circumferentially spaced locking lugs on the inner surface of said skirt, said locking lugs being adapted to engage the shoulder in the projection on the container, means yieldingly urging the closure upwardly to cause a lug to remain in engagement with said notch when the closure is on the container, a tamper-indicating member comprising an annular ring having portions extending between the lower edge of the skirt of the closure and a portion of the container and operable to normally limit axial movement of the closure, said container including a surface extending from the body of the container to a position adjacent the notch and being downwardly and outwardly inclined such that the closure can be applied to the container when the tamper-indicating member is in position through rotation of the closure causing a cam lug on the closure to engage and move on the inclined surface and flex the skirt of the closure outwardly to thereby direct the cam lug into engagement with the locking notch.
Claim 2
Dependent Claim
224 words
