Abstract
Abstract The present invention involves a container and cap which is generally childproof and may be rendered non-childproof permanently. The invention involves a container having a cylindrical neck at the top and threads molded about the exterior of the neck as well as an inner cap and outer cap. The inner cap has a top and cylindrical side wall with threads molded on the inside of the side wall so as to mate with the threads of the container. The top or side of the inner cap has ratchet type segments on its outside and the outer cap has ratchet type segments on the inside of its top or side. The outer cap has a cylindrical side wall and is usually freely rotatable about the inner cap so as to be childproof. When in the childproof configuration as described, downward pressure is required by the user so as to engage the two rachet type segments and thereby engage the two caps to permit opening. Further, the outer cap has an opening in its side wall at a level near the bottom of the side wall of the inner cap and also has integrally attached thereto a flexible connector and stop. The flexible connector and stop are located so as to permit insertion of the stop into the opening so as to extend beyond the opening and push up the inner cap so as to permanently lock it into a position wherein the inner cap and outer cap ratchet type segments are permanently engaged. This renders the cap permanently non-childproof.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
293 words
A container and a cap therefor which is generally childproof, which comprises: (a) a container having a cylindrical neck at the top and threads molded about the exterior of said neck; (b) an inner cap having a top and a cylindrical sidewall, having threads molded about the interior of said sidewall to interlock or mate with the threads of said container, said inner cap having ratchet type segments located on its exterior; and (c) an outer cap having a top and a cylindrical sidewall, said top having ratchet type segments located on its interior so as to be engageable with the ratchet type segments of said inner cap, said outer cap being of a sidewall height greater than the inner caps, said outer cap being located and fitted loosely about the inner cap, said outer cap having an opening in said sidewall at a level near the bottom of the sidewall of said inner cap, said outer cap also having integrally attached thereto a flexible connector and a stop located so as to permit the stop to be inserted into said opening and push up said inner cap to lock it into a position wherein the inner cap and outer cap ratchet type segments are engaged and the outer cap can no longer be freely rotatable about the inner cap, thus, (i) being a childproof container and cap when said stop is not inserted due to the free rotation of the outer cap about the inner cap except when the outer cap is pushed down onto the inner cap and simultaneously rotated; and, (ii) being a non-childproof container and cap when the stop is inserted into the opening to lock the inner cap and outer cap into a ratchet type segment engaged position.
Claim 2
Dependent Claim
293 words
A container and a cap therefor which is generally childproof, which comprises: (a) a container having a cylindrical neck at the top and threads molded about the exterior of said neck; (b) an inner cap having a top and a cylindrical sidewall, having threads molded about the interior of said sidewall to interlock or mate with the threads of said container, said inner cap having ratchet type segments located on its exterior; and (c) an outer cap having a top and a cylindrical sidewall, said top having ratchet type segments located on its interior so as to be engageable with the ratchet type segments of said inner cap, said outer cap being of a sidewall height greater than the inner caps, said outer cap being located and fitted loosely about the inner cap, said outer cap having an opening in said sidewall at a level near the bottom of the sidewall of said inner cap, said outer cap also having integrally attached thereto a flexible connector and a stop located so as to permit the stop to be inserted into said opening and push up said inner cap to lock it into a position wherein the inner cap and outer cap ratchet type segments are engaged and the outer cap can no longer be freely rotatable about the inner cap, thus, (i) being a childproof container and cap when said stop is not inserted due to the free rotation of the outer cap about the inner cap except when the outer cap is pushed down onto the inner cap and simultaneously rotated; and, (ii) being a non-childproof container and cap when the stop is inserted into the opening to lock the inner cap and outer cap into a ratchet type segment engaged position.
Claim 3
Dependent Claim
93 words
The container and cap of claim 1 wherein said flexible connection is a flap which is removably insertable into the exterior of the top of the outer cap and is attached to the cap at the edge of the top and has a peg for a stop at the end opposite from which the flap is attached, said flap being of a predetermined length so that when it is rotated outwardly about 270°, the peg is insertable into the opening of the outer cap to lock the inner cap and outer cap together.
Claim 4
Dependent Claim
30 words
The container and cap of claim 2 wherein said peg is cylindrical with an enlarged diameter cone at its insertable end so that it may not be removed after insertion.
Claim 5
Dependent Claim
32 words
The container and cap of claim 1 wherein said stop has the configuration of an arrow and the arrowhead is of significant size so that it may not be removed after insertion.
Claim 6
Dependent Claim
24 words
The container and cap of claim 1 wherein said flexible connector is a strip of plastic which is tearably removable from said outer cap.
Claim 7
Dependent Claim
