Abstract
Abstract The embodiment of the invention disclosed herein is directed to a combination lock safety cap for containers that are particularly designated for receiving materials such as drugs or chemicals which are detrimental to human life, and which drugs and chemicals are to be prevented from getting into the hands of small children. The combination lock safety cap is of a particular arrangement as to allow only the particular person knowing the arrangement or combination of the components of the safety cap to open the container which utilizes such caps. The container which receives the combination cap of this invention includes a neck portion formed on the container to function as an access opening for filling and removing material from the container. Radially outwardly directed tab means is formed about the exterior periphery of the neck portion, said tab means generally including four quadrant located, discrete tabs about the neck portion. A closure assembly is fashioned to fit over the neck portion and includes a plurality of rotatable lock rings held in position between a cap and retaining ring so as to freely rotate within the cap. Each of the locking rings is located radially inwardly of an integral peripheral depending flange portion associated with the cap and includes an outwardly directed tab which fits through a slot formed in the flange portion. When all of the radially outwardly directed tab portions of the locking rings are placed in alignment, or placed in predetermined locations with respect to indicia formed about the cap, a corresponding plurality of notches are aligned and placed in registry with the radially outwardly directed tabs of the neck portion to allow the closure structure to be lifted and removed from the container.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
349 words
A container closure structure and container used in conjunction therewith, comprising: a container for receiving a given quantity of material to be restRicted from use by small children; a neck portion formed on said container to function as an access opening for filling said container and for removing said material therethrough; radially outwardly directed tab means formed about the exterior periphery of said neck portion; a closure assembly fashioned firmly to fit said neck portion to seal the container and prevent said material from being removed from said container, said closure assembly including; a cap to fit over said neck portion and form a seal about the mouth of said neck portion; an integral peripheral depending flange portion associated with said cap, said integral peripheral depending flange portion having a dimension and configuration freely to fit over said radially outwardly directed tab means of said neck portion; a retainer means formed about the inner peripheral portion of said integral peripheral depending flange portion, said retainer means extending inwardly a distance to underly said tab means of said neck portion when said closure assembly is in position on said container; first notch means formed on said retaining means, said first notch means being sized and configurated to accept said tab means when said closure assembly is positioned over said neck portion; locking means associated with said closure assembly, said locking means being movably secured between said cap and said retaining means; second notch means formed in said locking means, said second notch means being sized and configurated to accept tab means when said closure assembly is positioned over said neck portion; and positioning means associated with said locking means to enable manual relative movement of said locking means with respect to said retaining means and said cap means, to allow alignment of said first and second notch means of said retaining means and said locking means, respectively, for easy application and removal of said closure assembly from said neck portion, whereby misalignment of said first and second notch means prevents inadvertent removal of said closure assembly from said neck portion.
Claim 2
Dependent Claim
349 words
A container closure structure and container used in conjunction therewith, comprising: a container for receiving a given quantity of material to be restRicted from use by small children; a neck portion formed on said container to function as an access opening for filling said container and for removing said material therethrough; radially outwardly directed tab means formed about the exterior periphery of said neck portion; a closure assembly fashioned firmly to fit said neck portion to seal the container and prevent said material from being removed from said container, said closure assembly including; a cap to fit over said neck portion and form a seal about the mouth of said neck portion; an integral peripheral depending flange portion associated with said cap, said integral peripheral depending flange portion having a dimension and configuration freely to fit over said radially outwardly directed tab means of said neck portion; a retainer means formed about the inner peripheral portion of said integral peripheral depending flange portion, said retainer means extending inwardly a distance to underly said tab means of said neck portion when said closure assembly is in position on said container; first notch means formed on said retaining means, said first notch means being sized and configurated to accept said tab means when said closure assembly is positioned over said neck portion; locking means associated with said closure assembly, said locking means being movably secured between said cap and said retaining means; second notch means formed in said locking means, said second notch means being sized and configurated to accept tab means when said closure assembly is positioned over said neck portion; and positioning means associated with said locking means to enable manual relative movement of said locking means with respect to said retaining means and said cap means, to allow alignment of said first and second notch means of said retaining means and said locking means, respectively, for easy application and removal of said closure assembly from said neck portion, whereby misalignment of said first and second notch means prevents inadvertent removal of said closure assembly from said neck portion.
Claim 3
Dependent Claim
43 words
In the container closure structure and container as set forth in claim 1 wherein said radially outwardly directed tab means formed about the exterior periphery of said neck portion are located at a given distance below the mouth opening of said neck portion.
Claim 4
Dependent Claim
49 words
In the container closure structure and container as set forth in claim 2 wherein said radially outwardly directed tab means includes a plurality of discrete tabs extending radially outwardly of said neck portion, each of said discrete tabs having an extent different than other ones of said discrete tabs.
Claim 5
Dependent Claim
33 words
In the container closure structure and container as set forth in claim 3, wherein said plurality of discrete tabs are four in number and each located substantially at right angles to one another.
Claim 6
Dependent Claim
81 words
In the container closure structure and container as set forth in claim 4 wherein said neck portion formed on said container is round in configuration, said radially outwardly directed tab means being formed at different quadrant locations about said round neck portion, and wherein said cap is round in configuration and said locking means includes locking ring means associated therewith rotatably to move within said cap to align its associated notch means with said tabs for removal of said closure structure.
Claim 7
Dependent Claim
68 words
In the container closure structure and container as set forth in claim 1 wherein said locking means includes a rotatably secured locking ring means positioned between said cap and said retaining flange, said retaining flange being circular in configuration to fit about a circular configurated neck portion, and wherein said locking means is rotated to align said notch means with said tabs for removal of the closure structure.
Claim 8
Dependent Claim
52 words
In the container closure structure and container as set forth in claim 6 wherein said locking ring means includes a plurality of independent axially displaced locking rings, each oF said locking rings including notches to be aligned with said tab means to facilitate removal of said closure structure from said neck portion.
Claim 9
