Description
1 160r~9G
This invention relates to the provision of a closure cap for a container and to a container and closure cap assembly.
Children often attempt to tamper with containers of pills and the lilce and try to open such containers to get at the contents. Some-times children have succeeded in opening a container of pills with tragic results.
It is, therefore, an object of an aspect of the present inven-tion to provide a container closure cap that is not easy to open simply by upward pressure.
According to one aspect of the present invention, a closure cap is provided which is adapted for closing the mouth of a container, the cap comprising an inner member including a plug and an outer member including a depending skirt, wherein, when the cap is in operative posi-tioin on the container, the inner member is coaxia!ly disposed within the upper part of the outer member, the plug being seated so as to close the mouth of the container with the top of the inner member flush with or below the top of the outer member, the upper part of the outer member being positioned above the mouth of the container, and the skirt of the outer member being positioned so as to embrace and enga8e with the outer surface of the container around the mouth.
By one variant thereof, the inner member can be removed without damaging the closure cap only when it has been turned into a predeter-mined position relative to the outer member.
By another variant thereof, the outer member has a cut-out in its upper peripheral edge, and a substantially annular internal bead engaging with an annular external recess in the inner member, the internal bead being interrupted below or in the region of the cut-out, and the inner member has a thumb grip adjacent to its upper edge and is ~
1 16~)596 rotationally adjustable within the outer member.
By still another variant thereof, the cap is molded as an integral unit with the inner member disposed coaxially above the outer member, the two parts being interconnected by a frangible connection which is broken when the closure cap is applied to a container.
Preferably, as an additional safety factor in another variant of this invention, the inner member is shaped to engage with the outer member so that the inner member is positively held in position.
Alternatively, by another aspect of this invention, the closure cap may be molded in two parts, an inner member and an outer member which may be formed simultaneously but separately in the same mold, after which an assembly opcration is carried out so that complete closure caps are discharged from the molding machine.
Other methods may, if desired, be used. For example, with less soph;sticated molds according to another aspect of this invention, the two parts of the closure cap may be molded separately and may then be assembled by hand or by a suitable form of press tool or assembly machine.
By another aspect of this invention, a closure cap is provided for closing the mouth of a container, the closure cap comprising: (a) an inner member including a plug with an external annular recess; (b) an outer member including a depending skirt and having a gap or cut-out in its upper peripheral edge and a substantially annular internal bead to engage with the external annular recess in the inner member, the top of the outer member being flush with or above the top of the inner member;
(c) an interruption in the substantially annular internal bead on the outer member forming an opening below the gap or cut-out in the peripheral ````'':,! edge of the outer member; (d) a thumb grip on the inner mernber normally l 18~59~ -masked by the outer member and adapted to be moved into operative posi-- tion adjacent to the gap or cut-out by rotation of the inner member; and (e) a web or webs connecting the inner member to the outer member and further wherein, when the closure cap is in operative position on a con- -- tainer, the inner member is coaxially disposed within an upper part of the outer member with the plug sealed in or over the mouth of the con-tainer so as to close the mouth, the upper part of the outer member is positioned above the mouth of the container and the skirt of the outer Inember is positioned so as to embrace and engage with the outer surface of the container around the mouth.
By a variant of this aspect of the invention, the inner member is connected by a frangible connection to the outer member, the closure cap being applied to the container, which has an open mouth, by downward pressure so that the outer member is secured around the mouth of the con-tainer in the manner of a sleeve, and the inner member is pressed into the outer member so as to seat in or on the mouth of the container by movement re]ative to the outer member, so that the rrangib]e connection is broken by the act of applying the closure Cclp to tlle container.
By another aspect of this invention, a cont.ainer closure cap is provided whi.ch is formed as an i.ntegral uni.t with an inn~r part dis-posed co-axially above an outer part, the two parts being i.nterconnected by a frangible connection which is bro~en when the closure cap is applied to the container, breaking being effected by downward movement of the inner part into the outer part to an operative position in which the inner part is rotatable within the outer part, the arrangement being such that when in the operative position the closure cap is retained on the con-: ~ !
~--~ tainer by the outer part embracing an outer surface of the container in _ ~
l 1~0~6 the manner of a~sleeve w~ile the inner part covers the top of the container and can be removed only when it has been turned into a predetermined position relatively to the outer part to provide a child-resistant feature for the closure cap.
By a variant thereof, the frangible connection is a substantial-ly annular diaphra~n.
By another variant the outer part which is adapted to fit over the outside of the container has an annular internal recess to receive an annular projection on the outside of the container.
By still another variant, the inner part has an outer recess and the outer part has a corresponding inner projection.
By yet another aspect of this invention, a container closure cap is provided comprisiny an inner part connected by a frangible connec-tion to an outer part, the closure cap being applied to the contai.ner, which has an open mouth, by downward pressure so that the outer part is secured around the mouth of the container in the manner of a sleeve and the inner part is pressed into the outer part so as to seat in or on the mouth of the container by movement relatively to the outer part so that the frangible connection between the two parts is bro~en by the act of applying the cl.osure cap to the container, the arrangement being such that the inner part can be removed only when it has been turned into a prede- j tennined position relatively to the outer part to provide a child resis- ¦
tant feature for the closure.cap.
By a variant of the above described aspects and variants the child-resistant feature is formed by providing the outer part with a gap a r~ ' or cut out in its upper peripheral edge and the inner part with a thumb grip, the inner part being anqularly adjustable within the outer part so - 3a -5 9 ~
- that the thumb grip may be moved into registration with the gap or cutout . _ - when it is desired to remove the inner part from the outer part to open the container.
By another variant of the above described aspects and variants, the container closure cap is moulded as an integral unit and adapted for ~ -conversion into two separate parts on application to the container.
By another aspect of this invention, a container closure cap is provided which is moulded as a single integral unit comprising an inner part disposed coaxially above an outer part and frangible means connecting the inner part to the outer part so that relative angular movement of the two parts is prevented, the closure cap being applied to the container, which has an opening through which the contents of the container can be dispensed, by downward pressure so that the outer part of the closure cap forms a sleeve around part of the container and the inner part of the closure cap is moved into the outer part to cover the opening in the con-tainer, the frangible connection being bro~en when the closure cap is applied to the container by the downward movement of the inner part into the outer part to convert the closure cap into two separate parts with the inner part rotatable within the outer part and child-resistant means to inhibit removal of the inner part from the outer part until the inner part has been turned into a predetermined position relatively to the outer part.
Of a variant of the above described aspects and variants, the - container closure cap includes a tamper-proof feature comprising a web connecting the top of the inner part to the outer part.
In the accompanying drawings, Figure 1 shows a sectional view of one embodiment of a closure -~' - 3b -l 160596 cap in accordance with an aspect of this invention with the two parts of the closure cap formed separately;

Figures 6 and 7 are detail views and Figure 8 is a modification of other aspects of this invention.
Referring to the drawings, 1 is a container which as a smooth inner surface 2 and an outer annular projecting ring 3. A two-part closure cap comprises an inner member 4 in the form of a plug and an outer member 5 in the form of a sleeve, the inner member 4 being disposed coaxially within the outer member 5. The outer member 5 has an internal annular recess 7 shaped to receive the annular projecting ring 3, the shape of the recess 7 and the ring 5 being such that it is relatively simple to push the outer member 5 downwardly over the ring 3 so that the ring 3 engages in the recess 7 but it is almost impossible to remove the member 5 again by a simple upward movement. The outer member 5 has an internal substantially annular bead 8 for engagement within an annular recess 9 in the outer surface of the inner member 4 and the outer member 5 also has an interruption 13 in the bead 8 forming a gap therein as 1 lB05~6 indicated in Figure 7. The inner member 4 has a thumb grip 11 an~ an embossed arrow or other mark on the top to indicate the position of the thumb grip 11. The interruption 13 in the substantially annular bead 8 is directly below or in the region of a gap or cut-out 10 in the peripheral top edge of the outer member 5 so that when upward pressure is applied to the thumb grip 11 of the inner member 4 through the gap or cut-out 10, the inner member 4 may be removed or pushed out of the outer membPr 5 in a tilting movement. It will be understood that pressure can be applied to the thumb grip 11 only when the inner member 4 is manipulated to bring the thumb grip 11 into registration with the gap or cut-out 10.
When upward pressure is applied to the thumb grip 11 to push the inner member 4 out of the outer member 5 to open the container 1, the inner member 4 first tilts because upward pressure on the thumb grip raises the near side of the inner member 4 so that the top of the inner member 4 inclines downwardly away from the gap or cut-out 10. In the opening movement, therefdre, the inner member 4 may be described as being flicked out of the outer member 5.
The assembly of the parts of the closure cap may be effected in such a way that the thumb grip 11 is out of registration with the gap or cut-out 10 in the periphery of the outer member 5 so that if the closure cap be applied automatically to a container, i.e., by machine, the closure cap will be seated on the container in a child-resistant position.
Then, in operation, to open the container a user moves the inner member 4 angularly relative to the outer member 5 until the thumb grip registers with the gap or cut-out 10 and then flicks out the inner member. To facilitate correct positioning of the inner member for openin~, the arrow or other indication referred to above may be provided on the top of the inner member, the inner member being pushed angularly around until the indicator points to the gap or cut-out 10. In this position a thumb l 1~0596 o~ the user can be inserted through the gap or cut-out 10 and upward pressure then forces or flicks the Inner member 4 out of the outer member 5.
The outer surface of the inner member 4 is smooth except at the thumb grip 11 where it is stepped or otherwise shaped to enable a user to apply the required upward pressure to flick out the inner member 4. When the closure cap is in operative position as shown, e.g., in Figure 2, a ledge 14 at the lower end of the inner member 4 sits on the edge 15 around the mouth of the container 1 while an annular depending portion 16 of the inner member 4 enters the mouth of the container 1 so that the inner member 4 of the closure cap turns on the edge of the mouth of the con-tainer 1 when the inner member 4 is manipulated relative to the outer member 5.
Referring now to Figure 5, it will be noted that before appli-cation to the container 1, the closure is in the form of a one-piece molding comprising the inner member 4 and the outer member 5 interconnected by a frangible connection 6. In full lines in Figure 5, the closure cap is shown in one piece before application to a container 1 and in dot-and-dash lines the closure cap is shown in its operative position. The clos-ure cap as an integral unit i9 applied to a container 1 in a normalmanner and top pressure ls exerted on the closure cap to push the inner member 4 into the outer member 5, to break the frangible connection, to push the outer membr 5 into a position to embrace the surface of the con-tainer around its mouth and to seat the inner member 4 on or in the mouth.
If desired, a tamper-resistant feature may be incorporated by providing a web or webs 12, as shown in Figure 6 connecting the top of the înner member to the outer member. The web or webs 12 must be broken before the inner member can be removed and breaking can readily be l 160S~
effected during rotation of the inner mem~er to bring the thum6 grlp into registration with the gap or cut-out. A broken web in the closure cap of what should be an unopened container gives a clear visual indication that the contents of the container may have been tampered with.
In a modification shown in Figure 8, the outer member 5 has a continuous annular bead 8 on its inner surface, i.e., without the inter-ruption 13 and the inner member has a substantially annular bead 20 below a recess 22 on its outer surface with an interruption 21 therein as shown in Figure 8, below the thumb grip 11. When the closure cap is in opera-tive position, the bead 20 is below the bead 8 which is within recess 22 and the thumb grip 11 is out of registration with the gap 10. When the inner member is manipulated to bring the thumb grip ll into registration with the gap lO, the interruption 21 is below the gap 10 so that the beads 8 and 20 are not in engagement below the gap 10, and the inner member can be tilted and flicked out of the outer member.
In all cases, the interruption should be of sufficient size topermit easy removal of the inner member, e.g., 30 long. The gap 10 may be the same size or of differeDt size so long as it is big enough to receive the thumb of a user.
This invention relates to the provision of a closure cap for a container and to a container and closure cap assembly.
Children often attempt to tamper with containers of pills and the lilce and try to open such containers to get at the contents. Some-times children have succeeded in opening a container of pills with tragic results.

Figures 6 and 7 are detail views and Figure 8 is a modification of other aspects of this invention.
Referring to the drawings, 1 is a container which as a smooth inner surface 2 and an outer annular projecting ring 3. A two-part closure cap comprises an inner member 4 in the form of a plug and an outer member 5 in the form of a sleeve, the inner member 4 being disposed coaxially within the outer member 5. The outer member 5 has an internal annular recess 7 shaped to receive the annular projecting ring 3, the shape of the recess 7 and the ring 5 being such that it is relatively simple to push the outer member 5 downwardly over the ring 3 so that the ring 3 engages in the recess 7 but it is almost impossible to remove the member 5 again by a simple upward movement. The outer member 5 has an internal substantially annular bead 8 for engagement within an annular recess 9 in the outer surface of the inner member 4 and the outer member 5 also has an interruption 13 in the bead 8 forming a gap therein as 1 lB05~6 indicated in Figure 7. The inner member 4 has a thumb grip 11 an~ an embossed arrow or other mark on the top to indicate the position of the thumb grip 11. The interruption 13 in the substantially annular bead 8 is directly below or in the region of a gap or cut-out 10 in the peripheral top edge of the outer member 5 so that when upward pressure is applied to the thumb grip 11 of the inner member 4 through the gap or cut-out 10, the inner member 4 may be removed or pushed out of the outer membPr 5 in a tilting movement. It will be understood that pressure can be applied to the thumb grip 11 only when the inner member 4 is manipulated to bring the thumb grip 11 into registration with the gap or cut-out 10.
When upward pressure is applied to the thumb grip 11 to push the inner member 4 out of the outer member 5 to open the container 1, the inner member 4 first tilts because upward pressure on the thumb grip raises the near side of the inner member 4 so that the top of the inner member 4 inclines downwardly away from the gap or cut-out 10. In the opening movement, therefdre, the inner member 4 may be described as being flicked out of the outer member 5.
The assembly of the parts of the closure cap may be effected in such a way that the thumb grip 11 is out of registration with the gap or cut-out 10 in the periphery of the outer member 5 so that if the closure cap be applied automatically to a container, i.e., by machine, the closure cap will be seated on the container in a child-resistant position.
Then, in operation, to open the container a user moves the inner member 4 angularly relative to the outer member 5 until the thumb grip registers with the gap or cut-out 10 and then flicks out the inner member. To facilitate correct positioning of the inner member for openin~, the arrow or other indication referred to above may be provided on the top of the inner member, the inner member being pushed angularly around until the indicator points to the gap or cut-out 10. In this position a thumb l 1~0596 o~ the user can be inserted through the gap or cut-out 10 and upward pressure then forces or flicks the Inner member 4 out of the outer member 5.
The outer surface of the inner member 4 is smooth except at the thumb grip 11 where it is stepped or otherwise shaped to enable a user to apply the required upward pressure to flick out the inner member 4. When the closure cap is in operative position as shown, e.g., in Figure 2, a ledge 14 at the lower end of the inner member 4 sits on the edge 15 around the mouth of the container 1 while an annular depending portion 16 of the inner member 4 enters the mouth of the container 1 so that the inner member 4 of the closure cap turns on the edge of the mouth of the con-tainer 1 when the inner member 4 is manipulated relative to the outer member 5.
Referring now to Figure 5, it will be noted that before appli-cation to the container 1, the closure is in the form of a one-piece molding comprising the inner member 4 and the outer member 5 interconnected by a frangible connection 6. In full lines in Figure 5, the closure cap is shown in one piece before application to a container 1 and in dot-and-dash lines the closure cap is shown in its operative position. The clos-ure cap as an integral unit i9 applied to a container 1 in a normalmanner and top pressure ls exerted on the closure cap to push the inner member 4 into the outer member 5, to break the frangible connection, to push the outer membr 5 into a position to embrace the surface of the con-tainer around its mouth and to seat the inner member 4 on or in the mouth.
If desired, a tamper-resistant feature may be incorporated by providing a web or webs 12, as shown in Figure 6 connecting the top of the înner member to the outer member. The web or webs 12 must be broken before the inner member can be removed and breaking can readily be l 160S~
effected during rotation of the inner mem~er to bring the thum6 grlp into registration with the gap or cut-out. A broken web in the closure cap of what should be an unopened container gives a clear visual indication that the contents of the container may have been tampered with.
In a modification shown in Figure 8, the outer member 5 has a continuous annular bead 8 on its inner surface, i.e., without the inter-ruption 13 and the inner member has a substantially annular bead 20 below a recess 22 on its outer surface with an interruption 21 therein as shown in Figure 8, below the thumb grip 11. When the closure cap is in opera-tive position, the bead 20 is below the bead 8 which is within recess 22 and the thumb grip 11 is out of registration with the gap 10. When the inner member is manipulated to bring the thumb grip ll into registration with the gap lO, the interruption 21 is below the gap 10 so that the beads 8 and 20 are not in engagement below the gap 10, and the inner member can be tilted and flicked out of the outer member.
In all cases, the interruption should be of sufficient size topermit easy removal of the inner member, e.g., 30 long. The gap 10 may be the same size or of differeDt size so long as it is big enough to receive the thumb of a user.
