Description

(54) IMPROVEMENTS IN AND RELATING TO CONTAINERS AND CLOSURES (71) We, JOHNSEN & JORGENSEN (PLASTICS) LIMITED, a British Company, of Grinstead Road, London SE8 5AB, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to the provision of a container closure cap and to a container and closure cap assembly.
According to the present invention there is provided a container closure cap formed as an integral unit with an inner part disposed co-axially above an outer part, the two parts being interconnected by a frangible connection which is broken 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 container by the outer part embracing an outer surface of the container in the manner of a sleeve while 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.
The fact that the inner part of the closure cap can be removed only when it has been turned into a predetermined position forms a child-resistant feature in that it is not easy for a small child to open the container to get at the contents. Preferably the outer part of the closure cap has a gap or cut-out in the upper peripheral edge and the inner part has a thumb grip. The inner part is rotatable within the outer part but it is virtually impossible to push the inner part out of the outer part until the inner part is rotated to bring the thumb grip into alignment with the gap or cut-out.
In addition a tamper-proof feature may be incorporated by providing a web connecting the top of the inner part of the closure cap to the outer part. The web must be broken before the inner part can be removed and breaking can readily be effected during rotation of the inner part to bring the thumb grip 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.
The invention also includes a container closure cap comprising an inner part connected by a frangible connection to an outer part, the closure cap being applied to the container, 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 broken by the act of applying the closure cap to the container, the arrangement being such that the inner part can be removed only when it has been turned into a predetermined position relatively to the outer part to provide a child resistant feature to the closure cap.
The invention also includes a container closure cap 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 container, the frangible connection being broken when the closure gap 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 childresistant 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.
In order that the invention may be more clearly understood reference is now directed by way of example to the accompanying drawings in which: Fig. 1 is a longitudinal sectional view showing the closure cap in two positions; and Figs. 2 and 3 are detail views showing the tamper-proof feature.
In the drawings 1 is a container which has a smooth inner surface 2 and an outer peripheral annular projection 3. Before application to the container the closure cap is in the form of a one piece moulding com prising an inner part 4 which in operation forms a plug part and an outer part 5 which is connected to the inner part 4 by a frangible connection 6 and which in a position acts as a sleeve which seats on the outer surface of the container around the mouth.
The outer part 5 has an internal annular recess 7 shaped to receive the annular projection 3, the shape of the recess 7 and the projection 3 being such that it is relatively simple to push the outer part over the projection 3 so that the projection engages in the recess 7 but is almost impossible to remove the outer part 5 upwardly again.
The outer part 5 also has an internal substantially annular bead 8 for engagement within an annular recess 9 in the outside of the inner part 4 and the outer part also has a peripheral gap 10 or cut-out as shown in Fig. 2.
The inner part 4 has a thumb grip 11 and an embossed arrow 13 or other mark on the top indicating the position of the thumb grip.
The substantially annular bead 8 on the inside of the outer part 5 is interrupted in the region of the gap or cut-out 10 in the periohery of the outer part so that when upward pressure is applied to the inner part 4 adjacent to the gap or cut-out 10 the inner part 4 may be pushed out of the outer part 5.
In full lines in Fig. 1 the closure cap is shown as a one part moulding before application to a container 1 and the inner part 4 is also shown in dot and dash lines to indicate the position to be taken up by the inner part 4 in operation. The closure cap as an integral unit is applied to the container 1 in the normal manner. Top pressure is then applied to the closure cap and the frangible connection 6 is sheared so that the inner part 4 telescopes into the outer part 5. Before or after the telescoping action the outer part 5 is secured onto the container using the same continuous top pressure.
The moulding of the parts can 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 so that if the closure cap be applied automatically, i.e. by machine to- a- container the closure cap will be in- a child resistant position.
As illustrated in Figs. 2 and 3 a tamperproof web 12 may be provided so that a user may see whether the closure has been tampered with.
In operation to open the container a user moves the inner part 4 angularly relative to the outer part 5 until the thumb grip 11 registers with the gap or cut-out 10. This may easily be done by pushing the inner part 4 around until the arrow 13 points to the gap or cut-out 10. In this position a thumb of the user can be inserted through the gap or cut-out 10 and upward pressure forces the inner part 4 out ofthe outer part. It will be noted that in the illustrated embodiment where the closure cap is in operative position a- ledge 14 at the lower end of the inner part 4 seats on the edge 15 around the mouth of the container while an annular depending plug 16 enters the mouth of the container so that the cap 4 turns on the edge of the container when the cap is manipulated.
To sum up therefore it will be understood that for child resistance the thumb grip or thumb tab recess is hidden by the outer part after the inner part and the outer part have been telescoped together and becomes visible only when aligned with the gap or cut out.
Fig. 2 illustrates the closure cap before the parts have been telescoped together and Fig.
3 illustrates the closure cap after telescoping.
WHAT WE CLAIM IS: 1. A container closure cap formed as an integral unit with an inner part disposed co-axially above an outer part, the two parts being interconnected by a frangible connection which is broken 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 container by the outer part embracing an outer surface of the container in the manner of a sleeve while 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.
2. A container closure cap according to claim 1 wherein the frangible connection is a substantially annular diaphragm.

    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 childresistant 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.
    In order that the invention may be more clearly understood reference is now directed by way of example to the accompanying drawings in which: Fig. 1 is a longitudinal sectional view showing the closure cap in two positions; and Figs. 2 and 3 are detail views showing the tamper-proof feature.
    In the drawings 1 is a container which has a smooth inner surface 2 and an outer peripheral annular projection 3. Before application to the container the closure cap is in the form of a one piece moulding com prising an inner part 4 which in operation forms a plug part and an outer part 5 which is connected to the inner part 4 by a frangible connection 6 and which in a position acts as a sleeve which seats on the outer surface of the container around the mouth.
    The outer part 5 has an internal annular recess 7 shaped to receive the annular projection 3, the shape of the recess 7 and the projection 3 being such that it is relatively simple to push the outer part over the projection 3 so that the projection engages in the recess 7 but is almost impossible to remove the outer part 5 upwardly again.
    The outer part 5 also has an internal substantially annular bead 8 for engagement within an annular recess 9 in the outside of the inner part 4 and the outer part also has a peripheral gap 10 or cut-out as shown in Fig. 2.
    The inner part 4 has a thumb grip 11 and an embossed arrow 13 or other mark on the top indicating the position of the thumb grip.
    The substantially annular bead 8 on the inside of the outer part 5 is interrupted in the region of the gap or cut-out 10 in the periohery of the outer part so that when upward pressure is applied to the inner part 4 adjacent to the gap or cut-out 10 the inner part 4 may be pushed out of the outer part 5.
    In full lines in Fig. 1 the closure cap is shown as a one part moulding before application to a container 1 and the inner part 4 is also shown in dot and dash lines to indicate the position to be taken up by the inner part 4 in operation. The closure cap as an integral unit is applied to the container 1 in the normal manner. Top pressure is then applied to the closure cap and the frangible connection 6 is sheared so that the inner part 4 telescopes into the outer part 5. Before or after the telescoping action the outer part
    5 is secured onto the container using the same continuous top pressure.
    The moulding of the parts can 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 so that if the closure cap be applied automatically, i.e. by machine to- a- container the closure cap will be in- a child resistant position.
    As illustrated in Figs. 2 and 3 a tamperproof web 12 may be provided so that a user may see whether the closure has been tampered with.
    In operation to open the container a user moves the inner part 4 angularly relative to the outer part 5 until the thumb grip 11 registers with the gap or cut-out 10. This may easily be done by pushing the inner part 4 around until the arrow 13 points to the gap or cut-out 10. In this position a thumb of the user can be inserted through the gap or cut-out 10 and upward pressure forces the inner part 4 out ofthe outer part. It will be noted that in the illustrated embodiment where the closure cap is in operative position a- ledge 14 at the lower end of the inner part 4 seats on the edge 15 around the mouth of the container while an annular depending plug 16 enters the mouth of the container so that the cap 4 turns on the edge of the container when the cap is manipulated.
    To sum up therefore it will be understood that for child resistance the thumb grip or thumb tab recess is hidden by the outer part after the inner part and the outer part have been telescoped together and becomes visible only when aligned with the gap or cut out.
