Abstract
A closure comprises an inner closure member 48 adapted for screw engagement with the neck of a container, and an outer closure member 12 for inter-engagement with the inner member and capable of rotation with respect thereto. An inertia block 23 located on the outer member is capable of movement with respect thereto between an engaged position and a disengaged position. Detent means 55 provided on the inner member are adapted to engage with the inertia block in the engaged position to provide torque transmission between the two members for unscrewing the closure, the arrangement being such that by striking the closure against a surface, the inertia block is caused to move from the disengaged position to the engaged position. A ratchet arrangement 32, 50 between the two members provides torque transmission for applying the closure. <IMAGE>
Description
SPECIFICATION
Child resistant closure
The present invention relates to child resistant
closures.
Child resistant closures at the presenttime are
extensively used in connection with the packaging of
medicines, drugs and other dangerous materials.
These child resistant closures are generally based
upon a screw type closure having a two-part construction in which an outer closure member overlays an inner closure member. Ratchet means are usually provided between the outer closure
member and the inner closure member so that on screwing the outer closure member in a sense such astoapplytheclosuretoacontainerengagement between the outer member and the inner member takes places to effect the application of the inner closure member to the container, but on attemptto
unscrew the outer closure, the ratchet members disengage and simply click over one with respectto the other in a pawl type arrangement.In these known closures, secondary engagement means are provided so that on depressing the outer closure member against a spring loading, the secondary engagement means are effective between the inner closure and the outer closure thereby permitting unscrewingofthe innerclosurefromthecontainer.
While effective, these devices suffer from the disadvantage that the old and the infirm are disadvantaged because the action of applying pressure and simultaneously a turning motion is virtually impossibleforthose with arthritic hands.
Accordinglythereisa considerable needfora closure which has a child resistantfeature and does not require the action of depression of the outer closure with respecttotheinnerclosurewhile simultaneously performing an unscrewing action.
According to the present invention, therefore, there is provided a child resistant closure comprising
an innerclosurememberadaptedforscrew engagement with the neck of a container,
an outer closure member in interengagement with theinnerclosurememberandcapableofrotation with respect thereto,
an inertia block located by one of said members and capable of movement with respect thereto between an engaged position and a disengaged position and detent means provided on said other member adapted to engage with said inertia block in the engaged position to provide torque transmission between said inner closure member and said outer closure member,
the arrangement being such that by striking the closure member against a surface the inertia block is caused to move from the disengaged position to the engaged position.
According to one embodiment of the invention, the inertia block detent means may be adapted to provide torque transmission in one sense only. In a specific embodiment ofthis feature, the engaging end ofthe inertia block may be contoured or shamfered so that engagement with the detent means in otherthan said one sense will result in a
reaction between the detent means and the inertia
block which will serve to urge the inertia blocktothe disengaged position.
In a further embodiment of the invention, ratchet
means may be provided between the inner closure
and the outer closure whereby on rotation ofthe
outer closure member in a first sense to effect the screwengagement between the innerclosure and the neck of the container to which it is applied, the
ratchet means engage so that rotation of the outer
closure member is transmitted to the inner closure
member, the arrangement being such that on
rotation of the outer closure member in a second sense, the ratchet means is caused to disengage to
allow rotation of the outer closure member with
respect to the inner closure memberwhen the inertia
block is in a disengaged position.
In a further embodiment of the invention, the said other closure member may comprise a stop element which, when the ratchet means are engaged, serve to obtu rate the path of the inertia block to prevent
movement thereof to the engaged position. The inertia block and/orthe detent means may be configured such that on rotation ofthe outer closure member otherthan in said one sense, the inertia block and detent interact to urge the block to the disengaged position. The locating means for the inertia block may be carried by the outer closure member and the detent means may be carried by the inner closure member. The detent means and the stop element may be comprised by a projection movable circumferentially into and out of the block path.The outer closure member may be marked to indicatethe part ofthe closure to be struckagainsta sunfacetocausetheinertiablockto movetothe engaged position. In a further embodiment ofthe invention, the stop element may be of sufficient arcuate extentthatthe outer closure must be partially rotated from the position in which the ratchet means are in engagement before the inertia block can be moved to the engaged position. This latterfeature has the advantage that with the ratchet elements in the engaged position, the stop acts to maintain the inertia block in its disengaged position thus preventing accidental movement of the inertia blockto the engaged position hence permitting unauthorised or accidental removal.
In a particular embodiment of the present invention,the inertia block is located substantially centrally ofthe closure member in which it is located and movable radially upwardly of said member to an engaged position. Where the location of the inertia block is carried by the outer closure, the mark provided on the outer closure is disposed substantially co-radially with the path of said inertia block and towards the circumference thereof two indicate the portion of the closure that needs to be struck against a surface in orderto induce the block to move from a disengaged to an engaged position.

Outer closure member 10 comprises a crown portion 11 1 having 11 substantially cylindrical depending skirt 12. The skirt is provided on its outer surface 13 with a plurality of longitudinal ribs 14 providing a surface easily grasped bythefingers in use.
The depending skirt is provided on its inner surface with an upper substantially cylindrical surface 15 and a lower cylindrical surface portion 16, said lower cylindrical surface being of slightly greater radial extentthan upper cylindrical surface 15 and interconnected therewith by intermediate surface portion 17.
Lower cylindrical surface 16 terminates towards its lower end in an annular rabbet 18 and an inwardly projecting annular bead 19.
The underside of the crown ofthe closure carries a substantially downwardly depending cylindrical boss 20 having a central cutaway portion 21 providing a passage 22 adapted to accommodate an inertia block 23. The passage 22 is defined by a pair of spaced chordal walls 24and 25 and an end wall 26 defining a passage or housing adapted to locate and accommodate inertia block 23.The wall 25 and the portion ofthe boss 20 juxtaposed thereto is provided towards the end thereof juxtaposed end wall 26 with afriction member 27. Friction member 27 is located by means of molded webs 28,28' disposed on each side of member 27 which member 27 is provided with a pointed tongue 29 projecting into passage 22 and is adapted to bear lightly against an adjacent surface of inertia block 23 disposedtherein.
The inertia block 23 maybe ofsubstantially rectilinear cross section (see Figure 6) with the tongue 29 offriction member 27 being inclined at a slight angle to the perpendicularto the underside of crown 11 of the outer closure member 10 that the area of contact between a side wall of block 23 and friction member 29 over a portion 30 only of the side wall.
The arrangement shown in Figure 5 is an alternative embodiment ofthe present invention wherein the portion of block 23 at least in the wall adjacent the friction member 27 is not rectilinear, but inclined ata small angletothe perpendicular to the crown portion 11 ofclosure 10to provide a small area of contact 30 between the wall and the substantially perpendicular pointed tongue portion offriction member 27.
One end 62 of inertia block 23 is angled to provide an inclined end wall.
The undersurface 31 of crown portion 11 is provided with a downwardly directed arcuate pawl member 32 of substantially regular cross section and terminating in an end 33 defined buy a surface substantially perpendiculartothe undersurface 31 of crown 11 so thatthe lower edge 34 defines a pawl edge adapted to cooperate with a corresponding ratchet element provided on an inner closure member as hereinafter described.
The uppersurface35 is provided with a hemispherical raised dot 36 towards the circumferential edge thereof, said dot 36 being located on the diameter containing the centre line of the passage 22 and on the side of the centre ofthe crown 11 remote from end wall 26 defining passage 22.
The innerclosure member40 is shown generally in
Figures3 and 4 ofthe accompanying drawings and comprises a crown 41 having a substantially cylindrical depending skirt42 provided on the internal surface 43 with a screw th read 44 adapted to engage with a correspondingly threaded neck of a container to which the closure is adapted to be applied.The outer surface 45 is provided towardsthe lower end with an outwardly projecting annular bead 46,the arrangement being such that on applying outerciosure memberl0overinnerclosuremember 40, the lower cylindrical surface 16 of depending skirt 12 of closure member 10 overlaystheoutersurface 45 ofinner closure 40 and bead 46 snaps into annular rabbet 18 with bead 19 providing positive engagement under bead 46to secure the inner closure member40 within outer closure member 10 for relative rotation one with respectto the other.
The crown 41 of inner closure member 40 is provided on its upper surface 47 with a concentrically disposed and upwardly extending cylindrical portion 48. Cylindrical portion 48 has a diameter smallerthan that of the periphery of the crown portion 41 to define an annular crown surface 49 having a pair of diametrically disposed ratchet members 50.Each ratchet member comprises an abutment surface 51 steeping inclined to surface 49 and radially disposed with respect thereto and an arcuateflanksurface 52,the arrangement being such that rotation ofthe outer closure member 10 with respect to inner closure member 40 in first direction will bring the end 33 of pawl member 32 into engagement with abutment surface 51 of ratchet member 50 so that continued movement will cause rotation of the inner closure member 40 with outer closurememberlO bythedrivetransmittedfrom outerclosurememberlOvia pawi member32and ratchet member 50. Rotation of the outerclosure member in the opposite sense will result in disengagement between the end 33 of pawl member 32 and abutment surface 31 of ratchet member 50 so that outer closure member 10 rotates in said opposite sense with respect to inner closure member 40 until the lower edge 34 of pawl 34 of pawl member 32 engages with arcuate flank surface 52 of ratchet member 50. Continued rotation ofthe outer closure member is sufficient to cause the pawl member32to flex as the lower edge 34 rides up theflank surface 32 and to "snap over" the extremity of ratchet member 50 with a characteristic clickthus allowing continued rotation of outer closure memberwith respect to inner closure member40.
The upward cylindrical portion 48 is provided on the internal surface thereof with a pair of detent members 55. The members 55 are diametrically disposed one with respect to the other and each member is defined by a block engaging wall 56, an arcuatewall 57 and a substantially radially disposed rearward wall 58. The angularjuxtaposition ofdetent members 55 with respect to ratchet members 50 is suchthatwiththepawl member52 in driving engagement with ratchet member 50, the arcuate surfaces 57 obturate, at least in part, the path of radial movement of block 23 as shown in Figure 7.In this way, in the event of any movement or slight rotation ofthe outer closure in a pawl disengaging sense, the arcuate surface 57 of detent member 55 juxtaposed the open end of passageway 22 will serve to retain block 23 within said passage i n boss 20 and prevent the block 23 moving substantially radially outwardly thereof. This acts as a safety means so that in transit, closures will not be delivered to a customer in a condition whereby the application of a simple unscrewing motion of the outer closure 10 will result in release ofthe inner closure member 40.
Starting from the position shown in Figure 7, in order to open the closure, the outer closure is rotated anti-clockwise as shown in Figure 8 to disengage pawl member 32 from ratchet member 50 and atthe sametimetomovedetentmember55outofits obturating position in the path of movement of block 23. The container is then grasped in the hand and the closure tapped against a surface so as to arrest movement of the closure suddenly, the portion of the closureto be tapped againstthe surface being that juxtaposed raised dot 36. The sudden arresting ofthe translational movement of the closure allows the inertia of block 23 to carrythe block along a radial path until the extremity 60 engages cylindrical inner surface of upward cylindrical portion 48 (see Figure 8).Rotation ofthe outer closure anti-clockwise will then bring the back portion 61 of block 23 into engagementwith block engaging wall 56 of detent member 55, so that continued anti-clockwise rotation of the outer closure will cause the inner closure also to be driven anti-clockwise to unscrew the innerclosurefrom the neckofthe containerto which it is applied.
To resecure the closure, simple rotation ofthe outer closure member as shown in Figure 9 causes the inclined surface 62 to be brought into abutting engagement with the corner of detent 55 defined by wall 58 and wall 57. The inclined surface produces a reaction to the block which causes the block to move radially inwardly to a disengaged position so that when pawl member32 is brought into driving engagement with ratchet member 50, block 23 is accommodated substantially whollywithin boss 20 and radial movement thereof is limited by arcuate wall 57 of detent member 55. Continued clockwise rotation of the outer closure causes driving of the inner closure to screw the inner closure member on to the neck ofthe container.
The device described above has a number of significant advantages:
1. It has a positive screw action applied in the normal way ofany other screwthreaded bottle closure.
2. There is automatic disengagement between the block 23 ofthe inner closure and the block is physically retained in a disengaged position to prevent accidental movement to an engaging position during travel movement and other handling.
3.Two distinct steps are required in order to open the closure:
a) The outer closure must be rotated in an anti-clockwise direction sufficient to move detent 55 out of the movement path of block 23.
b) An inertia effect must be applied to "jerk" or otherwise move block 23 radially outwardly so that continued anti-clockwise movement engagement between the block 23 and detent 55 so that torque drive is transmitted via boss 20, block 23 and detent 55 to provide an unscrewing movementtransmitted from the outer closure membertothe inner closure member.
