Description

<div class="application article clearfix" id="description"> WO 2004/041671 PCT/SE2003/001704 Security container with locking closure and method for locking a closure The present invention relates to a container which can hold tablets or liquids, for example, for use in the pharmaceutical, chemical and food industries and in particular to a locking arrangement for a container and/or a secondary containment region for a container. Containers that have child resistant features are now generally available but these containers are typically very difficult for elderly or disabled persons to open. Reference should now be made to US patent No. 5908125 and other patents in the same area of technology. In general, child resistant containers require the user to simultaneously squeeze and turn the closure, or push and turn die closure, in order to release the closure from the container body. However, elderly persons or persons with dexterity problems find that the force required to squeeze or push the closure and simultaneously rotate the closure is too great or that they experience pain in attempting to open the closure. Those suffering from rheumatoid arthritis and osteoarthritis will find that they have to avoid any movement, which involves gripping, twisting or bending of the wrist. Known child resistant containers comprise a cap locking arrangement whereby the user has to turn a cap and align two dots on the respective outer surfaces of the container and the cap. In this position the cap can be pushed open. However, we have found that after the cap has been placed back on the container the user has to remember to turn the cap again so that the two dots are no longer aligned otherwise the container is more readily opened and is no longer child resistant. Furthermore, we have found that when this type of container is opened, the cap partially obscures the view of the contents of the container. Furthermore, for some tablet pharmaceuticals the patient only has to take half a tablet dose. A further disadvantage of the present containers is that once die tablet has been removed from the container it has to be either stored in a separate location or placed back into the container with the other tablets. In this arrangement the part tablet can be hard to find at a later time. In a first aspect, the present invention provides a locking arrangement for a closure on a container, the container comprising a hollow body formed with an opening, and the closure being attached to the body and movable between a closed position and an open position and vise versa; a locking part for locking the closure in the closed condition, the locking part provided between the container body and the closure, and moveable on the body; an actuator attached to the closure in the form of an element extending away from the inner surface of the closure; wherein the moveable locking part comprises a ramp having upper and lower inclined surfaces that are sloped from the axial direction of the locking part, and wherein the actuator has means for making contact with said upper or lower inclined surfaces on the moveable locking part during opening or closing of the closure so as to move the locking part to a position in which it locks the closure; characterized by a circumferential flange on the inside surface of the locking part; Intellectual Property \ 1 Office ot /- I 2 8 AUG 2007 !

In Figures 1 to 11, the first embodiment of a container according to the present invention is depicted. The container comprises a hollow body 1 for holding solid or liquid contents and a closure 2, which closes the container. A locking part in the form of a locking ring 3 is provided between the body 1 and closure 2. The locking ring 3 is rotatable on the body 1. An indicator arrow-A is located on the-body -1-and an indicator arrow B is locatedon the closure 2. The locking ring 3 also carries an indicator arrow C and it is only when the indicator arrow C is aligned, by turning the locking ring 3, with the indicator arrows A and B (see Figure 2) that the closure 2 can be opened by lifting or flipping the projecting edge 4 of the closure 2. Clearly, an indicator arrow need only be provided on either the body 1 or the closure 2 but the user benefits from being able to align indicator arrow C on the locking ring 3 with either indicator arrow A or indicator arrow B. The container also comprises actuator means in the form of an elongate member 6 that extends in a direction away from the inner surface of the closure 2. The member 6 comprises a hook shaped distal end 6a. Disposed between the distal end 6a and the closure 2 is a wedge shaped lug 10. The locking ring 3 is located on the body 1 by way of a snap fit between circular rib formed on an annular shoulder (not shown) on the body 1 and a corresponding circular recess 12 formed adjacent the lower inner edge of the ring 3. The arrangement of the ring 3 and the body 1 is such that the ring 3 is secured to the body 1 but will rotate freely on the body 1. In order that the closure 2 is locked onto the body 1, the locking ring 3 has a circumferential flange 8 on its inside surface. This flange 8 is formed with a recessed portion 9 through which the hook 6 and lug 10 can pass during opening and closing of the closure 2 if the arrows A, B, C are aligned. The lug 10 will sit under the flange 8 when the arrows are not aligned, thereby locking the closure 2 onto the body 1. The Inciting ring 3 comprises a ramp 7 that is sloped from the axial direction of the ring 3 and extends from the inner surface of the ring 3. There is a gap 13 between the uppermost part of the ramp 7 and the flange 8 through which the lug 10 may pass when the arrows A, B, C are aligned. The ramp 7 comprises an upper inclined surface 14 and a lower inclined surface 16 (hidden in the Figures). The arrangement is such that if the arrows A, B, C are aligned and the closure 2 is opened the lug 10 passes through the opening 9 and the distal end 6a of the hook WO 2004/041671 PCT/SE2003/001704 6 will make contact with the lower inclined surface 16 of the ramp 7 and rotate the locking ring 3 i.e., back to the locked position. Also, the arrangement is such that if the arrows A, B, C are aligned and Ihe closure 2 is closed the distal end 6a of the hook 6 will make contact with upper inclined surface 14 of the ramp 7 and rotate the locking ring 3 i.e., back to the locked position. In this respect, it should be noted that the locking ring 3 is freely rotatable on the body 1 once the hook 6 has travelled down the ramp 7. In the embodiments shown the locking part is preferably in the form of a locking ring 3, however the locking part maybe a non-aimular shape for example a slideable element that is moveable by the actuator means in an arc or linear direction. As an alternative, the ramp 7 could include a channel, which captures the tip. of the hook 6 at the bottom of the ramp 7 whereby the hook 6 is only released wheal it has travelled to the top of Ihe ramp 7. With this arrangement, the indicator arrow C is not aligned when the closure 2 has opened and the user can simply push the hook 6 over the flange 8 to close the closure 2. The distal end 6a acts as an actuator that ensures that the respective arrow indicators are misaligned following the opening and/or closing of the container. The distal end 6a automatically moves the arrow indicators out of alignment during the opening operation and if necessary the closing operation. Therefore the child resistant feature is automatically activated during the opening operation and if necessary during the closing operation. It should be noted that the hook 6 is flexible so that it is possible to push the closure 2 closed without aligning the hook 6 with the recessed portion 9. The lug 10 is sloped corresponding to the slope on the flange 8 so that it can simply be pushed over the flange 8 until Ihe lug 10 slips beneath the flange 8 to lock the closure 2 onto the body 1. The width of the recessed portion 9 is such that when the arrows A, B, C are aligned and the hook 6 sits at the bottom of the ramp 7,.the lug 10 will be free to move out of the locking ring 3. The body 1 in this embodiment has an annular opening 11 that is sealable by an annular rim 12 on the closure 2. This sealing arrangement helps prevent the ingress of water vapour, which could affect the stability of the contents and also acts to prevent leakage if the contents are liquid. The flange 8 and the annular opening 11 form a secondary containment volume 17. The volume 17 and the internal volume of the body 1 are separated from each other by an annular wall (not shown in the Figures). The volume 17 may be used to store material, such as part or whole pharmaceutical tables that have been removed from the container body 1. The containment volume 17 also provides an area that may be used to inspection Ihe material that has been removed from the body. In Figures 12,13 and 14, a second embodiment of a container according to the present invention is depicted. The container comprises a tubular hollow body 20 holding solid or liquid contents and a closure 21, which closes the container. A locking ring 23 is provided WO 2004/041671 PCT/SE2003/001704 between the body 20 and closure 21 which can rotate between body 20 and closure 21. An indicator arrow D is located on body 20 and an indicator arrow E is located the locking ring 23. As with the first embodiment it is only when the indicator arrows are aligned, by turning the locking ring, that the closure 21 can be opened by lifting or flipping the projecting edge 24 of the closure 21. In Figures 13 and 14, the closure 21 has been opened and the user is able to take out the contents. Since the closure 21 is hinged to the body 20 at point 25, there is no obstruction to emptying the contents as the closure 21 can sit right back as far as the hinge point 25 will allow. The closure 21 is formed with an annular collar 25 extending around the perimeter of the closure 21. Extending from an inner surface of the closure 21 is an elongate member 26 formed with a frusto conical end 28 at the distal end thereof. A wedge shaped locking lug 38 is formedon an outer.surfacejof.the annular.collar^5._. _. ... The locking ring 23 comprises an outer annular collar 31 and a radially inner annular track 32 formed with an inner annular channel and an upper annular slot 34. The inner annular channel is directly below the slot 34. The width of the slot 34 is less than the width of the annular channel. At one point on the slot 34 the width increases forming a circular access hole 36. The outer annular collar 31 is formed with a channel 37 that is sloped from the axial direction of the ring 23. The locking ring 23 is located on the body 20 by way of a snap fit between a circular rib (not shown) formed on the body 20 and a corresponding circular recess (not shown) formed adjacent the lower inner edge of the ring 23 such that the ring 23 is secured to the body 20 but will rotate freely on the body. The arrangement is such that if the arrows D and E are aligned the end 28 will be adjacent the hole 36 and the lug 38 will be at the lowermost end of the channel 37 and the closure 21 can be opened. As the closure 21 is opened the end 28 will pass through the hole 36 and the lug 38 will make contact with the upper inclined surface of the channel 37 and rotate the locking ring 23 i.e., back to the locked position. Also, the arrangement is such that if the arrows D and E are aligned and the closure 21 is closed the end 28 will pass through the hole 36 and then the lug 38 will make contact with lower inclined surface of the channel 37 and rotate the locking ring 23 i.e., back to the locked position. In this respect, it should be noted that the locking ring 23 is freely rotatable on the body 20 once the lug 38 has travelled down the channel 37. The body 20 in this embodiment has an annular opening 40 formed in an upper wall 41. The opening 40 is sealable by an annular rim 42 on the closure 2. This sealing arrangement helps prevent the ingress of water vapour which cold affect the stability of the contents and also acts to prevent leakage if the contents are liquid. The upper wall 41 and annular track 32 form a secondary containment volume 43. The volume 43 may be used to store material, such as 8 WO 2004/041671 PCT/SE2003/001704 part or whole pharmaceutical tables that have been removed from the container body 20. The containment volume 43 also provides an area that may be used to inspection the material lhat has been removed from the body. The lug 38 acts as an actuator that ensures that the respective arrow indicators are misaligned following the opening and/or closing of the container. The lug 38 automatically moves the arrow indicators out of alignment during the opening operation and if necessary the closing operation. Therefore the child resistant feature is automatically activated during the opening operation and if necessary during the closing operation. In Figures 15 to 19, a third embodiment of a container according to the present invention is depicted. The third embodiment comprises many common features as the first embodiment herein before described and the same reference numbers have been used to depict those common features. The third embodiment container 50 comprises a hollow body 51 for holding solid or liquid contents and a closure 52, which closes the container. A locking part in the form of a locking ring 53 is provided between the body 51 and closure 52. The locking ring 53 is rotatable on the body 51. An indicator arrow B is located on the closure 52. The locking ring 53 also carries an indicator arrow C and it is only when the indicator arrow C is aligned, by turning the locking ring 53, with the indicator arrows B (see Figure 15) that the closure 52 can be opened by lifting or flipping the projecting edge 54 of the closure 52. The container 51 also comprises actuator means in the form of an elongate member 6 that extends in a direction away from the inner surface of the closure 52. The member 6 comprises a hook shaped distal end 6a. Disposed between the distal end 6a and the closure 52 is a wedge shaped lug 10. The locking ring 53 is located on the body 51 by way of a snap fit between circular rib formed on an annular shoulder (not shown) on the body 51 and a corresponding circular recess (not shown) formed adjacent the lower inner edge of the ring 53. The arrangement of the ring 53 and the body 51 is such that the ring 53 is secured to the body 51 but will rotate freely on the body 51. The operation and function of the locking ring 53 and the actuator 6 is substantially the same as the description of the corresponding features of Figures 1 to 11 of the first aspect of the invention. It will be noted however that the locking ring 53 is disposed substantially about the central axis of the container'51. In this embodiment the container 51 is formed with an opening 55 located at one side of the container 51. The opening 55 provides access to the interior volume of the container 51. A solid panel 63 seals a portion of the upper volume of the container 51. The panel 63 and an annular collar 61 form a second containment volume 64. A third containment volume 65 is formed by a portion of the panel 63, a portion of the radially outermost wall of the body 51 9 WO 2004/041671 PCT/SE2003/001704 and actuate wall 67. The second and third containment volumes 64,65 may be used to store solids of liquids. The second and third containment volumes 64,65 may be used for storing pharmaceutical products such as pills or capsules and are particularly useful for storing partial pills or capsules. The containment volumes 64,65 are sealed by the closure 52. The containment volumes 64, 65 also provide areas that may be used to inspection the material that has been removed from the body. In Figures 20 to 23, a fourth embodiment of a container according to the present invention is depicted. The fourth embodiment comprises many common features as the first embodiment herein before described and the same reference numbers have been used to depict those common features. The container 70 of the third embodiment differs from that of the first embodiment by the fact thatthe. closure 72 of .the, container 70 extends across the uppermost end.volume of-the hollow body 1. The horizontal cross-section of the closure 72 is substantially the same as the horizontal cross-section of the body 1. A solid panel 74 seals a portion of the upper volume of the container 1. The panel 74 and an upwardly extending collar 76 form a second containment volume 68. The second containment volume 68 may be used for storing pharmaceutical products such as pills or capsules and is particularly useful for storing partial pills or capsules. The containment volume 68 is sealed by the closure 72. The containment volume 68 also provides an area that may be used to inspection the material that has been removed from the body. 10 </div>
