Definitions

• 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.
• 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 the closure, in order to release the closure from the container body.
• 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.
• the cap partially obscures the view of the contents of the container.
• the patient only has to take half a tablet dose.
• a further disadvantage of the present containers is that once the 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.
• container comprising a hollow body, a closure movable between a closed condition and an open condition, a locking part for securing the closure in the closed condition, the locking part being moveable between a locking position and an unlocked position, and actuator means for moving the locking part from the unlocked position to the locking position as the closure is transferred between the respective conditions.
• the arrangement is such that as the closure is moved to the open condition and the locking part is in the unlocked position the actuator means moves the locking part to the locked position.
• the arrangement is such that as the closure is moved to the closed condition and the locking part is in the unlocked position the actuator means moves the locking part to the locked position.
• the actuator means helps to ensure that the locking part is in a locking position after the closure has been opened and/or closed.
• the actuator means automatically moves the locking part as the closure is being opened and/or closed; therefore the child resistant feature is automatically activated when necessary during the opening operation and the closing operation.
• the present invention aims to overcome the disadvantages we have found of the prior art containers by providing a locking arrangement for a container that is automatically placed in a locked condition.
• closure and the locking part comprise respective cooperating locking elements, the arrangement being such that as the closure is removed from the body to open the container, the actuator means moves one of the locking elements relative to the other locking element.
• the arrangement of the cooperating locking elements located on the closure and the locking part is such that as the closure is pushed back onto the body to close the container, the actuator means moves one of the locking elements relative to the other locking element.
• the locking part carries an indicator that must be aligned with an indicator on the hollow body and/or the closure, the arrangement being such that in use the indicators are moved from an aligned position to a misaligned position by the actuator means.
• the cooperating locking elements are located on the body and the locking part, the arrangement being such that as the closure is removed from the body to open the container, the actuation means moves one of the locking elements relative to the other locking element.
• the arrangement of the cooperating locking elements located on the body and the locking part is such that as the closure is pushed back onto the body to close the container, the actuation means moves one of the locking elements relative to the other locking element.
• the locking part is preferably an annular locking ring.
• the actuator means comprises an elongate member disposed on the inside of the closure, and the locking ring comprises a ramp, the ramp being sloped such that as the elongate member makes contact with the ramp and is slid progressively along a surface of the ramp rotation of the locking ring results such that the indicators on the body and/or closure and the locking part are no longer aligned.
• the arrangement of the elongate member and the ramp is such that as the closure is removed from the body to open the container, the elongate member makes contact with a first surface of the ramp and rotation of the locking ring results such that the indicators on the body and/or closure and the locking part are no longer aligned.
• the arrangement of the elongate member and the ramp is such that as the closure is placed back onto the body to close the container and the indicators are aligned, the elongate member makes contact with a second surface of the ramp and rotation of the locking ring results such that the indicators on the body and/or closure and the locking part are no longer aligned.
• the ramp protrudes from a radially inner surface of the locking ring.
• the ramp is a channel formed in the wall of locking ring, the central axis of the channel being at an angle from the axis of the ring.
• the elongate member is a flexible cantilever.
• the elongate member is hook shaped cantilever, extending from the inside surface of the closure.
• the locking part is preferably located between the body and the closure.
