The present invention relates to a dispenser. In one non-exclusive aspect the invention concerns a pharmaceutical dispenser for use by a patient to dispense a daily amount of medication.
Medications particularly those associated with addiction are commonly given via staged supply for up to a week. The concept of harm minimisation is key in limiting the amount of medication a person has access to at any one time thus preventing medication misadventure and polypharmacy.
Take away doses as part of this regime are doses that must be placed into individual containers that are labelled. One method by which these medications are provided to a patient includes a plastic safe having six compartments each for housing medication for six of the seven days of a calendar week. The safe has a lid which is manually actuated by the patient to access the medication in a specific compartment. The safe further includes a locking system to prevent a patient from accessing more than a single day's medication. To this effect the locking system includes a timer which enables a user to actuate the safe once a day in order to access the medication for that day. When the medication in each of the compartments has been exhausted at the end of a six-day period, corresponding to the six compartments, a user can present the safe at a pharmacy where the six compartments are replenished with medication for six days.
Certain problems have been identified in known safes used for dispensing medication. One significant issue which has occurred in certain instances is that a patient is able to remove the lid of the safe at the end of the six-day period to gain access to the locking system and tamper therewith. It has also been the case that the locking system of known safes have become defective and that the medication could only be retrieved from the safe by a suitably skilled person located offsite from the dispending pharmacy. This could possibly lead to a party illegally sending a schedule 8 drug held in the defective safe via the postal service to a technician able to retrieve the medication within the safe. The technician receiving the safe and medication invariably will not be legally permitted to receive and hold scheduled medication. Once the medication has been retrieved from the defective safe it will be illegal to return the medication via the postal service to the dispensing pharmacy. Further, retrieval of the drugs from the defective safe typically results in the destruction of the safe and the consequential cost implication
It is an object of the present invention substantially to overcome or ameliorate one or more of the problems associated with existing pharmaceutical dispensers employed for dispensing daily dosages of medication or at least to provide a useful alternative.

Preferred embodiments of the invention will be described hereinafter, by way of examples only, with reference to the accompanying drawings, wherein:
In the description below a dispenser is provided for use as a pharmaceutical dispenser. It will of course be appreciated that the dispenser can found application in various industries where a dispenser with a programmable delivery system is required for dispensing/delivering product. The dispenser is accordingly not limited to the pharmaceutical application discussed below.
The lid 14 includes a lid opening 20 which is adapted to be aligned with a single compartment 16 of the base 12 upon rotation of the lid 14. This configuration provides that a user patient is able to access the prescribed pharmaceutical held within a single compartment 16 only. A lid member 22 is operatively associated with the lid 14 and includes a lid member opening 24 which is in register with the lid opening 20. The lid member 22 is adapted to rotate with the lid 14 about the base 12 to provide access to a single compartment 16.
The lid 14 includes a lid attachment formation 26 and the base 12 includes a base attachment formation 28 operatively adapted to engage the lid attachment formation 26 to secure the lid 14 to the base 12 while permitting pivotal movement of the lid 14 relative to the base 12. In this embodiment the lid attachment formation 26 provides a lid bayonet formation 30 which is operatively adapted to engage a complemental base bayonet 32 formation of the base attachment formation 28. The lid bayonet formation 30 and the base bayonet formation 32 are configured to define a lid release position in which they co-operate so that the lid 14 is adapted to be removed from the base 12 as described below.
The lid 14 includes a gripping protrusion 34 outwardly extending from an outer surface 36 of the lid 14 and provides purchase to a finger of a user patient rotating the lid 14 relative to the base 12. The gripping protrusion 34 is located proximate the lid opening 20.
The pharmaceutical dispenser 10 includes a sub-lid assembly 38 operatively adapted to control pivotal movement of the lid 14 relative to the base 12. The sub-lid assembly 38 includes a rotator 40 operatively attached to the lid 14. To ensure the lid 14 is correctly orientated with the rotator 40 the lid 14 includes a lid keyway formation 42 which is operatively adapted to engage a complemental rotator keyway formation 44 of the rotator 40.

The locking arm 48 is movable between (i) an arm locked position 58, depicted in
The actuating lever 52 is moveable between (i) an actuator engaged position 62 in which the actuating lever 52 secures the locking arm 48 in the arm locked position 58, and (ii) an actuator disengaged position 64, in which the locking arm 48 is permitted to move to the arm released position 60. It is pointed out that the actuating lever 52 is pivotally mounted to a pivot point 53 and will in use pivot/rock between the actuator engaged position 62 and the actuator disengaged position 64. It will be appreciated that by controlling the position of the actuating lever 52 it will be possible to control the position of the locking arm 48 and whether the lid 14 is permitted to undergo rotation to allow a patient user access to a compartment 16 holding a bottle filled with methadone.
Rotation of the lid 14 is effected by a user patient manually applying torque to thereto. Such torque applied by the patient user will have the effect also of rotating the rotator 40. Rotation of the rotator 40 will cause the re-setting formation 50 to engage the actuating lever 52 so as to move the actuating lever 52 from the actuator disengaged position 64, depicted in
Referring to
The locking arm 48 includes biasing means 72, here a torsion spring, to bias the locking arm 48 to the arm released position 60. The locking arm 48 further includes a locking flange 74 which outwardly extends from an outer surface of the locking head 66. The locking flange 74 is operatively adapted to be engaged by a flange formation 76 of the rotator 40 so as to move the locking flange 76 between a flange locked position 78, shown in
As shown in
The sub-lid 38 assembly includes a first and second solenoid 88, 90. The first solenoid 88 includes a first plunger 92 and the second solenoid 90 includes a second plunger 94. The first plunger 92 is moveable between a first extended position 96, shown in
The actuating lever 52 is located in the actuator engaged position 62 when the first plunger 92 is located in the first extended position 96 and the second plunger 94 is located in the second retracted position 102. Conversely the actuating lever 52 is located in the actuator disengaged position 64 when the first plunger 92 is located in the first retracted position 98 and the second plunger 94 is located in the second extended position 100.
Referring to
The patient may now take the depleted pharmaceutical dispenser 10 to the clinic to be replenished. In this regard the sub-lid assembly 38 includes a communication coil 106, shown in
Referring to
Should the pharmaceutical dispenser 10 become defective, for example due to a mechanical or electrical failure preventing a clinic to detach the lid 14 from the base 12, it is desirable that a manual override mechanism be provided. In this regard the pharmaceutical dispenser 10 includes a cap 120, shown in
Removing the cap 120 from the sub-lid base 114 exposes a key opening 130 though which a key 132 is permitted to pass. The key 132 is operatively adapted to engage a key lever 134 which is attached to the actuating lever 52. The key lever 134 is configured so that an upward force applied by the key 132 to the key lever 134 will move the actuating lever 52 from the actuator engage position 62, shown in
