Secure dispensing apparatus is described which is adapted to dispense e.g. a prescription drug from an axial compression dispensing device (1). This is located in a housing (10) including a dispensing aperture (16). The axial compression dispensing device (1) is located in a central chamber of axial length slightly longer than that of the axial compression dispensing device, and structures (30) are provided at one end of the chamber movable with respect thereto to compress the axial compression dispensing device to cause dispensing via the dispensing aperture (16). The structures (30) comprises a central breakable axial stem (33) attached to a pressure plate (34), the pressure plate having a surface configuration on its side facing away from the axial compression dispensing device providing a set of surfaces (35) not in a plane transverse to the axis of the breakable stem, and apertures (36) in the end of the outer housing aligned with the set of surfaces of the pressure plate and none of the apertures (36) being coaxial with the breakable stem (33). Structures such as a wall (15) are provided to limit the amount of movement of the pressure plate (34) away from the end (11) of the outer housing containing the set of apertures (36).

1. A secure dispensing apparatus which comprises a dispensing device surrounded by a housing, the housing having an aperture registered with a dispensing aperture of the dispensing device, and the dispensing device being actuatable to dispense a dose of material contained within it by a rectilinear movement of an actuation member relative to the housing and acting upon a part of the dispensing device, and wherein between the actuation member and the part of the dispensing device there is located a force-transmitting member having at least one elongate breakable stem located substantially parallel to the direction of movement of the actuation member, and the stem(s) being connected to a pressure plate having a surface configuration on its side facing away from the stem providing a set of surfaces not in a plane transverse to the axis of the stem, and wherein the housing has a set of apertures aligned with the set of surfaces on the pressure plate and means for limiting the amount of movement of the force-transmitting member.2. The apparatus according to claim 1 wherein the dispensing device is an elongate or discoid container or cassette from which a quantity or unit of material can be dispensed by axial or rotary movement.3. The apparatus according to claim 1 wherein the breakable stem is a single breakable stem, and wherein the number of apertures in the set of apertures in the housing is 5 to 7 and wherein the apertures are substantially equiangularly spaced around an axis of the single breakable stem.4. The apparatus according to claim 3 wherein the apertures are substantially equidistant from the axis of the stem in a radial direction.5. The apparatus according to claim 3, wherein the apertures are of at least two different shapes.6. The apparatus according to claim 1 wherein the set of apertures in the housing is covered with a frangible seal.7. A secure dispensing apparatus which comprises an axial compression dispensing device surrounded by a housing, the housing having an aperture registered with a dispensing aperture of the axial compression dispensing device, and having a central chamber surrounding the axial compression dispensing device and of axial length slightly longer than that of the axial compression dispensing device, and means at one end of the chamber movable with respect thereto to compress an axial compression dispensing device located within the chamber, whereby to cause dispensing via the dispensing aperture, wherein the means comprises a central breakable axial stem attached to a pressure plate, the pressure plate having a surface configuration on its side facing away from the axial compression dispensing device providing a set of surfaces not in a plane transverse to the axis of the breakable stem, and a set of apertures in the end of the housing aligned with the set of surfaces of the pressure plate and none of the apertures being coaxial with the breakable stem, and wherein means are provided to limit the amount of movement of the pressure plate away from the end of the outer housing containing the set of apertures.8. The apparatus according to claim 7 wherein the central breakable axial stem is a single breakable stem, and wherein the number of apertures in the set of apertures in the housing is 5 to 7 and wherein the apertures are substantially equiangularly spaced around an axis of the single breakable stem.9. The apparatus according to claim 8 wherein the apertures are substantially equidistant from the axis of the stem in a radial direction.10. The apparatus according to claim 8 wherein the apertures are of at least two different shapes.11. The apparatus according to claim 7 wherein the set of apertures in the housing is covered with a frangible seal.12. A secure dispensing apparatus comprising:(a) a housing constructed and arranged to surround a dispensing device, the housing including a housing aperture registerable with a dispensing aperture of the dispensing device, and having at least one key aperture constructed and arranged to accept an authorized key; (b) an actuation member, moveable relative to the housing in a rectilinear direction and constructed and arranged to cooperate with a part of the dispensing device to permit the dispensing device to dispense a dose of material contained within it; (c) a force-transmitting member constructed and arranged to be located proximate to said part of the dispensing device, the force-transmitting member including at least one elongate breakable stem positioned substantially parallel to the direction of movement of the actuation member, the stem being connected to a pressure plate having a surface configuration on a side facing away from the stem and facing the at least one key aperture in the housing, the pressure plate being aligned with the at least one key aperture in the housing allowing an inserted authorized key to contact the surface configuration of the pressure plate, the force-transmitting member moving in response to a pressure from the authorized key to permit dispensing from the dispensing device. 13. The apparatus according to claim 12, wherein the force-transmitting member is constructed and arranged to be located between the actuation member and said part of the dispensing device.14. The apparatus according to claim 12, wherein the surface configuration provides a set of surfaces.15. The apparatus according to claim 14, wherein the set of surfaces are not in a plane transverse to the axis of the stem.16. The apparatus according to claim 12, in combination with the dispensing device, the dispensing device being an elongate or discoid container or cassette from which a quantity or unit of material can be dispensed by axial or rotary movement.17. The apparatus according to claim 12, wherein the at least one key aperture includes a set of key apertures.18. The apparatus according to claim 17 wherein the breakable stem is a single breakable stem, and the number of apertures in the set of key apertures in the housing is 5 to 7 and wherein the apertures are substantially equiangularly spaced around the axis of the single breakable stem.19.
