  • the retaining member 456 When the cover mechanism 400 is in the closed position, the retaining member 456 is received in the closed position recess 462. Force applied to the cover mechanism 400 in a clockwise direction is resisted by the ends of the cam slots 434 acting as motion limiting stops. If a small amount of force, such as may result from unintentional contact with the actuating member 420, is applied to the cover mechanism 400 in a counter-clockwise direction, it is resisted by the biasing of the retaining member 456 against the edges 454a, 454b of the channel 454. The cover mechanism 400 is therefore retained in the closed position.
  • the retaining member 456 slides along the channel 454 and moves in a radially inwards direction, against the biasing.
  • the spring of the ball spring arrangement is compressed.
  • the retaining member 456 travels in the channel 454 towards the mid region of the channel 454.
  • the retaining mechanism 450 is therefore releasable by the user moving the actuating member 420 out of the closed position.
  • the cover mechanism 400 ceases to be biased towards the closed position and begins to be biased towards the first open position.
  • the spring of the ball spring arrangement is maximally compressed.
  • the force exerted by the retaining member 456 in a radially outwards direction relative to the axis of rotation of the actuating member 420 is therefore at a maximum.
  • the first edge and second edge 454a, 454b reach a point of maximum convergence.
  • the mid region of the channel represents an inflection point of the first edge and second edge 454a, 454b.
  • the force exerted by the retaining member 456 in the radially outwards direction therefore does not result in biasing of the cover mechanism 401.
  • the retaining mechanism 450 is therefore biased into the closed position over a portion of its range of motion adjacent to the closed position.
  • the retaining mechanism 450 is biased into the closed position over substantially 50% of the first range of motion adjacent to the open position.
  • the retaining mechanism 450 is biased into the open position over a portion of its range of motion adjacent to the open position.
  • the retaining mechanism 450 is biased into the open position over substantially 50% of the first range of motion adjacent to the open position.
  • the retaining mechanism 450 is therefore biased over substantially the entire first range of motion.
  • the only point at which the retaining mechanism 450 is unbiased is a the exact mid-point of the first range of motion. It will be understood that the mid-point is not necessarily exactly half way through the first range of motion, but may be.
  • the cover mechanism 400 therefore returns to the closed position after small deflections, reducing the likelihood of inadvertently opening or partially opening the cover mechanism 400.
  • the time taken to move the cover mechanism 400 between the open position and the closed position may therefore be minimised, and the effort required by the user may also be reduced.
  • the retaining mechanism 450 comprises a second channel 455 extending between the first open position recess 460 and the second open position recess 464.
  • the features and operation of the second channel 455 are generally equivalent to those of the first channel 454.
  • the cover mechanism 400 has been described with relation to one retaining member 456 and three recesses 460, 462, 464.
  • the cover mechanism 400 of Figures 3 to 7 comprises two retaining members 456, two first open position recesses 460, two second open position recesses 464 and two closed position recesses 462.
  • the operation of the second retaining member 456, first and second open position recess 460, 464 and closed position recess 462 is generally equivalent to that described above.
  • a different number of retaining members, open position recesses and closed position recesses is used.
  • a single recess may operate as a closed position recess in relation to one retaining member and as an open position recess in relation to another retaining member. That is, the ratio of recesses to retaining members may differ from two to one.
  • the cam mechanism is omitted and the actuating member 420 is connected to the cover member 410 by a gear mechanism acting as a drive mechanism.
  • the actuating member 420 may comprise a gear track on an inner or outer surface of the actuating member 420.
  • the cover mechanism 401 may comprise a gear arranged to be driven by the gear track and rotatably mounted on the body 410.
  • the cover member 410 may comprise a gear track arranged to be driven by the gear.
  • the cover member 410 is arranged to translate linearly on the body 402, responsive to rotation of the cover member 420.
  • the first range of motion and the second range of motion may therefore be linear.

Abstract

L'invention concerne un dispositif de fourniture d'aérosol (100) qui comprend un corps (101) comprenant une ouverture (103) et une chambre (105) dans le corps agencée pour recevoir au moins une partie d'un article (300) comprenant un matériau de génération d'aérosol à travers l'ouverture. Le dispositif comprend un mécanisme de couvercle (401) comprenant un élément de couvercle (410) agencé pour recouvrir sélectivement au moins partiellement l'ouverture et un élément d'actionnement (420) agencé pour se déplacer par rapport au corps. Le mouvement de l'élément d'actionnement par rapport au corps dans une première plage de mouvement amène l'élément de couvercle à effectuer une translation entre une position relativement ouverte dans laquelle ladite au moins une partie d'un article peut passer à travers l'ouverture et une position relativement fermée dans laquelle ladite au moins une partie d'un article ne peut pas passer à travers l'ouverture.
