Embodiment Construction

[0054] figure 1 Denotes a dispensing device generally indicated by reference numeral 1, having an upper body 3, a lower body 5 and Figure 8 The detachable nozzle 20 is shown. Spout 20 may be covered with a dust cap when the device is not in use. Such as figure 2 As shown, the dispensing device is also provided with first and second counting rings 11 , 13 , a gear 12 and a sleeve 100 . In use, the device receives a pressure dispensing container 10 .

[0055] The lower body 5 is open at its upper end. The lower body 5 houses a gear 12 and a first and a second counting ring 11 , 13 . Such as image 3 Shown in more detail, the counting rings 11 , 13 are seated on inner projections 111 of the main body 5 . The inner protrusion 111 is provided with an upwardly facing surface on which the second counting ring 13 can be seated and rotated during use. The first counting ring 11 is seated on top of the second counting ring 13 and rotates thereon during use. The gear 12 is rot...

Abstract

The present invention provides improvements in or relating to dispensing apparatus dispensing apparatus for delivering metered doses of product from a pressurised dispensing container comprising: a housing comprising a body portion and a removable mouthpiece, the body portion containing a dose counting mechanism and a sleeve; the body portion comprising an aperture through which said pressurised dispensing container can pass to be received in the sleeve but through which the sleeve is unable to pass such that the sleeve is retained within the body portion; the sleeve being located in the bodyportion such that an upper end of said pressurised dispensing container when received in the sleeve is accessible to allow actuation of said pressurised dispensing container; the apparatus comprisingmeans for retaining said pressurised dispensing container in the body portion.

Description

technical field [0001] The present invention relates to a dispensing device having an integral dose counter requiring axial force actuation. Background technique [0002] It is recognized that there is a need to provide users of dose dispensing delivery devices, such as pressurized metered dose inhalers, with accurate information concerning the number of doses delivered from the dispensing device or the number of doses remaining in the dispensing device. Without such information, there is a risk that the user may forget how many doses have been delivered and thus withdraw more or fewer doses than required. There is also the danger that the user may not be aware that the dispensing container of the dispensing device is empty or nearly empty. This is particularly dangerous when the dispensing device is used to deliver medicinal compounds for the treatment of chronic or acute conditions, for example, in the case of pressurized metered dose inhalers for the treatment of asthmat...
