Abstract
The present invention relates to dispensing apparatus comprising a housing (10) for receiving a pressurised container (15) containing product for dispensation, series of markings (172) indicative of quantities of product in the container, indicator means (160; 200) for indicating one of the markings of the series, and means for effecting relative movement between the indicator means and the series of markings on actuation of the pressurised container, so as to designate a subsequent marking of the series.

Dispensing apparatus comprising a housing (10) for receiving a pressurised container (15) containing product for dispensation, a series of markings (172) indicative of quantities of product in the container and indicator means (160;
- 200) for indicating one of the markings of the series, characterised in that a cylindrical member (140) is located in the housing (10), one of the housing and the cylindrical member being provided with a longitudinal slot (170) and the other of the housing and the cylindrical member having a helical channel (141) along its longitudinal axis, the indicator means (160;
- 200) being operatively connected to both the longitudinal slot and helical channel such that rotation of the cylindrical member relative to the housing on actuation of the pressurised container moves the indicator means along the longitudinal axis of the cylindrical member so as to designate a subsequent marking of the series.
Dispensing apparatus comprising a housing (10) for receiving a pressurised container (15) containing product for dispensation, a series of markings (172) indicative of quantities of product in the container and indicator means (160, 200) for indicating one of the markings of the series, characterised in that one of the housing and the pressurised container (15) is provid d with a longitudinal sl t (170) and the other of the housing and the pressurised container is provided with a helical channel (141) along its longitudinal axis, the indicator means (160;
- 200) being operatively connected to both the longitudinal slot and helical channel such that rotation of the pressurised container relative to the housing on actuation of the pressurised container moves the indicator means along the longitudinal axis of the housing.
Dispensing apparatus comprising a housing (10) for receiving a pressurised container (15) containing product for dispensation, a series of markings (172) indicative of quantities of product in the container and indicator means (160, 200) for indicating one of the markings of the series, characterised in that the housing is provided with a helical channel (141) along its longitudinal axis and a collar (155), the indicator means (160, 200) being operatively connected to the helical channel (141) and the collar (155) such that rotation of the collar (155) relative to the housing on actuation f the pressurised container moves the indicator means along the longitudinal axis of the housing.
Dispensing apparatus comprising a housing (10) for receiving a pressurised container (15) containing product for dispensation, a series of markings (172) indicative of quantities of product in the container and indicator means (160, 200) for indicating one of the markings of the series characterised in that the housing (10) comprises a longitudinal slot (170) and the series of markings (172) are provided in a helical arrangement around the pressurised container (15) or other member (140;
- 155) located in the housing, such that only one of the series of markings is visible through the slot at any one time.
