Abstract
The invention relates to a spray cap for aerosol containers comprising an integrally formed housing (1) comprising an actuating button (2) and an actuating lever (3), both flexibly connected to the housing (1). The actuating button (2) has a drive hook (18), which moves into interaction with a drive projection (19) disposed on the actuating lever (3) when the actuating button (2) is firstly moved radially and then axially. Due to the combined movements required for actuating the aerosol container, unauthorised use is to the greatest extent excluded. The actuating button (2) and actuating lever (3) are so designed that, via a recess (16) provided in the actuating button (2), the latter can be moved axially downwards without the drive hook (18) engaging with the drive projection (19) of the actuating lever.
Claims8
A spray cap for an aerosol container including a valve tube, said spray cap and said container having a common axis, said spray cap comprising
- a housing (1) having an outer wall (13), an actuating lever (3) having a tubular projection (5) extending along the axis of the housing and container, said projection being constructed and configured for connection to said valve tube of the aerosol container, a nozzle (8) for discharging the aerosol contents and said lever (3) having a feed channel (7) connected to said nozzle (8) at one end and to said tubular projection (5) at the other end for discharging the contents of the container,
- said actuating lever (3) being integrally formed with the housing (1) and including a first hinge connection (11a) with said outer wall (13) of the housing (1), the feed channel (7) extending radially with respect to the container axis and axially displaced from the first hinge connection (11a) away from the container,
- an actuating button (2), a second hinge connection (11) integrally formed with the button and the wall (13) of the housing (1) and said button (2) being pivotally mounted thereby to move radially and axially of said container,
- the improvement wherein
- said actuating button (2) being spaced radially from said actuating lever and located to freely pass the actuating lever (3) when moved axially toward the container, said second hinge connection (11) being configured and constructed for radial movement of the actuating button (2) with a pivotal movement towards the container, said actuating lever being mounted in the path of said pivotal movement and engaged by said radial and pivotal movement of the button whereupon the actuating button (2) engages the actuating lever (3) to pivot same toward the container about the first hinge connection (11a).
