• Openings 28 are provided at opposite sides of the cup 18 in a bottom part of the base section 14.
• the openings 28 are provided to allow the possibility of a user grasping the base section 14 to allow its disengagement from the upper section 12, as will be described below. Also, the openings 28 are used during a moulding process for forming the horizontal lower face of the wedge-shaped beads 24 a, b.

• the upper section 12 of the spraying device 10 has a generally bell-shaped outer wall 34 with a slightly concave top surface 36, in the centre of which is an outlet opening 38 in the centre thereof.
• a sleeve 40 projects downwards from the concave top surface 36 through the interior of the upper section 12.
• the sleeve 40 is designed to engage with the vertical projections 22a,b of the base section 14.
• the sleeve is generally cylindrical in shape.
• the slits 42 have a length of approximately 6.5mm, which creates the length of the tabs 44.
• the bead 46 is intended to engage with the wedge-shaped beads 24a,b on the vertical projections 22a,b of the base section 14.
• the presence of the slits 42 allows flexure of the tabs 44 to allow outward movement thereof during engagement with and release from the wedge-shaped beads 24a,b of the base section 14, as described in more detail below.
• ribs 48 which project radially towards the centre of the sleeve 40.
• the ribs 48 provide a centralising guide for a boss section 51 of the aerosol canister 16.
• Lower ends of the ribs 48 are tapered slightly to allow easier guiding of the sleeve 40 over the aerosol canister 16 and to avoid engagement with a shoulder section 50 of the aerosol canister 16.
• a collar 52 which extends downwardly into the interior of the upper section 12.
• the collar 52 has an internal shoulder 54 against which a stem 56 of the aerosol canister 16 is engaged to depress a spring valve in the aerosol canister in order to cause discharge of the contents of the aerosol canister 16 in the usual way.
• a lower edge 58 of the collar 52 has a chamfer in order to ease engagement of the stem 56 with the collar 52.
• Strengthening ribs 60 are provided between the sleeve 40 and an inside of the bell-shaped outer wall 34 in order to provide greater stability and strength of the sleeve 40 with respect to the outer wall 34.
• a user places the aerosol canister 16 in the cup 18 of the base section.
• the user then places the upper section 12 onto the over the aerosol 16.
• the stem 56 of the aerosol canister 16 is guided into the collar 52, because of engagement of the boss section 51 of the aerosol canister with the ribs 48 of the upper section 12.
• the user can push the upper section 12 further onto the base section 14 to lock the two parts together and to cause activation of the aerosol canister 16 and so cause the contents of the aerosol canister to be discharged from the opening 38 in the upper section 12.
• the upper section 12 is locked onto the base section 14 by- means of engagement of the vertical projections 22a,b of the base section 14 and the tabs 44 of the upper section 12.
• Each of these parts has a bead as discussed above and the two beads engage one another to lock the upper section 12 to the base section 14.
• the relative lengths of the vertical projections 22a,b and the sleeve 40 with its tabs 44 at the base thereof is chosen to ensure that the aerosol canister 16 is activated when the upper section 12 is locked to the base section 14.
• the locking of the two together causes the entire contents of the aerosol canister to be discharged, because the aerosol canister has a continuous spray valve.
• a user would typically leave a room in which the spraying device 10 has been placed during discharge of the spraying device.
• the spraying device 10 can be removed.
• the user pulls the upper section 12 away from the base section 14, potentially by using the openings 28 in the base section 14.
• the aerosol canister 16 remains in the upper section 12, because that part has a stronger interference fit between the aerosol stem 56 and the internal collar 52 of the upper section 12, compared to the interference fit between the aerosol canister 16 and the base section 14. Consequently, the base of the aerosol canister 16 protrudes from the upper section 12, from which position it can easily be removed by a user for replacement by a full aerosol canister 16 for subsequent dispensing of material held within the aerosol canister 16.
• the length of the slits 42 is a significant factor in relation to the strength of locking between the upper section 12 and the base section 14. If the slits are too short, making flexure of the tabs 44 less pronounced, then a user will have much greater difficulty in pushing the upper section 12 down onto the base section 14 to create a lock between the two parts. Also, there will be much greater resistance to separation of the two parts after the aerosol canister 16 has been discharged. However, if the slits 42 are too long (meaning greater flexure of the tabs 44) then there will be insufficient locking action between the upper section 12 and the base section 14, such that the force of the spring valve in the stem 56 of the aerosol canister 16 will push the upper section 12 away from the base section 14.
• the amount of flexure in the tabs 44 is particularly significant to the proper working of the spraying device 10.
• the length of the slits of 7mm bearing in mind the flexibility of plastic materials typically used for such a device, is found to be particularly beneficial.
• the bead 46 is spaced approximately 3mm from the end of the slits 42. The bead must be on the tabs 44, to allow flexure thereof.
• the vertical projections 22a,b also flex at their top ends close to the wedge-shaped beads 24a,b.
• This flexure is caused by the ribs 26a and 26b extending only part way up the vertical projections 22a,b.
• the beads 24a,b bear against the aerosol canister 16 held in the cup 18.
• This flexure allows greater movement of the wedge-shaped beads 24a,b towards the aerosol canister to allow engagement of the wedge-shaped bead 24a,b with the bead 46 incorporated into the tabs 44 of the upper section.
• a delaying device to delay issue of material from the aerosol canister may be provided.
• Said delaying device may be in the form of a blockage in the stem 56, which blockage is cleared by pressure from the contents of the canister 16.
• the design described herein is advantageous in that the aerosol canister 16 is held in a vertical orientation by use of the four ribs 20a-20d in the base section 14. Further support for the aerosol canister in a vertical orientation is provided by the ribs 26a,b.
• flexure of the beads 24a,b and 46 of the upper section 12 and base section 14 respectively is particularly significant for ease of use of the spraying device 10. Flexure is needed to allow for the beads to pass one another as the two parts are engaged or disengaged.
• the advantage that follows from the above is that the device can easily be used with replacement aerosol canisters when a first canister has been discharged.
