In Figs. 1 and 2 is shown an aerosol dispensing device embodied as an aerosol cap 1 which is mounted on an aerosol container 100. Fig. 3 shows the cap 1 from below when it is not placed on the container.
The aerosol container 100 may typically be a substantially cylindrical metal (usually aluminium) can having an opening at a top end which is sealed by a valve cup 102. The valve cup 102 is attached to the container by a crimping connection. The valve cup 102 holds a valve assembly which includes a valve stem 101. The aerosol container may be an aerosol container that contain a product, e.g. a fluid, to be dispensed and a propellant gas mixed with the product to expel the product out of the container when the valve of the valve assembly is opened. Also other types of aerosol containers are possible, for example bag-on-valve type containers, in which the product to be dispensed, e.g. a fluid, is contained in a bag, which is arranged inside the container. The container around the bag is pressurized with compressed gas, e.g. air or nitrogen as propellant. The valve stem 101 is able to operate the valve when it is pushed in or sideways, such that the valve opens and the product, e.g. a fluid, is expelled from the container by a propellant gas. The valve stem 101 is a tubular member through which the fluid will flow. The valve stem may be the valve stem of a so called male valve, as is shown in Fig. 2, as well as of a female valve, which is well known for the person skilled in the art. The valve stem will in many applications be connected to a spray nozzle which forms the flowing fluid into a spray. The spray nozzle is often comprised in an aerosol spray cap.
The aerosol cap 1 comprises two main components: a cap body 2 and an actuator 3 which is moveable with respect to the cap body 2.
The cap body 2 comprises a circumferential wall 4 which defines an open end 5 at a bottom end of the body 2. Near the open end 5 the circumferential wall 4 has beads 6 (cf. Fig. 3) or other protrusions which can snap behind a ridge 103 of the container 100. The ridge 103 of the container can for example be formed by the crimped connection of the valve disc 102 connected to the spray can 100. Once the cap body 2 is snapped on the aerosol container, the cap body 2 of this particular embodiment cannot be pulled of the container again without the use of undue force.
The actuator 3 comprises a push button 7 and a flow channel 8 that is, at least in the shown embodiment, integrally formed on an underside of the push button 7. The flow channel 8 has an inlet end 8A which is colinear with the central axis of the cap body 2 of the aerosol cap 1.
In the embodiment shown, the flow channel 8 has two perpendicular portions 8B and 8C adjoining each other. The inlet end 8A located at the end of the portion 8B of the flow channel 8 is suitable to be connected with the valve stem 101 of the aerosol container. When in use the push button 7 is pushed in, the flow channel 8 will be pushed towards the aerosol container whereby the valve stem 101 is pushed in. This opens the valve and content of the pressurized aerosol container 100 is ejected into the flow channel 8 at the inlet end 8A.
The flow channel 8 has an outlet end 8D. At the outlet end 8D a nozzle head 9 is formed as is best visible in Figs. 4-6. The nozzle head 9 has a central post 18 and a circumferential wall 19 concentrically surrounding the central post 18. The central post 18 and the circumferential wall 19 define between them an annular chamber 20. The central post 18 has a flat end surface 21 at which the outlet of the flow channel 8 is located.
As can be seen in Fig. 4, the embodiment shown has a groove like flow channel outlet end 8D formed in the upper side of the post 18. In another possible embodiment, the outlet end may be a closed channel coaxial with the centre axis of the post 18.
Anozzle insert 10 is positioned in the actuator 3 at the nozzle head 9. The present invention proposes to assemble the aerosol device, in particular the aerosol dispensing cap with different types of nozzle inserts.
In particular it is proposed to provide a range of nozzle insert types, said range comprising at least two of the following nozzle insert types: a spray dispensing nozzle insert; a gel dispensing nozzle insert; and a foam dispensing nozzle insert. An embodiment of a foam dispensing nozzle insert is shown in Figs 7-13. An embodiment of a gel dispensing nozzle insert is shown in Figs 14-20. An embodiment of a spray dispensing nozzle insert is shown in
Figs 21-26.
Depending on the product to be dispensed, the common aerosol actuator 3 can be assembled with a specific type of nozzle insert which makes the aerosol dispensing cap suitable for dispensing the specific product. positioning the nozzle insert in the receiving chamber of the nozzle head of the actuator.
If the aerosol dispensing cap has to be suitable for dispensing spray from an aerosol container, the insert of Figs 21-26 can be used. The spray dispensing nozzle insert is indicated by reference numeral 400.
The spray nozzle insert 400 comprises an end wall 411 having a spray orifice 412 therethrough. The end wall 411 has an outer side 411A and an inner side 411B. A cylindrical wall 413 connected to the inner side 411B of the end wall 411 surrounds the spray orifice 412 and is arranged concentrically with the spray orifice 412.
The end wall 411 of the spray nozzle insert 400 has substantially an oblong shape, which is best seen in Figs. 25 and 26. Snap fingers 414 extend from opposite smaller sides of the oblong shape. In this embodiment the snap fingers 414 have the same width as the smaller sides of the oblong end wall 411.
The snap fingers 414 are located at a radial distance outside the cylindrical wall 413. Each snap finger 414 has a snap member 415 which is able to hook behind a complementary hooking edge in the actuator 3.
The actuator 3 has at least two first guiding ribs 30 spaced apart from an outer side of the circumferential wall 19 of the nozzle head 9 configured to guide each snap finger 414 upon positioning the spray nozzle insert 400 in the actuator 3. Each snap finger 414 has a snap member 415 which, in a fully inserted state, is snapped behind an inward end 31 of the first guiding rib 30. The inward end 31 of the first guiding rib 30 is thus the aforementioned complementary hooking edge.
The spray nozzle insert 400 is positioned in the actuator 3, wherein the cylindrical wall 413 of the spray nozzle 400 insert is located in the annular chamber 20 of the nozzle head 9. The flat end surface 21 of the central post 18 is in abutment with a portion of the inner side 411B of the end wall 411 that is situated within the contour of the cylindrical wall 413.
The aerosol cap 1 can be provided in the same way as outlined in the above with a foam dispensing nozzle insert 200 shown in Figs. 7-13.
The foam dispensing nozzle insert 200 comprises an end wall 211 having an orifice 212 therethrough. The end wall 211 has an outer side 211A and an inner side 211B. A cylindrical wall 213 is connected to the inner side 211B of the end wall and surrounds the orifice 212. A circumferential wall 216 connected to the outer side 211A of the end wall 211 is arranged such that the orifice 212 is located within the perimeter of the circumferential wall 216. The circumferential wall has a generally oblong, more or less rectangular shape. In the specific embodiment shown, the long sides 216A of the rectangle are curved, such that the outer side thereof is convex, which is best seen in Fig.11. The short sides 216B are straight. Parallel partition walls 217 are formed within the perimeter of the circumferential wall 216. The partition walls 217 each have ends 217A that are connected to the circumferential wall 218.
The partition walls 217 define foam expansion chambers 218 with the circumferential wall 216 and the end wall 211. The foam expansion chambers 218 are open on a side remote from the end wall 211. The orifice 212 is in communication with each one of the foam expansion chambers 218.
The foam dispensing nozzle insert 200 is positioned in the actuator 3, in the same way as the spray nozzle insert 400 is positioned in the actuator. The cylindrical wall 213 of the foam dispensing nozzle insert 200 is located in the annular chamber 20 of the nozzle head 9 (cf.
Fig. 4). The flat end surface 21 of the central post 18 is in abutment with the inner side 211B of the end wall 211 of the foam dispensing nozzle insert 200.
The foam dispensing nozzle insert 200 has at least two snap fingers 214 located at a radial distance outside the cylindrical wall 213. The snap fingers 214 extend from the inner side of the end wall 211. The actuator 3 has the guiding ribs 30 spaced apart from an outer side of the circumferential wall 19 of the nozzle head 9 as described already in the above. The guiding ribs 30 are configured to guide each snap finger 214 upon positioning the nozzle insert 200 in the actuator 3. The snap finger 214 has a snap member 215 which is snapped behind the inward end 31 of the guiding rib 30 in a fully inserted state.
The orifice 212 is formed as a slot in the end wall 211. The slot extends through the wall within the perimeter of the cylindrical wall 213. In the outer side 211A of the end wall 211 groove-shaped extensions 219 of the through slot 212 are formed. The slot 212 and the groove extensions 219 extend in a direction transverse, in particular perpendicular to the partition walls 217. The slot 212 is in communication with each of the expansion chambers 218.as can be best seen in Fig. 11.
When foam is dispensed through the flow channel 8 in the central post 18, the foam will be distributed in the slot 212 and the groove extensions 219 of the slot 212. The walls 217 which cross the slot 212 will prevent a direct flow locally and facilitates the foam distribution into the slot 212 and groove expansions 219 and therethrough into the foam expansion chambers 218. The expansion chambers 218 are filled with the expanding foam and will be expelled from the expansion chambers 218. In the embodiment shown in the figures, there are two partition walls 217 thus providing three expansion chambers 218. The respective flows of foam flowing out of the respective expansion chambers 218 join each other outside the expansion chambers 218, remote of the end wall 211 of the foam dispensing nozzle insert 200. The foam partially flows from the slot 212 into the rear side of the partition walls 217 (see
Fig. 10), which creates a resistance. Also the expansion chambers 219 create a resistance for the flow of foam. By theses resistances a better quality of foam is achieved.
The aerosol cap 1 can be provided in the same way with a gel dispensing nozzle insert 300 shown in Figs.14-20.
The gel dispensing nozzle insert 300 comprises an end wall 311 having an orifice 312 therethrough. The orifice 312 has an elongate, preferably round, shape, in particular an oval or elliptic shape. The end wall 311 has an outer side 311A and an inner side 311B. A first cylindrical wall 313 connected to the inner side 311B of the end wall 311 is arranged around the orifice 312, in particular concentric with the orifice 312. A second cylindrical wall 316,
which is connected to the outer side 311A of the end wall 311, is arranged concentric with the orifice 312.
The gel dispensing nozzle insert 300 is positioned in the actuator 3 in the same way as the spray nozzle insert 400 is positioned in the actuator 3. The first cylindrical wall 313 of the gel dispensing nozzle insert 300 is located in the annular chamber 20 of the nozzle head 9. The flat end surface 21 of the central post 18 is in abutment with the inner side of the end wall 311 of the nozzle insert 300 within the perimeter of the wall 313, which is indicated by reference numeral 311C. There are thus two contact surfaces 311 which contact the end surface 21 of the central post 18. Between the contact surfaces 311C a recess 311D is formed on either end of the elliptic or oval shape. The recesses 311D provide additional space for the gel that is dispensed and that expands when it flows out of the dispensing channel 8.
The gel dispensing nozzle insert 300 has at least two snap fingers 314 located at a radial distance outside the first cylindrical wall 313. The snap fingers 314 extend from the inner side 311B of the end wall 311. The actuator 3 has the guiding ribs 30 spaced apart from an outer side of the circumferential wall 19 of the nozzle head 9 as described already in the above.
The guiding ribs 30 are configured to guide each snap finger 314 upon positioning the nozzle insert 300 in the actuator 3. The snap finger 314 has a snap member 315 which is snapped behind the inward end 31 of the guiding rib 30 in a fully inserted state.
The aerosol caps 1 that are produced by assembling the common actuator 3 and the different nozzle inserts 200, 300, 400, which are described in the above, are preferably well recyclable.
In order to allow for good recyclability, the aerosol caps are preferably entirely made from the same material, or at least from compatible materials. In particular the aerosol caps 1 are made by injection moulding one or more parts from the same plastic material. Preferably the cap 1 including the nozzle insert 200, 300, 400 of one of the above-described types is made of a suitable polypropylene (PP) blend. The nozzle inserts 200, 300, 400 can thus be made in an injection moulding process using a PP blend. The other parts of the cap 1, i.e. the cap body 2 and the actuator 3 can be made in one piece in an injection moulding process, or can be made separately by injection moulding and then assembled. Also for the cap body 2 and the actuator a polypropylene (PP) is a suitable material.
The aerosol caps 1 provided with one of the respective nozzle inserts 200, 300, 400 are placed on an aerosol container containing the corresponding substance, i.e. foam, gel or spray forming liquid.
A particular application for a foam dispensing aerosol cap 1 as described in the above can be assembled with a pressurized container which contains a foam forming substance, which is dispensed as a foam, which foam is for personal care such as for example shaving foam, haircare foam, body care foam, e.g. shower foam.
A particular application for a gel dispensing aerosol cap 1 as described in the above can be assembled with a pressurized container which contains a gel forming substance, which is dispensed as a gel, which gel is for personal care such as for example shaving gel, shower gel or hair gel
