The present technology relates generally to candles. The present technology also relates generally to candle making apparatus and methods of making candles. In addition, the present technology relates generally to fuel elements and fuel assemblies for feeding candle making apparatus and for use in methods of making candles.
Candles enjoy enduring popularity. This is so, even though newer technologies such as incandescent bulbs, halogen lamps, fluorescent lamps, and LED lamps have been developed to increase the efficiency of delivery of light.
Candles do not merely provide light; the way it is delivered acts on human senses to facilitate different moods. The flickering of light from the wick moves people in different ways and can evoke certain primal feelings, among them: peace, happiness, relaxation, safety, romance and warmth. Candles can also facilitate meditation and solemnity. A flickering LED light, while passably more pleasant than a static LED light, is often described as fake and unsatisfying.
A scent may be added to the fuel so that an additional sense is involved in the experience.
Candles are also very practical, since they can provide light in emergency situations where electrical and battery power is temporarily unavailable.
For these reasons and more, many people enjoy making their own candles.
Candlemaking apparatus are known, but they are messy and time consuming to use. Making a single candle can take hours, since the fuel, in the form of wax flakes, must be very carefully loaded into a melting reservoir portion of the apparatus. Nevertheless, it usually spills around the apparatus, which takes further time to clean up.
Finally, some candle fuel is not clean burning, and/or is scented in a way that they were not expecting; customers like to know the provenance of their products.
The present inventor seeks to provide a candle making apparatus and a method of making a candle, and a fuel element for loading the candle making apparatus which substantially ameliorate one or more of the above mentioned disadvantages and/or which at least provides a useful alternative to known candle making apparatus, methods and fuel.
TAPER: throughout this specification and the claims that follow, it is to be understood that the word “taper” takes its plain meaning, which is, a slender candle. It is to be understood that the taper includes a wick which could itself be substantially rigid or flexible, which is combustible, including braided cotton, fabric, wood, bark, skewer, or suitable combustible material.
Fuel plug: throughout this specification and the claims that follow, it is to be understood that the word “scented fuel plug” is to be understood as a fuel element, like a taper, but which may not have a wick disposed in a central axial position thereon.

Advantageously, embodiments of the present technology provide a way of assembling a candle where one or more scented tapers are placed in a through hole in a pillar of fuel.
During assembly, users are not exposed to heat or pressure, or molten wax, or mess. Assembly time is measured in seconds, rather than hours.
A person could come home from work, select a scented taper, say, lemon myrtle, Port Jackson fig, gardenia, or a blend of two tapers with two or more of these scented units, place it or them in the taper loader, and close the drawer. The user then loads a container, if desired, into the container loading zone, and presses the actuator button. The candle is assembled in a few seconds or a minute or so, and is ready to remove from the assembly zone. The candle is then ready to use.
Users can also have confidence that the fuel they are burning is of a selected quality since in some embodiments the machine checks the barcodes or chips on the fuel fuel and even the container if required. The utility of the container being checked for quality is that the container is less likely to break during heating by the fuel load, and the fingers are unlikely to be burnt, since the container quality control will be carefully monitored.

A control system 70 that includes a processor 72 is disposed in the housing 60 to control aspects of the assembly process described below.
The apparatus 10, 110 further includes a loader 50 for loading a taper 9 into the fuel stack 8 in the assembly zone 40. An alternative embodiment shown does not include a loader 50. When there is no wax cutter, the dispenser 30 is configured to work with a stack of wax pucks 4, which may have integral tapers 9, which can be merely dropped or dispensed from the reservoir in operation and stacked in the assembly/loading zone in operation, or the builder may include a wax cutter 90 to form one or more smaller fuel elements 5 or pucks 4 for the dispenser 30 to drop into the assembly zone.
Fuel is in the form of fuel elements 5 and in the form shown, each fuel element 5 includes one or more debossed and/or embossed surface portions 7 configured to cooperate with other like fuel elements 5 when one is stacked atop another (cf
There may be pucks 4 provided, which include a skin 2, which may be a band or wrap element 1 for at least partially, or fully surrounding fuel element 5. The fuel blocks 3 are solid wax, and have a through hole 17 from the top surface 18 to the bottom surface 19 to receive a taper 9, which is a scented wax jacket 22 around a wick 21. The wax in the puck 4 may be beeswax, vegetable wax, mineral wax, animal wax, soy wax, paraffin wax or other suitable wax. The wax in the fuel puck 4 is intended to have no scent, and it is intended to be slightly less expensive than a scented wax unit 9. This is one of the advantages of the technology, where the candle overall is less expensive for end users than using the entire candle block of scented wax. In any event, the scent of a fully scented candle can also become overpowering, so this embodiment of the technology balances the scent with long term fuel burning, light and ambience.
Where the fuel in the puck 4 is liquid fuel or oil, which is contemplated as a fuel for the assembly apparatus, the skin would form a complete skin and fully surround the fuel, but a puck 4 would still be formed. There would even be as part of the puck 4, the through hole 17, so as to form a donut or toroid, or cylindrical disc with a through hole 17 (in some embodiments such as those with a circular cross section), as discussed below.
It is the surface of the puck 4 which is embossed to form locating or fastening surface formations 11 integral with the puck body. The embossed locating or fastening surface formations 11 may be knurled, stamped or moulded formations extending above the surface or the skin. They are intended to be bosses 12, being small stacks 13 about 1 mm across and about 1 mm or 2 mm high and intended to be configured to crush or melt into one another to fuse or bond different adjacent pucks 4 together. There may be any kind of arrangement of stacks, including those across the top and bottom surfaces nearly to the edges, or they may be in a kind of mating arrangement, where half the top surface may be embossed, while the other half may be free, so as to facilitate fastening to an adjacent puck 4. The bosses 12 may be spaced to allow an inter-fit location between surfaces of adjacent pucks 4, where there is not really much crushing, but merely just an accommodation where one boss on one surface fits between two bosses on the corresponding surface of the other puck 4.
The skin or the wax may be provided with recesses and/or bosses 12, and they may be moulded on or pressed on into the skin or wax surface.
It can be seen that the bosses 12 can take the form of spaced-apart arcuate ribs (
The skin 14 may be a packaging layer 15 for a wax puck, or indeed the packaging layer may be a separate layer on the outside of the other skin. The packaging layer 15 is a cartridge for containing one or more of the fuel elements 5.
The packaging layer 15 includes a sleeve 16 which form a cartridge 16A for receiving the one or more fuel elements 5. In some embodiments the sleeve 16 may receive a plurality of pucks 4, but there will be embodiments available, it is contemplated, where there is just one long pillar disposed inside the sleeve, and a dispenser includes a cutter (not shown) to cut off a selected length of the fuel pillar. In the embodiment shown, it is to be understood that there will be a plurality of fuel elements 5 disposed in the cartridge sleeve 16, perhaps separated if necessary by a liner to inhibit welding together in the sleeve 16, but the dispenser, as will be explained below, will select one puck 4 at a time, and drop each one in the assembly zone 40 for assembly with a taper 9 and combining with the other pucks 4 by pressure.
In one embodiment the packaging layer includes a cardboard tube element for protecting the fuel element from damage and from adjacent fuel elements during transportation or during use or storage.
The skin 14 may be scented with a scent, but it is to be understood that the main scent unit is the taper 9. The taper 9 is intended to be sold in stacks, which may be cylindrical to fit in an (optionally) cylindrical through hole through the pucks 4. It is contemplated that the tapers 9 may be semi-cylindrical in section (to obtain a scent mix by placing two together in the through hole 17.
The skin may be about 0.1 mm thick or about 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 or 1.0 mm thick.
Many puck 4 shapes are contemplated to work, and each kind has different advantages: cylindrical pillars are easy to load, easy to handle, to hold in the hand, and make an attractive pillar candle.
But the puck 4 may be a square prism to facilitate ready formation of a square-sided pillar candle, which can be attractive. This is shown in
The fuel element 5 may be in the form of a square-section pillar (
For that matter, the through holes 17 in the fuel element 5 may be square, splined or star shaped (
Each fuel element is about 10 mm high and about 30 mm across.
Other useful dimensions of the fuel element 5 are contemplated for various reasons, and advantages, and they may be about 5 mm, 7 mm, 12 mm, 15 mm, 18 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 50 mm, 60 mm, 75 mm, 80 mm, 90 mm, 100 mm, 125 mm, or 150 mm high. For various reasons, the fuel elements may also be about 20 mm, 25 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 75 mm, 80 mm, 90 mm, or 100 mm across.
As shown in
The hole 17 for the taper 9 may be square in section as shown in
The taper 9 wax scent includes essential oil to provide the scent.
The taper 9 may be infused in the wax with a medicament such as antiviral, or antibacterial medicament.

So, the candle 25 produced by the assembly apparatus 10, 110, 210, is shown in
A medium candle and a large candle are shown in
If the fuel is liquid, it can be a good idea to include a closure on the container.
Alternatively, the candle 25 includes a single block fuel element 5 cut from a fuel block in a cartridge 16A. The process and the apparatus for cutting the fuel element 5 from the fuel block in a cartridge 16A is described below and shown in
The housing 60 is provided to protect and support the components described below, the housing 60 including a user interface 62 for actuating the candle building process. The housing 60 includes an access means 61 for loading fuel into the reservoir 20. The access means 61 may be a lid 61 or a port (not shown). The port may have an automatic lid which swings out of the way when the solid fuel block 5 or the cartridge 16 is inserted. The access means 61 is intended to provide access for solid fuel blocks. The lid 61 could be hinged or sliding.
The reservoir 20 is disposed in the housing 60 and is configured to receive and temporarily hold about ten, a dozen, fifteen, twenty, twenty five, thirty, thirty five, or up to about fifty fuel elements 5. The fuel elements 5 are in a stacked disposition inside a cartridge 16, which can be loaded straight into a tube 26 of the reservoir 20. The reservoir includes at least one hollow tube 26 of a cross sectional dimension and shape which cooperates with that of the one or more fuel element cartridges 16. One form of cartridge 16 contains a solid fuel pillar and the dispenser 30 dispenses fuel elements 5 by cutting one or more from the solid fuel pillar as described below.
In the apparatus shown in
In the apparatus shown in
The cartridge outer jacket 16A may act as a loader for the wax blocks. The wax block or pucks may be dispensed therefrom into the magazine. This makes cutting fuel elements or pucks 4 from the block of fuel 5, and dispensing, easier.
The fuel magazine fame 27 is configured to operatively mount into the reservoir 20 for ready loading. The fuel magazine frame 27 is shown to slide from above, swing from one side, or slide in from the side as shown in
The reservoir 20 includes an inlet 28 at a top end and an outlet 29 at a base end for fuel 5 flow into and out; the outlet leading to an inlet of the dispenser 30 for transferring one or more fuel elements 5 thereto.
The reservoir 20 includes a heating unit 29 which is in the form of a heating jacket and is shown in
The heating unit 29 may facilitate the use of wax flakes or granules, which can be melted or warmed to form a more dense fuel block.
The fuel used in the reservoir may be flakes or granules or solid blocks, since they can be pressed with the press 80. The press 80 and/or the heat can still facilitate a the convenience discussed herein, being a fairly rapid candle formation process.
The dispenser 30 includes an inlet closure 32 for selectively inhibiting access of fuel elements 5 from the reservoir 20. The dispenser 30 also includes an outlet 33 for transporting the fuel elements 5 from the reservoir 20 to the assembly zone 40.
The dispenser 30 includes a selector 34 for selecting a particular one or more fuel elements from selected portions of the tube 26 or magazine 27. The selector 34 is a rotating transporter 35 which includes one or more recesses 36, cooperating in cross section with the fuel elements 5 for receiving fuel elements 5 for loading into the assembly zone 40. The selector 34 in an embodiment not shown, is a drive for rotating the magazine 27 to align the reservoir outlet 29 with the dispenser inlet for transport to the assembly zone 40.
The dispenser 30, in one embodiment (
The loader 50 includes a loader 52 for loading the taper 9 into the fuel stack 8. The loader 52 includes a holder 53 for holding the taper 9 so it is kept in a stable position on the loader 52 while the loader is in motion. The holder may be a clamp or at least a pair of resilient jaws for holding the taper 9.
The loader 52 includes a drawer 54 which is disposed in a wall of the housing 60, which receives the taper 9 from the user, and transporting the taper 9 to the assembly zone 40. The loader 50 includes a drive 55 for driving the taper 9 into the fuel stack 8; or, the loader 50 includes a clamp and a release to drop the taper 9 into the stack 8.
The drive 55 includes a press 80 for pressing the taper 9 into the fuel stack 8. The press 80 includes a press plate 82 for pressing the stack together and for pressing the taper 9 into the stack.
The assembly zone 40 includes a loading zone 42 at an entrance thereof, for receiving a candle container 23. The loading zone 42 includes a door 43 for controlling access to the assembly zone 40. The loading zone 40 includes a drawer 44 to assist in transporting the container 23 to the assembly zone 40. The loading zone 42 includes an access controller 45 described below for inhibiting access to unauthorised containers.
Shown in
The landing body 94 is an extendable drawer 96, extendable from the housing 60, by swinging or sliding from the housing 60. A button 97 is configured to unlock and extend the drawer 96. In one form, the sampling module is disposed under a closure 32 for the housing 60.
As shown in
A wallet 76 of scent samples is shown in
The housing 60 includes a user interface 62 for actuating the candle building process. The user interface 62 includes an actuator 64 which causes the building process to commence. The actuator is a button 65 for simplicity of use.
Referring to
The processor 72 may be any suitable microprocessor, for example an ESP8266 with Wi-Fi capability, or an ESP32 with Wi-Fi and Bluetooth capability. In some embodiments a single processor may be used. In other embodiments one or more processors may be used to implement various functions of the machine 10 as described herein
The onboard processor 72 is configured to instruct the building of a candle upon receipt of data relating to the presence of an authorised container, or in response to a press of the actuator 64. Candles of a selected height may be assembled, under the control of the processor 72, depending on the length or number of presses of the button 65. In one embodiment, the onboard processor 72 is configured to implement the assembly of a candle of a low height (two fuel elements) if the button 65 is pressed once, and of a medium height (three fuel elements) if the button 65 is pressed two times, and of a tall height (four fuel elements) if the button 65 is pressed three times. The control system 70 includes a wireless module 75 for communicating with a mobile device for configuration and remote control.
Alternatively the processor 72 may instruct the cutting of a fuel block 5 from the fuel 6 in the reservoir 20 by actuating the cutter 90 and dispensing the fuel block 5 into the container in the assembly zone 40.
On the actuator button 65 there is disposed a biosensor which identifies the fingerprint of the user as authorised to operate the candle builder.
The access controller 45 its in communication with a reader 47 and an interlock module 48 in the processor so that only containers and fuel which are of a selected geometry or fitted with a security coating or strip or tag are allowed through into the loading/assembly zone 40.
The access controller 45 also inhibits operation of any part of the candle assembly apparatus 10 until a reader 47 reads an authorised message on a security coating or strip or tag, which may be disposed on the container or the wax fuel 5 or the taper 9. There is provided a magazine access controller 46 which includes similar interlock features as those of the loading zone access controller 45. The magazine access controller 46 includes a reader 47 to read a security coating or tag or strip on the fuel cartridge or fuel pillar. The access controller and/or magazine access controller includes an optical reader to read a barcode on the magazine, fuel cartridge or container. The barcode is stamped into the fuel. If the reader 47 reads the right code on the security strip then the access controller allows the candle assembly to begin. The reader 47 adjacent the taper loader drawer also provides access control. These access control readers are shown in
An alternative access controller is arranged such that there is a biosensor for detection of a selected gene or constituent part of the wax. Only authorised types of wax are contemplated to be able to be used in the candle builder 10, 110 and the authorised type of wax is identified by the biosensor. The biosensor is a gene sensor which identifies a selected wax or scent by the presence of a gene or other watermark. The biosensor is operatively connected to an interlock and the interlock will shut down the operation of the candle builder if the gene is not detected in the wax or cartridge or candle container in the assembly zone.
In some embodiments, the machine 10 includes one or more sensors 71 adapted to sense an identifier associated with a fuel element 5 and/or a fuel cartridge 16. The identifier may be associated with one or more identification particulars such as the type of fuel, the origin of the fuel, a vendor or manufacturer of the fuel, etc. The processor 72 is configured to receive the identifier data from the sensor 71, and to cause the network module 75 to communicate the identifier data to an external and/or remote computing system, for example a user device (such as a smart phone or laptop), a server, or a computer, etc.
The processor 72 may be any suitable microprocessor, for example an ESP8266 with Wi-Fi capability, or an ESP32 with Wi-Fi and Bluetooth capability. In such embodiments, the network module 75 would then include the onboard networking capability of the microprocessor.
In some embodiments the identifier may include an optical identifier such as a QR code; in these embodiments the sensor 71 includes an optical sensor such as a camera configured to input the QR code and provide the QR code data to the processor 72 for extracting the identifier data.
In some embodiments the identifier may include a radio frequency identifier (RFID) in the form of a passive or active RFID tag. The sensor 71 in such embodiments includes an RFID antenna adapted to query the RFID tag and to communicate the RFID tag identifier data to the processor 72.
It will be appreciated that various forms of identifiers can be used (tags, labels, etc.) that are adapted to be sensed by associated sensing mechanisms, for example optical codes such as barcodes, proximity cards using near-field communication (NFC), location tracking technologies such as GPS, nanotechnologies or nano-barcodes, etc.
In some embodiments the control system 70 functions as a reader, whereby the sensors 71 sense or detect an identifier, and the processor is configured to process the sensed data in order to read the data associated with the identifier. In other embodiments, the machine 70 may include a separate reader comprising a reading sensor and an associated reader processor.
In some embodiments the machine 10 includes a machine identifier. In these embodiments, the processor 72 may be configured to associate the element identifier and the machine identifier, and to cause the network module 75 to transmit the associated identifiers.
In some embodiments the sensor 71 is adapted to sense the presence of a fuel element 5 in the dispenser 30, and the sensor 71 communicates each instance of an element 5 to the processor 72, and the processor 72 is configured to count a number of elements 5 used with the machine 10. In some embodiments the sensor 71 is adapted to sense the presence of an element 5 or a cartridge 16 in the reservoir 20 and to communicate each instance of an element 5 or a cartridge 16 being received (or replaced) to the processor, and the processor 72 is configured to count the number of elements and/or cartridges used with the machine 10.
One embodiment of the assembly apparatus, shown in
Another embodiment, shown in
In operation the processor 72 wakes up when it receives data from a sensor 71, for example the camera 73 or container sensor 74, if a container is detected in the assembly zone 40 or when the processor 72 receives data from the user interface 62, eg from button 65 to wake up and start the assembly process. The sensor or camera checks whether the container is locked into the loading drawer by checking clearance between the container and the base of the drawer. The camera or sensor may assess the size of the container and send that data to the processor 72. If the container is assessed to be below a small threshold, then the processor 72 will instruct the dispenser 30 to cut or dispense a small size or number of fuel elements 5. If the container is assessed to be medium sized, then the processor 72 will cut or dispense a medium size or number of fuel elements 5. And so on for large size containers.
The processor 72 receives data from sensors in the loader 50 that the loader drawer 52 is open. The user inserts the taper 9 into the loader 50. The access control reader 47 adjacent the drawer 52 reads for the security strip on the taper 9 and if it is present, then the access control module allows the loader 50 to proceed with loading the taper into the fuel stack 8 described below.
The processor 72 then actuates the dispenser to cut, using the cutter 90, a fuel element 5 from the fuel 6, of the right size for the container. If the cartridge 16 has a plurality of fuel pucks 4 stacked therein, then the processor 72 causes the turntable to rotate to fill the container with the right number of wax pucks 4 to form a stack 8 of the right size for the container.
The wax puck dispenser 30 dispenses pucks in a stack in the container.
The processor 72 may actuate the heating probe 98 to warm the inside of the bore in the stack 8. There may also be provided a heating jacket around the cartridge 16 to warm the wax up to a temperature where the wax may slump or be formable under pressure. This is suitable for a container 23 which has angled or curved walls. This arrangement is shown in
The processor 72 then causes the press 80 to drive the taper from the loader into the bore of the stack 8.
The other embodiments of the apparatus are controlled by the processor 72 in a similar way. For example, in the kiosk 300, shown in
A user may pay with a credit card or phone tap zone 368 or by inserting coins and/or notes in a slot 369. The processor 72 then causes the loader 50 to insert a taper into the warm bath of wax, as shown in
The building cycle described above should take only a minute or two and then the user can then light the candle and then use the candle. This is a convenient way to build a tailored candle for a mood—select the desired taper scent then build up some fuel around it, and then burn it, without fuss or destroying the mood.
In
To form the candle 25 with the tool and the kit, the user cuts out a fuel block from a cartridge 16 of the size which is about right for the container 23. The user may also stack pucks 4 to form a fuel pillar. The pucks 4 may be already bored with through holes 17, or the user may form one or more through holes 17 in the fuel block 8. Then, the user places one or more tapers 9 into the one or more holes 17 in the fuel block 8. The tool 85 then is fitted over the taper 9, which is received in the recess 89. The user then drives the tool downwards and then the taper 9 is driven into the bore 17. The recess 89 is an interference fit on the taper 9, or there may be a gripper or a clamp (not shown) in the recess 89 to hold the upper part of the taper 9. Therefore the tool 85 may be rotated which may then cause the taper 9 shown in
The user may of course hand thread the taper 9 from
The user may, alternatively, load the container with the taper 9, and sprinkle granular fuel into the container 23. The tool 85 is then pressed down and the candle 25 is formed.
A kit as shown in
