(7) A cap 12 is positioned within a chamber 111 defined in the fuel reservoir 11. The cap 12 forms a recess. The cap 12 has at least one fuel injection hole 121 and a first positioning hole 122 both extending therethrough and in communication with the chamber 111 and the recess. In the embodiment, there are two fuel injection holes 121. Each fuel injection hole 121 is crescent-shaped.

(8) A thermal insulating member 13 is positioned within the recess of the cap 12. The thermal insulating member 13 has a second positioning hole 131 extending therethrough.

(9) A seal 14 is positioned between an outer periphery of the cap 12 and an inner periphery of the reservoir 11. The seal 14 is also retained by a rim 123 of the cap 12. The seal 14 seals a gap between the fuel reservoir 11 and the cap 12. The seal 14 is made of rubber. The seal 14 is ring-shaped.

(10) A cover 15 partially covers the recess of the cap 12 and is connected to the cap 12. The cover 15 has a width smaller than a width of the recess of the cap 12. The cover 15 is positioned above the thermal insulating member 13. The cover 15 has a third positioning hole 153 extending therethrough and the first and second clamping surfaces 311 and 312 are inserted through the third positioning hole 153. The cover 15 has a top side 151 and a bottom side 152 opposite the top side 151. The third positioning hole 153 extends through the top and bottom sides 151 and 152. The third positioning hole 153 has two end sections 1531 and a middle section 1532 positioned between and connected to the two end sections 1531.

(11) A wick 20 is inserted through the first and second positioning holes 122 and 131. The wick 20 has a top end 21 positioned above the cap 12 and a bottom end 22 positioned below the cap 12. The wick 20 is also inserted through the middle section 1532 of the cover. The top end 21 of the wick 20 is positioned above the cover 15. The cover 15 has at least two retainers 154 protruding therefrom and positioned on opposite sides of the third positioning hole 153. The wick 20 is made of metal and does not burn out. The top end 21 of the wick 20 has a substantially circular outer periphery. The bottom end 22 of the wick 20 has an outer periphery including two substantially parallel sides.

(12) A fixture assembly 30 holds the wick 20. The fixture assembly 30 includes a clamping member 31 with first and second clamping surfaces 311 and 312. The wick 20 is clamped between the first and second clamping surfaces 311 and 312. The first and second clamping surfaces 311 and 312 are inserted through the first and second positioning holes 122 and 131. The first and second clamping surfaces 311 and 312 are positioned between the at least two retainers 154, with one retainer 154 abutting an outer side of the first clamping surface 311, and with another retainer 154 abutting an outer side of the second clamping surface 312. The at least two retainers 154 are positioned on opposite sides of one of the two end sections 1531.

(13) The clamping member 31 includes two restrainers 32 abutting the first and second clamping surfaces 311 and 312 and the wick 20 is positioned between and restrained by the two restrainers 32. The restrainer 32 is fixed between the first and second clamping surfaces 311 and 312 in that the restrainer 32 has cavities correspond to protuberances of the first and second clamping surfaces 311 and 312.

(14) The first clamping surface 311 has at least one first notch 313 formed in an edge thereof. The second clamping surface 312 has at least one second notch 313 formed in an edge thereof and adjacent the at least one first notch 313. One of the restrainers 32 has a first side partially exposed through the at least one first notch 313 and a second side opposite the first side partially exposed through the at least one second notch 313. The at least one first and second notches 313 can facilitate insertion and positioning of the restrainer 32. In the embodiment, there are two first notches 313 and two second notches 313. Thus, one restrainer 32 corresponds to one first notch 313 and one second notch 313 and another restrainer 32 corresponds to another first notch 313 and another second notch 313, respectively.

(15) The clamping member 31 has a first support member 314 contiguous to the first clamping surface 311 and a second support member 314 contiguous to the second clamping surface 312. The thermal insulating member 13 has a surface bearing the first and second support members 314. The first and second support members 314 extend in opposite directions. The thermal insulating member 13 has a top surface 132 bearing the first and second support members 314 and a bottom surface 133 opposite the top surface 132.

(16) A hollow base 33 is positioned within the chamber 111. The base 33 is connected to the cap 12. The base 33 is positioned below the cap 12. The base 33 has a platform and a fourth positioning hole 332 extending through the platform. The wick 20 is inserted through the fourth positioning hole 332 and the bottom end 22 of the wick 20 is positioned within a hollow compartment 331 defined in the base 33. The first and second clamping surfaces 311 and 312 are inserted through the fourth positioning hole 332. Further, the base 33 has a side extending circumferentially and at least one orifice 333 extending through the side. Thus, the compartment 331 is in fluid communication with the chamber 111.

(17) The cover 15, the thermal insulating member 13, the cap 12, and the base 33 are connected together by at least one fastener 50, as shown in FIG. 4. The cover 15, the insulating member 13, the cap 12 and the base 33 have fastener holes in which the at least one fastener 50 engages.

(18) In addition, FIG. 5 illustrates filling the fuel reservoir 11 with liquid fuel 40. The fuel reservoir 11 is filled by pouring the liquid fuel 40 onto the cap 12 through an open end of the fuel reservoir 11 and a gap between the cap 12 and the cover 15. Then, the liquid fuel 40 will flow though the two fuel injection holes 121 into the chamber 111.

(19) In view of the forgoing, a user can see how much liquid fuel 40 is poured into the recess of the cap 12 and how much is left in the fuel reservoir 11. Furthermore, the fire display device 10 has a simple design and it is easy to manufacture and assemble its components together. Moreover, the chamber 111 of the fuel reservoir 11 receives the cap 12, the thermal insulating member 13, the wick 20, and the fixture assembly 30 to provide an enhanced aesthetic effect.

(20) The foregoing is merely illustrative of the principles of this invention, and various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention.
