Wick holder and wick assembly for candle assembly
First Claim
1. A wick assembly comprising:
- an enclosed wick casing having a first open end and a second open end;
a wick extending between the first open end and the second open end with a portion of the wick surrounded by the wick casing; and
a restricted portion of the wick casing having a cross sectional area less than a cross sectional area of either the first open end or the second open end, wherein the restricted portion of the wick casing reduces an effective capillary flow capacity along the wick.

Abstract
A candle assembly includes a support base, a melting plate having a capillary pedestal, a wick holder that fits onto the capillary pedestal, and a fuel element that fits over the wick holder. The wick holder includes a sleeve having first and second open ends. A wick fits into the sleeve and extends between the open ends. The sleeve has a constricted portion, which is disposed between the open ends and has a cross-sectional area less than any other cross-sectional area between the open ends. The constricted portion reduces an effective capillary fluid flow capacity of the wick between the open ends, which may thereby regulate how quickly fuel is consumed when the candle assembly is burning. A capillary well disposed between the wick holder and the capillary pedestal may be adapted to promote a successful relight after an initial burn of the candle assembly. A candle holder, such as including the melting plate supported by a base, may be adapted to promote laminar air flow thereacross during a burn in a substantially calm atmospheric environment.

15. A wick holder comprising:
-
an elongate enclosed wick casing extending from a base portion and having a first open end and a second open end; and
a constricted portion of the wick casing, wherein the constricted portion restricts an effective capillary fluid flow capacity between opposite open ends of the wick casing. - View Dependent Claims (16, 17, 18, 19)

20. A wick assembly comprising:
-
a tube having a sidewall extending between a first open end and a second open end;
a base at one end of the tube for supporting the tube in a substantially vertical position;
a wick at least partly disposed in the tube and extending between the first open end and the second open end; and
means in the sidewall for restricting a capillary fluid flow capacity of the wick between the first open end and the second open end.
