Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a container candle that uses wax contained in the container as fuel.

[Prior art]

This type of container candle is disclosed in Japanese Patent Publication No. 56-13758, Japanese Utility Model Publication No. 55-55233, and Japanese Utility Model Publication No. 58, filed by the present applicant.
As shown in publications such as No.-7923 and No. 58-48331, there is a support tube that is installed upright in a container containing wax and into which melted wax can enter, and a support tube that is inserted into the support tube. It has a core tube from which a core material in the form of a fiber bundle protrudes from an opening at its upper end, and the wax is gasified and combusted at the head of the core material.

In each of the above-mentioned container candles, the combustion flame is maintained in a normal state with a constant size and does not change much. Therefore, container candles whose combustion flame is varied and have increased commercial value are used. was proposed in Utility Model Publication No. 57-4116. This container candle can arbitrarily change the combustion flame between a normal state with a fixed size and a flickering state where the size changes continuously, and this product is unique because it has such a unique function. High value.

[The problem that the idea attempts to solve]

The present invention provides a container candle in which the combustion flame has a more unique shape than the container candle, in particular, the combustion flame is separated from the head of the wick and suspended above it, thereby increasing the commercial value of the container candle. The aim is to increase

[Means to solve the problem]

The present invention provides the above-mentioned container candle, in which the outer periphery of the support tube is concentrically surrounded by a cylinder whose upper peripheral wall is provided with a plurality of elongated holes extending in the vertical direction.
The elongated hole forming portion of the cylinder is located on the outer periphery of the head of the core material.

[Functions and effects of the idea]

As a result, in the container candle of the present invention, combustion depends on the length of the cylinder surrounding the head of the core material upward from the head, the number of elongated holes, the width, the length, etc. The separation distance of the flame from the core head and the shape of the flame are determined, and a combustion flame of a desired shape floating at a desired position is formed. The reason why such a unique combustion flame is formed is not clear, but it is presumed to be due to the following reasons.

In other words, when the head of the core material in the container candle is ignited, the air around its outer periphery and above is heated, creating a local updraft, and the surrounding air is sucked into the inner hole through each elongated hole of the cylinder. be done.
However, the flow velocity of the incoming air near the head of the core material is not very fast, and the combustion flame in that part is not blown up, but the heat is transferred to the wax through the core tube and support tube, melting the wax and causing it to become combustible. Decomposes into gas and continues combustion. It is also believed that a part of the combustible gas mixes with the incoming air and is blown up in a heated state, forming floating combustion flames.
Further, the shape and formation position of this combustion flame are thought to be related to the outflow velocity, outflow amount, etc. of the airflow, and these are determined by the length of the cylinder, the number and shape of the elongated holes.

Therefore, the combustion flame is located in a floating state above and away from the head of the wick, which is a unique condition different from the combustion flame of conventional container candles.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 shows a container candle according to an embodiment of the present invention.

The container candle is a container 11 containing wax W.
The support tube 12 shown in FIG.
3 which is removably inserted into the support tube 12, a fiber bundle-like core material 14 shown in FIG. 4 which is inserted into the core tube 13, and a pair of upper and lower cylindrical bodies 15, 16 shown in FIG. 5 which form the main part of the present invention.

In each of these constituent members, the support tube 12, the core tube 13, and the core material 14 are the same as those shown in Utility Model Publication No. 57-4116, and the core tube 13 has a heat absorbing portion 13a provided at its upper end. It partially surrounds the outer periphery of the upper exposed portion of the core member 14 and is latched to the inner periphery of the upper end opening of the support tube 12 . Moreover, if the head of the core material 14 in this state is ignited, the core material 14
The wax that has been impregnated in advance melts, gasifies, and burns, and a portion of the combustion heat is transferred to the heat absorption section 1 of the core tube 13.
3a to the main body 13b of the core tube 13, and melts the wax inside and outside the core tube 13. Therefore, the molten wax enters the core material 14 and reaches the head of the core material 14 by capillary action, continuing combustion.

As shown in FIGS. 1 and 5, the upper cylindrical body 15 is formed to have the same inner diameter as the outer diameter of the lower cylindrical body 16, and a portion of its circumferential wall is cut off in the longitudinal direction to form a cross section C. It is ring-shaped and can expand radially outward. Therefore, the upper cylinder 1
5 is elastically fitted to the outer periphery of the upper end of the lower cylindrical body 16, and can be slid in the vertical direction to adjust its position. Further, this upper cylinder 15 has a plurality of long holes 15a, 15a, . . . extending in the longitudinal direction in its peripheral wall.
, and surrounds the entire outer periphery of the head of the core material 14.

In the container candle constructed in this way,
When the head of the core material 14 is ignited, the wax gasified at the head of the core material 14 is combusted in the same way as in conventional container candles, but the combustion flame F is emitted from the head of the core material 14 as shown in FIG. It is formed above and away from the area and appears in a floating state. In addition, in the container candle, when the upper cylinder 15 is slid in the vertical direction to change the opening area of each elongated hole 15a, 15ba..., the distance of the combustion flame F from the head of the core material 14 is increased accordingly. The distance L and the shape of the combustion flame F change. In this way, the combustion flame F of the container candle is extremely unique compared to the combustion flame of conventional container candles.
It has high commercial value.

The container candle has a unique combustion flame F.
It is presumed that the reason for forming is as follows. That is, in the container candle, when the head of the core material 14 is ignited, the air around the outer periphery and above it is heated to generate a local upward air current, and the air around the outer periphery of the upper cylinder 15 flows through the elongated holes 15a, 15a, . . .
... into the inner hole and its upper end opening 15b.
flows out from Therefore, a part of the combustible gas of the wax gasified at the head of the core material 14 is blown upward by the airflow flowing out from the upper end opening 15b of the upper cylinder 15, and is separated from the head of the core material 14. It is thought that the flame ignites in the upper part and forms a floating combustion flame F. Therefore, the core material 1 of such a combustion flame F
4 The shape such as the distance L from the head and the size is determined by the flow rate and flow rate of the airflow flowing out from the upper end opening 15b of the upper cylinder 15, that is, the opening area of each elongated hole 15a, 15a... of the upper cylinder 15. seems to be greatly influenced by For this reason, the upper cylinder 15
When you adjust the position by sliding it up and down, each slot 1
The opening area of 5a, 15a... changes, and as a result, the combustion flame F of a desired shape floats at a desired position.
is formed.

In this embodiment, a core tube 13 having a substantially Y-shaped heat absorption part 13a is employed, and an upper cylinder 15 is fitted to the upper end of the lower cylinder 16 so that its position can be adjusted in the vertical direction. Although an example of a container candle that employs a core tube is shown, in the present invention, a core tube that does not have a heat absorbing part can be used, and the upper cylinder body 15 is fitted into the upper end of the lower cylinder body 16. It is also possible to adopt the Further, the long hole 15a of the upper cylinder 15 may be formed by providing small diameter circular holes in series in the longitudinal direction.

FIG. 7 shows the cylindrical bodies 15, 1 in the above embodiment.
A first variant of No. 6 is shown. The cylindrical body 21 of this first modification is the same as the pair of cylindrical bodies 15 and 16 of the above embodiment.
The upper circumferential wall of the cylindrical body 21 is provided with a plurality of elongated holes 21a, and a notch 21c of a predetermined width extending from the upper end opening 21b between the two elongated holes 21a. This notch 21
c is formed to have approximately the same width as the heat absorption part 13a of the core tube 13 shown in FIG. By doing so, the cutout portion 21c can be closed and opened by the heat absorbing portion 13a as shown in FIGS. 8a and 8b.

Therefore, the heat absorbing portion 13a of the core tube 13 is
When the notch 21c is open in the position shown in FIG.
The airflow flows not only from the notch 21c but also from the upper end opening 21b of the cylindrical body 21, and the outflow speed of the airflow from the upper end opening 21b is low. Therefore, the combustion flame becomes a normal flame without being blown up. On the other hand, when the heat absorbing part 13a is in the position shown in FIG. 8b, the notch 2
When the cylinder 1c is closed, the air around the outer circumference of the cylinder body 21 flows in only through each elongated hole 21a and acts in the same manner as in the above embodiment, forming a floating combustion flame.

FIG. 9 shows the upper cylinder 15 in the above embodiment.
A second variant is shown. The upper cylindrical body 22 of this second modification is the same as the upper cylindrical body 15 of the above embodiment.
A notch 22c similar to the notch 21c of the cylindrical body 21 of the modified example is provided, whereby the upper cylindrical body 15
and the cylindrical body 21.
