Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the improvement of candles, particularly candles for keeping warm in a house.

[Prior art]

BACKGROUND ART Conventionally, it has been known that candles for house heat insulation improve combustion efficiency by wrapping aluminum foil around the outer periphery of the wax body. However, in conventional candles using aluminum foil, the wax body near the core is melted and consumed, especially when the temperature is low, but the outer periphery of the wax body, which is in contact with the aluminum foil, is exposed to external damage. Due to the cold air, sufficient melting was not achieved, leaving a peripheral area that surrounded the core and caused the flame to go out midway through.

[Purpose of invention]

The present invention aims to eliminate the above-mentioned drawbacks and provide a candle whose flame does not go out midway even when the temperature is low, preferably a candle for keeping a house warm.

[Structure of the idea]

In order to achieve the above object, the present invention has the following configuration. That is, the candle is characterized by a wax body with a built-in core and a metal-deposited plastic film wrapped around the outer periphery of the wax body.

Here, the metal-deposited plastic film may be any well-known plastic film provided with a metal-deposited layer. The vapor deposited layer is formed of a metal or (and) a metal compound by a well-known method such as vacuum vapor deposition, sputtering, or ionized electrostatic plating.

Examples of metals and metal compounds include Al, Zn, Cr,
Mg, Si, Ti, In, Mn, Ni, Pd, Sn, Fe, Se
It may be a simple substance, an alloy, an oxide, a nitride, a sulfide, a chalcogenide, etc., and is not limited thereto. Particularly preferably used is aluminum. The thickness of the vapor deposited layer is not particularly limited, but is usually 5 mμ to 500 m.
μ, preferably in the range of 10 mμ to 300 mμ.

The plastic film is a film made of well-known plastic, and is not particularly limited, but preferably a stretched film made of polyester, polypropylene, or the like. The thickness of the film is not particularly limited, but is preferably 30μ to 500μ.

A wax body with a built-in core is a well-known candle.

The metal-deposited plastic film wrapped around the outer periphery of the wax body, preferably wrapped integrally with the outer periphery of the wax body, may be deposited on both sides or on one side. The most preferable is single-sided deposition, with the deposition surface on the inside.
That is, it is wrapped so as to be in contact with the wax body.

When vapor deposited layers are provided on both sides of the plastic film, the flame becomes difficult to extinguish due to the heat insulating effect of the intermediate plastic film.

In addition, when the vapor deposition layer is provided on the inside on one side, the vapor deposition layer becomes a heating source for the wax due to the heat from the flame, and the outer plastic film acts as a heat insulator, so the flame is extinguished more easily than when the vapor deposition layer is placed on both sides. It becomes difficult.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a partial cross-sectional view of a conventional candle.
2 is a core body, 2 is a wax body, 3 is an aluminum foil, and 4 is a molten wax. Note that FIG. 1 shows a state in which the wax body remains unmelted at the outer periphery.

Figure 2 is a partial cross-sectional view of the candle of the present invention.
6 is an aluminum vapor deposited layer, and 6 is a plastic film. However, 1, 2, and 4 are the same as in Figure 1. As shown in the figure, the candle of the present invention has a wax body 2 wrapped around an aluminum vapor-deposited plastic film consisting of an aluminum vapor-deposited layer 5 and a plastic film 6. Although FIG. 2 shows a case in which the aluminum vapor deposited layer 5 is closely attached to the wax body 2 and is integrated, there is a case in which a gap is provided between the aluminum vapor deposit layer 5 and the wax body 2 and the aluminum vapor deposition layer 5 is not integrated. It may be. Also, wrapped in film means that the wax is wrapped in a film to prevent the molten wax from flowing out to the side of the metal-deposited plastic film that is not in contact with the wax while the candle is in use (lighting). It refers to everything that surrounds the body (however, the bottom of the candle may be open).

[Effects and uses of the idea]

By configuring the present invention as described above,
Reflection of light heat and prevention of temperature drop around the outer periphery of the wax body increases the amount of molten wax, significantly improving combustion efficiency, and prevents the flame from extinguishing midway as no insoluble wax remains on the outer periphery. It shows an extremely excellent heat retention effect for cold-proof greenhouses.

In addition, those using metallized films can block light from the outside, and do not interfere with the normal growth of garden crops that require brightness during the day and darkness at night, such as those that require differentiation between day and night. It is extremely effective in keeping you warm.

The candle of the present invention is preferably used for keeping greenhouses warm, especially garden greenhouses.
