FR2634423A1 - Process for producing thick-walled decorative enclosures of the multicoloured or one-coloured rock type, laminated or otherwise, for candles - Google Patents

Abstract

The process consists in producing a decorative wall of adjustable thickness and relief by pouring a liquid binder into a cavity formed by a filter element, around which generally coloured granulates have been distributed according to the desired effect. The physical and chemical conditions of the diffusion of the liquid are defined in order to ensure the setting solid of the granulates and so that at the end of the operation the lower part of the filter is once again empty in order to make it possible to cast a candle therein or for other purposes.

Description

PROCESS FOR PRODUCING DECORATIVE ENVELOPES
WITH THICK WALLS OF THE MULTICOLORED OR UNICOLORED ROCK TYPE
LAMINATES OR NOT FOR CANDLES
The present invention relates to so-called candles
shortbread which it expands and improves the possibilities of
realization to obtain external walls of candle
of varied volume, shape and color, this process can
serve & make decorative containers other than
candles.

In the classic process we use a sand
humid, which allows to form an interior cavity
stable at the time od we pour the wax which will coat the
sand on a thin layer and at the same time the excess
uncoated sand is separated from the candle by the
brushing.

The water in the sand cools down very
wax quickly and limits its diffusion within
sand allowing only weak walls to be obtained
thickness (a few millimeters).

The method of the present invention allows
separate the candle making into two phases
container creation
then pouring the candle itself.

It is possible by this method to use
sands or other colored aggregates and powders, of a kind
varied - dry or locally impregnated - inert or
crystallizing with the binder (case of powders-containing
plaster or cement) - cold or preheated, so
to direct and regulate the diffusion within these
aggregates of a liquid, generally organic like wax
& preferably higher melting point & that of the
inner candle, but this liquid can also be a
aqueous solution if the aggregates have been chosen to
solidify & its contact. Whatever its nature is
liquid has the function of ensuring the solidification of
different layers of aggregates & the place reached by
dissolving it, possibly adding coloring
local and reflections caused on the outer wall of the
container thus produced.

The principle of the invention consists, using a
porous surface filter or screen, metallic fabrics,
preferably non-flammable for the production of candles, to constitute one or more closed volumes at least on the vertical faces (cylindrical in general). This fairly rigid sieve will prevent the aggregates from filling the interior volume reserved for the fuel part of the candle, but on the other hand will allow the liquid to diffuse outside the aggregates within the liquid to serve as a binder.

 The volume of binder and its temperature are determined to be almost completely absorbed.

 After the phase of solidification of the external wall of the spark plug, this filter can either be left in place, or be removed when it was designed to be dismantled or destroyed.

Example of realization:
In a container of appropriate size for the expected result (pressure cooker for example), a layer of materials is spread out for the bottom (at least 5mm). The filter is then placed on this aggregate bed, roughly centered in the container (for example a metal sieve formed in a cylinder open at both ends or just one and of equal height & the candle & make). The filter can have a shape other than cylindrical. Between the outer wall of the filter and the inner wall of the container Then, depending on the desired result, the
different layers of aggregates or powders and included them
sions that will appear on the wall of the candle or there
will give relief.

When you have reached the top level of the filter, you can
adjust the temperature of the assembly in order to prepare the
diffusion capacity of the binder.

. The volume of the binder is measured and its temperature adjusted
depending on the thickness of the wall you want
create.

Then the liquid binder is poured into the cavity so
& fill it completely and & maintain full
cavity until the measured volume is exhausted.

The upper layers of aggregates are thus impregnated
but then the diffusion of the liquid in the aggregates
almost completely empties the central cavity.

After a set time, you can either sink the
candle in the cavity according to the usual techniques
or beforehand the solidified wall is separated from
the excess of aggregates and we finish the surface condition
outside of the container to bring out the
shades and reliefs.

The outer part of the candle, when it has been
fully consumed, can be reused either for
put plants or flowers, either to sink a
new candle.
