Background Art The worship of ancestors has deep roots in Oriental societies. In particular, interest in funeral ceremonies is high. Recently, the general tendency of the funeral ceremony is to put the ashes of the deceased after cremation into a cinerary urn, rather than to hold the traditional burial service.

Generally, a method for manufacturing a cinerary urn follows a porcelain manufacturing process. Alternatively, a cinerary urn may be manufactured by way of a stone processing

process or a wood molding process.

However, such cinerary urns have respective advantages, but at the same time have several problems upon usage. The specific descriptions of these problems are as follows.

First, with reference to a porcelain cinerary urn, it has been widely used due to its easy manufacture and excellent surface color. However, there is a serious problem in that it has poor ventilation because air spaces in the porcelain cinerary urn are clogged due to several heating steps during its manufacturing process.

That is, the porcelain cinerary urn is not well ventilated, resulting in its inside collecting moisture and the ashes therein being oxidized. Furthermore, an offensive odor is generated from the oxidized ashes.

Another serious problem in the porcelain cinerary urn is that because the porcelain cinerary urn is manufactured by heating an earthen cinerary urn model, overall strength is weak and cracks or breakage are liable to occur. Therefore, it is unsuitable as a cinerary urn requiring long term storage.

With reference to a stone cinerary urn, due to direct processing of stone, manufacture is difficult and thus that expensive. Furthermore, it is liable to become discolored after being exposed in air for a long time.

Finally, with reference to a wood cinerary urn,

manufacture is easy but the hardness of its surface is weak and thus damage to its surface is liable to occur.

Disclosure of the Invention Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a loess cinerary urn and a loess cinerary urn manufactured by the method, in which the strength of the cinerary urn is increased, simultaneously with preventing humidification in the inside of the cinerary urn.

Another object of the present invention is to improve the hardness of the surface of the loess cinerary urn by reinforcing the surface using a plate inlaid with mother-of- pearl.

Another object of the present invention is to adhere a plate inlaid with mother-of-pearl to the surface of a biscuit fired loess cinerary urn for a long time.

Another object of the present invention is to maximize adhesive strength between an adhesion layer and a loess surface by applying a crushed rock-mixed curing agent on the loess surface and then pressing the crushed rock-mixed curing agent so as to insert the crushed rock into the loess surface with weak surface hardness and roughness, in a

process for forming an adhesion layer to which a plate inlaid with mother-of-pearl is adhered.

Another object of the present invention is to improve the strength of a loess wall using the tensile strength of fabrics by depositing the fabrics on the outer surface of a crushed rock-mixed curing agent.

Another object of the present invention is to improve the strength of a loess wall using the tensile strength of a Korean paper by depositing the Korean paper together with a curing agent on a loess surface, in a process for forming an adhesion layer to which a plate inlaid with mother-of-pearl is adhered.

Another object of the present invention is to prevent charcoal powder contained between the inner and outer walls of the cinerary urn from scattering by finishing the upper sides of the inner and outer bodies and the lower sides of the inner and outer covers of the cinerary urn with a Korean paper.

A further object of the present invention is to record the life history, the will or the writing to the memory of the deceased on the surface of a Korean paper which is deposited on the upper sides of the inner and outer bodies and the lower sides of the inner and outer covers of the cinerary urn.

In accordance with one aspect of the present

invention, the above and other objects can be accomplished by the provision of a method for manufacturing a loess cinerary urn, comprising the steps of biscuit firing cinerary urn models in loess to manufacture basic inner and outer loess cinerary urns each consisting of a body and a cover; depositing charcoal between the inner and outer loess cinerary urns while inserting and assembling the inner loess cinerary urn into the outer loess cinerary urn; forming an adhesion layer on the surface of the outer loess cinerary urn; and adhering a conventional plate inlaid with mother- of-pearl to the surface of the adhesion layer while bending the plate.

In accordance with another aspect of the present invention, there is provided a loess cinerary urn, comprising basic inner and outer loess cinerary urns which comprise a pair of the bodies and covers in a state wherein the inner loess cinerary urn is inserted into the outer loess cinerary urn, and a charcoal layer deposited therebetween; an adhesion layer which is formed on the surface of the outer loess cinerary urn so as to adhere a plate inlaid with mother-of-pearl thereto to thereby reinforce and smooth the surface of the loess wall; and a conventional plate inlaid with mother-of-pearl which is adhered to the surface of the adhesion layer.

Best Mode for Carrying Out the Invention Hereinafter, the present invention will be described with reference to the accompanying figures.

Fig. 1 is a cross sectional view of the loess cinerary urn of the present invention and Fig. 2 is an expanded view of A part in Fig. l. First, the construction of the loess cinerary urn of the present invention is as follows.

The loess cinerary urn comprises basic inner and outer loess cinerary urns 1,2 which comprise a pair of bodies 11, 21 and covers 12,22 that are biscuit fired at 600 to 850 C in a state wherein the inner loess cinerary urn is inserted into the outer loess cinerary urn, and a charcoal layer 3

deposited therebetween; an adhesion layer 4 which is formed on the surface of the outer loess cinerary urn 2 so as to adhere a plate inlaid with mother-of-pearl thereto to thereby reinforce and smooth the surface of the loess wall; and a conventional plate inlaid with mother-of-pearl 5 which is adhered to the surface of the adhesion layer 4 while bending the plate using heat.

In particular, Korean papers 13,23 are deposited on the upper sides of the inner and outer bodies 11,21 and the lower sides of the inner and outer covers 12,22 of the basic inner and outer loess cinerary urns 1,2 so as to prevent charcoal powder from scattering.

As shown in Fig. 3, the adhesion layer 4 comprises a curing layer 41, a lacquered layer 42 and an adhesive agent layer 43. The curing layer 41 comprises a curing agent having or being mixed with a reinforcing means so as to reinforce (prevention of cracks) the surface of the outer loess cinerary urn 2, and its surface is smoothly polished.

The lacquered layer 42 is formed by lacquering the curing layer once or more, drying the lacquered surface, and smoothly polishing the surface so as to display the peculiar color of mother-of-pearl on the polished surface of the curing layer. The adhesion agent layer 43 is formed on the surface of the lacquered layer so as to adhere a plate inlaid with mother-of-pearl 5 thereto.

Fig. 3a illustrates a step for forming a curing layer in the adhesion layer forming process in accordance with the present invention. Crushed rock 411 is used as a means for reinforcing the curing layer 41. If the crushed rock 411 is mixed with a curing agent and is deposited on the surface of the outer loess cinerary urn, it is stuck in the surface of the outer loess cinerary urn with weak surface hardness and then fills depressions on the surface. Therefore, adhesive strength between the curing layer 41 and the loess surface can be maximized.

Fig. 7 is a cross sectional view of a lacquered loess cinerary urn in accordance with the present invention. A lacquered layer 6 is formed on the outer surface of a plate inlaid with mother-of-pearl through lacquering once or more.

As a result, the plate inlaid with mother-of-pearl is finally surface treated.

Fig. 8 is a cross sectional view of a loess cinerary urn in which a curing layer is formed during an adhesion layer forming process in accordance with another embodiment of the present invention. Fabrics 44 are deposited on the curing layer 2 comprising a curing agent and crushed rock 411. Therefore, the tensile strength of a loess wall is reinforced with the fabrics 44 to thereby increase the strength of the loess wall even more.

Fig. 9 is a cross sectional view of a loess cinerary

urn in which a curing layer is formed during an adhesion layer forming process in accordance with still another embodiment of the present invention. A Korean paper 412 is used as a means for reinforcing the curing layer 41.

Therefore, the strength of the loess wall is improved through the tensile strength of the Korean paper 412.

Furthermore, the Korean paper makes the rough surface of the loess wall smooth and thus prevents the surface of the lacquered layer 42 from warping. Therefore, the plate inlaid with mother-of-pearl 5 can be firmly adhered.

Hereinafter, the method for manufacturing the loess cinerary urn with the construction as mentioned above will be described.

As shown in Figs. 1 to 5, first, basic inner and outer loess cinerary urns 1,2 comprising bodies 11,21 and covers 12,22 are prepared by biscuit firing cinerary urn models in loess (10; see Fig. 1). That is, air spaces are maintained in the loess cinerary urns because the cinerary urn models in loess are biscuit fired. Therefore, it is possible for the walls of the inner and outer loess cinerary urns 1,2 to be porous.

Next, the inner loess cinerary urn 1 is inserted and assembled into the outer loess cinerary urn 2. Then, charcoal is deposited between the inner and the outer loess

cinerary urns 1, 2 for the purpose of dehumidification, insect proofing and sterilization (20; see Fig. 1).

Next, an adhesion layer 4 is formed on the surface of the outer loess cinerary urn 2 (30; see Fig. 3).

Next, a conventional plate inlaid with mother-of-pearl 5 is bent and adhered to the surface of the adhesion layer 4 (40; see Fig. 4) to thereby manufacture a final loess cinerary urn.

In particular, in the plate inlaid with mother-of- pearl adhering step 40, breakage of the plate inlaid with mother-of-pearl 5 is prevented because the plate inlaid with mother-of-pearl 5 is bent by mild heat.

As shown in Fig. 1, between the charcoal depositing step 20 and the adhesion layer forming step 30, the upper sides of the inner and outer bodies 11,21 and the lower sides of the inner and the outer covers 12,22 of the inner and the outer loess cinerary urns 1,2 are finished with Korean papers 13,23 (50 in Fig. 5).

Accordingly, the Korean papers 13,23 make it possible not only to prevent charcoal powder of the charcoal layer 3 from scattering but also to record the life history or the will of the deceased.

As shown in Fig. 7, after adhering the plate inlaid with mother-of-pearl 5 to the adhesion layer and then drying it for a predetermined time, an adhesive agent protruded

outside the surface of the plate inlaid with mother-of-pearl is removed and lacquering is carried out once or more.

Therefore, damage to the surface of the plate inlaid with mother-of-pearl is prevented and peculiar color of the mother-of-pearl is displayed. Finally, a brightener may be further applied on the surface of the lacquered layer 6 for the surface brightening.

Now, the process for forming the adhesion layer will be described hereinafter.

With reference to the adhesion layer forming process 30 as shown in Figs. 3a to 3c, first, a curing layer forming step (301; see Fig. 3a) is carried out. In detail, a curing agent together with a reinforcing means is deposited on the surface of the outer loess cinerary urn 2 and cured to form a curing layer 41. Then, the surface of the formed curing layer is smoothly polished.

Next, a lacquered layer forming step (302; see Fig.

3b) is carried out. In detail, lacquering is carried out on the polished curing layer 41 once or more to form a lacquered layer 42 and the surface of the lacquered layer 42 is smoothly polished. Therefore, the peculiar color of the plate inlaid with mother-of-pearl to be adhered in the subsequent process is displayed and adhesion strength of an adhesive agent is improved.

Next, an adhesive agent applying step (303; see Fig.

3c) of applying an adhesive agent such as glue on the polished lacquered layer 42 is carried out.

In particular, in case of using crushed rock 411 as a reinforcing means during the curing layer forming step 301, if the crushed rock 411 is mixed with a curing agent and is deposited on the surface of the outer loess cinerary urn, it is stuck in the surface of the loess cinerary urn with weak surface hardness and then fills depressions on the surface.

Therefore, adhesive strength between the curing layer 41 and the loess cinerary urn can be maximized.

Fig. 8 is a cross sectional view of a loess cinerary urn in which a curing layer is formed during an adhesion layer forming process in accordance with another embodiment of the present invention. Fabrics 44 are deposited on the curing layer 41 comprising a curing agent and crushed rock 411. Therefore, the tensile strength of a loess wall is reinforced with the fabrics 44 to thereby increase the strength of the loess wall even more.

Fig. 9 is a cross sectional view of a loess cinerary urn in which a curing layer is formed during an adhesion layer forming process in accordance with still another embodiment of the present invention. A Korean paper 412 is used as a reinforcing means of the curing layer during the curing layer forming step 301. Therefore, the strength of

the loess wall is improved through the tensile strength of the Korean paper 412. Furthermore, the Korean paper makes the rough surface of the loess wall smooth and thus prevents the surface of the lacquered layer 42 from warping.

Therefore, the plate inlaid with mother-of-pearl 5 can be firmly adhered.

Industrial Applicability As apparent from the above description, the present invention provides a loess cinerary urn, in which oxidation of ashes and generation of offensive odor are prevented by removal of moisture in the cinerary urn, and at the same time, strength of the cinerary urn is reinforced.

The hardness of the surface of the loess cinerary urn is improved by reinforcing the surface using a plate inlaid with mother-of-pearl. Therefore, damage to the surface of the loess cinerary urn is minimized.

The adhesion of a plate inlaid with mother-of-pearl to the surface of a biscuit fired loess cinerary urn is maintained for a long time. Therefore, the cinerary urn can be preserved for a long time.

The adhesion of a plate inlaid with mother-of-pearl to the surface of a loess cinerary urn is maintained for a long time by maximizing adhesive strength between an adhesion

layer and a loess surface through a crushed rock-mixed curing agent, in a process for forming an adhesion layer to which the plate inlaid with mother-of-pearl is adhered.

The strength of a loess wall using the tensile strength of fabrics is improved by depositing the fabrics on the outer surface of a curing layer. Therefore, a loess cinerary urn with sufficient strength may be provided.

The strength of a loess wall using the tensile strength of a Korean paper is improved by depositing the Korean paper together with a curing agent on the surface of a loess cinerary urn. Therefore, a loess cinerary urn with sufficient strength may be provided.

Charcoal powder contained between the inner and outer walls of the cinerary urn is prevented from scattering or escaping by finishing the lower sides of the inner and outer covers and the upper sides of the inner and outer bodies of the cinerary urn with the Korean paper. Therefore, the effectiveness of a charcoal layer may be maximized.

Finally, the life history, the will or the writing to the memory of the deceased may be recorded on the surfaces of Korean papers which are deposited on the lower sides of the inner and outer covers and the upper sides of the inner and outer bodies of the cinerary urn. Therefore, descendants can appropriately honor the cinerary urns of their ancestors.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
