Description

Field of technology

The present invention relates to a burial urn and a method for its production, which will find application in the social sphere and in particular for the transformation of the burial process by cremation into an environmentally friendly and environmentally friendly action.

BACKGROUND OF THE INVENTION

Cremation is now used as an alternative to classical burial, as it requires less space and creates fewer environmental problems. Cremation urns can be ceramic, glass, metal, wood, stone and others and in various shapes. Degradable urns made of paper, sand and other processed biomaterials are also known.

Patent document US 2017157853 A1 discloses a burial urn and a method for its production, which method comprises the following operations: preparation of a starting material comprising perishable powder and composite powder, in which the two types of powder are mixed in a ratio of 1: 4 and to a binder is added to them. The resulting mixture is fed to an inlet container on a 3D printer for printing the urn without subsequent firing. The composite material is selected from materials comprising at least one of clay, wood particles, plastic particles, silica or sand, stone particles, metal dust and the like. The binder is of chemical origin and is selected from resin, collagen, casein, cement or wax adhesive.

In most cases, it is unacceptable for the relatives of the deceased to use an urn made by mixing the mortal can with composite material.

Technical essence of the invention

The object of the invention is to provide a burial urn and a method for its production, which urn is made of degradable materials in the soil, is harmless to the environment, turning cremation into a burial process, sparing nature.

The problem was solved by creating a method for the production of a decomposable burial urn, including preparation of source material and submission to a 3D printer for printing the urn. According to the invention, the preparation of the starting material is the preparation of a composite material and its mixing with water in a ratio of 10: 1. The composite material is obtained by mechanical mixing of silica, dialum trioxide, ferric trioxide, calcium oxide and sodium oxide. This is followed by filling the 3D printer container with the finished source material and sealing it. The next operation of the method is to generate a file for the 3D printer, corresponding to the desired shape of the urn and its printing in the time range from one to twelve hours. The printed urn is removed from the 3D printer and manually reshaped, after which the finished urn is hardened by drying. A dividing element corresponding to the cross section of the desired shape of the urn is made.

The problem is solved by creating by the method a funerary degradable urn, which is an open vessel with a separating element located in it. The vessel and the separating element are made of a composite material comprising silica, dialum trioxide, ferrous trioxide, calcium oxide and sodium oxide. The separating element is located parallel to the bottom of the vessel, so that a volume is formed in the lower part of the vessel, representing not more than 40% of the volume of the vessel. The vessel may be in the shape of either a cylinder, or a prism, or a cone, or a closed shell, or another irregular shape.

The composition of the composite material includes the components in the following weight percentages: silica is from 65 to 75 wt. %; dialuminium trioxide is from 18 to 22 wt. %; ferric trioxide is 0.5 wt. %; calcium oxide is from 10 to 15 wt. % and sodium oxide is 3 wt. %.

Another composition of the composite material is possible, in which the components are in the following weight percentages: the silica is from 45 to 55 wt. %; dialuminium trioxide is from 10 to 12 wt. %; ferric trioxide is 0.5 wt. %; calcium oxide is from 6 to 10 wt. %; sodium oxide is 3 wt. %, and contains fireclay 30 wt. %.

Descriptions of issued patents for inventions № 07.2 / 31.07.2020

In a preferred embodiment of the urn, the composition of the composite material comprises the following components in the respective weight percentages: the silica is 48 wt. %; dialuminium trioxide is 11 wt. %; ferric trioxide is 0.5 wt. %; calcium oxide is 7.5 wt. %; sodium oxide is 3 wt. % and fireclay is 30 wt. %.

The advantage of the decomposable burial urn, created by the method, is that it is ecologically clean and harmless to the environment. It is light, easily portable and does not require any special skills for planting. The use of the urn created in this way helps the cemetery parks to solve the problem of lack of space.

Explanation of the attached figure

The present invention is illustrated in the attached figure 1, which represents a possible variant embodiment of a decomposable burial urn.

Examples of the invention

The developed method for the production of a decomposable urn includes the preparation of source material and the submission to a 3D printer for printing the urn.

The printer that can be used is DELTA 3D CLAY PRINTER. The print area of the printer is 30/30/50 cm length / width / height. The nozzle of the extruder is in two sizes 0.3 mm and 0.5 mm, which size determines the wall thickness of the printed product.

The preparation of the starting material is the preparation of a composite material and its mixing with water in a ratio of 10: 1.

The composite material is obtained by mechanical mixing of silica, dialum trioxide, ferric trioxide, calcium oxide and sodium oxide. An embodiment of the composite material is also possible, which includes, in addition to the indicated components, fireclay. To obtain a ready-made starting material, the composite material is kneaded so as to acquire the consistency of clay, and liquefied with the addition of water. The prepared source material is used to fill the container of the 3D printer, which is hermetically sealed. A file corresponding to the desired urn shape is generated for the 3D printer. The time for printing the urn is from one to twelve hours, depending on its size and shape. After removing the urn from the 3D printer, it is manually reshaped and allowed to harden by drying without further firing or blowing. This usually takes up to three days. A dividing element corresponding to the cross section of the desired shape of the urn is also made.

The burial urn made according to the method is an open vessel 1 with a separating element 2 located in it, the vessel 1 and the separating element 2 being made of a composite material. The composite material includes 48 wt. %, silica, 11 wt. % dialuminium trioxide, 0.5 wt. % ferric trioxide, 7.5 wt. % calcium oxide, 3 wt. % sodium oxide, and 30 wt. % fireclay. The composite material is kneaded and liquefied by adding water in a ratio of 10: 1. The dividing element 2 is arranged parallel to the bottom 3 of the vessel 1, so that a volume is formed in the lower part of the vessel 1, representing not more than 40% of the volume of the vessel 1. The vessel 1 of the urn may be cylindrical in shape.

The mortal powder is placed in the urn made according to the created method and the separating element 2 is placed above it. By placing the degradable urn in the ground, it is possible to plant a tree of your choice to grow, turning the burial process through cremation into an ecological process. The urn decomposes from the natural moisture in the soil and provides the roots of the tree with the space, soil and moisture needed for the tree to grow for years.
