In order to manufacture biodegradable synthetic resins, seaweeds such as maban, loot, seaweed and kelp are mainly used. In the present invention, extract pectin and agar from seaweeds, and extract starch from fruit peels such as apples, tangerines, pears, and after mixing the extracted pectin, agar, and starch to produce a resin chip, by injection molding method in a mold Produce a buffer. Preferably, the raw material is extracted using a mother board collected in a large amount on the south coast and Jeju Island, and a tangerine peel produced in a large amount on Jeju Island.

First, in order to extract the pectin from the algae, the algae that have been pushed to the beach are collected and then prepared into small pieces through drying and grinding. (S102)

In addition, hydrochloric acid (HCl) or sulfuric acid (H ₂ SO ₄ ), which is an acidic solution, is added to the seaweed crushed into pieces and then heated. (S104) The heating process is carried out at a temperature of 60 ° C. to 70 ° C. for 2 hours, or A method of heating for 15 minutes in the range can be used. When a small amount of alcohol is added to the algae to which the acid is added, pectin, which is a polysaccharide, is extracted and precipitated.

Through this process, the precipitated material is separated to extract pectin. (S106)

In addition, a basic solution is added to the algae crushed into pieces to extract agar from the algae, and then heated, typically sodium hydroxide (NaOH) is added. (S108) The heating process is performed at a temperature of 90 ° C to 110 ° C. Extract while heating for about an hour.

Then, the foreign matter is removed through the filtration process and the remaining agar is separated.

The fruit peels are collected, washed, dried, and crushed to obtain a tangerine peel in the form of crushed pieces, and then dried by heating with sodium metabisulfite (Sodium Metabisulfite) solution. Drying is completed to crush the hardened fruit peel into fine particles to produce a starch powder. (S112)

Through this process, pectin, agar and starch can be extracted. Finally, pectin, agar, and starch are mixed in an appropriate blending ratio to make a resin chip (S114), and the resin chip is put into a molding machine to make a product of a desired shape. (S116)

Through such a process, a biodegradable synthetic resin material can be manufactured.

The manufactured synthetic resin material is molded in the form of an upper buffer material 120 or a first side buffer material 122, and is injected into a mold for pulp mold to form an inner cover 108.

In order to form the inner cover 108, a tape-shaped bottom surface 108a is introduced into the mold, and the upper buffer 120 or the first side buffer 122 is placed thereon. The inner cover 108 into which the cushioning material is inserted can be manufactured by molding the pulp body 108b by injecting pulp into the mold.

On the other hand, Figure 13 is a cross-sectional view showing a state in which the cushioning material is inserted into the egg yolk.

When the cushioning material is inserted into the inner cover 108, the shock applied from the upper side can be absorbed, but the impact applied from the lower side when the egg tray 100 is placed on the bottom surface cannot be prevented. In the present invention, a separate buffer is used to absorb the impact of the lower side.

The egg seat 102 on which the egg 30 is placed is made of a general pulp mold and manufactured to have a certain thickness. The lower buffer 124 and the second side buffer 126 is inserted into the inner seat 102 forming the bottom.

The lower buffer 124 is inserted into the vertical bottom surface of the egg seat 102 to absorb the impact applied from the vertical bottom of the egg 30. And the second side buffer 126 is inserted into the inclined surface of the lower side of the egg seat 102 to absorb the impact applied obliquely from the lower side of the egg 30.

Materials and methods of manufacturing the lower buffer 124 and the second side buffer 126 are the same as the upper buffer 120 and the first side buffer 122 of the above-described embodiment.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the above-described technical configuration of the present invention may be embodied by those skilled in the art to which the present invention pertains without changing the technical spirit or essential features of the present invention.
