Packing container using coconut by-product, grain by-product or coffee by-product and method for producing same

Abstract

The present invention relates to a packing container using a coconut by-product, a grain by-product, or a coffee by-product, and a method for producing same. A paper packing container produced according to the present invention enables a packing container shape to be in a complete form by adjusting the moisture content of pulp of a coconut by-product, a grain by-product, or a coffee by-product, which is an eco-friendly raw material, before entering a molding process.

1 . A method for producing a packing container using a coconut by-product, a grain by-product, or a coffee by-product, the method comprising:
 filtering a raw pulp material by filtering foreign substances from the coconut by-product, the grain by-product, or the coffee by-product;   agitating the raw pulp material in water to pulp the raw pulp material into by-product pulp;   filling the inside of a storage apparatus with a pulp liquid containing the by-product pulp;   measuring moisture content of the pulp liquid inside the storage apparatus;   adjusting the moisture content of the pulp liquid to fall within a predetermined range in the case that the measured moisture content is out of the predetermined range;   filling a mold of a molding apparatus with the pulp liquid with the moisture content adjusted; and   applying pressure to the pulp liquid in the mold to produce a molded article in a shape corresponding to the mold.   
     
     
         2 . The method of  claim 1 , wherein the grain is at least one grain selected from the group consisting of rice, barley, soybean, red bean, millet, sesame, wheat and corn. 
     
     
         3 . The method of  claim 1 , wherein the adjusting of the moisture content of the pulp liquid comprises:
 reducing the moisture content of the pulp liquid to fall within the predetermined range by applying heat to the inside of the storage apparatus in the case that the moisture content is higher than the predetermined range.   
     
     
         4 . The method of  claim 3 , wherein the reducing of the moisture content by applying the heat to the inside of the storage apparatus comprises:
 halting the heat application to the inside of the storage apparatus in the case that the moisture content is reduced and becomes lower than an upper limit of the predetermined range.   
     
     
         5 . The method of  claim 1 , wherein the adjusting of the moisture content of the pulp liquid comprises:
 reducing the moisture content of the pulp liquid to fall within the predetermined range by dehydrating the pulp liquid in the case that the moisture content is higher than the predetermined range.   
     
     
         6 . The method of  claim 5 , wherein the reducing of the moisture content by dehydrating the pulp liquid comprises:
 halting the dehydration of the pulp liquid in the case that the moisture content is reduced and becomes lower than the upper limit of the predetermined range.   
     
     
         7 . The method of  claim 1 , wherein the adjusting of the moisture content of the pulp liquid comprises:
 increasing the moisture content of the pulp liquid to fall within the predetermined range by supplying liquid to the pulp liquid in the case that the moisture content is less than the predetermined range.   
     
     
         8 . The method of  claim 7 , wherein the increasing of the moisture content by supplying the liquid to the pulp liquid comprises:
 halting the liquid supply to the pulp liquid in the case that the moisture content increases and becomes higher than the lower limit of the predetermined range.   
     
     
         9 . A packing container produced according to the method of  claim 1 .
