Definitions

  • the present invention relates, in general, to an isinglass-based fine powder composition for use in the production of completely biodegradable disposable tableware, and, more particularly, to a composition for use in the production of completely biodegradable disposable tableware, in which isinglass or a mixture of isinglass and starch paste is used as a binding agent, so that tableware can be produced at a high forming rate in the production of the tableware due to the gradual setting speed of the isinglass, thereby increasing the production efficiency of the tableware, so that it is possible to form tableware having complicated shapes, and so that the tableware is easily, naturally and completely decomposed through simple burial after use, thus being harmless to the environment.
  • Background Art
  • tableware As humans' lives and culture become complicated and diversified due to the overall development of industry and economy, various types of disposable tableware capable of allowing time to be saved are produced and used.
  • the types of tableware include disposable containers such as spoons, cups, dishes, lunch boxes, etc.
  • pulp material is produced with the surface thereof coated with a waterproof material such as vinyl.
  • the pulp material has problems in that it is regarded as a major cause of environmental pollution, so that the use of the pulp material coated with waterproof material is limited due to environmental restrictions, and there is inconvenience in which shops using such tableware must separate the pulp material after use.
  • Examples of using grain powder include a method of forming, freezing and coating the dough of a mixture of wheat flour, starch, baking powder and salt (Korean Patent Publication No. 1996-6565), and a method of maturing, extruding, forming and freeze- drying dough that is obtained by mixing primary ingredients, including the starch of grain and wheat flour, and auxiliary ingredients, including sugar, spice, and yeast, with refined water at an appropriate temperature (Korean Patent Unexamined Publication No. 1999-47173).
  • examples of using the epidermis of grains include a method of producing products by stirring, forming and coating the pulverized epidermis of rice, barley, millet, and Indian millet, water, and starch (Korean Patent Application No. 1999-55567), and a method of producing products by adding edible glue to vegetable particles obtained by pulverizing cornstalks and various testae and used as base material, stirring them, and compressing them using a forming agent (Korean Patent Application No. 1999-37967).
  • an object of the present invention is to provide an isinglass-based fine powder composition for use in the production of completely biodegradable disposable tableware, which allows tableware to be produced at a high forming rate due to the gradual setting speed of isinglass in the production of disposable tableware, thereby increasing production efficiency, which enables tableware having complicated shapes to be formed due to the gradual setting speed, and which allows tableware to be easily and naturally dissolved through simple burial after the use of disposable tableware.
  • the present invention provides a composition, in which isinglass can be easily converted into a gel state because it is water-soluble, and the setting time of isinglass is longer than those of other natural glues, such as oxhide glue, starch paste, bone glue, and insect glue, so that formability is provided to a composition, including isinglass, so as to allow the composition to be freely formed for a sufficient time period. Accordingly, tableware can be produced at a high forming rate in the production of the tableware due to the gradual setting speed of isinglass, thereby increasing production efficiency and enabling the forming of tableware having complicated shapes. Furthermore, the composition is characterized in that it is completely decomposed even through simple burial after use, so that it is not only harmless to the environment but is also converted into compost.
  • composition ratio the present invention characterized in that
  • the present invention is characterized in that, in order to adjust the setting time of isinglass, starch paste is added, and thus 10 to 30 weight percent isinglass, 5 to 15 weight percent starch paste and the remaining weight percent natural cellulose are included.
  • the natural cellulose is one or more selected from the group consisting of wood, grass, grain husks, fruit peel, and grain powder. Best Mode for Carrying Out the Invention
  • Fine power for use in the production of completely biodegradable disposable tableware according to the present invention is characterized by including 10 to 30 weight percent isinglass and the remaining weight percent natural cellulose. That is, the present invention is characterized in that isinglass can be easily converted into a gel state because it is water-soluble, and the setting time of isinglass is longer than those of other natural glues, such as oxhide glue, starch paste, bone glue, and insect glue, so that formability is provided to a composition, including isinglass, so as to allow the composition to be freely formed for a sufficient time period.

  • tableware can be produced at a high forming rate in the production of the tableware due to the gradual setting speed of isinglass, thereby increasing production efficiency and enabling the forming of tableware having complicated shapes. Furthermore, it is completely decomposed even through simple burial after use, so that it is not only harmless to the environment but is also converted into compost.
  • the isinglass used in the present invention is glue that is made from the bladders of fish.
  • Isinglass is a traditional natural organic bonding agent that has been used to additionally adhere wood or to adhere the hone pieces of mother-of-pearl work for a long time in the production of woodwork because it has adhesive force (bonding force) stronger than that of oxhide glue.
  • Isinglass was the most widely used kind of Korean traditional glue before oxhide glue or chemical glue was generalized.
  • a process of producing isinglass is performed by eliminating impurities, such as protein or fat, from raw materials, immersing them in the washing water of rice or boiling them in water using a low fire, and then drying them in the shade, in a manner similar to that for oxhide glue.
  • Isinglass is stored in a solid state, and is liquefied by melting solid isinglass using a fire at the time of use. When solid isinglass is melted, the solid isinglass is heated in a water bath without coming into direct contact with flame. Thereafter, it is used after being filtered using a clean and coarse cloth.
  • isinglass made from the air bladders of sciaenoid fish have advantages in that it exhibits a sufficiently strong binding force to be traditionally used to manufacture Korean bows or fans and in that it has a sufficient setting period to enable elaborate work.
  • the heating temperature, the heating time and the amount of water added, which are employed to liquefy the isinglass, are all known to those sufficiently skilled in the art that they can perform work using isinglass. Since the isinglass is glue that has been traditionally and widely used in Korea, it is familiar to Koreans.
  • the present invention is not limited to particular liquefaction conditions for isinglass.
  • the setting time can be somewhat freely controlled by controlling the concentration through the control of the amount of water.
  • the isinglass occupies 10 to 30 weight percent in the fine powder composition for use in the production of disposable biodegradable tableware according to the present invention.
  • the reasons why the percentage of isinglass is limited as stated above is that, in the case where the percentage of the isinglass is less than 10 weight percent, problems may arise in that forming is not freely performed due to the poor fluidity of the composition according to the present invention, and the composition is thus easily broken due to weak binding force, and, in contrast, in the case where the percentage of the isinglass exceeds 30 weight percent, problems may arise in that the unit cost of products is not economic, and thus practicality is lowered.
  • the remaining ingredient is natural cellulose.
  • This natural cellulose in itself does not exhibit any binding force, and is material that is set using another glue and then constitutes a hard portion capable of improving physical properties.
  • the natural cellulose is one or more selected from the group consisting of wood, grass, grain husks, fruit peel, and grain powder.
  • the wood is the thin skins or broken pieces of one or more selected from the group consisting of the various woods of a pine tree and a black oak, preferably sawdust.
  • the grass is the thin skins or broken pieces of one or more grasses selected from the group consisting of rice straw, beanstalks, and sesame stalks.
  • the grain husks are one or more selected from the group consisting of bean hull, rice bran, millet husks, and Indian millet husks.
  • the fruit peel is one or more selected from the group consisting of the peels of fruit or seeds such as oil- seed cakes, the peels of oranges, and the peels of apples.
  • the grain powder is one or more selected from the group consisting of rice flour, corn flour, and wheat flour.
  • the grain powder may be any kind of grain powder, it is preferable to reuse grain powder the quality of which was partially deteriorated or the product value of which was reduced, from an economic standpoint.
  • a composition can be obtained by mixing isinglass with starch paste.
  • starch paste is added is that not only is binding force not significantly reduced when the starch paste is mixed with the isinglass, but also the starch paste, together with the isinglass, acts to reduce setting time compared to the case where the isinglass is used alone, so that it is possible to adjust the setting time, thereby being capable of producing disposable tableware economically.
  • the present invention ensures a long setting time, and thus allows artistic tableware to be formed, in which case the tableware is formed in the state in which the degree of dryness of the isinglass is equal to or greater than 20, and thus the isinglass is converted into gel.
  • Such tableware may be used in the state in which it is completely dried after being formed.
  • the present invention ensures a long setting time, and thus can be used to produce moldings, which have formative beauty as interior construction material.
  • work may be conducted in the state where the degree of dryness is adjusted to 20 or greater and material is in a gel state.
  • the composition is formed into powder, in which the degree of dryness of the isinglass is about 10-20, and the powder is fed to a high-temperature compression molding machine and is compression-molded into disposable tableware in large quantities.
  • the tableware is composed of natural materials, so that it can be easily and naturally dissolved and decomposed through simple burial, thus not causing environmental pollution.
  • such tableware does not affect the cultivation of crops in land or the appearance of land because the tableware easily loses its shape and collapses thanks to the use of isinglass, and the natural cellulose itself, which forms most of the composition, can function as compost.
  • the composition of the present invention is converted into ceramic through high-temperature compression by pressing upper and lower molds, which are formed to conform to the shape of specific tableware so as to produce disposable tableware in large quantities, using a press machine, so that the tableware has an advantage in that it can be used to cook food in a microwave oven while preventing the food from being burned.
  • the fine powder composition of the present invention is fed into the cavity of molds, which are formed to conform to the shape of specific tableware, and is compression-molded.
  • the compression conditions under which disposable tableware can be converted into ceramic in the compression molding, include a temperature range of 15O-18O7C, and a compression pressure range of 1000-1500 tons based on a mold having dimensions of 1300 mm- 1300 mm.
  • the temperature can be maintained because the mold is equipped with a heating device, and the compression pressure changes in linear proportion to the change in the size of a mold.
  • isinglass or starch paste does not have a dryness degree range of 10-20, unlike that in mass production, but is used in a gel state, having a dryness degree greater than 20.
  • the embodiments were worked with the content of water adjusted to the same level by an operator.
  • a composition according to the present invention was obtained by mixing 20 weight percent isinglass with 60 weight percent rice husks and 20 weight percent finely sliced rice straw, which are forms of natural cellulose.
  • Embodiment 3 (Embodiment 3) This embodiment was implemented in the same manner as Embodiment 1, except that 10 weight percent isinglass and 10 weight percent starch paste were used.
  • Embodiment 4 (Embodiment 4) This embodiment was implemented in the same manner as Embodiment 1, except that 5 weight percent isinglass and 15 weight percent starch paste were used.
  • the above-described present invention is an invention that provides a composition for use in the production of completely biodegradable disposable tableware, in which isinglass or a mixture of isinglass and starch paste is used as a binding agent, so that tableware can be produced at a high forming rate in the production of the tableware due to the gradual setting speed of the isinglass, thereby increasing the production efficiency of the tableware, so that it is possible to form tableware having complicated shapes, and so that the tableware is easily, naturally and completely decomposed through simple burial after use, thus not only being harmless to the environment but also being reused as compost.
