The lower side of the side part 26 abuts on the corner part 10 h of the bottom part 10.

  A method for manufacturing the paper container 5 having the above configuration will be described. As shown in FIG. 4, the overall manufacturing process flow is to manufacture paper used for the corrugated cardboard material constituting the paper container 5 (S11, paper manufacturing process), and to manufacture the corrugated cardboard material from the manufactured paper. (S12, cardboard manufacturing process), a paper container is manufactured from the manufactured cardboard material (S13, box making process).

  Here, in the paper manufacturing process, the paper used for the liner A and the paper used for the core B are manufactured by the same method as before.

  Moreover, the manufacturing process of the liner C mixed with soot is configured as shown in FIG. 5 and includes a pulping process (may be referred to as “pulp manufacturing process”) (S21) and a paper manufacturing process (S22). The conversion step is configured by each step shown in FIG.

  That is, first, in the used paper processing step (S31), the used paper as the pulping material is put into the pulper, and the adhering matter such as ink and paper fibers adhering to the used paper are disaggregated, and then the dust is collected by the screen. After that, the dust is removed, and then it is put into a deck machine to remove chemicals such as synthetic glue and surfactant contained in the waste paper.

  Then, in the disaggregation step (S32), the used paper is again put into the pulper to dissociate the deposits and the paper fibers, and further disaggregates the fibers that have not been disaggregated by the pulper by a seven finaler or a top finalizer.

  Thereafter, the waste paper separated for each fiber of the paper is put into a refiner in the beating step (S33), and the fibers of the paper are beaten or crushed so that the fibers are easily entangled. In addition, the process from the said waste paper processing process (S31) to the beating process (S33) corresponds to "the pre-formation process which makes a pulp material into the state of the paper fiber before preparation".

  Thereafter, in the preparation step (S34), the beaten waste paper (that is, paper fibers (pulp) before preparation), filler, dye / pigment, chemicals, and straw are put into a mixer and mixed. The cocoon in this case is specifically the leaves after extracting the extract from the cocoon (specifically, Kumazasa) leaves and / or cocoons (specifically, crushed leaves and / or crushed cocoons). This is a residue, for example, a residue after squeezing crushed Kumazasa leaves and / or straw buds to extract the extract. More specifically, it may be a residue after washing Kumazasa leaves with cold water and then coarsely pulverizing and pressing them. It may be a residue after obtaining the extract. The amount of the residue after extracting the extract from bamboo leaves and / or straw is 10 to 20% of the weight of the beaten waste paper (that is, paper fiber). For example, 10 to 20 kg of residue is added to 100 kg of beaten used paper. If the amount of the residue is more than 20% of the weight of the paper fiber, the function as paper (for example, the strength of the paper) is not sufficient, and if it is less than 10%, the antibacterial / deodorizing effect Is not sufficient, it is preferable that the content be 10 to 20% as described above.

  Fillers include natural or synthetic white pigments (eg, clay (clay, clay), kaolin, calcium carbonate, titanium dioxide) to improve paper whiteness, opacity, texture, and surface smoothness. In order to prevent ink loss during printing. Moreover, as a chemical | medical agent, starch and PAM (polyacrylamide) are mentioned as a chemical | medical agent which raises the intensity | strength of paper, A wet paper strength agent is mentioned as a chemical | medical agent which raises the intensity | strength (wet paper strength) when wet.

  As described above, the pulp is manufactured through the waste paper processing step, the disaggregation step, the beating step, and the preparation step. It can be said that the above pulping process is different from the conventional pulping process in that koji is mixed in the preparation process.

  In the above pulping process, the treatment by the decker machine may be omitted, the disaggregation process and the beating process may be omitted, and a process of adsorbing ink to the foam by a flowator may be provided. . That is, for example, pulping may be performed in the order of the pulper, the floater, the screen, and the preparation.

  In addition, the above is the case of recycled pulp that is pulped from waste paper, but chemical pulp or pulping material that forms and pulps fibers extracted from wood pieces (chips) as pulping materials using chemicals The wood pieces (chips) may be crushed with a refiner, and then pulped with mechanical pulp that forms and pulps the fibers obtained by removing dust with a screen and bleaching. Even in that case, in the preparation step at the end of the pulping step, the resulting fiber is mixed with the dye or pigment, and the residue after extracting the extract from the bamboo leaves or straw during the preparation Mix things.

  When the pulp is produced as described above, the process proceeds to a papermaking process (may be referred to as “papermaking process” or “papermaking process”) (S22), and papermaking (may be referred to as “papermaking” or “papermaking”) is performed. This papermaking process is performed in the same process as the conventional process. That is, in this papermaking process, processing is performed in the order of wire part, press part, dry part, size press, and calendar. In other words, in the wire part, water is cut off while the fibers are entangled on the net to form a paper layer. In the press part, the paper layer is placed on the felt and dehydrated between two rolls. In the dry part, Press the paper against a steam-heated iron dryer to dry it, and in the size press, apply chemicals to the surface of the paper to make it suitable for printing, and in the calendar, the paper thickness passes through the paper between the iron rolls. Smooth the surface of the paper. After that, the reel is wound up and cut with a winder or a cutter. Since the liner C is paperboard, the paper part is formed in multiple layers in the wire part. As described above, the paper for the liner C is manufactured. In the manufactured paper for liner C, a pattern of crushed cocoons appears, and the whole is light green due to the extract remaining in the residue.

  In addition, you may provide the coating process which coats the paper surface with a pigment etc. after a dry part in front of a calendar, and you may provide a dry part further between a size press and a calendar. In addition, a humidity control step by a paper master may be provided before winding with a reel.

  The liner A paper and the core B paper are also manufactured in the same process as described above. However, in the case of the liner A paper, no wrinkles are mixed.笹 is not mixed. Also, in the case of the paper for the core B, no wrinkles are mixed in the preparation step, and since the paper for the core is formed thin, in the wire part, the paper layer is one layer ( A single layer).

  As described above, when the paper for the liner A, the paper for the core B, and the paper for the liner C are manufactured, a corrugated board material is manufactured using these papers (S12).

  When producing the corrugated board material, it is produced by the same method as that of the prior art, and specifically by a corrugator (corrugating machine). This corrugator has the same configuration as that of a normal corrugator, and means for feeding out the paper for the liner A, means for feeding out the paper for the core B, means for feeding out the paper for the liner C, and preheat each paper. A preheating roll, a set of tooth rolls for continuously forming a corrugated core from the preheated core B paper, and an adhesive is applied to the top of one surface of the formed core Single-sided corrugated paper called “single facer” by continuously bonding the first adhesive applying means, the core B coated with the adhesive, and the paper for the liner A on one of the tooth profile rolls First bonding means having a pressure-bonding roll for forming a sheet, second adhesive applying means for applying an adhesive to the top of the other side of the formed single-sided cardboard, and single-sided cardboard coated with an adhesive For paper and liner C A second laminating means arranged to dry the adhesive and complete the affixing during travel, while forming a double-sided cardboard called “double backer” by laminating with paper And a second bonding means having a number of small pressure rolls.

  A corrugated board made of the liner A, the core B, and the liner C is manufactured by the corrugator having the above configuration.

  When the corrugated board material is manufactured, the corrugated board is punched into the unfolded state shown in FIG. 2 by a die cutting apparatus such as Thomson, and then assembled into the shape of the container shown in FIG. That is, an adhesive is applied to the glue margins 18, 20, 28, and 30, and each part constituting the paper container 5 is bent to form a container shape.

  As described above, the paper container 5 is manufactured through the paper manufacturing process (S11), the cardboard manufacturing process (S12), and the box making process (S13).

  In addition, since the residue having a weight of 10 to 20% with respect to the weight of the paper fiber is mixed, in the liner C constituting the paper container 5, it is 9 to 18% by weight with respect to the weight of the entire liner C. The residue after extracting an extract from a bamboo leaf and / or a bamboo basket will be mixed.

  When the paper container 5 manufactured as described above is used, an object to be stored is stored in the paper container 5 for use. In particular, since the soot is mixed in the liner C inside the paper container 5, an antibacterial and deodorizing effect can be obtained, and it is particularly suitable when food is stored as the storage portion.

  Further, in the paper container 5, since the crushed ridge pattern appears on the inner liner C, it is possible to visually recognize that the cocoon is mixed and to provide a novel pattern. In addition, the liner C can be a light green as a whole due to the extract remaining in the residue, and can be colored with a natural pigment.

  In addition, when the paper container 5 is manufactured, the residue after the extract is extracted from Kumazasa is added in the preparation process of the pulping process in the manufacturing stage of the paper for the liner C. The process of apply | coating is unnecessary.

  In addition, since the residue is mixed during the preparation of the pulp, paper pulp resources can be saved correspondingly, and the manufacturing cost can be reduced. For example, the weight of the paper fiber is 10 to 20% of the weight of the paper fiber. By mixing the residue, paper fiber can be saved. Also, instead of using the kumazasa extract itself, the residue after extracting the extract from kumazasa leaves and straw is used, so the manufacturing cost can be reduced compared to the case where the kumazasa extract is applied, Moreover, the residue after extracting an extract from Kumazasa can be used effectively. In particular, since the residue can be used effectively, it is not necessary to dispose of the residue, so that the consumption of fossil fuel can be reduced and the generation amount of carbon dioxide can also be reduced.

  In the above description, the liner C in which the inner liner C of the paper container 5 is mixed is described as being used. However, the outer liner A may be a liner in which soot is mixed in the same manner as the liner C. In this case, the outer surface of the paper container 5 can also be antibacterial and deodorized. For example, when storing a plurality of paper containers 5 in a stacked state, the outer surface is also subjected to antibacterial / deodorizing treatment, so that the inner side of the paper container 5 positioned below the paper container 5 Can keep the surface clean. In addition, since the pattern of the crushed candy appears on the outside of the container, it can be visually recognized that the candy is mixed in, and a novel pattern can be provided. The surface can be light green and colored with natural pigments. In that case, in the production of corrugated cardboard, paper in which wrinkles are mixed in both liners is used.

  Further, instead of the inner liner of the paper container 5, a liner in which wrinkles are mixed in the outer liner may be used. Also in this case, when storing a plurality of paper containers 5 in an overlapped state, the outer surface is subjected to antibacterial / deodorizing treatment, so that the paper container located below the paper container 5 5 has no effect on the inner surface of the container, and a crushed candy pattern appears on the outside of the container, so that it can be visually confirmed that the candy is mixed. A pattern can be provided.

  In the above description, the blank constituting the paper container 5 is composed of double-sided cardboard made of the liner A, the core B, and the liner C. It may be cardboard. In that case, the liner C may be inside the container or outside the container.

  Further, in the above description, the corrugated cardboard is used to manufacture corrugated cardboard, and the corrugated cardboard is used to make a box. However, the corrugated cardboard is used without manufacturing corrugated cardboard. A paper container may be manufactured. For example, a paperboard (cardboard) mixed with straw may be manufactured, and a paper container may be manufactured using the paperboard.
