Description

Technical Field

[0001] The present invention relates to a method for manufacturing a seat plate for product packaging and a seat plate manufactured thereby. More specifically, when manufacturing a seat plate (tray) used inside an external case to prevent damage and sway during product packaging, the present invention relates to a technology for more easily manufacturing an environmentally friendly seat plate for product packaging using paper.

Background Art

[0002] Generally, when simply packing food products such as fruits that are easily damaged by external stimuli and other products in a cardboard box, the products may be severely damaged even by slight friction or sway between the products during handling. Therefore, a packaging seat plate or egg seat manufactured in a certain shape to individually accommodate the products and stably seat them is used.

[0003] A normal packaging seat plate is formed and manufactured using a synthetic resin raw material in a form corresponding to the outer shape of the product to be packaged.

[0004] As an example of the prior art, Korean Registered Utility Model No. 20-0264461 discloses a fruit egg seat made of polyethylene terephthalate (PET) material, which includes a main body with an extension formed on the outer edge, an egg seat groove integrally formed on the upper surface of the main body for storing fruits, an air induction groove formed in at least one of the circumferential directions of the inner surface of the egg seat groove in the shape of a groove or a protrusion, and an open groove formed at the boundary where the egg seat grooves are adjacent to each other.

[0005] As another example, Korean Registered Utility Model 20-0447103 discloses a fruit egg seat made of synthetic resin, which includes a support body installed inside a fruit box, a plurality of seating grooves formed on the support body for individually storing fruits, a recessed groove formed in the seating groove so that a part of the bottom surface of the stored fruit communicates with the external air, and a cushion part formed by a region where the recessed groove protrudes downward from the bottom surface of the seating groove of the support body.

[0006] On the one hand, recently, for the recycling of paper waste, technologies for manufacturing seat boards or egg seats using pulp as a raw material have been provided. For example, in Korean Registered Patent No. 10-0561234, after thoroughly washing the pulp and then dissolving it, a chemical addition step, a stirring process step, a step of shaping the stirred pulp, a step of drying the shaped product, and in the step of shaping through a functional additive addition step after the stirring process step, a water-soluble liquid functional additive obtained by diluting a powder-form additive in which a silver ion-based inorganic antibacterial agent and titanium oxide are blended in distilled water is added to the raw material in which the chemicals and pulp are stirred, constituting a method for manufacturing an egg seat using a pulp mold.

Summary of the Invention

Problems to be Solved by the Invention

[0008] Most of the seat boards or egg seats for packaging to which the above-mentioned conventional technologies are applied are products mainly molded using raw materials of synthetic resins or foamed resins.

[0009] However, although the seat board for packaging manufactured from the raw material of synthetic resin has the advantage that the processing of the raw material and the manufacturing process are relatively simple, due to the characteristics of the packaging material that is discarded after being used once, there is a drawback that environmental pollution is caused by the processing and disposal of the synthetic raw material products.

[0010] Moreover, in recent years, due to worldwide regulatory policies on the use of plastic containers, including in South Korea, the consumption of conventional synthetic resin seat plates is expected to significantly decrease, and there is also a problem that it is not helpful for achieving carbon neutrality.

[0011] Due to such problems, recently, seat plates or egg seats manufactured by recycling paper scraps have been developed and provided. However, at present, most processes other than the molding process are done manually, and constructing and operating facilities for carrying out the papermaking process after dissolving in pulp requires a great deal of labor and cost, so there are problems of low workability, productivity, and economy.

[0012] In addition, in the process of manufacturing paper by recycling pulp as in the past, it is inevitable to add various chemical agents, so separate facilities and processes for treating the generated wastewater are required, which not only causes deterioration of the working environment, but also the produced base paper has no elongation rate, so it is often torn during the process of forming into the shape of an egg seat, and the quality control and handling are difficult.

Means for Solving the Problems

[0013] Therefore, the present invention was devised to solve the problems of the prior art as described above. A first base paper cutting step (S10) of cutting a first base paper (110) according to a target standard so as to form the upper surface of the seat plate, and cutting a first slit (131) for each arrangement area of the seating portion (130); A second base paper cutting step (S20) of cutting a second base paper (120) according to a standard corresponding to the first base paper (110) cut in the first base paper cutting step (S10) so as to form the lower surface of the seat plate, and cutting a second slit (133) for each arrangement area of the seating portion (130); A bonding step (S30) of the first and second base papers of stacking and bonding the first base paper (110) and the second base paper (120) cut in the first base paper cutting step (S10) and the second base paper cutting step (S20) vertically; In the paper seat plate forming step (S40), place the first and second base papers laminated in the lamination step (S30) of the first and second base papers into a seat plate forming die, and form the seating portion (130) and the edge portion (140). In the paper seat plate hardening step (S50), dry and cure the seat plate formed in the paper seat plate forming step (S40) at room temperature to integrate it. In the paper seat plate cutting step (S60), place the seat plate integrated in the paper seat plate hardening step (S50) into a cutting mold, cut the outer periphery of the edge portion (140), and take out the finished seat plate. By including this method, the purpose of more easily manufacturing an environmentally friendly product packaging seat plate using paper can be achieved.

Advantages of the Invention

[0014] The present invention provides a method for more easily manufacturing an environmentally friendly product packaging seat plate using paper when manufacturing a seat plate used inside an external case to prevent damage and sway during product packaging.

[0015] Therefore, compared with the conventional manufacturing technology of seat plates or egg seats using synthetic resins or foamed resins, the present invention can significantly reduce the environmental pollution induction and the economic burden associated with waste treatment, and can also meet the recent plastic container use regulation policies and carbon neutrality.

[0016] In addition, different from the conventional manufacturing technology of seat plates or egg seats using pulp raw materials, the present invention applies the manufactured paper itself as a base paper to the die used in the existing seat plate manufacturing, and realizes stable formability, thereby saving the production cost by omitting the complicated papermaking process as in the prior art, and also eliminating the need to add various chemicals used in the pulp dissolution and papermaking processes. Therefore, there is an advantage that a high-quality packaging seat plate made of more environmentally friendly paper raw materials can be manufactured.

[0018] Hereinafter, the manufacturing method of the seat board for product packaging of the present invention and the configuration and operation according to a preferred embodiment of the seat board manufactured thereby will be described in detail with reference to the accompanying drawings as follows. In the following description, specific descriptions regarding parts that can be easily implemented by an ordinary technician in the technical field may be omitted. It should be noted that the following description is given by way of preferred embodiments of the present invention, and the present invention is not limited by the following embodiments, and it is natural to say that various modifications may be provided without departing from the scope of the present invention.

[0019] FIG. 1 is a process flow diagram showing the manufacturing method of the seat board for product packaging according to the present invention, FIG. 2 is an exemplary diagram of the first base paper cutting step and the second base paper cutting step in the manufacturing method of the seat board for product packaging according to the present invention, FIG. 3 is an exemplary diagram of the pasting step of the first and second base papers in the manufacturing method of the seat board for product packaging according to the present invention, FIG. 4 is a plan view and a side view of the seat board for product packaging manufactured by the manufacturing method of the seat board for product packaging according to an embodiment of the present invention, and FIG. 5 is a perspective view of the seat board for product packaging manufactured by the manufacturing method of the seat board for product packaging according to an embodiment of the present invention.

[0020] The manufacturing method of the seat board for product packaging to which the technology of the present invention is applied and the seat board manufactured thereby clarify that when manufacturing a seat board used inside an external case to prevent damage and rocking during product packaging, it is a technology that enables easier manufacturing of an environmentally friendly seat board for product packaging using paper.

[0021] The manufacturing method of the seat board for product packaging of the present invention therefor includes a first base paper 110 manufacturing stage, a second base paper 120 manufacturing stage, a bonding stage (S30) of the first and second base papers, a paper seat board forming stage (S40), a paper seat board hardening stage (S50), and a paper seat board cutting stage (S60), and the details are as follows.

[0022] The first base paper cutting stage (S10) is a stage of cutting the first base paper 110 to a target standard so as to form the upper surface of the seat board and cutting a first slit 131 for each arrangement area of the seating part 130.

[0023] In the first base paper cutting stage (S10), the already manufactured first base paper 110 is cut to a rectangular shape according to the standard, for example, and a first slit 131 is cut at a position corresponding to the arrangement area of the seating part 130 on which the product to be packaged is stably placed. In an embodiment of the present invention, since the seating parts 130 are arranged in parallel at 12 locations on the rectangular first base paper 110, the first slit 131 is cut for each such area.

[0024] As shown in FIG. 2, in the first base paper cutting stage (S10), the first slit 131 is cut in an X shape or in a shape of a linear (*) intersecting radially.

[0025] In the first base paper cutting step (S10), when cutting the first slit 131, the first base paper 110 and the second base paper 120 to be cut in the second base paper cutting step (S20) described below are stacked one above the other, and cutting is performed such that the first slit 131 and the second slit 133 are offset from each other as shown in FIG. 3. For example, when forming the first slit 131 in an X shape, the second slit 133 is cut in a cross (+) shape so as to be offset from each other.

[0026] In the first base paper cutting step (S10), a circular or radially polygonal first slit center hole 132 is formed by punching at the center point of the first slit 131.

[0027] Since the first slit 131 will form a sharp portion at the center when expanded by a mold in the paper seat plate forming step (S40) described below, in the first base paper cutting step (S10), when cutting the first slit 131, a circular or radially polygonal, for example, a hexagonal first slit center hole 132 with a curved straight portion as in the embodiment of the present invention is punched at the center point to prevent the formation of a sharp portion.

[0028] The second base paper cutting step (S20) is a step of cutting the second base paper 120 according to a standard corresponding to the first base paper 110 cut in the first base paper cutting step (S10) so as to form the lower surface of the seat plate, and cutting the second slit 133 for each arrangement area of the seating portion 130.

[0029] In the second base paper cutting step (S20), the already manufactured second base paper 120 is cut according to a standard, for example, into a square shape, but the second slit 133 is cut at a position corresponding to the arrangement area of the seating portion 130 on which the product to be packed is stably placed. In the embodiment of the present invention, since the seating portions 130 are arranged in parallel at 12 locations on the rectangular second base paper 120, the second slit 133 is cut for each corresponding area.

[0030] As shown in FIG. 2, in the second base paper cutting step (S20), the second slit 133 is cut into a shape of an X (×) or a linear (*) shape intersecting radially.

[0031] In the second base paper cutting step (S20), when cutting the second slit 133, the second base paper 120 and the first base paper 110 cut in the first base paper cutting step (S10) are stacked one on top of the other, and the second slit 133 and the first slit 131 are cut so as to be offset from each other as shown in FIG. 3. For example, when the first slit 131 is formed in an X (×) shape, the second slit 133 is cut in a cross (+) shape so as to be disengaged from each other.

[0032] In the second base paper cutting step (S20), a circular or radially polygonal second slit center hole 134 is formed by punching at the center point of the second slit 133.

[0033] Since the second slit 133 will form a sharp part at the center when expanded by a mold in the paper seat plate forming step (S40) described later, in the second base paper cutting step (S20), when cutting the second slit 133, a circular or radially polygonal, for example, a hexagonal second slit center hole 134 with a curved straight part as in the embodiment of the present invention is punched at the center point to prevent the formation of a sharp part.

[0034] The step of bonding the first and second base papers (S30) is a step of stacking and bonding the first base paper 110 and the second base paper 120 cut in the first base paper cutting step (S10) and the second base paper cutting step (S20) one on top of the other.

[0035] In the step of bonding the first and second base papers (S30), in order to bond the first base paper 110 and the second base paper 120 cut to the same standard one on top of the other, a natural adhesive is applied to the lower surface of the first base paper 110 and the upper surface of the second base paper 120, and both are bonded by temporary adhesion.

[0036] In the step (S30) of bonding the first and second base papers, a natural adhesive, such as a starch adhesive, is applied and temporarily bonded so that the first base paper 110 and the second base paper 120 are bonded to such an extent that they do not move in the paper seat plate forming step (S40) described later. As shown in FIG. 3, in the bonded state, the first slit 131 and the second slit 133 are positioned so as to be mutually disengaged.

[0037] The first base paper 110 and the second base paper 120 are completely integrated through the paper seat plate forming step (S40) and the paper seat plate hardening step (S50) performed at a high temperature.

[0038] The paper seat plate forming step (S40) is a step of putting the first and second base papers bonded in the step (S30) of bonding the first and second base papers into a seat plate forming die and forming the seating portion 130 and the edge portion 140.

[0039] In the paper seat plate forming step (S40), the bonded first and second base papers are placed between the upper die and the lower die, and heated and pressed to recess-mold a plurality of seating portions 130 in the seat plate body 100 and form an edge portion 140 on the outer periphery. Between the seating portions 130, a rib portion for partitioning a space is formed, and if necessary, a predetermined curved surface shape may be formed on the rib portion to impart a stronger supporting force to the seat plate body 100.

[0040] In the paper seat plate forming step (S40), heating and pressing are performed at a temperature of 180°C to 220°C, and as shown in FIGS. 4 and 5, the first slit 131 and the second slit 133 of the seating portion 130 are recess-molded at a certain depth while radially expanding.

[0041] In the paper seat plate forming step (S40), after being cut in the first base paper cutting step (S10) and the second base paper cutting step (S20), the first slits 131 and the second slits 133 of the first base paper 110 and the second base paper 120 temporarily adhered by a natural adhesive in the pasting step (S30) of the first and second base papers are deployed at displaced positions with respect to each other in the process of forming the seating portion 130 by a high-temperature mold to form the inner peripheral surface and the bottom surface of the seating portion 130, and an edge portion 140 is formed along the outer periphery of the seat plate body 100.

[0042] When the temperature range is exceeded in the paper seat plate forming step (S40), the first slits 131 and the second slits 133 may burst during the deployment process, or the pasted state may not be maintained.

[0043] The paper seat plate hardening step (S50) is a step of drying and hardening the seat plate formed in the paper seat plate forming step (S40) at room temperature to integrate it.

[0044] In the paper seat plate hardening step (S50), the seat plate formed by a high-temperature heating press is dried and hardened, and the first base paper 110 and the second base paper 120 are pasted together to complete the target shape.

[0045] The paper seat plate cutting step (S60) is a step of putting the seat plate integrated in the paper seat plate hardening step (S50) into a cutting mold, cutting the outer periphery of the edge portion 140, and taking out the finished seat plate.

[0046] In the paper seat plate cutting step (S60), the formed seat plate is seated on a cutting mold, and the cutter is lifted and lowered to cut the outer periphery of the edge of the seat plate to finish, thereby forming a finished seat plate.

[0047] A seat plate manufactured by the manufacturing method of a seat plate for product packaging to which the technology of the present invention as described above is applied includes a seating portion 130 and an edge portion 140 in a seat plate body 100 formed by pasting a first base paper 110 and a second base paper 120 together.

[0048] The seat plate body 100 is formed by laminating a plurality of layers of a first base paper 110 and a second base paper 120 vertically and integrally bonding them. A plurality of seating portions 130 for stably placing the product to be packaged are arranged at the center, and an edge portion 140 is formed on the outer periphery. In an embodiment of the present invention, two layers of base paper are applied vertically, but depending on the material and thickness of the paper, two or more layers of base paper may be laminated to form the seat plate body 100.

[0049] The first base paper 110 and the second base paper 120 constituting the seat plate body 100 are cut and formed into a shape of a first slit 131 and a second slit 133 intersecting in an X (×) shape or a linear (*) shape radially for each arrangement area of the seating portion 130. The first slit 131 and the second slit 133 are formed so that when the first base paper 110 and the second base paper 120 are stacked vertically, the first slit 131 and the second slit 133 are offset from each other, so that the inner peripheral surface and the bottom surface of the seating portion 130 are formed when the seating portion 130 is recessed and formed.

[0050] Circular or radially polygonal first slit center holes 132 and second slit center holes 134 are cut at the respective center points of the first slit 131 and the second slit 133, and are configured to be expanded in the process of expanding the first slit 131 and the second slit 133 when the seating portion 130 is formed, so that ventilation holes are formed on the bottom surface of the seating portion 130.

[0051] A plurality of the seating portions 130 are arranged on the seat plate body 100, and are recessed and formed at a certain depth so as to have an inner shape corresponding to the outer shape of the product to be packaged.

[0052] The seating portion 130 is configured such that when the first slit 131 and the second slit 133 are radially expanded during the recessed forming in the paper seat plate forming step (S40), the upper surfaces of the first base paper 110 and the second base paper 120 alternately form the inner peripheral surface and the bottom surface of the seating portion 130.

[0053] As described above, the manufacturing method of the seat plate for product packaging according to the present invention and the seat plate manufactured thereby can more easily provide an environmentally friendly seat plate for product packaging using existing paper-made paper.

[0054] Therefore, compared with the conventional manufacturing technology of seat plates or egg seats using synthetic resins or foamed resins, the present invention can significantly reduce the economic burden associated with environmental pollution induction and waste treatment, and can also achieve the effect of carbon neutrality.

[0055] In particular, different from the conventional seat plate or egg seat manufacturing technology using pulp raw materials, the present invention can embody stable formability by applying the manufactured paper itself as a base paper to the mold used in the existing seat plate manufacturing, so that complex papermaking processes can be omitted to reduce production costs, and high-quality packaging seat plates made of more environmentally friendly paper raw materials can be manufactured, etc.
