Description
[Technical field]
[0001] The present invention relates to a fiber material paper-plastic disc-shaped product and a manufacturing method thereof, in particular to a paper-plastic disc-shaped product manufactured by dry hot pressing, which has many excellent characteristics such as being recyclable, naturally decomposable, light in weight, and able to withstand considerable loads. [Background technology]
[0002] The so-called "tray-type product" refers to a product with a large side inclination angle, a small depth (shallow), and the bottom can form a serving table for holding food or items, such as shallow dishes, shallow plates, dinner plates, buffet plates, fruit platters, food platters, etc. Early tray-type products were made of metal and carved out of wood. Later, molds were developed to inject resin materials into tray-type products, which are generally called plastic tray-type products.
[0003] "Plastic products" made of resin materials (including plastic disc-shaped products) have been used for a long time because of their fast manufacturing speed and the ability to spread and reduce costs. In recent years, studies have found that plastic products made of resin materials are prone to releasing toxins that seriously pollute the environment, are difficult to recycle and reuse after destruction, or are difficult to dispose of after recycling and decomposition, and have huge recycling and processing costs. These industrial pollution problems have caused serious damage to global environmental protection over the years, so disc-shaped products made of resin materials have also been criticized.
[0004] In response to environmental protection trends and the requirement to reduce the use of plastics, and in the drive to find new materials, a manufacturing technology has been developed that uses pulp fiber materials and / or mixed pulp containing plant fiber materials as pulp materials, uses a pulp suction mold to absorb the pulp and attaches the pulp, and then undergoes hot pressing to shape the finished product. This technology is generally referred to as the "paper plastic product manufacturing method". The finished products made by this manufacturing method are generally called "paper plastic products" to make a clear distinction from "plastic products".
[0005] Paper plastic products have the advantage of being easy to recycle, remanufacture and reuse, which conforms to the trend of environmental protection, reuse and energy saving and carbon reduction. Therefore, they are quickly accepted by the industrial and commercial sectors and the public and are willing to adopt them. Paper plastic products are often seen in products such as bowls, deep bowls, cup lids, packaging materials, shock-absorbing materials, cushioning materials, etc. Paper plastic products have been gradually adopted in the manufacturing methods and process techniques of paper plastic products in recent years. There have been many improvements and changes, but using fiber materials as the starting material is its basic principle.
[0006] Even though the manufacturing technology of paper plastic products has been developed, there is still no paper plastic tray product with good use effect. The reason is that the finished product of "tray product" is mainly used to hold food or goods, so it must have the characteristic of bearing a considerable load. If it cannot bear a considerable load, the surface may break when carrying food or goods, or even break the goods. That is, because the tray products manufactured by the general paper plastic product manufacturing method cannot meet the requirement of bearing a considerable load, there is no paper plastic tray product with good use effect. [Summary of the invention]
[0007] The purpose of the present invention is to provide a fiber-made paper-plastic disc-shaped product having many excellent properties such as being recyclable, decomposable, light in weight, and able to withstand considerable loads, and a manufacturing method thereof.
[0008] To achieve the above-mentioned purpose, the present invention provides a fiber material paper-plastic plate-shaped product, which has a serving table, which is surrounded by a slight bend on all sides, and the outer side of the slight bend rises to form a short and shallow rising slope. The rising slopes on all sides are integrally connected to a curved slope, and the common top edge of the rising slope and the curved slope is formed into a groove; the groove extends outward to form an upward concave arc-shaped side wall, and at least one horizontal groove is formed on the arc surface of the arc-shaped side wall. A lace decorative wall is integrally connected between two adjacent arc-shaped side walls, which is formed by a plurality of small wall bodies protruding upward with a concave decorative groove, and the lace decorative wall is integrally formed with the arc-shaped side wall adjacent to the side, and the bottom edge of the lace decorative wall touches the groove of the rising slope and the top edge of the curved slope.
[0009] In the above-mentioned fiber material paper-plastic disc-shaped product, the lace decorative wall is formed into a plurality of small wall bodies in the shape of upwardly protruding petals.
[0010] In the above-mentioned fiber material paper-plastic disc-shaped product, the plurality of small wall bodies in the shape of upwardly protruding petals are arranged in an inwardly curved arc shape.
[0011] The present invention also provides a method for manufacturing a fiber-based paper-plastic disc-shaped product, which uses a mixture of pulp fiber material and / or plant fiber material as raw materials, and solidifies the raw material into a flat pulp board through molding as a starting material, and undergoes the following manufacturing steps:
[0012] (1) The thin sheet of pulp is conveyed through a cutting machine, and a plurality of raw materials are cut out simultaneously on the pulp;
[0013] (2) The majority of the raw materials are transported and coated with a solution containing additives;
[0014] (3) The coated raw material is conveyed to a hot pressing molding machine, which heats and presses the raw material. The hot pressing molding machine is equipped with a molding die corresponding to the paper-plastic disc-shaped product before completion. Therefore, during the process of heating and pressurizing the raw material, each raw material is pressed by the molding die, thereby forming a paper-plastic disc-shaped product with an appearance similar to that of the paper-plastic disc-shaped product;
[0015] (4) Send the paper-plastic disc-shaped products to a trimming machine, and perform trimming on the overflow of each type of paper-plastic disc-shaped products, so that the original paper-plastic disc-shaped products are transformed into the paper-plastic disc-shaped products.
[0016] In the above-mentioned method for manufacturing fiber-material paper-plastic disc-shaped products, after the primary blank is transported and coated with a solution containing an additive, it can be selected whether to be sent to a place for standing. The standing is selected so that the solution received by each primary blank can penetrate evenly into the interior, so as to achieve the effect of the primary blank being infiltrated by the solution in a balanced manner.
[0017] The advantages and beneficial effects of the present invention are:
[0018] 1. The present invention adopts a specific manufacturing method to manufacture the paper-plastic disc-shaped product, and the paper-plastic disc-shaped product itself also has a specific structure. Therefore, the present invention is novel and creative in both the finished product and the manufacturing method of the paper-plastic disc-shaped product.
[0019] 2. The paper-plastic tray product of the present invention has the characteristic of being able to withstand considerable loads, and the serving table is more convenient for holding food or articles, and can fully achieve the intended use effect of the tray product.
[0020] 3. The paper-plastic disc-shaped product of the present invention uses a thin sheet of pulp board as the starting material and is manufactured and formed by a specific manufacturing method. The pulp board is a mixture of pulp fiber material and / or plant fiber material as the original raw material. Therefore, the paper-plastic disc-shaped product of the present invention has many excellent characteristics in use, such as being recyclable, naturally decomposable, light in weight, and able to withstand considerable loads.

[0029] The present invention is divided into a "fiber material paper-plastic disc-shaped product" and a "method for manufacturing a fiber material paper-plastic disc-shaped product", which are described in sequence as follows.
[0030] The fiber-material paper-plastic plate product protected by the present invention has the following structure: Figures 1 to 4 As shown, the paper-plastic plate-shaped product 1 has a lowest-positioned holding platform 10 for holding food or articles, and is surrounded by a slight bend 11 to enhance strength, and then slightly rises from the outer side of the slight bend 11 to form a short and shallow rising slope 20, and the rising slopes 20 on the four sides are integrally connected with a curved slope 21, and the common top edge of the rising slope 20 and the curved slope 21 is formed into a groove 22, which has the effect of enhancing beauty and strength, and extends outward from the groove 22 to form an upwardly concave arc-shaped side wall 30, which is an arc-shaped side wall extending upwardly in an arc shape, and at least one transverse groove 31 is formed on the arc surface of the arc-shaped side wall 30, and the groove 31 is shown in the figure of the present invention. There are two, but not limited to three or more grooves 31 to enhance the aesthetics and strength of the arcuate side wall 30. The projection of the arcuate side wall 30 is roughly square, so a lace wall 40 is integrally connected between two adjacent arcuate side walls 30. It is formed by a plurality of small wall bodies in the shape of petals protruding upwards with a concave groove 41, and is integrally formed with the adjacent arcuate side walls 30. The plurality of small wall bodies in the shape of petals protruding upwards on the lace wall 40 are preferably arranged in an inwardly curved arc shape, so that it can be connected with the adjacent arcuate side walls 30 without any chiseling marks. The connection between the lace wall 40 and the arcuate side walls 30 is not abrupt, and the bottom edge of the lace wall 40 just touches the groove 22.
[0031] The fiber-material paper-plastic tray product 1 protected by the present invention, wherein the container 10 has a considerable area, and because it is molded from fiber material, it can have an appropriate thickness to make it quite strong and can be used to hold food or articles (such as Figure 3As shown in FIG. 1 ); the micro-bend 11 and the groove 22 both have the effect of assisting the container 10 in enhancing the strength of the surrounding content; the rising slope 20 has the effect of guiding the arc-shaped side wall 30 to rise, and the curved slope 21 has the effect of guiding the lace decorative wall 40 to rise, so that the overall surrounding rising state has no sense of incongruity; the at least one horizontal groove 31 can enhance the aesthetics and strength of the arc-shaped side wall 30. The plurality of small wall bodies in the shape of raised petals are formed by a concave decorative groove 41. In addition to enhancing the aesthetics of the lace decorative wall 40, it mainly creates a lace decorative wall 40 with excellent strength, and can achieve the effect of strongly supporting the paper-plastic disc-type product 1 at several key turning points of the paper-plastic disc-type product 1 (as shown in FIG. 1 ). Figure 4 As shown in the figure, the overall paper-plastic tray-shaped product 1 not only has a beautiful appearance, but also has strong and strong characteristics hidden in the beauty, which is enough to achieve the function of the paper-plastic tray-shaped product 1 to hold food or articles.
[0032] The present invention also protects a "method for manufacturing fiber-material paper-plastic tray-shaped products". In the structure of the present invention, the holding platform 10 has a considerable area, so the present invention uses "pulp board" as the starting material. The "pulp board" referred to herein refers to a pulp fiber material and / or plant fiber material that is beaten and mixed as the original pulp-like raw material, and is molded and solidified into a flat-plate pulp board with a certain area and thickness (adjustable) for easy storage and transportation. When solidifying into a pulp board, its length, width and height can be selected. Because the pulp board is a starting material that will be used for further processing and manufacturing, the molding makes it possible to form a thin flat-plate pulp board with extremely low humidity even if it is not completely dry after solidification, so as to be used as the starting material for further manufacturing.
[0033] Before manufacturing the paper-plastic disc product 1, the present invention must first prepare a "pulp board" as a starting material, and then go through the following manufacturing steps:
[0034] 1. The thin sheet of pulp is conveyed through a cutting machine. The cutting machine increases the size of the paper-plastic disc-shaped product 1 to be pressed and trimmed according to the length and width of the paper-plastic disc-shaped product 1. A plurality of raw materials to be finally manufactured into the paper-plastic disc-shaped product 1 can be cut out on the same pulp board at the same time. The adjacent spaces of the plurality of raw materials on the same pulp board can be disconnected or connected. The "---disconnected---" referred to here means that the adjacent spaces of the raw materials have been cut by the cutting machine, but the plurality of raw materials on the same pulp board are still assembled within a certain range; the "---connected---" referred to here means that the adjacent spaces of the raw materials are still connected with the minimum contact, and the rest are all cut off by the cutting machine;
[0035] 2. Next, the plurality of raw materials are conveyed and coated with a solution containing an additive. The term "coating" herein refers to spraying, brushing or dipping the solution containing the additive so that the solution containing the additive adheres to the surface of the plurality of raw materials. Any coating operation may be performed manually or mechanically. The surface of the raw materials is coated with the solution containing the additive, which is the most basic function of sealing the surface of the raw materials and at least having a waterproof and oil-proof effect. In addition to coating the top surface of the raw materials, the bottom surface of the raw materials may also be coated if necessary.
[0036] 3. Next, the raw materials that have passed the coating operation are sent to a place for static placement. If static placement is selected, in order to allow the solution received by each raw material to evenly penetrate into the interior and achieve the effect of the solution penetration balance of the raw material, whether the raw material is static and the static placement time are determined according to the size and thickness of the object. If static placement is not selected, the raw materials that have passed the coating operation can directly proceed to the next step;
[0037] 4. Then, the blank material that does not need to be left still or has been left still is transported to a hot press molding machine, which directly heats and pressurizes the blank material. The hot press molding machine is equipped with a molding die corresponding to the paper-plastic disc-shaped product 1. Therefore, in the process of heating and pressurizing the blank material by the hot press molding machine, each original planar blank material is hot-pressed and pressed by the molding die, thereby forming a "paper-plastic disc-shaped product" with an appearance similar to the paper-plastic disc-shaped product 1 to be manufactured. After each blank material is hot-pressed and pressed by the molding die, the micro-bend 11, the rising slope 20, the curved slope 21, the groove mark 22, the curved side wall 30, the groove mark 31, the lace decorative wall 40 and the concave decorative groove 41 of the paper-plastic disc-shaped product 1 are all formed and revealed. However, the "paper-plastic disc-shaped product" pressed and formed by the hot press molding machine will have some overflow around it, which is an inevitable phenomenon in the manufacturing process;
[0038] 5. Then, the "paper-plastic disc-shaped product" is sent to a trimming machine, and the overflow of each "paper-plastic disc-shaped product" is trimmed (of course, the original "---connection---" is disconnected at the same time), and the overflow is cut off according to the outer diameter or length and width of the paper-plastic disc-shaped product 1 to be manufactured, so that the original "paper-plastic disc-shaped product" becomes an independent paper-plastic disc-shaped product 1.
[0039] The present invention uses a thin sheet of pulp board as the starting material, and after the manufacturing steps of cutting, coating, standing, hot pressing and trimming, a paper-plastic disc-type product 1 is completed. Because the raw material is a mixture of pulp fiber material and / or plant fiber material, it is called a "paper-plastic disc-type product" to make a clear distinction from a "plastic disc-type product".
