[0006] However, when using natural materials such as bamboo bark or cattail, a process is required to shape the material into a container, for example by twisting the material into a thread or rope, and a process is required to weave the formed thread or rope. Because this is done manually, the time and cost required for manufacturing inevitably increases.

[0007] On the other hand, baskets made of polypropylene (PP) are known (see Non-Patent Document 2), but because PP baskets are woven mechanically, it is difficult to achieve the warmth and texture that are unique to natural materials.

[0008] The present invention was devised under these circumstances, and its purpose is to provide a natural material-like container that can exhibit the warmth and texture of natural materials while significantly reducing the time and cost required for production. [Means for solving the problem]

[0009] In order to solve the above-mentioned problems, the natural material container of the present invention comprises a rope-like member made of twisted tapes made of synthetic resin, and a thread-like member that connects adjacent rope-like members together, and at least the side wall of the container is formed by the rope-like members being wound in a spiral shape and connected together by the thread-like members. Effect of the Invention

[0010] The natural material-like container of the present invention can provide the warmth and texture of natural materials while significantly reducing manufacturing time and costs. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the embodiment of the present invention will be described with reference to the drawings. Note that the drawings are schematic or conceptual, and the dimensions of each component, the size ratio between components, etc. are not necessarily the same as those in reality, and even when the same components are shown, the dimensions and ratios between components may be different depending on the drawing. In addition, in the drawings attached to this specification, the shape, scale, vertical and horizontal dimensional ratio, etc. of each part may be changed or exaggerated from the actual ones in order to make it easier to understand.

[0013] [Overall configuration of the natural material container according to this embodiment] FIG. 1 is a schematic perspective view of a natural material-based container according to an embodiment of the present disclosure. The natural material-based container 1 according to this embodiment includes a main body 10 and a handle 20. R (20 L The main body 10 is made up of a rope-like member 11 and a thread-like member 12 (see FIG. 1). The rope-like member 11 is made of a tape 11 made of synthetic resin. T The natural material-like container 1 can be formed by twisting the rope-like members 11 together. The thread-like members 12 are used to connect adjacent rope-like members 11 (in this embodiment, they are mainly stacked one on top of the other). In the natural material-like container 1 of this embodiment, the main body 10 can be formed by winding the rope-like members 11 in a spiral shape and connecting them with the thread-like members 12. Note that a handle is not a required component of the present invention, but having a handle makes the natural material-like container 1 easier to carry.

[0014] The natural material container 1 includes a main body 10 and a handle 20. R (20 L ) is mainly made of synthetic resin. In particular, polyethylene (PE) is preferably used as the material for the natural material-like container 1 in this embodiment, as it is easy to process and has excellent lightness. The material of the rope-like member that constitutes the main body of the natural material-like container according to the present invention is not limited to polyethylene, and may be, for example, polypropylene (PP).

[0015] [Regarding the rope-like member constituting the natural material-based container according to this embodiment] 2(A) is a schematic diagram for simply explaining a method for forming a rope-like member constituting the natural material-like container according to the present embodiment. The rope-like member 11 is a PE tape 11 formed from, for example, polyethylene (PE) pellets as a synthetic resin. T The PE tape 11 can be twisted in the direction of the arrow to form a shape. T When the PE tape 11 is shaped as a sheet, multiple thin, stripe-like lines parallel to the longitudinal direction can be formed on at least one side of the sheet. The appearance of the rope-like member 11 formed by twisting the PE tape 11 as described above so that the side on which the lines are formed becomes the surface looks like the outer skin of a cattail. This allows the natural material-style container 1 according to this embodiment to have the warmth and texture of natural materials. In addition, the PE tape 11 T It is preferable that the tape is not transparent but is colored, for example, straw-colored, to closely resemble the color of the natural cattail.

[0016] FIG. 2(B) is a schematic diagram showing the state in which the rope-like members constituting the natural material-based container according to this embodiment are connected by a thread-like member, and is the same as the reference numeral 10 in FIG. EX 1 is an enlarged view of a portion of the container 1 according to the present embodiment. As described later, the natural material-like container 1 according to the present embodiment is made by winding a rope-like member 11 in a spiral shape and connecting the rope-like member 11 with a thread-like member 12. A sewing machine can be preferably used as a method of connecting the rope-like member 11 and the thread-like member 12. This significantly improves work efficiency, unlike conventional containers made of natural materials, which are made by manually weaving rope-like members made of natural materials such as cattails or by using an adhesive that is difficult to work with and not very strong. In addition, the strength and durability of the completed natural material-like container 1 are significantly improved compared to conventional containers made of natural materials. Furthermore, by being made of synthetic resin such as PE, the weight of the completed natural material-like container 1 can be significantly reduced. The material for the thread-like member 12 may be not only fiber (cotton, hemp, etc.) but also synthetic fibers such as nylon and polyester.

[0017] [Regarding the molding process of the natural material-based container according to this embodiment] 3 is a flow chart for explaining the molding process of the natural material-like container according to the embodiment of the present disclosure. Extrusion molding can be suitably used for molding the tape made of PE (synthetic resin) that constitutes the rope-like member 11 constituting the natural material-like container 1 according to the present embodiment. Below, the molding process of the rope-like member 11 (S1 to S6) and the molding process of the natural material-like container 1 (S7 to S9) will be explained separately.

[0018] [About the forming process of rope-like components] The molding process of the rope-like member 11 constituting the natural material-derived container 1 according to this embodiment will be described with reference to steps S1 to S6 in Fig. 3. Since a known extrusion molding machine (not shown) is used in the extrusion molding, the following description will focus on the parts related to the molding of the natural material-derived container 1 according to this embodiment, and will briefly explain the conventional steps.

[0019] First, a pellet-shaped polyethylene (PE) resin in an amount sufficient to mold a PE tape of a desired length is charged into a hopper of an extruder (step S1). T As described above, the PE resin needs to be colored straw-colored. There are internal and external coloring for coloring PE, and internal coloring is preferably used for molding the rope-like member 11 here. Among them, it is preferable to use a master batch or colored pellets, taking into consideration ease of processing and ease of reproducing the desired color when coloring. When coloring with a master batch or colored pellets, they are added at the desired timing when the PE resin pellets are fed into the hopper of the extruder in step S1.

[0020] Next, the desired PE tape 11 is extruded. T The PE tape 11 is molded (step S2). T A mold capable of obtaining the size (thickness: 0.5 mm to 5 mm, width: 5 mm to 50 mm) of the PE tape 11 can be used. TAs described above, multiple thin stripes must be formed on at least one side of the tape. T It is necessary to use a mold having a formable pattern engraved on at least one side of the mold.

[0021] Next, the PE tape after molding 11 T The cooled PE tape 11 is cooled in a cooler (step S3). T (Step S4), and the PE tape 11 after being taken out T The PE tape 11 is cut to a desired length (step S5). The length to be cut in this case may be a length required for forming one natural material-based container 1. Note that, for forming one natural material-based container 1, one PE tape 11 is used. T Even if you use more than two PE tapes 11 T The diameter of the rope-like member 11 to be described later may be used as the PE tape 11 to be used. T When a rope-like member 11 with a large diameter is required, three or more PE tapes 11 are used. T For example, when forming a rope-like member 11 having a diameter of 10 mm or more, it is preferable to use three or more PE tapes 11. T It is preferred to use:

[0022] Then cut the PE tape to the desired length. T The rope-like member 11 can be formed by twisting the strands of the fibers together using a machine (not shown) capable of twisting (step S6).

[0023] [About the molding process for natural material-based containers] Next, the molding process of the natural material-like container 1 will be described. First, the rope-like member 11 formed in step 6 is wound in a spiral shape to form the main body 10 (step S7). More specifically, if the main body 10 is made up of only side walls that do not include a bottom surface, the rope-like member 11 is wound around to draw a desired circle, and when the circle (the circle at the bottom) is completed (the starting point and end point of the circle), the rope-like member 11 is wound around again to draw the next circle and is layered on the circle at the bottom. Then, at the same time as the next rope-like member 11 is layered on the rope-like member 11 located at the lower layer, or following this, the adjacent rope-like members 11 are sewn together using the thread-like member 12 with a sewing machine. This is repeated until the side walls of the main body 10 of the desired size (height) are formed.

[0024] On the other hand, if the main body 10 includes a bottom surface, the inside of the lowest circle must form the bottom surface, so the rope-like member 11 is wound in a coil shape starting from the center of the circle, and after the bottom surface portion is formed, the rope-like member 11 is wound in a spiral shape as described above. In this case, too, the adjacent rope-like members 11 are sewn together using the thread-like member 12 with a sewing machine, either simultaneously with or following the winding of the rope-like member 11.

[0025] Next, the handle portion 20, which has been formed in a substantially U-shape in advance, is R and handle 20 L are attached to the main body 10 so as to be arranged opposite to each other (step S8). In this embodiment, as shown in FIG. 1, the handle portion 20 is arranged from the bottom to the top of the main body 10. R and handle 20 L However, the present invention is not limited to this. Even if the main body 10 has a configuration in which a part of the main body 10 extends from the middle to the top, the handle portion 20 may be provided near the top. R and handle 20 L However, the handle portion 20 of this embodiment may be configured to be attached. R and handle 20 LIf the attachment to the main body 10 is made in this manner, it is expected that the strength of the completed natural material-based container 1 will be increased.

[0026] The natural material container 1 of this embodiment can be completed through the above steps, and according to the above-mentioned molding process in this embodiment, the manufacturing time can be reduced to 1 / 5 for a container of the same size, compared to the manufacturing time required for a PP container traditionally produced by hand weaving.

[0027] The above-described embodiments are described for the purpose of facilitating understanding of the present invention, and are not described for the purpose of limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design modifications and equivalents that fall within the technical scope of the present invention.

[0028] In the present embodiment, the natural material-like container 1 is a container with a generally cylindrical shape and a slightly elongated (deep) structure in which the outer circumference becomes larger toward the top, but the present invention is not limited to this, and can also be applied to containers with slightly shallow depths, such as ellipses, whose length and width differ in plan view. In addition, the present invention is not limited to containers, and the method for manufacturing the natural material-like container of the present invention can be applied to molding flat items such as rug mats. Specifically, the structure of the natural material-like container of the present invention can be applied to, for example, pet beds, ornaments, baskets for interior storage, storage for kitchen utensils, and potted plant covers.

[0029] Furthermore, the natural material container according to the present invention is basically made of synthetic resin, so it can be used both indoors and outdoors. For example, while containers made of normal natural materials are difficult to use in humid places or outdoors, the natural material container according to the present invention can be used in places around water such as bathrooms and kitchens, and even outdoors.

[0030] Furthermore, it can be washed with water (fully washed) and has antibacterial and antifungal properties, making it hygienic, durable, and usable for a long time, while also helping to reduce the burden on the environment. [Explanation of symbols]
