Description

Method for manufacturing a container using seaweed or chaff and a container manufactured by the manufacturing method{Manufacturing Method of container using seaweed or chaff}

The present invention relates to a method for manufacturing a container using seaweed or rice husk and a container manufactured by the manufacturing method.

Here, background arts related to the present disclosure are provided, and these do not necessarily mean known technologies.

In addition to the development of the overall industrial economy, human life culture has been diversified and various types of disposable containers that can save time are being produced and used. Examples of such disposable containers include lunch boxes, plates, cups, and packaging containers for electronic products.

Most of these disposable containers are made of synthetic resin such as polystyrene or pulp. However, the product using the synthetic resin or the like contains not only a large amount of components harmful to the human body, but also has a problem in that it is not easy to dispose of the waste due to an increase in the amount of use, and thus there are certain restrictions on its use.

In addition, since most of the paper products using the pulp are manufactured using imported pulp, high cost is required from an economical point of view, and in order to produce pulp, not only the forest that is the raw material is necessarily destroyed, but also produced it Environmental pollution problems may be caused by additives or the like that are added to the process. Furthermore, even if recycled pulp is used instead of pulp, secondary environmental pollution problems caused by disposal of products after treatment and use of energy required for regeneration and additives used in various regeneration processes cannot be overlooked.

On the other hand, in order to solve the structural problem of the pulp material, containers whose surface is waterproofed with vinyl or the like are also used, but as a main cause of environmental pollution, there are restrictions on its use, and in establishments using such containers, etc. After use, the container must be collected separately.

As described above, when most of the conventional disposable containers are simply buried in the ground, the soil is contaminated because it does not naturally decompose, and also is naturally decomposed to solve the problem of discharging environmental pollutants such as dioxins during incineration. Disposable containers and the like are produced. However, this also has a problem in that its production cost is expensive due to the use of imported pulp, and there is a structural problem in that its shape is deformed due to some dissolution in water when it comes into contact with water. It is a situation in which polyethylene is coated on the surface, or the outer surface is spray-coated. However, the polyethylene is also not an eco-friendly material, and contamination may occur in the spray coating process, and it must be treated as waste after use, and there is a problem in practical mass production because it is produced through a complicated process.

The above effects and additional effects are described in detail below.

Before describing the present invention in detail below, it is understood that the terms used herein are only for describing specific embodiments and are not intended to limit the scope of the present invention, which is limited only by the scope of the appended claims. shall. All technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the art unless otherwise stated.

Throughout this specification and claims, unless otherwise stated, the terms comprise, comprises, comprising means referring to an article, step or group of articles, and steps, and any other article It is not meant to exclude a step or group of things or a group of steps.

On the other hand, various embodiments of the present invention can be combined with any other embodiments, unless otherwise indicated. Any feature indicated as particularly preferred or advantageous may be combined with any other feature or features indicated as preferred or advantageous. Hereinafter, embodiments and effects according to the present invention will be described with reference to the accompanying drawings.

A method for manufacturing a container using seaweed or rice husk and grain according to an embodiment of the present invention includes mixing dried seaweed or rice husk with rice flour, starch powder, and gluten, and water, and a shape maintaining agent contributing to container shape maintenance As, it comprises a step of adding salt, the step of kneading the mixture, the step of molding the dough into a container shape, drying the molded container and heat-treating using steam.

The type of the container is not limited, and may be, for example, a bowl or cup.

First, it is mixed with water, including dried seaweed or rice husk, rice flour, starch powder, and gluten. The type of rice is not limited, and may be glutinous rice, for example. The kneading step is 80 parts by weight to 98 parts by weight of the rice flour, 1 to 10 parts by weight of the starch powder, 1 to 10 parts by weight of gluten, and 20 to 100 parts by weight of water. The material must be mixed in the above range to provide excellent container durability and good container formability.

The seaweed is dried to prepare and use the dried seaweed. The type of seaweed is not limited. It can be selected from green algae, red algae, and brown algae, and includes seaweed, green onion, seaweed, kelp, seaweed, and 톳. Of these, kelp is preferred for container durability. Seaweed can increase the durability of the container, improve molding, and obtain the necessary mechanical properties. In particular, it is preferable to use the seaweed dried to 1 to 10% by weight of water content. Drying in the above range can improve the mechanical strength of the container.

The shape of the dried seaweed is also important. Taking kelp as an example, the shape of the dried kelp affects the mechanical strength and moldability of the container, and the appearance of the container. Preferably, the dried seaweed has an average width of 0.5 to 1 cm, and an average length of 4 to 7 cm. It is good to be mine. If it is less than the above range, the mechanical strength is poor, and if it is above the above range, the moldability is poor, and the container appearance may be rough.

In addition, the mixing step is preferably mixed so that the weight ratio of dry seaweed dried to 1 to 10% by weight of the total weight of the rice flour, starch powder, and gluten is 1 to 10% by weight. When the dry seaweed enters below the above range, the durability decreases, and when the dry seaweed enters above the range, the container outer structure is difficult to make, and the moldability is poor.

On the other hand, various additives may be used to improve the bonding strength of the materials and the shape of the container and to improve the durability of the container, but in one embodiment of the present invention, it is characterized by adding salt. By adding salt, it was confirmed that the shape retention and durability of the container were increased. The amount of salt added is preferably included in an amount of 0.1 to 5 parts by weight based on 100 weight of the total solids in the container. Below the above range, the durability of the container is deteriorated, and when it exceeds the above range, the effect of improving the properties is saturated, which is not preferable.

Next, after sufficiently kneading the mixture, it is molded into a container shape. The shape of the container is not limited, and may be a cup, a bowl, or the like. After the molding is completed, the molded container is first dried, and then heat-treated. The heat treatment method is also important, and heat treatment using steam can prevent cracks in the container. After the steam heat treatment, drying may be performed again.

Next, when used as a cup or container, it comes into contact with water, so surface treatment is performed to reduce the absorption rate of moisture. For an eco-friendly and bio-friendly surface treatment, in one embodiment of the present invention, at least one powder of buckwheat, acorn, mung bean is immersed in water and boiled to collect the boil, and then coated or dried on the inside or all of the prepared container. By going through this process, the absorption rate of water is reduced, so that the shape of the container can be maintained for a long time and strength can be maintained.

Hereinafter, the present invention will be described in more detail through examples and comparative examples. The following examples are intended to illustrate the invention, and the scope of the invention is not limited by these examples.
