Description

Container using plant leaves and its manufacturing method {CONTAINER USING PLANT LEAF AND MANUFACTURING METHOD THE SAME}

The present invention relates to a container using plant leaves and a manufacturing method thereof.

As the industry develops, disposable containers are rapidly produced, and these disposable containers have emerged as essential items when going out in the outdoors as well as in general homes.

Most of the disposable devices on the market are made of synthetic resin. Although the use of these disposable devices is increasing day by day, most of these disposable devices are made of synthetic resins and take hundreds of years or more to decompose, which is a situation that has a great adverse effect on the environment. In addition, even when incinerated, there are problems such as polluting the atmosphere by generating a large amount of soot.

On the other hand, since environmental pollution is becoming serious due to the increase in the amount of synthetic resin, materials that replace synthetic resin are being developed. Although biodegradable synthetic resins have been developed, these are also micro synthetic resins that remain in soil or water when decomposed and can pose a threat to life if ingested. Therefore, since synthetic resin containers have a number of problems, a fundamental solution to solve them is required.

Accordingly, a method for manufacturing a container using a wood-based raw material is disclosed in Patent Document 1, Korean Laid-Open Patent No. 10-2016-0066613. Korean Patent Laid-open Publication No. 10-2016-0066613 relates to a container made using fallen leaves and a manufacturing method. The fallen leaves are crushed, the crushed leaves and paper are mixed to produce fallen leaves, and then the fallen leaves and pulp are combined to form a container. A manufacturing method is disclosed. In this way, when wood-based raw materials such as fallen leaves are used, there is a problem in that the processing process is complicated and the manufacturing cost increases due to pretreatment and processing of the wood-based raw materials.

Plant leaves used in the manufacture of containers using plant leaves according to an embodiment of the present invention have the following characteristics. Plant leaves are composed of a leaf body, leaf veins, and petioles. That is, plant leaves include both a leaf body and a petiole called a leaf blade. The leaf body is an important part of the leaf and has a flat shape to easily receive sunlight. Leaf veins are connected to the vascular bundles of the stem as passages for nutrients or water. Leaf veins are divided into veins along with net veins according to the spreading shape. 9 is a diagram for explaining the structure of the petiole, the petiole is the apex part attached to the stem and supporting the leaf body, and serves as a passage for moisture and nutrients between the leaf body and the stem and turns the leaf in the direction of sunlight. The petiole is thicker than the leaf body, and strong longitudinal fibers are developed to serve as a support. The cuticle layer of plant leaves forms the outer surface. Plant epidermis is covered with the cuticle, which is a lipid polymer layer impregnated with wax present on the outer surface. Since the cuticle is composed of an insoluble cuticular membrane and does not pass water, a container made of plant leaves without a separate coating has the advantage of not being damaged even if it receives moisture. It is preferable to use Sal tree Leaf as the plant leaf applied to the present invention, and it is preferable to use Areca palm as the petiole.
