Description

Lotus seedpod eco-friendly chopsticks This invention relates to a lotus seedpod-based eco-friendly chopsticks, which is a type of tableware. Lotus pods are one of the main waste products of the lotus industry. Currently, the main ways to reuse them are to boil them into reddish-brown dye or to make them into decorative handicrafts. However, apart from dyes and handicrafts, there are currently no other ways to reuse lotus pods, so the waste rate of lotus pods still needs to be improved. In view of the above-mentioned shortcomings and drawbacks, the inventor believed that it was necessary to make corrections. Therefore, based on years of experience in related technologies and product design and manufacturing, and adhering to the concept of excellent design, the inventor researched and created the Lotus Seedpod Eco-friendly Chopsticks. After continuous efforts, the inventor finally launched the Lotus Seedpod Eco-friendly Chopsticks, aiming to correct the product structure and improve the product's excellent effects. The main purpose of this invention, the lotus seedpod eco-friendly chopsticks, is to provide tableware made from lotus seedpods. To achieve the aforementioned purpose, the lotus seedpod eco-friendly chopsticks of this invention are made through the following steps: First, the lotus pods are dried with hot air. Then, the dried lotus pods are crushed and ground into powder using a grinder. The lotus pod powder is then mixed with bamboo fiber and natural resin. The mixture is then hot-pressed to complete the process. Compared to previous methods of recycling lotus pods, which were only used to make dyes and handicrafts, this invention opens up a new way to reuse discarded lotus pods. This can effectively reduce the waste rate of lotus pods, and the raw materials of the eco-friendly chopsticks are all natural, thus further enhancing their environmental friendliness and making them extremely friendly to the ecological environment. In addition, the lotus pods, combined with other natural raw materials, are lightweight, biodegradable, harmless to the human body, and recyclable. It is clear that this invention is a highly practical and progressive product. This invention relates to a lotus seedpod-based eco-friendly chopsticks, which are made by the following steps: First, the lotus pods are dried with hot air at 80℃ for 30 hours. Then, the dried lotus pods are crushed and ground into powder using a grinder, and the powder with a particle size of 80-120 mesh is sieved. Next, the lotus pod powder, bamboo fiber, and shellac flakes are weighed as raw materials, with the proportions of lotus pod powder, bamboo fiber, and shellac flakes in the total weight of the three raw materials being 20-80%, 20-80%, and 0.1-0.5%, respectively. Then, the shellac flakes are dissolved in 95% ethanol to become shellac lacquer. The weight ratio of shellac flakes to 95% ethanol during dissolution is 3:7. The shellac lacquer, lotus pod powder, and bamboo fiber are then mixed and stirred evenly. The mixture is then placed into a pre-designed chopstick-shaped mold and hot-pressed at a temperature of 120-190℃, a pressure of 200-300 torr, and a time of 8-15 minutes to complete the process. The above description is merely one preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims should still fall within the scope of this invention. In conclusion, it is understood that the present invention is novel and inventive, and since the present invention has not been published in any publication, it complies with the provisions of Article 22 of the Patent Law. none none none
