AI Technical Summary

Technical Problem

Existing disposable trash containers, such as those made of nylon or polyethylene, tend to bounce back and reopen when rolled up, making it difficult to maintain a tidy table environment, especially in settings like conveyor belt sushi restaurants where customers are expected to clean up their own waste.

Method used

The trash container is designed with a bounce prevention mechanism inspired by origami, featuring a holding blade resembling an upside-down flower petal or a film cover with a central cut, ensuring the container remains closed.

Abstract

To provide a simple disposable trash bin that is convenient for cleanup.SOLUTION: The most cost-effective method is to first connect the sides, fit them into the mold, and press them with the top mold to fold them in. Another method is to attach a flap to an existing paper cup, add a cross-shaped perforation to its center, and fold the perforation inward when in use.SELECTED DRAWING: Figure 5

Description

[Technical Field]

[0001] To prevent the box from bouncing back, fold the top of the box over and fold Figures 1 and 2 as shown in Figure 3. This creates a gap in the center that makes it easy to put garbage in from the outside, but difficult to put in from the inside. This also has the same effect as putting a lid on a paper cup, as shown in Figure 5, with a perforation such as a cross so that it can be opened when in use. [Background technology]

[0002] Origami-style foldable small box [Patent documents]

[0003] [Patent Document 2] Patent Publication No. 09-040102 Summary of the Invention [Problem to be solved by the invention] When eating out, temporarily store table trash in a small trash box to keep the table tidy and make it easier to eat and more aesthetically pleasing. In particular, try to seal up chopstick holders and simple hand towel wrappers made of nylon or polyethylene, which tend to bounce back and open no matter how many times they are rolled up and placed. [Means for solving the problem] The entrance to the small garbage bin is fitted with a bounce prevention function in the same way as origami, by attaching a holding blade resembling an upside-down flower petal, or by covering the mouth of the container with a film cut in the center and weaving it inside, thereby preventing garbage from bouncing back. [Effects of the Invention] It is firmly held down as shown in the photo in Figure 4. The left shows the item before it was wrapped in nylon or polyethylene, which keeps opening up no matter how many times you roll it up, and the right shows the item after it was wrapped up. [Brief explanation of the drawings] [Figure 1] A simple disposable trash can made from A4-sized paper. The weak spot is where the horizontal joint overlaps with one of the blades. [Figure 2]The weak point in Figure 1 has been fixed by connecting one of the side faces in the center. [Figure 3] The finished version in Figure 1 and its folded state. It is foldable and can be reused. [Figure 4] On the left is the small box with trash before use, and on the right is the box with trash inside. No bounce occurs. [Figure 5] A paper cup with a lid and a cut in the center to prevent splashing [Industrial Applicability] In the restaurant industry, especially conveyor belt sushi restaurants, tables are kept neat and tidy. In addition, customers are required to clean up table waste themselves, which saves time and increases customer turnover.

Claims

1. Chopstick holders and simple hand towel wrappers made of nylon, polyethylene, etc. tend to bounce around and fly out of small trash cans, making them difficult to fit into. These are sealed from above with blades resembling upside-down flower petals. This makes it easier for trash to fit into the trash can, but once inside, it is difficult for trash to fly out. This bounce-prevention function is claimed. The same effect can be obtained by attaching a lid to a paper cup and perforating it with a cross or other perforation so that it opens when in use, instead of using a holding blade.

2. When eating out, chopstick holders and towel wrappers are scattered all over the table, which looks unsightly and makes it difficult to eat. Nylon and polyethylene trash cans, in particular, stretch easily when bent, making them a nuisance. Therefore, we created a simple, disposable trash box that neatly stores the trash generated while eating and can be disposed of directly in the large trash can in the kitchen, making it convenient for tidying up.
