AI Technical Summary

Technical Problem

Existing nets fail to effectively prevent crows from scattering garbage at shared disposal sites, and there is a need for a solution that can be easily distinguished by humans and prevent crow access to waste.

Method used

A dual-layer net with differently colored and lengthed sections, where the shorter net faces away from the garbage and the longer net faces the entrance, anchored to prevent crow access.

Benefits of technology

The dual-layer net structure effectively prevents crows from accessing garbage by using their weight to lift the longer net, while being easily distinguishable and portable for disposal.

Abstract

Provides a protective net to prevent crows from scattering garbage discarded at a garbage dump. [Solution] A double-layered net is created by overlapping a short net 1 and a long net 2 and connecting them at the upper end. The upper end of the double-layered net is installed at a high position in the garbage area, with the long net 2 facing the garbage side and the short net 1 facing the side where crows enter the garbage area, and the lower end of the long net 2 is extended further towards the side where crows 8 enter than the short net 1. Even if a crow 8 approaches the garbage 7 to make contact and lifts the short net 1, it cannot make contact with the garbage 7 because of the long net 2. Furthermore, since the crow 8 itself is stepping on the long net 2, it becomes difficult for it to lift the long net 2, thus preventing the crow 8 from making contact with the garbage 7.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Garbage disposal occurs daily, and since a garbage disposal site is shared by multiple households and multiple garbage bags are discarded, it is easy to dispose of garbage, and it is possible to take measures against crows scattering garbage on multiple garbage bags.

Means for Solving the Problems

[0005] The net of the present invention has a structure of two layers with different lengths and colors, where the upper ends are aligned so that the lower ends have different lengths. The shorter net faces away from the garbage, and the longer net faces the garbage side. The upper end of the net is attached to a higher part of the garbage disposal site so that the shorter net touches the ground. The lower end of the longer net is stretched to the side where crows can enter more easily than the shorter net.

Effects of the Invention

[0006] In a garbage disposal site where the net of the present invention is installed, since crows come into contact with the garbage, the shorter net on the side farther from the garbage is covered. ruSometimes, by stepping on the long net, the crow's own weight makes it difficult for it to lift the net, thus preventing the crow from coming into contact with the garbage.

[0007] In this invention, by changing the color of the short net 1 and the long net 2, humans can distinguish between the long net 2 and the short net 1, and by rolling up only the long net 2, they can easily dispose of the garbage in the garbage dump.

[0008] The net of this invention can be attached to the top of the entrance 6 of a pop-up tent 4 to create a portable trash disposal area. When transporting it, the net portion can be folded inside the tent 4 for easy carrying. [Brief explanation of the drawing]

[0010] Figures 2 and 3 show an embodiment of the net according to the present invention. The net is attached to the top of the entrance 6 of a pop-up tent 4, with the upper end 3 of the present invention serving as a garbage disposal area. When a person takes out garbage 7, they can easily place the garbage inside the tent 4 by lifting the long net 2 at the lower end. When a crow 8 approaches the garbage 7, it encounters the short net 1, and when it lifts it up, the long net 2 is in front of it, preventing it from reaching the garbage 7. Also, because the crow 8 is stepping on the long net 2 at that time, it is difficult for the crow 8 to continue lifting the long net 2, thus preventing the crow 8 from coming into contact with the garbage 7.

Claims

1. This net is designed primarily to prevent crows from rummaging through and scattering food waste. It consists of two nets of different lengths and colors, with their top ends tied together, creating a double-layered structure with varying lengths from bottom to top. The top end of the net is fixed high up in the garbage area so that the shorter net is just above the ground. The longer net faces the garbage side, and the shorter net faces the side where crows are likely to enter. Furthermore, the bottom end of the longer net is positioned to extend further towards the crow-intrusion side than the shorter net. This design makes it difficult for crows to lift the shorter net, as they can land on top of the longer net, thus preventing them from doing so.

2. A portable garbage disposal area comprising connecting the upper part of the garbage scattering damage prevention net of Claim 1 to the upper part of the entrance of a pop-up tent, wherein the upper part of the net is fixed to the upper part of the entrance of the pop-up tent so that the longer net faces the pop-up tent side and the shorter net faces the side where crows enter, and the lower end of the longer net is set to extend further out than the shorter net towards the side where crows enter, so that when crows roll up the shorter net, the crows will land on the longer net, making it difficult for them to roll up the longer net, thereby preventing crows from entering the pop-up tent and preventing crows from rummaging through the garbage inside the tent.
