Insect Net with Folds to Prevent Escape

Abstract

To provide an insect net having a function of retaining insects and preventing them from escaping, by focusing on cases where captured insects move along the edge of the net and escape. The mesh has a flexible pleated structure arranged around the edge, which acts as a physical barrier to prevent insects from escaping when they try to move downward. The pleats are flexible and can hold insects without damaging them, contributing to improved capture efficiency and safety.

Description

[Technical Field]

[0001] This invention relates to an insect net, and more particularly to a structure that has a function of preventing insects from escaping. [Background technology]

[0002] Conventional insect nets are prone to gaps at the edges of the net, which often allow captured insects to crawl through and escape. Especially when used on the ground or in grass, insects tend to move downward immediately after being caught, making complete capture difficult. Furthermore, the structure of the net alone is not enough to prevent small, fast-moving insects from escaping, which is one of the factors that reduces capture efficiency. As of July 2025, no publicly known documents relating to "structures for preventing insect escape" related to this invention could be found in literature and patent databases, etc. However, the above-mentioned problems are clear from the experience and observation of using ordinary insect nets, and it is understood from everyday use that the conventional technology was insufficient in terms of preventing escapes.

[0004] [Non-Patent Document 1] (Not specified) Summary of the Invention [Problem to be solved by the invention]

[0005] With conventional insect nets, even if insects are caught, they often move along the edge of the net and escape to the ground or into the grass, and there is no structure to prevent them from escaping downwards.Crawling insects such as cockroaches and spiders can easily move out, so there are issues with insufficient capture efficiency and retention. [Means for solving the problem]

[0006] In this device, a flexible pleated structure is placed around the edge (frame) of the insect net, physically blocking the insect's path of movement. The pleats are made of a soft material and are attached so that they hang down, so when an insect tries to crawl along the edge of the net and move downward, it bumps into the pleats and is prevented from moving out of the net. This gives the net a natural escape prevention function without the need for a special opening and closing structure. [Effects of the Invention]

[0007] It reduces the escape rate of captured insects, making it particularly effective against small insects and insects that crawl on the ground.It also blocks insects' escape routes even when used near the ground, making it ideal for insect collection and observation. [Brief explanation of the drawings]

[Figure 2] This is a reference diagram showing the device in use, showing how the pleats prevent insects from escaping outside the net. DETAILED DESCRIPTION OF THE INVENTION

[0009] The insect net of the present invention comprises a circular or oval frame and a net member attached within the frame. A flexible, strip-shaped "pleated member" is arranged around the periphery of the frame, extending downward from the frame. The pleated member is made of EVA resin, soft PVC, nylon fiber, nonwoven fabric, or other materials, and has a certain thickness and flexibility to block insect movement. The pleated member can be attached by sewing, gluing, or by clamping it to the frame, achieving both robustness and mass production. The net is designed to prevent insects from escaping downward along the edge of the frame after being captured, thereby improving capture efficiency. If necessary, the pleats can be arranged in multiple layers to provide greater retention. [Example]

[0010] In this example, the insect net is composed of a circular frame with a diameter of about 30 cm and a nylon mesh member. A flexible, pleated band member with a width of about 2 cm is attached around the outer periphery of the frame. The pleats are made of EVA resin and are positioned so that they hang naturally downward from the frame when the net is in use. The pleats are sewn to the outer periphery of the frame, creating a physical barrier to insect movement. When this net was used to capture pests and collect insects, it was found that the escape rate of captured insects was significantly reduced compared to conventional nets, and the holding power was improved, especially when the insects were in contact with the ground. Furthermore, because the pleats are made of a flexible material, they did not hinder the insects' movement and could be handled without damaging them when observing or transferring them.

Claims

[Claim 1] 1. An insect net characterized in that a flexible pleated structure is provided around the edge of the net.
