Embodiment Construction

[0069] figure 1 The total length of the cardboard coil shown in is 1.8m, the width is 5mm, and the burning speed is 6.6×10-6m.s -1 (0.4cm.min - 1). The coil can thus burn for 7.5 hours.

[0070] Fig. 2 (a) to (d) are a group of mosquito-repellent coils of other styles made according to the invention.

[0071] figure 1 The coil 2 of the middle mosquito coil has a rectangular cross section. The width, thickness, and density of the coil 2 greatly affect the burning rate.

[0072] image 3 Medium is in coil width 5mm and density 5709kg.m -3 (0.57g.cm -3 ) is constant, the curve graph of the burning speed and the thickness of the cardboard coil.

[0073] As the thickness of the cardboard coil increases to 1.8mm, the burning speed also increases from 6000s.m -1 increased to 15000s.m -1 (1min / cm to 2.5min / cm). When the thickness is greater than 1.8mm, the combustion becomes unstable and has a significant tendency to self-extinguish.

[0074] The coil 2 of the mosquito-rep...

Abstract

A substance delivery device includes a combustible paperboard strip and at least one substance toxic to insects and a perfume. The delivery device can take the form of a coil and includes a flexible backing sheet for supporting the combustible paperboard strip. The flexible backing sheet is not capable of combustion. Additionally, the material of the paperboard strip can include a combustion promoter.

Description

technical field [0001] The present invention relates to a substance transfer device comprising a cardboard strip containing at least one insecticidal substance or one fragrance. The invention also relates to methods of manufacturing such devices. Primarily, but not exclusively, the present invention relates to a mosquito coil (mosquito coil) comprising a cardboard coil impregnated with an insecticide, and a method of producing such a mosquito coil (mosquito coil). Background technique [0002] US-5447713 discloses a kind of mosquito-repellent incense, and it is made of wood fiber and / or sawdust and binder. The mixture is backlogged into a rigid board with coils. Wood fibers and wood chips remain dispersed and separate but are held together by adhesives. The use of adhesives gives the coils mechanical stability, but also implies a brittleness of the coils. Coils made of such resin-bonded cardboard are likely to be destroyed during transportation or continuous use by consu...
