Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a water container suitable for evaporating chemicals such as insecticides and heating foods,
The present invention relates to a kit of a water container and a self-heating canister, and a composition capable of being heated and evaporated by them.

[0002]

2. Description of the Related Art Conventionally, as a water heating exothermic vaporizer, a self-heating can containing a water heating exothermic substance such as lime is contained in a water container. As the water container, an upper open type container in which a peripheral wall is erected on the bottom wall is generally used. The open upper part of the water container is sealed by a sealing member, and the upper lid is detachably attached. An opening is provided at approximately the center of the upper lid, and the opening is closed by a paper lid sandwiched between the upper lid and the water container. The water container is generally formed of a transparent or translucent resin such as polypropylene or polyethylene. A water level line (for example, a black line) that is a standard for pouring water is printed on the outer surface of the peripheral wall of the water container.

In such a water-heating exothermic vaporizer,
Before use, first remove the top lid, paper lid and sealing member from the water container. Next, a predetermined amount of water is poured into the water container so that the water level line printed on the outer surface of the peripheral wall of the water container is equal to the water level of the poured water. Then, the self-heating can is put in and the upper lid is attached to the water container again. When the hydrothermal exothermic substance in the self-heating can reacts with water to generate heat, the substance to be heated is heated by the heat and, for example, the medicine is evaporated to the outside from the opening of the upper lid.

SUMMARY OF THE INVENTION It is desired to simplify the manufacturing process of a water container or the like of a water heating exothermic vaporizer for cost reduction. Further, it is desired that the water-heat exothermic vaporizer has an excellent pest control effect when an appropriate amount of water is poured. The present invention has been made in view of such circumstances, and an object thereof is to provide a water container that is easy to manufacture, a kit of a water container and a self-heating can, and a composition capable of being heated and evaporated by them. To do.

[0005]

As a result of intensive studies on simplifying the manufacturing process, the present inventors have found that the water level line printing process can be omitted by using the following configuration. A water container that is formed by arranging a peripheral wall on the bottom wall and contains a self-heating can containing a hydrothermal heating substance and is filled with a predetermined amount of water. A water container in which the marked pattern is provided on the peripheral wall as a water level line. The water container according to the above, wherein the water level line is a textured surface of the molding die transferred. When the self-heating can is stored, it has an inner diameter such that a gap is formed between the inner surface of the peripheral wall and the outer peripheral surface of the self-heating can, and the inner surface of the bottom wall and the bottom surface of the self-heating can. The water container according to the above or above, which is configured so that a gap is formed therebetween. It is a resin molded product in which a peripheral wall is erected on the bottom wall, and the pattern transferred from the mold is a water container provided on the peripheral wall as a water level line, and a water heating exothermic substance is housed inside the water container. A water container and a self-heating can kit characterized by having a self-heating can. A composition capable of being heated and evaporated by a water heating exothermic vaporizer equipped with the water container and the self-heating can kit described above, wherein the egg contains methoxadiazone and phenothrin as active ingredients. Hatching suppression composition.

As the water container, one having a cylindrical peripheral wall is generally used, but it has been complicated to print the water level line on the cylindrical surface of such a peripheral wall. On the other hand, if the water level line is deleted, the user will put too much water and the desired performance of the water heating type evaporator cannot be exhibited. Therefore, the water line cannot be deleted. Therefore, if the above configuration is adopted, since the water level line has already been transferred to the water container taken out from the molding die, a complicated printing process can be omitted. Moreover, the usability is not reduced. In this way, it is possible to reduce the cost of the water container, and by extension, the water vaporization heat type evaporator.

If a textured surface is provided on the mold and the textured surface is transferred to a water container, the water container has a pattern like frosted glass. The user can recognize this pattern as the water level line. In addition to providing a textured surface on the mold,
Various variations are conceivable, such as providing the mold with irregularities and transferring the irregularities to a water container. In addition,
Using the water container and the self-heating can, a water heating exothermic vaporizer can be constructed as follows. That is, a self-heating can containing a water heating exothermic substance and a water container having a bottom wall with a peripheral wall provided upright to accommodate the self-heating can and to pour a predetermined amount of water In the mold evaporator, the water container is a resin molded product, and the pattern transferred from the mold is provided on the peripheral wall as a water level line.

Further, by heating and evaporating a composition containing methoxadiazone and phenothrin as active ingredients by the above-mentioned hydrothermal exothermic vaporizer, an effect of inhibiting egg hatching of fleas, indoor dust mites and the like can be obtained. You can The composition can be formulated into granules and the like together with an organic foaming agent, a binder and the like. By heating and evaporating this composition, it is possible to obtain a pest control effect that has not been obtained in the past. The composition can be used as various preparations such as an aerosol, a liquid, a granule, a coating agent, etc., in addition to being evaporated by heating. Furthermore, it also has an insecticidal effect against various harmful insects such as cockroaches, mites and fleas. The composition preferably contains 1 wt% to 20 wt% of methoxadiazone, more preferably 5 wt% to 15 wt%. Phenothrin is preferably contained in an amount of 1 to 20% by weight, more preferably 5 to 15% by weight. Such a composition exhibits an egg hatching inhibitory effect on eggs of fleas such as cat fleas and indoor dust mites such as leopard mites. Here, the egg hatching inhibitory effect also includes an ovicidal effect.
