By heating with the heat of hydration reaction of the exothermic substance, the gas generant is thermally decomposed, and the heat-volatile chemicals are released as smoke into the atmosphere.

2. Description of the Related Art A smoke device that is heated by the heat of hydration reaction of a heat-generating substance that heats when it comes into contact with water to release a heat-volatile chemical as smoke into the atmosphere has been widely used. That is, the smoke generating composition containing a smoking agent composition and a heat generating substance such as calcium oxide via a partition, by allowing it to stand in a water container containing a predetermined amount of water during use, after a while, The water in the water container infiltrates into the storage part of the exothermic substance such as calcium oxide in the smoke generating device, and the smoke agent composition is heated by the heat generated by the hydration reaction at this time, and the heat volatility of insecticides etc. It aims to control harmful insects by releasing the drug into the atmosphere.

When using this type of smoke generating device, it is necessary to measure the amount of water put in the water container to some extent accurately. If the amount of water contained in the water container is less than the predetermined amount, the hydration reaction of the exothermic agent such as calcium oxide will be insufficient, sufficient smoke will not be obtained, and more than the predetermined amount of water will be obtained. If it is excessive, the heat generation temperature cannot be sufficiently raised, and again it becomes difficult to obtain sufficient smoke. For this reason, in the past, the line of sight that indicates the appropriate amount of water was placed on the body of the water container, but when using this type of smoke generator, the water in the water container containing the water A method using a cup or the like has been conventionally used for the addition, and such a method inevitably resulted in an incorrect amount of water.

Further, in the conventional smoke producing product, both the smoke producing device and the water container have a columnar shape, and the space between the device and the water container is small. When the smoking device was inserted from above, it was difficult for the fingers to enter, and there was a case where the user had no choice but to drop it from the middle. For this reason, a part of water splashes and the hydration reaction is not performed with an appropriate amount of water, and in the worst case, smoke may not be sufficiently emitted. For this reason, if you try to make a water container that can fit your fingers sufficiently, the diameter of the water container itself will increase, and a wide space will be required for the transportation and storage of the product. Was difficult due to the nature of the product. Further, when the water container is provided with an upper lid, the upper lid has a hole portion in the upper cross section of the smoke producing apparatus for emitting substantially completely the smoke produced by the smoke producing apparatus. Need to have a larger opening than
If such a large opening is provided, the smoke generating device may jump out of the water container and the heated smoke generating device or the heated water may be scattered when the entire device falls. The present invention provides an upper lid for a water container that can be safely used even in such a case. Furthermore, if the smoke generator is placed in a water container containing water, the smoke generator will be about 30
When the temperature reached a high temperature of about 0 ° C. and the water container was placed directly on the floor and smoked, the floor could be deteriorated.

It is intended to provide a highly safe water container and a smoke-generating product using the same.

[0006]

In order to solve the above-mentioned problems, the inventors of the present invention have made earnest studies on the shape and structure of the water container of the smoke producing apparatus, and found that the shape of the cross section of the water container was substantially the same. The square shape makes it possible to safely and securely install the smoke generation device in the water container with almost the same size as the conventional cylindrical water container, and the external size of the water container is the same as the conventional one. Since it is about the same, we have found that the transportation and storage space in the distribution process can be reduced to about the same as conventional products. Further, it has been found that, by providing a step at or near the water weighing position at the bottom of the container body of the water container, the amount of water to be put into the water container can be accurately and unexpectedly measured easily and reliably. Furthermore, after carefully studying the temperature change at the bottom of the water container, it is possible to keep the temperature on the floor below the safety standard value by providing a resin pedestal of 2.5 mm or more at the bottom of the water container. Found.

That is, the present invention is characterized in that in a water container of a smoke producing apparatus which produces smoke by contacting with water, a step is provided at or near the water weighing position at the bottom of the container body. The present invention also provides a water container for a smoke generating device, and the present invention provides a water container for a smoke generating device that generates smoke by contacting water, wherein the cross section of the water container has a substantially square shape. Shape, preferably one side of the outer edge of a substantially square shape,
The present invention provides a water container for a smoke generating device, which is at least 18 mm or more. Further, the present invention provides a water container for a smoke generating device, which is in contact with water to generate smoke, and has a bottom surface. A pedestal projecting from the pedestal, preferably a pedestal made of resin, is provided, and the height of the pedestal is 2.5 mm or more. Further, the present invention generates smoke by contacting with water in which a smoke generator is housed in the water container upper lid suitable for the water container of the present invention and the water container of the present invention described above. It is intended to provide a smoke producing product.

More specifically, the present invention is an upper lid that is detachably attached to a water container of a smoke generating device that comes into contact with water to generate smoke, through which the smoke generating device can pass. It is characterized in that it has a ring-shaped size, the inner edge of which has an opening that is almost the same shape as the outer edge, and that ribs are installed on the inner edge of the opening to prevent the smoke generator from passing through. And a smoke producing product which produces smoke by contacting with water in which a smoke producing device is housed inside the water container of the present invention.

In order to accurately measure the amount of water to be put in the water container, it is preferable that the position of the weighing is easy to see and easy to see, and that the error of the weighing is small. Conventionally, the position where water is put is displayed by putting a scale line on the water container. It suffices to lift the water container to the eye position and measure the amount of water accurately, but this method complicates the operation and in many cases the method of pouring water from the top of the water container is adopted. Came. However, in this method, since water is poured from the top of the container, the scale line is difficult to see, and the amount of water is often inaccurate, so that a sufficient smoke producing effect cannot be produced. The first characteristic point of the water container of the present invention is, at or near the water weighing position at the bottom of the container,
That is, a step is provided. By attaching a discontinuous shape to the container instead of a line like a scale line, even when viewed from above the water container, the position of weighing can be visually recognized as a change in the shape of the container, so that the water can be easily and surely It has been found that the quantity can be accurately weighed.

The step in the water vessel of the present invention may be any step as long as it can be seen from above that the shape of the inner wall of the water container is discontinuous. More specifically, it is a step in which the cross-sectional area (S) of the water container changes discontinuously, more preferably abruptly, with respect to the depth (x) of the container. For example, as shown in FIG. 1, there may be a step substantially perpendicular to the container side wall.

FIG. 1 is a side view of an example of the water container of the present invention. The water container 1 is a container having an opening at the top, and the outer edge 9 of the opening, the upper side wall 2, the step 3, the lower side wall 4, and the bottom surface 5 are included.
And a pedestal 6, and the inside of the container is composed of a water container upper part 8 and a water container lower part 7 above the step 3. Ribs 10 for stably placing the smoke generator on the lower part 7 of the water container
Is provided. FIG. 2 is an elevation view of the water container 1 shown in FIG. In this example, the rib 10 provided on the bottom surface 5 is 8
The book is shown. The cross-sectional area of the water container 1 is sharply reduced at the step 3, and the step portion can be clearly seen from the upper part of the water container 1. In the example shown in FIGS. 1 and 2, the step 3 is provided substantially perpendicular to the side wall of the water container, but the step of the present invention does not have to be a sharp step as in this example. It suffices that the change in the cross-sectional area can be visually observed when viewed from above the water container, and an oblique step or a curved surface having an appropriate radius may be formed.

The rib 10 also has a function as a guide when the smoke generator is installed in the water container so that the smoke generator is safely and easily installed in the substantially central portion of the water container. is doing. For this reason, it is preferable that the rib is provided with a linear or curved guide slope.
Further, it is preferable to secure a certain area or more of the upper surface of the rib, and further take measures such as removing the corner of the rib. For example, it is preferable that the rib has a width of 1 to 5 mm and a corner of 0.5 to 2R. The number of ribs is not particularly limited, but is preferably 4 to 20. Furthermore, between the water container and the smoke generator packaging (for example, the top / side or bottom /
By installing a cushioning material such as paper or plastic on the side surface portion, it is possible to prevent damage to the product or the packaging material during transportation in the distribution process.

By providing such a discontinuous cross-sectional area change, surprisingly, when water is poured into the water container from above, the change in the water surface area of the water stored in the container can be clearly known. It was found that the amount of water can be accurately measured by a simple method. In the conventional weighing with a scale line, it is difficult to measure accurately because there is a judgment material only for the position of the scale, not the change in the area of the water surface, but according to the water container of the present invention, a step is provided. Since the area of the water surface changes abruptly at the step, it is possible to know the water level very clearly and to accurately measure water. That is, when we asked 60 monitors about the effect of providing a step on the water container, 73% of them said that it had an effect of being a measure for weighing. The results are shown in Table 1.

[0014]

[Table 1]

The step according to the present invention may be such that the change in the cross-sectional area is discontinuous, and in extreme terms, the cross-sectional area of the upper part of the water container is different from the cross-sectional area of the lower part of the water container.
It is preferable that the cross-sectional area of the upper part of the water container is larger than that of the lower part of the water container. In particular, when the shape of the cross section of the water container is a substantially square shape, the cross-sectional area becomes larger than that of the conventional cylindrical water container, so that it becomes difficult to obtain a sufficient water depth for a given amount of water. In addition, it is preferable that the cross-sectional area of the lower portion of the water container is small, because a weighing error due to a slight difference in water level becomes large. A preferable cross-sectional area of the lower part of the water container is 90 times that of the upper part of the water container.
% Or less is preferable, but not limited to this.
More specifically, it is 50% to 90%, preferably 70% to 90% of the cross-sectional area of the upper part of the water container.

The water container of the present invention may be provided with conventional scale lines in addition to the above-mentioned steps. The scale line is preferably provided immediately below the step or in the vicinity thereof. The scale line is preferably colored in a color different from the material of the water container, such as black. Such scale lines may be provided on the water container itself by embossing the water container itself or by printing with an inkjet printer, or may be printed and fixed on a film outside the water container.

Further, the present inventors secure a space between the smoke generating device to be put therein by making the water container into a substantially prismatic shape in contrast to the conventional cylindrical smoke generating device. By doing so, it becomes easier for the fingers to enter, and as a result, it is possible to install the device at the bottom of the water container while holding the smoke generating device, and the smoke generating device with reduced risk of water splashing Came to develop the water container of. An experiment was carried out by 60 monitors about the ease of putting in the smoke producing device by making the shape of the water container into a substantially prismatic shape. That is, using the water container of the present invention and a conventional cylindrical water container as a comparative example, the ease of putting the smoke generating device into 60 monitors was investigated. The results are shown in Table 2.

[0018]

[Table 2]

As a result, 43% of the monitors replied that the water container of the present invention was easy to put, whereas the comparative example had only 23%. Further, the monitor that answered that it was difficult to put in was 3% in the columnar one of the comparative example, but was 0% in the substantially prismatic water container of the present invention. As a result, the smoke generator can be put in very easily by making the shape of the water container substantially prismatic, and it is possible to significantly reduce the risk of water splashing when putting the smoke generator in the water container. all right. Since the container body of the water container of the present invention has a substantially prismatic shape, not only is it easy to put the smoke generating device in the water container, but it does not roll even if the water container is accidentally tumbled, and the upper lid Since a ring having internal ribs that can prevent the smoke generating device from popping out is provided in, the smoke generating device inside the water container does not pop out. Therefore, the smoke generation device can be used more safely. Further, the container body of the water container of the present invention has a substantially square columnar shape, so that the useless space is reduced during transportation, storage, or display at a retail store, and storage or display space is effective. Can be used for.

There is no particular limitation on the size and shape of the water container having a substantially rectangular prism shape according to the present invention, but the length of the diagonal line of the cross section is equal to the diameter of the smoke generating device and the width of two fingers supporting the smoke generating device. It should be more than the sum. Further, the depth is sufficient if it is deep enough to accommodate the smoke generating device. Since the water container having a substantially rectangular column shape of the present invention has a sufficient space for installing the smoke generating device on the bottom while holding the smoke generating device with fingers, it is slightly deeper than the conventional cylindrical water container. It may be designed. The water container having a substantially square column shape of the present invention has a substantially rectangular cross section, can secure the above-mentioned length in the diagonal direction, and has a high cross-sectional shape as long as it is upright and highly stable when falling. Although there is no particular limitation, it is preferable that at least a part thereof has a linear portion. More preferably, a shape in which each of the four sides has a linear portion can be mentioned. It is not always necessary to have curved portions, but it is preferable that the four corners are curved. The length of the straight line portion and the radius of the curved line portion are not particularly limited, and can be appropriately designed in consideration of erecting, stability at the time of falling, and the like.

According to a detailed study by the present inventors, it is preferable to have a straight portion of at least 18 mm or more on one surface of the outer peripheral edge of the substantially prismatic container, and the curved portions at the four corners have R of 15 mm or more. Preferably. However, the water container of the present invention is not limited to these. By designing the water container of the present invention as described above, the mechanical suitability of the lid mounting machine and the label machine is improved, and in consideration of the transportation process, at least 18 mm or more on one surface of the outer peripheral edge of the substantially prismatic container. By providing the linear portion, it is possible to achieve the effect of preventing rotation of the container due to collision between the containers during transportation.

The water container of the present invention preferably has a pedestal 6 under the bottom surface 5. The pedestal 6 is provided not only for stably installing the water container but also for preventing the heat generated when smoking is generated from being transmitted to the floor surface. It is required that the lowermost end of the pedestal 6, that is, the maximum temperature of the portion in contact with the floor surface is 80 ° C. or lower. According to the research conducted by the present inventors, the height of the resin pedestal 6 is 2 ° C. If it is 0.5 mm or more,
It has been found that the maximum temperature of the lowermost end of the pedestal 6, that is, the portion in contact with the floor surface can be set to 60 ° C. or lower. Thus, considering the effect of radiant heat on the floor material, the height of the pedestal is preferably 2.5 mm or more, and more preferably 3 to 5 mm because both thermal effect and stability can be achieved. In addition, the pedestal 6 may be appropriately perforated to improve air circulation,
You may make a break. Therefore, in the water container of the present invention, there is no fear that the floor will be deteriorated during or after its use, and the smoke generating device can be safely used.

The material of the water container body of the present invention may be an opaque material because the amount of water to be added can be simply and accurately weighed and put in, but it has heat resistance and
A transparent or semi-transparent material that can confirm the addition state of water from the outside is preferable, for example, polyethylene,
Polypropylene, polyethylene terephthalate (PE
Synthetic resins such as T) and polyvinyl chloride (polyvinyl chloride) can be mentioned, and among them, polypropylene is preferable. As a method for further improving the heat resistance of the water container, it is possible to adjust the degree of polymerization of the resin, mix an inorganic mineral substance such as calcium carbonate or talc, or increase the wall thickness of the container. it can. A preferable material for the water container of the present invention is that the deflection temperature under load at 0.45 MPa is 100 ° C.
As mentioned above, a resin having a temperature of 122 ° C. or higher is preferably used. Table 3 below shows the results of experiments on the heat resistance of water containers using resins having various deflection temperatures under load.

[0024]

[Table 3]

From these results, it is understood that when the deflection temperature under load at 0.45 MPa is less than 100 ° C., remarkable thermal deformation occurs, but at 100 ° C. or more, the thermal deformation also decreases. However, in order to prevent thermal deformation,
It can be seen that it is necessary to use a resin whose deflection temperature under load at 0.45 MPa is 122 ° C. or higher. Therefore, the present invention also provides a water container of a smoke-generating device made of resin having a deflection temperature under load at 0.45 MPa of 100 ° C or higher, preferably 122 ° C or higher.

The water container of the present invention may be made of resin or the like as it is, but it is preferably used after being covered with a film or the like. As such a film, any film having heat resistance and good printability may be used, but a heat-shrinkable film is preferable from the viewpoint of easy operation. In the conventional cylindrical water container, the radiant heat during smoking is almost uniform with respect to the film attached to the container body, and the heat shrinkage is balanced, so the film is relatively broken even during smoking. Although it is difficult, in a substantially prismatic column like the water container of the present invention, there is a difference in how the radiant heat is applied between the central portion of the body and the corners, so the heat balance becomes uneven, and if it does not have sufficient strength, it easily breaks. Therefore, it is preferable to use a heat-shrinkable film having high heat resistance such as polypropylene, PET, vinyl chloride, etc. Among them, a polyolefin-based film is the most preferable from the viewpoint of heat shrinkability and gas generated during incineration. As the polyolefin type, a linear or cyclic one, ethylene-propylene, or ethylene-
Examples thereof include copolymers such as propylene-butene.
Further, the heat-shrinkable film made of a cyclic polyolefin-based resin is more preferable from the standpoints of commerciality and mechanical suitability because it has excellent transparency and gloss and has a proper elasticity.

After the package of the smoke generating device is stored in the water container of the present invention, a smoke generating product can be obtained by sealing the opened upper part of the water container with a film material. In the smoke producing product of the present invention, a sealed water container may be further provided with an upper lid described later, if necessary. A preferable film material for sealing the opening in the upper part of the water container is one having a puncture strength of 1700 g or more (puncture tip 0.5R, 100 mm / min). As a method for sealing the upper part of the water container with a film material, for example, peelable packaging by thermocompression bonding can be performed. Further, from the aspect of adjusting the pressure inside the water container after sealing, a window portion such as a hole or a break may be appropriately provided in a part of the film or the water container. For example, a cut may be provided at the upper end of the water container. The shape of the window such as the cut may be arbitrary, as long as it has an area of a size capable of adjusting the pressure inside and outside the water container, and the number may be one or more and may be appropriately determined. You can The installation position is not limited to the upper end portion, and can be appropriately determined. As a preferable window portion, a width of 0.1 to 3.0 mm at the upper end portion, preferably 0.5
~ 1.5 mm, depth 0.5-3.0 mm, preferably 0.
A method of providing a cut of about 5 to 1.5 mm can be mentioned.

As the film material for sealing the smoke generating device, aluminum laminate packaging is used for the purpose of ensuring the quality stability of the product in distribution and preventing moisture of the smoke generating device. It is generally used, but by sealing the upper part of the water-soluble container with a film material, the product can be protected from external impact even if the aluminum laminate packaging of the smoke generating device is omitted.

The water container of the present invention may be used alone, but it is preferable to use an upper lid to prevent the smoke generating device from popping out during use. As the upper lid, a ring-shaped one having an opening through which the generated smoke can be discharged is preferable. The ring-shaped upper lid is
It is also required to have heat resistance since it is affected by the gas generated during smoking and radiant heat. The shape of the inner edge can be circular, polygonal, etc., but while preventing the smoke generation device from popping out when falling over during smoke, the opening should be as large as possible and the film material above the opening should be From the viewpoint of protection, it is preferable that the inner edge portion and the outer edge portion have substantially the same shape, and that the inner edge portion be provided with a rib for preventing the smoke generating device from popping out. In addition, the heat resistance can be further improved by increasing the thickness of the inner edge portion.

An example of the upper lid of the present invention is shown in FIG. FIG. 3 is a plan view of an example of the upper lid of the present invention. The upper lid 20 has an outer edge portion 2.
1 and an inner edge portion 22, and has an opening 25 having substantially the same shape as the outer edge portion 21 at the center. The opening 25 is provided with a rib 24 for preventing the smoke generator from popping out. In this example, since the opening portion 25 is designed to be large, the smoke generating device can pass through without change, and the smoke generating device may pop out during use. The ribs 24 can prevent the smoke generating device contained in the water container from popping out. Also,
The upper lid 20 is provided with a groove 23 having substantially the same shape as the outer edge portion 21. The groove 23 is formed so that the surface of the upper lid 20 is uneven, and the pedestal 6 in FIG. 1 can be accommodated in the groove 23. Therefore, when the water container 1 is stacked on the upper lid 20, the pedestal 6 of the upper water container 1 is replaced by the lower lid 2 of the lower container.
The product fits in the groove 23 of 0, and the products can be stably stacked.

The material of the upper lid is polypropylene, P
Examples of the heat resistant material include ET and vinyl chloride. In order to further improve the heat resistance, inorganic mineral substances such as calcium carbonate and talc can be added.

In the water container of the present invention, for example, a storage portion for a heat-generating substance which generates heat upon contact with water is molded so as to surround the storage portion for the smoke agent composition, and an opening for water passage is provided at the bottom. And a bottom plate having a base material, and the bottom wall and / or side wall of the smoke agent composition storage portion is heated by the heat of hydration reaction of a heat generating substance to generate a smoke. It can be widely and effectively used as a water container for a smoke generating device, and as a water container for various smoke generating devices having the same principle of smoke generation.

A smoke producing product comprising the water container of the present invention and the smoke producing device can be obtained by enclosing the smoke producing device described above inside the water container of the present invention and appropriately packaging it. it can. The smoke generating device used in the water container of the present invention has a substance that generates heat in contact with water such as calcium oxide in the heat generating substance storage part, and contains a pesticide as a smoke agent composition. preferable. The insecticide in the present invention refers to not only insecticides but also insecticides, acaricides, bactericides, and fungicides that control or control pests. For example, pyrethroid insecticides such as permethrin, phenothrin, pyrethrin, cifenotrin, resmethrin, and plaresulin, organophosphorus insecticides such as fenitrothion, fenthion, diazinon, DDVP, carbamate insecticides such as metoxadiazone, propoxur, and sterilization of triazine.
