Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest control agent or the like stored in an inner storage portion of a double-formed drug container by bringing an exothermic agent stored in the outer storage portion into contact with water. The present invention relates to a drug evaporation container that heats and evaporates a drug.

[0002]

2. Description of the Related Art As a device for controlling harmful insects such as cockroaches and mites that live indoors, a chemical cup is provided inside a can having a bottom through which water can enter, and a harmful insecticide that evaporates when heated is used as a chemical agent. For a drug container that is housed in a cup and that stores an exothermic agent that causes an exothermic reaction upon contact with water such as quicklime in the space between the drug cup and the can body, place the drug container therein. BACKGROUND ART A container unit for evaporating chemicals, which is attached with a cup-shaped water receiver for placing, has been conventionally commercially available.

In such a device, a predetermined amount of water is put in an attached water receiver, a medicine container is placed in the water receiver, and the bottom of the medicine container is immersed in water. By doing so, water that enters from the bottom and the exothermic agent react to generate heat, and the heat heats the drug to evaporate, but at that time, if the amount of water to be put in the water receptor is too large, The fever suddenly progresses and the internal pressure of the drug container rises abnormally, causing the risk of explosion, etc.On the other hand, if the amount of water put in the water receptor is too small, the transpiration effect of the drug will be insufficient,
Furthermore, depending on the place of use, water may not be readily available.

Therefore, in order to deal with such a problem, a drug container containing a drug and a heating agent in a double container as described above is inserted into a water receiver which is hermetically closed by an easy-open lid. , A synthetic resin diaphragm whose outer edge is wound and stretched around a water receiver is exposed at the upper end of the drug container, and the diaphragm has a cross-section upward opening groove shape having a pull tab and a bottom portion torn open by pulling of the pull tab. By forming a water reservoir surrounding the water reservoir and surrounding the water reservoir in the annular space between the water receiver and the drug container, the pull tab is pulled during use to tear and open the water reservoir. BACKGROUND ART A chemical vaporization container in which is supplied from a water reservoir to a heat generating agent via a water receiver has been conventionally known. (See Japanese Utility Model Publication No. 4-25979)

[0005]

By the way, in the conventional chemical evaporation container as described above, a predetermined amount of water can be supplied to the exothermic agent at the time of use, but the water receiver is hermetically closed by the easy open lid. Since the entire drug container and the water reservoir are stored together, if water leaks from the water reservoir for any reason, an exothermic reaction will occur in the sealed water receiver, There is a risk that the air will be heated and expanded in the container, and the pressure in the container will rise, resulting in blowing off the easy-open lid.

An object of the present invention is to solve the problems of the conventional chemical vaporization container as described above. Specifically, the simple destruction portion is destroyed to store a predetermined amount of water stored in advance in the chemical. By supplying to the exothermic agent in the container, it is possible to stably evaporate the drug and prevent contact with the simple destruction part during handling, and by any chance the water stored before use can be removed. An object of the present invention is to provide a drug vaporization container unit capable of safely handling and managing products without affecting the drug container even if it leaks.

[0007]

In order to solve the above-mentioned problems and to achieve the object, the present invention provides a can body having a bottom portion into which water can enter, as set forth in claim 1 above. , A drug cup containing a drug that evaporates when heated,
By fixing the flange portion projecting to the peripheral edge of the upper end opening to the upper end of the can body of the can body, it is installed so as to form a space between the can body and the bottom part of the can body. In the space between them, a medicine container containing a heat-generating agent that generates heat when contacted with water, and a bottom and side walls formed by a double wall form an overall cup shape, and the inner and outer walls of the double wall A predetermined amount of water is stored in the closed space defined between the water storage container and a simple destruction portion for communicating the closed space to the outside, and a water storage container formed on the inner wall of the bottom. However, the drug container and the water container are combined in such a manner that the drug container and the water container are detachably fitted so that the cup-shaped water container covers at least the lower portion of the drug container which is wholly packaged in a waterproof bag. It is characterized by being.

Further, in the chemical vaporization container unit as described above, as described in claim 2, a simple destruction portion having a protrusion for destruction operation in a central portion of the inner wall of the bottom portion of the water storage container. Is formed, and a protrusion for mounting the bottom of the drug container is formed in the peripheral portion thereof, and the height of the protrusion is equal to or higher than the height of the upper end of the protrusion for breaking operation. It is characterized by.

Further, in the chemical vaporization container unit as described above, as described in claim 3 above, at least one or more, at least one hermetically sealed space and the outside of the water storage container are provided on the upper part of the water storage container. A vent hole communicating with the vent hole is provided, and the vent hole is sealed by a peelable seal material.

Further, in the chemical vaporization container unit as described above, as described in claim 4, after the bottom outer wall of the water storage container is filled with water from the bottom of the inverted water storage container, It is characterized in that it is attached to the main body of the water container.

[0011]

[Operation] With the above configuration, before using it,
The simple destruction part of the water storage container is completely hidden from the outside by the chemical container, which prevents the simple destruction part from being accidentally destroyed during the handling of the product. Even if the water contained in the closed space of the device leaks, the entire drug container is packaged in a waterproof bag, so the leaked water will not come into contact with the exothermic agent. No exothermic reaction will occur.

In use, when the fitted medicine container is separated from the water storage container and the simple destruction portion of the inner wall of the bottom of the water storage container is destroyed, it is stored in the sealed space of the water storage container. A certain amount of a fixed amount of water will flow out into the water storage container, and if the drug container with the packaging bag removed is placed inside the water storage container again, it will flow out into the water storage container at a constant rate. A certain amount of water enters the can from the bottom of the can of the medicine container and reacts with the exothermic agent, and the exothermic reaction of this certain amount of water and the exothermic agent heats the medicine in the medicine cup in an appropriate state to evaporate. To do.

According to the structure as described in claim 2, even though the protrusion for breaking operation is projected in the simple breaking portion, the medicine is not fitted when the medicine container and the water container are fitted. It is surely prevented that the bottom of the container comes into contact with the breaking operation projection and breaks the simple breaking part.

Further, according to the structure described in claim 3, by peeling the sealing material, air flows in from the ventilation hole and atmospheric pressure acts on the water surface of the sealed space portion, so that the simple destruction is performed. The water will flow out smoothly from the inner part, especially if the space between the inner wall and the outer wall of the enclosed space is narrow and the upper end of the enclosed space is filled with water, destroy the simple destruction part. Although water may hardly drop due to the surface tension, the presence of the vent holes surely prevents such non-fall of water.

Further, according to the structure described in claim 4, it is possible to easily form the closed space portion of the cup-shaped water container having the double wall as a whole, and
When a predetermined amount of water is filled in the closed space, the injected water can be received over a wide area, and the position of the water supply pouring part to be filled and the pouring part of the water storage container 4 can be aligned. You don't have to be strict.

On the other hand, the drug cup 24 made of metal inserted through the upper opening thereof is in a state where the space 6 is formed between the can body 22 and the bottom plate 23 of the can body 21 and the drug cup 24. The flange portion 24a protruding to the periphery of the upper end opening and the upper end portion of the can body 22 are integrally fastened by being wound together.

In the interior 5 of the medicine cup 24, a medicine (not shown) such as an insecticide that evaporates by heating is stored, and a space portion between the can 21 and the medicine cup 24. A heat generating agent (not shown) such as quick lime that heats up due to contact with water is stored in 6, and the heat generating agent falls off from the water passage hole 23a on the upper surface of the bottom plate 23 of the can body 21. A non-woven fabric 25 or the like for preventing the above is placed, and a seal lid 26 is provided on the upper opening of the drug cup 24 containing the drug.

The seal lid 26 may be detachable so as to be removed at the time of use, but in this embodiment,
Although not shown in detail, a laminate of a thin film of vinyl-based synthetic resin that can be dissolved by the heat of the evaporated drug is used on aluminum laminated paper provided with an appropriate number of evaporation holes through which the evaporated drug passes. However, the seal lid 26 is used without removing it, and the thin film of synthetic resin is melted by heat to evaporate the drug from the hole of the aluminum laminated paper.

FIG. 3 shows the water container 4 in the container unit 1, which is composed of a double wall bottom and side walls so that a container recess 7 into which the drug container 2 can be inserted is defined. Is molded into a cup shape, and the main body portion 40 excluding the bottom lower surface 41 is integrally molded with a synthetic resin such as styrene, and a heat seal material 41 made of a laminate of aluminum foil and synthetic resin is formed as a bottom lower surface thereof. It is integrally welded, and its side wall has a double-wall structure with an inner wall 43 and an outer wall 45 of synthetic resin, and its bottom has a double-wall structure with an inner wall 42 of synthetic resin and an outer wall of the heat seal material 41. Has become.

The water container 4 having the double-wall structure has the inner walls 42 and 43, the upper end wall 44, and the outer walls 41 and 45.
An enclosed space 8 is defined, which is in communication with the whole,
A predetermined amount of water is stored in this closed space portion 8.

Further, on the bottom inner wall 42 of the water container 4,
A simple breaking portion 46 having a protrusion 46a for breaking operation is formed in the central portion thereof, and a protruding portion 47 for mounting the bottom portion of the drug container 2 is formed in the peripheral portion thereof, and the height of the protruding portion 47 is high. The height is equal to or higher than the upper end of the breaking operation protrusion 46a. In this embodiment, the protrusion 47 is formed continuously in a ring shape, but it may be formed as a plurality of independent protrusions.

Further, the inner wall 43 of the side wall of the water container 4
The upper end wall 44 connecting the upper end of the outer wall 45 with at least one vent hole 48 that communicates the closed space 8 with the outside.
The ventilation hole 48 is closed by a peelable seal material 49 having a waterproof property.

The position of the vent hole 48 is such that the upper end wall 44 is filled with water when the upper end of the closed space 8 is filled with water.
However, if it is not limited to the upper end wall 44, it may be provided anywhere as long as it is above the water surface of the water contained in the closed space 8.

As shown in FIG. 1, the medicine container 2 and the water container 4 having the above-mentioned structure are made of a water-proof and moisture-proof aluminum which is the whole medicine container 2 containing the medicine and the exothermic agent. After the bag 3 made of a material such as foil is hermetically packed, the medicine container 2 is stored in the storage recess 7 of the water storage container 4.
The drug container 2 is packaged by inserting it into the container from above.
The container unit 1 is a state in which the water storage container 4 and the water storage container 4 are integrally fitted, and the container unit 1 is boxed in that state, or, as shown in the drawing, the entire shrink unit 50 is made of shrink material. By shrink-wrapping, the unit state is fixed and then packed in a box, which is then sold as a product.

The operation and effect of the container unit for chemical evaporation of this embodiment having the above structure will be described below.

First, at the time of manufacture, since the water container 4 is formed by welding the heat seal material 41 to the bottom lower surface of the integrally molded main body portion 40, the whole is in the shape of a cup having a double wall. The container can be manufactured relatively easily, and when the predetermined amount of water is filled in the closed space portion 8, the injected water can be received by the entire bottom lower surface of the large area, and the water to be filled can be received. It is not necessary to strictly align the position of the supply / pouring part with the pouring part of the water storage container 4.

When the container unit 1 is assembled, since the projecting portion 47 is formed on the bottom inner wall 42 of the water container 4, the drug container 2 is inserted into the container recess 7 of the water container 4 from above. When fitted together, the bottom portion of the drug container 2 has a protrusion 46a for breaking operation of the bottom inner wall 42.
It is surely prevented that the simple destruction portion 46 is accidentally destroyed by touching.

Further, at the time of product management and sale, the simple destruction portion 46 formed on the inner wall 42 of the bottom of the water container 4 is completely hidden from the outside by the drug container 2, so that the product is used. It is impossible to touch the destructive operation protrusion 46a except when the simple operation of the destructive operation portion 4 due to mischief or malfunction.
6 is prevented from being destroyed, and further, by shrink-wrapping the entire container unit 1 with the shrink material 50, it is possible to completely prevent the fitting between the medicine container 2 and the water storage container 4 from coming off during transportation, and , Water storage container 4 during display at the store
Can be completely prevented from being mischievous.

Further, even if water leaks out from the closed space 8 of the water container 4 before use, the water leaks because the medicine container 2 is entirely covered with the waterproof bag body 3. The water does not come into contact with the exothermic agent contained in the medicine container 2, and the exothermic reaction does not occur accidentally except when in use.

When the medicine is evaporated and used, the fitted medicine container 2 is separated from the water container 4 and
By destroying the simple destruction portion 46 of the bottom inner wall 42 of the water storage container 4 by the destruction operation projection 46a, as shown in FIG. 4, a predetermined amount of water stored in the closed space portion 8 of the water storage container 4 can be obtained. A certain amount of the storage recess 7 of the water storage container 4
It will be leaked in.

At this time, the atmospheric pressure acts on the water surface of the closed space 8 by peeling off and removing the sealing material 49 blocking the ventilation hole 48 formed in the upper end wall 44 of the water container 4. Water flows out smoothly from the closed space portion 8 of the water storage container 4 into the storage recess 7, and in particular, in order to make the entire water storage container 4 compact, the interval between the inner wall 43 and the outer wall 45 is narrowed. Therefore, even when the upper end of the closed space portion 8 is filled with water, the presence of the vent holes 48 can reliably prevent non-drop of water due to surface tension.

Thereafter, as shown in FIG. 5, when the medicine container 2 from which the bag body 3 has been removed is placed again in the accommodating recess 7 of the water accommodating container 4, a certain amount of water that has flowed out into the accommodating recess 7 becomes The water passage hole 23a of the bottom plate 23 of the can body of the medicine container 4 and the non-woven fabric 2
Since it penetrates into the space 6 of the can body 21 through 5 and reacts with the heat generating agent contained in the space 7, a stable heat generation state can be obtained by the reaction of this constant amount of water and the heat generating agent. The medicine stored in the inside 5 of the medicine cup 24 is heated in an appropriate state and evaporated through the evaporation hole 26a of the seal lid 26.

FIG. 6 shows another embodiment of the container unit for chemical evaporation of the present invention. Compared to the embodiment shown in FIG. 1, the chemical container 2 and the water container 4 are integrated. In the fitted state, the top surface of the drug container 2 (strictly speaking, the top surface part of the bag body 3 for packaging the drug container 2) and the water storage container 4
The difference is that the upper end wall portion of the is configured to be substantially horizontal.

In this embodiment, in addition to the effects of the above-mentioned embodiment, the load applied to each container unit 1 is small when the container units 1 are stored in a large box in a plurality of stages.
In other words, even when stacked in multiple stages, a sense of stability increases,
Since there is no fear of damaging (breaking) the shrink material 50 or the heat sealing material 41 of the upper container unit 1 at the corners of the drug container 2 of the lower container container unit 1, it is possible during transportation or at the time of sale. When it is expected that the container units 1 are stacked in multiple stages and housed in a box, it is preferable to adopt the configuration as in this embodiment.

Although the respective embodiments of the container unit for chemical vaporization of the present invention have been described above, the present invention is not limited to the above specific structure, and, for example,
As for the water storage container 4, the material is not limited to styrene as long as the water storage container itself is capable of hermetically storing water and a closed space portion having a simple breakage portion is formed. As for the structure, the bottom surface of the bottom part may be formed with a detachable lid, or the entire water storage container may be integrally formed with synthetic resin. Needless to say, it is possible to change the design as appropriate, such as a partial double wall structure that does not cover the entire double wall structure.

[0038]

According to the chemical vaporization container unit of the present invention as described above, a predetermined amount of water stored in advance can be supplied to the exothermic agent of the chemical container by breaking the simple breaking portion. As a result, it is possible to cause the exothermic agent to always react in a constant exothermic state to stably evaporate the drug, and to prevent accidental destruction of the simple destruction part during the handling of the product, and, in the unlikely event, Even if the stored water leaks carelessly, the exothermic agent stored in the medicine container does not react with it, so that the product can be handled and managed very safely.
