Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insect repellent which can be stored together with clothes in a transparent or translucent storage container such as a garment case and the end time of the medicinal effect can be judged from the outside of the storage container, that is, without taking out from the storage container. Regarding

[0002]

2. Description of the Related Art Conventional insect repellents are obtained by compressing paradichlorobenzene or naphthalene into a non-woven bag and encapsulating it in a bag made of non-woven fabric or impregnating a thick filter paper with a liquid insect repellent and enclosing it in a container made of molded non-woven fabric. There were things.

[0003]

However, when these insect repellents are stored in a storage container such as a costume case and used, the insect repellent should be taken out from the storage container in order to determine whether or not the drug has run out. There must be. However, the fact is that this work is troublesome and often forgotten. Therefore, there has been a problem that clothes are eaten by insects. INDUSTRIAL APPLICABILITY The present invention is used by being stored in a storage container such as a transparent or translucent clothing case, and the replacement time is not delayed because the end time of the drug effect can be determined from the outside of the storage container, that is, without removing from the storage container. It is intended to provide an insect repellent.

[0004]

In order to solve the above problems, in the present invention, a liquid insecticide is impregnated into a substrate having a flat plate shape and provided with a concealing layer on at least one surface. The carrier is encapsulated in a packaging material composed of a non-woven fabric permeable to the liquid insect repellent and a plastic film or sheet having a transparent or semi-transparent portion so that the concealing layer faces the plastic film or sheet. It has the following configuration.

In the above-mentioned constitution of the present invention, the substrate is a paperboard, a paper material including a synthetic fiber mixed paper, a non-woven fabric,
Inert insect repellents such as felt-like fabrics and inorganic fibers,
Any material can be used as long as it can hold the insect repellent and transfer the insect repellent to the concealing layer according to the volatilization of the insect repellent.

The hiding layer is preferably a layer containing a white or light colorant or a layer having a roughened surface. For example, an inorganic material such as amorphous silica, kaolin, calcium carbonate or pulp powder. It can be formed by mixing a white colorant, which is an organic material, with a suitable binder, and applying this to the upper surface of the substrate.

Examples of the liquid insect repellent which can be impregnated into the substrate include pyrethroid type agents.

As the packaging material, the non-woven fabric is polyester,
Examples thereof include polypropylene, polyethylene, and a mixture thereof, as long as the insect repellent is inert and the insect repellent can be vaporized to the outside of the packaging material.
In addition, the transparent or translucent plastic film or sheet may be one that can adhere to the non-woven fabric and does not substantially volatilize the insect repellent agent as compared with the non-woven fabric.

[0009]

The insect repellent having the above structure is stored in a transparent or translucent clothes container or the like at a position where the surface of the plastic film or sheet having the transparent or translucent portion can be identified through the wall surface of the container. Since the carrier is encapsulated so that the hiding layer faces the plastic film or sheet, the hiding layer can be visually observed from the outside through the wall surface of the storage container by storing in this way, and the time to replace the insect repellent can be determined. it can.

When the substrate is impregnated with the liquid insect repellent (at the beginning of use), the substrate is not only paper material including paperboard and synthetic fiber mixed paper, but also non-woven fabric, felt-like woven fabric, inorganic fiber or the like. Since it is made of the above material, the insect repellent is diffused and retained on the entire substrate. In addition, the concealing layer is, for example, an inorganic material such as amorphous silica, kaolin or calcium carbonate, or a white colorant such as an organic material such as pulp powder,
Since a suitable binder is mixed and applied on the upper surface of the substrate, the liquid insect repellent held on the substrate also penetrates into the masking layer and is transparent depending on its low refractive index against light. Be converted. This phenomenon is similar to, for example, the principle of becoming transparent when water drops adhere to frosted glass, and the principle of water writing used when practicing calligraphy.

When the use is started, the liquid insect repellent impregnated in the substrate is gasified and volatilized on the surface of the substrate, passes through the nonwoven fabric, and diffuses in the container. When this volatilization phenomenon is constantly performed, the liquid insect repellent in the substrate continues to migrate to the surface, and eventually volatilization ends, but when the volatilization ends, the liquid insect repellent that has permeated the concealing layer. Since the drug is not present, the hiding layer becomes opaque.

That is, the time when the hiding layer becomes opaque (when it returns from the transparent state to white) is the end of the effect of the insect repellent. This change means that if the insect repellent is stored in a transparent or semi-transparent storage container at a position where the surface of the plastic film or sheet having a transparent or semi-transparent part can be identified through the wall of the storage container, the insect repellent does not have to be taken out from the storage container. Is also visible from the outside.

[0013]

An embodiment of the present invention will be described below with reference to the drawings. That is, FIG. 1 is a cross-sectional view showing the first embodiment of the present invention, and the insect repellent 1 is constituted by enclosing a carrier 2 in a packaging material 3. The carrier 2 is obtained by impregnating a pyrethroid-based liquid insect repellent 4 into a base 2a made of a filter paper formed by compressing pulp powder into a flat plate shape.
A colored surface 2b is provided on one surface of the base body 2a by coloring the surface, and an amorphous silica mixed with an appropriate binder is applied to the upper surface of the colored surface 2b to form a hiding layer. 2c is provided.

The packaging material 3 comprises a non-woven fabric 3a and a transparent plastic film 3b. The non-woven fabric 3a is a non-woven fabric sheet formed in a shallow dish shape by a press machine. The bottom 5 has projections 6 at four corners and at the center. Is provided. The tip of the protrusion 6 is coated with a fluorine resin in order to prevent the liquid insect repellent 4 from penetrating into the nonwoven fabric 3a in a liquid state.

The carrier 2 is arranged so that the surface opposite to the colored surface 2b faces the protrusion 6 provided on the non-woven fabric 3a, and the respective ends of the non-woven fabric 3a and the transparent plastic film 3b are heat-bonded. As a result, it is enclosed in the packaging material 3. Therefore, the colored surface 2b faces the inner surface of the transparent plastic film 3b.

Adhesive seals 7 (double-sided tape) are attached to the upper surface of the transparent plastic film 3b at two locations. The adhesive seal 7 is covered with a cover body (not shown) for removing it at the time of use.

In order to put the insect repellent 1 into use in the present embodiment having the above-mentioned constitution, first the insect repellent 1 is taken out from the hermetically-sealed outer bag (not shown), and then the cover body is removed, and then the clothes. Is attached and fixed to the inner peripheral wall 8a of the transparent or translucent storage container 8 in which is stored. The liquid insect repellent agent 4 impregnated in the substrate 2a is gasified and volatilized from the surface of the substrate 2a, passes through the nonwoven fabric 3a, and is diffused into the storage container 8.

When the substrate 2a is impregnated with the liquid insect repellent 4, the liquid insect repellent 4 in the substrate 2a continues to move to the surface, and the volatilization ends at the end, but when the volatilization ends, the concealment is concealed. Since the liquid insect repellent agent 4 that has penetrated into the layer 2c is not present, the hiding layer 2c becomes opaque.

That is, during the period of use of the insect repellent 1, the hiding layer 2c changes from a transparent state to an opaque state. This change is visually observed from the outside of the storage container 8 through the transparent plastic film 3b and the storage container 8. Since it can be done, it is necessary to purposely check the insecticide 1
This eliminates the trouble of removing the reed from the storage container 8 and eliminates the problem of delaying the replacement time of the insect repellent 1.

Further, since the insect repellent 1 is fixed to the inner wall surface 8a of the storage container 8 by the adhesive seal 7, when there are many items to be stored, the insect repellent 1 may be scattered between the items to be stored.
There is also no problem that the insect repellent 1 will fall to the bottom of the storage container 8 when there are few stored items.

Next, another embodiment will be described. That is, FIG. 2 shows a second embodiment of the present invention, which is the same as the first embodiment except that the concealing layer 2c is cut out intermittently. The part that is hollowed out is the colored surface 2 of the lower layer
Since b is exposed, the colored surface 2b of the hollowed-out portion will be exposed again when the liquid insect repellent 4 is completely vaporized. Therefore, if the colors of the colored surface 2b and the concealing layer 2c are combined in a strong contrast, for example,
When the word "End" is hollowed out, the character appears to be raised, and it is possible to more clearly inform the end time of the drug effect. (See Figure 3)

In the first and second embodiments, the base 2
Although the case where the surface of a is colored to be the colored surface 2b has been described, the present invention is not limited to this. For example, a coloring material such as a pre-colored nonwoven fabric or paper is attached to the surface of the substrate 2b. It may be one, in short,
It suffices that the hiding layer 2c has a contrast with the color in the opaque state.

FIG. 4 shows a third embodiment of the present invention, which is the second embodiment except that an opening 9 is provided at the peripheral end of the packaging material 3.
It is similar to the embodiment. The insect repellent 1 may be discarded together with the packaging material 3 when the liquid insect repellent 4 is completely evaporated, but it is reasonable in terms of cost if only the carrier 2 is replaced with the packaging material 3 left. This embodiment achieves this, and the opening 9 serves as an entrance and exit when the carrier 2 is replaced, and the carrier 2 is enclosed in the packaging material 5 through the opening 9.

In the first, second and third embodiments, the case where the plastic film 3b is entirely transparent has been described, but the present invention is not necessarily limited to this, and a part is opaque. May be used, in short, the hiding layer 2c may be visually observed through the plastic film 3b.

Further, in the first, second and third embodiments, the packaging material 3 is composed of the non-woven fabric 3a and the transparent plastic film 3b, and the non-woven fabric 3a is formed of a non-woven fabric sheet into a shallow dish shape by a pressing machine. Although the combination of the formed ones has been described, the present invention is not necessarily limited to this. For example, the thick transparent plastic film 3 is used.
It is also possible to use a combination of b formed in a shallow dish shape and the non-woven fabric 3a having a flat shape, or a flat shape, that is, a simple bag shape.

[0026]

According to the present invention, a carrier having a flat plate shape and having a concealing layer on at least one surface impregnated with a liquid insect repellent agent is transparent or semi-permeable with a nonwoven fabric permeable to the agent. Since a packaging material comprising a plastic film or sheet having a transparent portion, the concealing layer is encapsulated so as to face the plastic film or sheet, the insect repellent according to the present invention is transparent or semi-transparent. When installed in a storage container such as a transparent clothing case, the end of drug effect of the insect repellent can be visually judged from the outside of the storage container, saving the troublesome effort of opening the storage container. Moreover, there is a remarkable effect that the replacement time is not overlooked.
