Description

[Detailed Description of the Invention] The present invention relates to an adhesive sheet for capturing harmful animals such as cockroaches, ants, and rats.

Conventionally, when it comes to capturing harmful animals such as cockroaches, ants, and rats, methods have been used in which adhesive substances are applied to paper, etc., or adhesive substances are applied to paper, etc. in advance, and the release paper is removed before use. is proposed. However, the former requires the application of an adhesive substance each time it is used, making the application process cumbersome, while the latter requires expensive release paper to be placed over the entire surface of the adhesive, making it more expensive and economically disadvantageous. It is.

The purpose of this invention is to prevent the adhesive materials from coming into contact with each other without using release paper, and to easily open, close, or tear off sheets coated with adhesive materials, even if they are folded or stacked with the adhesive coated side facing inside. An object of the present invention is to provide an adhesive sheet for trapping harmful animals.

This invention will be described in detail below based on embodiments illustrated in the drawings.

FIG. 1 shows an example of an adhesive sheet folded in two, FIG. 2 shows an example of an adhesive sheet folded into three, and FIG. 3 shows an example of an adhesive sheet folded in a stack.

In FIGS. 1 to 3, reference numeral 1 denotes a rectangular substrate, which is made of a relatively inflexible material such as a sheet or plate made of cardboard, cardboard, plastic, wood, metal, or the like. When the substrate 1 is made of cardboard, one having a thickness of 0.3 mm or more can preferably be used, and paperboard or boards recycled from waste paper can also be used economically.
Furthermore, when the material is a plastic sheet such as polyethylene or polypropylene, it is preferably 0.5 mm or more in thickness, and when it is an aluminum plate, it is preferably 0.2 mm or more in thickness. In addition, if necessary, use of paper and plastic film laminates, composites of paper and plastic sheets, or paper and cardboard that have been treated with water-resistance such as wax can be used to achieve reinforcing effects or adhesives as described below. It can prevent substances from seeping into the paper.

Reference numeral 2 denotes an adhesive substance applied to one side of the substrate 1, and any type of adhesive substance can be used as long as it is adhesive at room temperature, non-drying, and non-flowable at room temperature. This type of adhesive substance is
For example, natural rubber, synthetic rubber, ethylene-vinyl acetate copolymer, polyisobutylene, polybutene,
Atactic polypropylene and other liquid polymers, tackifying resins such as petroleum resins, etc. are mixed alone or in the presence of an appropriate solvent or without a solvent by heating or in the form of a latex or emulsion;
It can be applied and used. In particular, combinations of styrene-butadiene block polymers and/or ethylene-vinyl acetate copolymers, tackifying resins, and plasticizers, and combinations of polyisobutylene, liquid polybutene, and atactic polypropylene can be heated and mixed in a solvent-free system, and can be mixed as is. It is preferable not only in terms of adhesive properties such as being able to be applied, but also in terms of workability.

3 is a spacer, which has a top/bottom area ratio of less than 1, preferably 0.8 to 0.01, in order to differentiate the adhesive strength of the adhesive substance to the top and bottom surfaces of the spacer. Examples of such a spacer 3 include, as shown in FIG. ) with a flange formed at the bottom of the member C,
A pyramid-shaped object such as a triangular pyramid (or square pyramid) D,
A truncated pyramid shape such as a truncated triangular pyramid (or a truncated square pyramid) E, a T-shaped cross section F, a cup-shaped shape G, a through hole formed along the central axis of the truncated cone (or truncated pyramid) H etc. can be used,
In either case, it is preferable that the bottom surface is flat.
The spacer 3 in Figures 1 to 3 is the same as Figure 4B.
This is the spacer shown in . The height of the spacer is preferably matched to the width of the folded portion 5. The spacer can be made of paper, plastic, foamed polyethylene, foamed styrene, metal, etc., as appropriate, and if necessary, the spacer should be treated with a non-adhesive treatment such as coating or impregnating the top surface with silicone oil. Good too.

In the double-fold type adhesive sheet shown in FIG. 1, a folding line 6 is provided in advance at the center of the substrate 1 in order to provide a folded portion 5. As shown in FIG. The bent portion 5
Although the width depends on the coating thickness of the adhesive substance, it is preferably about 3 to 15 mm, preferably about 5 to 10 mm. Next, an adhesive substance 2 is applied to the substrate 1 while leaving a margin 4 of a certain width on the outer peripheral edge (vertical edge and horizontal edge) of the substrate 1.
This can be obtained by forming an adhesive substance-coated surface in the center of the adhesive substance-coated surface, and then adhering one or more spacers 3 to the center of the right or left half of the adhesive substance-coated surface. When adhering the spacer 3 to the surface coated with the adhesive substance, the bottom surface of the spacer 3 may be bonded to the surface coated with the adhesive substance. If you do this, Figure 1B
In the folded state as shown in FIG.
It can be easily opened as shown. Furthermore, since the ratio of the top surface to the bottom surface of the spacer 3 is less than 1, it is possible to easily open the state from the state shown in FIG. 1A to the state shown in FIG. 1B.
The adhesive material attached to the top of the board is unlikely to extend like a string.The three-fold type adhesive sheet shown in FIG. 6' is provided. The width of the folded portions 5, 5' may be the same as that of the double-folded adhesive sheet shown in FIG. Next, the adhesive substance 2 is applied to the substrate 1 in the same manner as shown in FIG. 1 to form an adhesive substance coated surface, and a plurality of spacers 3 are adhered onto the coated surface. This adhesive sheet also prevents the adhesive materials from coming into contact with each other by the spacer 3 in the folded state as shown in FIG. 2B, and can be easily opened again as shown in FIG. 2A.

The two-ply type adhesive sheet shown in FIG. 3 does not require a folded portion, and this sheet is made by applying an adhesive substance 2 to a substrate 1 in the same manner as shown in FIG. It can be obtained by gluing. In this case, as shown in FIG. 3B, two adhesive sheets 1 and 1' can be placed one on top of the other with their adhesive surfaces facing each other,
It is also possible to overlap the adhesive material surface of one adhesive sheet 1 and the back surface of the other adhesive sheet 1' facing each other.
The spacer 3 prevents the adhesive substances of the two sheets from coming into contact with each other, or the adhesive substance of one sheet 1 and the back surface of the other sheet 1', and both sheets can be easily separated again to the state shown in FIG. 3A. be able to.

Note that a folded portion having a predetermined width may be formed on the outer peripheral edge of the substrate 1, or this folded portion may be used as the margin 4.

As described above, in the present invention, since a spacer with a top/bottom area ratio of less than 1 is adhered to the surface coated with the adhesive material, it is possible to prevent the surfaces of the adhesive material from coming into contact with each other without using expensive release paper. Since there is a difference in the adhesion strength to the adhesive material on the top and bottom of the spacer, the adhesive sheet can be easily opened, closed, or peeled off when used.
