Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pressure-sensitive adhesive sheet for trapping pests, such as cockroaches, to which pests can be trapped using an adhesive, and a method for producing the same.

Conventional sheets of this type are generally just cardboard coated with adhesive, and the front and rear ends are open.
The sheet was attached to the bottom of the box, and the tips of the legs of cockroaches, etc. that entered the box through the opening were attached to the adhesive surface of the sheet to capture them.

Further, as a conventional example having characteristics in the sheet itself, there is known a sheet described in Japanese Utility Model Publication No. 52-18941. This is done by providing a large number of fold lines on the surface of a sheet made of cardboard or the like, folding it into a bellows shape, applying a trapping adhesive to the surface of each trough, and applying a spill stopper to each end. The sheet is folded into a folded shape, and a release paper is temporarily attached to the top of the sheet, which is folded into a bellows shape.When in use, the folded part is pulled left and right to form a flat sheet. It is something that expands to . Therefore, when a cockroach is caught, the tips of its legs are attached to a flat sticky surface.
This is the same as the conventional general example. In addition, in order to ensure the capture of cockroaches, etc., there are devices in which treads of various shapes are provided on both ends of the adhesive sheet facing the entrance of the box, but these also have the adhesive surface of the adhesive sheet. is flat, and the tips of the legs of cockroaches and the like can be attached to and captured using this flat adhesive surface. In this way, conventional adhesive sheets are designed to attach to the tips of the feet of cockroaches, etc., so if the feet of cockroaches etc. are dirty with oil (most cockroaches living in the kitchen have oily feet) Cockroaches often escape by cutting off the tips of their legs, and large cockroaches sometimes escape by cutting off the tips of their legs. Furthermore, when the adhesive deteriorates over time, the capture ability becomes significantly inferior. Furthermore, when the adhesive sheet itself is formed into a special shape, for example,
The product described in Japanese Patent Publication No. 18941 is more difficult to manufacture than a general pressure-sensitive adhesive sheet, and there is a risk that the manufacturing cost will eventually increase. SUMMARY OF THE INVENTION An object of the present invention is to provide a pressure-sensitive adhesive sheet for trapping pests that eliminates the above-mentioned conventional drawbacks and has significantly improved trapping ability, and also to provide a method for manufacturing this pressure-sensitive adhesive sheet easily and inexpensively. be.

Preferred embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an unused adhesive sheet according to the first embodiment. , and the surface coated with this adhesive 3 (adhesive surface 3
A plurality of cuts 4 are formed in the region a).

The notches 4 are formed in a plurality of rows in a direction perpendicular to the longitudinal direction of the adhesive sheet, and the individual notches in both adjacent rows are arranged at alternate positions. Locking holes 5 are formed at both ends of the base material 2. This locking hole 5 is inserted into the adhesive surface 3 by pulling both ends of the adhesive sheet.
When the part a is extended, it is attached to the locking pieces 8 formed on both edges 7 of the main body 6 as a means for attaching it to the box-shaped main body 6 which has a large opening □ on the top surface shown in FIG. It is something that makes it stop. That is, by inserting the locking piece 8 into the locking hole 5, the adhesive surface 3a of the adhesive sheet 1 is fixed to the main body 6 in a longitudinally extended state. The combination of these locking holes 5 and locking pieces 8 is an example of a means for attaching the adhesive sheet 1 to the main body 6.
Double-sided adhesive tape (not shown) may be pasted on both edges 7 of the tape, and both ends of the adhesive sheet may be pasted on the top surface of this tape, and it is of course possible to adopt other appropriate means. . The main body 6 shown in FIG. 3 has both edges 7 to which both longitudinal ends of the adhesive sheet 1 are attached formed above the bottom part 9. In other words, the adhesive sheet 1 is attached to the main body 6 so as to provide a gap on the lower surface thereof. Moreover, it has a roof part 10 that covers the adhesive sheet in parentheses so that a gate part is formed on both ends of the adhesive sheet in the longitudinal direction. When the adhesive sheet 1 formed in the positions where each row is parallel to each other and the individual notches 4 of both adjacent rows are mutually conveyed is attached to the main body 6 with its adhesive surface 3a extended, As shown in FIGS. 4 and 5, the cut 4 expands to form a hole 4a, and the whole is deformed into a continuous uneven shape undulating vertically and horizontally. FIG. 6 shows an unused adhesive sheet according to the second embodiment of the present invention, in which diagonal cuts 4 in different directions are formed to form a continuous diamond-shaped pattern, and two diamonds are formed in each diamond shape. Cuts 4 are formed parallel to each other in a direction perpendicular to the pulling direction.

When using this adhesive sheet 1, make cuts 4 in a total of three directions, one perpendicular to the pulling direction and two diagonal directions.
When the adhesive surface 3a is stretched by pulling both ends in the longitudinal direction, the whole can be formed into a continuous uneven shape with complicated waves as shown in FIGS. 7 and 8. , the notch can expand to form the hole 4a. FIG. 9 shows an unused adhesive sheet 1 according to the third embodiment of the present invention, in which the shape of each unit of the notches 4 is made into a dogleg shape, and the overall arrangement is the same as that of the first embodiment. Similarly, they are formed alternately.

When the notches 4 of the adhesive sheet 1 are formed in the holes 4a along the ship's side, the tongue pieces 11 are randomly oriented such that they face upward or downward, or either upward or downward depending on the location, as shown in FIG. 10a or b. Form. In the first to third embodiments described above, the arrangement of the notches 4 and the shape of the notches 4 themselves are respectively changed, and due to these changes in the arrangement and shape, the length of the adhesive sheet 1 is adjusted during use. This is to change the uneven shape of the adhesive sheet 1 (a state in which both ends of the adhesive sheet 1 are pulled and the notches 4 are connected to each other).

Therefore, depending on how the cuts 4 are formed, the unevenness of the adhesive sheet can be made into any shape.
In the present invention, the arrangement and shape of the cuts 4 may be any arrangement and shape as long as the adhesive sheet 1 is formed into a continuous uneven shape during use. be. Further, the main body 6 to which such an adhesive sheet 1 is attached may be of the type shown in FIG. 11 in addition to the one shown in FIG. 3.

A characteristic feature of this main body 6 is that a valley fold line a is inserted between both ends of the mounting member 12 to which the adhesive sheet 1 is directly attached at the boundary with the base 13. 3 mountain fold lines b, c, d at the specified intervals.
, and fold the respective fold lines a to d to form the rising part 14, the sticking part 15, the lid part 16, and the insertion part 17.
was formed. Then, attach both ends of an unused adhesive sheet to the adhesive part 15, and then pull the insertion part 17 (in the direction of the arrow in FIG. 12) to raise the rising part 14. Box stand 18
Insert and secure it into the insertion port 19 (see Fig. 13). The trap thus assembled is installed on the bottom part 9 of a structure in which the roof part 10 and the bottom part 9 are integrally formed, thereby completing the trap. Note that the structure of the main body 6 is of course not limited to that shown in FIGS. However, this is an example of how the pressure-sensitive adhesive sheet of the present invention is used, and does not limit the method of use. Next, an example of a method for manufacturing the pressure-sensitive adhesive sheet 1 constructed as described above will be described with reference to FIG. 14.

First, the base material 2 is sent out from the supply roller 20, a plurality of cuts 4 are formed in the base material 2 by the cut roll 21 on the way, and the adhesive application nozzle 2 is applied onto the base material 2 where the cuts 4 are formed.
2, the adhesive 3 is applied, the adhesive 3 coated Motomura 2 is cooled by passing through a cooling roll 23, and then a release paper 24 is attached to the adhesive surface 3a, and finally it is cut into a predetermined size. By cutting with the cutter 25, the adhesive sheet 1 with the adhesive surface 3a protected by the release paper 24 is manufactured. Depending on the shape or arrangement of the blades of the cutting roll 21, various shapes or arrangements of the cuts 4 are formed. Further, the notch 4 may be formed after the adhesive 3 is applied. When the cut 4 is formed before applying the adhesive 3 as in the illustrated embodiment, when the cut 4 is expanded, the portion of the adhesive 3 corresponding to the cut 4 also has the cut 4.
With the expansion of the hole 4a, the adhesive 3 spreads as if splitting, and in some cases, the adhesive 3 is present in a thread-like manner so that a spider's web is formed at the expanded hole 4a. If the threads of the adhesive 3 are present in the holes 4a in this manner, the threads will become entangled with the legs of pests, making it even more difficult for the pests to escape. Next, how the adhesive sheet 1 of the present invention captures pests, such as cockroaches, will be explained. Since it is formed in an uneven shape, a cockroach that has been attracted to the adhesive surface 3a can drop its foot into the hole 4a or step into the recess, causing the adhesive 3 to be attached to the base of the foot, body, or wing. The adhesive 3 will adhere to the area other than the tip of the foot to the extent that the person struggles to escape.

In particular, since the base material 2 is flexible, as the cockroach struggles to escape, the convex part becomes depressed or the concave part rises, or the tongue piece 11 attached to the body of the cockroach follows the movement of the cockroach. It flutters around and does not move away easily, making it difficult for cockroaches to escape. Furthermore, if the adhesive 3 is drawn in a plurality of threads through the hole 4a, the threads become entangled with cockroaches, making it even more difficult for them to escape. As explained above,
The adhesive sheet for trapping pests of the present invention includes applying an adhesive to a movable substrate, forming a plurality of incisions in the area where the adhesive is applied, and expanding the incisions to form holes. By pulling both ends of the Motomura to form a continuous uneven shape, it is possible to not only attach the tips of cockroaches' legs like a flat adhesive sheet, but also make it easier for cockroaches etc. to stick their legs into holes or recesses. By letting the cockroach step on it, the base of its foot and the same part of the cockroach will stick to it, and when it struggles to escape, the uneven shape of the visible and sexual base material will change, making the adhesive stick even more closely to the cockroach's body, making it difficult for them to escape. Once you get used to it, you can catch it reliably.

In addition, when a cut is made only in the base material, and when the cut expands to form a hole, the adhesive pulls multiple threads into the hole, and the threads are attracted to cockroaches etc. You can catch it more reliably than by entangling it. Further, according to the present invention, a sufficient capturing ability can be maintained even if the adhesive deteriorates to some extent, compared to the adhesive that attaches the tip of the leg of a cockroach or the like. According to the adhesive sheet manufacturing method of the present invention, a plurality of cuts are formed with a cutting roll while the base material is continuously fed out in one direction, and an adhesive is applied after or before the formation of the cuts, Finally, the pressure-sensitive adhesive sheet can be manufactured very easily by cutting it into a predetermined size, and moreover, a large amount of pressure-sensitive adhesive sheets can be continuously manufactured. Furthermore, the equipment is simple, the work is easy, and the produced pressure-sensitive adhesive sheet can be provided at low cost.
