BACKGROUND OF THE INVENTION
The present invention relates to a cockroach trap and a method for producing the same. More specifically, a cockroach trap using an adhesive, which can reliably prevent escape to the outside of the trap by effectively interfering with the walking of the cockroach that has entered the trap, and It relates to the manufacturing method.
[0002]
[Prior art]
Various types of sticky cockroach traps have been known in the past, and as a general cockroach trap, an adhesive is applied to the entire surface of the flat bottom of the hollow cockroach trap body, or There is one in which an adhesive portion is formed by painting a plurality of lines in parallel. In addition, there is also a cockroach trap in which an adhesive portion is formed by applying a pressure-sensitive adhesive in a wavy streak form to improve capture efficiency with a small amount of adhesive (Japanese Utility Model Publication No. 53-29975).
[0003]
As another example of the catcher, Japanese Utility Model Publication No. 53-1000048 discloses a catcher formed by bending a plate having a concavo-convex shape in a straight line so that a concave portion and a convex portion are inside. . Such a trap does not have a bottom plate and is formed by using a plate to form an arched tunnel. Therefore, there is no problem that cockroaches do not intrude due to a difference in feeling with the floor surface of the room and a difference in feeling with respect to a step at the entrance of the trap. Cockroaches entering the trap are captured by the adhesive layer inside the plate sticking to the back of the cockroach.
[0004]
[Problems to be solved by the invention]
However, in the trap with the adhesive applied to the top of the flat bottom of the trap body, if the cockroach that has entered the trap is wet with water, oil, etc., the viscosity of the adhesive will weaken and escape. There is. In particular, traps with adhesive strips applied in parallel or with a wavy streak described in Japanese Utility Model Laid-Open No. 53-29975 have entered the trap because the non-adhesive portion remains on the top of the bottom. It is not enough to prevent the escape of cockroaches.
[0005]
In addition, the trap having an uneven portion on the adhesive portion described in Japanese Utility Model Publication No. 53-100322 is insufficient for preventing the escape of cockroaches because the uneven portion is a linear repetition. Also, since this trap does not have a bottom plate, if a cockroach enters the vicinity of the center of the trap, the back of the cockroach passes through the trap without sticking to the adhesive part, which is insufficient for preventing escape. .
[0006]
Furthermore, even if the uneven portion is formed on the adhesive portion, if it is stored or transported as it is, there is a problem that the adhesive portion gradually falls due to temperature or its own weight and the uneven portion is likely to become flat.
[0007]
The present invention has been made in order to solve such a problem, and is a cockroach trap using an adhesive, and effectively prevents walking of a cockroach that has entered inside the trap. An object of the present invention is to provide a cockroach catcher that can reliably prevent escape.
[0008]
Another object of the present invention is to provide a cockroach trap with release paper that can exhibit the effect of preventing the escape of cockroaches and a method for producing the same.
[0009]
[Means for Solving the Problems]
The cockroach trap of the present invention is a cockroach trap that consists of a trap body having at least a bottom portion and has an adhesive portion on the upper surface of the bottom portion,
A plurality of protrusions are arranged in the adhesive portion, and at least a part of the protrusions is bent in a horizontal direction.
[0010]
The protrusions are preferably meandered continuously in the horizontal direction along the axial direction of the trap body.
[0011]
It is preferable that the protrusion is meandering continuously in the horizontal direction along the width direction of the trap body.
[0012]
The protrusion is formed by combining a portion meandering in the horizontal direction along the axial direction of the trap body and a portion meandering in the horizontal direction along the width direction of the trap body. Is preferred.
[0013]
It is preferable that the ridges meander in the horizontal direction along the diagonal direction of the trap body.
[0014]
It is preferable that the protrusions have a substantially wedge shape, the protrusions are formed in a staggered manner, and the protrusions in adjacent rows are opposite to each other.
[0015]
It is preferable that each of the protrusions has a width of about 2 to 20 mm.
[0016]
The cockroach trap according to claim 2, comprising a trap body having at least a bottom portion, and having a sticking portion on an upper surface of the bottom portion,
A plurality of protrusions are arranged in a staggered pattern on the adhesive portion.
[0017]
The cockroach trap according to claim 3 is a cockroach trap comprising a trap body having at least a bottom portion and an adhesive portion on an upper surface of the bottom portion, and a release paper for covering the adhesive portion,
A plurality of protrusions are arranged on both the adhesive part and the release paper, and at least a part of the protrusions is bent in the horizontal direction.
[0018]
The method for producing a cockroach trap according to claim 5 is: (a) forming an adhesive portion on the upper surface of the bottom portion of the trap body;
(B) The adhesive portion is covered with release paper, and (c) a protrusion that is bent at least partially in the horizontal direction is arranged on both the adhesive portion and release paper.
[0019]
In the cockroach trap and the manufacturing method thereof (Claim 5) according to claim 1, the viscosity of the adhesive substance applied to the adhesive part is preferably about 2500 to 3300 P around 130 ° C.
[0020]
In addition, meandering in this specification is not linear, and the degree of the curved portion (such as curvature or length) is not particularly limited and may not be regular.
[0021]
As a result of intensive studies on means for making it difficult for a cockroach that has entered the cockroach trap to walk on the adhesive portion, the present inventors have come up with the present invention.
[0022]
That is, according to the first aspect of the present invention, a plurality of protrusions are arranged in the adhesive portion, and at least a part of the protrusions are bent in the horizontal direction by meandering. Even if cockroaches with wet feet intrude into the trap, even if the viscosity of the adhesive part decreases, the feet get caught on the ridge and it becomes difficult to walk, so it is possible to prevent the escape of cockroaches reliably .
[0023]
According to the invention described in claim 2, since the plurality of protrusions are formed in a staggered pattern on the adhesive portion, when a cockroach or the like whose feet are wet with water or oil enters the trap. Even if the viscosity of the adhesive part decreases, the foot gets caught on the protrusion and it becomes difficult to walk, so that the escape of cockroaches can be surely prevented.
[0024]
Furthermore, according to the third and fifth aspects of the invention, by arranging the protrusions on both the adhesive portion and the release paper, there is no problem that the unevenness of the adhesive portion becomes flat. In this case, the same effect of preventing the escape of cockroaches as in the first aspect of the present invention can be obtained. Furthermore, by setting the viscosity of the adhesive substance applied to the adhesive part to 2500 to 3300 P around 130 ° C., the ridge is maintained even after the release paper is peeled off, and the ridge is not broken during use.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Next, the cockroach trap of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an embodiment of the cockroach trap of the present invention, FIG. 2 is a sectional view taken along line II-II of the cockroach trap of FIG. 1, and FIG. 3 is a development of the cockroach trap of FIG. FIG. 4 is a plan view showing a developed state of a cockroach catcher according to another embodiment of the present invention, and FIGS. 5 to 7 are other views of the cockroach catcher according to the present invention. It is a top view which shows the state which expand | deployed the cockroach trap which shows an Example.
[0026]
The cockroach trap shown in FIGS. 1 to 3 is provided with an adhesive portion 2 formed in an uneven shape that is meandered over substantially the entire upper surface of the bottom portion 3 of a normal separable trap body 1 that has been conventionally employed. Cockroaches through the openings 4a and 4b opened in the axial direction of the trap body 1 and the openings 6a and 6b formed in the side portions 5a and 5b on both sides of the trap body 1 Can enter the inside of the trap body 1.
[0027]
The trap body 1 is a sheet made by combining paper, plastics, rubber, metal, wood, etc., alone or in combination, and folded in the manner of origami work (the one-dot chain line in FIG. 3 is valley-folded and the broken line is mountain-folded). It is formed so that it may become a hollow body by connecting two top plate 7a, 7b.
[0028]
In addition, in the present embodiment, the trap body having a flat trapezoidal cross section has been described as an example, but the shape of the trap body 1 is not particularly limited in the present invention. An inverted trapezoidal shape, a rectangular shape, a triangular shape or a polygonal shape, a semicircular shape, a square shape, a cylindrical shape, a box shape, or the like can also be employed.
[0029]
The adhesive part 2 has a plurality of protrusions 9 and grooves 10 that meander continuously by applying a process such as embossing, pressing with a concavo-convex die or a grooved roller to the bottom 3 of the trap body 1. Are alternately formed, and an adhesive substance is applied to the entire top surface of the bottom 3. The adhesive portion 2 is protected by a release paper 15 (see FIG. 3) during storage and transportation, and the adhesive portion 2 is exposed by peeling the release paper immediately before use, and becomes ready for use. Between the protrusion 9 and the protrusion 9, the groove | channel 10 which is horizontal, ie, the bottom is flat, is preferable.
[0030]
The pressure-sensitive adhesive material applied to the bottom 3 may be any non-drying material that is sticky at room temperature and non-flowable at room temperature, and usually comprises a softener and a tackifying resin. As the softening agent, for example, polybutene, mineral oil, lanolin, liquid polyacrylate, etc. can be used. As the tackifying resin, petroleum resin, rosin, hydrogenated rosin, hydrogenated rosin ester, terpene hydrocarbon resin, aliphatic hydrocarbon resin, alicyclic hydrocarbon resin, aromatic hydrocarbon resin, phenol resin, etc. can be used. .
[0031]
Rubber can also be added to increase tackiness and strength. As rubber, natural rubber and synthetic rubber such as butyl rubber, polyisobutyl rubber and chlorobrene rubber can be used.
[0032]
In the production of the adhesive substance, for example, when rubber is added, it may be previously dissolved in a solvent such as toluene or n-hexane and then added to the tackifier resin and the softener. Further, rubber, tackifying resin and softening agent may be blended and dissolved in a solvent such as toluene. At this time, if there is an excess solvent, it may be removed. In addition, when the raw material used has favorable compatibility, it can manufacture without using a solvent.
[0033]
The viscosity of the pressure-sensitive adhesive produced from the above materials and applied to the bottom 3 is measured by a measuring method according to JIS K6833 (1980), and is preferably in the range of about 2500 to 3300 P around 130 ° C. As an effect thereof, the shape of the ridge 9 is maintained even after the release paper is peeled off, and the shape of the ridge 9 is not lost during use.
[0034]
1-3, the protrusion 9 and the groove 10 are formed along the axial direction of the trap body 1. Thus, even if the cockroach or the like whose feet are wet with water or oil enters the trap through the openings 4a and 4b and the openings 6a and 6b, Since it catches on the protrusion 9 and the groove 10 and effectively blocks walking, the escape of cockroaches can be reliably prevented. In particular, since the protrusions 9 and the grooves 10 are formed along the axial direction of the trap body 1, the trap body 1 can be more effectively prevented from entering the width direction and escaping in the width direction. Can interfere with walking.
[0035]
Moreover, as for the adhesion part 2, the protrusion 9 and the groove | channel 10 may be formed along the width direction of the said trap body 1 as FIG. 4 shows. In this case as well, the legs get caught on the ridges 9 and the grooves 10 and effectively hinder walking, so that the escape of cockroaches can be reliably prevented. In particular, since the protrusions 9 and the grooves 10 are formed along the width direction of the trap body 1, the effect can be more effectively prevented against intrusion from the axial direction and escape in the axial direction. it can.
[0036]
Further, as shown in FIGS. 5 to 6, the adhesive portion 2 is a combination of portions 9 a and 10 a where the protrusions 9 and the grooves 10 are along the axial direction of the trap body 1 and portions 9 b and 10 b along the width direction. May be formed. In the adhesion part 2 of FIG. 5, the protrusion 9 and the groove | channel 10 along an axial direction and the width direction are arrange | positioned intermittently. In addition, you may form the linear protrusion 14 in the area | region where the adhesion part 2 is vacant. On the other hand, in FIG. 6, the protrusions 9 and the grooves 10 are continuously arranged in a loop shape. In these cases of FIGS. 5 to 6, walking can be effectively prevented against intrusion and escape from both the axial direction and the width direction.
[0037]
Although not shown in the drawings, if the protrusion 9 and the groove 10 are formed along the diagonal direction of the trap body 1, there is an entry opening at the corner portion of the trap body 1. Even can effectively prevent walking.
[0038]
In the present embodiment, as shown in FIG. 2, only the portion of the protrusion 9 is protruded upward in the bottom portion 3, and a portion relatively lower than the protrusion 9 between the adjacent two protrusions 9 is formed. It is used as the groove 10. However, the present invention is not limited to this, and only the portion of the groove 10 may be protruded downward, or the protrusion 9 and the groove 10 may be formed by performing continuous corrugation.
[0039]
If the ridge 9 and the groove 10 are too wide or too small, the legs of the cockroach will not catch on the ridge 9 and the groove 10 and will not be able to effectively interfere with walking. It is preferable that the width is set to about 4 to 8 mm.
[0040]
In the present embodiment, the ridge 9 and the groove 10 meander and are described. However, the present invention is not limited to this, and the adhesive portion 2 has a plurality of ridges 9 and grooves. If 10 are alternately formed and at least a part of the ridge 9 and the groove 10 is bent in the horizontal direction, the legs of the cockroach are caught on the ridge 9 and the groove 10 and effectively prevent walking. Can do. Therefore, in addition to the meandering type, the above-described effect can be obtained even when the adhesive portion 2 is provided with a plurality of concentric or sawtooth-shaped protrusions 9 and grooves 10.
[0041]
In the examples of FIGS. 3 to 6 described above, examples in which the protrusions 9 are continuously arranged are shown, but the present invention is not limited to this. In short, a plurality of protrusions 9 need only be arranged, and may be intermittent rather than continuous.
[0042]
For example, as shown in FIG. 7, the ridges 9 have a substantially wedge shape, the ridges 9 are formed in a staggered pattern, and the ridges 9 in adjacent rows are opposite to each other. May be directed. In this case, a gap between adjacent ridges 9 serves as the groove 10. In the case of FIG. 7, the cockroach escape preventing effect can be obtained.
[0043]
Further, in place of the substantially wedge-shaped protrusion 9 in FIG. 7, a plurality of protrusions having a round shape, a triangular shape, a quadrangular shape or other polygonal shapes, or a rod shape, a saddle shape, an X shape, a star shape or the like are staggered. They may be arranged in a shape. In this case as well, the gap between adjacent protrusions serves as the groove 10. Therefore, the effect of preventing the escape of cockroaches can be achieved.
[0044]
Moreover, you may coat | cover the adhesive part 2 of FIGS. 1-7 with the release paper 15 (refer FIG. 3) for the protection at the time of transport and storage. In this case, after covering the adhesive portion 2 with the release paper 15, the ridges 9 and the grooves 10 (or the wedge-shaped ridges or projections in a staggered arrangement) are simultaneously formed on both the adhesive portion 2 and the release paper 15. By doing so, the adhesive is kept in a predetermined shape, and the problem that the unevenness of the adhesive portion 2 becomes flat is eliminated. Therefore, if the release paper 15 is peeled off and used, the effect of preventing the escape of cockroaches can be obtained.
[0045]
When the size of the trap body 1 is too large, the usability is deteriorated and the manufacturing cost is increased. Therefore, it is preferable to set the width to 50 cm or less and the length to about 50 cm or less.
[0046]
Further, in order to make it easier for cockroaches to easily enter and to escape, the treads 8 are formed at the openings 4a and 4b that are opened forward and backward in the axial direction of the trap body 1 higher than the bottom portion. Also good.
[0047]
Further, as shown in FIGS. 1 to 3, the trap body 1 selects and inserts the insertion piece 11 provided on the top plate 7 a into the insertion port 12 provided on the other top plate 7 b in the state of use. Thus, the height from the bottom 3 to the top plates 7a and 7b can be adjusted. In addition, 13 is a pressing piece, and by sandwiching a part of the other top plate 7b together with the insertion piece 11, the coupling between the top plates 7a and 7b is made more rigid. In addition, if the height of the top plates 7a and 7b is set to the lowest level, the cockroach trap can be inserted and installed in a slight gap such as between the floor and furniture.
[0048]
Here, an experiment was conducted to numerically grasp the effect of cockroach escape prevention. The results are shown in Table 1. Table 1 shows one immature small cockroach (young in Table 1), medium maturity (size) cockroach (in Table 1), and one large mature cockroach (in Table 1). The average number of steps when the number of steps taken in the cockroach catcher and 20 steps on the adhesive part is measured is summarized. The compared cockroach trap is a cockroach trap ((1) in Table 1) having a stick and a groove formed along the axial direction of the trap body as shown in FIG. 3, as shown in FIG. And a cockroach trap (Table 2 in Table 1) having a sticky portion having protrusions and grooves formed along the width direction of the trap body, and a conventional cockroach trap (Table 1) having a flat sticky portion. (3)). From Table 1, it can be seen that (1) and (2), which are examples of the present invention, are both young, medium and mature, and the number of steps is greatly reduced compared to (3) which is a conventional example. .
[0049]
[Table 1]

[0050]
From the results of Table 1 above and the observation of the behavior of cockroaches during the experiment, since the ridges and grooves are not linear, a relatively large cockroach tries to escape from the adhesive portion and quickly moves on the top of the ridges. When walking in a straight line, it was found that there was a high possibility that the foot would be stepped off from the ridge, and the foot and torso would stick to the adhesive part. On the other hand, small cockroaches tried to walk along the groove, but since the groove was not linear, there was a high possibility of hitting the ridge, and it was found that the foot and the torso were likely to stick to the adhesive part. Thus, it was found that cockroaches of all sizes can be effectively and effectively prevented from escaping to prevent escape.
[0051]
【The invention's effect】
According to the present invention, even if a cockroach or the like whose feet are wet with water or oil enters the trap, even if the viscosity of the adhesive portion decreases, the feet get caught in the ridges and grooves and walk effectively. Because it interferes, the escape of cockroaches can be reliably prevented.
[0052]
Moreover, after covering the adhesive portion with the release paper, forming the protrusions and grooves as necessary on both the adhesive portion and the release paper eliminates the problem that the unevenness of the adhesive portion becomes flat. Therefore, if the release paper is peeled and used, the effect of preventing the escape of cockroaches can be obtained.
[0053]
Furthermore, by setting the viscosity of the adhesive substance applied to the adhesive part to 2500 to 3300 P around 130 ° C., the ridge is maintained even after the release paper is peeled off, and the ridge is not broken during use.
