[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for trapping small harmful animals such as rats.

[0002]

2. Description of the Related Art A catcher for capturing a small animal with a sticky substance having a specific adhesive substance coated on the inner surface thereof at a predetermined thickness is placed in a place where a harmful small animal such as a mouse appears and disappears. ing. As this tray, a tray formed by stamping a single sheet of black, matted, heat-resistant polypropylene is often used. When not in use or during transportation, release paper is placed on the adhesive material, and the release paper may be peeled off when used.However, since expensive release paper is used, this increases costs and is economically disadvantageous. It is.

Therefore, a plurality of projections serving as spacers are provided at the center of the tray, and the two trays are arranged so that the projections are in contact with the adhesive substance inside so that the surfaces of the adhesive substance do not come into contact with each other. I thought about doing it. However, when the two trays are separated for use, if the protrusions are in contact with each other, the adhesive substance attached to the tops of the protrusions extends in the form of a thread and is inconvenient. Absent.

In the present invention, in order to solve the above-mentioned drawbacks, "the peripheral bank 1 is provided around the periphery, the adhesive substance 6 is applied inside, and two or more projections 3 are provided at the center of the tray. And the height of the projections 3 is set to be 1 to 4 mm lower than the height of the peripheral bank 1, and the sticky substance 6 is removed by the trap for the trap. When the pressure is applied from the outside, the contact area where the projections come into contact at the top is 5 to 25 mm ² when the pressure is applied from the outside, and when there is no pressure
Is a tray for a harmful animal trap, wherein a gap is formed between the projections. Is obtained.

FIG. 1 is a perspective view of the tray of the present invention, and FIG. 2 is a cross-sectional view taken along the line XX of FIG. 1. The tray 10 has a peripheral bank 1 around its periphery. Is formed. Two or more projections 3 are provided at the center of the tray 10. The height of the protrusion 3 is set to be 1 to 4 mm lower than the height of the peripheral bank 1.

Further, an engagement projection 4 is formed at the center of one side of the peripheral bank portion 1, and an engagement hole 5 into which an engagement projection of another tray fits is formed at a corresponding position on the other side. The tray 10 is formed by, for example, embossing a single thin sheet of plastic such as black matte heat-resistant polypropylene.
The adhesive substance 6 for capturing harmful small animals is applied on the bottom surface 2.

FIG. 3 shows two trays 10, 1 when not in use.
0 'is shown with the adhesive material 6 inside. That is, another tray 10 ′ is stacked on the tray 10 with the surface of the adhesive substance 6 aligned. At this time, the peripheral bank portions 1 and 1 'of the trays 10 and 10' overlap, and the engaging projections 4 of the tray 10
Are fitted into the engaging holes 5 'of the tray 10', and the engaging projections 4 'of the tray 10' are fitted into the engaging holes 5 of the tray 10, so that they are engaged.

In the tray of the present invention, the height of the projections 3 is 1 to 4 mm lower than the height of the peripheral bank 1, so that
When the trays 10 and 10 'are put together, there is a gap of 2 to 8 mm between the projections 3 and 3'. Is prevented from extending in a thread shape. The protrusions 3 and 3 'are provided when the back of the trays 10 and 10' is pressed.
It acts as a spacer so that the surface of the adhesive substance does not contact. The shape of the projection 3 may be any shape such as a pyramid, a cone, a column, and a prism.

Further, the trays 10 and 1 shown in FIG.
When pressure is applied from the outside with the 0's placed with the adhesive substance inside, the tray bends. At this time, the projections 3 and 3 'prevent the projections from coming into contact with each other at the top thereof, preventing the tray from bending further, and preventing the adhesive substances of the trays 10 and 10' from coming into contact with each other. And the pressure is relieved
A gap is formed again between the projections due to the elasticity of the
It is. The tray is not under pressure from outside
When there is a gap between the projections at all times,
Adhesion from upper projection to lower projection due to material flow
The amount of material transmitted is small, and trays 10 and 10 '
When the adhesive is released, the adhesive substance extends in a thread form and the trays 10, 1
It is prevented that it becomes difficult to separate 0 '. or
Even if the adhesive substance may be transmitted when the projections are bonded,
If the touch area is within the range of the present invention, the influence is small.

The projections 3 and 3 'are connected at their tops.
The contact area of each contact surface when touched is 25 m for each projection
If it is m ² or less, of the, the adhesive material extends filamentous
And the contact area is significantly reduced.
If 5 mm ² or more, joined tray considerable pressure
The tray 10 can be prevented from bending even when the tray 10, 10 '
Of the adhesive material 6 can be prevented. Contact area is 5
If it is less than ² mm , the bending restraining force is small, and
May come in contact with the sticky substance. further
By lowering the height of the projection by 1 mm or more from the upper part of the periphery,
Even if an adhesive substance adheres to the projections, there is a gap between the projections
, So that when the trays 10 and 10 ′ are released, they form a thread
Can be prevented, and the height of the protrusion from the upper part of the periphery is within 4 mm
By holding the appropriate amount of adhesive substance in the tray
Can be.

[0011]

The tray according to the invention of the present application is constructed as described above, and is not used because the height of the projection as a spacer provided at the center is made 1 to 4 mm lower than the height of the peripheral bank. Sometimes, even when two trays are stacked with the adhesive substance surface inside, the tips of the projections do not come into contact with each other, and when the trays are released, the adhesive substance is prevented from extending in a thread shape.
Also, since the trays are stacked when not in use, there is no need to use expensive release paper and the cost can be reduced.
