Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for observing, breeding, or housing animals and plants including insects (insects such as stag beetles, beetles, bell worms and crayfish).
Preferably, it relates to a breeding box used for breeding stag beetles

[0002]

2. Description of the Related Art A wide variety of insect cases have been sold in the past, but all of them are strongly conscious of the lack of oxygen in the insects contained therein, so that relatively large air cases having a diameter of about 2 mm are used. A lid with an insertion hole is used,
At the center of the lid, an openable insect take-out port is provided.

[0003] By the way, fruit and insect jelly are used as beetles and stag beetles. Drosophila almost always occur in these baits,
The breeding can freely enter and exit through the air insertion hole, causing a problem in hygiene. On the other hand, cloth, flexible mesh, paper, etc. are sandwiched between the case body and the lid. However, in this case, if the number is large, it is troublesome, and further, beetles, stag beetles, etc. There is a problem that it is easily broken by a strong insect.

In recent years, a method using fermented wood chips has been established as a method of breeding stag beetle larvae, and this method has been practiced at a high frequency. However, the mat has a small fly that is smaller than the Drosophila generated in the bait. , And can easily enter and exit through the air insertion hole more easily than the Drosophila that occurs in the bait. Moreover,
Normally, dozens of larvae can be obtained from adult stag beetles.However, due to the nature of the larvae eating each other, it is necessary to prepare separate breeding cases for each, and therefore, the rotten fly that comes out of the cases. The total volume was extremely high, a very painful problem for breeders.

In recent years, it has become uncommon for large powerful insects such as large stag beetles to be bred. As a result, a claw is caught in the air insertion hole of the lid and caught and squeezed, and the insect can be taken out with the strong jaw. There have been many reports of accidents in which the lid itself was forcibly opened to escape. Or, even if they do not escape, there have been many reports of accidents where the mandible was caught in the air hole and suspended and suspended, the mandible was broken, and even if the nails and arms could not be pulled out, they could be bald. Most of the causes are due to the size of the air insertion hole into which the nail or the large jaw can enter.

Further, in the conventional breeding box, since a relatively large air insertion hole is formed in a wide area of the lid, moisture is excessively released from the air insertion hole,
The inside of the breeding box was supposed to be too dry. Therefore, it is necessary to appropriately add water to the inside of the breeding box, which is troublesome especially when the number of breeding boxes is large.

[0007]

DISCLOSURE OF THE INVENTION The present invention was conceived to solve the above-mentioned problems, and is caused by Drosophila which is generated in the feed of beetles and stag beetles and small flies which are generated in wood chips subjected to fermentation treatment. The primary objective is to solve hygiene problems.

Another object of the present invention is to prevent the stag beetle from escaping by opening the lid using an air insertion hole formed in the breeding box.

It is still another object of the present invention to prevent a damage accident and a fatal accident due to a part of a body being caught in an air insertion hole formed in a breeding box.

[0010] Yet another object of the present invention is to prevent excessive release of water from the breeding box.

[0011]

In order to achieve the above object, the technical means adopted by the present invention is to form an air insertion hole in a desired portion of a living box, and to make the size of the air insertion hole shorter in the lateral direction. Is less than 1 mm. Preferably, the dimension of the short side direction of the air insertion hole is set to 0.1.
It is characterized by being 8 mm or less. It has been found that by setting the dimension of the air insertion hole in the widthwise direction to less than 1 mm or less, the entry of small flies such as Drosophila can be well controlled. More preferably, it has been found that by setting the dimension of the air insertion hole in the widthwise direction to 0.8 mm or less, it is possible to restrict the invasion of all possible small flies.

[0012] In particular, there are many types of small flies generated when breeding stag beetles, and it is difficult to specify all of them. Potential occurrences include Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster, Drosophila melanogaster Drosophila, Drosophila melanogaster, Yellow Drosophila, Drosophila melanogaster, Susabaen Drosophila, Drosophila melanogaster, Drosophila melanogaster, Coleoptera, Coleoptera Madara Hayato fly is conceivable. However, it is undeniable that small flies other than these may occur, and the type of small flies targeted by the present invention is not limited to these. At least, as shown in the experimental results described later, it was found that the entry and exit of the small fly could be regulated by setting the dimension of the air insertion hole in the short direction to less than 1 mm, preferably 0.8 mm or less.

In this specification, the term "transverse direction" is used to indicate the shortest side of the opening dimension of the air insertion hole. Therefore, when the air insertion hole is circular, the diameter is less than 1 mm, more preferably 0.8 mm or less, and when the air insertion hole is elliptical, the minor diameter is less than 1 mm, more preferably 0.1 mm or less. It is an ellipse of 8 mm or less. Further, when the air insertion hole is a slit, the width of the slit is less than 1 mm, more preferably 0.8 mm
The following slits.

By selecting the area occupied by the air insertion hole, it is possible to prevent excessive release of water in the storage box. Since the opening size of the air insertion hole according to the present invention is small, it is possible to reduce the release of water as compared with a conventional insect breeding box by forming the air insertion hole to be somewhat sparse.

Another technical means adopted by the present invention is a living organism box having an air insertion portion formed at a desired site, wherein the air insertion portion has a double wall structure composed of an inner wall and an outer wall. The inner wall is formed of a rigid member and has an air insertion hole, and the outer wall is formed of an air-permeable sheet material. As the air-permeable sheet constituting the outer wall, a nonwoven fabric, a woven fabric, paper, a mesh-shaped metal sheet, a resin sheet having an air insertion hole, or the like can be adopted. As a result of extensive studies by the applicant, it has been found that some small flies can pass through holes having a diameter of about 0.5 mm. Therefore, it is advantageous to employ a non-woven fabric, a woven fabric, or paper (which can be considered to have a hole having a diameter of substantially 0.5 mm or less) as the outer wall. Regarding the specific configuration of the double structure, preferably, a recess is formed in the lid of the biological storage box, and the bottom wall of the recess forms an inner wall, and covers the opening of the recess. It is preferable to provide an outer wall. However, conversely, a convex portion may be formed on the lid, and the upper surface of the convex portion may be used as the outer wall.

In a biological container having relatively large air holes (for example, air holes of a commercially available insect breeding box), a sheet is interposed between a wall surface on which the air holes are formed and an inner space of the storage box. The sheet may be formed with an air insertion hole having a short dimension of 1 mm or less, preferably 0.8 mm or less. This is economical because a conventional insect breeding box can be used. The sheet is made of a material such as hard plastic so that it is not broken by strong insects such as beetles and stag beetles.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described using an insect breeding box as an example. FIG. 1 is a schematic perspective view of an insect breeding box, wherein the insect breeding box 1 includes a bottomed main body 2,
A lid 3 is detachably mounted on the upper end side of the main body 2, and a plurality of air insertion holes 4 are formed in the lid 3.
Note that an opening (not shown) for taking out insects is formed in the lid 3.

The air insertion hole 4 formed in the cover 3 is a substantially circular opening and has a diameter of 0.8 mm.
This dimension of 0.8 mm is a dimension obtained as a result of extensive experiments by the applicant.

When stag beetles or stag beetle larvae are bred, small flies such as Drosophila are generated. In particular, small flies generated in wood chips used for breeding of stag beetles are smaller than those in feed. is there. Therefore, if the air insertion hole has such a size that the fly generated in the wood chips cannot pass through, the Drosophila generated in the bait cannot pass through the insertion hole.

Then, while changing the size of the circular insertion hole, an experiment was conducted to determine the size of the hole through which the fly generated in the wood chips can pass. In the case of an insertion hole having a diameter of 1 mm, it was possible to regulate the entry and exit of Drosophila generated in the food of the fruit, but it was found that some of the flies generated in the wood chips passed through this.
Therefore, the size of the insertion hole needs to be at least less than 1 mm in diameter. Next, when an experiment was performed using an insertion hole having a diameter of 0.8 mm, it was found that flies generated in wood chips could not pass through the hole.

Next, a prototype of a lid having 0.8 mm diameter air insertion holes formed vertically and horizontally in a lattice shape is produced as a prototype, and whether the insect can be caught upside down by this lid and can be caught. In such a case, an experiment was conducted to determine whether or not sufficient depression could be made to open the lid. In addition, an experiment was performed to determine whether the horns and jaws of the insect enter the air insertion hole having a diameter of 0.8 mm.

As the insects, large stag beetles and black stag beetles were selected. However, since the size of individuals differs greatly due to acquired factors such as nutrition in the larval era and innate factors such as genes of parent larvae, the insects are large and small, respectively. The experiment was conducted by selecting medium and small sized ones.

As a result of the experiment, in a lid using an air insertion hole having a diameter of 0.8 mm, it is impossible for a large individual to catch upside down on the lid, and even for a small individual who could barely catch the lid, It has been determined that it is not possible to squeeze enough to dig a hole. It was also found that the corners and jaws did not fit in the air insertion holes. When the same experiment was performed on the insertion hole having a diameter of 1 mm, similar results were obtained.

The shape of the air insertion hole is not limited to a circle, but may be any other shape as long as the dimension in the short direction is 1 mm or less, preferably 0.8 mm or less. 2 and 3 show another embodiment of the air insertion hole. FIG. 2 shows an elliptical air insertion hole 4a having a short diameter of 0.8 mm, and FIG. A slit-like air insertion hole 4b is shown. However, it is considered that the circular shape of the air insertion hole is less likely to catch insect claws and the like than the slit.

Although the material of the lid is not limited, it is desirably made of a material that will not be broken by strong insects such as stag beetles and beetles, and is preferably formed of hard plastic or metal mesh. You.

The air insertion hole may be formed by combining a plurality of members. In FIG. 5, two plates having an air hole having a dimension in the short direction of 0.8 mm or more are shown. Are overlapped, and the amount of the shift is variable, so that the size of the effective air insertion hole 4d can be adjusted.

The portion where the air insertion hole is formed is not limited to the lid, and may be formed, for example, at a position above the side wall of the main body. Further, the air insertion hole is not limited to the hole formed in the wall of the breeding box. As shown in FIG. 6, a sheet 7 having an air insertion hole may be interposed between the main body 20 and the lid 30 of the commercially available insect breeding box 10. The sheet 7 is made of a hard plastic. The general commercially available insect breeding box 10 is formed with a relatively large air insertion hole (for example, the dimension in the short direction is 2 mm or more).

Although FIG. 1 shows an example in which an air insertion hole is formed on the wall surface of the lid itself, the air insertion hole may be formed as a result. For example, in FIG. Shows that a sealing material 5 having an air insertion hole 4c of 0.8 mm or less is adhered to a wall surface 6 having an air hole of a commercially available insect breeding box.

Further, it was found that in the insect breeding box provided with a plurality of small air insertion holes having a small diameter of 0.8 mm, excessive evaporation of water was clearly regulated as compared with the commercially available insect breeding box. . Evaporation of water in the breeding box is an important factor in the area of the entire air insertion hole relative to the volume in the box, but by reducing the diameter of each air insertion hole, a container that can easily regulate evaporation of water is improved. It is thought that it can be produced.

It is considered that the small amount of evaporation of water means that the amount of air supplied through the air insertion hole is small as compared with the conventional breeding box. Therefore, when an experiment was conducted by actually inserting insects into a case having a lid with an air insertion hole with a diameter of 0.8 mm to supply oxygen required by insects, it was sufficient for insect respiration. Was confirmed.

FIG. 7 is a schematic side view showing another embodiment, in which a part of the lid 300 is formed in a concave shape, and an air hole having a relatively large size is formed in the concave portion. ,
An air-permeable sheet 8 exemplified as a cloth is provided on the upper end of the concave portion.
Is stuck. Since the cloth 8 can let air through,
It can be considered that a plurality of air insertion holes having a dimension in the short direction of 0.5 mm or less are formed in the cloth. The stag and beetles contained in the breeding box cannot touch the cloth directly, so that the cloth is not broken.

The configuration shown in FIG. 7 will be described in more detail with reference to FIGS. The feature of the air insertion portion in FIGS.
a) and the outer wall (the air-permeable sheet 8 in the illustrated example) has a double structure. The inner wall is made of a hard material such as hard plastic (the effect of having a hardness not broken by stagnation).
A plurality of air insertion holes 40 are formed in the inner wall. The air insertion hole 40 formed in the inner wall is a hole having a diameter of about 0.8 mm to about 2 mm, and has a size such that a jaw or the like of a stag is not caught or inserted.

In the embodiment, the outer wall is made of a non-woven fabric, but may be a woven fabric, a paper, an air insertion hole (a hole of about 0.5 mm if the minimum small fly is prevented from entering). (Preferably) or a metal sheet. It can be considered that a non-woven fabric, woven fabric, paper, or the like has an air insertion hole of substantially 0.5 mm or less. Because the stag jaws etc. do not reach the outer wall,
The member constituting the outer wall does not need to be rigid, and cloth or paper can be used for the outer wall.

The specific structure of the double structure will be described. The bottom wall 300a of the recess formed in the lid 300 forms an inner wall, and a plurality of air insertion holes 40 are formed in the bottom wall 300a. In FIGS. 8 and 9, the air passage hole is not formed in the side wall of the concave portion, but the air passage hole may be formed in the side wall. A frame 9 is provided in which an air-permeable sheet 8 exemplified as a nonwoven fabric is stretched over the recess. The frame body 9 has four upper and lower openings, a nonwoven fabric is stretched in one opening, and has a size corresponding to the recess,
The nonwoven fabric stretched over the frame 9 is provided in the recess so as to be substantially flush with the upper surface of the lid 300. In another form, the edge 9a may be formed on the upper surface of the frame 9, and the nonwoven fabric 8 may be sandwiched between the edge 9a and the plate 9b.

[0035]

Since the present invention is constructed as described above, it has the following advantageous effects. (1) By setting the dimension of the short side of the air insertion hole to less than 1 mm, preferably 0.8 mm or less, small flies such as Drosophila generated in food such as fruits and wood chips can freely enter and exit through the air insertion hole. And thereby prevent the breeding of the fly and solve problems in hygiene. (2) By setting the dimension of the air insertion hole in the short side direction to less than 1 mm, preferably 0.8 mm or less, it is possible to prevent a part of the body such as a nail or a jaw from being locked in the air insertion hole. In addition to preventing escape of insects and the like, it is also possible to prevent damage to parts of the body or death. (3) In the case where the air insertion portion has a double structure, the presence of the outer wall can prevent particularly small fly from entering, and even when the outer wall is made of cloth or paper, The outer wall is not damaged by the stag beetle or the like.
