The present invention relates to an experimental animal carrying box used for carrying a laboratory animal, and more particularly, to secure the fastening of the box part and the lid of the experimental animal carrying box, and to carry out an experimental animal which can completely block the inside and the outside. It's about the box.

In general, experimental animals are provided with a box for carrying a laboratory animal in the form of a box for carrying.

Experimental animal transport box consisting of a box portion for receiving the laboratory animals and a cover portion covering the upper portion of the box is formed in a predetermined space therein breathing the experimental animal housed in the experimental animal transport box accommodated in the box portion or the cover portion A plurality of breathing holes are arranged so as to be possible, and a filter is provided to prevent contaminated air from passing through the breathing holes arranged in the box part or the cover part.

As described above, by closing the cover part after putting the animal to be transported in the box part of the experimental animal transport box having a configuration in which the box part and the cover part are separated, the test animal inside the experimental animal transport box is prevented from being separated to the outside.

However, the conventional laboratory animal carrying box as described above is not provided with a locking means for fastening the cover part firmly to the box part, and after the user inserts the experimental animal, the box part and the cover part are separated by the movement of the experimental animal housed therein. Often occurred.

In addition, most of the experimental animals carried through the experimental animal carrying boxes are infected with diseases or have a weak surface force in order to be used in experiments. Since there is no means to provide, the air inside the experimental animal transport box contaminated with bacteria may be leaked to the outside to infect the user, or the external bacteria or the like may penetrate inside to infect the laboratory animal with weak immunity. The case occurred. A filter is provided on the side or top of the experimental animal transport box to the outside of the breathing hole where the air required for the animal's breathing communicates, preventing movement of contaminated material, but through the gap between the cover and the box, contaminants such as pathogens. There was a problem moving between this inside and outside.

As described above, in the case of a conventional laboratory animal carrying box in which the box part and the cover part are separated and the inside and the outside are not provided with a separate locking means, the tape is wound around the upper part of the box part to overcome this problem. In order to prevent separation of the box and the cover and to ensure that the inside and the outside are sealed to each other, this method is inconvenient because the tape must be wound or released every time it is used, and it takes a lot of time to use. In addition, after use, there was a problem in the treatment of the contaminated tape generated separately from the experimental animal transport box.

In addition, although the conventional experimental animal transport box has an observation window for observing the inside of the cover part according to the regulations of the International Air Transport Association, the observation window is not provided on the side part, so that the multilayer When the experimental animal transport box is stacked, or if you want to use the experimental animal transport box for breeding indoors, it was inconvenient to observe the interior from the outside in a stacked state or on a shelf. In the case of stacking a large number of laboratory animal crates, it was inconvenient to move the other experimental animal crates loaded on the upper part until the experimental animal crates were revealed to observe the inside from the outside. The laboratory animal crates were taken down to examine the condition inside. However, in such a case, it was inconvenient for the user to move the experimental animal carrying box, and there was a problem in breeding due to the stress caused by the movement of the animals inside the experimental animal carrying box.

The present invention has been invented to solve the above problems, can be securely fastened the box portion and the cover portion, the inside and the outside is completely hermetic, transporting the laboratory animal to easily observe the inside from the outside The purpose is to provide a box.

In order to achieve the above object, the experimental animal carrying box of the present invention has a box part and a box in which an upper part is opened to accommodate an animal therein, a space is formed inside, and a respirator having a filter material attached to a side wall part is formed. In the laboratory animal carrying box consisting of a cover portion fastened to the upper portion of the upper portion, a locking rib having a predetermined thickness and height formed downward along the periphery of the upper surface of the box portion, one end is pivotally connected to the outside of the cover portion And a locking lever having a projection formed at the other end thereof, and engaging the box portion with the lid portion by engaging the other end portion of the locking lever with an end of the locking rib, and having a shape corresponding to the cross section of the box portion 10. The upper plate is provided with a divider plate 60 having a protrusion 61 having a 'T' shape, and formed on the inner lower surface of the box part 10. A part of the side end and the lower end is inserted into the number of divider insertion grooves 18, and the partition plate having a shape corresponding to the protrusion 61 on the upper surface of the box part 10 so that the protrusion 61 can be inserted. It is preferable that the separation preventing groove 19 is formed.

Here, the outer side of the locking ribs of the upper portion of the box portion when the box portion and the cover portion is coupled to the outer side of the locking ribs made of the same material as the other portion of the box portion, the thickness is thin and has a predetermined height is formed .

In addition, it is preferable that the support ribs are formed downward on the bottom surface of the cover part to have a predetermined height at a predetermined distance from the edge so as to support the upper surface of the box part when the box part and the cover part are fastened.

In addition, the side wall portion of the box portion may be provided with a side observation window through which light can be transmitted to observe the inside.

A partition plate having a shape corresponding to a cross section of the box portion and further having a 'T' shaped protrusion is formed at both ends of the box portion, and a part of the side end and the bottom of the plurality of partition plate insertion grooves formed on the inner lower surface of the box portion is formed. Inserted, the protrusion is characterized in that the partition plate separation prevention groove formed in the upper surface of the box portion is formed.

A loading rib having a cross section protruding in a 'L' shape may be formed on the bottom surface of the box portion, and a loading protrusion may be formed on the upper surface of the lid portion to correspond to the loading rib.

Referring to the configuration of the experimental animal transport box of the present invention using the accompanying drawings as follows.

The experimental animal carrying box according to the present invention is mounted inside the box part 10, the cover part 30 covering the upper part of the box part 10, and the box part 10 to accommodate the test animal to be carried. The partition plate 60 which divides the inside of the part 10 into several spaces is made into a main component.

The box part 10 is formed to have an upper portion open to accommodate an animal therein and have a predetermined width, width and depth. The box portion 10 is manufactured by an injection process using a synthetic resin material to facilitate processing. In particular, the box portion 10 is preferably made of polypropylene, so that the box portion 10 has an overall translucent state.

The bottom surface of the box portion 10 is formed flat, preferably has a rectangular shape, and side wall portions 11 and 12 are formed upwardly from the periphery of the bottom surface. The side wall parts 11 and 12 are formed to be wider toward the upper side, and the upper surface 15 of the side wall parts 11 and 12 is formed along a circumference of the box part 10 in a plane having a predetermined width.

The box part 10 has side wall parts 11 and 12 formed to widen from the bottom to the upper part, and when only the box part 10 is separately loaded when not in use, the box part 10 has another test part inside the box part 10. The box portion of the animal carrying box can be accommodated, thereby reducing the space required for storage.

The side wall portion 11 of one side and the side wall portion 11 facing the side wall portion 11 of the one side is arranged with a plurality of breathing holes 13 at regular sizes and intervals so that the laboratory animals can breathe.

In addition, the filter medium 50 is attached to the outside of the plurality of breathing holes 13 arranged in the side wall portion 11 to prevent the spread of contaminants such as pathogens. The filter medium 50 having a fine air passage is formed wider than the area in which the breathing holes 13 are arranged and attached to the outside of the breathing holes 13, so that pure air can move inside and outside the experimental animal transport box. However, it prevents the passage of contaminants such as pathogens, dust, etc. suspended in the air. At this time, the filter medium 50 is made of a synthetic resin such as polypropylene made of the same material as the side wall portion 13, and the method of attaching the filter medium 50 to the arrangement of the breathing hole 13 of the side wall portion 11 is ultrasonic Add the fusion method to use.

Around the upper surface 15 of the side wall portions 11 and 12, a locking rib 16 and a thin portion 17 are formed for tight fastening and airtight inside and outside, as shown in FIG. do. Locking ribs 16 having a predetermined thickness are formed along the circumference of the upper surface 15 so as to face the outer bottom, and locking means formed on the cover part 30 at the lower end of the locking ribs 16. By using the box portion 10 and the cover portion 30 can be fastened so as not to be separated.

In addition, the outer side of the locking rib 16 is thinner than the other portion along the circumference of the upper surface 15, the height is lower, and forms a thinner portion 17 which is slightly lower outwardly than the locking rib 16. When the cover part 30 is coupled to the box part 10, the thin part 17 is brought into close contact with the inner surface of the cover part 30 to form an inner space formed of the box part 10 and the cover part 30. Do not let the outside communicate with each other. The thin part 17 is formed of the same material as the other parts of the box part 10, but because the thickness is thin, it is flexible compared to other parts, so that the bottom of the cover part 30 and the box part 10 when the box part 10 is combined In close contact with the side surface, the minute amount is bent toward the locking rib 16 to seal the box part 10 and the cover part 30.

On the other hand, another side wall portion 12 is not formed with the breathing hole 13 is to be formed side observation window 14 to observe the inside. Laboratory animal crates are primarily used to carry laboratory animals, but are sometimes used to raise animals. The side wall portion 12 is made of the same material as the other parts of the box portion 10, but multiply the surface roughness to form a side observation window 14 through which light can be sufficiently transmitted.

The side observation window 14 is formed in the experimental animal carrying box, so that the inside can be easily observed when the experimental animal carrying box is stacked in multiple layers or when the experimental animal is stored or raised while being mounted on a shelf or the like. do.

At this time, the side observation window 14 formed in the side wall portion 12 of the box portion 10, even if a step is formed on the inner side so that the step is not formed with the side wall portion 12. This causes stress on the experimental animal by visually opening the side wall portion 12 during transportation in the state of accommodating the experimental animal, in order to facilitate the adhesion and removal of the film attached from the outside to prevent this.

Then, the handle 20 is formed on the lower side of the upper surface 15 to facilitate the carrying on both sides of the upper portion of the box portion 10. In addition, around the lower portion of the upper surface 15, the box portion 10 has a certain strength in various places, and can maintain the initial shape, and reinforcement to withstand the load of other experimental animal carrying boxes loaded on the upper side when multi-layer loading. Ribs 22 are formed.

In addition, a plurality of loading ribs 21 having a 'L' shape in cross section protrudes from the bottom of the box portion 10 (see FIG. 5).

The cover part 30 is formed in a size corresponding to the size of the upper part of the box part 10 so as to close the open upper part of the box part 10. The cover part 30 is formed in a plate shape, and the edge is bent downward along the circumference so that the thin part 17 formed at the outermost part of the upper surface 15 of the box part 10 may be included. The entire cover part 30 covers the upper part of the box part 10, and a part bent along the circumference of the cover part 30 surrounds the upper surface 15 of the box part 10 so as to surround the box part 10. ) And the cover portion 30 to be fastened. In the center of the cover portion 30, as in the side wall portion 11 of the box portion 10, the breathing holes 31 are arranged, and the filter medium 50 is fused to the outside of the breathing holes 31 using ultrasonic waves. . In addition, a plurality of upper observation windows 31 are formed on the upper surface of the cover part 30 to observe the inside. The material of the cover part 30 is preferably made of a synthetic resin such as polypropylene as the material of the box part 10.

A plurality of lock levers 33 are formed around the cover part 30 so that the box part 10 and the cover part 30 can be completely fastened. As shown in Figure 7a and 7b the upper part of the box portion 10 and the end of the cover portion 30 is shown in detail, one end is pivotally connected around the cover portion 30, the other end The cover part 30 and the box part 10 are completely fastened by using the locking lever 33 having a protrusion projecting downward. The locking lever 33 has the same material as the cover part 30 and is integrally formed by molding, etc., but the part where the locking lever 33 is connected to the cover part 30 is thinner than other parts. The locking lever 33 can easily pivot around the lid portion 30, and projections are formed at the other end thereof, so that the lid portion 30 is placed on the upper portion of the box portion 10 (Fig. 7A). The other end of the locking lever 33 is rotated to be caught by the end of the locking rib 16 of the box portion 10 (Fig. 7B). In this state, the end of the locking lever 33 is caught at the end of the locking rib 16 to prevent the cover 30 from being separated from the box 10.

In the state where the box part 10 and the cover part 30 are fastened, the thin part 17 of the box part 10 is brought into close contact with the inside of the bent portion around the cover part 30. Inside and outside are completely sealed. In a conventional experimental animal carrying box, the box part 10 and the cover part 30 are not completely sealed, so that contaminants such as pathogens often pass to this part, and the box part 10 is cumbersome to prevent this. And the sealing portion 30 was sealed using a tape, but in the experimental animal transport box of the present invention is thinner than the other portions, the thin portion 17 having flexibility is formed around the box portion 10, the lid portion Since it is in close contact with the inside of (30), even without a separate taping operation, the inside and the outside is sealed to prevent passage of contaminants such as pathogens.

At this time, a support rib 34 formed at a predetermined height at a predetermined distance from the edge is formed on the bottom surface of the cover part 30 along the circumference. The support ribs 34 support the upper surface 15 of the box portion 10 when the box portion 10 and the cover portion 30 are fastened from the inside. Accordingly, as shown in FIG. 7B, the upper surface of the box portion 10 is inserted into a space formed by the support rib 34 and the edge of the cover portion 30 on the bottom surface of the cover portion 30, thereby providing a box portion ( The upper surface 15 of 10 is supported by the support ribs 34 on the inner side, and the locking lever 33 is locked by the combination of the locking lever 33 and the locking rib 16 on the outside. To prevent the phenomenon that the fastening force is weakened by being separated from, and the airtightness of the thin portion 17 is reduced.

On the other hand, the periphery of the cover portion 30 is formed with a connecting projection 35 for preventing the flow of the experimental animal transport box horizontally adjacent, the upper surface loading projection 36 to be loaded in a multi-layer experimental animal transport box ) Is formed. The connecting protrusion 35 is formed in the circumference of the cover portion 30 having a rectangular shape, so as to have a shape corresponding to each other and the sides facing each other, the connecting protrusion of the adjacent experimental animal transport box when loaded horizontally ( 35) to prevent it from flowing horizontally. In addition, the upper surface of the cover portion 30 is formed with a plurality of loading projections 36, coupled to the 'L' shaped loading ribs 21 formed on the bottom of the box portion 10 so as to correspond to this, an experimental animal It should be used for vertical stacking of transport boxes.

The partition plate 60 is provided inside the box part 10 so as to divide the space of the box part 10 as necessary.

The partition plate 60 is formed in a shape corresponding to the cross section of the box portion 10 to divide the space of the box portion 10 when mounted on the box portion 10. The box portion 10 is formed in a form in which the side wall portions 11 and 12 are widened toward the bottom, and the partition plate 60 is preferably formed in a Sarari shape. In order to mount the divider 60 to the box part 10, the divider insertion groove 18 is formed at a place where the divider 60 is inserted into the box part 10.

In particular, in order to prevent the divider 60 inserted into the box part 10 from being separated from the divider 60 mounted in the box part 10 by the animal's violent movement, the upper end of the divider 60. Protruding portions 61 having a 'T' shape are formed on both sides, and the separation plate departure preventing grooves 19 corresponding to the protrusions 61 of the divider 60 are formed on the upper surfaces of the side walls 11 and 12. Do it. Therefore, the partition plate 60 is not only mounted by the partition plate insertion groove 18 of the box portion 10, but also has a 'T' shape formed at both ends of the upper part of the partition plate 60 as shown in FIG. Since the protrusion is inserted into the divider insertion groove 18 of the upper surface of the side wall portion 11, the divider 60 is detached from the box portion 10 even if the animal housed in the box portion 10 appears to be an abnormal extreme movement. This can prevent other animals in the same box from being injured.

Experimental animal carrying box of the present invention as described above, the locking lever of the cover part is locked to the locking rib of the box part, thereby preventing the use of the box part and the cover part of the experimental animal carrying box separated.

In addition, the thin part formed along the upper periphery of the box part is in close contact with the inside of the cover part, so that the inside and outside of the experimental animal transport box is hermetically sealed, so that contaminants such as pathogens do not spread.

Since the partition is formed on the upper part of the partition plate and the partition plate separation prevention groove is formed in the upper surface of the box part, the partition plate is prevented from being separated from the box part by the animal's violent movement and is accommodated in the separated space. Animals that should be left unintentionally solve the problem of mixing with each other by separation.
