Description

  The present invention relates to an animal breeding cage.

  As an animal breeding cage for breeding laboratory animals such as mice, rats, guinea pigs, etc., it has been conventionally formed from a net cage 100 formed of a metal net as shown in FIG. 9 or a synthetic resin as shown in FIG. In addition, a resin-molded cage 110 provided with a cage body 111 having a substantially rectangular shape in plan view and a bottomed cage body 111 and a cage lid 115 made of a wire mesh mounted on the cage body 111 has been used.

  When a conventional net cage 100 as shown in FIG. 9 is used, a tip opening 107 of a water supply nozzle 106 extending from a water supply pipe 105 of an automatic water supply device 104 for supplying water to a laboratory animal protrudes into the net cage 100. Then, the experimental animal ingests the water supplied from the water supply device 104 via the water supply nozzle 106 from the tip opening 107 inside the net cage 100.

  However, the net cage 100 as shown in FIG. 9 is hardly used at present due to the requirement of a breeding environment more suitable for breeding laboratory animals because the scaffold is unstable.

  In the case of the resin molded cage 110 of the prior art shown in FIG. 10, the supply nozzle 113 of the water bottle 112 is usually inserted between the wire meshes of the cage lid 115, and the experimental animal is supplied with the water nozzle inside the resin molded cage 110. Water is ingested from the tip opening 114 of 113.

  However, since the bottomed resin-molded cage 110 as shown in FIG. 10 is configured to be supplied with water inside the resin-molded cage 110, water is discharged from the tip opening 114 of the water supply nozzle 113 when the experimental animal drinks water. Water may accumulate in the resin molded cage 110 due to spilling. When water accumulates in the resin-molded cage 110, there is a problem that sawdust, waste paper, or the like that is a flooring becomes damp, and sometimes an animal is immersed in the resin-molded cage 110 and further drowns.

  The present invention has been made to solve the above problems, and an object thereof is to provide an animal breeding cage that prevents intrusion of drinking water into the animal breeding cage.

  The object of the present invention is to make all or part of the side surface of the animal breeding cage an inclined surface that forms an obtuse angle with respect to the bottom surface of the cage body, provide a through hole in the inclined surface, and provide a drinking hole in the through hole.

  Hereinafter, an animal breeding cage according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an animal breeding cage 1 according to the first embodiment. The animals raised in the animal breeding cage 1 include animals such as mice, hamsters, rats, guinea pigs, rabbits, dogs, cats, small monkeys, and particularly experimental animals. Animals include both adult and juvenile cases.

  The animal breeding cage 1 according to the first embodiment includes a cage body 2 made of a synthetic resin, and the cage body 2 has a bottom surface 3 and four side surfaces 4, 5, 6, 7 that are erected continuously from the bottom surface 3. And the upper ends of the four side surfaces 4, 5, 6, 7 terminate at an annular edge 8. An upper end edge 9 for engaging with a cage lid (not shown) is erected from the edge portion 8. The bottom surface 3 and the four side surfaces 4, 5, 6 and 7 define a space 10 for accommodating animals.

  Two protrusions 11 are provided at the upper central portion in the longitudinal direction of the side surfaces 5 and 7 of the cage body 1 and below the edge portion 8, and this is provided by the user of the animal breeding cage 1. When the cage 1 is transported, a finger is placed between the two protrusions 11 and the animal breeding cage 1 is lifted so as to press the edge 8 from below to function as a gripping portion that facilitates the transportation of the animal breeding cage 1. . Moreover, although the other protrusion 12 is provided in the four corners of the upper end part of the cage main body 1, when stacking several animal breeding cages 1, this is a buffer part which makes it easy to remove the animal breeding cages 1 from each other. Function.

  As shown in FIG. 2, the side surface 4 that is one of the side surfaces constituting the cage body 2 is an inclined surface in which the angle θ with respect to the bottom surface 3 of the cage body 2 forms an obtuse angle. Although the angle of θ is not particularly limited, for example, 90 ° <θ ≦ 135 °. That is, when the cage main body 2 is viewed in plan, the cross section of the cage main body 2 is reduced toward the bottom surface 3.

  As shown in FIGS. 1 and 2, a metal grommet 14 is attached to the substantially circular through-hole 13 provided in the side surface 4, and a domestic animal in the cage body 2 is attached to the grommet 14. A drinking hole 17 for ingesting water supplied from the outer water supply device 30 is provided. A member for opening and closing the drinking hole 17 is not attached to the grommet 14, and the drinking hole 17 is always open.

  As shown in more detail in FIG. 3A, in this embodiment, the drinking water hole 17 is substantially cross-shaped, and has a shape that prevents the animal body from protruding beyond the animal breeding cage 1 more than necessary. . The dimension of the drinking hole 17 can be appropriately set by those skilled in the art according to the dimension around the mouth of the animal. The reason that the grommet 14 is made of metal is to prevent breakage due to biting or scratching by animals. The grommet 14 is made of stainless steel, for example.

  As shown in FIG. 2, the grommet 14 includes a grommet body 15 and a substantially annular grommet ring 16. As shown in FIGS. 3A to 3C, the grommet body 15 includes a bottomed hollow cylindrical portion 15a and a flange 15b extending from the upper end of the hollow cylindrical portion 15a. , (B), the grommet ring 16 includes a substantially circular opening 18 having a dimension through which the hollow cylindrical portion 15a of the grommet body 15 passes. Returning to FIG. 2, the grommet main body 15 and the grommet ring 16 are inserted into the opening 18 of the grommet ring 16 from the bottom of the hollow cylindrical portion 15 a and fitted into the grommet main body 15 and the circumference of the flange 15 b of the grommet main body 15. The side surface 4 of the cage body 2 is sandwiched from both sides by the end portion and the peripheral end portion of the grommet ring 16. Thereby, the grommet 14 is firmly attached to the through hole 13 provided in the side surface 4.

  As shown in FIG. 2, when drinking water is supplied to an animal, the animal breeding cage 1 is arranged near an automatic water supply device 30 as a water supply device. The automatic water supply device 30 has one or a plurality of water supply nozzles 32 extending from a water supply pipe 31, and water is supplied from a tip opening 33 of the water supply nozzle 32. Here, when the animal breeding cage 1 of the present invention is used, the tip opening 33 of the water supply nozzle 32 of the automatic water feeder 30 is outside the animal breeding cage 1 and is separated from the animal breeding cage, and the animal drinks water. Place as far as possible. The animal can put its mouth out of the animal breeding cage 1 through the drinking hole 17 provided in the grommet 14 and press the tip opening 33 of the water supply nozzle 32 with the mouth to release water.

  In the animal breeding cage 1 of the present invention, since the side surface 4 is inclined with an obtuse angle with respect to the bottom surface 3, the animal breeding cage 1 automatically feeds water from the position of the tip opening 33 of the water supply nozzle 32 vertically downward. Leave the device 30. For this reason, even if water such as a water droplet 34 is spilled when an animal drinks, the water falls vertically downward outside the animal breeding cage 1 to prevent water from entering the animal breeding cage 1. Is done. If the water intrusion into the animal breeding cage 1 is prevented, it is possible to prevent the inundation of sawdust and paper scraps that are the floor in the animal breeding cage 1 and the drowning of small animals and animal pups. A more comfortable rearing environment is maintained.

  In addition, as the height d of the grommet body 15 of the grommet 14 is larger, water intrusion into the cage body 2 is more effectively suppressed.

  Thus, according to the animal breeding cage 1 of the present invention, the animal can drink the water supplied from the automatic water supply device 30 and can prevent water from entering the animal breeding cage 1.

  The animal breeding cage 1 according to the first embodiment of the present invention has been described above. However, the present invention is not limited to the first embodiment, and various modifications can be made without departing from the spirit of the present invention. There are also the following changes.

  The upper end edge 9, the protrusion 11, and the protrusion 12 of the cage body 2 in the first embodiment may take other shapes or may be omitted.

  The grommet 14 in the first embodiment may be one in which the grommet body 15 and the grommet ring 16 are integrally formed instead of separate members.

  In the first embodiment, the entire side surface 4 of the cage body 2 forms one inclined surface, but a part of the side surface 4 may form an inclined surface.

  For example, FIG. 5 is a schematic perspective view of an animal breeding cage 1 ′ according to the second embodiment of the present invention, in which the side surface 4 is continuous with the bottom surface 3 and extends at an obtuse angle with respect to the bottom surface 3. 4a, a first surface 4b extending in a substantially horizontal direction of the cage body 2 from the opposite side of the inclined surface 4a to the outside of the cage body 2 continuously from the inclined surface 4a, and a first surface 4b It has the 2nd surface 4c extended to the upper end of the cage main body 2 from the opposite side to the inclined surface 4a in the 1st surface 4b continuously.
