Description

[Detailed Description of the Invention] The present invention relates to a powder feeder for small animals that can be set in a cage for housing small experimental animals such as mice and rats.

In general, powder feeders, which are used to house small experimental animals such as rats and mice, are used to make it possible to mix drugs and add specific ingredients. Feed is eaten through the feeding port, but in this type, animals often climb onto the feeding port, making it difficult for feces, urine, bedding material, etc. to be carried in, which tends to contaminate the feed. For this reason, in recent years, there has been a shift to a type that uses a housing type feeder with a funnel-shaped structure at the bottom, and feeds feed sequentially from a feeding port located at the bottom end. However, this housing-type feeder is a fixed type that is simply attached to the cage body, and there are problems such as overflowing of feed and clogging, and although various improvements have been made, there is still nothing satisfactory. Particularly, when the feed is powdered powder with some moisture (including chemical solution) added to the powder, the clogging phenomenon continues.

In view of the above-mentioned circumstances, the object of the present invention is to provide a powder feeder for small animals in which the feeder itself is oscillated to ensure smooth feed supply.

That is, in the present invention, the main body of the rectangular feeding device has a funnel shape with the lower part of the rear wall tilted forward, and the bottom part is also tilted forward, and the front edge of the bottom protrudes forward from the lower end of the front wall to provide an upward feeding opening. It has a housing structure with a rocking support piece protruding from the upper edge of the opposite side walls to support the canopy of the cage body in a hanging manner, so that small animals only need to touch the feeding port. This shakes the entire feeder to make the feed flow out smoothly.

Hereinafter, the present invention will be explained based on the drawings of embodiments.

Figures 1, 2, and 3 show a powder feeder for mice, in which 1 the lower part 2a of the rear wall 2 is tilted forward to form a funnel-shaped tank;
The front edge 3a of the slanted bottom 3 connected to the front wall 4 is protruded slightly forward from the lower end of the front wall 4, and the tip of this front edge 3a is hooked upward by an appropriate width to form an upward opening at the front side of the front wall 4. This is a housing-type feeder main body in which a feeding port 5 having a feeding port 5a is formed. Support pieces 7, 7 are provided to protrude outward. The support pieces 7, 7 may be formed by using a convex configuration in which the side wall 6 surface is punched out, or a penetrating horizontal bar (not shown) may be provided, and both protruding ends may be used as the support pieces. In short, it is sufficient that the left and right support pieces 7, 7 hang on the set opening rim 8b provided on the canopy part 8a of the cage body 8, and the feeder body 1 is suspended in a swingable manner.

Reference numeral 10 denotes an outlet section formed between the lower edge of the front wall 4 and the bottom section 3. A regulating horizontal bar 11 is provided at the center of the outlet section 10 to prevent entry, and the powder feeder 1 as a whole is '.

To explain how it works, first, this powder feeder 1' is fitted into a square set lip 8b attached to the top 8a of a cage body 8 of known shape, and support pieces 7, 7 protruding from both ends of the upper edge 1a of the feeder body 1 are hung on the set lip 8b in a suspended state. Powdered feed A is filled into this feeder body 1 beforehand. In this case, the support pieces 7, 7 are positioned forward (towards the front wall 4) of the center of gravity of the feeder body 1, so that when set, the rear of the feeder body 1 is lowered by the weight of the feed, and the front feeding mouth 5 is raised, creating an inclined suspended position (see the two-dot chain line in Figure 4).

Here, a mouse (not shown) tries to eat the feed A in the feeder main body 1, approaches the feeding port 5 where the feed A is visible in the outlet 10 from the outside, and enters the feed port 5 into the feeding port 5. Or, if you touch it with your hand, the feeding device main body 1, which is tilted as a whole in advance, is a swinging type of hanging using the support pieces 7, 7 as unstable elements as a fulcrum, It becomes something you can look back on. Moreover, this support piece 7,
7 is located in front of the feeding device main body 1 to obtain a large swing width,
Due to this vibration, the feed A in the feeder main body 1 is transferred to the funnel part 1.
It is pushed out from b through the outflow port 10 to the feeding port 5 and can be eaten. in this case,
Even if the mouse sticks its mouth into the outlet part 10 on the front wall 4 side and tries to enter the tank, the outlet part 10
Because the regulating horizontal bar 11 serving as a horizontal bar is arranged in the center, the feed A that has accumulated in the feeding port 5 is eaten from the upper opening. However, due to the habit of rodents, they tend to use their hands to scrape out the clogged feed A that is visible inside the outlet 10, and insert their hands into the upper part 10b of the outlet 10, so from this point as well, the inside of the tank is Since a gap is formed at the lower part of the feeding port 10b, the feed can be fed sequentially from the lower part 10b to the feeding port 5 side without causing clogging. (Incidentally, the gap at the outlet is about 16 mm, with a horizontal regulating bar placed in the middle, and the width of the feeding port is narrow, about 10 mm. From this point of view, it is difficult to get onto the feeding port. is not possible).

As mentioned above, the powder feeder for small animals of the present invention has a structure in which the main body of the feeder is funnel-shaped and a support piece that serves as a swinging fulcrum is placed on the upper edge, making it easier for small experimental animals to eat the feed. As a result, the main body of the feeder shakes upon contact with the feeding opening, and the feed automatically flows out toward the feeding opening. Furthermore, since the outlet at the lower end is exposed at the front position, it not only whets the appetite but also allows for easy scraping out by inserting your hand. From this point as well, together with the vibration, smooth outflow is caused. Of course, in the case of extremely small animals such as mice, if a horizontal bar (regulating horizontal bar) is interposed at the outlet, they will not enter the tank. In addition, the narrow width of the feeding opening and the swinging of the main body itself provide practical effects such as preventing entry into the feeder and preventing contamination of the feed.
