Description

The present invention relates to a feeding device that floats on the surface of the aquarium in which an ornamental fish swims, keeps the bait sown on the surface of the water within a certain range, and feeds the fish in the aquarium.

The bait sprinkled on the surface of the aquarium is quickly scattered over a wide area, and many of them sink to the bottom of the water before it enters the mouth of the fish. As a solution to this problem, a tubular feeder that is used by floating on the surface of the water has been known for some time.

For example, Patent Document 1 discloses a feeding tool having a structure in which a suction cup or a hook is provided on an outer peripheral surface of a cylindrical main body, and a feeding tool having a structure in which a float is provided around the cylindrical main body. There is. Further, Patent Document 2 discloses a feeding tool having a structure in which a square tubular main body (feeding port) and a saucer are connected so as to face each other in the vertical direction.

These feeders support the tubular feeder body so that it sinks into the water from the bottom to the middle position in the height direction and the part above it is above the water surface, and inside the cylinder. By putting the bait, the bait stays in the cylinder, attracts the fish below it, and feeds it.

However, in order to maintain the above-mentioned arrangement state with the feeding tool described in Patent Document 1, parts such as a suction cup, a hook, and a float are required. The feeding tool described in Patent Document 2 also requires a hook as described in paragraph 0022 of the same document.

If a suction cup is used, the feeding tool main body can be stably attached to the aquarium, but if the suction force is strong, it becomes difficult to remove the main body. On the contrary, if the suction force of the suction cup is weak, the main body will come off immediately and it will not be usable. Further, if the suction cup is always attached to the aquarium, the suction cup becomes dirty and unsightly, and when the water level changes, the arrangement state suitable for holding the bait cannot be maintained.

Depending on the thickness of the glass of the aquarium, the hook may not be attached to the aquarium well, and the feeding tool main body may tilt or the hook may come off and the main body may sink into the water. The float has a problem that it puts a burden on the fish because it is difficult to keep the main body of the feeder in a certain place.

The present invention has been made by paying attention to the above problem, and is a feeding tool for aquarium fish that does not require a part to be mounted on the aquarium and can be stably supported on the inner wall surface of the aquarium only by the main body. The challenge is to provide.

To solve the above problems, in the present invention, openings are provided in both of two surfaces facing each other in the vertical direction, and at least one peripheral wall portion connecting the surfaces is provided with a flat surface along the vertical direction. A feeding tool with a hollow member is provided. This feeder has buoyancy that allows it to float on the surface of the water while maintaining a state in which the part above the intermediate position in the height direction (predetermined position above the lower edge of the peripheral wall and below the upper edge) is above the surface of the water. It has enough strength to prevent the peripheral wall from being deformed even in water. Further, in this feeding tool, when the flat surface of the peripheral wall portion is brought into contact with the inner wall surface of the water tank by floating on the water surface of the water tank containing water, the flat surface of the water tank is caused by the surface tension of water generated between the two. It is sucked on the inner wall surface.

According to the above configuration, even if parts such as suction cups and hooks are not used, the range from the upper end edge to the predetermined height position can be kept out of the water surface and floated on the water surface of the aquarium. It can be maintained and mounted in place on the inner wall of the aquarium. Since it has enough strength to prevent the peripheral wall from being deformed even in water, it is possible to stabilize the range in which food can be held. Since it is attached to the aquarium only by the action of the surface tension of water, it is easy to remove.

In the feeding tool according to the embodiment of the present invention, a peripheral wall portion having a triangular or polygonal outer peripheral shape and all the surfaces of the outer peripheral portion are flat surfaces along the vertical direction is adopted. According to this feeding tool, all the surfaces constituting the outer peripheral surface of the peripheral wall portion can be sucked to the inner wall surface of the water tank. In addition, by providing a corner portion close to a right angle at at least one of the outer peripheral portions, the two surfaces that are connected across the corner portion are attracted to the two continuous inner wall surfaces that sandwich the corner portion of the aquarium, respectively, to feed the feeding tool. It is possible to further stabilize the mounting state of the water tank.

The feeding tool according to another embodiment of the present invention has a triangular or square outer peripheral shape having a notch formed at least in one corner thereof, and all the surfaces of the outer peripheral portion are flat surfaces along the vertical direction. The formed peripheral wall portion is adopted. Also in this feeding part, by making the angle formed by the sides on both sides of the notch part close to a right angle, the surface corresponding to the notch part is aligned with the corner part of the glass water tank, and the corner part of the water tank is sandwiched. Each surface on both sides of the cutout portion can be sucked onto two continuous inner wall surfaces.

Further, in the present invention, the peripheral wall portion, which is the main part of the feeding tool, can be easily and inexpensively manufactured by bending a strip-shaped sheet made of plastic corrugated cardboard at a plurality of points in the length direction and joining both ends thereof.

The feeding tool of the present invention can float naturally on the water surface of the aquarium without using parts such as suction cups, hooks, and floats, can be easily attached to the inner wall surface of the aquarium, and can be easily removed. be. Therefore, the convenience can be significantly improved as compared with the conventional feeding tool.

FIG. 1 shows an embodiment of a feeding device 1 for ornamental fish to which the present invention is applied.
The feeding tool 1 of this embodiment is a hollow member made of a peripheral wall portion 10 having a triangular outer peripheral shape. The three surfaces 10a, 10b, 10c of the outer peripheral portion of the peripheral wall portion 10 and each surface on the inner peripheral side facing them are all flat surfaces along the vertical direction. The two surfaces 11 and 12 formed by the upper and lower edges of the peripheral wall portion 10 are opened together, the upper opening surface 11 functions as a feeding port for feeding food, and the lower opening surface 12 feeds fish. Functions as a feeding port for feeding. The peripheral wall portion 10 functions as a guard to prevent the introduced bait from spreading.

In FIG. 1, each opening surface is represented by different reference numerals 11 and 12 for convenience, but the sizes and shapes of these surfaces 11 and 12 may be the same, and the vertical relationship may be reversed.

As described above, the feeding tool 1 of this embodiment is composed of only the member serving as the peripheral wall portion 10. Since the peripheral wall portion 10 needs to be lightweight and strong enough not to be deformed even in water, plastic corrugated cardboard is used as the material of the peripheral wall portion 10 in this embodiment.

By using a plastic corrugated cardboard that contains a layer of air inside and has appropriate mechanical strength, the peripheral wall portion 10 of this embodiment has strength enough not to be deformed even in water and is naturally thrown into water. It will be something that emerges.

FIG. 2 shows a method of manufacturing the peripheral wall portion 10.
The peripheral wall portion 10 of this embodiment is formed by bending a strip-shaped sheet S (shown by a plan view and a front view) made of plastic corrugated cardboard at two points in the length direction and joining both ends with an adhesive. It should be noted that thin-walled portions ts, which serve as a glue margin required for joining, are provided at both ends of the strip-shaped sheet S. However, the joining of both ends of the strip-shaped sheet S is not limited to the adhesive, but can also be performed by welding.

A plastic corrugated cardboard with a flat surface and light weight can be attracted to the glass surface by the surface tension of water up to a certain size. Focusing on this characteristic and the above-mentioned buoyancy, in this embodiment, water is used from the bottom of the peripheral wall portion 10 to an intermediate position in the height direction (for example, a height position of about 1/3 to 2/3 of the whole). It is possible to maintain the state in which the portion above the water surface is exposed to the water surface by immersing the water tank 2 (see FIG. 6), and the outer wall surface of the peripheral wall portion 10 is brought into contact with the inner wall surface of the water tank 2 (see FIG. 6) containing water. The size of the peripheral wall portion 10 is adjusted so that the entire feeding tool 1 can be fixed to one place of the water tank 2 by sucking it onto the inner wall surface of the water tank 2 and using only the suction force thereof. Further, the height of the peripheral wall portion 10 is adjusted in consideration of the original function of preventing the outflow of food.

Specifically, the inventor adjusts the width of each surface of the peripheral wall portion 10 (corresponding to the side of the triangle) in the range of about 7 to 18 cm using a plastic corrugated cardboard having a thickness of about 2.5 mm, and the peripheral wall portion 10 It has been confirmed that the feeding tool 1 satisfying the above conditions can be manufactured by setting the height of the cardboard to about 2 cm.

Incidentally, what can be sucked onto the inner wall surface of the water tank 2 by the adsorption force of water is not limited to plastic corrugated cardboard, but also plastic films and waterproofed paper pieces. However, even if the peripheral wall portion 10 is made of these materials, it is difficult to float the peripheral wall portion 10 on the water surface while maintaining its posture and external shape.

However, other than plastic corrugated cardboard, it has buoyancy that allows it to float on the water surface with the part above the intermediate position in the height direction exposed above the water surface, and has enough strength to prevent the peripheral wall portion 10 from being deformed even in water. Any material that can be attached to the inner wall surface of the water tank 2 by the surface tension of water can be used to form the peripheral wall portion 10 having the same function as described above. In that case, only the outer surface of the peripheral wall portion 10 may be a flat surface along the vertical direction, and the inner surface side may be a curved surface or a rough surface.

The feeding tool 1 shown in FIG. 1 is assumed to be arranged at a corner portion of the water tank 2, and the outer peripheral shape of the peripheral wall portion 10 is set to a shape close to a right triangle. However, the shape of the peripheral wall portion 10 is not limited to this, and the peripheral wall portion 10A having a square outer peripheral shape as shown in FIG. 3 may be adopted. Alternatively, as shown in FIGS. 4A to 4D, right-angled triangular or square peripheral wall portions 10B, 10C, 10D, 10E having notches formed at one or more corners may be adopted. .. By manufacturing the peripheral wall portion of each example by the same method as shown in FIG. 2, each of the inner and outer surfaces can be made into a flat surface along the vertical direction.

If the entire feeding tool 1 can be supported by sucking one flat surface to the inner wall surface of the water tank, the outer peripheral shape of the peripheral wall portion may be a triangle other than a right triangle, or may be rectangular. May be good. Alternatively, it may be a pentagon or a hexagon consisting of only sides longer than the notched portion in FIGS. 4 (b) and 4 (c). Alternatively, as shown in FIGS. 5A and 5B, the peripheral wall portions 10F and 10G having a semicircular or fan-shaped outer peripheral shape are used so that the flat surface of the outer peripheral portion is attracted to the inner wall surface of the water tank 2. You can do it.

The feeding tool 1 shown in FIG. 1 is composed of only the peripheral wall portion 10, but the present invention is not limited to this, and even if a lid piece having a through hole of a predetermined size is joined to the upper and lower opening surfaces 11 and 12. good. In this way, the feeding port can be made into a size suitable for feeding by the lid piece on the bottom side. Further, by catching the bait that has started to fall after being diffused to the side of the peripheral wall portion 10 with the lid piece, it is possible to reduce the bait that sinks to the bottom of the aquarium without entering the mouth of the fish.
The same lid pieces as above can be provided on the upper and lower opening surfaces of the feeding tool having the peripheral wall portions 10A to 10G of another example shown in FIGS. 3 to 5. In any feeding tool, the place where the lid piece is provided may be limited to the lower opening surface.

FIG. 6 shows a state in which the feeding tool 1 shown in FIG. 1 is attached to the water tank 2 for feeding. When the feeding tool 1 is thrown into the water tank 2 by the above-mentioned buoyancy, the portion above the intermediate position in the height direction is naturally maintained in a state of being above the water surface 3 and floats on the water surface 3. Even if the water level changes due to the addition of water to the water tank 2 after that, the feeder 1 keeps the same posture and continues to float on the water surface 3. When the user pushes the floating feeding tool 1 with a finger or the like to bring it close to the inner wall surface of the water tank 2, any surface of the peripheral wall portion 10 can be sucked to an appropriate position on the inner wall surface of the water tank 2.

In the feeding tool 1 of this embodiment, since the outer peripheral shape of the peripheral wall portion 10 is set to a shape close to a right triangle, the corner portion close to the right angle is formed at the joint portion (layer such as adhesive) of the two glasses of the water tank 2. By following the formed portion), the two surfaces 10a and 10b connected to each other with the corner portion interposed therebetween can be attracted to the glass surface, respectively. As a result, two of the three outer surfaces of the peripheral wall portion 10 can be sucked onto the inner wall surface of the water tank 2, so that the entire feeding tool 1 is stably supported at one place inside the water tank 2. be able to. Further, even when the feeding tool 1 is taken out, the suction state between the surfaces 10a and 10b and the water tank 2 can be easily released by pulling the peripheral wall portion 10 away from the inner wall surface of the water tank 2.

Furthermore, due to the buoyancy that can maintain the state where the bottom to the middle position in the height direction is immersed in water and the part above it is above the water surface, and the strength that the peripheral wall portion 10 does not deform even in water, The bait put in from the feeding port (upper opening surface 11) can be kept in the range surrounded by the peripheral wall portion 10, and the fish is attracted to the feeding port (lower opening surface 12) for efficient feeding. It can be carried out.

When the feeding tool 1 having the square peripheral wall portion 10A shown in FIG. 3 is used, any combination of two surfaces connected with the corner portion sandwiched between them is adsorbed on the corner portion of the water tank 2. It is possible to make it, and it is not necessary to worry about the orientation of the feeding unit 1.

When the feeder 1 with the right-angled triangular or square peripheral wall portions 10B, 10C, 10D, 10E having notches formed at the corners shown in FIG. 4 is used, the notched portions of the peripheral wall portions 10B to 10E are used. By aligning the surface 15 corresponding to the surface 15 along the joint portion of the glass of the water tank 2 and sucking the surfaces on both sides of the surface 15 to the glass surface, the attachment of the feeding tool 1 to the water tank 2 can be more stable. .. Further, in the water tank manufactured by bending the glass, the surfaces 15 on both sides of the surface 15 are formed by aligning the surface 15 corresponding to the notch portion of the feeding tool 1 by the peripheral wall portions 10B to 10E along the curved surface of the corner portion. Each can be sucked onto the glass surface connected to the corner.

Up to this point, the description has been made on the premise that the water tank 2 to which the feeding tool 1 is mounted has a wall plate made of a glass plate, but even in a water tank whose wall portion is made of plastic, the peripheral wall is similarly affected by the surface tension of water. The portion 10 is attracted to the inner wall surface of the water tank, and the feeding tool 1 can be stably supported at one place in the water tank by the suction force thereof.
