Method and Apparatus for Providing Seaweed Food in an Aquarium

Abstract

A seaweed aquarium feeder and method allows fish to feed on seaweed food while preventing escape of the food into aquarium water. The feeder includes a base and hinged lid which closes against the base. The lid includes a rectangular recessed seaweed holding windowed area which fits over a protruding rectangular platform of the base. Seaweed food is cut or folded into rectangular sheets captured between the recessed seaweed holding windowed area of the lid and the protruding platform of the base. Windows in the lid allow the fish access to the seaweed food while covering edges of the folded or cut seaweed to prevent tearing off pieces of pieces of the seaweed which may clog an aquarium filter. A magnet pocket in the base holds a first magnet the feeder is held against an aquarium wall by cooperation of the first magnet with a second magnet outside the aquarium.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.

[0024] Where the terms about or generally are associated with an element of the invention, it is intended to describe a feature's appearance to the human eye or human perception, and not a precise measurement. The term horizontal refers to the plane the feeder primarily resides in against an aquarium wall and the term vertical refers to dimensions generally perpendicular to the horizontal. A substantially rectangular closed perimeter refers to a rectangular wall which may include rounded corners. The feeder is preferably made from plastic or a similar material, and surfaces are not precisely horizontal or vertical, given manufacturing tolerances, but generally appear to be horizontal and vertical within the above definition.

[0025] An aquarium 10 with an improved aquarium feeder 60 according to the present invention is shown in FIG. 1. The seaweed feeder 60 is held against an aquarium wall 10a below an aquarium water line 11, and holds seaweed (see FIG. 5) 16 accessible to fish 14 through windows 10 (see FIG. 2A).

[0026] A top perspective view of a seaweed feeder 60 is shown in FIG. 2A and a bottom perspective view of a seaweed feeder 60 is shown in FIG. 2B. The seaweed feeder 60 includes a base 66 having a generally horizontal and flat base flange 67 surrounding a generally rectangular (may have rounded edges and corners) protruding platform 72 extending generally perpendicularly out of the base flange 67, and a magnet pocket 68. The protruding platform 72 preferably has a solid face 73 (i.e., no openings) residing parallel to the base flange 67. A base wall 77 connects the solid face 73 to the base flange 67. The base wall 77 is generally perpendicular to the solid face 73 and to the base flange 67.

[0027] A lid 62 is connected to the base 66 by a hinge 64. The lid 62 includes a generally flat and horizontal lid flange 63 surrounding a generally rectangular recessed windowed area 74 receding from the lid flange 63 and residing in a plane generally parallel with the lid flange 63. The windowed area 74 includes a multiplicity of windows 70, for example, between 12 and 40 windows 70 in between six and ten rows and two and four columns and preferably 24 windows 70 in eight rows and three columns. A lid wall 75 is generally perpendicular to both the lid flange 63 and the windowed area 74 and connects the recessed windowed area 74 to the lid flange 63. The lid wall 75 is generally parallel to the base wall 77 when the lid 62 is closed over the base 66 the lid wall 75 and base wall 77 provide an interference fit to retain the lid 62 on the base 66.

[0028] A top view of the seaweed feeder 60 is shown in FIG. 3, a cross-sectional view of the seaweed feeder 60 taken along line 20-20 of FIG. 3 is shown in FIG. 4A, and a cross-sectional view of the seaweed feeder 60 with a closed cover is shown in FIG. 4B. The seaweed feeder 60 has an overall length L1 of preferably 313 mm. The base 66 has a length L2 of preferably about 179 mm, and the lid 62 has a length L3 of preferably about 134 mm. The base 66 and lid 62 preferably have a width W1 of preferably about 68 mm. The base 66 has a height H3 of preferably between 7 mm and 10 mm and more preferably about 7.8 mm and the lid 62 has a height H4 of preferably between 7 mm and 10 mm and more preferably about 7.5 mm. The windows have a length L4 of preferably between 6 mm and 14 mm and more preferably about 10 mm, and a width W2 of preferably between 6 mm and 16 mm and more preferably about 12 mm. When the lid 62 is closed, a gap G is created between the recessed windowed area 74 and the protruding platform 72 for the seaweed food 16. The gap G may vary and conforms to the thickness of the seaweed sheet 16 (see FIG. 5).

[0029] The seaweed feeder 60 is shown capturing a substantially rectangular sheet of seaweed 16 between the base 66 and lid 62 in FIG. 5 and a top view of the seaweed feeder 60 is shown closed and containing the sheet of seaweed 16 in FIG. 6. The sheet of seaweed 16 is not necessarily perfectly rectangular but is sufficiently rectangular and edges 16a sufficiently straight, so that none of the edges 16a of the seaweed 16 are exposed through the windows 70 of the lid 61. A magnet 78a resides in the magnet pocket 68 (see FIG. 2), and the seaweed feeder 60 may be held to the aquarium 10 wall (see FIG. 10) by a cooperating magnet 78b the exterior of the aquarium.

[0030] A method according to the present invention is described in FIG. 7. The seaweed food is cut or folded into substantially rectangular seaweed sheets at step 100. The aquarium seaweed feeder is opened at step 102. The rectangular seaweed sheets are positioned over a platform projecting out from a base of the aquarium seaweed feeder at step 104. A windowed lid is closed over the rectangular seaweed sheets and over the platform at step 106. The aquarium seaweed feeder is positioned below an aquarium water line in an aquarium at step 108.

[0031] The seaweed feeder 60 is preferably made from plastic, and more preferably from Polyvinyl Chloride (PVC) or Acrylonitrile Butadiene Styrene (ABS) and most preferably from ABS.

[0032] While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
