DETAILED DESCRIPTION

[0018] A design and method for using a pipe cap 100 is provided. A pipe cap 100 is designed for use in water drainage systems used, at least, in residential and commercial buildings. The pipe cap can have a main body 101 having a first end 103 and a second end 105. The main body 101 can have an elongated shape. The main body 101 can have a shape generally or exactly reflecting a cylinder, a rectangular prism, a cube, a pyramid, a cone, a hexagonal prism, a hexagonal cone, and/or a sphere.

[0019] The pipe cap 100 can include a face 107 disposed about the first end 103. The first end 103 and/or the face 107 can include one or more openings 111. The one or more openings 111 can otherwise be referred to as “hole(s)” when appropriate. The opening 111 can vary in size and shape. For example, the opening 111 can be square, circular, rectangular, triangular, or any combination thereof. In another example, the one or more openings 111 can be circular in shape having a diameter of about 1 millimeter, about 2 millimeters, about 3 millimeters, about 4 millimeters, about 5 millimeters, about 6 millimeters, about 7 millimeters, about 8 millimeters, about 9 millimeters, or about 10 millimeters. In another example, the opening can have a diameter of about 1 inch, about 2 inches, about 3 inches, about 4 inches, about 5 inches, about 6 inches, about 7 inches, about 8 inches, about 9 inches, or about 10 inches.

[0020] The pipe cap 100 can include one or more openings 111, two or more openings 111, three or more openings 111, four or more openings 111, five or more openings 111, six or more openings 111, seven or more openings 111, eight or more openings 111, nine or more openings 111, ten or more openings 111, eleven or more openings 111, twelve or more openings 111, thirteen or more openings 111, fourteen or more openings 111, fifteen or more openings 111, sixteen or more openings 111, or seventeen or more openings 111.

[0021] In one or more embodiments, the face 107 can include a pattern of one or more openings 111 sufficient to prevent solid objects from traveling through the openings 111. Accordingly, the size of the one or more openings 111 can be varied for the prevention of these solid objects from passing through the face 107 and/or the first end 103. For example, the openings 111 can be sized to allow small grains of sand to pass through but block the passage of pebbles and/or rocks. In another example, the one or more openings 111 can be sized to allow a flea to pass through but block the passage of a dirt-dauber or wasp.

[0022] The one or more openings 111 can be disposed through the main body 101 of the pipe cap 100. The one or more openings 111 can be disposed through the walls of the main body 101 at or about the first end 103, at or about the second end 105, at or about the face 107, or any combination thereof. For example, as shown in FIG. 8, the one or more openings 111 can be disposed through the walls of the main body 101 at or near the first end 103 of the pipe cap 100.

[0023] As shown in FIG. 2, a pipe cap 200 can include a main body 201 having a first end 203 and a second end 205, and the second end 205 of the pipe cap 200 can be configured to connect to a pipe or piping structure. The pipe cap 200 can include a face 207 disposed at or about the first end 203, and one or more openings can be disposed therethrough.

[0024] The main body 201 can include a connector 223 disposed about the second end 205 of the main body 201. The connector 223 can be configured to connect or otherwise attach the pipe cap 200 to a drain pipe (not shown). The connector 223 can be a threaded and/or “male” connector configured to connect to a threaded and/or “female” receptacle. Alternatively, the connector 223 can be a threaded and/or female receptacle configured to connect to a threaded and/or “male” connector. One or more ridges 209 can be disposed on the main body 201 of the pipe cap 200 to allow a user to more easily handle the pipe cap 200.

[0025] FIG. 3 depicts a front side view of a pipe cap 300. One or more openings 311 can be disposed on a face 307 of the pipe cap. As shown, the openings 311 can be collectively arranged in a circular pattern on the face 307 of the pipe cap 300.

[0026] As shown in FIGS. 4A and 4B, at least one embodiment of a pipe cap 400 can be threadably connected to or otherwise attached to a conduit 431. Specifically, the pipe cap 400 can be connected to the conduit 431 by axially rotating the pipe cap 400 such that the threads of the pipe cap connector 423 interlock with the threads of the conduit 431. The conduit 431 can include a flange 435 having a channel 437 disposed therethrough. In at least one embodiment, the channel 437 can include a hole disposed through the flange 435, including a hole disposed through the flange 435 at the center of the flange 435. In at least one other embodiment, the channel 437 can include a piece of tubing or pipe extending outward from the flange 435, and such protruding piece can be configured to attached or connect to the pipe cap 400 (as shown in FIGS. 4A-4B). A portion of the channel 437 can be threaded, glued, or otherwise permanently or temporarily attached to the pipe cap 400.

[0027] Drainage pipes are often found protruding through an outer wall of a building or structure. Most common, such a drainage pipe protrudes from the side of the building or from an overhang portion of a roof by several inches, so that fluid may drain out of the building without causing damage or staining to the outer wall of the building. In some situations, though, the water drainage pipe is flush with the side of the building or overhang portion of the roof, wherein the pipe cap can be attached to the drainage pipe at a position interior to the outer wall. In some circumstances, it may be more beneficial to connect an extension conduit onto the drainage pipe and then connect the pipe cap to the extension conduit. In some circumstances, the drainage pipe may not be threaded and configured to connect to a threaded connector on the pipe cap. To remedy this, a conduit may be used, attaching a first end of the conduit to the drain pipe and attaching a second end of the conduit that is threaded to the threaded connector of the pipe cap.

[0028] As shown in FIG. 5, the pipe cap 500 can be configured to attach to the conduit 531 having a flange 533, and the conduit 531 can be configured to attach to the drainage pipe 545. In this configuration, and those like it, the flange 533 of the conduit 531 can be used to secure and stabilize the pipe cap 500. For example, the flange 533 can be secured to the overhang 503 portion of a roof 501 by nailing, screwing, or otherwise securing the flange 533 to the overhang 503. The conduit 531 can include a flange 533 having a channel 535 disposed therethrough.

[0029] FIG. 6 depicts an adapter conduit 641 used to attach the pipe cap 600 to the terminal end of the drainage pipe 645. The drainage pipe 645 can protrude from the overhang 603 of a roof 601 (as shown). It is not always the case that the end of the drainage pipe is configured to attach to the pipe cap. For example, the connector of the pipe cap 600 may be of a different size or configuration than the end of the drainage pipe. In such cases, an adapter conduit 641, can be used to connect the pipe cap 600 to the drainage pipe 645.

[0030] As shown in FIG. 7, one or more drainage pipes 745, 747 can protrude from a building structure at the overhang 703 of a roof 701 and/or through a side wall 705 of the building structure. A first pipe cap 700 can be connected or otherwise attached directly to a first drainage pipe 745 that is protruding from the overhang 703 portion of a roof 701. A second pipe cap 710 can be connected or otherwise attached directly to a second drainage pipe 747 protruding from the sidewall 705 of the building structure.

[0031] FIG. 8 depicts a side view of an alternative embodiment of a pipe cap 800. One or more openings 811a, 811b can be disposed through the walls of the pipe cap 800. As shown in FIG. 8, one or more openings 811b can be disposed through the side walls or main body 801 of the pipe cap 800 and one or more openings 811a can be disposed through the face 807 of the pipe cap 800. The openings 811a, 811b can be elongated in shape. The openings 811a, 811b can vary in shape from one another. The openings 811a, 811b can be configured to allow maximum drainage through the pipe cap 800 while adequately preventing insects and rodents from passing through the openings 811a, 811b.

[0032] FIG. 9 depicts a cross-section view of a pipe cap 900 disposed on a drainage pipe 945. A method for using the pipe cap 900 can include connecting to or otherwise disposing on to the drainage pipe 945 by tightly fitting the pipe cap 900 onto the drainage pipe 945. In at least one other embodiment, the pipe cap 900 can be connected to the drainage pipe 945 via glue, paste, rubber cement, PVC adhesive, or any other adhesive. Once the pipe cap 900 is connected to the drainage pipe 945, fluid (eg., condensate fluid, water) can be directed from the condenser coils of an HVAC system, through the drainage pipe 945, and then through the pipe cap 900. The pipe cap 900, by way of the openings 911 disposed through a portion thereof, can be used to prevent large solid items from passing into and/or out of the drain pipe 945.

[0033] The piping cap can be made of copper, steel, polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), or acrylonitrile butadiene styrene (ABS), carbon steel (galvanized or non-galvanized), impact tested carbon steel, low temperature services carbon steel, stainless steel, malleable iron, non-ferrous metals, non-metallic composites (e.g., ABS, fiber-reinforced plastic (FRP), PVC, HDPE, tempered glass), alloy steel, a variety of plastic composites, or any combination thereof.

[0034] Certain embodiments and features have been described using a set of numerical upper limits and a set of numerical lower limits. It should be appreciated that ranges from any lower limit to any upper limit are contemplated unless otherwise indicated. Certain lower limits, upper limits and ranges may appear in one or more claims below.
