Disclosed is a bottle trap having a main body having an open end coupled to a tailpiece pipe and a tapered closed end having at least one face inclined at a first angle with respect to axis of the main body. The bottle trap also includes a cylindrical trap element received on the open end and extending axially into the main body up to at least half the length of the main body. An outlet orifice is configured on peripheral surface of the main body perpendicularly thereto. The outlet orifice is adapted to be coupled to a horizontal drain pipe. Also, a thread-less coupling is configured at the open end and outlet orifice, respectively, for connecting the tailpiece pipe and the drain pipe, respectively, thereto for ensuring a leak-proof coupling. Moreover, at least one sealable drain orifice is configured at the at least one inclined face of the tapered closed end.

An odor-trap device (1) for in particular flushing-water-free sanitary devices, for example urinals, comprises an outflow element (2) with a sealing wall (3), and also comprises a sealing membrane (4), which is in sealing contact with the sealing wall (3) in a closure position and, in the presence of a liquid, such as urine, is pushed away from the sealing wall (3) from the closure position into an open position, as a result of which a gap (19) is formed between the sealing membrane (4) and sealing wall (3), it being possible for the liquid to be led away through said gap, and further comprises a mounting element (5) for mounting the sealing membrane (4) in relation to the sealing wall (3). The odor-trap device (1) is characterized in that the seating membrane (4) has a seating surface (6) which runs substantially parallel to the sealing wall (3), wherein the sealing surface (6) butts against the sealing wall (3) substantially with surface-area contact, or wherein the sealing surface (6) is spaced apart from the sealing wall (3) such that the liquid film which is present, at least in part, between the sealing wall (3) and the sealing surface (6) provides a force of adhesion between the sealing wall (3) and seating surface (6).

A drain assembly for a sink has an abutment surface (14) for abutting an underside of the sink around the drain aperture, and a first wall portion (16) circumscribing an upper drain volume (18). A down-flow conduit (20) and an up-flow conduit (24) are delineated by a second and third wall portions (22, 26), one of which has an edge defining a lip (28) between the down-flow conduit (20) and up-flow conduit (24). An outlet (30) is connected to up-flow conduit (24). A removable lower cover (32) attaches to the wall portions so as to complete a flow path from the down-flow conduit (20) to the up-flow conduit (24) so as to form a trap. At least the first, second and third wall portions (16, 22, 26) and the outlet (30) are integrally formed as a unitary body, most preferably by an injection molding process.

A multi-layer water sealing device, includes at least two layers of water seal sequentially arranged from top to bottom. An upper-layer water seal has a floating bell-shaped cover structure, and the floating bell-shaped cover structure includes a water sealing box and a floating bell-shaped cover arranged in the water sealing box. A lower-layer water seal is arranged in a drain pipe below the floating bell-shaped cover, and one side of the water sealing box is extended to form or connected to a communication cavity offset from the drain pipe. The floating bell-shaped cover correspondingly is extended to form or connected to a floating component floatable in the communication cavity and offset from the drain pipe.

A siphon includes a bypass. The siphon includes an upper section having a top coupling for connecting to a drain outlet and a side drain opening having coupling for connecting to a wastewater utility pipe. The siphon upper section is facilitates direct flow via the side drain opening, thereby to bypassing a basin of the siphon. Thus, substantial volume of accumulated water is evacuating directly into the wastewater utility pipe.

The present invention relates to a trap integrated drain device for a washbasin, which includes: an upper fastener having a ring shape in a horizontal direction, having a drainpipe penetration hole punched in a central portion thereof so as to be insert-coupled to an outer circumference of a drainpipe that protrudes downward by penetrating a lower protrusion part of the washbasin, and including a plurality of close-contacting protrusions radially protruding from a top surface thereof; a sealing packing having a ring shape, insert-coupled to the outer circumference of the drainpipe, and disposed on the top surface of the upper fastener to come into close contact with a bottom surface of the lower protrusion part of the washbasin by the close-contacting protrusions so that watertightness is maintained; a tightening nut disposed on the bottom surface of the upper fastener and screw-coupled to a male screw part of the drainpipe to allow the upper fastener and the sealing packing to be fixed and coupled to the bottom surface of the lower protrusion part of the washbasin; a barrel-shaped trap casing, of which an upper portion is opened and screw-coupled to the upper fastener, including an outlet connected to a lower pipe at a lower portion thereof to protrude downward; and a barrel-shaped trap member, of which an upper portion is opened, including a plurality of mounting protrusions that radially protrude from an outer circumferential surface of an upper portion thereof so as to be mounted on a stepped portion disposed on an inner circumferential surface of the trap casing and installed movable in a vertical direction, wherein a lower portion of the drainpipe is disposed inside the trap member through the opened upper portion of the trap member.

A drain trap includes an outer part including a circumferential wall, the outer part extending in an axial direction between an outer part upper end and an outer part lower end, the outer part including outer part radial threads proximate the outer part upper end, the outer part lower end forming a well configured to trap and retain fluid, the outer part further including at least one opening disposed in the circumferential wall, an inner part, and a flat disk structure retained within the well. Fluid entering the drain trap accumulates in the well, and the fluid entering the drain trap is expelled from the drain trap through the at least one opening disposed in the circumferential wall.
