Abstract
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 rounded 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.
Claims22
A drain trap comprising:
- 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;
- and
- an inner part extending in the axial direction between an inner part upper end and an inner part lower end, the inner part including inner part radial threads proximate the inner part upper end configured to engage with the outer part radial threads of the outer part to attach the inner part to the outer part, wherein the inner part upper end includes an upper opening and the inner part lower end includes a bottom opening such that fluid entering the inner part through the upper opening and leaving the inner part through the bottom opening is transferred into the well of the outer part when the inner part is attached to the outer part,
- wherein fluid entering the drain trap accumulates in the well, and wherein the fluid entering the drain trap is expelled from the drain trap through the at least one opening disposed in the circumferential wall, and
- wherein the outer part radial threads are external threads, and wherein the inner part radial threads are internal threads.
