Abstract

An anti-splash sanitary urinal screen has components including a flat base, an outer cup, an inner cup and a mesh screen. The flat base has a lattice work permitting the passage of liquid through it and defining assembly slots that are used to hold the components together. The outer cup flexes when squeezed, allowing tabs to pass through the assembly slots to lock the components together. The outer cup has a first open window through a domed area of the cup. The inner cup has a second open window of approximately the same size. The inner cup has a shape conforming to the outer cup such that the inner cup fits within the outer cup so that they may be nested together with the windows aligned. The mesh screen fills the space between the outer cup and the inner cup so that liquid may flow through the windows and screen.

Claims

1. An anti-splash sanitary urinal screen comprising:

a flat base defining a lattice work permitting passage of liquid therethrough and further defining a plurality of assembly slots;

an outer cup comprising a bottom portion;

a top portion; and

a plurality of tabs extending from the bottom portion, each tab in the plurality of tabs being insertable into one of the assembly slots in the plurality of assembly slots so as to detachably secure the outer cup to the flat base;

the bottom portion comprising an open cross-section;

the top portion consisting of a domed hemisphere having a solid surface that defines a first open window through the domed hemisphere, the first open window having a triangular shape with a vertex near the top of the domed hemisphere, the solid surface having no other penetration therethrough;

an inner cup, the inner cup having a shape conforming to the outer cup such that the inner cup fits within the outer cup so that they may be nested together;

the inner cup defining a second open window that is approximately coextensive with the first open window, the inner cup configured to snap together with the outer cup when nested in the outer cup;

a mesh screen filling the space between the first open window and the second open window;

the outer cup further comprising a ridge arm located inside the domed hemisphere, the ridge arm configured to engage the mesh screen during assembly; and

wherein when the inner cup and the mesh screen are nested within the outer cup, then the first open window and the second open window align to allow liquid to pass through the first open window through the mesh screen and thence through the second open window.

2. An anti-splash sanitary urinal screen comprising:

a flat base defining a lattice work permitting passage of liquid therethrough and further defining a plurality of assembly slots;

an outer cup comprising a bottom portion;

a top portion; and

a plurality of tabs extending from the bottom portion, each tab in the plurality of tabs being insertable into one of the assembly slots in the plurality of assembly slots so as to detachably secure the outer cup to the flat base;

the bottom portion comprising an open cross-section;

the top portion comprising a domed hemisphere defining a solid surface;

the outer cup further defining a first open window through the domed hemisphere with having no other penetration through the solid surface;

an inner cup, the inner cup having a shape conforming to the outer cup such that the inner cup fits within the outer cup so that they may be nested together;

the inner cup defining a second open window that is approximately coextensive with the first open window, the inner cup configured to snap together with the outer cup when nested in the outer cup;

a mesh screen covering the first open window;

the outer cup further comprising a ridge arm located inside the domed hemisphere, the ridge arm configured to engage the mesh screen during assembly; and

wherein when the inner cup and the mesh screen are nested within the outer cup, then the first open window and the second open window align to allow water to flow through the first open window through the mesh screen and thence through the second open window.
