COATING OF PET ANIMAL TOILET TRAY Russian patent published in 2014 - IPC A01K23/00 

FIELD: personal use articles.

SUBSTANCE: coating of pet animal toilet tray contains a base designed in the form of a flexible film sheet. Positioned on the base are multiple detachable flexible film layers, in the central part whereof multiple through holes are made. The holes are arranged chequerwise. Positioned on the open surface of the detachable sheet most remote from the base are multiple fixing plates made of flexible tape. Each fixing plate is connected to the base via matched through holes. Each fixing plate is connected immediately to the base by means of spot welding with welding spots formation. The ratio of the diameter of each matched hole to that of a welding spot is 1:0.25÷0.75. The ration of the fixing plate thickness to the welding spot diameter is 1:1.8÷5.5. The ratio of the thickness of the base to that of the fixing plate is 1:2.3÷2.5. The ratio of the fixing plate thickness to the maximum total thickness of all the detachable sheets is 1:1.8.

EFFECT: ensuring protection against liquid leakage from the top detachable layer to the underlying layers and the base as well as the said coating manufacture process simplification.
