BIO-BAG WITH PERFORATION FOR KITCHEN SINK Russian patent published in 2019 - IPC A47J47/20 

FIELD: satisfaction of human vital needs.

SUBSTANCE: biometric bag with perforation for kitchen sink comprises two side walls of film, fixed in lower and lateral parts between each other and has on edges of open part of two projections on each of side walls, wherein lateral sides of each of the projections are made curved lines of the sinusoid in a given range of angles from -1/2π up to 1/2π on one side and 1/2π up to 3/2π on the other side, smoothly changing into the line of the open part edge, and the front side has a rounded convex outline smoothly changing into curved lines of the sinusoid, and the height and width of the protrusions are selected from given ratios, the micro perforation different from the micro to the macro diameter and the stiffness ribs, wherein the perforation is made with a gradient density from the attached lower part and / or the bottom base to reduce, and the diameter is increased by the middle to approximately 1/3 of the length and / or height of the bag, wherein the length and / or height of the bag is calculated from given ratios, e.g. 1/3 of the standard depth – fine, medium, deep sinks of kitchen sinks, wherein height h of protrusions is selected from ratio h=(X-Y)⋅D, and width S of ledges is selected from ratios S=(Z-k)⋅D, where D is the diameter of the open part of the bag is always greater than the diameter of the kitchen sink sinks regardless of their shape and size, pre-wetted with water for more sticking to the bag walls sticking to them, film of which has a corresponding operational density and / or strength of biopolymers and has a greenish-lime tone, and the stiffening ribs are made in the form of a plurality of differently directed folds by a man-made method by compression and / or grinding of the entire bag.

EFFECT: bio-bag with perforation for kitchen sink is a disposable device for prevention of ingress of food wastes into system of drainage of kitchen sink sinks, as well as hygienic collection thereof with subsequent house recycling, as well as specified self-utilization in the environment.
