Tamper evident bottle finish and cap assembly

An assembly of a bottle neck finish capped by an aggregate reusable cap comprising:

• a bottle neck finish having,
• a top round lip with a cross-section that transitions inwards down into a bulge and then a curved recess to ease the flow of content and to act as a tight boundary when interacting with the constricting surface of a cap;
• thread lugs disposed at equal intervals a distance below the lip on the inner vertical surface of said finish that may constitute a clockwise downwards winding female thread that allows for the easy flow of content;
• equally space quadrant-sphere indentations disposed inferiorly to the lip on the outwards sloping outer surface of said finish;
• a jutting spherical-shaped protrusion marker on its outer surface at the top of the neck and disposed aligned with one of the said indentations that is nearest the top thread lug on the inner surface of the neck;
• an aggregate reusable bottle cap that can tightly cap said neck finish in a manner that incorporates tamper evident functionality and that comprises of:
• an inner cap of cylindrical form closed at its bottom end with a male thread on its lower outer surface that may directly interact with said neck finish, said inner cap including equally spaced flaps extending from its top on the outermost surface, said inner cap including a thin circumferential flap disposed under an overhang cross-section at its top, said inner cap including flexible arc-cantilevers that partially form its top opening, said inner cap including equally spaced recesses disposed under the said flexible limbs, said inner cap including equally spaced wedge protrusions disposed on its inner vertical face below the said recesses;
• an outer cap composed of an inner and an outer cylindrical flange disposed on a flat circular top, said outer flange with outer surface comprising of equally spaced flutes and inferiorly to which a disposed spherical-shaped protrusion marker, said outer flange with a smooth inner surface that is punctuated by equally spaced recesses, wedges disposed on the undersurface of said circular top that extend from the recesses and point inwards to end at a small distance beyond the inner surface of said outer flange, equally spaced pairs of sloping wedges disposed on the underside of said circular top and on the outer connecting surface of said inner flange, equally spaced flexible arms with protruding wedges defined by apertures disposed near the top of said inner flange, equally spaced tracks defined by recesses on the outer face of said inner flange.
