1. A squeeze bottle comprising: a body having an end wall, side wall, and finished portion forming an inner cavity having an inner surface;a dispensing cap having a cap lid, a dispensing outlet, an exterior skirt, an interior skirt, an annular skirt, base wall, and a vent channel; an outlet valve arrangement;wherein the inner cavity contains a viscous liquid and includes a headspace positioned between the viscous liquid and the end wall;wherein the dispensing outlet, inner surface, interior skirt, annular skirt, and base wall are modified with an anti-adherence coating to reduce adhesion between the dispensing outlet, inner surface, interior skirt, annular skirt, base wall, and the viscous liquid;the anti-adherence coating is at least one of natural oils, silicone oils, or mineral oils;wherein the vent channel is positioned between the interior skirt and the annular skirt, such that replacement air drawn through the vent channel travels along the interior skirt and the inner cavity inner surface to the head space;wherein the vent channel comprises a vent having a check valve membrane; andwherein the check valve membrane allows replacement air to enter the vent channel and prevents viscous liquid from the inner cavity entering the vent channel. 2. The squeeze bottle of claim 1, wherein the cap lid comprises a vent plug. 3. The squeeze bottle of claim 1, wherein the outlet valve arrangement comprises an outlet valve having an outlet valve flap and an outlet valve retainer ring having an outlet valve retainer ring opening. 4. The squeeze bottle of claim 3, wherein the outlet valve flap is sectioned into two or more parts. 5. The squeeze bottle of claim 3, wherein the outlet valve retainer ring comprises a vent in fluid communication with at least one of the vent opening or the inner cavity. 6. The squeeze bottle of claim 3, wherein the outlet valve retainer ring opening is smaller in diameter than the outlet valve flap. 7. A squeeze bottle comprising: a body having an end wall, side wall, and finished portion forming an inner cavity having an inner surface;a dispensing cap having a cap lid, a dispensing outlet, an exterior skirt, an interior skirt, an annular skirt, base wall, and vent-channel;an outlet valve having an outlet valve flap and a flexible outlet valve retainer ring having an outlet valve retainer ring opening;wherein the inner cavity contains a viscous liquid and includes a headspace positioned between the viscous liquid and the end wall;wherein the dispensing outlet, inner surface, interior skirt, annular skirt, and base wall are modified with an anti-adherence coating to reduce adhesion between the dispensing outlet, inner surface, interior skirt, annular skirt, base wall, and the viscous liquid;the anti-adherence coating comprises a three-dimensional structure raised above the inner surface forming gaps with an impregnating liquid in and above the gaps;wherein the vent channel is positioned between the interior skirt and the annular skirt, such that replacement air drawn through the vent channel travels along the interior skirt and the inner cavity inner surface to the head space;wherein the vent channel comprises a vent having a check valve membrane; andwherein the check valve membrane allows replacement air to enter the vent channel and prevents viscous liquid from the inner cavity entering the vent channel. 8. The squeeze bottle of claim 7, wherein the flexible outlet valve retainer ring has a conical shape. 9. The squeeze bottle of claim 7, wherein the flexible outlet valve retainer ring is positioned under the outlet valve and around the annular skirt. 10. A method of dispensing a viscous liquid comprising: providing a squeeze bottle comprising: a body having an end wall, side wall, and finished portion forming an inner cavity having an inner surface;a dispensing cap having a cap lid, a dispensing outlet, an exterior skirt, an interior skirt, an annular skirt, base wall, and a vent channel having a check valve membrane;an outlet valve having an outlet valve flap and an outlet valve retainer ring having an outlet valve retainer ring opening; viscous liquid;wherein the inner cavity contains a viscous liquid and includes a headspace positioned between the viscous liquid and the end wall;wherein the dispensing outlet, inner surface, interior skirt, annular skirt, and base wall are modified with an anti-adherence coating to reduce adhesion between the dispensing outlet, inner surface, interior skirt, annular skirt, base wall and the viscous liquid;the anti-adherence coating is at least one of natural oils, silicone oils, mineral oils, or a three-dimensional structure raised above the inner surface forming gaps with an impregnating liquid in and above the gaps;applying pressure to the squeeze bottle to open the valve flap and dispense the viscous liquid;preventing the viscous liquid present in the inner cavity from entering the vent channel by the check valve membrane pressing against the outlet valve retainer ring and closing the vent channel;releasing the pressure and closing the valve flap; anddrawing replacement air through the vent channel and opening the check valve membrane allowing the replacement air to travel along the interior skirt and inner cavity inner surface to the head space. 11. The squeeze bottle of claim 1, wherein the interior skirt has an outer surface that is in contact with an inner surface of the finished portion.
