Liquid dispensing system, components and features thereof, and methods of use thereof

A pesticide product comprising a pesticide composition contained within a bottle defining an interior volume, wherein the bottle is configured to affix to a liquid dispensing fixture adapted to spray the pesticide composition, wherein a spray wand is fluidly connected to the liquid dispensing fixture, wherein the spray wand comprises a spray tube terminating at a spray nozzle, and wherein the spray nozzle is surrounded by a nozzle end structure having a radial dimension that is at least 150% of the outer diameter of the spray tube, and wherein the bottle comprises a neck terminating in a rim circumscribing and defining a main opening through the neck to the interior volume, a fluid passage fitting configured to fit over the rim or within the main opening of the bottle and fluidly connected to a draw tube disposed inside the bottle and extending from proximity of the main opening down to proximity of a bottom extent of the interior volume,

• wherein the fluid passage fitting comprises a vacuum relief port providing fluid communication between the interior volume and an outside environment, and a check valve structure operably associated with the vacuum relief port and configured to allow fluid to pass through the vacuum relief port into the interior volume and to restrict or prevent fluid from flowing through the vacuum relief port out of the interior volume,
• wherein the fluid passage fitting further comprises a fluid inhibiting element disposed on top of a liquid dispensing passage and configured to inhibit vertical expulsion of fluid through the liquid dispensing passage when the bottle is uncapped and squeezed,
• wherein the neck has an outer diameter of from about 35 mm to about 50 mm and comprises a first retaining feature outwardly radiating from the neck and engaged by a removeable cap, and a second retaining feature configured to be latchably engaged by the liquid dispensing fixture,
• wherein the removeable cap comprises a third retaining feature configured to latchably engage the liquid dispensing fixture that is geometrically identical to the second retaining feature,
• wherein the second retaining feature has a height of from about 1.25 mm to about 3 mm, radiates from about 3 mm to about 5 mm outwardly from the neck, and is disposed from about 15 mm to about 30 mm below the rim of the neck,
• wherein the pesticide composition comprises from about 0.1% to about 30% by weight of an active ingredient selected from the group consisting of peppermint oil, corn mint oil, spearmint oil, rosemary oil, thyme oil, citronella oil, clove oil, cinnamon oil, cedarwood oil, garlic oil, geranium oil, lemongrass oil, geraniol, eugenol, nerol, vanillin, 2-phenylethyl propionate, menthol, menthone, thymol, carvone, camphor, methyl salicylate, p-cymene, linalool, eucalyptol/1,8-cineole, alpha-pinene, bornyl acetate, gamma-terpinene, and mixtures thereof.
