Abstract

The present disclosure relates to liquid dispensing products comprising spray dispensers and methods of using such products.

First claim

What is claimed is:

1 . A liquid spray product comprising a spray dispenser connected to a container containing a liquid pest control composition comprising:
a) from about 0.5% to about 12% by weight of the composition of sodium lauryl sulfate; b) from about 0.5% to about 15% by weight of the composition of an active ingredient selected from the group consisting of cornmint oil, peppermint oil, spearmint oil, rosemary oil, thyme oil, citronella oil, clove oil, cinnamon oil, cedarwood oil, garlic oil, geranium oil, lemongrass oil, eugenol, geraniol, 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, and c) from about 55% to about 90% by weight of the composition of water;
wherein the spray dispenser comprises a nozzle, a buffer system, and a pump;
wherein the nozzle comprises an outlet orifice, one or more swirl chambers, one or more vertical inlet ports, and one or more horizontal inlet ports, wherein the one or more vertical inlet ports are in fluid communication with the one or more horizontal inlet ports and the one or more horizontal inlet ports are in fluid communication with the one or more swirl chambers and the outlet orifice.

2 . The liquid spray product according to claim 1 , wherein the liquid pest control composition has a viscosity of from about 1 cps to about 500 cps.

3 . The liquid spray product according to claim 1 , wherein the liquid pest control composition has a surface tension ranging from about 10 mN/m to about 60 mN/m.

4 . The liquid spray product according to claim 1 , wherein the force to actuate the spray dispenser ranges from about 8 lb/pull to about 14 lb/pull.

5 . The liquid spray product according to claim 1 , wherein at 90 strokes/minute, the output volume is about 85% to about 99% of the output volume at 10 strokes/minute.

6 . The liquid spray product according to claim 1 , wherein the liquid spray product has a flow rate of about 0.5 g/pull to about 1.50 g/pull.

7 . The liquid spray product according to claim 1 , wherein the liquid pest control composition is formulated to provide a spray having a Sauter mean diameter of about 200 μm to about 500 μm.

8 . The liquid spray product according to claim 1 , wherein the liquid pest control composition is formulated to provide a spray having a D(90) of about 500 μm to about 850 μm.

9 . The liquid spray product according to claim 1 , wherein the ratio of the flow rate to the force to actuate is about 0.05 g/pound to about 0.2 g/pound.

10 . The liquid spray product according to claim 1 , wherein the liquid pest control composition comprises from about 0.1% to about 45% by weight of the composition of a solvent selected from the group consisting of isopropyl alcohol, triethyl citrate, isopropyl myristate, propylene carbonate, ethyl lactate, butyl lactate, butyl stearate, glycerin, and mixtures thereof.

11 . The liquid spray product according to claim 1 , wherein the liquid pest control composition comprises a pH adjusting agent selected from the group consisting of malic acid, citric acid, fumaric acid, humic acid, acetic acid, monosodium citrate, sodium citrate, disodium citrate, trisodium citrate, trisodium citrate dehydrate, trisodium citrate pentahydrate, sodium acetate, and combinations thereof.

12 . The liquid spray product according to claim 1 , wherein the liquid pest control composition has a turbidity less than about 20 NTU.

13 . The liquid spray product according to claim 1 , wherein the liquid pest control composition has a b* value of about 0 to about 5.

14 . The liquid spray product according to claim 1 , wherein the liquid pest control composition has a pH of about 5.0 to about 9.0.

15 . The liquid spray product according to claim 1 , wherein the container is transparent or translucent.

16 . The liquid spray product according to claim 1 , wherein the liquid pest control composition is formulated to provide a spray having a D(50) value of about 200 μm to about 500 μm.

17 . A method of controlling a pest comprising:
a. providing the liquid spray product according to claim 1 , b. dispensing the liquid spray product at a target pest.
