A bottled particulate detergent is of certain particle sizes, bulk density and flowability and is contained in a necked bottle in which the neck opening is sufficiently small as to allow ready sealing with screw caps conventionally employed to close bottles while also allowing pouring from the bottle of the particulate detergent of the described characteristics. The bottle also includes a relatively narrow, hollow handle section through which the particulate detergent will flow. Also disclosed is a method of easily filling such bottles with free flowing particulate detergent. In both dispensing and filling operations, due to the characteristic of the detergent composition and the bottle, flow surprisingly like that of a liquid is obtained.

1. A method for washing soiled laundry, which comprises: pouring into a container an effective amount of a bottled, free flowing particulate laundry detergent from a transparent bottle having a neck portion for dispensing detergent from the bottle; adding the effective amount of the particulate laundry detergent in the container to wash water containing the soiled laundry thereby forming a washing mixture; agitating the washing mixture until the soiled laundry is cleaned; the transparent bottle being made of a thin-walled synthetic organic polymeric plastic which is essentially moisture proof, the neck being located at the top of the bottle and having a passageway therethrough with a cross-sectional area of less than 40% of the average cross-sectional area of the bottle, wherein the neck passageway has a cross-sectional area of about from 2 to 40 sq. cm., the bottle being provided further with an integral hollow handle located on the side of the bottle, wherein the interior of the handle communicates with other interior portions of the bottle, and the handle has an internal cross-sectional area in the range of about 1 to 10 sq. cm., the neck being located nearer the side of the bottle opposite that of the handle; and the free-flowing particulate detergent in said bottle being pourable through the neck and handle and having a composition comprising from about 2 to 50% by weight of a synthetic organic detergent selected from the group consisting of nonionic detergents and mixtures of the nonionic detergents with anionic detergents, wherein said nonionic detergent is a normally tacky ethoxylated detergent, and from about 50 to 90% by weight of builders for the detergent, wherein the builders are selected from the group consisting of ion exchanging clays, organic builders and sodium salts of at least one of bicarbonates, borates, carbonates, phosphates, and silicates; the particles being sized such that at least 90% thereof pass through an 8 mesh screen and are retained on a 200 mesh screen (U.S. Sieve Series), are of a bulk density of at least 0.5 g/cc., are of a flowability sufficiently high so that the particulate detergent flows through the neck and handle of the bottle, and are substantially dust-free so that after pouring some of the composition from said bottle, the bottle and the contained volume above the level of the particulate detergent return to a transparent condition, and resealable cap for the neck portion. 2. A method for washing according to claim 1 wherein the neck passageway of the bottle has a cross-sectional area of about from 3 to 20 sq. cm., the organic detergent includes a normally tacky ethoxylated nonionic detergent in an amount of from about 5 to 30% by weight, the bulk density is about from 0.55 to 0.80 g/cc, and wherein the laundry detergent and the resealable cap are adapted so that the cap serves as the container and one to two capsful of particulate detergent will be sufficient for an ordinary washing machine load. 3. A method for washing according to claim 2 wherein the detergent composition comprises at least about 12% by weight of said non-ionic detergent. 4. A method for washing according to claim 1 wherein the detergent composition comprises from about 5 to 30% by weight of the nonionic detergent, wherein the nonionic detergent is a polyethoxylated aliphatic alcohol or a polyethoxylated alkyl phenol. 5. A method for washing according to claim 4 wherein the detergent composition comprises at least about 20% by weight of said nonionic detergent. 6. A method for washing according to claim 5 wherein the flowability of the particulate detergent is about 70% or greater. 7. A method for washing, according to claim 6 wherein the bulk density of the detergent composition is at least about 0.6. 8. A method for washing according to claim 1 wherein the neck is threaded and the cap is a screw cap of such size as to measure about the desired charge, about 1/2 the charge, about 1/3 the charge, or about 1/4 the charge, when full, of particulate detergent composition for use in washing laundry in a washing machine. 9. A method for washing according to claim 1, wherein the detergent composition comprises about 60 to about 98% of base beads of detergent builder having porous outer surfaces and skeletal internal structures and from about 2 to about 40% by weight of a synthetic organic detergent material which is liquid or tacky at a temperature below 40° C., the synthetic organic detergent being disposed internally with the beads so that the outer surfaces of the beads are substantially free of said detergent. 10. A method for washing according to claim 9 comprising 70 to 95% of base beads and 5% to 30% of synthetic organic detergent, the base beads comprising from about 45 to about 85% by weight of a phosphate builder salt, from about 5 to about 15% by weight of alkali metal silicate and from about 5 to about 15% by weight of water and the synthetic organic detergent being a nonionic polyethoxylated detergent. 11. A method for washing according to claim 1 wherein the effective amount is about one quarter cup per about 17 gallons of wash water. 12.
