Abstract: PROBLEM TO BE SOLVED: To obtain a container-packed granular detergent which is formed by packing a high-bulk-density granular detergent in a container with a built-in meter for metering the detergent, can be shaken out in a stabilized amount and therefore can be metered accurately by adapting the meter so that it may have specified properties. SOLUTION: The meter is desirably made of a metal or a plastic containing an antistatic agent to make it antistatic. It is further desirable that the meter is made of a plastic containing an antistatic agent and has surface resistivity 1×10 Ωor below as measure according to the method described in ASTM D257. The antistatic agent desirably comprises a poly(oxyethylene) alkylamine compound and/or a glycerol fatty acid ester compound. The greater part of the meter is desirably made of a plastic (e.g. PE) having a glass transition temperature of 25 deg.C or below.
