Embodiment Construction

[0075] refer to Figure 1-5 , a metering and dispensing closure, generally indicated at 10, is shown in connection with a container 12 supported in a dispenser assembly or reservoir 14 serving as a housing for the closure 10. A water inlet conduit 16 controlled by a solenoid valve 18 is used to introduce water into the dispenser assembly or reservoir 14 . An aqueous solution outlet conduit 20 also communicates with the dispenser assembly or reservoir 14 . The drive member 22 powers a drive shaft 24 which is journaled in a bushing 26 with a seal 28 .

[0076] refer to figure 2 , one can see that the metered dispensing head, usually denoted by 10, consists of three basic parts. There is a lid member 30 having an upstanding wall 31 and internal threads 32 for engaging complementary threads on the container 12 . There is also a rotating disk 36 which has a raised peripheral wall 37 and a notched portion 38 . The rotating disk 36 is placed inside the cover member 30 . The th...

Abstract

A metering and dispensing closure for a container wherein two rotatable disks rotate in conjunction with a stationary cap member to afford accurate measuring of a powder material and dispensing of it. The disks and the container cap afford a consistent measuring of the powder material, as well as provide a variety of drive members which can be utilized with the dispensing closure.

Description

[0001] related application [0002] This application is a continuation-in-part of now pending US Patent Application Serial No. 10 / 709,449, filed May 6, 2004. Background technique [0003] The field of the invention is metering and dispensing devices for powder or granular materials. More specifically, it relates to powder dispensing caps that attach to containers and dispense precise amounts of powder into liquids or containers. [0004] Dispensers of the type concerned by this invention are disclosed in US Patent Nos. 4,032,050 and 5,469,992. These dispensers all disclose rotating metering discs (80 and 20 respectively) for dispensing the material. There are some problems with using a rotatable assay block and a stationary feed block. These do not produce the desired internal agitation of the container contents. Without this effect, a considerable amount of powder may remain in the container and not settle into the assay chamber. [0005] The prior art does not provide a...
