ABSTRACT:
A dispenser or shaker is used to store and dispense powdery or granular substances, and a sealing device for the shaker forms a seal against the escape of the substance between the lid and the shaker body. The lid can be placed around the mouth of the shaker body, and they can be rotated relative to one another to "lock" the lid onto the shaker body. The lid contains a number of dispensing holes through which the powdery or granular substance contained within the container body may be dispensed. The sealing device is located within the sealing lid, and provides a seal between the lid and the container body to prevent the powdery or granular substance from being ejected from the space between the sealing lid and the container body. The sealing device includes an inner and an outer ring made of materials that allow effective mounting of the device within the lid and formation of an effective seal, yet that provide for easy removal of the sealing device for cleaning.
