Abstract: A condiment dispenser which is activated by an electrical vibrator is described. The dispenser has a container with a storage space filled with condiment. The bottom wall of the container is riddled with a multiplicity of spreading apertures. At the idle state the vibrator is deactivated and the apertures are blocked by a banded frame. The blocking frame isolates the condiment and prevents atmospheric moisture accumulation. At the active state the activated vibrator vibrates the condiment while the banded frame is moved such that the apertures are uncovered and facilitate condiment spreading. A multiple condiments dispenser is also presented. The multiple condiments dispenser has several separate containers and a vibrator which can vibrate all the condiments. The user selects which particular condiment to dispense by pressing the button which uncovers the apertures of the selected container while activating the vibrator.

Abstract: A condiment dispenser with a dispensing mechanism that automatically loosens condiment coagulation in the condiment container. The user can accurately control the amount of condiment sprinkled on the food because the dispenser dispenses substantially constant amount of condiment for each manual activation. In order to isolate the stored condiment and prevent it from accumulating atmospheric moisture, only the dispensed amounts of condiment are exposed by applying a novel dispensing method of loading measured condiment portions inside the storage, transferring them, unloading and spreading them outside. The dispensing mechanism seldom clogs since it employs wide cavities for measurement, transferring, unloading and spreading. The condiment dispenser has a simple structure which is inexpensive to manufacture. It can be held and operated using just one hand and it dispenses the condiment directly downwards without needing to downturn the dispenser. The dispenser also has an electrically motorized version.
