  • Patent number: 5490615
    Abstract: The dispenser has a plunger which is pressed downwardly by the user to dispense condiments, such as salt, pepper, sugar, spices, etc. An adjusting device can be set to determine a predetermined amount to be dispensed by each stroke of the plunger. The plunger structure has a dispensing head which passes through an outlet opening in the base of the device. The head has a plurality of vertically spaced recesses with walls separating the recesses. The walls form an acute angle with the plane of the outlet opening. The base can be slipped over a resilient sealing member at the lower end of the dispensing head to remove and replace the base for refilling and cleaning of the dispenser. Resilient seals are used to seal the openings between the housing and the outside air so as to minimize clogging and jamming of the moving parts of the device due to humid air. The plunger can be locked to prevent unwanted dispensing, and to tighten the seals to facilitate washing, refilling and transportation of the dispenser.
