A coin-operated machine for vending and dispensing generally flat semi-rigid packets of irregular contour such as those used to package individual size servings of powdered drinks, cocoa, coffee, fruit drinks, etc., dehydrated broths and soups, and the like. The dispenser is especially adapted for use in locations such as offices, employee lunchrooms, school lunchrooms, and the like. The machine is characterized by a reciprocable coin-actuated slide bar provided with a friction member for engaging the lowermost packet in an overlying vertical magazine holding a plurality of packets in stacked relation for gravity feed operation. Deposit of a coin prevents engagement of a locking pawl with the slide bar and permits extension of the slide bar by pulling on an external handle to engage a packet of commodity and discharge it from the machine. The slide bar is spring biased for automatic retraction. Each machine includes one or more dispensing stations. Each dispensing station is operated by one or more coins of the same denomination. A further locking pawl is provided to prevent discharge of more than one packet without deposit of additional coins.
