  • Publication number: 20010027301
    Abstract: A controlled-dose dispenser is useful to provide drops of liquid substances such as drugs, vaccines, ophthalmic solutions or other fluid solutions. The dispenser includes a body preferably made from two sheets of plastic material that are thermoformed in face-to-face relationship. A portion of the body is generally flat with a reservoir, which preferably is generally rounded, in a central portion. The reservoir is adapted to contain a chosen liquid substance. An outlet port is in fluid communication with the reservoir. An outlet nozzle is secured to the outlet port. A cap portion seals off the end of the outlet nozzle until a breakable or frangible connection is broken to remove the cap portion. Once the cap portion is removed, the liquid substance within the reservoir can be dispensed through the nozzle and the cap portion preferably cannot be replaced so that the dispenser is especially suited to be a single-use device.
