Abstract
An ampule having a body portion and a sealed end portion and a sealed delivery portion adapted for use in a delivery syringe system for controllably dispensing a low viscosity material, such as a liquid, gel, or paste. An ampule having sealed rear portions adapted to mate with a plunger of a syringe so as to facilitate controlled dispensing of a low viscosity material. The syringe has a breach positioned to provide controlled flow of the dispensed low viscosity material and facility easy removal from the syringe. Low viscosity materials, such as liquids and gels, are controllably dispensed in a measured unit dose quantity. The present invention has many applications, but is particularly applicable to dispensing low viscosity materials such as used in coatings and not injected parenterally, and is particularly applicable to dental applications.
