Abstract
Abstract A dispenser for applying an adhesive mixture, the constituents of which are contained within the dispenser in the form of small capsules, including a hollow cylindrical housing having a piston member slidably positioned therein and sealingly closing one end thereof. The other end of the housing includes a closure portion having a plurality of bores formed therein, the bores having a diameter of a size smaller than the capsules. Means for moving the piston member are provided which enable the piston member to crush the capsules, mix the adhesive constituent and force the mixture through the bores provided in the closure portion.
