The cartridge includes a storage chamber for the reception of one or more filler materials and a neck which contains a discharge passage for each filler material. A shock absorbing element extends about the neck and is connected at one end to the neck. A closure cap is connected to the shock absorbing element or cartridge by a hinge to selectively open and close the discharge passage(s). When in the closure position over the discharge passage(s), the closure cap is recessed within and spaced from the shock absorbing element to avoid being loosened by an impact force. |
