Abstract (en)

[origin: WO9937256A1] A cap includes an intermediate cap (60) and a cover cap (62) permanently secured together forming a cap chamber (10) and enclose the top of a housing (4) bone cement mixing chamber (5). A ribbed (84) contoured camming surface (86) is in the cap chamber (10) against which a received glass vial (9) is forced during insertion, breaking the vial head (11) and emptying the vial contents into the cap chamber (10) and then into the mixing chamber (5) through a fragment filter (92). The filter (92) and the ribbed (84) camming surface (86) traps glass fragments and vial head (11) in the cap chamber (10). The mixing chamber (5) is selectively coupled to an axially displaceable discharge tubular sleeve conduit (38) containing a feed auger (46). The discharge conduit (38) is axially opened to the mixing chamber (5) after completion of the cement liquid-powder mixing by rotating a collar (48) having a helix groove (54) connected to the sleeve (40). Various vial breaking cap embodiments are disclosed.
