Definitions

  • U.S. Patent No. 2,661,533 discloses razors which in cooperation with a blade dispenser permit changing of the blades without requiring handling of the new blade.
  • the razor comprises (1) a handle portion and (2) a head portion in which a single edged blade is forcibly held between resiliently separable cap and seat means. The blade is replaced by separating the cap and seat by inserting a key from the blade dispenser and ejecting the old blade under the force of the new blade as it is pushed from the dispenser.
  • the disepnser comprises the key member, a storage compartment for a stack of new blades, means for forcing the topmost blade against the top of the compartment and into endwise contact with a reciprocating blade pusher, and an exit slot for the topmost blade which is aligned so that the blade as it is pushed from the dispenser will enter the space between the separated cap and seat of the razor and engage the end of the used blade.
  • One object of the present invention is to provide novel blade dispensers having used blade compartments therein which can be readily and economically manufactured and assembled.
  • Another object of the present invention is to provide dispensers as set forth above which are constructed so as to prevent used blades from escaping through the entrance slot of the used blade compartment.
  • a further object is to provide a novel used blade compartment for an injector dispenser which compartment may be readily molded from inexpensive plastic material and simply snapped on to the dispenser.

  • the number of blades 21 remaining in the dispenser can be determined through a small viewing orifice 19 (FIG. 7) which is provided in the upper portion of the far side wall 22.
  • the blades 21 are held against the far. side wall 22 by an angularly disposed portion 27 of front end wall 24 which engages the beveled corners (not shown) of the sharp edges of the blades 21.
  • a slot 25 is provided between the top of the front end wall 24 and the top wall 18 through which the topmost blade may be ejected.
  • the blade pusher 30 which is reciprocally movable in the opening 28 comprises a blade-engaging member 32, connecting members 34 and finger engaging members 36.
  • the blade-engaging member 32 is in the form of a rectangular plate and is positioned within the compartment 14.
  • the width of the blade engaging member 32 is somewhat larger than that of the opening 28 so as to lock it within the new blade compartment 14 and its thickness is such that it will only engage the topmost blade 21.
  • a key member 38 which is adapted to be inserted into the head of an injector razor (not shown) such as disclosed in US. Patent No. 2,661; 553.
  • the key member 38 has cams 40 to 42 thereon which serve to spread the cap and seat of the razor apart; thereby releasing the pressure on the used blade and providing an opening into which the new blade 21 may be inserted from slot 25.
  • the back end of the dispenser 10 is closed off by a molded plastic end plug 26.
  • the end plug 26 is held in place by frictional engagement with inwardly directed dimples 44 and 46 (FIGS. 1 and 3) in the bottom and near side walls 16 and 20.
