  • a generic dispenser is known from GB-A-2 161 737.
  • the housing serves only as Container for storing the blades, from which the blades can be used if necessary pushed out by hand and then, for example, in a separate holder be used to perform special work with the blade can, especially cutting work.
  • the invention has for its object the housing of a blade dispenser in such a way that it can be used as a container for Store and remove unused blades as well as additional is also suitable for other uses, for example as a holder can serve for a blade partially ejected from it, so that the Dispenser also as a holder for a kind of knife in the manner of GB-A-2 161 737 can be used.
  • the invention provides a blade dispenser that is not only for Storage and dispensing of unused blades is suitable, but also used as a holder for a blade only partially ejected from it can be, so that it is a combination of blade dispenser and knife or Auxiliary knife forms.
  • the dispenser or its housing is designed so that it has a complete protection of the user when removing individual blades and also guaranteed when working with a partially extended blade.
  • a blade When a blade is pushed out normally, all edges are each blade to be pushed out including the ground edge of parts of the case until the user partially ejected it Pull the blade out completely and then, for example, into a separate holder starts.
  • the donor is used as a holder for a partially extended If the blade is used, the top blade of the stack of blades will go so far pushed out that a short piece of their cutting edge for the desired Cutting work is exposed or protrudes beyond the housing.
  • the rear end of the dispenser housing is preferably rounded, so the case is the handle of a knife like a kitchen knife is adapted and lies well in the hand of the user.
  • the cover of the housing is preferably the same with the body formed in one piece and injection molded in plastic, the connection is formed by a film hinge between the body and the lid. After this Insert a compression spring and a blade package into the open one The cover is folded onto the body and attached to it free edge provided barbs, which in corresponding openings of the Can lock the body, locked. Therefore, they are not separate Components required.
  • This closure is permanent and does not open by itself, but is secured against unintentional opening.
  • the Housing can therefore, after all blades have been removed from it, be disposed of inexpensively, especially if the spring arranged in it made of the same or the same material as the housing itself.
  • the slide In this latter position, the slide must be exerted on it Pressure should be kept as otherwise the one in a working position the blade is pushed out into the dispenser housing by slight pressure is pushed back. This forms an effective protection for the user against injuries. Because the blade extended into the working position slides back into the dispenser housing under cutting load if the User does not pressurize and hold the slider, the blade slides also back into the housing if the dispenser falls down, for example and the extended tip of the top blade on a more or less solid object hits.
  • the for a side edge protection of the extended blades provided standing webs or boundaries of the housing preferably at least partially sloping or sloping to the outside formed around the ends of the blades advanced between these webs to be able to grasp it better, for example by pointing to the ejected one Presses the end of the blade with your finger or thumb and the blade gripped in this way then pulls out of the case.
  • bayonet rivets be provided in corresponding holes in the dispenser housing can be used and snapped into place.
  • the blade dispenser shown in the drawing has one in the form of a Handle formed housing 1, which consists of a box-shaped Body 2 and a cover 3 closing this body. Of the Cover 3 is on a longitudinal edge via a film hinge 4 with the body 2 connected so that body 2 and cover 3 are injection molded in one piece in plastic can be.
  • the lid 3 is held in the closed position by barbs 5, which in slot-shaped recesses 6 in the relevant side wall 7 of the body 2 of the housing 1 snap, so that this closure is not without Can be released from the action of a tool.
  • each molded onto the lid 3 Barb 5 a conical body 35 with an upstanding molded thereon Has nose 34.
  • the barbs 5 can with play in the corresponding Recess 6 are inserted such that the conical body 35 a yielding deflection of the barb 5 allows and the nose 34 itself then sunk from the outside against one inside the recess 6 located paragraph 36 so that the barb 5 practically not protrudes beyond the outside of the side wall 7 of the body 2 of the housing 1.
  • the lid 3 contains one extending in the longitudinal direction thereof Elongated hole 16, which acts as a guide and limit position for a slide 17th serves, the details of which can best be seen from FIGS. 6 and 7.
  • the mutually inclined two inner ribs 14 are on both sides of the Elongated hole 16 arranged.
  • the slide 17 has two sections which are connected to one another in one piece on, namely a pressure piece located on the outside of the cover 3 18 and one on the inside of the cover 3 in the dovetail guide 15 guided driver 19, both wider than the slot 16 are and over a web-shaped neck 20, which is the width of the slot 16 is adapted are integrally connected.
  • the slide 17 can be moved into the elongated hole 16 by suitable tilting movements and insert the dovetail guide 15 so that it is captive is connected to the cover 3 and remains.
  • the slide 17 is injection molded in one piece from plastic, the one has certain elasticity, it is possible to face the pressure piece 18 the driver 19 around the neck 20, which in this case forms a type of joint limited to pivot.
  • the driver 19 has on its underside a paragraph 21 which as Stop serves and against the rear edge of the top blade 12 of the blade package 11 can be pressed to remove this blade from the Housing 1 through a slot 22 located at the front end thereof push out.
  • the pressure piece 18 has near its front end on the Bottom of a web 23, which acts as a limit stop against the can place the front end 24 of the elongated hole 16 to limit the distance around which the topmost blade 12 of the package 11 passes through the slot 22 be pushed out onto a support 25 adjoining the slot 22 can.
  • This support 25 is designed so that the end lying on it a partially extended blade 12 between the thumb and a finger of a user and completely out of the housing 1 can be pulled out.
  • the front edge 26 of the pad 25 is there corresponding to the front edge 27 of the housing 1, for example housed trapezoidal blades 12 beveled so that this front Edge 27 with blade 12 pushed out normally does not over the front edge 26 of the support 25 protrudes to avoid injuries to the user.
  • lateral webs 30 are provided also wedge-shaped in the direction of the front edge 26 of the support 25 taper to partially grip the front end extended blade 12 between the thumb and finger of a user facilitate.
