Description

Magnetic knife case combined with cutter knife {MAGNETIC TYPE CUTTER BLADE CASE USABLE AS SNAP-OFF BLADE CUTTER}

The present invention relates to a blade case which allows a plurality of blades to be stored inside and withdraw one by one if necessary. More specifically, the blades can be simply withdrawn by a magnet without the addition of a complicated configuration. Rather, it relates to a magnetic knife case combined with a cutter knife that can be used in a state in which the tip of the blade is drawn out by magnetic force, so that it can be used similarly to a conventional cutter knife.

In general, since the blade is made of sharp metal, the blade is packaged and distributed in a case to prevent the blade from being damaged or injured by the blade. However, the conventional blade case is configured to open the cap as necessary to remove the blade, the draw operation is very inconvenient as well as a problem that can be injured by a sharp blade during the withdrawal of the blade.

As part of solving such a problem, Korean Patent Registration No. 10-0491076 (registered on May 13, 2005) stores a plurality of blades used for one-time use in a case, so that a plurality of blades can be drawn out and used one by one if necessary. In the blade case to be able to accommodate, the guide rail is opened in the lower portion is formed in the center and the barb tooth rail is provided on both sides, both sides are integrally formed on the front plate and the bottom of the front plate formed with the engaging projection A body formed of a bottom plate having an insertion hole communicating with the open end of the guide rail, and coupling grooves are formed at both inner side surfaces thereof so as to be inserted into the coupling protrusion of the main body, and spaces are formed in the upper surface of the blade to accommodate the blades. Withdrawal guide hole is provided in communication with the part and pushed out through the withdrawal guide hole on the upper end of one side A cover formed with a drawing hole for drawing out the blade is slide-coupled, an elastic ball is formed in the upper portion of the body to support the blade is stored in the space portion of the cover and formed in the guide groove spaced a predetermined distance on the front of the body Is provided with a handle, the elastic handle is provided with a push rod formed in the bottom plate of the main body is provided with a barb is formed in the bottom plate of the main body is inserted into the barb tooth rail of the main body on both left and right sides, one end of the cover is inserted into the lower blade A waste blade insertion hole which can be formed may be formed, and an upper portion of the cover may include a withdrawal member which forms an outlet opening extending to one side end and is provided in the outlet so that the hinge member is coupled to allow hinge rotation. The case is posted.

In addition, Korean Patent Publication No. 10-2012-0034463 (published on Dec. 12, 2012) discloses a blade case in which blades are individually drawn out one by one in a state in which a plurality of blades are stacked so that the case is placed in an internal space.
