Description

A cutter with a snapped blade container,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stationary or cooperating cutter knife, and more particularly to a cutter knife provided with a blade collection box capable of receiving a cutter blade piece.

Cutter knife is known to have been made by Japan's Okada Yoshida in 1956. Yoshida, who was in the printing business, was in the process of solving the problem of easily cutting the paper cutting knife, I was inspired. At that time, some of the Japanese artisans were cutting paper using broken glass. Before the cutter knife, when the knife was dull, it was inconvenient because the whole knife had to be discarded, but by using the cutter knife, it was possible to cut off the cutter end and continue to use it.

Such a cutter knife has the advantage that it can maintain the sharpness of the knife edge, but there is a disadvantage that the risk of a safety accident is high in cutting the blade. In addition, careless handling of the cut pieces of the blade may cause infants or pets to swallow it or injure them, which is not easy to use.

[0001] The present invention relates to a housing, a housing, a slider for holding the blade at the front end of the housing, And a stopper fitted to the cutter knife; The stopper is formed with an insertion portion to be inserted into the housing as one side of the stopper body. A magnetic slider, which is drawn out from the stopper main body and accommodates a magnet, is installed at an upper portion of the insertion portion, Wherein the cutter blade is cut by inserting a blunt blade.

The comparison technique is a technique for preventing a blade piece from splashing by using a magnet when cutting a blade, and is designed to realize a desired purpose by a relatively simple structure. However, there is a risk that a blade cut off by the above-mentioned design is lost or is not properly treated, thereby causing a secondary safety accident. However, the above design does not provide a technique for preventing this.

SUMMARY OF THE INVENTION In order to solve the above-described problems, the present invention provides a cutter in which cut pieces of a blade are collected by a magnet into separate blade collectors when a blade is cut. The blade collection box may be separated from the back cover by a drawer method so that it can be safely treated when the blade pieces are uniformly gathered.

In addition, a blade indicator is provided to warn the user with a fluorescent label that can be used when the blade is not completely housed in the sleeve, thereby preventing unexpected accidents.

1 and 2, the present invention may include a sleeve 110, a housing 120, a back cap 140, a blade collection box 146, and the like.

In the present invention, the sleeve 110 is coupled with a separate housing and is disposed inside the housing 110. The sleeve 110 is provided to accommodate the blade in a general cutter knife structure, And is provided in a configuration in which the blade is housed and guided to guide the receipt and delivery of the blade.

The sleeve 110 is generally made of a steel material and a guide rail 112 may be provided to allow the blade transfer handle 113 to be inserted and to be movable back and forth. The sleeve 110 is provided with the guide rails 112 in a state that one side of the long side thereof is opened with a predetermined width, and the blade feed handle is inserted along the opening to start the operation. The guide rails 112 are generally formed in the form of an L-shaped so that the elastic force of the elastic members provided on the blade feed handle 113 makes it possible to keep the blades in and out according to the distance between the latches.

The housing 120 is provided so as to cover the entire outer surface of the sleeve 110 and has a length shorter than that of the sleeve 110 so that the slit portion 111 in which the blade 160 is inserted and removed from the sleeve 110 can be protruded . The housing 120 is provided to improve the grip feeling of the cutter body 100, thereby preventing a risk of accidental accident due to a missing cutter during operation. Therefore, the housing 120 is generally made of a synthetic resin material, and may be provided so as to be bent or slid-resistant in order to improve grip feeling on the outside.

The blade indicator 114 is provided on the inner bottom surface of the sleeve 110 so that the blade conveyance handle 113 is actuated to advance along the guide rail 112 and the blade 160 is discharged, The bottom surface of the sleeve 110 is exposed to warn that the blade 160 has been discharged. This is not an active warning method and can be provided by attaching a color label of a fluorescent material having high visibility or painting the inner surface of the sleeve 110 with a luminous paint so that the user can visually confirm this visually.

The luminescent material is generally called a phosphorescent phosphor that emits visible light by irradiating light of a shorter wavelength than ultraviolet light such as zinc sulfide. It is also referred to as a phosphorescent coating material that emits light for a long time in the dark when irradiated with sunlight or lamp light. By processing the blade indicator 114 as such a luminous paint, it is possible to easily confirm whether or not the blades are derived even in low-light conditions at night where the visibility is insufficient.

The back cap 140 may be provided on the other side of the sleeve 110 to prevent the blade feed handle 113 from being separated. A cutting slit 145 is provided on one side of the upper end of the back cap 140 to cut the blade 160. The cutting slit 145 extends through the inside of the back cap 140 to the receiving opening 143 provided inside the back cap 140. [ The receiving opening 143 is provided so as to accommodate the blade collecting box 146 so that the blade cut by the cutting slit 145 is seated on the blade collecting box 146.

Referring to FIG. 3, a magnetic material 144 may be embedded in one side wall of the receiving opening 143 so that the cut blade can be smoothly received by the blade collecting box 146. That is, the magnetic material 144 is embedded in the wall surface of the receiving port 143, which is in contact with the bottom surface of the blade collection box 146, so that the blade piece, which is cut at the cutting slit 145 and moves to the inside of the back cap 140, So that it is seated by the blade collection box 146. [

When the blade pieces are seated in the blade collection box 146, the magnetic material 144 attracts the blade pieces, thereby preventing the blade piece from flowing out to the outside through the cutting slit 145. When the blade collecting box 146 is full, the blade collecting box 146 can be taken out from the receiving port 143 by putting a nail on the groove 146a provided at one side of the blade collecting box 146. [ The blade pieces in the blade collection box 146 separated from the receiving opening 143 can be easily taken out and treated in the blade collection box 146 as the magnetic force of the magnetic body 131 is released.

Referring to FIG. 4, the blade collecting box 146 has both side edges of the upper portion bent in a stepped manner to prevent interference with a blade inserted into the cutting slit 145. That is, when the blade collection box 146 is accommodated in the back cap 140, the portion may be folded so that the cutting slit 145 is not blocked by the portion contacting the cutting slit 145. A slit of the same or slightly larger shape as the cutting slit 145 is provided on one side of the blade hopper 145 so that the slit is aligned with the cutting slit 145 when the blade hopper 145 is housed in the back cap 140 So that the blade pieces can be seated in the blade collecting box 145.

The operation of the cutter provided with the blade cart according to the present invention will now be described.

The user pushes the blade feed handle 113 to advance the blade 160 forward so that the blade 160 is discharged through the slit portion 111 as needed. At this time, the blade indicator 114 is exposed on the inner surface of the sleeve 110 opened to the rear of the blade conveying handle 113. Even if the user puts the cutter 100 down in this state and sees other tasks and discovers that the blade 160 of the cutter 100 is exposed from the sleeve 110, It is possible to draw attention to the blade which is easily exposed by the blade indicator 114. [

When the knife 160 is weakened by using the cutter 100, the knife 160 may be cut by separating the back cap 140. When the end of the blade 160 is inserted and cut in the cutting slit 145 provided at one side of the back cap 140, the blade cut by the magnetic body 144, which is embedded in one side wall of the receiving opening 143, So that the user can attach the back cap 140 to the rear end of the sleeve 110 and continue the operation.

When the blade collecting box 146 is full, a nail is put on the groove 146a provided at one side of the blade collecting box 146 to take out the blade collecting box 146 from the back cap 140 and treat the received blade piece. At this time, the blade collecting box 146 may be coupled to the receiving opening 143 in an interference fit manner.
