[Effect] The central part of the gripping part has a thin film structure for holding and fixing the base part of the cutting part by the gripping part serving as a support body of the cutting part, and a simple hinge having the same shape on the left and right of the thin film structure part. Holding the base of the blade part in a structure to secure it, and having a thick and almost quadrilateral shape of the simple hinge structure, with its curved part having curvature, each of the surface parts of the left and right hinge structures. Since a thin groove having a V-shaped cross section is formed in the central portion of the gripping portion so as to be parallel to each other along the portion of the thin film structure in the central portion of the gripping portion, and the thin film structure is made foldable, the base of the blade portion The cutting edge portion provided in front of the cutting edge is normally exposed to the outside by closing the cutting edge portion from both sides of the cutting edge to protect the cutting edge portion by the opening / closing member located in front of the grip portion. There is an effect that can be prevented. In particular, there is an effect that the iron piece and the magnet are disposed inside the opening / closing member at positions that can correspond to each other, and the closed state can be reliably maintained. Further, on the inner side or the back side of the simple hinge structure of the grip portion located behind the pivotal support portion of the opening / closing member, one has a protrusion at the corresponding position and the other has a recess such as a hole into which the protrusion is fitted. By providing a portion, the base portion of the blade portion can be securely clamped and fixed, and at the portion such as the notch or through hole provided in the base portion of the blade portion, the protruding portion holds the engaged state so that It has the effect of preventing retention to the outside. Further, the pivotal support portion of the opening / closing member forms a V-shaped cross-sectional shape from the outside to form a thin film portion. By setting the angle of inclination of the V-shaped cross-section portion to approximately 45 degrees, With the opening / closing member opened to the maximum, the opening / closing members located on the left and right of the cutting edge of the blade can be opened up to about 90 degrees, and the corners of a paper container having a rectangular parallelepiped shape or a cube shape are shown in FIG. As shown, there is an effect that the opening / closing member can be moved in the direction of the corner line by using the opening / closing member as a guide member to surely and easily incise the corner portion. Further, in manufacturing the one shown in FIG. 1, the grasping portion and the opening / closing member of the incision instrument for dissecting a container according to the present invention are connected to each other in a thin film structure.
Although the bases of the blades are clamped and fixed at the opposing portions of the grips, it is efficient in terms of molding to integrally connect the opposing grips with a thin film portion. On the other hand, there is also a drawback that the cost of manufacturing the mold becomes high. Therefore, when selecting one of the manufacturing methods, it is only necessary to mold it once. Therefore, by combining the two basic structures as a unit body and by individually manufacturing and molding the unit body It is necessary to carefully consider which manufacturing method is preferable between doubling the labor and to select either manufacturing method. Further, as shown in FIG. 2, when the right thick member and the left thick member are stacked, the magnet is positioned corresponding to the iron piece, and one of the thick members is attached to a plurality of mounting positions to make the iron piece. Needless to say, by using the other magnet, there is no confusion in the selection of the polarities, and the iron piece is arranged to be attracted to the magnet at the corresponding position of the other thick member. In addition, the overall structure is extremely compact and has an extremely strong structure, which is suitable for the user to carry around at all times. In addition, since the cutting blade part of the knife is securely closed by the opening / closing member when carrying, not only is there no risk of injury, and if necessary, put a nail or a thin piece on the nail hook opening. There is an effect that can be easily opened. In addition, the wall thickness of the blade can be selected arbitrarily from extremely thin to thick, and it can be fitted in a predetermined position.The edge of the protrusion provided inside the gripping portion can be placed at an appropriate position on the base of the blade. Locking the provided notch or through hole has the effect of completely preventing movement in the front-back and lateral directions. In addition, by relatively increasing the attractive force of the magnet,
Although opening the opening / closing member is difficult at first, pressing the corner of the empty pack allows the opening / closing member to be opened at a desired angle, which facilitates incision.
