  The present invention, while retaining the excellent functions and effects of the conventional can lid excision tool, in combination with the excellent functions and effects, a novel and devised to be more convenient and more convenient It aims at providing a can lid excision tool.

  In order to achieve the above object, a can lid cutting tool according to claim 1 of the present invention includes a rotary cutting blade body and a rotary groove-type receiving blade body that are rotated by an operation handle and are moved closer to each other by an adjustment handle. The can lid excision tool is configured to cut off the rising edge wall portion existing on the inner peripheral surface of the gouge fastening edge portion that forms the periphery of the lid portion by simultaneous rotation of the body and the rotary groove type receiving blade body, A posture maintaining auxiliary guide ring is provided on the lower surface of the rotary groove-type receiving blade body so as to move in a state of being in contact with the outer peripheral surface of the can near the edge of the gouge.

  In addition, the can lid excision tool according to claim 2 is provided such that one vertical axis and the other vertical axis are freely rotatable on the support, and a fixed side gear is provided on the upper side of the vertical axis, and a rotary cutting blade is provided on the lower side. The movable side gear that meshes with and disengages from the fixed side gear is fixed to the upper part of the other vertical axis, and the rotary groove type blade body is fixed to the lower part, respectively, so that it cannot rotate. Alternatively, the operating handle is fixed to the upper end of the other vertical axis in a non-rotatable manner, and the other vertical axis can be moved in the perspective direction with respect to the vertical axis by making the shaft hole a long hole or supporting it via a slider. In addition, an adjustment device such as a screw rod with an adjustment handle for moving the other vertical axis to the near position and moving it to the near position or the far position and holding it at the far position is provided on the support body and the rotating groove. On the lower surface of the mold receiving blade body, the edge of the can is tightened In which is adapted to move the position maintaining auxiliary guide wheels provided in contact with the outer peripheral surface of the near point.

  Further, in the can lid excision tool according to claim 3, the force maintaining assist guide ring is fitted with an inner ring made of a synthetic rubber such as urethane rubber or an elastic material such as natural rubber in an outer ring made of a hard material such as metal or hard plastic. Thus, the outer ring 23 can be decentered by the elasticity of the inner ring 24.

  The can lid excision tool according to claim 1 or 2 includes the rotary cutting blade body and the rotary groove-type receiving blade body, which are rotated by the operation handle and moved away by the adjustment handle, as described above. FIG. 8 shows that the rising edge wall portion existing on the inner peripheral surface of the gouge fastening edge portion forming the peripheral edge of the lid portion is cut off by the simultaneous rotation of the rotary groove type receiving blade body. As can be seen, the cut 31 remaining in the empty can with the lid removed is cut into a highly safe diagonally separated state without the so-called burrs that cause the above-mentioned danger and a gouge fastening edge. The portion is overturned by the external pressure by the rotary groove type receiving blade body and the rotary cutting edge body and is covered with the cut, that is, the cut enters the back and the finger or lip is not easily touched, The superior machine that the conventional can lid resection tool has・ Achieving the same effect, and supporting the posture by being moved to the lower surface of the rotating groove type receiving blade body in contact with the outer peripheral surface of the can near the edge of the gouge Since the guide wheel for the maintenance is provided, the guide wheel for supporting the posture maintenance does not wobble the empty can during the cutting operation (it does not swing up and down) and guides it in a stable posture. It fulfills the function of preventing it. Therefore, it is possible to provide a novel can lid excision tool which is more in condition and more convenient in combination with the excellent functions and effects of the conventional can lid excision tool.

  In the can lid excision tool according to claim 3, the guide wheel for maintaining the posture is fitted with an inner ring made of a synthetic rubber such as urethane rubber or an elastic material such as natural gourd in an outer ring made of a hard material such as metal or hard plastic. Since the outer ring 23 can be decentered by the elasticity of the inner ring 24, the movement of the posture maintaining auxiliary guide wheel is smoothed by the decentering of the outer ring due to the elasticity of the inner ring, and the condition is further improved. A new can lid excision tool that is good and easy to use can be provided.

  1 and 2 show an embodiment of a can lid excision tool according to the present invention, in which FIG. 1 is a partial partially cutaway plan view, and FIG. 2 is a partially cutaway side view. is there.

  The can lid excision tool according to the present embodiment has a rectangular bar-shaped support body 1 provided with a front longitudinal axis 2 and a rear longitudinal axis 3 that are rotatable, and protrude above the support body 1 on the front longitudinal axis 2. The fixed-side gear 4 and the operation handle 5 are fixed to be non-rotatable at the position where the rotary cutting blade body 6 is fixed to be non-rotatable at a position protruding below the support 1 on the front vertical axis 2. The movable gear 7 is fixed in a non-rotatable manner at a position protruding above the support 1 on the rear vertical axis 3 and a rotating groove type receiver is positioned at a position protruding below the support 1 on the rear vertical axis 3. The blade body 8 is fixed so as not to rotate.

  The rear vertical axis 3 is configured to be movable back and forth by making the shaft hole 9 into a long and long hole. Further, a recess 10 is drilled in the front edge wall of the long hole shaft hole 9, and a spring 11 that constantly presses the rear longitudinal axis 3 rearward is incorporated in the recess 10. Further, a screw hole 12 penetrating the rear end wall surface of the support 1 is formed in the rear edge wall of the elongated hole-shaped shaft hole 9, and a screw rod 14 is screwed into the screw hole 12. The adjustment handle 13 is fixed to the outer end of the screw rod 14 so as not to rotate.

  Furthermore, the lower end of the rear vertical axis 3 protrudes from the lower surface of the rotary groove-type receiving blade body 8, and this protrusion comes into contact with the outer peripheral surface of the can 16 close to the gouge fastening edge 18. A posture maintaining auxiliary guide wheel 19 that moves in a state is provided.

  In addition, a hook portion 22 is provided at a front end portion of the support body 1 so as to be hooked in a hole of a pull top 21 that is preliminarily mounted on the lid portion 17 of the can 16.

  The guide wheel 19 for maintaining the posture is configured by fitting and integrating a urethane rubber inner ring 24 in a metal outer ring 23 and is attached to the rear vertical axis 3. In this state, the outer ring 23 can be freely decentered in accordance with the movement of the can 16 by the elasticity of the inner ring 24 made of urethane rubber. Reference numeral 25 in the figure denotes a spring presser for mounting the posture maintaining auxiliary guide wheel 19 so that it cannot be removed.

  In the can lid cutting tool according to the present invention, the fixed side gear 4 and the movable side gear 7 have different numbers of teeth, or the rotary cutting blade body 6 and the rotary groove type blade receiving body 8 have different radii. Or the amount of rotation by the operation of the operation handle 5 between the rotary cutting blade body 6 and the rotary groove-type receiving blade body 8 is different by, for example, different configurations of both the number and size of the blades. It is possible to do so. In such a case, the rotary cutting blade body 6 slightly slips on the rising edge wall portion 26 existing on the inner surface of the gouge fastening edge portion 18 in the can 16 (that is, moves so as to push out the same portion 26). , Dragging the kitchen knife and moving the sashimi sharply)

  The can lid excision tool according to the above embodiment can be used as follows, for example.

  First, the adjustment handle 13 is loosened, and the rear longitudinal axis 3, the movable gear 7 and the rotary groove type receiving blade body 8 are moved backward by the acting force of the spring 11. In this retracted state, the hook portion 22 is hooked into the hole of the pull top 21 and the edge of the lid portion 17 of the can 16 is clamped between the cutting edge of the rotary cutting blade body 6 and the receiving groove groove of the rotary groove type receiving blade body 8. 18 is positioned (see FIGS. 4 and 5).

  While maintaining this position, the adjustment handle 13 is turned and tightened to advance the rear vertical axis 3, the movable gear and the rotary groove-type receiving blade body 8, so that the gouge fastening edge 18 is received by the receiving blade of the receiving blade body 8. A state of entry into the groove, a state of pressure contact in which the cutting edge of the rotary cutting blade body 6 is in pressure contact with the inner surface of the outer peripheral vertical edge wall portion 26 of the lid portion 17 of the can 16, A contact state in which the outer peripheral surface is in contact with the outer peripheral surface of the can 16 near the gouge fastening edge 18 and a meshed state in which the movable gear 7 is meshed with the fixed gear 4 are set (see FIG. 6).

  In these contact state, pressure contact state, contact state, and meshing state (see FIG. 6), the gouge fastening edge portion 18 and the rising edge wall portion 26 are sandwiched between the rotary cutting blade body 6 and the rotary groove-type receiving blade body 8. The can 16 can be released by attaching, hooking the hook portion 22 to the pull top 21, and contacting the posture maintaining auxiliary guide ring 19 with the outer peripheral surface of the portion close to the gouge fastening edge portion 18. In this released state, as shown in FIG. 5, it is desirable that the direction of the can 16 and the direction of the support 1 form a substantially right angle.

  Next, with the adjustment handle 13 held with the left hand and the operation handle 5 held with the right hand, the adjustment handle 13 is turned slightly further by twisting the left hand while maintaining the above desired state. Then, by this tightening operation, the cutting edge 6 forms a biting state portion 27 in which the cutting edge bites into the rising edge wall portion 26 only slightly (see FIG. 6).

  When the biting state portion 27 is formed, the user turns the operation handle 5 while taking care not to shake the can 16 while holding the adjustment handle 13 with the left hand. Then, the stationary gear 4 and the movable gear 7 are rotated in opposite directions by the rotation of the operation handle 5, and the rotary cutting blade body 6 and the rotary groove type receiving blade are rotated by the rotation of the gears 4 and 7. The body 8 also rotates in the opposite direction together.

  Due to the rotation of the rotary cutting blade body 6 and the rotary groove-type receiving blade body 8 in the opposite directions, the rising edge wall portion 26 and the gouge fastening edge portion 18 are interposed between the rotary cutting blade body 6 and the rotary groove-type blade receiving body 8. It will go along while being drawn. In this case, in actuality, the biting state portion 27 is continuously formed on the rising edge wall portion 19 while the can 16 in the hand-released state slowly rotates as it advances along the direction, and a shallow score line is formed. By the way, it can be easily understood by associating that the gouge fastening edge 18 plays the role of a train track, and the rotary groove type receiving blade body 8 travels as a train wheel on this track. Let's go.

  Then, when the shallow cutting line goes around, the turning operation to the operation handle 5 is stopped, and after this stop, the adjustment handle 13 is rotated once again (in some cases, two or more rotations are possible), and the biting is performed. The operation handle 5 is rotated in a deeper and deeper state, and a deeper biting line 29 is obtained. Then, it is gradually deepened step by step several times to obtain a deeper cut line-shaped portion.

  On the other hand, in the operation of obtaining the cut line-shaped portion repeatedly as described above, each time the adjustment handle 13 is tightened, the rotary cutting blade body 6 becomes close to the rotary groove-type receiving blade body 8 and has a cross-sectionally U-shape. A folded state portion 30 is formed.

  As described above, when the cut line-shaped portion becomes deeper and the folded state portion 30 having a cross-sectional shape becomes a small angle, the rising edge wall portion 26 is finally cut off, and the lid portion 17 is It will fall into the can 16. In addition, since the pull top 21 is hooked on the hook portion 22 as described above, the dropped lid portion 17 can be easily and safely removed, and a hand is cut at the edge of the lid portion 17. Accidents such as

  The work of obtaining the cut line portion is stopped when it is confirmed visually that this has fallen. After this stop, the adjustment handle 13 is loosened to remove the whole from the can 16, and the lid part that has been cut off is removed from the can 16 by using the hook portion 22 to complete the operation. It should be noted that if the operation for obtaining the cut line portion is continued after the above confirmation, the entire gouge fastening edge portion 18 will be cut off. In order to prevent this from happening, it is possible to regulate the stroke of the rear vertical axis 3.

  By the way, when the state when the lid of the aluminum can is cut out using the can lid cutting tool according to the above embodiment is shown in enlarged cross-sectional order in the order of steps, it is as shown in FIGS.

  That is, FIG. 6 shows that the gouge fastening edge 18 enters the receiving groove of the receiving blade body 8 and the cutting edge of the rotary cutting blade body 6 is the inner surface of the outer peripheral vertical edge wall portion 26 of the lid portion 17 of the can 16. A state where the outer peripheral surface of the guide wheel 19 for maintaining the posture is in contact with the outer peripheral surface of the can 16 close to the seal fastening edge 18 and the movable side gear 7 is engaged with the fixed side gear 4 Is shown. FIG. 7 shows a state where a cutting line is obtained by biting the cutting edge of the rotary cutting blade body 6 and rotating the operation handle 5. FIG. 8 shows the moment when the lid portion 17 is cut off by deepening the cut line stepwise.

It is a partially omitted plan view showing an embodiment. Similarly, it is a partially omitted plan view. It is a front view which shows the use condition of embodiment. Similarly, it is a partially omitted plan view. It is a partially omitted side view. It is an expanded sectional view of the important section showing the initial state of a cutting process. It is an expanded sectional view of the important section showing a middle state state similarly. It is an expanded sectional view of the important section showing the latter term state similarly.
