  By the way, in the storage devices having the configurations described in Patent Documents 1 and 2, the first and second storage chambers are closed with a lid. In such a storage tool, a blade groove is provided at a position above the second storage chamber of the lid body in order to fold the blade edge and to discard the used cutting edge as waste in the second storage chamber. In many cases, a mode in which the second storage chamber is communicated to the outside through the blade groove is employed. Thus, in such a storage tool, a person who normally uses such a replacement blade storage tool knows that the stored item in the replacement blade storage tool is a waste of the replacement blade and the used replacement blade. So handle with great care. That is, rough handling such as applying strong vibration cannot be performed. However, children and the like do not know that the stored items of the replaceable blade storage device are wastes of the replaceable blade and the used replaceable blade, or do not know that the replaceable blade storage device should be handled with great care. When a person applies a strong vibration to the replaceable blade storage tool, a problem may occur in which the cutting edge, which is the waste stored in the second storage chamber, spills out from the blade groove.

  The present invention is configured to solve the problems described above.

  That is, the replaceable blade storage tool according to the present invention can store the replaceable blade of the cutter knife in the first storage chamber formed by opening substantially the entire upper end and the blade edge of the used cutter knife inside. A storage tool body that includes a second storage chamber that is openable on the upper surface and capable of storing the blade edge of the cutter knife and that can be stored in the upper surface; A window portion provided at a position where the storage chamber is closed and overlapped with the blade groove of the second storage chamber, a closed position which closes at least a part of the window portion and the blade groove, and at least the blade groove A window closing body that is movable between an open position that allows the entire region to communicate with the outside, and a lid body that has a closing body locking portion that locks the window closing body at the closing position. To do.

  If this is the case, the window closing body is placed in the closed position when not in use, and the window closing body is locked in the closed position by the closing body locking portion, so that the storage tool can be mistaken. Even when a strong vibration is applied, the window closing body is locked in the closed position, so that the whole of the blade groove is exposed to the outside space, and waste spills out through the blade groove. It is possible to suppress the occurrence of malfunctions.

  As an example of the mode of the window closing body of such a replaceable blade storage device, the lid body is rotatable with the lid body having the window portion and one side edge portion as an axis center with respect to the lid body. And a window closing body connected to the. In such a case, the entire lid body can be handled integrally, and if the window closing body is arranged at a position other than the closing position, the free end of the window closing body is separated from the lid body, so that the window closing body is closed. You can check forgetting at a glance.

  In particular, as a configuration capable of more prominently obtaining the effect of being able to handle the entire lid described in the previous section as one body, a structure in which the lid body and the window closing body are integrally molded can be cited. .

  Further, if the closing body locking portion is formed by engaging the opening edge of the window portion with a locking claw provided at the free end of the window closing body, the window closing body is locked. Such a closure locking part can be realized without using a special member.

  In particular, if the window closing body can be elastically deformed, the locking claw can be projected and retracted by elastically deforming the window closing body, and the above-described effects can be obtained more suitably. it can.

  Furthermore, as an aspect for facilitating opening and closing of such a window closing body, the upper edge of the first storage chamber closing portion that closes the first storage chamber of the lid body is horizontal. In the closed position, the window closing body has an inclination that descends toward the hinge portion. If it is such, after a finger etc. are slid horizontally along the upper edge of said 1st storage chamber obstruction | occlusion part, a finger etc. are hung near the free end of said window obstruction | occlusion part, and it slides horizontally as it is. This is because a part of the force applied to the vicinity of the free end of the window closing part is distributed as a circumferential action when the window closing part is rotated about the hinge. In the present invention, “horizontal” is a concept indicating that the first storage chamber is horizontal when arranged so as to open vertically upward.

  In particular, when the window closing body is disposed at the closed position, the free end of the window closing body or a portion in the vicinity thereof is located above the upper surface of the first storage chamber closing portion. Since the finger hits the free end of the window closing body after sliding horizontally along the upper edge of the first storage chamber closing portion, the opening / closing operation can be performed more easily.

  If the first storage chamber closing part is provided with a recess, and the window closing body is disposed at the closed position, the window closing body may be closed if the free end of the window closing body faces the recess. Without causing the free end of the body to protrude upward, the finger can be applied to the free end of the closed window body after the finger or the like is slid horizontally along the upper edge of the closed portion of the first storage chamber.

  The replaceable blade storage device according to the present invention closes the first storage chamber in a state where the replacement blade storage device is mounted on the storage device main body, and a window portion provided at a position overlapping with the blade folding groove of the second storage chamber, A window closing body movable between a closing position for closing at least a part of the window portion and the blade groove and an open position for exposing at least a substantially entire region of the blade groove to the outside, and closing the window closing body And a lid body having a closure body locking portion that locks in position, so that the window closure body is placed in the closed position when not in use, and the window closure body is engaged in the closed position by the closure body locking portion. It can be stopped. Therefore, even when a strong vibration is accidentally applied to the storage device, the window closing body is locked in the closed position, so that the entire blade groove is exposed to the external space, and the blade groove is inserted through the blade groove. Therefore, it is possible to suppress the occurrence of defects that cause waste to spill out.

In addition, the first storage chamber closing portion 212 is provided with a concave portion 212x that is inclined downward toward the center in the width direction. In addition, the upper edge of the portion of the support frame 211 that is located on the side of the second storage chamber 1t in the mounted state corresponds to the upper edge of the second storage chamber 1t and descends toward the side edge. The shape has an inclination. 4A shows a state in which the window closing body 22 is arranged at the closing position S, and FIG. 4B shows a state in which the window closing body 22 is arranged at the opening position O.

  In the present embodiment, the window closing body 22 is provided integrally with the lid body 21 and is disposed above the second storage chamber 1t at the closed position S. Specifically, the hinge portion 223 is set at one end portion of the window closing body 22, and the hinge portion 223 is connected to the upper end of one side surface of the support frame portion 211 of the lid body 21. . The entire lid 2 is integrally formed of resin so as to be elastically deformable. Further, a locking claw 221 is provided at the free end of the window closing body 22, and the locking claw 221 is engaged with the window portion 21 x of the lid body 21 at the closed position S. That is, the closing body locking portion 23 is formed by engaging the locking claws 221 and the window portion 21 x of the lid body 21. Further, an operation projection 222 that faces the recess is provided above the locking claw 221.

  Below, the aspect of use of this replaceable blade storage tool C is described.

  When taking out the replaceable blade E from the replaceable blade storage tool C, the lid body 21 is elastically deformed to disengage the holding protrusion 17 from the holding recess 211x, and then the cover 2 is stored. The tool body 1 is moved upward. By operating in this way, the attachment of the lid 2 to the storage device main body 1 is released. Then, in this state where the cover 2 is released, that is, with the cover 2 removed, the replaceable blade storage tool C is shaken up and down, or the replacement is performed so that the opening of the first storage chamber 1s faces downward. By tilting the blade storage tool C, the replacement blade E jumps out of the first storage chamber 1 s, picks up the protruding replacement blade E, and takes it out of the replacement blade storage tool C.

  On the other hand, when the cutting edge EE is folded and used, and the cutting edge EE is stored in the spare blade storage tool C, the following operation is performed. First, the operation projection 222 of the window closing body 22 is pressed horizontally outward. Then, the window closing body 22 is elastically deformed, and the engagement between the locking claw 221 and the opening edge portion of the window portion 21x of the lid body 21 is released. When the operation projection 222 is further pressed horizontally outward, a part of the pressing force is in the circumferential direction when the window closing body 22 is used as the center of the connection portion 23, that is, the window closing body 22 is used as the lid body 21. In addition, the second storage chamber 1t acts to move away from the upper edge. By operating in this way, the window closing body 22 moves to the open position O while the lid 2 is attached to the storage body main body 1. Then, the blade edge of the cutter knife is inserted into the blade fold groove 16s, and the used blade edge EE is separated and stored in the second storage chamber 1t as it is by bending the blade vertically into the blade fold groove 16s in the direction of the face plate of the blade. . After completion of this operation, the window closing body 22 is moved to a position where the free end faces the window portion 21x of the lid body 21. Then, when the window closing body 22 is further moved, the window closing body 22 is elastically deformed, and the locking claw 221 is temporarily retracted from the opening edge of the window portion 21x, and when further moved, the shape of the window closing body 22 is changed. The locking claw 221 is restored and engaged with the opening edge of the window portion 21x. In this way, the window closing body 22 is arranged at the closing position S, and the second storage chamber 1t is closed.

  As described above, the replaceable blade storage tool C according to the present embodiment arranges the window closing body 22 at the closing position S and closes the second storage chamber 1t. Even if it is accidentally swung strongly, as long as the closing body locking portion 23 is functioning, that is, the engagement between the locking claw 222 of the window closing body 22 and the opening edge of the window portion 21x of the lid body 21. Unless the combination is released, the first storage chamber 1s is closed by the first storage chamber closing portion 212 of the lid body 21, and the second storage chamber 1t is closed by the window closing body 22, so that the unused blade E And the used cutting edge EE does not jump out of the storage tool. Furthermore, since the window closing body 22 can be positioned at the open position O while the lid 2 is mounted on the storage device main body 1, the substantially entire region of the blade folding groove 16s can be communicated with the outside, so that the blade folding groove 16s can be communicated. A high frequency operation of folding the movable blade edge EE and storing the used blade edge EE in the replaceable blade storage tool C can be easily performed by opening and closing the window closing body 22. That is, the attachment / detachment of the lid body 2 may be performed only during an infrequent operation of taking out a new spare blade E from the replacement blade storage tool C, and the labor of attaching / detaching the lid body 2 to / from the storage device body 1 can be reduced. .

  The lid body 2 includes a lid body 21 having the window portion 21x, and a window closure body 22 connected to the lid body 21 so as to be rotatable about a hinge portion 223 set at one side edge. Therefore, when the window closing body 22 is arranged at a position other than the closing position S, the free end of the window closing body 22 is separated from the lid body 21. Forgetting to close the closure 22 can be confirmed at a glance.

  In particular, since the lid body 21 and the window closing body 22 are integrally formed, the effect that the entire lid body 2 described in the previous stage can be handled integrally can be obtained more remarkably.

  The closing body locking portion 23 engages an opening edge of the window portion 21x and a locking claw 221 provided at a free end of the window closing body 22, and the closing body locking portion 22 Since it can be elastically deformed, such a closing body locking portion 23 can be realized without using a special member for locking the window closing body 22.

  The upper edge of the first storage chamber closing portion 212 that closes the first storage chamber 1s of the lid 2 is horizontal, and the window closing body 22 descends toward the hinge portion 223 at the closed position S. Since it has an inclination, after a finger or the like is slid horizontally along the upper edge of the first storage chamber closing portion 212, the finger or the like is placed on the operation projection 222 in the vicinity of the free end of the window closing portion 22. As a result, a part of the force applied near the free end of the window closing part 22 acts as a circumferential action when the window closing part 22 is rotated about the hinge part 223 as an axis. Distributed. Therefore, it is possible to easily open and close such a window closing body 22.

  When the window closing body 22 is arranged at the closing position S, the operation projection 222 set at the free end of the window closing body 22 or a portion in the vicinity thereof is located above the upper surface of the first storage chamber closing section 212. Therefore, the finger hits the free end of the rear window closing body 22 when the finger or the like is slid horizontally along the upper edge of the first storage chamber closing portion 212, and the opening / closing operation can be performed more easily.

  Since the first storage chamber closing portion 212 is provided with a recess 212x, and when the window closing body 22 is disposed at the closing position S, the free end of the window closing body 22 faces the recess 212x. The finger or the like is horizontally slid along the upper edge of the first storage chamber closing portion 212 without causing the operation projection 222 of the window closing body 22 to protrude above the upper surface of the other portion of the window closing body 22. The finger can be applied to the free end of the window closing body 22 after being moved.

  The present invention is not limited to the embodiment described above.

  For example, an aspect in which the window closing body is slidably attached to the lid body is also conceivable. In this aspect, for example, a guide groove for guiding the moving direction of the window closing body may be provided on the lid body side, and a closing body locking portion may be provided between the guide groove and the window closing body. For example, the closure body locking portion has a configuration in which a convex portion provided in the guide groove and a locking recess portion provided in the window closure body are engaged in an uneven manner, or a convexity provided in the window closure body so as to be able to project and retract by elasticity. It is preferable to adopt a configuration in which a concave portion provided in the guide groove and a concave portion provided in the guide groove are engaged.

  Further, instead of providing a closing body locking portion configured to engage a locking claw provided at the free end of the window closing body at the opening edge of the window portion, the opening edge of the window portion is elastically formed by a locking protrusion or the like. A projecting part that can be projected and retracted, a locking concave part that can be engaged with the convex part is provided on the free end side of the window closed end, and the closure body structure is configured by engaging the convex part and the locking concave part. A stop may be provided.

  Furthermore, you may form the cover body of the state which has arrange | positioned the window closing body in the closed position in a rectangular parallelepiped shape.

  In addition, instead of causing the free end of the window closing body to protrude above the first storage chamber closing portion of the adjacent lid body in the closed position, the upper surface of the free end edge of the window closing body is adjacent in the closed position. A step is provided between the upper surface of the free end edge portion of the window closing body and the upper surface of the other part of the window closing body so as to be positioned below the upper surface of the first storage chamber closing portion of the lid body. Even if it does in this way, it can be made to perform opening and closing operation of a window closing body by putting a finger on this level difference part, and the effect which becomes easy to perform opening and closing operation is acquired. On the contrary, even if the first storage chamber closing portion of the lid body is not provided with a recess as in the embodiment described above, the free end edge portion of the window closing body is located above the upper surface of the first storage chamber closing portion. Even in a mode in which the protrusions provided in a protruding manner are provided, the window closing body can be opened and closed by placing a finger on the protrusions, and an effect of facilitating the opening and closing operation can be obtained.

  In addition, various modifications can be made without departing from the spirit of the present invention.
