An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an unpacking tool provided with a cutter according to one embodiment of the present invention in a stored posture. FIG. 2 is a perspective view of the unpacking tool with the cutter open. As shown in FIG. 1 , the unpacking tool includes a case composed of a first case 41 and a second case 42 and a cutter 3 . In addition, an applicator having a roller (not shown) is further provided at the bottom of the unpacking tool. The application part is for hiding personal information printed or written on the packing box.

First, the case of the unpacking tool will be described. As shown in FIGS. 1 and 2, the entire case has a substantially egg shape and is composed of a first case 41 and a second case 42 . A side portion of the first case 41 is formed with a recessed portion 415 to be gripped by the user. Further, although not shown, the second case 42 also has a depression corresponding to the depression 415 of the first case 41 to be gripped by the user. Each recess is formed so as to be recessed inside from the surface.

As shown in FIG. 2, a concave portion 414 is formed from the top portion to the side portion of the mating surface of the first case 41 with the second case 42 . A recess 424 is formed in the portion of the second case 42 corresponding to the recess 414 . A groove 43 is formed between the recess 414 and the recess 424 in the mating surfaces of the first case 41 and the second case 42 . The recess 414, the recess 424, and the groove 43 are for storing the cutter 3 in the storage posture. Further, on both sides of the groove 43 , recesses 414 and 424 and recesses 411 are formed in the first case 41 and recesses 421 are formed in the second case 42 at positions above the lower end of the groove 43 . there is The recessed portion 411 and the recessed portion 421 are symmetrical with each other and form a substantially elliptical recess.

Next, the cutter 3 will be described with reference to FIG. As shown in FIG. 3, the cutter 3 is mainly composed of a cutter main body 31 and a restricting portion 32. As shown in FIG. The cutter main body 31 and the restricting portion 32 are integrally formed of resin by injection molding. As the resin, a resin having a certain hardness, such as ABS, can be used. Since the cutter 3 is made of resin, it is safer than when the cutter 3 is made of metal. The cutter main body 31 is formed in a plate-like shape, and a long restricting portion 32 is formed on the side where the blade portion is not formed (more specifically, the back portion on the side opposite to the second blade portion 333 described later). there is The restricting portion 32 extends perpendicularly to the cutter main body 31, and the restricting portion 32 and the cutter main body 31 are T-shaped when viewed from the end.

As shown in FIG. 3, the restricting portion 32 is formed in a shape protruding in the longitudinal direction from a first blade portion 332, which will be described later. As shown in FIG. 1 , at positions corresponding to the recessed portions 411 and 421 , the restricting portion 32 is formed with recessed portions 321 that are recessed in a direction opposite to the direction in which the recessed portions 411 and 421 are recessed. there is Moreover, the restricting portion 32 further has a front end portion 322 and a rear end portion 323 .

A blade portion is formed at the tip of the cutter body 31, and the blade portions are a first blade portion 332, a second blade portion 333, and a blade edge 331 positioned between the first blade portion 332 and the second blade portion 333. Configured. The blade has a tapered shape. As described above, since the cutter 3 is formed by injection molding, the blade portion can be easily formed by the matching surface of the mold. As shown in FIGS. 3 and 5 , the distal end portion 322 of the restricting portion 32 protrudes in the longitudinal direction compared to the first blade portion 332 , so when the cutter 3 is used to unpack the packing box, the tip portion 322 of the packing box is When the user inserts the blade into a portion of the stuck adhesive tape or the like that needs to be unsealed and pierces the adhesive tape with the cutting edge 331, the blade enters the packing box, and the tip 322 of the regulating portion 32 is packed. abut the box. As a result, the depth of entry of the cutter 3 into the packing box is restricted, so damage to the items to be packed in the packing box can be prevented.

A step 38 is formed between the second blade portion 333 and the non-blade region of the cutter body 31, and the second blade portion 333 is recessed from the non-blade region. Therefore, at the time of use, the user inserts the blade portion into a portion where the adhesive tape or the like attached to the packaging box needs to be opened, pierces the adhesive tape with the blade edge 331, and then inserts the second blade portion 333 into the packaging box. As a result of putting it inside, even if the tip 322 of the regulating portion 32 does not come into contact with the packaging box (that is, even if the cutting depth of the cutter 3 is not limited by the tip 322 of the regulating portion 32, ), the presence of the step 38 can prevent the blade from further entering the packing box, thereby preventing damage to the items to be packed in the packing box.

Next, the part of the holding mechanism for attaching the cutter 3 to the case and for holding the cutter 3 will be described. As shown in FIG. 3, the rear end of the cutter body 31 is formed with a substantially circular connecting portion 3a. A hollow cylindrical portion 37 is formed in the central portion on the connecting portion 3a side, and a hole 371 is formed inside the cylindrical portion 37 . As shown in FIGS. 4 and 5, the cutter 3 is rotatably attached to the shaft 422 of the second case 42 through the hole 371. As shown in FIGS. Axis 422 is parallel to the axis of rotation of the rollers of the applicator section previously described. Since both rotation axes are parallel, it is easy to operate during use. A reinforcing portion 36 is formed between the cylindrical portion 37 and the restricting portion 32 . A protrusion 34 and a protrusion 35 protruding outward are formed on the side surface of the connecting portion 3a. As the cutter 3 rotates, the protrusions 34 and 35 come into contact with a stopper portion 423 formed on the second case 42 or go beyond the stopper portion 423 . As shown in FIG. 4, the projection 35 is used to limit the movement of the cutter 3 to the usage posture in the storage posture. As shown in FIG. 5, the projection 34 is used to limit the movement of the cutter 3 to the retracted posture in the use posture. As a result, the cutter 3 can be held in the usage posture shown in FIG. 1 and the storage posture shown in FIG. Further, although not shown, the second case 42 is further formed with an engaging portion for engaging with the rear end portion 323 of the restricting portion 32, and the engaging portion serves as a stopper for the projection 34 of the cutter 3. It is used to limit excessive movement in the opening direction after crossing the portion 423 . Thereby, the cutter 3 can be held in an appropriate usage posture.

At positions corresponding to the projections 34 and 35 of the connecting portion 3a, arc-shaped lightening portions 39 similar to the external shape of the connecting portion 3a are formed. By providing the lightening portion 39, the user does not need to apply a large force when the protrusions 34 and 35 go over the stopper portion 423 by operating the grip portion by the user, and the protrusion 34 or the protrusion 35 of the connecting portion 3a does not need to be applied. , the protrusion 34 or the protrusion 35 goes over the stopper portion 423 by deformation of the portion close to , and the opening and closing operation of the cutter 3 can be facilitated.

The cutter 3 can take a use posture and a storage posture with respect to the case. Next, the usage posture and the storage posture will be described.

As shown in FIGS. 1 and 4 , in the retracted posture, the restricting portion 32 is stored in the recess 414 formed in the first case 41 and the recess 424 formed in the second case 42 . In this state, the surface of the regulating portion 32 is substantially coincident with the surface of the case except for the recessed portion 321, so that the outer shape of the unpacking tool as a whole can be kept substantially coincident in the storage posture, and the appearance is improved. beautiful. The cutter body 31 is inserted into a groove 43 formed between the first case 41 and the second case 42 and accommodated inside the cases. In addition, since the projection 35 engages with the stopper portion 423 in the stored posture, even if the unpacking tool is shaken while being stored in another container and carried, the cutter 3 is opened unexpectedly. The cutter 3 does not open unexpectedly.

In addition, as shown in FIG. 1 , in the storage position, the depressions 411 and 421 and the depressions 321 allow the user to place a finger between the regulation section 32 and the first case 41 and the second case 42 . A space is formed for gripping 32 . As a result, the user can easily pull out the cutter 3 by gripping the restricting portion 32 and change the cutter 3 from the retracted posture to the use state. In addition, since the space for the user to grip the restricting portion 32 does not overlap with the blade portion of the cutter 3, the user grips the restricting portion 32, pulls out the cutter 3, and shifts from the storage posture to the use posture. Since it is difficult to touch the blade when doing so, the operation is performed more safely.

As shown in FIGS. 2 and 5, in the use posture, the projection 34 is locked by the stopper portion 423, so that the cutter 3 is prevented from moving to the storage posture, and the cutter 3 can be held in the use posture. can. Further, by engaging the rear end portion 323 of the restricting portion 32 with an engaging portion (not shown) of the second case 42, it is possible to restrict the cutter 3 from opening excessively in the opening direction. Therefore, the cutter 3 can be kept in an appropriate use posture.

Next, the case of using the unpacking tool will be described. When the unpacking tool is in the stored posture, the depressions 411, 421, and 321 allow the user to push the regulation portion 32 between the regulation portion 32 and the first case 41 and the second case 42 with his fingers. Since the holding space is formed, the user can easily hold the restricting portion 32 by the space. When the projection 35 goes over the stopper portion 423, the cutter 3 moves to the use posture, and when the projection 34 goes over the stopper portion 423, the cutter 3 is held in an appropriate use posture. In the usage posture, when the user inserts the blade portion into a portion where the adhesive tape or the like attached to the packaging box needs to be opened, and pierces the adhesive tape with the cutting edge 331, the tip portion 322 of the regulating portion 32 is pushed into the packaging box. The abutment limits the further entry of the cutter 3 into the packaging box. This can prevent the cutter 3 from damaging the articles in the packing box. The user unpacks the packing box by moving the cutter along the gap sealed with the adhesive tape of the packing box while keeping the cutting edge 331 inserted into the packing box. Although the case of unpacking the packing box using the unpacking tool has been described above, the unpacking tool can also be used to unpack parcels in other packaging forms, such as bag-like parcels.

After completing the unpacking operation of the box, when the user grips the recessed portion 321 of the regulating portion 32 and rotates the cutter 3 to the closed posture, the projections 34 and 35 go over the stopper portion 423 , thereby opening the cutter 3 . is accommodated in the case and assumes the storage posture. As described above, since the protrusion 35 is locked by the stopper portion 423, it is possible to prevent the cutter 3 from opening unexpectedly, thus ensuring safety when storing the unpacking tool in the pen case or bag. sexuality increases.
