It is the image which showed a mode that the to-be-opened thing was actually cut | disconnected with the cutter for opening.

  Hereinafter, the present invention will be described based on the embodiments shown in the drawings, but the present invention is not limited to the following specific embodiments. In the drawings, the same reference numerals are used for the same or corresponding elements.

  As shown in FIGS. 1 to 3, the opening cutter (hereinafter also simply referred to as “cutter”) 1 of the present embodiment is provided on the first member 11 provided with the first surface 11 </ b> A and the first surface 11 </ b> A. The distance between the first and second surfaces 11A and 12A is reduced while connecting the second member 12 provided with the opposing second surface 12A and the ends 11B and 12B of the first and second members 11 and 12 to each other. A main body 10 having a connecting portion 13 capable of elastically deforming at least one of the first and second members 11 and 12.

  In the illustrated example, the first member 11 corresponds to an upper member (portion) of the main body 10, and the second member 12 corresponds to a lower member (portion) of the main body 10. The main body 10 in which the first and second members 11 and 12 are connected by the connecting member 13 has a shape in which the letter “U” of the alphabet is directed sideways.

  Further, the first member 11 is provided with a blade 20, and the tip 20 </ b> A is provided so as to protrude from the first surface 11 </ b> A toward the second surface 12 </ b> A of the second member 12. More specifically, the first member 11 is formed with an opening 14 (through hole 14 in the figure) for accommodating the root portion 20B of the blade 20.

  As shown in FIG. 1, the through-hole 14 may house the blade pressing component 21 in addition to the blade 20, thereby firmly fixing the root portion 20 </ b> B of the blade 20. The blade pressing component 21 may have a lid portion 21A that covers the blade 20 from the upper side and covers the through hole 14 from the upper side. Since this lid portion 21A can be seen from the outside of the first member 11, it is easy to confirm (specify) the position of the blade 20, and it is possible to obtain an additional advantage that it is easy to aim at the cutting position at the time of cutting.

  Moreover, 11 A of 1st surfaces including the installation location of the blade 20 incline so that it may curve a little upward toward the front-end | tip 11C of the 1st member 11, and the front-end | tip 20A of the blade 20 is orthogonal to the inclined surface 11S. It is preferable to protrude. Thus, when the first member 11 and the second member 12 are brought close to each other to cut the material to be opened 2 with the blade 20, the inclined surface 11S is oriented substantially horizontally with the second surface 12A of the second member 12, The tip 20A of the blade 20 comes into contact (i.e., pierces) with the object to be opened 2 vertically.

  It should be noted that the cutter 1 of the present invention further includes a slide part 30 that can slide on the second surface 12A from the first position to the second position on the second member 12 having the second surface 12A. . 4 is a diagram for explaining how to cut the blade 20 at the first position, while FIG. 5 is a diagram for explaining how to cut the blade 20 at the second position. In particular, FIGS. 4B and 5B show a cutter that is broken along the longitudinal direction at the center position in the width direction of the cutter 1 with the cutter 1 set at the first position and the second position, respectively. 1 is a cross-sectional view.

  Specifically, in the first position, the tip 20A of the blade 20 can contact a portion (a raised portion described later) 31 of the slide part 30 by elastic deformation of the first member 11 or the second member 12, while the first member 11 or the second member 12 is elastically deformed. In the second position, the blade 20 can move forward relative to the tip 32 of the slide part 30. That is, when the first and second members 11, 12 are brought close to each other at the second position, the portion 31 of the slide part 30 comes into contact with the first surface 11 </ b> A of the first member 11. The blade 20 positioned in front of the front end 32 moves downward from the slide part 30 by the amount of protrusion of the front end 20A from the first surface 11A, and eventually pierces the object to be opened 2 by the amount of protrusion. .

  In addition, it is preferable that the slide part 30 is provided in the 2nd member 12 so that attachment or detachment is possible like the example of illustration. As a result, the main body 10 and the slide part 30 can be separately cleaned all over, so that all dirt and moisture that easily adhere between the members 10 and 30 in the assembled state can be removed. Therefore, it is preferable in terms of hygiene.

  As described above, the sliding and attaching / detaching functions generated by the slide part 30 can be realized by, for example, providing the following structure to the slide part 30 or the second member 12.

  As shown in FIG. 1B, the slide part 30 includes a flat plate-like base portion 33, and arm portions 34A and 34B extending downward from both ends of the base portion 33 (both ends in a direction crossing the sliding direction), Rails 35A and 35B provided on the inner wall surfaces where the arm portions 34A and 34B face each other are provided. The arm portions 34A and 34B and the rails 35A and 35B extend along the longitudinal direction of the base portion 33 (that is, the sliding direction of the slide part 30). On the other hand, guide grooves 15A and 15B are provided on both side walls of the second member 12 (only one side wall 12D is shown in FIG. 1). The slide part 30 having the above-described configuration forms a space that can slide along the second member 12 while accommodating the second member 12.

  Furthermore, the slide part 30 has an opening 37 on the base end 38 side opposite to the tip 32 (that is, the portion in the downward direction from the base 33 is a notch) as in the illustrated example. It is preferable that the second member 12 can be inserted and removed from the opening 37. In other words, the slide part 30 can be detachably connected to the second member 12.

  Moreover, it is preferable that the slide part 30 and the second member 12 are provided with restriction means capable of temporarily fixing the slide part 30 at least at the first position and the second position. As a preferred example of the restricting means, as shown in FIG. 1, for example, as the restricting means on the second member 12 side, the convex portion 16 is formed on the second surface 12A, while the restricting means on the slide part 30 side. As a result, an engaging member 36 that can engage with the convex portion 16 is formed.

  As shown in FIGS. 4 and 5, only the base end 36 </ b> B is a slide part so that the distal end 36 </ b> A can move (elastically deform) most vertically (that is, vertically) with respect to the second surface 12 </ b> A. The structure connected to 30 is preferable. As a result, when the slide part 30 is slid on the second member 12 or attached / detached, a sound that the tip 36A of the engagement member 36 is fitted to the convex portion 16 is generated, or the engagement is released. Since the joint member 36 is struck by the second surface 12A due to its elastic force, the position and attachment / detachment of the slide part 30 can be confirmed also by these sounds.

  Moreover, you may make it form many convex parts 16 on the 2nd surface 12A of the 2nd member 12 along the longitudinal direction, or form the groove | channel (not shown) continuous in the longitudinal direction. As a result, the engaging members 36 are sequentially and elastically engaged with these convex portions 16 and grooves, and the slide part 30 is temporarily fixed at a desired position other than the first and second positions. Will be able to.

(Usage method and operation of the cutter 1 of this embodiment)
Next, the usage method and operation of the cutter 1 having the above configuration will be described.

1. When the material to be opened is a food packaging bag or envelope (use in the first position)
(1) When the material to be opened 2 (2A) is a food packaging bag or envelope, first, the slide part 30 having the above configuration is slid on the second surface 12A (in a state where the slide part 30 is pulled out from the connecting portion 13). ), And fixed (temporarily fixed) to the first position (see FIG. 4A).
(2) Next, a packaging bag or an envelope, which is an object to be opened 2A, is inserted between the first member 11 and the second member 12, and these members 11 and 12 are held by a finger holding these members 11 and 12. The objects to be opened 2A are sandwiched close to each other. Then, the tip 20A of the blade 20 protruding from the first surface 11A comes into local contact (point contact) with the material to be opened 2A placed on the part 31 of the second member 12 (FIG. 4 ( see b)).
(3) Then, as shown in FIG. 6A, the cutter 1 is pulled in the lateral direction (that is, the direction intersecting the insertion direction of the material to be opened 2A) while the material to be opened 2A is sandwiched. As a result, the position where the tip 20A contacts the object to be opened 2A moves, and is opened (cut) corresponding to the amount of movement.

  In the slide part 30, the shape of the portion 31 with which the tip 20 </ b> A of the blade 20 abuts is higher than the other portion toward the first member 11 (in the illustrated example, the cross section in the direction crossing the sliding direction is half (Circular shape) is preferable. Thereby, the local contact (point contact or line contact) of the tip 20A to the portion 31 at the time of cutting can be ensured, and the cutter 1 with always good sharpness can be provided.

2. When the material to be opened is a package of tofu or jelly (use in the second position)
When the material to be opened 2 (2B) is a packaging package that accommodates tofu, jelly, pudding, and so on, the cutter 1 of the present invention is used as follows. As this packaging package, as shown in FIG. 5 (b), a side wall 4 provided with a bottom portion 3 having a rectangular or circular shape, and a flange portion 5 standing from the bottom portion 3 and projecting outward at the upper end, A well-known container body 2B which is composed of an upper surface seal 6 and is commercially available is assumed. Here, the bottom part 3 and the side wall 4 are usually made of a relatively thick and strong plastic, and form a container part that can accommodate food such as tofu without losing its shape. On the other hand, the upper surface seal 6 is a thin film-like body and is bonded to the upper surface and the outer periphery of the flange portion 5.

(1) First, the slide part 30 having the above-described configuration is slid on the second surface 12A (in a contracted state toward the connecting portion 13) and fixed (temporarily fixed) to the second position (FIG. 5). (See (a)).
(2) Next, the flange portion 5 of the side wall 4 is inserted between the first member 11 and the second member 12, and the flange portion is reached until the blade 20 reaches directly above the upper surface seal 6 inside the flange portion 5. 4 is pulled in between the first and second members 11 and 12. Furthermore, these members 11 and 12 are brought close to each other by a finger holding these members 11 and 12 to sandwich the material to be opened 2B. Then, the tip 20A of the blade 20 protruding from the first surface 11A comes into contact with only one point CP of the upper surface seal 6 avoiding the relatively strong flange portion 5, and pierces and cuts from that point CP (FIG. 5 (b)).
(3) The cutter 1 is moved along the circumferential direction (for example, the lateral direction or the circumferential direction) of the flange portion 5 while the blade 20 is pierced into the article to be opened 2B. As a result, the point CP where the tip 20A contacts the object to be opened 2B (the upper surface seal 6) moves and is opened (cut) corresponding to the amount of movement (see FIG. 6B). ).

  The cutter 1 of the present invention has a distance d (not shown) between the blade 20 and the tip 32 of the slide part 30 when the first member 11 and the second member 12 are brought close to each other at the second position. It is preferable that the 2nd position is set so that it may become more than the thickness of the side wall 4 of the opening thing 2B. More preferably, when the thickness t of the side wall 4 is t, the distance d is t ≦ d ≦ (t + 3 mm).

  Accordingly, when the cutter 1 is used at the second position, the flange portion 5 is moved between the first and second members 11 and 12 until the tip 32 of the slide part 30 comes into contact with the side wall 4 below the flange portion 5. The blade 20 can be easily positioned at the most preferable cutting position CP on the upper surface seal 6 simply by pulling in. Furthermore, since the side wall 4 serves as a guide not only for positioning but also when the cutter 1 is moved along the flange portion 5, the upper surface seal 6 can be easily cut while drawing the most preferable line. Become.

  Note that even if the protruding length of the flange portion 5 is varied, the flange portion 5 is drawn into the gap between the first and second members 11 and 12, so that there is no risk that the flange portion 5 interferes with any member of the cutter 1 of the present invention.

  The cutter 1 may further include a magnet. For example, as shown in the drawing, it is preferable to provide the thin sheet-shaped magnet 18 on the bottom surface 12Z (preferably, the recess 12M) of the second member 12. Thereby, when not using the cutter 1, the cutter 1 can be affixed on metal surfaces, such as the wall of a refrigerator.

  Also, the top surface 11Z of the first member 11 and the bottom surface 12Z of the second member 12 are fingers that have shapes that match the shape of the finger and that allow the first and second members 11, 12 to be easily grasped by these fingers. It is preferable that the contact portions 17A and 17B are formed. In the illustrated example, the bottom surface 12Z of the second member 12 is formed with a recessed portion 17B that is recessed from the other portions. In the illustrated example, the most recessed portion of the recessed portion 17B extends in a direction crossing the sliding direction. Extending along. On the other hand, on the upper surface 11Z of the first member 11, an inclined portion 17A that increases as it approaches the tip 11C is formed. With this exemplary configuration, the first and second members 11 and 12 can be surely grasped and moved while fitting the thumb or index finger to the finger rests 17A and 17B.

(Modification)
As mentioned above, although the said structure of the cutter 1 of an Example was demonstrated referring drawings, this invention is not limited to this. For example, the slide part 30 may not be provided in the cutter 1, and the first member 11 may have the role / function that the slide part 30 plays.

  Specifically, the cutter 1 includes a first member 11 provided with a first surface 11A, a second member 12 provided with a second surface 12A facing the first surface 11A, and first and second members. A connecting portion 13 capable of elastically deforming at least one of the first and second members 11 and 12 so that the distance between the first and second surfaces 11A and 12A approaches while connecting the ends 11B and 12B of the members 11 and 12; The blade 20 is provided on the first member 11 so as to protrude from the first surface 11A toward the second member 12, and the following members have the following characteristics.

  That is, the first member 11 has a sliding structure (not shown) so that the blade 20 (which may include the blade 20) can be moved from the first position to the second position, and In the first position, the blade 20 can contact a part of the second member 12 by the elastic deformation, while the blade 20 moves forward of the second member 12 in the second position. Accordingly, when the first and second members 11 and 12 are brought close to each other at the second position, the portion of the second member 12 comes into contact with the first surface 11A of the first member 11, and the second The tip 20A of the blade 20 positioned in front of the member 12 moves downward from the second member 12 by the amount of protrusion from the first surface 11A, and eventually pierces the object to be opened 2 by the amount of protrusion. .

  Even with the configuration of the modified example as described above, the same function as the above-described embodiment can be achieved.

  According to the opening cutter of the present invention, it can be used not only as an opening cutter for food packaging bags and envelopes but also as an opening cutter for tofu packages, etc. It became possible to spread.

  Thus, the opening cutter of the present invention has a very high industrial utility value and industrial applicability.
