Description

[Technical Field]

[0001] This invention relates to a PP band cutter that can divide and cut PP bands along the longitudinal direction (the insertion direction of the PP band), and in particular to a handy PP band cutter that allows users to easily and safely cut PP bands to the desired narrow width. [Background technology]

[0002] PP bands come in many different width and thickness standards, allowing users to select the appropriate PP band for their intended use. However, to use a PP band with a width that is not included in the standards, users must cut the PP band in half along its length.

[0003] Patent Document 1 discloses a tape cutter that can cut and divide a tape in the longitudinal direction. The tape cutter described in Patent Document 1 has an internal space in the housing, and holds the cutter in this internal space, pressing the tape surface against the blade, thereby cutting and dividing the tape in the longitudinal direction. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3233274 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the tape cutter described in Patent Document 1 has only one blade that cuts the tape lengthwise, and cannot cut the tape into two or more pieces in one operation.In addition, the tape cutter described in Patent Document 1 is heavy and needs to be fixed to a desk or the like when in use, requiring space for operation.

[0006] The present invention has been developed in consideration of the above-mentioned problems, and aims to provide a small, lightweight, handy PP band cutter that can cut PP bands into two or more pieces in a single operation to obtain PP bands of the desired width. [Means for solving the problem]

[0007] The PP band cutter of the present invention is characterized by comprising a lower box portion and a single-opening top lid portion rotatably connected to one end of the lower box portion, a PP band pull-out portion formed on the top surface of the one end, a PP band intake portion formed on the top surface of the other end of the lower box portion in a position opposite the PP band pull-out portion, and at least one blade portion that, when the top lid is opened to one side, inserts a PP band into the PP band pull-out portion so that the PP band fits into the PP band intake portion, and then closes the top lid to cut and divide the PP band in the insertion direction. [Effects of the Invention]

[0008] This device is equipped with multiple blades that cut the PP band along its length, allowing it to be cut to the desired width with a single operation.It is also small and lightweight, so it can be held in the hand and used. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Specific embodiments of the present invention will be described in detail below. The drawings are schematic representations of the PP band cutter, its components, and its peripheral components, and the dimensions and dimensional ratios in the drawings do not necessarily correspond to the actual dimensions and dimensional ratios. Furthermore, unless otherwise specified, for convenience, directions such as up and down are indicated based on the orientation of the PP band cutter shown in Figure 1. Duplicate descriptions will be omitted where appropriate, and the same components may be assigned the same reference numerals.

[0011] Fig. 1(a) is a front perspective view of a PP band cutter 100 according to an embodiment of the present invention, showing a state in which the top cover 20 is open on one side, and Fig. 1(b) is a rear perspective view of the PP band cutter 100 according to an embodiment of the present invention, showing a state in which the top cover 20 is closed. The PP band cutter 100 comprises a lower box part 10 made of resin that is substantially rectangular in plan view, and a top cover part 20 that is placed over the top surface 12 of the lower box part 10 and opens on one side.

[0012] The lower box section 10 has a PP band inlet 13 that protrudes from the front of the lower box section 10 and a PP band outlet 14 formed on the back of the lower box section 10 (in this specification, the front refers to the PP band inlet side, and the back refers to the PP band outlet side. Furthermore, when the back is referred to as one end, the front is referred to as the other end). The PP band inlet 13 has a rectangular trough shape when viewed from the front. When the top cover 20 is open, the trough shape of the PP band inlet 13 (open at the top) makes it easy to insert PP bands 40 (not shown) into the PP band inlet 13. The PP band outlet 14 has a horizontally elongated rectangular shape when viewed from the back, and is open on the back side of the lower box section 10.

[0013] The top surface 12 of the lower box section 10 is provided with PP band guide sections 11 that extend from both ends of the PP band intake section 13 to both ends of the PP band pull-out section 14. The PP band guide section 11 is composed of a pair of walls that protrude vertically from the top surface 12. The PP band guide section 11 is composed of a pair of approximately parallel walls, but the inside dimensions are expanded at a widened section 19. The widened section 19 makes it easier to insert the PP band 40 into the PP band intake section 13. The inside dimensions of the PP band guide section 11 are wider than the width of the PP band throughout. The PP band 40 is taken in from the PP band intake section 13, guided by the PP band guide section 11, and pulled out by the PP band pull-out section 14.

[0014] The top cover 20 has an outer edge 21 that forms part of the intake section. When the top cover 20 is closed, the outer edge 21 abuts against the PP band guide section 11 at the abutment section 15. The abutment section 15 protrudes vertically from the top surface 12. Therefore, even when the outer edge 21 and the PP band guide section 11 abut at the abutment section 15, the PP band intake section 13 is not blocked. The abutment section 15 protrudes from the top surface 12 to a height greater than the thickness of the PP band. Therefore, even when the top cover 20 is closed, it does not press against the PP band 40. The PP band guide section 11 has a raised section 16 that is higher than the abutment section 15. The raised section 16 is formed closer to the PP band pull-out section 14 than the abutment section 15, and the raised section 16 prevents the PP band 40 from climbing over the PP band guide section 11.

[0015] A cutout 22 is provided on the back surface of the top cover 20. The width of the cutout 22 is approximately the same as the PP band pull-out portion 14, but its height is much greater than the thickness of the PP band. This prevents the PP band pull-out portion 14 from being blocked even when the top cover 20 is opened to one side and moved downward.

[0016] 2 is a perspective cross-sectional view showing the top cover 20 of the PP band cutter 100 according to an embodiment of the present invention in a closed state. The top cover 20 is provided with at least one blade 23 whose cutting edge protrudes toward the lower box portion 10. The cutting edge 26 of the blade 23 is positioned so that it gradually becomes lower from the PP band intake portion 13 toward the PP band pull-out portion 14. The PP band 40 is taken in from the PP band intake portion 13 and comes into contact with the cutting edge 26 on its way to the PP band pull-out portion 14, whereby the PP band 40 is cut and divided along the longitudinal direction (insertion direction).

[0017] The lower box part 10 has a recess 17 below the blade 23. The recess 17 allows the cutting edge 26 to be positioned below the top surface 12, making it easier to cut and divide the PP band 40. The blade 23 is also positioned on the PP band pull-out portion 14 side of the top cover part 20. This reduces the force required to press the PP band 40 with the top cover part 20 when cutting the PP band 40. The blade 23 is also stored inside the PP band cutter 100, ensuring safety. The lower box part 10 and the top cover part 20 may be provided with a bottom finger grip 31 and a top finger grip 30. The user can grip the PP band cutter 100 with their fingers when using it, allowing for stable operation.

[0018] The top cover 20 is provided with at least one PP band holder 29 that protrudes toward the top surface 12 of the PP band guide 11. If the PP band 40 taken in from the PP band intake 13 becomes loose inside the PP band cutter 100, there is a risk that the cutting and dividing in the longitudinal direction will be inaccurate. Since the PP band holder 29 protrudes to a low position close to the top surface 12, closing the top cover 20 presses the PP band 40, preventing it from sagging.

[0019] FIG. 3 is an exploded perspective view showing the blade receiving slot 24 of the PP band cutter 100 according to an embodiment of the present invention. Reinforcing walls 27 and 28 are provided inside the top cover 20 in a direction perpendicular to the feeding direction of the PP band 40. The feeding direction refers to the direction (insertion direction) from the PP band intake 13 to the PP band pull-out 14. Blade receiving slots 24 are provided symmetrically on opposing sides of the reinforcing walls 27 and 28. The blade receiving slot 24 of the reinforcing wall 27 and the blade receiving slot 24 of the opposing reinforcing wall 28 are aligned on the same line parallel to the feeding direction of the PP band 40. Therefore, the blade receiving slot 24 holds the blade 23 parallel to the feeding direction of the PP band 40. Since multiple blade receiving slots 24 are provided in a direction perpendicular to the feeding direction of the PP band 40, multiple blades 23 can be accommodated inside the top cover 20.

[0020] 4 shows a PP band 40 cut and divided by a PP band cutter 100 according to an embodiment of the present invention. FIG. 4(a) shows a case where one blade 23 is accommodated in the blade accommodation slot 24, dividing the PP band into two. The PP band 40 is taken in through the PP band intake section 13 and sent to the PP band pull-out section 14, where it is divided into two by the blade 23 and pulled out from the PP band pull-out section 14. FIG. 4(b) shows a case where two blades 23 are accommodated in the blade accommodation slot 24, where it is divided into three. The PP band 40 is taken in through the PP band intake section 13 and sent to the PP band pull-out section 14, where it is divided into three by the multiple blades 23 and pulled out from the PP band pull-out section 14.

[0021] FIG. 5 is an exploded view showing the single-opening mechanism between the bottom box part 10 and the top lid part 20. Spherical pivots 18 are provided on both sides of the rear side of the bottom box part 10, and through-holes 25 corresponding to the spherical pivots 18 are provided in the top lid part 20. The bottom box part 10 and the top lid part 20 are made of flexible resin and employ a snap-fit ​​structure that allows for disassembly and reassembly through elastic deformation. The through-holes 25 in the top lid part 20 temporarily elastically deform to pivotally connect with the spherical pivots 18 of the bottom box part 10, thereby allowing the top lid part 20 to open in one direction. Note that the method of connecting the bottom box part 10 and the top lid part 20 to open in one direction is not limited to a snap-fit ​​structure or a spherical pivot. A rotating shaft (not shown) may be provided instead of the spherical pivots 18, or a thin-walled hinge (not shown) that connects the bottom box part 10 and the top lid part 20 with a thin-walled resin may be used.

[0022] Next, we will explain how to use the PP band cutter 100. Figure 6 is an explanatory diagram of how the PP band 40 is cut and divided along its length using the PP band cutter 100 according to an embodiment of the present invention. First, the PP band 40 is cut to a predetermined length. Next, the top cover 20 is opened to one side, and the PP band 40 is inserted through the PP band inlet 13. The PP band 40 is pulled out several centimeters from the PP band pull-out section 14, and the open top cover 20 is then closed. At this time, the blade 23 bites into the PP band 40. In this state, the PP band 40 is pulled out by pinching the portion protruding from the PP band pull-out section 14 with your fingers. The PP band 40 pulled out from the PP band pull-out section 14 has been cut and divided along its length. Furthermore, the PP band cutter 100 according to an embodiment of the present invention can have additional blades 23. By adding additional blades 23 to the available blade receiving slots 24, the number of divisions can be increased to three, four, or more.

[0023] As described above, the PP band cutter 100 according to the embodiment of the present invention is equipped with multiple blades 23 that cut the PP band 40 in the longitudinal direction, allowing it to cut the band into more than two sections in one operation, making it easy to create PP bands of the desired width (narrow width). Furthermore, because it is small and lightweight, it can be held in the hand and used anywhere. [Explanation of symbols]
