Description

[Technical Field]

[0001] The present invention relates to a tape cutter that pulls out and cuts the end of a roll of tape. [Background technology]

[0002] A portable holding and cutting device is known that has a cutting blade on an openable lid to prevent dirt and other debris from adhering to the device and to prevent damage to hands and clothing during transport (see Patent Document 1). A tape cutter is also known that has a cover that covers the cutting part (see Patent Document 2). Another adhesive tape cutting device is known that has a folded part that allows the tape to be held when being pulled out (see Patent Document 3). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-61362 [Patent Document 2] Japanese Patent Application Laid-Open No. 2004-345767 [Patent Document 3] Japanese Patent Application Publication No. 9-25045 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above Patent Documents 1 and 2, although consideration is given to safety when carried, there is no fold or the like for pulling out the tape, which may result in a lack of convenience when used and may also cause hygiene problems such as smearing with fingerprints.On the other hand, in the above Patent Document 3, the end of the tape, including the part where the fold is formed, is exposed, which may also cause hygiene problems.

[0005] The present invention has been made in consideration of the above points, and aims to provide a tape cutter that is convenient when cutting tape while also taking into consideration hygiene and safety. [Means for solving the problem]

[0006] To achieve the above objective, a tape cutter includes a storage section for storing the tape, a cutter mechanism having a cutting blade that cuts the tape to form a tape end, and a movable section that supports the cutting blade and opens and closes, and a sliding shutter that forms a fold at the tape end while sealing the cutting blade when the cutter mechanism is closed.

[0007] In the above-mentioned tape cutter, the cutter mechanism has a movable part that supports the cutting blade that opens and closes, and a sliding shutter that forms a fold at the end of the tape while sealing off the cutting blade when the cutter mechanism is closed. In this case, the fold at the end of the tape is formed as the cutter mechanism closes, making it easier to remove the tape the next time it is cut, which improves convenience, and by forming the fold and closing the area together with the cutting blade with the shutter, it is possible to take into consideration hygiene and safety.

[0008] In a specific aspect of the present invention, the cutter mechanism has a protrusion disposed opposite the adhesive surface of the tape end. In this case, when forming the fold, the protrusion can maintain the state in which the tape end is folded in a desired direction. More specifically, it can prevent the tape end from bending in the direction opposite to the direction in which the adhesive surface of the tape end is bonded.

[0009] In another aspect of the present invention, the protrusion supports the tape end between a first support portion that supports the tape end on the cutter mechanism side and a second support portion that supports the tape end on the storage section side, in which case a fold can be formed between the first support portion and the second support portion.

[0010] In yet another aspect of the present invention, the second support portion is a stop plate that is provided in the storage portion and positions the cutter mechanism within the storage portion when the cutter mechanism is stored. In this case, the stop plate that functions as the second support portion can regulate the position of the cutter mechanism when the cutter mechanism is stored.

[0011] In yet another aspect of the present invention, the second support portion has a groove that accommodates the protrusion when the cutter mechanism is retracted. In this case, the protrusion can be retracted accurately.

[0012] In yet another aspect of the present invention, the storage section is a cylindrical member conforming to the shape of the tape, and in the cutter mechanism, the movable section is a plate-like member having an attachment section for attaching a cutting blade at one end and a rotation support section for opening and closing at the other end, and curved along the shape of the cylindrical side surface of the storage section. In this case, the device can be made small and suitable for portability.

[0013] In yet another aspect of the present invention, the shutter slides along the cylindrical side surface of the storage section, and when the cutter mechanism closes, the shutter covers the attachment section together with the cutting blade from the outside along the cylindrical side surface of the storage section, sealing the tape end and forming a fold. In this case, the fold is formed easily and reliably, and the fold can be extended in a direction that makes it easy to pull out the tape.

[0014] In yet another aspect of the present invention, the storage section has a storage width corresponding to the tape width of the surgical tape used as the tape. In this case, the storage section can be sized to be suitable for use with the surgical tape, and is excellent in terms of speed and hygiene in medical settings.

[0015] In yet another aspect of the present invention, the storage section is transparent or translucent. In this case, the storage status inside the storage section, such as the remaining amount of tape, can be visually confirmed from outside the tape cutter. [Brief explanation of the drawings]

[0017] An example of a tape cutter according to an embodiment will be described below with reference to Fig. 1 etc. Figs. 1(A) to 1(E) are diagrams showing the external appearance of a tape cutter 100 according to an embodiment with the shutter closed. Of these, Fig. 1(A) is a perspective view of the tape cutter 100 as seen from one direction (closer to the front), Fig. 1(B) is a plan view, Fig. 1(C) is a side view, Fig. 1(D) is a rear view, and Fig. 1(E) is a perspective view as seen from another direction (closer to the rear).

[0018] 2(A) to 2(F), Fig. 2(A) to 2(E) are views showing the external appearance when the shutter is open and the cutter mechanism is closed, and correspond to Fig. 1(A) to 1(E), respectively. Fig. 2(F) is a view corresponding to Fig. 2(A), and shows the cutting blade BL, which is the cutter blade omitted in Fig. 2(A), attached to the cutter mechanism 20.

[0019] Furthermore, among Figures 3(A) to 3(F), Figures 3(A) to 3(E) are diagrams showing the external appearance when the shutter and cutter mechanism are open, and correspond to Figures 1(A) to 1(E), respectively. Note that Figure 3(F) is a diagram corresponding to Figure 3(A), and shows the tape cutter 100 with the tape TA attached (stored).

[0020] 1 and other figures, the tape cutter 100 of this embodiment includes a storage section 10 that stores a tape TA (see FIG. 3(F)), a cutter mechanism 20 for cutting the tape TA, and a shutter 30 for sealing the ends of the tape TA and the cutter mechanism 20. Note that, for each part of the tape cutter 100, it is conceivable that all parts except the cutting blade BL are made of resin molded parts, with the cutting blade BL being made of metal, but other materials may also be used.

[0021] When the tape cutter 100 is moved from a closed state (shutter closed state) of the shutter 30 shown in Fig. 1 to an open state (shutter open state) of the shutter 30 shown in Fig. 2 by sliding the shutter 30, the cutter mechanism 20 stored in the storage unit 10 opens by its own weight, and the state shown in Fig. 3 (cutter mechanism open state) is reached. Therefore, to return from the state shown in Fig. 3 to the state shown in Fig. 1, the user first uses a finger or the like to push up the cutter mechanism 20 from below to store it in the storage unit 10, and then, while maintaining that state, slides the shutter 30 downward.

[0022] The storage section 10, the cutter mechanism 20, and the shutter 30 that constitute the tape cutter 100 will be outlined below.

[0023] First, the storage unit 10 is composed of a main case 11 and a main cover 12. To store the tape TA, the storage unit 10 is a cylindrical member corresponding to the shape of the tape (cylindrical roll of tape), and as shown in FIG. 1(B), has a storage width WD corresponding to the width of the tape. Here, the tape TA is assumed to be, for example, surgical tape (e.g., about 25 mm), and the storage width WD is set accordingly. Furthermore, the storage unit 10 can be made, for example, transparent or translucent by selecting an appropriate material.

[0024] The storage unit 10 is also fitted with a cutter mechanism 20 and a shutter 30 so that they can be opened and closed as described above. The cylindrical shape mentioned here is not limited to a shape with a perfect circle (a complete circle without distortion) at the bottom, but also includes an elliptical shape and an oval shape as shown in the figure. As shown, the storage unit 10 has a hole HL in the center, and a recess DE is formed below the cutter mechanism 20. The structure of the storage unit 10 will be described in more detail with reference to FIGS. 4 to 6.

[0025] Next, the cutter mechanism 20 is composed of a movable part MV and a cutting blade BL, as shown in Figures 2(A), 2(F), 3(A), etc. The above-mentioned parts constituting the cutter mechanism 20 also constitute a cutter part CT that forms a new tape end TG as the tape TA is cut. That is, the cutter part CT is formed by attaching the cutting blade BL to the lid LI at one end of the movable part MV, as shown in Figure 2(F).

[0026] On the other hand, the movable part MV is made up of a plate-like member curved along the side of the storage part 10, and while supporting the cutter part CT formed on the tip side as described above, it opens and closes around the base side as an axis as shown in Figures 2(A), 3(A), etc. Also, as shown in Figures 2(A), 3(A), etc., the movable part MV has a protrusion part TP arranged opposite the adhesive surface AS of the tape end part TG (see Figure 3(F)). The configuration of the cutter mechanism 20 will be described in more detail with reference to Figures 7 and 8.

[0027] The shutter 30 is a member having a U-shaped cross section, which is integrally formed from a curved plate-like member that slides along the side of the storage section 10 and a pair of plate-like members that extend from both sides of the plate-like member along the plane of the storage section 10. The configuration of the shutter 30 will be described in more detail with reference to FIG. 9.

[0028] The tape cutter 100 described above is sized to be held in one hand. When in use, the user places their middle finger in the depression DE and holds the tape storage unit 10 in their palm, sliding the shutter 30 with their thumb to open or close the shutter 30. In this case, as the shutter 30 opens, the cutter mechanism 20 opens under its own weight, transitioning from the state shown in FIG. 2 to the state shown in FIG. 3. To close the cutter mechanism 20, the user rotates the cutter mechanism 20 from below with their index finger in a direction lifting it into the tape storage unit 10, and then slides the shutter 30 with their thumb to close it, thereby retracting the cutter mechanism 20 and the tape TA into the tape storage unit 10. In other words, the state shown in FIG. 1 can be restored. In this way, the user can perform a series of opening and closing operations with one hand.

[0029] In the tape cutter 100 of this embodiment, during the series of insertion and removal operations (operations) described above, when the cutter mechanism 20 is closed, the shutter 30 seals the cutting blade BL while forming a fold in the tape end TG. This makes it easier to remove the tape cutter 100 the next time the tape is cut, improving convenience. In this case, the tape cutter 100 also takes into consideration hygiene and safety by forming the fold and closing the fold along with the cutting blade BL of the cutter unit CT with the shutter 30. The above embodiment will be described in detail below with reference to FIGS. 10 and 11.

[0030] An example configuration of the storage unit 10 will be described in more detail below with reference to Fig. 4 and other figures. Fig. 4 is an exploded perspective view for explaining the configuration of the storage unit 10. Fig. 5(A) is a right side view showing the main body case 11 of the storage unit 10, Fig. 5(B) is a front view, and Fig. 5(C) is a left side view. Fig. 6(A) is a right side view showing the main body cover 12 of the storage unit 10, Fig. 6(B) is a front view, and Fig. 6(C) is a left side view.

[0031] As described above, the storage unit 10 is composed of the main case 11 and the main cover 12. As shown in FIG. 4, for example, the main case 11 has a space for storing a roll of tape TA (see FIG. 3(F), etc.), such as surgical tape, around the location where the hole HLa, which will become the hole HL (see FIG. 1, etc.), is formed. After storing the tape TA in the space in the main case 11, the main cover 12 is attached to the main case 11, so that the storage unit 10 can store and hold the tape TA in a rotatable state. The main cover 12 has a hole HLb that corresponds to the hole HLa in the main case 11.

[0032] As described above, the storage section 10 is attached while allowing the cutter mechanism 20 to be opened and closed and the shutter 30 to be slid.

[0033] To achieve the above-described configuration, the main body case 11 includes a rotating shaft AX, a stopper plate SB, and a slide groove SLa, as shown in Figures 4 and 5(A) to 5(C). The main body cover 12 includes a rotating shaft hole AXh and a slide groove SLb, as shown in Figures 4 and 6(A) to 6(C).

[0034] The rotation axis AX is a shaft member that rotatably supports the base side of the cutter mechanism 20 (see FIG. 2, etc.). As will be described in detail later, the cutter mechanism 20 is provided with an insertion hole SS (see FIG. 7) through which the rotation axis AX is inserted. The rotation axis AX cooperates with the rotation axis hole AXh to hold the cutter mechanism 20 in an inserted state.

[0035] The stop plate SB is a plate-like member curved to fit the curved shape of the cutter mechanism 20, and is provided at a predetermined position inside the storage unit 10. When the cutter mechanism 20 is stored inside the storage unit 10 as it closes, it prevents the cutter mechanism 20 from moving further inside the storage unit 10 than necessary. That is, the stop plate SB is provided in the storage unit 10 and positions the cutter mechanism 20 within the storage unit 10 when it is stored. The stop plate SB also supports the tape end TG at its top. More specifically, as can be seen from FIGS. 3(A) and 3(F), the tape end TG is supported by the top of the cutter mechanism 20 and the top of the stop plate SB. Here, the top of the cutter mechanism 20 that supports the tape end TG on the cutter mechanism 20 side is referred to as the first support portion SU1, and the top of the stop plate SB that supports the tape end TG on the storage unit 10 side is referred to as the second support portion SU2.

[0036] Furthermore, the stop plate SB has a groove DT in the center at the position of the second support portion SU2 that forms the top. In other words, the second support portion SU2 has the groove DT. The groove DT is provided at a position corresponding to the protrusion TP (see FIG. 2, etc.) of the cutter mechanism 20, and accommodates the protrusion TP when the cutter mechanism 20 is stored inside the storage portion 10.

[0037] 4 etc., the slide grooves SLa and SLb of the storage unit 10 are configured as a pair and extend on the plane of the storage unit 10 so as to form a curved groove along the side surface of the storage unit 10. The shutter 30 is provided with fitting claws FT (see FIG. 9) for fitting into the slide grooves SLa and SLb, and by fitting the fitting claws FT into the slide grooves SLa and SLb, the shutter 30 is fitted in a state in which it can slide along the side surface of the storage unit 10.

[0038] In addition to the above, the recess DEa provided in the main body case 11 and the recess DEb provided in the main body cover 12 form a depression DE (see FIG. 1, etc.).

[0039] The cutter mechanism 20 will be described below with reference to Fig. 7 etc. Fig. 7(A) to Fig. 7(C) show the movable part MV, which is the cutter part main body of the cutter mechanism 20, with Fig. 7(A) being a perspective view of the movable part MV, Fig. 7(B) being a side view, and Fig. 7(C) being a front view of the top side of the cutter mechanism 20 (movable part MV).

[0040] The movable part MV includes the projection part TP already described, as well as a plate-like member CP, a rotation support part RS, and a mounting part PS.

[0041] The plate-like member CP is a member that constitutes the main part of the movable part MV, and is curved along the side surface of the storage part .

[0042] The rotation support part RS constitutes the base side of the plate-like member CP and has an insertion hole SS formed therein. By passing the insertion hole SS through a rotation axis AX (see FIG. 4, etc.) provided in the storage part 10, the movable part MV is attached to the storage part 10 in a state where it can rotate about the rotation axis AX.

[0043] The mounting portion PS is a recess for mounting the cutting blade BL (see FIG. 2(F)). More specifically, the cutting blade BL (see FIG. 2(F)) is mounted and fixed in a predetermined position by sandwiching it between the mounting portion PS and a cover LI (cutter unit cover) which will be described later with reference to FIG. 8. For this purpose, the mounting portion PS is provided with a mounting hole CC.

[0044] As described above, the movable part MV is composed of a plate-shaped member CP curved to follow the shape of the cylindrical side surface of the storage section 10, and the plate-shaped member CP has an attachment part PS at one end for attaching the cutting blade BL, and a rotation support part RS for opening and closing at the other end.

[0045] Hereinafter, with reference to FIG. 8, an example configuration of the lid LI (cutter unit lid) of the mounting part PS for mounting the cutting blade BL (see FIG. 2(F)) to the movable part MV as the cutter unit main body will be described. FIGS. 8(A) to 8(D) show the lid LI of the cutter mechanism 20, with FIG. 8(A) being a perspective view of the lid LI, FIG. 8(B) being a plan view, FIG. 8(C) being a front view, and FIG. 8(D) being a side view. The lid LI has a protrusion CV at a predetermined position on the plate-shaped main body part LIp. The protrusion CV is provided at a position corresponding to the mounting hole CC shown in FIG. 7(A) etc., and when the lid LI is mounted to the mounting part PS and the cutting blade BL is fixed therebetween, the protrusion CV fits into the corresponding mounting hole CC.

[0046] The shutter 30 will be described below with reference to Fig. 9. Fig. 9(A) to Fig. 9(E) show the shutter 30, with Fig. 9(A) being a perspective view of the shutter 30, Fig. 9(B) being a front view, Fig. 9(C) being a side view, Fig. 9(D) being a bottom view, and Fig. 9(E) being a cross-sectional side view taken along line XX in Fig. 9(B).

[0047] As shown in the figure, the shutter 30 is composed of a sealing portion CO and a pair of fitting portions ATa and ATb.

[0048] The sealing portion CO is a curved plate-like member that slides along the side surface of the storage portion 10 (see FIG. 1, etc.). Meanwhile, the pair of fitting portions ATa, ATb extend from both sides of the sealing portion CO along the flat surface of the cylindrical storage portion 10. The pair of fitting portions ATa, ATb are provided with fitting claws FT, FT, ... on the inner surface of the pair of fitting portions ATa, ATb, respectively, for fitting into the corresponding slide grooves SLa and SLb (see FIGS. 4 to 6). That is, when each fitting claw FT fits into the corresponding slide groove SLa, SLb, the shutter 30 performs a sliding opening and closing operation, as described with reference to FIGS. 2 to 4, etc.

[0049] The sealing part CO is also provided with a pressing part PP against which the user's finger (supposed to be a thumb) is pressed to perform the opening and closing operation by sliding as described above. The pressing part PP is a convex part that extends in the width direction, i.e., along the storage width WD (see FIG. 1(B), etc.) for storing the tape TA, at the position of the sealing part CO that is farthest from the cutter mechanism 20.

[0050] Hereinafter, a series of operations (repeated operations) of the tape cutter will be described with reference to FIG. 10 and other figures.

[0051] Figures 10(A) to 10(F) are perspective views showing a series of operations of the tape cutter 100. Figures 11(A) to 11(D) are conceptual side views showing, among the operations of Figures 10(A) to 10(F), in particular, the formation of the fold LP accompanying the operation of the tape cutter 100.

[0052] 10(A) to 10(F) show a series of operations that are repeated in the order indicated by the arrows AA. First, FIG. 10(A) corresponds to the state shown in FIG. 3(F). That is, it shows the state after the tape cutter 100 has been used, but before the tape end TG or the leading end of the cutter mechanism 20 has been retracted, with both the shutter 30 and the cutter mechanism 20 open. In this state, as shown in the figure, when the cutter mechanism 20 is closed, that is, when the cutter mechanism 20 is retracted in the direction of arrow A1 and rotated in the closing direction (typically, when the user pushes the cutter mechanism 20 up from below with their index finger), as shown in FIG. 10(B), the tape end TG bends toward the outside of the tape cutter 100, that is, when the adhesive surfaces AS bend toward each other. At this point, the tape cutter 100 corresponds to the state shown in FIG. 2(A) and other figures. Thereafter, when the shutter 30 is closed, that is, when it is slid in the direction of arrow A2 (typically, the user presses the pressing portion PP of the shutter 30 downward with their thumb), this action causes a fold LP to be formed at the tape end TG while sealing the cutting blade BL (see FIG. 10(B)), as shown in FIG. 10(C). Furthermore, as indicated by the dashed line in the figure, the fold LP is also stored and sealed inside the tape cutter 100 by the closing action of the shutter 30. In other words, in the tape cutter 100, the shutter 30 slides along the cylindrical side surface of the storage section 10, and when the cutter mechanism 20 is closed, it covers the mounting portion PS of the cutter mechanism 20, etc., together with the cutting blade BL, from the outside along the cylindrical side surface of the storage section 10, forming the fold LP while sealing the tape end TG.

[0053] Next, to reuse the tape TA stored as described above, as shown in FIG. 10(D), the shutter 30 is opened, i.e., slid in the direction of arrow A3 (typically, the user places their thumb on the pressing portion PP of the shutter 30 and pulls it upward), causing the cutter mechanism 20 to fall in the direction of arrow A4 under its own weight and open. At this time, a fold LP is formed at the tip of the tape end TG due to the series of operations described above. Therefore, as shown in FIG. 10(E), by pulling out the tape TA in the direction of arrow A5 while holding the fold LP, the tape TA can be cut off as shown in FIG. 10(F) without touching the adhesive surface AS of the tape TA. After the tape TA has been cut off, the state returns to that shown in FIG. 10(A), allowing the above-described operations to be repeated.

[0054] The formation of the fold LP in the above series of operations will be described in more detail below with reference to FIGS. 11(A) to 11(D). FIGS. 11(A) to 11(D) correspond to FIGS. 10(A) to 10(D). First, in the state shown in FIG. 11(A), the portion of the tape end TG from the first support portion SU1 on the cutter mechanism 20 side to the second support portion SU2 on the storage section side is supported by the first and second support portions SU1 and SU2. Here, this portion is referred to as the tape end TG1. Furthermore, the tape end TG1 is supported from the adhesive surface AS side by the protrusion TP of the movable portion MV. In other words, the protrusion TP supports the tape end TG1 (TG) from the adhesive surface AS side between the first support portion SU1 and the second support portion SU2. Due to the presence of the protrusion TP, when the cutter mechanism 20 is closed, the tape end TG1 bends outward (not inward) to assume a cylindrical shape with the adhesive surface AS facing inward, as shown in FIG. 11(B). As shown in the figure, when the cutter mechanism 20 is closed, it abuts against the stopper plate SB, positioning it within the tape storage section 10 and bringing the first support portion SU1 and the second support portion SU2 into close proximity. The protrusion TP is stored in the groove DT. When the shutter 30 is subsequently closed after the cutter mechanism 20 is closed, as shown in FIG. 11(C), the cylindrical tape end TG1 is pinched and crushed between the inner surface of the sealing portion CO of the shutter 30 and the outer surface of the cutter mechanism 20, causing the adhesive surface AS of the tape end TG1 to adhere and form the folded portion LP. The formed folded portion LP is then stored in a sealed state within the tape cutter 100 by the sealing portion CO of the shutter 30 during the closing operation, as described above. In the above case, the folded portion LP is stored pressed in the direction in which the tape TA is pulled out (the pulling direction), making it easy to remove for next use.

[0055] 11(C), when the shutter 30 is opened to use the tape cutter 100 again, the tape TA is exposed and ready to be cut, with a new tape end TG (referred to as tape end TG2) having a fold LP at its leading end facing the pulling direction (the direction of arrow A5) as shown in FIG. 11(D). After cutting, the state returns to that of FIG. 11(A).

[0056] As described above, the tape cutter 100 of this embodiment includes a storage section 10 that stores the tape TA, a cutter mechanism 20 that has a cutting blade BL that cuts the tape TA to form a tape end TG and a movable section MV that opens and closes while supporting the cutting blade BL, and a sliding shutter 30 that forms a fold LP at the tape end TG while sealing the cutting blade BL when the cutter mechanism 20 is closed. In the tape cutter 100 described above, the movable section MV that supports the cutting blade BL in the cutter mechanism 20 opens and closes, and the sliding shutter 30 forms a fold LP at the tape end TG while sealing the cutting blade BL when the cutter mechanism 20 is closed. In other words, the fold LP is formed at the tape end TG when the cutter mechanism 20 is closed. This makes it easier to remove the tape TA the next time it is cut, improving convenience. Furthermore, by forming the fold LP without directly touching the tape TA and closing the fold LP together with the cutting blade BL with the shutter 30, consideration is given to hygiene and safety.

[0057] 〔others〕 The present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit and scope of the present invention.

[0058] First, the shape of the tape cutter 100 described above is just one example, and is not limited to the above shape and can take various forms as long as a series of operations such as cutting out the tape TA and forming the fold LP are ensured.

[0059] In the above example, the protrusions TP support the tape end TG of the tape TA, but the protrusions TP do not need to maintain contact with the tape TA as long as they can prevent the tape TA from bending in an unintended direction. Furthermore, if the configuration of each part and the characteristics of the tape TA prevent the tape TA from bending in an unintended direction, the protrusions TP may be omitted.

[0060] In addition, in the above example, the tape TA is assumed to be a surgical tape, and is described as having a storage width WD corresponding to the tape width of the surgical tape, but the type of tape TA and the storage width WD can also be changed in various ways depending on the application.
