Detailed Description
An embodiment of the present invention will be described below with reference to fig. 1 to 15. Fig. 1 to 6 show a state (L) in which the movable body 2 with the cutter B is housed. Fig. 7 to 12 and 14 show that the movable body 2 with the cutter B can take a cutting posture (K). Fig. 13 is a perspective view for explaining an expanded state of the structure of the cutter body D, and fig. 15 shows an example of a state in which the movable body 2 with the cutter B is between the housed posture (L) and the cutting-enabling posture (K).
The tape cutter B of the present embodiment includes a movable body 2 provided with a blade P capable of taking a housing posture (L) and a cutting posture (K). The tape cutter B is configured to be capable of accommodating a blade P capable of cutting the adhesive tape T in the hollow portion C of the wound adhesive tape body a around which the adhesive tape T is wound in the accommodated posture (L).
The wound adhesive tape a is a coreless wound adhesive tape without a winding core. The adhesive tape T constituting the wound adhesive tape body a is, for example, masking tape (english). The wound adhesive tape body a is formed by winding and stacking an adhesive tape T having a predetermined length so as to surround a hollow portion C in a state where the hollow portion C in which the adhesive tape T is not present is provided in the central portion. The coreless wound adhesive tape body a has a substantially circular ring shape in side view. The width dimension of the wound adhesive tape body a is set to be substantially the same as the width dimension of the outer ring member E in the tape cutter B (for example, 15 mm).
The winding adhesive tape a is subjected to so-called tape-restraining (adhesion) treatment (japanese tape-backing treatment) on the inner peripheral surface n facing the hollow portion C. The "blocking-inhibiting treatment" is a known treatment for preventing the adhesive agent, not shown, applied to the adhesive tape T from exerting its adhesive force, and is performed, for example, by attaching a tape for preventing the adhesive agent from being exposed or by performing printing capable of forming a non-adhesive portion.
The tape cutter B includes: a cutter body D having a blade P; and an outer ring member E supported rotatably relative to the cutter body D and having an outer peripheral portion G engageable with an inner peripheral surface n of the winding adhesive tape body a.
The cutter body D includes: a base body 1, wherein the base body 1 is arranged in the hollow part C; and a movable body 2, wherein the movable body 2 is provided with a blade P and is configured to be movable relative to the base body 1, that is, configured to be capable of being moved out and in relation to the base body 1, and to be capable of moving the blade P to the vicinity of the outer peripheral surface of the wound adhesive tape body a in a cutting posture (K). For example, as shown in fig. 5, the cutter body D is configured so that the entire cutter body D can be accommodated in the hollow portion es of the outer ring member E in the accommodated posture (L). The cutter body D is substantially circular in side view in the housed posture (L).
The cutter body D is provided with a communication hole F into which a user's finger can be inserted when the movable body 2 is moved or when the cutter body D is rotated relative to the outer ring member E. A groove I that engages with a positioning male rail E1 provided in the inner peripheral portion of the outer ring member E is formed in the outer peripheral portion H of the base 1. The groove section I has a guide bottom surface I3 capable of engaging with the protruding tip end surface of the male rail section e1, and a pair of guide side surfaces, i.e., a first guide side surface I1 and a second guide side surface I2 capable of engaging with both outer side surfaces of the male rail section e1. The base 1 has a housing space sp in which the movable body 2 can be housed.
The base body 1 is always disposed in the hollow portion es, which is a space surrounded by the outer ring member E as a whole. As shown in fig. 13, the base 1 includes a first base constituent portion J1 and a second base constituent portion J2 connected to each other via a belt-like or plate-like connecting member J3. Further, the inner surface side of the first base body constituting portion J1 pivotally connected to the connecting member J3 is abutted against the inner surface side of the second base body constituting portion J2 pivotally connected to the connecting member J3, whereby the base body 1 is formed in an integral block shape as shown in fig. 6, for example.
The first base body constituent section J1 includes: a left outer wall portion 11 having a left outer side surface 11s as one side outer side surface and having a left communication hole constituting portion 11r which is one side of a communication hole F which can be formed in a left-right direction in cooperation with the second base constituting portion J2; and a left peripheral wall portion 13 which is one of the outer peripheral portions H engaged with the outer ring member E and can be formed in cooperation with the second base constituent portion J2.
The left peripheral wall portion 13 includes, in part, a first guide side surface i1 capable of guiding one side surface of the male rail portion e1, a second guide side surface i2 capable of guiding the other side surface of the male rail portion e1, and a guide bottom surface i3 located between the first guide side surface i1 and the second guide side surface i2.
As shown in fig. 6, the first guide side surface i1 is formed on a drop-preventing protrusion 13b of an elastic claw 13a as an elastic engagement body provided on the left peripheral wall portion 13. The elastic claws 13a are pressed by the projecting rail portions E1 provided on the inner peripheral surface of the outer ring member E so as to be elastically deformable temporarily when the cutter body D is attached to the outer ring member E. In other words, the cutter body D attached to the outer ring member E is not detached from the outer ring member E by the elastic claws 13a provided to the cutter body D.
The second base body constituent section J2 includes: a right outer wall portion 12 having a right outer side surface 12s as the outer side surface on the other side and having a right communication hole constituting portion 12r on the other side, which is the other side capable of forming a communication hole F penetrating in the left-right direction in cooperation with the first base constituting portion J1; and a right peripheral wall portion 14 which is the other of the outer peripheral portions H engaged with the outer ring member E and can be formed in cooperation with the first base body constituting portion J1.
The movable body 2 is connected to the right outer wall portion 12 via a first hinge m1 as a hinge. That is, a connection portion to the movable body 2 is provided on the inner surface of the right outer wall portion 12.
The right peripheral wall portion 14 includes a second guide side surface i2 capable of guiding the other side surface of the male rail portion e1, and a guide bottom surface i3 located between the first guide side surface i1 and the second guide side surface i2.
As shown in fig. 1 to 6, the movable body 2 can take a storage posture (L) in which it is stored in a storage space sp formed in the base body 1, and a cutting posture (K) in which the blade P is positioned on the outer surface side of the wound adhesive tape body a as shown in fig. 7 to 12 and 14. The movable body (2) is provided with: an intermediate member 21, the intermediate member 21 being coupled to the base 1 via a first hinge portion m 1; and a cutter member 22, the cutter member 22 being coupled to the intermediate member 21 via a second hinge m2 and having a blade P.
The first hinge portion m1 and the second hinge portion m2 are members called so-called resin hinges formed of a thin-walled synthetic resin that can be flexibly deformed. The movable body 2 can move the intermediate member 21 and the cutter member 22 between the cutting-enabling posture (K) and the storing posture (L) by the first hinge portion m1 and the second hinge portion m 2. In this embodiment, since the intermediate member 21 is formed in a substantially rectangular plate shape and the first hinge portion m1 and the second hinge portion m2 are linearly provided at the base end portion and the tip end portion, respectively, the blade P can be moved substantially parallel to the outer surface of the wound adhesive tape body a. For example, as shown in < a > < B > of fig. 14, the tape cutter B can position the blade P substantially parallel to the outer peripheral surface of the wound adhesive tape body a, regardless of the remaining amount of the adhesive tape T in the wound adhesive tape body a.
The intermediate member 21 has a plate shape, the base end portion is connected to the second base constituting portion J2 of the base 1 via the first hinge portion m1, and the tip end portion is connected to the cutter member 22 via the second hinge portion m 2.
When the movable body 2 assumes the storage posture (L), the intermediate member 21 assumes a posture along the inner surface of the right outer wall portion 12, and is entirely located in the storage space sp. On the other hand, when the movable body 2 is in the cutting-off posture (K), the distal end portion of the intermediate member 21 is positioned outside the accommodation space sp, and the intermediate member 21 assumes a posture of standing up with respect to the inner surface of the right outer wall portion 12.
The cutter member 22 includes a rising wall 221 having a base end portion connected to the second hinge portion m2, and a main wall 222 provided with a blade P and extending from a tip end of the rising wall 221 in a direction intersecting the rising wall 221, that is, in a direction substantially orthogonal to the direction.
The rising wall 221 has a plate shape. When the movable body 2 is in the storage posture (L), the standing wall 221 stands up with respect to the inner surface of the right outer wall portion 12 and is entirely located in the storage space sp, and when the movable body 2 is in the cutting-possible posture (K), the standing wall 221 can abut against the winding adhesive tape body a by taking a posture along the left outer side portion, which is one side of the winding adhesive tape body a, so that the cutter member 22 can be positioned.
The main wall 222 has a plate shape. When the movable body 2 takes the housing posture (L), the entire main wall 222 is positioned in the housing space sp and the outer surface 222s of the main wall 222 can be positioned substantially coplanar with the left outer wall portion 11 of the base 1.
On the other hand, when the movable body 2 is in the cutting-possible posture (K), the standing wall 221 can be brought into contact with the wound adhesive tape body a by taking a posture along the left outer side portion of the wound adhesive tape body a, so that the cutter member 22 can be positioned at a position suitable for cutting the adhesive tape T.
The main wall 222 includes: a blade P provided at the tip portion; a notch portion R provided at a rear end portion and curved so as to form a part of the communication hole F; an engagement protrusion Q protruding rearward at a rear end portion and engageable with an engagement recess V provided in the base 1 when in the storage posture; and a protrusion U for holding the posture, wherein the protrusion U for holding the posture is protruded to be positioned near the outer side part of the other side, namely the right side of the winding adhesive tape body A when the posture (K) can be cut.
The outer ring member E is a ring-shaped member in a side view in a form capable of being fitted in the wound adhesive tape body a. The outer ring member E is engaged with the outer peripheral portion H of the base 1 and is supported so as to be rotatable relative to the base 1.
The width dimension of the outer ring member E is set to be substantially the same as (e.g., 15 mm) or larger than the width dimension of the cutter body D when the movable body 2 takes the housing posture (L).
The outer peripheral portion G of the outer ring member E can engage with the inner peripheral surface n of the wound adhesive tape body a. An insertion promoting means S for promoting insertion of the wound adhesive tape body a into the hollow portion C is provided on the outer peripheral portion G of the outer ring member E. The insertion promoting means S in this embodiment is provided with a rib r formed on the outer peripheral portion G of the outer ring member E, and the distal end portion st engages with the inner peripheral surface n facing the hollow portion C.
A positioning male rail portion E1 that engages with a groove portion I provided in an outer peripheral portion H of the cutter body D is provided continuously in the circumferential direction at a left-right direction central portion of an inner peripheral portion of the outer ring member E.
Hereinafter, the operation of the tape cutter B according to the present embodiment will be schematically described.
First, the tape cutter B is fitted into the hollow portion C of the wound adhesive tape body a having a size corresponding to the tape cutter B. When the tape cutter B is inserted into the hollow portion C of the wound adhesive tape body a, the tip portion st of the rib r provided so as to protrude from the outer ring member E is pressed against the inner peripheral surface n of the wound adhesive tape body a, and the outer ring member E and the wound adhesive tape body a are integrally rotatably coupled.
Next, a finger is inserted into the communication hole F of the cutter body D, and the cutter member 22 is pulled out from the housing space sp of the base 1 to the outside, that is, to the cutting posture (K) side, by being brought into contact with the notch R of the cutter member 22 in the movable body 2 in the housing posture (L).
When the movable body 2 is pulled out, first, the engagement between the engagement convex portion Q provided on the main wall 222 of the cutter member 22 and the engagement concave portion V provided on the base 1 is released, and the movable body 2 is movable relative to the base 1.
Further, since the intermediate member 21 is connected to the base 1 via the first hinge portion m1, the cutter member 22 gradually rises from the left outer wall portion 11 as it moves outward. The cutter member 22 connected to the intermediate member 21 via the second hinge portion m2 gradually moves away from the base body 1 by a pulling operation by a user, and moves toward the outer surface side of the wound adhesive tape body a, which is a predetermined position where the adhesive tape T can be cut.
When the movable body 2 is moved from the storage posture (L) to the cutting-enabling posture (K), the rising wall 221 of the cutter member 22 is located on the left side surface side of the wound adhesive tape body a, and the main wall 222 of the cutter member 22 is located on the outer peripheral surface side of the wound adhesive tape body a. The posture-holding protrusion U protruding downward from the main wall 222 is located on the right side surface of the wound adhesive tape body a, and can engage with the right side surface portion of the wound adhesive tape body a.
In other words, in the cutting-enabling posture (K), the cutter member 22 is configured so that the standing wall 221 and the posture-holding protrusion U cooperate to be positioned with respect to the wound adhesive tape body a, and the blade P provided on the main wall 222 can take an appropriate posture for easily cutting the adhesive tape T.
Then, the tip end portion of the adhesive tape a is found while rotating the wound adhesive tape body a held by the outer ring member E with respect to the cutter body D, and the adhesive tape T of a predetermined size desired by the user is pulled out from the wound adhesive tape body a.
Then, the pulled adhesive tape T is pulled toward the blade P of the cutter member 22 in the cutting-enabling posture (K), and the adhesive tape T is cut by the blade P.
When the process for cutting the adhesive tape T is completed, the movable body 2 is changed from the cutting-enabling posture (K) to the storing posture (L) through a step opposite to the above-described step. Finally, the engagement convex portion Q formed at the rear end portion of the cutter member 22 is engaged with the engagement concave portion V provided in the base 1, whereby the movable body 2 is appropriately held in the accommodated posture (L).
As described above, the tape cutter B of the present embodiment is disposed in the hollow portion C of the wound adhesive tape body a around which the adhesive tape T is wound, and includes: a cutter body D having a blade P capable of cutting the adhesive tape T; and an outer ring member E supported rotatably relative to the cutter body D and having an outer peripheral portion G engageable with an inner peripheral surface n of the winding adhesive tape body a.
Accordingly, the tape cutter B having a structure in which the wound adhesive tape body a can smoothly rotate with respect to the cutter body D having the blade P capable of cutting the adhesive tape T can be provided.
The cutter includes a male rail portion E1 provided on an inner peripheral portion of an outer ring member E for positioning, and a groove portion I provided on an outer peripheral portion H of a cutter body D and engaged with the male rail portion E1.
Therefore, in a state where the outer ring member E is properly positioned with respect to the cutter body D, the outer ring member E can relatively rotate with respect to the cutter body D.
The groove portion I includes a first guide side surface I1 as a guide surface capable of guiding one side surface of the male rail portion E1, and the cutter body D includes an elastic claw 13a capable of being temporarily elastically deformed by being pressed by the male rail portion E1 when mounted on the outer ring member E, and the first guide side surface I1 is provided on the elastic claw 13 a.
Therefore, the outer ring member E can be appropriately attached to the cutter body D, and is not easily detached from the cutter body D after the attachment.
An insertion promoting means S for promoting insertion of the wound adhesive tape a into the hollow portion C is provided on the outer peripheral portion G of the outer ring member E, and the insertion promoting means S is provided with a rib r formed on the outer peripheral portion G of the outer ring member E and engaging the tip portion st with the inner peripheral surface n of the wound adhesive tape a facing the hollow portion C.
Accordingly, the outer ring member E can be smoothly inserted into the hollow portion C of the winding adhesive tape body a, and the outer ring member E after the insertion can be appropriately engaged with the inner peripheral surface n of the winding adhesive tape body a, so that the outer ring member E and the winding adhesive tape body a can be appropriately integrally rotated.
The cutter body D is provided with a communication hole F into which a finger of a user is inserted. Therefore, the user can easily rotate the cutter body D with respect to the outer ring member E and the wound adhesive tape body a.
The tape cutter B of the present embodiment is configured to be capable of accommodating the blade P capable of cutting the adhesive tape T in the hollow portion C of the wound adhesive tape body a around which the adhesive tape T is wound. The tape cutter B includes: a base body 1, wherein the base body 1 is arranged in the hollow part C; and a movable body 2, wherein the movable body 2 is provided with a blade P, and is configured to be movable relative to the base body 1 and to be movable to the vicinity of the outer surface of the wound adhesive tape body a.
Therefore, in the case of the tape cutter according to the present embodiment, the tape cutter B can be provided which has a compact posture in which the tape cutter B does not overlap with the outer surface and the outer peripheral surface of the wound adhesive tape body a when not in use, does not impair the external appearance of the wound adhesive tape body a, and is easy to use in a state of being held by hand when in use.
The movable body 2 can move the blade P substantially parallel to the outer peripheral surface of the wound adhesive tape body a. Therefore, the blade P can take an appropriate posture that can cut the adhesive tape T regardless of the amount of the remaining adhesive tape T in the wound adhesive tape body a.
The movable body 2 includes: an intermediate member 21, the intermediate member 21 being coupled to the base 1 via a first hinge portion m 1; and a cutter member 22, the cutter member 22 being coupled to the intermediate member 21 via a second hinge m2 and having a blade P.
Therefore, the intermediate member 21 and the cutter member 22 can be operated in a stable posture by the configuration in which the first and second hinge portions are provided.
The cutter member 22 includes a rising wall 221 having a base end connected to the second hinge portion m2, and a main wall 222 provided with a blade P and extending from a tip end of the rising wall 221 in a direction intersecting the rising wall 221. Accordingly, the cutter member 22 has the rising wall 221 and the main wall 222, and thus can be properly positioned with respect to the wound adhesive tape body a for cutting the adhesive tape T.
The movable body 2 can take a storage posture (L) stored in a storage space sp formed in the base body 1 and a cutting posture (K) in which the blade P is positioned on the outer surface side of the wound adhesive tape body a.
Therefore, the cutter body D can be provided in a compact posture in the housing posture (L) and in an appropriate posture in which the adhesive tape T can be cut in the cutting-enabling posture (K).
The cutter body D is composed of the base body 1 and the movable body 2, and includes a communication hole F into which a user's finger is inserted when the movable body 2 is moved. Therefore, although the cutter body D takes a compact posture, the movable body 2 can be easily pulled out to the outside by inserting a finger into the communication hole F. Further, the operation of rotating the cutter body D with respect to the outer ring member E can be easily performed by the communication hole F.
An outer ring member E engaged with an outer peripheral portion H of the base 1 and supported so as to be rotatable relative to the base 1 is provided. The outer peripheral portion G of the outer ring member E can engage with the inner peripheral surface n of the winding adhesive tape body a. Therefore, the wound adhesive tape body a can be rotated with respect to the cutter body D, and the adhesive tape T can be cut appropriately at a desired position by the blade P of the movable body 2.
When the blade P is in the storage posture (L), the tape cutter B can expose the entire area of the outer side portion of the wound adhesive tape body a to the outside. Therefore, the user can easily visually confirm the appearance of the wound adhesive tape body a attached to the tape cutter B.
For example, if the adhesive tape body T around which the adhesive tape body a is wound is a masking tape on the outer surface of which various patterns or the like are easily provided for printing, the tape cutter B of the present embodiment is suitably applied. That is, since the tape cutter B is easy to maintain the printed display of the masking tape in a state that can be visually confirmed from the outside, it is possible to provide an appropriate appearance based on the printed display of the masking tape, and to perform an operation that can cut the masking tape when necessary.
Furthermore, the present invention is not limited to the embodiments described in detail above.
A tape cutter B according to another embodiment will be described with reference to fig. 16 to 19.
The band cutter B of the present embodiment is different from the above-described embodiment mainly in the configuration of the cutter member 22 in the movable body 2 and the width of the outer ring member E with respect to the cutter body D.
The outer surface 222s of the main wall 222 of the cutter member 22 is provided with a projection W for easily catching a finger of a user so as to follow the curved notch portion R. The cutter member 22 includes an extending wall U for holding the posture protruding from an end edge of the main wall 222 on the opposite side from the rising wall 221 in a direction substantially orthogonal to the main wall 222, and an engaging protrusion Q capable of engaging with the base 1 in the accommodated posture (L) is provided on an outer surface thereof. That is, the engagement convex portion Q protruding from the extension wall U can be engaged with the engagement concave portion V provided in the base 1 when the housing posture (L) is assumed.
The outer ring member E is set smaller than the width dimension of the cutter body D.
Even in the other embodiments described above, the desired object can be achieved.
The winding adhesive tape body is not limited to the masking tape.
The wound adhesive tape may not be a coreless wound adhesive tape, but may have a winding core.
A groove portion may be provided in an inner peripheral portion of the outer ring member, and a projection or a projecting rail portion engaged with the groove portion may be provided in the cutter body.
The sizes of the cutter body and the outer ring member constituting the tape cutter can be appropriately set according to the size of the wound adhesive tape body a to be attached.
The movable body may be provided with two or more hinge portions. Further, a plurality of plate-like or block-like intermediate members may be provided on the movable body, the plate-like or block-like intermediate members having hinge portions at both end portions.
The movable body may be provided with a flexible string-like, band-like or wire-like intermediate member connecting the cutter member provided with the blade and the base.
The movable body having the blade is not limited to the movable body movable between the housing posture and the cutting posture on the left side of the base body, and may be the movable body movable between the housing posture and the cutting posture on the right side of the base body.
The outer ring member is not necessarily limited to a member having a circular shape in side view, and may have a different shape from a circular shape.
The width of the outer ring member may be set to be substantially the same as the width of the cutter body, or may be set to be smaller than the width of the cutter body.
The specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
