Description

The present invention relates to a tape core used in a tape dispenser.

Conventionally, tape cores around which tape is wound and which are attached to a tape dispenser for use are known (see, for example, Patent Document 1).

Recently, tapes with a wide variety of patterns, designs, colors, etc., such as masking tape, have appeared. In order to be able to use multiple variations of tape quickly, it is necessary to prepare multiple tape cores and wind each tape individually around the tape cores.

However, doing this raises concerns that the number of tape cores holding the tape will increase too much, and they will tend to become scattered, making management extremely cumbersome. In particular, if the tape cores are relatively small, there is a risk that they will get lost while being carried around.

One embodiment of the present invention will be described below with reference to Figures 1 to 17.

This embodiment is applied to a tape dispenser D that can hold masking tape, which is tape T.

The tape dispenser D comprises a tape dispenser body A, a refill B which holds a tape T and is supported rotatably relative to the tape dispenser body A, and a tape extrusion section C which is supported so as to be movable relative to the tape dispenser body A, i.e., to move linearly forward and backward. The tape extrusion section C constitutes a tip separation means which separates the tip st of the tape T from the cutting section 5.

The tape dispenser D in this embodiment is relatively small, with dimensions in the front-to-rear direction set at approximately 3 cm.

The components of the tape dispenser D are described in detail below.

<<Tape dispenser body A>>
The tape dispenser body A includes left and right side walls 1 and 2, a refill support shaft 3 serving as a tape body support section disposed between the left and right side walls 1 and 2, a holding section 4 disposed between the left and right side walls 1 and 2 to temporarily adhere and hold the tape T pulled out from the tape body R, and a cutting section 5 disposed between the left and right side walls 1 and 2 and having a blade 51 for cutting the tape T pulled out from the tape body R.

<Left and right side walls 1, 2>
The left and right side walls 1, 2 form a pair and have substantially the same shape. Each of the left and right side walls 1, 2 has a substantially horizontal egg shape whose vertical dimension gradually becomes shorter toward the front.

The left and right side walls 1 and 2 each have a rear partial arc edge e1 that is partially arc-shaped in side view, an upper straight edge e2 that continues from the rear partial arc edge e1 and extends forward to form the upper edge, a lower straight edge e3 that continues from the rear partial arc edge e1 and extends forward to form the lower edge, and a front partial arc edge e4 that is partially arc-shaped in side view and connects the front end of the upper straight edge e2 and the front end of the lower straight edge e3. The left and right side walls 1 and 2 each have a shape in which the upper straight edge e2 and the lower straight edge e3 gradually approach each other from the rear to the front.

As shown in FIG. 5, the left side wall 1 has a plurality of recesses 11 on its outer surface that serve as engaging portions that form a connecting portion S that can be connected to the tape core M. In this embodiment, the recesses 11 are provided in six locations. The six recesses 11 are provided at positions that are approximately equidistant from the axis of the refill support shaft 3 so as to surround the axis of the refill support shaft 3. Of the six recesses 11, adjacent recesses 11 are arranged at equal intervals from each other.

The rear edge of the left side wall 1 has multiple anti-slip projections 12 (two on top and two on the top) that the user can catch on.

On the inner surface of the left side wall 1, from rear to front, the refill support shaft 3, the holding portion 4, and the cutting portion 5 are each provided to protrude toward the right side wall 2. Around the refill support shaft 3 on the inner surface of the left side wall 1, a donut-shaped recessed portion 13 is formed in which the left side plate m3 of the tape core M is disposed.

The recess 13 is designed to accommodate the protrusion 21 protruding from the right side plate m2 when the tape core M is installed in the tape dispenser body A in a left-right inverted manner.

As shown in FIG. 4, the right side wall 2 has a plurality of protrusions 21 on the outer surface of the rear portion, which serve as engaging portions that form a connecting portion S that can be connected to the tape core M. In this embodiment, the protrusions 21 are provided in two locations. The two protrusions 21 are provided at positions that are approximately equidistant from the axis of the refill support shaft 3. The two protrusions 21 are disposed symmetrically around the axis of the refill support shaft 3.

On the inner surface of the right side wall 2, there are provided, from rear to front, a cylindrical support shaft support member 22 that is inserted into the hollow portion 31 of the refill support shaft 3 erected on the left side wall 1, a plate-shaped holding portion support member 23 that is inserted into the hollow portion 41 of the holding portion 4 erected on the left side wall 1, and a fitting recess (not shown) into which the fitting protrusion 52 at the tip of the cutting portion 5 erected on the left side wall 1 can fit.

When the refill B is to be attached to the tape dispenser body A, first, the left side wall 1 and the right side wall 2 are separated, and the refill support shaft 3 provided on the left side wall 1 is inserted into the shaft hole m11 of the refill B. Next, the left and right side walls 1 and 2 are butted against each other, and the support shaft support member 22, the holding portion support member 23, and the fitting recess (not shown) provided on the right side wall 2 are engaged with the hollow portion 31 of the refill support shaft 3, the hollow portion 41 of the holding portion 4, and the fitting protrusion 52 provided on the left side wall 1. The refill B is held in a usable state for the tape dispenser body A. On the other hand, if the left and right side walls 1 and 2 are separated from each other, the refill B can be removed or replaced with another refill B.

<Refill support shaft 3>
The refill support shaft 3 extends in the left-right direction. The refill support shaft 3 is cylindrical, and the support shaft support member 22 erected on the right side wall 2 is inserted into the internal hollow portion 31.

The refill support shaft 3 is capable of rotatably supporting the refill B, which holds the tape body R formed by winding the tape T into a roll. In other words, the refill support shaft 3 is inserted into the shaft hole m11 that penetrates the cylindrical portion m1 of the refill B in the left-right direction.

<Holding portion 4>
The holding portion 4 extends in the left-right direction and is disposed in front of the refill support shaft 3. The holding portion 4 has a rectangular cylindrical shape, and the holding portion support member 23 erected on the right side wall 2 is inserted into the internal hollow portion 41.

The holding section 4 has a tape adhesive section 42 on its upper end surface to which a portion of the tape T pulled out from the tape body R can be temporarily adhered. The tape adhesive section 42 is configured as an inclined surface that gradually descends from the rear side to the front side in a side view. The tip of the blade 51 in the cutting section 5 is positioned on an imaginary extension line of the tape adhesive section 42.

The front surface of the holding part 4 is an upright surface. The back surface of the holding part 4 is a curved surface with the vertical middle part recessed further forward than the upper and lower ends so as not to interfere with the refill B supported by the refill support shaft 3. The bottom surface of the holding part 4 is an inclined surface that gradually descends from the front to the rear.

<Cutting section 5>
The cutting portion 5 extends in the left-right direction and has at its upper end a blade 51 capable of cutting the tape T pulled out from the tape body R. The cutting portion 5 is disposed in front of the holding portion 4. The cutting portion 5 has an upright plate shape. The extending end of the cutting portion 5 extending from the left side wall 1 is provided with an engagement protrusion 52 which fits into an engagement recess (not shown) formed in the right side wall 2.

Upper and lower engaging recesses 53, 54 are formed in two mountain-shaped recesses at upper and lower positions on the back surface of the cutting portion 5. The upper and lower engaging recesses 53, 54 cooperate with an elastic engaging portion 62 of the tape pushing portion C to form a resistance portion U described later.
<<Refill B>>
The refill B is composed of a tape core M and a tape body R in which a tape T is wound around the tape core M in a roll shape.

The tape core M holds the tape body R that is formed into a roll by winding the tape T. The tape core M is attached to the tape dispenser body A for use.

The tape core M has a cylindrical section m1 located in the center and extending in the left-right direction, a pair of side plates m3, m2 located on both the left and right ends of the cylindrical section m1, and a connecting section S located on the left and right side plates m3, m2 that can be connected to other tape cores M of the same shape.

As will be described in more detail later, the tape core M of this embodiment is configured to be connectable to other tape cores M of the same shape via a connecting portion S.

<Cylindrical portion m1>
The cylindrical portion m1 has a cylindrical shape penetrating in the left-right direction. That is, the cylindrical portion m1 has an axial hole m11 into which the refill support shaft 3 is inserted. The tape core M is rotatably supported with respect to the tape dispenser body A by inserting the refill support shaft 3 provided in the tape dispenser body A into the axial hole m11 of the cylindrical portion m1.

<Left and right side panels m3, m2>
The left and right side plates m3, m2 each have a generally donut shape in side view, and extend like a brim from the edge of the cylindrical portion m1.

<Connection part S>
The connecting portion S provided on the tape core M is for connecting to another tape core M having the same structure. In this embodiment, the connecting portion S is provided on each of the left and right side plates m3, m2 of the tape core M, so that other tape cores M having the same structure can be connected to the left and right of the tape core M.

In other words, if multiple refills B are prepared, each of which has tape T wound around a tape core M, the multiple refills B can be connected in a daisy-chain fashion in the horizontal direction by the connecting parts S.

The connecting portion S is provided on each of the left and right side plates m3 and m2. More specifically, the connecting portion S is composed of a protrusion r1 provided on the right side plate m2, which is one of the side plates, and an engagement hole r2, which is provided on the left side plate m3, which is the other side plate, and which serves as an engagement portion with which the protrusion r1 can engage.

The protrusion r1 on the right side plate m2 of the tape core M fits into the engagement hole r2 on the left side plate m3 of another tape core M of the same structure, allowing the two tape cores M, M to be connected to each other.

The engagement hole r2 on the left side plate m3 of the tape core M fits over the protrusion r1 on the right side plate m2 of another tape core M of the same structure, allowing the two tape cores M, M to be connected to each other.

First, we will explain the protrusion r1 on the right side panel m2.

The protrusion r1 is cylindrical. The protrusion r1 protrudes outward from the outer surface of the right side plate m2. The protrusions r1 are arranged in multiple locations, i.e., in two locations. The two protrusions r1 are provided at positions approximately equidistant from the axis of the cylindrical portion m1. The two protrusions r1 are arranged at positions approximately symmetrical with respect to the axis of the cylindrical portion m1.

Next, we will explain the engagement hole r2 provided in the left side plate m3.

The engagement hole r2 is a round hole sized to fit onto the cylindrical protrusion r1. The engagement hole r2 is a through hole penetrating in the left-right direction. There are multiple engagement holes r2, i.e., six. The six engagement holes r2 are provided at positions approximately equidistant from the axis of the cylindrical portion m1 so as to surround the axis of the cylindrical portion m1. The six engagement holes r2 are arranged at equal intervals from one another.

In this embodiment, the number of engagement holes r2 on the left side plate m3 is set to be greater than the number of protrusions r1 on the right side plate m2. Setting the protrusions r1 and engagement holes r2 of the tape core M in this way makes it easier to connect the protrusions r1 of the tape core M to the engagement holes r2 of the other tape core M.

In other words, the user can operate the two protrusions r1 so that they fit into any of the six engagement holes r2, allowing the tape core M to be connected to another tape core M by casually butting the protrusions r1 and the engagement holes r2 together (roughly butting them together).

In addition, by making the number of protrusions r1 less than the number of engagement holes r2, it is possible to reduce the number of protrusions r1, which are easily noticeable due to their shape and tend to detract from the design, thereby helping to ensure a favorable appearance for the entire tape core M.

Furthermore, since adjusting the mold to form the protrusions r1 requires a relatively large amount of labor, making the number of protrusions r1 smaller than the number of engagement holes r2 helps reduce the amount of labor required to adjust the mold.

In addition, as shown in Figures 12 to 14, the connecting portion S of the tape core M is configured to be connectable to the connecting portions S (concave portion 11 or convex portion 21) provided on the outer portion of the tape dispenser D, i.e., the left and right side walls 1 and 2 of the tape dispenser body A.

Furthermore, as shown in Figures 15 to 17, the connection portion S (protrusion r1) of the tape core M is configured to be connectable to the connection portion S (engagement hole k1) of the rotating plate K that is directly connected to the operating handle J provided on the tape rewinder E. The specific configuration of the tape rewinder E will be described in detail later.

<<Tape extrusion section C>>
The tape extrusion part C is supported so as to be movable forward and backward relative to the tape dispenser body A. The tape extrusion part C is configured to be movable relative to the tape dispenser body A by a user's operation so as to extrude the tape T in a direction intersecting the stretching direction of the tape T.

The tape extrusion section C includes an upper section 6 that extends in the vertical direction and has an extrusion head 61 formed at its upper end that abuts against the adhesive surface nm side of the tape T, and a lower section 7 that extends diagonally rearward and downward from the lower end of the upper section 6. The upper section 6 and lower section 7 form a dogleg shape in a side view of the tape extrusion section C.

<Upper part 6>
The upper portion 6 is generally in the form of a plate extending in the left-right and up-down directions. The upper portion 6 is provided with an extrusion head 61 at its upper end capable of contacting the tape T, and an elastic engagement portion 62 that is cantilevered on the right side of the vertical middle portion as viewed from the front so that its lower end is a free end, and has a locking protrusion 62a at its lower end, which can be locked with the upper and lower locking recesses 53, 54 of the cutting portion 5. The upper portion 6 is located in a gap sk that is formed between the cutting portion 5 and the holding portion 4 and extends in the vertical direction, and can be moved in the vertical direction while being guided by the gap sk.

The extrusion head 61 is formed with a movement restriction portion 61a that protrudes forward below the upper end. The movement restriction portion 61a engages with the upper portion of the cutting portion 5 when the tape extrusion portion C is located at the retracted position (Q), and is capable of restricting the tape extrusion portion C from moving downward below the retracted position (Q).

The elastic engagement portion 62 constitutes a resistance portion U that prevents the tape extrusion portion C from moving to the extrusion position (P) or the retracted position (Q) until a predetermined pressure is applied. In other words, the elastic engagement portion 62 selectively engages with either the upper engagement recess 53 or the lower engagement recess 54 provided in the cutting portion 5, and can moderately engage the tape extrusion portion C at the extrusion position (P) and the retracted position (Q).

More specifically, when the tape extrusion portion C is in the extrusion position (P), the locking protrusion 62a of the elastic engagement portion 62 elastically engages with the upper locking recess 53 in the cutting portion 5, thereby holding the tape extrusion portion C in the extrusion position (P). Also, when the tape extrusion portion C is in the retracted position (Q), the locking protrusion 62a of the elastic engagement portion 62 engages with the lower locking recess 54 in the cutting portion 5, thereby holding the tape extrusion portion C in the retracted position (Q).

<Lower part 7>
The lower portion 7 is in the form of a plate extending obliquely downward and rearward integrally with the lower end of the upper portion 6 .

The lower portion 7 of the tape extrusion portion C has a pressable portion 71 that is located below the holding portion 4 of the tape dispenser body A and can be pressed upward by the user. In other words, by pressing the pressable portion 71 of the tape extrusion portion C, which is in the retracted position (Q), upward with the user's fingers, the tape extrusion portion C can move to the extrusion position (P) against the resistance of the resistance portion U.

During this process, the tape extrusion section C pushes the tape T pulled out from the tape body R from below to above. Then, when the tape extrusion section C reaches the extrusion position (P), the tip st of the tape T moves away from the cutting section 5 to an extent that the user's fingertips can reach in, making it easier for the user to pick up the tip st of the tape T with their fingers.

The tape extrusion section C is configured to be movable between an extrusion position (P) located on the tape orbit kd between the tape body R and the cutting section 5, and a retracted position (Q) retracted from the tape orbit kd.

In this embodiment, the tape extrusion section C is provided between the cutting section 5 and the holding section 4. In other words, the tape extrusion section C is held so as to be movable up and down by the cooperation of the cutting section 5 and the holding section 4.

While moving from the retracted position (Q) to the extrusion position (P), the tape extrusion section C can abut against the lower surface of the tape T, i.e., the adhesive surface nm side, and extrude the tape T upward.

In this embodiment, the tape extrusion section C at the extrusion position (P) is configured to automatically move toward the retracted position (Q) as the user cuts the tape T. In other words, when the user holds the tip st of the tape T and pulls out a certain length of tape T outward, i.e., forward, and then lowers the tape T while applying tension to it so that it is cut by the blade 51, the tape extrusion section C is pressed down by the tape T and moves to the retracted position (Q).

A resistance portion U is provided between the tape extrusion portion C at the extrusion position (P) and the tape dispenser body A. Therefore, when the resistance portion U receives a predetermined downward pressure associated with the above-mentioned cutting operation by the user (operation to lower the tape T), the tape extrusion portion C can move in the direction of the retracted position (Q) against the resistance force of the resistance portion U.

<<Tape rewinder E>>
A tape rewinder E having a configuration in which the tape cores M constituting the refill B can be connected via a connecting portion S will be described.

As shown in Figures 15 to 17, the tape rewinder E is capable of rewinding the tape TL pulled out from a pre-made tape body L onto a tape core M. The tape rewinder E rotatably holds the pre-made tape body L in which the tape TL is wound into a roll. The tape rewinder E is also provided with an operating handle J that is rotated by the user. A rotating plate K that can rotate together with the operating handle J is provided at the base end of the operating handle J. The tape rewinder E is also capable of attaching the tape core M of the tape dispenser D to the rotating plate K.

That is, the tape rewinder E is capable of rewinding the tape TL pulled out from the prefabricated tape body L onto the tape core M connected to the rotary plate K by rotating the operating handle J. The tape rewinder E pulls out the tape TL from the prefabricated tape body L and then winds the tape TL again around the cylindrical portion m1 of the tape core M, thereby enabling a portion of the tape TL to be divided off from the prefabricated tape body L and placed on the tape core M side.

The tape rewinder E is equipped with a base body F that can take a holding position (a) in which the tape core M can be held so as not to come off and a removable position (b) in which the tape core M can be attached and detached to the rotating plate K, a tape body holding section G that can rotatably support a prefabricated tape body L on the base body F, an operating handle J that is rotatably supported on the base body F, a rotating plate K that is provided with a connecting section S that rotates integrally with the operating handle J and to which the tape core M can be connected, and a tape core M that is configured to be removable from the rotating plate K.

The rotating plate K has engagement holes k1 as connecting parts into which the two protrusions r1 can be fitted, at positions corresponding to the two connecting parts of the tape core M. With the base F in the removable position (b), the tape core M is attached to the rotating plate K via the connecting parts, and then the second base member f2 in the deployed position (d) is changed to the usage position (c), so that the base F in the holding position (a) can hold the tape core M so that it can rotate integrally with the operating handle J.

The base body F is equipped with a first base member f1 having one standing wall f11, a second base member f2 having the other standing wall f21 and configured to be capable of adopting a usage position (c) in which the other standing wall f21 is approximately parallel to the first base member f1, and an unfolded position (d) in which the other standing wall f21 is approximately parallel to a support surface such as a tabletop, and a locking mechanism N capable of locking the second member in the usage position (c).

As described above, the tape core M according to this embodiment is wound with tape T and is attached to a tape dispenser D for use. The tape core M can be connected to other tape cores M of the same shape via a connecting portion S. This makes it possible to provide a tape core M that is configured so that multiple tape cores M are less likely to become separated.

In other words, even if multiple tape cores M are prepared and each tape T with a wide variety of patterns, designs, colors, etc. is wound individually around the tape cores M, each tape core M can be connected together by the connecting parts S.

As a result, even if the number of tape cores M holding tape T increases, management is unlikely to become complicated. In other words, the user can quickly select the tape T he or she wants to use from among the multiple connected tape cores M, and insert it into the tape dispenser D for use.

In addition, even if the tape core M is relatively small as in this embodiment, the risk of it being lost while being carried around is effectively reduced.

In addition, by connecting multiple tape cores M, tapes T with a wide variety of patterns, designs, colors, etc. can be organized in an orderly manner. Therefore, as shown in the example of Figure 14, even when not in use, it can function as a decorative item that is visually appealing to the viewer and gives an aesthetic impression.

The tape core M has a pair of side plates m3 and m2 on the left and right, and a connecting portion S is provided on each of the side plates m3 and m2.

As a result, not only can another tape core M of the same shape be connected to the left side plate 3m of the tape core M, but also another tape core M of the same shape can be connected to the right side plate m2.

The connecting portion S has a protrusion r1 provided on the right side plate m2, which is one of the side plates, and an engagement hole r2, which is an engagement portion provided on the left side plate m3, which is the other side plate, with which the protrusion r1 can engage.

Therefore, by fitting the protrusion r1 of the tape core M into the engagement hole r2 of the other tape core M, or by fitting the engagement hole r2 of the tape core M into the protrusion r1 of the other tape core M, the two tape cores M can be suitably connected to each other.

The number of engagement holes r2, which are engagement parts, provided on the left side plate m3, which is the other side plate, is set to be greater than the number of protrusions r1 provided on the right side plate m2, which is one side plate.

This makes it relatively easy to connect the protrusion r1 of one tape core M to the engagement hole r2 of another tape core M.

In this embodiment, the user can operate the two protrusions r1 so that they fit into any of the six engagement holes r2. Therefore, the user can connect the tape core M to another tape core M by casually butting the protrusions r1 and the engagement holes r2 together (roughly butting them together).

In addition, by making the number of protrusions r1 less than the number of engagement holes r2, it is possible to reduce the number of protrusions r1, which are conspicuous due to their shape and may spoil the aesthetic appearance, thereby helping to ensure a favorable appearance for the entire tape core M.

Furthermore, in the process of manufacturing the tape core M, adjusting the die to form the protrusions r1 requires a relatively large number of steps, so making the number of protrusions r1 less than the number of engagement holes r2 helps reduce the number of steps required to adjust the die.

The connecting portion S is configured so that it can be connected to the outer surfaces of the left and right side walls 1 and 2, which are the outer parts of the tape dispenser D.

This allows a tape core M that is not built into the tape dispenser D to be connected to one or both of the left and right side walls 1 and 2. This allows the user to select a tape core M with the tape T he or she wants to use wound thereon from among the multiple tape cores M connected to the tape dispenser D, and quickly attach it to the tape dispenser D for use.

In addition, unused tape cores M can be connected to the tape dispenser D directly or indirectly via the tape cores M, which not only effectively prevents the tape cores M from scattering, but also effectively prevents the tape cores M from being lost.

The connection portion S of the tape core M is configured so that it can be connected to a rotating plate K that is directly connected to an operating handle J provided on the tape rewinder E. The tape rewinder E is capable of rewinding the tape LT pulled out from a prefabricated tape body L, in which the tape LT is wound in a roll, onto the tape core M connected to the rotating plate K by rotating the operating handle J.

Therefore, the tape core M can be stably attached to the tape rewinder E via the connecting portion S and used. In other words, the tape core M can be used to rewind the tape TL for the purpose of dividing the tape LT of the pre-fabricated tape body L. For example, if multiple tape cores M are prepared and each tape core M is sequentially attached to the rotating plate K and the tape rewinder E is operated, the tape TL that formed the pre-fabricated tape body L can be divided into multiple tape cores M. Since the tape core M is connected to the rotating plate K via the connecting portion S, the tape TL divided from the pre-fabricated tape body L can be appropriately wound around the tape core M.

The present invention is not limited to the embodiments described above.

Various types of tape can be used and are not limited to masking tape.

The tape dispenser in which the tape core is installed is not limited to the embodiment described above.

The specific form of the connecting portion is not limited to that configured by the convex portion and the engagement hole as described above. For example, the connecting portion may be capable of connecting the tape core to another tape core having the same shape by a magnet, or may be capable of connecting by a hook-and-loop fastener.

The left and right side panels do not necessarily have to be formed in a circular (donut) shape; they may be polygonal, elliptical, or asymmetrical.

The engaging portion with which the protrusion can engage may be a recess that is limited to an engaging hole.

In the above-described embodiment, the number of engaging portions provided on the other side plate is set to be greater than the number of protruding portions provided on one side plate, but this is not limited to the above. For example, the number of engaging portions and protruding portions may be set to be the same. Also, for example, the number of engaging portions provided on the other side plate may be set to be less than the number of protruding portions provided on one side plate.

The specific configuration of each part is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.
