Japanese Patent No. 4979037 Japanese Patent No. 5156895

However, since the tape dispenser of Patent Literature 1 forms the cutting blade and the second temporary retaining portion on the upper end surface of the swing plate, the tape is always adhered to the blade edge after being cut. Become. For this reason, the adhesive material of the tape sticks to the blade edge, and there is a disadvantage that the performance of the cutting blade is deteriorated.
In addition, since it is necessary to provide a predetermined interval between the first temporary holding part and the second temporary holding part before cutting, it swings against the force of the spring or magnet. The tape had to be pulled out with the plate displaced, and there was a problem in operability.

On the other hand, since the tape dispenser of Patent Document 2 has to temporarily fasten the drawn adhesive tape to the first temporary holding portion and simultaneously pull out the tape to temporarily fix the second temporary holding portion. It could not be pulled out smoothly.
Then, an object of this invention is to provide the tape dispenser which can form the knob | pick part for the next cutting operation by simple and smooth operation, without reducing the cutting performance of a cutting blade.

In order to solve the above problems, a tape dispenser of the present invention includes a base provided with a cutting blade for cutting an adhesive tape, a holder member attached to the base so as to be displaceable, and the holder member the saw including a pivotal sealed reel member, the upper end of the mounting portion provided on the tape pull-out direction front end of the holder member, provided with a first temporary engaging portion for temporarily fastening the pulled out tape A tape dispenser configured by pivoting a swinging member having a second temporary retaining portion at the upper end to the base, and rotatably connecting the swinging member and the mounting portion by a link bar, the second temporary fixing portion by pulling out the tape proximate the cutting blade, by cutting the tape at said cutting blade, said swinging member with the holder member is displaced in a direction away from said cutting blade, Above Temporary engaging portion of 2 is characterized in that is configured to substantially close contact with said first temporary engaging portion.
In this case, a plurality of concavities are provided at predetermined intervals on the edge of one end of the planar cutting blade to form a cutting edge, and an angle formed by the concavity and the edge formed by drawing the tape toward the cutting edge. A tape dispenser configured to cut a tape at a portion and cut the tape in a straight line while scoring at an edge portion, and a predetermined portion from a cut tape end portion at a flat portion leading to the cutting edge. A knob having a non-adhesive region where the long tapes are not in contact with each other may be formed .
Further, the tape dispenser is configured such that the holder member is rotatably attached to the base, and the holder member is rotated by pulling out the tape to cut the second temporary holding portion. Even if it is close to the blade and cuts the tape at the cutting blade, the holder member is rotated by its own weight to displace the sliding member in a direction away from the cutting blade. Good.

In the tape dispenser according to the present invention , the holder member for holding the adhesive tape is detachably attached to the base having the cutting blade, so that the holder member is displaced by the operation of pulling out the tape, and the tape is cut. At this time, the holder member can be returned to the initial position. Then, the tape fed out from the reel member is a first temporary fastening portion provided on the holder member, and a second temporary fastening portion provided on the swing member connected to the holder member and the base by the link bar. When, since to be able to temporarily fastened at two locations, when the holder member is displaced by pulling the tape, can be passed stretched tapes between the temporary engaging portion.

When the tape is cut, the holder member returns to the initial position so that the separated temporary holding portions approach each other. At this time, the tape portion stretched between the temporary holding portions bends, The tape is folded when the adhesive surfaces come into contact with each other. By making this folded portion a knob when pulling out the tape, the next tape cutting operation can be performed smoothly.
Since the holder member temporarily holding the tape is separated from the cutting blade in a state where the tape is temporarily fixed by releasing the tension when the tape is cut, the tape does not continue to adhere to the cutting edge. Thereby, it can prevent that the performance of a cutting blade falls.

As described above, according to the present invention, the holder member is attached to the base in a displaceable manner, and the base and the holder member are each provided with a temporary holding portion for temporarily fastening the drawn tape. The knob can be made by the same operation as the cutting operation in the conventional tape dispenser, in which the tape is pulled out and cut, and the performance of the cutting blade can be prevented from being lowered.
The tape dispenser according to claim 2 attaches the holder member to the base so as to be rotatable, and temporarily fixes the drawn-out tape to the upper end of the attachment portion provided at the front end of the holder member in the tape drawing direction. Since the first temporary anchoring portion is provided, the swinging member having the second temporary retaining portion at the upper end is pivotally supported on the base, and the swinging member and the mounting portion are rotatably connected. It is possible to smoothly perform a series of operations of pulling out, temporarily fixing, and cutting.
A tape dispenser according to a third aspect of the present invention provides a blade tip by providing a plurality of depressed portions at predetermined intervals at an edge portion of one end of the planar cutting blade, and between the blade tip and the second temporary holding portion. Since a predetermined interval is provided, the tape is cut at the corner formed by the recessed portion and the edge portion of the blade edge while the tape is pulled out toward the blade edge and temporarily secured at two locations, and the cut line is edged. It can be cut in a straight line while creasing at the part. In particular, by providing a predetermined interval between the blade edge and the second temporary holding portion, it is possible to create a region where contact between the adhesive surfaces is avoided. By using this region, it is possible to peel off the bonded knob portion, and it is possible to attach the entire surface to an object to be bonded in the same manner as a normal tape.

  A preferred embodiment of the present invention will be described with reference to the accompanying drawings. In addition, embodiment is not limited to the following forms, Other aspects can also be implemented if the subject of this invention can be solved.

FIG. 1 is a front view showing a tape dispenser 1 according to a first embodiment of the present invention.
The tape dispenser 1 is capable of forming a knob 3 for the next cutting operation when cutting the adhesive tape 2, and includes a base 10 having a cutting blade 4 at the tip, a base 10 The slide member 20 is slidably attached to the table 10, the reel unit 30 is pivotally fixed to the slide member 20, and a folding mechanism 40 for folding the tape.

As shown in FIG. 2, the base 10 includes a pedestal 11 with a built-in weight, a rail 12 provided on the upper surface of the pedestal 11, and a front wall 13 with a cutting blade 4 attached to the upper end. , And the side wall portions 14 on both sides thereof. The side wall portions 14 and 14 are provided with pivoting portions 45 for attaching the folding mechanism 50.
A slide member 20 is slidably provided on the rail portion 12 on the upper surface of the pedestal portion 11. The slide member 20 functions as a holder member that holds the tape roll 2 ′ via the reel portion 30.

As shown in FIG. 3, the slide member 20 is biased in a direction away from the cutting blade 4 by a spring 15 interposed between the slide member 20 and the front wall portion 13 of the base 10. Due to the pulling force, the base 10 is moved forward (that is, the tape drawing direction A).
At the upper end portion of the front wall portion 21 of the slide member 20, a first temporary holding portion 41 for temporarily fastening the adhesive tape 2 drawn toward the cutting blade 4 is provided.

Bearings 23 are provided on the side wall portions 22, 22 on the front side and the back side of the slide member 20, and the reel portion 30 is rotatably attached to the bearings 23.
A tape roll 2 ′ with an adhesive applied on the inner surface is attached to the reel portion 30, and the tape 2 is drawn out by holding the knob 3 at the tip of the tape 2. At this time, the slide member 20 is designed to be slid toward the cutting blade 4 against the urging force of the spring 15.

Then, while moving the slide member 20, the tape 2 is pulled out in the direction of the cutting blade 4 by a desired length and cut by the cutting blade 4, but it is folded between the slide member 20 and the base 10. By providing the mechanism 40, the end portion of the cut tape 2 is folded back inward, and the knob portion 3 for the next cutting operation is formed.
Below, the structure of the folding mechanism 40 for folding the edge part of the tape 2 is demonstrated.

The folding mechanism 40 includes a slide portion 20 including a first temporary retaining portion 41 for temporarily fastening the adhesive tape 2 drawn toward the cutting blade 4, and a second temporary retaining portion 42. The swing member 43 is configured by a link bar 44 that is rotatably connected to the swing member 43.
That is, a first temporary retaining portion 41 for temporarily securing the drawn adhesive tape 2 is formed at the upper end portion of the front wall portion 21 of the slide member 20, and the tape 2 is formed at the upper end portion of the swing member 43. A second temporary anchoring portion 42 for further temporarily fixing is formed. The length (L) between the temporary holding portions is designed according to the size of the knob 3.

The swing member 43 is pivotally attached to the side wall portion 14 of the base 10 via a pivoting portion 45 provided at the lower end portion, and the slide member 20 moves in the front-rear direction to link. The bar 44 rotates, and the second temporary holding part 42 provided at the upper end part is configured to be separated from the first temporary holding part 41.
When the link bar 44 is connected at a substantially intermediate portion between the pivot stop portion 45 and the rotation end portion (second attachment portion 42) like the swing member 43, the first temporary holding portion 41 and the second temporary retaining portion 41 The length (L) between the temporary retaining portion 42 can be approximately double the moving distance of the slide member 20. For this reason, the tape dispenser 1 which can form the knob | pick part 3 of sufficient length is realized, although it is compact size.

The lengths of the rail 12 and the spring 15 of the base 10 are designed according to the moving distance of the slide member 20 and the like.
The usage state of the tape dispenser 1 having the above structure will be described with reference to FIGS.
First, from the initial state of FIG. 3A, the knob 3 is pulled and the tape 2 is fed out from the reel 30. Then, the tape 2 is pulled out while the slide member 20 is moved in the pulling direction (A).

Due to the displacement of the slide member 20, the spring 15 between the slide member 20 and the base 10 is compressed and biased. At the same time, the swing member 42 swings, and the second temporary retaining portion 42 at the upper end moves in a direction away from the first temporary retaining portion 41 (see FIG. 3B).
Since the swing member 43 is connected to the front wall portion 21 of the slide member 20 via the link bar 44, the second temporary holding portion 42 is longer than the moving distance of the slide member 20, and at a high speed. The first temporary holding part 41 is separated.

In this way, after the tape 2 is pulled out to a desired length, as shown in FIG. 3C, the first temporary holding portion 41 located on the reel portion 30 side and the cutting blade 4 side are arranged. Temporary fastening is performed at two locations with the second temporary fastening portion 42 located. And as shown in FIG. 4, when it cut | disconnects with the cutting blade 4 of the front-end part of the base 10, the ring-shaped knob | pick part 3 will be formed.
That is, when the tape 2 is cut, the spring 15 in the compressed state is restored and the slide member 20 is displaced to the initial position, but the swinging member 43 connected to the slide member 20 via the link bar 44 is rotated. Then, the second temporary holding part 42 at the rotating end is brought close to the first temporary holding part 41.

At this time, the tape part 3 ′ stretched between the first temporary holding part 41 and the second temporary holding part 42 is bent, and the tape part 3 ′ is brought into contact with each other on the inner side surface and is picked. Part 3 is formed.
According to the tape dispenser 1 of the present embodiment, the slide member 20 is provided on the base 10 provided with the cutting blade 4, the reel portion 30 for feeding the adhesive tape 2 is provided on the slide member 20, and the slide member 20 is provided. Since the spring 15 is biased in the direction away from the cutting blade 4, the slide member 20 is displaced by the operation of pulling out the tape 2 from the reel portion 30, and the tape 2 is fed out to a desired length. It is possible to temporarily hold each of the temporary holding portions 41 and 42 while confirming the above.

For this reason, it is possible to pull out the tape 2 while carefully checking the required length, carefully fix it, and carefully cut it.
When the tape 2 is cut, the biased spring 15 is elastically deformed, and the slide member 20 returns to the initial position. At this time, the temporary holding portions 41 and 42 in the separated state come close to each other, and the tape portion 3 ′ stretched between the temporary holding portions bends to bring the adhesive surfaces into contact with each other.
Since the ring-shaped knob 3 is thus formed, it is possible to make the knob 3 for the next cutting operation by the same operation as the cutting operation by a normal tape dispenser.

After the tape 2 is cut, the second temporary holding part 42 moves in a direction away from the cutting blade 4 as the slide member 20 returns, so that the cut tape 2 is peeled off from the cutting blade 4. be able to.
In particular, the first temporary holding portion 41 is provided at the upper end of the attachment portion (21) provided at the front end portion in the pulling direction of the slide member 20, and the swinging member 43 having the second temporary holding portion 42 formed at the upper end is provided. Since the swing member 43 and the attachment portion (21) are pivotally connected to the base 10 by the link bar 44, the knob portion having a desired length can be adjusted by adjusting the connection position. 3 can be formed.

In the present invention, the folding mechanism can be simplified. For example, like the folding mechanism 40 ′ of the tape dispenser 1 ′ shown in FIG. 5, the first temporary retaining portion 41 ′ for temporarily fastening the adhesive tape 2 drawn toward the cutting blade 4 is used as a base. While projecting to 10 ′, a second temporary retaining portion 42 ′ may be provided on the slide member 20 ′.
In this case, the pedestal portion 11 ′ of the base 10 ′ is provided with a rail 12 ′, a first attachment portion 16 provided with a first temporary retaining portion 41 ′ at the upper end, and a slide member 20 ′. A holding portion 17 for holding the tension spring 15 ′ is provided between them.

A second temporary retaining portion 42 ′ is provided at the upper end of the front wall portion 21 ′ of the slide member 20 ′. And a tension spring 15 ′ interposed between the front wall 21 ′ and the holding member 17 is held in a gap between the side wall 22 ′ and the base 10 ′.
By pulling out the tape 2 while picking the knob 3 from the initial state of FIG. 5A, the tape 2 is pulled out while the slide member 20 ′ is slid in the drawing direction A.

At this time, the spring 15 ′ between the slide member 20 ′ and the base 10 ′ is pulled, and the second temporary retaining portion 42 ′ of the slide member 20 ′ becomes the first temporary provision provided on the base 10 ′. It leaves | separates from the clip part 41 '(refer FIG.5 (b)).
Then, the base 10 is temporarily fixed at two locations, ie, a first temporary holding portion 41 ′ located on the reel portion 30 side and a second temporary holding portion 42 ′ located on the cutting blade 4 side. It cut | disconnects with the cutting blade 4 of front end part of '.

By cutting the tape 2, as shown in FIG. 5 (c), the tensioned spring 15 ′ is restored, and the slide member 20 ′ is displaced to the initial position. At this time, the tape portion 3 ′ stretched between the first temporary holding portion 41 ′ and the second temporary holding portion 42 ′ in a tensioned state is bent, and the inner side surfaces are in contact with each other.
As a result, the tape 2 is folded to form the knob 3.

Also in the tape dispenser 1 ′ of this aspect, the slide member 20 ′ is provided on the base 10 ′ provided with the cutting blade 4, the reel member 30 for feeding the adhesive tape 2 is provided on the slide member 20 ′, and the slide member Since 20 ′ is urged away from the cutting blade 4 by the spring 15 ′, the tape 2 is pulled out to a desired length from the reel portion 30, and then provided on each of the base 10 ′ and the slide member 20 ′. In the temporary retaining portions 41 ′ and 42 ′ thus obtained, the tape 2 can be carefully fastened and then cut.
When the tensile force of the tape 2 is released by cutting, the temporary holding portions 41 ′ and 42 ′ in the separated state come close to each other, and the tape portion 3 ′ is bent to form the knob portion 3. Since the tape 2 is peeled off, the adhesive can be prevented from sticking to the blade edge.

Further, when the tape 2 is cut as in the tape dispenser 1 ″ shown in FIG. 6, a predetermined length interval (M) is provided between the second temporary holding portion 42 and the cutting blade 4 ′. Alternatively, see FIG. 6B.
At this time, for example, it is preferable to provide a cutting blade 4 ′ having a structure of cutting at one edge portion of the flat portion at the upper edge of the front wall portion 13 of the base 10.

This cutting blade 4 ′ is designed so that the tape 2 can be cut linearly, and as shown in FIG. 7, the edge 4a is constituted by an edge.
That is, the blade edge 4a is configured by providing a plurality of depressed portions 4c at predetermined intervals on the edge portion of one end of the planar cutting blade 4 ′. The tape 2 is cut at a corner 4c formed by the depressed portion 4b and the edge portion, and the tape 2 is lined along the edge portion to reach the next depressed portion 4b. By repeating this, the tape 2 is cut linearly.
If the cutting blade 4 ′ having this structure is used, a predetermined length interval (M) can be ensured in the plane portion up to the blade edge 4a (see FIG. 8).

In use, from the initial state of FIG. 6 (a), after pulling the knob 3 and pulling out the tape 2 to a desired length, the first temporary holding part 41 located on the reel part 30 side After temporarily fastening at two places with the second temporary retaining portion 42 located on the cutting blade 4 side, the cutting edge 4a is cut through the flat portion of the cutting blade 4 '.
When the tape 2 is stretched between the temporary holding portions, as shown in FIG. 9, a predetermined length (M) can be provided between the cutting edge 4a and the second temporary holding portion 42, The region (3a) is a region from the tape end 2a to the second temporary anchoring portion 42 (see FIG. 10).

For this reason, when the 2nd temporary attachment part 42 adjoins to the 1st temporary attachment part 41, it avoids that adhesion surfaces contact (refer FIG. 11). The area where contact is avoided is a part having an adhesive function as a tape.
According to the tape dispenser of this aspect, it is possible to form the knob portion 3 in a state in which the adhesive region 3a having a predetermined length is provided at the end 2a of the adhesive tape 2. By using the adhesive region 3a, the adhesive portion 3a It is possible to peel off the state knob 3.

  That is, as shown in FIG. 12, first, the tape 2 is attached and fixed to an object to be bonded with the knob 3 held, and then the bonding area 3a at the end is pulled to bond the knob 3 The surface can be peeled off. As a result, like the normal adhesive tape 2, the entire surface can be attached to the adherend.

FIG. 13 is a front view showing a tape dispenser 101 according to the second embodiment of the present invention.
This tape dispenser 101 is also capable of forming the knob portion 3, and includes a base 110 having a cutting blade 4 at the tip, and a rotating member 120 rotatably attached to the base 110. The reel unit 30 pivotally supported by the rotating member 120 and the folding mechanism 40 for folding the tape 2 are configured.
