Description

  The present invention relates to a strip-like adhesive tape used for attaching packaging, paper, and the like, and a strip-like adhesive tape used for temporary fixation such as fixing of a container and a lid, binding of a bundle of food packs, and the vicinity of the center in the short direction In addition, a plurality of cuts or a set of cuts are continuously formed at intervals along the longitudinal direction of the pressure-sensitive adhesive tape, and have an easy-to-cut “push-cut pressure-sensitive adhesive tape” and “push-cut pressure-sensitive adhesive tape manufacturing apparatus” ".

Conventionally, cutting of a strip-shaped adhesive tape has been performed using a cutting tool such as scissors or a tape cutter, or by screwing the adhesive tape with a finger.
However, it may be difficult for a child to use a cutting tool. In addition, when the cutting tool is not at hand, if you try to thread it with your finger, the adhesive tape may adhere to each other if it cannot be cut due to poor hand cutting properties of the adhesive tape or even if it can be cut. Cutting took a lot of time and was cumbersome.
Adhesive tape has also been used for temporary fixing, such as fixing containers and lids, bundling bundles of food packs, and sealing lids on cardboard boxes. There was a risk of damaging the product.
In order to avoid such a situation, a technique has been developed in which a cutting part such as a perforation is provided on the adhesive tape to facilitate cutting, and several inventions have already been disclosed in this regard.

Patent Document 1 discloses a device relating to an adhesive tape that can be cut to a predetermined length under the name “adhesive tape having a cutting portion”.
The device disclosed in Patent Document 1 is provided with a perforated cut portion capable of cutting the tape body at regular intervals in the longitudinal direction of the tape body in which an adhesive is applied to at least one surface of the tape substrate. The present invention relates to an adhesive tape having a cutting part.
In the device having such characteristics, the adhesive tape can be reliably and easily cut without using a cutting metal fitting or the like by providing the cut portion in a perforated shape.

Next, Patent Document 2 discloses an invention named “easy tearable adhesive tape”.
The invention disclosed in Patent Document 2 is characterized in that a fine recess is formed on the entire surface of one side of a non-extensible and dimensionally stable plastic film, and an adhesive layer is provided on at least one side of the film. And
In the invention having such a configuration, it has a strength that can withstand the tensile strength applied during the packaging operation and the like, and has an end tear resistance that can be easily cut from the end portion without requiring a cutting tool.

Patent Document 3 discloses a device named “strong adhesive tape with a cut”.
The device disclosed in Patent Document 3 is characterized in that cuts are provided at an angle of 20 degrees or less from the side surface of the strong adhesive tape, and the cuts are alternately provided from both side surfaces.
In the strong adhesive tape having such a configuration, the adhesive tape can be easily cut from the side surface by providing the cut.

Patent Document 4 discloses an invention relating to a pressure-sensitive adhesive tape that maintains hand-cut property and has improved tensile strength and the like, and a device for manufacturing the same, under the name “hand-cut adhesive tape and its manufacturing device”.
The invention disclosed in Patent Document 4 is a pressure-sensitive adhesive tape formed by providing a pressure-sensitive adhesive layer on one surface of a belt-shaped plastic film substrate, and forming continuous holes at regular intervals along the longitudinal direction. It is a shape that does not have a corner, and is provided on the inner side of 1.5 mm or more from the side edge of the tape.
In the hand-cut adhesive tape having such a configuration, the hand-cut performance is not impaired, and there is no portion where stress is concentrated in the manufacturing and handling operations in each hole, so that the tensile strength and the tensile elongation are improved.

Patent Document 5 discloses an invention relating to an easily-cut adhesive tape that is called “adhesive tape” and prevents unintentional cutting of the adhesive tape and can be easily cut with a weak finger force.
The invention disclosed in Patent Document 5 is characterized in that a scar is provided along the longitudinal direction of the tape on the inner side away from the edge of the adhesive tape having an arbitrary width made of a plastic film.
In the adhesive tape having such a configuration, since the scar as a starting point of cutting is given at an inner position away from the end edge of the tape, there is no decrease in the strength of the end edge of the tape. Alternatively, the disadvantages of unintentional cutting from the end edge due to excessive tension, fluctuating tension, and oblique tension, which have been a problem with the prior art easy-cut adhesive tape having a scar near the end edge, are greatly improved.

Patent Document 6 discloses a device relating to an adhesive tape that can be easily separated by hand after applying the tape under the name "perforated general-purpose adhesive tape".
The device disclosed in Patent Document 6 is characterized in that a perforation is made in the length direction of the tape near the center of the width of the general packaging pressure-sensitive adhesive tape.
In the perforated general packaging pressure-sensitive adhesive tape having such a configuration, a plurality of cardboard boxes are arranged, and a plurality of boxes are connected by attaching the pressure-sensitive adhesive tape to the seam. Therefore, these can be transported together and can be easily separated by tapping the perforation of the tape with a hand.

Japanese Utility Model Publication No. 7-1053 JP-A-8-199123 Japanese Utility Model Publication No. 1-153350 JP 2008-189865 A JP-A-11-005956 Japanese Utility Model Publication No. 62-83840

In the device disclosed in Patent Document 1, the adhesive tape can be reliably and easily cut without using a cutting metal fitting or the like by providing a cut portion provided with a perforated slit.
However, since the film base material of the adhesive tape used for packaging, fixing the container and lid, bundling a bundle of food packs, attaching paper, etc. is thin, this method cannot ensure the tensile strength and breaks. Further, when cutting with fingers, it is necessary to insert both incisions and sandwich the portions that are not the incisions on both sides with fingers to screw the tape, so both hands are required. Therefore, when one hand is blocked during the work, the work must be interrupted and the work must be resumed after cutting the tape, and it may not be easy to cut the adhesive tape. In addition, since the finger touches the adhesive surface, the trace of the fingerprint may remain on the adhesive tape and impair the appearance. Furthermore, it may be difficult for the adhesive tape to get entangled with fingers after cutting and to stick the adhesive tape.

Next, the invention disclosed in Patent Document 2 has an endurance resistance that can withstand the tensile strength applied during packaging operations and the like and can be easily cut from the end without the need for a cutting tool. Have
However, in order to improve the hand cutting property of the film, the side end portions of the base film have a large formation density of the concave portions. On the other hand, the central region in the width direction is formed with a coarser density than the side end portion against the tensile force. Therefore, the hand cutting property is good mainly at the side edge of the base film, and when the side edge of the base film is first torn, depending on the direction, the center does not cut and only the side edge is separated. there's a possibility that. In order to prevent this, as in the device disclosed in Patent Document 1, it is necessary to securely pinch a portion to be cut with fingers and screw the tape, which may be complicated. Therefore, there is a possibility that work efficiency may be reduced. In addition, since fine concave portions are formed on the entire surface, printing on the tape surface may be affected.

In the device disclosed in Patent Document 3, the adhesive tape can be easily cut from the side surface by providing the cut at an angle of 20 degrees or less.
However, since the side edge is cut, the adhesive tape is very easily cut by the force applied to the side edge. For this reason, when a film base material is peeled off from the wound body of the adhesive tape, if a force is applied to the side edge portion, it tears and is difficult to peel off from the wound body.

In the invention disclosed in Patent Document 4, hand cutting performance is not impaired, and tensile strength and tensile elongation are improved.
However, since there is no portion where stress is concentrated during the handling operation, it is conceivable that the cutting direction of the tape is not constant. Therefore, it may not be cut as desired, and a new cutting tool or the like may be required, and it cannot be said that the hand cutting property is maintained. Furthermore, since there is a slit near the side edge portion of the adhesive tape, the side edge portion may be separated during handling and cling to the hand, resulting in poor workability. In addition, the slit affects the appearance quality of the adhesive tape and the printing on the tape surface.

  In the invention disclosed in Patent Document 5, the adhesive tape is pushed from above and cut in the same manner as in the present application. As in the case of adhesive tape, in which there are 7 rows of staggered marks at 0.5 mm intervals along the short direction, this cutting method is unspecified by the force of pushing from above to cut perforations. It is a method of cutting by connecting scars to be cut. This adhesive tape has many scars in the immediate vicinity of the cut end, so when peeling the adhesive tape's cut end from the roll, force is applied to the scar near the cut end and the adhesive tape cuts vertically and can not be used. High nature. Moreover, when this adhesive tape is used for temporary fixation, there is a high possibility that the adhesive tape will be cut along the scar group by an unintended force.

  In the device disclosed in Patent Document 6, a perforation is formed at the center in the short direction of the packaging adhesive tape, and the cardboard boxes connected by cutting from the perforation are separated. . Since this adhesive tape is cut using a perforation, it may be easily cut by an external force during transportation. Furthermore, since it is necessary to match the seam and the perforation of the cardboard box, care must be taken when connecting the boxes.

The main problem to be solved when cutting an adhesive tape without using a cutting tool as described above is that a tensile strength can be secured while being cut by a simple operation. Also, do not touch the adhesive surface when cutting, and only the side edges will not be cut, the adhesive tape will not cut unintentionally when cutting or peeling the adhesive tape from the roll, etc., maintaining the appearance quality of the adhesive tape In addition, the adhesive tape used for temporarily fixing the article is difficult to break except when the article is unfixed, and is easily released when necessary.
In order to solve at least one of the above problems, the present invention provides an adhesive tape that can be easily cut at any position in the longitudinal direction of the adhesive tape by pressing the surface of the adhesive tape from above with a fingertip or a nail. The purpose is to provide. It is another object of the present invention to provide a pressure-sensitive adhesive tape that can be adjusted by adjusting its tensile strength and ease of cutting. It is another object of the present invention to provide an adhesive tape manufacturing tool for pressing and cutting.

To achieve the above object, an invention according to claim 1, comprising an adhesive layer on at least one surface of the strip-like film substrate, a pressure-sensitive adhesive tape cut Oshide, along the longitudinal direction of the strip-like film substrate, a plurality Incisions having a length of not less than 0.3 mm and not more than 3 mm are continuously arranged at intervals to form a row, and this row is provided in the center in the short direction of the strip-shaped film substrate , Further, the longitudinal direction of the cuts penetrating therewith is formed at an angle α (10 degrees ≦ | α | ≦ 60 degrees) with respect to the longitudinal direction of the strip-shaped film substrate.
In addition, in this application, a strip | belt-shaped film base material points out the support body of an adhesive tape, and the center of a transversal direction is a concept also including a substantial center or center vicinity.

In order to cut the adhesive tape to be pressed and cut according to claim 1, an arbitrary portion in the longitudinal direction of the adhesive tape to be pressed and cut is fixed by hand or fixed to an object, and the center in the short direction of the adhesive tape to be pressed and cut. Press near the top of the band-shaped film base with the tip of your finger or the nail. As a result, a pulling force is generated between the fixed part and the pressed part of the pressure-sensitive adhesive tape to be pushed and cut. This pulling force becomes a force that expands the cut itself made in the center in the short direction of the belt-like film substrate. In addition, since the band-shaped film substrate has some extensibility, the notch becomes difficult to expand as it moves away from the pressed part,
The notch closest to the pressed part begins to expand. Furthermore, since the force which pulls an adhesive tape to a longitudinal direction is acting, a notch expands toward the both-sides edge part of the transversal direction of the adhesive tape to push and cut. Therefore, the adhesive tape that is pushed and cut at the time of cutting does not tear in the longitudinal direction. Further, since the cut is formed at the center in the short direction of the pressure-sensitive adhesive tape to be pushed and cut, only the side edge portion is not cut as in Patent Document 4.
Further, in the pressure-sensitive adhesive tape of the present invention, since only one notch is involved in the cutting, the notches adjacent to each other along the short direction of the pressure-sensitive adhesive tape as in the perforated notch part in Patent Document 1 are used. There is no need to be close and easy to connect.

  Furthermore, in order to expand the notch to push and cut the adhesive tape, it is necessary to apply a strong local force to the notch or its periphery. Therefore, it is necessary to press the surface of the adhesive tape with the tip of the finger or the nail portion. Furthermore, since the pressure-sensitive adhesive tape is kinked to release the force when pressing the surface near the side edge of the pressure-sensitive adhesive tape, it is easier to apply the force by pressing the center of the pressure-sensitive adhesive tape. Therefore, the cut is arranged at the center in the short direction of the adhesive tape. Further, a plurality of cuts are continuously arranged at intervals along the longitudinal direction so as to be cut at any part of the adhesive tape.

It should be noted that a force that pulls in the longitudinal direction acts on the adhesive tape that is pushed and cut when it is peeled off from the wound body, used, or manufactured. The pressure-sensitive adhesive tape to be pushed and cut is required to have a tensile strength that is not cut by this pulling force and to be easily cut by pressing the pressure-sensitive adhesive tape surface.
The required tensile strength and ease of cutting when the surface of the adhesive tape is pressed differ depending on the actual usage situation and purpose of use. This will be described below.

The present invention cuts the adhesive tape by expanding the cut. However, when the cut angle α is 0 degree, even if the adhesive tape is pulled in the longitudinal direction, the cut is not expanded, so that the tensile strength hardly decreases. In the case where the length of the cut is the same, the absolute value of the angle α increases from 0 degree, that is, as the longitudinal direction of the cut approaches a state parallel to the short direction of the adhesive tape, the cut is easily expanded and the tensile strength is descend. When the absolute value of the angle α is 90 degrees, the tensile strength is the lowest. In addition, according to the experimental results described later, the angle α is 10 degrees ≦ | α | ≦ as a range in which the tensile strength is significantly higher than that when the absolute value of the angle α is 90 degrees and can be cut. It is desirable to be 60 degrees.
In addition, the angle of a notch does not need to be constant in several notches, and may differ for every notch.

  On the other hand, if the notch angle α is the same, the longer the notch length is, the easier it is to be expanded and the easier it is to cut, but if it is too long, the tensile strength decreases. Conversely, the shorter the cut length, the stronger. For example, when the cut angle α is 90 degrees, in order to ensure the tensile strength, the length of the cut can only be shortened. However, if the cut angle α is too short, the cut is difficult to expand, and one cut that is a feature of the present invention is provided. It becomes difficult to expand and cut. Therefore, specifically, the length of the notch is 0.3 mm or more and 3 mm or less, preferably 2 mm or less. The reason for this is that, with a tape such as a general OPP film, it is difficult to extend the cut with a cut of less than 0.3 mm, and it is difficult to deform and cut the tape, but the cut is about 5 mm. As a result, the tensile strength is greatly reduced. Furthermore, if the cut is long, even if one side of the cut is peeled off when it is peeled off from the wound body or the like, the other side remains on the wound body and is easily torn from the cut part. In particular, such a phenomenon occurs as the cut direction is closer to 90 degrees with respect to the peeling direction in the case of peeling diagonally. Therefore, it is desirable that the thickness is 0.3 mm or more and 3 mm or less, preferably 2 mm or less. Furthermore, 2 mm or less is preferable because cutting is possible when the length of the cut is 0.3 mm or more, and therefore it is desirable that the dimensions be as short as possible to ensure the tensile strength without selecting the tape material. is there.

Since the strip-like film base material of the pressure-sensitive adhesive tape to be pushed and cut has some elasticity, the cut becomes difficult to expand as the position where the cut is pushed away from the cut, and the pressure-sensitive adhesive tape to be pushed and cut becomes difficult to cut. For this reason, it is better that the interval between the cuts in the longitudinal direction is narrow. However, as described above, the pressure-sensitive adhesive tape is not cut in the longitudinal direction when it is cut. May be connected in the longitudinal direction and cut vertically. In order to prevent such vertical cuts, specifically, the interval between the cuts in the longitudinal direction of the pressure-sensitive adhesive tape is not less than 1 times the cut length, and is preferably at least 2 mm.
The reason is that the adhesive tape is likely to be cut in the longitudinal direction at an interval shorter than the length of the cut and is in a so-called vertical cut state. Furthermore, in the experimental results by the inventor, with a general material such as OPP tape, the tape width was cut into 1 mm width and 2 mm width, and as a result of performing a tensile test, it became long and difficult to cut at 2 mm width. Even when the length is short, it is desirable that there is an interval of about 2 mm.
Here, the interval between the cuts in the longitudinal direction refers to the shortest interval in the longitudinal direction between the ends of the cuts adjacent to each other in the longitudinal direction.

  In addition, in order to form a plurality of cuts continuously, in addition to being formed at equal intervals along the longitudinal direction of the pressure-sensitive adhesive tape to be pushed and cut, a plurality of cuts were formed at equal intervals. There is also a case where a portion of a certain length without a cut is connected and this combination is repeated. By continuous formation of such cuts, the adhesive tape that is arbitrarily pushed and cut at the intended position is cut.

The notches in claim 1 refer to those in which a part of the film substrate is simply notched in the thickness direction, and means that there is no opening and no area. Therefore, it does not include those formed by deliberately removing a part of the film base material, but it does not include those formed with a certain area, but a slight area generated when the film base material shrinks at the time of cutting with a laser or the like The opening is included in the notch in claim 1. Moreover, although the notch which penetrates means what penetrated the film base material, it does not exclude the slightly unpenetrated notch generated when the actual notch is formed.
The shape of the cut includes not only a straight line but also an indeterminate form formed by a curve or a protrusion.

Since the cut has almost no opening area compared to a hole having an opening area, the adhesive layer is less likely to leak onto the surface of the film. Therefore, it is difficult to get sticky or dirty. In addition, the appearance quality can be maintained because the cuts do not become noticeable because they are not dirty. Further, if a part of the film base material is removed as a hole, it is not desirable because the removed base material needs to be processed, and a notch is desirable.
In the pressure-sensitive adhesive tape having the above structure, the longitudinal strength of the pressure-sensitive adhesive tape to be cut and the pressure of the pressure-sensitive adhesive tape to be cut by pressing are adjusted by adjusting the length of the cut, the angle of the cut, and the interval in the longitudinal direction of the cut. Ease can be adjusted. The tensile strength and ease of cutting are adjusted to suit the purpose and method of use.

Next, the invention described in claim 2 is a pressure-sensitive adhesive tape provided with an adhesive layer on at least one surface of the belt-like film substrate, and has a plurality of penetrating lengths along the longitudinal direction of the belt-like film substrate. Cuts having a length of 0.3 mm or more and 3 mm or less are continuously arranged at intervals to form a row, and each row has a length from the center in the short direction of the strip-shaped film substrate to two side edges. Within a range of / 3, a plurality of rows are formed that are continuously arranged at intervals along the longitudinal direction of the belt-like film substrate, and these rows are 1.5 times or more the length of the cut. Are provided at intervals of at least 3 mm, and the cuts in the plurality of rows form a staggered arrangement with each other, and in some or all of the plurality of through cuts in the plurality of through cut rows , These slices Mino longitudinal angle alpha (10 degrees ≦ ≦ 60 degrees | | alpha) to the longitudinal direction of the strip-like film substrate, characterized in that it is formed with.

As the width of the adhesive tape that is pushed and cut increases in the short-side direction, the position of pressing with the fingertip or nail from above may vary from the vicinity of the center to the periphery.
In addition, since the belt-like film base material has some extensibility, the force for expanding the cut becomes weaker as the distance from the place where the force is applied. Therefore, by arranging multiple rows of notches within the range of 2/3 each of the length from the center in the short direction of the strip-shaped film base to both side edges, even if the pressing position varies, any of the notches Sufficient force can be applied to the surface to stably cut. In addition, what is in the range of about 2/3 is also included in the range of 2/3.
Further, when the space between the rows of cuts is pushed with a fingertip or a nail, the cuts are expanded even when the absolute value of the angle α is small, so that the necessary tensile strength can be ensured and it is easy to cut.
Since notches are not arranged near both side edges, only the side edges are not cut when the adhesive tape is peeled from the wound body as in the case of claim 1.
In addition, it arrange | positions continuously along the longitudinal direction of a strip | belt-shaped film base material in the range of each 2/3 of the length from the center of the transversal direction of a strip | belt-shaped film base material to a both-sides edge part. In addition to the row parallel to the longitudinal direction of the belt-like film substrate, the row includes a row meandering within the range of 2/3 each of the length from the center in the short direction of the belt-like film substrate to both side edges. .

  If the longitudinal direction of the cut is an angle α (10 degrees ≦ | α | ≦ 60 degrees) with respect to the longitudinal direction of the strip-shaped film substrate, the angle may be different depending on the row, and the angle α is different for each cut. May be. As in the first aspect, the tensile strength does not decrease as the absolute value of the angle α decreases.

The mechanism for cutting the adhesive tape when the band-shaped film substrate is pressed with the fingertip from above is the same as in the first aspect, and only one notch is involved, so a perforation is formed in the short direction of the adhesive tape. There is no need. When pushing and cutting, since the direction of tearing is directed to both side edges by the force of pulling in the longitudinal direction of the adhesive tape, it is not cut zigzag in the longitudinal direction. Moreover, it is not necessary to control the direction of tearing by the arrangement of notches (interval between notches) and the direction of the notches (angle α).
However, in the case of the parallel arrangement in which the cuts are arranged side by side in the short direction, if the sign of the cut angle α is the same, some cuts may remain at the cut end of the tape. Cut remaining cut end of the tape, have Na desirable because cause unintended disconnection when peeling the adhesive tape from the winding body.
If there is no problem in use, such as a staggered arrangement in which the cuts are not arranged side by side in the short direction, or if the cut end of the adhesive tape is not often peeled off from the wound body, the cut angle α located on the right side from the center is- 10 degrees ≦ α ≦ −60 degrees, and the angle α of the cut located on the left side is not limited to 10 degrees ≦ α ≦ 60 degrees .

In order to prevent the longitudinal cut of the adhesive tape at the time of cutting or the like, specifically, the interval between the longitudinal cuts of the adhesive tape in the same row is preferably at least 1 mm of the length of the cut and at least 2 mm or more. .
In addition, when placing cuts in a staggered arrangement between different rows, the shortest distance from the cut end to the nearest cut end to prevent unintentional cuts when peeling the cut end of the adhesive tape from the roll Should be opened 2mm or more. For this reason, it is desirable that the longitudinal notch interval be 2 mm or more regardless of the row. However, this does not apply when there is no problem in use, such as not often peeling the cut end of the adhesive tape from the roll.
Specifically, the distance between the rows is preferably 1.5 times or more of the length of the cut, and more preferably at least 3 mm. In addition to the same reason as in the case where they are arranged in the same row, if the cuts between the rows are connected, it leads directly to the cutting of the adhesive tape, so the safety factor between the rows is 1.5 times. There is nothing else.
In this way, by providing a notch interval or a row interval, unintentional cutting is unlikely to occur when the cut end of the adhesive tape is peeled off from the wound body or at the time of cutting.

In the pressure-sensitive adhesive tape having the above structure, the number of rows of cuts, the interval between rows, the length of the cuts, the angle of the cuts, and the intervals in the longitudinal direction of the cuts are adjusted to adjust the length of the pressure-sensitive adhesive tape in the longitudinal direction. You can adjust the tensile strength and ease of cutting the adhesive tape. Incidentally, the tensile strength and cut ease the use purpose, Ru is adjusted to suit the method used.

Next, the invention described in claim 3 is a press-cut adhesive tape according to claim 1 or claim 2, wherein each of the slits penetrating is replaced by at least one row of continuous cuts. It is characterized by that.
The above-mentioned set of notches that are continuous in a perforated manner refers to those that are arranged in the same length as the notches on a straight line in the same direction as the longitudinal direction of the notches through which the minute notches penetrate rather than the notches penetrating.
Therefore, when a force is applied from above the pressure-sensitive adhesive tape to be pushed and cut, these fine cuts are connected (continuous) to form one cut that is substantially equal to the cut through. The subsequent cutting is the same as in the first aspect.
Therefore, by applying a local force from the fingertips and nails to the tape surface, one through notch that is almost equal to a set of minute notches that are continuous in a perforated manner is completed, and this notch is formed on the side edges of both ends of the adhesive tape. It has the effect of reaching and being cut.
Since the cut forming the perforation is very small, it is difficult to expand the cut even if the adhesive tape is pulled in the longitudinal direction. For this reason, compared to a single notch, a set of minute notches that are continuous in the form of a perforation having the same length has a strong tensile strength.

Furthermore, in the case of a set of minute cuts that are continuous in a plurality of rows of perforations, applying a force from above to the adhesive tape that is pushed and cut makes it easier to connect (continue) the minute cuts in the rows. It has the effect | action that it becomes easier to cut | disconnect than the case of.
However, the larger the number of rows of minute cuts, the greater the number of fine cuts that remain without being cut around the cut end of the adhesive tape.Therefore, unintentional cuts may occur when peeling the cut end of the adhesive tape from the roll. Easy to wake up. For this reason, the number of rows of cuts is determined according to the method of use of the adhesive tape, but the number of rows in the set of cuts is preferably two rows or one row.

The interval between the minute notches and the interval between the rows of minute notches are those that can be easily cut when a local force is applied from above to the adhesive tape to be pushed and cut.
In addition, it has the same action as the pressure-sensitive adhesive tape according to claim 1 or 2.

Furthermore, the invention described in claim 4 is an adhesive tape that is pressed and cut with an adhesive layer on one side of the belt-shaped film substrate, and has a length from the center in the short direction of the belt-shaped film substrate to both side edges. In each 2/3 range, along the longitudinal direction of the belt-like film substrate, a plurality of notches having a length of not less than 0.3 mm and not more than 3 mm are continuously arranged at intervals to form a row. The row is provided with one row or a plurality of rows, and at least one row of the plurality of through cuts among the plurality of through cuts, the longitudinal direction of these cuts is an angle with respect to the longitudinal direction of the strip-shaped film substrate. It is formed with α (10 degrees ≦ | α | ≦ 60 degrees), and the band-shaped film base material is characterized by having a part not including the adhesive layer in a part including the cut.
When an adhesive tape is used for temporarily fixing an article, releasing the fixation requires cutting the adhesive tape or peeling the adhesive tape from the article.
When an adhesive tape that is pushed and cut for temporary fixing is used, if the cut and the peripheral portion of the cut are adhered to other objects, the cut cannot be cut because the cut does not expand even if force is applied. However, by having a portion that does not include the adhesive layer in a part including the cut of the belt-shaped film substrate, the cut is expanded when a force is applied with a nail or a fingertip, and the adhesive tape is easily torn. Furthermore, since it is easier to cut the adhesive tape if the adhesive layer is not provided in the direction in which the cut is expanded, there may be a portion not provided with the adhesive layer in the peripheral portion including the cut and the side edge. On the contrary, since the complete cutting may not be necessary depending on the use of the pressure-sensitive adhesive tape to be pushed and cut, the peripheral portion including a part of the cuts and side edges may be provided with the pressure-sensitive adhesive layer.

Application of the pressure-sensitive adhesive layer to the belt-shaped film substrate is limited to one surface . For example, it is easier to manufacture the pressure-sensitive adhesive tape by applying up to about half the width in the short direction along the longitudinal direction of the pressure-sensitive adhesive tape. In such a case, in the adhesive tape having two rows of cuts on the left and right sides from the central portion in the short direction, the cuts do not expand and are not cut because one row sticks to what is bound. Thus, when it does not cut | disconnect by providing an adhesion layer, you may abbreviate | omit a notch from the meaning with which a notch is provided.
When the adhesive tape is peeled off from the article as a temporary release of the article, it is not adhered to the article unless there is an adhesive layer around the cut end, and this part is easily grasped and peeled off. If the length of the adhesive tape required for fixing the article is known in advance, cuts are made for each required length or for a certain length, and adhesive is applied from the notch and the periphery of the cut to one or both sides. Ru can be accomplished by having no layer.

In the pressure-sensitive adhesive tape according to claim 1 of the present invention, when a concentrated force from above is applied to the tape surface near the center of the pressure-cut adhesive tape by a fingertip, a nail or the like, one of the cuts arranged in the center. One stretches toward the side edge and the adhesive tape is cut. For this reason, it has the effect that it is hard to tear an adhesive tape to a longitudinal direction at the time of a cutting | disconnection.
In addition, since the operation at the time of cutting is simply performed by pressing the vicinity of the center of the adhesive tape in the short direction with the tip of the finger or the nail, even a child can perform it with one hand.
In addition, since the finger does not touch the adhesive layer of the adhesive tape at the time of cutting, the tape may adhere to the finger after cutting, making it uncomfortable or entangled, and leaving fingerprint marks on the adhesive tape Absent.
Further, even when the adhesive tape is not cut, such as when the adhesive tape is peeled off from the wound body, since the cut is near the center in the short direction of the adhesive tape, only the side edge portion is not cut.
Furthermore, although the tensile strength required for adhesive tapes and the ease of cutting differ depending on the purpose of use, the length and the angle α of the notch can be adjusted by considering the material and thickness of the adhesive tape film. Necessary tensile strength and ease of cutting can be secured. For example, as shown in FIG. 3A to be described later, since the length of the cut can be increased while ensuring the necessary tensile strength even if the angle α is reduced, a position slightly away from the cut is pushed. Even in this case, the adhesive tape can be cut. For this reason, the number of notches per unit area can be reduced. In this way, the pressure-sensitive adhesive tape that is pushed and cut can have various configurations, and thus has high versatility. In addition, the pressure-sensitive adhesive tape has a small cut and has almost no opening area, so it is excellent in appearance.
In addition, since the adhesive tape can be cut at a specific position by adjusting the interval between the cuts, it can contribute to cost reduction and product uniformity in applications such as always using a fixed length for industrial use. it can.
In addition, the pressure-sensitive adhesive tape can be cut very easily with local force in the vicinity of the cut, but on the other hand, if surface pressure is applied to the pressure-sensitive adhesive tape during transportation or handling, the cut will not occur. The adhesive tape is difficult to cut because it does not expand so much. The same applies when a local force is applied in addition to the vicinity of the notch. Furthermore, when a force is applied to the side edge portion of the adhesive tape, the tape is twisted to release the force, so that the adhesive tape is difficult to cut. For this reason, the pressure-sensitive adhesive tape of the present invention is suitable for temporarily fixing the lid of the container or for bundling food packs.

In the pressure-sensitive adhesive tape according to claim 2 of the present invention, since force acts on any one of the plurality of rows, even a wide pressure-sensitive adhesive tape having a width of 24 mm in the short direction is stable. Can be cut.
When the pressure-sensitive adhesive tape that is pushed and cut is used for temporary fixing, opening is facilitated. For example, when an adhesive tape that is pushed and cut to seal a cardboard box is used, the lid, the main body, and the lid are fixed. In the case of opening, the lid and the main body can be separated by starting to tear from any of the cuts by simply rubbing the periphery of the cut located in the gap between the lid and the main body with a nail. Subsequently, the lid can be easily opened by similarly performing the periphery of the joint between the lids.
In addition, the same advantageous effects as those of the pressure-sensitive adhesive tape to be pressed and cut according to claim 1 are obtained.

In the pressure-sensitive adhesive tape according to claim 3 of the present invention, since a force is required to connect the fine cuts constituting the continuous cuts in a perforated shape, the pressure-sensitive adhesive having one through cut. Compared with a tape, although the ease of cutting is slightly reduced, the tensile strength of the adhesive tape itself can be improved.
In addition, a set of notches that are continuous in a perforated shape can be formed by penetrating a thin film needle having a wedge-shaped tip or the like through the belt-like film base material, which facilitates processing operations and has a great merit in manufacturing. Furthermore, the effect on the appearance is small.
In addition, it has the same advantageous effect as the pressure-sensitive adhesive tape of claim 1 and 2.

When the pressure-sensitive adhesive tape to be pressed and cut according to claim 4 of the present invention is used for temporary fixation, it is necessary to release the fixation by cutting the adhesive tape or removing the adhesive tape. In cutting the adhesive tape, it is easy to cut because there is no adhesive layer in a part including the cut. For example, when used as a binding tape, if there is an adhesive layer around the cut at the time of cutting, the part to be cut may stick to the product and the cut does not expand and it may be difficult to cut. However, in the pressure-sensitive adhesive tape to be pressed and cut according to claim 4, since there is no pressure-sensitive adhesive layer in a part including the cut, it can be easily cut. Moreover, the cutting | disconnection in a specific intended place is attained by making the part which does not have an adhesive layer partially along a longitudinal direction. Moreover, when the periphery of the notch used for cutting does not have an adhesive layer, the peripheral portion of the cut end is not adhered to the article, so that this portion can be easily grasped and peeled off.
Further, the adhesive tape cutting press having a portion not provided with an adhesive layer on a portion including a notch is without adhesive material from the cut oozes to the tape surface, Ru can be kept high appearance quality.

  As described above, the present invention having the above-described configuration can cut the adhesive tape without touching the adhesive layer while ensuring the necessary tensile strength. And only the side edge part of an adhesive tape is not cut | disconnected, but it can cut | disconnect easily, without using instruments, such as scissors. Therefore, there is no stress and no discomfort during cutting. Further, since the cuts are small and unnoticeable, the influence on the appearance and printing is small. Furthermore, since the tensile strength and the ease of cutting can be adjusted, it can contribute particularly in the temporary fixing scene of the article.

An outline of the pressure-sensitive adhesive tape to be pressed and cut according to the present invention will be described with reference to FIGS. 1 to 5. In the following description of embodiments, examples, modified examples, and reference numerals in the drawings, “pressure-sensitive adhesive tape” is simply referred to as “pressure-sensitive adhesive tape”.
FIG. 1 is an external perspective view of an adhesive tape according to the present invention.
As shown in FIG. 1, an adhesive tape 1 according to the present invention has a wound body 5 and is provided with an adhesive layer 4 on the back surface of a film substrate 2, and the longitudinal direction in the center in the short direction of the film substrate 2. A plurality of slits 3 are continuously provided in a row at regular intervals. Further, the cut 3 penetrates the film base 2. The notch 3 may not necessarily be a complete center but may be formed near the center. That is, the center in the present application is a concept including a substantially center. In addition, the wound body 5 shows the state comprised by the adhesive tape 1 being wound by itself or around the core.
The film base 2 was formed into a belt shape by biaxially stretched polypropylene film (hereinafter referred to as OPP film) made of polypropylene, a synthetic resin such as acetate, or a film made of cellophane, or a plurality of layers. Things are used.

FIG. 2A and FIG. 2B are enlarged views of the cut of the adhesive tape according to the present invention, respectively.
As shown in FIG. 2A, the notch 3a having the length a provided in the adhesive tape 1a is provided with an angle α. The angle α is an angle formed by the longitudinal direction of the cut 3a and the longitudinal direction of the adhesive tape 1a. When the longitudinal direction of the cut 3 is parallel to the longitudinal direction of the adhesive tape 1a, the angle α is 0 degrees and parallel to the short direction. A certain case is set to 90 degrees or -90 degrees. In addition, the sign of the angle α is indicated by plus when the clock is clockwise and minus when it is counterclockwise.
FIG.2 (b) has shown the case where the notch 3b with which the adhesive tape 1b is equipped is provided continuously over 2 rows along the longitudinal direction of the adhesive tape 1b, and was provided over 2 rows. It is a schematic diagram for demonstrating the space | interval between the notches 3b. In FIG. 2 (b), b is the distance between the longitudinal cuts 3b in the same row, c is the distance between the two rows of the cut 3b, and d is the longitudinal distance between the upper and lower ends of the cuts 3b existing in different rows. , E is the distance in the longitudinal direction between the upper end and the upper end of the notches 3b existing in different rows. The positional relationship of the notches 3b is expressed by the shortest distances b, c, d, and e shown in the drawing. For example, when e = 0, that is, when the film substrate 2 is horizontally disposed in the lateral direction, the cuts 3b are in a parallel arrangement, and the others are in a staggered arrangement. In addition, in FIG.2 (b), the upper end of the adhesive tape 1b has shown the cut end when it cuts by pushing.
Next, specific measurement results of the relationship between the notch angle, tensile strength, and ease of breaking will be described.

FIG. 3A and FIG. 3B are graphs showing the relationship between the tensile strength and the cutting angle in the OPP film and the cellophane tape, respectively.
Here, the tensile strength refers to the difficulty of breaking when the adhesive tape is pulled in the longitudinal direction. In the measurement, a commercially available OPP adhesive tape having a width of 18 mm and a cellophane tape having a width of 20 mm were used, and the load (g) at the time of cutting the adhesive tape was taken as the tensile strength. The measurement was performed by changing the cut angle α. A specific measurement method will be described in detail below.

The cut was formed on an iron ruler using a craft cutter knife so as to have a predetermined length. When applying a thin oil and fat to the iron ruler and peeling off the tape, the tape sticks to the ruler so that the cut does not expand.
One notch was formed at the center in the short direction of the tape. One end of this tape is fixed to a round plate with a horizontal plate, and the other end is hung vertically. The end part of the adhesive tape hanging vertically was stuck on the peripheral surface of the cylinder. The distance to the plate on which the cylinder and the tape were fixed was about 4 cm. The spring and auxiliary weight are hung on this cylinder, and the spring is pulled down at a constant speed in the vertical direction. When the adhesive tape is cut, the scale of only the spring returns to 0, but the maximum value just before cutting was recorded by sandwiching the recording paper with the scale of only the spring. The cut angle α was changed every 10 degrees from 10 degrees or 20 degrees to 90 degrees, and the maximum value was repeatedly measured 7 to 25 times at the same cut angle. A value obtained by adding the weight of the auxiliary weight and the weight of the cylinder to the maximum value was expressed in grams and used as a measurement value of tensile strength.

The measurement result by the said measurement is as FIG. 3 thru | or FIG. In each case, the horizontal axis indicates the angle of cut α (degrees), and the vertical axis indicates the tensile strength (g).
First, FIG. 3A is a diagram showing an average value of measured values of tensile strength for each notch angle with respect to an OPP film having a notch length of 1 mm and an OPP film having a notch length of 5 mm. In this figure, when the cut length is 1 mm, the tensile strength is 1441 (g) when the angle α is 90 degrees. When the length is 5 mm, the tensile strength is comparable when the angle α is 20 degrees. That is, even if the angle α is reduced, the same tensile strength can be ensured by increasing the length of the cut.
FIG.3 (b) is a figure which shows the average value of the measured value of the tensile strength for every angle of a notch regarding the cellophane tape whose notch length is 2 mm. The statistical values of the measured values are shown in Table 1.

Next, FIGS. 4 (a) to 4 (c) show the tensile strengths of an OPP film having a cut length of 1 mm, an OPP film having a cut length of 5 mm, and a cellophane tape having a cut length of 2 mm, respectively. It is a figure which shows the relationship between a measured value and a notch angle.
These figures show the same measurement results as in FIGS. 3 (a) and 3 (b), and show the more detailed measurement results with the statistical values shown in Table 1. .
In FIG. 4 (a) to FIG. 4 (c), the measured values are represented by attaching a box plot and an average rhombus.
In the boxplot, the upper and lower ends of a rectangular box indicate 25% and 75% of the quantile, and the horizontal line in the box indicates the median median. A line extending up and down from the box is called a beard. The box-and-whisker plot shows the distribution of measured values. In the case of a normal distribution, the upper and lower ends of a rectangular box and the positions of 25% and 75% of quantiles are arranged at equal intervals across the median median. The measured value away from the whisker is an outlier. Since the measured values are not largely deviated from the normal distribution from the boxplot, the average value can be used as the representative value. The central horizontal line of the average diamond indicates the sample average, and the upper and lower ends of the diamond indicate the 95% confidence interval. The width of the diamond represents the number of samples (see Table 1 for specific sample numbers). It can be seen that there is no difference in the average value if the diamonds have the same tensile strength.
3A, FIG. 4A, FIG. 4B, and Table 1, in the OPP film, the tensile strength of the adhesive tape increases as the cut length a decreases.
Further, from FIG. 3A, FIG. 3B, FIG. 4A, FIG. 4B, FIG. 4C, and Table 1, in both the OPP film and the cellophane tape, the notch angle α The smaller the becomes, the stronger the tensile strength.

However, there is a possibility that there is no statistically significant difference in tensile strength when the cut angle α is 90 degrees to 60 degrees. In order to verify this, an angle α other than 90 degrees, in which a significant difference is obtained compared with the tensile strength when the cut angle α is 90 degrees, was obtained. This verification was performed by Tukey-Kramer HSD test. The results are shown in FIGS. 5 (a) to 5 (c) below.
FIGS. 5 (a) to 5 (c) show the tensile strength and cutting angle of an OPP film having a cut length of 1 mm, an OPP film having a cut length of 5 mm, and a cellophane tape having a cut length of 2 mm, respectively. It is a figure which shows the measured value of a relationship.
In these figures, the circle displayed at the right end is the result of Tukey-Kramer's HSD test. The circle is shown for each angle, and the center of the circle shows the average value of the angles. The smallest significant difference is indicated by the size of the circle. Therefore, if the circles do not overlap, it means that there is a significant difference in the average value with a risk rate of 5%. When the notch angle α is significantly different from the average value of the tensile strength of 90 degrees, the circles do not overlap and the font indicating the angle α of the horizontal axis is shown in italics. On the contrary, when the risk rate is 5% and there is no statistically significant difference in tensile strength, the circles are overlapped, and the angle α is also indicated by the same font as 90 degrees.
In the OPP film having a 1 mm depth of cut shown in FIG. 5A, no significant difference was observed in tensile strength when the angle of cut α was 90 degrees and 80 degrees, but a significant difference was observed at 70 degrees or less. In the OPP film having a cut depth of 5 mm shown in FIG. 5B, no significant difference was observed when the cut angle α was 90 degrees, 80 degrees, and 70 degrees, but a significant difference was observed at 60 degrees. Furthermore, in the cellophane tape having a cut depth of 2 mm shown in FIG. 5C, no significant difference was observed when the cut angle α was 90 degrees and 80 degrees, but a significant difference was observed when the cut angle was 70 degrees or less.
From the above, it was found that when the cut angle α is 60 degrees or less, the tensile strength is significantly higher than that of 90 degrees.

Next, Table 2 shows the relationship between the ease of cutting and the angle of cut when the pressure-sensitive adhesive tape corresponding to claim 1 is pressed from above. The measurement was carried out by using a commercially available 18 mm wide OPP adhesive tape and a 20 mm wide cellophane tape, and changing the cut angle every 10 degrees. The measurement was carried out by fixing one of the cut adhesive tapes and pressing the top of the adhesive tape near the cut with a nail from above. The test was performed several times at the same angle, and the ease of cutting when pressed was evaluated in four stages: “cut well”, “cut”, “not easily cut”, and “not cut”.
As shown in Table 2, when the cut angle α is 10 degrees, it is considerably harder to cut than 20 degrees. When the cutting angle α is 0 degree, the cutting is almost impossible. From these results, it can be seen that when the cutting angle α is 20 degrees or less, the ease of cutting the adhesive tape decreases as the cutting angle α decreases.

The adhesive tape of Example 1 according to the embodiment of the present invention will be described in detail with reference to FIGS. 6 to 9 and Table 3 (mainly corresponding to claim 1).
The components shown in FIGS. 1 and 2 are denoted by the same reference numerals and description thereof is omitted. FIG. 6 is a plan view of the pressure-sensitive adhesive tape according to Example 1, and FIG.
Table 3 summarizes the configuration of the adhesive tape 6 according to Example 1. The length a of the cut, the distance b in the longitudinal direction of the cut, and the distance c in the short direction of the cut in Table 3 are shown in FIGS. 2 (a) and 2 (b). Note that the present invention is not limited by this illustration.

As shown in FIG. 6, the pressure-sensitive adhesive tape 6 according to Example 1 includes a pressure-sensitive adhesive layer 4 on the back surface of the film base 2 and is provided with a plurality of cuts 7. The notch 7 has a length a (see FIG. 2A, the same applies hereinafter) of 0.8 mm, and a uniform interval b of 3 mm along the longitudinal direction of the adhesive tape 6 in the center of the film base 2 in the short direction. (See FIG. 2 (b), the same applies hereinafter). The film base 2 is a film having a length of 12 mm in the short direction made of OPP. Further, the cut 7 is provided with an angle α of 30 degrees.
The notch 7 is opened substantially perpendicularly to the thickness direction of the adhesive tape 6 and its longitudinal section is linear. The depth is almost equal to the thickness of the film substrate 2 and penetrates the film substrate 2 (not shown). In addition, in FIG. 6, the upper end of the adhesive tape 6 has shown the cut end when it cuts by pushing.

Next, the effect | action of the adhesive tape 6 which concerns on Example 1 is demonstrated.
In order to actually cut the adhesive tape 6, an arbitrary portion in the longitudinal direction of the adhesive tape 6 is fixed by hand or attached to another object and fixed, and the wound body 5 (not shown in FIG. 1). Press the upper part of the adhesive tape 6 peeled off from the reference numeral 5 of a), and the same applies to the center in the short direction, with the tip or fingernail of the finger from above. Then, the pulling force in the longitudinal direction of the adhesive tape 6 acts on the peripheral cut 7 to which the force is applied, and the cut 7 expands. By continuing to apply force, the cut 7 is further expanded and extended toward both side edges of the adhesive tape 6, and the adhesive tape 6 is cut.
In addition, since the plurality of cuts 7 are continuously provided along the longitudinal direction of the film substrate 2 at a constant interval, the adhesive tape 6 is cut even if a force is applied at any position in the longitudinal direction. Also has an effect.
Moreover, when the length of the notch 7 is changed, it has the effect | action that the tensile strength of an adhesive tape and an easiness to cut change.

Next, the effect of the adhesive tape 6 according to Example 1 will be described.
The adhesive tape 6 can be easily cut only by pressing it with a fingertip or a nail.
In the prior art, it was necessary to cut with both hands, but the adhesive tape 6 is particularly excellent in that it is very easy to cut. Further, since the adhesive tape 6 is pressed from the film base 2 side, the adhesive tape 4 can be cut without touching the adhesive layer 4. Therefore, it can be used comfortably and the fingerprint is not left on the adhesive layer 4 and the aesthetic appearance is excellent. Further, it is possible to prevent the adhesive tape from adhering to the finger at the time of cutting or after cutting, or from becoming unusable due to tangling.
In addition, since the adhesive tape 6 is difficult to tear along the longitudinal direction, when the adhesive tape 6 is peeled off from the wound body 5, the adhesive tape 6 may be cut unintentionally and a part of the adhesive tape 6 remains on the wound body 5. Absent.
Moreover, since the notch 7 is near the center of the adhesive tape 6 in the short direction and there is no notch 7 near the cut end, for example, when the cut end of the adhesive tape 6 is peeled off from the wound body 5 Only the side edge portion is not broken or vertically cut from the center. Therefore, 6 pieces of adhesive tape having a desired length can be collected beautifully in appearance.
In addition, since the pressure-sensitive adhesive tape 6 is cut at any position in the longitudinal direction of the pressure-sensitive adhesive tape 6, there is convenience, and the length more than necessary is not cut off.
Further, the tensile strength in the longitudinal direction and the ease of cutting can be adjusted by adjusting the angle α, the length a, and the interval b of the notch 7. Therefore, since the tensile strength and ease of cutting can be adjusted in accordance with the material, purpose of use, and method of use of the film substrate 2, pressure-sensitive adhesive tapes of various specifications can be manufactured, and versatility is high.

The ease of cutting of the pressure-sensitive adhesive tape according to the present embodiment is particularly convenient in the case of cutting the pressure-sensitive adhesive tape used for temporary fixation in addition to the case where a necessary portion is cut from the wound body 5.
Next, an application example of the adhesive tape 6 will be described. As shown in FIG. 7, the adhesive tape 6 fixes a container body 9 used for a lunch box sold at a convenience store or the like and its lid 9a.
Of course, when removing the lid from the container, it is necessary to cut the adhesive tape 6. However, since the lid is larger than the container, the central portion of the adhesive tape 6 that is separated from the container main body 9 and the lid 9a is placed on the fingertip or nail from above. It can be easily cut with one hand. Since the cut piece remains adhered to the container body 9, it does not cling to the hand and does not take time to open. In addition, the tape is not cut unless a strong local force is applied to the tape center instead of the side edge of the tape. It can be said that it is a suitable adhesive tape.

Next, a first modification according to the first embodiment will be described with reference to FIG. FIG. 8 is a plan view of a first modification of the adhesive tape according to the first embodiment.
As shown in FIG. 8, the adhesive tape 6 a according to the first modification of Example 1 is provided with a plurality of cuts 7 a in the film base 2. The film substrate 2 is a film having a length of 12 mm in the short direction made of cellophane. The cut 7a has a length a of 1.0 mm. Since the cellophane film is not easily torn compared to the OPP film, the length a of the cut 7a is set to be longer than the length a of the cut 7.
The angle α of the cut 7a is 30 degrees and −30 degrees. In the cuts 7a, the angles α of 30 degrees and −30 degrees are alternately repeated to form a cut array 8a. Other configurations are the same as those of the adhesive tape 6 of the first embodiment.

Then, the effect | action and effect of the adhesive tape 6a are demonstrated.
In the pressure-sensitive adhesive tape 6a which is the first modification of the first embodiment, the angle α of the cut 7a is alternately changed. Therefore, even when a position slightly deviated from the center toward both ends is pushed, the cut 7a closest to the position is pressed. Expands and the adhesive tape 6a is cut. Therefore, the ease of cutting does not change significantly even when compared with the case of pressing near the center in the short direction. In this regard, in the pressure-sensitive adhesive tape 6 of Example 1 (see FIG. 6), when the pressing position is deviated to the left from the center in the short direction, the cut 7 is more difficult to expand than when deviated to the right. Therefore, there is a possibility that it is difficult to cut. Since there is almost no such possibility in the adhesive tape 6a, it has the effect that it can cut | disconnect stably compared with the adhesive tape 6. FIG.
In addition, the pressure-sensitive adhesive tape 6a according to the first modification of the first embodiment has the same functions and effects as the pressure-sensitive adhesive tape 6 according to the first embodiment. In addition, in FIG. 8, the upper end of the adhesive tape 6a has shown the cut end when it cuts by pushing.

Next, a second modification according to the first embodiment will be described with reference to FIG. FIG. 9 is a plan view of a second modification of the adhesive tape according to the first embodiment.
As shown in FIG. 9, the adhesive tape 6 b according to the second modification of Example 1 is provided with a plurality of cuts 7 b in the film base 2. The film substrate 2 is a film having a length of 12 mm in the short direction made of acetate.
The adhesive tape 6b is a line in which a plurality of (three) cuts 7b are continuous with the film substrate 2 at equal intervals, and then the portions without the cuts 7b are connected at a constant length, and this combination is repeated. A notch array 8b is formed. At this time, the length a and the interval b of the notches 7b are the same as those of the notches 7, and penetrate through the film base 2. The cut angle α is −30 degrees. Further, the length a and the number of the notches 7b and the length of the portion without the notches 7b can be freely changed.
Further, a cut position mark 10 is provided on each side of the three continuous cuts 7b across the central cut 7b. The cut position mark 10 has a triangular shape, but is not limited to this shape. Other configurations are the same as those of the adhesive tape 6 of the first embodiment. In addition, in FIG. 9, the upper end of the adhesive tape 6b has shown the cut end when it cuts by pushing.

And the effect | action and effect of the adhesive tape 6b are demonstrated.
The pressure-sensitive adhesive tape 6b, which is the second modification of the first embodiment, has the effect of being cut by pressing the position where the cut 7b is formed, but is not cut when the portion without the cut 7b is pressed.
However, since the notch position mark 10 is provided on the adhesive tape 6b, cutting is always performed around the notch 7b by pressing this mark. For this reason, it has the effect that the adhesive tape 6b can be cut | disconnected by fixed length.
In addition, the pressure-sensitive adhesive tape 6b according to the second modification of the first embodiment has the same operations and effects as the pressure-sensitive adhesive tape 6 according to the first embodiment.

In addition, the adhesive tape which concerns on Example 1 is not limited to the structure shown in a present Example. For example, the cut length a and the interval b may be values other than those described in Table 3. At this time, the length a may be 0.3 mm or more and 3 mm or less, and 2 mm or less is preferable. Further, the interval b may be at least 1 times the notch length a and at least 2 mm.
The basis for these dimensions has already been described in the section of means for solving the problem.

The pressure-sensitive adhesive tape of Example 2 according to the embodiment of the present invention will be described in detail with reference to FIGS. 10 to 15 and Table 4 (mainly corresponding to claim 2).
The components shown in FIGS. 1 to 9 are denoted by the same reference numerals, and description thereof is omitted.
Hereinafter, the configuration of the pressure-sensitive adhesive tape 11 according to Example 2 will be specifically described with reference to FIG. 10 and Table 4. FIG. 10 is a plan view of the adhesive tape according to the second embodiment. In Table 4, the length a of the notch, the distance b in the longitudinal direction of the notch, the distance c in the short direction of the notch, the distance d in the longitudinal direction of the upper and lower ends of the notches 3b existing in different rows, present in different rows The distance e in the longitudinal direction between the upper end and the upper end of the cut 3b is as shown in FIG. 2B (hereinafter the same in Table 5). Note that the present invention is not limited by this illustration.

As shown in FIG. 10, the adhesive tape 11 according to Example 2 is provided with a plurality of cuts 12 in the film base 2 to form a cut array 13. The cut array 13 is provided in the range of 2/3 of the length from the center in the short direction of the film base 2 to both side edges.
The film substrate 2 is a film having a length of 18 mm in the short direction made of OPP. Further, the notches 12 have a length a of 0.8 mm, and are provided in two rows at an equal interval b of 3 mm along the longitudinal direction of the adhesive tape 11 at the center in the short direction of the film base 2. Each row is separated by 3 mm in the direction away from the center in the short direction of the film substrate 2. That is, the interval c (see FIG. 2B, the same applies hereinafter) is 6 mm. Further, the interval d (see FIG. 2B, the same applies hereinafter) is 3 mm, the interval e (see FIG. 2B, the same applies hereinafter) is 0 mm, and the cut array 13 is a parallel array.
Further, the cutting angle α is 10 degrees in the left column of FIG. 10 and −10 degrees in the right column.
Other configurations are the same as those of the adhesive tape 6 according to the first embodiment. In addition, in FIG. 10, the upper end of the adhesive tape 11 has shown the cut end when it cuts by pushing.

Next, the effect | action of the adhesive tape 11 which concerns on Example 2 is demonstrated.
Since the adhesive tape 11 is provided with two rows of cuts 12, even if the pressing position is deviated from the center in the short direction of the adhesive tape 11 to both ends, there are the cuts 12 near the pressed position. The notch 12 is expanded, and as a result, the adhesive tape 11 is cut. In addition, when the space between the rows of the cut array 13 is pushed from above, the cut 12 is expanded and the adhesive tape 11 is similarly cut. This is the same even if the absolute value of the notch angle α is small.
In addition, the pressure-sensitive adhesive tape 11 according to the second embodiment has the same function as the pressure-sensitive adhesive tape 6 according to the first embodiment.

Furthermore, the effect of the adhesive tape 11 according to Example 2 will be described.
The adhesive tape 11 of Example 2 has a length in the short direction of 18 mm, and the width of the tape is slightly wide. Therefore, there is a possibility that a force from a fingertip or a nail is applied to a position deviating from the vicinity of the center in the short direction.
In the adhesive tape 11, since the notches 12 are arrange | positioned over 2 rows, it can cut | disconnect stably. Further, even when the absolute value of the cut angle α is small, cutting is easy. On the other hand, since the absolute value of the angle α is small, high tensile strength is maintained even though the notches 12 are arranged in two rows.
Since the notch 12 is not disposed in the vicinity of both side edges or the cut end of the adhesive tape 11, only the side edges are broken, and the adhesive tape 11 is attached to the wound body 5 or the hand or vertically cut. There is nothing to do.
In addition, the adhesive tape 11 according to Example 2 has the same effect as the adhesive tape 6 according to Example 1.

Next, a first modification according to the second embodiment will be described with reference to FIG. FIG. 11 is a plan view of a first modification according to the second embodiment.
As shown in FIG. 11, the adhesive tape 11a has the notches 12a having the same length a as the notches 12 of the adhesive tape 11 of Example 2 arranged in two rows. A different part from the configuration of the adhesive tape 11 is that the notch array 13a is formed in a staggered arrangement, and the interval b in the longitudinal direction of the notches 12a is 5 mm.
Other configurations are the same as those of the adhesive tape 11 of the second embodiment. In addition, in FIG. 11, the upper end of the adhesive tape 11a has shown the cut end when it cuts by pushing.

Next, the operation and effect of the adhesive tape 11a will be described.
In the adhesive tape 11a, since the interval b in the longitudinal direction of the notch 12a is larger than the interval b in the notch 12, the number of notches per unit area is reduced as compared with the adhesive tape 11. Therefore, the possibility that the adhesive tape 11a cuts unexpectedly is lower than that of the adhesive tape 11. In addition, this reduction has the effect of contributing to the maintenance of aesthetics.
In addition, it has the same operation and effect as the adhesive tape 11 according to the second embodiment.

Next, a second modification according to the second embodiment will be described with reference to FIG. FIG. 12 is a plan view of a second modification example according to the second embodiment.
As shown in FIG. 12, the adhesive tape 11b is provided with a plurality of cuts 12b along the longitudinal direction of the film substrate 2 to form a cut array 13b. The film base 2 is a film having a length in the short direction of 24 mm made of OPP. The notches 12b are continuously provided at a constant interval b of 6 mm. Furthermore, in the notch arrangement 13b, a total of three rows are provided, one row at the center in the short direction of the film base 2 and 3 mm apart in a direction away from each other vertically from the center row. The notch array 13b forms a parallel array in the relationship between the left and right columns. The notch 12b in the central row is located in the middle of the notches 12b in the left and right rows in the longitudinal direction. Therefore, the notch array 13b forms a staggered array in the relationship between the center column and the left and right columns.
Further, the length of the notch 12b is 0.8 mm, and the notch angle α is 10 degrees in the left column, −10 degrees in the center column, and −10 degrees in the right column. In addition, in FIG. 12, the upper end of the adhesive tape 11b has shown the cut end when it cuts by pushing.

Next, the operation and effect of the adhesive tape 11b will be described.
The length of the adhesive tape 11b in the short direction is wider than that of the adhesive tape 11a, but since the notches 12b are arranged in three rows, the position to be pressed from the vicinity of the center in the short direction is separated. Even in this case, there are many notches 12b distributed around the periphery. Therefore, the cut 12b is expanded and the adhesive tape 11b is cut.
Therefore, the adhesive tape 11b can be stably cut despite its wide width.
In addition, the adhesive tape 11b has the same operations and effects as the adhesive tape 11a according to the first modification of the second embodiment.

Next, a third modification according to the second embodiment will be described with reference to FIG. The specific configuration is as shown in Table 4.
FIG. 13 is a plan view of a third modification according to the second embodiment.
As shown in FIG. 13, the adhesive tape 11 c has a plurality of cuts 12 c provided along the longitudinal direction of the film base 2 to form a cut array 13 c that is a staggered arrangement.
The cut angle α is 10 degrees in all rows. Only this point is different from the adhesive tape 11b, and other configurations are the same as the adhesive tape 11b. In addition, in FIG. 13, the upper end of the adhesive tape 11c has shown the cut end when it cuts by pushing.

Next, the operation and effect of the adhesive tape 11c will be described.
The adhesive tape 11c has the same action as the adhesive tape 11b. However, as shown in FIG. 13, in the case where the cuts 12c that trigger the cutting are in the left column, the cuts 12c in the right column remain at the cut ends (see the cuts 12c surrounded by the symbol X). In such a case, there is a possibility that the adhesive tape 11c is peeled off from the wound body 5 in the longitudinal direction of the adhesive tape from the remaining cut 12c. This occurs when all the cuts in a plurality of rows have the same cut angle α. However, in the usage method in which the adhesive tape 11c is not often peeled off from the wound body 5, this is not a problem, so the direction of the cut 12c may be the same.
Since the adhesive tape 11c has the same direction of the notch 12c, it is easy to form the notch with a blade or the like.
In addition, it has the same effect as the adhesive tape 11b according to the second modification of the second embodiment.

Next, a fourth modification according to the second embodiment will be described with reference to FIG. 14 and Table 4.
FIG. 14 is a plan view of a fourth modification example according to the second embodiment.
As shown in FIG. 14, the adhesive tape 11d is provided with five rows of a plurality of cuts 12d to form a cut array 13d. The notches 12d have a length a of 0.8 mm and are continuously provided with a constant interval b of 5 mm. The length of the adhesive tape 11d in the short direction is 50 mm.
In the notch array 13d, a total of five rows are provided, one at the center and two rows on the left and right sides at a distance of 3 mm and 6 mm away from the center of the film base 2 in the lateral direction. The interval d is 0.55 mm, and the interval e is 1.1 mm. Therefore, the notch array 13d forms a staggered array in all five rows.
Further, the cut angles α are all −45 degrees.

Further, the operation of the adhesive tape 11d will be described with reference to FIG. FIG. 15 is a usage example of the fourth modified example according to the second embodiment, in which the adhesive tape 11d is used for sealing the lid 14a of the cardboard box body 14.
In FIG. 15, the cardboard box body 14 and the lid 14a are fixed to each other by an adhesive tape 11d. When the lid 14a is opened, the surface of the adhesive tape 11d attached along the gap between the cardboard box body 14 and the lid 14a is traced while pushing with a nail. Since the distance d of the adhesive tape 11d is 0.55 mm, any notch 12d exists around the gap. When a force is applied to this notch 12d, it expands.
This expansion extends along the gap between the cardboard box body 14 and the lid 14a, and as a result, the adhesive tape 11d is cut along the short direction. The adhesive tape 11d on the opposite side can be similarly cut. Next, the gap between the lid 14a and the lid 14a is traced while pushing with a nail. Since notches 12d of the adhesive tape 11d are formed with an interval c of 3 mm in all five rows, any of the notches 12d exists around the gap between the lids 14a. When a force is applied to the notch 12d, the adhesive tape 11d is cut in the longitudinal direction along the gap as described above, and the lid 14a can be opened.
In addition, since the adhesive tape 11d has a wide width of 50 mm in the short direction, there is a possibility that when the necessary amount is cut from the wound body 5, it cannot be pushed and cut. This is because when the pushing force is greater than the pulling force in the longitudinal direction at the time of cutting, the extension of the notch 12d is obliquely directed toward the side edge. Therefore, in such a case, it is necessary to cut the necessary amount using a conventional instrument.

Next, the effect of the adhesive tape 11d will be described.
The adhesive tape 11d can be easily opened without using a tool when used for temporarily fixing the lid 14a of the cardboard box body 14 or the like. Opening is only traced with a nail, so it doesn't damage the inside when cutting, unlike a cutter. In addition, since only one cut is necessary for cutting the tape to be pushed and cut, the number of cuts can be reduced, and the cutting requires a local force for the cut near the gap, so that the force applied on the surface In this case, it is difficult to cut with an unintended force applied during transportation.
As a modification of the adhesive tape 11d, the notch and its peripheral part may be colored so that the location of the notch can be seen. Further, in order to ensure that there is a notch in the gap between the lids 14a, the notch array 13d is loosened with a width of about 3 mm from the center of the adhesive tape 1h to the left and right in the short direction (that is, symbol c in FIG. 2B). It may be arranged so as to meander.

In addition, the adhesive tape which concerns on Example 2 is not limited to the structure shown in a present Example. For example, not all α need to satisfy 10 degrees ≦ | α | ≦ 60 degrees, and some α may satisfy 60 degrees <| α | ≦ 90 degrees as long as the present operation and effect can be exhibited. Also good.
Further, the notch intervals b, c, d, and e may be values other than those described in Table 4. At this time, the space | interval b should just be 1 time or more of the notch length a, and at least 2 mm or more. Further, the interval c is 1.5 times or more of the cut length a, and may be at least 3 mm.
The basis for these dimensions has already been described in the section of means for solving the problem.

The adhesive tape of Example 3 will be described in detail with reference to FIGS. 16 to 20 and Table 5 (mainly corresponding to claim 3). Note that the components shown in FIGS. 1 to 15 are denoted by the same reference numerals and description thereof is omitted.
Hereinafter, the configuration of the pressure-sensitive adhesive tape 15 according to Example 3 will be specifically described with reference to FIGS. 16 to 18 and Table 5. FIG. FIG. 16 is a plan view of the adhesive tape according to the third embodiment. 17 and 18 are plan views of cuts related to the adhesive tape of FIG. Note that the present invention is not limited by this illustration.

As shown in FIG. 16, the adhesive tape 15 according to Example 3 includes the adhesive layer 4 on the back surface of the film base 2 and is provided with a plurality of cuts 16.
The film substrate 2 of the adhesive tape 15 is a film having a length of 12 mm in the short direction made of OPP. The notches 16 have a length a of 1.4 mm, and five minute notches 16p having a length of 0.2 mm are continuously formed in a perforated manner at intervals of 0.1 mm (see FIG. 17). The cuts 16 are provided in a line at the center in the short direction of the film base 2 at a uniform interval b of 3 mm along the longitudinal direction of the adhesive tape 15 to form a cut array 17. The angle α of the notch 16 is 30 degrees. Other configurations are the same as those of the adhesive tape 6 according to the first embodiment (see FIG. 6). In addition, in FIG. 16, the upper end of the adhesive tape 15 has shown the cut end when it cuts by pushing.

Next, the effect | action of the adhesive tape 15 which concerns on Example 3 is demonstrated.
When the adhesive tape 15 is pressed near the center in the short direction from above, the 0.1 mm wide film base 2 in the cut 16 is cut and the fine cuts 16p having a length of 0.2 mm are connected to each other.
The connected notches 16a are shown in FIG. The length a of the cut 16a is 1.4 mm.
Further, each minute notch 16p tends to be more difficult to expand with respect to the tensile force of the adhesive tape 15 in the longitudinal direction.
In addition, the action of the pressure-sensitive adhesive tape 15 provided with the notches 16a is the same as that of the pressure-sensitive adhesive tape 6 of the first embodiment.

Next, the effect of the adhesive tape 15 according to the third embodiment will be described.
As shown in FIGS. 17 and 18, the minute notches 16p constituting the notches 16 are easily connected by a pressing force from above, and become the notches 16a. Since the minute notches 16p tend to be more difficult to expand, the adhesive tape 15 has a higher tensile strength. That is, the perforated cut 16 can have a higher tensile strength than a cut that is not perforated like the cut 7 (see FIG. 6) of the adhesive tape 6 according to the first embodiment. Therefore, it is possible to maintain a sufficient tensile strength even if the cut angle α is increased.
In addition, the effect of the adhesive tape 15 provided with the notches 16 is the same as that of the adhesive tape 6 of the first embodiment.

Next, the notch according to the first modification of the notch 16 will be described with reference to FIG. FIG. 19 is a plan view schematically showing the notch of the first modification of the third embodiment, but it is not necessarily the same as this figure.
As shown in FIG. 19, the notches 16b according to the first modified example are such that the minute notches 16q are arranged in parallel in two rows with an interval of 0.1 mm.
Next, the operation of the cut 16b will be described. The notches 16b are more easily expanded than the notches 16 because the minute notches 16q are connected between two rows due to the force from above. However, since the length of the minute notches 16q constituting the notches 16b is as short as 16p, it is difficult to expand against the pulling force. Therefore, the tensile strength is not greatly affected.
The number of columns needs to be determined in consideration of the unintended force and the ease of disconnection from the wound body 5 as the number of columns increases.

Next, the notch according to the second modification of the notch 16 will be described with reference to FIG. FIG. 20 is a plan view schematically showing a cut in the second modification of the third embodiment, but it does not necessarily have to be as shown in this figure.
As shown in FIG. 20, the cut 16c according to the second modified example is a continuous series of small irregular cuts 16r of 0.2 mm with an interval of 0.1 mm. The notches 16 c are formed by arranging five sharp needles having a diameter of 0.3 mm so that the angle with respect to the longitudinal direction of the film substrate 2 is 30 degrees and inserting these into the film substrate 2.
The other configuration is the same as that of the notch 16, and the operation is the same as that of the notch 16.
As for the effect, the notch 16c is formed from a minute irregular-shaped notch 16r, so that there is a variation in the ease of cutting. Is a big advantage.
In addition, the effect of the notch 16 c is the same as that of the notch 16.

The pressure-sensitive adhesive tape of Example 4 according to the embodiment of the present invention will be described in detail with reference to FIGS. 21 to 30 and Table 5 (mainly corresponding to claim 4).
Note that the components shown in FIGS. 1 to 20 are denoted by the same reference numerals and description thereof is omitted.
The configuration of the adhesive tape 18 according to Example 4 will be specifically described below with reference to FIG. 21 and Table 4. FIG. 21 is a plan view of the adhesive tape according to the fourth embodiment. Note that the present invention is not limited by this illustration.

As shown in FIG. 21, the adhesive tape 18 according to Example 4 is provided with a plurality of cuts 19 in the film base 2. The film base 2 of the present embodiment is a film having a length of 9 mm in the short direction made of OPP. The film base 2 is provided with a portion not provided with the adhesive layer 4 (indicated by hatching in the figure, the same in the following figures). This portion is within a range of about 2/3 from the center in the short direction of the adhesive tape 18 toward both side edges.
The notches 19 have a length a of 2 mm, and are provided in a line at the center of the film base 2 in the short direction at an equal interval of 2 mm along the longitudinal direction of the adhesive tape 18 to form a notch array 20. . The angle α of the cut 19 is 60 degrees. In addition, in FIG. 21, the upper end of the adhesive tape 18 has shown the cut end when it cuts by pushing.

Next, the effect | action of the adhesive tape 18 is demonstrated using FIG. FIG. 22 is a usage example of the adhesive tape according to the fourth embodiment.
As shown in FIG. 22, the adhesive tape 18 binds the opening of the bag 21. The end portions of the adhesive tape 18 adhere the adhesive tapes 18 so as not to peel off without adhering to the bag 21. However, even in the adhesive tape 18 adhered to the bag 21, the hatched portion not provided with the adhesive layer 4 is not adhered to the bag 21.
As a specific opening method, when the adhesive tape surface near the boundary between the adhesive tape 18 and the bag 21 is pushed with a nail of the thumb from above while pulling the bound portion of the adhesive tape 18 and the bag 21, the cut 19 is not adhered. Expand. Since the side edge portion of the adhesive tape 18 adheres to the binding portion of the bag 21 that is folded several times, the adhesive tape 18 is pulled in the longitudinal direction when the binding portion is handled so as to be widened. . Accordingly, the cut 19 extends toward the side edge, and the adhesive tape 18 is cut.
The operation when the necessary amount of the adhesive tape 18 is cut from the wound body 5 is the same as that of the adhesive tape 6 according to the first embodiment.

Next, the effect of the adhesive tape 18 will be described.
The adhesive tape 18 can be easily cut when it is used as a binding tape. Conventional adhesive tape for bundling is almost impossible to cut by hand, and because of its strong adhesive force, it was almost impossible to peel it off. It will be solved. Further, a strong force is applied to the adhesive tape 18 in the longitudinal direction at the time of binding, but the tensile strength can be adjusted by appropriately setting the length a of the cut 19 and the cut angle α. Therefore, it is difficult to cut carelessly during binding, and binding is unlikely to fail.
In addition, it has the same effect as the adhesive tape 6 according to the first embodiment.

Next, a first modification and a second modification according to the fourth embodiment will be described with reference to FIGS. FIG. 23 is a use state diagram of the first modification example according to the fourth embodiment, and FIG. 24 is a use condition diagram of the second modification example according to the fourth embodiment.
As shown in FIG. 23, the pressure-sensitive adhesive tape 18a according to the first modification of the present embodiment repeatedly provides a portion not including the pressure-sensitive adhesive layer 4 having a desired length in the longitudinal direction. The length of the portion not provided with the adhesive layer 4 may be determined depending on the application. Further, in this modification, a portion not provided with the adhesive layer 4 is formed in the entire short direction, but a portion having no adhesive layer 4 in a part in the short direction as in Example 4 may be used. Good. Also in this modification, the film base 2 is provided with a plurality of cuts 19a. The film base 2 of the present embodiment is a film having a length in the short direction of 18 mm made of OPP. The cuts 19a have a length a of 0.8 mm, and are provided in a line at the center in the short direction of the film base 2 at a uniform interval of 3 mm along the longitudinal direction of the adhesive tape 18a. Form. The angle α of the cut 19a is 30 degrees.
In this modification, the portion not provided with the adhesive layer 4 is in the range of 6 cm in length along the longitudinal direction. In addition, the presence or absence of the adhesion layer 4 can be clarified by coloring the transparent film substrate 2 and the adhesion layer 4.

  And as shown in FIG. 24, the adhesive tape 18b which concerns on the 2nd modification of a present Example is provided with the fixed length part without the notch 19b. The portion without the notch 19b includes the adhesive layer 4. Other configurations are the same as those of the adhesive tape 18a. In addition, about the part which is not provided with the adhesion layer 4, although it forms in the whole transversal direction similarly to the modification 1, you may make it equip in a part of transversal direction.

Next, the operation of the adhesive tape 18a and the adhesive tape 18b will be described.
As shown in FIG. 23, in the adhesive tape 18a, the part which does not have the adhesion layer 4 is located between the binding material 21a and the binding material 21a. In such a case, the cut 19a in this portion is not adhered to the bundle 21a, so by pressing the center of the tape with a fingertip or nail, the nearby cut 19a expands and extends to the side end of the adhesive tape 18a. The adhesive tape 18a is cut. When the bound material 21a changes flexibly, even if the center of the tape is pushed, the bound material 21a is deformed, and the force for pulling the tape does not act, so that it cannot be cut. In this case, the index finger and the middle finger can be cut by placing the index finger and the middle finger between the adhesive tape 18a and the bundle 21a and pressing the adhesive tape 18a with the tip of the thumb or the nail while pulling the adhesive tape 18a forward.
Then, as shown in FIG. 24, in the adhesive tape 18b, the part which does not have the adhesion layer 4 is located in the binding material 21a. For example, in the case where the bundle 21a does not have flexibility, even if the cut 19b is pushed from above, the bundle 21a becomes a support without being recessed and the cut 19b does not expand, so the adhesive tape 18b is not cut. However, in the case where the bundle 21a is easily changed in shape like a pack containing air together with food such as a wiener bag, it is possible to insert an index finger and a middle finger between the adhesive tape 18b and the bundle 21a. It is. In this way, when the center of the tape is pushed with the tip of the thumb, the cut 19b expands and the adhesive tape 18b is cut. Thereafter, the binding can be released by grasping and peeling off the cut end without the adhesive layer 4.

Further, effects of the adhesive tape 18a and the adhesive tape 18b will be described.
Both of the adhesive tape 18a and the adhesive tape 18b are suitable for bundling of a pack or the like having flexibility that contains air together with food like a Wiener bag. In this case, regardless of the position of the portion not provided with the adhesive layer 4, it can be easily cut with a finger without using an instrument. In particular, as shown in FIG. 24, when the portion of the adhesive tape 18b that does not include the adhesive layer 4 is in close contact with the bundle 21a, the notch 19b is not pressed by the air-pack without the adhesive layer 4. Therefore, even when pressure is applied to the adhesive tape 18b during transportation or the like, there is little possibility that a local force is applied to the cut 19b of the adhesive tape 18b simply by deforming the pack itself by a certain amount, and the gap of the cut 19b is widened. The possibility is low. For this reason, even if a strong force is applied during transportation or the like, it is unlikely to break.
The pressure-sensitive adhesive tape 18 a having a cut also in the pressure-sensitive adhesive layer 4 can be cut only by pressing even when a necessary length is cut from the wound body 5. However, a tool is required for cutting the adhesive tape 18b.

Next, a third modification and a fourth modification according to the fourth embodiment will be described with reference to FIGS. FIG. 25 is a plan view of a third modification example according to the fourth embodiment, and FIG. 26 is a use state diagram of the fourth modification example according to the fourth embodiment.
As shown in FIG. 25, the adhesive tape 18 c according to the third modification of the present embodiment is provided with a plurality of cuts 19 c in the film base 2. The adhesive tape 18c of the present example has the same configuration as the adhesive tape 11 according to Example 2 (see FIG. 10), except that a portion not provided with the adhesive layer 4 is formed. The part not provided with the adhesive layer 4 is a part that occupies from the center in the short direction of the adhesive tape 18c to one side edge.
Furthermore, as shown in FIG. 26, the adhesive tape 18d according to the fourth modification of the present embodiment is one in which the notch on the side where the adhesive layer 4 is provided is omitted from the notch 19c of the adhesive tape 18c. There is only a notch 19d. Other configurations are the same as those of the adhesive tape 18c. In FIG. 26, the bundle 21a is bundled using the adhesive tape 18d.

Next, the operation of the adhesive tape 18c and the adhesive tape 18d will be described.
The action of the adhesive tape 18c is the same as that of the adhesive tape 11. However, when the adhesive tape 18c is used for temporary fixing, the adhesive tape 18c is pulled and the notch 19c provided in the portion not provided with the adhesive layer 4 is pressed, thereby the notch. 19c is easily extended to a side edge portion that does not include the adhesive layer 4. If the part which does not have the adhesion layer 4 is grabbed and the adhesion part is peeled off, the cut 19c expands and the adhesive tape 18c can be cut.
Since the adhesive tape 18d has a portion that does not include the adhesive layer 4 in any part in the longitudinal direction, the adhesive tape 18d is cut at an arbitrary portion as long as the index finger and the middle finger can be inserted between the adhesive tape 18d and the bundle 21a. For cutting, if the index finger and the middle finger are inserted and the vicinity of the notch 19d is pressed with the tip of the thumb from above, the notch 19d in the vicinity is expanded, and the portion of the adhesive tape 18d that does not have the adhesive layer 4 is cut. In order to cut | disconnect the adhesive tape 18d adhering to the binding material 21a, it can cut | disconnect, if the part which does not have the adhesion layer 4 is grasped and peeled similarly to the adhesive tape 18c.

Next, effects of the adhesive tape 18c and the adhesive tape 18d will be described.
The cut 19c of the part having the adhesive layer 4 in the adhesive tape 18c cannot be used for cutting the adhesive tape 18c once it is adhered to a bundle or the like. However, when the necessary length is cut from the wound body 5, it can be cut by pressing because it is not adhered to a bundle or the like. However, since the adhesive tape 18d has the cut 19d only on one side, it is better to use a tool when cutting the required length from the wound body 5.
The adhesive tape 18c and the adhesive tape 18d are excellent in that they can be easily cut at a portion located between the bundles even if the bundles do not change in shape. Moreover, since it has a part which is not equipped with the adhesion layer 4 in any part of a longitudinal direction, if an index finger and a middle finger can be put between the adhesive tape 18d and the binding thing 21a, it can cut | disconnect in arbitrary parts.
Furthermore, since the part which does not have the adhesion layer 4 is parallel to the longitudinal direction of the adhesion tapes 18c and 18d, the application of the adhesion layer 4 is easy.
In addition, it has the same operation and effect as the adhesive tape 11 according to the second embodiment.

Next, a fifth modification of the fourth embodiment will be described with reference to FIG.
FIG. 27 is a plan view of a fifth modification example according to the fourth embodiment.
As shown in FIG. 27, the adhesive tape 18e according to the fifth modification of the present embodiment is provided with a plurality of cuts 19e in the film base 2.
The film base 2 of the present embodiment is a film having a length in the short direction of 18 mm made of OPP. The notches 19e have a length a of 0.8 mm, and are provided in two rows at the center in the short direction of the film substrate 2 with an equal interval b of 3 mm along the longitudinal direction of the adhesive tape 18e. Each row is separated by 3 mm in the direction away from the center in the short direction of the film base 2 to form a cut array 20e. The angle α of the cut 19e is 30 degrees on the left side and -30 degrees on the right side.
Moreover, the part which does not have the adhesion layer 4 exists in the range of length 1cm along the longitudinal direction of the adhesive tape 18e. In addition, in FIG. 27, the upper end of the adhesive tape 18e has shown the cut end when it cuts by pushing.

Next, the operation and effect of the adhesive tape 18e will be described with reference to FIG.
FIG. 28 is a diagram illustrating a usage state of the fifth modification example of the fourth embodiment.
As shown in FIG. 28, the adhesive tape 18e is used to fix the box body 22 and the lid 22a, and a portion that does not have the adhesive layer 4 is positioned in the opening portion of the lid 22a. When opening the lid 22a, when the nail is pressed between the box body 22 and the lid 22a from above the adhesive tape 18e, the lid 22a is pushed into the box body 22 by a local force, and the adhesive tape 18e and the lid A space is created between 22a. By being pushed in, a force is applied to the adhesive tape 18e, the nearby cut 19e expands and extends to the side edge of the adhesive tape 18e, and the adhesive tape 18e is cut.
Furthermore, since the adhesive tape 18e is cut only by pressing, the lid 22a can be opened very easily. When a non-local force is applied to the entire lid 22a, the lid 22a is slightly recessed inside, but the notch 19e does not expand to that extent, and therefore the lid 22a is not easily opened by an unintended force.

Next, a sixth modification of the fourth embodiment will be described with reference to FIG.
FIG. 29 is a plan view of a sixth modified example according to the fourth embodiment.
As shown in FIG. 29, the adhesive tape 18f according to the sixth modification of the present embodiment is provided with a plurality of cuts 19f in the film base 2.
The adhesive tape 18f of the present example has the same configuration as the adhesive tape 11b (see FIG. 12) according to the second modification example of Example 2 except that the adhesive tape 18f includes a portion that does not have the adhesive layer 4.
The portion not having the adhesive layer 4 is 2 cm in length along the longitudinal direction, and is within a range of 5/6 from one side in the lateral direction.

Next, the operation and effect of the adhesive tape 18f will be described.
Since the adhesive tape 18f is provided with the adhesive layer 4 at portions other than the diagonal line on the left side of the adhesive tape 18f, if the adhesive tape 18f is attached to a bundle, the cut 19f is not expanded only by pressing from above, and the adhesive tape 18f is not cut. However, for example, when the adhesive tape 18f is used for the purpose of fixing the lid 22a (see FIG. 28), if the lid 22a is pressed firmly, the lid 22a is pushed into the box 22 and the adhesive layer 4 is peeled off from the lid 22a. The adhesive tape 18f is cut in the same manner as the adhesive tape 18e.
The adhesive tape 18f is used for temporary fixing of the lid 22a and the like similarly to the adhesive tape 18e. However, since the adhesive layer 4 is partly provided unlike the adhesive tape 18e, the lid 22a and the box are stronger than the adhesive tape 18e. It is necessary to push between the main bodies 22 with a nail. However, since the adhesive tape 18e is fixed stronger than the adhesive tape 18e, the possibility that the adhesive tape 18f is cut during transportation is reduced. In addition, what is necessary is just to change suitably the area of the part which does not have the adhesion layer 4, so that it may be suitable for actual utilization, and other than FIG.
In addition, it has the same operation and effect as the adhesive tape 11b according to the second modification of the second embodiment.

Next, a seventh modification of the fourth embodiment will be described with reference to FIG.
FIG. 30 is a plan view of a seventh modification example according to the fourth embodiment.
As shown in FIG. 30, the adhesive tape 18g which concerns on the 7th modification of a present Example is provided with the some notch 19g in the film base material 2. As shown in FIG.
The pressure-sensitive adhesive tape 18g of the present example has the same configuration as the pressure-sensitive adhesive tape 6b (see FIG. 9) according to the second modification example of Example 1 except that a portion not having the pressure-sensitive adhesive layer 4 is provided.
The portion not having the adhesive layer 4 is within a range of 4 cm in length along the longitudinal direction of the adhesive tape 18g, centering on the portion having the cut 19g. In addition, in FIG. 30, the upper end of the adhesive tape 18g has shown the cut end when it cuts by pushing.

Next, the operation and effect of the adhesive tape 18g will be described.
When the adhesive tape 18g cuts the required length from the wound body 5, the cut 19g is expanded by pressing the portion indicated by the cut position mark 10 with a fingertip or a nail, and is cut as a result.
Since the adhesive tape 18g can be cut only at the cut position mark 10 previously indicated by a triangle, the length of the adhesive tape is constant and there is no waste. Since the cut-off terminal does not have the adhesive layer 4, even if it is attached to an object while holding both terminals, it does not stick to the finger and is easy to apply. Also, since no fingerprints remain, the beauty can be maintained. Further, when the adhesive tape 18g is peeled off, it is easy to peel off by grasping this portion. Therefore, the adhesive tape 18g can be used for temporarily fixing parts of industrial products such as during transportation.
In addition, it has the same operation and effect as the adhesive tape 6b according to the second modification of the first embodiment.

For manufacturing device of the adhesive tape cut by pressing of Example 5 according to the embodiment of the present invention, that describes in detail with reference to FIGS. 31 to 33.
The components shown in FIGS. 1 to 30 are denoted by the same reference numerals, and description thereof is omitted. FIG. 31 is an external perspective view of the pressure-sensitive adhesive tape manufacturing tool according to Example 5, and FIG. FIG. 33 is a side view of a modified example of the pressure-sensitive adhesive tape manufacturing tool of Example 5.
The configuration of the pressure-sensitive adhesive tape manufacturing tool 23 according to Example 5 will be specifically described below. Note that the present invention is not limited by this illustration.

As shown in FIG. 31, the adhesive tape manufacturing instrument 23 according to the fifth embodiment includes a rotatable cylinder 24 having protrusions 24 a in which sharp thin needles are linearly arranged on a circumferential surface, and a central axis of the cylinder 24. And a support 25 that supports 24b. The support 25 includes a support shaft 25a on the opposite side of the central shaft 24b. A spring 26 is attached to the support 25 to press the cylinder 24 against the adhesive tape 27. In addition, the protrusion 24a determines the height and the position of the cylinder 24 so as to penetrate only one film base material 2.
In FIG. 31, the circumferential surface of the cylinder 24 is pressed against the wound body 5 of the adhesive tape 27 by the spring 26, and the cut 28 is formed as the adhesive tape 27 is peeled off from the wound body 5. Is shown.

Next, the operation of the adhesive tape manufacturing tool 23 will be described.
The circumferential surface of the cylinder 24 having the protrusions 24 a is pressed against the adhesive tape 27 by the spring 26, so that the protrusions 24 a are cut into only the film base 2 of the outermost layer of the adhesive tape 27. The protrusion 24a also serves as a spike. As the adhesive tape 27 is peeled off from the wound body 5, the cylinder 24 is rotated to form a further cut 28. Although the thickness of the wound body 5 decreases when the adhesive tape 27 is peeled off, the circumferential surface of the cylinder 24 is always pressed against the adhesive tape 27 by the support body 25 pressed by the spring 26.
Moreover, not only the notch 28 but the notch 16c (refer FIG. 20) is formed with the sharp needle | hook which comprises the processus | protrusion 24a. If the interval between the needles is further reduced, the notch 7 (see FIG. 6) of the first embodiment is also formed. Or if the processus | protrusion 24a is made into multiple rows | lines, the notch arrangement | sequence 13 (refer FIG. 10) of Example 2 will be formed. FIG. 32 shows a notch 29 formed when the interval between the needles is narrowed.

  Furthermore, the effect of the adhesive tape manufacturing tool 23 will be described. The adhesive tape manufacturing instrument 23 may be used in the process of manufacturing the film substrate 2 in addition to being used by being attached to a tape holder because of its simple structure. When attached to a tape holder, a notch can be made in a commercially available adhesive tape.

The adhesive tape manufacturing tool 23 is not limited to the structure shown in FIG. For example, as shown in FIG. 33, a modification of the fifth embodiment is also conceivable. The adhesive tape manufacturing tool 23 a includes rotating bodies 30 and 31 before and after the cylinder 24, and is attached to the tape holder 32 together with the wound body 5. At this time, the positions of the rotating bodies 30 and 31 with respect to the cylinder 24 are adjusted so that the film base 2 is always in contact with the circumferential surface of the cylinder 24 on the path of the adhesive tape 27 (A in the drawing). The rotating shaft 24 b of the cylinder 24 is fixed to the tape holder 32.
In such an adhesive tape manufacturing tool 23 a, the adhesive tape 27 is pressed against the circumferential surface of the cylinder 24 by the force when the adhesive tape 27 is pulled out from the tape holder 32. This is the same even when the wound body 5 becomes thin (the path of the adhesive tape 27, B in the figure).
Other operations are the same as those in the fifth embodiment. In this modification, a simpler structure than that of the fifth embodiment can be obtained.
