Description

  The present invention relates to an adhesive tape that can be easily cut, and more particularly, to an adhesive tape that can be suitably used in a tape applicator that applies a continuously supplied adhesive tape with a predetermined length.

  Conventionally, adhesive tape has been widely used for sealing and packaging of various articles such as stationery and office supplies. In particular, in recent years, as a package for lunch boxes and prepared dishes sold at convenience stores and supermarkets (hereinafter referred to as “lunch boxes”), instead of conventional wrap packaging, packaging with only adhesive tape is often used. Yes. And as such packaging of lunch boxes, the container main body which accommodated the content is covered with a cover body, and the packaging which integrates a container main body and a cover body with an adhesive tape is performed.

  In such packaging, there is a problem that the adhesive tape that holds the lid of the lunch box is difficult to peel off and the lid is difficult to open. Therefore, in recent years, an adhesive tape that is easily peeled off and devised has also been proposed. For example, in Patent Document 1 (utility model registration No. 3105681), a portion where the paste is attached to the cellophane tape and a portion where the adhesive is not attached Cellophane tape has been proposed in which the cellophane tape is easy to peel off after use.

  Moreover, patent document 2 (Unexamined-Japanese-Patent No. 2012-2111247) is proposed about the adhesive tape for food container sealing. This document provides an adhesive tape that does not peel off in a refrigerated showcase, does not remain glued after heating in a microwave oven, and does not break when the tape is cut even if the tape is notched. ing. And in this document 2, as shown in FIG. 5, it is also proposed to make a cut in the adhesive tape so that it can be easily broken by hand. The direction of the cut may be the width direction or the length direction, but preferably the cut is made in the length direction, the cut may be placed near the center, but preferably the cut is made on both sides of the adhesive tape. It is described.

  Furthermore, an adhesive tape and an adhesive sheet that can be cut by hand without a cutting tool and have a straight line are also disclosed in Patent Document 3 (Utility Model Registration No. 3070013). In this document, as shown in FIG. 6, a perforated pressure-sensitive adhesive tape characterized in that a perforation for cutting is provided in the pressure-sensitive adhesive tape has been proposed. And it is also disclosed that the tape is cut so that perforations are formed at both ends of the tape so that the tape is easy to cut and the cut edge is not disturbed.

  There has also been proposed a machine for attaching an adhesive tape to a lunch box made of a square plastic molded product in plan view. For example, in Patent Document 4 (Japanese Patent Application Laid-Open No. 2012-206740), a tape piece cut at a predetermined length is applied to the outer edge of a container with a lid attached to the container body, and the lid and the container body are fixed. A sticking device for sticking a leading end portion of an adhesive tape drawn from a tape roll to a lid of a container and sticking a terminal portion of a cut tape piece to a container body, and a lower surface side of the sticking arm The adhering part that adsorbs the adhesive tape from the non-adhesive surface side at the tip of the adhering arm and the adhering tape to the adhering tape upstream of the adhering path from the adsorbing part. A tape applicator provided with supporting means for holding on the lower surface side of the tape is disclosed.

Utility Model Registration No. 3105681 JP 2012-2111247 A Utility Model Registration No. 3070013 JP 2012-206740 A

  As described above, in order to cut the tape easily by hand without using scissors or the like, various proposals have been made to provide a cut or perforation on the tape. However, all focus only on making the tape easy to cut, and problems in actual use are not considered. In other words, when sticking adhesive tape to containers such as lunch boxes and prepared dishes, or other items and containers, if the sticking work is done manually, the force can be adjusted finely, so cut at unintended parts. There is no end to it.

  However, when affixing adhesive tape with the tape applicator as described above, the adhesive tape that has been processed so that it can be easily cut as before will be cut at unintended parts during operation of the tape applicator. As a result, there is a problem of causing poor sticking. Further, as in the case of the adhesive tape shown in Patent Document 3, when the perforated cutout is formed so as to be hooked on both ends of the tape, the tape is drawn out in the left-right direction (the width direction of the tape). If it slips out, it will be cut when it is pulled out, and the work will have to be interrupted. In addition, if the direction of the cut line to be simply put in the adhesive tape is the width direction, the tape will be easier to cut, but the tensile strength will be weak and it will be difficult to apply using the tape applicator. there were. That is, it has been difficult to simultaneously achieve the pursuit of cutting and the application using the tape application device.

  Therefore, in the present invention, even when a tape is applied using a tape applying device, the adhesive tape is not cut at an unintended part, and can be stably applied. The first object is to provide an adhesive tape that can be easily cut by hand.

In addition, as described in Patent Document 3, in the case where perforations are formed on both end portions of the tape, the side surface of the adhesive tape is wound in a roll shape, Unevenness due to notches sometimes appeared. The unevenness on the side surface of the roll tape interferes with a tape dispenser or the like when the adhesive tape is pulled out, preventing smooth tape pull-out.
Therefore, in the present invention, it is a second object to provide an adhesive tape that can be easily cut by hand, but does not appear uneven on the side surface even when it is rolled.

Furthermore, a lunch box, a package of prepared dishes, or other articles, and an adhesive tape affixed to the package are parts that the user visually observes at least when opening the container. That is, in the packaging container, the pressure-sensitive adhesive tape is a portion that is easily visually recognized and recognized, and has a high advertising effect.
Accordingly, a third object of the present invention is to provide a pressure-sensitive adhesive tape that secures an advertising space that can exhibit a sufficient advertising effect while being easily cut by hand.

  In order to solve at least one of the above problems, in the present invention, an adhesive tape having improved tensile strength is formed by forming a long cut in the width direction of the tape and not forming a cut at both end portions of the tape. provide.

  That is, in the present invention, an adhesive tape comprising a base material having a predetermined width and an adhesive layer provided on at least one surface of the base material, the base material having a long portion in the width direction. A plurality of cuts are formed side by side in the length direction of the substrate, and the cuts are formed at least 1 mm away from both side ends along the length direction of the substrate, and Provided is an adhesive tape having no cut at both end portions along the length direction of the substrate.

  Such an adhesive tape is composed of a base material having a predetermined width and an adhesive layer provided on at least one surface of the base material, and can be accompanied by various decorations on any surface of the base material. It is.

  The base material constituting the adhesive tape can be formed using various materials that have been used for adhesive tapes in the past, for example, synthetic resin materials such as cellophane, polyester, polypropylene, polystyrene, orient polypropylene, Paper or cloth can also be used. Such a substrate can be formed in a band shape, a tape shape, or a sheet shape, and is formed into a shape having at least a certain width and length. In particular, when used in a food packaging container and applied with a tape applicator, it is desirable to use orient polypropylene to increase the tensile strength.

  An adhesive layer is provided on at least one surface of the substrate. The material for forming such an adhesive layer can be used without any particular problem as long as it is a material used for conventional adhesive tapes. However, it should be appropriately selected depending on the application, such as whether it is used for food packaging containers or industrial applications. In the pressure-sensitive adhesive tape according to the present invention, the pressure-sensitive adhesive layer may be provided on at least one surface of the base material, and the pressure-sensitive adhesive layer is formed on one surface or both surfaces of the base material. good. In addition, the adhesive layer may be provided only on at least one of the surfaces of the base material, or may be provided in any region, or a band-like adhesive layer may be provided at a predetermined interval.

  And in the adhesive tape which concerns on this invention, in order to make it easy to cut | disconnect, the several cut | interruption which has a long part in the width direction is formed in the said base material at least. Such a cut need only have a long portion in the width direction, and may have a long cut portion in the length direction. Alternatively, it may be a rhombus or oblong hole so that the direction of the diagonal line or the major axis is in the width direction. That is, the cut line in the present invention includes not only a shape in which a cut is made in a linear shape but also one formed as a hole having a certain area.

  Such cuts are formed side by side in the length direction of the substrate, and may be formed regularly at regular intervals or at arbitrary intervals without regularity. Further, even when the gaps are formed at a constant interval, all the cuts can be arranged at the same interval, and the plurality of cuts can be arranged at different intervals.

  And although the said cut | interruption needs to be formed at least in a base material, while penetrating a base material, you may form so that an adhesion layer may also penetrate. In particular, when the adhesive layer is formed of a material having a high tensile strength and / or a thickness, specifically, when it is difficult to cut by hand, a cut may be formed in the adhesive layer. is necessary. In this case, it is desirable that the cut is formed so as to penetrate the base material and penetrate the adhesive layer as it is.

  As described above, by forming a plurality of long cuts in the width direction with respect to at least the base material, the tensile strength of the base material becomes weak at the position where the cuts are present, and the cuts are made. As a trigger, the base material and further the adhesive tape can be easily cut.

  A plurality of the cuts can be arranged in the width direction of the substrate as will be described later. Even in this case, the cut is formed in a region at least 1 mm away from both end portions along the length direction of the base material, and there is a cut at both side end portions along the length direction of the base material. It is necessary not to do. Even if it is not pulled straight in the length direction of the adhesive tape, that is, when it is pulled slightly diagonally, because there is no cut at both end portions along the length direction of the substrate. Since there is no cut at both end portions along the length direction, it is possible to eliminate the problem of simple cutting depending on the pulling direction.

  In addition, the cut is formed in a region 1 mm or more away from both side end portions along the length direction of the base material, and therefore, the range of 1 mm or more from both side end portions along the length direction of the base material pulls out the adhesive tape. It can function as a reinforcing part at the time, thereby avoiding unintentional cutting of the adhesive tape. The width of the reinforcing portion, that is, the width of the region where there is no cut at both end portions along the length direction of the base material is 1 mm or more, preferably 1.5 mm or more. It can be appropriately adjusted in consideration of the material and thickness of the layer, the shape of the cut, and the like.

  And when it is generally used for packaging food and used to fix the lid to the container body, in view of the fact that an adhesive tape having a width of about 19 mm is often used, the present invention The pressure-sensitive adhesive tape has a width of about 19 mm, the base material is a sheet made of orient polypropylene, the length of the cuts is 4 mm or less, and the interval between the cuts arranged in the length direction of the base material is 5 mm or more. It is desirable that By configuring in this way, it is possible to eliminate the problem that the adhesive tape is unintentionally cut in the process of drawing, sticking, and cutting the adhesive tape using the tape applying device.

  In addition, a plurality of the cuts are arranged in the length direction of the base material, but the plurality of cut lines arranged in the length direction of the base material are formed in one row, and in the width direction of the base material. Two rows can be formed side by side. When two rows of cuts are formed in this way, it is desirable to secure an area portion with a width of 6 mm or more between which the cuts do not exist. This is because the advertisement effect can be enhanced by displaying the company name and other advertisements in the area where there is no break. In addition, by securing a region having a width of 6 mm or more between the lines of cuts in this way, it is possible to prevent twisting when pulling out the pressure-sensitive adhesive tape, and to further prevent the pressure-sensitive adhesive tape from Even when the surface (upper surface) side is sucked and pulled out, the pressure-sensitive adhesive tape can be reliably sucked. Note that this area portion can be used as an advertisement area for displaying an advertisement as described above, and can also be used as a decoration area for decoration other than the advertisement.

  When two or more rows of cuts arranged in the length direction of the base material are formed in the width direction of the base material, the cuts in each row are alternated in the length direction of the base material. It is also desirable to form it so that it exists. It is also desirable to arrange the two rows of cuts arranged in the width direction of the base material in a staggered manner. This is because the tensile strength in the length direction of the base material can be secured while being cut at an arbitrary place.

  The pressure-sensitive adhesive tape according to the present invention is not necessarily used only for securing the container body and the container lid, but can be used in various other applications as a stationery such as closing an envelope. In particular, although the pressure-sensitive adhesive tape according to the present invention is easy to cut in the width direction, it is difficult to cut or tear in the length direction of the pressure-sensitive adhesive tape. Therefore, it can be effectively used as an adhesive tape that needs to be cut in the width direction.

  And the present invention is not necessarily carried out only in the adhesive tape, it is also included in the idea of the present invention to carry out in a simple tape, that is, a tape made of a base material having no adhesive layer, The present invention is within the technically equivalent range.

  According to the pressure-sensitive adhesive tape of the present invention configured as described above, since the base material constituting the pressure-sensitive adhesive tape is formed with a plurality of cuts having long portions in the width direction, the pressure-sensitive adhesive tape It can be easily cut by hand in the width direction. Moreover, since this cut | interruption is formed side by side in the length direction of the said base material, it can cut | disconnect easily in arbitrary places.

  Further, the cut line is formed at least in a region separated by 1 mm or more from both side end portions along the length direction of the base material, and there is no cut at both side end portions along the length direction of the base material. Therefore, when pulling out with the tape applicator, it is possible to prevent the unintended portion from being cut even if it is shifted in the width direction of the base material. In addition, since there is no cut at both end portions along the length direction of the base material, there is no problem of being caught on the tape applying device even when it is pulled out by the tape applying device, and a smooth tape applying operation is performed. I can do things.

  Therefore, according to the pressure-sensitive adhesive tape of the present invention, even when the tape is applied using a tape applying device, the adhesive tape is not cut at an unintended portion, and the application work can be performed stably. It is possible to provide an adhesive tape that can be easily cut by hand when necessary.

  In addition, since there is no cut at both end portions along the length direction of the base material, even when the adhesive tape is wound in a roll shape, unevenness due to the notch appears on the side surface. There is nothing. Therefore, even when the adhesive tape is pulled out, there is no interference with the tape dispenser and the like, and an adhesive tape that realizes smooth tape drawing can be provided.

  Further, a plurality of rows of cuts arranged in the length direction of the base material are formed by arranging two rows in the width direction of the base material, and there is no cut between the cut rows of 6 mm or more, preferably 10 mm or more. When an area portion having a width is formed, the area portion can be used as an advertisement area. For this reason, it is possible to display advertisements on the parts that the user sees at least when opening the container, such as lunch boxes and prepared food packaging containers, or other items, adhesive tapes attached to the packaging, etc. This makes it possible to provide an adhesive tape that secures an advertising space that can exhibit a sufficient advertising effect while being easily cut by hand.

  Hereinafter, the adhesive tape 10 according to the present embodiment will be specifically described with reference to the drawings. 1A is a perspective view showing an adhesive tape 10 according to the present embodiment, and FIG. 1B is a plan view showing the adhesive tape 10. 2 is a schematic view showing a state where the adhesive tape 10 according to the present embodiment is applied by the tape applying device 20, and FIG. 3 is a side view showing a state where the adhesive tape 10 according to the present embodiment is applied to a packaging container. FIG. 4 is a partially enlarged perspective view showing an adhesive tape 10 according to another embodiment, and FIGS. 5 and 6 are drawings showing the adhesive tape 10 in a conventional example.

  The pressure-sensitive adhesive tape 10 according to the embodiment shown in FIG. 1 shows a state in which the pressure-sensitive adhesive tape 10 is wound in a roll shape, and this allows the pressure-sensitive adhesive tape 10 to be continuously supplied in a tape applying device 20 described later. . The base material 12 which consists of orient polypropylene exists in the front side of this adhesive tape 10, and the adhesive layer 14 is provided in the back side of the said base material 12, and this is wound and formed. In this embodiment, the base material 12 is formed with cuts 16 extending in the width direction of the adhesive tape 10, and the cuts 16 are arranged at predetermined intervals in the length direction of the adhesive tape 10. Yes. At this time, the cut 16 is formed so as not to reach at least the side edge of the adhesive tape 10, and is specifically stopped at a position of about 1 mm from the side edge of the adhesive tape 10. As a result, the cut edge 16 does not exist at the side edge of the adhesive tape 10 and is in a continuous state.

  In addition, the adhesive tape 10 shown in FIG. 1 has two rows (two rows) formed in the width direction, each having a plurality of cuts 16 provided in the length direction of the adhesive tape 10. As a result, cutting from either side of the adhesive tape 10 in the width direction can be performed by hand without requiring scissors or the like. Actually, when the adhesive tape 10 is cut, by applying a force that tears one of the side edges, the portion between the cut 16 and the side edge is broken, which becomes the cut 16 and applies the force. Can be cut without need.

  In the present embodiment, a region portion 18 where no cut 16 exists is formed between the rows of cuts 16 existing in the length direction of the adhesive tape 10. As shown in FIG. 1B, the area portion 18 can be used as an advertising space for displaying a company name, or can be printed with a design for enhancing the decorativeness of the packaging container. However, the formation of the region portion 18 is optional and can be omitted. In this case, the cut 16 can be formed longer.

  FIG. 2 shows a state in which the adhesive tape 10 formed as described above is applied by the tape applying device 20. As shown in this figure, a packaging container 30 composed of a container main body 32 and a lid 34 is supported by a support base 24, and an adhesive wound in a roll shape on both sides of the packaging container 30. There are rolls of the tape 10, and the adhesive tape 10 is drawn from each roll. The drawn roll tape is held while being sucked by the lower surface of the arm 22 shown in the drawing. At this time, as a matter of course, the adhesive layer 14 exists in a direction facing the packaging container 30. The adhesive tape 10 supplied from the roll is stuck to the packaging container 30 by moving the arm 22 of the tape sticking device 20 so as to trace the outside of the packaging container 30. After the arm 22 of the tape applicator 20 moves to the lower surface of the packaging container 30 and affixes the adhesive tape 10, the adhesive tape 10 is cut, and the adhesive tape 10 is applied to the next place or the next container. Affix it.

  When the adhesive tape 10 is applied by the tape applying apparatus 20, the adhesive tape 10 according to the present invention is a case where the adhesive tape 10 is supplied obliquely to the arm 22 because there is no cut 16 in the side edge portion. However, the pressure-sensitive adhesive tape 10 is not cut, and thus the tape sticking device 20 can be used to perform the sticking operation stably.

  The adhesive tape 10 applied by the tape applying apparatus 20 as described above is cut when the container lid 34 is opened. At this time, the user of the contents of the container confirms the adhesive tape 10 that is securely attached. Therefore, in this embodiment, the region portion 18 is formed between the cuts 16, and the manufacturer is printed on the region portion 18 to be used as an advertisement space or an information description region. As a result, normally, it is possible to surely inform the user of the manufacturer name that is described only in an inconspicuous place such as the bottom surface of the packaging container.

  FIG. 4 shows an adhesive tape 10 according to another embodiment, and in particular, the shape and arrangement of the cuts 16 are different from those of the embodiment shown in FIG. In addition, the arrow (P) in each figure has shown the virtual point which applies force at the time of a cutting | disconnection, and the dotted line has shown the cutting line which may be cut | disconnected when force is applied to the said virtual point. However, as a matter of course, it does not deny the possibility of being cut at a portion different from the chain line.

  First, FIG. 4A is different from the embodiment shown in FIG. That is, in the embodiment shown in FIG. 1, the cut lines 16 are formed in a positional relationship adjacent to each other in the width direction. However, in the adhesive tape 10 according to the embodiment shown in FIG. The cuts 16 are arranged in a staggered pattern in the length direction of the tape. That is, the cuts 16 constituting one of the cut lines 16 are formed so as to exist between the cuts 16 of the other lines. By forming the cut 16 in this way, when this is cut, the cut can be cut at an angle as shown by a chain line in the drawing.

  FIG. 4B is different from the embodiment shown in FIG. 1 in the shape of the cut 16. That is, in the pressure-sensitive adhesive tape 10 according to this embodiment, in addition to the cut 16 extending in the width direction of the base material 12 (the pressure-sensitive adhesive tape 10), the cut 16 extending in the length direction of the base material 12 (the pressure-sensitive adhesive tape 10) is provided. Forming. When formed in this way, the cutting line can be changed according to the direction in which the force is applied when cutting the adhesive tape 10, and in this drawing, for example, the direction orthogonal to the length direction of the adhesive tape 10 When the force P1 is applied, a straight cut can be made in the width direction. On the other hand, when the force P2 is applied from an oblique direction, the path that is most easily cut according to the direction of the force is used. The adhesive tape 10 can be cut.

  FIG. 4C shows an example in which the cut end is formed as a wide hole. In this drawing, an example in which a diamond-shaped hole is formed is shown, but other shapes may be used. However, considering the ease of cutting in the adhesive tape 10, it is desirable that the shape of the hole has a sharp inner angle on both sides in the width direction. The cuts having such hole shapes can also be arranged in a staggered manner as shown in FIG.

The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the gist of the present invention.

  The above-mentioned pressure-sensitive adhesive tape according to the present invention must be peeled off or cut in order to bond the container body and lid of the food packaging container, or in other containers, at least when used or opened. It can be used effectively when it is necessary.

  In addition, it can be used for applications such as bonding or sealing articles, and can be used as a new product that can be easily cut in the width direction of the adhesive tape.
