Summary of the Invention

Problems to be Solved by the Invention

[0004] In the SDGs (Sustainable Development Goals), an international goal adopted at the United Nations Summit aiming for a sustainable and better world by 2030, 17 international goals are listed for the realization of a sustainable, diverse, and inclusive society that leaves no one behind. Among these 17 goals, Goal 12 aims to ensure sustainable production and consumption patterns as "the responsibility to produce and the responsibility to use", and requires, among other things, significantly reducing waste generation. For example, Goal 12-5 aims to significantly reduce waste generation by preventing, reducing, recycling, and reusing waste by 2030. Under such circumstances, it is also required to reduce waste generation in tapes such as packaging tapes used for logistics.

[0005] However, the conventional adhesive tapes and tape cutters, etc. are used by cutting them to a predetermined length, and there is no idea of stretching the length in the first place, and there is no idea of reducing the generation of waste by reducing the amount of tape used.

Means for Solving the Problems

[0006] The present invention provides the following means in order to enable reducing the generation of waste by reducing the amount of tape used, etc.

[0007] One means of the present invention is an adhesive tape having an adhesive surface with an adhesive body on one surface, It is perforated in a perforated pattern in the width direction, and the perforations are made such that the adjacent perforations are staggered in the extending direction, Characterized in that it can be stretched in the extending direction in a net-like decoration and used, An adhesive tape.

[0008] According to the above adhesive tape, since the tape can be pulled and stretched in the extending direction in a net-like decoration and used, when closing the lid of a packing material such as cardboard, the length can be stretched about 40% compared to a tape without perforations. As a result, the amount of tape used can be suppressed. Thereby, the waste generated after using the tape can be reduced.

[0009] One means of the present invention is a tape dispenser capable of pulling out an adhesive tape having an adhesive surface with an adhesive body on one surface and cutting it to a predetermined length, A cylindrical support roller that rotatably supports a wound tape having an adhesive tape wound in a ring shape, A blade roller having blade bodies arranged in parallel in the axial direction on the surface of a cylindrical roller at intervals and arranged in a staggered manner in the circumferential direction, which abuts against the adhesive tape pulled out from the winding tape supported by the support roller while rotating, makes cuts in a perforated pattern in the width direction of the adhesive tape, and makes the cuts so that adjacent cuts are staggered in the extending direction of the adhesive tape. A cutting portion for cutting the adhesive tape with the cuts made therein. The adhesive tape is characterized in that it is made available by being stretched in a net-like pattern by the staggered cuts made in the adhesive tape. It is a tape dispenser.

[0010] According to the above tape dispenser, by pulling the pulled-out adhesive tape, the adhesive tape can be stretched in the extending direction in a net-like pattern and used. Therefore, when closing the lid of a packaging material such as cardboard, the length can be extended by about 40% compared to an adhesive tape without cuts. As a result, the usage amount of the adhesive tape can be suppressed. Thereby, the waste generated after using the adhesive tape can be reduced.

[0011] In the above tape dispenser, preferably, the blade roller is arranged to abut against the surface of the adhesive tape opposite to the adhesive surface.

[0012] According to the above tape dispenser, since the cuts are made from the surface opposite to the adhesive surface, it is configured to be able to smoothly pull out the adhesive tape while making the cuts.

[0013] In the above tape dispenser, preferably, in a plan view in a plane perpendicular to the axial direction of the support roller, The blade roller is arranged so as to overlap a middle position of a tangent line located on the surface of the adhesive tape opposite to the adhesive surface among two tangent lines of the support roller that form a straight line passing through the tip of the cutting portion.

[0014] According to the above tape dispenser, since the adhesive tape abuts against the blade roller in a state where it is pulled, it is possible to configure the adhesive tape to be easily cut effectively.

Mode for Carrying Out the Invention

[0016] An embodiment of the tape dispenser of the present invention will be specifically described with reference to the drawings. However, the embodiments described below are merely examples of the present invention and do not limit the technical scope of the present invention. In each drawing, the same components are denoted by the same reference numerals, and the description thereof may be omitted. In this specification, an adhesive tape having an adhesive on one surface may be simply referred to as a "tape".

[0017] <Embodiment 1> <Schematic Configuration of Tape Dispenser> FIG. 1 is a perspective view of the tape dispenser 1. FIG. 2 is a perspective view of the tape dispenser 1 with the cover 3 removed.

[0018] As shown in the figure, the tape dispenser 1 is composed of a main body 2 and a cover 3. In the internal space formed by the main body 2 and the cover 3, a wound tape 9 having a tape wound in a ring shape is accommodated, and the tape 91 with a cut made by the blade roller 5 is pulled out from the outlet 22 where the cutting part 6 is arranged.

[0019] The wound tape 9 used in the tape dispenser 1 is an adhesive tape having an adhesive surface with an adhesive on one side. The adhesive surface of the wound tape 9 is the inner surface of the ring, and the cutting part 6 abuts on the surface opposite to the adhesive surface of the tape 91 pulled out from the wound tape 9.

[0020] <Main body 2> Figure 3 is a plan view of the main body 2 in a state where the wound tape 9 is accommodated. As shown in Figures 2 and 3, the main body 2 includes an outlet 22, a support roller 4, a blade roller 5, a blade roller support part 54, a cutting part 6, a guide 7a, a main body side surface part 81, and a main body outer peripheral part 82. The outlet 22 is an opening through which the tape 91 pulled out from the wound tape 9 is pulled out. The main body 2 is formed of, for example, resin.

[0021] <Cover 3> Figure 4 is a plan view of the cover 3. As shown in Figure 4, the cover 3 includes an inner roller 4a, a cylindrical part 54a, a guide 7b, and a cover side surface part 83. The cover 3 is detachably attached to the main body 2. An inner roller 4a is formed at a position on the cover side surface part 83 that faces the through hole 23a of the support roller 4 of the main body 2. The inner roller 4a is located inside the support roller 4 of the main body 2 when the cover 3 and the main body 2 are connected. The inner roller 4a is a hollow cylindrical roller and is annular with a circular through hole 23 inside. That is, the through hole 23 is a circular opening. The cylindrical part 54a is located inside the blade roller support part 54 of the main body 2 when the cover 3 and the main body 2 are connected. When the main body 2 and the cover 3 are connected, a case (housing) of the tape dispenser 1 is formed, and thereby an internal space of the tape dispenser 1 is formed. The cover 3 is formed of, for example, resin.

[0022] The main body side surface portion 81 of the main body portion 2, together with the cover side surface portion 83 of the cover 3, forms the side surface of the tape dispenser 1. The main body outer peripheral portion 82 of the main body portion 2 is formed so as to connect the main body side surface portion 81 and the cover side surface portion 83 and cover the outer peripheries of the support roller 4 and the blade roller 5.

[0023] The main body outer peripheral portion 82 has a tape pressing portion 21 formed by being partitioned by a U-shaped through hole. The main body portion 2 is formed of resin, and the tape pressing portion 21 has a certain degree of flexibility. The tape pressing portion 21 is pressed inward of the tape dispenser 1 by applying pressure from the outside by the user and comes into contact with the surface of the wound tape 9 accommodated in the tape dispenser 1. Thereby, the rotation of the wound tape 9 can be suppressed. For example, when the user cuts the tape 91 pulled out from the wound tape 9, the user can press down the tape pressing portion 21 to suppress the rotation of the wound tape 9.

[0024] As shown in FIG. 2 and the like, two cylindrical protrusions 24 are provided outside the lead-out port 22 of the main body portion 2. The cylindrical protrusions 24 are provided with the width direction of the tape 91 as the axial direction. These protrusions 24 are located on the adhesive surface side of the tape 91 and are used, for example, to temporarily attach and hold the tape 91 pulled out from the lead-out port 22.

[0025] <Support roller 4> The support roller 4 is a hollow cylindrical roller that rotatably supports the wound tape 9. In other words, the support roller 4 is annular with a through hole 23a inside. The outer periphery of the support roller 4 is smoothly curved so that the wound tape 9 being supported rotates smoothly. Although the support roller 4 itself of the present embodiment is fixed, it may be configured such that the outer periphery rotates in accordance with the rotation of the wound tape 9.

[0026] <Blade roller 5> FIG. 5 is a perspective view of the blade roller 5. As shown in FIG. 5, the blade roller 5 is a hollow cylindrical, i.e., annular roller, and has a plurality of blade bodies 51 on its surface. These blade bodies 51 are arranged in a plurality of rows at intervals in a linear shape parallel to the axial direction of the blade roller 5, and are provided so as to be staggered in the circumferential direction. The blade roller 5 is formed by arranging an annular blade member 53 made of metal on the circumferential surface of a hollow cylindrical, i.e., annular roller body 52 made of resin. The blade member 53 is fixed to the roller body 52 by adhesion or the like. The blade member 53 is formed by raising an annularly formed metal member so that the portion that becomes the blade body 51 stands up, and polishing the portion that becomes the blade body 51 so that the end face of the blade body 51 becomes the blade tip.

[0027] The blade roller 5 is attached to the hollow cylindrical, i.e., annular blade roller support portion 54 of the main body portion 2 and is rotatable with respect to the blade roller support portion 54. The blade roller 5 contacts the tape 91 pulled out from the winding tape 9 supported by the support roller 4 while rotating, makes cuts in a perforated pattern in the width direction of the tape 91, and makes the cuts such that adjacent cuts are staggered in the extending direction of the tape 91. The blade roller 5 is arranged so as to contact the surface of the tape 91 pulled out from the winding tape 9 that is opposite to the adhesive surface.

[0028] As shown in the plan view of the main body portion 2 in FIG. 3, in a plan view in a plane perpendicular to the axial direction of the support roller 4, the blade roller 5 is arranged so as to overlap a position in the middle of the tangent line A1, which is the tangent line located on the surface opposite to the adhesive surface, among the two tangent lines A1 and A2 of the support roller 4 that are straight lines passing through the tip 61 of the cutting portion 6.

[0029] <Cutting portion 6> The cutting portion 6 is arranged outside and in the vicinity of the lead-out port 22 of the main body portion 2, and cuts the tape 91 with cuts made by the blade roller 5 and pulled out from the lead-out port 22. The cutting portion 6 is a blade body having a blade tip. The cutting portion 6 may adopt a conventional configuration as long as it can cut the tape 91.

[0030] <Guide 7a, 7b> The guides 7a and 7b (see FIGS. 3 and 4) are each cylindrical members disposed between the support roller 4 and the blade roller 5. The guides 7a and 7b guide the tape 91 toward the blade roller 5 while contacting the surface of the tape 91 opposite to the adhesive surface. The guides 7a and 7b contact both ends in the width direction of the tape 91.

[0031] <Tape> FIG. 6 is a plan view of the tape 91 pulled out from the tape dispenser 1. FIG. 7 is a plan view showing the state where the pulled-out tape 91 is extended.

[0032] As shown in FIG. 6, the tape 91 pulled out from the tape dispenser 1 has perforations 92 formed in a perforated pattern in its width direction, and the adjacent perforations 92 in the extending direction are staggered. When the user pulls the tape 91 in the extending direction to extend it in this state, it becomes a net-like decoration as shown in FIG. 7. The tape 91 in the net-like decoration state becomes about 40% longer compared to the tape without perforations. Therefore, compared to the wound tape 9 used without using the tape dispenser 1, it can be used for an area about 40% longer. As a result, the wound tape 9 can be used about 1.4 times longer, and when used in the same length area, the usage amount of the wound tape 9 can be reduced to about 71% (≒1 / 1.4).

[0033] <Modification example> The tape dispenser 1 of the above embodiment can adopt the following modification examples. The modification examples described below do not limit the interpretation of the present invention and are described as specific examples.

[0034] The materials of each component forming the tape dispenser 1 described in the embodiment are merely examples, and it may be formed of any material.

[0035] The support roller 4 and the blade body roller 5 may each be a solid cylindrical shape instead of a hollow cylindrical shape. When the blade body roller 5 is a solid cylindrical shape, the roller body 52 is a solid cylindrical shape. However, it is preferable to make the support roller 4 and the blade body roller 5 into a hollow cylindrical shape, that is, an annular shape, because the amount of material such as resin used to form them is reduced.

[0036] The blade body roller 5 does not necessarily have to be configured to have the roller body 52 and the blade body member 53, and may be a single annular or cylindrical member having the blade body 51 described in the embodiment. Further, the blade body 51 or the blade body member 53 may be formed of resin or ceramic instead of metal.

[0037] In the embodiment, the winding tape 9 was described as an adhesive tape having an adhesive surface on one side, but the winding tape 9 is not limited to such an adhesive tape. The winding tape 9 may be configured not to have an adhesive surface, or may be a so-called double-sided tape having adhesive surfaces on both sides. Further, the winding tape 9 may be a tape that does not have an adhesive surface. Further, the winding tape 9 may be configured such that no adhesive is applied to the tape 91 pulled out from the winding tape 9.

[0038] <Features of the Embodiment> As described above, the tape dispenser 1 illustrated with the embodiment and the modification has the following features.

[0039] The tape dispenser 1 can pull out an adhesive tape having an adhesive surface with an adhesive body on one side and cut it to a predetermined length, and includes a support roller 4, a blade roller 5, and a cutting portion 6. The support roller 4 is cylindrical and rotatably supports a wound tape 9 having a tape wound in an annular shape. The blade roller 5 has blade bodies 51 arranged in a plurality of rows at intervals in a linear shape parallel to the axial direction on the surface of the cylindrical roller, and provided so as to be staggered in the circumferential direction. The blade roller 5 contacts the tape 91 pulled out from the wound tape 9 supported by the support roller 4 while rotating, makes perforations in a zigzag pattern in the width direction of the tape 91, and makes perforations so that the adjacent perforations are staggered in the extending direction of the tape 91. The cutting portion 6 cuts the tape 91 with perforations. The pulled-out tape 91 can be used by being stretched in a net-like pattern by the staggered perforations made in the tape 91. With such a configuration, the tape dispenser 1 can suppress the amount of the wound tape 9 used. Thereby, the waste generated after using the tape can be reduced.

[0040] Further, the blade roller 5 is arranged to contact the surface of the tape 91 opposite to the adhesive surface. Thereby, it is configured to be able to smoothly pull out the tape 91 while making perforations in the tape 91.

[0041] Further, the blade roller 5 is arranged to overlap a middle position of a tangent line A1, which is a tangent line located on the surface of the tape 91 opposite to the adhesive surface, among two tangent lines A1 and A2 of the support roller 4 that are straight lines passing through the tip 61 of the cutting portion 6 in a plan view in a plane perpendicular to the axial direction of the support roller 4 (plan view of FIG. 3). Thereby, since the tape 91 is in a state of being pulled and contacts the blade roller 5, it can be configured to be easily and effectively perforated with respect to the tape 91.

[0042] Further, the tape 91 which is an adhesive tape is an adhesive tape having an adhesive surface on one side, and is perforated in a zigzag pattern in the width direction, and the adjacent perforations are staggered in the extending direction, and it can be used by being stretched into a net-like decoration.
