Description

  The present invention relates to a partition plate for tapes. In particular, the present invention relates to a partition plate for tapes used when stacking and packaging a single tape or a plurality of tapes wound in a disk shape, for example, several to several tens.

Examples of methods for packing a plurality of tapes using a packaging box include I) a release paper insertion packaging method, II) a paper tube fixed packaging method, and the like.
The above-described method will be explained. First, I) the release paper insertion and packaging method is a method of stacking a plurality of tapes so that the side surfaces of the tapes overlap each other. This is a method of inserting a paper or a release film made of a plastic film which has been peeled on one or both sides between a single roll. In this method, when tapes are wound and wrapped so that the side faces overlap each other, the adhesive will be removed from the tape due to changes in environmental conditions such as temperature and humidity. It is a packaging method that improves the problem of oozing out from the side surface and sticking the single rolls and having to use them while peeling off each single roll. Tapes can be inserted by inserting release paper. It is excellent in that it prevents adhesion between the single rolls.

For example, in Patent Document 1, in a package in which a plurality of single tapes are stacked, between both single tapes, a single sheet of paper such as kraft paper or glassine paper is provided with silicon resin or polyethylene film. And a method of preventing adhesion of single rolls due to seepage from the side surface of the adhesive tape by inserting double-sided release paper that has been subjected to release treatment with silicon resin, wax, or the like.
In this method, both sides of the paper are released, so only one double-sided release paper is inserted between the single roll and the single roll can be taken out one by one when using tapes. Good workability is excellent.

Also, II) the paper tube fixed wrapping method is such that when a plurality of tapes are stacked and accommodated so that the side surfaces of the single windings of the tapes overlap, the fixing cores are passed inside the tape cores, etc. Thus, the tape is fixed. In this method, since the tapes are fixed by a fixing core passed inside the tape cores, the tapes do not collapse even if lateral pressure is applied to the tapes when transporting the tapes. It is excellent in that it can be packaged in a good-looking manner without damaging the tapes.
For example, in Patent Document 2, in a tape packaging box, a support can be fixed to a packaging box material by providing a notch in each of a pair of top plate flaps and the bottom flaps. A long tape packaging box is disclosed. In this method, the struts for fixing the tapes are fixed to the packaging box material, so that the tapes can be prevented from collapsing during the transportation and storage of the tapes. Since it is not necessary to prepare separately, the packaging cost is low and the workability of the packaging work is excellent.

  However, in the method disclosed in Patent Document 1, since the double-sided release paper is made of a thin and soft material such as paper or a plastic film, when the tapes are stored for a long period of time, the telescopes are raised in the shape of bamboo. The occurrence of the phenomenon cannot be suppressed. Also, when transporting and storing tapes that have been stacked in multiple wraps in a packaging box, the tapes are wrapped because only double-sided release paper is inserted between the single rolls of tape. It is not fixed to the box material, causing collapse of goods due to vibration, tapes are deformed or damaged by impact, the appearance is damaged, local pulling causes tapes to become locally heavy, There remains a problem that the drawing force is not constant, or the tape breaks when the tape is pulled out due to a cut of the tape caused by friction or the like.

In addition, the packaging method disclosed in Patent Document 2 requires a packaging box having a notch portion corresponding to each size of the paper tube diameter in each of the top plate in-plane flap and the bottom surface flap. However, it is expensive and time-consuming to produce such a packaging box for each paper tube diameter, and it is difficult to store and manage. In addition, since the length of the support supports the height of the packaging box in this tape packaging method, the number of tapes to be packed in the packaging box material is regulated, and it can respond precisely to individual requirements. The problem of not being able to do it remains. For example, in the case of a packaging box for 10 tapes, if 10 tapes are not necessarily packed, a gap will be created in the packaging box material, and vertical pressure will be applied to the tapes during transportation and the tapes will be deformed. It may not be possible to meet individual requirements because it may be damaged or damaged, and it is necessary to prepare a cushioning material to fill the gap separately from the packing box and tape fixing column, which is costly and troublesome There is a problem such as.
JP-A-53-16737 Japanese Patent Laid-Open No. 9-295633

  In order to solve such problems, the present invention prevents the adhesive from seeping out from the side surface of the tape when the package body in which a plurality of tapes are stacked and packaged so that the side surface and the side surface overlap each other is stored for a long period of time. Can prevent adhesion of single rolls, telescope phenomenon, tape properties, etc., and deterioration of product quality such as collapse of packaging and damage to tapes during transport. It aims at providing the partition plate for tapes.

As a result of intensive studies to achieve the above-mentioned problems, the present inventors have made the present invention.
That is, the present invention is as follows.
1. A partition plate for partitioning each tape when stacking tapes wound around a winding core, and having a convex portion for fixing the inside of the winding core to one surface of the partition plate A partition plate for tapes.
2. 1. It has a fitting structure for connecting partition plates to the surface opposite to the surface having the convex portion. The partition plate for tapes of description.
3. The length of at least a part of the line segment connecting the center of the convex portion and the end of the partition plate is larger than the radius of the winding core of the tapes. Or 2. The partition plate for tapes as described in 2.
4). The height of the convex part is 0.2 times or more and 1.9 times or less of the winding core width. Or 2. The partition plate for tapes of description.
5. 1. The adhesive stripping treatment is performed on at least one side of the partition plate. Or 2. The partition plate for tapes of description.
6). 1. At least one side of each side of the plurality of tapes ~ 5. A method of stacking tapes, wherein the tapes and the partition plates are stacked using a partition plate fitting structure.
7). 5. The fitting structure is a structure in which connecting partition plates are connected to each other. A method for collecting the tapes as described.
8). 6. above. Or 7. A method for packing tapes, which further comprises binding a plurality of tapes and partition plates collected in step (1).

The most different point of the present invention from the prior art is that the tape packing method of the prior art simply inserts a release paper between a single roll of tapes or inserts a support column inside the tape roll core. However, the packaging method using the tape partition plate of the present invention is not only for long-term storage but also for transportation, whereas it is only suitable for long-term storage or transportation of tapes. It is also a point that can deal with problems such as damage in
The effect of the present invention is that the conventional tape packaging method simply inserts a release paper between a single roll of tapes or inserts a support column inside the tape roll core. The packaging method only supports long-term storage or transportation of tapes, and it is impossible to suppress the occurrence of telescope phenomenon in which tapes rise into a bamboo shoot shape during long-term storage and transportation of tapes. Problems such as collapse of goods due to vibration, and the production of packaging boxes corresponding to the paper tube diameter, outer diameter, and number of packaging of tapes are expensive and troublesome, and are difficult to store and manage. Since the length of the column corresponds to the problem and the height of the packaging box, the number of tapes to be packed in the packaging box material is regulated, and it is not possible to respond precisely to each requested number Etc. The tape partition plate of the present invention and the packing method using the tape partition plate are provided with a tape partition plate on the side of the tape when the tapes are stored for a long period of time, and the tape partition plate and the tape are bound together. Or by adjusting the weight of the partition plate, it is possible to suppress the occurrence of the telescope phenomenon of the tapes. Moreover, since the partition plate for tapes of this invention has a convex part only on one surface of this partition plate, when packing multiple tapes using a packaging box, it is for tapes and tapes. Since the volume of the laminate can be reduced by making the top and bottom surfaces of the laminate of the partition plates the back side of the surface having the convex part, the voids in the package can be reduced and the transportation cost is reduced. be able to. In addition, if the surfaces opposite to the surfaces having the convex portions of the partition plate are connected to each other so as to have convex portions on both surfaces of the partition plate, individual tapes can be attached to both sides of the tapes. Since it can be clamped from the surface, it is possible to more reliably suppress the occurrence of telescope reduction of individual tapes. Further, the partition plate for tapes of the present invention can exhibit the effect as a double-sided release paper as long as the surface where the partition plate and the tape are in contact is subjected to an adhesive peeling treatment.

In addition, when transporting tapes, the inside of the tape core is fixed by the convex part of the tape partition plate to prevent the tapes from collapsing due to vibration during transportation and to prevent deformation and scratches on the tapes. An excellent effect such as prevention can be exhibited.
Further, when the outer dimension of at least one of the tape partition plates is larger than the outer dimension of the tapes wound in a disk shape, the tape partition plates also play a role of protecting against external impacts.

Hereinafter, the present invention will be described in detail, particularly focusing on preferred forms thereof.
The tape partition plate will be described with reference to FIG. The partition plate for tapes of this invention is comprised from 1) tapes fixed surface of a board part, and 2) partition plate fixed surface. Here, FIG. 1A is a perspective view of a partition plate for tapes when the “tape fixing surface” of the plate portion is the upper surface, and FIG. 1B is a surface opposite to the tape fixing surface of the plate portion. It is a perspective view of the partition plate for tapes when the "partition plate fixed surface" which is is the upper surface.
The 1) tape fixing surface described above will be described. First, the tape fixing surface means a surface having a convex portion for fixing the inner side of a core of a tape wound in a disk shape. Here, the effect of fixing the inner side of the tape winding core with the convex part of the partition plate is to prevent the collapse of the load during the transportation of the tape, the deformation or damage of the tape, regardless of the size or winding shape of the tape. It is a point that can be prevented. For example, if the convex part is not inside the tape core, but outside the outer periphery of the tape, every time the outer diameter or shape of the tape is different, the labor and cost of manufacturing a partition plate of a new size or shape is reduced. Although it is necessary, when fixing the inside of the tape core, the tapes can be clamped by the same partition plate regardless of the outer diameter or shape of the tape if the diameter of the core is the same.

The convex part of the tape fixing surface will be described.
The convex part of the tape fixing surface of the partition plate for tapes can fix the inside of the tape winding core, and if the tapes can be easily fitted into the convex part, the size, shape, height of the convex part, There are no particular restrictions on the number of pieces. For example, the inside of the core of the tape may be fixed with a single convex portion as shown in FIG. 2, or may be fixed with a plurality of convex portions as shown in FIG. The shape of the convex portion is not particularly limited as long as the inside of the core of the tape can be fixed. Even if it is a cylindrical shape as shown in FIG. 4 (perspective view), the bottom surface is a triangle, a rectangle (rectangle, square) ) Other polygonal prisms, rhombuses, ellipses, indeterminate columns made of curves, spheres, cones, triangular pyramids, pyramids, etc. It may be an amorphous solid composed of curved surfaces. Furthermore, it is preferable that there is some play between the tapes and the convex portions from the viewpoint of ease of taking out the tapes from the convex portions. Here, examples of the fixing method of the tapes by the convex portion include 1) a point fixing method, 2) a bar fixing method, and 3) a column body fixing method.

  Here, 1) the point fixing method means that the inner side of the tape core and the tape fixing part are fixed by point contact, as shown in FIG. Although there is no limitation, from the viewpoint of securely fixing the tapes, it is preferable that the inner side of the tape core and the tape fixing part are in contact at both ends of at least the longest inner side of the tape core, and the contact point is 3 It is more preferable that the contact is made at a point or more. Further, from the viewpoint of stably fixing the tapes, it is more preferable that the contact points are arranged at equal intervals with respect to the tape core inner diameter.

  2) The bar fixing method means that at least one bar-shaped tape fixing portion is fixed to the inner side of the tape core as shown in FIG. From the viewpoint of fixing the tapes, there is no particular problem if the length of the bar is equal to or less than the longest part of the inner diameter of the tape core, but if the bar is made of a hard material such as polystyrene (PS) resin, the bar Is preferably 0.9 times or more and 1.0 times or less of the longest inner diameter of the core of the tape, and a more preferable bar length is 0.92 times or more of the longest inner diameter of the tape. 99 times or less, more preferably 0.95 times or more and 0.99 times or less of the longest inner diameter of the tape core. Also, when the bar is made of a compressible material such as soft rubber, even if the length of the bar is longer than the tape core inner diameter by compressing the convex part in the tape core inner diameter direction, the tape is wound. There is an advantage that it can be inserted into the core, and further, after the tapes are inserted inside the core, the inside of the core can be more reliably fixed. Therefore, when the bar is made of a compressible material, the preferable length of the bar is 0.92 times or more and 1.2 times or less of the longest inner diameter of the core of the tape, and the more preferable length of the bar is the tape winding. It is 0.95 times or more and 1.15 times or less of the longest inner diameter part of the core, and more preferably 0.95 or more and 0.99 times or less of the longest inner diameter part of the tape winding core. In addition, from the viewpoint of stably fixing the tapes, the number of bars is preferably two or more, and the contact portions of the bars and the inner side of the tape core are arranged at equal intervals with respect to the inner diameter of the tape core. More preferably.

  3) As shown in FIG. 7, the column fixing method means a method of fixing the inside of the core of the tape with a column. There are no particular restrictions on the shape and size of the column, but the size of the bottom of the column is at least one side of the bottom of the column (diameter in the case of a cylinder) from the viewpoint of preventing deformation of the tape due to impact, etc. ) Is preferably 0.9 times or more and 1.1 times or less, more preferably 0.95 times or more and 1.05 times or less of the inner diameter of the core of the tape. Further, from the viewpoint of easy removal of the tapes, the bottom area of the column body is more preferably 0.95 times or more and 0.99 times or less of the core inner area of the tapes. Further, from the viewpoint of stably fixing the tapes, the most preferable shape of the column is when the column shape and the shape inside the tape core are the same.

  Furthermore, it is preferable that the height of the convex portion is not less than 0.2 times and not more than 1.9 times the tape core width from the viewpoint of fixing the tapes. Here, if the height of the convex portion is less than 0.2 times, it is impossible to stably fix the inner side of the tape winding core, so that when the lateral pressure is applied to the tape, the tape is displaced from the convex portion, And the tapes may be crushed or deformed. On the other hand, if the height of the convex portion is equal to or greater than the tape core width, if the convex portion is used as a connecting projection as shown in FIG. 8, the excess portion of the protruding portion can be obtained by adjusting the depth of the connecting hole. Can be absorbed, and tapes can be pinched firmly. Tape deformation, notches and scratches can also be prevented. Therefore, from the viewpoint of stably fixing the tapes, a more preferable height of the convex portion is 1.1 times or more and 1.7 times or less of the tape core width, and more preferably 1 of the tape core width. .2 to 1.5 times.

  Further, the shape of the tape fixing surface is not limited as long as the tape can be clamped and fixed, and even if it is circular as shown in FIG. 9, it is triangular, quadrangular (rectangular, square), and many other types. It may be rectangular, rhombus, ellipse, or an amorphous shape with curves, but from the viewpoint of sandwiching the tapes, when the tapes are fitted into the convex parts, the outer dimensions of the plate part are It is preferably longer than the outer diameter, and more preferably the outer dimensions of the two orthogonal directions are longer than the outer diameter of the tapes. Further, it is more preferable that the outer dimension of the plate portion in all directions is longer than the outer diameter of the tapes. Here, when laminating the partition plates for tapes between single rolls of tapes, outer dimensions longer than the outer diameter of the tapes are not laminated only in the same direction, but in different directions. It is preferable from the viewpoint of protecting the tapes from external impacts when transporting and storing the tapes. For example, as shown in FIG. 10, it is preferable that the partition plates are rotated 90 degrees in a direction orthogonal to each other and stacked so that the outer periphery of the package is larger than the outer diameter of the tape.

  Further, the surface where the tape fixing surface and the tape are in contact (the surface where the partition plate and the tape contact when the partition plate and the tape are integrated) is flat as shown in FIG. As shown in FIG. 12, there may be irregularities, which can be appropriately selected depending on the size and shape of the tapes, the adhesive used, and the like. For example, if the portion of the tape fixing surface that is in contact with the tape is flat, the entire surface of the tape can be clamped, so that deformation of the tape due to impact, telescope phenomenon, or the like can be reliably prevented. Also, in the case of tapes having an adhesive layer, the surface where the plate part and the tapes come in contact have a plurality of convex parts or concave parts, or the plate part surface is corrugated, the tapes and tapes Since the contact area with the sandwiching portion is reduced, even if the adhesive oozes out from the side surface of the tape during storage of the tape, it is possible to reduce the adhesion of the tape to the tape fixing surface.

The partition plate fixing surface will be described.
The partition plate fixing surface referred to in the present invention is a surface on the surface opposite to the tape fixing surface, and means a surface having a fitting portion for connecting the tape partition plates.
Here, the fitting portion refers to an unevenness for connecting the partition plates for tapes when the partition plates for tapes are abutted with each other. The convex portion of the tape fixing surface and the back surface thereof, that is, the partition plate A concave portion corresponding to the convex portion of the fixed surface is also included. A convex part is called a connection projection part, and a recessed part is called a connection hole. The fitting part has such a size that the connecting projection fits into the connecting hole, and if the partition plates for tapes can be connected to each other, there is no particular restriction on the location and size of the fitting part, and at least the partition plate fixing surface It suffices to have one or more places on the surface. Further, the cross-sectional shape of the connecting protrusion and the connecting hole may be a quadrangle, a circle, an ellipse, a polygon other than a quadrangle, or an indeterminate form including a curve or a straight line. Furthermore, the fitting of the fitting portion is generally roughly divided into three types, that is, gap fitting, interference fitting, and dead fitting, and may be appropriately selected according to the application. Here, the gap fitting is a fitting with a gap between the connection protrusion and the connection hole when the connection protrusion is inserted into the connection hole. On the other hand, the interference fit is difficult to come off when two partition plates for tapes are connected due to the fit with a tightening gap between the connection protrusion and the connection hole when the connection protrusion is inserted into the connection hole. It has the advantage of being strong against impacts during transportation and storage. Furthermore, the interference fit is an fit that allows clearance or interference due to tolerance between the gap fit and the interference fit, and requires dimensional accuracy when forming the connecting projection and the connecting hole, which is considerably expensive in cost. The fitting is easy to remove. When the cross section of the connecting hole is larger than the cross section of the convex portion, the convex portion of the tape fixing surface may be used as the connecting projection as shown in FIG.

Next, the material of the partition plates for tapes will be described. The material of the partition plate for tapes is not particularly limited as long as it can be formed into a plate shape and can hold the tapes, and examples thereof include paper, resin, wood, metal, etc. alone or a combination thereof. From the viewpoint that the lighter the total weight of the packaging material, the easier it is to transport and carry, it is preferably made of paper, resin, metal or a composite thereof, more preferably made of paper or resin. preferable. Further, from the viewpoint of durability and moisture resistance and being able to be used repeatedly, it is more preferable to use a resin or a resin-based material.
Moreover, the occurrence of the telescopic phenomenon of tapes can be suppressed by adjusting the weight of the partition plate. If you want to increase your weight, you can use heavy materials or increase the thickness of the plate. Furthermore, it can connect so that the surface opposite to the surface which has a convex part of a partition plate may be put together, and it can also be used so that it may have a convex part on both surfaces of a partition plate.

Moreover, you may provide the recessed part corresponding to the convex part for winding core fixation in the partition plate fixing surface like FIG. In this case, the convex portion and the concave portion can be fitted, and the convex portion height is preferably larger than the winding core width.
Here, the paper used for the partition plates for tapes may be any paper generally used for writing, printing, packaging, etc., for example, kraft paper, glassine paper, parchment paper, cardboard, cardboard, synthetic paper, etc. Laminate the surface of the partition plate with a resin film or metal thin film on these papers, waterproof with water-repellent chemicals / resins, and even black resin films or inorganic materials. They may be bonded together to give light-shielding and moisture-proof effects, or may be subjected to an adhesive peeling treatment.

  The resin used for the partition plates for tapes means a thermoplastic resin or a thermosetting resin. For example, in a thermoplastic resin, a polyethylene resin, a polypropylene resin, a polystyrene resin, a methacrylic resin, a polyvinyl chloride resin, a polyamide resin, Examples of the thermosetting resin include urea resin, melamine resin, xylene resin, phenol resin, unsaturated polyester resin, and the like, and examples thereof include single resins or copolymer resins. The partition plate for tapes is formed from a sheet having a single layer or a multilayer structure composed of these resins, and a thermoplastic resin is preferable from the viewpoint of moldability. In addition, the surface of the partition plate is laminated to these resin films with a metal thin film, etc., waterproofed with a water-repellent drug / resin, further mixed with a black pigment, or an inorganic material is pasted. In addition, a light-shielding effect and a moisture-proof effect may be given, or an adhesive peeling treatment may be performed.

  Moreover, the material of the partition plates for tapes may not be composed of the same material. For example, if the tape fixing surface of the tape partition plate is made of a resin having good releasability from the tape, and the convex portion is made of a material such as impact-resistant rubber, it will be a single partition plate. Multiple effects can be exhibited. In addition, if rubber with high friction with the tapes is sealed on the part of the tape partition plate that comes into contact with the tapes on the fixed surface of the tapes, the tapes will not shift when an impact is applied to the tapes. Tapes can be transported and stored stably.

Next, the thickness of the partition plate for tapes will be described.
First, the thickness of the tape partition plate means the thickness of the plate portion excluding the convex portion and the connecting projection portion, not the thickness of the entire tape partition plate. Here, the thickness of the partition plate for tapes can be appropriately selected depending on the use and material of the partition plate for tapes. However, if the thickness of the plate part is too thin, it does not cost, but the plate part has no strength, so transportation・ Tape may be crushed or deformed when shocked during storage. Conversely, if the tape partition plate is too thick, the partition plate will serve as a cushioning material when shocked during transportation and storage, preventing damage and deformation of the tape, and moderate weight. However, the tape dividers act as weights that hinder the telescope phenomenon of tapes, but the cost increases and the volume of the packaging material increases, resulting in wasteful transportation and transportation costs. Have the problem of Therefore, if the thickness of the partition plate for tapes is too thin or too thick, the desired effect of the present invention cannot be exhibited sufficiently.

Accordingly, the thickness of the partition plate for tapes depends on the size and material of the partition plate for tapes, the state inside the partition plate (hollow, foam, etc.), the base material of the tapes, etc., and can be selected as appropriate. For example, when a cellophane tape having a width of 50 m and a width of 10 mm is sandwiched between partition plates for tapes made of a rigid material such as polystyrene (PS), the preferred thickness is 50 μm to 20 mm, but the same material is the same. Even if it is a partition plate for tapes, since the impact resistance is inferior if the partition plate is hollow, it is preferable to increase the thickness of the partition plate for tapes, and the preferred thickness is 2 mm to 50 mm. is there.
The peeling process of the partition plates for tapes is demonstrated.

The peeling treatment applied to the partition plates for tapes in the present invention means that a release agent is applied to the surface of the partition plates for the purpose of lightly peeling the tapes having an adhesive layer from the partition plates for tapes, Examples include low-adhesive materials with low surface energy, such as silicon and linear alkyl, emulsion solvent types such as fluororesins and polyester resins, and solvent-free types. The adhesive may be appropriately selected depending on the adhesion to the material of the partition plate and the peel strength when the tapes are peeled off from the partition plate. For example, when a linear alkyl release agent is applied to a partition plate for tapes made of low density polyethylene (LDPE), the application amount of the release agent is preferably 0.01 to 0.5 g / m ² .

  Further, a moisture-proof treatment may be performed on the surface of the tape partition plate. Moisture-proof treatment here refers to tape partitions for the purpose of preventing tape bases and adhesives from swelling due to environmental temperature, humidity, etc., causing nests in the tapes, and telescope phenomenon. It means that a moisture-proof material is applied to or pasted on the board. The moisture-proof material is not particularly limited as long as it has a moisture-proof effect, and examples thereof include low-density polyethylene (LDPE), high-density polyethylene (HDPE), and various resin films having other moisture-proof effects. Further, a moisture-proof layer may be formed by applying a liquid moisture-proof material. Also, the thickness of the moisture-proof material is not particularly limited and is appropriately selected depending on the application, but the moisture-proof effect increases as the thickness increases. For example, when low density polyethylene (LDPE) is used, a necessary and sufficient moisture-proof effect can be obtained by setting the thickness to 10 to 60 μm.

It should be noted that the separation treatment and moisture proofing treatment for the tape partition plates can produce an effect if they are provided only on the surface in contact with the tapes, but the tape partition plates are particularly made of paper. In such a case, the single-sided processing has a problem that the tape partition plate is likely to warp due to environmental changes such as temperature changes, so double-sided processing is preferable from the viewpoint of ease of use.
Furthermore, it is not necessary for the partition plate for tapes of the present invention to be larger than a single tape. That is, even if the size is smaller than the tapes, the plate portions of the tape partition plates can be bonded together and used as the same size as the lithographic printing plate. For example, as shown in FIG. 13, a tape partition plate having a size divided into two in advance may be prepared, and these may be bonded to form a tape partition plate of a required size, as shown in FIG. In this way, the tape partition plate may be prepared in advance in a four-divided size, and these tape partition plates may be bonded to form a tape partition plate of a required size. . Further, when the tape partition plate is smaller than the outer periphery of the tape, a tape partition plate of a necessary size may be configured by a connecting block as shown in FIG.

  The tapes will be described. The tapes referred to in the present invention indicate a belt-like shape that extends long with a width, and there are no particular restrictions on the length, width, winding diameter, etc. of the tapes as long as it is a disk shape, and the width is in the longitudinal direction. On the other hand, there is no problem even if the area is constant or thick or thin. For example, if the tape is rolled around a core such as a paper tube, the winding shape of the tape may be record winding, bobbin winding, or any other known winding shape. From the viewpoint of fixing the tapes and suppressing the telescoping phenomenon, the winding diameter of the tapes is preferably longer than the width of the tapes and is disc-shaped. Here, the winding diameter of the tape means a length obtained by subtracting the tape winding core diameter from the outer diameter of the tape.

In addition, the base material of the tapes may be any base material as long as it is a material that can be processed into a strip having a wide width and a long length. Or a multilayer structure etc. are mentioned.
Here, the paper used for the tapes may be any paper generally used for drawing, printing, packaging, etc., for example, kraft paper, bleached kraft paper, Nomex paper, crepe paper, flat paper, Japanese paper, high-quality paper Cardboard, corrugated cardboard, water-soluble paper, coated paper, thin paper, flat paper, liner paper, water-repellent paper, dust-free paper, and the like. The paper may be laminated with a resin film or impregnated with resin or the like.

The resin used for tapes refers to a thermoplastic resin or a thermosetting resin, but any resin that is generally used for tapes may be used. Examples of thermoplastic resins include polyethylene resin, polypropylene resin, polystyrene resin, methacrylic resin, polyvinyl chloride resin, polyamide resin, polycarbonate resin, polyethylene terephthalate resin, polybutylene terephthalate resin, and cellulose acetate resin. Examples include urea resins, melamine resins, xylene resins, phenol resins, unsaturated polyester resins, and the like, and examples thereof include single resins or copolymer resins thereof.
Examples of the cloth used for the tapes include synthetic fabrics such as polyester and polyethylene, and woven fabrics woven with natural fibers such as cotton, hemp, and silk, nonwoven fabrics, glass cloths, and soft cloths.

Tapes may also have an adhesive layer, and typical adhesives generally used for tapes are rubber-based, acrylic-based, vinyl ether-based, silicon-based, etc., based on the raw material used as the main composition. Is mentioned.
Here, in the case where the tapes have an adhesive layer, from the viewpoint of peeling of the tape partition plate of the present invention and the tapes, at least 10 of the area where the tape partitions are in contact with the tape partition plate. % Or more is preferably peel-treated, and from the viewpoint of facilitating the peelability, more preferably 30% or more of the area in contact with the tapes, more preferably the area in contact with the tapes. That is, 50% or more is peeled off.

In addition, the tapes are in a state in which a label shape punched into an arbitrary shape such as a rectangle, a circle, and other polygons having at least one adhesive layer is attached to the tapes. Also good. Further, the tapes may be subjected to surface treatment (corona treatment, peeling treatment, printing, etc.).
The package will be described.
The package of this invention means the package obtained using the partition plate for tapes of this invention. In other words, the tapes are fixed and pinched by using the tape dividers, so that the telescope phenomenon can be suppressed when the tapes are stored for a long period of time, and external shocks during transportation and storage are prevented. In addition to the above-mentioned advantages, if the release material is treated on the surface where the tape partition plate and the tape are in contact with each other, the effect of having the function of a release paper is exhibited.

Hereinafter, it will be described in detail with reference to the drawings.
FIG. 16 shows an example of a partition plate for tapes according to the present invention. The plate portion is a square flat plate, the tape fixing surface of the plate portion is a cylindrical convex portion, and the partition plate fixing surface is a cylindrical shape. It has a connecting hole.
Moreover, FIGS. 17-21 has shown an example of the method of packing several tapes using the partition plate for tapes shown in FIG.
First, as shown in FIG. 17, the inner side of the tape core is fixed by the convex portion of the tape partition plate.

  Next, as shown in FIG. 18, tape partition plates and tapes are alternately stacked. As shown in FIG. 19, the tapes laminated in this way may be fixed around the outer circumference of the laminated tapes with a binding band, a film, or the like. As shown in FIG. It may be accommodated in the like. In this case, the attaching position of the adhesive tape or the binding band is not particularly limited, but for example, it is preferable to fix each of the two long sides of the laminated tapes with an adhesive tape, a binding band, or the like. Further, the outer box is not limited to a box but may be a bag, or a flat plate may be disposed on at least one of the top and bottom surfaces of tapes laminated as shown in FIG. By storing the tapes thus laminated in an outer box or the like, the tapes are shielded from light and moisture-proof, and can maintain a constant quality for a long period of time. Further, by protecting the laminated tapes from the outside with an exterior box or the like, it is possible to prevent the tapes from being deformed or damaged by an external impact.

The present invention is not limited to the forms shown in FIGS. For example, the shape of the plate portion is not limited to a square flat plate, and a circular shape, a triangular shape, or any other shape may be used.
Further, as a method of laminating the partition plates for tapes and the tapes, the tapes and the partition plates for tapes may be alternately laminated as shown in FIG. 18, or the tapes as shown in FIG. One roll of tape may be sandwiched between two tape partition plates so that the partition plate fixing surfaces of the partition plate face each other. Further, the method for laminating the tapes is not particularly limited. For example, as described above, the tapes may be laminated so that the bottom surface is parallel, or the tapes and the bottom surface may be perpendicular as shown in FIG. May be laminated.

  The partition plate for tapes of the present invention laminates tapes, and when transporting and storing, the adhesive oozes out from the side of the tapes so that the single rolls adhere to each other, the telescope phenomenon occurs, and the physical properties of the tapes deteriorate. It prevents the deterioration of the product quality such as the collapse of the package and the damage of the tapes when transporting the tapes, but the tapes are not necessarily used in a stacked state. As shown in Fig. 24, even when tapes are transported only by a single volume, or when tapes are stored for a long time with a small amount (single volume to several volumes), the tapes are bonded to each other or telescope phenomenon. It has the effect of suppressing the occurrence of.
