<<<Manufacturing method of tape member package A>>>
The method for manufacturing the tape member package A includes a film coating step of coating a plurality of stacked roll-shaped tape members 210 with a film tubular body 100 made of a heat-shrinkable film 110, and a film coating step after the film coating step. and a heat shrinking step of heat shrinking the cylindrical body 100 .

As a representative form of the roll-shaped tape member 210, as shown in FIG. 1(1), there is a tape member formed by winding a long adhesive tape 211 around a winding core 212 in a roll shape. . However, this is only an example, and the roll-shaped tape member 210 may not have the winding core 212 .

In addition, "stacking" in the present invention indicates stacking a plurality of roll-shaped tape members 210 such that the roll axial directions are substantially aligned, as shown in FIG. 1(2). Further, in the present invention, a stack of tape members 210 is referred to as a stack of tapes 200 .

The type of roll-shaped tape member 210 in the present invention is not particularly limited, and includes all available roll-shaped adhesive tape members.

The roll-shaped tape member 210 may be, for example, a baseless tape, cellophane tape, paper tape, cloth tape, metal tape, self-bonding tape, Although it can be classified into protective tape, curing tape, etc., any of these can be used.

The height (tape width) of the roll-shaped tape member 210 and the outer diameter of the roll are not particularly limited, and can be appropriately set according to the application.

The plurality of roll-shaped tape members 210 forming the tape stack 200 may have different heights and different roll outer diameters. However, if the roll outer diameters of the plurality of roll-shaped tape members 210 differ greatly, it may be difficult to pack them at the same time, so it is preferable that the roll outer diameters are uniform to some extent.

The number of roll-shaped tape members 210 included in the tape stack 200 is not particularly limited, and can be designed as appropriate.

The roll-shaped tape member 210 may have an outer shape other than a circular shape (for example, a polygonal shape, etc.).

In the stack of tapes 200, a film, cardboard, or the like is provided between the members of the plurality of roll-shaped tape members 210, or on the upper and lower surfaces of the stack of tapes 200, so that the adhesive tapes 211 of the roll-shaped tape members 210 adhere to each other. , may be prevented from interfering with other members.

In the present invention, the heat-shrinkable film is generally not particularly limited as long as it is heat-shrinkable, and refers to a film that can be shrunk by 60 to 70% by heat treatment.

<<Film coating process>>
The film covering step is a step of covering at least the side surface (surface in the roll outer peripheral direction) of the tape stack 200 with a heat-shrinkable film, and includes at least a film placement step and a film bonding step.

In the film arranging step, a heat-shrinkable first film 111 and a heat-shrinkable second film 112 are placed along the roll outer periphery of the stacked tape body 200 (the plurality of stacked roll-shaped tape members 210). Allocate

Specifically, as shown in FIG. 2(1), first, a first film end portion 111a, which is one end portion of a square-shaped first film 111, and a belt-like (long length having two parallel sides) A film 110 is prepared by joining a second film end portion 112a, which is one end portion of a second film 112 having a shape). The other end of the first film 111 is referred to as a first film end 111b, and the other end of the second film 112 is referred to as a second film end 112b.

Next, as shown in FIGS. 2(1) and 2(2), the direction in which the first film 111 and the second film 112 are arranged and the roll axial direction of the tape stack 200 (rolled tape member 210) , and are perpendicular to each other.

Next, as shown in FIG. 2(3), the film 110 (the first film 111 and the second film 112) is wound on the tape stack 200. Next, as shown in FIG.

Through the above steps, the film 110 (the first film 111 and the second film 112) is arranged along the roll side surface of the stack of tapes 200, and the roll side of the stack of tapes 200 is the first film 111. and covered with the second film 112 .

Next, in the film joining step, as shown in FIGS. 3(1) and 3(2), the first film end 111b and the second film end 112b are joined, and the roll side surface of the tape stack 200 is A film tube 100 is formed to cover the .

A gap may or may not exist between the film tube 100 and the tape stack 200 .

Here, when the tensile elongation of the second film 112 in the direction corresponding to the circumferential direction of the film tube 100 (the circumferential direction of the roll of the roll tape member 210) is defined as the tensile elongation TE _MD2 , the tensile elongation TE _MD2 becomes 150% or less. By configuring the second film 112 in this way, it is possible to improve the ease of unpacking the tape member package A obtained. The tensile elongation TE _MD2 is preferably 130% or less and 100% or less. Although the lower limit of the tensile elongation TE _MD2 is not particularly limited, it may be 40%, 60%, 80%, or the like.

In addition, when the tensile elongation of the second film 112 in the direction corresponding to the tube axis direction of the film tube 100 (the roll axis direction of the roll tape member 210) is the tensile elongation _TECD2 , the tensile elongation TE The ratio of _MD2 to tensile elongation TE _CD2 (TE _MD2 /TE _CD2 ) is preferably 0.20 or less, more preferably 0.15 or less. Although the lower limit of this ratio is not particularly limited, it may be 0.05, 0.075, 0.10, or the like.

Similarly, when the tensile elongation of the first film 111 in the direction corresponding to the circumferential direction of the film tube 100 is defined as the tensile elongation TE _MD1 , the tensile elongation TE _MD1 is 300% or less. It is preferably 250% or less, more preferably 250% or less. Although the lower limit of the tensile elongation TE _MD1 is not particularly limited, it may be 100%, 125%, 150%, or the like.

Further, when the tensile elongation of the first film 111 in the direction corresponding to the cylinder axis direction of the film tubular body 100 is the tensile elongation TE _CD1 , the ratio of the tensile elongation TE _MD1 to the tensile elongation TE _CD1 ( TE _MD1 /TE _CD1 ) is preferably 0.40 or less, more preferably 0.30 or less. Although the lower limit of this ratio is not particularly limited, it may be 0.15, 0.20, or the like.

Furthermore, the ratio (TE _MD1 /TE _MD2 ) between the tensile elongation TE _MD1 of the first film 111 and the tensile elongation TE _MD2 of the second film 112 is preferably 1.0 to 3.0. 0.5 to 2.5 is more preferred.

In addition, the ratio (TE _CD1 /TE _CD2 ) of the tensile elongation TE _CD1 of the first film 111 and the tensile elongation TE _CD2 of the second film 112 is preferably 0.2 to 1.0. 0.4 to 0.8 is more preferred.

In order to achieve such a tensile elongation, the film 110 is arranged so that the circumferential direction of the film tube 100 and the MD direction of the second film 112 (MD direction of the first film 111) are aligned. It is preferable to arrange

The tensile elongation of the first film 111 and the second film 112 can be appropriately adjusted by changing the material and thickness of the film, the presence or absence of stretching, the degree of stretching, and the like.

The first film 111 and the second film 112 are usually films made of a resin material. The resin material is not particularly limited, and may be a resin material commonly used as a heat-shrinkable film, such as polyolefin resin, polystyrene resin, or polyester resin. The resin material is preferably polyolefin, more preferably polyethylene. Polyethylene generally includes low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear low-density polyethylene, and the like, and polyethylene in the present invention may be any of them.

From the viewpoint of improving bonding easiness, it is preferable that the first film 111 and the second film 112 are made of the same resin material. The same resin material means that the constituent monomers are the same.

The first film 111 and/or the second film 112 may be a single layer film or a multilayer film, and can be selected as appropriate.

Here, regarding the first film 111 and the second film 112, the lengths in the direction coinciding with the roll circumferential direction of the roll-shaped tape member 210 are defined as _L1 and _L2 , which coincide with the roll axial direction of the roll-shaped tape member 210. Let the lengths in the directions be W ₁ and W ₂ and the thicknesses be T ₁ and T ₂ (see FIG. 2).

L ₁ and L ₂ , and W ₁ and W ₂ can be appropriately designed according to the circumference and height of tape stack 200 .

The second film 112 forms an unpacking band 113 of the tape member package A, as will be described later. Therefore, in this embodiment, _L2 is set to be shorter than _L1 . More specifically, L ₁ :L ₂ is preferably 3:1 to 40:1, more preferably 5:1 to 30:1, and 7:1 to 20:1. is particularly preferred. By adjusting _L2 in this manner, the band width of the unpacking band 113 can be adjusted.

_W2 may be greater than _W1 . With such a configuration, as shown in FIG. 3(2), a part of the unpacking band 113 can be protruded from the film tube 100 to form a grip portion 115. As shown in FIG. By forming such a grip portion 115, it is possible to improve unpacking easiness.

W ₁ is preferably greater than the height of tape stack 200 . With such a configuration, as shown in FIG. It is possible to form a lower room portion 116b. By forming the upper room portion 116a, a part of the upper surface of the stacked tape body 200 is covered with the upper room portion 116a in the heat shrinking process. Similarly, by forming the lower room portion 116b, a part of the lower surface of the tape stack 200 is covered with the lower room portion 116b in the heat shrinking process. As a result, after the heat shrinking process, the upper surface and/or the lower surface of the stack of tapes 200 are restrained by the film 110, and the binding of the plurality of roll-shaped tape members 210 can be enhanced.

T ₁ and T ₂ are preferably 10 to 150 μm, more preferably 20 to 100 μm, in order to increase the strength and transparency of the tape member package A as an exterior.

Moreover, from the viewpoint of improving ease of unpacking, _T2 is preferably larger than _T1 . For example, T ₂ −T ₁ is preferably 5 μm or more, 10 μm or more, or 15 μm or more. In this case, the upper limit of T ₂ -T ₁ is, for example, 50 μm, 40 μm or 30 μm.

When the first film end portion 111a and the second film end portion 112a are joined, normally, as shown in FIGS. It is formed. Similarly, when the first film end portion 111b and the second film end portion 112b are joined together, the joint region 114b is formed.

The joint region 114a and the joint region 114b include the joint interface of the dissimilar members, and thus are regions where breakage is likely to occur, and function as a break line in the tape member package A. As shown in FIG. The size and shape of the bonding regions (bonding region 114a and bonding region 114b) can be appropriately designed according to the application.

Normally, the joint region 114a and the joint region 114b are formed continuously from the upper end to the lower end of the film tube 100 as shown in FIGS. 2 and 3, but are not limited to this. For example, the bonding region 114a and the bonding region 114b may be formed discontinuously.

Also, in joining the first film end portion 111a and the second film end portion 112a, the overlapping method of the first film 111 and the second film 112 can be appropriately changed.

For example, as shown in FIG. 4(1), the inner surface of the first film end 111a and the inner surface of the second film end 112a are overlapped and joined so that the joint region 114a protrudes from the film surface. good too.

Alternatively, as shown in FIG. 4(2), the inner surface of the first film end portion 111a and the outer surface of the second film end portion 112a may be overlapped and joined.

Similarly, the outer surface of the first film end portion 111a and the inner surface of the second film end portion 112a may be overlapped and joined, or the outer surface of the first film end portion 111a and the second film end portion 112a may be joined together. You may overlap and join an outer surface. Furthermore, bonding may be performed in which the bonding region 114a becomes more complicated.

Further, as shown in FIG. 4(3), the first film end 111a and the second film end 112b are separated from each other so that the extreme ends of the first film end 111a and/or the second film end 112a are not joined. may be joined together. In other words, in the joining of the first film end portion 111a and the second film end portion 112a, the surplus area (the first film surplus area 111c and/or the second film surplus area 112c) that protrudes from the joining area 114a. may be formed.

From the viewpoint of cost reduction, it is preferable to use a bonding method that minimizes the formation of surplus regions as much as possible. Note that, in the present invention, such surplus areas may also be treated as being included in the joining area.

The bonding between the first film edge 111a and the second film edge 112a may be bonding with an adhesive, or physical bonding such as stitching or three-dimensional meshing. Bonding by heat sealing is preferable in that it is easy to obtain the above. Incidentally, a specific joining method by thermal fusion is not particularly limited, but a heat sealing method, an impulse sealing method, an ultrasonic sealing method, and the like can be exemplified.

When the first film end portion 111a and the second film end portion 112a are joined by heat-sealing, the first film end portion 111a and/or the second film end portion 112a are heated to a softening point or higher. There is no particular limitation as long as it is a method of contacting or crimping.

The bonding between the first film end portion 111b and the second film end portion 112b can also be carried out in the same manner as described above.

When the films are heat-sealed together, the excessive regions may be cut off by heat at the same time.

It should be noted that when the first film 111 and the second film 112 are joined together, a joining region and a surplus region are formed. The sum of the length L ₁ and the length L ₂ of the second film 112 does not simply match. Therefore, the length L ₁ of the first film 111 (the length L ₂ of the second film 112) when configuring the film tube 100 is the length L ₁ of the first film 111 as a raw material (the length L 1 of the second film 112 length L ₂ ) minus the width of the joint region and the surplus region. However, if the width of the joining region and the surplus region is sufficiently narrow with respect to the length L ₁ of the first film 111 (the length L ₂ of the second film 112), the length L of the first film 111 in the raw material ₁ (the length L ₂ of the second film 112) and the length L ₁ (the length L ₂ of the second film 112) of the first film 111 in the film tube 100 may be treated as equivalent. .

Here, as described above, the first film 111 is a rectangular film, and the second film 112 is a belt-like (long shape having two parallel sides) film, thereby increasing the strength of the film tubular body 100. can be easily formed. However, the shape of the first film 111 and the shape of the second film 112 are not particularly limited as long as the film tube 100 can be formed by joining the ends of the first film 111 and the second film 112 . More specifically, the outer edges of the first film 111 and/or the second film 112 may have a shape consisting only of straight lines, a shape consisting only of curved lines, or a shape including straight lines and curved lines.

As an example, a configuration in which the second film 112 is elliptical will be described with reference to FIG.

First, the first film end portion 111a and the second film end portion 112a are overlapped and joined to form the film 110 having the joint region 114a (FIG. 5(1)). Next, after the film 110 is wound on the tape stack 200, the first film end portion 111b and the second film end portion 112b are overlapped and joined to form a joint region 114b. In this way, the film tube 100 is formed from the first film 111 and the second film 112, covers the side surface of the tape stack 200, and has the unpacking band 113 (FIG. 5(2)). .

The first film 111 and the second film 112 may have a partially hollowed shape as long as there is no problem in strength.

The first film 111 and the second film 112 may be transparent films or colored films.

Here, in the above description, in the film coating process, the case where the film bonding process is performed after the film placement process is performed has been described, but the film coating process is not limited to this.

For example, in the film joining process, the film tube 100 may be formed as follows.

First, the film 110 is formed by joining the second film end portion 112a and the first film end portion 111a with the first film 111 wound around the tape stack 200 . Next, the first film end portion 111b and the second film end portion 112b are joined to form the film tubular body 100. Next, as shown in FIG.

Moreover, as described below, the film placement step may be performed after the film bonding step is performed.

First, as a film joining step, the two ends of the first film 111 and the second film 112 (the first film end 111a and the second film end 112a, and the first film end 111b and the second film end The portion 112b) is joined to form the film tube 100. FIG. Next, as a film placement step, the tape stack 200 is inserted from the opening of the film tube 100 so that the roll side surface of the tape stack 200 is covered with the first film 111 and the second film 112. do.

Thus, it is understood that the film placement step and the film bonding step can be performed in any order.

From the viewpoint of improving the ease of manufacturing the tape member package A and the processing accuracy in each process, the film 110 having the first film end 111a and the second film end 112a joined is prepared in advance. 110 is wound around the stack of tapes 200 to perform a film arrangement step, and a film joining step joins the first film end portion 111b and the second film end portion 112b to form a cylindrical film covering the stack of tapes 200. Forming 100 is preferred.

When forming the film tube 100, the two ends of the first film 111 and the second film 112 may be joined at the same time.

Here, normally, the physical properties of the first film 111 and the second film 112 are designed not to change significantly before and after the film tube 100 is formed. should have Therefore, considering the form in which the film tube 100 covers the tape stack 200 without gaps, the film tube 100 is formed while stretching the first film 111 and the second film 112 in the film coating step. good too.

<<Thermal contraction process>>
In the heat shrinking step, as shown in FIG. 6, the film tube 100 is heated while the side surface of the tape stack 200 is covered with the film tube 100 (the first film 111 and the second film 112). The tape member package A is manufactured by shrinking.

The heating means and heating conditions (heating temperature, heating time) are not particularly limited as long as the entire film 110 (the first film 111 and the second film 112) can be thermally shrunk to the required amount.

In the tape member package A obtained through the heat shrinking process, the second film 112 functions as the unpacking band 113 . That is, by pulling the unpacking band 113 in the axial direction of the stack of tapes 200, the side surface of the tubular film 100 is opened and the roll tape member 210 can be easily taken out.

<<Other processes>>
The method of manufacturing the tape member package A includes, as other steps, a step of cutting off the surplus region existing in the vicinity of the joint region, and the surface of the tape member package A (the film tube 100) having pictures, letters, unevenness, etc. and a step of inserting another member (for example, a product display sticker or a paper member) between the film tube 100 and the tape stack 200 .

In addition, a member that passes through the axis of the stack of tapes 200 (a member that penetrates the hollow portion of the roll center of the plurality of roll-shaped tape members 210) is arranged, and the stack of tapes 200 is substantially fixed. Each step may be performed after making sure that
