BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrying tape used for carrying plastic bottles, paper packs, disposable diapers, toilet paper, and the like packed and packed.

[0002]

2. Description of the Related Art Conventionally, a tape used as a hand-held tape of this type is a tape having no pressure-sensitive adhesive layer, which is directly heat-sealed to an integrated package or used separately. A tape with an adhesive layer, or a tape with an adhesive layer, which is attached to a part of the adhesive layer with a separately molded backing paper or sponge to form a non-adhesive part and use it as a carrying tape There is also a tape or a tape which is formed by folding a part of the tape on the glue surface side and superposing the adhesives together to form a non-adhesive portion and using the non-adhesive portion as a tape for carrying. Recently, a hand-held tape in which an adhesive is partially coated and an adhesive portion and a non-adhesive portion are alternately provided has been devised.

[0003]

However, the tapes used as the conventional hand-held tapes require, for example, a non-adhesive tape which requires a separate heat-sealing device or a non-adhesive tape. In the case of an attached tape, the user must attach a separately prepared backing sheet or the like to the place to be the carrying part, or bend it and use it one by one. There is a problem that it cannot be easily used unless an auxiliary tool is used or some operation is performed.

On the other hand, one of the hand-held tapes designed to solve these problems, that is, a tape partially coated with an adhesive in the longitudinal direction of the base material (Japanese Utility Model Application Laid-Open No. 4-35516).
Can solve the above-mentioned problem, but when the adherend (stacked package etc.) is lifted by the non-adhesive part because the adhesive is intermittently coated, the intermittently coated small area Stress is concentrated on the adhesive portion, and as a result, the adhesive has a serious drawback in that it causes creep between the substrate and the adherend and easily peels off. In addition, the non-adhesive part is the base material itself, and there is a restriction that this base material must satisfy the carrying function in strength and elongation. It also has the disadvantage that the hand feel is sacrificed.

[0005] This invention is intended to solve the above-mentioned problems at once, and can be used as a carrying tape without any additional tools and without any additional work. What you can do,
In use, creep may occur between the adhesive layer and the base material or between the adhesive layer and the adherend (such as an integrated package),
It is an object of the present invention to provide a hand-held tape that does not allow the adherend to be dislodged or peeled off, and that the hand-held portion for carrying the adherend is easy to hold, is soft, and does not become difficult to handle. I do.

[0006]

A hand-held tape according to the present invention is provided on one side of a base material having sufficient strength and elongation to carry an adherend such as an integrated package. Non-adhesive layer composed of a printing layer or a flocking layer of a fixed length on this adhesive layer surface, while continuously providing an adhesive layer having an adhesive holding force sufficient to hang an adherend such as an object Are provided at regular intervals, and the base material has a breaking strength of 5 kg.
f / 19 mm or more, elongation under a 5 kg load is 20% or less, and the pressure-sensitive adhesive layer has a creep of 0 m when an adherend having a load of 5 kg or less is hung for 60 minutes at a temperature of 40 ° C. or less.
m. It is characterized by being composed of an adhesive having an adhesive holding power of m. In a preferred embodiment of the carrying tape according to the present invention, a release agent layer is provided on the surface of the substrate opposite to the surface on which the pressure-sensitive adhesive layer of the substrate is provided, and the substrate is laminated on itself or A tape-like or linear core material is interposed between the bodies in the longitudinal direction.

[0007]

The carrying tape in the present invention uses a substrate having a selected strength and elongation, and has a structure in which an adhesive layer is continuously provided over the entire length of one side of the substrate. Extremely safe against breakage, peeling and dropping during transportation. On the other hand, since the non-adhesive layer composed of the printing layer or the flocking layer is provided on the surface of the adhesive, the non-adhesive layer has a function as a strong hand-held portion without peeling. In addition, it has a hand-feeling function that is soft to the touch during carrying, and is soft and does not become hard, and can also have a function as a display object. In addition, the invented tape is extremely simple and easy to use for users who can carry the adherend simply by applying without any auxiliary equipment and without any extra work. Has functions.

That is, FIG. 1 is a perspective view showing a part of the tape of the present invention, wherein 1 is a base material, 2 is an adhesive layer, 3 is a non-adhesive layer, 4 is a back mold release agent layer, and 5 is It is a colored printing layer. In the drawing, L1 indicates the length of the non-adhesive layer 3, and L2 indicates the length of the adhesive layer 2 at the exposed portion. 2 to 5 are perspective views showing another embodiment of the present invention. FIG. 2 shows an example in which the base material 1 is a laminate (1a, 1b), and the non-adhesive layer 3 is a flocking layer 6. Fig. 3 is an example diagram in which a tape-shaped core material 7a is internally provided in the base material 1 and a foam print layer 8 is used in the layer 3 to be adhered. Fig. 4 is a diagram illustrating the base material 1 in the form of a laminate (1a, 1b). FIG. 5 shows an example in which a linear core material 7b is internally provided, and FIG. 5 shows an example in which the non-adhesive layer 3 is composed of a display print layer 9 displaying characters and the like. FIG. 6 is a perspective view showing an example of use of the carrying tape of the present invention.

Here, the base material 1 shown in FIGS. 1 to 6 has a strength and elongation sufficient for carrying and transporting the integrated package, that is, a breaking strength of 5 kgf / 19 mm or more, and an elongation at a large load of 5 kg of 20. %, Such as polyester film, polybutadiene terephthalate film,
A plastic film such as a high crystalline polyethylene film, a polyimide film, a strongly stretched polypropylene film, or a polyester fiber, a polypropylene fiber, a polyethylene fiber, an acrylic fiber, a nylon fiber, a polyimide fiber, a fiber such as a hemp, a staple, a rayon, or a cotton. A material appropriately selected from a knitted fabric, a nonwoven fabric made of polyester, polypropylene, polyethylene, acrylic, nylon, or polyimide resin or paper such as Japanese paper is preferably used. Furthermore, in order to maintain the strength as shown in FIGS. 2 and 4, these films, fabrics, nonwoven fabrics and papers may be appropriately combined and used as a laminate.

The base material 1 may be provided in the base material 1 itself as shown in FIG. 3 or in the laminates 1a and 1b as shown in FIG.
Tape-shaped core material 7 made of metal such as copper, brass, and aluminum
The strength of the base material 1 can be further reinforced by laminating, knitting, or weaving the a or the linear core material 7b therein.

The breaking strength of the substrate 1 is 5 kgf / 19
The reason why it is set to be not less than 5 mm is that there is a risk that the base material 1 may be broken during carrying while carrying it by hand with a breaking strength of 5 kgf / 19 mm or less.
The reason for the following is that, when the base material is stretched by 20% or more, the base material becomes thin due to the elongation due to the load, and the pain such as difficulty in getting into the hand is felt, and the adherend 10 hangs down due to the elongation of the base material. This is inconvenient and inappropriate.

Next, the pressure-sensitive adhesive layer 2 shown in FIGS. 1 to 6 is provided on one surface of the base material 1 by being continuously applied or transferred over the entire length of the base material. In consideration of the application, an adhesive is used, in particular, in consideration of the adhesive holding power. According to experiments performed by the inventor and the like, the adhesion holding force is such that the adherend 10 with a load of 5 kg is 60 ° C. at 40 ° C.
It is necessary for safety that the pressure-sensitive adhesive layer 2 has a creep of 0 mm under the condition that the adhesive layer 2 is hung for a minute. By the way, this is the above condition (5kg load at 40 ° C for 60 minutes)
And the adhesive layer 2 has a creep of 10 mm, 5 mm, and 2 m.
m, 0 mm, 4 samples (tape width 19 mm)
kg of the adherend 10 (attachment area 38 mm), and hang it outdoors at an outside temperature of 18 ° C. to 30 ° C. for 7 days day and night.
A hanging test was performed to see if 0 fell. As a result, the adhesive tape sample having a creep of 10 mm dropped the adherend 10 after 4 hours, the adhesive tape sample having a creep of 5 mm dropped the adherend 10 hours after 10 hours, and the adhesive tape sample having a creep of 2 mm caused the creep to grow to 10 mm in 7 days. However, it was confirmed by the experimental result that the adhesive tape sample having a creep of 0 mm did not show any abnormality even after 7 days in the state of the creep of 0 mm.

That is, regardless of the material of the adherend 10, the adhesive holding force of the adhesive is set to a temperature of 40 ° C. or less and a load of 5 kg.
In the following, keeping the creep at 0 mm is extremely important in this invention. The reason for this is that even when carrying by hand, it is necessary to consider the safety of drop prevention as long as the adherend 10 with a constant load is hung and carried, and as for the adhesive having a large creep in this point, as shown in a practical test, It is difficult to endure that role.

What is important in the present invention is that printing layers 5, 8, and 9 (FIGS. 1, 3, 4, and 5) or a fixed length are provided on the continuously provided pressure-sensitive adhesive layer 2 surface. The non-adhesive layer 3 composed of the flocking layer 6 (FIG. 2) made of short fibrous substance (pine) is provided at regular intervals. Here, the reason why the pressure-sensitive adhesive layer 2 is provided continuously over the entire length of the base material 1 is to increase the load area of the pressure-sensitive adhesive with respect to the load applied to the pressure-sensitive adhesive layer 2 at the time of use (at the time of carrying), and to distribute the stress. Another purpose is to provide cushioning to the hand-held portion 11 shown in FIG.

That is, as shown in FIG. 6, the carrying tape of the present invention comprises a carrying portion 11 and a sticking portion 12, and the adhesive layer 2 provided on the sticking portion 12 is It is composed of an adhesive having an adhesive holding power of creep 0 provided continuously over the entire length of one side. on the other hand,
The length of the carrying portion 11 differs depending on the intended use (L1) approximately 1
The non-adhesive layer 3 having a thickness of 00 mm to 500 mm is approximately 50 mm to 25 mm in the longitudinal direction on the surface of the continuously provided adhesive layer 2.
By being provided at a constant interval length (L2) of 0 mm,
Be composed.

Here, the non-adhesive layer 3 is formed by the printing layers 5, 8, 9 or the flocking layer 6. The printing layer is mainly composed of a transparent printing material or a coloring agent and a foaming agent if a binder is required. Transparent or colored printing layer 5
(FIGS. 1 and 4), a foam print layer 8 (FIG. 3), a display print layer 9 (FIG. 5) displaying desired characters, numbers, patterns, marks, and the like, or a print layer formed of a combination thereof. However, the pressure-sensitive adhesive layer 2 of the hand-held portion 11 must be able to be completely coated. The printing ink used to form these printing layers 5, 8, and 9 may be any of a water-soluble type and a solvent type as long as it is a printing ink capable of printing on the glue surface. The use of a solvent that dissolves the glue must be avoided. The use of the foam printing ink so that the finish becomes the foam print layer 8 (FIG. 3) is effective in making the handle 11 particularly comfortable to touch.

On the other hand, according to the present invention, the flocked layer 6 (FIG. 2) and the non-adhesive layer 3
The flocked layer 6 in this invention (FIG. 2)
Is made of nylon, polyester, acrylic, rayon, cotton, etc., having a thickness of 20d to 2d and a length of 1.0mm to 0.01mm.
A flocked layer using short fibers (pile) is preferable. The thickness and length of the short fiber can be appropriately selected depending on the intended use,
Those with a thickness of 20 d and a length of 1.0 mm or more are not preferred because they have a rough feel and poor tactile effect, and those with a thickness of 2 d or less and a length of 0.01 mm or less are close to powdery and thin non-adhesive layers. Is formed, and the desired texture cannot be achieved.

As described above, the non-adhesive layer 3 provided on the surface of the adhesive layer 2 at regular intervals and at a constant length can be easily adhered by the strong adhesive force of the adhesive layer 2 and can be applied under a load. Completely adheres without flaking. Since the pressure-sensitive adhesive layer 2 is provided continuously in the longitudinal direction of the base material 1 as described above, the load area under a load is large, and unstress dispersion can be achieved. In addition, the pressure-sensitive adhesive has a creep of 0 mm under a load of 5 kg or less. Since it is designed to have an adhesive holding force, it has an extremely stable hand-carrying force.

[0019]

As described above, the carrying tape of the present invention has a structure in which a base material having a selected high elongation is used and an adhesive layer is continuously provided on one side of the base material. As a result, the carrying portion does not stretch or break during carrying, and the adhesive surface cannot withstand the load and pulls the workpiece down. Has stable performance. In addition, since the non-adhesive layer composed of the printing layer or the flocking layer is provided on the adhesive surface, an essential effect as a tape for carrying, which enhances the feel of the carrying portion, is imparted to the carrying portion. In addition, the pressure-sensitive adhesive layer in the hand-held portion also functions as a cushion, and has an additional effect that the non-adhesive layer firmly adheres to the adhesive surface and does not peel off.
