Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an end structure of an adhesive tape used for sealing a package by attaching an adhesive tape.

[0002]

[Prior art]

 When the package is sealed, the use of adhesive tape is often used for its easy workability.

In this case, workability at the time of opening the package after transporting the package to a predetermined destination is also important. In particular, recently, under the enforcement of the Recycling Law, the recycling rate of used packaging cases can be improved. It is expected to be used, and it is required to completely remove the adhesive tape from the packaging case when opening.

Conventionally, in order to improve the opening workability of a package sealed with an adhesive tape, as shown in (a) of FIG. 3, the adhesive tape is attached to the adhesive surface at the terminal portion 3'of the adhesive tape 2 '. By sticking the non-adhesive piece a'and using the terminal portion 3'as a picking margin, the terminal portion 3'of the adhesive tape 2'is folded back as shown in FIG. In addition, as shown in FIG. 3C, a perforation b is inserted along the center of the width of the adhesive tape 2 ', and the adhesive tape is cut twice with the perforation b as a boundary. It is publicly known that the peeling force is reduced by separating into two parts.

[0005]

[Problems to be solved by the device]

 However, in the end structure of the adhesive tape shown in FIG. 3 (a) and FIG. 3 (b), there is a non-adhesive portion which is not adhered to the adhered surface at the terminal portion of the adhesive tape. As shown in Fig. 4, when a frictional force acts on this non-adhesive portion during transportation of the package, a tensile component τ that opens the adhesive interface is generated depending on the direction of the frictional force. Peeling progresses from the tape end in a chained manner, the effective length of the sealing which is responsible for the sealing force of the package is reduced, and finally unintentional opening during transportation may be caused.

On the other hand, in the end structure of the adhesive tape shown in FIG. 3C, chain-like peeling from the tape end can be avoided. However, the external force acting on the package during transportation is complicated, and depending on the vibration during the transportation and the load condition, the external force acts in a direction perpendicular to the perforation b and the perforation b during transportation is affected. There is concern about accidental opening by incision.

An object of the present invention is to ensure a stable sealing of a package during transportation, and to easily open the package after transportation, which is an end structure of an adhesive tape. To provide.

[0008]

[Means for Solving the Problems]

 The end structure of the sticking tape of the present invention is such that a plucking palm portion is formed near at least one end of the adhesive tape stuck to the surface to be stuck, and is adjacent to the piling portion. The present invention is characterized in that the end of the existing adhesive tape is adhered to the surface to be adhered.

[0009]

[Action]

 Since there is a tape adhering part adjacent to the palm part, the palm part can be stably fixed and held on the surface to be adhered, and chain separation from the tape end starting from the palm part is well prevented. it can.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. In FIG. 1, reference numeral 1 is a packaging case such as a corrugated box. Reference numeral 2 denotes a single-sided adhesive tape that is attached to seal the packaging case, and is attached to both sides of the case from the seam of the outer lid of the packaging case. Reference numeral 3 is a gas palm section provided in at least one end of the adhesive tape in the width direction. Reference numeral 4 denotes an end portion of the adhesive tape which is adjacent to the gas palm section 3, and is adhered to the packaging case 2. The length L ₄ of the end portion 4 of the adhesive tape is not particularly limited as long as it can maintain the stable sealing property of the package and can be easily peeled off at the time of opening, and the tape width and the surface of the adherend. It is determined according to the condition and the properties of the adhesive.

In the above description, the height of the chisel portion 3 is appropriately set to a height that is suitable for picking up the chisel portion and peeling off the adhesive tape, and that does not hinder the transportation of the package. It

In the above description, the length L ₅ of the adhesive tape portion 5 from the edge 11 on the side surface of the packaging case to the joint portion 3 is the tape width, the adhesive force per tape unit area, It is determined according to the required sealing force, the surface condition of the adherend and the properties of the adhesive. In the case of simple packaging or the like that requires a low sealing force, it can be used in the mode shown in FIG.

In the above-mentioned end structure of the adhesive tape, since the end portion 4 of the adhesive tape is present adjacent to the palm part 3, the palm part 3 has a frictional force during transportation of the package. Even if an external force such as the above acts, due to the adhesive force of the end portion 4 of the sticking tape, peeling of the gas palm section 3 can be prevented well, and (a) of FIG. 3 and (b) of FIG. The chain peeling at the end of the adhesive tape in the conventional example shown in (3) can be eliminated well, and stable sealing performance can be guaranteed. Further, unlike the conventional example shown in FIG. 3C, there is no perforation along the center of the tape width, and accidental opening due to perforation during transportation can be eliminated.

In this case, the sealing force is given by the sticking tape portion 5 from the edge 11 on the side surface of the packaging case to the joint portion 3, and the end portion of the sticking tape adjacent to the joint portion 3 Since 4 does not substantially participate in the sealing force, it is not necessary to increase the length of the end portion 4 of the adhesive tape, and the opening workability can be sufficiently ensured.

In addition to the above packaging, the present invention can also be used for temporary fixing, for example, temporary fixing of a refrigerator door, or binding for transporting a long object.

[0016]

As described above, if the packaging tape is sealed by the adhesive tape having the end structure of the present invention, as described above, the stable sealing property during transportation of the packaging body can be guaranteed, and Since the opening can be performed with a comparatively small force, the opening work is easy, and the adhesive tape can be completely peeled off from the package, it is convenient for the reuse of the packaging case.
