Description

Technical Field

[0001] The present invention relates to a filament for a container label that can be spontaneously removed and is environmentally friendly, a container label, a container, and a method for attaching the container label.

Background Art

[0002] Container labels are used on product containers as parts for entering product names and product details. As disclosed in Non-Patent Document 1, in order to perform high-quality recycling of PET bottles, it is necessary to separate the container body and the container label. Conventionally, the container label mainly uses the weight difference between the PET bottle and the container label to separate and remove the container body and the container label mainly by wind power. However, since the weight of the PET bottle itself has been reduced and the weight difference from the container label has become smaller, it has become difficult to separate by wind power. Therefore, in order to perform more efficient and high-quality recycling, the importance of peeling off the container label has increased.

[0003] However, when disposing of PET bottles, although it is necessary to separate and discard the container body and the container label, it is not easy to peel the container label from the container body. Therefore, it may be discarded without peeling the container label from the container body, and sufficient separation may not be performed, which may have an adverse impact on the environment.

[0004] On the other hand, for example, Patent Document 1 discloses a container label in which a strip-shaped container label is wound around and the terminal adjacent portion is overlapped and adhered on the start-end adjacent portion. Even in the invention according to Patent Document 1, it is not easy to find the terminal adjacent portion and peel the container label from the terminal adjacent portion, and sufficient separation may not be performed in some cases. On the other hand, Patent Document 2 discloses a container label for a PET bottle container in which uneven portions are provided on the upper side of the container label attached to the PET bottle container.

Embodiments for Carrying Out the Invention

[0026] First, an embodiment of the container 10 according to the present invention will be described with reference to FIG. 1. FIG. 1 is a schematic perspective view seen from the upper right of the container 10.

[0027] The container 10 is for containing contents. The contents may be a liquid or a powder. The container 10 according to the present invention includes a container body 11, a cap 12, and a container label 13.

[0028] FIG. 2 is a schematic perspective view showing a state in which the container label 13 is wound around the outer peripheral surface of the container body 11 according to the present invention. FIG. 3 is a schematic perspective view showing a state in which the container label 13 is wound around the outer peripheral surface of the container body 11 of a modified form according to the present invention. Further, FIG. 4 is a schematic front view (A) and a cross-sectional view (B) showing a state in which the container label 13 is wound around the outer peripheral surface of the container body 11 according to the present invention. In addition, in FIGS. 2, 3, and 4, illustration of a display portion 60 provided on the surface of the container label 13 for displaying a product name and product details is omitted.

[0029] The container body 11 (hereinafter also referred to as "body 11") contains the contents. The container body 11 is a hollow columnar body having a substantially circular cross-section perpendicular to the extending direction. As shown in FIG. 3, it may be a hollow columnar body having a substantially polygonal cross-section perpendicular to the extending direction.

[0030] The container 10 includes a cap 12 at the upper part of the container body 11 and encloses the contents contained in the container body 11. Further, at a substantially central portion of the outer peripheral surface of the container body 11, a container label 13 for displaying a product name and product details is provided.

[0031] The container body 11 is made of PET resin. The container body 11 only needs to maintain a shape capable of accommodating the contents, and is not limited to PET resin. For example, it may be a thermoplastic resin, a thermosetting resin, or glass. If it is a thermoplastic resin, it may be PE, HDPE, PP, PVC, PS, PVAc, PUR, PTFE, ABS, PLA (polylactic acid resin), etc. If it is a thermosetting resin, it may be an epoxy resin, a phenol resin, SMC, BMC, a urea resin, a melamine resin, a diallyl phthalate resin, a silicone resin, or a vinyl ester resin.

[0032] The container label 13 is located at substantially the center of the outer peripheral surface of the container body 11 and has a filament 20, a start-end adjacent portion 30, an end-end adjacent portion 40, and a fixing portion 50. The container label 13 is spirally wound around the outer peripheral surface of the container body 11 so that the filament 20 is in close contact with it, and the start end 23 and the end end 24 of the filament 20 are fixed to the start-end adjacent portion 30 and the end-end adjacent portion 40 of the adjacent filaments 20 respectively, and are formed as the fixing portion 50.

[0033] In the embodiment according to the present invention, the upper end of the illustrated filament 20 is taken as the start end 23, and the lower end and the end end 24, but the upper end may be the end end 24 and the lower end may be the start end 23.

[0034] When displaying the product name and product details on the container label 13, a display portion 60 is provided on the surface of the container label 13. To display the product name and product details on the display portion 60, it is also possible to print using methods such as water pressure transfer, pad printing, transfer printing, etc.

[0035] The filament 20 is a strip-shaped body with a substantially circular cross-section. However, the filament 20 only needs to be able to be spirally wound and fixed in close contact with the outer peripheral surface of the container body 11, and is not limited to a strip-shaped body, and may be a string-shaped body or a belt-shaped body. The filament 20 may be, for example, a resin such as ABS, ASA, PC-ABS, PLA, urethane, PP, PET, TPE, PC, PA, PBAT, etc. In addition, if the filament 20 is a biodegradable resin such as PLA, it is more preferable because the filament 20 will be naturally decomposed even if it flows out into the natural world.

[0036] As the filament 20, it only needs to be able to be spirally wound in close contact with the outer peripheral surface of the container body 11. For example, it may be PLA NFC PEAL WHITE with a wire diameter of 1.75 mm from XYZprinting.

[0037] Next, FIG. 5 shows a front view (A) of the container body 11 according to the present invention and an enlarged view (B) of the start-end adjacent portion 30 of the filament 20 for the container label 13 of the present invention. Note that the end-end adjacent portion 40 of the filament 20 has the same form as the start-end adjacent portion 30 of the filament 20.

[0038] The fixing portion 50 is formed by fixing the start end 23 and the end end 24 of the filament 20 to the start-end adjacent portion 30 and the end-end adjacent portion 40 of the adjacent filament 20, respectively. The fixing may be performed by heating and welding the filament 20, or by using an adhesive for adhesion.

[0039] To heat and weld the filament 20, for example, a plastic welder model number LH50 manufactured by Geevorks can be used. It is preferable that the heating portion of the plastic welder used for welding is V-shaped, as it facilitates making the fixing portion 50 have a small area.

[0040] Next, a method for attaching the container label 13 to the container body 11 will be described.

[0041] First, cut the PLA resin filament 20 from the reel around which the filament 20 is wound to a predetermined length according to the width of the container label 13 attached to the container body 11. Next, wind and fix the cut filament 20 spirally around a predetermined position on the outer peripheral surface of the container body 11. At this time, pay attention to winding the filament 20 so as to be in close contact with the container body 11. Then, weld the start end 23 and the end end 24 respectively to the start-end adjacent part 30 and the end-end adjacent part 40 of the adjacent filament 20 using a plastic welder, and set each as the fixing part 50. Note that when welding the filament 20, it is necessary to be careful not to damage the container body 11 by heating it with the heating part of the plastic welder.

[0042] After that, if necessary, print the product name and product details on the outer surface of the container label 13 to make it the display part 60.

[0043] Next, a method for removing the container label 13 from the container body 11 will be described. FIG. 6 is a schematic diagram showing a state of removing the container label 13 from the container body 11. FIG. 6(A) is a schematic diagram showing the state immediately after removing the start-end adjacent part 30 of the filament 20 from the container body 11, FIG. 6(B) is a schematic diagram showing a state in which the filament 20 is being removed, and FIG. 6(C) is a schematic diagram showing a state in which the filament 20 has been completely removed from the container body 11.

[0044] To remove the container label 13, first, use a finger to release the fixing part 50 of the start-end adjacent part 30 of the filament 20 from the fixing and pull it upward (see FIG. 6 (A)). Then, due to the elastic force, the filament 20 will spontaneously come off the container body 11 (see FIG. 6 (B)). Finally, when the fixing part 50 of the end-end adjacent part 40 of the filament 20 is released from the fixing, the filament 20 will be completely removed from the container body 11 (see FIG. 6 (C)).

[0045] After that, separate the container body 11 and the container label 13 (filament 20), and collect them separately.

[0046] As described above, the present invention has been described using embodiments. However, the technical scope of the present invention is not limited to the scope described in the above embodiments. It is obvious to those skilled in the art that various changes or improvements can be made to the above embodiments. It is clear from the description of the claims that forms with such changes or improvements can also be included in the technical scope of the present invention.

Industrial Applicability

[0047] In the case of the filament 20 of the container label 13, the container label 13, the container 10, and the method of attaching the container label 13 according to the present invention, when the two fixing portions 50 of the container label 13 are detached from the fixing to the container body 11, it spontaneously peels off, and it is possible to easily separate the container label 13 for PET bottle containers. Further, when a biodegradable resin is used for the container label 13, even if the container label 13 flows out into the natural world, it is possible to minimize the adverse effects on the natural world.
