Description

[Technical Field]

[0001] The present invention relates to a spontaneously removable and environmentally friendly container label filament, a container label, a container, and a method for applying a container label. [Background technology]

[0002] Container labels are used on product containers as a section for writing product names and details. As disclosed in Non-Patent Document 1, in order to recycle PET bottles with high quality, it is necessary to separate the container body from the container label. Conventionally, the container label has been separated and removed mainly by wind power, taking advantage of the weight difference between the PET bottle and the container label. However, as the weight of PET bottles themselves has become lighter, the weight difference between the container label and the container label has become smaller, making separation by wind power more difficult. Therefore, in order to recycle PET bottles with high quality more efficiently, it is becoming increasingly important to remove the container label.

[0003] However, when discarding PET bottles, the container body and the container label must be separated before disposal, but it is not easy to peel the container label off the container body. As a result, PET bottles are often discarded without removing the container label from the container body, resulting in insufficient separation and adverse effects on the environment.

[0004] In response to this, for example, Patent Document 1 discloses a container label in which a strip-shaped container label is wound around and the end adjacent portion is superimposed on the start adjacent portion and adhered. Even with the invention of Patent Document 1, it is not easy to find the end adjacent portion and peel the container label from the end adjacent portion, and there are cases where the containers are not sufficiently separated. Meanwhile, Patent Document 2 discloses a container label for PET bottle containers in which an uneven portion is provided on the upper edge of the container label to be affixed to the PET bottle container.

[0007] Even if the upper edge of the container label attached to a PET bottle is provided with a concave-convex portion, it is not easy to hook the convex portion of the container label with your fingers and peel it off, which makes separating the PET bottle body and the container label cumbersome and causes problems of insufficient separation.In addition, the main component of conventional container labels is difficult to decompose in nature, and they are often littered or washed into ocean currents, causing adverse effects on the environment. In wild animals, they can accidentally ingest them or become entangled in them, causing adverse effects such as starvation and injury.

[0008] For this reason, there is a demand for a container label that can be easily peeled off from a PET bottle container and that allows the container body and the container label to be easily separated. [Means for solving the problem]

[0009] The filament according to the present invention is This filament is for container labels and is characterized by being spirally wound around the outer peripheral surface of a container body that contains the contents, with the starting end and the end being fixed to adjacent starting end adjacent portions and end adjacent portions, respectively, to form fixed portions.

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

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

[0028] Fig. 2 is a schematic perspective view showing a state in which a container label 13 is wrapped around the outer peripheral surface of a container body 11 according to the present invention. Fig. 3 is a schematic perspective view showing a state in which a container label 13 is wrapped around the outer peripheral surface of a modified container body 11 according to the present invention. Fig. 4 is a schematic front view (A) and a cross-sectional view (B) showing a state in which a container label 13 is wrapped around the outer peripheral surface of a container body 11 according to the present invention. Note that Figs. 2, 3, and 4 omit illustration of a display unit 60 provided on the surface of the container label 13 to display the product name and product details.

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

[0030] Container 10 has a cap 12 on top of container body 11, which seals the contents contained in container body 11. Also, approximately in the center of the outer circumferential surface of container body 11, a container label 13 is provided which displays the product name and product details.

[0031] The container body 11 is made of PET resin. The container body 11 is not limited to PET resin as long as it can maintain a shape that allows the contents to be contained therein, and may be made of, for example, a thermoplastic resin, a thermosetting resin, or glass. Thermoplastic resins may include PE, HDPE, PP, PVC, PS, PVAc, PUR, PTFE, ABS, and PLA (polylactic acid resin). Thermosetting resins may include epoxy resin, phenol resin, SMC, BMC, urea resin, melamine resin, diallyl phthalate resin, silicone resin, and vinyl ester resin.

[0032] The container label 13 is located approximately in the center of the outer peripheral surface of the container body 11, and has a filament 20, a start-end adjacent portion 30, a terminal-end adjacent portion 40, and a fixed portion 50. The container label 13 is formed by spirally winding the filament 20 so that it is in close contact with the outer peripheral surface of the container body 11, and fixing the start end 23 and the terminal end 24 of the filament 20 to the start-end adjacent portion 30 and the terminal-end adjacent portion 40 of the adjacent filament 20, respectively, to form the fixed portion 50.

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

[0034] When displaying the product name and product details on the container label 13, a display section 60 is provided on the surface of the container label 13. The product name and product details can be displayed on the display section 60 by printing using a method such as water pressure transfer, pad printing, or transfer printing.

[0035] The filament 20 is a wire having a substantially circular cross section. However, the filament 20 is not limited to a wire, and may be a string or strip, as long as it can be tightly wound spirally around and fixed to the outer peripheral surface of the container body 11. The filament 20 may be made of a resin such as ABS, ASA, PC-ABS, PLA, urethane, PP, PET, TPE, PC, PA, or PBAT. It is more preferable that the filament 20 be made of a biodegradable resin such as PLA, because the filament 20 will naturally decompose even if released into the environment.

[0036] The filament 20 may be wound spirally around the outer circumferential surface of the container body 11 in close contact with the outer circumferential surface, and may be, for example, PLA NFC PEAL WHITE manufactured by XYZprinting Co., Ltd., with a wire diameter of 1.75 mm.

[0037] 5A shows a front view of the container body 11 according to the present invention, and FIG. 5B shows an enlarged view of the adjacent portion 30 of the filament 20 for the container label 13 according to the present invention. The adjacent portion 40 of the filament 20 has the same shape as the adjacent portion 30 of the filament 20.

[0038] The fixed 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. Fixing may be performed by heating the filament 20 to weld it, or by bonding it with an adhesive.

[0039] For example, a Geevorks plastic welding machine model LH50 can be used to heat and weld the filament 20. If the heating part of the plastic welding machine used for welding is V-shaped, this is preferable because it makes it easier to make the area of ​​the fixed part 50 small.

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

[0041] First, the PLA resin filament 20 is cut from a reel around which the filament 20 is wound to a predetermined length corresponding to the width of the container label 13 to be attached to the container body 11. Next, the cut filament 20 is spirally wound and fixed at a predetermined position on the outer circumferential surface of the container body 11. At this time, care must be taken to ensure that the filament 20 is wound so as to be in close contact with the container body 11. Then, the starting end 23 and the ending end 24 are welded to the starting end adjacent portion 30 and the ending end adjacent portion 40 of the adjacent filament 20 using a plastic welding machine, respectively, to form the fixed portion 50. Note that when welding the filament 20, care must be taken not to heat and damage the container body 11 with the heating portion of the plastic welding machine.

[0042] Thereafter, if necessary, the product name and product details can be printed on the outer surface of the container label 13 to form a display section 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 the state of removing the container label 13 from the container body 11. Fig. 6(A) is a schematic diagram showing the state immediately after the adjacent-to-start portion 30 of the filament 20 has been removed from the container body 11, Fig. 6(B) is a schematic diagram showing the state of the filament 20 being removed, and Fig. 6(C) is a schematic diagram showing the state of the filament 20 completely removed from the container body 11.

[0044] To remove the container label 13, first, use your fingers to release the fastening portion 50 of the adjacent start end portion 30 of the filament 20 from its fastening and pull it upward (see FIG. 5(A)). Then, the filament 20 will spontaneously come off the container body 11 due to its elastic force (see FIG. 5(B)). Finally, release the fastening portion 50 of the adjacent end portion 40 of the filament 20 from its fastening, and the filament 20 will be completely removed from the container body 11 (see FIG. 5(C)).

[0045] Thereafter, the container body 11 and the container label 13 (filament 20) are separated and collected separately.

[0046] Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Industrial Applicability]

[0047] With the container label 13 filament 20, container label 13, container 10, and method of attaching container label 13 according to the present invention, when the two fastening portions 50 of container label 13 are released from the container body 11, the label spontaneously peels off, making it possible to easily separate container label 13 for PET bottle containers. Furthermore, if a biodegradable resin is used for container label 13, it is possible to minimize the adverse impact on the environment even if container label 13 is released into the environment.
