Description

Technical Field

[0001] The present invention relates to a sealing label having a tamper-evident function and a container with a sealing label attached thereto.

Background Art

[0002] A sealing label for sealing a container or box that houses a product, which prevents unauthorized opening and tampering or mischief with the contents, is disclosed in Patent Document 1.

[0003] The sealing label of Patent Document 1 has a strip-shaped cutting area formed on a label base material, which includes a horizontal cutting line and an oblique cutting line. This sealing label is attached to a container with the upper part of the label above the cutting area adhered to the lid and the lower part of the label below the cutting area adhered to the container body. Therefore, when the lid is rotated clockwise or counterclockwise with respect to the container body, the sealing label breaks along the cutting area. As a result, it is possible to easily determine visually whether the lid has been opened.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the container to which the sealing label of Patent Document 1 is attached is premised on the outer diameter of the lid portion to which the upper part of the label is attached and the outer diameter of the container body portion to which the lower part of the label is attached being the same. Therefore, in the case of a frustum-shaped shoulder whose outer diameter increases as the container portion to which the lower part of the label is attached moves away from the lid, wrinkles or unbonded portions may occur in the lower part of the label attached to the shoulder.

[0006] Furthermore, narrow, elongated, rectangular sealing labels are commonly known. Such elongated labels can be neatly and wrinkle-free attached to the shoulder of a truncated cone-shaped container, even when their lower end is attached to the aforementioned truncated cone. However, if the outer surface of the lid has anti-slip vertical grooves, sufficient contact area and adhesive strength may not be obtained between the sealing label and the lid, potentially causing the sealing label to easily peel off.

[0007] Therefore, the present invention aims to provide a sealing label that can securely attach the lower part of the label to a frustoconical container portion, and that can attach the upper part of the label with the necessary adhesive force to a lid having vertical grooves for anti-slip purposes, and to provide a container equipped with such a sealing label. [Means for solving the problem]

[0008] To achieve the above objective, a sealing label according to one embodiment of the present invention is A sealing label (100) comprising a first region (I) located in the first quadrant, a second region (II) located in the second quadrant, a third region (III) located in the third quadrant, and a fourth region (IV) located in the fourth quadrant, demarcated by a vertical axis (Y) and a horizontal axis (X), Between the first region (I) and the second region (II), an upper cut (13) is formed along the vertical axis (Y) from the upper edge (11) to the lower edge (12) of the sealing label (100). Between the third region (III) and the fourth region (IV), a lower cut (14) is formed along the vertical axis (Y) from the lower edge (12) to the upper edge (11) of the sealing label (100). Between the second region (II) and the third region (III), a left-hand notch (17) is formed along the horizontal axis (X) from the left edge (15) to the right edge (16) of the sealing label (100). Between the fourth region (IV) and the first region (I), a right-hand cut (18) is formed along the horizontal axis (X) from the right edge (16) to the left edge (15) of the sealing label (100). The distance (H1) from the horizontal axis (X) to the upper edge (11) of the sealing label (100) is greater than the distance (H2) from the horizontal axis (X) to the lower edge (12) of the sealing label (100).

[0009] A container relating to one embodiment of the present invention is Starting from the bottom and moving upwards, the container body (210) consists of a torso (211), a shoulder (212), and a neck (213) having male threads (214) on its outer surface, A screw-type cover (220) having a female thread (221) that screws into the male thread (214), A container with a sealing label, comprising the above-mentioned sealing label (100), The sealing label (100) is characterized in that the first region (I) and the second region (II) are adhered to the lid (220), and the third region (III) and the fourth region (IV) are adhered to the shoulder portion (212) of the container body (210). [Effects of the Invention]

[0010] In the sealing label according to the above embodiment, an upper cut is formed between the first region I and the second region II, so the label can be easily folded in the middle. Also, the area of ​​the first region I and the second region II of the label is large. Therefore, the necessary adhesive force is ensured between the label and the lid. A lower cut is formed between the third region III and the fourth region IV of the label, and a left cut and a right cut are formed between the first region I and the second region II, and between the third region III and the fourth region IV. As a result, the label deforms along two different three-dimensional curved surfaces, the outer surface shape of the lid and the outer surface shape of the shoulder, ensuring the necessary adhesive force is ensured between the container body and lid and the label.

Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments of the sealing label and the container with the sealing label according to the present invention will be described.

[0013] [A: Sealing Label] FIG. 1 shows the front of a sealing label (hereinafter simply referred to as "label") 100 according to an embodiment.

[0014] The label 100 is a sheet made of paper, a plastic film, or a metal film, or a composite sheet in which a plurality of sheets are laminated, and an adhesive layer is provided on the back surface as will be described later.

[0015] The label 100 of the embodiment has an overall substantially rectangular contour. The rectangle may be any of a square, a vertically long rectangle, or a horizontally long rectangle.

[0016] Label 100 is divided into four regions by the vertical axis Y and the horizontal axis X. The four regions consist of the first region I in the first quadrant, the second region II in the second quadrant, the third region III in the third quadrant, and the fourth region IV in the fourth quadrant.

[0017] As shown in the diagram, the vertical axis Y is a line that divides label 100 symmetrically. The horizontal axis X is located below horizontal axis X', which is exactly halfway between the top and bottom ends of label 100. Therefore, the height H1 of the first region I and the second region II is greater than the height H2 of the third region III and the fourth region IV.

[0018] Between the first region I and the second region II, an upper cut 13 is formed, extending along the vertical axis Y from the upper edge 11 to the lower edge 12 of the label 100. Between the third region III and the fourth region IV, a lower cut 14 is formed, extending along the vertical axis Y from the lower edge 12 to the upper edge of the label 100. As shown in the figure, the depth D1 of the upper cut 13 is greater than the depth D2 of the lower cut 14.

[0019] Between the second region II and the third region III, a left notch 17 is formed along the horizontal axis X, extending from the left edge 15 to the right edge 16 of the label 100. Between the fourth region IV and the first region I, a right notch 18 is formed along the horizontal axis X, extending from the right edge 16 to the left edge 15 of the label 100.

[0020] It is preferable to form cutting lines extending inward from the edges at the top, bottom, left, and right corners of the first region I to the fourth region IV. The cutting lines may be a single continuous cutting line, multiple perforations formed by short cutting lines spaced at regular intervals, or multiple holes spaced at regular intervals.

[0021] For example, in the upper right corner 21 of the first region I, a cutting line 22 is formed that extends diagonally from the edge of the upper right corner 21 toward the center of the first region I. In the upper left corner 23 of the second region II, a cutting line 24 is formed that extends diagonally from the edge of the upper left corner 23 toward the center of the second region II. In the lower left corner 25 of the third region III, a cutting line 26 is formed that extends diagonally from the edge of the lower left corner 25 toward the center of the third region III. In the lower right corner 27 of the fourth region IV, a cutting line 28 is formed that extends diagonally from the edge of the lower right corner 27 toward the center of the fourth region IV.

[0022] Similarly, in the first region I to the fourth region IV, it is preferable to form cutting lines extending inward from the edge at the entrance corners of the cuts 13, 14, 17, and 18. The cutting lines may be a single continuous cutting line, multiple perforations with short cutting lines spaced at regular intervals, or multiple holes spaced at regular intervals.

[0023] For example, in this embodiment, a diagonal cutting line 43 is formed from the upper left corner 41 of the first region I (right corner of the entrance) 41 and the upper right corner 42 of the second region II (left corner of the entrance), which are opposite each other across the entrance of the upper cut 13, toward the center of the first region I, and a diagonal cutting line 44 is formed from the upper right corner 42 of the second region II toward the center of the second region II. It is.

[0024] On either side of the entrance to the lower cut 14, at the lower right corner (left corner of the entrance) 51 of the third region III and the lower left corner (right corner of the entrance) 52 of the fourth region IV, a diagonal cutting line 53 is formed from the lower right corner 51 of the third region III toward the center of the third region III, and a diagonal cutting line 54 is formed from the lower left corner 52 of the fourth region IV toward the center of the fourth region IV.

[0025] On either side of the entrance of the left cut 17, at the lower left corner (upper corner of the entrance) 61 of the second region II and the upper left corner (lower corner of the entrance) 62 of the third region III, a diagonal cutting line 63 is formed from the lower left corner 61 of the second region II toward the center of the second region II, and a diagonal cutting line 64 is formed from the upper left corner 62 of the third region III toward the center of the third region III.

[0026] On either side of the entrance to the right cut 18, at the upper right corner (lower entrance corner) 71 of the fourth region IV and the lower right corner (lower entrance corner) 72 of the first region I, a diagonal cutting line 73 is formed from the upper right corner 71 of the fourth region IV toward the center of the fourth region IV, and a diagonal cutting line 74 is formed from the lower right corner 72 of the first region I toward the center of the first region I.

[0027] In the embodiment, a cutting line 19 is formed along the horizontal axis X between the left cut 17 and the right cut 18, and between the upper first region I and the second region II and the lower third region III and the fourth region IV. In the embodiment, it is preferable that the cutting line 19 includes, at least in part, a fracture portion that extends in a direction that intersects the horizontal axis (X) diagonally or substantially perpendicularly. In the embodiment, the cutting line 19 has the shape of alternating downward-convex U-shapes and upward-convex inverted U-shapes. The cutting line 19 may be a single continuous cutting line, a plurality of perforations formed by short cutting lines spaced at regular intervals, or a plurality of holes spaced at regular intervals.

[0028] As shown in Figure 2, adhesive 91 is applied to the back surface 90 of the label 100. The adhesive 91 may be applied to the entire back surface of the label 100, but an intermediate area including the cutting line 19, for example, an area 94 located between the boundary lines 92 and 93 located above and below the horizontal axis X, may be left unadhesive and designated as an unadhesive area.

[0029] On the surface 95 of the label 100, letters, special shapes, or patterns (for example, the words "Unopened" as shown in Figure 3) may be provided in the area where the cutting line 19 is formed or in the non-adhesive area.

[0030] [B: Container with sealing label] A container 200 equipped with a sealing label 100 is shown in Figure 3.

[0031] The container 200 has a container body 210 and a lid 220. The container body 210 is made of, for example, plastic, glass, or metal. The lid 220 is made of plastic or metal.

[0032] The container body 210 integrally comprises, from bottom to top, a body portion 211 with a substantially constant outer diameter for containing the contents, a frustoconical shoulder portion 212 with an outer diameter that gradually decreases towards the top, and a neck portion 213 with an opening for loading and unloading the contents, wherein the outer diameter of the neck portion 213 is smaller than the outer diameter of the shoulder portion 211. The shoulder portion 212 may be a frustoconical shape including a conical surface that is convex inward or a frustoconical shape including a conical surface that is convex outward.

[0033] As shown in Figure 4, an external thread (male thread) 214 is integrally formed on the outer circumferential surface of the neck portion 213. As shown in Figure 5, an internal thread (female thread) 221 is formed on the inner circumferential surface of the lid 220, having a size and shape that allows it to be screwed into the male thread 214 formed on the neck portion 213 of the container body 210.

[0034] On the outer circumferential surface of the lid 220, flat surface portions 222 are arranged in a circumferential direction, and corner portions (protrusions) 223 are formed between adjacent surface portions 222 in the circumferential direction, thereby forming a circumferential anti-slip surface 224. In this embodiment, 25 surface portions 222 have an angle difference of 14.4 degrees (=360 degrees / 25 portions) between adjacent surfaces.

[0035] After the contents (for example, tablets or powder in the case of a medicine container) are placed in the container body 210 of the container 200 configured in this way, the lid 220 is attached to the neck portion 213 of the container body 210. Then, the label 100 described above is affixed.

[0036] At this time, the label 100 has its upper first region I and second region II attached to the outer surface of the lid 220, and its lower third region III and fourth region IV attached to the shoulder portion 212 of the container body 210, with the area 94 without adhesive located in the gap between the lid 220 and the shoulder portion 212.

[0037] As shown in Figure 3, the outer surface of the lid 220 has alternating flat portions 222 and corner portions 223, but an upper cut 13 is formed between the first region I and the second region II, so the label 100 can be easily bent in the middle. In addition, the area of ​​the first region I and the second region II of the label 100 is larger. Therefore, even if there is a poorly adhering area near the corner portion 223, the necessary adhesive strength is ensured between the label and the lid 220.

[0038] On the other hand, the shoulder portion 212 of the container body 210 has a frustoconical shape different from the outer circumference shape of the lid 220, but a lower cut 14 is formed between the third region III and the fourth region IV at the bottom of the label, and a left cut 17 and a right cut 18 are formed between the first region I and the second region II at the top of the label and the third region III and the fourth region IV at the bottom of the label. As a result, the label 100 deforms along two different three-dimensional curved surfaces, the outer surface shape of the lid and the outer surface shape of the shoulder, ensuring the necessary adhesive force between the container body 210, the lid 220, and the label 100.

[0039] Therefore, during storage or transport of the container 200 containing the contents, the label 100 will not peel off from the container 200 due to contact with other objects or the stiffness of the label itself.

[0040] When the contents are first removed from the container 200 provided to the market, the user rotates the lid 220 counterclockwise. This causes a shear force to act on the label 100 between the first and second regions I and II at the top of the label and the third and fourth regions III and IV at the bottom of the label. As shown in Figure 6, if a cutting line 19 is formed, the portion of the label with the cutting line 19 will easily break. As illustrated, the intermediate region 94 with the cutting line 19 is torn to the extent that the printed characters, etc., on that intermediate region 94 are illegible. Therefore, even if the lid 220 is rotated counterclockwise to return the torn upper and lower parts of the label to their original positions, the printed characters, etc., remain illegible, and the user can be sure that the container has been opened.

[0041] Furthermore, since the label 100 has diagonal cutting lines 22, 24, 26, 28, 43, 44, 53, 54, 63, 64, 73, and 74 formed at each corner of the first region I to the fourth region IV, if someone tries to peel off the attached label 100, the label will be destroyed at the cutting lines, making it easy to confirm that someone has tried to peel off the label 100.

[0042] [C: Other embodiments] The labels and containers of the embodiments described above can be modified in various ways.

[0043] For example, the outline of label 100 does not have to be a square or rectangle, but may be a trapezoid (a trapezoid where the upper base is smaller than the lower base, or a trapezoid where the upper base is larger than the lower base), a circle, or an ellipse (including an ellipse or oval shape with a major axis in the vertical direction and a minor axis in the horizontal direction, or an ellipse or oval shape with a major axis in the horizontal direction and a minor axis in the vertical direction).

[0044] For example, an embodiment of a circular label is shown in Figure 7. In this embodiment of the circular label, the horizontal axis X is located below the center of the circular label, and as a result, the vertical size (height H1) of the first region I and the second region II is larger than the vertical size (height H2) of the third region III and the fourth watershed IV. Therefore, the same effects and advantages as the label of the embodiment described above can be obtained.

[0045] In label 100, the cutting line 19 formed between the upper first region I and second region II and the lower third region III and fourth region IV is not limited to the shape shown in Figure 1, and may include at least a portion of a fractured portion 20 extending in a direction intersecting the horizontal axis (X). For example, as shown in Figure 8, it may be a cutting shape in which upper and lower cutting line portions extending horizontally and diagonal cutting portions connecting these upper and lower cutting portions are repeated horizontally [Figure 8(a)], diagonal cutting portions are arranged in a straight line [Figure 8(b)], or "X" shaped cutting portions are repeated horizontally [Figure 8(c)].

[0046] As shown in Figure 9, the anti-slip surface 225 formed on the outer surface of the container lid 220 may be constructed by forming grooves (recesses) 226 extending in the vertical direction at regular intervals in the circumferential direction. In this embodiment, the area in contact between the first region I and the second region II at the top of the label and the outer surface of the lid 220 is further reduced. However, since the area of ​​the first region I and the second region II at the top of the label is larger than the area of ​​the third region III and the fourth region IV at the bottom of the label, the necessary adhesive force can be obtained between the label 100 and the lid 220.

[0047] Although an embodiment in which the lower part of the label is attached to the shoulder portion between the torso and neck portion has been described above, the above-mentioned sealing label can also be applied to containers without shoulder portions, and such embodiments are also included within the scope of the present invention.

[0048] Furthermore, the container body is not limited to containers where the outer diameter of the body is larger than the outer diameter of the lid. The sealing label described above can also be applied to containers where the outer diameter of the lid and the outer diameter of the body are the same, or to containers where the outer diameter of the lid is larger than the outer diameter of the body. Such embodiments are also included within the scope of the present invention. [Explanation of Symbols]
