Description

Technical Field

[0001] The present invention relates to an anti-counterfeiting seal that can prevent the contents of a container from being removed or replaced easily.

Background Art

[0002] Conventionally, in containers for foods and the like, an anti-counterfeiting seal is known, which is attached across the seal between the container body and the lid to prevent unauthorized opening and serves as a sealing mark. For example, Patent Document 1 discloses an anti-counterfeiting seal in which a plurality of cut lines having appropriate dimensions in the vertical and horizontal directions are provided on an extremely thin plastic film so as not to reach the outer peripheral edge, and cracks are generated in the cut lines by a peeling action to make it impossible to reattach.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

[0010] The anti-counterfeiting seal 1 according to the present invention (hereinafter also simply referred to as "the seal of the present invention") is used by being attached across the boundary between the container body and the lid. In this specification, the "container" is not particularly limited as long as it is a container having a container body and a lid, and examples include tubes, bottles, bottles, individual boxes, cans, and the like. The seal 1 of the present invention is particularly effective when used for a container (for example, a food tube) of a type that is opened by rotating the lid about the vertical axis with the opening of the container body facing upward. The material of the container is not particularly limited, and may be, for example, polyethylene terephthalate (PET), nylon, polypropylene (PP), glass, paper, metal, etc., and the container may have a single-layer structure or a multilayer structure.

[0011] The seal 1 of the present invention has a substantially rectangular shape that is vertically long when viewed from the front. In this specification, the "sub-rectangle" does not necessarily mean a strict rectangle, but may be a shape similar to a rectangle having at least a pair of long sides and a pair of short sides facing each other. Shapes with rounded corners such as those with R chamfers at the four corners or shapes such as an oval with slightly rounded long sides may also be included. From the viewpoint of preventing the seal from peeling off from the corners unintentionally during the manufacturing process or the distribution process, a shape with rounded corners at the four corners is preferable.

[0012] The material constituting the seal 1 of the present invention is not particularly limited, and various materials used as seal materials can be used. Examples include biaxially oriented polypropylene (ОPP) and polyethylene terephthalate (PET).

[0013] The length L of the seal 1 of the present invention is not particularly limited, and examples include 15 mm to 40 mm. The width W of the seal 1 of the present invention is not particularly limited, and examples include 8 mm to 20 mm.

[0014] Examples of the thickness of the seal 1 of the present invention include 40 μm to 70 μm. When the thickness of the seal is within the above range, it breaks when an attempt is made to illegally open the container, and it becomes possible to easily peel off the seal when an ordinary user opens the container. When the thickness of the seal is less than 40 μm, the strength of the seal becomes insufficient, and it becomes difficult for an ordinary user to peel off the seal. When the thickness of the seal exceeds 70 μm, the seal does not break when an attempt is made to illegally open the container, and it becomes difficult to open the container because the seal does not break when an ordinary user opens the container.

[0015] An adhesive is applied to the back surface of the seal 1 of the present invention. In this specification, the "adhesive" is not particularly limited, and various materials used for sticking seals can be used.

[0016] The adhesive strength can be appropriately set so that it is difficult to peel off the seal for the purpose of illegally opening the container, while it is easy for an ordinary user to peel off the seal.

[0017] In the seal 1 of the present invention, cut portions 11 extending inward from each of the substantially rectangular long sides of its outer peripheral edge are provided in two on each long side, and the cut portions 11 are arranged to be line-symmetric with respect to a straight line passing through the center of each short side of the substantially rectangular shape, or are arranged to be point-symmetric about the intersection of the straight line passing through the center of each short side of the substantially rectangular shape and the straight line passing through the center of each long side of the substantially rectangular shape. In this specification, the "cut portion" is not particularly limited as long as it serves as a starting point for the seal to break, and the cuts may be continuous or may be intermittent like perforations.

[0018] The cut portion 11 may extend in a direction perpendicular to the longitudinal direction of the substantially rectangular shape, or the left and right cut portions 11 may extend so as to form a U-shape or an inverted U-shape. Moreover, it is preferable that one of the two cut portions 11 provided on each long side of the substantially rectangular shape is located on the container body side and the other is located on the lid side. With such a configuration, when peeling the seal, the seal is likely to break starting from the cut portion, making it difficult to peel the seal for the purpose of illegally opening the container, while it becomes easy for the general user to peel the seal.

[0019] Examples of the length of the cut portion 11 include 5% to 30% of the length of the short side of the substantially rectangular shape (the width W of the seal 1 of the present invention), and 10% to 20% is preferable. When the length of the cut portion 11 is within the above range, when peeling the seal, the seal is likely to break starting from the cut portion, making it difficult to peel the seal for the purpose of illegally opening the container, while it becomes easy for the general user to peel the seal. When the length of the cut portion 11 is less than 5% of the length of the short side of the substantially rectangular shape, the seal does not break starting from the cut portion when peeling the seal, and it becomes easy to illegally open the container. When the length of the cut portion 11 exceeds 30% of the length of the short side of the substantially rectangular shape, the general user breaks it halfway when peeling the seal, making it difficult to peel. Note that the length of the cut portion 11 satisfies the above range not only when the cut portion 11 extends in a direction perpendicular to the longitudinal direction of the substantially rectangular shape, but also when the left and right cut portions 11 extend in a V-shape or an inverted V-shape.

[0020] The cut portion 11 preferably enters from a position 15% to 25% of the length of the long side of the substantially rectangular shape away from the center of each long side of the substantially rectangular shape in the vertical direction. With such a configuration, it is possible to easily attach the seal to the container by a labeler, and it is possible to provide an anti-counterfeiting seal that does not break or peel off during the manufacturing line of the product or during the transportation of the product.

[0021] Hereinafter, the present invention will be described more specifically with reference to examples, but the present invention is not limited to the following examples.
