Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sealing seal which is applied to a sealing portion of various containers, and which can maintain a sealed state and can be easily and accurately cut when opening the sealing portion.

[0002]

[Prior art]

 Generally, various containers are used in various industrial fields to store or store articles such as materials and products. This container is made of paper, cloth, wood, metal, glass, synthetic resin, or the like, and is three-dimensionally assembled into a cube or rectangular parallelepiped, prism, cylinder, pyramid, cone, or sphere. At least one surface of such a container is usually formed so that the container can be opened and closed or one of the two can be moved in and out of the container.

For example, in the external view of the container shown in FIG. 1, an insertion portion 2 connected to an opening / closing surface 1 corresponding to a lid of the container is inserted so as to be in contact with a side surface 3 of the container to form a container. In this case, the outer surface of the insertion portion 2 is brought into close contact with the inner surface of the container side surface 3 or the inner surface of the insertion portion 2 is brought into close contact with the outer surface of the container side surface 3 by an adhesive means such as glue to form a sealed portion. . Also, in consideration of the convenience of the operation of opening the container and taking out the contents, a perforated line is formed at the bending position of the insertion portion 2 and the opening / closing surface 1 or at a part or the entire surface of the container side surface 3. There is.

In order to open such a container, pressing force is usually applied with a finger, or the perforation is cut using a tool such as scissors or a knife, and then one surface is pushed open to open. However, in this type, it is necessary to cut the entire perforation line. In other words, if an attempt is made to forcibly open the container while the broken line is incompletely cut, the container surface will be broken irregularly in the middle of the perforation line, and the container will not be completely opened. May be difficult to remove.

In order to solve this problem, a sealing seal (hereinafter simply referred to as “sealing seal”) from the opening / closing surface 1 to the container side surface 3 without making the insertion portion 2 and the container side surface 3 in FIG. ) Is affixed. This type is an easy-to-use container sealing means which can easily push up the open / close surface to be in the opened state by cutting only the sealing portion with a knife or the like.

[0006] However, even with such a sealing seal, it is necessary to cut the entirety of the sealing by using a tip of a claw or using a knife. Also, if this type of seal is to be forcibly cut, unless the seal material has a fibrous property oriented in a certain direction, or unless the material is easily broken, such as thin paper, etc. When a force, i.e., a pushing or pulling force, is applied, cutting is started in a random direction from the position where the cutting starts, making it difficult to cut completely completely and often peeling off the entire seal. If a fibrous or directional material is used as the sealing material, the cost will increase, and if thin paper is used, it will be easily destroyed by a slight external force and the sealing state will be broken, and the sealing function will be exhibited. become unable.

In some cases, the sealing seal is provided with perforated lines to facilitate the cutting of the seal. However, only one perforated line is provided. In this case, the seal can be cut more easily than a sealing seal having no perforation line. However, the cutting of the seal is performed by the pressing force or the pulling force for cutting the seal being concentrated on one end of the perforation line. It is necessary to attach a seal so that the line of sight is parallel to the bent part of the insertion part 2. If this position and direction are shifted obliquely, the cutting start position will not be at one end of the perforated line, The same thing happens, or the cutting operation is stopped in the middle of the perforation line, and it is cut in a random direction by the way of applying force from that position, making it impossible to cut the sealing seal easily and accurately May be.

[0008]

[Problems to be solved by the invention]

 In view of this situation, the present invention solves the problem of providing a sealing seal that is attached to a sealing portion of a container, has a sufficient sealing function, and can be easily, accurately and completely cut when opening the sealing portion. Should be an issue.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a sealing seal having a plurality of perforation lines. The perforation lines are formed in the direction in which the seal is cut, and more preferably, the plurality of perforation lines are parallel to each other or cross each other near the center of the seal. The size and form of the seal itself are arbitrary, and the material can be appropriately selected, but a synthetic resin film or a thin metal plate is desirable. By affixing the sealing seal provided with the perforation line to the sealing of the container, the sealing function can be easily and accurately cut with the same container sealing function as before. The perforation line is a line in which a broken line is partially cut (perforated) into a line, and is a processing form for facilitating the cutting of the surface by applying a force thereto.

[0010]

[Embodiment of the invention]

 The sealing seal of the present invention has a plurality of perforation lines. This perforation line is produced in the same manner by a conventionally known perforation forming means (perforation needle). However, as shown in FIG. It is made to stretch. The number of perforation lines is required to be at least two, and more preferably three. The plurality of perforation lines may be formed, for example, in parallel with each other as shown in FIG. 2a, or may be formed so as to intersect each other at substantially the center of the sealing seal as shown in FIG. 2b.

The interval between the perforation lines can be arbitrarily set depending on the material, thickness, size, etc. of the sealing seal, the size of the container to which the seal is attached, and the like. If the maximum width including the perforation line is too large, a state similar to that having only one perforation line may be obtained, and it may be difficult to cut the perforation line easily, accurately, and completely. The maximum interval between the perforation lines is, for example, a sealing material made of a synthetic resin film such as polyethylene, polypropylene, or polyethylene terephthalate, a length in the major axis direction of about 2 cm, and a length in the minor axis direction. In the case of a sealing seal having a length of about 1.5 cm, it is about 2 to 5 mm, more preferably about 2 to 3 mm. If necessary, the number of perforations may be increased within the maximum interval. Further, in the case of a sealing seal for applying to a large container having a side of 1 m or more, the size of the sealing itself naturally increases, and the maximum interval between perforation lines is determined by the sealing function of the sealing. It can be set arbitrarily in consideration of the strength of the seal and the ease of cutting, but it is sufficient to make the width of about 5 to 30% of the length in the long axis direction of the seal concerned easy.

As the material of the sealing seal of the present invention, any material such as paper, cloth, metal, synthetic resin and the like can be used. Among them, synthetic resins such as polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polyvinyl chloride, and the like, and metals such as aluminum, which have strength in terms of container sealing function, are preferable. This is molded into a film having an appropriate thickness, the perforation line is formed by a known perforation forming means, and an adhesive or a pressure-sensitive adhesive is applied to the back surface to produce a sealing seal of the present invention. The cut portion and the non-cut portion of the perforation line may be at equal intervals or at different intervals, but preferably have a regular shape. In a form in which a plurality of perforation lines are parallel to each other, it is preferable that the cut portions and the non-cut portions of the adjacent perforation lines are alternately formed. The sealing seal of the present invention is used by attaching an appropriate number of them to the sealing part of the container.

[0013]

[Action]

 Since a plurality of perforation lines are formed in the sealing seal of the present invention, an external force (a pushing force or a pulling force) is applied to an arbitrary position between the perforation lines at one end of the seal when the seal is cut. With the addition of, the cutting operation is easily started from any one of the plurality of perforation lines, and the seal is completely separated in the cut state as it is. Also, even if the cutting direction is shifted during the cutting of the perforation line and the perforation line deviates, the other perforation line adjacent to the perforation line is continuously cut, so that the perforation line is accurately and completely cut. it can.

[0014]

【Example】

 Adhesive paste is applied to one side of a transparent polyethylene terephthalate film with a thickness of 50 μm, pasted on a release liner, and cut with an elliptical blade 20 mm long in the long axis direction and 17 mm long in the short axis direction. In addition, three perforations passing through the center of the major axis of the elliptical shape and both sides of a 1 mm width from the center in total and forming three perforations parallel to the major axis are formed. A sealing seal was made (see FIG. 2a). This seal was attached from the upper lid to the side of the box as a sealing seal for the upper lid of a cubic cardboard box having a side of 15 cm. Next, when a portion of the upper lid surface or the upper portion of the side of the box near the position where the seal was attached was lightly pulled outward of the box, the perforation line was cut easily, accurately, and completely.

[0015]

[Effect of the invention]

 The sealing seal of the present invention has an excellent container sealing function and has a plurality of perforations so that the seal can be easily, accurately and completely cut at the time of opening.
