Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a stopper for sealing an opening of a bag-like container (hereinafter, referred to as “container”) made of a flexible material made of a plastic film, paper, or a multilayer material thereof.

[0002]

[Prior art]

 It is common practice to sell and store product materials in containers made of flexible materials made of plastic film, paper or their multilayer materials. For example, food materials such as snacks are put in for sale.

In this case, a so-called zipper is provided at the opening of the container in order to prevent the contents from being solidified by absorbing moisture in the outside air after being opened, and to prevent the smell of the contents from being diffused into the outside air. There was a case where a seal member called was provided. The zipper is excellent in keeping the air tightness, but it is not suitable for installation depending on the material of the container, and has the disadvantage that it costs more.

Until now, as shown in FIG. 1, a stopper 1 made of a hard material is attached to the opening of the container B by applying an adhesive to one side, and the stopper is bent in the direction of the arrow to open the container. Some parts are sealed to prevent the contents from absorbing moisture in the outside air and solidifying even after the contents are once opened, and to prevent the odor of the contents from escaping to the outside.

As shown in FIG. 2, such a stopper is a resin material portion in which a metal wire is embedded in the center of both ends of the long side of a band-shaped stopper body 3 made of a resin material. There is a stop made of one provided with 5. Such a stopper is supplied to a factory or the like that manufactures a product using the stopper in a rolled state, and then cut into a certain length at the factory or the like to form one stopper. It is completed as a stopper and mounted on the product container. In this type of stopper, when the container is opened and stored until reopening, the opening of the container is folded, and then the stopper is pressed down with a finger to fix the bent portion of the bending opening to secure the container. Sealing has been performed.

[0006]

[Problems to be solved by the invention]

 However, in the conventional stoppers, the cut surface of the resin material and the metal wire is initially integrated, but since the metal wires are embedded at both ends of the long side of the band-shaped stopper, the resin material in this portion is The metal wire tends to protrude and protrude from the edge of the stopper. When using a stopper to close the container, in order to increase the sealing effect, bend the opening of the container and then press firmly with a finger on the resin material stopper with the metal wire embedded in it, or the stopper itself. Was necessary. At that time, the protruding metal wire could damage the packaging material of the container or hurt human fingers.

[0007]

[Means for Solving the Problems]

 The present invention has been embodied in order to solve the above-mentioned problems, and the invention according to claim 1 is for opening a bag-like container made of a flexible material such as plastic film, paper or a multilayer material thereof. A stopper for attaching to the opening, wherein the stopper main body has a longer side than the long side of the opening portion, and the main body is made of a material containing a resin material, and extends along the longer side of the main body. The axial center of the metal wire is at least about 1.0 mm inward from the outermost edge of the fastener body.

According to a second aspect of the present invention, there is provided a fastener in which the axis of the metal wire is 1.5 mm to W / 3 (W: width of the fastener) from the outermost edge of the fastener body. I do. According to a third aspect of the present invention, the metal wire is a ferrous metal wire having a diameter of 0.2 to 1.0 mm.

As the resin material, vinyl chloride, polyethylene, or a mixture thereof can be used, but other resin materials may be used. The stopper according to the present invention can be used by bonding it to a bag-like container with an adhesive or the like. This bag-shaped container can be used for any kind of contents, but is suitable for those having a hygroscopic property, those which are likely to deteriorate due to contact with air, and those which volatilize odors. For example, in addition to seasonings such as sugar and salt, confectionery, palatable foods such as regular coffee and instant coffee, and food such as laver, feed such as pet food, etc. Can be adapted for reopening.

[0010]

Embodiment

 As shown in the cross section in FIG. 3, the stopper 1 'according to the present invention is a metal wire whose axis is located at a distance S from the outermost edge at both ends of a main body 3' made of a resin material and having a width W. 4 'is buried.

FIG. 4 shows an embodiment of a product in which the stopper according to the present invention is attached to a bag-like container. Attach the stopper to the opening of the bag-shaped container, bend the stopper around the periphery of the container opening, and then directly touch the tip of the stopper with another container or the finger or hand of another person to prevent damage. Covering with a piece of adhesive tape or the like prevents exposure of the fasteners, which can improve the quality of the fasteners during transportation and during handling at stores.

When the stopper according to the present invention is used, as shown in FIG. 5, even after the amount of the contents is reduced, the stopper is folded in the direction of the arrow with the stopper still attached to the opening of the container. This makes it possible to safely repeat the container opening in accordance with the amount of the contents and to reliably seal the container opening.

[0013]

【Example】

 Next, one embodiment of the stopper 1 'according to the present invention is shown in FIG. A fastener having a metal wire embedded in a fastener made of a resin material containing vinyl chloride and / or polyethylene is shown.

As shown in FIG. 6, a stopper body 3 ′ made of a resin material having a length of 120 mm, a width of 10 mm, and a thickness of 0.7 mm is provided on an edge portion of the stopper body along two long sides. Of diameter 0. A 47 mm metal wire 4 ′ is embedded in parallel so that each axis is located 2.0 mm inside from the outermost edge of the long side.

FIG. 7 shows a form in which the stopper according to the present invention is delivered to a factory or the like to be attached to the opening of the bag-shaped container. As shown in FIG. 7, the stoppers are wound on a reel and delivered, and then cut into predetermined lengths one by one at the time of use.

[0016]

[Effect of the invention]

 By using the stopper according to the present invention, when the opening of the bag-shaped container is sealed, the stopper prevents the container from being damaged and securely seals the opening. There is no longer any risk of fingers being hurt by bending or ironing while using the stopper. Furthermore, there is no danger of the bag-shaped container being damaged while the bag-shaped container product equipped with the stopper according to the present invention is being transported or handled at a store or the like, and the safety is enhanced.
