Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to a packaging bag with an outlet, and particularly to a packaging bag with an outlet that stores sheets of paper, cloth, etc. impregnated with a chemical such as alcohol. It's about bags.

<Prior Art> In recent years, disposable wet napkin products in which sheets of paper, cloth, etc. are impregnated with chemicals such as alcohol have come into widespread use.

There are many types of storage containers, such as bags and boxes, but most of these are bulky because they are made of synthetic resin injection molded products or vacuum molded products.

Among these, a bag with an opening/closing lid is a container that is particularly inexpensive and easy to manage in terms of production technology.

As shown in FIG. 1, such a bag body has an opening 2 formed by cuts on three sides in a part of the bag body 1, and a lid 6 is attached to cover the opening 2. The bag was warm, but when the opening 2 of the bag was opened, the opening did not stop at the end of the cut in the bag body 1, and there was a risk that the bag body 1 other than the opening would be torn.

Furthermore, when the bag body 1 is made of a material that does not have shape retention properties, it has the disadvantage that it becomes distorted and wrinkled when opened and resealed, and the bag body 1 is not aligned properly when resealed.

<Problems to be solved by the invention> The present invention was made to solve the above-mentioned problems, and it is possible to prevent the package from being opened more than necessary, and also to prevent the package from shifting its position when resealing. The present invention provides a packaging bag with a take-out port.

<Means for Solving the Problems> In order to solve the above problems, the present invention has a bag body made of a laminated film with an opening formed by a perforation line, and a hole that is the same as or slightly smaller than the opening is formed on the back side of the opening. A fixing plate having the following properties is fixed to the entire periphery of the opening, and a lid body having a pressure-sensitive adhesive layer provided on the surface of the bag body is adhered to cover the opening part, and the lid body is formed to a size that overlaps with the fixed plate.

Further, it is preferable that the opening has a keyhole shape.

<Function> According to the present invention, since the fixing plate is fixed to the entire back surface of the bag body, when one end of the lid body is pinched and pulled off, one end of the opening is attached along the cut line of the bag body. The lid is further torn, and the torn part is stuck to the lid side and unsealing progresses, and the unsealing stops at the other end of the opening.

In addition, according to the present invention, since the fixing plate is fixed to the entire back surface of the bag body, it is possible to keep the opening periphery of the bag body in a flat state without distorting or wrinkling when opening and resealing. As well as being able to
When the package is opened, the broken portion cut along the tear line remains attached to the lid, and can be resealed by aligning it with the hole formed when the package is opened.

<Example> The present invention will be explained below with reference to the drawings.

As shown in FIGS. 2 and 3, the present invention has a bag body 1 made of a laminated film with an opening 2 formed by a perforation line on one side, and a hole 3 that is the same as or slightly smaller than the opening 2. A fixing plate 4 made of a plastic sheet is completely fixed to the periphery of the opening 2, and a lid 6 is provided with a pressure-sensitive adhesive layer 5 on the surface of the opening 2 so as to cover the opening 2. This is a packaging bag with an outlet, in which the lid body 6 is formed in a size that overlaps the fixing plate 4.

The opening 2 of the present invention is not simply circular, but is preferably shaped like a keyhole, with a wide opening start part and a narrow end part, making it easier to take out the bag and reducing the risk of tearing the bag when opening.

The fixing plate 4 provided on the back surface of the opening 2 is preferably made of the same resin as the back surface of the bag body, and is preferably heat-sealed around or on the entire surface, but may be fixed using a pressure-sensitive adhesive.

<Effects of the invention> Since the present invention has the above-described structure, it is possible to prevent the bag from being opened more than necessary, and the position of the bag does not shift when it is resealed, making it easy to open and reseal the bag. This is a packaging bag with an outlet.
