Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bag made of a synthetic resin film or a composite film of a synthetic resin film and, for example, aluminum foil.

<Prior Art> A bag made of a synthetic resin film or a composite film of a synthetic resin film and aluminum foil, and provided with a synthetic resin fastener on the inside of the opening, is conventionally known.

<Problems to be Solved by the Invention> Conventionally known bags with zippers allow the contents to be easily taken out by opening the zipper and fully opening the opening of the bag. Another advantage is that by closing the fastener, the contents can be stored without spilling. By the way, when the contents are liquid, granules, powder, etc. and are taken out in small quantities as necessary, it is desirable to make the opening of the bag small. However, in the case of fasteners, when the occlusion is partially opened, the entire occlusion is removed and the opening of the bag is fully opened. Therefore, it is not easy to take out the contents such as the liquid, granules, powder, etc. in small amounts as necessary from the fully opened opening, which results in taking out too much.

An object of the present invention is to provide a bag that allows the contents to be easily and quantitatively taken out in small quantities as needed, and that takes advantage of the resealable functional characteristics of the zipper.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a bag body equipped with a synthetic resin fastener on the inside of the opening, with a width of the bag body and a side surface of the opening above the fastener. A piece of film folded in half of the same width is glued on both sides of the bag, one end of the film piece in the width direction is glued to one of the inner surfaces of the bag, and the other end is attached to the bag. It can be attached to the other inner surface of the body.

<Function> In the bag according to the present invention, the other end in the width direction of the film piece is glued to the inner surface of the bag until the contents are filled with an automatic filling device or the like at a content production factory or the like. Fill it with the contents and glue it at the same time. As a result, the opening of the bag above the fastener is sealed by the folded film piece and the closure of the fastener. When taking out the contents, a small opening is made in one corner of the folded film piece by diagonally cutting the corner of the bag above the fastener using scissors or the like. Therefore, even when the fastener is opened and the opening is fully open, the contents can be taken out from the small opening made in the film piece, making it easy to take out a fixed amount in small quantities. By re-closing the opening, the opening becomes sealed and the remaining contents can be preserved.

<Examples> Examples of the present invention will be described below based on the drawings. In FIG. 1, 1 is a bag body made of synthetic resin film, etc., and two films 1a and 1b face each other with side seals 2 and a bottom seal 3.
etc. have been applied. Further, inside the opening of the bag body 1, a fastener (closing tool) 4 that can be reopened and closed is provided in the bag width L direction.

Bags with fasteners as described above are conventionally well known. The present invention provides such a bag 1 with an opening 5 above the fastener 4 as shown in FIG.
A film piece 6 folded in half with a width equivalent to the bag width L of the bag body 1 is attached to the side, and both ends thereof are glued together with both side seals 2 of the bag body 1, and one end of the film piece 6 in the bag width L direction is glued to the side. The part 6a is one film 1a of the bag body 1.
The other end 6a can be adhered to the inner surface of the other film 1b of the bag 1.

Since the present invention has the structure as described above, the bag body 1
When filling the inside with an automatic filling device or the like, when the fastener 4 is opened, the opening 5 side opens wide as shown in FIG. 3, and the contents can be easily filled. After filling the contents, as shown in Figure 4, the other end 6b of the unattached film piece 6 is glued 7b to the inner surface of the other film 1b of the bag 1, and the fastener 4 is closed. do.
As a result, the opening of the bag 1 has a fastener 4
Although the bag and the film piece 6 form a completely sealed state, in order to further ensure safety, it is preferable that the edge on the opening 5 side is glued 8 in the direction of the bag width L. In this case, it is desirable to provide a cut line 9 below the adhesive 8 in the bag width L direction to facilitate opening. Further, if the cut line 10 is formed slightly above the fastener 4, there will be a practical benefit as will be described later.

When dispensing a fixed amount of the contents in the sealed bag 1 and when the cut line 9 is applied, first tear the bag from the cut line 9 to remove the adhesive 8, and then remove the adhesive 8 as shown in FIG. The corner on the opening 5 side is cut 11 diagonally using scissors or the like. When the fastener 4 is opened, the opening 5 widens until the film piece 6 folded in half is fully expanded, as shown in FIG. is realized. That is, this small opening 1
2 serves as a spout, and the contents can be easily and reliably dispensed in small quantities.

Further, when taking out the contents at once, by tearing from the cut line 10 above the fastener 4, the film piece 6 is also cut and a large opening is obtained, so that the entire contents can be taken out quickly. After the entire contents are taken out, other contents are put in and the fastener 4 is closed, thereby functioning as a conventional bag with a fastener, and the bag 1 can be effectively utilized.

<Effects of the Invention> As described above, the present invention provides a fastener (occlusal device).
A piece of film folded in half with the same width as the bag is attached to the upper opening side, and its both ends are glued together with both sides of the bag, and one end of the film piece in the width direction is attached to the inner surface of the bag. Since the film is glued to one side and the other end is not glued to the other inner surface of the bag until the contents are filled, the film can be opened wide without the film becoming an obstacle when filling the contents. After filling the contents, the other end of the film piece is glued to the other inner surface of the bag, so that the opening of the bag is double-layered by the fastener and the film piece. A sealed state is obtained, and furthermore,
When the upper edge of the opening of the bag is glued, it becomes a triple seal, and even if the fastener opens when heavy pressure is applied to the bag, there will be a double back-up effect at the adhesive part of the film piece and the upper edge of the opening. and
Reliably prevent contents from spilling out.

In addition, when taking out a fixed amount of contents in small quantities, by cutting the opening corner above the fastener diagonally, a small opening is obtained at one end of the film piece, and a small amount can be taken out reliably.
By closing the fastener, the remaining contents can be stored in a hermetically sealed state.

Furthermore, by cutting above the zipper in the width direction of the bag, a large opening can be obtained, allowing quick removal when removing all the contents at once, and the bag can be re-closed using the zipper after the entire contents have been removed. It has many functions and effects that cannot be obtained with conventional bags with zippers, such as being able to be used as a bag.
