DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a packaging bag formed by integrally forming a handbag portion (top handle). More specifically, the opening portion thereof is sealed. In an envelope type packaging bag having a lid for forming a lid body, the lid body is formed to be considerably long, a pair of U-shaped cuts are provided at predetermined positions of the lid body, and an adhesive is applied to the upper end portion of the lid body. It is an adhesive edge, and when the adhesive edge is adhered to the back opening edge of the bag body, the lid body folds in the middle, and in this state the U-shaped notches overlap each other, put your fingers in this It is a bag that can be provided, and it is convenient that the handbag part is formed immediately when the bag is covered, and it is a bag that can be offered at low cost because there is no manual processing in the bag manufacturing process and full-automatic production is possible. .

(Prior Art) Speaking of conventional packaging bags with a handbag, most of them have a pair of inverted U-shaped strings attached to the opening edge of the bag body made of paper or a synthetic resin sheet or the like. It is often used in supermarkets, etc. With the gussets (towns) provided on both sides of the bag body, the opening of the bag is cut into a U-shape inside the gussets on both sides, that is, a running shirt shape. There is one.

(Problems to be solved by the invention) Conventionally, the above-mentioned two types of bags with handbags are service goods to customers, so expensive ones are not suitable. Appearances are unsuitable for some applications. For example, with regard to the two typical types of packaging bags described above, the former is good in appearance, so there is no problem even if you walk around the city with gifts, but the latter running shirt type has a point of appearance. It is inferior and is not suitable for ritual purposes. The packaging bag is required to have a certain image depending on the condition of the items put in it. On the other hand, for courier service and the like, there is a demand for a packaging bag that has protection against rain and is easy to carry. Under such circumstances, there is a demand for an inexpensive, convenient, and durable one that can be used for many years.

(Means for Solving Problems) The present invention has been completed as a result of various studies for solving the above problems, and its basic technique will be described with reference to FIG. Bag body using a film
It consists of (a) and a lid (3) in which the front wall (1) of the bag is formed to be considerably long.The lid is not a short one like an envelope lid, but rather has a considerably long dimension, and the degree depends on the application. Although slightly different, when the adhesive part (4) at the upper end of the lid (3) is adhered to the rear opening of the main body (a) and the state shown in Fig. 3 (a) is reached, the height of the lid body folded in two is increased. Has a few centimeters and has three sides of a rectangle (U-shaped)
When the cut line (5) is formed, the hanging piece (b) generated by this cut is pressed with a finger to form a window (6), and the upper beam portion (7) of the window is to be grasped with fingers. Put it.

Based on the above-mentioned basic technical idea, various more practical deformations are conceivable. Therefore, as described below, when a synthetic resin film molded into a tube is folded flat, as shown in FIG. , Cut gussets (10), (10) on both side edges to a certain length, and at the same time, cut ends are heat-sealed (11) to form the bottom of the bag, and the upper part is the back side of the bag. wall
By cutting (2) with the cutting line (12), the bag body (a)
To form the lid (3), but in this case, in order to further enhance the practicality, the part connected to the front wall (1) of the gussets (10), (10)
Cut only (9) and fuse the upper end to the lid (3)
(9 '). By doing so, the edges on both sides of the opening are not torn, and the bag is not torn vertically when the item is put in the bag.

Next, as shown in FIG. 3, a carrying part is formed, and when the product is put in a bag when carried by hand, it is preferable to reinforce the beam part (7). In such cases, the fourth
As shown in the figure, the back side of the lid (3) has a wall (2) behind the bag from the opening cut line (12) of the bag to the folding line (8) of the bag.
However, the bag wall above the fold line (8) is left and the reinforcing piece (2 ′) is formed, whereby the lid portion above the fold line (8) and the same size as the lid portion. It is constructed so as to be formed in a double stack with this reinforcing piece (2 '). The upper edge of the reinforcing piece is heat-sealed (13) to the lid (3).
The reinforcing piece is not limited to the above-mentioned structure because it can achieve the purpose of reinforcement, and for example, in the case of reinforcing the upper beam portion (7) of the window (6) in FIG. 3 (a). As shown in FIG. 5, the back wall (2) of the bag is left up and down around the folding line (8) of the lid (3), or alternatively, a thick vinyl sheet or cardboard is used. Processing such as sticking the same to the portion is performed.

Each of these forms, the shape of the item to be put in the bag,
It can be freely selected according to the weight. Appropriate means can be adopted for the configuration of the adhesive section (4). For example, peel off the release paper on one side of the double-sided adhesive tape and put it on the adhesive part (4), and when closing the opening of the bag, remove the other release paper and stick the part on the back of the bag. The way to do is convenient.

(Operation) Since the present invention relates to the above configuration, the lid body (3)
It is a convenient thing to put the adhesive part (4) on the back side of the bag immediately and the handbag part will be constructed.
When the lid is folded in two from the folding line (8) of (3) and the lid adhesive part (4) is attached to the back of the bag to seal the opening of the bag, the score line formed on the lid (3) itself ( When 5) and (5 ') overlap each other and push the hanging piece (b) with your finger, the window (6) opens and you can hold the upper beam part (7) of the window with your fingers to carry the bag. The part is formed.

There are various ways to reinforce the handbag part.As mentioned above, a part of the tube that is the material is left as the reinforcement part (2 '), which is the opening of the bag by folding the lid (3) in two. When the bag is sealed, the material of the handbag is tripled, increasing its strength. There is also a method in which an appropriate reinforcing material is applied to the upper and lower parts of the folding line (8) of the lid (3), thereby increasing the strength of the handbag portion and adapting it to a wide range of appearances. Any means may be used for applying the reinforcing material, but heat fusion is efficient and suitable for the purpose of the present invention.
