DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag with a closure flap, and more particularly, to a bag with a closure flap having a structure reusable as a handbag.

[0002]

2. Description of the Related Art Conventionally, bags used for courier services are:
For example, a square-bottomed bag with or without a sticking hand made of a tough material such as kraft paper reinforced by laminating a woven or nonwoven fabric of synthetic resin stretched tape has been used in many cases. In addition, the open ends of these bags have been sealed with an adhesive tape in order to prevent the contents from falling off or being lost.

[0003]

Since bags used for home delivery are made of the above-mentioned tough materials, consumers have a strong desire to reuse them after delivery.
However, since the open end of the bag is sealed with a closing flap or adhesive tape attached to the bag, and a non-removable adhesive is used to prevent theft, etc. Although it is possible to take out an object, it is extremely difficult to remove these tapes from the opening end very clearly, and there is a disadvantage that the appearance is poor when reused. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bag with a closure flap that can be reused without substantially impairing its appearance after use.

[0004]

In order to solve the above-mentioned problems, a bag with a closure flap according to the present invention is provided with a closure flap coated with an adhesive with one wall of an open end protruding from the other wall. In the bag body formed, in order to close the bag body, a U-shape is formed on each of the inner surfaces of the bag body front and rear walls below a position corresponding to the tip of the flap when the flap is bent on the other wall. The folded hand is inverted upward from a position corresponding to the tip of the folded flap on the bag body.
It is characterized in that it is adhered so as to protrude in a character shape, and a portion protruding upward is turned downward.

[0005] The bag with a closure flap of the present invention comprises:
It is preferred to have a square bottom bag with folds on both sides, but it could also be a gusset bag closed simply by folding the bottom of the fold tube or a flat bag without folds. Also,
Even if a cut line extending over the entire width of the bag is printed on the wall of the bag along at least a position corresponding to the tip of the folded flap, instead of the cut line, the cut line extends over the entire circumference of the bag. Perforations may be provided.

A bag with a closing flap according to the present invention stores the contents, bends the closing flap on another wall, attaches the folded flap to another wall, and uses the folded flap for delivery. When the bag wall is cut along the entire circumference of the bag body along the tip and the portion above the cutting line (the portion near the opening edge), that is, the portion where the closing flap is attached, is removed, the cutting line is opened. A bag body having an edge is formed. By pulling up the hand from the inside of the bag and projecting it from the new opening edge, the function of functioning as a hand bag is achieved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto. FIG. 1 is a perspective view of a bag with a closing flap (hereinafter referred to as a bag) according to an embodiment of the present invention.
FIG. 3 is a perspective view when the open end of the bag body of FIG. 1 is sealed.
FIG. 3 is a perspective view showing a state in which the sealed bag shown in FIG. 2 is opened and then reused as a handbag.

In the drawing, reference numeral 1 denotes a bag, 1a denotes a front wall of the bag,
1b is a rear wall, 1c is a fold, 1d is an open end, 2 is a closing flap (hereinafter, referred to as a flap), 2a is its tip, 2b is release paper, 3 is a carrying hand, 3a is a flat cord made of paper, 3b
Is a backing paper, and 4 is a cutting line (printing).

The bag 1 of this embodiment is a square bottom bag having folds 1c at both ends, and a rear wall 1 at an open end 1d.
b protrudes from the front wall 1a to form a flap 2, and an inner surface of the flap is coated with an adhesive (not shown), and the coated surface is covered with a release paper 2b. (Figure 1
reference)

Referring to FIG. 2, in order to seal the bag 1, the flap 2 is bent along the front wall 1 and adhered along a position corresponding to the front end 2 a of the flap. ,
A perforated line 4 is printed on the front wall 1a, and a pair of U-shaped paper flat string carrying hands (hereinafter referred to as carrying hands) 3 are formed below the front wall 1a and the back wall 1 by a backing paper 3b.
b. The position of the hand 3 in the vertical direction is such that a paper flat string (hereinafter referred to as a string) 3a bent in a U-shape is formed in an inverted U
It is in a position protruding upward in the shape of a letter, and this protruding portion is folded downward.

In the bag 1 of the present embodiment, after storing the contents,
The flap 2 is folded over the front wall 1a, the release paper 2b is removed, and the flap 2 is adhered and sealed on the front wall 1a with an exposed adhesive.
When the bag 1 is opened, the front and rear walls 1a, 1b and the left and right folds 1c of the bag 1 are cut together along the cut line 4 printed, and the portion above the cutting line 4, that is, the flap 2
Is removed from the front wall 1a. When the portion of the string 3a bent below the hand 3 is pulled upward, a hand bag having the cutting line 4 as a new opening edge is obtained as shown in FIG. Instead of printing the cutting line 4, perforations may be provided over the entire circumference of the bag body 1 at the site to facilitate the cutting operation.

[0012]

According to the present invention, the bag with the closing flap of the present invention is used for storing the contents, folding the closing flap on another wall, attaching the folded flap to another wall, and using the folded bag for delivery. The bag wall is cut along the entire circumference of the bag body along the tip of the flap, and a portion above the cutting line (a portion near the opening edge), that is, a portion where the closing flap is attached, is removed. Is formed as an opening edge. If the hand is pulled up from the inside of the bag and protrudes from the new opening edge, it functions as a handbag. As described above in detail, according to the present invention, it is possible to provide a reusable bag with a closing flap that does not substantially lose its appearance after use.
