Description

[Detailed description of the invention] This invention relates to a carrier bag made from a relatively soft and stiff sheet such as paper or vinyl, and a reinforcing material is placed to strengthen the bag and make it independent. It is characterized by:

So-called sheet carrier bags are widely used because they have various advantages such as being cheap, convenient, and foldable. However, in many cases, the sheet of material is soft and weak, so it lacks independence, and if you place it under your feet and take your hand off it, it will collapse and fall over, or if you try to keep the bag open, it will close quickly. It also has some disadvantages, such as being left behind. In addition, sheet bags tend to break at the handle, so it is necessary to reinforce this part.

The present invention has been devised in view of the above, and will be described below based on the illustrated embodiments.

Figure 1 A shows the external shape of the carrier bag according to the present invention.
As shown in Figure B, there is a reinforcing material 3 on the inside.

The square bag 1 is made of paper or a synthetic resin sheet and is normally folded as shown in FIG. 1A, but when in use it is unfolded as shown in FIG. 1C. At that time, let the vertical length of the square bag be r, the horizontal length be l, and the width be w. The square bag 1 also has a folded part 4 around the opening.

The planar shape of the reinforcing member 3 is as shown in FIGS. 2 to 5, and as is clear from these figures, its outer edge shape is basically a trapezoid. Various embodiments of the reinforcing material 3 can be considered based on this basic form. The one in Figure 2 is the simplest in shape, and is made by cutting a piece of cardboard into a trapezoid with height r and base l+2W. This reinforcing material 3 is folded horizontally as shown by a chain line with both ends w-long portions of the bottom as demarcating pieces 5, and the lower side 6 is set as l, and two pieces are put into the square bag 1. Then, the upper side 7 portion of the reinforcing plate 3 is inserted into the folded part 4 of the square bag 1, and the hand 2 is attached to the first
It is installed by penetrating it as shown in Figure B. The one in FIG. 3A is an inverted V-shape inscribed in a trapezoid with a height r and a base l+2w as shown in the figure, and defining pieces 5 are set at both ends of the base. The delimiting piece 5 is bent horizontally. This type of reinforcing material 3 can be formed by continuous punching from a long plate material (cardboard, etc.) with a width of l + 2w, as shown by the chain line in the figure, and many reinforcing materials can be taken from the same material. . The one in FIG. 4B is similar to the one in FIG. This type is also convenient to make by punching from a long board with a width of 1, and there is less waste of the board. Fifth
The one in the picture is made by bending a strip of board material. A is a type with diagonal cuts at both ends, B is a type with right angle cuts. In either case, defining pieces 5 are set at both ends. In case A, it can be formed by simply folding both ends horizontally, but in case B, as shown by the chain line, the ends are folded upward and then horizontally bent inward. In the case of the type shown in Figure 5, it is possible to use thin strip-shaped boards (cardboard, etc.) continuously and is inexpensive, and as will be described later, the attachment point of the handle is folded double over the strip-shaped board. Since it is a small piece, the place where the handle is attached is strong.

Now, the reinforcing material 3 formed in this way is made into a pair, and for example, as shown in FIG. Insert and place it, then hand 2
is attached and fixed by passing through the reinforcing material 3 from above the folded portion.

Initially, the delimiting piece 5 is placed in a folded state, but when in use, it is expanded in the right angle direction as shown in FIG. 7 to define the width w of the square bag 1.

Therefore, according to the present invention, when the folded dividing piece 5 is opened in use, its length is the same as the width w of the square bag, and both sides of the square bag 1 are located at the bottom. Since the square bag 1 is protruded from the opposite sides, the shape of the bottom surface of the square bag 1 is maintained stably, and the square bag 1 is able to stand on its own and maintain its shape due to the rigidity of other parts.
Furthermore, the opening will not collapse. If the reinforcing material 3 is fixed to the side wall of the square bag 1 by gluing or the like, the bag body is reinforced by expanding the side wall in the lateral direction and dispersing the hanging force to the square bag.

Furthermore, since the reinforcing material is basically trapezoidal in shape, the upper side inserted into the folded part of the square bag reinforces the part of the upper part of the square bag where the handle is attached, and
By widely supporting the wide sides of the square bag all the way to the bottom, it is possible to suppress the bag from protruding in the lateral direction due to the contents. In this case, if the reinforcing material is glued to the square bag as in the above example, the lifting force from the handle will be diffused in the direction of the bottom length l of the bag along the legs of the trapezoid, and the material will be stored in the bag. Since the weight of the article is not concentrated on the handle attachment part of the square bag, it is possible to prevent the bag from being torn from the handle part. In addition, since the hanging force can be transmitted to the entire bottom of the square bag,
By hanging a part of the bag, it is possible to prevent the bag from breaking and the bottom from hanging down. Furthermore, if it is trapezoidal, a defining piece can be easily created by simply folding back both ends of the lower side.

Note that a bottom plate (such as cardboard) may be placed at the bottom of the square bag 1.
