Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a packaging bag such as a so-called hand-held paper bag.

[0002]

[Prior art]

 Such a packaging bag is formed in a rectangular shape when viewed from the front. The lower end of the tubular body having a rectangular cross-sectional shape is closed like a caramel wrap to form a rectangular bottom, and a hand is attached near the opening at the upper end. Then, the left and right side edges are folded inward so that they can be folded into a compact flat shape, and the bottom is folded back to the front or back side.

[0003] By the way, when the packaging bag is held in a hand, it is in a state of being along the lower body part of the human body. However, in the above-described packaging bag having a rectangular shape in a front view, the human body along which the bag extends is thinner toward the lower side. Nevertheless, they have the same width. For this reason, it has a terrible impression, does not look very stylish at first glance, and looks thick to humans.

[0004] In particular, when the bag is used for a wedding present or when a large number of articles are stored, an excessively dull impression is obtained when the bag is thick. Conversely, even if there are too few items to store, they will be thin and look bad.

[0005] Furthermore, when an article is put in and handed, the opening of the bag tends to open naturally because both side edges are folded inward. Because of this, the appearance is not good, and there is a case in which an uneven engaging portion is also provided at the base of the hand.

Further, since the packaging bag is rectangular in a front view, the size of the bottom of the packaging bag and the size of the opening are the same. That is, even if the opening is fully opened, the opening feels small compared to the size of the bottom because of the depth. In other words, the workability is often poor, such as the interior is difficult to see when putting goods in and out, and the bag is unexpectedly torn.

[0007]

[Problems to be solved by the invention]

 Therefore, the main issue of the present invention is to provide a packaging bag that gives a stylish impression when it is held, whether it contains many or few items and that is easy to use.

[0008]

[Means for Solving the Problems]

 The means for this is to form an opening at the upper end that can be closed flat without weaving the left and right side edges inside, and to taper both sides below the opening so that the width becomes smaller toward the lower side. It is a packaging bag formed in a slanted shape.

[0009] That is, when this packaging bag is held in a hand, the both edges are inclined so that the lower edges are narrowed in the same manner as the legs of a human body are tapered downward, so that the packaging bag is slim. It gives an impression and looks fashionable. In addition, even the person holding it looks thin. The same applies when the packaging bag is put on the shoulder or when it is held in front of or beside the body. In addition, the side edges are located on the outside, and the opening at the upper end is the widest. Therefore, when the bag hits something, the side edges first hit and act as a buffer to protect the stored goods.

[0010] If a lower end is provided with a boat-shaped bottom having a flat inner bottom surface, the inclined side edges are not directly in contact with the horizontal bottom surface, but through the inclined portions located before and after the boat shape. Therefore, a more beautiful appearance can be obtained. In addition, the inclined portion serves as a cushion together with the both side edges to protect articles stored therein from impact. In addition, because of the flat inner bottom surface, when articles are stored, they can be stably stored, and the opening does not need to be unduly widened. In this respect, the appearance can be improved.

[0011] If such a boat-shaped bottom is formed to be flat and foldable, it can be compactly deformed when not needed.

In addition, when a core material for giving a stiffness to the opening is held in the entire length of the opening, the opening serves as a reinforcement when a hand is attached, and the wide opening is emphasized to enhance the beautifulness. Get the impression. In addition, even when articles are stored, the opening can be urged in a direction to close the opening, and from this point the appearance of the storage bag itself and the person holding it can be improved.

[0013] In addition to the attachment of the carrying hand, a carrying hole may be formed at the upper end having the opening.

[0014]

[Embodiment of the invention]

 One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state in which articles are stored in a packaging bag 1 (hereinafter, referred to as a bag). As shown in this figure, the bag 1 has an opening 2 for taking in and out articles at an upper end, and a lower end. The left and right side edges 4, 4 connecting the opening 2 and the bottom 3 are formed in a tapered shape that becomes narrower toward the lower side, in other words, in the opposite direction. It is formed like a triangle.

The opening 2 is closed flat without folding both side edges inward. The bottom 3 of the boat-shaped vessel has a flat inner bottom surface 3a (see FIGS. 2 and 8), and has an inclined portion 3b, 3b that is warped before and after (left and right).

FIG. 2 is a front view of the packaging bag 1 in a state where the packaging bag 1 is folded flat. The inclination angles of the side edges 4 and 4 are appropriate angles that are neither too tight nor too gentle, for example, as shown in FIG. Setting the same angle as the inclination of the thighs of the trousers gives a more natural and good appearance.

The bottom 3 has a three-dimensional shape having the flat inner bottom surface 3a as described above, and is foldable.

The bag 1 can be formed of a suitable material such as paper, synthetic paper, synthetic resin sheet, cloth, and the like. When the cut material (base material) is formed by bonding (sealing), the material may be cut into a shape as shown in FIGS.

The base member 5 shown in FIG. 3 is formed by arranging two front and back sheet portions 5a, 5a in a shape corresponding to the shape of the bag 1 in a plan view on the left and right sides, and folding the upper and lower sheet portions 5a, 5a at the upper edges thereof. 5b is formed at the lower end with a bottom forming portion 5c. An adhesive margin 5d is formed on one side edge of one of the front and back sheet portions 5a and on the lower side thereof.

The folded-back piece 5d has an end portion cut obliquely so as to fit inside the bag 1 when folded. The bottom forming portion 5c is formed in a shape that complements the lower portion of the hexagonal front and back sheet portion 5a to form a square.

In the figure, a broken line and a dashed line represent a folding line. If the broken line is a mountain fold, the dashed line is a valley fold. If the broken line is a valley fold, the dashed line is a mountain fold.

In the base member 6 shown in FIG. 4, the lower portions of the front and back sheet portions 6a, 6a are formed so as to face each other via a bottom sheet portion 6b forming the inner bottom surface 3a. A folded piece 6c is formed on the upper edge of the two front and back sheet portions 6a, 6a, and an adhesive margin 6d is formed on both left and right edges of the front and back sheet portion 6a and the folded piece 6c located on one side. At both left and right sides of the bottom sheet portion 6b, an inclined portion forming portion 6e which forms the inclined portion 3b of the boat-shaped bottom portion 3 is formed.

Similarly, a broken line and a dashed line represent a folding line. If the broken line is a mountain fold, the dashed line is a valley fold. If the broken line is a valley fold, the dashed line is a mountain fold.

In each of the base materials, insertion holes 5e and 6f for attaching a hand are formed at positions corresponding to the upper end portions of the front and back sheet portions 5a and 6a and the folded pieces 5b and 6c.

The base materials 5 and 6 having such a shape are folded along the folding line, and are bonded to the opposing portions at the bonding margins 5d and 6d to form a bag. At this time, as shown by the broken line in FIG. 5, when the folded pieces 5b and 6c are folded, the core material 7 having the length of the entire length of the opening 2 is sandwiched. The core member 7 is for giving a stiffness to the opening, and may be formed of cardboard or a thin synthetic resin plate having flexibility.

The hand 8 may be formed of a suitable member such as a string, and when formed with a string, as is well known, a knot 8a may be formed at an end portion of the hand to prevent the hand from coming off.

FIG. 5 is a diagram in which the bag 1 formed of the base material 5 of FIG. 3 is folded flat. When the bag 1 formed of the base material 6 of FIG. Since it is folded into a mold, it becomes as shown in FIG.

In the bag 1 configured as described above, when articles are stored, the bottom portion 3 expands and becomes a boat-shaped state as shown in FIG. In other words, a soft impression with sharp corners is produced, and a novel design feeling is obtained.

The left and right side edges 4 and 4 are inclined so as to form an inverted triangle as apparent from the vertical line shown by the imaginary line, and the widest is the upper opening 2. Therefore, when the user holds and holds the hand 8, the shape of the bag 1 located on the lower side of the body becomes similar to the shape of the slant of the human body which becomes thinner downward. For this reason, it is possible to dispel the stubborn image of the conventional bag and to make even the human body holding it look slimmer.

In addition, if the bag 1 is made of paper or synthetic paper having appropriate hardness, the bag 1 has a shape-retaining ability. Yes, you can carry around. In addition, even if many articles or large articles are put in, the large opening allows easy storage, and the bag can be packed neatly without breaking the shape of the bag.

Further, since the opening 2 holds the core material 7 having a length extending over its entire length, the wide opening 2 has a waist and a tight state. For this reason, the remarkable effect of the above-described special configuration can be enhanced, and the opening 2 can be urged in the closing direction, which also improves the appearance of the article when stored. can do.

When the bag 1 is opened and viewed from above, as shown in FIG. 8, the opening 2 is wider than the inner bottom surface 3a, so that the inside can be seen well. For this reason, articles can be easily taken in and out, and unexpected breakage can be prevented. Also, as described above, large items and many items can be stored neatly, so they are ideal for use as a bag for a wedding present or as a lucky bag for the New Year.

Further, since the bottom portion 3 is boat-shaped, when an article is put on the inner bottom surface 3a and stored, even if it has and accidentally collides with something, both the boat 3 and the boat-shaped sloped portion 3b of the bag 1 are used. The impact can be reduced by the side edges 4 to protect the articles inside.

The material and form of the bag 1 may be appropriately set according to the purpose. FIG. 9 shows a bag having a vertically long shape. Further, the hand 9 is formed by one string. That is, four insertion holes 11 are formed at both end positions near the opening 2 by attaching eyelets 10 or the like, and one string is sequentially passed through all the insertion holes 11 to form a set of one. Both ends of the string are connected between the insertion holes 11 and 11. In addition, as shown in FIG. 11, two eyelets 10 may be stacked and stopped so as to close the opening 2, and two insertion holes 11 may be formed. Since the opening 2 is wide, there is no inconvenience in taking in and out of the article, and it is possible to hold the article not only by hand but also by hanging it on the shoulder. Even when held over the shoulders, the unique shape of the bag matches the shape of the body, giving a good appearance.

FIG. 12 shows an example of a bag in which an oval-shaped hand hole 12 is formed in place of a hand in order to insert a hand. The other parts are the same as those described above, and thus are denoted by the same reference numerals, and detailed description will be omitted.

The above is one embodiment of the present invention, and the present invention is not limited to the above-described configuration.

[0037]

[Effect of the invention]

 As described above, according to the present invention, since both sides on the lower side from the opening have a novel shape that is inclined so that the width becomes narrower toward the lower side, a large and stylish feeling can be obtained, and the shape along the body can be obtained. When held together, the lower part becomes narrower in the same way as the body shape, so the body looks slim and the appearance improves.

Further, by forming the boat-shaped bottom, a good rounded appearance can be obtained, and the opening can be prevented from opening even when articles are stored.

In addition, if the core material is held over the entire length of the opening, the opening becomes stiff, so that the presence of the wide opening makes it possible to improve the appearance and improve the quality of the articles to be stored. Even if the amount is large, it can be urged in the direction to close the opening, and even if the amount of articles to be stored is small, the area near the opening does not drip or open, and the wide opening is stretched. It can be packaged in a certain shape.

Further, since the opening at the upper end is the widest shape in the packaging bag, the inside is clearly visible when the opening is opened, and the bag is not accidentally broken, Goods can be taken in and out easily and it is easy to use.
