Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a packaging bag made of a sheet material such as paper.

[0002]

[Prior art]

 Until now, shopping bags, such as shopping bags made of sheet material such as paper, often have a horizontally long opening facing the center of the front and back of the bag near the upper edge of the back for carrying. It is used.

[0003]

[Problems to be solved by the invention]

 However, when such a bag is small, the carrying opening extends to the vicinity of both sides. Therefore, if the user tries to grip the bag in a state where the bag is folded along the center line extending vertically at the center in the width direction of both sides, the center portion of the folded side portion is exposed to the hand-held opening and the hand is exposed. It will not be accessible or difficult to access.

An object of the present invention is to provide a packaging bag made of a sheet material which is easy to hold even a small bag without such a problem.

[0005]

[Means for Solving the Problems]

 To achieve this object, the packaging bag of the present invention is made of sheet material, and has side edges extending up and down, and has opposed front and rear portions, one side edge on the front side edge, and The other side edge has first and second side surfaces connected to the side edge of the back surface portion, and the front surface portion, the back surface portion and the first and second side surface portions form a bag-like portion and open to one side. A packaging bag having a bottom portion on the side opposite to the one side and foldable along a center line extending vertically in the width direction center of the side surface portion, near the center of the upper edge of the front portion and the back surface portion. The first and second side surfaces are formed with the opening for facing the hand, and the first and second side surfaces are folded when the side surface is folded along the center line. And a portion facing away from is formed to form an auxiliary opening.

[0006]

[Embodiment of the invention]

 Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a bag made of a sheet material according to the embodiment. When completely opened, the bag 1 has a box-like shape that is open upward, and has a large front and rear surface 2 and a rear surface 3, which are long vertically, and are small connecting the front and rear surfaces 2 and 3. It has a first side surface 4 and a second side surface 5 having an area, and a bottom 6.

In the upper central part of the front part 2 and the back part 3, openings 11 and 12 for carrying are provided, respectively. In the present embodiment, the carrying openings 11 and 12 have a substantially heart shape in which the upper edges extend horizontally and the lower central portion is wide. Such a shape is easy to reach, easy to hold, and has a stylish design.

[0009] The curving portions extending downward from both ends of the upper edge of the handheld openings 11, 12 are cut, and the cut portions are folded along the upper edge of the opening into the upper edge inside the bag to form the upper edges. To form a reinforcing portion. Only one of them is shown as 12a.

[0010] The packaging bag according to the present embodiment can be preferably formed by folding a single sheet material.

The packaging bag according to the present embodiment has both side portions inward along a center line extending vertically in the width direction center of the first and second side portions 4 and 5 along a dashed line in FIG. It can be folded into a so-called squatter, and at the bottom of the bag, from both sides toward the center, as shown in FIG.

Auxiliary openings 15 and 16 are provided opposite to each other in the vicinity of the upper edge in the widthwise center of the first and second side surfaces 4 and 5. As shown in FIG. 2, these auxiliary openings 15 and 16 are opposed to the front and rear opening portions 11 and 12 when the bag is folded along the center line extending vertically in the widthwise center of both sides. The openings 11 and 12 have a shape and a size such that both side surfaces do not interfere when the hands are put into the openings 11 and 12, and for example, similar to the openings 11 and 12 as shown in the drawing. It is good to make the bag look better.

The auxiliary openings 15 and 16 are also cut at a curved portion extending downward from both ends of the upper edge of the opening, and the cut portion is folded inside the bag along the upper edge of the opening and folded into the upper edge of the bag. It is.

Next, a second embodiment of the present invention shown in FIGS. 3 and 4 will be described. The difference between the second embodiment and the first embodiment lies in the configuration of the second side surface portion. Hereinafter, different portions will be described, and description of the same portions will be omitted.

In the second embodiment, the second side surface portion 5 is formed of an inner side surface member 5a and an outer side surface member 5b. The inner side surface member 5A and the outer side surface member are formed at least on both side edges. The part is connected to the front part 2 and the back part 3 vertically.

In this manner, a large bag portion is formed by the front side portion 2, the first side surface portion 4, the back side portion 3, and the inner side surface member 5a of the second side surface portion, and the inner side surface member 5a and the outer side surface member 5b form A small bag-like portion or a tubular portion extending vertically is formed.

In the present embodiment, auxiliary openings 15 and 16 similar to those in the first embodiment are formed in the first side surface portion 4 and the inner side surface member 5a of the second side surface portion, respectively. The upper edge of the outer side surface member 5b of the second side surface portion 5 extends obliquely from both ends toward the center in the width direction to a position near the lower part of the auxiliary opening 16 of the inner side surface member. Therefore, it is easy to open and close the space between the inner side surface member 5a and the outer side surface member 5b as shown in FIG. 4, and the opening can be enlarged, so that objects can be easily contained.

Next, a third embodiment shown in FIG. 5 will be described.

The third embodiment is different from the second embodiment in the configuration of the upper edge of the outer side surface member 5 b of the second side surface 5. That is, in the third embodiment, the upper edge of the outer side surface member 5b has a simple shape in which the vicinity of the lower end of the auxiliary opening 16 of the inner side surface member 5a extends horizontally in the width direction, and thus the packaging is easy to manufacture. It is a bag for.

In the second and third embodiments, the outer side surface member 5b of the second side surface portion may be formed of one sheet together with other portions constituting the bag, but the front portion 2 and the first Any one of the inner and outer side members 5a and 5b of the side surface portion 4, the back surface portion 3 and the second side surface portion 5, and the bottom portion are machined with a single sheet material by a conventional method. A thing may be pasted up manually.

According to the second and third embodiments, the second side portion has a double structure, the bag becomes stronger, and a bag-like portion or tube extending vertically on one side of the bag. It has a shape, and it is easy to insert long objects such as flowers.

[0022]

[Effect of the invention]

 According to the present invention, a packaging bag having a simple structure and easy to hold can be obtained even in a small packaging bag.
