Description

[Detailed description of the invention] The present invention mainly consists of a cylindrical bag that can be opened up and down, and strings for sealing the bag are attached near both ends of the upper and lower opening ends, respectively. This is a bag with a string for sealing a body bag, and is designed so that the capacity of the bag can be arbitrarily adjusted according to the amount of powder, granules, etc. to be stored, and the bag can be sealed easily and reliably.

Conventionally, for example, in bags containing a large amount of cement, flour, and other powders, the sealing method was generally to sew both the top and bottom ends using a bag-making machine such as a sewing machine. Sewing machines and other bag-making machines are required, which increases costs, and if the storage capacity is small, put powder, etc. in a bag with a sewn bottom end, fold the top end over and hang a rope in a criss-cross pattern. However, the shape of the packaging was unsightly as it bulged out, and the bags were piled up in a messy manner, and in both cases, it was time-consuming to seal the bags. In addition, in recent years, it has been proposed to attach a string for bondage to the open end, but the string is inserted into or attached to a tube formed by folding the end of the bag. , its installation is time-consuming.

The present invention has been made in consideration of the above, and is characterized by a bag with a sealing string, which is formed by folding both sides of a tubular bag body which opens at the top and bottom into a gusset shape, and by attaching a string for sealing the bag by passing through the front and back at the multiple portions formed by the gusset-shaped folds on both sides at the top and bottom opening ends of the tubular bag body.

Next, embodiments of the present invention will be described based on the drawings.

1 is a cylindrical bag with vertical openings made of paper such as kraft paper, cloth such as woven fabric, single layer or multilayer material such as synthetic resin film or sheet, etc.
As shown in the figure, both sides are folded into a gusset shape. Bag-sealing strings 4, 4, 5, and 5 are attached to both upper and lower open ends 2 and 3 of the cylindrical bag body 1 at the multiple parts formed by the gusset-like folds on both sides, passing through the front and back sides. It is worn. This string 4, 4, 5, 5
For example, as shown in the figure, eyelet-shaped holes 6, 6, 7, 7 are formed through the multiple parts formed by the gusset-like folding on the front and back, and the holes 6, 6, 7, 7 are filled with predetermined holes. It can be easily attached by passing the strings 4, 4, 5, and 5 through and tying it.

The present invention is constructed as described above, and in its use, first, the lower opening end 3 of the cylindrical bag 1 is tied with the strings 5,
With the string pulled out to both sides, wind it an appropriate number of times and fold it over (Fig. 3), and then bend the both ends inward into a triangular shape and tie the strings 5, 5 together at the center. By doing so (FIG. 4), the above-mentioned rolled, folded and overlapping state is maintained to keep the lower open end 3 in a closed state to form a bottom. After storing a predetermined amount of powder, granules, etc. inside the cylindrical bag 1, the upper opening end 2 is opened with the strings 4, 4 pulled out to both sides in the same way as the lower opening end 3. By winding and folding an appropriate number of times depending on the amount (Fig. 5), and further bending both ends inward in a triangular shape and tying the strings 4, 4 together at the center (Fig. 5), (Fig.), it is only necessary to maintain the above-mentioned rolled and folded state, that is, the upper open end 2 in a closed state, and the bag sealing can be easily completed. In this bag-sealing state, a strong force is applied to the open end of the cylindrical bag body 1 to which the bag-sealing strings 4, 4, 5, and 5 are attached, but the points where the strings are attached are particularly gusseted. Since the bag is made up of multiple folded parts, and the opening end including the attachment part is wrapped around the bag, it can withstand the tensile force mentioned above even without special reinforcement, and maintains a good sealing condition. can be maintained.

In addition, when taking out the contents such as powder or granular material, the strings 4 and 4 at the upper and lower opening ends 2, for example,
If the bag is unzipped, the opening end 2 can be easily opened by extending it, and in order to take out part of the powder or granules and resealing the bag, the upper opening end 2 can be opened as the contents decrease. The bag can be closed in the same manner as described above by increasing the number of times the bag is rolled, folded and folded, and a sealed bag state suitable for the amount of contents can be obtained.

As described above, the present invention provides bag-sealing strings 4, 4, 5, and 5 at the multiple parts formed by folding the upper and lower opening ends 2 and 3 of the upper and lower opening ends 2 and 3 of the cylindrical bag body 1, which can be opened up and down, in a gusset shape on both sides, respectively. Since the bottom part of the bag body 1 is attached to the bag body 1, forming the bottom part and sealing the bag can be done easily and reliably by winding, folding and overlapping the opening end and tying the string, making it easy to use bag making machines such as sewing machines. It is not necessary, and the labor required for bag making and bag sealing can be reduced. In addition, the bag capacity can be arbitrarily and easily adjusted by increasing or decreasing the number of times the opening end is wound, folded, or folded according to the amount of powder or granules to be stored, and a sealed bag state suitable for the amount of contents can be obtained. Can be done. In particular, in the present invention, the string for sealing the bag is attached to the upper and lower opening ends of the cylindrical bag by penetrating the multiple parts formed by the gusset-like folds on both sides from the front and back. It can be easily attached by simply inserting it into the hole that penetrates the front and back sides without requiring any effort.Moreover, since it has multiple parts, the attachment part of the cord has sufficient strength, making it suitable for binding the cord. It can withstand the force of twisting and has excellent durability without any special reinforcement. Therefore, the bag will not be damaged during sealing and opening operations, making it suitable as a bag for use when the contents are gradually removed. It can be used in the same way, and depending on the material of the bag, it can be used repeatedly.
