Description

The closing structure of the paper bag}

The present invention relates to a finishing structure of the wrapping paper, and more specifically, by configuring the length of the pair of inlays, middle and outer edges facing the opening side of the wrapping paper, it is easy to bend the molding of the wrapping paper. The present invention relates to a finishing structure in which an opening tape is closely adhered to improve the airtightness of a wrapping paper.

In general, in packing various items such as sugar, feed, milling, grain, cement, etc., three or four layers of kraft paper should be used to make a paper bag that can withstand the weight according to the packaging. Easily open type is used in the closed part and the other end of the open part to close easily when you want to use the goods inside the wrapping paper.

The easy open type opening structure is made by attaching the opening tape to the end of the bent wrapping paper, and then pulling the end of the extended opening tape by hand to use the packaged contents. Refers to a structure where the reinforcement paper is cut by the opening tape and can be opened without the use of other tools.

1 and 2 is a conventional design, the conventional wrapping paper is formed in the sealing portion 7 and the other end of which the one end is sealed so that the opening is made possible. The upper end of the wrapping paper is composed of a pair of inlays (1) (1a), a middle finger (2) (2a), the outer surface (3) (3a) facing both sides of the folded portion (4), the pair of inlays (1) ) 1a, middle finger (2) (2a), and folded in succession twice in the longitudinal direction so that the ends of the outer surface (3) (3a). The open tape 6 adhered to the reinforcement paper 5 is long attached to the boundary line between the bent portion of the kraft paper and the portion where the wrapping paper abuts. On the other hand, the bending thickness H of the superimposed kraft paper formed when the edge of the kraft paper is folded twice in order to capture the opening side is 5 mm or more. Twelve overlapping kraft paper is folded thickness.

As the number of sheets of kraft paper to be folded when folding the overlapping kraft paper as described above, the bending molding of the wrapping paper is difficult, the productivity is lowered, the product defective rate increases. In addition, the thicker the bending thickness H of the overlapped kraft paper is, the more difficult it is to accurately attach the tear tape 6 to the boundary line where the bent portion and the wrapping paper come into contact with each other. The contents packed through the hollow parts c, d, and e were leaked to the outside, and thus, the transport or storage of the packing paper was inconvenient.

Therefore, while maintaining the finish strength of the opening of the wrapping paper as conventional, it is easy to bend the molding of the wrapping paper, the development of the devised to eliminate the hollow portion that the packaged contents are leaked to the outside has been desired.

The present invention is to solve the above-described problems, and more particularly, to the bending structure of the wrapping paper is easy, the open tape is closely attached to the finishing structure of the wrapping paper to improve the airtightness of the wrapping paper.

The purpose of the above-mentioned object is to configure the length of the pair of inlays, middle and outer edges facing the opening side of the wrapping paper differently, and finish by adding a reinforcing paper with an opening tape to wrap the bent portion after folding the end of the kraft paper at least one or more times. It can be achieved by the closing structure of the opening.

Figure 7 is a perspective view showing a state in which the opening of the wrapping paper is closed, Figure 8 is a partially enlarged side cross-sectional view of Figure 7, after folding the end of the kraft paper in the longitudinal direction at least one or more times, the opening tape (60) Attach the reinforcement paper 50 with) to close the opening.

The left and right sides of the folded portion 40 are formed with inlays 10 and 10a, middle and middle portions 20 and 20a, and outer surface 30 and 30a which form a step so that the lengths of the ends are different from each other. The kraft paper overlapping the right side of the fold part 40 is called one side, and the kraft paper configured to overlap the left side of the foldable part 40 is called the other side.

First fold the ends of the kraft paper in the longitudinal direction. When folded once, the ends of the overlapped kraft paper are folded to one side. The inlay 10, 10a is folded so that the other end edge 31a faces vertically with the one end edge 31 in the unfolded state, and at the same time, the other end edge 21a is one end edge 21 Are folded side by side to face vertically). In fact, only two sheets of the folding end 21a and the outer end 31a of the other side of the kraft paper are folded, so that the bending of the kraft paper is facilitated.

Fold the top of the folded kraft paper in the longitudinal direction again. The outer surface end 31 of one side is bent and folded as a predetermined length. Thus, six sheets of overlapped kraft paper are folded on one side and the other side.

As the kraft paper is folded two times in a row as described above, the raft paper is folded two times when the first folding, and six sheets when the second folding. Therefore, the bent end folded thickness H 'is thinly formed within 3mm, the thickness of the six overlapping kraft paper.
