[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] Embodiment 1
[0016] like Figure 1-2As shown, the first embodiment discloses a rectangular packaging bag that can be tied and placed vertically, comprising: a packaging bag body, which, in an unfolded state, comprises a left bag body 1, a rear bag body 2, a right bag body 3, a front bag body 4, and a lower bag body 5 arranged from left to right in sequence, the upper part of the inner wall of the left bag body 1 is sealed with the upper part of the inner wall of the left section of the rear bag body 2 and the front bag body 4 respectively by hot-melt connection, the upper part of the inner wall of the right bag body 3 is sealed with the upper part of the inner wall of the right section of the rear bag body 2 and the front bag body 4 respectively by hot-melt connection, and the two middle sections of the rear bag body 2 and the front bag body 4 are sealed. The upper parts of the inner walls are sealed by hot-melt connection, the front and rear sides of the left bag body 1 and the right bag body 3 are sealed with the left and right sides of the rear bag body 2 and the front bag body 4 respectively by hot-melt connection, the sides of the bottom of the left bag body 1, the rear bag body 2, the right bag body 3 and the front bag body 4 are sealed with the four sides of the lower bag body 5 respectively by hot-melt connection, the upper part of the outer wall of the front bag body 4 is bonded with a bendable metal tying strip A by a hot-melt strip, the lateral width of the metal tying strip is greater than the lateral width of the front bag body 4, and the width of the hot-melt connection on the side of the packaging bag body is 0.5 cm.
[0017] Based on the above structure, Figure 1-2 As shown, when in use, tear off the packaging bag body part on the upper side of the metal tying strip A, take out the items in the packaging bag body, and when the packaging bag body needs to be re-tied, first pinch the packaging bag body at the metal tying strip A to keep the inner wall of the packaging bag body in contact, then drive the packaging bag body to rotate backward for several circles through the metal tying strip A, then pull the metal tying strip A upward to tighten the packaging bag body stacked around the metal tying strip A, and then bend the metal tying strips A on both sides of the packaging bag body to the front side of the packaging bag body, so as to achieve the effect of tying the packaging bag body;
[0018] Since the side of the packaging bag body is hot-melt connected, the overall hardness of the side of the packaging bag body is increased, thereby forming a frame on the side of the packaging bag body. At the same time, since the width of the hot-melt connection is 0.5 cm, the stress surface of the frame formed on the side of the packaging bag body is increased, thereby allowing the packaging bag body to be placed vertically.
[0019] Further, such as Figure 3 As shown, in order to increase the force strength and rigidity of the side connection of the packaging bag body, the hot-melt connection of the packaging bag body is hot-melt connected with a reinforcing rib array 6 composed of hot-melt strips.
[0020] Further, such as Figure 1-3 As shown, in order to facilitate hanging of the packaging bag body, two hanging interfaces 7 are correspondingly provided on the two inner walls of the middle sections of the rear bag body 2 and the front bag body 4 .
[0021] Embodiment 2
[0022] like Figure 4-5As shown, since the packaging bag body is flexible, after the packaging bag body is opened, the opening of the packaging bag body will be in an inwardly contracted state due to the flexible setting. This state will cause people to need to insert two fingers of one hand into the packaging bag body during the process of filling the items into the packaging bag body, and stretch the opening of the packaging bag body outward to facilitate the subsequent entry of the items into the packaging bag. This operation method undoubtedly results in one of the hands of people being restricted during the process of filling the items. Therefore, in order to increase the convenience of secondary filling of the packaging bag body after opening, while maintaining the secondary sealing function of the packaging bag body, Example 2 discloses a tieable vertically placed rectangular packaging bag with different technical features compared with Example 1. The different technical features are that a bendable annular metal tie strip B is bonded to the top of the inner wall of the packaging bag body in the sealed state through a hot-melt strip.
[0023] Based on the above structure, Figure 4-5 As shown, before putting the articles into the packaging bag body, put both hands into the left and right ends of the packaging bag body, and use the fingers to apply an outward force to the annular metal tying strips B on the inner walls of the rear bag body 2 and the front bag body 4, so that the annular metal tying strips B on the inner walls of the rear bag body 2 and the front bag body 4 are relatively separated, and at the same time, the annular metal tying strips B on the inner walls of the left bag body 1 and the right bag body 3 are gradually stretched until the opening of the packaging bag body is fully opened. The annular metal tying strips B on the inner walls of the left bag body 1 and the right bag body 3 support the rear bag body 2 and the front bag body 4 through their own hard force, so that the opening of the packaging bag body is always kept in an open state, and then the hands are withdrawn, and the articles are put into the packaging bag body;
[0024] like Figure 5 As shown, when the state of the items in the packaging bag body requires re-tying, both hands are inserted into the packaging bag body, and the annular metal tying strips B on the inner walls of the left bag body 1 and the right bag body 3 are folded outward along the center line. During the folding process, the annular metal tying strips B on the inner walls of the rear bag body 2 and the front bag body 4 are moved to the opposite side by the pulling force generated by the annular metal tying strips B on the inner walls of the left bag body 1 and the right bag body 3 until they fit together. At this time, the annular metal tying strips B form a long strip until both ends of the long strip of annular metal tying strips B are pinched with both hands and rotated for several weeks. Then, the long strips of annular metal tying strips B on both sides of the front bag body 4 are folded and buckled on the outer wall of the front bag body 4 or the outer wall of the rear bag body 2. The bottom end of the long strip of annular metal tying strips B always remains downward during the rotation of the packaging bag body.
[0025] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
