[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1-7 As shown, this utility model discloses a packaging bag that prevents items from spilling, including a bag body 1, a front handle 2, and a rear handle 3. The bag body 1 has a receiving cavity 11 extending vertically along its length. The bag body 1 includes an opening at the top of the receiving cavity 11. After placing items into the receiving cavity 11 into the bag body 1, the bag can be moved by lifting the front and rear handles 3. A cap 12 is rotatably mounted on the top left side of the bag body 1. The shape and size of the cap 12 are adapted to the opening. The upward projection of the receiving cavity 11 is located on the cap 12, and the cap 12 and the bag body 1 can be connected by Velcro, magnets, or other means. Disassembly: Since the left side of the bag body 1 is fitted with a cover 12, after placing the required items into the receiving cavity 11, the cover 12 is rotated downwards, occupying the opening position. At this time, the upward projection of the receiving cavity 11 falls on the cover 12. After the cover 12 is connected to the bag body 1, without the action of external force, the cover 12 in the opening position can close the opening of the bag body 1, so that the items in the receiving cavity 11 will not spill out. After separating the cover 12 from the bag body 1, the cover 12 is rotated upwards, so that the main body of the cover 12 leaves the opening of the receiving cavity 11, and the items in the receiving cavity 11 can be taken out.
[0027] The bag body 1 is provided with a mounting seat 13 on the left side of the accommodating cavity 11, and the cover 12 is rotatably mounted on the mounting seat 13. The mounting seat 13 is provided with a baffle 131 protruding from the bottom of the cover 12. The baffle 131 abuts against the bottom of the cover 12. When the cover 12 is completely located at the top of the accommodating cavity 11, the bottom of the cover 12 abuts against the baffle 131 of the mounting seat 13, thereby determining the position of the cover 12 on the bag body 1 and facilitating the connection between the cover 12 and the bag body 1.
[0028] Preferably, the right side of the cover 12 is fixedly mounted with a first magic tape 121 by bonding or the like. The bag body 1 is provided with a second magic tape 14 corresponding to the first magic tape 121. After the cover 12 is rotated downward, the first magic tape 121 on the cover 12 abuts against the second magic tape 14 on the bag body 1, thereby further improving the stability of the cover 12 at the opening position. The magic tape design allows multiple uses while being detachable.
[0029] In addition, the bag body 1 is mounted with rubber-made abutting pieces 15 on the front and rear sides of the cover 12. Each abutting piece 15 includes a fixed segment 151 fixed to the bag body 1 and extending leftward and rightward, and a matching segment 152 perpendicular to the fixed segment 151. Each matching segment 152 abuts against the cover 12. Since the abutting pieces 15 are made of rubber, they can deform under an applied force. When the cover 12 needs to be rotated downward to be connected to the bag body 1, the abutting pieces 15 are bent away from the accommodating cavity 11. After the first magic tape 121 is connected to the second magic tape 14, the force applied to the abutting pieces 15 is released, and the matching segments 152 abut against the cover 12, thereby further improving the stability of the cover 12 at the opening position. After the abutting pieces 15 are bent away from the accommodating cavity 11, the cover 12 is separated from the bag body 1, and then the cover 12 is rotated downward to contact the objects in the accommodating cavity 11.
[0030] Each matching segment 152 is provided with an insertion portion 1521 obliquely arranged and inserted into the cover 12. After the cover 12 falls into the opening position, the force applied to the abutting pieces 15 is released, and the insertion portion 1521 on the matching segment 152 is inserted into the cover 12, thereby further improving the connection strength between the abutting pieces 15 and the cover 12, so that the cover 12 can be more stably located in the bag body 1.
[0031] Preferably, each fitting section 152 is provided with a socket 1522, and the cover 12 is provided with a screw hole 122 corresponding to each socket 1522. After the fitting of the fitting piece 15 with the cover 12 is completed, a bolt (not shown in the figure) that is shaped to fit the screw hole 122 is inserted into the socket 1522, and after the threaded fitting of the bolt with the corresponding screw hole 122 is completed, the bolt can be stably positioned between the fitting piece 15 and the cover 12, thereby enabling the stable connection of the cover 12 with the fitting piece, so that the cover 12 cannot be separated from the bag body 1 during the carrying of the bag body 1, and the bolt is not removed, thereby preventing the articles from being easily spilled, and after the bolt is removed by being reversely rotated, the fitting pieces 15 are pried to separate the insertion part 1521 from the cover 12, and then the cover 12 is turned upward by applying a force to the cover 12 to separate the cover 12 from the bag body 1, so that the cover 12 can be contacted to the accommodating cavity 11 of the bag body 1.
[0032] Preferably, the cover 12 is integrally formed with a contact plate 123 on the right side thereof, and the contact plate 123 provides a contact position for applying a force to the cover 12 to turn the cover 12, thereby facilitating the turning of the cover 12.
[0033] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
