[0032] The utility model is further described below in conjunction with embodiments.
[0033] Example 1
[0034] In order to solve the problem that the existing packaging bags generally lack sealing mechanisms at the top when in use, and cannot effectively seal the loaded food, and the packaging bags with sealing mechanisms are mostly disposable and cannot be reused, the following solution is disclosed. For details, please refer to Figure 1-Figure 3, the connecting block 111 matches the placement slot 12, the other end of the protective cloth 11 is fixedly connected to the elastic cloth 113, and the other end of the elastic cloth 113 is fixedly connected to the inside of the packaging bag body 1, the other end of the pulling block 121 extends to the inside of the packaging bag body 1 and is fixedly connected to a spring 122 and a card block 123, and the other end of the spring 122 is fixedly connected to the inside of the placement slot 12, the card block 123 matches the card slot 112, one side of the packaging bag body 1 is also fixedly connected to a protective cover 124, and the protective cover 124 and the other side of the packaging bag body 1 are both provided with Velcro 125. When the items are placed in the interior of the packaging bag body 1 and the top of the packaging bag body 1 needs to be sealed, the user can pull the connecting block 111 on the top of the packaging bag body 1, and place the connecting block 111 in the interior of the placement slot 12. , and pushes the connecting block 111. At this time, under the setting of the spring 122 and the trapezoidal surface of the card block 123, the card block 123 is locked with the card block 123 on the connecting block 111, and the sealing effect on the top of the packaging bag body 1 is completed. The user can also move the protective cover 124 so that the Velcro 125 on the protective cover 124 fits with the Velcro 125 on the other side of the packaging bag body 1, and better forms a sealing and leak-proof effect. When it is necessary to take out the items, the protective cover 124 is reset at this time, and then the pulling block 121 is pulled. After the pulling block 121 drives the card block 123 to escape from the inside of the card slot 112, at this time, under the action of the elastic cloth 113, the connecting block 111 is automatically reset, and the packaging bag body 1 is opened, achieving the effect of sealing and leak-proofing the top of the packaging bag body 1, and it can be used multiple times.
[0035] Example 2
[0036] In order to solve the problem that the existing packaging bags often have no protection effect against external forces, which leads to the packaging bags being easily broken during use, and the top handles are often fixed, which makes it inconvenient to use when carrying heavy objects, the following solution is disclosed. For details, please refer to Figure 1 , Figure 4 and Figure 5The inner side of the packaging bag body 1 is fixedly connected with a protective layer 13, and the inner side of the placement groove 12 is fixedly connected with a heat-insulating layer 14, and the inner side of the protective layer 13 is also fixedly connected with a waterproof layer 15. The left and right ends of the cross block 212 are slidably connected with trapezoidal blocks 213, and the trapezoidal blocks 213 are slidably connected to the inside of the placement box 21, and the bottom of the trapezoidal blocks 213 is fixedly connected with an extension cloth 214. When the food is loaded with items, at this time, due to the setting of the protective layer 13, the heat-insulating layer 14 and the waterproof layer 15, the protective layer 13 is composed of soft nylon, which can effectively prevent the external force from scratching the packaging bag body 1, and the protection The warm layer 14 is composed of aluminum foil, which can keep the items inside the packaging bag body 1 warm. The waterproof layer 15 is composed of polypropylene, which can be waterproof. When the user lifts the packaging bag body 1 by the handle 2, under the action of the grip, the pressing block 211 moves to move the cross block 212, and the cross block 212 drives the trapezoidal block 213 to move and then moves the extension cloth 214. At this time, the contact area between the handle 2 and the user's palm will become larger, thereby preventing the hand from being strangled, thereby achieving a certain protective effect on the packaging bag body 1 and facilitating the user's grasping.
[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
