[0029] To make the objectives, technical solutions, and advantages of the present invention more apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the present invention shown in and described with reference to the accompanying drawings are merely exemplary, and the present invention is not limited to these embodiments.
[0030] In order to avoid obscuring the present invention due to unnecessary details, the drawings only show structures and / or processing steps closely related to the solutions according to the present invention, while other less relevant details are omitted.
[0031] Combine Figures 1 to 5 As shown, Figure 1 The state corresponding to the following zipper bag 1 when the buckle cover block 42 is removed from the buckle base 41, Figure 4 Corresponding to the state where the fastener cover block 42 of the zipper bag 1 is covered on the fastener base 41 , an embodiment of the utility model provides a zipper bag, which includes a bag body 1 , a concave-convex zipper strip 2 , a zipper head 3 and a fastener 4 .
[0032] The bag body 1 forms a storage space with an opening at the top;
[0033] The concave-convex zipper strip 2 is arranged on the top of the bag body 1;
[0034] The zipper head 3 is clamped on the concave-convex zipper strip 2 and is used to slide back and forth along the length direction of the concave-convex zipper strip 2 from the first side 1a of the bag body 1 to the opposite second side 1b to compress or open the concave-convex zipper strip 2 to close or open the top opening of the bag body 1. When the top opening of the bag body 1 is closed, the zipper head 3 is located on the first side of the bag body 1;
[0035] The fastener 4 includes a fastener base 41 and a fastener cover block 42. The fastener base 41 is fixed to the first side of the bag body 1 and is located below the concave and convex zipper strip 2. The bottom of the fastener cover block 42 is provided with a zipper head accommodating cavity 420a and a bag body sealing groove 420b connected to the two ends of the zipper head accommodating cavity 420a. The fastener cover block 42 is used to seal onto the fastener base 41 and dock with the fastener base 41. The fastener base 41 blocks the zipper head accommodating cavity 420a and the bottom of the bag body sealing groove 420b, so that the zipper head 3 located on the first side 1a is covered in the zipper head accommodating cavity 420a, and the two sides of the zipper head 3 are blocked by the side walls of the zipper head accommodating cavity 420a and limited.
[0036] In the zipper bag provided by the embodiment of the present invention, when the top opening of the bag body 1 is closed, it is only necessary to cover the fastener cover block 42 with the fastener mother seat 41 and dock it. The fastener 4 is used to enclose the zipper head 3 in the zipper head receiving cavity 420a. The zipper head 3 is not exposed, thereby preventing it from being pulled by external forces such as bumps, squeezing, and pulling. At the same time, both sides of the zipper head 3 are blocked and limited by the side walls of the zipper head receiving cavity 420a. Even if the zipper head 3 is affected by the force exerted on the bag body 1 and the concave and convex zipper strip 2 by the objects in the bag, it cannot move through the side walls of the zipper head receiving cavity 420a, effectively preventing the zipper head 3 from accidentally sliding and unlocking, preventing the zipper bag 3 from leaking internal objects or being contaminated by the outside, which may cause inconvenience and loss to the user. When the user needs to open the top opening of the bag body 1, he only needs to remove the fastener cover block 42 on the fastener mother seat 41 and then pull the zipper head 3 toward the second side 1b of the bag body 1.
[0037] Since the zipper pull 3 is generally made of plastic, if the zipper pull 3 is exposed for a long time and is under stress, it is easy for the zipper pull 3 to deform and become difficult to recover. The zipper pull 3 material will age, resulting in poor sealing of the zipper pull 3, and ultimately, a poor sealing effect of the zipper bag. Therefore, in this embodiment, the width of the bag body sealing groove 420b is smaller than the width of the zipper pull accommodating cavity 420a, and is used to clamp the bag body 1 at both ends of the zipper pull 3. In conjunction with the buckle base 41, the zipper pull 3 is blocked from the zipper pull accommodating cavity 420a and the bottom of the bag body sealing groove 420b. The zipper pull 3 has little contact with the outside world within the zipper pull accommodating cavity 420a, and is well protected, which is conducive to extending the service life. In addition, the zipper pull 3 is clamped on the surrounding concave and convex zipper strips 2, making it difficult to ensure the airtightness of the surrounding area. The bag body sealing groove 420b clamping the bag body 1 can further improve the airtightness of the bag body 1.
[0038] In this embodiment, there are two concave-convex zipper strips 2 , and the two concave-convex zipper strips 2 are arranged in parallel.
[0039] As a specific implementation scheme of a docking scheme between the fastener cover block 42 and the fastener mother seat 41, a connecting hole 420c is provided on the bottom surface of the fastener cover block 42 next to the bag body sealing groove 420b, and connecting columns 411 corresponding to the connecting holes 420c are respectively provided on both ends of the top surface of the fastener mother seat 41, so that the connecting columns 411 can be inserted into the corresponding connecting holes 420c.
[0040] As another specific implementation scheme of the docking scheme between the fastener cover block 42 and the fastener base 41, magnetic buckles are respectively provided on the bottom surface of the fastener cover block 42 and the top surface of the fastener base 41 to achieve a quick and stable connection.
[0041] Furthermore, an anti-stripping layer 11 is heat-sealed on the first side 1a and the second side 1b of the bag body 1, respectively. The anti-stripping layer 11 is added to seal both sides of the top opening of the bag body 1, so that the zipper head 3 cannot pass through the anti-stripping layer 11. The anti-stripping layer 11 is used to prevent the zipper head 3 from detaching from the concave and convex zipper strip 2 from the first side 1a and the second side 1b of the bag body 1.
[0042] Specifically, the zipper head 3 and the buckle 4 are made of plastic. The surface of the zipper head 3 is provided with anti-slip grooves 31 to improve the user's hand feeling and facilitate the user to easily pull the zipper head 3.
[0043] In this embodiment, the bag body 1 is a composite film bag body composed of PE and EVA, that is, a composite film bag body composed of polyethylene and ethylene-vinyl acetate copolymer film materials. The PE and EVA composite film can effectively block water vapor and oxygen, has good tensile strength, and is suitable for transportation. The transparent bag body 1 makes it easy for users to observe the items contained inside.

[0045] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
