[0034] See also Figures 1 to 8 , the utility model provides a technical solution:

[0035] A zipper-sealed compression bag comprising:

[0036] The bag body 1 has an opening 13;

[0037] A zipper assembly 2, comprising a zipper head 4 and zipper teeth 3, wherein the zipper teeth 3 are sewn on both sides of the opening 13, and the zipper head 4 is used to engage or disengage the zipper teeth 3 to close or open the opening 13;

[0038] The inner sealing structure is located at the opening 13 and is closer to the inner cavity of the bag body 1 than the zipper assembly 2.

[0039] The inner sealing structure is used to seal the opening 13 in an interference fit manner after the opening 13 is closed and to release the seal when the opening 13 is opened.

[0040] Specifically, the inner sealing structure includes sealing strips 7 located on either side of the opening 13. A slider 5 with a groove 28 is located below the zipper pull 4, which is used to flexibly clamp the two sealing strips 7 together in an interference fit. One of the sealing strips 7 has an elastic ridge 9 running along its long edge, while the other sealing strip 7 has a groove 10 that matches the ridge 9 and is used to clamp the ridge 9. The diameter of the ridge 9 is slightly larger than the groove opening of the groove 10.

[0041] The bag body 1 of this utility model is made of 300D Oxford cloth, coated / laminated with a 0.05mm thick TPU film. Oxford cloth is relatively wear-resistant, providing excellent durability for the bag body 1. The size of the compression bag can be customized, such as 50cm × 70cm × 90cm, which can hold a certain amount of clothing. The TPU film provides waterproof and moisture-proof properties. The zipper assembly 2 allows the opening 13 of the bag body 1 to be closed and opened, effectively protecting the items inside.

[0042] The present invention can seal the opening 13 at the same time when the zipper assembly 2 is used to close the opening 13. Figure 4 and Figure 6 As shown, when the zipper pull 4 is pulled, the slider 5 with the groove 28 is also driven, and the slider 5 is pre-engaged with the two sealing strips 7. In this way, the two sealing strips 7 pass through the groove 28 of the slider 5 and can be squeezed by the slider 5, thereby approaching each other and achieving a clamping. Because the two sealing strips 7 are closer to the opening 13 and located on the inner side, they are closer to the bag cavity of the bag body 1 than the zipper pull 4. On the one hand, the two sealing strips 7 can maintain a good sealing performance after being clamped, and on the other hand, the two sealing strips 7 (and the inner layer 8) can be protected.

[0043] In the present invention, when the two sealing strips 7 are clamped by the slider 5, the convex strips 9 can be clamped and matched with the groove 10 due to the presence of the convex strips 9. Since the diameter of the convex strips 9 is slightly larger than the groove opening of the groove 10, the two are clamped in an interference fit manner, which can not only effectively prevent the two sealing strips 7 from detaching after the bag body 1 is vacuumed, but also ensure that there is no gap in the sealing part, with good sealing / air tightness, and can make the bag body 1 have good sealing.

[0044] Specifically, the bag body 1 with the opening 13 comprises two layers: an outer layer 6 sewn to the zipper teeth 3, and an inner layer 8 sewn to the sealing strip 7. One end of the opening 13 has a sealing member 11 that matches the shape and size of the inner guide post of the zipper slider 4. The sealing strip 7 is slightly shorter than the zipper teeth 3, and the two ends of the sealing strip 7 are glued together.

[0045] The utility model, such as Figure 4 As shown, the outer layer 6 is sewn to the zipper teeth 3, and the sealing strip 7 is sewn to the inner layer 8, thus forming an inner and outer layer. The outer layer is the movable space of the zipper head 4, and the inner layer is the movable space of the slider 5. It should be noted that after the two sealing strips 7 are clamped together by the slider 5, thereby sealing the opening 13, the zipper head 4 is opened again. At this time, the slider 5 can return along the original path, but the two sealing strips 7 are still in a clamped and closed state. It is necessary to first allow air to enter the bag body 1, and then apply a certain pulling force to pull the two sealing strips 7 together, so that the protrusion 9 is pulled out of the groove 10 to open the opening.

[0046] In the present invention, after the slider 5 is used to clamp the two sealing strips 7, the convex strip 9 can be tightly matched with the groove 10, thereby sealing the opening 13. When the air in the bag body 1 is extracted and the items are stored, the seal (opening 13) can be folded or bent and can ensure good airtightness.

[0047] The utility model, such as Figure 3 and Figure 5As shown, the two sealing strips 7 are glued together at both ends. The length of the sealing strips 7 is slightly shorter than the length of the zipper teeth 3. This is to prevent the opening 13 from not being completely sealed by the two sealing strips 7 after the zipper slider 4 is fully pulled into place. The length d of the sealing strips 7 is the same as the length of the opening 13. The sealing strips 7 can be made of TPU, TPE, silicone, etc.

[0048] In the present invention, the sealing member 11 can well cooperate with the bottom plane and the internal guide column of the T-shaped zipper head 4. The end corresponding to the sealing member 11 has a zipper head (not shown in the figure), which ensures the sealing of both ends when the zipper is closed.

[0049] As an optional solution, a positioning module is integrated into a corner of the bag body 1. This embedded positioning module (GPS module) allows users to locate the compression bag in real time via a mobile app using Apple's my Find feature, further enhancing loss prevention. The bag connects to the user's mobile device, such as an iPhone, via Bluetooth, and uses Apple's my Find app for positioning. This greatly facilitates users' ability to find lost compression bags.

[0050] Specifically, the bag body 1 is provided with an air valve 12, which includes a valve seat 14 and a valve core 15 mounted on the valve seat 14. The valve core 15 and the valve seat 14 slide together to seal the bag body 1 from the outside. The top of the valve seat 14 has a top air port 22, and the valve seat 14 has an inner cavity 20. There is a gap 26 between the inner cavity 20 and the top air port 22. The valve seat 14 located at the bottom of the inner cavity 20 has a bottom air port 23. The valve core 15 includes a support section 16, an end cover 17 located at the top of the support section 16, and a first blocking section 18 located at the bottom of the support section 16. The support section 16 passes through the gap 26, and a second blocking section 19 is provided below the end cover 17. The gap 26 has a through groove 21 that cooperates with the second blocking section 19. An air passage 25 is provided between the first blocking section 18 and the inner cavity 20. The bottom of the inner cavity 20 also has a bottom sealing portion 24, and the bottom side of the first sealing portion 18 has a boss 27 that cooperates with the bottom sealing portion 24. The opening diameter of the top gas port 22 is larger than the diameter of the end cover 17, and the depth of the top gas port 22 is greater than the thickness of the end cover 17. The top gas port 22 is also equipped with a plug cover (not shown in the figure).

[0051] In the present invention, after putting an appropriate amount of clothes in the bag body 1, the opening 13 is sealed. After sealing, the bag body 1 needs to be vacuumed. At this time, the air is exhausted by inserting the exhaust pipe of the exhaust equipment into the top air port 22 and tightening it. When exhausting, the valve core 15 moves upward under the action of suction, so that the second blocking part 19 is separated from the through groove 21, and at the same time, the first blocking part 18 is separated from the bottom air port 23, releasing the seal of the bottom air port 23 and separating the boss 27 from the bottom blocking part 24. In this way, all three seals are released, so that the gas in the bag body 1 can enter the air channel 25 from the bottom air port 23 and finally be exhausted from the top air port 22 through the through groove 21, thereby realizing that the air in the bag body 1 is exhausted. After the air is evacuated, the pressure inside the bag body 1 is greater than the external pressure, so the valve core 15 is forced to move downward. Since the inner diameter of the through groove 21 is set to be larger at the top and smaller at the bottom, when the second blocking portion 19 moves downward to the gap 26, it stops at the position where it cooperates with it and cannot move downward any further, so that the second blocking portion 19 and the through groove 21 are tightly connected. At the same time, the bottom blocking portion 24 and the boss 27, and the first blocking portion 18 and the bottom air port 23 are resealed. The end cover portion 17 does not protrude beyond the top air port 22, so that the closed air valve 12 does not have any protrusions, preventing the bag body 1 from being punctured or broken by protrusions. The number of through grooves 21 is several, such as 2, evenly distributed on the gap 26. The shape of the bottom blocking portion 24 can be annular. After the air is evacuated, the valve core 15 of the valve seat 14 is completely sealed, and the top air port 22 is blocked with the plug cover, leaving no leaks.

[0052] The support section 16 can realize the up and down movement of the entire valve core 15 and can also increase the strength of the valve core 15 (air valve 12). Moreover, due to the interval 26, the valve core 15 can only move up and down on the valve seat 14 to prevent the user from falling out when misoperating.

[0053] The bag body 1 adopts the method of using the valve core 15 in conjunction with the valve seat 14 to make the operation of pumping and stopping air more convenient. The valve core 15 can automatically rise when pumping air and automatically reset when stopping air, so that pumping and stopping air do not require manual operation, which is more convenient to use and has a better sealing effect.

[0054] The utility model is novel, and the bag body 1 is provided with an air release port.

[0055] The present utility model, the undescribed parts are prior art.
