Abstract
Description
Technical Field
[0001] This utility model relates to a squeeze-venting storage bag that is easy to fold flat and has a good sealing effect. Background Technology
[0002] In daily life, to save home space, we often use storage bags to seal and store clothes, bedding and other items. One common type of storage bag uses a dedicated exhaust valve on one side of the bag body, connected to an air pump to force air out of the bag, thus achieving high compression and creating a large internal vacuum. However, this type of storage bag relies on a dedicated air pump, increasing usage costs and operational specialization. Furthermore, when the bag is not in use and needs to be folded for storage, the protruding, rigid exhaust valve can be very obstructive, making it difficult to fold flat and taking up extra storage space. Another common type of storage bag uses a special exhaust channel to achieve its exhaust function. Its working principle relies on the pressure difference created inside and outside the bag after manual compression, and the adsorption between the bag surface materials to seal the exhaust channel. Although this design eliminates the need for an air pump, its sealing effect is often unsatisfactory. It is easily compromised by changes in external pressure or movement of items, causing the seal to fail and air to seep back into the bag, making it difficult to maintain the compressed state for long periods. Therefore, existing technologies require further improvement and development. Summary of the Invention
[0003] To address the shortcomings mentioned above, this utility model provides a squeeze-vent storage bag that is easy to fold flat and has a good sealing effect.

[0012] The advantages of this utility model over the prior art are as follows: This utility model has a storage structure that is easy to fold flat, occupies little space, and can achieve extrusion and reliable sealing by opening and closing the exhaust cover. The exhaust operation is simple and convenient. Attached Figure Description
[0013] Figure 1 This is a plan view of a squeeze-venting storage bag that is easy to fold flat and has a good sealing effect according to this utility model. Figure 2 for Figure 1 Enlarged view of point A in the middle; Figure 3 for Figure 1 Enlarged view of point B in the middle; Figure 4 This is a three-dimensional view of the exhaust mount involved in this solution. Detailed Implementation
[0014] like Figures 1-4 As shown, an embodiment of this utility model provides a convenient, flat, and well-sealed squeeze-venting storage bag, including a bag body 1. The bag body 1 can be folded into a rectangle or other polygonal shapes; in this embodiment, a rectangle is chosen (e.g., ...). Figure 1(As shown in the figure). In this figure, one side of the bag body 1 is the storage side and the other side is the non-storage side. The bag body 1 has a storage opening 1-1 on the storage side and an opening and closing sealing structure 2 at the storage opening 1-1. The opening and closing sealing structure 2 can be a sealing strip structure, a zipper structure, or other simple fastening mechanism. In this embodiment, a sealing strip structure is selected. That is, the opening and closing sealing structure 2 includes two sets of sealing strips 3 that are provided on the two sides of the bag at the storage opening 1-1 and cooperate with each other, and a sealing clip 4 that is slidably provided on the bag body 1 and used to press the sealing strips 3. When in use, the sealing strips 3 are opened to repeatedly store various items. After storage, the sealing strips 3 can be paired and pressed closed by the sealing clip 4. The operation is simple and convenient, and the sealing performance is good.
[0015] Furthermore, such as Figures 1-4 As shown, in this embodiment, the bag body 1 has an inwardly inclined exhaust side between one of the adjacent non-storage sides. An exhaust assembly 5 is provided on the exhaust side. The exhaust assembly 5 includes an exhaust seat 6 and an exhaust cover 7. The exhaust seat 6 is fixedly connected to the bag body 1 and has an exhaust channel 6-1 that connects the inside and outside of the bag body 1. The exhaust cover 7 is movably connected to the exhaust seat 6 and can move relative to the exhaust seat 6 to open or close the exhaust channel 6-1. By opening and closing the exhaust cover 7, squeeze exhaust and reliable sealing can be achieved. The exhaust operation is simple and convenient. The exhaust assembly 5 is located in the area defined by the outer extension line of the adjacent non-storage side of the exhaust side, and its axis is parallel to the plane of the bag body 1 after folding. This ensures that the exhaust assembly 5 is folded flat with the bag body 1. When the bag body 1 is in the folded storage state, all parts of the exhaust assembly 5 are folded inside to ensure that no parts are exposed, so that the space occupied after folding is small.
[0016] Furthermore, such as Figures 1-4 As shown, the exhaust seat 6 in this embodiment includes a connecting part 6-2 and a connector part 6-3. The outer wall of the connecting part 6-2 is fixedly connected to the bag body 1. The exhaust cover 7 is threadedly connected to the connector part 6-3, and a sealing part 7-1 is provided on the inner side of the end corresponding to the exhaust channel 6-1. Multiple air outlets 7-2 are provided around the sealing part 7-1 on the end wall of the exhaust cover 7. When in use, rotate the exhaust cover 7 until there is a flow gap between the sealing part 7-1 and the exhaust channel 6-1, and the exhaust channel 6-1 and the air outlets 7-2 are connected. The user can vent air outward by squeezing the bag body 1. After venting, rotate the exhaust cover 7 until the sealing part 7-1 is locked into the exhaust channel 6-1, and the sealing part 7-1 blocks the connection between the exhaust channel 6-1 and the air outlets 7-2. The operation is simple and the sealing performance is good.
[0017] Furthermore, such as Figures 1-4As shown, in this embodiment, the upper end of the connector 6-3 is provided with an extension portion 6-4, and the lower outer wall is provided with an external thread portion 6-5. The exhaust cover 7 is provided with an internal thread portion 7-3 corresponding to the external thread portion 6-5. The internal thread portion 7-3 cooperates with the extension portion 6-4 to prevent the exhaust cover 7 from disengaging from the connector 6-3 when it rotates. During assembly, the extension portion 6-4 on the connector 6-3 is forcibly inserted into the internal thread portion 7-3 on the exhaust cover 7, and then the exhaust cover 7 is rotated until the internal thread portion 7-3 is threadedly connected to the external thread portion 6-5 on the connector 6-3, so as to realize the opening or closing of the connection between the exhaust channel 6-1 and the air outlet 7-2.
[0018] Furthermore, such as Figures 1-4 As shown, in this embodiment, the height of the outer wall of the connector 6-3 matches the height of the inner wall of the exhaust cover 7. The end wall of the connector 6-3 is provided with an annular groove 6-6, and a sealing ring 8 is fitted on the annular groove 6-6. The setting of the sealing ring 8 improves the sealing between the connector 6-3 and the exhaust cover 7.
[0019] Furthermore, such as Figures 1-4 As shown, in this embodiment, the connecting part 6-2 is spindle-shaped to facilitate the flat folding of the bag body 1. Multiple connecting grooves 6-7 are provided parallel on the outer side wall of the connecting part 6-2, which increases the heat-fusion connection area between the connecting part 6-2 and the two sides of the bag surface and strengthens the local connection strength. In addition, the lower end of the connecting part 6-2 is provided with an anti-blocking annular protrusion 6-8 to ensure the smooth flow of exhaust.
