Description

Technical Field

[0001] This utility model relates to the field of airtight bag technology, and in particular to an airtight bag. Background Technology

[0002] Airtight bags (vacuum compression bags) are sealed containers used to store clothing, bedding, and other items. They reduce volume and improve storage efficiency by creating a vacuum. Existing airtight bags typically use airtight zippers as the primary sealing structure to ensure a high degree of seal even after the air inside is removed, preventing air backflow. However, existing airtight bags still have the following technical problems regarding ease of use and functional expandability:

[0003] 1. Difficulty opening the zipper and lack of grip support: Because a vacuum seal creates negative pressure inside the airtight bag, causing the bag to adhere tightly to the contents, the zipper is significantly affected by the pressure difference. Users often need considerable pulling force to open the zipper. However, existing airtight bags typically have smooth plastic or composite material surfaces, lacking anti-slip grip structures, leading to the following problems for users during operation:

[0004] One-handed operation is inconvenient: Users usually need to use one hand to pull open the zipper and the other hand to hold the bag to provide counterforce. However, because the surface of the bag is smooth and there is no fixed grip point, it is difficult to apply force steadily, making it difficult to open the zipper, and may even damage the zipper or the bag due to excessive force.

[0005] Slippery: The smooth surface of the bag is more slippery when wet or when hands are sweaty, further increasing the difficulty of handling.

[0006] Currently, some improvement solutions attempt to add anti-slip textures or local protrusions to the surface of the bag, but these designs can only slightly improve the grip experience and do not fundamentally solve the problems of inconvenience in one-handed operation and difficulty in opening the zipper caused by air pressure difference.

[0007] 2. Limited functionality and lack of adaptability as a backpack: Existing airtight bags are primarily designed for storage in suitcases or lockers, with structures that only meet basic vacuum sealing requirements, without considering their direct use as backpacks. Therefore, existing airtight bags have the following limitations:

[0008] Strapless connection structure: Traditional airtight bags do not have pre-reserved installation positions for shoulder straps, so users cannot carry them directly as backpacks, which limits the usage scenarios. Utility Model Content

[0009] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a foldable shower shelf for a shower chair.

[0010] An airtight bag designed for this purpose includes a bag body, which is provided with an airtight zipper and an air valve; the bag body is provided with an extended grip, which is provided with a connecting structure for connecting a shoulder strap.

[0011] Preferably, the extended grip includes an extension fixedly connected to the bag body, and the extension is fixedly connected to a grip handle; the connecting structure is disposed on the extension.

[0012] Preferably, the connection structure includes a receiving space provided in the grip handle, the receiving space for accommodating a shoulder strap connector, the receiving space having an opening, the shoulder strap connector extending from the opening into the receiving space, and a locking element provided within the receiving space for locking engagement with the receiving space.

[0013] Preferably, the locking element is a protrusion disposed within the receiving space, and the strap connector has a locking hole into which the locking element is inserted to restrain the strap connector from remaining within the receiving space.

[0014] Preferably, the grip includes two interconnected handle housings, with a receiving space disposed between the handle housings.

[0015] Preferably, the extension is clamped and fixed between the upper and lower handle housings.

[0016] Preferably, a positioning groove is provided on the wall surface of the handle housing facing the other handle housing, and the extension is embedded in the positioning groove.

[0034] See Figures 1-5 An airtight bag includes a bag body 10, which is provided with an airtight zipper 110 and an air valve 120. The bag body 10 also includes an extended grip 20, which has a connecting structure 200 for connecting a shoulder strap 30. The extended grip facilitates gripping and applying force when the zipper is opened. Simultaneously, the connecting structure of the extended grip can be used to connect a shoulder strap, allowing the user to add a shoulder strap when using the airtight bag as a backpack.

[0035] See Figure 2 The extended grip 20 includes an extension 210 fixedly connected to the bag body 10, and a grip handle 220 is fixedly connected to the extension 210; the connecting structure 200 is disposed on the extension 210. The grip handle 220 is used to increase the grip feel, allowing the user to grip it for easier force to open the zipper. Alternatively, it can be used as a carrying handle, or as a connector to the shoulder strap.

[0036] See Figure 2 and Figure 5The connection structure 200 includes a receiving space 240 disposed in the grip handle 220. The receiving space 240 is used to receive a shoulder strap connector 40. The receiving space 240 is open. The shoulder strap connector 40 can extend from the opening of the receiving space 240 into the receiving space 240. A locking member 250 is disposed in the receiving space 240 for locking and engaging with the receiving space 240.

[0037] See Figure 2 and Figure 5 The locking member 250 is a protrusion disposed in the receiving space 240, and the shoulder strap connector 40 has a locking hole 430. The locking member 250 is inserted into the locking hole 430 to constrain the shoulder strap connector 40 to remain in the receiving space 240.

[0038] See Figure 2 and Figure 5 The grip handle 220 includes two handle housings 221 connected to each other, and the accommodating space 240 is disposed between the handle housings 221.

[0039] Regarding the assembly of the shoulder strap connector 40, during assembly, place the shoulder strap connector 40 between the two handle housings 221, align it with the receiving space 240, and then close the two handle housings 221 so that the shoulder strap connector 40 enters the receiving space 240. At the same time, insert the locking member 250 into the locking hole 430 so that the locking member 250 cannot fall out of the receiving space 240.

[0040] See Figure 5 The shoulder strap connector 40 includes a first connector 410 and a second connector 420 that are rotatably connected to each other. A locking hole 430 is provided on the first connector 410, and the shoulder strap 30 is connected to the second connector 420.

[0041] See Figure 2 and Figure 5 The extension 210 is clamped and fixed between the upper and lower handle housings 221.

[0042] See Figure 2 The handle housing 221 has a positioning groove 230 on its wall facing the other handle housing 221, and the extension 210 is embedded in the positioning groove 230. This design is such that when the two handle housings 221 are closed, the extension 210 and the positioning groove 230 cooperate to constrain the compression member 210 within the handle housing 221, preventing them from separating.

[0043] Furthermore, the upper and lower handle housings 221 are fixedly connected by bolts 260.

[0044] See Figure 2The extension 210 is made of fabric; the bag body 10 is provided with a fastener 50 that is detachably connected to the grip handle 220.

[0045] See Figure 3 The extended gripping member 20 is provided in two parts and is respectively provided on the upper and lower sides of the bag body 10.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
