[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0027] like Figures 1 to 5 As shown, the utility model discloses a vacuum compression bag with a handle strap, which has a series of advantages such as portability, high strength, tear resistance, good sealing, and saving internal space.
[0028] Example 1:
[0029] like Figure 1-Figure 2 The embodiment 1 of the present invention is shown. In this embodiment, the vacuum compression bag comprises a bag body 1 and a handle 2. The bag body 1 constitutes the main structure of the compression bag and is used to accommodate items to be stored.
[0030] The bag body 1 can be made of a material with good flexibility and high airtightness, such as polyethylene (PE), polypropylene (PP), or other polymer materials. The outer surface of the bag body 1 is provided with a fabric layer. The bag body 1 is provided with an opening 11 and a sealing assembly 12 for opening and closing the opening 11. The side wall of the bag body 1 is provided with an air valve assembly 13 for extracting and exhausting air.
[0031] The handle strap 2 is one of the key innovations of this design, and its lower end is connected to the side wall of the bag body 1.
[0032] Preferably, the handle strap 2 is fixed to the connection area by sewing or riveting, which can increase the connection strength and improve the load-bearing capacity.
[0033] This design provides a convenient handle without taking up valuable storage space within the bag. The handle strap 2 can be made of a high-strength textile material such as nylon or polyester. The handle strap 2 is typically in an inverted U-shape, with both lower ends connected to the side walls of the bag body 1. The handle strap 2 can be made long or short as needed; a short one can be carried by hand, while a long one can be worn over the shoulder or on the back.
[0034] The lower end of the handle strap 2 connects to the sidewall of the bag body 1, forming a connection zone. To enhance the sealing performance of this connection zone, the present invention provides a sealing layer 4 on the inner side of the connection zone. The primary function of the sealing layer 4 is to prevent external air and moisture from penetrating into the bag body 1, thereby maintaining a vacuum and dry environment for the items within the bag. The sealing layer 4 can be made of an airtight plastic film or other suitable sealing material to ensure a reliable seal under various environmental conditions.
[0035] In addition to its sealing properties, the sealing layer 4 also enhances the structural strength of the connection area. When the handle strap 2 is subjected to external forces, the sealing layer 4 effectively disperses the pressure applied to the connection area, reducing stress concentration between the handle strap and the bag body, thereby effectively minimizing the risk of tearing or breakage. This dual-function design not only ensures excellent sealing performance in the connection area, but also enhances overall durability.
[0036] In terms of manufacturing process, the sealing layer 4 can be applied by heat sealing, gluing or other connection methods to ensure that it is tightly combined with the bag body 1.
[0037] Furthermore, the sealing component 12 is a sealed zipper, and includes two zipper tapes and a slider. The two zipper tapes are arranged at the opening 11, and the slider is arranged on the two zipper tapes and is used to control the opening and closing of the two zipper tapes.
[0038] Furthermore, the air valve 13 adopts a one-way valve design, which can automatically seal after the air is pumped out to prevent air from flowing back. The air valve assembly 13 includes a valve body, a valve cover and a valve core. The valve body is arranged on the bag body 1. The valve body is provided with a receiving cavity for accommodating the valve core. The bottom of the receiving cavity is provided with an air inlet hole. The valve core can reciprocate along the axial direction of the air inlet hole and is used to open and close the air inlet hole. The valve cover is arranged on the valve body and is provided with an exhaust hole.
[0039] Furthermore, a guide sleeve is provided in the air inlet hole, and a guide column adapted to the guide sleeve is provided on the valve core.
[0040] Furthermore, the air valve assembly 13 is a self-exhausting air valve.
[0041] Example 2:
[0042] like Figure 3-Figure 4 The second embodiment of the present invention is shown. The difference from the first embodiment described above is that, in this embodiment, in order to solve the problem of insufficient connection strength of the handle strap in the traditional design, the present invention innovatively provides a reinforcing interlayer 3 on the inner side wall of the bag body 1, that is, at the position corresponding to the connection area of the handle strap 2. In other words, the reinforcing interlayer 3 is fixedly connected between the connection area and the sealing layer 4. The reinforcing interlayer 3 can be made of the same or similar material as the bag body 1, but the thickness can be appropriately increased; higher strength materials can also be used, such as high-strength textile materials such as nylon and polyester. This design significantly increases the structural strength of the connection between the handle strap 2 and the bag body 1, effectively avoiding the problem of tearing that may occur during use, and greatly improving the product's load-bearing capacity and durability.
[0043] In order to ensure that the reinforcing interlayer 3 does not affect the sealing performance of the compression bag, the sealing layer 4 completely covers the reinforcing interlayer 3, effectively preventing possible air leakage problems and ensuring the normal function of the compression bag.
[0044] In terms of manufacturing, the lower end of the handle strap 2, the corresponding area of the bag body 1's sidewall, and the reinforcing interlayer 3 are secured together by sewing or riveting. This connection method is not only relatively simple to manufacture and reduces production costs, but also significantly increases structural strength. High-strength nylon thread is preferably used for sewing, and the stitching density is increased to ensure a secure connection.
[0045] Regarding the sealing layer 4, this embodiment provides two optional implementations:
[0046] 1) In the first embodiment, the size of the sealing layer 4 is larger than that of the reinforcing interlayer 3 so as to completely cover the reinforcing interlayer 3. The periphery of the sealing layer 4 is fixed to the inner wall of the bag body 1 by gluing or by heat-sealing welding. When gluing, an environmentally friendly strong glue can be selected to ensure the bonding strength without generating harmful gases; when heat-sealing welding is used, a high-frequency heat sealing machine with a frequency of 27.12 MHz can be used, and the welding temperature can be controlled between 130°C and 150°C to obtain the best sealing effect. In terms of materials, the sealing layer 4 is usually made of an airtight, heat-sealable plastic film, preferably the same material as the bag body 1.
[0047] 2) In the second embodiment, the sealing layer 4 is a glue layer directly applied to the inner side of the reinforcing interlayer 3 and its surrounding area. This method can simplify the production process and improve production efficiency. The glue used should have good sealing properties and durability. Polyurethane (PU) glue or silicone glue can be considered.
[0048] Through the above design, the vacuum compression bag of the present invention not only solves the problems of improper handle strap design, weak load-bearing capacity, and easy air leakage in traditional products, but also adopts a relatively simple manufacturing process while ensuring performance, effectively controlling production costs.
[0049] Example 3:
[0050] like Figure 5 The third embodiment of the present invention is shown. Its main difference from the first embodiment lies in that a through-hole 14 is provided in the connection area of this embodiment, allowing the lower end of the handle strap 2 to pass through the through-hole 14 and extend into the bag, where it is fixed to the inner wall of the bag body 1 (e.g., by heat-welding, sewing, or riveting). This design allows the handle strap 2 to better distribute force during use, improving its stability and comfort. Furthermore, the sealing layer 4 effectively seals the portion of the handle strap 2 extending into the bag, thereby preventing air leakage caused by the connection between the handle strap and the bag body.
[0051] The advantage of this design is that by extending the connection position of the handle strap 2 to the inner side of the bag body 1, the load-bearing capacity of the handle strap is further enhanced, making the product safer and more reliable when in use.
[0052] Through the improvements and optimizations of these three embodiments, the vacuum compression bag of the present invention is enhanced in many aspects such as practicality, durability and convenience, making it an ideal choice for consumers to store items.
