Description

Technical Field

[0001] The utility model relates to the technical field of compression bags, in particular to a compression bag with a handle. Background Art

[0002] Vacuum compression bags currently on the market come in a variety of designs, but the vast majority lack convenient handles. This lack of design creates significant inconvenience during daily use. Typically, users must grasp the edges of vacuum compression bags with both hands when carrying and organizing them, which is both laborious and difficult to grasp.

[0003] In the few vacuum compression bags equipped with handles, the handles are often formed by holes cut directly into the bag body. This design still presents numerous problems. First, the weight of the bag can cause the handle to pinch the hand during use, leading to discomfort or even pain when carrying it for extended periods. Second, the hole concentrates stress when bearing weight, making it prone to deformation and tearing, reducing the bag's durability and load-bearing capacity. Furthermore, the hole structure also has manufacturing flaws that can easily compromise the bag's seal, compromising the vacuum compression effect.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0038] 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.

[0039] Please refer to Figures 1 to 8 The utility model provides a compression bag with a handle, which mainly includes a bag body 1, a sealing component 15, an air valve component 16 and a handle 2.

[0040] Furthermore, the bag body 1 is composed of a front membrane 11 and a rear membrane 12, which are fixed together at the periphery by welding to form a welding strip 13. The welding strip 13 not only ensures the sealing of the bag body, but also provides sufficient strength to withstand the weight of the internal items and the pressure during vacuum compression.

[0041] An opening 14 is provided on one side of the bag body 1 without the handle 2 for placing and removing items. To ensure a good sealing performance, a sealing component 15 is provided at the opening 14. The sealing component 15 ensures that a good sealing effect is maintained even in a compressed state.

[0042] In order to achieve the vacuum compression function, an air valve assembly 16 is provided on the side wall of the bag body 1. The air valve assembly 16 is used for pumping and exhausting air. Its design takes into account ease of operation and reliability to ensure that no air leakage occurs during use.

[0043] A notable feature of this utility model is the design of the embedded handle 2. The handle 2 is annular (with a lifting hole 22 in the center for the user's finger to pass through for lifting) and is located at the edge of the bag body 1. The inner wall of the handle 2 extends to both sides to form a lifting portion 21. A connecting portion 23 is provided around the periphery of the handle 2, surrounding the outer side of the lifting portion 21. The connecting portion 23 is typically secured to the bag body 1 by welding (such as heat press welding or ultrasonic welding) to form an airtight structure.

[0044] The lifting portion 21 is designed for user comfort. Its front and rear sides extend forward and backward, respectively, protruding from the connecting portion 23. In other words, the thickness of the lifting portion 21 is not less than that of the connecting portion 23. This design gives the lifting portion 21 a certain width, making it comfortable for the user to hold and grip, reducing the discomfort that may arise from prolonged use.

[0045] Preferably, the connecting portion 23 is in the form of a sheet, which is sandwiched between the front diaphragm 11 and the rear diaphragm 12 and welded to them respectively to form a stable and sealed structure. The connecting portion 23 is usually made of plastic.

[0046] Further preferably, at the location of handle 2, welding strip 13 is designed with a C-shaped weld section 131 that partially surrounds handle 2. The opening of C-shaped weld section 131 faces outward, cleverly enhancing the sealing performance of the handle. With this design, even if the handle 2 is torn, it is protected by C-shaped weld section 131, preventing air leakage.

[0047] Furthermore, the opposite sides of the front film 11 and the back film 12 are both provided with a puncture-resistant layer, which is made of a puncture-resistant material such as PA, PET, or OPP.

[0048] Furthermore, a fabric layer is provided on both the front membrane 11 and the rear membrane 12. The fabric layer can improve the bag's tensile strength and structural strength.

[0049] Furthermore, in order to solve the problem of possible bag body welding failure, a blank area 231 is designed at the outermost periphery of the connecting portion 23. This detailed design effectively improves the durability of the product.

[0050] Further, such as Figure 7 (Example 5) and Figure 8 As shown in (Example 6), the welding area of ​​the connecting portion 23 and the bag body 1 adopts embossing welding technology to form a unique embossing pattern 232. Figure 6 The flat welding and embossing welding shown in (Example 1) have the following advantages:

[0051] -Increase welding area to improve sealing strength and reliability.

[0052] - The texture helps distribute stress and reduce the risk of seal rupture.

[0053] - Improve the aesthetics of the product and increase its visual appeal.

[0054] Further, in Example 6 ( Figure 8 ), the concave-convex texture of the embossed pattern 232 gradually becomes shallower from the inner ring to the outer ring of the connecting portion 23. This gradual structure ensures the firmness of the internal welding and avoids the problem of the bag body being damaged by the excessively deep concave-convex texture on the outer periphery.

[0055] According to different usage requirements, the handle 2 can be set on one or more sides of the bag body 1. Specifically:

[0056] -Example 1 ( Figure 1): A handle 2 is provided on one side of the bag body.

[0057] -Example 2 ( Figure 2 ): A handle 2 is provided on the other side which is different from the first embodiment.

[0058] -Example 3 ( Figure 3 ): A handle 2 is respectively provided on two opposite sides.

[0059] -Example 4 ( Figure 4 ):Handles 2 are provided on three sides.

[0060] This flexible design allows manufacturers to choose the most suitable handle configuration according to different usage scenarios and user needs.

[0061] Furthermore, the sealing assembly 15 includes a first bone bar and a second bone bar, the first bone bar and the second bone bar are arranged at the opening 14, the side of the first bone bar is provided with a protrusion, and the side of the second bone bar is provided with a recess for the protrusion to be inserted into. Specifically, the sealing assembly 15 is actually a sealing zipper.

[0062] Furthermore, the air valve assembly 16 includes a valve body, a valve cover and a valve core. The valve body is provided with a accommodating cavity for accommodating the valve core, and a through hole is provided at the bottom of the accommodating cavity. The valve cover is provided with an exhaust hole and is removably installed on the valve body. The valve core can move along the axial direction of the valve body to close the through hole.

[0063] Furthermore, a guide sleeve is provided in the through hole, and a guide column adapted to the guide sleeve is provided on the valve core.

[0064] For the specific structure of the air valve assembly 16, please refer to the patent CN201720026790.X previously applied for by the applicant.

[0065] Furthermore, the air valve assembly 16 can also be another embodiment: the air valve assembly 16 includes a first rubber strip and a second rubber strip arranged side by side between the front diaphragm 11 and the rear diaphragm 12, and the first rubber strip, the second rubber strip and the bag body 1 form an exhaust channel, and the exhaust channel has an air inlet and an exhaust port at both ends respectively.

[0066] For the specific structure of the air valve assembly 16, please refer to the patent CN201720244947.6 previously applied for by the applicant.

[0067] To sum up, the utility model successfully solves the shortcomings of existing vacuum compression bags in terms of portability, comfort, load-bearing capacity and sealing performance through innovative embedded handle design, diversified handle layout, sophisticated welding technology and thoughtful detail consideration, providing users with a storage solution that is both practical and beautiful.
