Abstract
Description
Technical Field
[0001] This utility model relates to the field of bags, specifically to a flip-fold bag. Background Technology
[0002] In everyday life, foldable bags are becoming increasingly common. The purpose of foldable bags is to change their shape according to different user needs, so as to meet different requirements. The bag body can switch between folded and unfolded states, making it convenient for users to switch between applications in different scenarios.
[0003] Existing bags, when switching between different states, often only consider the space performance when the bag is folded and stored, while ignoring the convenience of folding the bag. Since there is no waterproof fabric inside the bag, when you need to put an umbrella that gets wet in the rain inside the bag, you cannot put the umbrella inside the bag. As a result, the bag cannot meet more application scenarios and has limitations.
[0004] Patent application number 202322473433.6, published on March 29, 2024, discloses a portable multi-functional bag, comprising: a bag body; a main shoulder strap mounted on the back of the bag body and fixed at both ends to the bottom of the bag body; a length adjustment component threaded onto the main shoulder strap for adjusting its length; at least one expansion section disposed within the bag body, the expansion section being foldable for storage or unfolded within the bag body; and a storage pocket disposed on the back of the bag body, having an independent internal compartment. The main shoulder strap can be adjusted as needed to achieve crossbody, backpack, or single-shoulder use. The expansion section increases the bag's capacity or can be closed to reduce the bag's volume. Furthermore, the bag can be folded for storage, offering advantages of flexibility and portability.
[0005] In the above literature, the bag must first be folded to the size of a storage pouch before the inner compartment can be unfolded, which is a complicated process. If the bag is not folded completely flat, the inner compartment may not be fully covered, resulting in messy storage or the zipper getting stuck. Moreover, the folding direction of the bag is from the outside to the inside, while the unfolding direction of the inner compartment is from the inside to the outside. These two actions are opposite, which can easily cause the inner compartment to get stuck by the folded layer and not be able to be pulled out, making the folding operation troublesome. In addition, the independent inner compartment is located in the cavity of the bag when it is not folded. After items are placed in it, it will occupy the entire cavity area, resulting in less items that can be placed in the cavity. At the same time, the zipper on the inner compartment is set in the horizontal direction of the bag body, which means that for small bags, the horizontal opening size is limited and cannot accommodate more items. Summary of the Invention
[0006] This utility model provides a flip-fold bag that is easy to fold and convenient to put items in.
[0007] To achieve the above objectives, the technical solution of this utility model is: a flip-fold bag, including a bag body, a first storage cavity provided in the middle of the bag body, and a storage part provided on one side of the bottom of the bag body. The storage part is separated from the side of the bag body and the first storage cavity by a dividing layer. The side of the bag body and the dividing layer form the storage cavity. A first zipper assembly is provided on the storage cavity. The first zipper assembly extends from the bottom of one end face of the bag body, through the bottom of the bag body, to the bottom of the other end face of the bag body. The storage part and the first storage cavity are independent of each other. When the bag body changes from an unfolded state to a folded state, the first zipper assembly is opened, and the side of the bag body flips from one side of the bag body from bottom to top to the other side of the bag body. The first zipper assembly is then closed.
[0008] The above design features a storage compartment on one side of the bottom of the bag, with a zipper assembly extending from one bottom of the bag to the other. The first storage cavity is formed by the side of the bag and the dividing layer. When storage is needed, simply fold the front or back side of the bag upwards to cover the other side and zip it up. This eliminates the need to pull out the interlayer or fold both sides of the storage compartment. Furthermore, since the storage cavity and the first receiving cavity are separate, and the opening of the storage cavity is at the bottom, while one side of the storage cavity shares the front or back panel of the bag, placing items into the storage cavity is as simple as unzipping the first zipper assembly on the end face of the bag and inserting items such as umbrellas. This avoids the storage cavity being squeezed by the receiving cavity on the front or back side of the bag, preventing inconvenience in placing items.
[0009] Furthermore, the inner walls of the storage section are all made of waterproof fabric.
[0010] The above design allows damp or wet objects to be placed in the storage compartment. The storage compartment is independent of the first cavity, so water in the storage compartment will not flow into the first cavity, providing good waterproofing. The opening of the storage compartment is located at the bottom of the bag, so when there is water in the storage compartment, it can flow out through the gap of the zipper assembly without affecting other parts of the bag.
[0011] Furthermore, the first zipper assembly includes a first zipper and a double-sided zipper head, wherein the first zipper is engaged with the double-sided zipper head.
[0012] The above setup is designed so that, during the process of packing or unfolding the bag, the second storage fabric needs to be flipped relative to the bag body. That is, during the process of packing or unfolding the main body of the travel bag, the contact surface between the second storage fabric and the first storage fabric changes. The use of a double-sided zipper head allows the first and second storage fabrics to be opened and closed. Therefore, the double-sided zipper head can ensure the functionality of the travel bag during packing and unfolding.
[0013] Furthermore, the starting and stopping ends of the first zipper are located in the middle of the vertical direction of the bag body.
[0014] The above setup places the zipper in the middle of the vertical direction, so that the weight is evenly distributed when folding, avoiding the center of gravity shifting. Since the bag is divided into two parts of equal height, it can be folded easily without having to fold the bag repeatedly.
[0015] Furthermore, the opening of the storage section is positioned downwards.
[0016] With the above configuration, the opening of the first zipper component faces downwards. When a damp or watery object is placed inside the storage compartment, the water inside the storage compartment can flow out under the action of gravity, preventing water accumulation inside the storage compartment. Furthermore, the first zipper component is not easily visible from the front of the bag, increasing the overall aesthetics of the bag.
[0017] Furthermore, the first zipper assembly located on the end face of the bag body is inclined outward and downward at the bottom of the bag body.
[0018] The above configuration, with its tilted first zipper assembly, allows for a greater upward folding length on the front side of the bag, resulting in a larger storage area and easier flipping.
[0019] Furthermore, the front side of the package is provided with a first crease, which is provided along the lateral direction of the package.
[0020] The above design, by creating a first crease on the front side of the bag, facilitates folding when the front side of the bag is turned over.
[0021] Furthermore, the height of the first crease is set to be flush with the height of the starting and ending ends of the first zipper.
[0022] The above design facilitates folding of the bag body at both ends of the first zipper during the flipping process, enabling more reliable folding. Attached Figure Description

[0034] Example 1.
[0035] like Figures 1 to 4As shown, a flip-fold bag includes a bag body 1, a first storage cavity 21 in the middle of the bag body 1, and a storage section 2 on one side of the bottom of the bag body 1. The storage section 2 is separated from the first storage cavity 21 by a dividing layer 22, forming a storage cavity 20 between the side of the bag body 1 and the dividing layer 22. A first zipper assembly 3 is provided on the storage cavity 20, extending from the bottom of one end face of the bag body 1 through the bottom of the bag body 1 to the bottom of the other end face of the bag body 1. A first zipper assembly for closing the first storage cavity 21 is provided at the bottom of the bag body 1. 3. The storage part 2 and the first storage cavity 21 are independent of each other. When the bag body 1 changes from the unfolded state to the stored state, the first zipper assembly 3 is opened, and the side of the bag body flips from one side of the bag body 1 from bottom to top to the other side of the bag body 1. The first zipper assembly 3 is then closed. Since the storage part 2 is provided on the bag body 1, when the bag body 1 needs to be stored, the side of the bag body is first unfolded through the first zipper assembly 3 so that the side of the bag body is away from the dividing layer 22. The bag body 1 is compressed and folded, and then the side of the bag body flips from one side of the bag body 1 from bottom to top to the other side of the bag body 1. The first zipper assembly 3 is then closed to complete the storage of the bag body 1.
[0036] When the bag body 1 needs to be unfolded, the dividing layer 22 is unfolded by the first zipper assembly 3, so that the dividing layer 22 is away from the other side of the bag body 1. Then the dividing layer 22 is flipped to the other side of the first storage cavity 21, so that the bag body 1 is no longer between the side of the bag body and the dividing layer 22. Then the first zipper assembly 3 is used to close the side of the bag body and the dividing layer 22, thus completing the unfolding of the main body of the travel bag. In this embodiment, the storage part is located on the bottom of the bag body near the front side of the bag body, so that the front side of the bag body and the dividing layer form a storage part. In another embodiment, the storage part is located on the bottom of the bag body near the rear side of the bag body, so that the rear side of the bag body and the dividing layer form a storage part.
[0037] The inner walls of the storage section are all made of waterproof fabric. Since the inner walls of the storage section 2 are all supported by waterproof fabric, damp or water-containing objects can be placed in the storage section 2. The storage section 2 is independent of the first cavity 11, so the water in the storage section 2 will not flow into the first cavity 11, and the water-proof effect is good.
[0038] like Figure 2-3As shown, the first zipper assembly 3 is located on one side of the bottom of the bag body 1, including a first zipper 31 and a zipper head 32. The first zipper 31 and the zipper head 32 are engaged and connected. In this embodiment, the zipper head 32 is a bidirectional zipper head. Since the side of the bag body needs to be flipped relative to the bag body 1 during the storage or unfolding process, that is, the contact surface between the side of the bag body and the dividing layer 21 changes during the storage or unfolding process of the travel bag body, the zipper head 32 can be used to open and close the dividing layer 21 and the side of the bag body. Therefore, the zipper head 32 can ensure the functionality of the travel bag during the storage and unfolding process.
[0039] like Figure 2 As shown, the starting and stopping ends of the first zipper 31 are located in the middle of the vertical direction of the bag body 1. The zipper divides the bag body 1 into two parts of equal height. When folding, the weight is evenly distributed between the top and bottom, avoiding the center of gravity shift. Since the bag body 1 is divided into two parts of equal height, folding can be completed with simple operation without having to fold the bag body 1 repeatedly.
[0040] The opening of the first zipper assembly 3 faces downwards. When a damp or watery object is placed inside the storage section 2, the water inside the storage section 2 can flow out under the action of gravity, preventing water accumulation inside the storage section 2. Furthermore, the first zipper assembly 3 is not easily visible from the front of the bag body 1, thus increasing the overall aesthetics of the bag body 1.
[0041] The storage section 2 is located on one side of the bag body 1. When the storage section 2 is located on one side of the bag body 1, that is, when folding, the side of the bag body can easily be based on the dividing layer 21, and only the side of the bag body needs to be flipped. There is no need to flip the dividing layer 21. During the flipping and covering process of the side of the bag body, the zipper piece on the dividing layer will be flipped, thereby realizing flipping and folding, which is convenient for folding.
[0042] like Figure 1 and Figure 2 As shown, a first crease extending in the horizontal direction of the bag body is provided on the front side of the bag body. The first crease 11 is formed by sewing the fabric in the upper and lower directions of the front side of the bag body. The height of the two ends of the first crease 11 is level with the height of the starting and ending ends of the first zipper 31, so that when the zipper head 32 is pulled open, it can be reliably folded along the position of the first crease 11. The first zipper 31 located on both ends of the bag body 1 is inclined to the bottom of the bag body 1, and is inclined downward and outward with the bottom of the bag body 1. This increases the length of the first zipper from the bottom of the bag body 1 to the middle of the bag body, so that the side of the bag body can be covered with a larger area after being turned over.
[0043] The working principle of this utility model is as follows: By providing a storage part 2 on the bag body 1, when it is necessary to store the bag body 1, the front side of the bag body is first unfolded by the first zipper assembly 3, so that the front side of the bag body is away from the dividing layer 21, the bag body 1 is compressed and folded, and then the front side of the bag body is flipped from one side of the bag body 1 from bottom to top to the other side of the bag body 1, and the first zipper assembly 3 is pulled to complete the storage of the bag body 1.
[0044] When it is necessary to unfold the bag body 1, the front side of the bag body will be unfolded through the first zipper assembly 3, so that the front side of the bag body is away from the dividing layer 21. Then, the front side of the bag body will be flipped to the other side of the dividing layer 21, so that the bag body 1 is no longer between the dividing layer 21 and the front side of the bag body. Then, the dividing layer 21 and the front side of the bag body will be closed through the first zipper assembly 3, thus completing the unfolding of the main body of the travel bag.
[0045] Example 2.
[0046] like Figure 5-7 As shown, the only difference between Embodiment 2 and Embodiment 1 is that the first zipper 31 located on both ends of the bag body is set vertically to the bottom of the bag body 1, and the starting end and the stopping end of the first zipper are slightly higher than 1 / 2 the height of the bag body 1, which facilitates the opening and closing of the zipper.
[0047] Example 3.
[0048] like Figure 8-10 As shown, the difference between Embodiment 3 and Embodiment 1 is only that: this embodiment is used for backpacks, and a first zipper assembly 3 is provided around the bottom of the backpack, and a storage part is provided at the bottom of the backpack. The storage part and the first storage cavity of the backpack are formed into two independent cavities through a dividing layer. When storing, the side of the storage part opposite to the dividing layer is the bottom surface of the backpack, and the backpack is folded and covered by flipping the bottom surface of the backpack.
