Description
Technical Field
[0001] This utility model relates to the field of daily necessities technology, and in particular to a storage bag with a detachable inner bag. Background Technology
[0002] Storage bags, as a common daily necessity, are widely used for organizing and carrying items such as clothing, stationery, electronic products, and travel goods. During travel, sports, or daily use, users often need to store clean items and items waiting to be washed at the same time, or need to store dry and wet items separately to avoid cross-contamination or moisture damage.
[0003] Currently, storage bags on the market typically employ a compartmentalized design, using internal dividers or pockets to categorize and store items. However, most of these dividers are fixed and cannot be individually removed. When users store dirty, damp, or smelly items (such as clothes after exercise, wet towels, etc.), stains and moisture can easily remain inside the compartments. Since the dividers cannot be removed for washing, users must clean the entire bag, which not only increases the workload but may also cause wear and tear on the fabric, damage to zippers, or deformation of the internal structure due to frequent washing, thus affecting the bag's lifespan.
[0004] Therefore, existing storage bags need to be improved to solve the problem that their compartment structure cannot be disassembled and washed individually, resulting in inconvenient cleaning and easy damage to the bag body.
[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0047] This utility model's detachable inner bag storage bag, through its innovative modular design, fundamentally solves the problems of inconvenient cleaning and easy damage of traditional storage bags.
[0048] See Figure 1 The detachable inner bag storage bag provided by this utility model includes:
[0049] The main package 1 has an inner cavity 103 and a secondary pocket opening 101 that connects the inner cavity 103 to the external space of the main package 1.
[0050] A detachable inner bag 2 is located inside the secondary bag opening 101 and is detachably connected to the main bag body 1.
[0051] A secondary bag cover 3 is located outside the secondary bag opening 101 and is closable and connected to the main bag body 1.
[0052] The secondary bag cover 3 has an open state where the secondary bag opening 101 is opened to expose the detachable inner bag 2; and a closed state where the secondary bag opening 101 is closed to cover the detachable inner bag 2.
[0053] The detachable inner bag storage bag provided in this embodiment works as follows:
[0054] (1) Store by category:
[0055] After opening the secondary pocket cover 3, the user can put clean clothes and other regular items into the inner cavity 103 of the main bag body 1, and put dirty or damp items (such as dirty clothes, wet towels, sneakers, etc.) into the detachable inner pocket 2.
[0056] Then, the secondary bag can be closed to cover 3.
[0057] (2) Quick disassembly
[0058] After arriving at the hotel or home, users can simply open the secondary pocket cover 3 and remove the removable inner pocket 2 to take out the removable inner pocket 2 and any dirt or moisture inside it from the bag cavity 103 for cleaning, without touching any other items inside the main bag body 1.
[0059] Understandably, the removable inner pocket storage bag improves upon the traditional fixed compartment by replacing it with an independently detachable inner pocket 2. When users store dirty or damp items, they can simply open the secondary pocket cover 3 to remove the removable inner pocket 2 for cleaning, avoiding frequent contact between the entire main bag body 1 and water and cleaning agents. This design not only significantly improves cleaning efficiency but, more importantly, effectively protects vulnerable parts of the main bag body 1 such as zippers and seams, significantly extending the lifespan of the removable inner pocket storage bag.
[0060] Therefore, the detachable inner bag storage bag provided by this utility model can effectively solve the problem that the partition structure of existing storage bags cannot be disassembled and cleaned separately, resulting in inconvenient cleaning and easy damage to the bag body.
[0061] In this embodiment, the detachable inner pocket 2 is detachably connected to the main bag body 1 via an inner zipper 4 with a ring structure. The ring structure design of the inner zipper 4 ensures that the detachable inner pocket 2 can be completely disassembled and removed. Furthermore, the main bag body 1 and the secondary pocket cover 3 are detachably connected to the main bag body 1 via an outer zipper 5 with a U-shaped structure. After opening the outer zipper 5, the inner zipper 4 can be exposed.
[0062] It should be noted that the zipper connection is only one of many detachable connection methods. In some other embodiments, the detachable inner pocket 2 and the main bag body 1, and the main bag body 1 and the secondary pocket cover 3 can also be connected by other detachable components such as Velcro, buttons, and snap fasteners. This utility model does not limit this.
[0063] In this embodiment, the outer material of the removable inner bag 2 is the same as the inner wall material of the inner cavity 103 of the bag, so as to prevent friction between different materials from causing debris to be generated inside. The inner side of the removable inner bag 2 is provided with a waterproof layer, such as a silicone layer or a waterproof coating, to prevent sewage or other contaminants in the removable inner bag 2 from passing through the removable inner bag 2 and contaminating other clean items in the inner cavity 103 of the bag.
[0064] In this embodiment, the main bag body 1 is further provided with a main bag opening 102 that connects the inner cavity 103 of the bag to the outer space of the main bag body 1; wherein, the main bag opening 102 is isolated from the inner space of the detachable inner bag 2.
[0065] It should be noted that if the main bag opening 102 is not provided, the clean items in the bag cavity 103 can only be taken out through the secondary bag opening 101 after the secondary bag cover 3 is opened and the removable inner bag 2 is removed.
[0066] With the addition of the main bag opening 102, there is no need to open the secondary bag cover 3. Simply open the main bag opening 102 to directly access clean items in the inner cavity 103 of the bag, further improving the convenience and practicality of the detachable inner bag storage bag.
[0067] Optionally, the inner and / or outer sides of the secondary pocket cover 3 are provided with an elastic mesh 6, which, together with the secondary pocket cover 3, encloses an inner storage space. Small items, such as gym membership cards or ping-pong balls, can be placed in the inner storage space, where the elastic mesh 6 uses its own elasticity to press and secure them.
[0068] In this embodiment, the secondary bag cover 3 is provided with several ventilation holes. The design of the ventilation holes can prevent the items in the removable inner bag 2 from becoming smelly due to prolonged lack of ventilation.
[0069] In some other embodiments, the secondary bag cover 3 is equipped with a vent valve that can be rotated to open and close. If there is concern that the items in the removable inner bag 2 may develop an odor due to prolonged lack of ventilation, the vent valve can be turned to open; if there is concern that the odor from the items in the removable inner bag 2 may leak out, the vent valve can be turned to close. Specifically, turning the vent valve to switch the airflow is prior art, as described in patent documents such as CN210114091U. The specific structure of the vent valve is not the focus of this embodiment and will not be elaborated upon.
[0070] It should be noted that storage bags with detachable inner pockets can be of various types, such as shoulder bag or hand bag. The following sections will introduce the two types of storage bags respectively.
[0071] (1) Shoulder bag or backpack (such as...) Figure 2 and Figure 3 (As shown)
[0072] When the main bag body 1 is a shoulder bag or a backpack, the main bag opening 102 is located at the top of the main bag body 1, and the secondary bag opening 101 is located at the bottom of the main bag body 1.
[0073] The bottom-mounted inner pocket design is suitable for storing heavier items such as shoes or damp clothes, making it ideal as a sports storage bag.
[0074] (2) Handbag (e.g.) Figure 1 (As shown)
[0075] When the main bag body 1 is a handbag, the main bag opening 102 is located at the top of the main bag body 1, and the secondary bag opening 101 is located on the side of the main bag body 1.
[0076] The side-mounted inner pocket design is suitable for storing lighter items such as ID cards, lipsticks, or mirrors, making it suitable as a casual bag or briefcase.
[0077] In summary, the removable inner bag storage bag provided in this embodiment has the following advantages:
[0078] ① Modular design enables categorized storage: The partitioned design of the main bag body 1 and the detachable inner bag 2 allows for the categorized storage of clean items and dirty / damp items, maintaining hygiene inside the bag.
[0079] ② Independent disassembly improves cleaning efficiency: The detachable inner pocket 2 can be disassembled separately through the inner zipper 4 and other connection methods, which makes it easy to quickly clean the dirty parts and avoids the whole bag from coming into contact with cleaning agents.
[0080] ③Double opening enhances convenience: The main pocket opening 102 and the secondary pocket opening 101 are separated, allowing you to access clean items without opening the secondary pocket, improving the convenience of daily use.
[0081] ④ Material optimization protects the lifespan of the bag: The inner waterproof layer (such as silicone) of the removable inner pocket 2 prevents stains from penetrating, and the outer material is the same as that of the main bag to reduce friction debris and reduce wear and tear on the main bag.
[0082] ⑤ Breathable design prevents odor accumulation: The secondary bag covers the ventilation holes 3 or the adjustable ventilation valve to balance ventilation and sealing needs, preventing damp items from becoming stuffy and smelly.
[0083] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
