Description
Technical Field
[0001] This application relates to the technical field of packaging, and in particular, to an adjustable load-bearing wet-dry separation tote bag. Background Art
[0002] A tote bag generally refers to a bag-shaped object with a handle or a carrying beam, and its materials include paper, plastic, non-woven fabric, canvas, Oxford cloth, etc. The core function of a tote bag is to facilitate the carrying of items. At the same time, with the development of design, it has gradually become a daily necessity or a commercial promotion carrier that combines practicality and fashion.
[0003] With the increasing demand of consumers for multi-functional portable products, the design of tote bags has gradually developed from single storage to refined zoning. Especially in daily life scenarios (such as shopping, fitness, traveling, etc.), users often need to carry dry items (such as clothes, electronic devices) and wet items (such as rain gear, refrigerated food, clothes for changing after exercise) at the same time, so that the diversity of items placed in the tote bag is limited. Summary of the Invention
[0004] In order to increase the diversity of items placed in the tote bag, the purpose of this application is to provide an adjustable load-bearing wet-dry separation tote bag.
[0005] An adjustable load-bearing wet-dry separation tote bag provided by this application adopts the following technical solution: An adjustable load-bearing wet-dry separation tote bag includes an outer bag and an inner card that can be detachably placed inside the outer bag. The outer bag has a placement space. The inner card includes an upright portion, a movable portion, and a placement portion arranged in sequence along the length direction. The placement portion is placed on the bottom surface of the placement space, the upright portion stands upright in the placement space, the movable portion is in contact with or separated from the bottom surface of the placement space, the upright portion is in contact with or separated from the inner wall of the placement space, and the tote bag has a single-compartment state and a multi-compartment state; When in the single-compartment state, both the placement portion and the movable portion are in contact with the bottom surface of the placement space, and the upright portion is in contact with the inner wall of the placement space; When in the multi-compartment state, the placement portion is in contact with the bottom surface of the placement space, the movable portion is separated from the bottom surface of the placement space, the upright portion is separated from the inner wall of the placement space, and the movable portion and the upright portion cooperate to partition the placement space.
[0006] By adopting the above technical solution, the moving part and the upright part cooperate to divide the placement space into a first compartment and a second compartment. The first compartment can be used to place dry or wet items, and the second compartment can also place dry or wet items. The dryness and wetness of the items placed in the first compartment and the second compartment can be the same or different. The settings of the first compartment and the second compartment can accommodate items with the same or different dryness and wetness. Especially when the dryness and wetness are different, the carrying bag can achieve dry-wet separation through the cooperation of the upright part and the moving part, reducing the cross-contamination of dry and wet items, so that the present application can effectively improve the diversity of placed items.
[0007] Optionally, the outer bag has a main handle, and an auxiliary handle is provided at one end of the upright part away from the moving part. When the carrying bag is in the multi-compartment state, the main handle and the auxiliary handle are used simultaneously.
[0008] By adopting the above technical solution, when the carrying bag is in the multi-compartment state, the items are placed in the placement part to exert pressure on the placement part. At this time, when lifting the carrying bag, the main handle and the auxiliary handle cooperate to achieve three-rope load-bearing, thereby reducing the stress at the knot of the carrying bag rope. Through laboratory comparative tests, when loading 15 kg of items, the stress concentration at the knot of the traditional carrying bag rope reaches 38 MPa, and the design solution of the present application can be reduced to 12 MPa.
[0009] Optionally, the auxiliary handle is provided with a supporting rope, and the end of the supporting rope extends to the placement part.
[0010] By adopting the above technical solution, when the items are placed in the placement part, they will simultaneously press down on the supporting rope. The main handle and the auxiliary handle at the top cooperate with the supporting rope at the bottom to form a rope distribution in a triangular shape, making the mechanical structure more stable.
[0011] Optionally, a hook blocking part is provided at one end of the placement part away from the moving part.
[0012] By adopting the above technical solution, after the items are placed in the placement part, when a pulling force is applied to the handle, the hook blocking part is blocked by the items to limit the separation between the placement part and the items, thereby further improving the stability of the auxiliary handle when dispersing the force.
[0013] Optionally, when the carrying bag is in the multi-compartment state, the area where the placement part is located is a wet compartment.
[0014] By adopting the above technical solution, the setting of the placement part increases the thickness of the bottom of the carrying bag, thereby improving the moisture resistance of the carrying bag, enabling the carrying bag to accommodate more wet items, and further improving the diversity of items placed in the handbag.
[0015] Optionally, a water-proof sealing pad is detachably provided on the bottom surface of the placement space, and the placement part is placed on the water-proof sealing pad.
[0016] By adopting the above technical solution, the water-blocking and sealing gasket is made of silica gel or rubber to have certain elasticity. The heavier the weight of the item placed on the placement part, the better the pressing and sealing effect between the placement part and the water-blocking and sealing gasket, thereby further improving the dry-wet separation effect and reducing the occurrence of cross-contamination of items.
[0017] Optionally, the edge of the water-blocking and sealing gasket has a clamping platform, and the end of the placement part away from the moving part is detachably connected to the clamping platform.
[0018] By adopting the above technical solution, during the installation of the inner clamp, the end of the placement part is clamped into the clamping platform to improve the connection stability of the placement part. Optionally, at least one of the placement part, the moving part, and the upright part has a water-absorbing layer, and the water-absorbing layer is located on the side of the inner clamp facing the wet compartment.
[0019] By adopting the above technical solution, when a wet item is placed in the wet compartment, the water vapor or a small amount of water generated by the wet item can be adsorbed by the water-absorbing layer, thereby further reducing the occurrence of water contaminating the other compartment.
[0020] Optionally, a water-blocking platform is arranged around the edge of the placement part.
[0021] By adopting the above technical solution, when the water content of the wet item is relatively large, the seeping water is blocked by the water-blocking platform within the range of the placement part, minimizing the situation where water seeps through the bottom of the placement part into the other compartment.
[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. The moving part and the upright part cooperate to divide the placement space into a first compartment and a second compartment. The first compartment can be used to place dry items or wet items, and the second compartment can also place dry items or wet items. The dryness and wetness of the items placed in the first compartment and the second compartment can be the same or different. The setting of the first compartment and the second compartment can be used for placing items with the same or different dryness and wetness. Especially when the dryness and wetness are different, the carrying bag can achieve dry-wet separation through the cooperation of the upright part and the moving part, reducing the dry-wet cross-contamination of items, so that the present application can effectively improve the diversity of placed items. 2. When the carrying bag is in a multi-compartment state, the item is placed on the placement part to exert pressure on the placement part. At this time, when lifting the carrying bag, the main lifting handle and the auxiliary lifting handle cooperate to achieve three-rope load-bearing, thereby reducing the stress at the knot of the carrying bag rope; when the item is placed on the placement part, it will simultaneously press down the supporting rope. The main lifting handle and the auxiliary lifting handle at the top cooperate with the supporting rope at the bottom to form a rope distribution in a triangular shape, making the mechanical structure more stable. 3. The area where the placement part is located is a wet compartment. The setting of the placement part increases the thickness of the bottom of the carrying bag, thereby improving the moisture resistance of the carrying bag, enabling the carrying bag to hold more wet items, and further enhancing the diversity of items that can be placed in the handbag.

[0025] Detailed Embodiment S The following is a further detailed description of the present application in conjunction with the attached Figures 1-6 , drawings.
[0026] Embodiment 1 of the present application discloses an adjustable load-bearing dry-wet separation carrying bag. The carrying bag has a placement space for placing items. The placement space is divided into a first compartment and a second compartment. The first compartment can be used to place dry items or wet items, and the second compartment can also place dry items or wet items. The dryness and wetness of the items placed in the first compartment and the second compartment can be the same or different. Any dry or wet items placed in the first compartment or the second compartment are within the protection scope of the present application. For the convenience of functional description, in the following description: the first compartment is a wet compartment, that is, for placing wet items; the second compartment is a dry compartment, that is, for placing dry items.
[0027] Embodiment 1: Referring to Figure 1 and Figure 2 , an adjustable load-bearing dry-wet separation carrying bag includes an outer bag 1 and an inner card 2 that can be detachably placed inside the outer bag 1. The material of the outer bag 1 can be a waterproof material such as plastic, and the inner card 2 can be made of hard plastic or the like.
[0028] The outer bag 1 has a placement space 11 in the shape of a quasi - tetrahedron, with a length direction, a width direction, and a height direction. The outer bag 1 has a main handle 12 on each of the two faces in the width direction.
[0029] Before the inner card 2 is installed into the placement space 11 of the outer bag 1, it is a plate - like structure in the shape of a quasi - rectangle, and the width of the inner card 2 is the same as the width of the placement space 11. The inner card 2 has three folding seams running through its width direction. The three folding seams are distributed along the length direction of the inner card 2 so that the inner card 2 includes an upright portion 21, a moving portion 22, and a placement portion 23 arranged in sequence along the length direction. The sum of the length of the upright portion 21 and the width of the moving portion 22 is equal to the height of the placement space 11, and the sum of the width of the moving portion 22 and the width of the placement portion 23 is equal to the width of the placement space 11. By changing the width of the moving portion 22 and the width of the placement portion 23, the sizes of the two compartments in the placement space 11 can be changed, or the sizes of the two compartments in the placement space 11 can also be changed by changing the position of the placement portion 23 on the bottom surface of the placement space 11. In the first embodiment, the width of the moving portion 22 is equal to the width of the placement portion 23, so that the inner card 2 can divide the placement space 11 into two spaces of approximately the same size. For the convenience of use, an auxiliary handle 24 is provided at one end of the upright portion 21 away from the moving portion 22, and the auxiliary handle 24 is used in conjunction with the main handle 12. Optionally, the auxiliary handle 24 is provided with a supporting rope, and the end of the supporting rope extends to the placement portion 23.
[0030] Refer to Figure 2 and Figure 3 When the inner card 2 is not installed into the placement space 11 of the outer bag 1, the placement portion 23 is placed on and attached to the bottom surface of the placement space 11, the moving portion 22 is attached to or detached from the bottom surface of the placement space 11 according to actual needs, the upright portion 21 stands upright in the placement space 11, and the upright portion 21 is attached to or detached from the inner wall of the placement space 11 according to actual needs.
[0031] According to whether the upright portion 21 is attached to the inner wall of the placement space 11 or not, the use states of the carrying bag can be defined as a single - compartment state and a multi - compartment state.
[0032] Refer to Figure 1 and Figure 2 In the single - compartment state, it is used for mixed storage of objects. At this time, both the placement portion 23 and the moving portion 22 are attached to the bottom surface of the placement space 11, and the upright portion 21 is attached to the inner wall of the placement space 11. Therefore, there is only one integral placement space 11 in the outer bag 1. At this time, the auxiliary handle 24 naturally falls and is stored in the outer bag 1. In particular, it can hang on the side where the inner card 2 is attached to the inner wall, reducing the interference during the placement of items. The carrying bag in the single - compartment state can be regarded as an ordinary handbag for use.
[0033] Refer to Figure 3 andFigure 4 In the multi-compartment state, it is used to place dry items and wet items separately to achieve dry-wet separation and reduce the cross-contamination between dry and wet items. At this time, the placement part 23 fits against the bottom surface of the placement space 11, the moving part 22 disengages from the bottom surface of the placement space 11, and the upright part 21 disengages from the inner wall of the placement space 11. The moving part 22 and the upright part 21 cooperate to partition the placement space 11, and the moving part 22 and the upright part 21 cooperate to divide the placement space 11 into a wet compartment and a dry compartment. Among them, the area where the placement part 23 is located is the wet compartment. The setting of the placement part 23 increases the thickness of the bottom of the carrying bag, thereby improving the moisture resistance of the carrying bag. At this time, the auxiliary handle 24 is pulled out, and the main handle 12 and the auxiliary handle 24 are used simultaneously to achieve three-rope load-bearing, thereby reducing the stress at the knot of the carrying bag rope.
[0034] The implementation principle of the first embodiment of this application is as follows: (1) When using the carrying bag as an ordinary handbag, adjust the position of the inner card 2 so that the carrying bag is in the single-compartment state. All items are placed in the placement space 11 and pressed on the placement part 23 and the moving part 22 of the inner card 2. The placement part 23 and the moving part 22 cooperate together to thicken the bottom of the outer bag 1. If there are wet items, they can be placed in the direction close to the upright part 21 to improve the firmness of the carrying bag; (2) When using the carrying bag as a dry-wet separation carrying bag, adjust the position of the inner card 2 so that the carrying bag is in the multi-compartment state. Divide the items to be placed into dry items and wet items. The dry items are placed in the dry compartment, and the wet items are placed in the wet compartment and pressed on the placement part 23. The placement part 23 thickens the bottom of the outer bag 1 to make the area where the wet items are placed more firm. Placing the dry items and the wet items in different compartments can achieve dry-wet separation and reduce the cross-contamination between dry and wet items, thereby effectively improving the diversity of the placed items.
[0035] Embodiment Two: Referring to Figure 5 and Figure 6 In this Embodiment Two, the difference from Embodiment One is that a water-proof sealing gasket 3 is added between the bottom surface of the placement space 11 and the placement part 23. The water-proof sealing gasket 3 is used to enhance the sealing performance between the wet compartment and the dry compartment and optimize the dry-wet separation effect.
[0036] Specifically, the water-proof sealing gasket 3 is made of silicone or rubber to have a certain elasticity. The water-proof sealing gasket 3 is placed on the bottom surface of the placement space 11, and the placement part 23 is placed on the water-proof sealing gasket 3. The heavier the weight of the item placed on the placement part 23, the greater the deformation of the water-proof sealing gasket 3 under pressure, and the better the pressing and sealing effect between the placement part 23 and the water-proof sealing gasket 3.
[0037] In order to improve the installation stability of the placement part 23, the edge of the water-proof gasket 3 has an upwardly protruding clamping platform 31, and the end of the placement part 23 away from the moving part 22 can be embedded into the clamping platform 31 to achieve a detachable connection with the clamping platform 31.
[0038] In order to further improve the water-proof and sealing effect, the structure of the inner clamp 2 can be selectively optimized.
[0039] In the case where the water content or water production of the wet item is relatively small, additionally and optionally, at least one of the placement part 23, the moving part 22, and the upright part 21 has a water-absorbing layer, and the water-absorbing layer can be formed by fixing or pasting water-absorbing fabrics such as flannelette. The water-absorbing layer is located on the side of the inner clamp 2 facing the wet compartment. When a wet item is placed in the wet compartment, the water vapor or a small amount of water generated by the wet item can be adsorbed by the water-absorbing layer, thereby further reducing the occurrence of water contamination in the other compartment.
[0040] In the case where the water content or water production of the wet item is relatively large, additionally and optionally, a hook and block part 25 is provided at one end of the placement part 23 away from the moving part 22, and a water-blocking platform 231 is provided around the edge of the placement part 23. The hook and block part 25 and the water-blocking platform 231 enclose a small water storage area, and the water seeping out of the wet item is blocked by the water-blocking platform 231 within the range of the placement part 23, minimizing the occurrence of water seeping through the bottom of the placement part 23 into the other compartment as much as possible. The hook and block part 25 protrudes slightly upward from the water-blocking platform 231. When a pulling force is applied to the handle after the item is placed on the placement part 23, the hook and block part 25 is blocked by the item to limit the separation between the placement part 23 and the item, thereby further improving the stability of the auxiliary handle 24 when the force is dispersed.

The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.
