Description

Technical Field

[0001] This utility model relates to the field of laundry detergent bottles, specifically a foldable and compressible portable laundry detergent bottle. Background Technology

[0002] Laundry detergent bottles, as everyday consumables, can be creatively repurposed for environmental protection. In terms of practicality, they can be cut into kitchen drain racks, watering cans, or storage boxes; the transparent bottles can be used to DIY flower pots, vases, or children's craft toys; and unopened or filled with water, they can also serve as simple fitness equipment or hand warmers. From a design perspective, products on the market emphasize the combination of function and aesthetics, such as patented designs like liquid level observation windows and non-slip bases, and are mostly made of recyclable PP / PE plastic.

[0003] Searching revealed that current laundry detergent bottles, in order to improve portability, are designed like the one described in announcement number CN219238000U, "A Hand Sanitizer Packaging Bottle Easy to Carry," with a bendable and compressible structure on the outer wall. However, in actual use, there is a problem: the bendable and compressible part is a soft structure, and traditional compression parts are difficult to provide stable support, resulting in unstable support. In view of this, the inventor urgently needs to design a stabilizing mechanism for the compression part of a laundry detergent bottle to improve its stability. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a foldable and compressible portable laundry detergent bottle to solve the technical problem of unstable support caused by the soft structure of the compression part of the laundry detergent bottle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable and compressible portable laundry detergent bottle, comprising a laundry detergent bottle body, wherein the laundry detergent bottle body includes an upper fixing ring, a middle fixing ring, and a lower fixing ring, wherein a folding part is connected between the upper fixing ring, the middle fixing ring, and the lower fixing ring, and an adjustment mechanism is provided on the outer side of the folding part, wherein the adjustment mechanism includes a support ring, wherein the inner side of the support ring is rotatably connected to the middle fixing ring through a snap-fit ​​ring, and the inner side of the support ring is threadedly connected to the upper fixing ring through internal threads and external threads.

[0006] By adopting the above technical solution, and by setting the upper fixing ring, middle fixing ring, lower fixing ring and flexible folding part in the main body of the laundry detergent bottle to cooperate with each other, the integrity of the bottle structure is ensured when compressed. At the same time, the support ring of the adjustment mechanism adopts a rigid transmission method with the internal thread meshing with the external thread of the upper fixing ring, combined with the rotational connection between the snap ring and the middle fixing ring, to form a two-way mechanical constraint.

[0007] Furthermore, the two sets of support rings are mirror images of each other, and the support rings are made of rigid plastic.

[0008] By adopting the above technical solution, the mirrored arrangement of the two sets of support rings forms a circumferential mechanical balance through the symmetrically distributed rigid support structure, effectively dispersing the lateral pressure generated by the sloshing of liquid inside the bottle and avoiding the risk of tipping over due to insufficient support at a single point.

[0009] Furthermore, the support ring can be rotated by an external user to adjust the folding compression amount of the corresponding folding part.

[0010] By adopting the above technical solution, the support ring can achieve stepless compression control by adjusting the rotation driven by the user and utilizing the self-locking characteristic of the threaded transmission. This makes the expansion and contraction process of the folding part smooth and can be precisely stopped at any position, solving the defect of uncontrollable compression of traditional elastic folding bottles.

[0011] Furthermore, a limiting ring is fixedly provided on the inner side of the support ring, and several protruding rings are provided on the outer sides of both the upper and lower fixing rings.

[0012] By adopting the above technical solution, the limiting ring on the inner side of the support ring and the convex ring on the outer side of the upper / lower fixing ring form a multi-level locking unit. Through the alternating engagement of the limiting ring and different convex rings, segmented mechanical fixing points are provided for the compression stroke of the folding part, completely eliminating the risk of springback in the folding state.

[0013] Furthermore, the convex rings are arranged linearly at equal intervals, and a limiting groove is formed between adjacent convex rings. The support ring is engaged with the upper or lower fixed ring through the limiting ring and any limiting groove.

[0014] By adopting the above technical solution, the convex rings arranged linearly at equal intervals and the limiting grooves formed between them are used to construct a standardized locking spacing, ensuring that the limiting ring can accurately fall into any gap when the support ring is displaced, and achieving a uniform locking force distribution throughout the entire stroke.

[0015] Furthermore, the corners of the limiting ring and the convex ring are chamfered to guide the sliding of the adapting limiting ring and its engagement with any limiting groove.

[0016] By adopting the above technical solution, the chamfered design of the limiting ring and the convex ring significantly reduces the frictional resistance during the sliding process of the snap ring, making the rotation operation of the support ring easier and smoother, and improving the human-computer interaction experience.

[0017] Furthermore, the upper side of the upper fixing ring is sealed by a sealing cap thread.

[0018] By adopting the above technical solution, the threaded sealing structure of the sealing cover and the upper fixing ring forces the sealing surface to fit tightly through spiral pressure, maintaining high gas-liquid sealing performance under folding, compression, or bumpy transportation conditions, thus eliminating the risk of leakage.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention utilizes a rotating support ring, whose internal thread engages with the external thread of the upper fixed ring to generate axial displacement, simultaneously pushing the middle fixed ring to move. This precisely controls the compression of the folded portion, achieving stepless adjustment of the folded volume and solving the problem of uncontrollable compression in traditional folding bottles. The limiting ring on the inner side of the support ring is guided by the chamfered surface and automatically slides into the limiting groove formed by the convex ring on the surface of the upper or lower fixed ring, forming a mechanical rigid lock to prevent springback or displacement in the folded state and ensure the stability of the bottle after compression.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1: A foldable and compressible portable laundry detergent bottle, such as... Figure 1-6As shown, the device includes a laundry detergent bottle body 1, which comprises an upper fixing ring 101, a middle fixing ring 103, and a lower fixing ring 104. A folding portion 102 connects the upper fixing ring 101, the middle fixing ring 103, and the lower fixing ring 104. An adjustment mechanism 2 is provided on the outer side of the folding portion 102. The adjustment mechanism 2 includes a support ring 201. The inner side of the support ring 201 is rotatably connected to the middle fixing ring 103 via a snap-fit ​​ring 202. The inner side of the support ring 201 is threadedly connected to the upper fixing ring 101 via an internal thread 203 and an external thread 204. The device is designed to accommodate laundry detergent bottles. The upper fixing ring 101, middle fixing ring 103, and lower fixing ring 104 in the liquid bottle body 1, along with the flexible folding part 102, ensure the structural integrity of the bottle body during compression. Meanwhile, the support ring 201 of the adjustment mechanism 2 adopts a rigid transmission method with the internal thread 203 meshing with the external thread 204 of the upper fixing ring 101. Combined with the rotational connection between the snap ring 202 and the middle fixing ring 103, a two-way mechanical constraint is formed. This not only precisely controls the compression stroke of the folding part 102 but also resists deformation and displacement caused by external force, significantly improving the structural stability in the folded state.

[0030] See Figure 1 , Figure 4 The two sets of support rings 201 are mirror-arranged and made of rigid plastic. The mirror-arrangement of the two sets of support rings 201 forms a circumferential mechanical balance through the symmetrical distribution of rigid support structure, which effectively disperses the lateral pressure generated by the sloshing of liquid inside the bottle and avoids the risk of tipping over due to insufficient support at a single point. At the same time, the use of rigid plastic material gives the support rings 201 high bending stiffness, making them less prone to deformation or slippage during rotation and adjustment, ensuring the reliability and service life of the threaded drive. It also forms a rigid-flexible composite structure with the flexible folding part 102, taking into account both portability and durability.

[0031] See Figure 1 , Figure 2 , Figure 4 , Figure 5 The support ring 201 is driven to rotate by an external user, which adjusts the folding compression amount of the corresponding folding part 102. The support ring 201 is adjusted by user-driven rotation, and the self-locking characteristic of the threaded transmission is used to achieve stepless compression control. This makes the extension and retraction process of the folding part 102 smooth and can be precisely stopped at any position. This solves the defect of uncontrollable compression amount of traditional elastic folding bottles. At the same time, only a single-step rotation operation is needed to complete the folding compression and locking functions simultaneously, which greatly simplifies the user operation process. It is especially suitable for the needs of quick storage in travel, outdoor and other scenarios, and improves the convenience of use.

[0032] Example 2: See Figure 4 , Figure 5 , Figure 6A limiting ring 205 is fixedly provided on the inner side of the support ring 201. Several protruding rings 206 are provided on the outer sides of the upper fixing ring 101 and the lower fixing ring 104. The limiting ring 205 on the inner side of the support ring 201 and the protruding rings 206 on the outer sides of the upper fixing ring 101 / lower fixing ring 104 form a multi-level locking unit. By the alternating engagement of the limiting ring 205 with different protruding rings 206, segmented mechanical fixing points are provided for the compression stroke of the folding part 102, completely eliminating the risk of springback in the folding state. At the same time, the dense arrangement of the protruding rings 206 increases the number of effective locking positions, making the folding height adjustment more precise and meeting the storage needs of different volumes.

[0033] See Figure 4 , Figure 5 , Figure 6 A number of convex rings 206 are arranged linearly at equal intervals, and a limiting groove 207 is formed between adjacent convex rings 206. The support ring 201 is engaged with the upper fixed ring 101 or the lower fixed ring 104 through the limiting ring 205 and any limiting groove 207. The convex rings 206 arranged linearly at equal intervals and the limiting grooves 207 formed between them construct a standardized engagement spacing to ensure that the limiting ring 205 can accurately fall into any gap when the support ring 201 is displaced, thereby achieving a uniform locking force distribution throughout the entire stroke. At the same time, the engagement mechanism of the limiting ring 205 and the limiting groove 207 forms a rigid interlocking structure, which offsets the rebound stress of the folded part 102 through mechanical interlocking, avoiding locking failure caused by liquid gravity or external vibration.

[0034] See Figure 4 , Figure 5 , Figure 6 The corners of the limiting ring 205 and the convex ring 206 are chamfered to guide the sliding of the limiting ring 205 and its engagement with any limiting groove 207. The chamfered design of the limiting ring 205 and the convex ring 206 greatly reduces the frictional resistance during the sliding process of the engaging ring 202, making the rotation of the support ring 201 easier and smoother, and improving the human-machine interaction experience. At the same time, the chamfered surface guides the limiting ring 205 to slide into the limiting groove 207 along a preset trajectory, preventing skew, jamming or misalignment, and ensuring the accuracy and stability of each locking action.

[0035] See Figure 1 , Figure 2 , Figure 4 , Figure 5 The upper side of the upper fixing ring 101 is sealed by the threaded sealing cap 3. The threaded sealing structure of the sealing cap 3 and the upper fixing ring 101 forces the sealing surface to fit tightly through spiral pressure, maintaining high gas-liquid sealing performance under folding compression or transportation bumps, eliminating the risk of leakage. At the same time, it operates independently of the folding adjustment mechanism, ensuring that the bottle mouth seal is not affected by the folding operation. The threaded connection facilitates repeated disassembly and cleaning, extending the bottle's reuse cycle and meeting environmental protection requirements.

[0036] The implementation principle of this embodiment is as follows: the portable laundry detergent bottle rotates the support ring 201, and uses its internal thread 203 to mesh with the external thread 204 of the upper fixed ring 101 to drive axial displacement, and simultaneously pushes the support ring 201 to move the middle fixed ring 103 through the snap ring 202, forcing the flexible folding part 102 to compress or extend between the upper fixed ring 101 and the lower fixed ring 104.

[0037] Another embodiment: During the displacement of the support ring 201, the limiting ring 205 on the inner side of the support ring 201 is guided by the chamfer of the inclined surface and slides into the limiting groove 207 formed by the equidistant convex rings 206 on the surfaces of the upper fixed ring 101 and the lower fixed ring 104 to achieve mechanical locking. This provides another implementation method for this application. The compression amount of the folding part 102 is adjusted, and the sealing cap 3 connected by the thread ensures the sealing of the bottle mouth. Thus, the folding amount is stably adjusted by the deformation driven by the thread rotation and the rigid locking of the limiting groove.
