Description

Technical Field

[0001] This invention relates to the field of bottle technology, and in particular to a dispensing cap for fragrance beads and a storage bottle for fragrance beads. Background Technology

[0002] In daily life, fragrance beads are a commonly used clothing care product, and the ease of use and hygiene of their storage bottles are of great concern. Traditional fragrance bead storage bottles mostly use a regular cap design. To dispensing, the cap must be completely unscrewed, and the fragrance beads inside the bottle must be poured directly into the washing machine, or the cap can be used as an intermediary to pour the fragrance beads into the cap before pouring them into the washing machine. Both of these methods make it difficult to accurately control the amount used. Using too much or too little will affect the fragrance retention effect on the clothes, and the beads are also very easy to scatter outside the washing machine. In addition, during the opening and closing process or if the cap is not fully tightened, external humid air may enter, causing the fragrance beads to become damp and clump together. Clumped fragrance beads may get stuck at the bottle opening or fall out in one piece during use, seriously affecting the user experience.

[0003] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a dispensing cap and a fragrance bead storage bottle for fragrance beads, aiming to solve the problem that existing fragrance bead storage bottles cannot accurately control the amount of fragrance beads used.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dispensing cap for fragrance beads includes an inner cap, an outer cap, a separating component, and a dispensing cylinder. Both the inner cap and the outer cap are hollow shells with open bottoms. The top of the inner side of the outer cap is provided with a receiving cylinder, and the bottom of the receiving cylinder is provided with a linkage mechanism. The inner cap is rotatably disposed inside the outer cap and is connected to the receiving cylinder through the linkage mechanism. The top of the inner cap is provided with a first through hole, and the separating component is connected to the inner wall of the receiving cylinder. The top of the outer cap is provided with a second through hole, and the dispensing cylinder is slidably engaged with the second through hole, with its bottom end communicating with the separating component.

The guiding mechanism is located inside the inner cap and is detachably connected to the other end of the guide roller. The top of the guiding mechanism abuts against the inner side of the inner cap.

[0008] As described above, the dispensing cap for fragrance beads includes a guiding mechanism comprising a disc, a sealing cap, a snap-fit ​​ring, multiple guiding arms, and multiple arc-shaped plates. The multiple arc-shaped plates are sequentially arranged around the central axis of the inner cap on the inner side of the inner cap. The snap-fit ​​ring is sleeved on the outer periphery of the second extrusion protrusion. The disc is spaced apart on the side of the snap-fit ​​ring facing away from the storage bin. The other end of the guiding roller passes through the snap-fit ​​ring and connects to the disc. The multiple guiding arms are sequentially arranged around the central axis of the inner cap. Each guiding arm's two ends are connected to the disc and the snap-fit ​​ring, respectively. Each guiding arm includes an arc-shaped arm, an inclined plate, and a flexible scraper. The inclined plate extends inwardly along the inner edge of the arc-shaped arm. The flexible scraper is located on the outer periphery of the arc-shaped arm. The disc has a protruding ring on the side facing away from the snap-fit ​​ring. The sealing cap is an inverted cone with an annular groove at its top that engages with the protruding ring.

[0009] As described above, the dispensing cap for fragrance beads has an hourglass-shaped guide roller with multiple guide grooves on its outer periphery. The guide roller includes a first roller, a second roller, a limiting block, and a limiting groove. The first roller and the second roller are coaxially arranged. The end of the first roller away from the second roller is connected to the partition. The limiting groove is located at the end of the first roller near the second roller. The limiting block is located at the end of the second roller near the first roller and engages with the limiting groove. The first roller, the second roller, and the disc are respectively provided with screw holes.

[0010] As described above, the dispensing cap for fragrance beads has an annular first and second extrusion protrusion. The first extrusion protrusion includes a first protrusion and a first recess arranged coaxially from the inside to the outside, and the second extrusion protrusion includes a second recess and a second protrusion arranged coaxially from the inside to the outside.

[0011] As described above, the dispensing cap for fragrance beads includes a storage hopper, a guide cylinder, and multiple first connecting ports. The storage hopper is a hollow shell with an open bottom, and the diameter of its inner wall gradually narrows towards the side away from the partition. The guide cylinder is disposed through the middle of the storage hopper. Multiple first connecting ports are sequentially arranged around the periphery of the guide cylinder and are all connected to the interior of the storage hopper. The dispensing cylinder includes a cylinder body, a limiting mechanism, and multiple second connecting ports. The cylinder body passes through the outer cap and slides with the guide cylinder. The limiting mechanism connects the cylinder body and the guide cylinder. Multiple second connecting ports are sequentially arranged around the periphery of the cylinder body and are respectively connected to multiple first connecting ports one by one.

[0012] As described above, the dispensing cap for fragrance beads includes a limiting mechanism comprising two sliding grooves, two sliding blocks, and a limiting plate. The two sliding grooves are respectively located at the bottom of the outer periphery of the cylinder, and the two sliding blocks are respectively located on both sides of the inner wall of the guide cylinder. The two sliding grooves and the two sliding blocks correspond one-to-one and slide in cooperation. The limiting plate is connected to the bottom of the cylinder by screws.

[0013] As described above, the dispensing cap for fragrance beads has a first flange on the outer periphery of the bottom of the inner cap, and a movable groove and a second flange are provided sequentially from top to bottom on the inner periphery of the bottom of the outer cap. The first flange engages with the movable groove. The linkage mechanism includes multiple locking grooves and multiple locking protrusions. The multiple locking grooves surround the bottom edge of the abutment cylinder, and the multiple locking protrusions surround the top of the inner cap, and each corresponds to and engages with one of the multiple locking grooves.

[0014] The present invention also provides a fragrance bead storage bottle, including a bottle body and a dispensing cap as described above. The bottle body has an external thread at the bottle opening, and the inner circumference of the inner cap has an internal thread, wherein the internal thread and the external thread are threadedly engaged.

[0015] Beneficial effects:

[0016] This invention discloses a dispensing cap for fragrance beads, comprising an inner cap, an outer cap, a separating assembly, and a dispensing cylinder. Both the inner and outer caps are hollow shells with open bottoms. The top of the inner side of the outer cap has a receiving cylinder, and the bottom of the receiving cylinder has a linkage mechanism. The top of the inner cap has a first through hole, and the top of the outer cap has a second through hole. The inner and outer caps are rotatable relative to each other. When the dispensing cap needs to be combined with or separated from the bottle body, the linkage mechanism causes the inner and outer caps to rotate synchronously. When fragrance beads need to be dispensed, the dispensing cap is in an inverted state, and rotating the outer cap causes relative rotation between it and the inner cap. The separating assembly... The component transfers the fragrance beads inside the bottle to the dispensing cylinder. By setting the size of the dispensing cylinder, a quantitative amount of fragrance beads can be dispensed. Simultaneously, the separation component can break up any clumps of fragrance beads back into individual beads, facilitating control over the amount dispensed. The dispensing cap disclosed in this application uses a linkage mechanism to link or delink the inner and outer caps, separating the dispensing operation from the cap assembly / disassembly operation, thus achieving both structural compactness and multifunctionality. Furthermore, the separation component breaks up the clumps of fragrance beads back into individual beads before they enter the dispensing cylinder, ensuring smooth flow of the fragrance beads while allowing for more precise control over the amount dispensed.

Detailed Implementation

[0022] This invention provides a dispensing cap for fragrance beads and a storage bottle for fragrance beads. To make the purpose, technical solution and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In the description of this invention, it should be understood that the terms "top" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and should not be construed as limiting the invention; in addition, the terms "installation," "connection," etc. should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] like Figure 1-4 As shown in the figure, this application proposes a dispensing bottle cap for fragrance beads, including an inner cap 1, an outer cap 2, a separating component 3, and a dispensing cylinder 4. The inner cap 1 and the outer cap 2 are both hollow shells with bottom openings. The top of the inner side of the outer cap 2 is provided with an abutment cylinder 21, and the bottom of the abutment cylinder 21 is provided with a linkage mechanism. The inner cap 1 is rotatably disposed inside the outer cap 2 and is connected to the abutment cylinder 21 through the linkage mechanism. The top of the inner cap 1 is provided with a first through hole 11. The separating component 3 is connected to the inner wall of the abutment cylinder 21. The top of the outer cap 2 is provided with a second through hole 22. The dispensing cylinder 4 is slidably engaged with the second through hole 22, and its bottom end is connected to the separating component 3. The end of the separating component 3 away from the dispensing cylinder 4 passes through the first through hole 11.

[0025] This invention discloses a dispensing cap for fragrance beads, comprising an inner cap 1, an outer cap 2, a separating component 3, and a dispensing cylinder 4. Both the inner cap 1 and the outer cap 2 are hollow shells with openings at the bottom. The top of the inner side of the outer cap 2 is provided with an abutment cylinder 21, and the bottom of the abutment cylinder 21 is provided with a linkage mechanism. The top of the inner cap 1 has a first through hole 11, and the top of the outer cap 2 has a second through hole 22. The inner cap 1 and the outer cap 2 are rotatable relative to each other. When it is necessary to combine or separate the dispensing cap from the bottle body, the linkage mechanism causes the inner cap 1 and the outer cap 2 to rotate synchronously. When it is necessary to dispense fragrance beads, the dispensing cap is in an inverted state, and rotating the outer cap 2 causes relative rotation between it and the inner cap 1. The separation component 3 transfers the fragrance beads from the bottle to the dispensing cylinder 4. By setting the size of the dispensing cylinder 4, a quantitative amount of fragrance beads can be dispensed. Simultaneously, the separation component 3 can break up any clumps of fragrance beads back into individual beads, facilitating control over the amount dispensed. The dispensing cap for fragrance beads disclosed in this application uses a linkage mechanism to link or delink the inner cap 1 and the outer cap 2, separating the dispensing operation from the cap assembly / disassembly operation, thus achieving both structural compactness and multifunctionality. Furthermore, the separation component 3 breaks up the clumps of fragrance beads back into individual beads before they enter the dispensing cylinder 4, ensuring smooth flow of the fragrance beads while allowing for more precise control over the amount dispensed.

[0026] The inner side of the abutting cylinder 21 is provided with an abutting ring. The separating component 3 includes a storage bin 31, a partition 32, a guide roller 33, and a guiding mechanism 34. The storage bin 31 is disposed inside the abutting cylinder 21 and is engaged with the abutting ring. The partition 32 covers the bottom of the storage bin 31 and is provided with multiple communicating grooves 35. The picking cylinder 4 passes sequentially through the second through hole 22 and the top of the storage bin 31 and communicates with the inner side of the storage bin 31. One end of the guide roller 33 is connected to the side of the partition 32 facing away from the storage bin 31. The other end of the guide roller 33 passes through the first through hole 11. The upper and lower sides of the top surface of the inner cover 1 are respectively provided with a first extrusion protrusion 12 and a second extrusion protrusion 13. The guide roller 33 forms an interconnected extrusion channel 5 with the first extrusion protrusion 12, the first through hole 11, and the second extrusion protrusion 13. The guide mechanism 34 is disposed inside the inner cover 1 and is detachably connected to the other end of the guide roller 33. The top of the guide mechanism 34 abuts against the inner side of the inner cover 1. The storage bin 31 and the partition... 32 and the abutment ring are respectively provided with screw holes for screws to pass through and fix. When the outer cover 2 and the inner cover 1 rotate relative to each other, the guide roller 33 and the guide mechanism 34 follow the outer cover 2 to rotate relative to the inner cover 1. The guide mechanism 34 and the second extrusion protrusion 13 cooperate to guide the fragrance beads into the guide mechanism 34. During continuous rotation, more single fragrance beads and clumps enter the guide mechanism 34 and are squeezed against each other. Larger clumps of fragrance beads are squeezed and broken into smaller clumps or single beads. The granules enter the extrusion channel 5, the size of which is between the size of a single fragrance bead and the size of two fragrance beads. The guide roller 33 moves the fragrance beads and cooperates with the first extrusion protrusion 12 to extrude the fragrance bead cluster, dispersing it back into single fragrance beads. The dispersed single fragrance beads enter the storage bin 31 through multiple connecting grooves 35 for temporary storage. The dispensing cylinder 4 can dispense a fixed amount of fragrance beads from the storage bin 31 at a time. At the same time, the abutment ring provides a limiting and connection base for the partition 32 of the storage bin 31.

[0027] In this embodiment of the application, the size of a single fragrance bead is 3-8mm, and the size of the connecting groove 35 is between the size of a single fragrance bead and the size of two beads, preferably 5-10mm, that is, the size of the connecting groove 35 is 2mm larger than the size of a single fragrance bead.

[0028] The material guiding mechanism 34 includes a disc 341, a sealing cap 342, a snap-fit ​​ring 343, multiple guide arms 344, and multiple arc-shaped plates 345. The multiple arc-shaped plates 345 are sequentially arranged around the central axis of the inner cover 1 on the inner side of the inner cover 1. The snap-fit ​​ring 343 is sleeved on the outer periphery of the second extrusion protrusion 13. The disc 341 is spaced apart on the side of the snap-fit ​​ring 343 facing away from the storage bin 31. The other end of the guide roller 33 passes through the snap-fit ​​ring 343 and connects to the disc 341. The multiple guide arms 344 sequentially surround the inner cover 1. The central axis is set, and each guide arm 344 is connected at both ends to the disk 341 and the snap ring 343, respectively. The guide arm 344 includes an arc-shaped arm 346, an inclined plate 347, and a flexible scraper 348. The inclined plate 347 extends inwardly along the inner edge of the arc-shaped arm 346, and the flexible scraper 348 is located on the outer periphery of the arc-shaped arm 346. The disk 341 has a protruding ring 349 on the side opposite to the snap ring 343. The sealing cap 342 is an inverted cone, and its top is provided with a snap-fit ​​mechanism to engage with the protruding ring 349. The annular groove 340 allows the outer cover 2 and the inner cover 1 to rotate relative to each other. Due to the interconnection between the abutment ring, the storage bin 31, the partition 32, the guide roller 33, and the guide mechanism 34, the guide mechanism 34 rotates with the outer cover 2. The snap-fit ​​ring 343 presses against the inner wall of the inner cover 1. The second extrusion protrusion 13 provides guidance and limitation for the snap-fit ​​ring 343. Fragrance beads fall into multiple arc-shaped plates 345, and multiple guide arms 344 rotate to actuate the fragrance beads. Arc-shaped arms 346 provide a supporting base. The inclined plate 347 guides the fragrance beads inside into the extrusion channel 5. The flexible scraper 348 is made of silicone. The flexible scraper 348 scrapes and deforms against the inner side of the arc plate 345. Due to the guidance of the arc plate 345, the fragrance beads on the flexible scraper 348 are squeezed and flow towards the center against the surface of the guide arm 344. When the fragrance beads in the center of the guide mechanism 34 flow away, the fragrance beads above the sealing cap 342 adhere to its conical surface and disperse outward and flow towards the center of the guide mechanism 34, ensuring smooth flow of the fragrance beads.

[0029] The guide roller 33 is hourglass-shaped and has multiple guide grooves on its outer periphery. The guide roller 33 includes a first roller 331, a second roller 332, a limiting block 333, and a limiting groove 334. The first roller 331 and the second roller 332 are coaxially arranged. The end of the first roller 331 away from the second roller 332 is connected to the partition plate 32. The limiting groove 334 is located at the end of the first roller 331 near the second roller 332. The limiting block 333 is located at the end of the second roller 332 near the first roller 331 and engages with the limiting groove 334. The first roller 331, the second roller 332, and the disc 341 are respectively... Correspondingly, screw holes are provided, and the guide roller 33 is set in an hourglass shape, forming a large cavity at its feed end to facilitate the aggregation of fragrance beads. At its discharge end, it can guide the fragrance beads to disperse and flow outward, avoiding the accumulation of fragrance beads and blockage. At the same time, the guide roller 33 is split into a first roller 331 and a second roller 332, so that the narrower part in the middle of the guide roller 33 passes through the first through hole 11, avoiding the large-sized first through hole 11 from affecting the dispersing effect of the fragrance bead cluster. Furthermore, through the cooperation of the limiting block 333 and the limiting groove 334, relative rotation between the first roller 331 and the second roller 332 is prevented, ensuring that the fragrance beads can flow along the guide groove.

[0030] In this embodiment of the application, a plurality of the guide grooves are spirally arranged around the outer periphery of the guide roller 33.

[0031] Both the first extrusion protrusion 12 and the second extrusion protrusion 13 are annular. The first extrusion protrusion 12 includes a first protrusion 121 and a first recess 122 arranged coaxially from the inside to the outside. The second extrusion protrusion 13 includes a second recess 131 and a second protrusion 132 arranged coaxially from the inside to the outside. The first protrusion 121 cooperates with the guide roller 33 to extrude the fragrance beads. The first recess 122 provides storage and flow space for the dispersed fragrance beads. The second recess 131 forms a clearance space to facilitate the aggregation of fragrance beads. The second protrusion 132 occupies the center position of the guide mechanism 34 to prevent the fragrance beads from touching the bottom and failing to contact the guide arm 344, thus affecting the flow.

[0032] The storage bin 31 includes a storage hopper 311, a guide cylinder 312, and multiple first connecting ports 313. The storage hopper 311 is a hollow shell with an open bottom, and the diameter of its inner wall gradually narrows towards the side away from the partition 32. The guide cylinder 312 is disposed through the middle of the storage hopper 311. Multiple first connecting ports 313 are sequentially arranged around the periphery of the guide cylinder 312 and are all connected to the interior of the storage hopper 311. The dispensing cylinder 4 includes a cylinder body 41, a limiting mechanism 42, and multiple second connecting ports 43. The cylinder body 41 passes through the outer cover 2 and slides with the guide cylinder 312. The limiting mechanism 42 connects the cylinder body 41 and the guide cylinder 312. A plurality of second connecting ports 43 are sequentially arranged around the periphery of the cylinder 41 and are respectively connected to a plurality of first connecting ports 313. The storage hopper 311 temporarily stores fragrance beads and flows into the cylinder 41 through the plurality of first connecting ports 313 and the plurality of second connecting ports 43. The guide cylinder 312 guides the feeding cylinder 4, and when the cylinder 41 slides, the limiting mechanism 42 restricts the sliding range of the cylinder 41 to prevent the cylinder 41 from sliding excessively and causing it to detach, or the bottom of the cylinder 41 from being lower than the first connecting port 313 and causing the fragrance beads to enter the guide cylinder 312.

[0033] The limiting mechanism 42 includes two sliding grooves 421, two sliders 422, and a limiting plate 423. The two sliding grooves 421 are respectively located at the bottom of the outer periphery of the cylinder 41, and the two sliders 422 are respectively located on both sides of the inner wall of the guide cylinder 312. The two sliding grooves 421 and the two sliders 422 correspond to each other and slide in cooperation. The limiting plate 423 is connected to the bottom of the cylinder 41 by screws. The limiting plate 423 abuts against the sliders 422 to restrict the movement of the cylinder 41.

[0034] The outer periphery of the bottom of the inner cover 1 is provided with a first flange 14, and the inner periphery of the bottom of the outer cover 2 is provided with a movable groove 23 and a second flange 24 from top to bottom. The first flange 14 engages with the movable groove 23. The linkage mechanism includes multiple locking grooves 25 and multiple locking protrusions 26. The multiple locking grooves 25 surround the bottom edge of the abutment cylinder 21, and the multiple locking protrusions 26 surround the top of the inner cover 1, and each corresponds to and engages with one of the multiple locking grooves 25. While achieving rotational engagement, the movable groove 24 engages with the outer cover 24. The movable groove 23 provides a certain amount of space for the inner cover 1 and the outer cover 2 to move. When the outer cover 2 is pressed down, the snap-fit ​​groove 25 engages with the snap-fit ​​protrusion 26, and the outer cover 2 and the inner cover 1 can rotate synchronously. When the outer cover 2 is lifted up, the snap-fit ​​groove 25 and the snap-fit ​​protrusion 26 separate, and the outer cover 2 and the inner cover 1 can rotate relative to each other. In addition, since there is a snap-fit ​​structure between the inner cover 1 and the outer cover 2, it is difficult for infants and young children to align themselves, and there is a lack of sufficient pressure to trigger it, which hinders the opening of the cover by infants and young children and has a child lock function.

[0035] The present invention also provides a fragrance bead storage bottle, including a bottle body and a dispensing cap as described above. The bottle body has an external thread at the bottle opening and the inner circumference of the inner cap 1 has an internal thread. The internal thread and the external thread are threaded together. The bottle body stores fragrance beads. When fragrance beads are needed, the dispensing cap disperses and dispenses them in a measured amount.

[0036] In this embodiment, before use, the fragrance beads are poured into the bottle body. The inner cap 1 is fitted onto the bottle opening. The outer cap 2 is rotated, and the inner cap 1 is rotated via the linkage mechanism. The inner cap 1 and the bottle body rotate relative to each other and are fixed by a threaded connection. When the fragrance beads need to be taken out, the fragrance bead storage bottle is inverted, and the outer cap 2 is rotated. The outer cap 2 and the inner cap 1 rotate relative to each other. The separation component 3 rotates synchronously with the outer cap 2. The guiding mechanism 34 guides the clumps and individual fragrance beads in the bottle body into the guiding mechanism 34. During continuous rotation, more clumps and individual fragrance beads enter and are squeezed in the guiding mechanism 34. Large clumps of fragrance beads are squeezed and broken into smaller clumps. The smaller clumps and individual fragrance beads enter the squeezing channel 5. Inside, the guide roller 33 guides the flow of small clumps and individual fragrance beads and cooperates with the first extrusion protrusion 12 to completely break the clumps of small fragrance beads into individual beads. The individual fragrance beads enter the storage bin 31 for temporary storage through multiple connecting grooves 35. When the dispensing cylinder 4 is located inside the guide cylinder 312, multiple first connecting ports 313 and multiple second connecting ports 43 are connected one-to-one. The individual fragrance beads in the storage bin 31 enter the cylinder 41. When the cylinder 41 slides relative to the guide cylinder 312 and extends out of the outer cover 2, multiple second connecting ports 43 are connected to the outside. The fragrance beads in the cylinder 41 flow out to achieve quantitative dispensing. At this time, the top of the cylinder 41 abuts against multiple first connecting ports 313 to prevent the fragrance beads in the storage bin 31 from continuing to flow out.
