Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology for packaging bottles, specifically to a perfume bottling and filling kit. Background Technology

[0002] Currently available perfume bottling and filling kits on the market mostly have the filling component slots at the bottom molded as a single piece on the bottom of the bottle. The filling component is directly inserted into the slot to form a fixed assembly. The sealing between the filling component and the assembly slot relies solely on the sealing ring fixed to the outer ring of the filling component. The sealing effect depends entirely on the tightness of the locking between the filling component and the slot. Therefore, the precision requirements for the production of parts are extremely high, and the tolerance range for the dimensional tolerances of each component is low during the assembly process.

[0003] Therefore, we propose a perfume bottling and filling kit that is easy to assemble and has good sealing properties. Utility Model Content

[0004] This invention provides a perfume bottling and filling kit to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] This utility model discloses a perfume bottling and filling kit, specifically including a bottle body. The bottom of the bottle body is provided with an assembly part for assembling a filling component. A retaining ring is fastened to the outside of the assembly part to fix the filling component to the inside of the assembly part. In order to prevent the retaining ring from falling off the assembly part, a buckle is fitted on the outside of the retaining ring to clamp and position it. The buckle, together with the retaining ring, limits the retaining ring from the outside, which can effectively prevent the retaining ring from falling off the assembly part. This ensures that the filling component inside can maintain its initial sealed state for a long time, which can effectively prevent the volatile top notes in the perfume from evaporating and being lost prematurely. Thus, the perfume can still maintain a relatively stable top, middle and base notes even after long-term storage.

[0007] Furthermore, the liquid filling assembly specifically includes: a plastic fastener and a fixed inner buckle that are fastened together. After the plastic fastener and the fixed inner buckle are fastened together, a cylindrical assembly cavity is left between the plastic fastener and the fixed inner buckle. The liquid filling assembly also includes a guide and a liquid filling valve core assembly installed inside the assembly cavity. The guide is sleeved on the outside of the liquid filling valve core assembly. On the one hand, it supports the assembly cavity formed between the plastic fastener and the fixed inner buckle. On the other hand, it axially positions the movement direction of the liquid filling valve core assembly, ensuring that the liquid filling valve core assembly can move back and forth along the length direction of the guide, thereby realizing the opening and closing action of the liquid filling operation.

[0008] Furthermore, to improve the tolerance range of the plastic fastener and the inner wall of the assembly part during production, the plastic fastener includes a spur cap inserted into the inner side of the assembly part, and several sealing rings are provided between the outer side of the spur cap and the inner side of the assembly part. Additionally, a horizontally designed positioning ring is integrally formed at the bottom end of the spur cap, facing outwards. The positioning ring is tightly attached to the lower edge of the assembly part. Normally, the sealing ring extends horizontally outwards. After the spur cap of the plastic fastener is inserted into the inner side of the assembly part, the sealing ring deforms under the pressure of the assembly part, firmly forming a closed structure within the tolerance gap between the inner side of the assembly part and the spur cap. The positioning ring is designed primarily to prevent the spur cap from being over-inserted into the assembly part, and also to facilitate the formation of an L-shaped transition platform after the positioning ring contacts the lower edge of the assembly part, as well as to facilitate an effective assembly and fixing connection between the fastener and the inner fixing clip.

[0009] Furthermore, the fixing inner buckle includes an annular fixing groove with a "Z"-shaped cross-section, and the top of the fixing groove is tightly attached to the positioning ring. The edge of the top of the fixing groove is folded over from the outside of the positioning ring and covers the outer edge of the fixing ring to form an edge buckle. Through the structural design of the plastic fastener and the fixing inner buckle, the outer side of the entire liquid filling assembly forms multiple annular platforms, forming a complex annular stepped transition platform. This facilitates the use of the retaining ring and the buckle to perform multi-layer sealing treatment on the outer side of the liquid filling assembly, thereby improving the sealing performance between the liquid filling assembly and the assembly part.

[0010] Furthermore, the guide includes a positioning cap that is hollow inside and cylindrical in shape. The top of the positioning cap is provided with a positioning groove, and a sealing sleeve is provided in the positioning groove. The top of the sealing sleeve is inserted into the assembly hole. Under the action of the sealing sleeve, the top of the guide forms an annular gap around the circumference of the sealing sleeve as an exhaust chamber.

[0011] Furthermore, to enable the filling valve core to smoothly replenish or fill the internal space of the bottle, an assembly hole is provided at the center of the top of the cap to facilitate the passage of the filling valve core assembly. Specifically, the filling valve core assembly includes a filling column, with a filling hole on its side near the top. The top of the filling column slides upwards through the guide and is inserted into the sealing sleeve. Under normal conditions, the filling hole is located inside the sealing sleeve and is closed. To maintain the airtightness of the filling valve core assembly under normal conditions, and also to facilitate... After the filling is completed, the filling valve core assembly can automatically reset and return to the closed state. An integrally formed support ring is located on the outer side of the filling column head near the bottom, which slides with the inner side of the guide. A spring is provided between the top of the support ring and the top of the inner side of the guide, which is sleeved on the outer side of the filling column head. A rubber push block is sleeved on the outer side of the filling column head at the bottom of the support ring. The rubber push block slides with the inner side of the guide. One end of the spring abuts against the inner side of the guide, applying a downward force to the support ring, so that the filling hole on the filling column head retracts back into the sealing sleeve to achieve closure.

[0012] Furthermore, to reduce the impact of internal air pressure on the filling speed during the filling process, an exhaust port is provided on the side of the top of the spiked cap, communicating with the assembly cavity inside the spiked cap. An exhaust pipe is connected to this exhaust port, with its end extending to near the top of the bottle. The exhaust port and exhaust pipe are sealed together. Simultaneously, exhaust guide grooves are provided at equal intervals around the circumference of the positioning cap, and an exhaust notch is provided at the bottom of the positioning cap corresponding to each exhaust guide groove. The exhaust pipe, exhaust chamber, and exhaust guide... The groove and the vent opening form an air circulation channel. When perfume is filled into the bottle, the air inside the bottle is simultaneously squeezed out by the perfume and enters the vent chamber through the vent pipe and then through the vent. It is then guided by the vent guide groove to the bottom of the guide and finally discharged to the outside through the vent opening from the hole in the middle of the fixed groove. In order to accelerate the air discharge speed, the entire air circulation channel is set on the outside of the guide. Moreover, with the help of several vent guide grooves and the annular vent chamber designed around the circumference of the guide, the problem of poor air discharge caused by the narrow channel can be minimized.

[0013] Meanwhile, to minimize the airtightness issues caused by dimensional tolerances during component assembly and to improve the tolerance range during component production, the retaining rings securing the liquid filling components adopt a louvered structure design, as detailed below:

[0014] Furthermore, the retaining ring specifically includes an annular base that fits tightly against the bottom edge of the fixing groove, thereby firmly clamping the fixing groove to the lower edge of the assembly part. In addition, the outer edge of the top of the base is integrally formed with several claw teeth that cooperate with the assembly part at equal intervals around the circumference. The inner side of the top of each claw tooth is integrally formed with an anti-detachment claw buckle. The assembly part includes an annular retaining groove with an anti-detachment ring at the edge for cooperating with the anti-detachment claw buckle on the retaining ring. The width and depth of the retaining groove are adapted to the size of the anti-detachment claw buckle at the front end of the claw tooth. When the anti-detachment claw buckle is engaged in the retaining groove and cooperates with the anti-detachment ring, the upper and lower ends of the anti-detachment claw buckle just abut against the sides of the retaining groove, so that the claw tooth cannot move up and down along the bottle body, firmly locking the filling component inside the assembly part.

[0015] Furthermore, to prevent the retaining ring from rotating on the assembly part, a number of positioning ribs are provided at equal intervals around the anti-detachment ring on the retaining groove. The position of the positioning ribs corresponds to the position of the gap left between adjacent claw teeth in the retaining ring. When the retaining ring is fastened and fixed to the assembly part, the positioning ribs are stuck in the gap on the side of the corresponding claw teeth, which not only plays a positioning role, but also strengthens the structural strength of the assembly part.

[0016] Furthermore, to prevent the buckle from detaching from the outside of the retaining ring and to further improve the sealing of the entire filling kit, a horizontally positioned anti-detachment protrusion is integrally formed on the outer side of each claw tooth at the same height. Moreover, the buckle includes an outer buckle cap that fits around the entire outside of the retaining ring and is designed in a ring shape, and an anti-detachment groove that is integrally formed on the inner side of the outer buckle cap at the position corresponding to the anti-detachment protrusion. A collar is provided in the gap between the outer buckle cap and the base in the retaining ring. The collar is either a rubber sealing gasket or a magnetic ring.

[0017] The advantages of this utility model over the prior art are as follows:

[0018] The liquid-filling assembly proposed in this utility model utilizes a snap-fit ​​ring to engage with the assembly part for fixed assembly. Through the louvered structure design of the snap-fit ​​ring and the multiple layers of sealing rings designed on the outside of the plastic fixing parts that make up the liquid-filling assembly, the problem of insufficient airtightness caused by dimensional tolerances during parts assembly can be avoided to the greatest extent. Compared with traditional liquid-filling assemblies, it has a more tolerant range of tolerances in the dimensional tolerances of the parts during production. Moreover, with the design of the buckle ring, the snap-fit ​​ring is limited from the outside, which can effectively prevent the snap-fit ​​ring from loosening from the assembly part, thereby ensuring that the liquid-filling assembly on the inside can maintain its initial airtight state for a long time. This can effectively prevent the volatile top notes in the perfume from evaporating and being lost prematurely, so that the perfume can still maintain a relatively stable top, middle and base notes even after long-term storage.

[0030] Example

[0031] To address the issue that existing perfume bottling and filling kits on the market rely solely on a sealing ring fixed to the outer ring of the filling component to ensure a tight seal between the filling component and the mounting slot 201, the sealing effect depends entirely on the tightness of the engagement between the filling component and the slot 201. This places extremely high demands on the precision of component manufacturing and results in a low tolerance range for dimensional errors in each part. Therefore, we propose a perfume bottling and filling kit that is simple to assemble and provides excellent sealing, as shown below:

[0032] like Figures 1-3 As shown in the figure, the perfume bottling and filling kit provided in this embodiment specifically includes a bottle body 1. The bottom of the bottle body 1 is provided with a mounting part 2 for mounting the filling component. A retaining ring 11 for fixing the filling component to the inner side of the mounting part 2 is fastened to the outer side of the mounting part 2. In order to prevent the retaining ring 11 from falling off the mounting part 2, a buckle 12 is fitted on the outer side of the retaining ring 11 to clamp and position the outer side of the retaining ring 11. The buckle 12 limits the retaining ring 11 from the outside, which can effectively prevent the retaining ring 11 from falling off the mounting part 2, thereby ensuring that the inner filling component can maintain the initial sealed state for a long time. This can effectively prevent the volatile top notes in the perfume in the bottle from evaporating and being lost in advance, so that the perfume can still maintain a relatively stable top note, middle note and base note performance during long-term storage.

[0033] In this embodiment, the liquid filling assembly specifically includes: a plastic fastener 3 and a fixed inner buckle 5 fastened together. After the plastic fastener 3 and the fixed inner buckle 5 fasten together, a cylindrical assembly cavity is left between the plastic fastener 3 and the fixed inner buckle 5. The liquid filling assembly also includes a guide 6 and a liquid filling valve core assembly 7 respectively installed inside the assembly cavity. The guide 6 is sleeved on the outside of the liquid filling valve core assembly 7. On the one hand, it supports the assembly cavity formed between the plastic fastener 3 and the fixed inner buckle 5. On the other hand, it axially positions the movement direction of the liquid filling valve core assembly 7, ensuring that the liquid filling valve core assembly 7 can move back and forth along the length direction of the guide 6, thereby realizing the opening and closing action of the liquid filling operation.

[0034] In this embodiment, as Figure 2As shown, in order to improve the tolerance range of the plastic fastener 3 and the inner wall of the assembly part 2 during production, the plastic fastener 3 includes a sill plug 301 inserted into the inner side of the assembly part 2, and a plurality of sealing rings 302 are provided between the outer side of the sill plug 301 and the inner side of the assembly part 2. Furthermore, a horizontally designed positioning ring 305 is integrally formed at the bottom end of the sill plug 301, facing outwards. The positioning ring 305 is tightly attached to the lower edge of the assembly part 2. The sealing rings 302 extend horizontally outwards under normal conditions, while... After the sill plug 301 of the plastic fastener 3 is inserted into the inner side of the assembly part 2, the sealing ring 302 is deformed under the compression of the assembly part 2, and forms a closed structure firmly within the tolerance gap between the inner side of the assembly part 2 and the sill plug 301. The design of the positioning ring 305 is mainly to prevent the sill plug 301 from being over-inserted into the assembly part 2. It also facilitates the formation of an L-shaped transition platform after the positioning ring 305 contacts the lower edge of the assembly part 2, and facilitates an effective assembly and fixing connection between the fixing part and the fixing inner buckle 5.

[0035] In this embodiment, as Figures 1-2 As shown, the fixing inner buckle 5 includes an annular fixing groove 501 with a "Z" shaped cross-section. The top of the fixing groove 501 is tightly attached to the positioning ring 305. The edge of the top of the fixing groove 501 is folded over from the outside of the positioning ring 305 and covers the outer edge of the fixing ring to form an edge buckle 502. Through the structural design of the plastic fastener 3 and the fixing inner buckle 5, the outer side of the entire liquid filling assembly forms multiple annular platforms, forming a complex annular stepped transition platform. This facilitates the locking ring 11 to cooperate with the buckle ring 12 to perform multi-layer sealing treatment on the outer side of the liquid filling assembly, thereby improving the sealing performance between the liquid filling assembly and the assembly part 2.

[0036] In this embodiment, as Figures 1-2 As shown, the guide member 6 includes a positioning cap 601 that is hollow inside and cylindrical in shape. The top of the positioning cap 601 is provided with a positioning groove 602. A sealing sleeve 8 is provided in the positioning groove 602. The top of the sealing sleeve 8 is inserted into the assembly hole 303. Under the action of the sealing sleeve 8, the top of the guide member 6 forms an annular gap around the circumference of the sealing sleeve 8 as an exhaust chamber.

[0037] In this embodiment, as Figures 1-2As shown, in order to enable the filling valve core to smoothly replenish or fill the internal space of the bottle body 1, an assembly hole 303 is provided at the center of the top of the cap 301 to facilitate the passage of the filling valve core assembly 7. Specifically, the filling valve core assembly 7 includes a filling column 701, and a filling hole 703 is provided on the side of the filling column 701 near the top. The top of the filling column 701 slides upward from the inside of the guide 6 and passes through the guide 6 before being inserted into the sealing sleeve 8. Under normal conditions, the filling hole 703 is located inside the sealing sleeve 8 and is in a closed state. In order to maintain the airtightness of the filling valve core assembly 7 under normal conditions, and also to facilitate the automatic reset of the filling valve core assembly 7 to return to the closed state after filling, an integrally formed filling hole 303 is provided on the outside of the filling column 701 near the bottom. A ring 702 slides within the guide member 6, and a spring 704 is fitted around the outside of the filling head 701 between the top of the ring 702 and the top of the guide member 6. A rubber pusher 9 is fitted around the outside of the filling head 701 at the bottom of the ring 702, and this rubber pusher 9 slides within the guide member 6. One end of the spring 704 abuts against the inside of the guide member 6, applying a downward force to the ring 702, causing the filling hole 703 on the filling head 701 to retract back into the sealing sleeve 8 to achieve closure. It should be noted that the filling valve core assembly 7 adopts a conventional valve core mechanism in the field. How to achieve filling and how to automatically reset and self-close after filling are all conventional technologies in this field. Therefore, the working principle and venting mechanism of the filling valve core assembly 7 will not be described in detail.

[0038] Furthermore, to reduce the impact of internal air pressure on the filling speed during the filling process, an exhaust port 304 is provided on the side of the top of the spiked cap 301, communicating with the assembly cavity inside the spiked cap 301. An exhaust pipe 4 is connected to this exhaust port 304, with its end extending to near the top of the bottle body 1. The exhaust port 304 and the exhaust pipe 4 are connected in a sealed assembly. Simultaneously, exhaust guide grooves 603 are provided at equal intervals around the circumference on the outer side of the positioning cap 601, and an exhaust notch is provided at the bottom of the positioning cap 601 corresponding to each exhaust guide groove 603. The exhaust pipe 4, exhaust chamber, and exhaust guide... The flow channel 603 and the exhaust opening form an air circulation channel. When perfume is filled into the bottle 1, the air that is simultaneously squeezed out of the bottle 1 due to the perfume passes through the exhaust pipe 4 and enters the exhaust chamber through the exhaust port 304. Then, it is guided by the exhaust guide channel 603 to the bottom of the guide member 6 and finally discharged to the outside through the exhaust opening from the hole in the middle of the fixed groove 501. In order to accelerate the air discharge speed, the entire air circulation channel is set on the outside of the guide member 6. Moreover, with the help of several exhaust guide channels 603 and the annular exhaust chamber designed around the circumference on the outside of the guide member 6, the problem of poor exhaust due to the narrow channel can be minimized.

[0039] Meanwhile, in order to minimize the airtightness issues caused by dimensional tolerances during component assembly and to improve the tolerance range during component production, the retaining ring 11 of the fixed liquid filling component adopts a louvered structure design, as detailed below:

[0040] In this embodiment, as Figures 2-3 As shown, the retaining ring 11 specifically includes an annular base 111, which fits tightly against the bottom edge of the fixing groove 501, thereby firmly clamping the fixing groove 501 onto the lower edge of the assembly part 2. Additionally, the outer edge of the top of the base 111 is integrally formed with a plurality of claw teeth 112 at equal intervals around the circumference, which cooperate with the assembly part 2. Each claw tooth 112 has an anti-disengagement claw buckle 113 integrally formed on the inner side of its top. The assembly part 2 includes an annular retaining groove 201, the edge of which... The anti-detachment ring 202 is used to cooperate with the anti-detachment claw buckle 113 on the retaining ring 11. The width and depth of the retaining groove 201 are adapted to the size of the anti-detachment claw buckle 113 at the front end of the claw tooth 112. When the anti-detachment claw buckle 113 is engaged in the retaining groove 201 and cooperates with the anti-detachment ring 202, the upper and lower ends of the anti-detachment claw buckle 113 just abut against the sides of the retaining groove 201, so that the claw tooth 112 cannot move up and down along the bottle body 1, and firmly locks the liquid filling component inside the assembly part 2.

[0041] To prevent the retaining ring 11 from rotating on the assembly part 2, a number of positioning ribs 203 are provided at equal intervals around the anti-detachment ring 202 on the retaining groove 201. The position of the positioning ribs 203 corresponds to the gap position left between adjacent claw teeth 112 in the retaining ring 11. When the retaining ring 11 is fastened and fixed to the assembly part 2, the positioning ribs 203 are stuck in the gap on the side of the corresponding claw teeth 112, which not only plays a positioning role, but also strengthens the structural strength of the assembly part 2.

[0042] To prevent the retaining ring 12 from detaching from the outside of the retaining ring 11, and to further improve the sealing of the entire filling kit, a horizontally positioned anti-detachment protrusion 114 is integrally formed on the outer side of each claw tooth 112 at the same height. Furthermore, the retaining ring 12 includes an outer cap 121 that fits over the entire retaining ring 11 and is ring-shaped, and an anti-detachment groove 122 integrally formed on the inner side of the outer cap 121 at a position corresponding to the anti-detachment protrusion 114, which is adapted to the anti-detachment protrusion 114. The outer cap 121 and... A collar 10 is provided in the gap between the base 111 in the retaining ring 11. The collar 10 is either a rubber sealing gasket or a magnetic ring. When the collar 10 is a rubber sealing gasket, it can further improve the sealing performance of the filling kit. When the collar 10 is a magnetic ring, it can make the end of the filling kit at the bottom of the bottle form a magnetic attraction effect. Moreover, by using the magnetic ring to fill the gap between the outer cap 121 and the base 111, the stability of the structure between the outer cap 121 and the base 111 can also be improved.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
