Description

Technical Field

[0001] This utility model belongs to the field of cosmetic packaging equipment technology, and more specifically relates to a vacuum bottle processing device. Background Technology

[0002] The choice and design of cosmetic packaging not only affects the product's appearance but also directly impacts its quality, stability, and the consumer experience. Product design requires comprehensive consideration of multiple factors, including product compatibility, seal integrity, barrier properties, aesthetic appeal, and physical properties during distribution, to ensure the product meets consumer needs. Among these factors, seal integrity is particularly crucial. This is because most cosmetic active ingredients are highly volatile complexes, and many natural extracts are prone to discoloration and deterioration upon contact with air, affecting product efficacy and safety. Therefore, an increasing number of cosmetic brands are choosing vacuum bottles for their packaging. Vacuum bottles, through their unique vacuum pump dispensing system, achieve uniform and consistent dispensing, while the effective volume decreases as the amount of product decreases, effectively preventing the entry of outside air. This design not only protects the active ingredients and extends the product's shelf life but also enhances the consumer experience. Furthermore, the vacuum pump allows for almost complete dispensing of the contents, resulting in less residue compared to other packaging methods, making it more environmentally friendly and economical, and its application in the cosmetics and skincare industry is becoming increasingly widespread.

[0003] The vacuum bottle filling process is a crucial step in the entire production process, directly impacting the end consumer's experience and satisfaction with the product. The filling process requires degassing the material and minimizing air ingress. If excessive gas or large voids remain inside the bottle after filling, it can lead to problems such as excessive spraying cycles, spray interruptions, and material pump failures. Ideally, cosmetic vacuum bottle packaging involves placing the filling and sealing processes in a vacuum environment; however, this requires significant equipment investment and is difficult for manufacturers to implement. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a vacuum bottle processing device that can automatically adjust the effective capacity of the vacuum bottle according to the net content requirements.

[0005] The objective can be achieved by a vacuum bottle processing device, the vacuum bottle processing device being used to adjust the piston position of a vacuum bottle, characterized in that the vacuum bottle processing device comprises:

[0006] - A working platform with a piston for placing a vacuum bottle, the platform being designed so that the bottle can be placed upside down on the platform with its vacuum pump side facing the platform.

[0007] - At least one cover for covering a bottle on a work platform to isolate the bottle from the surrounding environment.

[0008] - A pressure gas generating device for supplying pressure gas, wherein the pressure gas supplied by the pressure gas generating device can be passed into the cap, through a through hole at the bottom of the bottle, and thereby apply pressure to the piston inside the bottle so as to press the piston down;

[0009] - At least one pressurized gas delivery line for delivering pressurized gas, connected between the pressurized gas generating device and the cover; and

[0010] - A target height control component for controlling the target height of the piston, the target height control component is arranged on the work platform and the structure and size of the target height control component are designed such that the bottle can be placed upside down on the work platform at the position of the target height control component and the target height control component can be located inside the bottle when the bottle is upside down.

[0011] Using the vacuum bottle processing equipment according to this disclosure can meet quality requirements such as the number of spray cycles and pump output while reducing production costs. In particular, the vacuum bottle processing equipment according to this disclosure ensures filling quality requirements. By using the vacuum bottle processing equipment, the piston height can be increased as needed to reduce the space inside the vacuum bottle after filling, thereby reducing the number of spray cycles and significantly reducing the risk of interrupted spraying, further enhancing product stability and reliability. The vacuum bottle processing equipment according to this disclosure allows the piston to be adjusted to the target height before filling, thus meeting both spray cycle requirements and subsequent usage requirements. Furthermore, the vacuum bottle processing equipment according to this disclosure reduces production costs. This vacuum bottle processing equipment requires low fixed asset investment and relatively low labor costs in production operations, which helps enterprises optimize resource allocation and improve overall operational efficiency. In addition, this vacuum bottle processing equipment exhibits high flexibility and adaptability, allowing for flexible adjustment of the effective volume of packaging materials according to actual needs. This not only meets the packaging needs of diverse products but also ensures that production efficiency remains at the same level as conventional products, effectively guaranteeing the smooth and efficient operation of the production line. Furthermore, the aforementioned vacuum bottle processing equipment can also save material. After adopting this equipment, the inner packaging volume is no longer filled by increasing the filling volume, reducing content consumption. Where the filling equipment's accuracy allows, the filling volume per bottle can be appropriately reduced. Taking a 50ml cream product as an example, before the improvement, the filling volume needed to be maintained at 52±1g to meet quality requirements such as the number of sprays. After adopting the vacuum bottle processing equipment disclosed herein, the filling volume can be reduced by 1g, i.e., 51±0.5g, while still meeting quality control requirements. Based on 1T of contents, this can produce approximately 377 more pieces of product, increasing the yield by 1.96%. These advantages maximize the packaging performance of the vacuum bottle, not only enhancing the product's market competitiveness but also bringing more considerable economic benefits to the enterprise. This invention allows for automatic adjustment of the effective capacity of the vacuum bottle according to net content requirements, reducing air contamination, ensuring the number of sprays, and reducing material consumption. This improves the consumer experience.

[0012] In some embodiments, the target height control element is configured as a stop that stops a piston within the bottle that is being pushed down by pressurized gas. When the cap covers the bottle and pressurized gas is introduced into the cap, the pressurized gas passing through a through-hole at the bottom of the bottle applies pressure to the piston within the bottle, thereby pushing the piston down until it is stopped by the stop. By employing the stop, very robust piston target height control can be achieved. Because of the stop, the pressurized gas pressure only needs to be sufficient to push the piston down, as the stop stops the piston from collapsing. Therefore, the pressurized gas pressure does not need to be adjusted too frequently for different bottle or piston sizes; instead, a higher pressure sufficient to push down most of the piston within the bottle can be used. This reduces the technical requirements of the pressurized gas generating device, thereby controlling costs.

[0013] In some embodiments, a scale or ruler is provided on the target height control element, the scale or ruler being configured to display the length of the target height control element and thereby display the target height of the piston. This allows for intuitive identification of the set target height value.

[0014] In some embodiments, the pressurized gas delivery line is constructed as a flexible hose. This facilitates operation, as the hose itself is flexible and easier for the operator to handle, for example, by holding the cover with their hand. Furthermore, the hose is more cost-effective.

[0015] In some embodiments, a switching device is provided in the pressurized gas delivery line and / or on the cover. This switching device is configured to connect and disconnect the fluid connection between the pressurized gas generating device and the cover. This allows for the connection and disconnection of the fluid connection between the pressurized gas generating device and the cover as needed. It also facilitates the switching control of the gas delivery. Furthermore, a switching device can be provided in the pressurized gas delivery line or on the cover as needed. A switching device on the cover allows for easy operation by the operator while holding the cover, while a switching device in the pressurized gas delivery line facilitates pre-switching control.

[0016] In some embodiments, the switching device is equipped with a press element, which, when pressed down, opens the switching device to connect the fluid connection between the pressurized gas generating device and the cover. This press element can be manually controlled, for example. When the switching device is arranged on the cover and also includes a press element, the following advantageous technical effects can be achieved: on the one hand, the press element can be manually pressed to open the switching device and connect the fluid connection; on the other hand, the pressing force can be transmitted to the cover via the press element to ensure good isolation from the surrounding environment. Thus, the dual functions of opening the switching device and pressing down the cover are achieved simultaneously with a simple and convenient pressing operation.

[0017] In some embodiments, the switching device is configured as a valve.

[0018] In some embodiments, the valve is a multi-way valve to which multiple covers can be connected, allowing for selective pressurized gas delivery to the multiple covers. Thus, by configuring the valve as a multi-way valve, multi-channel switching control can be achieved.

[0019] In some embodiments, a one-to-one connection structure exists between the pressurized gas delivery lines and the covers, wherein one of the at least one pressurized gas delivery lines is correspondingly matched with one of the at least one covers; or

[0020] A one-to-many connection structure exists between the pressurized gas delivery pipeline and the cover. In this structure, one of the at least one pressurized gas delivery pipelines is paired with multiple covers. Each pressurized gas delivery pipeline includes a main pipeline section and multiple branch pipeline sections branching off from the main pipeline section at branch points. These branch pipeline sections are respectively connected to the multiple covers. Therefore, either a one-to-one or one-to-many connection structure can be used as needed. In a one-to-one connection structure, each cover is equipped with one pressurized gas delivery pipeline, thus allowing for a parallel structure. In a one-to-many connection structure, the pressurized gas delivery pipeline can be divided into a main pipeline section and multiple branch pipeline sections, with each branch pipeline section connected to a cover, thus allowing for a main-branch structure.

[0021] In some embodiments, in the one-to-one connection structure, a corresponding switching device is arranged in the corresponding pressurized gas delivery pipeline; or in the one-to-many connection structure, a switching device is arranged in the main pipeline section and / or at the branch points and / or in each branch pipeline section. Thus, for both the one-to-one and one-to-many connection structures, switching devices can be installed at corresponding locations in the pressurized gas delivery pipeline as needed.

[0022] In some implementations, when a switching device is arranged at the branch point, the switching device is configured as a multi-way valve. This enables multi-way switching control.

[0023] In some embodiments, the vacuum bottle processing equipment includes a gas purification device integrated into or located upstream of the pressurized gas generating device. This gas purification device is configured to purify the gas to be processed by the pressurized gas generating device. Thus, the gas used to generate the pressurized gas can be purified, for example, through sterilization and / or filtration.

[0024] In some embodiments, the gas to be processed by the pressurized gas generating device is air.

[0025] In some embodiments, the pressurized gas generating device includes a compressor, the compression mechanism of which compresses gas entering the pressurized gas generating device to generate pressurized air. Thus, pressurized gas can advantageously be generated by a compressor.

[0026] In some embodiments, the stop is configured with a fixed height, which is set according to the desired target height of the piston. This allows for stable target height control.

[0027] In some embodiments, the stop is constructed as a column.

[0028] In some embodiments, the stop is configured to be height-adjustable, comprising a base and a height adjustment member movable relative to the base to adjust the height and lockable at the adjusted height position, wherein the height adjustment member is configured to provide a stop. This allows for flexible target height control. The stop height can be adjusted on-site as needed to meet different target height control requirements of the vacuum bottle piston.

[0029] In some embodiments, a mating structure exists between the base and the height adjustment component, allowing the height adjustment component to be adjusted in multiple positions or steplessly relative to the base. Therefore, multiple positions or stepless adjustment can be used to obtain different target height control positions according to actual needs.

[0030] In some embodiments, the base is provided with a plurality of slots spaced apart from each other along the height direction, and the height adjustment member has a protrusion on its circumferential surface that can engage with any one of the plurality of slots to achieve multi-level height adjustment. Thus, multi-level adjustment can be advantageously achieved by means of the slot structure.

[0031] In some embodiments, the mating structure between the base and the height adjustment component is a threaded connection, allowing for stepless height adjustment by screwing the height adjustment component relative to the base. Thus, stepless adjustment can be advantageously achieved through the threaded connection structure.

[0032] In some embodiments, the threaded engagement structure is self-locking and / or the height adjustment element is locked relative to the base by a lock nut to maintain it at the adjusted height position. This allows for locking of the infinitely adjustable height position.

[0033] In some embodiments, the working platform has a flat surface. This allows for a close fit between the bottle opening of the vacuum bottle and the cap opening on the working platform.

[0034] In some embodiments, the vacuum bottle handling equipment is configured to adjust the piston position on-site during filling and packaging. This allows for more flexible piston position adjustment, enabling adjustments to be made on-site. Attached Figure Description

[0045] Firstly, by using Figure 1 Describe the structure of vacuum bottle 1 itself. For example... Figure 1 As shown, a commonly used vacuum bottle 1 mainly includes a vacuum pump 11, a bottle body 12, and a movable piston 13. The piston 13 is arranged and installed inside the bottle body 12, creating a sealed space between itself and the upper bottle head or mouth, where the material is stored. By pressing the pressure head of the vacuum pump 11, a vacuum state is created in the space. Using external atmospheric pressure, the piston 13 is pushed to move through the vent hole or through-hole 14 at the bottom of the bottle body 12, thereby dispensing the material through the liquid outlet of the vacuum pump 11.

[0046] The technical problem to be solved by this utility model is to provide a vacuum bottle processing device that can adjust the height of the piston 13 as needed, such as reducing the material storage space. The following is an explanation of... Figures 2 to 6 The layout structure and working principle of the vacuum bottle processing equipment according to this utility model are described.

[0047] like Figures 2 to 6 As shown, this vacuum bottle handling device for adjusting the position of the piston 13 of the vacuum bottle 1 includes: a working platform 2 for placing the vacuum bottle 1 with a bottle body 12 having the piston 13, the working platform 2 being designed such that the bottle body 12 can be placed upside down on the working platform 2 with its vacuum pump side opening facing the working platform 2; at least one cover 3 for covering the bottle body 12 on the working platform 2 to isolate the bottle body 12 from the surrounding environment; and a pressure gas generating device 4 for providing pressure gas, the pressure gas provided by the pressure gas generating device 4 being able to be passed into the cover 3 and through the bottom of the bottle body 12. A through-hole 14 thereby applies pressure to a piston 13 inside the bottle body 12 to press the piston 13 downward; at least one pressurized gas delivery line 5 connecting the pressurized gas generating device 4 and the cover 3 for delivering pressurized gas; and a target height control member 6 for controlling the target height of the piston 13, the target height control member 6 being arranged on the work platform 2 and the structure and dimensions of the target height control member 6 being designed such that the bottle body 12 can be placed upside down on the work platform 2 at the position of the target height control member 6 and the target height control member 6 can be located inside the bottle body 12 in the upside-down state.

[0048] As from Figures 2 to 4As can be clearly seen, the target height control element 6 is configured as a stop that can stop the piston 13 in the bottle body 12 from being pressed downward by pressurized gas. When the cover 3 covers the bottle body 12 and pressurized gas is introduced into the cover 3, the pressurized gas passing through the through-hole 14 at the bottom of the bottle body 12 applies pressure to the piston 13 inside the bottle body 12, especially to the piston 13 at the very bottom of the bottle body 12 (e.g., Figure 2 (As shown) and thus presses piston 13 downward until piston 13 stops against the stop (as shown). Figure 3 (As shown). For example, combined with Figure 2 and Figure 3 As can be seen, when pressurized gas is introduced into the cover 3 through the gas inlet on the cover 3, especially on the top of the cover 3, the pressurized gas acts on the piston 13 through the through hole 14 of the bottle body 12. Under the action of gas pressure, the piston 13 is pressed downward in the direction of the arrow until it stops on the stop member. As mentioned above, due to the presence of the stop member, the pressure provided by the pressurized gas is sufficient to press the piston 13 down to meet the usage requirements. Therefore, the pressure regulation of the pressurized gas has less technical requirements, thereby controlling the cost. In this embodiment, the height of the target height control member 6 for the stop member is fixed. This fixed height can be set according to the desired target height of the piston 13. In particular, the stop member is constructed as a columnar member, such as a cylinder. Of course, other forms of columns, such as prisms or cuboids, can also be conceived. In addition to the fixed stop member, a height-adjustable stop member can also be conceived. The target height control member 6 for the height-adjustable stop member will be described later.

[0049] In addition, such as from Figures 2 to 4 As can be seen, a scale 7 is arranged on the target height control member 6, which is constructed as a stop member. The scale 7 can be used to display the length of the target height control member 6 and thus the target height of the piston 13. Alternatively, it is conceivable to set a scale directly on the target height control member 6, which can also be used to display the length of the target height control member 6 and thus the target height of the piston 13.

[0050] In this invention, the cover 3 can be manually operated by the operator. To facilitate manual operation by the operator, the pressurized gas delivery pipeline 5 is constructed as a flexible hose.

[0051] In order to enable or disable the fluid connection between the pressurized gas generating device 4 and the cover 3 as needed, such as Figure 2 As shown, in one embodiment, a switching device 8 configured as a valve can be provided in the pressurized gas delivery line 5. In such a case... Figure 2In the illustrated embodiment, a pressurized gas delivery pipeline 5 and a cover 3 are provided, which is a one-to-one connection structure, i.e., one pressurized gas delivery pipeline 5 is paired with one cover 3. Therefore, only one switching device 8 is provided. It is also conceivable that multiple covers 3 are provided, which can simultaneously operate multiple vacuum bottles 1 to improve work efficiency. For this purpose, two methods can be adopted: Method one is to adopt a one-to-one connection structure between the pressurized gas delivery pipeline 5 and the cover 3, with multiple pressurized gas delivery pipelines 5 respectively paired with multiple covers 3 in a one-to-one correspondence; Method two is to adopt a one-to-many connection structure between the pressurized gas delivery pipeline 5 and the cover 3, i.e., one pressurized gas delivery pipeline 5 can be paired with multiple covers 3, wherein this one pressurized gas delivery pipeline 5 may include a main pipeline section 51 and multiple branch pipeline sections 52 branching from the main pipeline section 51 at branch points, with the branch pipeline sections 52 respectively connected to the multiple covers 3. For the one-to-one connection structure, see as follows... Figure 2 and Figure 6 The illustrated embodiment. For a one-to-many connection structure, see [link to example]. Figure 4 and Figure 5 The example shown. In Figure 4 and Figure 5 In the illustrated embodiment, a pressurized gas delivery line 5 is coupled to two covers 3. The pressurized gas delivery line 5 includes a main line section 51 and two branch line sections 52 branching from the main line section 51 at branch points. These two branch line sections 52 are respectively connected to the two covers 3. Figure 4 and Figure 5 In the illustrated embodiment, a switching device 8 configured as a multi-way valve is arranged at the branch point. This multi-way valve enables selective supply of pressurized gas to these covers 3, for example, supplying pressurized gas to one or more covers 3 as needed to adjust the height of the piston 13 of one or more vacuum bottles 1, or supplying pressurized gas to all covers 3 to adjust the height of the piston 13 of all vacuum bottles 1. Figure 4 and Figure 5 The difference is that, Figure 4 The switching device 8 can be automatically controlled, and Figure 5 The switching device 8 can be manually controlled. To achieve manual control, such as... Figure 5 As shown, the switch device 8 may be equipped with a pressing member 81, which can be pressed down to open the switch device 8 so as to connect the fluid connection between the pressure gas generating device 4 and the cover 3.

[0052] It should be noted that, in a one-to-many connection structure, in addition to the switch device 8 being installed at the branch point, it is also conceivable to additionally or alternatively arrange the switch device 8 in the main pipeline section 51 and / or in each branch pipeline section 52.

[0053] The above describes different embodiments of arranging the switching device 8 in the pressurized gas transmission pipeline 5. The following describes the use of… Figure 6 Describe another arrangement of the switching device 8.

[0054] like Figure 6 As shown, a switching device 8 for connecting and disconnecting the fluid connection between the pressurized gas generating device 4 and the cover 3 can also be arranged on the cover 3. In this embodiment, the switching device 8 is equipped with a pressing member 81, which can be pressed down to open the switching device 8. This configuration combination achieves the following advantages: on the one hand, the pressing member 81 can be manually pressed to open the switching device 8 and connect the fluid connection; on the other hand, the pressing force can be transmitted to the cover 3 via the pressing member 81 to ensure good isolation from the surrounding environment. Therefore, Figure 6 This configuration is very convenient and reliable for manual operation.

[0055] It should be noted that, Figure 5 and Figure 6 For clarity, the stop is not depicted in the text, but it does exist in actual applications.

[0056] Next, using Figure 4 Other functional devices of the vacuum bottle processing equipment are described. When adjusting the vacuum bottle 1 using the pneumatic piston 13, since the vacuum bottle 1 has high requirements for gas cleanliness, the vacuum bottle processing equipment includes a gas purification device 41 for purifying, such as filtering and / or sterilizing, the gas to be processed by the pressurized gas generating device 4. This gas purification device 41 can be as follows: Figure 4 The gas is integrated into the pressurized gas generating device 4. In another embodiment, the gas purification device 41 may also be arranged upstream of the pressurized gas generating device 4. To control costs, the gas to be processed by the pressurized gas generating device 4 can be air. Of course, in some embodiments, other safe gases, such as nitrogen, are also conceivable. To generate pressurized gas, such as... Figure 4 As shown, the pressurized gas generating device 4 also includes a compressor 42 configured to compress the gas entering the pressurized gas generating device 4 to generate pressurized air. Additionally, a pump 9 is arranged upstream of the pressurized gas generating device 4, by means of which gas, such as air, can be pumped to the pressurized gas generating device 4.

[0057] In addition to the fixed-height stop described above, a height-adjustable stop can also be envisioned. The following section uses... Figures 7 to 9 Two different embodiments of a target height control member 6, configured as a height-adjustable stop, are described.

[0058] The target height control member 6, configured as a height-adjustable stop, includes a base 61 and a height adjustment member 62 that is movable relative to the base 61 to adjust the height and can be locked at the adjusted height position. The height adjustment member 62 is configured to provide a stop. Figure 7 and Figure 8 As shown, a mating structure exists between the base 61 and the height adjustment component 62, allowing the height adjustment component 62 to be adjusted to multiple positions relative to the base 61. In this mating structure, the base 61 has multiple slots 64 spaced apart along the height direction. The height adjustment component 62 has a protrusion 63 that can engage with any one of the multiple slots 64 to achieve multi-position height adjustment. Figure 8 As shown, in one embodiment, each slot 64 may have a downwardly recessed portion 65 at its innermost point, allowing the protrusion 63 of the height adjustment member 62 to ultimately fall into the recessed portion 65 for locking, thereby preventing the height adjustment member 62 from disengaging from the base 61. Furthermore, it is conceivable that, in cases such as... Figure 9 In the illustrated embodiment, an additional mating structure exists between the base 61 and the height adjustment member 62, which enables stepless adjustment of the base 61 relative to the height adjustment member 62. This additional mating structure can be configured as a threaded engagement structure, allowing stepless height adjustment by screwing the height adjustment member 62 relative to the base 61. This threaded engagement structure can be self-locking. Alternatively or supplementarily, as... Figure 9 As shown, the height adjustment component 62 is locked relative to the base 61 by a locking nut 66 to fix the height adjustment component 62 and thus maintain it at the adjusted height position. It should be noted that... Figures 7 to 9 All embodiments involve height adjustment of the height adjustment member 62 within the base 61. In other embodiments, it is also conceivable that the height adjustment member 62 is fitted outside the base 61, and the corresponding matching structure can be adjusted to achieve similar multi-level adjustment and stepless adjustment functions.
