Description

Technical Field

[0001] This utility model relates to the field of vacuum bottle technology, and in particular to a vacuum bottle with a dual-head design. Background Technology

[0002] In the cosmetics packaging industry, the design of lotion bottles is crucial for product preservation, user experience, and hygiene. Traditional lotion bottles often use a piston pump design with a straw, requiring the bottle to be open to the outside atmosphere to balance pressure. This makes the lotion inside prone to drying out due to solvent evaporation, and when the lotion is almost used up, the straw cannot easily suck up the lotion around the bottom of the bottle, resulting in waste. To solve these problems, vacuum lotion bottles have emerged. Vacuum lotion bottles have openings at both the top and bottom. The piston inside the bottle and the bottle body below the top form a cavity for holding the lotion. When the lotion level decreases, the vacuum pump device at the top uses the pressure difference inside and outside the cavity to push the piston upward, thus pushing the lotion upward. However, existing vacuum lotion bottles still have many shortcomings. On the one hand, existing vacuum lotion bottles mostly rely on pressing the vacuum pump head to squeeze out the lotion, and the pressing pressure is difficult to control precisely, resulting in unstable and uneven dispensing, which affects the user experience. On the other hand, the usual way to take and apply lotion is to press the pump to dispense the lotion into the palm of the hand and then apply it directly to the face, or to use a brush, powder puff, or other tools to pick up the lotion from the palm of the hand and then apply it. This method is not only cumbersome, but also easily contaminates the lotion with the palm and tools, posing a hygiene risk.

[0003] Therefore, some lotion bottles that integrate the dispensing and application functions have appeared on the market, such as the Chinese utility model patent "A Rotating Dispensing Vacuum Lotion Bottle" (patent number 202123255263.11, authorization announcement number CN217446957U). It uses a sponge-like application head set on the top for application, which improves the convenience of use to a certain extent. However, this integrated design also brings new problems.

[0004] From a hygiene perspective, the applicator head is constantly exposed, making it prone to accumulating dust, bacteria, and other contaminants. During use, these contaminants can easily enter the bottle and contaminate the lotion, threatening the user's skin health. Regarding ease of use, because the dispensing and application functions are closely linked, it's difficult to precisely control the dispensing volume. This makes it inconvenient and wasteful in situations requiring localized application to small areas or precise dosage control. Furthermore, cleaning and maintenance are challenging. Lotion residue easily accumulates at the connection between the applicator head and the dispensing channel, which is difficult to remove completely with ordinary cleaning methods. Long-term accumulation of dirt can breed bacteria and produce odors. Replacing the applicator head is also complex due to its highly integrated structure, increasing both usage costs and time.

[0005] In summary, existing emulsion bottle technology has shortcomings in terms of uniformity of liquid dispensing, ease of use, hygiene, and cleaning and maintenance, and a more advanced vacuum emulsion bottle design is urgently needed to solve these problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a vacuum bottle with a dual-head design that separates the liquid dispensing and coating functions through a split design, thereby improving hygiene, liquid dispensing accuracy and convenience.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the vacuum bottle with dual-head usage includes...

[0008] The bottle assembly has an opening at its top;

[0009] A pump assembly is located at the top opening of the bottle assembly, and has a pressing member that can move up and down and a resetting member that drives the pressing member to reset. The pump assembly communicates with the inside of the bottle assembly through the opening and forms a liquid outlet channel.

[0010] A drive sleeve is movably mounted on the bottle assembly and can drive the pressing element to move downward during the movement of the bottle to output the contents through the liquid outlet channel;

[0011] An applicator head, located at the bottom of the bottle assembly, is used to apply the liquid discharged from the liquid outlet channel.

[0012] To more stably control the movement of the pressing component and achieve precise liquid dispensing, preferably, the driving sleeve is rotatably fitted onto the bottle assembly. A convex ring is formed on the outer circumferential surface of the bottle assembly, and an annular groove adapted to the convex ring is formed on the inner circumferential surface of the driving sleeve. A ratchet-shaped lifting track is formed on the inner side of the driving sleeve, and a protrusion that cooperates with the lifting track is provided on the outer side of the pressing component. By rotating the driving sleeve, the protrusion can be driven to move along the lifting track, forcing the pressing component to move up and down to achieve pressing or resetting.

[0013] To optimize the overall structure of the bottle assembly and enable the pump assembly to be better installed on the bottle assembly, preferably, the bottle assembly includes a bottle body and a mounting sleeve disposed on the top of the bottle body. The top of the bottle body has an upwardly extending insertion portion, and the bottom of the mounting sleeve has an insertion hole for the insertion portion to be inserted from bottom to top. The pump assembly is disposed on the mounting sleeve and communicates with the interior of the bottle body. The drive sleeve is disposed on the mounting sleeve, and the convex ring is formed on the outer peripheral surface of the mounting sleeve.

[0014] To ensure that the pressing component can only move up and down relative to the mounting sleeve under the drive of the drive sleeve, preferably, the mounting sleeve has vertically extending guide ribs, and the pressing component has guide grooves corresponding to the guide ribs. The pressing component is constrained to move up and down relative to the mounting sleeve by the guide adaptation between the guide ribs and the guide grooves.

[0015] To better position the applicator head at the bottom of the bottle, the bottle preferably includes a body and a bottom detachably connected to the bottom of the body, wherein the bottom of the bottom has a mounting groove for mounting the applicator head.

[0016] In order to enable the pump assembly to better form a liquid outlet channel, preferably, the pump assembly further includes a pump core and a discharge component, the pressing component is connected between the pump core and the discharge component, the discharge component has a discharge hole, the reset component is located inside the pump core, and the contents inside the bottle assembly are discharged outward from bottom to top through the pump core, the pressing component and the discharge component.

[0017] To ensure a better connection between the pressing component and the discharge component, and to guarantee the sealing and smooth flow of liquid transmission, preferably, the pressing component has a downwardly extending first connecting pipe and an upwardly extending second connecting pipe. The first connecting pipe is inserted into and connected to the pump core. The discharge component also has a downwardly extending guide pipe for the second connecting pipe to move up and down. The top of the discharge component has an obliquely shaped contact surface for contacting human skin. The discharge hole passes through the contact surface and connects to the guide pipe.

[0018] In order to enable the discharge component to be smoothly connected to the drive sleeve, preferably, the drive sleeve has an upwardly extending first annular wall, and the discharge component has a downwardly extending second annular wall that fits inside the first annular wall. The inner circumferential surface of the first annular wall has a plurality of buckles arranged circumferentially at intervals, and the outer circumferential surface of the second annular wall has an annular buckle groove for the buckles to fit and rotate circumferentially.

[0019] In order to enable the applicator head to better conform to the skin of different parts and improve the comfort and evenness of application, so as to meet the diverse needs of users, preferably, the surface of the applicator head is a flexible contact surface, and the contour of the flexible contact surface is a plane, a curved surface or a roller.

[0020] To better protect the discharge port and applicator head and prevent contaminants such as dust and bacteria from entering, thereby maintaining the cleanliness and hygiene of the product, preferably, a first protective cover for sealing the discharge port is detachably fitted on the drive sleeve, and a second protective cover for sealing the applicator head is detachably fitted on the bottom of the bottle.

[0021] Compared with existing technologies, the advantages of this utility model are as follows: In terms of structural design, by setting the pump assembly and the applicator head at the top and bottom of the bottle assembly respectively, the dispensing and applicating functions are successfully integrated. Users do not need to use additional tools to apply the lotion as in the traditional way, which greatly simplifies the operation process and brings convenience to daily use. On the other hand, the dispensing part and the applicator part are separated in both directions without interference. The applicator head only comes into contact with the dispensed lotion when in use, avoiding direct contact with unused lotion. The split design also makes daily cleaning easier. When not in use, the applicator head and pump assembly can be protected by the matching protective cover, effectively reducing the contamination of dust, bacteria and other pollutants. In addition, by setting a drive sleeve to precisely control the movement of the pressing part, users can easily and accurately control the dispensing volume in scenarios such as local care where precise dispensing volume is required, avoiding waste and greatly improving efficiency. With the tight cooperation of the reset part and the pressing part, the continuity and stability of the dispensing volume are ensured. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Figures 1-6 The diagram shown is a schematic diagram of this embodiment. The vacuum bottle with dual-head usage in this embodiment mainly includes a bottle body assembly 1, a pump assembly 2, a drive sleeve 3, and an applicator head 4, etc.

[0030] Assembly of the overall structure: Reference Figures 1 to 5As shown, in this embodiment, the bottle assembly 1 consists of a bottle body 11 and a mounting sleeve 12. The top of the bottle body 11 forms an upwardly extending insertion portion 11a, and the bottom of the mounting sleeve 12 has an insertion hole 12a for the insertion portion 11a to be inserted from bottom to top, thus connecting the two. A drive sleeve 3 is rotatably fitted onto the bottle assembly 1. The outer circumferential surface of the mounting sleeve 12 of the bottle assembly 1 has a protruding ring 1b, and the inner circumferential surface of the drive sleeve 3 has an annular groove 3a that matches the protruding ring 1b. The rotational adaptation of the protruding ring 1b and the annular groove 3a serves to position and limit movement. The pump assembly 2 is mounted on the mounting sleeve 12. The protrusion 2a1 on the outer side of the pressing member 2a in the pump assembly 2 engages with a ratchet-shaped lifting track 3b located inside the drive sleeve 3. Rotating the drive sleeve 3 drives the protrusion 2a1 to move along the corresponding lifting track 3b, forcing the pressing member 2a to move up and down to achieve pressing or resetting. Meanwhile, the guide rib 12b formed on the mounting sleeve 12 is adapted to the guide groove 2a2 formed on the pressing member 2a, ensuring that the pressing member 2a can only move up and down relative to the mounting sleeve 12.

[0031] Specific structure of pump fluid assembly 2: See reference Figures 3 to 5 As shown, in this embodiment, the pump assembly 2 includes a pump core 2c, a discharge component 2d, a pressing component 2a, and a reset component 2b. The reset component 2b is a compression spring and is disposed inside the pump core 2c. The pressing component 2a is connected between the pump core 2c and the discharge component 2d. The pressing component 2a has a downwardly extending first connecting pipe 2a3 and an upwardly extending second connecting pipe 2a4. The discharge component 2d has a discharge hole 2d1. The first connecting pipe 2a3 on the pressing component 2a is inserted into and connected to the pump core 2c. The guide pipe 2d2 on the discharge component 2d allows the second connecting pipe 2a4 of the pressing component 2a to move up and down. The discharge component 2d also has a downwardly extending guide pipe 2d2 for the second connecting pipe 2a4 to move up and down. The contact surface 2d3 at the top of the discharge component 2d is oblique to facilitate contact with human skin. The discharge hole 2d1 penetrates the contact surface 2d3 and connects to the guide pipe 2d2.

[0032] The drive sleeve 3 has an upwardly extending first annular wall 3c, and the discharge part 2d has a downwardly extending second annular wall 2d4 that fits inside the first annular wall 3c. The buckle 3d provided on the inner circumferential surface of the first annular wall 3c cooperates with the annular buckle groove 2d5 provided on the outer circumferential surface of the second annular wall 2d4 to realize the rotational connection between the discharge part 2d and the drive sleeve 3. When the drive sleeve 3 rotates, the discharge part 2d does not need to rotate synchronously with the drive sleeve 3.

[0033] Installation of bottle 11 and applicator 4: Refer to Figures 2 to 5As shown, in this embodiment, the bottle body 11 consists of a bottle body 111 and a bottle bottom 112, with the bottle bottom 112 detachably connected to the bottom of the bottle body 111. The mounting groove 113 at the bottom of the bottle bottom 112 is used to mount the applicator head 4. The surface of the applicator head 4 is a flexible contact surface, and its contour can be flat, curved, or roller-shaped to adapt to different applicator needs.

[0034] Specific installation instructions for protective devices: Refer to Figure 6 As shown, in this embodiment, a first protective cover 5 is detachably fitted onto the drive sleeve 3 to seal the discharge hole 2d1; a second protective cover 6 is detachably fitted onto the bottle bottom 112 to seal the first protective cover 5 and the applicator head 4, thereby providing protection.

[0035] The working principle of the vacuum bottle with dual-head operation in this embodiment is as follows: When emulsion needs to be dispensed, the drive sleeve 3 is rotated. The drive sleeve 3 rotates around the bottle assembly 1 through the engagement of the annular groove 3a and the convex ring 1b. Since the protrusion 2a1 on the pressing member 2a engages with the ratchet-shaped lifting track 3b on the inner side of the drive sleeve 3, the rotation of the drive sleeve 3 will drive the protrusion 2a1 to move along the corresponding lifting track 3b, thereby forcing the pressing member 2a to move up and down. Under the action of the pressing member 2a, the emulsion inside the bottle assembly 1 can pass from bottom to top through the pump core 2c, the pressing member 2a, and the dispensing member 2d, and finally be discharged from the dispensing hole 2d1. When the drive sleeve 3 is stopped from rotating, the reset member 2b will drive the pressing member 2a to reset, waiting for the next operation. When applying emulsion, the applicator head 4 installed on the bottom of the bottle 112 can be used directly to pick up the emulsion discharged from the dispensing hole 2d1 onto the skin, and then applied to the skin. To clean or replace the applicator head 4, the applicator head 4 can be removed from the bottle bottom 112; to clean the dispensing part 2d, the dispensing part 2d can be removed from the mounting sleeve 12 for cleaning.
