Description

Technical Field

[0001] This utility model relates to the technical field of cosmetic packaging containers, and in particular to the technical field of vacuum bottles with rotatable bases. Background Technology

[0002] Currently, most vacuum bottles on the market use a direct press-to-open method, with the press head often exposed, making it susceptible to contamination and inconvenient to carry. Some products feature retractable structures, but these typically suffer from issues such as uneven lifting, unreliable positioning, or complex structures. For example, some rotating lifting mechanisms are prone to jamming or wobbling during lifting, affecting the user experience. Furthermore, the inner liner of most products is not replaceable, leading to the disposal of the entire bottle, which is not environmentally friendly. Therefore, there is an urgent need for a vacuum bottle that operates smoothly, positions precisely, has a reliable structure, and allows for a replaceable inner liner. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a rotatable vacuum bottle with a unique groove and rail mechanism that enables smooth and stable extension and retraction of the pressing head, and also provides a replaceable inner liner.

[0004] To achieve the above objectives, this utility model proposes a rotatable vacuum bottle, comprising a bottle body, a rotatable inner shell, a rotatable base, a lifting housing, and an inner liner assembly. The lower part of the inner wall of the bottle body has symmetrical rectangular guide grooves. The rotatable inner shell is rotatably disposed within the bottle body, and its upper part has obliquely symmetrical lifting grooves. These lifting grooves include a vertical section, a horizontal limiting section, and an inclined lifting section arranged from top to bottom, with the top of the vertical section opening onto the top surface of the rotatable inner shell. The rotatable base is drively connected to the rotatable inner shell. The guide post of the lifting housing is housed within the lifting groove. The rotating base can drive the inner shell to rotate, and through the cooperation of the lifting groove and the guide post, the lifting housing carries the inner liner assembly up and down. Crucially, during the rotation and ascent of the lifting housing, its guide post slides into the rectangular guide groove of the bottle body after entering the upper part of the inclined lifting section of the lifting groove, thereby achieving the smooth extension or retraction of the pressing head.

[0005] Preferably, the horizontal limiting section extends horizontally to the left from the lower end of the vertical section, limiting the guide column when the lifting housing is raised to its highest position; the tilting lifting section extends tilted downwards to the right from the lower end of the vertical section, and its end extends horizontally to the right to form a lower horizontal limiting section, limiting the guide column when the lifting housing is lowered to its lowest position. The advantage of this structure is that precise mechanical locking at both ends of the lifting stroke is achieved through the two horizontal limiting sections, effectively preventing the inner liner from sinking when pressed at the highest point or the pressing head from loosening and shaking when carried at the lowest point, thus improving the product's structural stability and reliability.

[0006] Preferably, the tilting angle of the lifting section is 45 degrees. This preferred angle has the advantage of achieving an optimal balance between rotational operating force and lifting efficiency, resulting in smooth and effortless operation.

[0007] Preferably, the rotatable inner shell and the rotatable base are connected by the meshing of transmission teeth and the inner teeth of the base. This structure offers the advantage of precise and reliable transmission, ensuring the synchronization of rotational and lifting movements.

[0008] Preferably, the rotatable base is pressed onto the lower outer periphery of the rotatable inner shell from below, and the connection is achieved through the engagement of an annular protrusion and a second annular groove. The advantages of this structure are simple assembly, a secure connection, and effective prevention of the base from falling off during use, thus improving the overall structural integrity.

[0009] Preferably, the inner cavity of the pump head has an annular structure, and the top of the annular structure has a transverse flow channel with a D-shaped cross-section, with the end of the flow channel extending out of the pump head. The advantages of this structure are smooth liquid dispensing, less residue, and the extended portion makes it easy to pick up cosmetics.

[0010] Preferably, the extended portion of the press head mates with the arc-shaped notch on the top surface of the bottle. This structure offers the advantage of a perfect fit with the bottle when the press head retracts, resulting in a clean appearance and dust protection, thus enhancing the product's aesthetics and hygiene.

[0011] Preferably, the inner liner assembly is a replaceable structure, comprising an inner liner shell, a seal sealed to the bottom of the inner liner shell's inner cavity, an inner liner base located at the bottom of the inner liner shell, a pump assembly installed inside the inner liner shell, a sealing ring located between the pump assembly and the top surface of the inner liner shell, and a bottle head threadedly fixed to the head of the inner liner shell, with a pressing head engaged in a limiting groove within the bottle head. The advantages of this structure are that it constitutes a complete, reliable, and independent vacuum system, ensuring the sealing of the contents and smooth access; simultaneously, the replaceable design greatly improves the product's environmental friendliness and economy.

[0012] Preferably, the upper part of the inner wall of the bottle has a radial protrusion to vertically limit the press head in the retracted state. This structure ensures the stability of the press head in the retracted state.

[0013] The beneficial effects of this utility model are: 1. Smooth operation and precise positioning: Through the mechanism that "the guide column cooperates with the bottle guide groove at the upper part of the inclined lifting section", the lifting process can obtain precise vertical guidance in most of the stroke, ensuring that the pressing head can be lifted and lowered smoothly without jamming, and can be stably locked in both the extended and retracted positions.

[0014] 2. Reliable structure and good load-bearing capacity: The horizontal limiting section in the lifting groove can effectively withstand the downward pressure generated when using the pressing head, preventing the internal mechanism from retracting and improving the structural strength and durability of the product.

[0015] 3. Easy replacement and convenient maintenance: The vertical section at the top of the lifting channel leads directly to the top surface of the inner shell. When replacing the inner liner, simply rotate the guide column to the top of the inclined lifting section, and then pull the entire inner liner assembly out directly downwards. No complicated disassembly is required, which greatly improves the convenience of maintenance.

[0016] 4. Comprehensive functions and excellent user experience: The replaceable inner liner design reduces long-term usage costs for users and is environmentally friendly and economical; the matching design of the press head and the notch in the bottle body ensures cleanliness and sealing when stored.

[0017] 5. Stable transmission and easy assembly: Power transmission is accurate and reliable through gear meshing; the base is quickly and firmly assembled by the fit between the annular protrusion and the pressure sleeve of the second annular groove, and it can effectively prevent detachment.

[0018] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

The upper part of the inner wall surface has radial protrusions 11. The lower part of the inner wall surface also has a convex strip 13 with a semi-circular cross-section. The top surface has an arc-shaped notch 14.

[0030] Rotatable inner shell 2, such as Figure 3 As shown, the inner shell 21 is press-fitted into the bottle body 1 by the first annular groove 22 on its outer surface and the protrusion 13, allowing it to rotate. The two obliquely symmetrical lifting grooves 21 on its upper part are the core of this design. Each lifting groove 21 includes a vertical section 211, a horizontal limiting section 212, an inclined lifting section 213, and a lower horizontal limiting section 214 arranged from top to bottom. The top of the vertical section 211 opens directly onto the top surface of the rotatable inner shell 2; this design primarily facilitates the installation and replacement of the inner liner assembly. The lower outer circumference of the rotatable inner shell 2 also has circumferentially distributed transmission teeth 23 and a second annular groove 24 for engaging with the base.

[0031] Rotatable base 3, such as Figure 4 As shown, it is pressed from below onto the outside of the rotatable inner shell 2. The lower part of its inner wall is provided with a base inner tooth 31 that meshes with the transmission tooth 23, and the upper part of its inner wall is provided with an annular protrusion 32 that cooperates with the second annular groove 24 of the rotatable inner shell 2.

[0032] Lifting housing 4, such as Figure 3 and Figure 5 As shown, its guide post 41 is housed in the lifting groove 21.

[0033] The inner liner assembly, a replaceable structure, is housed within the lifting housing 4. It is the core component enabling vacuum liquid storage and press-to-dispense functions.

[0034] like Figure 6As shown, the inner shell 51, the sealing element 52, and the inner base 53 together constitute the liquid storage and sealing lifting system of the vacuum bottle.

[0035] like Figure 7 As shown, the pump assembly 54 is installed inside the inner shell 51 and is sealed to the top surface of the inner shell 51 by a sealing ring 55.

[0036] like Figure 8 As shown, the bottle head 56 is fixed to the head of the inner shell 51 by threads, which is used to press the sealing ring 55 and fix the pump assembly 54.

[0037] like Figure 9 As shown, the pressing head 57 is locked in the limiting groove of the bottle head 56. Its inner cavity is provided with an annular structure 571. The top of the annular structure 571 is provided with a transverse flow channel 572 with a D-shaped cross section. The end of the flow channel extends out of the pressing head and matches the arc-shaped notch 14 on the top surface of the bottle body 1.

[0038] The working process of this utility model: The working process of this utility model's rotatable vacuum bottle base is explained in conjunction with the accompanying drawings.

[0039] Extension process: The user rotates the rotatable base 3 clockwise → Through the meshing of the inner teeth 31 and the transmission teeth 23, the rotatable inner shell 2 rotates synchronously → The wall of the inclined lifting section 213 of the lifting groove 21 pushes the guide column 41 upward → During this process, after the guide column 41 enters the upper part of the inclined lifting section 213, it slides into the rectangular guide groove 12 of the bottle body 1 to obtain precise vertical guidance → Finally, the guide column 41 slides into the horizontal limiting section 212, the lifting shell 4 rises to the highest point, the pressing head 57 is fully extended, and it is in a ready state that can be pressed down and used.

[0040] Retraction process: The user rotates the rotatable base 3 counterclockwise → the rotatable inner shell 2 rotates in the opposite direction → the groove wall of the lifting groove 21 drives the guide column 41 to slide down along the inclined lifting section 213 → the lifting shell 4 carries the inner vacuum bottle 5 down as a whole → the guide column 41 finally slides into the lower horizontal limit section 214, the lifting shell 4 drops to the lowest point, the pressing head 57 is completely retracted into the bottle body 1, its upper surface is limited by the radial protrusion 11 of the bottle body 1, cannot be pressed down, and is in a stable storage state.

[0041] Inner liner replacement process: When the inner liner needs to be replaced, the user rotates the rotatable base 3, causing the guide column 41 of the lifting housing 4 to move to the top of the inclined lifting section 213 of the lifting groove 21 (i.e., the lower end of the vertical section 211). At this time, the user does not need to continue rotating; simply apply downward force to pull the guide column 41 through the vertical section 211 from the top opening of the rotatable inner shell 2, thereby removing the entire inner liner assembly and the lifting housing 4 together for replacement. The operation is extremely convenient.

[0042] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
