[0033] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 14 As shown, a press-discharge vacuum bottle of the present embodiment comprises a shell 1, a receiving cavity 11 capable of receiving fluid material is provided in the shell 1, a dispensing assembly capable of pressing and taking out the fluid material is provided on the shell 1, the dispensing assembly comprises a storage channel 2 and a dispensing channel 3, which are interconnected, the dispensing assembly further comprises a pressing portion 4, a dispensing portion 5 and a drawing portion 6, the drawing portion 6 is located between the storage channel 2 and the receiving cavity 11, the pressing portion 4 is arranged corresponding to the storage channel 2, the dispensing portion 5 is arranged corresponding to the dispensing channel 3, and the two are interconnected, the dispensing portion 5 is maintained in a normally closed state to prevent air from entering the receiving cavity 11 or the fluid material from flowing out on its own;

[0035] When using fluid materials (such as cosmetics) for the first time, the user can press the pressing part 4, and the pressing part 4 compresses the space between the pressing part 4 and the storage channel 2, so that negative pressure is formed inside the storage channel 2. When the force on the pressing part 4 is removed, the pressing part 4 returns to its original state. In the process of returning to its original state, the fluid material in the accommodating cavity 11 is sucked into the storage channel 2 through the extraction part 6, and then the pressing part 4 is pressed again. The pressing part 4 can force the fluid material in the storage channel 2 to transfer to the discharge channel 3, and the fluid material in the discharge channel 3 can force the discharge part 5 to switch to an open state, thereby guiding the fluid material to be discharged from the outside. Then, after the force on the pressing part 4 is removed again, the extraction part 6 again absorbs the fluid material into the storage channel 2 to prepare for the next discharge action.

[0036] This design can keep the fluid in the shell 1 from contacting the outside air at all times, thereby avoiding problems such as oxidation of the fluid material, water evaporation / contamination, and microbial contamination, thereby maintaining the stability of the product and extending its service life, ensuring the safety of the fluid material and the user experience.

[0037] like Figures 1 to 14 As shown, the discharge portion 5 of this embodiment is a discharge incision, which remains closed in a default state, thereby preventing accidental leakage of cosmetics or other fluid materials and air and pollutants from entering the shell through the discharge incision.

[0038] Furthermore, designing the discharge portion as a cutout can simplify the switch mechanism because no complicated valves or nozzles are required, thereby reducing manufacturing costs and failure rates.

[0039] When the user presses the pressing part 4, the fluid material inside the storage channel 2 is forced to flow to the discharge channel 3, and finally discharged through the discharge incision 5. Since the pressure of the fluid material will force the discharge incision to open, the fluid material can only be discharged when the pressing part is pressed down. After releasing the pressing part, the discharge incision will automatically close due to the reduction in internal pressure. At the same time, the extraction part 6 will use negative pressure to suck the fluid material from the accommodating cavity 11 into the storage channel 2 again for the next use.

[0040] With this design, the discharge cutout remains normally closed after the pressing portion is released, ensuring that the fluid material does not come into contact with the air when not in use, thereby maintaining its stability and quality.

[0041] Preferably, the material dispensing assembly of this embodiment is located at the top of the shell 1; the user can naturally press the pressing part 4 on the top. This design is usually in line with the user's operating habits and is easy to operate with one hand.

[0042] Furthermore, the top-mounted dispensing assembly can reduce the risk of fluid material leakage when the bottle is tipped or inverted.

[0043] Furthermore, the top-configured dispensing assembly can make the bottle design more compact, reducing the need for additional operating space at the bottom or sides, making the bottle more suitable for compact packaging.

[0044] Furthermore, it is generally easier to clean because the discharge is concentrated in one area, avoiding the cleaning difficulties that may arise from multiple discharge points.

[0045] like Figures 1 to 14 As shown, the material extraction part 6 of this embodiment includes a one-way valve plug opened by negative pressure, and the bottom of the material storage channel 2 is provided with an assembly part 21 communicating therewith, the one-way valve plug is assembled into the assembly part 21, and the input end of the one-way valve plug extends into the accommodating chamber 11;

[0046] Specifically, the design of the one-way valve plug only allows the material to pass in one direction, that is, to flow from the accommodating chamber 11 to the storage channel 2. When the user stops applying pressure to the pressing portion 4 and the pressing portion 4 gradually recovers elastically, the negative pressure formed in the storage channel will open the one-way valve plug, allowing the material in the accommodating chamber to be filled into the storage channel for the next use.

[0047] Specifically, the assembly portion 21 is located at the bottom of the material storage channel 2 and communicates therewith, providing a position for installing the one-way valve plug, so that the one-way valve plug can be accurately installed at the correct position where the flow of material needs to be controlled.

[0048] Furthermore, the input end of the one-way valve plug extends into the accommodating chamber 11, which means that each time it is used, the material in the accommodating chamber can directly enter the one-way valve plug through the input end. This design ensures that even when the amount of material in the accommodating chamber is low, the one-way valve plug can still effectively extract material from the bottom of the accommodating chamber.

[0049] The advantage of this liquid extraction mechanism is that during use, as the material is continuously extracted, it ensures that the material can be extracted smoothly with each press, thus improving the user experience.

[0050] Furthermore, due to the characteristics of the one-way valve plug, it is ensured that the material that has been drawn into the material storage channel 2 will not flow back into the accommodating chamber 11 due to external pressure, thereby reducing the risk of contamination that may be caused by the backflow of materials.

[0051] Furthermore, the one-way valve plug can effectively control the amount of material to be extracted for use, which is helpful for users to master the usage amount, especially for products that require precise dosage such as medicines or high-end cosmetics.

[0052] like Figures 1 to 14 As shown, the assembly portion 21 of the present embodiment includes an assembly protrusion extending into the accommodating cavity 11, and an assembly hole 211 is provided at the bottom of the assembly protrusion. A latch 61 is provided on the valve body of the one-way valve plug, and the one-way valve plug is connected to the assembly hole 211 through the latch 61. Specifically, by inserting and fixing the latch 61 into the assembly hole 211, the one-way valve plug can be stably connected to the equipment without using glue, screws or other fixing methods. This connection method is simple, reliable, and convenient for future maintenance and replacement.

[0053] Specifically, this design simplifies the assembly process because the one-way valve plug can be installed in place by a simple "snapping" action, thereby reducing the complexity and cost of assembly.

[0054] Furthermore, when the one-way valve plug needs to be replaced or maintained, it can be easily removed from the assembly hole 211, providing better maintenance convenience.

[0055] Furthermore, the assembly protrusion structure provides a stable support, and the close fit between the latch and the assembly hole can provide a good anti-vibration effect, preventing the one-way valve plug from loosening or falling off during use.

[0056] Furthermore, this structural design can also ensure good sealing performance between the valve plug and the assembly part, further preventing liquid leakage and air backflow.

[0057] like Figures 1 to 14 As shown, the material extraction part 6 of this embodiment further includes a soft material bag disposed in the accommodating cavity 11, the soft material bag is in communication with the one-way valve plug, the fluid material is located in the soft material bag, and the one-way valve plug can absorb the fluid material into the material storage channel 2 through the soft material bag;

[0058] Specifically, a soft material bag is usually a flexible, squeezable packaging material, which can store fluid materials inside. During the suction process of the one-way valve plug, the soft material bag is continuously contracted and squeezed to force the fluid material inside it to move toward the one-way valve plug. When the external pressure is removed, due to the closure of the one-way valve plug, the soft material bag will not expand, and will continue to maintain the contracted state, continuously forcing the fluid material to prepare for the next discharging action. In addition, because the soft material bag can completely collapse when the material is used, the amount of remaining fluid material can be minimized to reduce waste.

[0059] Furthermore, by combining the one-way valve plug and the soft material bag, the use of a complex pump or piston structure can be avoided, the packaging and extraction system is simplified, the production cost can be reduced, and the user-friendliness is improved.

[0060] Furthermore, placing the material distribution component at the top means that the fluid material will be concentrated at the bottom of the soft material bag due to gravity when it is not pressed out, which helps to improve the suction efficiency of the fluid material when pressing.

[0061] like Figures 1 to 14 As shown, the volume of the material storage channel 2 of this embodiment is greater than the volume of the material discharge channel 3;

[0062] Specifically, the storage channel 2 has a relatively large volume, and a certain amount of fluid material can be temporarily stored therein for use in the next discharge.

[0063] Furthermore, a larger storage channel volume helps ensure a continuous supply of fluid material to the discharge channel 3, thereby reducing waiting time and improving efficiency.

[0064] Furthermore, the storage channel can serve as a pressure buffer. When the soft material bag is squeezed and the fluid flows into the storage channel, the larger storage channel can effectively relieve the pressure and prevent the fluid from flowing into the discharge channel too quickly and affecting the accuracy or causing leakage.

[0065] Furthermore, this different volume design can help to more accurately control the discharge amount each time, and also facilitate the estimated amount adjustment.

[0066] Furthermore, the compression space between the material storage channel 2 and the pressing portion 4 can be ensured, and the negative pressure generated in the material storage channel 2 can definitely enable the extraction portion 6 to extract the fluid material in the accommodating chamber 11 .

[0067] like Figures 1 to 14 As shown, a blocking component 7 is further provided between the storage channel 2 and the discharge channel 3 of the present embodiment. When the fluid material passes through the discharge channel 3, the blocking component 7 is opened to allow the fluid to flow out smoothly. When the discharge stops, the blocking component 7 is closed to prevent the fluid material in the discharge channel 3 from flowing back to the storage channel 2.

[0068] With such a design, the blocking assembly 7 helps to maintain the pressure state in the storage channel 2 and the discharge channel 3, ensuring smooth transportation and discharge of the fluid material.

[0069] Furthermore, the blocking component 7 can prevent the fluid material that has entered the discharge channel 3 from flowing back into the storage channel 2, which can effectively prevent the fluid that may have been contaminated from re-contaminating the material in the storage channel.

[0070] Furthermore, the barrier assembly can reduce material loss caused by backflow of fluid material due to operational problems or cessation of discharge operation.

[0071] Furthermore, for the user, the presence of the blocking component 7 can make the material discharge more stable during use, and will not cause material discharge problems or additional labor required for multiple pumping due to material backflow. Figures 1 to 14 As shown, the blocking assembly 7 of this embodiment includes a blocking channel 71 and a one-way elastic discharge plate 72, wherein the blocking channel 71 is arranged between the storage channel 2 and the discharge channel 3, and is respectively connected to the two, and the one-way elastic discharge plate 72 is arranged at one end of the blocking channel 71, and the one-way elastic discharge plate 72 can abut against the end of the blocking channel 71 to block the blocking channel 71; when the fluid material in the storage channel 2 moves toward the discharge channel 3, the one-way elastic discharge plate 72 can be elastically deformed and swing away from the end of the blocking channel 71, so that the blocking channel 71 is connected with the discharge channel 3;

[0072] In this embodiment, the one-way elastic discharge plate 72 is arranged on one end where the blocking channel 71 is connected to the discharge channel 3. The one-way elastic discharge plate 72 is usually in a closed state, fitting the end where the blocking channel is connected to the discharge channel 3 to prevent the fluid in the discharge channel 3 from flowing back into the storage channel 2.

[0073] Specifically, when the fluid material moves from the storage channel 2 to the discharge channel 3, the fluid pressure increases and acts on the one-way elastic discharge plate 72, causing it to elastically deform. Due to the design of the one-way elastic discharge plate 72, it can swing in one direction without abutting against the end of the blocking channel, thereby opening the blocking channel. At this time, the blocking channel 71 is connected to the discharge channel 3, and the fluid in the storage channel 2 can flow into the discharge channel 3.

[0074] When the discharge is completed, the pressure of the fluid on the one-way elastic discharge plate 72 disappears or decreases, and the one-way elastic discharge plate 72 will gradually return to its initial position due to the elastic recovery of its material. At this time, the one-way elastic discharge plate 72 is against the end of the blocking channel and returns to its original closed state, re-blocking the end of the blocking channel 71 to prevent backflow.

[0075] The key to this design lies in the elastic properties and one-way opening ability of the one-way elastic discharge plate 72, which allows the fluid to be discharged smoothly under a certain pressure, and automatically closes when there is no pressure or the pressure is reduced, thereby ensuring that the fluid does not flow back into the storage channel 2. Such a blocking component can ensure the one-way flow of fluid materials, provide higher discharge control accuracy, avoid pollution and material loss, and improve the sealing performance of the vacuum bottle.

[0076] like Figures 1 to 14 As shown, the shell 1 of this embodiment includes an outer shell 12 and a flip cover 13, and a hinge assembly 8 for hinged connection between the outer shell 12 and the flip cover 13 is provided between the outer shell 12 and the flip cover 13. A hidden portion 14 is also provided between the outer shell 12 and the flip cover 13, and the hinge assembly 8 is located in the hidden portion 14. The hinge assembly 8 is hidden in the hidden portion 14, which improves the aesthetics of the overall design, makes the appearance of the product look more concise and high-end, provides the product with a neater and more beautiful appearance, and has a stronger integrity.

[0077] And, concealing components helps reduce the chance of dust and dirt entering the hinge area, which helps increase the life of the hinge components and reduces maintenance requirements.

[0078] Furthermore, the hidden hinge assembly can prevent the hinge point from becoming a dangerous part that may injure the user's fingers, thereby improving the safety of product use.

[0079] Furthermore, by designing the hinge assembly in a hidden portion, it is possible to make better use of the internal space, thereby maximizing the functionality of the device within a limited form factor.

[0080] like Figures 1 to 14As shown, the hinge assembly 8 of this embodiment includes a crank arm connector 81 and a pin 82, the hidden portion 14 includes a hidden hole 141 provided on the top of the housing 12 and a flip cover recess 142 provided on the bottom of the flip cover 13, the bottom of the crank arm connector 81 is provided in the hidden hole 141, the top of the crank arm connector 81 is provided in the flip cover recess 142, the pin 82 is assembled in the flip cover recess 142, and is rotatably connected to the top of the crank arm connector 81;

[0081] Specifically, the crank arm connector is a part shaped like a crank, usually with a bent or zigzag shape, used for the conversion of connecting actions. In this design, its bottom is installed in the hidden hole 141 of the shell 12, and the top is installed in the flip cover recess 142 of the flip cover 13, and the pin 82 is used as an axis-like part to connect or fix the two parts, allowing them to rotate or turn therebetween.

[0082] Specifically, the hidden hole 141 is located at the top of the shell 12, providing an installation position for the bottom of the crank arm connector 81, with the purpose of embedding part of the components to achieve the purpose of hiding, and the flip cover recess 142 is arranged at the bottom of the flip cover 13, providing an assembly position for the top of the crank arm connector 81 and the pin 82, ensuring the normal operation of the hinged assembly while maintaining the concealment of the assembly.

[0083] When the user needs to open or close the flip cover 13, the flip cover 13 rotates on the crank arm connector 81 through the pin 82, and its rotation base point is at the pin 82. The pin 82 is rotatably connected to the top of the crank arm connector 81 and installed in the flip cover recess 142. This design allows the flip cover 13 to rotate about a predetermined axis, that is, the flip cover 13 will rotate on the crank arm connector 81 through the flip cover recess 142 and the pin 82, and during the rotation process, the flip cover 13 can avoid the crank arm connector 81 through the flip cover recess 142. All connectors are well hidden in the hidden hole 141 and the flip cover recess 142, providing a clean and tidy appearance. This hidden hinge method improves the aesthetics of the product and may make it difficult for users to touch the hinged parts during use, reducing the risk of accidental injury.

[0084] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
