Description

Technical Field

[0001] This application relates to the field of packaging technology, and more particularly to a vacuum press bottle. Background Technology

[0002] In recent years, the main growth drivers in the cosmetics market have come from skincare and makeup products. Vacuum-sealed bottles, due to their advantages such as anti-oxidation, anti-pollution, and non-backflow, are widely used in various skincare products, especially those that help treat sensitive skin, acne-prone skin, and other skin problems. These products are typically packaged in vacuum bottles to fundamentally prevent product contamination and maintain the product's activity.

[0003] However, in existing technologies, most vacuum pump bottles use an up-and-down pressing motion and mostly rely on a movable pump core to dispense the contents. On the one hand, the up-and-down pressing design is not conducive to handheld use of vacuum pump bottles, limiting their application to skincare products such as facial cleansers, hand creams, and lotions. Skincare products like lip masks, which require direct hand application to the skin, as well as makeup products such as lipsticks and eyebrow pencils, cannot use this type of packaging, resulting in significant product limitations. On the other hand, the use of a movable pump core undoubtedly increases the structural complexity of the vacuum pump bottle, leading to higher product costs and less portability.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Utility Model Content

[0005] The purpose of this application is to provide a vacuum press bottle that eliminates moving parts such as pump cores, making the product structure simpler and lighter, and allowing users to use it by hand, thus expanding its application range and reducing product limitations.

[0006] The technical solution provided in this application is as follows:

[0007] A vacuum press bottle, comprising:

[0008] Bottle body;

[0009] The bottle body is provided with a first chamber and a second chamber. The first chamber is suitable for containing the material, and the second chamber is provided with a three-way pipe.

[0010] The three-way tube has a first port, a second port and a third port, wherein the first port is connected to the first chamber, the second port is connected to the outside of the bottle body, and the first port is provided with a first one-way valve, the second port is provided with a second one-way valve, and the bottle body is provided with a pressing component corresponding to the third port.

[0011] The pressing component can be selectively in an initial state and a pressing state. In the initial state, the material in the first chamber enters the three-way tube through the first one-way valve; in the pressing state, the material in the three-way tube is discharged to the outside of the bottle through the second one-way valve.

[0012] In some embodiments, the first chamber and the second chamber are arranged sequentially along the length of the bottle body; and

[0013] The first and second ports are located at both ends of the three-way pipe along its length, the third port is located on the side wall of the three-way pipe, and the side wall of the second chamber is provided with a mounting hole corresponding to the position of the third port for mounting the pressing assembly.

[0014] In some embodiments, the tee pipe includes a first pipe section, a second pipe section, and a third pipe section connected in sequence along its own length direction. The first pipe section is provided with a first pipe opening at the end away from the second pipe section, the third pipe section is provided with a second pipe opening at the end away from the second pipe section, and the second pipe section is provided with a third pipe opening on its side wall.

[0015] Wherein, the diameter of the first pipe section and the diameter of the third pipe section are both greater than the diameter of the second pipe section, and the diameter of the first pipe opening and the diameter of the second pipe opening are both smaller than the diameter of the third pipe opening.

[0016] In some embodiments, the pressing assembly includes a bracket and a pressing element;

[0017] The bracket is provided with a through hole, and the pressing member is movably inserted through the through hole; and

[0018] The second chamber has a mounting hole on its side wall, and the bracket is fixed in the mounting hole to allow the pressing member to be movably mounted at the third port.

[0019] In the initial state, the end face of the pressing member away from the third port is flush with the outer wall of the bottle. From the initial state to the pressing state, the pressing member moves toward the third port to compress the gas in the three-way tube.

[0020] In some embodiments, the pressing member is provided with a piston, which is movably inserted into the third port, and the outer diameter of the piston matches the diameter of the third port.

[0021] In some embodiments, the outer wall of the tee pipe is provided with an installation station on the periphery of the third pipe opening for setting an elastic element. The end of the elastic element away from the installation station abuts against the end face of the pressing element facing the third pipe opening, which is suitable for resetting the pressing element from the pressed state to the initial state.

[0022] In some embodiments, the inner sidewall of the bracket is provided with a guide boss, the sidewall of the pressing member is provided with a guide groove, the guide boss is engaged in the guide groove, and the pressing member slides relative to the bracket along the length direction of the guide boss.

[0023] In some embodiments, the pressing assembly includes a pressing element and a deformable element;

[0024] The deformable member forms a third chamber with a first opening; the pressing member is sleeved on the end of the deformable member with the first opening, and the pressing member is movably inserted into the mounting hole; and the third port communicates with the third chamber.

[0025] In the initial state, the end face of the pressing member away from the deformable member is flush with the outer wall of the bottle. From the initial state to the pressing state, the pressing member moves toward the deformable member to compress the deformable member, reduce the volume of the third chamber, and thus compress the gas in the three-way tube.

[0026] In some embodiments, the bottle body includes a main bottle body and a secondary bottle body;

[0027] The main bottle contains the first chamber, and the first chamber has a second opening. The secondary bottle is capped at the second opening, and the secondary bottle contains the second chamber.

[0028] The second chamber has a third opening at the end away from the first chamber, and the side wall of the second chamber has a mounting hole, in which the pressing component is installed;

[0029] The first pipe opening is connected to the second opening, the second pipe opening passes through the third opening, and the third pipe opening is connected to the mounting hole.

[0030] In some embodiments, a pressure member is provided in the first chamber, and the sidewall of the pressure member abuts against the sidewall of the first chamber;

[0031] When the pressing assembly is in the pressing state to the initial state, the pressing member compresses the space in the first chamber used to contain the material, and the material in the first chamber enters the three-way pipe through the first one-way valve.

[0032] In some embodiments, the bottle body is provided with a discharge head corresponding to the second pipe opening, the discharge head is provided with a discharge port, and the material in the three-way pipe is adapted to be discharged to the outside of the bottle body through the second one-way valve and the discharge head.

[0033] In some embodiments, the vacuum press bottle further includes:

[0034] A cover body is provided on the discharge head.

[0035] In some embodiments, the end face of the cover facing the discharge head is provided with a sealing element, which is adapted to be inserted into the discharge port.

[0036] The technical advantages of this application are as follows:

[0037] 1. In this application, by setting up a three-way pipe and respectively installing a first one-way valve, a second one-way valve, and a pressing assembly at the three ports of the three-way pipe, the output of the material in the first chamber is realized. That is, when the pressing assembly is in the initial state, the air pressure in the three-way pipe is lower than the air pressure in the first chamber. At this time, the material in the first chamber can enter the three-way pipe through the first one-way valve. When the user presses the pressing assembly, causing the pressing assembly to enter the pressing state from the initial state, the gas in the three-way pipe is gradually compressed, making the air pressure in the three-way pipe higher than the air pressure in the first chamber and the air pressure outside the bottle. At this time, the material in the three-way pipe can be discharged to the outside of the bottle through the second one-way valve for the user to use. At the same time, since both the first one-way valve and the second one-way valve only support unidirectional flow of fluid, the material entering the three-way pipe from the first chamber will not flow back into the first chamber, and gas, dust, bacteria, etc. outside the bottle will not enter the three-way pipe through the second one-way valve, ensuring that the material in the bottle is not contaminated. Furthermore, compared to existing technologies, this application eliminates moving parts such as the pump core, resulting in a simpler, lighter, and lower-cost structure.

[0038] 2. In this application, the pressing component is located on the side wall of the bottle, making the vacuum pressing bottle provided by this application different from the side pressing structure of the prior art which involves pressing up and down. Thus, users can directly hold the vacuum pressing bottle provided by this application and press the pressing component on the bottle body with their thumb to dispense the product, directly applying the product inside the bottle to the skin. Therefore, the vacuum pressing bottle can be used not only as a packaging bottle for products such as facial cleanser, hand cream, and lotion, but also as a packaging bottle for products such as lip masks, lipsticks, and eyebrow pencils, with a wider range of applications, fewer product limitations, and the potential for mass production.

[0039] 3. In this application, the bottle body includes a main bottle body and a secondary bottle body. The main bottle body is mainly used to contain the agent, while the secondary bottle body is mainly used to install the pressing component and the three-way pipe to realize the agent delivery function. This application integrates the structure that realizes the agent delivery function into the secondary bottle body, which allows for the independent replacement of the main bottle body. Thus, when the agent in the bottle body is used up, the user can directly remove the main bottle body from the secondary bottle body and replace it with a new main bottle body, or refill the agent body into the removed main bottle body, and then assemble the main bottle body and the secondary bottle body for continued use, which is highly practical.

[0040] 4. In this application, a pressing component is also provided in the first chamber. When the pressing assembly enters the initial state from the pressing state, the pressing component moves along the side wall of the first chamber toward the first one-way valve to compress the space in the first chamber used to contain the agent. On the one hand, this ensures that all the agent in the first chamber can be used without residue, avoiding waste; on the other hand, it can concentrate the agent in the first chamber near the first one-way valve. Thus, when only a small amount of agent remains in the bottle, it will not require multiple presses before the agent is discharged from the bottle, improving the user's product experience.

[0059] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0061] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0062] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0063] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0064] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various devices of this application are relative rather than absolute. These descriptions are appropriate when the devices are in the positions shown in the drawings. If the description of the positions of the devices changes, these directional indications also change accordingly.

[0065] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0066] According to a specific embodiment provided in this application, see [link to specific embodiment]. Figure 1 and Figure 2 A vacuum-pressable bottle may include a bottle body, and the bottle body is provided with a first chamber 110 and a second chamber 210. The first chamber 110 is adapted to contain a substance, and the second chamber 210 is provided with a three-way pipe 300. Specifically, the three-way pipe 300 has a first port 311, a second port 331, and a third port 321. The first port 311 is connected to the first chamber 110, and the second port 331 is connected to the outside of the bottle body. The first port 311 is provided with a first one-way valve 312, and the second port 331 is provided with a second one-way valve 332. Furthermore, a pressing assembly 400 is provided on the bottle body corresponding to the third port 321.

[0067] The pressing component 400 can be selectively in an initial state and a pressed state. In the initial state, the material in the first chamber 110 enters the three-way tube 300 through the first one-way valve 312; in the pressed state, the material in the three-way tube 300 is discharged to the outside of the bottle through the second one-way valve 332.

[0068] This embodiment achieves the output of the material in the first chamber 110 by setting a three-way pipe 300 and respectively setting a first one-way valve 312, a second one-way valve 332, and a pressing assembly 400 at the three ports of the three-way pipe 300. Compared with the common method of pumping out the material using a pump core in the prior art, the vacuum pressing bottle provided in this embodiment has a simpler and lighter structure, lower manufacturing cost, and can be mass-produced.

[0069] Specifically, when the pressing component 400 is in its initial state, the air pressure inside the three-way tube 300 is lower than the air pressure inside the first chamber 110. At this time, the material in the first chamber 110 will enter the three-way tube 300 through the first one-way valve 312 due to the air pressure difference between the first chamber 110 and the three-way tube 300. When the user presses the pressing component 400, causing it to enter the pressing state from the initial state, the gas inside the three-way tube 300 is gradually compressed, making the air pressure inside the three-way tube 300 higher than the air pressure inside the first chamber 110 and the air pressure outside the bottle. At this time, the material inside the three-way tube 300 can be discharged to the outside of the bottle through the second one-way valve 332 for the user to use. Meanwhile, since both the first one-way valve 312 and the second one-way valve 332 only support unidirectional flow of fluid, the material entering the three-way pipe 300 from the first chamber 110 will not flow back into the first chamber 110. In addition, gases, dust, bacteria, etc. outside the bottle will not enter the three-way pipe 300 through the second one-way valve 332, which can ensure that the material inside the bottle is not contaminated and has strong practicality.

[0070] Further, see Figure 2 The first chamber 110 and the second chamber 210 are arranged sequentially along the length of the bottle. At this time, the length of the three-way tube 300 is roughly aligned with the length of the bottle, and the first port 311 connecting to the first chamber 110 and the second port 331 connecting to the outside of the bottle are located at opposite ends of the three-way tube 300 along its length, while the third port 321 is located on the side wall of the three-way tube 300. Simultaneously, the side wall of the second chamber 210 has a mounting hole 211 corresponding to the position of the third port 321, for mounting the pressing assembly 400.

[0071] In this embodiment, by arranging the first chamber 110 and the second chamber 210 vertically along the length of the bottle and placing the pressing component 400 on the side wall of the bottle, the vacuum pressing bottle provided in this embodiment has a side-pressing structure, unlike the vertical pressing structure in the prior art. Thus, the user can directly hold the vacuum pressing bottle provided in this embodiment and press the pressing component 400 on the bottle body with their thumb to dispense the product, directly applying the product to the skin. Therefore, the vacuum pressing bottle can be used not only as a packaging bottle for products such as facial cleanser, hand cream, and lotion, but also as a packaging bottle for products such as lip masks, lipsticks, and eyebrow pencils, with a wider range of applications, fewer product limitations, and the potential for mass production.

[0072] Specifically, see Figure 2 and Figure 5 The tee pipe 300 includes a first pipe section 310, a second pipe section 320, and a third pipe section 330 connected sequentially along its length, and the first pipe section 310, the second pipe section 320, and the third pipe section 330 are integrally formed. At this time, the first pipe section 310 has the aforementioned first pipe opening 311 at the end away from the second pipe section 320, the third pipe section 330 has the aforementioned second pipe opening 331 at the end away from the second pipe section 320, and the second pipe section 320 has the aforementioned third pipe opening 321 on its side wall.

[0073] In this embodiment, the diameters of the first tube 310 and the third tube 330 are both larger than the diameter of the second tube 320. By reducing the diameter of the second tube 320 to be smaller than that of the first tube 310 and the third tube 330, the material in the three-way tube 300 can be transported from the first port 311 to the second port 331 in a shorter time, resulting in a faster discharge speed. Conversely, the length of the first tube 310 is smaller than that of the third tube 330, which allows more material in the three-way tube 300 to accumulate at the second port 331, further accelerating the discharge speed. Once the user presses the pressing component 400 on the side of the vacuum pressing bottle, the material in the three-way tube 300 can flow directly out through the second one-way valve 332, preventing situations where no material flows out after pressing or only flows out after multiple presses, effectively improving the user experience.

[0074] Furthermore, the diameter of the first port 311 and the diameter of the second port 331 are both smaller than the diameter of the third port 321.

[0075] Specifically, in all the above embodiments, a pressing component 400 is provided at the third port 321 on the bottle body. By pressing the pressing component 400, the gas inside the three-way tube 300 is compressed, creating a higher gas pressure inside the three-way tube 300. Similarly, when the user releases the pressing component 400, returning it to its initial state, the gas pressure inside the three-way tube 300 decreases, creating a lower gas pressure. It is understandable that all the above embodiments utilize the change in gas pressure inside the three-way tube 300 to achieve the delivery of the material inside the bottle. In this embodiment, by increasing the diameter of the third port 321 to be larger than that of the first port 311 and the second port 331, the volume of gas that the pressing component 400 can compress can be increased to a certain extent. This increases the pressure difference between the front and back of the three-way tube 300, which is more conducive to the delivery of the contents of the bottle. This allows more and faster contents of the first chamber 110 to enter the three-way tube 300, and the contents of the three-way tube 300 to be delivered to the outside of the bottle more quickly for the user to use. This makes it highly practical.

[0076] Specifically, see Figure 1 , Figure 2 and Figure 6 The pressing assembly 400 includes a bracket 410 and a pressing member 420. The bracket 410 has a through hole through which the pressing member 420 is movably inserted. Meanwhile, the second chamber 210 has a mounting hole 211 on its side wall. The bracket 410 is fixed in the mounting hole 211 to movably mount the pressing member 420 to the third port 321. When the pressing assembly 400 is in the initial state, the end face of the pressing member 420 away from the third port 321 is flush with the outer wall of the bottle. When the user presses the pressing member 420, changing the pressing assembly 400 from the initial state to the pressing state, the pressing member 420 moves toward the third port 321 to compress the gas in the three-way tube 300. When the user releases the pressing member 420, changing the pressing assembly 400 from the pressing state to the initial state, the pressing member 420 moves away from the third port 321. At this time, the gas pressure in the three-way tube 300 decreases.

[0077] Specifically, see Figure 2 and Figure 5 The outer wall of the tee pipe 300 has an installation station 322 around the third pipe opening 321 for installing an elastic element; and the end of the elastic element away from the installation station 322 abuts against the end face of the pressing element 420 facing the third pipe opening 321. When the user releases the pressing element 420, the elastic element can reset the pressing element 420 from the pressed state to the initial state.

[0078] The elastic element is preferably a spring, and there are at least two elastic elements evenly distributed around the third pipe opening 321, so that the pressing element 420 can be evenly stressed, and the structure is more reasonable. In this case, there can be one installation station 322, which is in a ring shape and surrounds the third pipe opening 321, and the elastic elements are all set on the installation station 322; or, in actual production, there are at least two installation stations 322, which are set one-to-one with the elastic elements. In this case, the installation stations 322 are in an arc shape and are arranged sequentially along the circumference of the third pipe opening 321, and each installation station 322 is provided with an elastic element. These are all within the protection scope of this application and will not be described in detail here.

[0079] Specifically, see Figure 2 and Figure 6 The inner wall of the bracket 410, away from the third port 321, has a first limiting boss 412, and the outer wall of the pressing member 420 has a second limiting boss 422. When the pressing assembly 400 is in its initial state, the side of the second limiting boss 422 away from the third port 321 abuts against the side of the first limiting boss 412 facing the third port 321, and the end of the elastic member away from the installation position 322 abuts against the side of the second limiting boss 422 near the third port 321. When the user presses the pressing member 420, the elastic member is compressed, and the second limiting boss 422 disengages from the first limiting boss 412.

[0080] This embodiment restricts the movement of the pressing member 420 by setting a first limiting boss 412 and a second limiting boss 422, preventing the pressing member 420 from detaching from the bracket 410 under the rebound of the elastic member, thereby improving the overall assembly degree of the vacuum pressing bottle.

[0081] Specifically, see Figure 2 and Figure 6 The pressing component 420 is provided with a piston 421, which is located on the side of the pressing component 420 facing the third pipe opening 321 and is movably inserted into the third pipe opening 321. The outer diameter of the piston 421 matches the diameter of the third pipe opening 321, ensuring the airtightness of the three-way pipe 300. This allows the user to move the piston 421 by pressing the component 400, thereby controlling the air pressure inside the three-way pipe 300.

[0082] As a preferred option, see Figure 2 The piston 421 has a groove on the side away from the pressing member 420, which can increase the volume of the material that the three-way pipe 300 can hold without increasing the radial dimension of the three-way pipe 300, and ensure that the three-way pipe 300 has good airtightness. The structure is reasonable and highly practical.

[0083] Further, see Figure 2 and Figure 7To improve the structural stability of the vacuum press bottle, in one specific embodiment, the end of the bracket 410 near the third port 321 abuts against the outer wall of the three-way tube 300. Simultaneously, a support member 213 is provided at the end of the side wall of the second chamber 210 away from the pressing assembly 400, and this support member 213 abuts against the side of the three-way tube 300 opposite to the pressing assembly 400. In this way, the three-way tube 300 can remain stable under the combined clamping action of the support member 213 and the bracket 410, and will not shake due to the movement of the pressing member 420 and the piston 421. The structure is reasonably designed and highly practical.

[0084] It is worth noting that in this embodiment, a gap should exist between the bracket 410 and the three-way tube 300 so that the gas in the second chamber 210 can flow with the gas between the pressing member 420 and the three-way tube 300, preventing a vacuum from forming between the pressing member 420 and the three-way tube 300 after being pressed, which would prevent it from returning to its initial state. See also... Figure 8 If there are at least two installation stations 322, the gap between two adjacent installation stations 322 can also be used for the flow of gas between the second chamber 210 and the pressing part 420 and the three-way pipe 300, which is highly practical.

[0085] Specifically, see Figure 6 The inner wall of the bracket 410 is provided with a guide boss 411, and the outer wall of the pressing member 420 is provided with a guide groove. When the pressing member 420 is inserted into the bracket 410, the guide boss 411 is engaged in the guide groove. In this way, the pressing member 420 can slide relative to the bracket 410 along the length direction of the guide boss 411, resulting in higher product structural stability and better operating feel.

[0086] Specifically, see Figure 6 The guide boss 411 has a guide surface 4111 at one end facing the third port 321, which can guide the guide boss 411 to pass through the guide groove, which is conducive to the rapid assembly between the bracket 410 and the pressing member 420.

[0087] In one specific embodiment, see Figure 10 The pressing assembly 400 includes a pressing member 420 and a deformable member 430. The deformable member 430 is supported by soft rubber and has a third chamber 431 with a first opening. The pressing member 420 is sleeved on the end of the deformable member 430 with the first opening and is movably inserted into the mounting hole 211. Simultaneously, a third port 321 connects to the third chamber 431.

[0088] In this embodiment, when the pressing member 420 is pressed, the pressing member 420 will squeeze the deformable member 430, causing the deformable member 430 to deform, thereby reducing the size of the third chamber 431 between the pressing member 420 and the deformable member 430, and thus compressing the gas in the three-way pipe 300.

[0089] Specifically, when the pressing assembly 400 is in the initial state, the end face of the pressing member 420 away from the deformable member 430 is flush with the outer wall of the bottle; when the pressing assembly 400 is in the initial state to the pressing state, the pressing member 420 moves toward the deformable member 430 to compress the deformable member 430, reduce the volume of the third chamber 431, and thus compress the gas in the three-way tube 300.

[0090] In one specific embodiment, see Figure 2 The first chamber 110 is provided with a pressure member 112, and the side wall of the pressure member 112 abuts against the side wall of the first chamber 110. When the pressing assembly 400 changes from the pressing state to the initial state, the pressure member 112 compresses the space in the first chamber 110 used to contain the material, and the material in the first chamber 110 enters the three-way pipe 300 through the first one-way valve 312.

[0091] Specifically, in this embodiment, when the pressing component 400 resets from the pressed state to the initial state, the pressing member 112 moves along the side wall of the first chamber 110 toward the first one-way valve 312, thereby compressing the space in the first chamber 110 used to contain the agent. On the one hand, this ensures that all the agent in the first chamber 110 can be used without residue, avoiding waste; on the other hand, it allows the agent in the first chamber 110 to be concentrated near the first one-way valve 312. Thus, when only a small amount of agent remains in the bottle, it avoids the situation where multiple presses are required before the agent is discharged from the bottle, improving the user's product experience.

[0092] Specifically, see Figure 2 and Figure 3 The pressure member 112 includes a main board 1121 and a side plate 1122 surrounding the main board 1121, with the side plate 1122 extending towards the main board 1121 on the side away from the first one-way valve 312. At this time, the pressure member 112 divides the space of the first chamber 110 into two parts: the space on the side of the pressure member 112 away from the first one-way valve 312 is used to contain gas, and the space on the side of the pressure member 112 facing the first one-way valve 312 is used to contain the feed material. When the feed material in the first chamber 110 decreases, the gas on the side of the pressure member 112 away from the first one-way valve 312 can diffuse, increasing its volume ratio, thereby causing the pressure member 112 to move towards the first one-way valve 312.

[0093] In addition, see Figure 3The side plate 1122 has a recessed groove on the side that abuts against the side wall of the first chamber 110. This reduces the contact area between the side plate 1122 and the side wall of the first chamber 110, reducing friction and improving the smoothness of the movement of the pressure member 112. Since both ends of the side plate 1122 along the length of the bottle still abut against the side wall of the first chamber 110, it provides good leak-proof protection, preventing the material from leaking from the side of the pressure member 112 facing the first one-way valve 312 into the space on the side of the pressure member 112 away from the first one-way valve 312 during the movement of the pressure member 112. Simultaneously, it also prevents gas in the space on the side of the pressure member 112 away from the first one-way valve 312 from entering the space on the side of the pressure member 112 facing the first one-way valve 312, thus avoiding material contamination.

[0094] In one specific embodiment, see Figure 2 and Figure 4 The bottle body is provided with a discharge head 500 at the second pipe opening 331, and the discharge head 500 is provided with a discharge port 510. The material in the three-way pipe 300 is suitable for being discharged to the outside of the bottle body through the second one-way valve 332 and the discharge head 500.

[0095] Specifically, see Figure 4 The dispensing head 500 can be tongue-shaped, in which case the vacuum press bottle can be used to hold lipsticks, lip masks, or eye creams; or, the dispensing head 500 can be pen-tip shaped, in which case the vacuum press bottle can be used as the casing for products such as eyeliner pens or eyebrow pencils. Of course, in actual production, the dispensing head 500 can also have other structures, which are not limited here, and are all within the scope of protection of this application.

[0096] Specifically, see Figure 1 , Figure 2 , Figure 4 and Figure 8 The bottle body includes a main bottle body 100 and a secondary bottle body 200. The main bottle body 100 contains the aforementioned first chamber 110, and the first chamber 110 has a second opening 111. The secondary bottle body 200 is fitted over the second opening 111, and the secondary bottle body 200 contains the aforementioned second chamber 210. Furthermore, the end of the second chamber 210 away from the first chamber 110 has a third opening 212, and the side wall of the second chamber 210 has a mounting hole 211, in which the pressing assembly 400 is installed. A first port 311 communicates with the second opening 111, a second port 331 passes through the third opening 212, and a third port 321 communicates with the mounting hole 211.

[0097] In this embodiment, the bottle body includes a main bottle body 100 and a secondary bottle body 200. The main bottle body 100 is mainly used to contain the liquid, while the secondary bottle body 200 is mainly used to install the pressing component 400 and the three-way tube 300 to realize the function of liquid delivery. This embodiment integrates the structure that realizes the function of liquid delivery onto the secondary bottle body 200, which allows for the independent replacement of the main bottle body 100. Thus, when the liquid in the bottle is used up, the user can directly remove the main bottle body 100 from the secondary bottle body 200 and replace it with a new main bottle body 100, or refill the removed main bottle body 100 with liquid, and then reassemble the main bottle body 100 and the secondary bottle body 200 for continued use, making it highly practical.

[0098] The main bottle body 100 and the auxiliary bottle body 200 can be connected by screwing on threads or by snap-fitting. Further details are omitted here, as both are within the scope of protection of this application.

[0099] Specifically, see Figure 1 and Figure 9 The vacuum press bottle also includes a cap 600, which is placed over the dispensing head 500 to prevent external bacteria from entering the dispensing port 510 and contaminating the agent. It also prevents the agent in the dispensing head 500 from flowing out to the outside. Preferably, the cap 600 has a sealing element 610 on one end facing the dispensing head 500. This sealing element 610 is suitable for insertion into the dispensing port 510, providing a better sealing effect and further preventing the agent in the dispensing port 510 from being contaminated by external bacteria and preventing the agent from flowing out of the dispensing port 510. This design is highly practical.

[0100] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0101] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
