Description

Technical Field

[0001] This application relates to the technical field of plunger pumps, and more particularly to an emulsion pump and a container for holding emulsions. Background Technology

[0002] A lotion pump is a widely used dispensing device in cosmetics, skincare, and personal care products. It is primarily used to stably and controllably deliver viscous liquids such as lotions, serums, and cleansers stored in bottles to the outside of the container via manual pressing. Its basic structure typically includes a pressing head, pump body, piston, return spring, straw, dispensing nozzle, and multiple one-way valves (such as inlet and outlet valves). During operation, when the user presses down, the piston inside the pump body moves downward, compressing the liquid or air in the pump chamber, opening the outlet valve, and discharging the liquid through the outlet channel. When the pressing head is released, the spring pushes the piston back to its original position, creating negative pressure in the pump chamber, opening the inlet valve, and drawing liquid from the bottle into the pump chamber through the straw, completing one pumping cycle. Lotion pumps offer advantages such as good sealing, uniform dispensing, backflow prevention, and ease of use, making them a key component in modern liquid packaging for achieving precise dispensing and extending product shelf life.

[0003] As skincare product formulations become increasingly complex, some products require the separate storage of two chemically incompatible or unstable active ingredients to prevent reactions, degradation, or inactivation during long-term storage. This has led to the development of dual-chamber lotion bottles. These bottles feature two independent reservoirs, each holding different lotion components, such as aqueous and oil phases, active ingredients and base emulsions, vitamin C and metal catalysts, etc. The two chambers are connected to the same pump body structure via independent pipettes or channels, typically employing a dual-channel pump head or an integrated dual-path delivery system. During use, the two lotions can be pumped out simultaneously and merge at the pump head outlet or enter the mixing chamber for initial mixing, thus achieving immediate ingredient activation or uniform proportioning upon application. This design effectively solves the storage stability challenges of multi-component formulations, enhancing product efficacy and user experience.

[0004] However, existing dual-chamber emulsion bottles still have significant technical shortcomings, particularly in balancing mixing functionality with long-term sealing. While some dual-chamber emulsion bottles offer mixing capabilities, their structural design makes it difficult to ensure effective isolation between the two emulsions before first use. For example, some mixing pump heads have a shared mixing chamber or connecting channel internally. Even with a sealed structure, there is a risk of micro-gaps or material penetration, potentially leading to trace migration, gas exchange, or cross-contamination between the two emulsions during long-term storage. This premature contact can trigger slow chemical reactions, degradation of active ingredients, or microbial growth, affecting product stability and sensory quality, ultimately shortening the actual shelf life. Therefore, current technology cannot guarantee effective mixing during use while simultaneously ensuring complete isolation between the two emulsions before first use, limiting its application in high-activity, long-shelf-life products. Utility Model Content

[0005] This application provides an emulsion pump and a container for holding emulsions to solve the technical problem that existing dual-chamber emulsion bottles cannot effectively isolate two emulsions before first use, and cause the two emulsions to undergo micro-migration, gas exchange, or cross-contamination in advance. The technical solution is as follows:

[0006] In a first aspect, this application provides an emulsion pump, comprising: a plunger pump assembly having an inlet port for discharging emulsion into the plunger pump assembly; a storage tube sleeved on the end of the plunger pump assembly having the inlet port, the storage tube having a first storage chamber for storing a first target emulsion and a first delivery channel communicating with the inlet port, and an outlet and a first inlet on the end of the storage tube opposite to the plunger pump assembly, the outlet communicating with the first storage chamber and the first inlet communicating with the first delivery channel; and a stopper assembly having a plug and a baffle, the plug being fixed in the first delivery channel by insertion and removal through the first inlet, and the baffle being supported on the outer wall of the first storage chamber to be fastened and sealed to the outlet.

[0007] In one embodiment, the plunger pump assembly includes: a liquid storage silo with a constricted structure to form a second liquid storage chamber and a first valve chamber inside the liquid storage silo; a liquid storage pipe fitting sleeved on the outer wall of the first valve chamber to allow the first valve chamber to connect to a first delivery channel through an inlet port; and a movable rod with a straight rod structure, which passes through the first delivery channel, the first valve chamber, and the second liquid storage chamber. The movable rod has a first end and a second end, the first end being located in the second liquid storage chamber, and the second end being located in the first delivery channel and supported on the plug portion of the stopper component. The movable rod is also provided with an annular baffle located between the first end and the second end, and the annular baffle is supported on the inner wall of the first valve chamber.

[0008] In one embodiment, the device further includes: an infusion tube configured in an L-shape, the infusion tube penetrating the side wall of the reservoir fitting to connect to a first infusion channel, a second infusion channel and a second valve chamber within the infusion tube, the second infusion channel connecting to the first infusion channel through the second valve chamber, and the second infusion channel extending toward the reservoir fitting toward the plunger pump assembly; and a spherical component slidably disposed in the second valve chamber for controlling the opening and closing of the infusion tube within the second valve chamber.

[0009] In one embodiment, the plunger pump assembly further includes: a sleeve component, embedded in a liquid storage silo, located at one end of the liquid storage silo opposite to the liquid storage pipe; a central pipe component, slidably inserted in the sleeve component, the central pipe component having a third end and a fourth end; the third end extending into a second liquid storage cavity, and having a second inlet communicating with the second liquid storage cavity on the third end, and having an outlet port for discharging emulsion from the plunger pump assembly on the fourth end; and a flexible piston, sleeved on the central pipe component, located in the second liquid storage cavity, and the flexible piston being interference-fitted against the inner wall of the liquid storage silo.

[0010] In one embodiment, it further includes: a nozzle, disposed on the fourth end of the central tube, and the nozzle is connected to the liquid outlet port, the nozzle being used to guide the liquid outlet direction of the plunger pump assembly.

[0011] In one embodiment, the plunger pump assembly further includes an elastic element sleeved on the central tube, the elastic element being elastically supported between the central tube and the sleeve assembly.

[0012] In one embodiment, the elastic element is configured as a pressure spring made of plastic material.

[0013] In one embodiment, the movable rod is made of plastic.

[0014] In one embodiment, the plunger pump assembly further includes a capping component connected to the outer wall of the sleeve component, the inner wall of the capping component having a threaded structure for tightening onto the top of the bottle.

[0015] Secondly, embodiments of this application provide a container for holding emulsion, comprising: a bottle body having an opening at the top and a receiving chamber for storing a second target emulsion; and an emulsion pump as described above, the emulsion pump being threadedly mounted on the bottle body for extracting emulsion from the receiving chamber.

[0016] Compared to existing technologies, the emulsion pump and emulsion container proposed in the above technical solution ensure effective isolation of the first target emulsion from other emulsions before first use through a liquid storage tube and a stopper component. Specifically, the stopper is fixed in the first infusion channel by insertion and removal, effectively preventing trace migration, gas exchange, or cross-contamination between the first target emulsion in the liquid storage tube and the second target emulsion in the emulsion container, thereby greatly improving the product's storage stability and shelf life. The stopper component is only removed from the first infusion channel upon first use, allowing the first target emulsion stored in the first liquid storage chamber to flow out and mix with the second target emulsion in the emulsion container. This not only ensures that the two emulsions do not undergo unnecessary chemical reactions or degradation during long-term storage, but also maintains their original efficacy and active ingredients.

[0017] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

[0037] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0038] First Embodiment

[0039] Reference Figure 1 and Figure 2 As shown, an embodiment of this application proposes an emulsion pump, which may include: a plunger pump assembly 1, having an inlet port 133 for discharging emulsion into the plunger pump assembly 1; a storage tube 2, sleeved on the end of the plunger pump assembly 1 having the inlet port 133, the storage tube 2 having a first storage chamber 21 for storing a first target emulsion and a first delivery channel 22 communicating with the inlet port 133, and an outlet port 23 and a first inlet port 24 on the end of the storage tube 2 away from the plunger pump assembly 1, the outlet port 23 communicating with the first storage chamber 21 and the first inlet port 24 communicating with the first delivery channel 22; and a stopper assembly 3, having a plug part 31 and a baffle part 32, the plug part 31 being fixed in the first delivery channel 22 by insertion and removal through the first inlet port 24, and the baffle part 32 being supported on the outer wall of the first storage chamber 21 to be fastened and sealed to the outlet port 23.

[0040] Specifically, in the technical solution adopted in this application, the plunger pump assembly 1 has an extraction function for extracting emulsion, thereby providing an inlet port 133 and an outlet port 122 on the plunger pump assembly 1. The inlet port 133 is used to extend into the target container to extract the emulsion stored in the target container into the plunger pump assembly 1, while the outlet port 122 is used to spray out the emulsion in the plunger pump assembly 1 to achieve the extraction of emulsion in the target container. The key technical point of this application is that a liquid storage tube 2 is configured on the plunger pump assembly 1. The liquid storage tube 2 has two chambers located in the outer layer and the inner layer, which are used to store the first target emulsion and connect to the inlet port 133, respectively. The chamber located in the outer layer can be defined as the first liquid storage chamber 21, and the chamber located in the inner layer is positioned as the first delivery channel 22. Furthermore, two ports are provided at the end of the liquid storage tube 2 away from the plunger pump assembly 1, namely the outlet port 23 connecting to the first liquid storage chamber 21 and the first inlet port 24 connecting to the first delivery channel 22. The first target emulsion stored in the first liquid storage chamber 21 can flow out through the outlet port 23, while the inlet port 133 of the plunger pump assembly 1 can extend to the bottom of the target container through the first delivery channel 22 and extract the emulsion in the target container through the first inlet port 24. The emulsion pump of this application also includes a stopper component 3 disposed on the liquid storage tube 2. The stopper component 3 has a blocking part 31 and a baffle part 32. The blocking part 31 is inserted into the first liquid delivery channel 22 through the first liquid inlet 24 to block the first liquid delivery channel 22. At the same time, the baffle part 32 can be supported on the outer wall of the first liquid storage cavity 21, i.e. the outer wall of the liquid storage tube 2, in an overlapping manner, thereby sealing the liquid outlet 23 through the baffle part 32 to prevent the first target emulsion from flowing out of the first liquid storage cavity 21 before the first use. During use, the emulsion pump of this application can be configured on the target container. When used for the first time, the bottle stopper 3 is pulled out in the first infusion channel 22 to expose the outlet 23 and the first inlet 24 inside the target container, so that the first target emulsion stored in the first reservoir 21 flows out and mixes with the emulsion stored in the target container. The plunger pump assembly 1 can then extract the emulsion in the target container through the first infusion channel 22. Specifically, the emulsion enters the first infusion channel 22 through the first inlet 24 and is then extracted from the first infusion channel 22 through the inlet port 133 of the plunger pump assembly 1.

[0041] Furthermore, refer to Figure 3As shown, in some embodiments, the plunger pump assembly 1 includes: a liquid storage silo 13 with a constricted structure to form a second liquid storage chamber 131 and a first valve chamber 132 inside the liquid storage silo 13; a liquid storage pipe 2 sleeved on the outer wall of the first valve chamber 132 so that the first valve chamber 132 is connected to the first delivery channel 22 through the liquid inlet port 133; and a movable rod 14 with a straight rod structure, which passes through the first delivery channel 22, the first valve chamber 132, and the second liquid storage chamber 131. The movable rod 14 has a first end and a second end. The first end is located in the second liquid storage chamber 131, and the second end is located in the first delivery channel 22 and supported on the plug portion 31 of the stopper component 3. The movable rod 14 is also provided with an annular baffle 141 located between the first end and the second end, and the annular baffle 141 is supported on the inner wall of the first valve chamber 132.

[0042] Specifically, in the technical solution adopted in this application, in order to form a unidirectional flow channel in the plunger pump assembly 1, the plunger pump assembly 1 may include: a liquid storage silo 13 and a movable rod 14. The liquid storage silo 13 is configured as a tapering structure that gradually narrows towards the liquid storage tube 2, so that a second liquid storage chamber 131 and a first valve chamber 132 for storing emulsion are formed inside the liquid storage silo 13. The liquid storage tube 2 is fixed on the liquid storage silo 13 in a sleeve manner, specifically on the outer wall corresponding to the first valve chamber 132, so that the second liquid storage chamber 131, the first valve chamber 132 and the first delivery channel 22 are connected sequentially from top to bottom. The movable rod 14 is connected to the second liquid storage chamber 131, the first valve chamber 132, and the first infusion channel 22. The movable rod 14 has a first end and a second end. The first end is located in the second liquid storage chamber 131, and the second end is located in the first infusion channel 22 and abuts against the bottle stopper component 3 supported in the first infusion channel 22. Specifically, it is supported on the blocking part 31 of the bottle stopper component 3. An annular baffle 141 is also provided on the movable rod 14 between the first end and the second end, and the annular baffle 141 is supported on the inner wall of the first valve chamber 132. In use, the plunger pump assembly 1 can be activated by pressing. The pressing force is applied to the first end of the movable rod 14, causing the movable rod 14 to move and push against the bottle stopper component 3 through the first inlet 24 and out of the first delivery channel 22. At the same time, the baffle part 32 of the bottle stopper component 3 also releases the seal on the outlet 23. Thus, when the plunger pump assembly 1 is pressed for the first time, the first target emulsion stored in the first storage chamber 21 flows out through the storage pipe to mix with the emulsion in the target container. The first delivery channel 22, which is not blocked by the blockage part 31, can extract the mixed emulsion. It should be further explained that, due to the constricted structure inside the liquid storage silo 13, the annular baffle 141 moves with the piston rod and can be tightly supported on the inner wall of the first valve chamber 132 to seal the first valve chamber 132. This prevents the medium in the second liquid storage chamber 131 from flowing out through the inlet port 133, allowing the medium in the second liquid storage chamber 131 to be discharged from the plunger pump assembly 1 through the outlet port 122. When the plunger pump assembly 1 returns to its original position, it draws the medium in the second liquid storage chamber 131 to form a negative pressure environment, driving the movable rod 14 to move towards the second liquid storage chamber 131. The annular baffle 141 then releases its tight support from the inner wall of the first valve chamber 132, thereby drawing the emulsion through the first delivery channel 22 and sequentially discharging it into the second liquid storage chamber 131 through the first delivery channel 22 and the first valve chamber 132. The emulsion in the first valve chamber 132 flows into the second liquid storage chamber 131 through the gap between the annular baffle 141 and the inner wall of the first valve chamber 132. The medium in the second liquid storage chamber 131 can be air or emulsion.

[0043] Furthermore, refer to Figure 1 and Figure 3As shown, in some embodiments, it further includes: an infusion tube 4, configured as an L-shaped structure, the infusion tube 4 penetrating through the side wall of the reservoir fitting 2 to connect to the first infusion channel 22, the infusion tube 4 having a second infusion channel 41 and a second valve chamber 42, the second infusion channel 41 connecting to the first infusion channel 22 through the second valve chamber 42, and the second infusion channel 41 extending toward the reservoir fitting 2 in a direction close to the plunger pump assembly 1; and a spherical component 5, slidably disposed in the second valve chamber 42, for controlling the opening and closing of the infusion tube 4 in the second valve chamber 42.

[0044] Specifically, in the technical solution adopted in this application, in order to enable the emulsion pump to have a reverse spray function, that is, to be able to spray emulsion normally even after the emulsion pump is flipped, an independent infusion pipe 4 can be configured on the liquid storage pipe 2. The infusion pipe 4 has an L-shaped structure and runs through the structure of the liquid storage pipe 2 and communicates with the first infusion channel 22. The interior of the L-shaped infusion pipe 4 forms a second infusion channel 41 and a second valve chamber 42. The second infusion channel 41 is connected to the first infusion channel 22 through the second valve chamber 42, and the second infusion channel 41 extends towards the liquid storage pipe 2 in the direction close to the plunger pump assembly 1, located on one side of the liquid storage silo 13. After the emulsion pump is installed through the top opening of the target container, even if the product is inverted, the emulsion flowing to the top of the target container can still be inserted through the infusion pipe 4. A spherical component 5 is disposed in the second valve chamber 42, and the second valve chamber 42 is configured as a flared structure that gradually increases in size away from the second infusion channel 41. This forms a one-way valve in the infusion tube 4 through the spherical component 5 and the second valve chamber 42. In this embodiment, the spherical component 5 is preferably made of plastic. During use, when emulsion is drawn into the first infusion channel 22 through the second infusion channel 41, the emulsion pushes the spherical component 5 to move within the second valve chamber 42 until a gap appears between the spherical component 5 and the inner wall of the second valve chamber 42, through which the emulsion flows into the first infusion channel 22. Conversely, when emulsion in the first infusion channel 22 flows into the second valve chamber 42, the emulsion also pushes the spherical component 5 to move within the second valve chamber 42 until the gap between the spherical component 5 and the inner wall of the second valve chamber 42 is filled by the spherical component 5, thereby sealing the second valve chamber 42 and preventing the emulsion in the first infusion channel 22 from being discharged through the second infusion channel 41.

[0045] It needs to be further explained that when the emulsion pump of this application is used upside down, since there is emulsion remaining in the first infusion channel 22, the medium in the first infusion channel 22 is not a gaseous medium. When the emulsion is continuously replenished to the first infusion channel 22 through the infusion tube 4 in this embodiment, it is possible to achieve the effect of spraying emulsion when the emulsion pump is used upside down, while also sealing the first infusion channel 22 with emulsion to prevent a large amount of gaseous medium from entering.

[0046] Furthermore, refer to Figure 3 As shown, in some embodiments, the plunger pump assembly 1 further includes: a sleeve component 11, embedded in the liquid storage silo 13, located at one end of the liquid storage silo 13 away from the liquid storage pipe 2; a central pipe 12, slidably inserted in the sleeve component 11, the central pipe 12 having a third end and a fourth end; the third end extending into the second liquid storage chamber 131, and having a second inlet 121 communicating with the second liquid storage chamber 131 on the third end, and having an outlet port 122 for discharging emulsion from the plunger pump assembly 1 on the fourth end; and a flexible piston 15, sleeved on the central pipe 12, located in the second liquid storage chamber 131, and the flexible piston 15 being interference-fitted and supported on the inner wall of the liquid storage silo 13.

[0047] Specifically, in the technical solution adopted in this application, in order to compress or draw the medium in the second liquid storage chamber 131, the plunger pump assembly 1 may further include: a sleeve component 11, a central tube 12, and a flexible piston 15. Further, the sleeve component 11 is fixed in the liquid storage silo 13 in an embedded manner; and the central tube 12, by passing through the sleeve component 11, can serve as a piston rod capable of piston movement in the liquid storage silo 13. In this embodiment, the two ends of the central tube 12 can be defined as the third end and the fourth end. The third end extends into the second liquid storage chamber 131 and has a second inlet 121, while the fourth end has the aforementioned outlet 122. A flexible piston 15 is sleeved on the central tube 12, located on the third end in the second liquid storage chamber 131, and the flexible piston 15 is supported on the inner wall of the liquid storage silo 13 corresponding to the second liquid storage chamber 131 by an interference fit. In use, pressure is applied to the central tube 12 to drive it to move like a piston through the sleeve component 11 in the second liquid storage chamber 131. When the flexible piston 15 compresses the medium in the second liquid storage chamber 131, the annular baffle 141 on the movable rod 14 closes the first valve chamber 132, allowing the medium in the second liquid storage chamber 131 to enter the second inlet 121 and be discharged through the outlet port 122. Conversely, when the flexible piston 15 pulls the medium in the second liquid storage chamber 131, it can drive the annular baffle 141 on the movable rod 14 to open the first valve chamber 132, thereby extracting the emulsion in the first infusion channel 22 into the second liquid storage chamber 131.

[0048] In some embodiments, the central tube 12 has a built-in check valve, allowing the medium in the second reservoir 131 to enter through the second inlet 121, pass through the check valve, and exit through the outlet port 122. The check valve in the central tube 12 prevents the medium from flowing back from the outlet port 122 to the second outlet chamber 131. This ensures that when the flexible piston 15 compresses the medium in the second reservoir 131, the medium in the second reservoir 131 is discharged through the central tube. Conversely, when the flexible piston 15 pulls the medium in the second reservoir 131, creating a negative pressure environment, emulsion can be delivered to the second reservoir 131 through the first delivery channel 22. It should be noted that arranging a check valve on the central tube 12 is prior art in the field of emulsion pump technology, and therefore the principle will not be described in more detail.

[0049] Furthermore, refer to Figure 1 As shown, in some embodiments, it further includes: a nozzle, disposed on the fourth end of the central tube 12, and the nozzle is connected to the liquid outlet port 122, the nozzle being used to guide the liquid outlet direction of the plunger pump assembly 1.

[0050] Specifically, in the technical solution adopted in this application, a nozzle can be configured on the end of the plunger pump assembly 1 with the liquid outlet port 122. The nozzle can not only replace the central tube 12 to bear the pressing pressure, so as to avoid blocking the liquid outlet port 122 when pressing the central tube, but also guide the liquid outlet direction to be more convenient for receiving the emulsion.

[0051] Furthermore, refer to Figure 3 As shown, in some embodiments, the plunger pump assembly 1 further includes an elastic element 16, which is sleeved on the central tube 12 and elastically supported between the central tube 12 and the sleeve assembly 11.

[0052] Specifically, in the technical solution adopted in this application, in order to achieve automatic return of the central tube 12 after pressing, an elastic element 16 can be sleeved on the central tube 12, and the elastic element 16 is elastically supported between the central tube 12 and the sleeve component 11. In use, pressing the central tube 12 causes the soft piston 15 to move in the second liquid storage chamber 131. At this time, the elastic element 16 stores elastic energy. After releasing the pressing force on the central tube 12, the elastic element 16 releases the stored elastic energy to drive the central tube 12 back to its initial position, and the soft piston 15 completes one piston movement in the second liquid storage chamber 131.

[0053] Furthermore, in some embodiments, the elastic element 16 is configured as a compression spring made of plastic material. The movable rod 14 is also made of plastic.

[0054] Specifically, in the technical solution adopted in this application, the elastic element 16 can be a pressure spring, while the movable rod 14 replaces the ball in the one-way ball valve, and the movable rod 14 can remove the bottle stopper component 3 in the first infusion channel 22 by pushing it out. In this embodiment, both the movable rod 14 and the pressure spring are made of plastic, so that the overall structure of the emulsion pump in this application is made of plastic, thereby avoiding contamination of the emulsion pump by impurities such as rust, improving the reuse rate, and making it more environmentally friendly.

[0055] Furthermore, refer to Figure 3 As shown, in some embodiments, the plunger pump assembly 1 further includes a capping component 17 connected to the outer wall of the sleeve component 11, and the inner wall of the capping component 17 is provided with a threaded structure for tightening onto the top of the bottle body 7.

[0056] Specifically, in the technical solution adopted in this application, the emulsion pump can be detachably installed on the container by means of the capping component 17. Specifically, the capping component 17 is sleeved on the top of the container and screwed into the threaded structure on the top of the container by means of the threaded structure on the capping component 17. The liquid storage tank 13 and the liquid storage tube 2 are placed inside the container to facilitate the extraction of emulsion from the container, while the nozzle and part of the central tube are placed outside the container to facilitate pressing.

[0057] Second Embodiment

[0058] Reference Figure 4 As shown, an embodiment of this application also proposes a container for holding emulsion, which may include: a bottle body 7 having an opening at the top and a receiving chamber 70 for storing a second target emulsion; and an emulsion pump as described in the first embodiment above, which is threadedly mounted on the bottle body 7 for extracting emulsion from the receiving chamber 70.

[0059] Specifically, the technical solution adopted in this application also protects a container for holding emulsions, which may include: a bottle body 7 and an emulsion pump disposed at the top opening of the bottle body 7. The specific structure of the emulsion pump can be referred to the content of the first embodiment described above. The receiving chamber 70 of the bottle body 7 is used to store the second target emulsion. When the bottle stopper 3 opens the first liquid storage chamber 21, the first target emulsion flows out through the liquid outlet 23, thus mixing the first target emulsion with the second target emulsion. By using the emulsion pump or the container for holding emulsions of this application, the mixing time of the two emulsions can be delayed, and the shelf life of the mixed emulsion is extended by comparison, thereby improving the quality of the mixed emulsion.
