Description

Technical Field

[0001] This utility model relates to the field of dispenser technology, and in particular to a dispenser. Background Technology

[0002] As consumers pay increasing attention to product quality and experience, the cosmetics and food industries are also placing higher demands on product preservation and activity maintenance.

[0003] Currently, dual-compartment bottles are commonly used in the market to provide light protection or freshness preservation by adding an inner compartment, thus preventing the activity of active ingredients in the aerobic components from weakening and affecting the consumer experience. However, existing dual-compartment bottles cannot simultaneously ensure the airtightness of the compartments themselves, as well as the airtightness between the compartments and the bottle. Furthermore, they require specific pump cores to achieve mixing between the two compartments, resulting in higher costs.

[0004] Therefore, there is an urgent need for a distributor that can solve the above problems in order to improve the user experience. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems of poor sealing of existing dual-compartment bottles and high cost of using specific pump cores. This invention provides a dispenser with good sealing performance, which can achieve dual-material mixing using a universal pump core, thereby reducing costs and improving the user experience.

[0006] To solve the above-mentioned technical problems, this utility model discloses a dispenser, comprising: a first storage container extending along a first direction and having a first receiving cavity for storing a first product; a second storage container extending along the first direction and having a second receiving cavity for storing a second product different from the first product; a first end of the second storage container being sealed to the first end of the first storage container, the first end of the second storage container having a first insertion hole communicating with the second receiving cavity; a limiting member fixedly disposed at the first end of the second storage container; and a pump assembly comprising: a pump core assembly extending along the first direction, the pump core assembly being inserted into the second receiving cavity through the first insertion hole, and the pump core assembly being sealed to the first end of the second storage container along a second direction, the pump core assembly being configured to move relative to the first end of the second storage container and the limiting member along the first direction under the action of an external force, the first direction being perpendicular to the first end of the first storage container and the limiting member. The second direction intersects; a sealing piston, connected to the pump core assembly, is housed in the first receiving cavity, the sealing piston being used for a sealing connection with the second end of the second reservoir, the sealing piston being configured to move along the first direction under the drive of the pump core assembly; wherein, the dispenser is configured to include a first state, a second state, and a third state; in the first state, the pump core assembly is not pushed, and the first and second receiving cavities are separated by the sealing piston; in the second state, the pump core assembly is pushed, driving the sealing piston to move along the first direction, such that the sealing piston is spaced apart from the second reservoir, allowing the second product to enter the first receiving cavity and form a mixture with the first product; in the third state, the pump core assembly is further pushed until it connects with the limiting member to restrict the pump core assembly from driving the sealing piston to move along the first direction, and to activate the pump core assembly to dispense the mixture.

[0007] By adopting the above technical solution, on the one hand, the pump core assembly of this application embodiment is inserted into the second receiving cavity through the first insertion hole and is sealed to the first end of the second reservoir along the second direction (i.e., radially). Compared with the prior art sealing design that uses an additional sliding piston as a sealing element for the second reservoir (e.g., the inner chamber), the sealing design of this application embodiment, which directly seals the second reservoir by combining the pump core assembly with the second reservoir, has the advantages of simple structure, good sealing effect, and high stability. Furthermore, this application embodiment also uses upper and lower multiple sealing measures to form a complete closed-loop sealing system through the sealing connection between the sealing piston and the second reservoir, and the sealing connection between the first end of the second reservoir and the first end of the first reservoir, thereby improving the sealing effect of the second reservoir and the connection between the second reservoir and the first reservoir.

[0008] On the other hand, the embodiments of this application, through the limiting design between the limiting member and the pump core assembly, enable the consumer to press the dispenser of this application, causing the pump core assembly to move linearly downwards until it connects with the limiting member and reaches the limiting position. This drives the sealed piston connected to the pump core assembly to move downwards synchronously relative to the second end of the second reservoir, allowing the first product in the second reservoir to mix with the second product in the first reservoir. Therefore, there is no need to select a pump core assembly with a special fixed design (e.g., a pump inner ring with a threaded connection for limiting), and a common pump core assembly can be used to achieve dual-material mixing, thereby reducing costs and improving the user experience.

Figure 2B (As shown in the X direction) A sealing connection ensures the sealing of the upper side of the inner chamber 20. Furthermore, the second end 3102 of the pump core assembly is inserted into the first insertion hole 2012 and extends downward into the second receiving cavity 203. A sealing piston 33 is connected to the second end 3102 of the pump core assembly and sealably engages with the second end 202 of the inner chamber, ensuring the sealing of the lower side of the inner chamber 20. In other words, the sealing piston 33 and the inner chamber 20 together define the second receiving cavity 203 for storing the second product, so that the second product is surrounded between the inner chamber 20, the limiting member 40, and the sealing piston 33. Compared with the prior art sealing design that uses a sliding piston as the inner chamber seal, the sealing design of this embodiment, which directly seals the inner chamber 20 by combining the pump core assembly 31 with the inner chamber 20, has the advantages of simple structure, good sealing effect, and high stability.

[0076] For example, such as Figure 1B As shown, the bottle body 10 of this embodiment further includes a base 11 and a slidable vacuum piston 12. Specifically, the base 11 is connected to the second end 102 of the bottle body, and the base 11 and the inner wall 104 of the bottle body together define a first receiving cavity 103. The vacuum piston 12 is received in the first receiving cavity 103 and is press-fitted to the inner wall 104 of the bottle body along the second direction X, so that the first product is surrounded between the inner wall 104 of the bottle body, the inner chamber 20, the sealing piston 33 and the slidable vacuum piston 12.

[0077] Continue to refer to Figure 1B and combined Figure 2BThe aforementioned pump core assembly 31 is configured to be pushed by the pusher assembly 32 to displace relative to the inner chamber 20 and the limiting member 40 along a first direction Z. The sealing piston 33 is configured to be driven by the pump core assembly 31 to move relative to the inner chamber 20 along the first direction Z. Furthermore, the first end 201 of the inner chamber is fixedly disposed on the first end 101 of the bottle body 10 and is press-fitted to the first end 101 of the bottle body along a second direction X. A portion of the inner chamber 20 extends into the bottle body 10. That is, the second end 202 of the inner chamber is located inside the bottle body 10. The inner chamber 20 and the bottle body 10 are separated by the sealing piston 33. In this embodiment, the inner chamber 20 and the bottle body 10 can be interconnected by moving the sealing piston 33.

[0078] Therefore, in this embodiment, the dispenser 1 uses the pump core assembly 31, the limiting member 40 and the sealing piston 33 to seal and connect with the upper and lower sides of the inner chamber 20 (i.e. the first end 201 and the second end 202 of the inner chamber) respectively. By adopting multiple sealing measures at the top and bottom, a complete closed-loop sealing system is formed, which ensures the sealing performance of the inner chamber 20 itself and the inner chamber 20 and the bottle body 10, so as to achieve a high-efficiency sealing effect.

[0079] In addition, the pump core assembly 31 of this application embodiment can move along the first direction Z under the drive of the push head assembly 32, so that the dispenser 1 of this application embodiment includes different states based on the movement of the pump core assembly 31 relative to the inner chamber 20 along the first direction Z, namely the first state, the second state and the third state.

[0080] Specifically, such as Figure 1B As shown, in the first state, the push-button assembly 32 is not pushed, meaning the push-button assembly 32 is not subjected to external force. The pump core assembly 31 remains stationary relative to the inner chamber 20. The sealing piston 33 is sealed to the second end 202 of the inner chamber, thus separating the bottle body 10 and the inner chamber 20 by the sealing piston 33. At this time, the first product in the first receiving cavity 103 and the second product in the second receiving cavity 203 do not form a mixture.

[0081] In the second state, the push-button assembly 32 is pushed, meaning that the push-button assembly 32 is driven by an external force (e.g., a downward pressing force applied by the consumer in the first direction Z) to move the pump core assembly 31 downward relative to the inner chamber 20 in the first direction Z, causing the sealing piston 33 to move downward in the first direction Z, so that the sealing piston 33 is spaced apart from the second end 202 of the inner chamber. The inner chamber 20 is in communication with the bottle body 10, and the second product in the second receiving cavity 203 can enter the first receiving cavity 103 by gravity and form a mixture with the first product in the first receiving cavity 103. Exemplarily, in the second state, the pump core 311 of the pump core assembly 31 is still not activated; in other words, the pump core 311 is not yet actuated.

[0082] Furthermore, in the third state, the push-button assembly 32 is further pushed until the pump core assembly 31 connects with the limiting member 40. That is, the push-button assembly 32 is subjected to external force to continue driving the pump core assembly 31 to move downward relative to the inner chamber 20 in the first direction Z. Since the limiting member 40 of this embodiment is sleeved on the pump core assembly 31 and is fixedly and sealingly disposed at the first end 201 of the inner chamber, when the pump core assembly 31 moves downward relative to the inner chamber 20 and the limiting member 40 until the pump core assembly 31 connects with the limiting member 40, the limiting member 40 restricts the pump core assembly 31 from continuing to move downward in the first direction Z and restricts the movement of the sealing piston 33 in the first direction Z. At this time, when the consumer continues to apply external force to the push-button assembly 32, since the movement of the pump core assembly 31 in the first direction Z is restricted, the external force applied by the consumer can act on the pump core 311 of the pump core assembly 31, thereby actuating the pump core 311 to start the pump core assembly 31 and dispense the mixture.

[0083] Therefore, on the one hand, the dispenser 1 of this application embodiment utilizes the sealing connection between the limiting member 40, the sealing piston 33, and the pump core assembly 31 and the inner chamber 20, as well as the sealing connection between the inner chamber 20 and the bottle body 10, and adopts multiple sealing measures at the top and bottom to form a complete closed-loop sealing system, thereby achieving the sealing of the inner chamber 20 and the connection between the inner chamber 20 and the bottle body 10. On the other hand, through the limiting design between the limiting member 40 and the pump core assembly 31, when the consumer uses the dispenser 1 of this application embodiment, they can press the push-button assembly 32 to make the pump core assembly 31 move linearly downward to connect with the limiting member 40 and reach the limiting position, and drive the sealing piston 33 connected to the pump core assembly 31 to move downward synchronously relative to the inner chamber 20, so that the first product in the inner chamber 20 can be mixed with the second product in the bottle body 10.

[0084] The structure and working principle of the distributor 1 according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0085] refer to Figure 3A and Figure 3B The pump core assembly 31 of the dispenser 1 in this application embodiment includes a pump core 311 and a pump inner ring 312.

[0086] Specifically, such as Figure 3A and Figure 3B As shown, the pump core 311 is along the first direction (e.g. Figure 3A and Figure 3B Extending in the Z-direction (as shown), the pump core 311 has an inlet 3112 communicating with the first receiving cavity 103 and an outlet 3111 communicating with the discharge port 321 of the push-head assembly 32. The pump inner ring 312 is fixedly sleeved on the pump core 311. Furthermore, the pump core 311 is configured to move relative to the limiting member 40 in the first direction Z under the drive of the push-head assembly 32. For example, as... Figure 3BAs shown, the pump inner ring 312 has a through hole along the first direction Z, through which the pump core 311 passes and connects to the pump inner ring 312. The inner surface of the pump inner ring 312 has a protrusion, and the outer surface of the pump core 311 has a concave portion that matches the protrusion. Along the first direction Z, the lower surface of the protrusion abuts against the lower side surface of the concave portion, and the upper surface of the protrusion abuts against the lower side surface of the concave portion, so that the pump inner ring 312 and the pump core 311 are connected by a convex-concave fit, thereby enabling the pump inner ring 312 to move synchronously with the pump core 311 along the first direction Z relative to the limiting member 40.

[0087] Additionally, please continue to refer to Figure 3B and combined Figure 4A and Figure 4B In this embodiment of the application, the outer wall of the limiting member 40 is provided with a first engaging portion 41. For example... Figure 4A As shown, the lower surface of the pump inner ring 312 in this embodiment further includes four lower support legs 3121 extending downward along the first direction Z, and the inner wall of each lower support leg 3121 is provided with a second engaging portion 31211. Furthermore, as... Figure 4B As shown, the pump inner ring 312 also includes a second shoulder 3122 located on the inner surface, and the second shoulder 3122 is disposed opposite to the top surface 401 of the limiting member along the first direction Z.

[0088] Therefore, when the dispenser 1 of this embodiment is in the first and second states, along the first direction Z, the second shoulder 3122 of the pump inner ring 312 is spaced apart from the top surface 401 of the limiting member 40, and the first engaging portion 41 of the limiting member 40 is spaced apart from the second engaging portion 31211 of each lower support leg 3121. When the dispenser 1 of this embodiment is in the third state, the second shoulder 3122 of the pump inner ring 312 abuts against the top surface 401 of the limiting member 40. That is, the distance from which the sealing piston 33 of this embodiment moves relative to the second end 202 of the inner chamber to the aforementioned limiting position is limited by the limiting member 40.

[0089] Furthermore, the first engaging portion 41 of the limiting member 40 engages with the second engaging portion 31211 of each lower support leg 3121, so that the limiting member 40 engages with the pump inner ring 312, thereby restricting the pump inner ring 312 from moving relative to the limiting member 40 in the first direction Z, and further restricting the pump core assembly 31 and the sealing piston 33 from moving relative to the inner chamber 20 in the first direction Z, so as to achieve the limiting of the pump core assembly 31 and the sealing piston 33.

[0090] For example, such as Figure 5A As shown, in this embodiment of the application, the first latching portion 41 surrounds the outer wall of the limiting member 40 along a third direction (i.e., the circumferential direction of the dispenser 1, such as...). Figure 5AThe first outer buckle rib extends in the direction R, and the second snap-fit ​​portion 31211 is the first inner buckle rib extending in the third direction R, which surrounds the first direction Z. However, the specific structure of the first snap-fit ​​portion 41 and the second snap-fit ​​portion 31211 is not limited in the embodiments of this application, as long as the limiting member 40 and the pump inner ring 312 can be snapped together, for example, it can also be a snap-fit ​​connection.

[0091] Furthermore, the number of lower support legs 3121 of the pump inner ring 312 is not limited in this application embodiment. For example, the number of lower support legs 3121 of the pump inner ring 312 in this application embodiment can be two, three, five, six or more.

[0092] Continue to refer to Figure 3B and combined Figure 5B The limiting member 40 in this embodiment of the application further includes a first mounting part, and the first end 201 of the inner compartment further includes a second mounting part corresponding to the first mounting part. The first mounting part and the second mounting part are sealed together so that the limiting member 40 is sealed and mounted on the first end 201 of the inner compartment.

[0093] For example, in this embodiment of the application, the first mounting part is a first annular groove 42, and the second mounting part is a second annular groove 2011. However, this embodiment of the application does not specifically limit the structure of the first mounting part and the second mounting part, as long as the limiting member 40 can be sealed and connected to the inner chamber 20.

[0094] For ease of explanation, the following description will be based on the example of the first mounting part being the first annular groove and the second mounting part being the second annular groove.

[0095] Specifically, such as Figure 5A and Figure 5B As shown, the second annular groove 2011 is provided with a first insertion hole 2012, and the inner sidewall 20111 of the second annular groove extends upward from the bottom wall 20112 of the second annular groove and defines the first insertion hole 2012. The first annular groove 42 has a second insertion hole 43 corresponding to and communicating with the first insertion hole 2012, and the inner sidewall 422 of the first annular groove extends downward from the bottom wall 421 of the first annular groove and defines the second insertion hole 43. Along the first direction Z, the pump core 311 passes through the second insertion hole 43 and the first insertion hole 2012 in sequence, and is interference-sealed with the inner sidewall 422 of the first annular groove along the second direction X. Exemplarily, in this embodiment of the application, the inner sidewall 422 of the first annular groove is inclined towards the second insertion hole 43 along the third direction R, so that the inner sidewall 422 of the first annular groove is interference-sealed with the outer surface of the pump core 311.

[0096] Furthermore, the first annular groove 42 also has an installation space 44. The inner sidewall 422 of the first annular groove, the bottom wall 421 of the first annular groove, and the inner wall of the limiting member 40 located below the bottom wall 421 of the first annular groove together define the installation space 44. The inner sidewall 20111 of the second annular groove joins the first annular groove 42 upward along the first direction Z, so that the end of the inner sidewall 20111 of the second annular groove is accommodated in the installation space 44 and is sealed to the inner wall of the limiting member 40. Exemplarily, the outer surface of the inner sidewall 20111 of the second annular groove in this embodiment of the application is provided with a rib, and the inner wall of the limiting member 40 is also provided with a corresponding rib. Along the first direction Z, the rib of the inner sidewall 20111 of the second annular groove and the rib of the inner wall of the limiting member 40 are engaged vertically, so that the inner sidewall 20111 of the second annular groove is tightly connected to the inner wall of the limiting member 40.

[0097] Exemplarily, in some possible implementations, the limiting member 40 of this application embodiment further includes a second annular gasket 45 corresponding to the first annular groove 42. For example... Figure 5B As shown, the second annular gasket 45 is accommodated in the installation space 44 and is located between the bottom wall 421 of the first annular groove and the top surface of the inner sidewall 20111 of the second annular groove along the first direction Z, so that the first annular groove 42 and the second annular groove 2011 are sealed together along the first direction Z, thereby improving the sealing effect between the limiting member 40 and the first end 201 of the inner chamber.

[0098] The material used to manufacture the second annular gasket 45 is not specifically limited in this application embodiment. For example, the second annular gasket 45 in this application embodiment is a polyethylene (PE) gasket, but it is not limited to this. For example, it can also be a rubber gasket, etc.

[0099] Continue to refer to Figure 3B The pump core assembly 31 in this embodiment of the application also includes components along a first direction (e.g., Figure 3B (As shown in the Z direction) Through connector 313, the first end 201 of the inner compartment also includes a downwardly extending connector 2013.

[0100] Specifically, such as Figure 3BAs shown, along the first direction Z, one end of the pump core 311 with an inlet 3112 extends into the connector 313, and the inlet 3112 communicates with the connector 313, so that the pump core 311 and the connector 313 are in communication. That is, the product (e.g., a mixture of the first product and the second product) can pass through the connector 313 into the inlet 3112 of the pump core 311, and flow from the outlet 3111 into the pump head assembly 32 through the pump core 311. The connecting portion 2013 is located in the second receiving cavity 203 and extends downward, and the connecting member 313 is configured to be able to move relative to the first end 201 of the inner chamber along the first direction Z under the drive of the pump core 311.

[0101] Exemplarily, the connecting portion 2013 has a free end 20131 that is inclined inward along a third direction R. When the dispenser 1 of this embodiment is in the first state and the second state, along the first direction Z, the connecting member 313 passes through the first end 201 of the inner chamber and extends into the second receiving cavity 203, and is press-fitted to the free end 20131 of the connecting portion 2013 along the second direction X to improve the sealing effect between the connecting member 313 and the first end 201 of the inner chamber. When the dispenser 1 of this embodiment is in the third state, the connecting member 313 is entirely housed in the second receiving cavity 203, and the free end 20131 of the connecting portion 2013 and the pump core 311 are spaced apart along the second direction (not shown in the figure). However, this is not a limitation, and the structure of the connecting portion 2013 is not specifically limited in this embodiment, as long as the connecting portion 2013 can be sealed to the connecting member 313 to enhance the sealing performance between the pump core assembly 31 and the first end 201 of the inner chamber.

[0102] refer to Figure 6 and combined Figure 3B The sealing piston 33 in this embodiment includes a piston body 331, an inner groove 332, an outer groove 333, and a connecting channel 334. The inner groove 332 and the outer groove 333 are both located on the piston body 331 and are both along a third direction (e.g., ...). Figure 6 Extending in the direction of R (as shown), the outer groove 333 and the inner groove 332 extend along the second direction (i.e., the radial direction of the distributor 1, as shown in the middle R direction). Figure 6 (As shown in the X direction) are spaced outwards.

[0103] Specifically, such as Figure 6 and Figure 3BAs shown, the inner wall 3321 of the inner groove extends downward along the first direction Z to define a connecting channel 334 that passes through the piston body 331. The first end 3131 of the connector is accommodated in the inner groove 332 and sleeved on the inner wall 3321 of the inner groove. That is, the first end 3131 of the connector is tightly connected to the inner wall 3321 of the inner groove so that the connecting channel 334 extends into the connector 313. Thus, on the one hand, the inner groove 332 of the sealing piston 33 is configured to drive the piston body 331 to move along the first direction Z under the drive of the connector 313; on the other hand, the connecting channel 334 passes through the piston body 331 so that the connecting channel 334 communicates with the first receiving cavity 103, thereby allowing the connector 313 to communicate with the first receiving cavity 103 through the connecting channel 334.

[0104] For example, the outer sidewall 3322 of the inner groove is further provided with six support ribs 3323, each support rib 3323 extending upward from the piston body 331 along the first direction Z, so as to make the engagement between the inner sidewall 3321 of the inner groove and the first end 3131 of the connector tighter. However, the embodiments of this application do not specifically limit the number of support ribs 3323. For example, the number of support ribs 3323 can also be two, three, four, five, seven or more.

[0105] For example, the sealing piston 33 in this application embodiment also includes annular edges 335. The three annular edges 335 are spaced apart along the third direction R on the outer edge of the piston body 331 and extend upward from the outer side wall of the outer groove 333 to guide the second end 202 of the inner chamber into the outer groove 333.

[0106] When the dispenser 1 of this embodiment is in the first state, the second end 202 of the inner compartment is accommodated in the outer groove 333 and is interference-sealed with the inner sidewall 3331 of the outer groove along the second direction X, so that the sealing piston 33 is slidably and sealingly engaged with the second end 202 of the inner compartment. Exemplarily, the second end 202 of the inner compartment of this embodiment is interference-sealed with the inner sidewall 3331 of the outer groove, but this embodiment does not limit the connection method between the second end 202 of the inner compartment and the sealing piston 33, as long as the sealing piston 33 can be slidably and sealingly engaged with the second end 202 of the inner compartment.

[0107] When the dispenser 1 of this application embodiment is in the second state and the third state, the second end 202 of the inner compartment is spaced apart from the outer groove 333, that is, the sealing piston 33 is spaced apart from the second end 202 of the inner compartment, so that the inner compartment 20 and the bottle body 10 are in communication with each other, that is, the first receiving cavity 103 and the second receiving cavity 203 are in communication, and the second product in the second receiving cavity 203 can enter the first receiving cavity 103 by gravity.

[0108] refer to Figure 7 Along the first direction (e.g.) Figure 7 (As shown in the Z direction), in this embodiment of the application, the pump outer ring 34 is connected to the first end 101 of the bottle body and surrounds the pump inner ring 312. Exemplarily, in this embodiment of the application, both the inner wall 342 of the pump outer ring and the outer surface of the first end 101 of the bottle body are provided with corresponding ribs. Along the first direction Z, the ribs of the inner wall 342 of the pump outer ring and the ribs of the outer surface of the first end 101 of the bottle body are engaged vertically, so that when the pump outer ring 34 is connected to the first end 101 of the bottle body, the connection between the pump outer ring 34 and the bottle body 10 is more secure. However, this embodiment of the application does not specifically limit the connection method between the pump outer ring 34 and the first end 101 of the bottle body, for example, it can also be a threaded connection, etc.

[0109] like Figure 7 As shown, the inner wall 342 of the pump outer ring is provided with a third engaging portion 343, and the outer wall of the pump inner ring 312 is provided with a fourth engaging portion 3123 corresponding to the third engaging portion 343. Therefore, when the dispenser 1 of this embodiment is in the first state and the second state, the third engaging portion 343 of the pump outer ring 34 and the fourth engaging portion 3123 of the pump inner ring 312 are spaced apart along the first direction Z. When the dispenser 1 of this embodiment is in the third state, the third engaging portion 343 of the pump outer ring 34 engages with the fourth engaging portion 3123 of the pump inner ring 312 to restrict the movement of the pump inner ring 312 relative to the pump outer ring 34 along the first direction Z.

[0110] Furthermore, in this embodiment, the second engaging portion 31211 of the pump inner ring 312 is engaged and limited with the first engaging portion 41 of the limiting member 40, while the third engaging portion 343 of the pump outer ring 34 is engaged and limited with the fourth engaging portion 3123 of the pump inner ring 312. This further strengthens the anti-retraction design and achieves dual protection against retraction, preventing the pump core assembly 31 and the push-button assembly 32 from accidentally retracting.

[0111] For example, refer to Figure 7 and Figure 3A In this embodiment of the application, the third engaging portion 343 is the inner wall 342 surrounding the outer ring of the pump along a third direction (i.e., the circumferential direction of the distributor 1, such as...). Figure 3A The second inner retaining rib extends in the direction R (as shown in the middle R direction), and the fourth snap-fit ​​portion 3123 is the second outer retaining rib that extends in the third direction R around the outer wall of the pump inner ring 312. However, the specific structure of the third snap-fit ​​portion 343 and the fourth snap-fit ​​portion 3123 is not limited in the embodiments of this application, as long as the pump outer ring 34 and the pump inner ring 312 can be snapped together, for example, it can also be a snap-fit ​​connection.

[0112] For example, in this embodiment of the application, the inner wall 342 of the pump outer ring and the outer wall of the second annular groove 2011 are provided with mutually adapted vertical ribs so that when the pump outer ring 34 is sleeved on the first end 201 of the inner chamber, the connection between the pump outer ring 34 and the inner chamber 20 is more secure.

[0113] In addition, such as Figure 7 As shown, the inner wall 342 of the pump outer ring in this embodiment is further provided with four limiting ribs 345 spaced apart along a third direction R. Each limiting rib 345 extends along a first direction Z, so that when the distributor 1 of this embodiment is assembled with the pump core assembly 31, the limiting rib 345 can abut against the pump inner ring 312, facilitating the assembly of the elastic member 50 and the pump core 311. However, this embodiment does not specifically limit the number of limiting ribs 345; for example, the number of limiting ribs 345 can also be two, three, five, six, seven, or more.

[0114] Continue to refer to Figure 8 and Figure 5B and combined Figure 3A In this embodiment, the inner chamber 20 further includes a first annular flange 21 protruding from the outer surface 204 of the inner chamber, and the pump outer ring 34 further includes a first shoulder 344 located on the inner surface. The lower surface of the first annular flange 21 is provided along a second direction (e.g., the outer surface 204 of the inner chamber is perpendicular to the outer surface 204 of the inner chamber) Figure 3A The first sleeve 22 is set at intervals in the X direction (as shown in the middle X direction).

[0115] Specifically, such as Figure 8 As shown, along the first direction (such as...) Figure 8 (As shown in the Z direction), the first shoulder 344 is opposite to the first annular flange 21, and the first annular flange 21 is located between the first shoulder 344 of the pump outer ring 34 and the first end 101 of the bottle body. The first sleeve 22 is sealed to the inner wall 104 of the bottle body so that the inner chamber 20 is fixedly mounted on the bottle body 10 and sealed to the bottle body 10. Along the second direction (as shown in the Z direction), the first shoulder 344 is opposite to the first annular flange 21, and the first annular flange 21 is located between the first shoulder 344 of the pump outer ring 34 and the first end 101 of the bottle body. The first sleeve 22 is sealed to the inner wall 104 of the bottle body so that the inner chamber 20 is fixedly mounted on the bottle body 10 and sealed to the bottle body 10. Figure 8 (As shown in the X direction), the first sleeve 22 is located between the circumferential sidewall of the first annular flange 21 and the outer surface 204 of the inner chamber, and the first sleeve 22 is press-fitted to the inner wall 104 of the bottle body.

[0116] Exemplarily, in some possible implementations, the inner compartment 20 of this application embodiment further includes a first annular gasket 23. For example... Figure 8As shown, along the first direction Z, the first annular gasket 23 is located between the lower surface of the first annular flange 21 and the first end 101 of the bottle body, so that the first annular flange 21 and the first end 101 of the bottle body are sealed together along the first direction Z, thereby improving the sealing effect between the inner chamber 20 and the bottle body 10. This application embodiment does not specifically limit the material of the first annular gasket 23. For example, the first annular gasket 23 in this application embodiment is a PE gasket, but it is not limited to this; for example, it can also be a rubber gasket, etc.

[0117] Continue to refer to Figure 2B The push-button assembly 32 in this embodiment also includes a discharge channel 322. Specifically, as Figure 2B As shown, the first end 3221 of the discharge channel is connected to the discharge port 321, and the second end 3222 of the discharge channel is connected to the outlet 3111 of the pump core 311, so that the discharge port 321 and the outlet 3111 are connected. Thus, when the dispenser 1 of this embodiment is in the third state, the mixture from the first receiving cavity 103 can enter the connector 313 through the connecting channel 334, pass through the inlet 3112 of the pump core 311, and then enter the discharge channel 322 of the press head assembly 32 through the outlet 3111 of the pump core 311, and finally leave the dispenser 1 from the discharge port 321, thereby realizing the distribution of the mixture. However, this embodiment does not specifically limit the structure of the press head assembly 32. Exemplarily, the press head assembly 32 of this embodiment is composed of an aluminum cover, a nozzle and a press head. The aluminum cover is sleeved on the outside of the press head, the discharge channel 322 is provided inside the press head, and the nozzle has a discharge port 321.

[0118] The dispenser 1 in this embodiment further includes an elastic element 50, which is sleeved outside the pump core 311. Along the first direction Z, the elastic element 50 is located between the pump inner ring 312 and the limiting member 40, so that the pump inner ring 312 and the limiting member 40 are elastically connected, thereby biasing the pump inner ring 312 in the first direction Z. Exemplarily, the elastic element 50 in this embodiment is a spring, but the structure of the elastic element 50 is not specifically limited in this embodiment. It is acceptable as long as it enables the pump inner ring 312 to be elastically connected to the limiting member 40 to assist in adjusting the pressing force applied by the consumer, resulting in a good pressing feel. For example, it could also be a silicone element.

[0119] refer to Figure 9 and combined Figure 1BThe cover assembly 60 of this application embodiment includes an outer cover 61, a middle cover 62, and an inner cover 63 sequentially fitted from the outside in. Exemplarily, the outer cover 61 has a top piece 611 disposed on the side wall of the outer cover 61 along a first direction Z, and the top piece 611 engages with the side wall of the outer cover 61. Specifically, the inner cover 63 has a receiving space 631. When the cover assembly 60 is fitted onto the pump outer ring 34, the push-button assembly 32 is received within the receiving space 631 to protect the discharge port 321 of the push-button assembly 32 and prevent accidental actuation of the dispenser 1, thus affecting the consumer's experience. Exemplarily, the inner wall of the inner cover 63 is also provided with a plurality of vertical ribs 632 extending along the first direction Z. Along the third direction R, multiple vertical ribs 632 are spaced apart on the inner wall of the inner cover 63. When the cover assembly 60 is fitted onto the pump outer ring 34, the outer surface of the pump outer ring 34, which is accommodated in the accommodating space 631, abuts against the vertical ribs 632, so that the cover assembly 60 can be more securely fitted onto the pump assembly 30.

[0120] In addition, for aesthetic and ease of operation purposes, the dispenser 1 in this embodiment of the application further includes a decorative ring 70, which is disposed between the bottle body 10 and the cap assembly 60 along the first direction Z. Exemplarily, the bottle body 10, inner compartment 20, cap assembly 60, and decorative ring 70 in this embodiment of the application are made of plastic, but are not limited thereto; for example, they may also be made of metal or alloy.

[0121] The operation processes of the distributor 1 in the first, second, and third states according to embodiments of this application will be described in detail below. Specifically, they include:

[0122] In the first state, the first product is stored in the bottle body 10, and the second product is stored in the inner compartment 20. At this time, the push-button assembly 32 is not pushed, and the elastic member 50 biases the pump inner ring 312 upward. Under the action of the elastic member 50, each lower support leg 3121 of the pump inner ring 312 is spaced apart from the limiting member 40, the first locking portion 41 of the limiting member 40 is spaced apart from the second locking portion 31211 of each lower support leg 3121, and the third locking portion 343 of the pump outer ring 34 is spaced apart from the fourth locking portion 3123 of the pump inner ring 312. The pump core 311 is inserted into the inner chamber through the first insertion hole 2012 along the first direction Z. The pump core 311 is sealed to the limiting member 40. The sealing piston 33 is sealed to the second end 202 of the inner chamber. The connecting member 313 is sealed to the free end 20131 of the connecting portion 2013 of the first end 201 of the inner chamber, so that the inner chamber 20 is sealed closed. The bottle body 10 and the inner chamber 20 are separated by the sealing piston 33.

[0123] In this embodiment, the first end 201 of the inner chamber is connected to the pump core assembly 31 along the second direction X via an interference seal, achieving a seal on the upper part of the inner chamber 20. The second end 202 of the inner chamber is connected to the sealing piston 33 along the second direction X via an interference seal, achieving a seal on the lower part of the inner chamber 20. Compared with the prior art distributors that achieve inner chamber sealing through two pistons that can slide up and down, the distributor 1 in this embodiment achieves upper and lower sealing of the inner chamber 20 through the pump core assembly 31 and the sealing piston 33, eliminating the need for an additional piston at the first end 201 of the inner chamber. This design offers advantages such as simple structure, good sealing effect, and high stability.

[0124] In the second state, as the consumer pushes (e.g., presses down) the pusher assembly 32, the pusher assembly 32 pushes the pump core 311. Since the pump inner ring 312 is fixedly mounted on the pump core 311, the pump core 311 drives the pump inner ring 312 to move synchronously along the first direction Z relative to the inner chamber 20 and the limiting member 40, resisting the biasing effect of the elastic member 50 located between the limiting member 40 and the pump inner ring 312. The movement of the pump core 311 in the first direction Z pushes the connecting member 313 to move downward, thereby pushing the sealing piston 33 to move downward synchronously, thus opening the inner chamber 20 and allowing the second product to fall into the bottle body 10 containing the first product. At this time, the second product can enter the bottle body 10 by gravity for mixing, and the consumer can also shake the dispenser 1 to accelerate the mixing process, especially when the product is a powder. Exemplarily, in the second state, the pump core 311 is still not activated; in other words, the pump core 311 is not yet actuated.

[0125] In the third state, the consumer further pushes (e.g., presses down) the pump assembly 32, which continues to push the pump core 311 downwards in the first direction Z until the pump inner ring 312 moves downwards to a defined position. In this position, the second shoulder 3122 of each lower support leg 3121 of the pump inner ring 312 abuts against the top surface 401 of the limiting member, the first engaging portion 41 of the limiting member 40 engages with the second engaging portion 31211 of each lower support leg 3121, and the third engaging portion 343 of the pump outer ring 34 engages with the fourth engaging portion 3123 of the pump inner ring 312. The pump inner ring 312 is doubly restricted from retraction by the limiting member 40 and the pump outer ring 34. As the pump inner ring 312 can no longer displace relative to the first end 201 of the inner compartment, further pushing by the consumer on the pump assembly 32 causes the pump core 311 to start, realizing the dispensing of the mixture of the first and second products within the bottle body 10.

[0126] Furthermore, in the third state, after the dispenser 1 completes the mixing, the consumer releases the force (i.e., external force) applied to the pump head assembly 32. The pump core 311 is not actuated, but because the inner pump ring 312 is still subject to the dual anti-reverse restriction of the limiting member 40 and the outer pump ring 34, the dispenser 1 can wait for the next dispensing operation. In other words, after the dispenser 1 of this embodiment has completed the mixing operation of the first and second products at the end of the second state, the pump core 311 can be activated multiple times in the third state to perform dispensing operations.

[0127] Figure 10A and Figure 10B A second embodiment of the dispenser of this utility model is shown.

[0128] refer to Figure 10A and Figure 10B In this embodiment, the difference from the first embodiment is that the outer surface of the second reservoir (e.g., the outer surface 204 of the inner compartment) is provided with a second sleeve 24, and the outer end 2401 of the second sleeve is provided with a second annular flange 25. Furthermore, the connecting portion 2013 in this embodiment is always sealed to the connecting member 313. In addition, the remaining structure of the dispenser in this embodiment is the same as in the first embodiment, such as the first reservoir (e.g., the bottle body 10), the limiting member 40, and the pump assembly 30, etc., which will not be described again here.

[0129] For ease of explanation, the following explanation will be based on the example of the first storage container being the bottle body and the second storage container being the inner compartment.

[0130] In the embodiments of this application, such as Figure 10A and Figure 10B As shown, the inner compartment 20 in this embodiment of the application also includes a second sleeve 24 disposed on the outer surface 204 of the inner compartment, along the second direction (e.g. Figure 10A and Figure 10B (As shown in the Y direction), the second sleeve 24 is press-fitted to the inner wall 104 of the bottle body, and the outer end 2401 of the second sleeve is provided with a second annular flange 25.

[0131] Specifically, the second sleeve 24 in this embodiment includes an outer end, an inner end, and a middle portion. The inner end 2402 of the second sleeve is connected to the outer surface 204 of the inner chamber, the outer end 2401 of the second sleeve is spaced apart from the first end 201 of the inner chamber, and the middle portion 2403 of the second sleeve is press-fitted to the inner wall 104 of the bottle body along the second direction Y. That is, the opening of the second sleeve 24 in this embodiment is oriented upwards along the first direction Z, and the opening of the second end 202 of the inner chamber is oriented downwards along the first direction Z, thereby facilitating demolding of the inner chamber 20 during production and helping to improve the production efficiency and yield of the dispenser 1. However, this is not a limitation; the structure of the second sleeve 24 in this embodiment is not specifically limited, as long as it allows for a sealed connection between the first end 201 of the inner chamber and the first end 101 of the bottle body.

[0132] Along the first direction (e.g.) Figure 10A and Figure 10B (As shown in the Z direction), the first shoulder 344 of the pump outer ring 34 is disposed opposite to the second annular flange 25. The second annular flange 25 is located between the first shoulder 344 of the pump outer ring 34 and the first end 101 of the bottle body, and is sealed to the first end 101 of the bottle body along the first direction Z, so that the inner chamber 20 is fixedly disposed on the bottle body 10 and sealed to the bottle body 10.

[0133] In other words, in this embodiment, the first product is surrounded between the inner wall 104 of the bottle body, the inner chamber 20, the sealing piston 33, and the slidable vacuum piston 12. The inner wall 104 of the bottle body, the inner chamber 20, the sealing piston 33, and the vacuum piston 12 together define a first receiving cavity 103. The first end 201 of the inner chamber is press-fitted to the inner wall of the first end 101 of the bottle body, and the vacuum piston 12 is press-fitted to the inner wall 104 of the bottle body, so that the bottle body 10 of this embodiment forms a shape that, from a cross-sectional view (see [reference]), through the first end 201 of the inner chamber 20 and the vacuum piston 12. Figure 10B It features a closed annular sealing structure that is enclosed on all sides, making it simple in structure and reliable in function.

[0134] Continue to refer to Figure 10AIn this embodiment, the free end 20131 of the connecting portion 2013 is press-fitted to the connector 313 of the pump core assembly 31 along the second direction Y. Exemplarily, the free end 20131 of the connecting portion 2013 extends downward along the first direction Z and into the inner groove 332 of the sealing piston 33. This allows the dispenser 1 in this embodiment to be in the first, second, and third states, so that along the first direction Z, the connector 313 passes through the first end 201 of the inner chamber and extends into the second receiving cavity 203, and is press-fitted to the free end 20131 of the connecting portion 2013 along the second direction X. That is, the connecting portion 2013 in this embodiment always maintains a sealed connection with the connector 313 to ensure that the second product in the inner chamber 20 does not leak from the first end 201 of the inner chamber, thus improving the sealing effect between the connector 313 and the first end 201 of the inner chamber.

[0135] In other words, in this embodiment, the second product is surrounded between the inner wall of the inner chamber 20, the sealing piston 33, the connecting portion 2013, and the connector 313. The inner wall of the inner chamber 20, the sealing piston 33, the connecting portion 2013, and the connector 313 together define the second receiving cavity 203. The second end 202 of the inner chamber is press-fitted to the inner sidewall 3331 of the outer groove of the sealing piston 33, the free end 20131 of the connecting portion 2013 is press-fitted to the outer sidewall of the connector 313, and the inner sidewall of the connector 313 is press-fitted to the inner sidewall 3321 of the inner groove.

[0136] However, this application embodiment does not specifically limit the structure of the connecting part 2013, as long as the connecting part 2013 can be sealed to the connecting member 313. Based on this, it should be noted that this application embodiment does not specifically limit the connection relationship between the limiting member 40 and the pump core 311. In the first embodiment described above, the limiting member 40 and the pump core 311 are connected in an interference fit along the second direction Y, but this is not limited to this. Since the connecting part 2013 always maintains a sealed connection with the connecting member 313, the limiting member 40 in this application embodiment can also be slidably connected to the pump core 311. Furthermore, this application embodiment may omit the elastic member 50 described in the first embodiment.

[0137] In summary, the dispenser 1 provided in this application not only improves the sealing effect of the inner chamber and the bottle body through the upper and lower multi-seal design of the inner chamber and the inner chamber and the bottle body, but also eliminates the need to select pump cores with special fixed designs (such as pump inner rings that are limited by threaded connections) and pump cores with special sealing designs (such as pistons that are sealed with the first end of the inner chamber by a sliding seal). It can use a general-purpose pump core to achieve dual-material mixing, thereby reducing costs and improving the user experience.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
