[0056] The following will be combined with the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described in this application are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0057] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the following drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0058] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0059] Embodiment 1: As shown in FIG1-19, a squeeze-type cosmetic container includes a first one-way valve assembly 300, a second one-way valve assembly 400 and a bottle assembly 500. The bottle assembly 500 includes a bottle mouth assembly, an inner bag 530 and an outer bottle 540. The outer bottle 540 is provided with a shoulder 541, and a vent 542 is provided on the shoulder 541. The inner bag 530 is provided inside the outer bottle 540, and a gap 543 is provided between the inner bag 530 and the outer bottle 540. The vent 542 is connected to the gap 543. The bottle mouth assembly is fixedly inserted into the inner bag 530, and the bottle mouth assembly is fixedly connected to the outer bottle 540. The first one-way valve assembly 300 is installed in the bottle mouth assembly. The inner bag 530 is provided with a gap 543 between the inner bag 530 and the outer bottle 540. The material in the inner bag 530 can flow to the outside of the inner bag 530 through the first one-way valve assembly 300. The first one-way valve assembly 300 is fixedly installed on the bottle mouth assembly. The first one-way valve assembly 300 only allows the cosmetic material in the inner bag 530 to flow out from the inside of the inner bag 530 for user use, and does not allow external gas to flow into the interior of the inner bag 530, thereby ensuring that the material in the inner bag 530 will not be contaminated by external air and other pollutants, thereby extending the service life of the material; the second one-way valve assembly 400 is installed on the shoulder 541, and the second one-way valve assembly 400 is used to control the air outside the outer bottle 540 to enter the gap 543 through the vent 542. The second one-way valve assembly 400 is fixedly installed on the shoulder 541. The second one-way valve assembly 400 only allows external air to flow into the gap 543 through the vent 542, and does not allow the gas in the gap 543 to flow out. This ensures that when the user squeezes the outer bottle 540, the air pressure in the gap 543 increases, and the compressed gas is used to squeeze the inner bag 530, so that the material in the inner bag 530 breaks open the first one-way valve assembly 300 and flows out for the user to use. The material can be hand cream, body lotion, toner, etc.

[0060] In this application, the inner bag 530 is located inside the outer bottle 540, and the bottle mouth assembly is tightly inserted between the inner bag 530 and the outer bottle 540. A discharge channel is provided within the bottle mouth assembly, and the first one-way valve assembly 300 is mounted on the bottle mouth assembly. During use, the material flows out through the discharge channel of the bottle mouth assembly and the first one-way valve assembly 300 for the user. In this application, the bottle mouth assembly is used to connect and support the inner bag 530 and the outer bottle 540, and the second one-way valve assembly 400 is directly mounted on the shoulder 541 of the outer bottle 540. The second one-way valve assembly 400 is located inside the bottle shoulder 510, that is, the second one-way valve assembly 400 is not exposed. Therefore, the container is aesthetically pleasing, is not easily clogged by foreign matter, is easy to assemble, and has a simplified structure, reducing the production cost of the container. During use of the present application, the volume of the inner bag 530 gradually shrinks as the internal material decreases until the material in the inner bag 530 is used up. Therefore, the amount of material remaining in the inner bag 530 is small, which improves the utilization rate of the material and reduces the waste of resources.

[0061] As shown in Figures 1, 2, and 5, the cosmetic container further includes a massage cap 200, which is fixedly mounted on the bottle mouth assembly. The massage cap 200 is provided with a discharge port 210, and a first one-way valve assembly 300 is disposed within the discharge port 210. The massage cap 200 is provided with a concave massage surface 220. The upper surface of the massage cap 200 is the massage surface 220, which has an arc-shaped concave structure. During use, the user directly places the discharge port 210 against the skin surface, presses the outer bottle 540 to discharge the material through the first one-way valve assembly 300 within the discharge port 210, and then uses the massage cap 200 to evenly apply the material directly to the skin surface. Therefore, there is no need to squeeze the material onto the fingers and then use the fingers to apply the material, making it more convenient to use. Furthermore, the massage surface also provides a massage effect, improving user comfort.

[0062] Optionally, the massage surface 220 may be made of a temperature-sensitive material. Temperature-sensitive materials, also known as thermosensitive materials, are materials that undergo chemical or physical changes in response to heat, such as changes in elasticity, color, or shape. Massage surfaces 220 made of temperature-sensitive materials can undergo elastic deformation during massage, further enhancing the massage effect. Temperature-sensitive materials include metals, alloys, ceramics, glass, and stone.

[0063] The massage cover 200 can have a single peak, a double peak, or multiple peaks. As shown in FIG20 , the massage cover 200 has a double peak structure, with the two peaks having the same structure and size. As shown in FIG21 , the massage cover 200 has a double peak structure, with the two peaks having different sizes. As shown in FIG22 , the massage cover 200 has a triple peak structure, with each peak having the same or different structure or size. The massage surface 220 of the massage cover 200 in FIG20-22 is made of a temperature-sensitive material.

[0064] As shown in Figures 1-4, the bottle mouth assembly includes a bottle shoulder 510 and a bottle stopper 520. The bottle shoulder 510 is fixedly mounted on the outer bottle 540, the massage cover 200 is fixedly mounted on the bottle shoulder 510, the bottle stopper 520 is fixedly inserted into the inner bag 530, and the bottle stopper 520 is fixedly connected to the outer bottle 540. In this application, the bottle stopper 520 is tightly inserted into the inner bag 530 and the outer bottle 540, that is, the bottle mouth of the outer bottle 540 is fixedly sleeved on the upper end of the bottle stopper 520, and the bottle mouth of the inner bag 530 is fixedly sleeved on the lower end of the bottle stopper 520. A discharge channel is provided in the bottle stopper 520, the bottle shoulder 510 is fixedly connected to the outer bottle 540, and the massage cover 200 is fixedly connected to the bottle shoulder 510, that is, the bottle shoulder 510 is located between the massage cover 200 and the outer bottle 540, and the first one-way valve assembly 300 is installed between the massage cover 200 and the bottle shoulder 510. During use, the material flows into the massage cover 200 through the discharge channel of the bottle stopper 520 and the first one-way valve assembly 300. The user uses the massage cover 200 to evenly apply the material on the skin surface. It is easy to use and has a massage effect, thereby improving the absorption effect of the material and the comfort of the user.

[0065] As shown in Figures 1-2 and 4 , the first one-way valve assembly 300 includes a first one-way valve seat 320 and a first one-way valve 310 fixedly mounted on the first one-way valve seat 320. The first one-way valve seat 320 is fixedly mounted on the bottle shoulder 510 and the bottle stopper 520. As shown in Figure 15 , the first one-way valve 310 is sealingly mounted on the massage cover 200. This effectively prevents material from flowing out of the first one-way valve 310 from flowing back into the massage cover 200 and causing contamination inside the cosmetic container.

[0066] As shown in Figures 2 and 8, the first one-way valve seat 320 is provided with a support block 321, a boss 322 and a first clip 323. The support block 321 is located on one side of the first one-way valve seat 320, and the boss 322 and the first clip 323 are located on the other side of the first one-way valve seat 320. In Figure 8, the support block 321 extends toward the top of the first one-way valve seat 320, and the boss 322 and the first clip 323 extend toward the bottom of the first one-way valve seat 320. In this embodiment, the first one-way valve seat 320 is provided with two bosses 322 and two first clips 323. As shown in Figure 2, the first one-way valve 310 is sleeved on the support block 321, and a discharge channel is provided in the first one-way valve seat 320. The material is discharged through the discharge channel of the first one-way valve seat 320 and the first one-way valve 310. As shown in Figures 11-12, the bottle shoulder 510 is provided with a slot 511. In this embodiment, the bottle shoulder 510 is provided with two slots 511 symmetrically arranged along the central axis. The bottle stopper 520 is provided with a mounting slot 521. In this embodiment, the bottle stopper 520 is provided with two mounting slots 521 symmetrically arranged along the central axis. As shown in Figure 2, the boss 322 is fixedly installed in the mounting slot 521, and the first buckle 323 is engaged with the slot 511. The first one-way valve seat 320 is fixedly installed to the bottle stopper 520 via the boss 322 and fixedly installed to the bottle shoulder 510 via the first buckle 323, thereby improving the stability of the first one-way valve seat 320.

[0067] As shown in Figures 6 and 7 , the first one-way valve 310 is provided with a notch 311. The shape of the notch 311 includes at least one of a straight line, a T-shape, a cross shape, and a cross shape. During use, the user squeezes the outer bottle 540 to increase the air pressure in the gap 543. The compressed air squeezes the inner bag 530, causing the material in the inner bag 530 to break through the notch 311 and flow out through the opened notch 311 for the user to use. When the user releases the outer bottle 540, the air pressure in the gap 543 decreases, as indicated by the arrows above the first one-way valve 310 in Figures 17 and 18 . The pressure of the external air closes the notch 311, preventing external air from flowing into the inner bag 530 through the notch 311. This ensures that the material in the inner bag 530 is not contaminated by external air and other contaminants, thereby extending the service life of the material.

[0068] As shown in FIG. 1 , the second one-way valve assembly 400 includes a second one-way valve seat 420 and a second one-way valve 410 fixedly mounted on the second one-way valve seat 420 . The second one-way valve seat 420 is fixedly mounted on the shoulder 541 .

[0069] As shown in Figures 9 and 10 , the second one-way valve 410 is provided with a retaining ring 411 and a connecting rod 412. The second one-way valve seat 420 is provided with a mounting hole 421 and a vent 422. As shown in Figure 16 , the connecting rod 412 is airtightly mounted in the mounting hole 421, and the retaining ring 411 can seal the vent 422. As shown in Figures 14 and 15 , when a user squeezes the outer bottle 540, as indicated by the arrow on the outside of the outer bottle 540 in Figure 14 , the outer bottle 540 deforms, compressing the gas in the gap 543. As shown by the arrow in Figure 16 , the compressed gas presses against the retaining ring 411, causing it to seal the vent 422. Simultaneously, the increased gas pressure forces the material in the inner bag 530 to flow in the direction indicated by the arrow in the inner bag 530 in Figures 14 and 15 . Specifically, the material passes through the discharging channel of the bottle stopper 520 and the first one-way valve seat 320 , pushes open the incision 311, and flows out through the incision 311. As shown in Figures 17 and 18, when the user releases outer bottle 540, outer bottle 540 returns to its original shape, and the air pressure in gap 543 decreases. As indicated by the arrow in Figure 18, the external air closes incision 311. Simultaneously, as indicated by the arrow in Figure 19, the external air pushes open retaining ring 411 and enters gap 543 through air vent 422 and air vent 542, making the internal and external pressures of outer bottle 540 equal, and retaining ring 411 seals air vent 422 again. During this process, the volume of inner bag 530 gradually decreases as the material inside decreases until the material in inner bag 530 is used up. Therefore, the amount of material remaining in inner bag 530 is small, which improves material utilization and reduces resource waste.

[0070] As shown in Figures 13 and 16 , the sidewall of the shoulder 541 extends outward to form a protruding ring 544. The vent 542 is formed on the shoulder 541 within the protruding ring 544. The second one-way valve seat 420 is fixedly mounted on the protruding ring 544. The second one-way valve 410 is located between the vent 422 and the vent 542. When the internal and external air pressures of the outer bottle 540 are equal or the internal air pressure is greater than the external air pressure, the retaining ring 411 is attached to the second one-way valve seat 420 to seal the vent 422. When the external air pressure of the outer bottle 540 is greater than the internal air pressure, the retaining ring 411 moves away from the second one-way valve seat 420, allowing external air to enter the gap 543 through the vent 422 and the vent 542.

[0071] As shown in Figures 1-4, the squeeze-type cosmetic container also includes a cap assembly 100, which can be plugged and removably covered on the bottle mouth assembly, that is, the cap assembly 100 can be plugged and removably covered on the bottle shoulder 510. The cap assembly 100 includes an outer cap 110 and an inner cap 120 fixedly installed inside the outer cap 110.

[0072] As shown in FIG2 , the inner sidewall of the outer lid 110 is provided with a second latch 111, and the inner lid 120 is provided with a protrusion 121 and a third latch 122. The third latch 122 is fixedly engaged with the second latch 111 to securely connect the outer lid 110 and the inner lid 120. That is, the outer lid 110 and the inner lid 120 are secured by the second latch 111 and the third latch 122. The protrusion 121 seals against the first one-way valve assembly 300. Specifically, the protrusion 121 seals against the first one-way valve 310 to seal the incision 311. In this application, the lid assembly 100 is used to cover the massage cover 200 and the bottle shoulder 510, and the protrusion 121 seals the incision 311, thereby improving the sealing performance of the container. The inner lid 120 is designed to have a shape identical or similar to that of the massage cover 200, facilitating the sealing of the incision 311 by the protrusion 121.

[0073] Example 2: As shown in Figures 23-27, the difference between this example and Example 1 is that a metal sheet 230 is attached to the massage surface 220.

[0074] Example 3: As shown in Figure 28, the difference between this example and Example 1 is that: a convex point 221 is provided on the massage surface 220. A plurality of convex points 221 are provided on the massage surface 220 to further improve the massage effect of the massage surface 220.

[0075] Among them, in Figures 14 and 26, the arrow on the outside of the outer bottle 540 indicates the direction of the force exerted on the outer bottle 540 when the user squeezes the outer bottle 540, the arrow in the gap 543 indicates the direction of gas flow, the arrow inside the inner bag 530 indicates the direction of material flow, and the arrow inside the second one-way valve 410 indicates the direction of the force exerted by the gas inside the gap 543 on the second one-way valve 410; in Figures 17 and 27, the arrow on the outside of the first one-way valve 310 indicates the direction of the force exerted by the external air pressure on the first one-way valve 310, and the arrow on the outside of the second one-way valve 410 indicates the direction of the force exerted by the external air pressure on the second one-way valve 410.

[0076] The application process includes the following steps:

[0077] Step 1: Initially, the air pressure inside and outside the outer bottle 540 is equal, and the first one-way valve 310 and the second one-way valve 410 are closed;

[0078] Step 2: During use, the user squeezes the outer bottle 540 , as indicated by the arrow on the outer side of the outer bottle 540 in FIG14 , causing the outer bottle 540 to deform and compress the gas in the gap 543 , as indicated by the arrow in FIG16 . The compressed gas presses against the retaining ring 411 , causing the retaining ring 411 to seal the vent 422 .

[0079] Step 3: At the same time, the rising air pressure squeezes the material in the inner bag 530 to flow in the direction indicated by the arrows in the inner bag 530 in Figures 14 and 15. The material pushes open the incision 311 and flows out through the incision 311. The user uses the massage cover 200 to evenly apply the material to the skin surface.

[0080] Step 4: After use, the user releases the outer bottle 540 , as shown in FIG17 , and the outer bottle 540 returns to its original shape. The air pressure in the gap 543 decreases, as shown by the arrow in FIG18 , and the external air closes the incision 311 ;

[0081] Step 5: At the same time, as shown by the arrow in Figure 19, the external gas pushes open the retaining ring 411 and enters the gap 543 through the air hole 422 and the air vent 542, so that the internal and external pressures of the outer bottle 540 are the same, and the retaining ring 411 seals the air hole 422 again.

[0082] Step 6: The volume of the inner bag 530 gradually shrinks as the material inside decreases. Repeat the above steps until the material in the inner bag is used up.

[0083] It should be noted that those skilled in the art may make a number of modifications and improvements without departing from the concept of this application, and these modifications and improvements are all within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be based on the appended claims.
