Description

Technical Field

[0001] This utility model relates to the structure of a cosmetic container, and more particularly to a pump-free, rotatable, dispensing cosmetic container. Background Technology

[0002] Nowadays, many cosmetic containers use pump dispensers for lotions or creams. Simply pressing the pump head dispenses the lotion or cream, a simple and convenient method that is popular with consumers.

[0003] However, this type of cosmetic container also has a problem: the pump head structure is generally quite complex and prone to accidental operation, leading to waste. Therefore, some people have designed a locking structure to prevent accidental operation, locking the pump head and unlocking it when squeezing is needed. While this structure solves the problem of accidental operation, it is more complex and costly. Moreover, since the container is filled by pressure suction, in many cases, even with a long pump head tube, cosmetic residue can still remain in the container, resulting in waste. Summary of the Invention

[0004] This invention provides a pumpless, rotatable, metering cosmetic container that eliminates the need for a pump head, has a simple structure, achieves quantitative extrusion, leaves minimal cosmetic residue, is low-cost, and avoids waste. It solves the technical problems of existing cosmetic containers where the pump head structure is complex, costly, and prone to leaving cosmetic residue, leading to waste.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: A pump-free rotatable quantitative cosmetic container includes a top cover and a shell. A discharge ring, rotatable relative to the shell, is provided between the top cover and the shell. A discharge hole is provided on the discharge ring. Rotation of the discharge ring drives a lifting ring to move axially. A cavity is provided between the lifting ring and the discharge ring, and a deformable storage bag is installed in the cavity. The opening of the storage bag communicates with the discharge hole. The lifting ring adjusts the size of the cavity, and the storage bag deforms according to the size of the cavity. A quantitative structure is provided below the discharge ring. Rotating the discharge ring drives the lifting ring to move axially, and the lifting ring squeezes the storage bag, compressing and deforming it, allowing the cosmetic material inside the storage bag to be squeezed out from the discharge hole. This rotational operation method is simple in structure and less prone to misoperation. Under the compression of the lifting ring, all the material inside the storage bag can be discharged, reducing waste. Furthermore, the quantitative structure designed below the discharge ring ensures the amount of material discharged.

[0006] Preferably, the metering structure includes elastic teeth located on the bouncing ring body, with the elastic teeth evenly distributed on the annular bottom surface of the bouncing ring body. The lower end surface of the discharge ring body is formed with a continuous wavy serrated surface. When the discharge ring body rotates, the wavy serrated surface and the elastic teeth pass over the lowest and highest points, giving the user a distinct bouncing sensation. Each tooth movement completes a metered extrusion, facilitating operation. The number of teeth can be designed as needed.

[0007] Preferably, a polygonal facet is formed on the bottom surface of the outer shell of the bouncing ring, through which an inner ring is connected. The inner ring is coaxial with the discharge cup, with one end abutting against the bottom surface of the bouncing ring and the other end fixed to the inner wall of the outer shell by a protrusion. The polygonal facet achieves circumferential relative fixation between the inner ring and the bouncing ring. The inner ring can completely cover the metering structure and the lifting ring structure, so even if the outer shell is made transparent, it will not affect the appearance.

[0008] Preferably, the bouncing ring body further includes a fixed ring body coaxial with the lifting ring body. The inner wall of the fixed ring body is threaded, and the outer circumferential surface of the lifting ring body is provided with external threads. As the lifting ring body rotates with the discharge ring body, the threads on the inner wall of the fixed ring body, and the fact that the fixed ring body remains stationary, allow the lifting ring body to move axially. This threaded lifting mechanism provides good stability, a simple structure, and convenient operation.

[0009] Preferably, the lifting ring includes a fixed plate and a rotating cylinder located below the fixed plate. The fixed plate has a polygonal surface, and the upper half of the inner wall of the discharge ring is formed with a polygonal hole. The length of the polygonal hole is not less than the axial movement length of the lifting ring. Storage bags can be easily installed on the fixed plate. Synchronous rotation of the discharge ring and the lifting ring is achieved through the engagement of the polygonal shaft hole. The structure is simple and the operation is convenient.

[0010] Preferably, the upper end of the discharge ring is provided with an outward flange, and a groove is provided on the inner wall of the outward flange. The upper end of the outer shell is evenly distributed with protrusions, which are engaged in the grooves of the outward flange.

[0011] Therefore, the pumpless rotatable quantitative cosmetic container of this invention has the following advantages: by rotating the discharge ring, the lifting ring moves axially, thereby squeezing the variable storage bag above the lifting ring and compressing the storage bag to its maximum extent, ensuring no waste of the material inside. Simultaneously, a bouncing toothed structure is arranged below the discharge ring to achieve quantitative control; quantitative control is completed simultaneously with dispensing, resulting in low cost, simple structure, and minimal waste of cosmetic materials.

[0020] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] Example:

[0022] like Figure 1 and 2 As shown in Figures 3 and 4, a pump-free, rotatable, dispensing cosmetic container includes a top cover 1, a dispensing ring 2, and a shell 3 arranged coaxially. A synchronously rotating lifting ring 7 is coaxially arranged within the dispensing ring 2, forming a cavity 6 between the top surfaces of the lifting ring 7 and the dispensing ring 2. A deformable storage bag 4 is placed within the cavity 6, and the storage bag 4 can be filled with lotion or cream, etc. The opening of the storage bag 4 communicates with the dispensing hole 5. The lifting ring 7 adjusts the size of the cavity 6 by raising and lowering it, causing the storage bag 4 to deform and expel the lotion or cream or other cosmetic from the storage bag 4. The lifting ring 7 is externally threaded to a spring-loaded ring 8, which includes a bottom surface 18 and a fixed ring 16 on the bottom surface 18. The fixed ring 16 has internal threads, and the bottom surface 18 is designed with elastic teeth 10. The bottom surface of the dispensing ring 2 is formed with a continuous wavy serrated surface 13 (e.g., [missing information]) that mates with the elastic teeth. Figure 5 (As shown). An inner ring 9 is installed on the outer side where the discharge ring 2 and the elastic toothed plate 10 contact, and the inner ring 9 covers the discharge ring 2 and the spring ring 8 inside. The outer circumferential surface of the inner ring 9 is formed with snap-fit ​​protrusions 22, and the inner wall of the outer shell is formed with snap-fit ​​grooves. The inner ring 9 is fixed to the outer shell 3 by the cooperation of the snap-fit ​​protrusions and the snap-fit ​​grooves.

[0023] like Figure 6As shown, the discharge ring 2 is a cylindrical body with one open end, and a discharge hole 5 is provided at the center of the closed end of the discharge ring 2. An outwardly flanged edge 12 is formed near the upper part of the discharge ring 2. The outer diameter of the outwardly flanged edge 12 is the same as the outer diameter of the outer shell. An annular groove is formed on the inner wall of the outwardly flanged edge 12. Evenly distributed protrusions 23 are formed at the upper end of the outer shell 3 where it connects to the discharge ring 2. The protrusions 23 engage with the groove of the outwardly flanged edge, connecting the discharge ring 2 to the outer shell 3. A protrusion 11 is formed on the upper outer wall of the discharge ring 2, and an annular groove is formed on the inner wall of the upper cover 1. The upper cover 1 and the discharge ring 2 are connected through the protrusion and the annular groove. A continuous wavy serrated surface 13 is formed at the open end of the discharge ring 2. A first polygonal hole 14 is formed on the upper side of the inner wall of the discharge ring 2, which engages with the first polygonal surface 16 of the fixed plate 20 above the lifting ring 7, thereby driving the lifting ring 7 to rotate.

[0024] like Figure 7 As shown, the bouncing ring 8 includes a bottom surface 18 and a fixed ring 16 integrally formed with the bottom surface 18. The inner wall of the fixed ring 16 is provided with internal threads, and the outer circumferential surface of the lifting ring 7 is externally threaded. When the lifting ring 7 is driven to rotate by the discharge ring 2, the bouncing ring 8 remains stationary. Therefore, the threaded lifting ring 7 can move axially within the fixed ring 16. Elastic teeth 10 are evenly distributed on the bottom surface 18 around the fixed ring 16. The elastic teeth 10 cooperate with the wavy sawtooth surface 13 of the discharge ring to achieve quantitative feeding. The number of elastic teeth 10 is not limited to the number shown in the figure; the figure is only one method. A second polygonal surface 17 is also formed on the bottom surface 18, and a second polygonal hole is also formed on the bottom surface of the inner ring, thereby fixing the inner ring 9 to the bottom surface of the bouncing ring 8.

[0025] like Figure 8 As shown, the lifting ring 7 includes a fixed disk 20 and a rotating cylinder 21 located below the fixed disk 20. The outer circumference of the fixed disk 20 is formed with a first polygonal surface 19. The upper half of the inner wall of the fixed disk 20 is formed with a first polygonal hole 14 to engage with the material discharge ring 7. The length of the first polygonal hole 14 is not less than the length of the axial movement of the lifting ring 7, allowing the lifting ring 7 to be rotated by the material discharge ring 2. An external thread is formed on the outer circumferential surface of the rotating cylinder 21 for engaging with the bouncing ring 8.

[0026] In use, open the top cover and rotate the discharge ring. Since the discharge ring and lifting ring are fixed together via a polygonal surface, rotating the discharge ring and lifting ring results in synchronous rotation. The rotating cylinder of the lifting ring is threadedly connected to the fixed ring. With the fixed ring stationary, the lifting ring moves axially, compressing the storage bag and reducing its cavity. The material inside the bag is then discharged through the discharge hole. Because the lower end face of the discharge ring engages with the elastic teeth, the change in the teeth is clearly felt when rotating the discharge ring, thus achieving quantitative extrusion. The outer shell can be made of transparent material, and the arrangement of the inner ring conceals the connection between the discharge ring and the spring ring within, preventing any impact on appearance. The discharge ring can rotate in two directions to extrude material or to rotate in the opposite direction to refill the bag or replace the storage bag.

[0027] The specific embodiments described herein are merely illustrative of the concept of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
