Description

Technical Field

[0001] This utility model relates to the field of cosmetics, and in particular to a cosmetic container that leaves no residue. Background Technology

[0002] Cosmetics are widely used in daily life. Currently, most lipsticks or lip balms on the market have a limited capacity where the product cup cannot be completely used up. This results in significant waste due to residual product, which is inconvenient for consumers and leads to a poor user experience.

[0003] Furthermore, consumers often have a preference for lipsticks that are used to their very last drop, typically because that shade might be a particular consumer's favorite. In such cases, it's somewhat disappointing if the remaining product is unusable. Therefore, users have raised new demands for lipstick-type cosmetic containers. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cosmetic container with no residue.

[0005] The technical solution of this utility model is: a cosmetic container with no residue, comprising: The base is tubular in shape, with an open upper part. The middle beam is rotatably mounted on the upper open end of the base, and both the upper and lower ends of the middle beam are open. When an external force is applied, the base and the middle beam rotate coaxially. A first push tube and a second push plate are coaxially arranged. The first push tube passes through the central beam and is located inside the base. The second push plate is located inside the first push tube. The first push tube is provided with a first pushing unit. Driven by the first pushing unit, the first push tube moves vertically. The second push plate is provided with a second pushing unit. Driven by the second pushing unit, the second push plate moves vertically. The first push tube and the second push plate are driven respectively, and the moving distance of the second push plate is greater than the moving distance of the first push tube. After the first push tube moves to its end, the first pushing unit stops driving the first push tube, and the second pushing unit continues to drive the second push plate. A first guide assembly is provided between the first push tube and the middle beam, and a second guide assembly is provided between the first push tube and the second push plate, wherein the guiding direction of the first guide assembly and the second guide assembly is the central axis of the middle beam.

[0006] Furthermore, the first guide assembly includes a first guide groove and a first guide block, with the first guide groove arranged vertically. The first guide groove and the first guide block can take various forms; any groove and protrusion that serves a guiding function can be used. For example, in this application, the first push tube passes through the central perforation of the middle bundle. Generally, the central perforation is circular, but in this application, the central perforation is configured as a D-shaped or circular hole with protrusions on both sides pointing inwards. Correspondingly, the outer side of the first push tube is cylindrical, with corresponding grooves or clearance grooves provided inwards, ensuring that both can move only in the vertical direction. Due to the threaded drive configuration, the technical solution shown in the accompanying drawings of this application is recommended.

[0007] Furthermore, the second guide assembly includes a second guide groove and a second guide block, with the second guide groove arranged vertically. This ensures that the relative movement between the first push tube and the second push plate is only vertical. Referring to the accompanying drawings, the second guide groove is provided on the outer side of the second push plate, and the first guide block is provided on the inner side of the first push tube, with the two cooperating with each other.

[0008] Furthermore, the first pushing unit employs a threaded drive, with a first internal thread and a first external thread engaging between the first push tube and the base. Through the engagement of the first internal thread and the first external thread, the first push tube can move vertically when an external force is applied to the base. The specific position of these threads can be adjusted according to actual needs.

[0009] Furthermore, the first internal thread is located inside the rotating sleeve, and the rotating sleeve is connected to the base via a limiting component, with the base driving the rotating sleeve to rotate synchronously. The rotating sleeve allows for external assembly of the first pushing unit, and assembly is performed via the rotating sleeve and base, improving assembly convenience.

[0010] Furthermore, the upper part of the rotating sleeve is provided with at least one spring-loaded groove, and the inner wall of the rotating sleeve corresponding to the spring-loaded groove is provided with at least one internal thread. When the first push tube moves to the end, the external force continues to drive it, and the upper part of the rotating sleeve springs outward, causing the internal thread to misalign with the first push tube. There are at least two interpretations for this misalignment. The first is that the threads are misaligned, which realizes the disengagement of the first push unit, and the two cannot continue to drive each other through the threads. The second is that the limiting protrusion abuts against the middle beam, and cannot continue to drive upward. However, at this time, the threads are still in an engaged state, but when pushing is continued at this time, it will be found that the threads jump (spring inward or outward).

[0011] Furthermore, a limiting protrusion is provided on the outer side of the first push tube, and when the first push tube is misaligned with the rotating sleeve, the limiting protrusion abuts against the lower end face of the middle beam. At this time, the first push tube cannot continue to move upward.

[0012] Furthermore, the limiting component includes: a limiting groove and a limiting post respectively, wherein the limiting post is inserted into the limiting groove. When one limiting post is provided, it is non-circular; two or more can also be provided, staggered respectively. In this case, whether it is circular or not is not limited, as long as it can stably limit the movement. This limiting insertion setting can ensure that the two rotate synchronously.

[0013] Furthermore, a coaxial positioning assembly is provided between the base and the rotating sleeve. This coaxial positioning assembly includes a positioning ring and a positioning groove arranged coaxially. One of them has a positioning ring, and the other has a positioning groove. The two are interlocked to ensure convenient assembly.

[0014] Furthermore, the second pushing unit employs a threaded drive, with threads fitting between the base and the second push plate. The rotation of the base drives the second push plate to continue moving.

[0015] Furthermore, a second column is provided at the center bottom of the base, the outer side of the second column is provided with external threads, and a second internal thread is provided at the center of the second push plate; or The second column is hollow with internal threads and external threads on the outside of the second push plate. The movement of the second push plate is achieved through the cooperation of the internal and external threads, and the specific position can be adjusted according to actual needs.

[0016] Furthermore, the first push tube is T-shaped, with its rod located inside the base and cooperating with the first push unit. The middle part of the first push tube is hollow, and a second push plate is installed inside. A material bin is installed at the top of the first push tube. This structure facilitates the placement of material in the material bin at the top of the first push tube, and facilitates the assembly of the material in the factory.

[0017] Furthermore, at least one material gripping groove is provided on the inner wall of the material bin of the first pusher tube. This ensures the stable storage of the material.

[0018] Furthermore, the second pusher plate is T-shaped, with its rod located inside the first pusher tube and its upper part located at the bottom of the material bin of the first pusher tube. The movement of the second pusher plate can push out the material inside the material bin, enabling the use of any remaining material.

[0019] Furthermore, the rod portion of the second push plate is hollow, and a push tube plug is provided on the upper side of the hollow channel. The push tube plug facilitates the effective setting of the second push plate.

[0020] Furthermore, an inner cover is provided on the top of the intermediate beam. The inner cover seals the top of the intermediate beam to ensure the stability of the material during the production and sales process and to avoid the influence of oxidation or other impurities.

[0021] Furthermore, the upper part of the base is detachably equipped with an outer cover, which surrounds the outer side of the middle beam. The outer cover ensures the presence of a protective sleeve and avoids contamination of the material. The connection between the outer cover and the middle beam can be achieved through snap-fit ​​connection, magnetic connection, threaded connection, etc.

[0022] The beneficial technical effect of this utility model is that the inventors of this application have designed a packaging container for lipstick tubes or lip gloss tubes that can leave no residue. After the first push tube is used to the end, the first push unit disengages, the second push unit continues to push, and the second push plate continues to push out the material in the material chamber, allowing the remaining material to continue to be used by the consumer in a normal manner until the material is completely used up without any residue, thus improving the consumer's user experience.

[0038] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0039] See appendix Figure 1-14 The cosmetic containers shown are free of residue and include: Base 1 is tubular in shape, with an open upper part; The middle beam 2 is rotatably mounted on the upper open end of the base 1, and both the upper and lower ends of the middle beam 2 are open. When an external force is applied, the base 1 and the middle beam 2 rotate coaxially. A first push tube 3 and a second push plate 4 are coaxially arranged. The first push tube 3 passes through the middle beam 2 and is located inside the base 1. The second push plate 4 is located inside the first push tube 3. The first push tube 3 is provided with a first pushing unit 5. Under the drive of the first pushing unit 5, the first push tube 3 moves in the vertical direction. The second push plate 4 is provided with a second pushing unit 6. Under the drive of the second pushing unit 6, the second push plate 4 moves in the vertical direction. The first push tube 3 and the second push plate 4 are driven respectively, and the moving distance of the second push plate 4 is greater than the moving distance of the first push tube 3. After the first push tube 3 moves to the end, the first pushing unit 5 stops driving the first push tube 3, and the second pushing unit 6 continues to drive the second push plate 4. A first guide component 7 is provided between the first push tube 3 and the middle beam 2, and a second guide component 8 is provided between the first push tube 3 and the second push plate 4, wherein the guiding direction of the first guide component 7 and the second guide component 8 is the central axis of the middle beam 2.

[0040] Furthermore, the first guide component 7 includes a first guide groove and a first guide block, with the first guide groove arranged vertically. The first guide groove and the first guide block can take various forms; any groove and protrusion that serves a guiding function can be used. For example, in this application, the first push tube 3 passes through the central perforation of the middle bundle 2. Generally, the central perforation is circular, but in this application, the central perforation is configured as a D-shaped or circular hole with protrusions on both sides pointing inwards. Correspondingly, the outer side of the first push tube 3 is cylindrical, with corresponding grooves or clearance grooves provided inwards, ensuring that both can move only in the vertical direction. Due to the threaded drive configuration, the technical solution shown in the accompanying drawings of this application is recommended.

[0041] Furthermore, the second guide assembly 8 includes a second guide groove and a second guide block, with the second guide groove arranged vertically. This ensures that the relative movement between the first push tube 3 and the second push plate 4 is only vertical. Referring to the accompanying drawings, the second guide groove is provided on the outer side of the second push plate 4, and the first guide block is provided on the inner side of the first push tube 3, with the two cooperating with each other.

[0042] Furthermore, the first pushing unit 5 adopts a threaded drive, with a first internal thread and a first external thread that cooperate with each other between the first pushing tube 3 and the base 1. Through the cooperation of the first internal thread and the first external thread, the first pushing tube 3 can move vertically when an external force is applied to the base 1. The specific setting position can be adjusted according to actual needs.

[0043] Furthermore, the first internal thread is located inside the rotating sleeve 9, and the rotating sleeve 9 is connected to the base 1 by a limiting component 10, with the base 1 driving the rotating sleeve 9 to rotate synchronously. The rotating sleeve 9 allows for external assembly of the first pushing unit 5, and assembly is performed via the rotating sleeve 9 and the base 1, improving assembly convenience.

[0044] Furthermore, at least one spring-loaded groove 91 is provided on the upper part of the rotating sleeve 9, and at least one internal thread is provided on the inner wall of the rotating sleeve 9 corresponding to the spring-loaded groove 91. When the first push tube 3 moves to the end, the external force continues to drive it, and the upper part of the rotating sleeve 9 springs outward, causing the internal thread to misalign with the first push tube 3. This achieves the disengagement of the first pushing unit 5, and the two can no longer be driven by the thread.

[0045] Furthermore, a limiting protrusion 31 is provided on the outer side of the first push tube 3, and when the first push tube 3 is misaligned with the rotating sleeve 9, the limiting protrusion 31 abuts against the lower end face of the middle beam 2. At this time, the first push tube 3 cannot continue to move upward.

[0046] Furthermore, the limiting component 10 includes: a limiting groove 101 and a limiting post 102 respectively, with the limiting post 102 inserted into the limiting groove 101. When one limiting post 102 is provided, it is set to be non-circular; two or more can also be provided, staggered respectively. In this case, whether it is circular or not is not limited, as long as it can stably limit the movement. This limiting insertion setting can ensure that the two rotate synchronously.

[0047] Furthermore, a coaxial positioning assembly is provided between the base 1 and the rotating sleeve 9. This coaxial positioning assembly includes a positioning ring and a positioning groove arranged coaxially. One of them is provided with a positioning ring, and the other with a positioning groove. The two are interlocked to ensure convenient assembly.

[0048] Furthermore, the second pushing unit employs a threaded drive, with threads fitting between the base 1 and the second push plate 4. The rotation of the base 1 drives the second push plate 4 to continue moving.

[0049] Furthermore, a second column is provided at the center bottom of the base 1, the outer side of the second column is provided with external threads, and a second internal thread is provided at the center of the second push plate 4; or The second column is hollow with internal threads and external threads on the outside of the second push plate 4. The movement of the second push plate 4 is achieved through the cooperation of the internal and external threads, and the specific position can be adjusted according to actual needs.

[0050] Furthermore, the first push tube 3 is T-shaped, with its rod located inside the base 1 and cooperating with the first push unit 5. The middle part of the first push tube 3 is hollow, and a second push plate 4 is installed inside. A material bin 32 is installed at the upper part of the first push tube 3. This structure facilitates the placement of material in the material bin 32 at the upper part of the first push tube 3, and facilitates the assembly of the material in the factory.

[0051] Furthermore, at least one material gripping groove is provided on the inner wall of the material hopper 32 of the first pusher pipe 3. This ensures the stable storage of the material.

[0052] Furthermore, the second pusher plate 4 is T-shaped, with its rod located inside the first pusher tube 3 and its upper part located at the bottom of the material bin 32 of the first pusher tube 3. Through the movement of the second pusher plate 4, the material inside the material bin 32 can be pushed out, realizing the use of the residual material.

[0053] Furthermore, the rod portion of the second push plate 4 is hollow, and a push tube plug 41 is provided on the upper side of the hollow channel. The push tube plug 41 facilitates the effective setting of the second push plate 4.

[0054] Furthermore, an inner cover 11 is provided on the top of the middle beam 2. The inner cover 11 seals the top of the middle beam 2 to ensure the stability of the material during the production and sales process and to avoid the influence of oxidation or other impurities.

[0055] Furthermore, an outer cover 12 is detachably installed on the upper part of the base 1, which surrounds the outer side of the middle beam 2. The outer cover 12 ensures the presence of a protective sleeve to prevent contamination of the material. The connection between the outer cover 12 and the middle beam 2 can be achieved by snap-fit ​​connection, magnetic connection, threaded connection, etc.

[0056] The inventors of this application have designed a packaging container for lipstick tubes or lip gloss tubes that leaves no residue. After the first push tube 3 is used to its end, the first push unit 5 disengages, the second push unit 6 continues to push, and the second push plate 4 continues to push out the material in the material chamber 32, allowing the remaining material to continue to be used by the consumer in a normal manner until the material is completely used up without any residue, thus improving the consumer's user experience.

[0057] In the actual assembly process, the outer cover and the base are detachably connected by snaps or magnets, and the inner cover is connected to the top of the middle beam by snaps. The inner cover can also be set to be used multiple times. It can be removed when in use and snapped back on when not in use.

[0058] The middle tube and the base are also interlocked, allowing them to rotate coaxially. The rotating sleeve is fitted inside the base, and the two rotate synchronously. The first external thread of the first push tube and the first internal thread of the rotating sleeve cooperate to reciprocate vertically. When the material reaches the end, rotation continues. At this point, the first internal and first external threads can either misalign and not engage, or they can continue to engage. The key is the contact between the limiting protrusion and the lower end of the middle tube, which restricts the first push tube from moving upward. If the threads continue to engage, slippage occurs, i.e., the spring groove takes effect. Alternatively, they may not engage further without external force, making further driving impossible. Both are possible. As rotation continues, the second external thread built into the center of the base continues to drive the second push plate upward through the second internal thread, pushing the remaining material out until it is completely used.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
