Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

In this application, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any particular order or number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In this application, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements explicitly listed, but may include other elements not expressly listed or inherent to such system or apparatus.

In the prior art, the wick pushes out the lipstick body mainly by the relative rotation of the screw and the fork. For a push-to-pop lipstick tube, the center-bundle core is housed in the lipstick tube before use; in the state that the middle beam core is popped up and is not completely taken out, if the middle beam core is rotated (the screw and the fork rotate relatively), the lipstick body is pushed out to be propped against the middle beam core cover, and the whole lipstick body is damaged.

To solve the above problem, referring to fig. 1 and 2, an embodiment of the present application provides a pop-up packing tube, which includes an outer tube 10, a middle bundle core 20 and a driving assembly 30, wherein the middle bundle core 20 is received in the outer tube 10 and has a receiving state and a pop-up state opposite to each other. The driving assembly 30 acts on the core 20 to switch the housed state and the ejected state. The inner tube 40 is slidably disposed inside the outer tube 10 of the pop-up packing tube, and the inner tube 40 is always received in the outer tube 10.

In the accommodated state, the inner tube 40 and the entire middle core 20 (including the first member 21 and the second member 22 that are relatively movable in the circumferential direction) are all completely accommodated in the outer tube 10. In the prior art, the middle core 20 mainly comprises paste pushed by the relative circumferential movement of the screw and the fork, and the specific parts of the middle core 20 can be matched with each other as referred to in the background art, and will not be described herein. In the present embodiment, the first member 21 is integrated with the screw or fixed thereto, and the second member 22 is integrated with the fork or fixed thereto. The first part 21 and the second part 22 move relatively in the circumferential direction, namely the screw and the fork move relatively in the circumferential direction, and the paste is pushed out. It will be appreciated that the function of the core 20 is also achieved by exchanging the relative rotation of the helix and the fork.

In the ejected state, the second part 22 of the middle bundle core 20 is detached from the outer tube 10, and the first part 21 of the middle bundle core 20 remains in the inner tube 40. In the present embodiment, the resistance value between the inner tube 40 and the outer tube 10 is set small. The inner side wall of the inner tube 40 is circumferentially provided with a damping protrusion 423 which is in contact fit with the first part 21, when the second part 22 moves relative to the first part 21 (for example, the second part 22 is rotated by misoperation due to human reasons), the second part 22 drives the inner tube 40 to rotate relative to the outer tube 10 under the assistance of the damping protrusion 423, so that the paste inside the middle bundle core 20 is prevented from being pushed out and damaged.

In order to lock and unlock the inner tube 40, in an embodiment of the present application, referring to fig. 1 and 2, one end of the inner tube 40 is used to receive the first member 21 of the middle core 20, and the other end is provided with a clamping portion, when the clamping portion is effective, the axial positions of the inner tube 40 and the outer tube 10 are relatively fixed, and the inner tube 40 and the outer tube 10 are in a locked state and a receiving state. When the clamping part fails, the clamping part is in an unlocking state; in the unlocked state, the inner tube 40 and the outer tube 10 are pushed out by the driving assembly 30 into the ejected state. The engagement portion is deformable, and the drive assembly 30 causes the engagement portion to deform, switching the engagement portion from active to inactive. The engaging portion may be, for example, a claw 41 fixedly provided on the inner tube 40, and the claw 41 may be one or more.

The outer tube 10 is directly or indirectly fixedly provided with a positioning protrusion 111, in a locked state, each claw 41 is radially and relatively expanded outwards, the claws 41 and the positioning protrusion 111 form radial dislocation, and the inner tube 40 is limited to move towards the second part 22 of the middle core 20. The fixing manner of the positioning protrusion 111 and the outer tube 10 may be that the positioning protrusion 111 and the outer tube 10 are integrally formed, or that the positioning protrusion 111 and the outer tube 10 are separately fixed. In the separate fixing method, for example, at least a part of the positioning member 11 fixed inside the outer tube 10 is annularly and inwardly protruded in the radial direction, and the radially inwardly protruded part constitutes the positioning protrusion 111. In this embodiment, the split fastening method shown in fig. 2 is used. In this embodiment, one axial end of the cylindrical structure is turned inwards (corresponding to a radial inward protrusion) to form a positioning protrusion 111, and a mating surface 1110 is formed on one side of the positioning protrusion 111 facing the driving component 30; in the locked state, the latch 41 is radially displaced from the positioning projection 111, and the latch 41 is superposed on the mating surface 1110.

To effect unlocking of the drive assembly 30, in another embodiment, referring to fig. 2, the pawl 41 includes a catch 412 and a resilient arm 411. The elastic arm 411 is fixedly connected to the inner tube 40 and extends axially along the inner tube 40, and the hook 412 is located at the end of the elastic arm 411 where it extends and is fixed relative to the elastic arm 411. In the locked state, the claws 41 are radially displaced from the positioning protrusions 111 by the hooks 412, and the inner tube 40 is restricted from moving toward the second member 22 of the core 20. In the unlocked state, the driving element 30 acts on the hook 412, and the hook 412 is used to relatively gather, so that the radial dislocation is released by the driving element 30.

In this embodiment, the elastic arms 411 are independently disposed; any two circumferentially adjacent resilient arms 411 are provided with stress relief openings to avoid mutual traction. The resilient arm 411 may be in the form of an arcuate plate. For example, the inner tube 40 has a cylindrical structure, one axial end of the cylindrical structure is opened with a cross-shaped opening, one end of the inner tube 40 is divided into four arc-shaped plates, and the hook 412 is fixedly arranged on the arc-shaped plates. The number of the hooks 412 can be equal to or less than the number of the arc-shaped plates, so that the clamping parts are effective. For example, two hooks 412 are provided on arc plates circumferentially spaced one hundred eighty degrees apart.

In order to realize the switching function of the driving assembly 30, the hook 412 is provided with a first inclined surface 4121 towards the driving assembly 30, and the first inclined surface 4121 is subjected to an external force applied by the driving assembly 30. Since the hooks 412 and the positioning protrusions 111 are radially displaced and the axial position is restricted, the axial force applied to the first inclined surface 4121 is switched to a radial force, and the radial force urges the claws 41 to be gathered to release the radial displacement.

The driving assembly 30 includes a push cap 31 and a spring. The pressing cap 31 is arranged on the inner wall of the outer tube 10 in a sliding manner and is limited to be completely separated from the outer tube 10; the spring is abutted against the middle of the pressing cap 31 and the inner tube 40. The pressing cap 31 includes a cylinder 312 and a sealing head 311 at one end of the cylinder 312, and one side of the cylinder 312 facing the middle bundle core 20 is an open port. When the lock is used, the lock is unlocked by pressing the pressing cap 31, the first inclined surface 4121 is positioned on a moving path of the edge of the opening, the edge part of the opening is used as a force application part to press the hook 412, and radial dislocation between the hook 412 and the positioning protrusion 111 is released.

The pressing cap 31 is provided with an inner concave edge 313 in the direction away from the middle beam core 20, the outer tube 10 is provided with an inner flanging edge which is matched with the inner concave edge 313, and the pressing cap 31 is limited to be completely separated from the outer tube 10. The spring may be, for example, a coil spring 32. In the locked state, the spring is compressed; in the unlocked state, since the push cap 31 is restricted from being completely separated from the outer tube 10, the spring is restored by its own elasticity to push the inner tube 40 and the push cap 31 at the same time, so that the push cap 31 is restored and the inner tube 40 is ejected at the same time. The embodiment improves the use experience of the user through the asynchronous action of unlocking and popping.

In another embodiment, referring to fig. 2, to realize the function of a spring, a blocking portion 420 is provided inside the inner tube 40, and the blocking portion 420 of the inner tube 40 and each jaw 41 form a fitting space 421. When the claws 41 are relatively gathered, the volume of the fitting space 421 is reduced. One end of the coil spring 32 abuts against the sealing head 311 of the pressing cap 31, and the other end of the coil spring 32 extends into the fitting space 421 and abuts against the blocking portion 420 of the inner tube 40. In this embodiment, the spring is a coil spring 32. The pressing cap 31 is provided with a first positioning post 315 facing the sealing part 420, and the sealing part 420 is provided with a second positioning post 422 facing the pressing cap 31. The coil spring 32 is also engaged with the first positioning post 315 and the second positioning post 422 to limit the travel deviation of the spring. It is understood that the first positioning post 315 and/or the second positioning post 422 can also be hollow cylinders, at least one of which is disposed on the coil spring 32. The first positioning post 315 and the second positioning post 422 simultaneously act on the coil spring 32 to limit the radial movement of the coil spring 32, thereby ensuring that the force applied by the spring is maintained in the axial direction.

In order to maintain the direction of the force applied to the push cap 31, in another embodiment, referring to fig. 1 and 2, the outer tube 10 is provided with a positioning strip, such as a positioning rib 101, for limiting the relative movement of the push cap 31 and the circumferential direction thereof. When the push cap 31 is pushed, the circumferential movement of the push cap 31 is restricted, and the thrust of the push cap 31 is always kept in the axial direction.

In order to ensure that the driving assembly 30 is effectively unlocked and inhibit the unexpected movement direction, in another embodiment, referring to fig. 4 and 5, the inner wall of the outer tube 10 is further provided with a guide 120, and a side of the guide 120 facing the push cap 31 is provided with a second inclined surface 1201. When the cap 31 is pressed to unlock, the open port presses the hook 412, and at this time, the edge of the open port as a force application portion may be deformed radially outward due to the material. The second slope 1201 of the guide 120 is in the moving path of the opening edge, and the second slope 1201 of the guide 120 prevents the opening edge of the push cap 31 from being radially expanded outward, and prevents the unlocking function of the push cap 31 from being weakened or lost. The guide 120 may be fixed to the outer tube 10 in an integral manner, or may be fixed to the outer tube 10 as a separate member in an integral manner with the positioning member 11.

In order to limit the sliding stroke of the inner tube 40, in another embodiment, referring to fig. 4 and 6, the inner tube 40 and the outer tube 10 are respectively provided with a first positioning portion 43 and a second positioning portion 13 which are matched with each other, the inner tube 40 is pushed out by a spring in an unlocked state, and the first positioning portion 43 and the second positioning portion 13 limit the sliding stroke of the inner tube 40.

The first positioning portion 43 is provided on the outer wall of the inner tube 40, and the second positioning portion 13 is provided on the inner wall of the outer tube 10. For example, the first positioning portion 43 is an outer convex ring formed on the outer wall surface of the inner tube 40; the second positioning portion 13 is an inner collar fixed to the inner wall of the outer tube 10. When the first positioning portion 43 moves along with the inner tube 40, the second positioning portion 13 of the outer tube 10 is located on the moving path of the first positioning portion 43, the limit moving position of the inner tube 40 is limited, and the inner tube 40 is limited from being ejected out of the outer tube 10.

In order to simplify the manufacturing assembly and reduce the production cost, in another embodiment, referring to fig. 2 and 3, one end of the side wall of the inner tube 40 facing the second member 22 of the core 20 is used as a first positioning portion 43; the second positioning portion 13 may be a positioning step, which may be implemented by a protrusion independently provided on the inner wall of the outer tube 10, or may be implemented by a cylindrical structure fixedly provided inside the outer tube 10 as shown in fig. 3. The second positioning portion 13 is located on the moving path of the side wall of the inner tube 40, thereby limiting the sliding stroke of the inner tube 40.

In another embodiment, referring to fig. 1, 4 and 6, the inner wall of the outer tube 10 is provided with a limiting structure 14, the second part 22 of the middle bundle core 20 is provided with a positioning rib 221, and in the locked state, the limiting structure 14 is matched with the positioning rib 221, for example, in a manner of a slot, so as to limit the middle bundle core 20 in the outer tube 10. In the unlocked state, the spring pushes the middle core 20 to get rid of the resistance of the limiting structure 14 and the positioning rib 221, so that the second part 22 of the middle core 20 is ejected. The limit structure 14 can be a limit groove or a limit protrusion.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
