Technical Field
[0001] This utility model relates to lipstick, and more particularly to a lipstick with an anti-loss cap. Background Technology
[0002] Lipstick, a commonly used daily lip makeup product, mainly consists of a tube shell, a core, and a protective cap. The core contains the makeup product and is assembled inside the tube shell via a spiral guide groove, a spiral fixing sleeve, and structures such as beads and forks, allowing the product to be pushed out when the core is rotated. The protective cap works with the tube shell to cover the core, sealing the opening and protecting the makeup product inside.
[0003] The most common way to attach the protective cap and the tube shell is magnetically. This involves using magnetic blocks between the cap and the shell to quickly and easily secure the cap. However, lipsticks are frequently used and usually carried in a bag or pocket. A magnetically attached cap is prone to detaching from the tube shell in these situations, making it easy to lose. This affects both the protection of the lipstick and the overall appearance of the tube. Utility Model Content

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0031] Example 1
[0032] This embodiment discloses a lipstick with an anti-loss protective cap. Addressing the issue that existing lipsticks, when placed in bags or pockets or other environments prone to friction and impact, suffer from poor stability when magnetically attached to the tube shell, leading to the easy loss of the protective cap, this embodiment provides a targeted design. Based on the existing lipstick product structure, this embodiment incorporates a rotating lock assembly 4 and a locking hole 9 between the protective cap 2 and the tube shell 1. The cooperation between the rotating lock assembly 4 and the locking hole 9 enhances the connection stability between the protective cap 2 and the tube shell 1.
[0033] Specifically, the lipstick with an anti-loss cap disclosed in this embodiment mainly includes, as follows: Figure 4 The lipstick body shown and as Figure 2 The protective cover 2 shown.
[0034] The lipstick body includes a tube shell 1 and a central core 7 installed inside the body 1. The central core 7 and the tube shell 1 are assembled using the traditional lipstick structure with spiral guide grooves, spiral fixing sleeves, beads, forks, and other structures, allowing the central core to rotate relative to the tube shell 1, thereby enabling the lipstick to be pushed out and used. This is the existing structure of the lipstick tube, and will not be described in detail here.
[0035] The protective cover 2 is mainly used to protect the lipstick paste inside the core 7 from the outside of the core 7. The protective cover 2 covers the core 7 and is magnetically connected to the tube shell 1. The protective cover 2 and the tube shell 1 are respectively provided with magnetic blocks that attract each other, so that the protective cover 2 can be inserted and removed relative to the tube shell 1.
[0036] The entire lipstick tube has a rectangular parallelepiped structure. When the protective cap 2 is magnetically connected to the tube shell 1, it is ensured that the surfaces of the four side walls of the protective cap 2 and the tube shell 1 are flush. The flush side walls provide the structural basis for the setting of the circular groove 3, such as... Figure 1 As shown, a circular groove 3 is provided at the connection between the protective cover 2 and the tube shell 1.
[0037] The circular groove 3 is mainly used for the rotation lock assembly 4 and the lock hole 9. Since the circular groove 3 is concave relative to the side wall of the protective cover 2 and the tube shell 1, the rotation lock assembly 4 and the lock hole 9 do not protrude from the side wall surface, thus providing a certain degree of safety protection for the rotation lock assembly 4 and reducing the probability of abnormal opening of the rotation lock assembly 4.
[0038] To facilitate the introduction of the rotating lock assembly 4 and the lock hole 9, the circular groove 3 is divided into an upper groove 3a and a lower groove 3b. The upper groove 3a is located at the bottom of one side of the protective cover 2, and the lower groove 3b is located at the top of one side of the tube shell 1.
[0039] First, such as Figure 2 and Figure 3 As shown, a rotating lock assembly 4 is hinged within the upper groove 3a. Specifically, the rotating lock assembly 4 is rotatably mounted within the circular groove 3 via a screw 6. A threaded hole is provided on the protective shell 2 containing the upper groove 3a. The screw 6 is locked into the threaded hole to achieve the assembly of the rotating lock assembly 4 within the circular groove 3. Furthermore, by adjusting the tightness of the screw 6 and the threaded hole, the rotating lock assembly 4 can only rotate under external force.
[0040] Secondly, such as Figure 6 As shown, the rotary lock assembly 4 includes a rotary arm 41; a hinged through hole 42 for the screw 6 to pass through is provided at one end of the rotary arm 41, and the screw 6 passes through the hinged through hole 42 and is locked to the threaded hole in the upper groove 3a of the protective cover 2.
[0041] A spring button 11 is provided at the other end of the rotating arm 41; the specific structure of the spring button 11 is as follows: Figure 7 As shown, the spring button 11 includes a ball head button 11a and a compression spring 11b;
[0042] Among them, the ball-head button 11a has a hemispherical protruding button body structure; and, as Figure 7As shown, a mounting slot 43 is provided at one end of the rotating arm 41 where the spring button 11 is located, and the ball head button 11a and the compression spring 11b are assembled together in the mounting slot 43.
[0043] Furthermore, such as Figure 4 and Figure 5 As shown, a lock hole 9, which works in conjunction with the rotary lock assembly 4, is provided in the lower half-groove 3b. The lock hole 9 is a circular concave hole. The semi-circular ball head of the ball head button 11a matches the lock hole 9 in the lower half-groove 3b of the tube shell 1.
[0044] Therefore, when the rotating lock assembly 4 and the lock hole 9 work together, the rotating arm 41 is moved by the thumb of the user, causing the rotating arm 41 to slide toward the lock hole 9. When the ball head button 11a of the spring button 11 reaches the position of the lock hole 9, the compressed spring 11b is reset, causing the spring button 11 to spring up and slide into the lock hole 9, which is a circular concave hole. Thus, the connection between the protective cover 2 and the tube shell 1 is strengthened when the cover is closed by using the limiting effect of the ball head button 11a and the lock hole 9.
[0045] Similarly, when it is necessary to open the protective cover 2, the rotating arm 41 is turned by the thumb. Since the ball head button 11a and the circular concave locking hole 9 are arc-matched, under the pushing action of external force, the compression spring 11b is compressed, and the ball head button 11a can gradually disengage from the locking hole 9, thereby releasing the reinforced connection between the protective cover 2 and the tube shell 1. The protective cover 2, which is magnetically attached to the tube shell 1, can then be pulled out.
[0046] Furthermore, it should be noted that, in order to optimize the connection between the screw 6 and the rotating arm and the threaded hole on the protective cover, a washer 10 can be clamped between the screw 6 and the rotating arm 41; furthermore, a spring structure (not shown in the figure) can be added at this connection, so that the spring can be sleeved on the screw 6 and limited between the rotating arm and the protective cover. Correspondingly, groove structures for the spring end to be installed will be reserved at the end face of the hinge through hole 42 of the rotating arm and the end face of the threaded hole of the upper half groove 3a of the protective cover, thereby optimizing the rotation action of the rotating arm and reducing friction.
[0047] Furthermore, to prevent the ball head button 11a from completely disengaging from the mounting slot 43 of the rotating arm 41, such as Figure 7 As shown, a limiting groove wall 43a is formed at the top opening of the mounting slot 43, and an anti-disengagement ring 12 is formed around the ball head button 11a. The diameter of the anti-disengagement ring 12 is larger than the diameter of the top opening of the mounting slot 43. Thus, under the action of the limiting groove wall 43a and the anti-disengagement ring 12, the ball head button 11a can be prevented from disengaging from the mounting slot 43.
[0048] In summary, for the lipstick with an anti-loss cap disclosed in this embodiment, the reliability between the magnetically connected protective cap 2 and the tube shell 1 is further enhanced by the setting of the rotating lock assembly 4 and the lock hole. Typically, a circular groove 3 and the rotating lock assembly 4 and the lock hole are set on one side wall or the two symmetrical side walls of the protective cap 2 and the tube shell 1, which greatly reduces the occurrence of abnormal opening of the protective cap 2 and effectively avoids the loss of the protective cap. This not only ensures the protection of the lipstick in the core by the protective cap, but also helps to maintain the aesthetics of the lipstick tube.
[0049] Example 2
[0050] This embodiment discloses a lipstick with an anti-loss cover. Based on the structure disclosed in Embodiment 1, the rotation and sliding action of the spring button 11 of the rotary lock assembly 4 is further optimized.
[0051] like Figure 2 and Figure 3 As shown, an upper guide groove 5 is formed within the upper half of the groove 3a; as Figure 4 and Figure 5 As shown, a lower guide groove 8 is formed in the lower half groove 3b;
[0052] The upper guide groove 5 and the lower guide groove 8 together form a circular guide groove with the screw 6 as the center. Thus, during the rotation of the rotating arm 41, it can move along the trajectory of the circular guide groove formed by the upper and lower guide grooves, thereby realizing the guiding sliding effect of the upper guide groove 5 and the lower guide groove 8 on the spring button 11.
[0053] Furthermore, the upper guide groove 5 and the lower guide groove 8 have the same depth so that the spring button 11 can slide smoothly. Correspondingly, it is also necessary to ensure that the depth of the upper guide groove 5 and the lower guide groove 8 is less than the depth of the lock hole 9 in order to maintain the effectiveness of the lock hole 9.
[0054] Since the rotating arm 41 drives the ball head button 11a of the spring button 11 to slide along the upper and lower guide grooves, the corresponding lock hole 9 needs to be set in the lower guide groove 8 so that the circular concave hole of the lock hole 9 is smoothly recessed in the lower guide groove 8 so that the ball head button 11a of the spring button 11 can smoothly enter or slide out of the lock hole.
[0055] In summary, the guide groove structure of the lipstick with anti-loss cover disclosed in this embodiment is further optimized, so that the spring button 11 can slide more stably during the rotation of the rotating arm 41, thereby allowing the ball head button 11a of the spring button 11 to be more accurately and smoothly inserted into the lock hole to complete the locking function, thereby strengthening the connection between the protective cover 2 and the tube shell 1, and thus preventing the protective cover from being lost.
[0056] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
