Description

Technical Field

[0001] This utility model relates to the field of lipstick technology, specifically to a spiral reinforced shell for anti-breakage cosmetic lipsticks. Background Technology

[0002] Lipstick is a cosmetic used to apply to the lips to add color, beautify the lips, and enhance the makeup effect and temperament. Preventing breakage is very important because the lipstick is relatively thin and is easily affected by improper force or angle during use. Breakage will cause waste and affect the user experience.

[0003] As an indispensable item in daily makeup, lipstick is loved by consumers for its portability and practicality. However, the current lipstick design has a common and troubling problem: when users need to remove the lipstick cap, the connection between the cap and the inner tube is often too tight or lacks an effective cushioning mechanism. In addition, users may not control the force properly when removing the cap, which can easily cause lateral pressure on the lipstick, resulting in the lipstick breaking from the base or a fragile part, causing unnecessary waste. To address this, we propose a break-resistant spiral reinforced shell for cosmetic lipsticks. Utility Model Content

[0004] One of the technical problems this application aims to solve is that, due to the often tight connection design between the cap and the inner tube of the lipstick or the lack of an effective cushioning mechanism, the lipstick is easily subjected to lateral pressure unintentionally, causing the lipstick to break from the base or a vulnerable part.

[0005] To address the aforementioned technical problems, this application provides a fracture-resistant spiral-reinforced shell for cosmetic lipsticks, including a base and further comprising:

[0006] An inner shell is provided outside the inner shell, a lifting seat is provided inside the inner shell, a paste is provided at the top of the lifting seat, and a cover is provided at the top of the inner shell;

[0007] An anti-breakage unit is disposed within the inner housing. The anti-breakage unit includes a rod, a limiting block, a spring, and an insert block, which are used to drive the rod upward to protect the ointment.

[0008] In some embodiments, the inner housing has two elongated slots extending through its outer surface, the two slots being arranged opposite each other, the inner housing being fixedly connected to the base, and the top of the inner housing having an opening.

[0009] In some embodiments, a threaded groove is provided on the inner side of the outer shell, and the outer shell is rotatably sleeved on the outer shell of the inner shell. The width of the threaded groove is the same as the width of the long groove.

[0010] In some embodiments, two rotating shafts are fixedly connected to the outer side of the lifting seat, and push rods are fixedly connected to the top ends of the two rotating shafts. The outer ends of the two rotating shafts are respectively inserted into two long slots and engaged with threaded slots.

[0011] In some embodiments, the bottom of the cover has two slots, and a card block is fixedly connected to the inner side of each of the two slots. The two sets of slots and card blocks are arranged opposite to each other.

[0012] In some embodiments, the anti-breakage unit includes a rod inserted into the top of the inner housing, the bottom end of the rod extending into a long groove and fixedly connected to a limit block, a spring being sleeved on the rod, a plug being fixedly connected to the top end of the rod, and a plug groove being provided at the bottom of the plug.

[0013] In some embodiments, the anti-breakage unit is configured as two sets, which are arranged opposite to each other, and the two card blocks are respectively inserted into the two insertion slots.

[0014] This utility model has at least the following beneficial effects:

[0015] When removing the cap, you need to keep pulling the cap upwards. This will cause the anti-breakage unit to rise simultaneously, and the rod inside the anti-breakage unit will be pulled out. The rod can protect the balm. During this process, the cap will not come into contact with the balm. This can prevent the balm from being broken by accidentally removing the cap directly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] Please see Figures 1-6 This utility model provides a technical solution:

[0025] A spiral-reinforced shell for a lipstick designed to prevent breakage includes a base 1, an inner shell 2, and an anti-breakage unit 7. An outer shell 3 is provided outside the inner shell 2, and a lifting seat 4 is provided inside the inner shell 2. A paste 5 is located at the top of the lifting seat 4, and a cover 6 is located at the top of the inner shell 2. The anti-breakage unit 7 is located inside the inner shell 2 and includes a rod 71, a limiting block 72, a spring 73, and an insert 74, used to drive the rod 71 upwards, thereby protecting the paste 5.

[0026] The inner shell 2 has two elongated slots 21 extending through its outer surface. The two slots 21 are arranged opposite each other. The inner shell 2 is fixedly connected to the base 1. The top of the inner shell 2 is open. The inner side of the outer shell 3 has a threaded groove 31. The outer shell 3 is rotatably sleeved on the outer side of the inner shell 2. The width of the threaded groove 31 is the same as the width of the elongated slot 21. The outer side of the lifting seat 4 has two rotating shafts 41 fixedly connected. The top of each of the two rotating shafts 41 is fixedly connected to a push rod 42. The outer ends of the two rotating shafts 41 are respectively inserted into the two elongated slots 21 and engaged with the threaded grooves 31. This allows the rotating shafts 41 to move up and down with the cooperation of the threaded grooves 31 and the elongated slots 21, thereby driving the lifting seat 4 and the paste 5 to move up and down as a whole.

[0027] The bottom of the cover 6 has two slots 61, and the inner side of each slot 61 is fixedly connected to a block 62. The two sets of slots 61 and the blocks 62 are arranged opposite to each other. The blocks 62 at the bottom of the cover 6 cooperate with the insertion slots 75 for insertion and fixation.

[0028] The anti-breakage unit 7 includes a rod 71 inserted into the top of the inner shell 2. The bottom end of the rod 71 extends into the long groove 21 and is fixedly connected to a limit block 72. A spring 73 is fitted over the rod 71. An insert block 74 is fixedly connected to the top of the rod 71. An insertion groove 75 is provided at the bottom of the insert block 74. The anti-breakage unit 7 is configured in two sets, which are arranged opposite to each other. The two locking blocks 62 are respectively engaged with the two insertion grooves 75. It should be noted that when the rod 71 is pulled out of the inner shell 2 and the cover 6 is removed, the rod 71 will quickly return to its original position due to the rebound of the spring 73, so as to avoid blocking the ointment 5.

[0029] When using, first pull the cover 6 upwards. Since the bottom of the cover 6 is engaged with the insertion slot 75 via the locking block 62, the rod 71 can be raised. When the rod 71 is stretched to its limit, rotate the cover 6 to disengage the locking block 62 from the insertion slot 75. In this way, the cover 6 can be removed. During this process, since the rod 71 is pulled out, the two rods 71 ​​protect the ointment 5, thus avoiding the accidental breakage of the ointment 5 when the cover 6 is removed directly. Example 2

[0030] Please see Figures 1-6 This utility model provides one embodiment:

[0031] Based on Embodiment 1, another technical solution to prevent the ointment 5 from breaking is proposed. The anti-breakage unit 7 includes a rod 71 inserted into the top of the inner shell 2. The bottom end of the rod 71 extends into the long groove 21 and is fixedly connected to a limiting block 72. A spring 73 is provided on the outer sleeve of the rod 71. An insert block 74 is fixedly connected to the top of the rod 71. An insertion groove 75 is provided at the bottom of the insert block 74. Two long grooves 21 are provided through the outer shell 2. The two long grooves 21 are arranged opposite to each other. The inner shell 2 is fixedly connected to the base 1. The top of the inner shell 2 is open. A threaded groove 31 is provided on the inner side of the outer shell 3. The outer shell 3 is rotatably sleeved on the outer shell 2. It should be noted that when most of the ointment 5 is to be protruded from the inner shell 2, it is only necessary to rotate it to the position and hold the outer shell 3 to fix it still. In this way, the rod 71 will not rebound back to its position due to the spring 73.

[0032] With one hand holding the base 1, the other hand rotates the outer shell 3. The outer shell 3 rotates outside the inner shell 2, synchronously driving the threaded groove 31 to rotate. The rotation of the threaded groove 31 will drive the rotating shaft 41 to rise under the limit of the long groove 21, that is, drive the lifting seat 4 and the paste 5 to rise in a straight line. The rotating shaft 41 can drive the push rod 42 to rise synchronously. At the same time, when the paste 5 rises to half its length, the push rod 42 contacts the rod 71, and the push rod 42 pushes the rod 71 to rise. Since the rod 71 is fitted with a spring 73, the spring 73 provides a rebound force, so it can drive the rod 71 back to its original position, that is, drive the lifting seat 4 and the paste 5 to fall. In this way, the paste 5 can be prevented from completely protruding out of the inner shell 2 and breaking.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
