Abstract
Description
Technical Field
[0001] This utility model relates to the field of cosmetic technology, and in particular to a lipstick tube. Background Technology
[0002] A lipstick tube is a container used to hold and protect lipstick. It typically consists of a tube body, a cap, and a screw mechanism. The tube body contains threaded parts or other types of lifting components. By rotating the screw mechanism, the lipstick extends upward from the tube body. When the lipstick needs to be used, the user needs to rotate the screw mechanism to extend the lipstick upward from the tube body. This process requires the user to rotate the screw mechanism several times before the lipstick can be extended from the tube body. Especially when there is little lipstick left, the user needs to rotate it even more times to expose the remaining lipstick, which is quite time-consuming. Moreover, frequent rotation of the screw mechanism can easily cause severe wear and tear on the internal threaded parts or lifting components, resulting in reduced stability during use. Utility Model Content
[0003] The purpose of this invention is to provide a lipstick tube that solves the problems of inconvenience and low stability in the use of existing lipstick tubes.
[0004] To achieve the above objectives, embodiments of this application provide a lipstick tube, comprising:
[0005] A base having a mounting groove, the bottom of the lipstick stick being engaged in the mounting groove;
[0006] A cylindrical body has a cavity for accommodating the lipstick paste extending through the cylindrical body along its axial direction. The cylindrical body is sleeved on the outer periphery of the base, and the wall of the cavity fits against the outer periphery wall of the base. The base is movable and connected to the cavity along the axial direction of the cylindrical body.
[0007] A cover, connected to the upper end of the cylinder, covers the top of the receiving cavity; and
[0008] A locking element is provided at the bottom of the cylinder, and the locking element is used to lock the base when the base is located in a preset position within the receiving cavity.
[0009] In some embodiments of this application, the lipstick tube further includes a gripping portion spaced coaxially with the base, the gripping portion being located on the outside of the base, and a through hole extending along the axial direction of the base between the gripping portion and the base, the tube being inserted into the through hole;
[0010] The perforation contains a connecting block that connects the gripping part and the base. A groove is radially passed through the cylinder for the connecting block to pass through. The groove extends axially along the cylinder to allow the cylinder to move axially and connect to the perforation.
[0011] In some embodiments of this application, one or more connecting blocks are provided, and the plurality of connecting blocks are axially spaced around the base; the number of sliding grooves is matched with the number of connecting blocks.
[0012] In some embodiments of this application, the lipstick tube further includes two sliding cavities coaxially disposed within the wall of the cylinder. The two sliding cavities are symmetrically arranged on both sides of the slide groove. A sealing plate is slidably installed in the sliding cavity along the circumference of the cylinder. Both sliding cavities are in communication with the slide groove. The sealing plate extends at least partially from the sliding cavity into the slide groove, and the outer periphery of the sealing plate is in contact with the inner wall of the slide groove.
[0013] An elastic element is connected between the sealing plate and the sliding cavity. The elastic element can undergo elastic deformation along the moving direction of the sealing plate so that the two sealing plates abut against each other on opposite sides.
[0014] In some embodiments of this application, the bottom of each of the two sealing plates on opposite sides is provided with a first inclined surface, and the two first inclined surfaces extend from top to bottom in a direction away from each other;
[0015] The upper end face of the connecting block is provided with a second inclined surface that matches the first inclined surface. When the cylinder is moved downward, the sealing plate slides into the sliding cavity under the guidance of the first inclined surface and the second inclined surface.
[0016] In some embodiments of this application, the bottom of the sliding cavity extends downward into the perforation.
[0017] In some embodiments of this application, the locking member includes a locking plate coaxially rotatably connected to the bottom wall of the cylinder, the locking plate is provided with an upwardly extending threaded member, and the bottom of the base is provided with a threaded hole that mates with the threaded member.
[0018] The projection of the gripping part along the vertical direction is located inside the projection of the locking plate along the vertical direction.
[0019] In some embodiments of this application, the cover is sleeved on the outer periphery of the upper end of the cylinder, the inner wall of the cover is provided with a snap-fit member extending circumferentially along the cover, and the outer periphery of the upper end of the cylinder is provided with a snap-fit groove that mates with the snap-fit member.
[0020] In some embodiments of this application, the outer peripheral wall of the cylinder located at the upper end of the snap-fit groove is provided with a third inclined surface. The third inclined surface is arranged along the circumference of the cylinder and is inclined from top to bottom away from the axial direction of the cylinder.
[0021] Compared with the prior art, the lipstick tube of this utility model has the following advantages: This solution adopts an axial sliding connection between the base and the cylinder. When lipstick is needed, the user only needs to release the locking device between the cylinder and the base, and then the base for holding the lipstick can be directly extended outward from the receiving cavity inside the cylinder. Compared with the traditional method of rotation, it takes less time and is more convenient to operate. Because the axial sliding connection between the base and the cylinder is adopted, the relatively complex driving method that requires the installation of threaded parts or other lifting components inside the tube is avoided, which leads to a decrease in stability during long-term use.

[0040] like Figure 1-11 As shown, this application embodiment provides a lipstick tube, including a base 1, as... Figure 7 As shown, the base 1 has a mounting groove 11. The bottom of the lipstick 5 is engaged in the mounting groove 11. Multiple limiting plates 15 are axially spaced around the base 1 within the mounting groove 11. When the lipstick 5 is inserted into the mounting groove 11, the limiting plates 15 are simultaneously inserted into the lipstick 5 (the insertion of the limiting plates 15 into the lipstick 5 causes corresponding parts of the lipstick 5 to be compressed, creating slots that match the limiting plates 15), thus achieving circumferential positioning of the lipstick 5 within the mounting groove 11; Figure 10 As shown, a receiving cavity 21 for accommodating lipstick 5 is provided through the cylindrical body 2 along its axial direction. The cylindrical body 2 is fitted around the outer periphery of the base 1. The inner wall of the receiving cavity 21 is in close contact with the outer periphery of the base 1. The base 1 is movably connected to the receiving cavity 21 along the axial direction of the cylindrical body 2 (the base 1 can only move axially within the receiving cavity 21 and cannot be removed from the receiving cavity 21); Figure 8 , Figure 9 As shown, the cover 3 is connected to the upper end of the cylinder 2 and covers the top of the receiving cavity 21 to seal the receiving cavity 21 so that the lipstick 5 is in a relatively sealed space (ensuring that the lipstick 5 is not contaminated); and the locking member 4 is provided at the bottom of the cylinder 2. When the base 1 is located at the preset position at the bottom of the cylinder 2, it is used to lock and position the base 1 to limit the axial movement between the base 1 and the cylinder 2.
[0041] When the lipstick tube is not in use, the cap 3 covers the top of the receiving cavity 21. At this time, the base 1 is located at the bottom of the cylinder 2, and under the action of the locking member 4, the base 1 cannot move axially relative to the cylinder 2. Thus, the cap 3, cylinder 2, and base 1 provide a relatively sealed space for the lipstick 5. When using the lipstick tube, the cap 3 needs to be opened first (so that the upper end of the lipstick 5 can extend upwards). Then, the user first releases the locking member 4 from the cylinder 2 and the base 1, so that the base 1 can move axially within the cylinder 2. At this time, the user inserts their finger from bottom to top into the cylinder 2 and abuts against the bottom of the base 1, pushing the base 1 upwards so that the lipstick is engaged in the receiving groove. The lipstick 5 protrudes from the top of the tube 2, making it ready for use. When the lipstick 5 needs to be retracted, the user withdraws their finger from the tube 2, and the base 1 moves downward within the tube 2 under its own weight until it returns to its initial position. The user then uses the locking element 4 to lock and position the base 1 and the tube 2 again, and then closes the cap 3 on top of the receiving cavity 21. Compared to the traditional method of using rotation and threaded parts 42 or other lifting components inside the tube to extend the lipstick upward, this method is simpler, more convenient, and less time-consuming. Moreover, the axial sliding connection between the base 1 and the tube 2 prevents damage during long-term use, improving its stability.
[0042] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 7As shown, the lipstick tube also includes a gripping part 12 spaced coaxially with the base 1. The gripping part 12 is located on the outside of the base 1, and there is a through hole 13 extending axially through the base 1 between the gripping part 12 and the base 1. The cylindrical body 2 passes through the through hole 13, and the outer wall of the cylindrical body 2 is in close contact with the inner wall of the through hole 13. A connecting block 14 is provided in the through hole 13 to connect and fix the base 1 and the gripping part 12. A radial through hole is provided on the wall of the cylindrical body 2. A groove 22 (extending axially along the cylinder 2) is provided so that when the cylinder 2 moves within the perforation 13, the connecting block 14 connecting the base 1 and the grip 12 can pass through the groove 22. At the same time, the size of the groove 22 matches the size of the connecting block 14 so that the cylinder 2 can move axially within the perforation 13 under the cooperation of the groove 22 and the connecting block 14 (restricting the cylinder 2 from circumferential rotation relative to the base 1 within the perforation 13).
[0043] This embodiment introduces a grip 12, which is more convenient than the method described in the previous embodiment where a finger is inserted into the tube 2 and pressed against the bottom of the base 1 to push the lipstick 5 upwards. When the lipstick needs to be used, the user holds the grip 12 (since the grip 12 and the base 1 are connected by the connecting block 14, the base 1 and the grip 12 remain synchronously stationary and are held by the user). After releasing the locking member 4 from the base 1, the user only needs to move the tube 2 downwards to expose the lipstick 5. After use, the user moves the tube 2 upwards to the initial position, and the locking member 4 locks the base 1 relative to the tube 2 again. Figure 10 As shown, when the slide groove 22 is opened, the upper end of the slide groove 22 is spaced a certain distance from the upper end of the cylinder 2 to ensure that the cylinder 2 will not come out of the perforation 13 when the user moves the cylinder 2 downward. When the top of the slide groove 22 abuts against the upper end of the connecting block 14, the cylinder 2 moves downward to the maximum distance (e.g., Figure 6 (As shown).
[0044] In some embodiments of this application, one or more connecting blocks 14 may be provided, and multiple connecting blocks 14 are axially spaced around the base 1. The number of sliding grooves 22 is matched with the number of connecting blocks 14. An example with two connecting blocks 14 and two sliding grooves 22 is shown in the figure of this application.
[0045] In some embodiments of this application, such as Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the lipstick tube also includes two sliding cavities 23 coaxially disposed within the wall of the cylinder 2. The two sliding cavities 23 are symmetrically arranged on both sides of the slide groove 22. A sealing plate 24 is slidably installed in the sliding cavity 23 along the circumference of the cylinder 2. Both sliding cavities 23 are connected to the slide groove 22. The sealing plate 24 extends at least partially from the sliding cavity 23 into the slide groove 22, and the outer periphery of the sealing plate 24 is in close contact with the inner wall of the slide groove 22. An elastic element 25 (a spring) is connected between the sealing plate 24 and the sliding cavity 23. The elastic element 25 can elastically deform along the moving direction of the sealing plate 24, so that the two sealing cavities 24 can be connected. The plates 24 on opposite sides abut together under the action of the elastic element 25, thereby sealing the slide groove 22 to prevent debris from the external environment from entering the cylinder 2 through the slide groove 22 and contaminating the lipstick 5. When the lipstick needs to be used and the cylinder 2 is moved downward, the two sealing plates 24 first retract into their respective slide cavities 23 (so that the slide groove 22 is unobstructed, and when the cylinder 2 moves downward, the two sealing plates 24 retracted into the slide cavities 23 will not affect the movement of the connecting block 14 in the slide groove 22), and then the cylinder 2 can be moved downward.
[0046] In some embodiments of this application, for the purpose of making it more convenient for users to operate, such as... Figure 5 As shown, in this embodiment, the bottom of each of the two sealing plates 24 facing each other is provided with a first inclined surface 241. The two first inclined surfaces 241 extend from top to bottom in a direction away from each other. A second inclined surface 141 matching the first inclined surface 241 is provided on the upper end surface of the connecting block 14. When the user holds the grip part 12 and moves the cylinder 2 downward, the first inclined surface 241 at the bottom of the sealing plate 24 and the second inclined surface 141 at the upper end of the connecting block 14 cooperate, which will force the sealing plates 24 to retract into their respective sliding cavities 23 (e.g., Figure 6 As shown, at this time, the elastic element 25 connected to the sealing plate 24 is compressed. As the cylinder 2 moves downward in the perforation 13, the side of the sealing plate 24 facing the connecting block 14 always abuts against the surface of the connecting block 14, until the top wall of the slide groove 22 abuts against the upper end face of the connecting block 14, at which point the cylinder 2 moves downward to its maximum distance. After use, the user moves the cylinder 2 upward until the two sealing plates 24 no longer abut against the connecting block 14 on the opposite side. Under the action of their respective elastic elements 25, the two sealing plates 24 extend outward from the slide cavity 23 again and abut together, sealing the slide groove 22.
[0047] In some embodiments of this application, such as Figure 3As shown, the bottom of the sliding cavity 23 extends downward into the perforation 13 (similarly, the two sealing plates 24 also extend downward to the same position). The connecting block 14 is disposed in the perforation 13 to connect the base 1 and the grip 12. The length of the connecting block 14 does not exceed the area where the perforation 13 is located. When the lipstick tube is not in use, the first inclined surface 241 of the bottom of the sealing plate 24 extending outward from the sliding cavity 23 just abuts against the second inclined surface 141 at the upper end of the connecting block 14 (as shown). Figure 3 , Figure 4 As shown, this is done to seal as much of the slide 22 as possible. The corresponding positions of the slide 22 and the connecting block 14 are also sealed under the action of the connecting block 14 (so that the entire slide 22 can be sealed) to ensure a good sealing effect.
[0048] In some embodiments of this application, such as Figure 8 As shown, the locking member 4 includes a locking plate 41 coaxially rotatably connected to the bottom wall of the cylinder 2 (the gripping part 12 is projected along the vertical direction onto the inner side of the projection of the locking plate 41 along the vertical direction), as... Figure 10 As shown, a stepped block 27 is provided at the bottom of the cylinder 2 (the stepped block 27 is arranged circumferentially around the cylinder 2), as... Figure 11 As shown, the locking plate 41 is provided with a stepped groove 411 that slides with the stepped block 27. Under the action of the stepped block 27 and the stepped groove 411, the locking plate 41 is coaxially rotated and installed at the bottom of the cylinder 2 (e.g., Figure 8 As shown), the locking plate 41 has an upwardly extending threaded part 42 (a screw), and the bottom of the base 1 has a threaded hole 43 that mates with the screw (as shown). Figure 8 (As shown); When the user needs to use the lipstick, the user first rotates the locking plate 41 (the cylinder 2 cannot rotate under the cooperation of the connecting block 14 and the sliding groove 22, at this time only the locking plate 41 rotates relative to the cylinder 2), so that the threaded part 42 is disengaged from the threaded hole 43 (during the process of rotating the locking plate 41 to disengage the threaded part 42 from the threaded hole 43, the cylinder 2 will move down a small distance synchronously in the through hole 13), at this time the locking position of the base 1 relative to the cylinder 2 is released; then the user can quickly pull down the cylinder 2 to expose the lipstick 5; in this embodiment, the length of the threaded part 42 does not need to be set too long, so that the user can release the locking position of the base 1 when rotating the locking plate 41 at a small angle.
[0049] The projection of the grip 12 along the vertical direction is placed inside the projection of the locking plate 41 along the vertical direction, so that the locking plate 41 acts as a base plate on the lipstick tube. When not in use, the locking plate 41 contacts the placement surface (improving the placement stability of the lipstick tube). On the other hand, when it is necessary to lock and position the base 1, the user first moves the cylinder 2 upward, so that the threaded part 42 moves with the cylinder 2 to the position of the opening of the threaded hole 43. Then the user rotates the locking plate 41 (so that the threaded part 42 is threaded into the threaded hole 43) so that when the upper end face of the locking plate 41 abuts against the lower end face of the grip 12, the locking plate 41 can no longer rotate (at this time, the two sealing plates 24 that are in contact with each other on one side again, and the first inclined surface 241 and the second inclined surface 141 are in corresponding contact). At this time, the base 1 and the locking plate 41 are connected together under the action of the threaded part 42 and the threaded hole 43, thereby realizing the locking and positioning of the base 1 relative to the cylinder 2.
[0050] In some embodiments of this application, such as Figure 8 , Figure 9 As shown, the cover 3 is fitted onto the outer periphery of the upper end of the cylinder 2. The inner wall of the cover 3 is provided with a snap-fit part 31 (the snap-fit part 31 is arranged along the circumference of the cover 3). The outer periphery of the upper end of the cylinder 2 is provided with a snap-fit groove 26 that cooperates with the snap-fit part 31. The cover 3 is a plastic structural part. When the cover 3 is closed on the upper end of the cylinder 2, the snap-fit part 31 is snapped into the snap-fit groove 26 to achieve the positioning of the cover 3. When the cover 3 needs to be removed, the cover 3 is pulled up forcefully. At this time, the side wall of the cover 3 undergoes a certain degree of deformation so that the snap-fit part 31 is withdrawn from the snap-fit groove 26.
[0051] In some embodiments of this application, such as Figure 9 As shown, the outer peripheral wall of the cylinder 2 located at the upper end of the snap-fit groove 26 is provided with a third inclined surface 28. The third inclined surface 28 is arranged around the cylinder 2 and is inclined from top to bottom away from the cylinder 2. The arrangement of the third inclined surface 28 helps the user to remove the cover 3 from the cylinder 2 or to close the cover 3 on the upper end of the cylinder 2. The arrangement of the third inclined surface 28 is used to guide the snap-fit member 31 provided on the inner wall of the cover 3, so that the snap-fit member 31 can be smoothly snapped into the snap-fit groove 26 or smoothly withdrawn from the snap-fit groove 26 when subjected to an upward pulling force.
[0052] The working process of this utility model is as follows: When the user needs to use the lipstick, first remove the cap 3 from the top of the tube 2, then hold the grip part 12 and rotate the locking plate 41 to release the locking and positioning of the base 1. Then move the tube 2 downward so that the lipstick 5 is exposed. After use, move the tube 2 upward so that the threaded part 42 moves to the threaded hole 43. Then rotate the locking plate 41 so that the threaded part 42 is screwed into the threaded hole 43, so that the upper end face of the locking plate 41 abuts against the lower end face of the grip part 12. At this time, the base 1 is locked and positioned relative to the tube 2.
[0053] In summary, this utility model embodiment provides a lipstick tube. This solution adopts an axial sliding connection between the base 1 and the cylinder 2. When lipstick is needed, the user only needs to release the locking member 4 from the locking between the cylinder 2 and the base 1, and then the base 1, which holds the lipstick 5, can be directly extended outward from the receiving cavity 21 inside the cylinder 2. Compared with the traditional method of rotation, it takes less time and is more convenient to operate. Because the axial sliding connection between the base 1 and the cylinder 2 is adopted, the relatively complex driving method that requires setting threaded parts 42 or other lifting components in the tube is avoided, which leads to a decrease in stability during long-term use. In order to further facilitate the user's use of the lipstick tube, a grip part 12 is provided on the outside of the base 1. In actual use, the user holds the grip part 12 and then operates the locking member 4 to release the locking between the cylinder 2 and the base 1, and then pulls down the cylinder 2 to expose the lipstick 5 contained in the base 1.
[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
