Technical Field

[0001] The utility model relates to the field of cosmetics, in particular to a lipstick tube. Background Art

[0002] At present, makeup has become an indispensable part of people's daily life. Cosmetics are also in various forms, such as powder, liquid, paste, etc. In order to facilitate the use of cosmetics, people generally make different cosmetics into different shapes and put them in suitable containers. Among them, paste-like cosmetics, such as lipstick, lip balm, concealer, skin whitening stick and sunscreen stick, are generally placed in tubes, which we generally call lipstick tubes or lipstick, lip balm, etc.

[0003] In the existing lipstick tube, by twisting the shell, the internal spiral tube cooperates with the beads or bumps and drives the cup body carrying the paste to move up and down reciprocatingly, so that the user can apply it.

[0004] Of course, in order to improve the user's feel, more effort is usually spent on the craftsmanship of the spiral tube and the bump, and the coordination between the two, and the manufacturing becomes more precise, which leads to an increase in production costs. After long-term use, when screwing the lipstick, it will become unsmooth and have a jumping feeling, and the stability will also become reduced. This leads to a significant reduction in the user's experience of using this lipstick, and there are deficiencies in the feel of use, which even seriously affects their shopping experience.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 4The utility model provides a lipstick tube, comprising: a lower shell 2, a tube body 7 which is adhered to the lower shell 2 and has an inner spiral 71, the height of the tube body 7 is lower than the height of the lower shell 2, so as to facilitate the reasonable assembly of other subsequent components, wherein the tube body 7 is hollow, and a ring edge 72 is extended inward at the bottom thereof, so as to make the tube body 7 and the lower shell 2 fit more firmly and increase the fitting area. The inner spiral 71 of the tube body 7 is manufactured by a stretching process, the surface quality of the thread is high, and the burrs or scratches generated by the traditional cutting process are avoided, and the tube body 7 undergoes plastic deformation during the stretching process, which improves the tensile strength and fatigue strength, and the precision is also improved.

[0030] In addition, the middle bundle tube 4 arranged in the tube body 7 is provided with a flange portion 41 on the middle bundle tube 4, the flange portion 41 includes an upper arc-shaped end 411 and a lower arc-shaped end 412, and the surface protruding from the middle bundle tube 4 is arranged in an annular shape, and an accommodating space 9 is formed between the lower arc-shaped end 412 of the flange portion 41 and the top of the tube body 7, that is, a space enclosed by the lower arc-shaped end 412, the surface of the middle bundle tube 4, the top of the tube body 7 and the inner wall of the lower shell 2; a support member 5 is arranged in the space, and the support member 5 contacts the inner wall of the lower shell 2 and abuts against the tube body 7, so that the lower shell 2 can highlight its twisting feel when it is screwed, and can also prevent the top of the tube body 7 from directly contacting the lower arc-shaped end 412 of the flange portion 41, so as to avoid friction affecting the feel of use, wherein the support member 5 is an elastic annular ring, preferably an O-ring, to avoid hard contact between the components.

[0031] The support member 5 is pressed down to the surface of the top of the tube body 7 by the flange 41. During this downward pressure, the contour formed between the lower arc-shaped end 412 of the flange 41 and the surface of the middle beam tube 4 can also match the contour of the support member 5, increasing the pressing force on the support member 5 and keeping it stable. In addition, the support member 5 can keep the tube body 7 stable, so that the downward pressure is transmitted to the ring edge 72 at the bottom. At the same time, it can be seen from the figure that the diameter of the support member 5 is much larger than the thickness of the tube body 7, and it can resist the surface of the middle beam tube 4, so that the inner spiral 71 does not interfere with the surface of the middle beam tube 4, and always maintains a certain gap to prevent friction when twisting the lipstick, which affects the feel of use and even noise, affecting the experience.

[0032] In addition, a middle sleeve 3 is sleeved on the middle bundle tube 4, and the middle sleeve 3 is composed of an extension portion 31 and an insertion portion 32. The insertion portion 32 is inserted between the tube body 7 and the middle bundle tube 4 and pressed against the upper arc-shaped end 411 of the flange portion 41 to restrict the support member 5, and further press the support member 5 to keep it stable and prevent jumping between the structures of the components.

[0033] The extending portion 31 contracts relative to the extending portion 32 toward the middle bundle tube 4, so that a retention space 8 is formed between the extending portion 32 and the middle bundle tube 4 to facilitate the rotation of the lower shell 2. If the retention space 8 is missing and is completely filled, the rotation of the lower shell 2 will be affected.

[0034] A vertical groove 42 is symmetrically formed through the middle beam tube 4 , and an opening of the vertical groove 42 is located at the bottom of the middle beam tube 4 .

[0035] A support tube 6 is disposed in the middle bundle tube 4 , and a protrusion 63 is disposed on the support tube 6 . The protrusion 63 passes through the vertical groove 42 and extends into the groove of the inner spiral 71 , so that when the tube body 7 rotates, the support tube 6 performs a lifting and reciprocating motion.

[0036] The above-mentioned cooperation between the vertical groove 42 and the protrusion 63 realizes the stable movement of the support tube 6 in the middle bundle tube 4, and the overall structure is relatively compact, and the weight of the components is also reduced.

[0037] The protrusion 63 is a polygon and is arranged in an inclined manner. It is preferably a parallelogram here. When the tube body 7 rotates, the protrusion 63 will be embedded in the wall of the groove, thereby preventing the protrusion 63 from accidentally detaching or loosening during movement, which can increase the stability and safety between the components. In addition, during the movement, the inclined setting of the protrusion 63 can reduce the contact area with the wall of the groove, thereby reducing friction. This helps to reduce friction loss and energy consumption and improve efficiency. It can also make the supporting tube 6 subject to uniform force and reduce vibration and impact during movement. This helps to improve its stability and provide smoother movement.

[0038] The supporting tube 6 is provided with a supporting plate 62 that is bent inward and carries the paste, and a clamping block 61 extending inward is provided in a ring shape at an opening of the supporting tube 6. This reinforces and supports the paste, ensures stability during engagement, and prevents the paste or other components from slipping or falling off during the lifting process.

[0039] The outer surface of the middle sleeve 3 is provided with a protrusion 311, and the upper cover 1 is engaged with the lower shell 2 by engaging with the protrusion 311, which effectively increases the tightness between the middle sleeve 3 and the upper cover 1, and prevents external environmental factors such as dust and moisture from entering the interior of the component.

[0040] The overall structure of the lipstick tube can be made of plastic or metal material, preferably all-aluminum material, which highlights the comfortable hand feel, gives people a visual effect with high-quality texture, can be protected from external damage, and the material can be recycled.

[0041] In some instances, for the installation of lipstick tube paste, see Figure 5As shown, the paste can also be inserted inward from the bottom. On the one hand, this is done to facilitate installation. On the other hand, after the paste is used for a short time, the paste can be directly pushed out for replacement.

[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
