The utility model relates to a cosmetic container, in particular to a lipstick tube.

Background technique

Lips are an important part of the human face, and the beauty of the oral cavity is directly reflected by the lips. Beautiful lips can not only reflect the beauty, sexiness, maturity and nobility of a woman, but also reflect the handsome, free and easy, handsome and taste of a man. Dry and waxy lips will make people look old and lack energy. Therefore along with people's living standard improves day by day, more and more people begin to pay attention to the nursing of lip and beautification.

There are many kinds of lip cosmetics, the most commonly used are lipstick, lip balm and lip oil etc. at present. It accentuates the good points of the lips, giving them an alluring color and beautiful appearance. It can also cover up lip defects, such as adjusting the shape of the mouth, making the narrow uneven lips wider, and the wide sensual lips becoming narrower. In addition, proper use can also change the shape of the entire face, and it also has the function of moisturizing the lips, so it has become a must-have beauty cosmetic for people, especially women.

Lipstick or lip balm are generally packed in lipstick tubes. Common lipstick tubes on the market are usually composed of a cylindrical inner tube, an outer tube and a cap. The inner tube is sleeved in the outer tube, and a lipstick core is fixed inside the inner tube. The bottom of the inner tube is provided with a spiral lifting mechanism, which is used to rotate and push the upper inner tube to expand and contract relative to the outer tube, thereby driving the lipstick core to extend and retract. The tube cover is buckled on the outer tube, and fits on the outer tube to protect the lipstick core when not in use.

Existing lipstick tube nozzles are all circular horizontal sections, and this structural design has the following deficiencies, specifically as follows: one, the nozzle of the lipstick tube is circular, and the lips that need to be coated with lipstick are irregular curved surfaces, The lipstick core contained in the existing lipstick tube is often difficult to apply to the corners of the lips. Two, the mouth of the existing lipstick tube is a horizontal section, which does not conform to the shape of people's lips, and it is easy to scratch the lips during use. 3. When applying lipstick, the lipstick core is not stressed vertically downward, but obliquely sideways. When the lipstick core is stretched out too long, it is easy to break due to uneven force. The above-mentioned defects affect the user experience to a certain extent, which is an urgent problem to be solved in the lipstick manufacturing industry.

Utility model content

In order to overcome the defects of unreasonable nozzle structure design of existing lipstick tubes, the utility model discloses a lipstick tube. The adoption of the technical solution is convenient for users to apply, does not scratch the lips and prevents the lipstick core from being broken due to uneven force.

In order to achieve the above purpose, the following technical solutions are adopted:

A lipstick tube, comprising an outer tube and an inner tube that are nested with each other, the upper end of the outer tube is provided with a nozzle, and a lipstick core is fixed in the inner tube; the nozzle of the outer tube is a beveled arc surface , the arc surface is concave.

Preferably, the end surface of the lipstick core is a chamfered arc surface, and the arc surface is concave.

As an embodiment, the cross section of the outer tube is circular.

As an embodiment, the cross section of the outer tube is oval.

As an embodiment, the cross-section of the outer tube is oval-like.

Preferably, the outer tube has a side with a large curvature and a side with a small curvature, and the chamfered arc surface of the nozzle smoothly extends obliquely downward from the side with a large curvature to the side with a small curvature.

Preferably, the wall thickness of the outer tube gradually decreases from bottom to top.

Compared with the prior art, the utility model has the beneficial effects of:

In the technical solution, the nozzle of the lipstick tube and the end surface of the lipstick core are set as beveled arc surfaces, and the arc surfaces are concave. Consistent with the shape of human lips, the user can easily apply the lipstick tube to the corners of the lips with the lipstick tube of the technical solution, because when coating, the higher side of the mouth of the lipstick tube faces In addition, outward force during coating like this will not cause the lipstick core to break due to uneven force. And also does not scratch the lips.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The schematic implementation and description of the utility model are used to explain the utility model, but not as a limitation to the utility model.

Its specific technical solutions are:

As shown in Figures 1 and 2, a lipstick tube includes an outer tube 1 and an inner tube 2 that are nested in each other, the upper end of the outer tube 1 is provided with a nozzle 11, and a lipstick core is fixed in the inner tube 2 3. The mouth 11 of the outer tube 1 is a chamfered arc surface, and the arc surface is concave. The lipstick tube given in this embodiment is an improvement made on the basis of the existing lipstick tube. Usually, in order to ensure that the inner tube 2 can expand and contract smoothly and steadily in the outer tube 1, the shape of the tube body of the inner tube 2 and the outer tube 1 The same, and the outer wall of the inner tube 2 is attached to the inner wall of the outer tube 1 . In order to ensure that the lipstick core 3 can be firmly fixed in the inner tube 2, the profile of the lipstick core 3 is also designed according to the cavity shape of the inner tube 2. In order to protect the lipstick core 3, a cap 4 matching the outer tube is also provided.

The nozzle 11 is set so that the arc surface is exactly the same as the shape of human lips. When using it, the user only needs to rotate the lipstick core 3 to the nozzle 11 position of the outer tube, and then fit it on the lips. It can easily achieve one-time application of lipstick, without missing the corners of the lips, and without scratching the lips. However, using the lipstick tube of the prior art requires multiple modifications and fillings to ensure that the lipstick is completely applied to the lips. Therefore, using the lipstick tube of the present technical solution to coat the lips can save lip makeup time. One side of the nozzle 11 of the outer tube 1 described in the technical solution is high, while the other side is low. When the user applies lipstick, he will forcefully press the lipstick core 3 from the side, and the force-bearing side is just the side where the nozzle 11 of the outer tube is high, which greatly reduces the pressure on the lipstick core 3. The possibility of breaking, this advantage is more obvious when the lipstick core 3 is made of a softer material. Making the lipstick tube of the utility model saves more material than the lipstick tube of the prior art. The lipstick in the prior art cannot be used when the lipstick core is lower than the mouth of the nozzle, but the utility model can still be used normally when the lipstick core is lower than the mouth of the nozzle because the nozzle is an obliquely cut concave arc surface. . Therefore compared with the lipstick of the prior art, the lipstick core of the same amount is more durable with the lipstick tube of the utility model.

As shown in FIG. 1 , in order to improve the coating effect of the lipstick tube, the end surface of the lipstick core 3 is a chamfered arc surface, and the arc surface is concave. When the shape of the end face of the lipstick core 3 is also the same as that of the lips, the user can properly rotate the lipstick core 3 to exceed the height of the nozzle 11, and the technical effect of the technical solution can also be obtained. In this way, the user does not need to accurately align the nozzle 11 of the outer tube 1 with the end face of the lipstick core 3 during use, which is more convenient to use.

According to specific requirements, the shape of the outer tube 1 may be circular, elliptical or quasi-ellipse in cross section, among which quasi-ellipse is more suitable. As shown in Figure 3, for the outer tube 1 whose cross-section is quasi-elliptical, the outer tube 1 has a large curvature side 13 and a small curvature side 15, and the obliquely cut arc surface of the nozzle 11 is defined by the large curvature side 13 and the small curvature side 15. The curvature side 13 smoothly extends obliquely downward to the small curvature side 15 . The large curvature side 13 is more curved, while the small curvature side 15 is relatively gentle, and the higher end of the nozzle 11 is also relatively sharper, mainly to facilitate the user to finely outline the special parts of the lips.

As shown in FIG. 1 , in order to improve user experience, the wall thickness of the outer tube 1 decreases gradually from bottom to top. In this way, the lower part of the outer tube 1 is thicker and the upper part is thinner, which makes it easier for the user to hold the lipstick tube, and the overall appearance is more beautiful.

The technical solutions provided by the embodiments of the present invention have been introduced in detail above. In this paper, specific examples have been used to illustrate the principles and implementation methods of the embodiments of the present invention. The descriptions of the above embodiments are only applicable to help understand the present invention.
