[0046] Reference Figures 1-3 , an embodiment of the present application provides a lipstick container, which is beneficial to improving the sealing effect of the cover 200, so as to better maintain the freshness and durability of the lipstick cosmetic, and reduce cracking or spilling caused by insufficient sealing. The lipstick container includes an outer cylinder 100 and a cover 200. The outer cylinder 100 includes an insertion cover end 110 and an inner cavity. The insertion cover end 110 has a first opening communicating with the inner cavity. The inner cavity is used for carrying the lipstick cosmetic. The outer peripheral wall of the insertion cover end 110 is annularly provided with a first sealing structure 120 and a second sealing structure 300. The first sealing structure 120 and the second sealing structure 300 are arranged at intervals along the opening direction X of the first opening; the inner peripheral wall of the cover 200 is annularly provided with a third sealing structure 210 and a fourth sealing structure 220. The third sealing structure 210 and the fourth sealing structure 220 are arranged at intervals along the opening direction X; wherein, the cover 200 is detachably sealed on the insertion cover end 110, and the first sealing structure 120 and the third sealing structure 210 are in sealing cooperation, and the second sealing structure 300 and the fourth sealing structure 220 are in sealing cooperation.

[0047] The outer peripheral wall of the plug end 110 of the lipstick container according to the embodiments of the present application is provided with a first sealing structure 120 and a second sealing structure 300 in a circumferential manner. The inner peripheral wall of the cover body 200 is provided with a third sealing structure 210 and a fourth sealing structure 220 in a circumferential manner. The first sealing structure 120 and the third sealing structure 210 are in sealing cooperation, and the second sealing structure 300 and the fourth sealing structure 220 are in sealing cooperation. That is, a multi-stage sealing cooperation structure is designed, which is beneficial to improving the sealing effect of the cover body 200, so as to better maintain the freshness and persistence of the lipstick cosmetic, and reduce cracking or overflow caused by insufficient sealing.

[0048] In some embodiments, referring to Figures 1-3 , the first sealing structure 120 is formed at the first edge of the outer peripheral wall close to the first opening, and the third sealing structure 210 is in sealing fit with the first sealing structure 120; the second sealing structure 300 is a sealing ring, the sealing ring is sleeved on the outer peripheral wall of the plug end 110, and is in interference fit with the inner peripheral wall of the cover body 200. The fourth sealing structure 220 is a stepped structure formed by surrounding the inner peripheral wall, and the stepped structure is in interference sealing fit with the sealing ring. The first sealing structure 120 is formed at the first edge of the outer peripheral wall close to the first opening, which can form a first-stage seal at the first edge first, achieving an early sealing and blocking effect, and reducing the overflow of the lipstick cosmetic and flowing into the space between the outer peripheral wall of the plug end 110 and the inner peripheral wall of the cover body 200 as early as possible. Then, a second-stage seal is formed through the cooperation of the second sealing structure 300 and the fourth sealing structure 220. The second sealing structure 300 is a sealing ring, the sealing ring is sleeved on the outer peripheral wall of the plug end 110, and is in interference fit with the inner peripheral wall of the cover body 200. Furthermore, a third-stage seal or another-stage seal is formed by using the sealing ring, so that the sealing effect is further improved.

[0049] In some embodiments, referring to Figures 2-4 , an annular receiving groove 140 is formed on the outer peripheral wall of the plug end 110, and the sealing ring is sleeved in the annular receiving groove 140, which is beneficial to fixing the position of the sealing ring and preventing it from falling off easily.

[0050] Furthermore, in some embodiments, the cross-sectional shape of the annular receiving groove 140 is a square notch, and the cross-sectional shape of the sealing ring includes a square cross-sectional part filled in the square notch and a convex circular cross-sectional part protruding from the annular receiving groove 140. The cross-sectional shape of the sealing ring formed by the convex circular cross-sectional part and the square cross-sectional part can be more stably assembled in the annular receiving groove 140.

[0051] Furthermore, in some embodiments, the surface of the sealing ring has wavy lines for increasing friction. By designing the surface of the sealing ring in a concave-convex wavy pattern, the friction can be increased and the sealing effect can be improved.

[0052] Referring to Figures 2-4, in some embodiments, along the opening direction X of the first opening, the sealing ring is located on the side of the first sealing structure 120 away from the first opening. Then, after the first sealing structure 120 and the third sealing structure 210 form a first-level sealing fit, a first-level seal is further formed on the side of the first sealing structure 120 away from the first opening through the sealing of the fourth sealing structure 220 and the sealing ring, which can better reduce the overflow of the lipstick cosmetic.

[0053] Reference Figures 2-4 , in some embodiments, the fourth sealing structure 220 is a stepped structure formed by surrounding the inner peripheral wall. The stepped structure includes a first stepped sub-part 221 and a second stepped sub-part 222. The first stepped sub-part 221 is formed by surrounding and opening on the inner peripheral wall of the cover body 200, and the first stepped sub-part 221 is in a stepped shape; the second stepped sub-part 222 is formed by surrounding and opening on the inner peripheral wall of the cover body 200, and is in a stepped shape connected to the first stepped sub-part 221 and is located on the side of the first stepped sub-part 221 close to the inside of the cover body 200; wherein, at least part of the stepped surface of the first stepped sub-part 221 and at least part of the second stepped sub-part 222 are respectively in sealing fit with the second sealing structure 300. Then, a sealing interference fit is formed at two parts respectively, that is, combined with the sealing fit of the third sealing structure 210 and the first sealing structure 120, a three-stage sealing structure is formed.

[0054] Reference Figures 1-3 , in some embodiments, the first sealing structure 120 is a first annular surface around the first edge, and the third sealing structure 210 is a second annular surface around the inner peripheral wall. The first annular surface and the second annular surface are in sealing fit. The first-level seal is realized by the sealing fit of the first annular surface and the second annular surface. The structure is simple, the cost is low, and it is easy to implement.

[0055] Reference Figures 1-3 , in some embodiments, along the opening direction X of the first opening, the dimension of the sealing fit between the first annular surface and the second annular surface is not less than 2 mm. The dimension of the sealing fit along the opening direction X of the first opening should not be too small to maintain the sealing effect of the first-level seal and reduce the premature sealing failure when the cover body 200 slides away from the plugging end 110 relatively.

[0056] In some embodiments, reference Figures 1-3 , in some embodiments, the inner diameter of the inner hole formed by surrounding the third sealing structure 210 is smaller than the minimum inner diameter of the inner hole formed by surrounding the fourth sealing structure 220. Since the third sealing structure 210 is relatively farther from the opening end of the cover body 200, this design structure is similar to the structure of a stepped hole formed, which can more conveniently realize the sleeving of the cover body 200 on the plugging end 110 of the outer cylinder 100.

[0057] In some embodiments, referenceFigures 1-3 The outer diameter of the first sealing structure 120 is equal to the inner diameter of the inner hole formed by surrounding the third sealing structure 210. Here, the equality can include an appropriate interference fit, thereby achieving a sealed fit; the maximum outer diameter of the second sealing structure 300 is greater than the inner diameter of the inner hole formed by surrounding the third sealing structure 210 and less than the maximum inner diameter of the inner hole formed by surrounding the fourth sealing structure 220, which can more conveniently achieve the sleeving of the cover body 200 on the plugging end 110 of the outer cylinder 100, and is beneficial to achieving a sealed fit between the second sealing structure 300 and the fourth sealing structure 220.

[0058] In some embodiments, the lipstick container further includes an elliptical bead-shaped convex structure 130 and an annular groove structure 230. The elliptical bead-shaped convex structure 130 is convexly provided around the periphery of the outer wall; the annular groove structure 230 is recessed around the inner wall. The elliptical bead-shaped convex structure 130 and the annular groove structure 230 are in snap-fit and limiting cooperation. In some embodiments, in the circumferential direction of the inner wall, the annular groove structure 230 and the elliptical bead-shaped convex structure 130 are in sealed fit. In addition to the elliptical bead-shaped convex structure 130 and the annular groove structure 230 cooperating with each other to play a role in moving limit, to prevent the cover body 200 from sliding relative to the plugging end 110 and playing a more stable capping role; a certain sealing effect is also achieved through the sealed fit. Among them, the inner wall of the cover body 200 refers to the inner wall of the side seal of the cover body 200, and the side seal surrounds the top seal of the cover body 200 to form the structure of the cover body 200.

[0059] In some embodiments, the position where the elliptical bead-shaped convex structure 130 and the annular groove structure 230 are in snap-fit and limiting cooperation is located between the first sealing structure 120 and the second sealing structure 300. In addition to playing a role in snap-fastening and limiting to prevent the cover body 200 from falling off. Combining that the annular groove structure 230 and the elliptical bead-shaped convex structure 130 are in sealed fit in the circumferential direction of the inner wall, it is equivalent to forming another sealed fit structure between the first sealing structure 120 and the second sealing structure 300.

[0060] Reference Figures 1-3 In some embodiments, the outer surface of the elliptical bead-shaped convex structure 130 is a convex curved surface, and the convex curved surface is smoothly connected to the surface of the outer wall. The inner surface of the annular groove structure 230 is a concave curved surface, and the concave curved surface is smoothly connected to the surface of the inner wall. The smooth connection is not likely to get stuck, and the loading and unloading of the cover body 200 are smoother.

[0061] In some embodiments, reference Figures 2-4 The lipstick container further includes an inner cylinder assembly 400. The inner cylinder assembly 400 is inserted into the inner cavity. The inner cylinder assembly 400 is provided with a receiving groove for carrying the lipstick cosmetic. The inner cylinder assembly 400 can adopt an existing structure, and will not be elaborated here.

[0062] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0063] The above embodiments only express one implementation manner of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
