Description

Technical Field

[0001] The present invention relates to the technical field of cosmetic packaging materials, and particularly to a cylindrical lipstick container.

Background Art

[0002] As shown in FIG. 7, most lipstick packaging containers include six components: a cap, a base, a main body, an inner tray, a rotating outer cover, and a bottom rotating mechanism. Among them, an annular groove is provided inside the main body, two vertical guide grooves are symmetrically provided on the rotating outer cover, two guide posts are symmetrically provided on the outer wall of the inner tray, the guide posts penetrate through the guide grooves and are placed in the annular groove, and both the annular groove and the guide grooves are used to realize the linear movement of the inner tray along the vertical guide grooves.

[0003] On the other hand, as environmental awareness becomes more and more popular, the more components there are, the more difficult it is to classify and reuse them. Moreover, the rotational contact of a product composed of six components is realized by the point contact or line contact between the guide posts and the annular groove, and an abnormal noise of "click" is likely to occur during rotation. In addition, the process of the inner tray of a product composed of six components rising is a way of rising while rotating, so the stability is insufficient.

Embodiments for Carrying Out the Invention

[0019] Hereinafter, the present invention will be described in more detail with reference to the drawings and specific embodiments so that the object, technical solution and advantages of the present invention will be more clearly understood. It should be understood that the specific embodiments described herein are merely for explaining the present invention and do not limit the present invention.

[0020] (Example 1) Referring to FIGS. 1 to 6, the technical solution of the cylindrical lipstick container provided by this embodiment includes the following components. A lid assembly 1, including a bottom lid 11 and an outer lid 12 provided above the bottom lid 11, and the outer lid 12 is detachably connected to the bottom lid 11. A bottom turning mechanism 2, the tail of the bottom turning mechanism 2 is provided in the bottom lid 11 and fixedly connected to the bottom lid 11, the head of the bottom turning mechanism 2 is provided in the cylindrical lipstick container body 3 and rotatably connected to the cylindrical lipstick container body 3, and a first turning part 21 is provided on the inner wall of the bottom turning mechanism 2. An inner dish 4, the tail (transmission section) of the inner dish 4 is placed in the bottom turning mechanism 2, the head (limiting section) of the inner dish 4 is placed in the cylindrical lipstick container body 3, the tail of the inner dish 4 is a second turning part 41 that fits the first turning part 21, and the first turning part 21 and the second turning part 41 cooperate to limit the inner dish 4 to move up and down. Since the bottom turning mechanism 2 is screw-connected to the transmission section of the tail of the inner dish 4, when the bottom turning mechanism 2 is rotated, the inner dish 4 is directly driven to move along the axis of the cylindrical lipstick container body 3. As shown in FIG. 7, it is not necessary to provide a turning outer cover part indicated by reference sign A. A limiting assembly 5, including a first limiting component 51 provided in the internal space of the cylindrical lipstick container body 3 and a second limiting component 52 provided at the head of the middle plate 4, wherein the first limiting component 51 and the second limiting component 52 cooperate to limit the middle plate 4 to move linearly.

[0021] In a specific embodiment, the outer lid 12 may be designed to be locked to the bottom lid 11. When the bottom lid and the outer lid are made of PP material, an annular boss that fits and locks into the groove at the bottom of the inner wall of the outer lid is provided around the entire circumference outside the uppermost part of the bottom lid. When the bottom lid and the outer lid are made of PET material, at least three circular bosses are provided along the circumference at the uppermost part of the bottom lid so as to fit and lock into the groove at the bottom of the inner wall of the outer lid to realize smooth removal of the lid.

[0022] In a specific embodiment, the bottom turning mechanism 2 is provided in the internal space of the bottom lid 11. The bottom end of the bottom turning mechanism 2 is fixedly locked to the bottom lid 11. There is a space between the upper half of the bottom turning mechanism 2 and the bottom lid 11 to accommodate the bottom of the cylindrical lipstick container body 3. The tail of the cylindrical lipstick container body 3 is placed in the gap between the bottom turning mechanism 2 and the bottom lid 11 and is rotatably locked to the bottom turning mechanism 2. The tail end of the middle plate 4 is rotatably provided in the internal space of the bottom turning mechanism 2, and the uppermost part of the middle plate 4 is placed in the internal space of the cylindrical lipstick container body 3.

[0023] Preferably, the connection between the bottom turning mechanism 2 and the bottom lid 11 is designed as follows. A plurality of vertical third limiting grooves 111 are provided around the bottom of the inner wall of the bottom lid 11. Above the third limiting grooves 111 on the inner wall of the bottom lid 11, a fourth limiting groove 112 is provided around the entire circumference. A vertical first limiting boss 22 is provided at the position corresponding to the third limiting groove 111 at the tail of the bottom turning mechanism 2, and a fourth annular boss 23 is provided around the position corresponding to the fourth limiting groove 112 on the bottom turning mechanism 2. The first limiting boss 22 of the bottom turning mechanism 2 is locked in the third limiting groove 111 and is used to limit the bottom turning mechanism 2 to rotate relative to the bottom cover 11. The fourth annular boss 23 of the bottom turning mechanism 2 is placed in the fourth limiting groove 112 of the bottom cover 11 and is used to fix the bottom turning mechanism 2 and avoid the separation of the bottom turning mechanism 2 and the bottom cover 11 in the vertical direction when in use. In this structure, when the bottom cover 11 is rotated, the bottom cover 11 drives the bottom turning mechanism 2 to rotate.

[0024] Preferably, the connection method between the cylindrical lipstick container body 3 and the bottom turning mechanism 2 is as follows. Above the fourth annular boss 23 of the bottom turning mechanism 2, a fifth annular boss 24 and a third annular boss 25 are provided in this order at intervals from bottom to top. The gap between the fifth annular boss 24 and the third annular boss 25 is the second limiting groove 26. A first limiting groove 31 is peripherally provided at the position corresponding to the third annular boss 25 at the bottom of the inner wall of the cylindrical lipstick container body 3. The region between the first limiting groove 31 and the bottom surface of the cylindrical lipstick container body 3 is formed as a second annular boss 32 that fits the second limiting groove 26. The third annular boss 25 of the bottom turning mechanism 2 is located in the first limiting groove 31 of the cylindrical lipstick container body 3, and the second annular boss 32 of the cylindrical lipstick container body 3 is located in the second limiting groove 26 of the bottom turning mechanism 2.

[0025] Preferably, the connection method between the middle tray 4 and the bottom turning mechanism 2 is as follows. A first annular boss is provided obliquely at the uppermost part of the inner wall of the bottom turning mechanism 2. The first annular boss is the first turning part 21. The tail of the middle tray 4 is a threaded rod. The threaded rod is the second turning part 41. The threaded turning angle of the threaded rod matches the inclination angle of the first annular boss. The depth of the thread of the threaded rod matches the thickness of the first annular boss. When actually in use, according to needs, the number and arrangement position of the first annular bosses can be set based on the helix of the threaded rod. When installing, the first annular boss is located in the groove between the threads of the threaded rod (the second turning part 41), and the first annular boss and the external thread of the threaded rod are screwed and transmitted. The actual transmission effect is similar to that of a ball screw fixed with a nut.

[0026] Preferably, the region for accommodating the middle plate 4 that is displaced vertically within the internal space of the cylindrical lipstick container body 3 is the first region 33. The first region 33 is in the form of a regular polygonal prism. The inner wall connected to the first region 33 of the cylindrical lipstick container body 3 is the first limiting component 51. The shape of the head of the middle plate 4 is in the form of a regular polygonal prism that conforms to the first region 33. The outer wall of the head of the middle plate 4 is the second limiting component 52. It is precisely because the first region 33 and the head of the middle plate 4 are in the form of a regular polygonal prism that the inner wall of the cylindrical lipstick container body 3 closely adheres to and restricts the head of the middle plate 4, and the middle plate 4 is prevented from rotating with respect to the cylindrical lipstick container body 3. Therefore, when the bottom rotation mechanism 2 rotates and drives, the middle plate 4 can only move stably and linearly up and down along the cylindrical lipstick container body 3. Moreover, in this design, since the form of the regular polygonal prism inside the cylindrical lipstick container body 3 is formed by cutting, the gap between the middle plate 4 and the inner wall of the cylindrical lipstick container is reduced, the stability is improved, and the head of the cylindrical lipstick container body 3 and the middle plate 4 actually correspond to a regular polygonal slot and a regular polygonal block.

[0027] Preferably, in this design, the thickness of the inclined mouth part at the uppermost part of the cylindrical lipstick container body 3 is increased. The wall thickness range of the cylindrical lipstick container body is 1 mm to 1.2 mm. At the uppermost part of the cylindrical lipstick container body, an arc of radius R is provided to make a transitional connection to the side wall, thereby reducing sharp parts and improving the safety of the product.

[0028] Preferably, the first region 33 of the cylindrical lipstick container body 3 does not communicate directly with the uppermost part of the cylindrical lipstick container body 3 and is at a certain distance from the uppermost part of the cylindrical lipstick container body 3. The region between the uppermost part of the cylindrical lipstick container body 3 and the first region 33 is the second region 34. The inner diameter of the second region 34 is smaller than the inner diameter of the first region 33. Since the outer diameter of the first region 33 conforms to the outer diameter of the head of the middle plate 4, the inner diameter of the second region 34 is smaller than the outer diameter of the head of the middle plate 4. That is, the cross-section of the head of the lipstick partially overlaps with the middle plate. That is, it is equivalent to adding a limiting surface below the second region 34. When the middle plate 4 rises to the uppermost part, it is prevented from disengaging from the thread and idling, and a blocking force is applied from above.

[0029] The operating principle or process of the cylindrical lipstick container provided by the present invention is as follows. As Method 1, remove the outer lid 12, firmly hold the cylindrical lipstick container body 3, and rotate the bottom lid 11 in the forward direction. The first limiting boss 22 on the bottom turning mechanism 2 receives the forward driving force of the third limiting groove 111 of the bottom lid 11, and the bottom turning mechanism 2 rotates in the forward direction. Since the bottom turning mechanism 2 is screwed to the transmission section of the middle dish 4, the middle dish 4 attempts to rise along the reverse helix. At this time, the first limiting component 51 in the cylindrical lipstick container body 3 applies a forward limiting force to the second limiting component 52 on the outer wall of the limiting section of the middle dish 4, and the middle dish 4 moves linearly upward along the axis of the cylindrical lipstick container body 3. Similarly, rotate the bottom lid 11 in the reverse direction. The first limiting boss 22 on the bottom turning mechanism 2 receives the reverse driving force of the third limiting groove 111 of the bottom lid 11, and the bottom turning mechanism 2 rotates in the reverse direction. Since the bottom turning mechanism 2 is screwed to the transmission section of the middle dish 4, the middle dish 4 attempts to descend along the forward helix. At this time, the first limiting component 51 in the cylindrical lipstick container body 3 applies a reverse limiting force to the second limiting component 52 on the outer wall of the limiting section of the middle dish 4, and the middle dish 4 moves linearly downward along the axis of the cylindrical lipstick container body 3.

[0030] As Method 2, remove the outer lid 12, firmly hold the bottom lid 11, and rotate the cylindrical lipstick container body 3 in the reverse direction. The first limiting component 51 of the cylindrical lipstick container body 3 applies a reverse driving force to the second limiting component 52 of the middle dish 4, and the middle dish 4 screwed to the bottom turning mechanism 2 rises along the reverse helix under the action of the reverse driving force. Similarly, rotate the cylindrical lipstick container body 3 in the forward direction. The first limiting component 51 of the cylindrical lipstick container body 3 applies a forward driving force to the second limiting component 52 of the middle dish 4, and the middle dish 4 screwed to the bottom turning mechanism 2 descends along the forward helix under the action of the forward driving force.

[0031] Note that the above is only a preferred embodiment of the present invention and does not limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still change the technical solutions described in the above embodiments or equivalently replace some of their technical features. Without departing from the spirit and principle of the present invention, any changes, equivalent replacements, improvements, etc. shall be included in the protection scope of the present invention.
