Description

Technical Field

[0001] This invention relates to ointment cosmetic tubes, specifically a square solid ointment cosmetic tube. Background Technology

[0002] Cosmetic tubes refer to containers used to store cosmetic creams, such as lipsticks, eyebrow pencils, sunscreens, deodorants, and snake oil creams, in either cream or stick form. Examples of such products include Chinese patent application number 201720438547.9, authorized on December 19, 2017, entitled "A Twist-Type Anti-Slipping Lipstick Tube"; and another example is Chinese patent application number 201520284043.7, authorized on September 30, 2015, entitled "Three-in-One Cosmetic Pen." However, square-shaped shapes are relatively rare in these products and other similar products. Such cosmetic containers, including square-shaped creams or brushes, are exemplified by Chinese patent application number 201180042722.8, published on May 1, 2013, entitled "Rotary Opening and Closing Type Brush Tube-Shaped Cosmetic Container." This container offers several advantages: cosmetics can be easily opened and closed by simply rotating the cap; leakage is prevented even if the container is accidentally pressurized during use or storage; the spiral groove shape ensures the sealing cap and rotating cap are firmly fixed at the maximum rising / falling position; and the rising / falling motion is gentle. However, the aforementioned product and similar products have complex structural designs, are inconvenient to assemble, have high production costs, poor directional rotation effect, and a limited range of directional rotation angles. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a square solid ointment cosmetic tube that solves the technical problems of existing similar products having complex structural designs, inconvenient assembly, high production costs, poor directional rotation effects, and limited directional rotation angles. This objective is achieved through the following technical solution.

[0004] A square solid ointment cosmetic tube has an ointment body disposed in an ointment groove at the top of a bead base. A screw at the bottom of the bead base extends into a screw hole in a fork seat inside the base through a rotating ointment shell. The outer diameter of the fork seat is confined within the base. The ointment shell and the bead base are integrated. An outer cover is provided on the outer diameter of the seat opening at the top plane of the base. The base, bead base, and fork seat constitute a spiral lifting ointment core assembly. The spiral lifting ointment core assembly is fixedly disposed within the base. The top and bottom of the screw of the ointment shell are fastened and fixed to a fixing hole at the top plane of the base. The bottom of the ointment shell is disposed at the top of the base. The rotation of the spiral lifting ointment core assembly drives the bead seat inside the ointment shell to move up and down. The base, ointment shell, ointment body, and ointment groove of the bead seat are respectively cuboids with rounded chamfered corners. The key structural design features a downward-protruding center at the bottom of the grease shell, which fits into the inner fork sleeve of the base. The grease shell and the fork sleeve are integrated. The outer diameter of the fork sleeve has an equilateral prism with rounded chamfers. The two ends of the prism's outer diameter are symmetrically angled and fixed to a fixed head at one end of the elastic element inside the base. The other end of the elastic element is abutted against the inner wall of the base via a spring or an elastic head. Thus, when the grease shell rotates, the outer hexagonal prism at the bottom of the grease shell causes the fork sleeve at its outer diameter to rotate as well. The prism's outer diameter at the rounded chamfer pushes the elastic element to deform. Only when the fork sleeve disengages from the fixed head at one end of the elastic element can the grease shell rotate a certain angle. The screw hole of the fork seat has internal threads or threads.

[0005] The hexagonal prism protruding downwards from the center of the bottom of the grease case fits into the hexagonal hole of the inner fork sleeve of the base. The grease case and the fork sleeve are connected as one unit through the hexagonal prism of the grease case and the inner hexagonal hole of the fork sleeve. The way the hexagonal prism of the grease case and the inner hexagonal hole of the fork sleeve fit together is not limited to a hexagonal structure. It can also adopt a square structure or a prismatic structure, as long as the grease case and the fork sleeve are connected as one unit.

[0006] The outer diameter of the fork sleeve is a square with rounded corners at both ends. The two ends of the square outer diameter of the fork sleeve are symmetrically inclined and fixed to the fixing head at one end of the elastic element inside the base. Thus, the rotation angle of the fork sleeve in one rotation is 90 degrees.

[0007] The fixed head of the elastic element has an "M" or "V" shape at one end. The elastic element is a spring seat or a spring plate. The spring at the other end of the spring seat is located in a spring groove on the inner wall of the bottom of the first base. The elastic head at the other end of the spring plate is inserted into the inner wall of the bottom of the second base or into the insertion groove of the insertion post. The fixed head of the elastic element is not limited to the "M" or "V" shaped design. For example, the fixed head of the elastic element can be symmetrically wave-shaped on both sides, or it can be shaped like a "7", "Z", "S", or "J". As long as the middle of the fixed head of the elastic element is fixed to the square outer diameter of the fork sleeve, and the fixed head of the elastic element is further fixed to the inner wall of the bottom of the base, it is acceptable.

[0008] The outer diameter of one end of the fixed head of the elastic element slides against the inner wall of the base, or engages with a protruding post on the inner wall of the base. This structure further improves the stability of the elastic element sliding against the inner bottom wall of the base.

[0009] The central hole inside the screw of the ball seat communicates with the center of the bottom of the paste tank, and a sealing ring is provided at the fastening and fixing point between the bottom of the paste shell and the top of the base. The above structure improves the internal airtightness and ventilation.

[0010] The screw hole of the fork seat inside the base is located inside a circular column with one protruding end. The circular column of the fork seat fits into the cylindrical hole at the bottom of the outer hexagonal column of the grease shell. The other end of the fork seat has a square outer diameter and is confined within the base. This structure has a small overall size and a long travel distance.

[0011] The circular cylindrical screw hole at the top of the fork seat is located inside the fork seat, and the screw of the ball seat is located on the circular boss protruding at the bottom. The circular boss of the ball seat fits into the cylindrical hole at the bottom of the outer hexagonal column of the grease shell.

[0012] The bottom opening of the base fits into the top opening of the bottom shell, and the outer cover is integrally formed with the outer diameter of the bottom shell to create a cuboid shape. The bottom shell can be provided as needed, or it can be replaced with a bottom cover at the bottom opening of the base.

[0013] The base, cream shell, cream body, and the cream groove of the bead holder are all cubes with rounded chamfers at their ends. The cream groove of the bead holder is square or circular, and the length of the symmetrical oblique angle at both ends of the fork sleeve is less than the width of the fork holder. The above is an embodiment of the square structure of this cosmetic tube, and the cream body adopts a corresponding square or cylindrical shape.

[0014] The present invention has a reasonable structural design, is easy to assemble and use, and has low production cost. The directional rotation angle is determined by the prismatic edge of the outer diameter of the fork sleeve. Only the size of the corresponding component needs to be controlled. The overall shape can be rectangular or square. It is mainly used as a square solid ointment cosmetic tube and is a structural improvement of similar products. Attached Figure Description

Detailed Implementation

[0030] The structure of the present invention will now be further described with reference to the accompanying drawings. For example... Figures 1-13As shown, the cream in the cosmetic tube is placed in the cream groove at the top of the bead seat 4. The screw 401 at the bottom of the bead seat extends into the screw hole 901 of the fork seat 9 inside the base through the rotation of the cream shell 3. The outer diameter of the fork seat is confined within the base. The cream shell and the bead seat are integrated. An outer cover 5 is provided on the outer diameter of the seat opening at the top plane of the base. The base, bead seat, and fork seat constitute a spiral lifting cream core assembly. The spiral lifting cream core assembly is fixedly installed inside the base. The top and bottom of the screw of the cream shell are fastened and fixed to the fixing hole at the top plane of the base. The bottom of the cream shell is located at the top of the base. The spiral lifting core assembly rotates to move the bead seat inside the cream shell up and down. The base, cream shell, cream body, and bead seat groove are respectively cuboids with rounded corners at the ends. The hexagonal prism 301 with the bottom center of the cream shell protruding downwards is fitted into the hexagonal hole 801 of the inner fork sleeve 8 of the base. The cream shell and the fork sleeve are connected as one body. The outer diameter of the fork sleeve is a square with rounded corners. The two ends of the square outer diameter of the fork sleeve are symmetrically abutted and fixed to the fixing head at one end of the elastic element inside the base. The other end of the elastic element abuts against the inner wall of the base through the spring 6 or the elastic head.

[0031] like Figures 1-8 In the first embodiment shown, the base is a first base 2, and the elastic element is a spring seat 7. One end of the fixed head of the spring seat is "M"-shaped, and the spring 6 at the other end of the spring seat is set in the spring groove 201 on the inner wall of the bottom of the first base. The spring is inserted into the spring post of the spring seat, and the outer diameter of one end of the fixed head of the spring seat slides against the inner wall of the bottom of the base. At the same time, the central hole 402 of the screw of the ball seat communicates with the center of the bottom of the paste groove, and a sealing ring 12 is provided at the fastening and fixing point between the bottom of the paste shell and the top of the base. The screw hole of the fork seat in the base is set in a circular column with one protruding end. The circular column of the fork seat fits into the cylindrical hole at the bottom of the outer hexagonal column of the paste shell. The outer diameter of the other end of the fork seat is square and is confined within the base. The bottom seat opening of the base fits into the shell opening at the top of the bottom shell, and the outer cover and the outer diameter of the bottom shell are integrally formed into a cuboid.

[0032] Based on the structural features of the above embodiment one, such as Figures 9-13 In the second embodiment shown, the base is a second base 10, the elastic element is a spring sheet 11, one end of the fixing head of the spring sheet is also "M" shaped, and the other end of the elastic head of the spring sheet is inserted into the inner wall of the bottom of the second base or the insertion slot 1001 of the insertion post. The outer diameter of one end of the fixing head of the spring sheet abuts against the protruding post limiting position on the inner wall of the base. Figure 14 As shown, based on Embodiment 1, the circular cylindrical screw hole at the top of the fork seat is located inside the fork seat, and the screw of the ball seat is located on the circular boss protruding at the bottom. The circular boss of the ball seat fits into the cylindrical hole at the bottom of the outer hexagonal column of the grease shell. The outer diameter of the fork sleeve is an elliptical square with rounded corners, or it can adopt the square structure design with rounded corners of the fork sleeve in Embodiment 1.

[0033] When using, open the outer cover, rotate the paste shell or the bottom shell until the bottom shell and paste shell are rotated to a 90-degree angle and stop, and the solid paste in the bead holder will extend out of the paste shell; continue to rotate the paste shell or the bottom shell until the bottom shell and paste shell are aligned and stop, and the solid paste in the bead holder will continue to extend out of the paste shell; repeat the above rotation operation, and the solid paste in the bead holder will continue to extend out of the paste shell; reverse the above operation, and the solid paste will retract into the paste shell.
