Description

Technical Field

[0001] This invention relates to ointment cosmetic tubes, specifically bottom-rotating packaging bottles for solid sunscreen sticks or deodorants. Background Technology

[0002] Cosmetic tubes refer to containers used to store cosmetic pastes, such as lipsticks, eyebrow pencils, sunscreens, body balms, and snake oil creams, in either paste or stick form. Some of these are square-shaped cosmetic containers or brush-shaped containers, such as Chinese patent application number 201180042722.8, published on May 1, 2013, entitled "Rotary Opening and Closing Type Brush Tube-Shaped Cosmetic Container." This rotary opening and closing type brush tube-shaped cosmetic container has the following advantages: cosmetics can be easily opened / closed by simply rotating the cap; it prevents leakage in the event of accidental pressurization during use or storage; based on the shape of the spiral groove, the sealing cap and rotating cap are firmly fixed at the maximum rising / falling position; and it allows for gentle movement during the rising / falling motion. However, the above-mentioned product and similar products have relatively 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 shortcomings, the purpose of this invention is to provide a bottom-rotating packaging bottle for solid sunscreen sticks or deodorants, thereby solving the technical problems of existing similar products, such as complex structural design, inconvenient assembly, high production cost, poor directional rotation effect, limited directional rotation angle, and particularly inadequate spring plate structure design. This objective is achieved through the following technical solution.

[0004] A bottom-rotating packaging bottle for solid sunscreen sticks or deodorants, wherein the paste is disposed in a paste groove at the top of a bead holder, and a screw at the bottom of the bead holder extends into the screw hole of a fork holder inside the base through the rotation of the paste shell. The outer diameter of the fork holder is confined within the base, and the paste shell and the bead holder are integrated. The bead holder is confined within the paste shell and moves up and down through the interaction of the screw and the screw hole of the fork holder. An outer cover is provided on the outer diameter of the seat opening at the top plane of the base, and the outer cover is engaged with the upper outer diameter of an inner cover extending into the base. The lower outer diameter of the inner cover is fitted and fixedly disposed within the base. The base, fork holder, inner cover, paste shell, and bead holder are connected in sequence. The base, fork holder, inner cover, paste shell, bead holder, and the paste groove of the bead holder are respectively cuboids with rounded chamfered corners. The key structural design features a downward-protruding center at the bottom of the ointment shell, which is fitted into the inner cover via a positioning shaft. The ointment shell and the positioning shaft are integrated. The outer diameter of the positioning shaft has an equilateral prism with rounded chamfers. The two ends of the prism's outer diameter are symmetrically angled and fixed to a fixing head at the V-shaped opening of one end of the spring plate inside the inner cover. The other end of the spring plate abuts against the inner wall of the inner cover via an elastic head. The spring plate is fixedly installed inside the inner cover, and the bottom plane of the ointment shell rotates against the top plane of the inner cover.

[0005] The hexagonal prism protruding downwards from the center of the bottom of the grease shell fits into the hexagonal hole at the top of the positioning shaft inside the base. The grease shell and the positioning shaft are thus connected as one unit through the hexagonal prism of the grease shell and the hexagonal hole of the positioning shaft. The way the hexagonal prism of the grease shell fits into the hexagonal hole of the positioning shaft is not limited to a hexagonal structure; it can also adopt a square or prismatic structure, as long as the grease shell and the positioning shaft are connected as one unit. Thus, when the grease shell drives the inner bead seat to rotate, the hexagonal prism at the bottom of the grease shell drives the positioning shaft at the outer diameter of the hexagonal prism to rotate together. The prismatic outer diameter at the chamfered corner of the outer diameter of the positioning shaft pushes the spring plate to deform, and the grease shell can only rotate a certain angle when the positioning shaft is released from the fixing head at one end of the spring plate.

[0006] The bottom outer diameter of the positioning shaft is a square with rounded corners at both ends. The two ends of the square outer diameter of the positioning shaft are symmetrically abutted and fixed to the fixing head at the V-shaped opening of the inner spring plate inside the inner cover. Thus, the rotation angle of the positioning shaft is 90 degrees. The outer diameter of the positioning shaft is not limited to a square structure, as long as the fixing head at the V-shaped opening of the spring plate is abutted and positioned.

[0007] The outer diameter of the hexagonal socket at the top of the positioning shaft is larger than the square edge at the bottom. Simultaneously, the diagonal corners of the square at the bottom of the positioning shaft are aligned with the outer diameter of the hexagonal socket at the top. A transition edge is provided between the square edge at the bottom of the positioning shaft and the bottom of the outer diameter of the hexagonal socket at the top. The above is one structural embodiment of the positioning shaft. Another structural embodiment can be achieved by directly setting the hexagonal socket within the square outer diameter of the positioning shaft.

[0008] The spring sheet is a symmetrically stamped and bent metal elastomer, shaped like a "Y". One end of the fixed head of the spring sheet has a V-shaped opening with rear rolled edges on both sides, and the other end of the symmetrical elastic head has a protruding curled head. The curled heads of the spring sheets on both sides of the bottom of the inner cover are respectively snapped into the end grooves of the bottom of the inner cover. Simultaneously, the rear rolled edges of the spring sheets abut against the inner wall of the arc-shaped ribs at the bottom reinforcing ribs of the inner cover. The arc-shaped ribs on both sides of the bottom of the inner cover connect with the inner wall of the bottom of the inner cover to form a circular groove. The above is a specific structural embodiment of a spring sheet. This spring sheet structure is easy to manufacture, has good elasticity, and is easy to install and remove.

[0009] The spring sheet has a through hole at its center at the curling head, and a positioning post is located in the middle of the end groove at the bottom of the inner cover. The through hole of the spring sheet is inserted into the positioning post of the inner cover. This structure further improves the stability of the spring sheet in the inner cover.

[0010] The central hole inside the screw of the ball seat communicates with the center of the bottom of the paste tank, and a sealing rubber ring is provided at the connection point between the bottom of the paste shell and the top opening of the inner cover. This structure improves internal airtightness and ventilation.

[0011] The fork holder has a T-shaped intermediate sleeve at the screw hole and an integral support body at the bottom. The inner wall of the screw hole within the fork holder has internal threads or teeth. The sleeve extends into the grease box via a positioning shaft and is located below the bottom of the ball bearing within the grease box. Symmetrically arranged ribs are provided at the top opening of the screw hole. An airtight groove is provided at the bottom support body of the sleeve. The support body is fastened and fixed to the bottom of the base or the bottom of the inner cover within the base. The base and the fork holder are integrated, or the inner cover and the fork holder are integrated. Whether there is a gap between the bottom of the ball bearing within the grease box and the bottom of the grease box is irrelevant; it can be set as needed. The sleeve portion of the fork holder can also extend into the positioning shaft, but the screw stroke length at the bottom of the ball bearing will be shorter.

[0012] The top of the ointment shell has a cap at the opening, and the bottom of the cap is sealed and fixed to the top opening of the ointment shell. This packaging bottle has two ointment filling methods: the cap is required when filling the ointment from the bottom, and it is not required when filling the ointment from the top. At the same time, even if the cap is not used for ointment filling, it can also be used as a further protective structure for the ointment. The ointment can be opened by rotating after opening the outer cap and the cap, or the cap can be placed inside the outer cap for easy opening when the cap and the outer cap are used as one piece.

[0013] The base and inner cover are integrally injection molded to form a base, and a bottom cover is provided at the bottom opening of the base. Another embodiment omitting the inner cover, in which the above components are assembled using a base as the base and a bottom cover, is also described.

[0014] The base, fork, inner cap, cream shell, bead holder, 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 positioning shaft is less than the width of the fork holder. The above is an embodiment of the square structure of the packaging bottle, and the cream body adopts the corresponding square or cylindrical shape.

[0015] The present invention has a reasonable structural design, is easy to assemble and use, has low production cost, and is easy to adjust and change in terms of directional rotation angle and size. The overall shape can be rectangular or square. It is mainly used as a bottom rotating packaging bottle for solid sunscreen sticks or deodorants, and is a structural improvement of similar products.

The base, fork seat, inner cover, ointment shell, bead seat, and the ointment groove of the bead seat are respectively provided with cuboids with rounded corners at the end. The bottom center of the aforementioned ointment shell protrudes downwards and is fitted into the inner cover via the inner cover, thus connecting the ointment shell and the positioning shaft as a single unit. The outer diameter of the positioning shaft is provided with an equilateral prism with rounded chamfers. The two ends of the outer diameter of the prism of the positioning shaft are symmetrically abutted and fixed to the fixing head at the V-shaped opening of one end of the inner cover's spring plate 9. The other end of the spring plate abuts against the inner wall of the inner cover via an elastic head. The spring plate is fixedly installed inside the inner cover, and the bottom plane of the ointment shell rotates against the top plane of the inner cover. The hexagonal prism 501 protruding downwards from the bottom center of the ointment shell fits into the internal hexagonal hole 801 in the top opening of the positioning shaft 8 in the base. The ointment shell and the positioning shaft are connected as a single unit through the external hexagonal prism of the ointment shell and the internal hexagonal hole of the positioning shaft. At the same time, the bottom outer diameter of the positioning shaft is a square with rounded chamfers at both ends, and the two ends of the square outer diameter of the positioning shaft are symmetrically abutted and fixed to the fixing head at the V-shaped opening of one end of the inner cover's spring plate. The outer diameter of the hexagonal socket at the top of the positioning shaft is larger than the square edge at the bottom. At the same time, the diagonal corners of the square at the bottom of the positioning shaft are aligned with the outer diameter of the hexagonal socket at the top of the positioning shaft. The square edge at the bottom of the positioning shaft and the bottom of the outer diameter of the hexagonal socket at the top of the positioning shaft are provided with a transition edge.

[0026] The aforementioned spring sheet is a symmetrically stamped and bent metal elastomer, shaped like a "Y". One end of the fixed head of the spring sheet has a V-shaped opening with rear rolled edges on both sides, and the other end of the symmetrical elastic head of the spring sheet has a protruding curled head. The curled heads of the spring sheets on both sides of the bottom of the inner cover are respectively snapped into the end groove 701 of the bottom of the inner cover. Simultaneously, the rear rolled edges of the spring sheets abut against the inner wall of the arc-shaped rib 702 at the bottom reinforcing rib of the inner cover.
