[0026] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0027] A sealed, rotatable ointment bottle, see attached document. Figures 1-10 It includes parts such as outer cover 1, top cover 2, bottle body 4, screw 5, screw sleeve 3, and bottom cover 6.

[0028] The inner wall of the outer cover 1 is provided with a threaded structure 12, and the inner top surface is provided with a protruding plug 11.

[0029] The upper outer end of the cover 2 is provided with a threaded structure 22; the upper inner side wall is provided with a groove 24; the top is provided with an annular rib 23 and a through hole 21. The interior forms a hollow circumferential cavity; the cavity is provided with a vertical rib 25 that can mate with the bottle body 4.

[0030] The outer cover 1 and the upper cover 2 are fitted together by a threaded structure. The protruding plug 11 inside the outer cover 1 is inserted into the through hole 21 at the top of the upper cover 2, and the interference fit forms a seal. In this embodiment, the through hole 21 is a round hole.

[0031] The upper part of the bottle body 4 is provided with a rib 41 for sealing and a ring 42 for fixing with the upper cover 2; a third annular rib 43 is also provided, and the annular rib 43 is provided with four triangular locking protrusions 44 that cooperate with the vertical ribs 25 of the inner cavity of the upper cover 2.

[0032] The upper part of the bottle body 4 forms a cavity C for containing the contents, and the side wall of cavity C has four raised guide ribs 48.

[0033] The lower outer end of the bottle body 4 is provided with a connecting rib 45 for engaging with the bottom cap 6. The lower outer end of the bottle body 4 is provided with two symmetrical elastic protrusions 46. When rotating, these two elastic protrusions 46 contact and deform with the contact rib 62 at the lower end of the inner wall of the bottom cap 6, producing a rotating feel and sound.

[0034] A ring 47 is provided at the lower end of the inside of the bottle body 4, such as Figure 1 The threaded cylindrical part inside the annular ring 47 is used to accommodate the threaded sleeve 3, which plays a role in positioning the threaded sleeve 3 and assists the threaded sleeve 3 in forming an interference fit with the lower end of the screw 5.

[0035] The protruding rib 41 of the bottle body 4 is press-fitted with the inner upper side wall of the top cover 2 to form a seal. The connecting rib 45 of the bottle body 4 is matched with the mating structure 61 of the bottom cover 6 for positioning. The mating structure 61 can be an annular mating rib, and the two are interlocked, or it can be an annular mating groove. The annular protruding rib 42 of the bottle body 4 is fixed with the annular groove 24 of the top cover 2. The triangular locking protrusion 44 on the annular protruding rib 43 of the bottle body 4 is matched with the vertical rib 25 in the inner cavity of the top cover 2 to achieve the anti-rotation function between the bottle body 4 and the top cover 2.

[0036] The screw sleeve 3 has a threaded structure 31 inside, which mates with the threaded structure 51 of the screw 5. The outer circular surface of the screw sleeve 3 has four concave arc surfaces 32, which are in interference contact with the four raised guide ribs 48 on the side wall of the receiving cavity of the bottle body 4, thus achieving a sealing effect.

[0037] The inner surface A of the threaded part of the sleeve 3 is press-fitted with the shoulder B of the lower end of the screw 5 to form a seal; the sleeve 3 is placed in the receiving cavity C of the bottle body 4 and press-fitted with the inner wall of the bottle body 4 to form a seal. With the above structure, when the contents, such as lipstick, are injected into the receiving cavity of the bottle body 4, the assembled parts form a sealed receiving cavity.

[0038] The upper part of the screw 5 is provided with a threaded structure 51, which mates with the threaded structure 31 of the screw sleeve 3. The lower end of the screw 5 is provided with a disc 52, which has four positioning notches 53. These four positioning notches 53 are positioned and engaged with the four positioning protrusions 63 of the bottom cover 6. The screw 5 is fixedly positioned by the positioning notches 53 and the positioning protrusions 63 of the bottom cover 6; the screw sleeve 3 and the screw 5 are engaged by threads.

[0039] The upper end of the inner wall of the bottom cover 6 is provided with a mating structure 61, which mates with the connecting rib 45 at the lower end of the outer side of the bottle body 4 to install the bottom cover 6 on the bottle body 4; the lower end of the inner wall of the bottom cover 6 is provided with a number of contact ribs 62, which are circumferentially distributed on the inner wall of the bottom cover 6 and are used to contact the elastic protrusion 46 at the lower end of the outer side of the bottle body 4 to produce a rotating feel and sound.

[0040] The bottom cover 6 has a central protrusion. During assembly, the central protrusion is inserted into the central hole of the screw 5 to position the screw 5.

[0041] Working principle:

[0042] like Figure 9 As shown, this state indicates that the lipstick bottle has just been filled with its contents and is not yet used. The entire product forms four sealing points: seal 1, formed by the interference fit between the plug 11 and the through hole 21; seal 2, formed by the interference fit between the rib 41 of the bottle body 4 and the inner upper side wall of the cap 2; seal 3, formed by the interference fit between the screw sleeve 3 and the inner side wall of the bottle body 4; and seal 4, formed by the interference fit between the inner side A of the threaded part of the screw sleeve 3 and the shoulder B of the lower end of the screw 5.

[0043] like Figure 10 As shown, remove the outer cap, hold the middle of the top cap, and rotate the bottom cap 6 in the direction of the arrow shown in the figure. The bottom cap 6 drives the screw 5 to rotate together. The screw 5 drives the screw sleeve 3 to move upward along the four guide ribs 48 on the inner wall of the bottle body 4 through the thread structure, thereby driving the contents to be discharged through the through hole 21 at the top of the top cap 2, so as to achieve the purpose of use.

[0044] like Figure 10 As shown, during the rotation, the two symmetrical elastic protrusions 46 at the lower outer end of the bottle body 4 come into contact with the contact ribs 62 at the lower inner end of the bottom cover 6, and then disengage, generating a rotating feel and sound in a cycle, providing the user with a good experience and comfort.

[0045] The multi-layered sealing structure used in this solution can prevent the contents from being contaminated by the outside world as much as possible; all parts are made of the same plastic material, which is easy to recycle and more environmentally friendly and energy-saving; it also helps to reduce product costs; and improves the user experience and comfort.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
