This cosmetic container includes a lid body, a discharge tray, a leak-proof valve, an inner lid, a middle ring, a piston, a screw rod, and a bottle body that are coaxially arranged. The screw rod is provided with a discharge channel, the discharge tray is provided with a discharge port, the inner lid is fixed inside the discharge tray, the middle ring is fixedly sleeved on the bottle mouth of the bottle body, the lid body is detachably sleeved on the middle ring, the bottle body is provided with a containing space for filling cosmetic materials, the discharge tray is inserted into the middle ring and the discharge tray can rotate circumferentially relative to the middle ring, the screw rod includes a rod member and a head, the head is fixedly inserted into the discharge tray, the piston is sleeved and screwed on the rod member, the piston is airtightly attached to the inner wall of the bottle body, the leak-proof valve is sleeved on the head and sealed at the upper end of the discharge channel, the lower end of the discharge channel communicates with the containing space of the bottle body, when the discharge tray rotates, the screw rod rotates synchronously, and the piston moves downward along the screw rod under the action of the screw rod to squeeze the cosmetic material into the discharge channel, and the cosmetic material pushes open the leak-proof valve and discharges through the discharge port.

[0004] This cosmetic container can discharge materials by rotating the discharge tray. However, the discharge tray of this cosmetic container can rotate in both directions, so that the piston can both rise and fall, and when rotating in both forward and reverse directions, the feedback force received by the user is almost the same, and it is difficult for the user to judge whether the rotation direction can discharge materials. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the utility model provides a spiral extrusion cream jar. This spiral extrusion cream jar can only discharge materials when rotating in one direction, and can emit a prompt sound when rotating in the reverse direction to prompt that the rotation direction is opposite, so that the user can judge the correct rotation direction for discharging materials.

[0006] To solve the above technical problems, the utility model is solved by the following technical solutions: A spiral extrusion cream jar, including a jar body, a rotating cover is rotatably arranged on the jar body, a discharge port is arranged on the rotating cover, a screw rod with a discharge channel inside is arranged at the bottom of the discharge port, the discharge channel communicates with the discharge port, a piston threadedly connected to the screw rod is arranged inside the jar body, a rotating sleeve is arranged between the jar body and the rotating cover, the screw rod passes through the rotating sleeve, a plurality of limiting grooves are annularly arranged on the inner wall of the rotating cover, elastic pieces are arranged on the outer periphery of the rotating sleeve, limiting blocks are arranged on the elastic pieces, one side of the limiting block is a slope, a guiding groove is arranged on the rotating sleeve close to the side of the screw rod, a guiding strip that can lift in the guiding groove is arranged on the piston. When the rotating cover rotates towards one side, the rotating cover drives the rotating sleeve to rotate, and the piston moves downward; when the rotating cover rotates towards the other side, the elastic piece is guided by the slope to rotate inwards, and the limiting block sequentially passes through the limiting grooves in the rotating cover to emit a prompting sound. When this spiral extrusion cream jar rotates the rotating cover in the correct discharging direction, the rotating cover drives the rotating sleeve to rotate, drives the piston to rotate, and when the piston rotates, it cooperates with the screw rod, and the piston moves downward, and the cream inside can be extruded from the discharge port through the discharge channel; when the rotating cover rotates towards the other direction, due to the slope guiding the elastic piece to rotate inwards, the limiting block will sequentially pass through the limiting grooves in the rotating cover to emit a "click, click, click" prompting sound, and at this time the rotating sleeve will not rotate and the piston will not move, so that the user can judge the correct rotating direction of discharging.

[0007] In the above technical solution, preferably, a limiting sleeve is arranged at the bottom of the discharge port inside the rotating cover, the screw rod is inserted into the limiting sleeve, a non-circular limiting portion is arranged on the screw rod, the limiting sleeve non-rotatably limits the non-circular limiting portion, the bottom of the screw rod abuts against the bottom surface of the jar body, and an opening communicating with the discharge channel is arranged laterally at the bottom end of the screw rod. Adopting this structure to limit the rotation of the screw rod has a simple structure and does not require an additional positioning structure, and is also convenient for assembly.

[0008] In the above technical solution, preferably, a bending buffer portion is arranged at the top of the screw rod, a plug is arranged at the top of the bending buffer portion, and the plug abuts against the discharge port. Adopting this structure can provide a certain extrusion force to the plug through the bending buffer portion to avoid accidental leakage of the cream inside.

[0009] In the above technical solution, preferably, a guiding sleeve is arranged on the piston, the guiding sleeve is located outside the limiting sleeve, and a sealing ring is arranged between the guiding sleeve and the limiting sleeve. Adopting this structure can avoid the cream leaking from the center of the piston into the rotating cover.

[0010] In the above technical solution, preferably, the guiding strip is located on the outer wall of the guiding sleeve.

[0011] Compared with the prior art, the present utility model has the following beneficial effects: When the rotary cap rotates in the correct discharging direction, the rotary cap drives the rotary sleeve to rotate, drives the piston to rotate, and when the piston rotates, it cooperates with the screw rod, the piston moves downward, and the cream inside can be extruded from the discharge port through the discharge channel; When the rotary cap rotates in the other direction, due to the inclined surface guiding the elastic sheet to rotate inward, the limiting block will successively pass through the limiting groove in the rotary cap and emit a "click click" prompt sound, and at this time the rotary sleeve will not rotate and the piston will not move, so that the user can judge the correct rotation direction of discharging.
