Description

Paste container Technical Field

[0001] The present invention relates to a container, in particular to a paste container. Background Art

[0002] Currently, existing cosmetic containers usually rotate the base to rotate the screw, which drives the nut to move up and down to achieve material discharge. However, when the amount of cosmetics remaining is small during use, the user needs to rotate the base multiple times to achieve material discharge, which is inconvenient to use. Alternatively, the user cannot effectively control the rotation angle when rotating the base, making it difficult to accurately adjust the length of the cream extended, resulting in waste of cream.

[0032] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0033] This specific embodiment records in detail the paste container of the present application, as shown in Figures 1 to 15, the paste container includes: a lid 1, an inner bottle 2, a stopper 3, a screw 4, a base 5 and an inner lid 6 fixed to the top of the inner bottle 2, the bottom of the lid 1 and the base 5 are detachably connected, the stopper 3 is arranged in the inner bottle 2 and is circumferentially fixed to the inner bottle 2, the bottom of the screw 4 and the base 5 are circumferentially fixed, the top of the screw 4 extends into the first through hole at the bottom of the inner bottle 2 and is threadedly connected to the stopper 3, the base 5 is sleeved on the bottom of the inner bottle 2 and is rotatably connected to the inner bottle 2, the base 5 can rotate in a stepwise unidirectional manner relative to the inner bottle 2, the top of the stopper 3 can carry the paste 7, the screw 4 rotates with the rotation of the base 5 and drives the stopper 3 to move toward the top of the inner bottle 2, and then squeezes the paste 7 out of the discharge hole 61 at the top of the inner lid 6. During use, the user rotates the base 5. Since the base 5 can only rotate in one direction relative to the inner bottle 2, the user only needs to rotate the base 5 a certain number of steps as needed to control the amount of the paste 7 discharged. This is not only easy to operate, but also allows the user to control the amount of the paste 7 discharged as needed. This has the advantages of being easy to use and being able to accurately control the amount of the paste 7 discharged.

[0034] Referring to Figures 6 and 9 , in this embodiment, optionally, a circle of ratchet teeth 51 is provided on the inner wall of the base 5, and a spring clip 23 is provided on the bottom of the inner bottle 2. Specifically, the spring clip 23 is provided on the side wall of the bottom of the inner bottle 2. By rotating the base 5, the ends of the spring clip 23 can sequentially engage in the spaces between the ratchet teeth 51 in a unidirectional manner. This sequential engagement of the ends of the spring clip 23 in the spaces between the ratchet teeth 51 enables stepwise, unidirectional rotation of the base 5 relative to the inner bottle 2.

[0035] Please refer to FIG. 6 . Optionally, in this embodiment, the ratchet teeth 51 are evenly spaced and distributed on the inner wall of the base 5 to ensure that the angle of each step rotation is the same.

[0036] Referring to Figures 3, 9, and 10, in this embodiment, a plurality of first anti-rotation bars 21 are optionally provided in the middle of the outer wall of the inner bottle 2, and a circle of first protrusions 62 are provided on the inner wall of the inner lid 6, which can cooperate with the first anti-rotation bars 21. The first protrusions 62 are inserted into the gaps between the two first anti-rotation bars 21 to achieve circumferential fixation of the inner lid 6 and the inner bottle 2.

[0037] Referring to Figures 11 and 12 , in this embodiment, the screw 4 optionally includes a rod 41 that radially extends to form a base 42 with two steps. The rod 41 engages with the plug 3, and when the base 5 is rotated, the rod 41 drives the plug 3 upward. The base 42 is located within the base 5. The sidewalls of the base 42 are circumferentially provided with at least two second anti-rotation bars 43. The inner wall of the bottom of the base 5 radially protrudes inward to form at least one second protrusion 52. The second protrusion 52 is located between two adjacent second anti-rotation bars 43, thereby achieving circumferential fixation between the screw 4 and the base 5. In this embodiment, the number of second protrusions 52 is four, and they are evenly spaced along the inner wall of the bottom of the base 5. In some alternative embodiments, the number of second protrusions 52 may also be other numbers, such as three, five, or six. In this embodiment, the end of the second anti-rotation bar 43 near the bottom of the base 42 is chamfered to facilitate the second protrusion 52 to fit into the gap between two adjacent second anti-rotation bars 43, facilitating assembly.

[0038] Optionally in this embodiment, the side wall of the base 42 is further provided with a circle of fixing hooks 44, and the inner wall of the base 5 is provided with a fixing groove 53 that can cooperate with the fixing hooks 44, so as to improve the firmness of the fixation between the base 42 and the base 5 and prevent the base 42 from accidentally detaching from the base 5 during use.

[0039] Please refer to Figures 9, 11 and 14. In this embodiment, optionally, the outer wall of the stopper 3 is in close contact with the inner wall of the inner bottle 2, and the inner wall of the inner bottle 2 is provided with multiple third anti-rotation strips 24. The outer wall of the stopper 3 is provided with a groove 34 that can cooperate with the third anti-rotation strip 24. The circumferential fixation of the stopper 3 and the inner bottle 2 is achieved by snapping the third anti-rotation strip 24 into the groove 34.

[0040] Referring to Figures 14 to 16 , in this embodiment, the plug 3 optionally includes a nut 31, an inner ring 32, and a carrier 33. The nut 31 and the carrier 33 are respectively engaged with the two sides of the inner ring 32. A threaded hole is provided in the middle of the nut 31. A fixing seat 36 is provided protruding from the middle of the inner ring 32. A second through hole is provided in the middle of the fixing seat 36 for the passage of the screw 4. A third through hole is provided in the middle of the carrier 33 for the passage of the fixing seat 36. The paste 7 is provided on the top of the carrier 33, and the screw 4 passes through the paste 7. The screw 4 can be threadedly connected to the threaded hole, and the screw 4 can pass through the second through hole and then pass through the paste 7.

[0041] In this embodiment, the screw 4 is optionally provided with two opposing flat surfaces 45, each of which has third protrusions 46 extending axially along the screw 4. A clearance groove 35 is defined on either side of the second through hole, allowing the two third protrusions 46 to pass through. The nut 31, inner ring 32, and carrier 33 are relatively stationary. The interaction between the clearance groove 35 and the third protrusion 46 improves the stability of the stopper 3 during movement and prevents the stopper 3 from tilting during movement.

[0042] Optionally, in this embodiment, the outer wall of the inner bottle 2 is provided with a circle of positioning protrusions 22 , and the inner wall of the base 5 is provided with a circle of positioning grooves that can rotate with the positioning protrusions 22 .

[0043] The paste container of this embodiment has the advantages of being easy to use and being able to accurately control the extended length of the paste.
