Description

Technical Field

[0001] This invention relates to the field of cosmetic packaging, and in particular to a semi-circular rotating cosmetic bottle. Background Technology

[0002] Packaging tubes are widely used in cosmetics due to their lightweight nature and ease of use and portability. Because the tubes are flexible and dispense cosmetic liquid by squeezing, the reliability of the seal is crucial. Poor sealing can lead to spillage during transport or handling, causing contamination and waste. Currently, most tube packaging bottles are heat-sealed before use, making resealing difficult after opening, which is inconvenient for travel. Furthermore, while some cosmetic bottles come with brushes, these brushes are merely aids; the contents must be moistened before application to the skin. Summary of the Invention

[0003] In order to overcome at least one of the problems mentioned above, the present invention provides a semi-circular rotating cosmetic bottle that can be sealed and is easy to use.

[0004] The technical solution adopted by this invention to solve its technical problem is: a semi-circular rotating cosmetic bottle, comprising:

[0005] The bottle body is used to store the contents of cosmetics, and the bottle body has an opening at the top;

[0006] The base is fitted onto the bottle mouth from the bottom. The upper periphery of the base is an outer connecting sleeve. The middle part of the outer connecting sleeve is a first concave cavity. A plunger is provided in the middle of the first concave cavity, and at least one through hole is provided on the side.

[0007] The limiting sleeve is screwed onto the outer connecting sleeve. The lower part of the limiting sleeve is a second concave cavity, and a narrow opening is provided in the middle of the second concave cavity. The narrow opening protrudes upward and corresponds to the plunger. After the limiting sleeve rotates down, the plunger closes the narrow opening. After the limiting sleeve rotates up, the narrow opening separates from the plunger, opens, and communicates with the contents of the bottle. Adjusting the distance of the limiting sleeve's rotation up / down controls the amount of liquid dispensed.

[0008] A sealing ring is provided on the lower side of the narrow opening, and the sealing ring is attached to the inner wall of the first concave cavity.

[0009] Preferably, a one-way rotation limiting structure is provided between the limiting sleeve and the base, including a first guide block disposed below the base and a second guide block disposed at the bottom of the limiting sleeve; when tightened, the contact surface on one side of the first guide block and the second guide block is an inclined guide surface, which can rotate; when loosened, the contact surface on one side of the first guide block and the second guide block is a longitudinal limiting surface, and the longitudinal limiting surfaces of the first guide block and the second guide block cannot rotate when they are in contact, so that the limiting sleeve and the base cannot be rotated apart after installation.

[0010] Preferably, a rotation adjustment structure is provided between the limiting sleeve and the base, including a first adjusting column disposed below the base and a second adjusting column disposed inside the limiting sleeve. An adjustment area is formed between the first adjusting column and the first guide block, and the second adjusting column is located within the adjustment area and rotates within the adjustment area.

[0011] Preferably, the outer surfaces of the first and second adjusting columns are arc-shaped, allowing the first and second adjusting columns to pass through each other when rotated under force.

[0012] Preferably, the first guide block and the second guide block are a pair and are arranged symmetrically.

[0013] Preferably, the upper part of the limiting sleeve is provided with a third cavity, the narrow opening is located at the bottom of the third cavity, and a cotton brush is provided in the third cavity. The cosmetic liquid enters the cotton brush through the narrow opening and is applied to the skin through the cotton brush.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] Example

[0027] like Figure 1 , 2 The semi-circular rotating cosmetic bottle shown in Figure 3 consists of a bottle body 1, a base 2, a limiting sleeve 4, and an outer cap 8. The limiting sleeve 4 can rotate within a certain range, and the bottle body 1 can be closed by rotating. The flow rate of liquid from the bottle body 1 can also be adjusted by rotating. It is convenient to use, can be opened or sealed at any time, is easy to carry for travel, and prevents accidental squeezing and leakage.

[0028] See Figure 3 The bottle body 1 is used to store the contents of the cosmetic. The upper part of the bottle body 1 has a bottle mouth 11, through which the contents of the cosmetic liquid are squeezed out.

[0029] The base 2 is fitted onto the bottle mouth 11 from the bottom. The upper periphery of the base 2 is an outer connecting sleeve 3. The middle part of the outer connecting sleeve 3 is a first concave cavity 31. A plunger 32 is provided in the middle of the first concave cavity 31. At least one through hole 33 is provided on the side. The through hole 33 is connected to the bottle body 1. The contents of the cosmetic liquid flow out through the through hole 33.

[0030] See Figure 4 The limiting sleeve 4 is screwed onto the outer connecting sleeve 3. The lower part of the limiting sleeve 4 is a second concave cavity 41. A narrow opening 42 is provided in the middle of the second concave cavity 41. The narrow opening 42 is a conical structure and protrudes upward. The narrow opening 42 corresponds to the plunger 32. After the limiting sleeve 4 rotates down, the plunger 32 closes the narrow opening 42. After the limiting sleeve 4 rotates up, the narrow opening 42 separates from the plunger 32 and opens, communicating with the contents of the bottle 1. The amount of liquid output is controlled by adjusting the distance of the limiting sleeve 4 rotating up / down.

[0031] In this embodiment, a sealing ring 43 is provided on the lower side of the narrow opening 42. The sealing ring 43 is attached to the inner wall of the first concave cavity 31 to ensure that its rotation position does not come into contact with the cosmetic liquid.

[0032] See Figure 5 ,6 In this embodiment, a one-way rotation limiting structure is provided between the limiting sleeve 4 and the base 2, including a first guide block 51 disposed below the base 2 and a second guide block 52 disposed at the bottom of the limiting sleeve 4; when tightened, the contact surface on one side of the first guide block 51 and the second guide block 52 is an inclined guide surface 53, which can rotate; when loosened, the contact surface on one side of the first guide block 51 and the second guide block 52 is a longitudinal limiting surface 54. When the longitudinal limiting surfaces 54 of the first guide block 51 and the second guide block 52 are in contact, they cannot rotate. After the limiting sleeve 4 and the base 2 are installed, they cannot be rotated apart.

[0033] See Figure 5 , 6 A rotation adjustment structure is provided between the limiting sleeve 4 and the base 2, including a first adjustment column 61 located below the base 2 and a second adjustment column 62 located inside the limiting sleeve 4. An adjustment area is formed between the first adjustment column 61 and the first guide block 51, and the second adjustment column 62 is located within the adjustment area and rotates within the adjustment area.

[0034] See Figure 6 The outer surfaces of the first adjusting column 61 and the second adjusting column 62 are arc-shaped, allowing them to pass through each other when rotated under force. Therefore, the rotary adjusting structure only serves as an adjustment indicator. When the second adjusting column 62 enters the adjustment area, it emits a clicking sound as it passes the first adjusting column 61. In the design, when the second adjusting column 62 is within the adjustment area, the plunger 32 and the narrow opening 42 are in a range from tightly closed to fully open.

[0035] In this embodiment, the first guide block 51 and the second guide block 52 are a pair, symmetrically arranged. Their reverse rotation angle is limited to within 180 degrees.

[0036] In this embodiment, a third recess 44 is provided on the upper part of the limiting sleeve 4, and a narrow opening 42 is located at the bottom of the third recess 44. A cotton brush 7 is disposed inside the third recess 44. The cosmetic liquid enters the cotton brush 7 through the narrow opening 42 and is applied to the skin through the cotton brush 7. The cotton brush 7 is made of soft cotton, which allows the cosmetic liquid to be applied to the skin while preventing the cosmetic liquid from splashing. The outer cover 8 covers the cotton brush 7 and the limiting sleeve 4 and is fitted onto the outer edge of the bottom of the base 2.

[0037] In this embodiment, there are two through holes 33, which are respectively located on both sides of the plunger 32, and the structure is symmetrical.

[0038] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
