Claims

1. A cosmetic product packaging hose having a discharge control function, characterized by, include: A flexible tube used to store contents; the upper part of the tube has an opening that allows the contents to be squeezed out. The base includes an outer ring and an inner tube. The outer ring is fitted around the outer edge of the hose opening, and the inner tube extends into the hose opening. A first side hole is provided on one side of the inner tube to allow the contents of the hose to be discharged. The inner plug has a flow-limiting tube at the bottom, which is inserted into the inner tube and adapted to it. A second side hole is provided on one side of the flow-limiting tube. The flow-limiting tube can be rotated to make the second side hole connect with or be offset from the first side hole. When the second side hole connects with the first side hole, the contents of the tube are squeezed out and discharged through the flow-limiting tube to the upper outlet of the inner plug to complete the use of the cosmetic contents. A pressure cap is fitted onto the outer edge of the inner plug and the base, limiting the inner plug to the base and rotatably engaging with the base; a first rotation limiting structure is provided between the pressure cap and the inner plug, the first rotation limiting structure includes at least one first limiting protrusion provided on the outer edge of the inner plug and a first limiting groove provided in the pressure cap, the first limiting protrusion engages in the first limiting groove, so that the pressure cap and the inner plug can rotate together, and the opening and closing of the contents of the hose can be achieved by controlling the rotation of the pressure cap; It also includes an upper cover, and a second rotation limiting structure is provided between the upper cover and the pressure cap. The second rotation limiting structure includes a second limiting protrusion provided on the inner edge of the upper cover and a second limiting groove provided on the outer edge of the pressure cap. After the upper cover is put on, the second limiting protrusion is inserted into the second limiting groove on the outer edge of the pressure cap, and the upper cover and the pressure cap rotate together. The opening and closing of the contents of the hose can be achieved by controlling the rotation of the upper cover. A rotation locking structure is provided between the upper cover and the base, including a locking protrusion inside the upper cover and a guide locking groove on the outer edge of the outer ring of the base; the guide locking groove includes a longitudinal groove, an oblique guide groove, and a locking groove; after the upper cover is put on, the locking protrusion enters the longitudinal groove, rotates along the oblique guide groove, and enters the locking groove, locking the upper cover and the base together. At the same time, the second limiting protrusion is engaged in the second limiting groove on the outer edge of the pressure cap, causing the inner plug to rotate, so that when the upper cover is engaged with the base, the second side hole is misaligned with the first side hole, closing the contents of the hose; when the outer cover is rotated to the open position of the longitudinal groove, the second side hole communicates with the first side hole, opening the contents of the hose.

2. The cosmetic packaging soft tube with a discharge control function according to claim 1, characterized in that: The locking protrusion and the second limiting protrusion are located on the same longitudinal line, and the longitudinal groove and the second limiting groove are located on the same longitudinal line. After the locking protrusion is guided into the longitudinal groove by the second limiting groove, the second limiting protrusion is simultaneously engaged in the second limiting groove.

3. The cosmetic packaging soft tube with a discharge control function according to claim 2, characterized in that: The upper part of the base is provided with a rotation limiting groove, and the inner plug is provided with a corresponding rotation guide limiting block. After the inner plug is fitted into the base, the rotation guide limiting block is located in the rotation limiting groove so that the inner plug can be quickly positioned.

4. The cosmetic packaging soft tube having a discharge control function according to claim 3, characterized in that: It also includes a massage head, which is attached to the upper part of the inner cover and fixed by a pressure cover; the pressure cover has a limiting and narrowing structure extending from the upper part to the middle, which is attached to the massage head to fix it.

5. The cosmetic packaging soft tube having a discharge control function according to claim 4, characterized in that: The massage head is made of silicone, with a liquid outlet in the middle that connects to the inner plug, and a ring-shaped arc surface structure around the perimeter.

6. The cosmetic packaging soft tube with a discharge control function according to claim 5, characterized in that: The massage head is composed of zero-degree silicone, TPU film, and TPU soft plate.
