Description

Technical Field

[0001] The utility model relates to the technical field of packaging bottles, in particular to a double-tube packaging container bottle. Background Art

[0002] With the development of modern industry and the consumer market, packaging container bottles, as an important component of commodities, have gradually evolved from single-functionality to multifunctionality, diversification, and high added value. In particular, in the fields of cosmetics, pharmaceuticals, and detergents, double-tube packaging container bottles, with their unique structural design and multi-cavity separation function, have become a new favorite in the market.

[0003] Reference patent application number 202321759785.1 discloses a double-tube packaging bottle with a tube-in-tube design, comprising: a hose bottle body and a bottle cap, wherein the bottle cap is threadedly mounted on the hose bottle body; wherein the hose bottle body is square and flat, the top of the hose bottle body is provided with a bottle mouth, and the outer wall of the bottle mouth is provided with an external thread; the hose bottle body is divided into an outer tube and an inner tube, the inner tube is located inside the outer tube, and a accommodating cavity is formed between the outer tube and the inner tube, which is used for packaging one raw material, and the inner tube is used for packaging another raw material; the bottle cap is threadedly connected to the outer wall of the bottle mouth.

[0004] However, in the above structure, an outer extrusion hole and an inner extrusion hole are respectively provided at the bottle mouth, and the outer extrusion hole and the inner extrusion hole are respectively connected to the outer tube and the inner tube. When the bottle body is squeezed, the substances in the inner tube and the outer tube will be squeezed out together. Although the discharge amount of the inner and outer tubes can be controlled by controlling the squeezing position, it is impossible to squeeze out the substances in the inner tube or the outer tube separately. Therefore, the packaging bottle can only accommodate two substances that can be mixed and used, and has poor practicality and low flexibility. Utility Model Content

[0025] like Figures 1 to 4 As shown, this embodiment discloses a double-tube packaging container bottle, including an outer bottle body 1, an inner bottle body 2 and a rotating cover 3. The bottle mouth of the inner bottle body 2 is provided with a first assembly head 21, the bottle mouth of the outer bottle body 1 is provided with a second assembly head 11, the inner side of the second assembly head 11 is provided with a first clamping cavity 12, the first assembly head 21 is clamped into the first clamping cavity 12 from the inside of the outer bottle body 1, and the rotating cover 3 is rotatably mounted on the second assembly head 11, a first liquid outlet 210 connected to the inside of the inner bottle body 2 is provided at the top edge of the first assembly head 21, and two liquid separation ports 110 connected to the first clamping cavity 12 are provided on the second assembly head 11. One of the liquid separation ports 110 is connected to the inner bottle body 2 through the first liquid outlet 210, and the other liquid separation port 110 is connected to the outer bottle body 1 through the first clamping cavity 12. A second liquid outlet 30 is provided on the rotating cover 3. Rotating the rotating cover 3 can make the second liquid outlet 30 connect to one of the liquid separation ports 110, so that the substances in the inner bottle body 2 and the outer bottle body 1 can be respectively discharged, thereby improving flexibility and practicality. Preferably, the rotation range of the rotating cover 3 is 0° to 180°. When the rotating cover 3 is just at 0° or 180°, the second liquid outlet 30 just connects to one of the liquid separation ports 110 or the other liquid separation port 110.

[0026] In this embodiment, in order to enable the first assembly head 21 to be clamped in the first clamping cavity 12, a clamping groove 121 is annularly provided along the cavity wall on the inner side of the first clamping cavity 12, and a first convex ring 211 is annularly provided on the first assembly head 21 along the outer wall of the first assembly head 21. The contour of the clamping groove 121 corresponds to the contour of the first convex ring 211. Specifically, in order to facilitate the clamping of the first convex ring 211 into the clamping groove 121, a first guide surface 122 is annularly provided along the edge of the cavity wall at the bottom of the first clamping cavity 12, and a second guide surface 212 that cooperates with the first guide surface 122 is provided on the upper side of the first convex ring 211. The first guide surface 122 and the second guide surface 212 are conical surfaces.

It should be noted here that there is a gap between the top surface of the first assembly head 21 and the top surface of the first clamping cavity 12, so as to be used to discharge the material in the outer bottle body 1 from one of the liquid separation ports 110. Therefore, it can be determined that the first liquid outlet 210 extends upward from the top plane of the first assembly head 21 and is connected to the other liquid separation port 110. In order to improve the sealing performance, an extension port 111 is extended downward from the bottom of the liquid separation port 110 connected to the first liquid outlet 210, and the extension port 111 is inserted into the first liquid outlet 210 to form a seal; preferably, in order to increase the discharge speed of the material in the outer bottle body 1, the liquid guide groove 213 is provided with two groups, and the two groups of liquid guide grooves 213 are symmetrically arranged on both sides of the first assembly head 21.

[0029] Furthermore, an annular edging 32 extends downward from the top surface of the second engaging cavity 31, and the annular edging 32 is sleeved on the top of the second assembly head 11. Specifically, the annular edging 32 and the side wall of the second assembly head 11 are sealed by a sealing ring. When the annular edging 32 is sleeved on the second assembly head 11, the top surface of the second assembly head 11 is against the top surface of the second engaging cavity 31, and the two liquid separation ports 110 are separated by a sealing ring arranged on the top surface of the second engaging cavity 31.

[0030] In this embodiment, the rotating cover 3 is further provided with a flip cover 4 for covering the second liquid outlet 30. One end of the flip cover 4 is detachably inserted into one side of the rotating cover 3. Specifically, a slot 33 is provided on the rear side of the rotating cover 3. An insertion rod 41 is movably connected to the rear side of the flip cover 4. A buckle 42 is provided at the end of the insertion rod 41. After the insertion rod 41 is inserted into the slot 33, it is fixed at the bottom of the slot 33 by the buckle 42. After the flip cover 4 is closed, the second liquid outlet 30 is sealed. By providing a detachable flip cover 4, the flip cover 4 of different colors and styles can be replaced, thereby improving recognition and aesthetics.
