Referring to fig. 1 to 7, a rotary dual-dose packaging bottle according to an embodiment of the present utility model may include an outer cylinder 100, an inner cylinder 200, and a drum 300. The inner cylinder 200 is disposed in the outer cylinder 100, and a first chamber 410 for accommodating a first medium is disposed inside the inner cylinder 200, and the inner cylinder 200 and the outer cylinder 100 together form a second chamber 420 for accommodating a second medium. At this time, the drum 300 is rotatably provided at the top of the outer tub 100, and one of the spiral groove 311 and the slider 221 is provided at the inner sidewall of the drum 300, and then the other of the spiral groove 311 and the slider 221 is provided at the outer sidewall of the inner tub 200. When the rotary drum 300 is rotated, the sliding block 221 drives the inner cylinder 200 to lift under the driving of the spiral groove 311, so as to realize the conduction and isolation of the first chamber 410 and the second chamber 420. If the first medium and the second medium are stored in the first chamber 410 and the second chamber 420 separately in the isolated state, they do not affect each other. If in the on state, the first medium and the second medium form a mixed medium.

In this embodiment, the first chamber 410 and the second chamber 420 can be mutually connected and isolated, and when the first chamber 410 and the second chamber 420 are in an isolated state, the first medium and the second medium can be respectively stored in the first chamber 410 and the second chamber 420 without mutual influence, which is beneficial to the long-time stable state of the first medium and the second medium without property change, thereby prolonging the shelf life and the shelf life of the first medium and the second medium. When the first chamber 410 and the second chamber 420 are in the conducting state, the first medium and the second medium are mixed to form a mixed medium for the user to take. In addition, in the embodiment, the user can realize the rapid mixing of the first medium and the second medium only by rotating the rotary drum 300, so that the operation is convenient, the structure is simple, the production cost is low, and the comfort level of the user in use is improved. Meanwhile, the device is also beneficial to carry and transport for users, can be used at any time, has strong practicability, and has great popularization and application value and market competitiveness.

Referring to fig. 1 and 5, in actual production, the drum 300 may be of a unitary or split type construction. If the bowl 300 is of a split construction, it may specifically include a third split 310 and a fourth split 320. At this time, the first ring groove 312 is disposed at an end of the third split body 310 away from the fourth split body 320, and cooperates with the first annular boss 113 on the outer cylinder 100 to rotatably fix the third split body 310 to the outer cylinder 100. In addition, a spiral groove 311 for abutting the slider 221 is also provided to the third split 310. In contrast, the second annular boss 321 is disposed at an end of the fourth split 320 away from the third split 310, and cooperates with the second annular groove 213 on the inner cylinder 200 to rotatably fix the fourth split 320 to the inner cylinder 200. In addition, external threads 322 for interfacing with the cover are also provided on the fourth sub-body 320.

Specifically, the fourth split body 320 is disposed toward one end of the third split body 310 through a gap between the third split body 310 and the outer cylinder 100, and is engaged with the outer cylinder 100 through an engaging structure. At this time, the user drives the inner cylinder 200 to ascend and descend by rotating the third split body 310 of the drum 300 to achieve the conduction and isolation of the first chamber 410 and the second chamber 420.

Referring to fig. 6 and 7, in order to further improve the connection strength and stability of the overall structure, a clamping block 323 capable of being clamped in the through hole 112 is disposed at the position of the fourth split body 320 corresponding to the through hole 112 of the outer cylinder 100.

In the foregoing embodiments, the descriptions of the embodiments are focused on, and the parts of a certain embodiment that are not described or depicted in detail may be referred to in the related descriptions of other embodiments.

It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
