Patent Description:
At present, the quantitative subpackaging of cosmetic emulsions and solutions is basically realized in canning factories, which features fixed volume and large canning and subpackaging equipment, which is not suitable for subpackaging in stores. Specifically, the customization requirement of customers cannot be met, subpackaging experience of customers cannot be realized, and a switch of an existing product subpackaging system may be turned on accidentally, which will make perfume flow out to cause waste. In another word, the switch does not have the function of being turned on when used and locked when unused. An example of a subpackaging bottle is known from <CIT>.

Aiming at the above defects in the background art, the invention provides a self-locking subpackaging bottle with a simple structure and a self-locking switch.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: a self-locking subpackaging bottle comprises a bottle body, a bottle cap and an adapter;.

Further, the diameter of the outer wall of the receiving cap is greater than that of the rotating cap, which allows the rotating cap to easily extend downward into the inner wall of the rotating ring, and the receiving cap directly fits to the fixing ring above the rotating ring.

Further, the bottom of the inner wall of the annular cap is provided with an internal thread for connecting an empty bottle.

Further, the rotating ring comprises a handle, a first rotating sleeve, a connecting body and a second rotating sleeve, the first rotating sleeve and the second rotating sleeve are respectively connected to two sides of the connecting body, the handle is connected to the connecting body, the connecting body is connected to the first bearing through the second rotating sleeve, a notch is formed in the annular cap, the handle extends out of the adapter cap from the notch, and an initial end of the notch is L-shaped.

Further, an end, connected to the connecting body, of the handle is designed as an arc-shaped piece, the connecting body is connected to a limit screw, a round hole is formed in the arc-shaped piece, the diameter of the round hole is greater than that of the limit screw, and an elastic piece is arranged between the connecting body and the arc-shaped piece; two groups of elastic pieces are arranged at each end of the arc-shaped piece; and when the handle is located at the initial end of the notch, the outer elastic piece supports the arc-shaped piece upwards, and the inner elastic piece pulls the handle downwards and fits into a tail end of the L-shaped groove to limit the lateral position of the handle.

Further, a stopper is hinged to the outside of the adapter cap and comprises a connecting strip and a stopper strip, the middle of the connecting strip is hinged to the outside of the adapter cap, the stopper strip is arranged at one end of the connecting strip, and extends to the rotating ring through a stopper opening formed in the adapter cap, the connecting body of the rotating ring is provided with a recess matched with the stopper strip, and a reset spring is arranged between the stopper strip and the annular cap.

Further, the stopper strip is arranged in the diameter direction of the adapter cap, and the stopper strip is arranged at an end away from the adapter cap.

Further, a sealing gasket is arranged between the receiving cap and the rotating cap, the sealing gasket is provided with a through hole, the seal gasket is arranged at the bottom of the receiving cap, the through hole in the sealing gasket is aligned with the through hole in the receiving cap, and the through hole in the rotating cap is movable relative to the through hole in the receiving cap; the through hole comprises an air flow hole and a liquid flow hole; when the through hole in the rotating cap is misaligned with the through hole in the receiving cap, the bottle cap is closed; only when the rotating cap rotates and the inner through hole is aligned with the through hole in the receiving cap, can the bottle cap be in an open state; and the liquid flow hole is directly designed on the receiving cap, the air flow hole is connected to an air guide tube, and an air port at the other end of the air guide tube is at an air position of the inverted bottle body.

Further, the receiving cap is connected to the bottle body through an internal thread for fixing the bottle cap.

Operation steps: An empty bottle is connected to a screw thread at the bottom of the adapter cap; when the empty bottle rotates and rises, a bottle body of the empty bottle touches the hinged stopper, and the position of the connecting strip on the side of the bottle body rises and the position on the side of the stopper strip falls. Therefore, the stopper strip is separated from a recess of the rotating ring, the rotating ring is unlocked, the handle is lifted to the transverse direction of the notch, the rotating ring is moved through the handle so as to drive the adapter cap to rotate, the through hole in the adapter cap is aligned with the through hole in the receiving cap, the bottle cap is opened, and then the product in the bottle body can flow into the empty bottle below through the liquid flow hole to achieve subpackaging. After subpackaging, the handle is loosened to close the bottle cap, and the empty bottle is taken out; and under the action of the reset spring on the stopper, the stopper strip moves upward again to fit into the recess of the rotating ring, so as to realize self-locking of the handle.
