[0018] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain this application and are not configured to limit this application. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0019] Reference Figure 1-4 This application provides an embodiment of a container with a replaceable inner bottle, comprising an outer bottle 1, a rotating ring 2, a screw cap 3, an inner bottle 4, and a cap 5. The inner bottle 4 is disposed within the rotating ring 2, which is disposed within the outer bottle 1. The outer bottle 1 includes a connecting limiting component, the rotating ring 2 includes a rotating sliding component, and the screw cap 3 includes a rotating limiting component, a base, and a cap plate. When the screw cap 3 is rotated, the connecting limiting component, the rotating sliding component, and the rotating limiting component are linked together to lock or replace the inner bottle and to press and lock the cap. This container allows for locking or replacing the inner bottle and also allows for pressing and locking the cap to prevent accidental pressing and waste of fluid. Furthermore, it allows for replacement of the inner bottle to reduce manufacturing costs.

[0020] In one embodiment, the bottom of the inner bottle 4 is provided with an inner bottle locking rib 8, and the upper part of the inner bottle 4 is provided with a large ring 6 and a cap 5 in sequence. The large ring 6 is threadedly connected to the inner bottle 4, and the cap 5 is pressed up and down on the outer surface of the large ring 6. The cap is provided with a liquid outlet end. The connecting limiting component includes an outer bottle protrusion 101 or an outer bottle guide groove. The outer bottle protrusion 101 or the outer bottle guide groove is located at the lower part of the inner wall of the outer bottle 1. The outer bottle guide groove is spirally arranged along the inner wall of the outer bottle 1. The rotating sliding component includes a rotating ring guide groove 201 or a rotating ring protrusion. The protrusion and the guide groove are connected in cooperation. The rotating sliding component further includes a rotating ring positioning rib 202 and a rotating ring limiting surface 203. The rotating ring limiting surface 203 abuts against and limits the bottom surface 7 of the cap above the inner bottle. The rotating limiting component includes a cap positioning rib 304. The rotating ring positioning rib 202 and the cap positioning rib 304 are connected in a cooperating manner. By the concave-convex positioning of the rotating ring positioning rib 202 and the cap positioning rib 304, the movable cooperation between the cap and the rotating ring can be realized. When the cap is screwed on, the rotating ring can move up and down. The rotating ring guide groove 201 or the rotating ring protrusion is provided on the outer wall of the rotating ring 2. The rotating ring guide groove 201 is spirally arranged along the outer wall of the rotating ring 2, and the rotating ring positioning rib 202 is provided on the inner wall of the rotating ring 2. By providing a protrusion and cooperating with the spiral guide groove, the rotating ring 2 can move up and down inside the outer bottle 1.

[0021] The connecting and limiting component further includes an outer bottle limiting point 102 and an outer bottle fastening rib 103. Both the outer bottle limiting point 102 and the outer bottle fastening rib 103 are located at the bottom end of the outer bottle 1. The outer bottle limiting point 102 is located on the inner wall of the outer bottle fastening rib 103 and is symmetrically distributed along the outer bottle fastening rib 103. The rotating limiting component further includes a cap fastening rib 301, a cap fastening groove 302, and a cap limiting rib 303. The cap fastening groove 302 is located between the base and the cap plate. The cap fastening rib 301 is located on the inner wall of the cap plate. The cap limiting rib 303 and the cap positioning rib 304 are located on the outer wall of the cap plate. The outer bottle limiting point 102 and the cap limiting rib 303 are connected in conjunction. The outer bottle fastening rib 103 is connected in conjunction with the cap fastening groove 302. The fastening rib at the bottom of the inner bottle 4 is linked to the cap fastening rib 301. The cap positioning rib 303 is linked with the outer bottle limiting point 102. Its main function is to deform and squeeze inward after the linkage, and finally the cap fastening rib 301 and the inner bottle fastening rib 8 are fastened together. See the inner bottle bottom fastening rib for details. Figure 7 This mechanism secures the inner bottle, and rotating the cap in the opposite direction unlocks and releases the locking mechanism.

[0022] The outer bottle guide rail groove or rotating ring guide rail groove 201 includes a bottom end and a top end, both of which are provided with buckles. By providing buckles, a locking force can be provided after clamping, while also limiting the movement range of the rotating ring.

[0023] The assembly method of the container in this application is as follows: (Refer to...) Figure 8 First, insert the outer bottle protrusion 101 into the rotating ring guide groove 201 and rotate it to the bottom. The bottom of the cap positioning rib 304 and the rotating ring positioning rib 202 are positioned and matched. Then, press the cap snap-fit ​​groove 302 and the outer bottle snap-fit ​​rib 103 into place. After assembly, the snap-fit ​​is completed. After fixing, the cap positioning rib 303 and the outer bottle protrusion 102 can be linked according to the rotation of the cap to complete the assembly of the main structure of the product.

[0024] Refer to Figure 5 and Figure 6 The working principle of the replaceable inner bottle container of this application is as follows: The rotating ring and the cap positioning linkage structure are used to rotate the cap in one direction to its bottom position. At this time, the outer bottle protrusion 101 is located at the bottom limit of the rotating ring guide groove 201, and the rotating ring moves upward. After the rotating ring moves to the bottom (the maximum upward distance of the rotating ring is the height of the rotating ring guide groove 201), it will abut against the bottom surface of the cap located on the upper part of the inner bottle. At this time, the cap is limited and there is no further downward pressure space. Figure 5 The closed state shown achieves its protective function by restricting the cap. Simultaneously, the outer bottle limiting point 102 and the cap limiting rib 303 are in contact, and the cap locking rib 301 can engage with the locking rib at the bottom of the inner bottle structure. The entire structure is in a closed, locked, and protected state. When the inner bottle is locked, it cannot be moved up or down or removed, and the cap of the pressing structure on top of the inner bottle cannot be pressed or used. Therefore, in this state, the cap on top of the inner bottle cannot be pressed or extended, and the inner bottle is protected and locked, preventing removal.

[0025] When the cap is screwed down in the opposite direction, the outer bottle limiting point 102 and the cap limiting rib 303 are not in contact. The cap latch 301 can deform and spring back when the inner bottle structure is pulled out. The rotating ring is screwed to the bottom, the overall structure is open, and the protective lock is released. Figure 5 The open state shown and Figure 6 The replaceable state shown indicates that the rotating ring is moving downwards. After the rotating ring moves downwards (at this time, the outer bottle protrusion 101 is located at the top limit of the rotating ring guide groove 201), the bottom surface of the cap on the upper part of the inner bottle is not limited by the rotating ring, creating a pressing space (the pressing space corresponds to the height of the rotating ring guide groove, i.e., the maximum distance of the pressing space is the same as the height of the rotating ring guide groove). At this time, the cap of the pressing structure on the upper part of the inner bottle can be pressed or extended / retracted, and the inner bottle can also be removed. That is, the locking or replacement of the inner bottle and the pressing and locking of the cap are achieved by the up-and-down movement of the rotating ring.

[0026] This application provides a container with a replaceable inner bottle. Many methods and approaches exist to implement this technical solution. The above description is merely a preferred embodiment of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application. All components not explicitly stated in this embodiment can be implemented using existing technology.
