Preferably, an annular raised portion is provided above an outer diameter of the rotating base, and the raised portion is buckled in an annular groove in the inner wall position below the outer bottle.

Preferably, the center of the rotating base is provided with a rotation stopper hole, and a keyway is defined at an inner wall of the rotation stopper hole along an axial direction thereof, and the keyway is matched and connected with a rectangular bulge at the outer wall of the circular boss below the screw.

The invention has the beneficial effects that:

The invention presents a simple design structure and is convenient to use, in which the inner container can be separately designed from the outer bottle, and the inner container can be removed after use with a reusing function of an outer bottle remained, so as to reduce pollution to the environment, optimize a structure of the product, and reduce loss in a component.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to make the purpose, technical scheme and advantages of the invention clearer, the technical scheme of the invention will be described in detail in the following. Obviously, the described embodiments are only a part of the embodiments of the invention, not all of them. On the basis of the embodiments of the invention, all other embodiments obtained by ordinary skilled in the art without creative labor fall in the scope protected by the invention.

As shown in the figures, the invention provides a rotary bottle with a replaceable inner container, which comprises an outer bottle1, an inner container9and a rotating base, in which an upper cover12is removablely attached above the outer bottle1, a rotating base5is rotatably attached below the outer bottle1, and the inner container9is coaxially installed at an inner position of the outer bottle1, an inner cover11is installed above the inner container9, a clamping point13protruding outwards is arranged at a outer wall position of the inner container9, and is correspondingly clamped in a groove at an inner wall of the outer bottle1so that the inner container9and the outer bottle1can be kept relatively stationary without effect of an external force, and the shaking between the inner container9and the outer bottle1can be avoided; a screw10is arranged in an inner position of the inner container9, an upper clamping ring7connected with the inner container9is arranged in a position, close to a circumferential edge, of an upper surface of a bottom of the screw10, the upper clamping ring7is clamped in an annular groove in an inner wall position of the inner container9, and a bottom plug6is installed in a position between a lower surface of the bottom of the screw10and the rotating base5, the bottom plug6is clamped on a lower clamping ring2in a position, close to the circumferential edge, of the lower surface of the bottom of the screw, and a circular boss3is provided in a center position of the lower surface of the screw10and is synchronously rotatably connected with the rotating base5.

Specifically, an external thread is arranged on the upper outer wall of the outer bottle1, and the upper cover12is connected to an external thread position of the outer bottle1through threads, so that the removable connection of the upper cover12can be realized in which the upper cover12can be removed when in use and it is convenient to use.

Specifically, the inner cover11is buckled above the inner container9, and in use, the inner cover11can be detached by pulling the inner cover11upward.

Specifically, the screw10is threaded with a threaded sleeve8, and the outer wall of the threaded sleeve8is tightly attached to the inner wall position of the inner container9, so that the sealing effect can be realized and when the screw10rotates, the threaded sleeve8can move up and down along the axial direction thereof in the inner container9.

Specifically, an annular raised portion is provided in a position above the outer diameter of the rotating base5, and the raised portion is buckled in an annular groove at the inner wall position below the outer bottle1, so that a relative rotation between the rotating base5and the outer bottle1can be realized, and the both are kept relatively stationary in the axial direction during the rotation.

Specifically, the center position of the rotating base5is provided with a rotation stopper hole4, and a keyway is defined at the inner wall of the rotation stopper hole4along an axial direction thereof, and the keyway is matched and connected with a rectangular bulge14at the outer wall of the circular boss3below the screw10, so that when the rotating base5and the outer bottle1are relatively rotated, the rotating base5can drive the screw10to rotate, and the screw10drives the threaded sleeve8to move up or down along the axis of the inner container9while rotating.

Working principle: a cosmetic paste (e.g. deodorant paste, facial cleanser, etc.) is placed inside the inner container9, and when in use, the upper cover12is opened, the inner cover11is opened, and the rotating base5is rotated to drive the screw10to rotate, and the screw10drives the threaded sleeve8connected therewith to move upwards while rotating, thus pressing the paste inside the inner container9to move upwards; then users can use the paste to make up, and when the paste inside the inner container9is used up, the inner container9can be detached and replaced with a new inner container9, after which the outer bottle1and the rotating base5can be reused, so as to achieve the purpose of recycling, reduce the pollution to the environment, optimize the product structure and reduce loss in a component.

In the other embodiment, as shown inFIG. 3, a tubular shaped wall15is set around the screw, one end of the tubular shaped wall15is fixedly connected to the lower clamping ring, and a channel is set within the threaded sleeve8to accommodate the tubular shaped wall15so that the tubular shaped wall15and threaded sleeve8are rotatably connected. With this setting, the cosmetic past in inner container9will not come into direct contact with the tubular shaped wall, thus reducing the waste of cosmetic past. Alternatively, the end of the tubular shaped wall can be fixedly connected to a middle part16of the threaded sleeve8as shown inFIG. 4. Alternatively, a middle part of the threaded sleeve8can be extended upward to a top of the screw as shown inFIG. 5.

The above is only specific embodiments of the invention, but the protection scope of the invention is not limited to this; changes or substitutions can be easily contemplated by any person familiar with the art within the technical scope disclosed by the invention, and should be covered within the protection scope of the invention. Therefore, the protection scope of the invention shall be subject to that of the claims.
