FIELD

The invention relates to a technical field of rotary bottle, in particular, to a rotary bottle with a replaceable inner container.

BACKGROUND

At present, the rotary bottle available on the market comprises a body at a bottom of which a hollow rotating base is provided, and a pushing screw is provided on the rotating base and arranged in a center of the rotating base, and the pushing screw is snap-fastened with the base through an arc rising bar. This type of rotary bottle cannot be reused after use, causing environmental pollution.

SUMMARY

The object of this invention is to provide a rotary bottle with a replaceable inner container, in which the inner container can be separately separated from the outer bottle, and the inner container can be removed after using 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.

In order to achieve the above object, the invention provides the following technical scheme:

The invention provides a rotary bottle with a replaceable inner container, which includes an outer bottle, an inner container and a rotating base, wherein an upper cover is removablely attached above the outer bottle, a rotating base is rotatably attached below the outer bottle, the inner container is coaxially installed at an inner of the outer bottle, an inner cover is installed above the inner container, a clamping point protruding outwards is provided at an outer wall of the inner container, and the clamping point is correspondingly clamped in a groove at an inner wall of the outer bottle. A screw is provide in an inner of the inner container, an upper clamping ring connected with the inner container is provide in a position, close to a circumferential edge, of an upper surface of a bottom of the screw, the upper clamping ring is clamped in an annular groove in an inner wall of the inner container, a bottom plug is installed in a position between a lower surface of the bottom of the screw and the rotating base, the bottom plug is clamped on a lower clamping ring in a position, close to the circumferential edge, of the lower surface of the bottom of the screw, and a circular boss is provided in a center position of the lower surface of the screw and is synchronously rotatably connected with the rotating base.

Preferably, an external thread is arranged on the upper outer wall of the outer bottle, and the upper cover is connected to an external thread of the outer bottle through threads.

Preferably, the inner cover is buckled above the inner container.

Preferably, the screw is threaded with a threaded sleeve, and the outer wall of the threaded sleeve is tightly attached to the inner wall of the inner container.

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.
