Plastic bottle cap

Abstract

The invention discloses a plastic bottle cover which can change liquid output flow. The plastic bottle cover comprises a cover seat, wherein the cover seat is provided with a cover body which can be fastened with the cover seat, and the cover seat is also internally provided with a connecting opening which is connected with a bottle opening; the technical scheme of the plastic bottle cap is mainly characterized in that the cover seat is provided with a convex column, the convex column is internally provided with a convex column hollow cavity which is communicated with the connecting opening, the side wall of the convex column is provided with an inner liquid outlet which is communicated with the convex column hollow cavity, the convex column is covered with an inner cover which can rotate around the convex column, and the side wall of the inner cover is provided with an outer liquid outlet which can be overlapped or staggered with the inner liquid outlet; the outer liquid outlet comprises a big outer liquid outlet and a small outer liquid outlet of which the areas are different, the outer liquid outlet is provided with inclined lip-shaped pieces protruding the side surface of the inner cover, the overlap area between the outer liquid outlet and the inner liquid outlet can be changed along with the rotation of the inner cover, and the liquid outlet flow can be controlled by rotating the inner cover. According to the plastic bottle cover disclosed by the invention, the cover body can be separated from the cover seat in 0-180 degrees, and the liquid can be conveniently poured.

Description

【Technical field】 [0001] The invention relates to a plastic bottle cap, in particular to a plastic bottle cap capable of changing the flow rate of liquid. 【Background technique】 [0002] In the plastic bottle caps of the prior art, the inner liquid outlet on the cap seat has a certain distance from the edge of the cap seat. When the liquid is poured out, the liquid is easily dumped on the cap seat, polluting the cap seat and the bottle mouth; on the other hand, The size of the inner liquid outlet on the cover seat is constant, and the flow that it pours out is not easy to control, especially when a plastic bottle filled with liquid pours out a small flow of liquid, it is easy to pour out more. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a plastic bottle cap capable of controlling the flow of poured liquid and not polluting the cap seat by pouring it into the cap seat. [0004] The presen...
