Detailed Description

In order that the invention may be readily understood, a more complete description of the invention will be rendered by reference to the appended drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-7, this embodiment discloses a check flow high-density bottle cap, which includes: the bottle body 1 is used for containing the internal solution; the elastic cavity 2 comprises an elastic cavity main body 21 and a discharging cavity 22, wherein the elastic cavity main body 21 comprises two cylinders which are mutually communicated, the discharging cavity 22 is in a ring shape and is arranged on the top surface of the elastic cavity 21, and a discharging hole 23 is arranged in the center of the discharging cavity 22; the flip 3, flip are 3 cylindrics, are provided with the recess 31 that corresponds with the shape of elasticity chamber 2 on the top surface, and the bottom of recess 31 is provided with screw structure 32 for screw fixedly with body 1, the top of recess 31 is provided with projection 33, and projection 33 passes through six projection supports 34 and recess 31 fixed connection, forms six fan-shaped holes 35 between six projection supports 34.
