Abstract

A cover includes a hollow base, a stop member, a partition, a hollow operating member and an outer cover. The hollow base is combined with a mouth of a container. The partition and the stop member are arranged in the hollow base. The partition cooperates with the hollow base to form a plurality of quantitative spaces, and the stop member can correspondingly close one side of any quantitative space. The hollow operating member is rotatably sleeved on the hollow base and drives the partition to rotate to change the positions of the plurality of quantitative spaces. The outer cover is pivotally connected to the hollow operating member to be in an open or closed state. When the outer cover is in the closed state, the quantitative space closed correspondingly by the stop member forms an independent closed space, and the independent closed space can be formed by any quantitative space by rotating the hollow operating element. When the outer cover is in the open state, the contents in the independent closed space can be released.

FIG. 7 is a cross-sectional view of the cover of the present invention during operation, and FIG. 8 is another cross-sectional view of the cover of the present invention during operation. As shown in FIG. 7, for example, the lid 1 of the present invention is combined with a container A, and the container A stores a powdery substance. In the initial state, the outer cover 50 is in a closed state relative to the hollow operating member 40, and the user can rotate the hollow operating member 40 at will to drive the locking member 60 and the stirring member 70 to rotate. In order to scrape off the powdery substance remaining on the inner wall of the container A and make the powdery substance of the container A uniform and not easy to agglomerate. Then, after the hollow operating member 40 is rotated to the position, the user can turn the container A upside down, so that the powdery substance of the container A is guided by gravity to pass through the stopper 20, and then fill in the non-stopper 20. The stop 21 encloses one or more quantitative spaces S. That is to say, in this embodiment, at this time, there will be two quantitative spaces S that are not closed by the stopper 21 of the stopper 20 to allow a quantitative powdery substance to be filled, and the other quantitative space S will be due to the two The sides are respectively closed by the stopper 21 of the stopper 20 and the outer cover 50 to form an independent enclosed space S1 without any powdery substance. Under the condition that the container A continues to be inverted, the user rotates the hollow operating member 40 again, which will drive the partition 30 to rotate, causing the three quantitative spaces S to change their respective positions until the hollow operating member 40 is rotated to position. One of the accommodating spaces S filled with powdered substances will form a new independent enclosed space S1 because the two sides are respectively closed by the stopper 21 of the stopper 20 and the outer cover 50, and the original independent enclosed space Because the closure on one side of the stopper 20 (that is, the stop portion 21 of the stopper 20) is released, it becomes a quantitative space S that can be filled with powdery substances.

As shown in FIG. 8, at this time, if the user rotates the outer cover 50 relative to the hollow operating member 40 to be in an open state, the side of the independent enclosed space close to the outer cover 50 will be unclosed, making the independent enclosed space The powdery substance is released through the opening 411 of the top end 41 of the corresponding hollow operating member 40 and the releasing hole 112 of the hollow base 10 to achieve the effect of releasing a quantitative powdery substance. By analogy, if the user needs it, the aforementioned operations can be performed repeatedly under the condition that the container A is kept inverted continuously, so that a certain amount of powdery substance can be released for each operation.

To sum up, the cover of the present invention, through the design of the quantitative space, can release a quantitative content each time the container is used with a simple operation, which greatly improves the convenience and flexibility of the user.
