Description

[0001] The present application is a divisional application of CN201811254561.9 filed on October 26, 2018, which is a valve spout cover. TECHNICAL FIELD

[0002] The present application relates to a container closure, in particular to a valve spout cover. BACKGROUND

[0003] Some spout covers connected to containers on the market adopt a straight-through structure, when pouring the contents of the container, the contents flow directly out of the spout cover without the need for pressurization, and if the outer cover is not covered, the inner cavity of the container is always in communication with the outside world, so it cannot automatically block the liquid outlet of the spout cover immediately after pouring, thus easily contaminating the unused contents in the container or causing them to deteriorate.

[0004] In addition, after the container is filled, an aluminum foil or the like needs to be added for sealing when covering the cover, and when using, the cover needs to be opened first and then the aluminum foil is torn off. Due to the addition of the aluminum foil packaging process, the packaging cost is high, and the unpacking is complicated.

[0005] Furthermore, the container should be ensured to be in a fully sealed state before use, which can be achieved by adding a sealing sheet, but the cost is high; another is to design the cover with an integrated sealing structure, which can save cost, but cannot guarantee that it can still be dustproof and sealed after unpacking. Therefore, a cap needs to be added, and if a flip cover is made, it is difficult to do so because it needs to be able to be torn off from the mouth and made into a flip cover, which may not be covered or not fully covered.

[0006] The present application is proposed to overcome the deficiencies of the prior art. SUMMARY
