Problems solved by technology

After closing the flip cover, if the user wants to open it again, the user's hand will touch the residual liquid on the remaining liquid outlet when opening the flip cover, and touch the residual liquid, causing the user's hands to be polluted. In some cases, you need to wash your hands frequently. The sealing performance of this kind of lid is not good. Another kind is that after the lid is opened, it is separated from the container body. This kind of lid needs to be placed separately. , and then cover it, it is inconvenient to use, and the cover placed alone in other places is not hygienic

Embodiment 1

[0023] Embodiment one, such as figure 1 , 2 Shown; Provide a kind of cover that rotates to open, comprise the lower cover 2 that buckles or screw on the liquid outlet of container, described lower cover 2 has an upwardly arched shell 211, and the middle of arched shell 211 is set There is a tube body 212 protruding downwards, the upper end of the tube body 212 is a through hole, and a sealing piece 12 that can be opened downwards is integrally formed at the lower end of the tube body 212. Internal threads are provided on the inner wall of the tube body 212. Also includes a liquid outlet pipe 1, the outer circumference of the lower part of the liquid outlet pipe 1 is provided with an external thread 5 engaged with the internal thread, and the upper end of the liquid outlet pipe 1 extends from the upper through hole of the pipe body. Outlet, the upper side wall of the liquid outlet pipe is provided with a liquid outlet hole, the edge of the liquid outlet hole is integrally form...

Embodiment 2

[0025] Embodiment two: if image 3 , Figure 4 , as shown, is on the structure of Embodiment 1, a groove can be provided at the bottom of the inner hole of the liquid outlet pipe 1, and a water outlet valve 4 that can be automatically opened under the action of pressure is provided in the groove to increase the water outlet. Valve 4 can prevent the liquid from flowing out automatically when the container is dumped. Only when the container body is squeezed, the liquid will flow out through the elastic water outlet valve. The structure and principle of the elastic water outlet valve have been disclosed and will not be described again.

Embodiment 3

[0026] Embodiment three: as Figure 5 , Figure 6 As shown, on the structure of Embodiment 1, an air inlet 201 is opened on the side of the arched shell 211, and a side of the pipe body corresponding to the air inlet 201 is provided with a An air supply valve 8 that can be automatically opened under pressure, adding an air supply valve 8 can make the liquid flow out more smoothly.

[0027] It is also possible to combine the features of the water outlet valve and the air supply valve in Embodiments 2 and 3. A groove is provided at the bottom of the inner hole of the liquid outlet pipe, and a water outlet valve that can be automatically opened under the action of pressure is provided in the groove. Valve; an air intake hole is opened on the side of the arched shell, and an air supply valve that can be automatically opened under pressure is provided on the side of the pipe body corresponding to the air intake hole. The cover also has the functions of replenishing air and preven...

Abstract

A cover opened through rotation comprises a lower cover body which is buckled to or screwed up to a container liquid outlet. The lower cover body is provided with a shell protruding upwards. The middle portion of the shell protruding upwards is provided with a pipe extending downwards. The upper end of the pipe is provided with a through hole. The lower end of the pipe is integrally provided with a seal sheet capable of being ejected open downwards. Internal threads are arranged on the inner side wall of the pipe. The cover opened through rotation further comprises a liquid outlet pipe. The outer circle of the lower portion of the liquid outlet pipe is provided with external threads meshed with the internal threads. The upper end of the liquid outlet pipe extends out from the upper through hole of the pipe. The side wall of the upper portion of the liquid outlet pipe is provided with a liquid outlet hole. The edge of the liquid outlet hole is integrally provided with a detachable opener. The top end of the liquid outlet pipe is symmetrically provided with a pair of opening handles. When the cover is opened, the liquid outlet function of a container can be achieved just through rotating the liquid outlet pipe. The cover opened through rotation is sanitary in use, good in seal performance and leakage resistance and simple in structure.

Description

【Technical field】 [0001] The invention relates to a container, in particular to a rotatable and open cover arranged at the outlet of the container. 【Background technique】 [0002] In the prior art, the cap of the seasoning bottle provided on the market is a snap-on clamshell structure, which is opened by turning the top cover over. The part where the user opens the clamshell is also the part where the liquid flows out. When the inner liquid is poured out, there will be a little liquid remaining on the liquid outlet part of the bottle cap. After closing the flip cover, if the user wants to open it again, the user's hand will touch the residual liquid on the remaining liquid outlet when opening the flip cover, and touch the residual liquid, causing the user's hands to be polluted. In some cases, you need to wash your hands frequently. The sealing performance of this kind of lid is not good. Another kind is that after the lid is opened, it is separated from the container body....
