[0057] To make the objectives, technical solutions, and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art. Example

[0058] like Figures 1-12 As shown, a container lid includes an outer lid 1 and an inner plug 2. The outer lid 1 is screwed onto the container opening 9, and a through hole is provided at the top of the outer lid 1. The inner plug 2 is integrally formed from a hollow platform 3 and a hollow column 4. A pressure block 5 with a diameter larger than the diameter of the through hole of the outer lid 1 and the inner diameter of the container opening 9 is provided circumferentially on the hollow platform 3. The pressure block 5 is pressed and fixed to the end face of the container opening 9 by the outer lid 1. In use, the inner plug 2 can be removed by unscrewing the outer lid 1. The bottom of the hollow column 4 of the inner plug 2 is provided with an inner cover 7 through a thin section 6, which can be used to seal the broken end of the thin section 6. In use, the thin section 6 can be broken off, and then the inner cover 7 can be used to seal the broken end of the thin section 6. The opening is sealed to ensure a good seal. The inner cover 7 has a small inner plug 8 inside that can be used to seal the cavity of the column. When the inner cover 7 is used to seal the broken part 6, the small inner plug 8 can be inserted into the broken cavity of the hollow column 4 for further sealing. The outer cover 1, inner cover 7 and small inner plug 8 form multiple seals to ensure that the liquid will not flow out from the container opening 9. The sealing effect is good. Moreover, when the liquid is poured out, the liquid will flow out directly and will not remain on the container cover. After use, the liquid that is not poured out at the container cover will also flow back into the container. It will not contaminate the user's hands during subsequent use and is extremely convenient to use.

[0059] Preferably, the pressing block 5 is provided with a clamping position for cooperating with the outer cover 1 at the connection with the inner plug 2, so that the inner plug 2 can be better sealed between the container mouth 9 and the outer cover 1, ensuring the sealing property.

[0060] Use process:

[0061] In use, the hollow column 4 is initially downward, the inner plug 2 and the clamping position are wrapped inside the container mouth 9, and the liquid cannot flow out. When the user uses it, the outer cover 1 must be opened first, the inner plug 2 is inverted, then the outer cover 1 is covered and screwed, and the hollow column 4 is pressed upward by the outer cover 1. Then the thin position 6 is broken, the liquid in the inside flows out from the hollow column 4 through the container mouth 9, if the liquid cannot be used at one time, the broken inner cover 7 is covered, and the small inner plug 8 blocks the inner cavity of the hollow column 4, so that the liquid cannot flow out.

[0062] The inner plug 2 and the inner cover 7 are connected by the thin position 6, and the inner cover 7 is convenient to break off from the inner plug 2. When the original sealing is performed, the inner plug 2 is integrally inverted and screwed on the container mouth by the thin position 6 connecting the inner plug 2 and the inner cover 7 together, and there is no outlet on the whole container cover, so that the liquid in the container cannot flow out from the inner plug 2. When the container is opened, the inner plug 2 is inverted, the hollow column 4 of the inner plug 2 can be used as a liquid outlet to guide the liquid, and after use, the inner cover 7 can be directly inverted to seal the broken part of the thin position 6, so that the remaining liquid in the container can be better stored. This design can not only ensure the sealing property before opening, but also can ensure that the remaining liquid in the container can be better sealed and stored after opening. Embodiment

[0063] As Figures 13-21As shown, a container cover comprises an outer cover 1 and an inner plug 2, the outer cover 1 and the inner plug 2 are integrally formed, the outer cover 1 is screwably arranged on a container mouth 9, the inner plug 2 is located in a cavity of the outer cover 1 and has a hollow structure, one end of the inner plug 2 extends out of a lower end surface of the outer cover 1 and can be tightly clamped with an inner cavity of the container mouth 9, the other end is in the shape of a thin bottle mouth 9, and a small inner plug 8 for sealing a cavity of the end of the inner plug 2 is connected to the end surface through a thin position 6, in use, the thin position 6 needs to be broken, and the small inner plug 8 can be used to seal the broken part of the thin position 6 to ensure the sealing property. The structure design is extremely convenient to use, and before opening, the outer cover 1 and the inner plug 2 are integrally screwed on the container mouth 9, because the inner plug 2 and the small inner plug 8 are integrally connected, liquid cannot flow out, and the sealing property is good, when opening and using, the outer cover 1 and the inner plug 2 are first inverted as a whole, the inner plug 2 is tightly clamped with the inner cavity of the container mouth 9, to ensure that liquid cannot flow out from the clamped part during use, after use, the small inner plug 8 is inserted into the broken part of the thin position 6 to seal the cavity of the inner plug 2, to ensure that the remaining liquid can be stored in a sealed manner. In addition, the container cover designed in this way can make liquid flow out directly when pouring, and liquid will not be left on the container cover, after use, the liquid not poured out from the container cover will also flow into the container, and will not contaminate the user's hands during subsequent use.

[0064] Preferably, the small inner plug 8 is circumferentially provided with a limiting table 10 for sealing the broken part of the thin position 6, the limiting table 10 can not only seal the broken part of the thin position 6, but also can prevent the small inner plug 8 from being pressed into the container.

[0065] Use process:

[0066] In use, the small inner plug 8 is downward in the initial state, the outer cover 1 wraps the container mouth 9 in the middle of the outer cover 1, and liquid cannot flow out. When the user uses it, the outer cover 1 is first inverted to tightly clamp the inner plug 2 with the container mouth 9, the small inner plug 8 is upward, then the small inner plug 8 on the outer cover 1 is broken at the thin position 6, the liquid inside flows out from the cavity of the inner plug 2 through the container mouth 9, if the liquid cannot be used at one time, the broken small inner plug 8 is covered, and the liquid cannot flow out.

[0067] The small inner plug 8 and the inner plug 2 are connected by the thin position 6, and the small inner plug 8 is convenient to break off from the inner plug 2, when sealing, the thin position 6 integrally connects the inner plug 2 and the outer cover 7 together, the container cover is inverted and screwably arranged on the container, there is no outlet on the whole container cover, therefore liquid in the container cannot flow out from the inner plug 2, when opening and using, the inner plug 2 is reversely clamped with the container mouth, the small inner plug 8 is broken off, the inner plug 2 can be used as a liquid outlet and play a role of guiding liquid, and after use, the small inner plug 8 can be reversely sealed to the broken part of the thin position 6, to ensure that the remaining liquid in the container can be better stored. The design can not only ensure the sealing property before opening, but also can ensure that the remaining liquid in the container can be better stored after opening. Example

[0068] like Figures 22-27 As shown, a container cap includes an outer cap 1 and an inner plug 2. The outer cap 1 and the inner plug 2 are integrally formed. The outer cap 1 is screwed onto the container opening 9. The inner plug 2 is located inside the outer cap 1, and the upper end of the inner plug 2 is a hollow structure that can be fitted into the container opening 9. A hollow column 4 with a through hole is provided inside the inner plug 2. The top of the hollow column 4 is connected to an inner cap 7, which can be used to seal the hollow column 4, through a thin section 6. The thin section 6 can be broken off, allowing the inner cap 7 to separate from the inner plug 2. Before opening, the outer cap 1 is screwed onto the container opening 9, and the inner cap 7 and the inner plug 2 are integrally connected, preventing liquid from flowing out of the container opening 9, thus providing good sealing. After use, the inner plug 2 can be inverted to seal the broken end of the thin section 6 of the hollow column 4, ensuring that the remaining liquid can be sealed and stored, making it extremely convenient to use. When liquid is poured out, the liquid flows straight out without leaving any residue on the lid. After use, any liquid that is not poured out will also flow back into the container, preventing contamination of the user's hands during subsequent use.

[0069] Preferably, the inner diameter of the inner cover 7 matches the outer diameter of the hollow column 4, so that the inner cover 7 can fit tightly with the thin section 6 of the hollow column 4 to ensure its sealing effect.

[0070] Usage process:

[0071] In use, the inner cover 7 faces upwards initially, with the outer cover 1 covering the container opening 9 in the middle, and the inner plug 2 blocking the container opening 9, preventing liquid from flowing out. When the user uses it, they first break off the small inner plug 8 on the inner plug 2 at the thin part 6, and the liquid in the container flows out through the hollow column 4. If the liquid cannot be used up at once, the broken inner cover 7 is put back on, and the liquid will no longer flow out.

[0072] This invention connects the inner plug 2 and the inner cover 7 by setting a thin section 6. The inner cover 7 is easily pried off from the thin section 6. When originally sealed, because the thin section 6 integrally connects the inner plug 2 and the inner cover 7, the inner plug 2 is screwed onto the container opening, and there is no outlet on the entire container cover. Therefore, the liquid inside the container will not flow out from the inner plug 2. When opening for use, the inner cover 7 is broken off from the thin section 6, allowing the hollow column 4 of the inner plug 2 to serve as a liquid outlet, acting as a liquid guide. After use, the inner cover 7 can be directly reversed to seal the broken end of the thin section 6, ensuring better storage of the remaining liquid in the container. This design not only ensures the seal before opening but also ensures better sealing and storage of the remaining liquid in the container after opening. Example

[0073] like Figures 28-33As shown, a container cover, comprising an outer cover 1 and an inner plug 2, the outer cover 1 is screwed on the container mouth 9, a through hole is formed on the top of the outer cover 1, the outer cover 1 seals the outside of the container mouth 9, the inner plug 2 is integrally formed by a hollow platform 3 and a hollow column 4, the hollow platform 3 is sealingly inserted into the container mouth 9, the hollow platform 3 seals the inside of the container mouth 9, the hollow platform 3 is circumferentially provided with a snap ring 11 for cooperating with the end face of the container mouth 9, the snap ring 11 can prevent the inner plug 2 from being pressed into the container, the hollow column 4 extends out of the through hole of the outer cover 1, and the upper end face of the hollow column 4 is sealingly inserted with an inner cover 7, the inner cover 7 is connected with the outer cover 1 through a thin part 6, the distance between the upper end face of the inner plug 2 and the inner end face of the outer cover 1 is greater than the width of the thin part 6, in use, the outer cover 1 can be turned, so that the outer cover 1 is screwed with the container mouth 9, and the support force of the container mouth 9 on the inner plug 2 makes the inner cover 7 and the outer cover 1 separate at the thin part 6, after use, the inner cover 7 seals the hollow column 4, this design, before opening, the outer cover 1 and the inner cover 7 are integrally connected, the sealing effect is good, and the outer cover 1 and the container mouth 9, the inner plug 2 and the container mouth 9 are each sealed once more, liquid cannot flow out, and the remaining liquid after use can also be stored.

[0074] Preferably, the inner cover 7 is provided with a small inner plug 8 for plugging the hollow cavity of the hollow column 4, when the inner cover 7 seals the hollow column 4, the small inner plug 8 will be inserted into the hollow column 4, and the small inner plug 8 further seals the hollow column 4 to ensure the sealing performance.

[0075] Use process:

[0076] In use, the initial state is that the inner cover 7 and the outer cover 1 are connected by the thin part 6, the outer cover 1 wraps the container mouth 9 in the middle of the outer cover 1, the inner plug 2 plugs the container mouth 9, the top of the container mouth 9 is limited by the snap ring 11 of the inner plug 2, and the top of the hollow column 4 of the inner plug 2 is limited by the inner cover 7, liquid cannot flow out. When the user uses it, hold the container and rotate the outer cover 1, the outer cover 1 is screwed with the container mouth 9, the outer cover 1 rotates downward, the top of the container pushes the inner plug 2, the hollow column 4 of the inner plug 2 breaks the thin part 6 between the inner cover 7 and the outer cover 1, the outer cover 1 and the inner cover 7 are separated, and the liquid inside flows out through the hollow column 4, if the liquid cannot be used at one time, cover the broken inner cover 7, and the liquid cannot flow out.

[0077] This invention connects the outer cover 1 and the inner cover 7 by setting a thin section 6. The inner cover 7 is easily pried off from the thin section 6. When originally sealed, the thin section 6 connects the outer cover 1 and the inner cover 7 as a single unit. The outer cover 1 is screwed onto the container opening, and the inner cover 7 presses against the inner plug 2. The small inner plug 8 precisely seals the hollow column 4 of the inner plug. Since there is no outlet on the entire container lid, the liquid inside the container will not flow out from the inner plug 2. When opening for use, simply rotate the outer cover 1; the hollow column 4 will break the inner cover 7 off at the thin section 6, allowing the hollow column 4 of the inner plug 2 to serve as a liquid outlet. After use, the inner cover 7 can be directly snapped back onto the broken end of the thin section 6 to ensure better storage of the remaining liquid in the container. This design not only ensures a tight seal before opening but also ensures better sealing and storage of the remaining liquid after opening. Example

[0078] like Figures 34-38 As shown, a container lid includes an outer lid 1 and an inner plug 2. The outer lid 1 is screwed onto the container opening 9. The inner plug 2 is integrally formed with the outer lid 1. A hollow column 4 is disposed inside the inner plug 2. A small inner plug 8 is connected to the end of the hollow column 4 through a thin section 6. Before opening, the outer lid 1 seals the outside of the container opening 9, and the inner plug 2 provides a secondary seal to the inside of the container opening 9. Moreover, the small inner plug 8 is integrally connected with the hollow column 4. Through three seals, the sealing effect can be guaranteed, preventing liquid leakage. When in use, the thin section 6 needs to be broken off, and the broken small inner plug 8 can be used to seal the broken end of the thin section 6. If there is any liquid left, simply seal the broken end of the thin section 6 with the small inner plug 8. It is extremely convenient to use and has a good sealing effect. In addition, when pouring liquid, the liquid will flow out directly and will not remain on the container lid. After use, any liquid that has not been poured out from the container lid will also flow back into the container, preventing contamination of the user's hands during subsequent use.

[0079] Preferably, the small inner plug 8 is provided with a limiting platform 10 in the circumferential direction for sealing the cross section of the thin section 6. The limiting platform 10 can not only seal the cross section of the thin section 6, but also prevent the small inner plug 8 from being pressed into the container.

[0080] Usage process:

[0081] In use, initially, the inner plug 2 and the outer cover 1 are connected by the thin section 6. The outer cover 1 covers the container opening 9 in the middle, preventing liquid from flowing out. When the user uses the product, they first break off the small inner plug 8 on the outer cover 1 at the thin section 6, allowing the liquid inside to flow out through the hollow column 4. If the liquid cannot be used up at once, the broken small inner plug 8 can be replaced, preventing the liquid from flowing out.

[0082] The present application connects the inner cover 7 and the small inner plug 8 by setting the thin position 6, and the small inner plug 8 is convenient to break off from the thin position 6. When sealing, the outer cover 1 is integrally connected with the inner cover 7 by the thin position 6, the outer cover 1 is screwed on the container mouth, and there is no outlet on the whole container cover, so the liquid in the container cannot flow out from the inner plug 2. When opening, only the small inner plug 8 is broken off from the thin position 6, and the hollow column 4 of the inner plug 2 can be used as a liquid outlet to guide the liquid, and after use, the small inner plug 8 can be directly reversed to seal the hollow column, so as to better store the remaining liquid in the container. The design can not only ensure the sealing before opening, but also better seal and store the remaining liquid in the container after opening.

[0083] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting.
