Therefore, when taking the container, you must be careful that the lid is easy to fall off. If you take it carelessly, once the lid is separated from the container, it is easy to make the entire container fall .

Contents of the invention

The main purpose of the utility model is to provide a container bung cover, which can easily achieve the purpose of opening the cover by virtue of the separate combination of the cover and the inner cover, and can be screwed with the container by virtue of the inner cover. Fixing can achieve a good sealing effect and leak-proof effect on the container.

For realizing above-mentioned object, the technical scheme that the utility model adopts is:

A container bung cover, characterized in that it is composed of a container, an inner plug cover and a cylinder cover, wherein: an inner plug cover is inserted into the container opening, and the cylinder cover is arranged on the outer edge of the container opening, The inner edge of the cover is provided with more than two internal threads, and the outer edge of the container opening is provided with more than two threads, so that the cover and the container can be screwed and fixed with each other.

Preferably, the above technical solution can also have the following technical features:

The cover is integrally connected with a tear ring, and the inner edge of the tear ring has a convex rib, and the tear ring of the cover is tightly combined in the fixing groove on the opening edge of the container, and the protrusion The rib is buckled at the fixing groove.

Compared with the prior art, the utility model adopting the above-mentioned technical solution has the advantages of: the purpose of opening the lid can be easily achieved by virtue of the separate combination of the lid and the inner plug lid, and the inner lid can be connected with the container It is fixed in the way of screw lock, which can achieve a good sealing effect and leak-proof effect on the container.

Detailed ways

In order to make the technical content and principle used by the present utility model easy to understand, the specific embodiments are illustrated as follows, but it does not limit the scope of the present utility model. Those familiar with the art can easily understand the utility model from the content disclosed in this manual. The advantages and effects of the new model, the utility model can also be implemented or applied by virtue of other different specific embodiments. The details in this specification can be based on different viewpoints and applications, without departing from the spirit of the utility model. Modifications and changes.

Please refer to Fig. 1 to Fig. 4, the container bung cover of the present utility model mainly includes a container 1, an inner plug cover 2 and a barrel cover 3, wherein the inner plug cover 2 is mainly provided at the opening 11 of the container 1 With the cylinder cover 3, the opening 11 of the container 1 is plugged with an inner plug cap 2. The inner plug cap 2 is integrally formed and provided with a plugging portion 21, wherein the downwardly protruding plugging portion 21 is connected to the opening 11. It is in a tight fit state between them, and the upper edge of the inner plug cover 2 can just be arranged above the opening 11, and can be locked and fixed with the inner edge of the container 1.

Referring again to Fig. 3 to Fig. 6, the described cap 3 is arranged on the outer edge of the opening 11 of the container 1, and the inner edge of the tear ring 32 integrally connected with the cap 3 has a rib 322, when the cap 3 covers When it is closed at the opening 11, the tear ring 32 of the cylinder cover 3 can be tightly combined in the fixing groove 13 on the edge of the opening 11 of the container 1, and is buckled at the fixing groove 13 with the convex rib 322 inside it, so as to The container 1 and the cylinder cover 3 will be closed tightly.

Please refer to Fig. 5 to Fig. 7, the above-mentioned cap 3 is fixed behind the container 1 so that the contents contained in the container 1 are preserved through the leak-proofing of the inner plug cap 2 and the fixing of the cap 3 . When opening the cover 3, the tear ring 32 on the tear ring 32 is completely torn off, so that the cover 3 can be opened; It can be screwed and fixed with the screw thread 12 at the opening 11 of the container 1, so that the cylinder cover 3 will not be easily loosened from the container 1.

In summary, the container bung cover of the present utility model has a structure that is easy to be screwed and opened, and two to four threads are used to lock and open each other, which is very convenient in opening and screwing, and can achieve It is not loose and the inner plug cap is used to achieve the sealing effect.
