Description

The utility model relates to a container cover, which is a container cover which has more leakage-proof sealing effect and is more convenient for recycling.

Because the material of the traditional container body and the material of the lid are different, it causes considerable trouble when sorting and recycling containers. Please refer to FIG. 1 , the conventional container cap mainly includes a bottle cap body 20 , and a leakproof gasket 22 is accommodated inside the bottle cap body 20 . The bottle cap body 20 has a closed end 21 and an open end, and a female thread 23 is provided inside to be screwed to the top of the container. Such container lids often fail to securely cover the container, allowing air, especially carbon dioxide, to easily escape from the container. Furthermore, this kind of conventional bottle cap system is made of aluminum material. When the bottle cap body is opened, a certain part of the container cover will remain on the container, so the aluminum must be removed first when sorting and recycling. It is only possible to remove the aluminum material, and it is necessary to add a procedure to remove the aluminum material, which causes considerable trouble.

The purpose of the utility model is to provide a container cover, which can provide a better leak-proof sealing effect on the container, and it can be more convenient for sorting and recycling.

The purpose of this utility model is achieved in the following manner: a container cover, comprising a bottle cap body, the bottle cap body has a cap top and an open end, the inside of which is provided with female threads, the bottom of the bottle cap body There is a buckle element for fastening the mouth of the bottle, which is characterized in that:

The bottle cap body is provided with an annular flange on the inner surface of the top of the cover. Prominent bends.

The effect of the utility model is that: the bottle cap body of the utility model is made of the same material as the container, which makes it quite convenient for sorting and recycling. Furthermore, the abutting edge of the annular flange can be firmly pressed against the bottle mouth of the container, so that the utility model can indeed form a sealed state.

For further illustrating structure of the present utility model, feature and practical purpose thereof, following accompanying drawing is described in detail as follows:

Figure 1 is an exploded view of a conventional container lid;

Fig. 2 is a three-dimensional sectional view of the container lid of the present invention; and

Fig. 3 is an enlarged sectional view of the container lid of the present invention.

The container lid of the present utility model, please refer to Fig. 2 and shown in Fig. 3, comprises a bottle cap body 11, and it has a closed end or cover top 13 and an open end, and its interior is provided with a female screw thread 12 and can be screwed. to the bottle mouth 14 of the container. The bottle cap body 11 can be made of plastic, so that the bottle cap body 11 can be sorted and recycled together with the container. The bottom of the bottle cap body 11 is provided with a plurality of locking elements 15 for fastening an annular shoulder 16 of the bottle mouth 14, so that the bottle cap body can be locked to the bottle mouth of the container.

This bottle cap body 11 is provided with an annular flange 10 on the inner surface of its cap top 13, and the bottom end of this annular flange is an abutting edge 101 which can be used to butt against the bottle mouth 14 of the container to form a sealed seal. state. Wherein, the end 102 of the abutting edge 101 is in an inclined state, so that the abutting edge 10 can have proper elasticity and can be pressed against the top of the bottle mouth of the container to form a sealed structure. In addition, a slightly protruding curved portion 103 is provided in the middle of the resisting edge 101 , so that the resisting edge 101 is more elastic and more stretchable. That is, when there is a little difference between the bottle mouth 14 of the container and the cap top 13 of the bottle cap body, the abutting edge 101 can still be elastically bent and can be pressed against the bottle mouth of any container. When the container is used to hold beverages with pressurized air, such as carbonated beverages, even if the pressurized air pressurizes the abutment 101, the curved portion 103 of the abutment can abut against the bottle cap body. The inner edge can make the abutting edge 101 still tightly abut against the bottle mouth 14, so that it can still effectively maintain a sealed state.
