Description

Cover of container

The utility model relates to a kind of container lid, has more the leakproof seal effect for a kind of, and the container lid that is more convenient for recycling.

Because the material of conventional container body is different with the material of its lid, so when the classification returnable, cause cooresponding puzzlement.Please referring to shown in Figure 1, the container lid of commonly using comprises that mainly a body of the bottle lid 20, one anti-drain gaskets 22 are contained in this body of the bottle lid 20 the insides.This body of the bottle lid 20 has a closed end 21 and an open end, and its inside is provided with negative thread 23 can be for the solid top to container of spiral shell.This container lid often can't cover container massively, makes the air, particularly carbon dioxide of receptacle be easy to and can effusion go.Moreover, it is made by alumina based material that this kind commonly used body of the bottle lid system, when opening body of the bottle lid, certain some of this container lid can be deposited in above the container, so when classification is reclaimed, must earlier this alumina based material be got rid of just passable, the program that it must increase by this alumina based material of removal causes sizable puzzlement.

The purpose of this utility model is to provide a kind of container lid, and it can provide better leakproof seal effect to container, and it can more conveniently do the work that classification is reclaimed.

The purpose of this utility model reaches as follows: a kind of container lid, comprise a body of the bottle lid, this body of the bottle lid has a caping and an open end, and its inside is provided with negative thread, the bottom of this body of the bottle lid is provided with the buckle element that fastens bottleneck, it is characterized in that:

This body of the bottle lid is provided with an annular flange at the medial surface of its caping, and the bottom of this annular flange is one can push against the edge that supports above the bottleneck of container, is provided with an outstanding outward curved arc position in this middle part of supporting edge.

Effect of the present utility model is: body of the bottle lid of the present utility model is identical with the employed material of this container, make its do classification reclaim quite convenient.Moreover, this annular flange support the bottleneck that edge can positively push against this container, make the utility model can form sealing state really.

For further specifying structure of the present utility model, feature and practical purpose thereof, the following drawings describes in detail as the back:

Fig. 1 is the exploded drawings of the container lid commonly used;

Fig. 2 is the three-dimensional cutaway view of container lid of the present utility model; And

Fig. 3 is the amplification view of container lid of the present utility model.

Container lid of the present utility model please cooperate and consult Fig. 2 and shown in Figure 3, comprises a body of the bottle lid 11, and it has a closed end or a caping 13 and an open end, and its inside is provided with a negative thread 12 can be for solid bottleneck 14 places to container of spiral shell.This body of the bottle lid 11 can be made for plastics, make this body of the bottle lid 11 can with the container recovery of classifying together.The bottom of this body of the bottle lid 11 is provided with many buckle elements 15 can make this body of the bottle lid can secure to the bottle mouth position of this container for an annular shoulder 16 that fastens bottleneck 14.

This body of the bottle lid 11 is provided with an annular flange 10 at the medial surface of its caping 13, the bottom of this annular flange be one support edge 101 can be for pushing against above the bottleneck 14 of container, to form the leak free state.Wherein, the end 102 that should support edge 101 was inclined, made that should support edge 10 can have suitable elasticity and can push against above container finish, to form the leak free structure.In addition, be provided with one in this middle part of supporting edge 101 and slightly be outstanding outward curved arc position 103, make this support edge 101 and have more elasticity and can have more flexible degree.That is, when between the caping 13 of container finish 14 and body of the bottle lid a little different the time, should support that edge 101 still can be flexibly crooked and the bottleneck that can push against any container.When this container is used for ccontaining beverage with forced air, for example soda the time, this supports edge 101 even if this forced air applies pressure to, the curved arc position 103 that should support edge can be resisted against the medial margin of this body of the bottle lid and can still can make it still can keep the leak free state effectively tightly against this bottleneck 14 so that should support edge 101.

Claims (1)

1, a kind of container lid comprises a body of the bottle lid, and this body of the bottle lid has a caping and an open end, and its inside is provided with negative thread, and the bottom of this body of the bottle lid is provided with the buckle element that fastens bottleneck, it is characterized in that:

This body of the bottle lid is provided with an annular flange at the medial surface of its caping, and the bottom of this annular flange is one can push against the edge that supports above the bottleneck of container, is provided with an outstanding outward curved arc position in this middle part of supporting edge.
