Abstract
The novel bottle cap structure that the utility model is provided, including bottleneck and bottle cap, the inner chamber roof of the bottle cap is in inwardly projecting Clothoid type inclined plane shape.In the state of bottle cap and bottleneck closure, the inner chamber roof of bottle cap forms linear contact lay to form liquid-tight envelope with bottleneck inward flange.Compared to prior art, bottle cap roof of the present utility model does not use annular recess, during closed closure, is not required to arduously make the edge of bottleneck to enter in annular recess, so that using laborsaving, convenient.
Description
Technical field
The utility model is related to a kind of novel bottle cap structure.
Background technology
Bottle cap structure includes bottleneck and bottle cap, and in the prior art, bottle cap inner chamber roof is provided with annular recess, bottleneck edge
Mutually it is fitted close with annular recess so as to realize the liquid-tight envelope of bottleneck and bottle cap.However, during closed closure, it is necessary to
With larger power just bottleneck edge can enter in annular recess, to form liquid-tight envelope, cause to use inconvenience.
The content of the invention
The purpose of this utility model is directed to the deficiencies in the prior art, there is provided a kind of novel bottle cap structure, its bottleneck and bottle
Lid easily forms liquid-tight envelope, using convenient.
The novel bottle cap structure that the utility model is provided, including bottleneck and bottle cap, the inner chamber roof of the bottle cap is in inside
Protrusion Clothoid type inclined plane shape, and form linear contact lay with bottleneck inward flange.
Specifically, the inner chamber roof of the bottle cap is spheric or cone-shaped, spheric therein or cone-shaped roof with
Bottleneck inward flange linear contact lay.
Specifically, the inner chamber roof of the bottle cap is the second order surface of revolution, is connected by the taper surface of revolution between the second order surface of revolution
Connect, the taper surface of revolution therein and bottleneck inward flange linear contact lay.
Specifically, bottle cap inner chamber roof is provided with sealed Cellophane, and sealed Cellophane is covered in the surface of the roof.
Specifically, the thickness of the sealed Cellophane is b, 0.5mm≤b≤1mm.
Specifically, bottleneck and bottle cap are connected through a screw thread.
Compared with prior art, the beneficial effects of the utility model are：
The novel bottle cap structure that the utility model is provided, including bottleneck and bottle cap, the inner chamber roof of the bottle cap is in inside
Protrusion Clothoid type inclined plane shape.In the state of bottle cap and bottleneck closure, inner chamber roof and the bottleneck inward flange of bottle cap form line and connect
Touch to form liquid-tight envelope.Compared to prior art, bottle cap roof of the present utility model does not use annular recess, in closed closure
During, it is not required to arduously make the edge of bottleneck to enter in annular recess, so that using laborsaving, convenient.

Specific embodiment
The utility model is further described with the following Examples.
The novel bottle cap structure of the present embodiment includes bottleneck and bottle cap, and bottleneck and bottle cap are connected through a screw thread.Bottle cap it is interior
Chamber roof is in inwardly projecting Clothoid type inclined plane shape, and forms linear contact lay with bottleneck inward flange.Specifically, Fig. 1, Fig. 2 are seen, bottle cap
Inner chamber roof 1 is spheric, and bottle cap inner chamber roof 1 is provided with sealed Cellophane 2, and sealed Cellophane 2 is covered in the surface of roof 1.Sealing
The thickness of glued membrane 2 is b, b=0.7mm.Bottle cap madial wall is provided with screw thread 3, in the state of bottle cap and bottleneck 4 are closed, spheric top
Wall 1 and the linear contact lay of bottleneck inward flange 41, to form liquid-tight envelope.
In second embodiment of the present utility model（See Fig. 3）, the inner chamber roof 1 of bottle cap is cone-shaped, bottle cap with
In the state of bottleneck 4 is closed, cone-shaped roof 1 and the linear contact lay of bottleneck inward flange 41, to form liquid-tight envelope.
In the 3rd embodiment of the present utility model（See Fig. 4）, the inner chamber roof 1 of bottle cap is the second order surface of revolution, second order
Connected by the taper surface of revolution between the surface of revolution.In the state of bottle cap and bottleneck 4 are closed, the taper surface of revolution and bottleneck inward flange
41 linear contact lays, to form liquid-tight envelope.
In above three embodiment, sealed Cellophane 2 is covered in the surface of roof 1, after bottle cap is tightened, bottleneck inward flange
41 produce elastic deformation against sealed Cellophane 2 to it so that the liquid-tight envelope between bottle cap and bottleneck 4 is more effective.
Finally it should be noted that above example is only used to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained to the utility model with reference to preferred embodiment, this area it is general
It is logical it will be appreciated by the skilled person that can be modified to the technical scheme of utility model or equivalent, without deviating from this reality
With the spirit and scope of new technique scheme.
