Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
See Fig. 1 to Fig. 4, the preferred embodiments of the present invention provide a kind of bottle cap, comprise caping 21 and lid 22, and the inner circumferential circle of lid 22 is provided with negative thread 221, and the below inner circumferential circle of lid 22 being positioned at negative thread 221 is provided with planar seal ring 222.
As shown in Figure 1, embodiments of the invention one, bottle cap 20 is the tubular structure of lower ending opening, comprises caping 21 and lid 22.The inner circumferential circle of lid 22 is provided with negative thread 221, and the below inner circumferential circle of lid 22 being positioned at negative thread 221 is provided with planar seal ring 222.Particularly, the below inner circumferential circle of lid 22 being positioned at negative thread 221 is a step, and the interior diameter of this step is greater than the large footpath of negative thread 221, and planar seal ring 222 is arranged on this step.Preferably, the lower end of bottle cap 20 is also provided with pilfer band 23, and pilfer band 23 is connected by dowel 24 with lid 22.When opposite spin bottle cap 20, pilfer band 23 will break.In other implementations, the lower end of bottle cap 20, without pilfer band 23, to save the work material of bottle cap 20, reduces costs.
Caping 21 extends to form seal ring 211 towards lid 22 direction.Seal ring 211, slightly toward tilted, makes the lateral surface of seal ring 211 be a dip plane.
As shown in Figure 2, embodiments of the invention two, the lid 22 of bottle cap 20 is identical with the structure of the lid 22 of embodiment one, but caping 21 is without seal ring 211.
As shown in Figure 3, embodiments of the invention three, the lid 22 of bottle cap 20 and the structure of pilfer band 23 identical with embodiment one, the lower surface of caping 21 is provided with one deck packing seal 212, packing seal 212 is covered with the lower surface of whole caping 21, and packing seal 212 adopts aluminum foil pad, to ensure the health of beverage.
As shown in Figure 4, embodiments of the invention four, the lid 22 of bottle cap 20 and the structure of pilfer band 23 identical with embodiment one, the lower surface of caping 21 is provided with one deck packing seal 212, packing seal 212 is covered with the lower surface of whole caping 21, and packing seal 212 adopts instillation rubber cushion, to ensure the health of beverage.The lower end of packing seal 212 extends to form boss.
Refer to Fig. 5, the cross-sectional plane of body 10 is circular or square or other abnormity.The upper end of body 10 is provided with bottleneck 11, and usually, bottleneck 11 is the cylinder of annular.The periphery circle of bottleneck 11 is provided with tops bar 112 and get out of a predicament or an embarrassing situation 113, and the excircle of bottleneck 11 being positioned at tops bar above 112 is provided with outside thread 111; Outside thread 111 matches with negative thread 221, planar seal ring 222 contact of bottle cap 20 top bar 112 upper surface 112a.Get out of a predicament or an embarrassing situation 113 be positioned at top bar 112 lower end, when bottle cap 20 is tightened on bottleneck 11, the bottom of bottle cap 20 be positioned at get out of a predicament or an embarrassing situation 113 top.
Refer to Fig. 6, the beverage packaging of the preferred embodiments of the present invention one, comprises the bottle cap 20 of the above embodiments one and above-mentioned body 10, when bottle cap 20 is tightened on bottleneck 11, planar seal ring 222 just contact top bar 112 upper surface 112a, so that bottle cap 20 and bottleneck 11 are sealed.Because planar seal ring 222 is positioned at the lower end of negative thread 221, by the sealing of planar seal ring 222, bacterium and other impurity can be stoped to enter into the threaded connection place of bottle cap 20 and bottleneck 11, during the lip contact bottleneck 11 of bondsman, bottleneck 11 is health.When bottle cap 20 is tightened on bottleneck 11, the bottom of bottle cap 20 is positioned at gets out of a predicament or an embarrassing situation more than 113.And the port of the now dip plane contact bottleneck 11 of seal ring 211, seal with bottleneck 11 so that bottle cap 20 will be worked as, and when bottle cap 20 is pressed tighter, the better effects if of sealing.The sealing of seal ring 211 and bottleneck 11 and planar seal ring 222 with top bar 112 the sealing that formed of upper surface 112a together with, form double sealing structure, make sealing effectiveness better.
The beverage packaging of the preferred embodiments of the present invention two, comprise the bottle cap 20 of the above embodiments two and above-mentioned body 10, due to the sealing that planar seal ring 222 and the upper surface 112a that tops bar 112 are formed, be enough to the sealing completely making bottle cap 20 and bottleneck 11, therefore caping 21 place does not establish seal ring 211, to save bottle cap 20 material, and simplify the processing of bottle cap 20.
The beverage packaging of the preferred embodiments of the present invention three, comprises the bottle cap 20 of the above embodiments three and above-mentioned body 10, and when bottle cap 20 is tightened on bottleneck 11, the port of packing seal 212 contact bottleneck 11, to seal bottle cap 20 and bottleneck 11.With planar seal ring 222 with top bar 112 the sealing that formed of upper surface 112a together with, form double sealing structure, make sealing effectiveness better.
The beverage packaging of the preferred embodiments of the present invention four, comprises the bottle cap 20 of the above embodiments four and above-mentioned body 10, and when bottle cap 20 is tightened on bottleneck 11, the port of the boss contact bottleneck 11 of packing seal 212, to seal bottle cap 20 and bottleneck 11.With planar seal ring 222 with top bar 112 the sealing that formed of upper surface 112a together with, form double sealing structure, make sealing effectiveness better.
The below that beverage packaging of the present invention is positioned at negative thread 221 on the inner circumferential circle of lid 22 is provided with planar seal ring 222, with seal bottle cap 20 and bottleneck 11, avoid bacterium and fine impurities to pollute the threaded connection place of bottle cap 20 and bottleneck 11, thus avoid bacterium or fine impurities to enter into human body.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
