Description
Technical field
The present invention relates to the closure field of a kind of bottle, particularly a kind of positive sealing bottle cap.
Background technology
Existing bottle cap is attractive in appearance for guaranteeing, generally uses the version that multiple components are combined.Wherein, when component relatively
Time many, there is the position that relatively many places needs seal, wherein the part of thread seal is relatively reliable.But such as shown in Fig. 4, its
In bottle neck and interior plug between formed by interference fit and to seal, there is problems of, when ambient temperature generation large change or
When person suffers external force, there will be gap between bottle neck and interior plug, thus cause fluid leakage.Cause quality accident.
Summary of the invention
The technical problem to be solved is to provide a kind of positive sealing bottle cap, it can be ensured that seal reliable.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: a kind of reliably seal bottle cap, including on
Lid, the inward upper cover being fastened and connected with upper cover, the bottle neck threadeded with inward upper cover, also include the lower cover being connected with bottle outer wall,
The interior plug being connected with bottle inwall, described bottle neck inwall is provided with closure gasket groove, and described interior end beyond the Great Wall is provided with annulus, described
Closure gasket groove and described annulus form the sealing of grafting and coordinate.
The hardness of interior plug material is less than the hardness of bottle neck material；
Described annulus outer wall and the outside inwall interference fit of closure gasket groove, described annulus inwall and sealing ring
The inner side outer wall interference fits of groove.
Described interior plug uses Low Density Polyethylene material, described bottle neck to use AS material.
The inwall of bottle neck is additionally provided with rib in the position near closure gasket groove, and described rib periphery is provided with multiple logical
Hole.
Described upper cover inwall is provided with multiple spacing antiturning pitch, and inward upper cover outer wall is provided with multiple corresponding antiturning pitch, upper cover
Lower end is additionally provided with the barb for hooking inward upper cover lower end.
Cover under described and be provided with false proof tooth, above cover the breach being provided with for accommodating false proof tooth.
A kind of positive sealing bottle cap that the present invention provides, in the position needing interference fit, by using closure gasket groove, joins
Close the material of different hardness, it is achieved that seal cooperation reliably.Further in the reinforcement arranged near the position of closure gasket groove
Portion improves the structural strength at closure gasket groove, it is ensured that the dimensional accuracy of closure gasket groove.The rib with through hole arranged
Also there is the effect preventing liquid splash.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the overall structure exploded perspective view of the present invention.
Fig. 2 is the schematic diagram that in the present invention, bottle neck and interior plug seal structure.
Fig. 3 is the schematic diagram that in the present invention, another kind of bottle neck and interior plug seal structure.
Fig. 4 is the schematic diagram that in prior art, bottle neck and interior plug seal structure.
In figure: upper cover 1, inward upper cover 2, bottle neck 3, interior plug 4, lower cover 5, false proof tooth 6, breach 7, spacing antiturning pitch 8, barb 9,
Closure gasket groove 10, annulus 11, rib 12, through hole 13.
Detailed description of the invention
In Fig. 1-3, a kind of positive sealing bottle cap, including upper cover 1, the inward upper cover 2 being fastened and connected with upper cover 1, in upper
Cover 2 threaded bottle necks 3, also include the lower cover 5 being connected with bottle outer wall, the interior plug 4 being connected with bottle inwall, its feature
Being: described bottle neck 3 inwall is provided with closure gasket groove 10, described interior plug 4 upper end is provided with annulus 11, described closure gasket groove 10
The sealing forming grafting with described annulus 11 coordinates.The prior art such as plastic components in Fig. 4 is when being changed by temperature
Can shrink or become big, thus sealing effectiveness completely cannot be reached, result in the accident of wine leaking, and working of plastics is by the time
Change also can produce aging, thus the absent-mindedness of one side interference fit occurs.By the structure of the present invention, when variations in temperature or bottle
When mouthful suffering external force, interior plug all can be formed with the inwall of the closure gasket groove 10 of bottle neck 3 or outer wall and combine closely, and makes the liquid will not
Leakage, it is ensured that sealing effectiveness completely, thus substantially increase sealing and the resting period of liquid.
The outside inwall interference fit of described annulus 11 outer wall and closure gasket groove 10, described annulus 11 inwall with
The inner side outer wall interference fits of closure gasket groove 10.Thus structure, coordinates sealing and has still divided primary and secondary, i.e. with annulus 11 outer wall
Cooperation be main, thus be avoided that both sides sealing uses too high quality of fit.
Described interior plug uses Low Density Polyethylene material i.e. (LDPE), and described bottle neck 3 uses AS material, i.e. propylene
Fine-styrene.Thus structure, the hardness of interior plug is less than the hardness of bottle neck 3, thus reduce further the requirement to precision, i.e.
The error of dimensional accuracy can be suitable for by the deformation of interior plug.
The inwall of bottle neck 3 is additionally provided with rib 12 in the position near closure gasket groove 10, and described rib 12 periphery sets
There is multiple through hole 13.Thus structure, this rib 12 ensure that the structural strength of closure gasket groove 10, it is ensured that dimensional accuracy is not because of certainly
The deformation of body and impacted.The multiple through hole of respective outer side edges 13 of rib 12 can also effectively prevent spilling of liquid in bottle.
Described upper cover 1 inwall is provided with multiple spacing antiturning pitch 8, and inward upper cover 2 outer wall is provided with multiple corresponding antiturning pitch, on
Cover 1 lower end and be additionally provided with the barb 9 for hooking inward upper cover 2 lower end.Thus structure, after inward upper cover 2 and upper cover 1 are nested together,
Do not destroy, be difficult to separate.
Described lower cover 5 is provided with false proof tooth 6, and upper cover 1 is provided with the breach 7 for accommodating false proof tooth 6.Thus structure,
After false proof tooth 6 is grouped together with breach 7, does not destroy false proof tooth 6 and be then difficult to open bottle cap, thus play anti-fake effect.
During use, first bottle neck 3, interior plug 4 and lower cover 5 are grouped together, in wherein bottle neck 3 is enclosed within lower cover 5, and by lower cover
5 limit its axial displacement, and the pawl in lower cover 5 is for limiting the lower cover 5 position at bottle outer wall.The lower end of interior plug 4 is then
Formed to seal with bottle inwall and coordinate.By in bottle neck 3, interior plug 4 and lower cover 5 integral installation to bottle, then screw on inward upper cover 2,
The breach 7 of upper cover 1 is directed at false proof tooth 6 on lower cover 5 depress, i.e. completes to install, during unlatching, can only be by rotating inward upper cover 2, band
Dynamic upper cover 1 destroys false proof tooth 6 ability open bottle cover, thus realizes false proof.
