Disposable cap-destroying cap
Technical field
The present invention relates to a kind of improvement of bottle bottle cap, particularly a kind of disposable cap-destroying cap.
Background technology
Existing bottle bottle cap easily comes off under the effect that is subjected to external force between connection cover and the fixed cover in the process of using, and causes bottle cap can't seal bottleneck.
Summary of the invention
Purpose of the present invention will provide a kind of disposable cap-destroying cap exactly, and it adopts at connection cover the structure that pressure cuts off boss is set, and can make bottle cap connection cover and fixed cover difficult drop-off under the effect that is subjected to external force, reaches the purpose of sealing bottleneck.
The object of the present invention is achieved like this: a kind of disposable cap-destroying cap, comprise enclosing cover, inner cap, connection cover and fixed cover, inner cap is fixed in the enclosing cover, go up outer covering and be provided with breach, false proof tooth on the false proof toothholder of breach and fixed cover is complementary, and the welding ring of connection cover bottom is provided with pressure and cuts off boss, has groove on the pressure partition boss, connection cover is captiveed joint with fixed cover by welding ring, and the false proof toothholder on the fixed cover embeds in the groove.
Owing to adopt said structure,, make bottle cap connection cover and fixed cover difficult drop-off under the effect that is subjected to external force so the external force that connection cover upward pressure partition boss can be subjected to bottle cap is disperseed; And bottle cap can twist off the false proof tooth on the fixed cover when opening, and the purpose of ruining lid that reaches can only disposablely be used bottle cap, reaches false proof purpose.
Description of drawings
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is that each block construction of the present invention is partly cutd open scheme drawing.
Fig. 2 is that the structure of the present invention when assembling partly cutd open scheme drawing.
Fig. 1 double as Figure of abstract.
Among the figure: 1, go up enclosing cover, 2, inner cap, 3, connection cover, 4, fixed cover, 5, breach, 6, welding ring, 7, pressure cuts off boss, 8, groove, 9, false proof toothholder, 10, false proof tooth, 11, interior plug.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of disposable cap-destroying cap, comprise enclosing cover 1, inner cap 2, connection cover 3 and fixed cover 4, inner cap 2 is fixed in the enclosing cover 1, and last enclosing cover 1 is provided with breach 5, and the false proof tooth 10 on breach 5 and the fixed cover 4 false proof toothholders 9 is complementary, the welding ring 6 of connection cover 3 bottoms is provided with pressure and cuts off boss 7, have groove 8 on the pressure partition boss 7, connection cover 3 is captiveed joint with fixed cover 4 by welding ring 6, and the false proof toothholder on the fixed cover 49 embeds in the grooves 8.
During assembling, earlier interior plug 11 is embedded in the connection cover 3, with bonding machine the welding ring 6 of connection cover 3 bottoms is captiveed joint with fixed cover 4 then, false proof toothholder 9 on the fixed cover 4 must be corresponding with the groove 8 that pressure cuts off on the boss 7, inner cap 2 is screwed on the connection cover 3, the breach 5 that to go up at last on the enclosing cover 1 aligns with false proof toothholder 9 on the fixed cover 4, exerts pressure inner cap 2 embedded and goes up in the enclosing cover 1.
During packing, the fixed cover 4 of bottle cap directly is enclosed within on the bottle neck gets final product.
During use, will go up enclosing cover 1 and outward winding, and false proof tooth 10 can be twisted off in the enclosing cover 1 on outwarding winding, and reach the purpose of ruining lid, the bottle cap of breaking-up can not reuse, and reaches disposable use and false proof purpose.
