Fig. 1 is the structural representation of the utility model one embodiment.

Among the figure: 1. upper bottle cover; 2. polygon pillar; 3. lower bottle cap; 4. interior bottle cap; 5. bottle; 6. tubaeform inner interlayer; 7. external bottle cavity; 8. internal bottle cavity.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to accompanying drawing.Present embodiment comprises bottle 5, lower bottle cap 1, lower bottle cap 3 and interior bottle cap 4, extend a tubaeform inner interlayer 6 obliquely upward from bottle 5 madial walls, the bottle chamber is divided into external bottle cavity 7 and internal bottle cavity 8, tubaeform inner interlayer 6 tops extend to bottle mouth position by bottleneck always, captive joint with bottle mouth wall by pole again; Bottleneck outer wall is provided with outside thread, and tubaeform inner interlayer 6 upper inside wall are provided with negative thread; Upper bottle cover 1, lower bottle cap 3 and interior bottle cap 4 all have negative thread in the same way; Tubaeform inner interlayer 6 negative thread numbers are more than bottleneck outside thread number; Lower bottle cap 3 lids are tightened on the bottleneck outer wall, and its caping is an annular arrangement, and annulus open circles diameter is more tubaeform, and inner interlayer 6 top bores are bigger, are connected with a cylinder on the annulus, the caping open circles diameter of the internal diameter of cylinder and lower bottle cap 3 big or small identical; The high 1.5cm of described cylinder, the outer wall on its top is provided with outside thread, and the upper bottle cover 1 that is provided with the suitable negative thread of cylinder upper external thread can be tightened on the outer wall of described cylinder; The interior heading tape of upper bottle cover 1 has a polygon pillar 2, the length of polygon pillar 2 equals the interior distance of pushing up interior bottle cap 4 groove bottom lands of upper bottle cover 1, the groove of bottle cap 4 in the bottom of polygon pillar 2 can be inserted or extract just, bottle cap 4 rotates with upper bottle cover 1 in also can driving.

The dynamic duty principle of each bottle cap is: when turning upper bottle cover 1, a hand must be caught lower bottle cap 3 and bottle 5, prevent that lower bottle cap 3 from catching up with bottle cap 1 and moving together, because the related effect of polygon pillar 2, interior bottle cap 4 also can follow upper bottle cover 1 to rotatablely moving with the side, be upper bottle cover 1 when being back-outed, interior bottle cap 4 is also and then back-outed.After 4 two bottle caps of upper bottle cover 1 and interior bottle cap were back-outed, the liquid of internal bottle cavity 8 just can be poured out.Since lower bottle cap 3 stop that the liquid that can not in the external bottle cavity 7 is poured out; When upper bottle cover 1 was tightened, interior bottle cap 4 also and then was tightened.Played the double-ply protective effect like this.Back-outing and being screwed into of lower bottle cap 3 has two kinds of situations respectively: no matter when the sort of situation was back-outed and is screwed into, upper bottle cover 1 and lower bottle cap 3 were screw threads in the same way, a bottle cap enter or go out representing going out or advancing of another.So hand all must be pushed down the generation that upper bottle cover prevents this situation.A kind of situation is, after lower bottle cap 3 is back-outed fully, the words of no longer rotating but directly being drawn out, so, because the negative thread number of tubaeform inner interlayer 6 upper inside wall is more than bottleneck outside thread number, so also have little time to be back-outed fully, and polygon pillar 2 has been drawn out, so interior bottle cap 4 also is retained on the negative thread on tubaeform inner interlayer 6 tops.Since interior bottle cap 4 stop that the liquid that can not of internal bottle cavity 8 is poured out; So just can drink the liquid in the external bottle cavity 7; When being screwed into, lower bottle cap 3 is before the outside thread of contact bottleneck, in polygon pillar 2 has inserted in the groove of bottle cap 4---the length of polygon pillar 2 is greater than the top of the interior bottle cap 4 of this moment distance to the interior top of upper bottle cover 1, as long as lower bottle cap 3 be screwed into adjust in the process direction just can be 2 insertions of polygon pillar in the groove of bottle cap 4; Bottle cap 4 rotated together in the polygon pillar 2 of bottle cap 4 grooves just can drive under the application force that screws the cap off a bottle in inserting, thereby interior bottle cap 4 also is screwed into, and allowed three bottle caps get back to original position.Another kind of situation, after lower bottle cap 3 is back-outed fully from the bottleneck outside thread, not directly to be drawn out but the then words of idle running, polygon pillar 2 is not drawn out, and bottle cap 4 was rotated further up to interior bottle cap 4 is taken out of fully in it can drive, and lower bottle cap 3 was taken off again, three bottle caps of this moment also are one, they all have been removed so, thereby have realized that two kinds of liquid open to the outside world simultaneously, simultaneously two kinds of liquid in the drink bottle.When being screwed into, when the negative thread on the tubaeform inner interlayer of interior bottle cap 4 contacts 6 tops, just begin to rotate, up to lower bottle cap 3 also being tightened fully the position of getting back to when packing.
