One kind barrier plastic bottleTechnical field
The present invention relates to one kind to obstruct plastic bottle.
Background technology
At present, it is more that the place of liquid is accommodated using plastic bottle, such as oil, the various flavouring of vinegar, because plastic bottle accommodatesLiquid in open bottle cover, liquid in plastic bottle will with air contact, it is apt to deteriorate, reduce fluid storage whenBetween.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, the probability of the liquid-to-air contact in reduction plastic bottle, energyEnough prevent the barrier plastic bottle of the liquid degeneration in plastic bottle.
The technical scheme is that a kind of barrier plastic bottle, it includes bottle 1 and bottleneck 2, it is characterised in that：The bottleBody 1 is made up of internal layer and outer layer and gap is left between the internal layer and outer layer of the bottle 1, in the side wall of the bottle 1 andThe outer layer of the bottle 1 is provided with barrier hole 3, and barrier plug 4 is snapped with the barrier hole 3, and the middle part of the barrier plug 4 is provided with resistanceNext door 6, the outside of the barrier plug 4 are provided with subsider 7, and the shaft core position of the barrier rib 6 is provided with through hole 10, the bottle 1Internal layer and be provided with micropore 11 with the corresponding section of 6 through hole of barrier rib 10, a domed rubber stopper 8 is arranged on the sedimentationIn groove 7, the center position of the rubber stopper 8 is provided with rubber cone 12 rubber cone 12, and to be sequentially inserted into the barrier rib 6 logicalMicropore 11 on hole 10 and the internal layer of the bottle 1.
Technical scheme can also be that the top of the bottleneck 2 is provided with rubber skirt 5, and the rubber skirt 5 is setThere is unidirectional liquid outlet, the inwall of the rubber skirt 5 is provided with one-way air inlet passage 13.
Technical scheme can also be that the outside of the through hole 10 of barrier rib 6 is additionally provided with two passages 9, describedTwo passages 9 pass through one-way air inlet passage 13 on gap between the internal layer of bottle 1 and outer layer and the rubber skirt 5Connection.
The beneficial effects of the invention are as follows by the bottle 1 be made up of internal layer and outer layer and the internal layer of the bottle 1 andLeave gap between outer layer, barrier hole 3, the barrier hole 3 are provided with the side wall of the bottle 1 and in the outer layer of the bottle 1Barrier plug 4 is inside snapped with, the middle part of the barrier plug 4 is provided with barrier rib 6, and the outside of the barrier plug 4 is provided with subsider 7, instituteThe shaft core position for stating barrier rib 6 is provided with through hole 10, the internal layer of the bottle 1 and is set with the corresponding section of 6 through hole of barrier rib 10There is micropore 11, a domed rubber stopper 8 is arranged in the subsider 7, and the center position of the rubber stopper 8 is provided with rubberThe rubber cone 12 of cone 12 is sequentially inserted into the micropore 11 on the through hole 10 of barrier rib 6 and the internal layer of the bottle 1；In use,Sequentially passed through by the rubber cone 12 of the center position of rubber stopper 8 on the through hole 10 of barrier rib 6 and the internal layer of the bottle 1Micropore 11, make to form sealing space between the internal layer and outer layer of bottle 1, when pouring out liquid, the bottom of bottle of bottle 1 is gradually upwardTilt, the liquid in bottle 1 concentrates on the top of rubber skirt 5, only somewhat need to apply external force to the outer layer of bottle 1, bottle 1Internal layer is compressed, while air is also compressed and flowed out from one-way air inlet passage 13 between the internal layer of bottle 1 and outer layer, oppresses rubberThe liquid outflow at the top of skirt 5, after removing external force, because the internal layer of bottle 1 flows out without gas, and rubber skirt 5 is unidirectionally to go outLiquid mouth, outside air cannot be introduced into the internal layer of bottle 1, realize the effect of barrier air；When bottle 1 internal layer and outer layer itBetween when requiring supplementation with air, bottle 1 is holded up, need to only apply external force to domed rubber stopper 8, due to the rubber of rubber stopper 8Cone 12 inserts the through hole 10 of barrier rib 6, and rubber stopper 8 is under the edge action of through hole 10 of barrier rib 6, the surrounding rubber cushion of rubber stopper 8Tilted from inside to outside in subsider 7, extraneous air enters the internal layer of bottle 1 by two passages 9 in the outside of the through hole 10 of barrier rib 6Between outer layer, and air cannot be introduced into the internal layer of bottle 1, be achieved in that it is simple in construction, reduce plastic bottle in liquid withThe probability of air contact, the effect of the liquid degeneration in plastic bottle can be prevented.

Embodiment
According to Fig. 1,2, the present invention relates to one kind to obstruct plastic bottle, and it includes bottle 1 and bottleneck 2, the bottle 1 byInternal layer and outer layer form and gap are left between the internal layer and outer layer of the bottle 1, in the side wall of the bottle 1 and in the bottleThe outer layer of body 1 is provided with barrier hole 3, and barrier plug 4 is snapped with the barrier hole 3, and the middle part of the barrier plug 4 is provided with barrier rib 6,The outside of the barrier plug 4 is provided with subsider 7, and the shaft core position of the barrier rib 6 is provided with through hole 10, the internal layer of the bottle 1And micropore 11 is provided with the corresponding section of 6 through hole of barrier rib 10, a domed rubber stopper 8 is arranged in the subsider 7,Provided with rubber cone 12, the rubber cone 12 is sequentially inserted into the He of 6 through hole of barrier rib 10 to the center position of the rubber stopper 8Micropore 11 on the internal layer of bottle 1；The top of the bottleneck 2 is provided with rubber skirt 5, and the rubber skirt 5 is provided with unidirectionally to go outLiquid mouth, the inwall of the rubber skirt 5 are provided with one-way air inlet passage 13, and the outside of the through hole 10 of barrier rib 6 is additionally provided with twoIndividual passage 9, described two passages 9 pass through on gap between the internal layer of bottle 1 and outer layer and the rubber skirt 5One-way air inlet passage 13 connects；In use, the barrier rib is sequentially passed through by the rubber cone 12 of the center position of rubber stopper 8Micropore 11 on 6 through holes 10 and the internal layer of the bottle 1, make to form sealing space between the internal layer and outer layer of bottle 1, pour outDuring liquid, the bottom of bottle of bottle 1 is gradually inclined upwardly, and the liquid in bottle 1 concentrates on the top of rubber skirt 5, only need to be somewhat rightThe outer layer of bottle 1 applies external force, and the internal layer of bottle 1 is compressed, at the same between the internal layer of bottle 1 and outer layer air also compressed and fromOne-way air inlet passage 13 flows out, the liquid outflow at the top of compressing rubber skirt 5, after removing external force, because the internal layer of bottle 1 is without gasBody flows out, and rubber skirt 5 is unidirectional liquid outlet, and outside air cannot be introduced into the internal layer of bottle 1, realizes barrier airEffect；When requiring supplementation with air between the internal layer and outer layer of bottle 1, bottle 1 is holded up, only need to be to domed rubber stopper 8Apply external force, because the rubber cone 12 of rubber stopper 8 inserts the through hole 10 of barrier rib 6, rubber stopper 8 is on the side of through hole 10 of barrier rib 6Under edge effect, the surrounding rubber cushion of rubber stopper 8 tilts from inside to outside in subsider 7, the outside that extraneous air passes through the through hole 10 of barrier rib 6Two passages 9 enter between the internal layer and outer layer of bottle 1, and air cannot be introduced into the internal layer of bottle 1, be achieved in that structureSimply, the probability of the liquid-to-air contact in plastic bottle is reduced, the effect of the liquid degeneration in plastic bottle can be prevented.
