Specific embodiment

The technical solution protected below in conjunction with attached drawing to the utility model illustrates.

Incorporated by reference to Fig. 1 to Fig. 3.The utility model proposes a kind of safe novel barrier bottles, including the bottle being used cooperatively Body 4 and bottle cap 1, the bottle body 4 include double-layer structure, i.e. outer layer ontology 6 and internal layer ontology 5, the outer layer ontology 6 and described It is provided with interval between internal layer ontology 5, to surround a confined space 100, cooling gas check valve 7 is equipped on the outer layer ontology 6, For being able to enter outside air in the confined space 100；The confined space 100 is a gas compartment；Meanwhile in institute The bottle mouth position for stating bottle body 4 is equipped with liquid non-return valve 23, and the bottle body 4 is formed by the liquid non-return valve 23 for holding content Another fluid space of object；The liquid non-return valve 23 enables content to flow out outside bottle body.

The liquid non-return valve 23 includes soft valve 2 and valve seat 3 in one of the embodiments, and the soft valve 2 is mounted on institute It states on valve seat 3.

The outer layer ontology 6 is tightly connected with the internal layer ontology 5 in bottle mouth position in one of the embodiments,；More into One step, the bottom centre of the internal layer ontology 5 and the bottom of the outer layer ontology 6 are also tightly connected, to surround described close Close space 100.

The internal layer ontology 5 is made of gas barrier material in one of the embodiments,.

Incorporated by reference to Fig. 3, the bottle cap 1 includes pedestal 10 and upper cover 11, and the pedestal 10 includes base side wall and pedestal top Wall offers internal screw thread compatible with the external screw thread of bottleneck of the bottle body 4 on the inner wall of the lower end of the base side wall, i.e., The bottle cap 1 is threadedly attached in the bottle mouth position of the bottle body 4；In other embodiments, the lower end of the base side wall is also It can be connected by buckling with the bottleneck of the bottle body, the upper cover 11 is used to open or closes bottleneck；Meanwhile described Pedestal roof offers tortuous passageway 8, and the tortuous passageway 8 includes the first passage 81 extended vertically downward and prolongs vertically upward The axis of the second channel 82 stretched, the first passage 81 and the second channel 82 is not overlapped, the first passage 81 and institute It states and is connected between second channel 82 by interface channel 80；And when bottle cap 1 is mounted on bottleneck, the liquid non-return valve 23 In in the first passage 81；So that successively passing through described first after content is flowed out by the liquid non-return valve 23 Channel 81, interface channel 80 and second channel 82 could flow out, and the first passage 81 and the second channel 82 mutually stagger, Buffer function is played to the content of outflow, content is avoided to burst out.

In addition, the inner surface of the upper cover 11 has extended downwardly sealing convex block 111, close when by the upper cover 11 lid described When on pedestal 10, the sealing convex block 111 is inserted into the second channel 82.

The course of work of the utility model is as follows: upper cover 11 opened when use, is inverted the outer layer ontology 6 of simultaneously extrusion bottle 4, The pressure in the bottle is increased, bottleneck is poured into squeeze the content in internal layer ontology 5 and the valve head deformation of soft valve 2 is pushed to transport forward It is dynamic, the valve head disengaging of soft valve 2 and fitting closely for valve seat 3；Then, start opening process, as the valve head of the soft valve 2 is into one Step travels forward until its overturning is opened, and content is gone out from the valve head incision of soft valve 2, and content fluid is described tortuous logical It turns under the action of road 8, flowed out after buffering.

When squeezing is finished, since bottle internal pressure lowers, the valve head of the soft valve 2 is rapid under itself elastic reaction It retracts, bottom surface touch 3 surface of valve seat immediately and seals the bottleneck of bottle body 4.The negative pressure in the bottle in 6 recuperation of outer layer ontology Under effect, external gas enters the confined space 100 between outer layer ontology 6 and internal layer ontology 5 by cooling gas check valve 7, from And complete the gas in bottle, stream volume-exchange, i.e., content outflow, 5 volume of internal layer ontology reduce；Outside air passes through gas unidirectional Valve 7 enters confined space 100, and to backfill the vacancy occurred because 5 volume of internal layer ontology reduces, this completes first uses Journey.By parity of reasoning, moves in circles, until the content in internal layer ontology 5 all squeezes to the greatest extent.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
